[0050] Figure 1 is a structural diagram of the first display panel provided in an embodiment of the present application, Figure 2 is a schematic structural diagram of a first sub-pixel provided in an embodiment of the present application, Figure 3 yes Figure 2 The schematic diagram of the cross-sectional structure of the first sub-pixel along the section line AA' is provided, combined with Figure 1-Figure 3 As shown, the display panel provided by the embodiment of the present application includes a plurality of sub-pixels 10, the sub-pixels 10 include a first electrode 101 and a pixel emission area 102, the first electrode 101 includes a connected electrode main portion 1011 and an electrode connection portion 1012, and the pixel emission area 102 overlaps with the electrode main portion 1011; the plurality of sub-pixels 10 include a plurality of first sub-pixels 11, and the center of gravity of the electrode main portion 1011 in the first sub-pixel 11 is staggered with the center of gravity of the pixel emission area 102.

[0051] like Figure 1 As shown, the display panel includes a plurality of sub-pixels 10, and the plurality of sub-pixels 10 include sub-pixels with different luminous colors, such as a first color sub-pixel, a second color sub-pixel, and a third color sub-pixel. The luminous colors of the first color sub-pixel, the second color sub-pixel, and the third color sub-pixel are different to achieve color display of the display panel.

[0052] refer to Figure 1 and Figure 2As shown, the sub-pixel 10 may include a first electrode 101, a light-emitting layer 103, a second electrode 104 and a pixel circuit 105. The first electrode 101 may be the anode of the sub-pixel, and the second electrode 104 may be the cathode of the sub-pixel. The first electrode 101 is electrically connected to the pixel circuit 105, and is used to receive the anode signal provided by the pixel circuit 105; the second electrode 104 is used to receive the cathode signal provided by the power signal line. The light-emitting layer 103 is arranged between the first electrode 101 and the second electrode 104, and is used to emit light under the action of the anode signal and the cathode signal. The pixel circuit 105 may include transistors or capacitors, and the pixel circuit 105 may include different numbers of transistors and / or capacitors according to different setting areas. For example, the pixel circuit 105 may include two transistors and one capacitor to form a pixel circuit with a "2T1C" structure (T represents transistor, C represents capacitor); or the pixel circuit 105 may include seven transistors and one capacitor to form a pixel circuit with a "7T1C" structure. The embodiment of the present application does not limit the specific setting method of the pixel circuit 105. Figure 3 1 and a transistor exemplarily represent the pixel circuit 105 .

[0053] Furthermore, the first electrode 101 includes an electrode main body 1011 and an electrode connecting portion 1012 connected to each other. The electrode main body 1011 is the main structure of the first electrode 101 and its shape is generally a relatively regular shape, for example Figure 1 and Figure 2 The electrode connecting portion 1012 is a connecting structure between the electrode main body 1011 and the pixel circuit 103. As an auxiliary connecting portion of the first electrode 101, its area is generally small, for example, much smaller than the area of the electrode main body 1011, and its shape can be as follows: Figure 1 and Figure 2 The shape shown is similar to a "little tail".

[0054] The pixel emission region 102 can be understood as the light emitting region of the sub-pixel 10, which corresponds to the pixel opening in the sub-pixel 10, for example Figure 3In the area corresponding to the opening structure in the pixel definition layer (PDL), the light emitting layer 103 is formed at least in the pixel emission area 102. In a conventional sub-pixel structure, the center of gravity of the pixel emission area needs to be set to coincide with the center of gravity of the electrode main body. This results in a strict preparation process for the pixel opening, and a strict alignment process is required to ensure that the center of gravity of the pixel emission area coincides with the center of gravity of the electrode main body. In an embodiment of the present application, a plurality of sub-pixels 10 are provided including a first sub-pixel 11. The first sub-pixel 11 is a sub-pixel 10 having a different luminous color than one or at least two of the sub-pixels 10. In the first sub-pixel 11, the center of gravity O' of the electrode main body 1011 is staggered with the center of gravity O of the pixel emission area 102, that is, along the light emitting direction of the display panel or the thickness direction of the display panel, the center of gravity O' of the electrode main body 1011 does not coincide with the center of gravity O of the pixel emission area 102. This can reduce the difficulty of alignment between the pixel emission area 102 and the electrode main body 1011, reduce the process difficulty of preparing pixel openings in the pixel defining layer, and thereby reduce the difficulty of preparing the display panel and improve the preparation efficiency of the display panel.

[0055] Based on the above embodiment, a specific implementation of the first shape of the first sub-pixel will be described below. Figure 4 is a schematic structural diagram of a second first sub-pixel provided in an embodiment of the present application, Figure 5 is a schematic structural diagram of the third first sub-pixel provided in an embodiment of the present application, Figure 6 is a schematic structural diagram of the fourth first sub-pixel provided in an embodiment of the present application, Figure 7 is a schematic structural diagram of the fifth first sub-pixel provided in an embodiment of the present application, Figure 8 is a schematic structural diagram of a sixth first sub-pixel provided in an embodiment of the present application, Figure 9 is a schematic structural diagram of the seventh first sub-pixel provided in an embodiment of the present application, Figure 10 is a schematic structural diagram of an eighth first sub-pixel provided in an embodiment of the present application, Figure 11 is a schematic structural diagram of the ninth first sub-pixel provided in an embodiment of the present application, Figure 4-11 The structure of the first sub-pixel shown only shows the shape of the pixel emission area 102. Figure 4-11 As shown, the pixel emission area 102 has a first shape 20; the first shape 20 of the first sub-pixel 11 includes at least one first shape segment 201 and at least one second shape segment 202, at least the first shape segment 201 includes a curve, and the curvature of at least some of the line segments in the second shape segment 202 is different from the curvature of the first shape segment 201; the two ends of the same first shape segment 201 are connected to the two ends of the same second shape segment 202, or, the two ends of the same first shape segment 201 are connected to different second shape segments 202.

[0056] Combine Figure 4-11 As shown, the first shape 20 of the first sub-pixel 11 includes at least one first shape segment 201 and at least one second shape segment 202. The first shape segment 201 and the second shape segment 202 can be understood as two shapes with different curvatures. At least the first shape segment 202 includes a curve. For example, the first shape segment 201 may include an arc-shaped curve. The dotted line shown in the figure is the trajectory of the virtual circle in which the first shape segment 201 is located when the first shape segment 201 is an arc-shaped curve. The second shape segment 202 may include a curve, a straight line, or both a curve and a straight line. Furthermore, the curvature at different positions in the same second shape segment may be the same or different. By adjusting the shape of the first shape segment 201 and / or the second shape segment 202, the center of gravity position of the pixel emission area 102 of the first sub-pixel 11 can be adjusted, so as to realize a scheme in which the center of gravity of the electrode main body 1011 in the first sub-pixel 11 and the center of gravity of the pixel emission area 102 are staggered. Moreover, by adjusting the shape of the first shape segment 201 and / or the second shape segment 202, the center of gravity of the pixel emission area 102 can be flexibly adjusted, thereby ensuring that the center of gravity adjustment method of the pixel emission area 102 is simple and flexible, and optimizing the display effect.

[0057] Furthermore, the first shape 20 of the same first sub-pixel 11 may include at least one first shape segment 201 and at least one second shape segment 202. By adjusting the number of the first shape segments 201 and the second shape segments 202, the center of gravity of the electrode main body 1011 in the first sub-pixel 11 and the center of gravity of the pixel emission area 102 can be staggered. Moreover, by adjusting the number of the first shape segments 201 and / or the second shape segments 202, the center of gravity adjustment method of the pixel emission area 102 can be flexible and diverse.

[0058] For further reference, Figure 4-10 As shown, the first shape 20 of the first sub-pixel 11 includes a first shape segment 201 and a second shape segment 202 , and two ends of the same first shape segment 201 are connected to two ends of the same second shape segment 202 .

[0059] refer to Figures 4-10 As shown, the first shape 20 of the same first sub-pixel 11 includes a first shape segment 201 and a second shape segment 202. That is, for the first shape 20 of the same first sub-pixel 11, the two ends of the same first shape segment 201 are connected to the two ends of the same second shape segment 202. In this way, the center of gravity position of the pixel emission area 102 of the first sub-pixel 11 can be adjusted by adjusting the shape of the first shape segment 201 and / or the second shape segment 202.

[0060] For further reference, Figure 4 、 Figure 5 、 Figure 7-Figure 9 As shown, the first shape segment 201 may include a curve segment with a continuously changing curvature, and the second shape segment 202 may include a curve segment with a continuously changing curvature, that is, the different boundary contours of the first shape are all curves. In this way, the first shape can be ensured to be relatively rounded, and there will be no light diffraction problem caused by the sudden change in curvature, thereby ensuring the luminous effect of the first sub-pixel.

[0061] For further reference, Figure 6 As shown, the connection points of the first shape segment 201 and the second shape segment 202 include a first connection point P1 and a second connection point P2; the first shape segment 201 includes a curve segment with continuously changing curvature, and the second shape segment 202 includes a straight line segment, and the first connection point P1 and the second connection point P2 are located on the straight line segment.

[0062] like Figure 6 As shown, the first shape 20 includes a first shape segment 201 with continuously changing curvature and a second shape segment 202 with a straight line segment. The setting of the curved segment combined with the straight line segment can enrich the first shape, ensuring that the pixel emission area of the first sub-pixel can have a variety of feasible shapes to match the different shape requirements of the pixel emission area.

[0063] For further reference, Figure 7 、 Figure 8 and Figure 9 As shown, the second shape segment 202 includes at least two sub-segments, and different sub-segments have different curvatures.

[0064] like Figure 7 and Figure 8 As shown, the second shape segment 202 includes two sub-segments with different curvatures, namely a first sub-segment 2021 and a second sub-segment 2022, wherein: Figure 7 The first sub-segment 2021 and the second sub-segment 2022 are both located on the side of the virtual curve 30 away from the first shape segment. Figure 8 The first sub-segment 2021 is located on the side of the virtual curve 30 away from the first shape segment, and the second sub-segment 2022 is located on the side of the virtual curve 30 close to the first shape segment. Figure 9 As shown, second shape segment 202 includes three sub-segments with different curvatures, namely, first sub-segment 2021, second sub-segment 2022, and third sub-segment 2023. Providing second shape segment 202 with at least two sub-segments with different curvatures can enrich second shape segment 202, and thus enrich the shape of first shape 20, ensuring that the pixel emission area of the first sub-pixel can have a variety of feasible shapes to match different shape requirements of the pixel emission area.

[0065] For further reference, Figure 9As shown, the first shape segment 201 includes a curve segment with a continuously changing curvature, and the second shape segment 202 includes at least one straight line segment and at least one curve segment with a continuously changing curvature.

[0066] like Figure 9 As shown, the second shape segment 202 includes a portion with continuously changing curvature and a straight line segment portion. The setting of the curved segment combined with the straight line segment can further enrich the second shape segment 202, and then enrich the shape of the first shape 20, ensuring that the pixel emission area of the first sub-pixel can have a variety of feasible shapes to match the different shape requirements of the pixel emission area.

[0067] On the basis of the above embodiments, continue to refer to Figure 4-Figure 9 As shown, the connection points of the first shape segment 201 and the second shape segment 202 include a first connection point P1 and a second connection point P2, and the line between the first connection point P1 and the second connection point P2 is a first line P1P2; the display panel also includes a virtual curve 30, the two ends of the virtual curve 30 are connected to the first shape segment 201 at the first connection point P1 and the second connection point P2, the virtual curve 30 and the first shape segment 201 are arranged cocentrically, and the virtual curve 30 and the first shape segment 201 are located on different sides of the first line P1P2; at least a portion of the second shape segment 202 is staggered with the virtual curve 30.

[0068] refer to Figure 4-Figure 9 As shown, the connection points of the first shape segment 201 and the second shape segment 202 include a first connection point P1 and a second connection point P2. The first connection point P1 and the second connection point P2 can be understood as the dividing points between the first shape segment 201 and the second shape segment 202. The display panel also includes a virtual curve 30, which is arranged cocentrically with the first shape segment 201. That is, the virtual curve 30 and the first shape segment 201 both partially overlap with the arc trajectory of the virtual circle in which the first shape segment 201 is located, or in other words, the virtual curve 30 and the first shape segment 201 are both partial arc trajectories of the virtual circle in which the first shape segment 201 is located. Without considering the alignment error, the center of the virtual circle in which the first shape segment 201 is located coincides with the center of gravity of the electrode body 1011. Since the first shape 20 of the pixel emission area 102 includes a first shape segment 201 and a second shape segment 202, and in the embodiment of the present application, at least a portion of the second shape segment 202 is set to be staggered with the virtual curve 30, this can ensure that the center of gravity O of the pixel emission area 102 and the electrode main body O' are staggered, thereby reducing the difficulty of alignment between the pixel emission area 102 and the electrode main body 1011, thereby reducing the difficulty of preparing the display panel and improving the preparation efficiency of the display panel.

[0069] On the basis of the above embodiments, continue to refer to Figure 4 、 Figure 6 、 Figure 8 and Figure 9 As shown, at least some line segments in the second shape segment 202 are located on a side of the virtual curve 30 close to the first shape segment 201 .

[0070] in, Figure 4 、 Figure 6 and Figure 9 Assuming that all line segments in the second shape segment 202 are located on the side of the virtual curve 30 close to the first shape segment 201, the center of gravity O of the pixel emission region is located on the side close to the first shape segment 201 relative to the center of gravity O' of the electrode main body. That is, the center of gravity O of the pixel emission region is offset relative to the center of gravity O' of the electrode main body toward the side close to the first shape segment 201. Furthermore, Figure 8 Some line segments in the second shape segment 202 are located on the side of the virtual curve 30 close to the first shape segment 201, and the remaining parts are located on the side of the virtual curve 30 away from the first shape segment 201, and the part of the second shape segment 202 close to the first shape segment 201 and the part away from the first shape segment 201 have different degrees of offset relative to the virtual curve 30. At this time, it can also be ensured that the center of gravity O of the pixel emission area and the center of gravity O' of the electrode main body are staggered.

[0071] On the basis of the above embodiments, continue to refer to Figure 4 、 Figure 6 and Figure 9 As shown, in the first sub-pixel, the center of gravity O of the pixel emission area is located on the side of the center O' of the virtual circle where the first shape segment is located close to the first shape segment 201.

[0072] like Figure 4 、 Figure 6 and Figure 9 As shown, without considering the alignment error, the center of the virtual circle where the first shape segment 201 is located coincides with the center of gravity of the electrode body 1011, for example, both can be represented by O' as shown in the figure. Figure 4 、 Figure 6 and Figure 9 In the figure, the center of gravity O of the pixel emission area is located on the side of the center O' of the virtual circle where the first shape segment is located, close to the first shape segment 201, that is, the center of gravity O of the pixel emission area is offset toward the side of the first shape segment 201 relative to the center O' of the virtual circle where the first shape segment is located, so as to reduce the difficulty of alignment between the pixel emission area 102 and the electrode main body 1011.

[0073] On the basis of the above embodiments, continue to refer to Figure 5 、 Figure 7 and Figure 8As shown, at least some of the line segments in the second shape segment 202 are located on a side of the virtual curve 30 away from the first shape segment 201 .

[0074] in, Figure 5 and Figure 7 All line segments in the second shape segment 202 are located on the side of the virtual curve 30 away from the first shape segment 201. At this time, the center of gravity O of the pixel emission area is located on the side away from the first shape segment 201 relative to the center of gravity O' of the electrode main body. That is, the center of gravity O of the pixel emission area is offset relative to the center of gravity O' of the electrode main body toward the side away from the first shape segment 201. Furthermore, Figure 8 Some line segments in the second shape segment 202 are located on the side of the virtual curve 30 away from the first shape segment 201, and the remaining parts are located on the side of the virtual curve 30 close to the first shape segment 201, and the part of the second shape segment 202 close to the first shape segment 201 and the part away from the first shape segment 201 have different degrees of offset relative to the virtual curve 30. At this time, it can also be ensured that the center of gravity O of the pixel emission area and the center of gravity O' of the electrode main body are staggered.

[0075] On the basis of the above embodiments, continue to refer to Figure 8 As shown, some line segments in the second shape segment 202 are located on the side of the virtual curve 30 close to the first shape segment 201, and some line segments are located on the side of the virtual curve 30 away from the first shape segment 201. In addition, the portion of the second shape segment 202 close to the first shape segment 201 and the portion away from the first shape segment 201 have different degrees of offset relative to the virtual curve 30. Figure 8 Taking the shown figure as an example, the second shape segment 202 includes a first sub-segment 2021 and a second sub-segment 2022 with different curvatures, wherein the protrusion of the first sub-segment 2021 relative to the virtual curve 30 is smaller than the recessed degree of the second sub-segment 2022 relative to the virtual curve 30, and combined with the arc length of the first sub-segment 2021 and the arc length of the second sub-segment 2022, it can be achieved to ensure that the center of gravity O of the pixel emission area and the center of gravity O' of the electrode main body are staggered.

[0076] On the basis of the above embodiments, continue to refer to Figure 4-Figure 6 as well as Figure 8-Figure 9 As shown, the connection points of the first shape segment 201 and the second shape segment 202 include a first connection point P1 and a second connection point P2, and the line between the first connection point P1 and the second connection point P2 is a first line P1P2; the maximum length of the first shape segment 201 in a direction parallel to the extension direction of the first line P1P2 is greater than the length of the first line P1P2, and the maximum length of the second shape segment 202 in a direction parallel to the extension direction of the first line is equal to the length of the first line P1P2.

[0077] like Figure 4-Figure 6 as well as Figure 8-Figure 9 As shown, the line P1'P2' with the longest length in the direction parallel to the extension direction of the first line P1P2 in the first shape segment 201 is P1'P2', where the length of the line P1'P2' is greater than the length of the first line P1P2. That is, there are two points P1' and P2' in the first shape segment 201, and the extension direction of the line connecting these two points P1' and P2' is parallel to the extension direction of the first line P1P2. Moreover, the length of the line connecting these two points P1' and P2' is greater than the length of the first line P1P2. Considering that the first shape segment 201 includes a curve, this ensures that the first shape segment 201 has a longer curve length, or in other words, the arc length of the first shape segment 201 is longer. In other words, the length of the first shape segment 201 accounts for a larger proportion of the entire boundary length of the first shape 20. That is, the boundary of the first shape 20, compared to the boundary of the virtual circle containing the first shape segment 201, the portion that undergoes shape change, namely the second shape segment 202, accounts for a smaller proportion; the portion that does not undergo shape change, namely the first shape segment 201, accounts for a larger proportion. This ensures that, while the center of gravity O' of the electrode body 1011 is staggered from the center of gravity O of the pixel emission area 102, the shape change of the pixel emission area 102 is also minimal, which has little impact on the normal light-emitting shape of the first sub-pixel, ensuring normal light emission of the first sub-pixel.

[0078] On the basis of the above embodiments, continue to refer to Figure 4-Figure 6 as well as Figure 8-Figure 9 As shown, the connection points of the first shape segment 201 and the second shape segment 202 include a first connection point P1 and a second connection point P2, and the line between the first connection point P1 and the second connection point P2 is a first line P1P2; the first shape segment 201 is divided by the first line P1P2 into a first sub-part part1 including the first shape segment and a second sub-part part2 including the second shape segment; the area of the first sub-part part1 is larger than the area of the second sub-part part2.

[0079] like Figure 4-Figure 6 as well as Figure 8-Figure 9As shown, the first shape segment 201 is divided by the first connecting line P1P2 into a first sub-portion part1 including the first shape segment and a second sub-portion part2 including the second shape segment, and the area of the first sub-portion part1 is larger than the area of the second sub-portion part2. That is, for the pixel emission area, the area corresponding to the portion that does not undergo shape change, that is, the first shape segment 201, is larger than the area corresponding to the portion that undergoes shape change, that is, the second shape segment 202. That is, the area change rate of the entire pixel emission area is relatively small. In this way, it is ensured that, under the premise of staggering the center of gravity O' of the electrode main body 1011 and the center of gravity O of the pixel emission area 102, the area change of the pixel emission area 102 is relatively small, which has little impact on the normal light-emitting area of the first sub-pixel, thereby ensuring normal light emission of the first sub-pixel.

[0080] On the basis of the above embodiments, continue to refer to Figure 4-Figure 6 as well as Figure 8-Figure 9 As shown, the connection points of the first shape segment 201 and the second shape segment 202 include a first connection point P1 and a second connection point P2, and the line between the first connection point P1 and the second connection point P2 is a first line P1P2; the maximum vertical distance H between each point on the first shape segment 201 and the first line P1P2 is greater than the maximum vertical distance H' between each point on the second shape segment 202 and the first line P1P2.

[0081] like Figure 4-Figure 6 as well as Figure 8 As shown, the maximum vertical distance H between each point on the first shape segment 201 and the first connecting line P1P2 is greater than the maximum vertical distance H' between each point on the second shape segment 202 and the first connecting line P1P2. That is, for the pixel emission area, the portion that does not undergo shape change, that is, the maximum length of the first shape segment 201 in the vertical direction of the first connecting line P1P2, is greater than the portion that undergoes shape change, that is, the maximum length of the second shape segment 202 in the vertical direction of the first connecting line P1P2. In other words, the rate of change in the length of the entire pixel emission area in the vertical direction of the first connecting line P1P2 is not large. This ensures that, while the center of gravity O' of the electrode main body 1011 is staggered from the center of gravity O of the pixel emission area 102, the overall deformation of the pixel emission area 102 is kept small, which has little impact on the normal luminous shape of the first sub-pixel, thereby ensuring normal luminescence of the first sub-pixel.

[0082] On the basis of the above embodiments, continue to refer to Figure 4-Figure 6 as well as Figure 8-Figure 9As shown, the connection points of the first shape segment 201 and the second shape segment 202 include a first connection point P1 and a second connection point P2; the connection line between the first connection point and the center O' of the virtual circle where the first shape segment is located is the second connection line P1O', and the connection line between the second connection point P2 and the center O' of the virtual circle is the third connection line P2O'; the angle between the second connection line P1O' and the third connection line P2O' toward the side of the first shape segment 201 is θ1, and the angle between the second connection line P1O' and the third connection line P2O' toward the side of the second shape segment is θ2; wherein, θ1>θ2.

[0083] like Figure 4-Figure 6 as well as Figure 8-Figure 9 As shown, the angle between the second connecting line P1O' and the third connecting line P2O' toward the first shape segment 201 is greater than the angle between the second connecting line P1O' and the third connecting line P2O' toward the second shape segment. That is, for the pixel emission area, the arc center angle corresponding to the portion that has not undergone shape change, that is, the first shape segment 201, is greater than the arc center angle corresponding to the portion that has undergone shape change, that is, the second shape segment 202. That is, the portion of the entire pixel emission area that has undergone shape change does not account for a large proportion of the arc center angle. This ensures that, under the premise of staggering the center of gravity O' of the electrode main body 1011 and the center of gravity O of the pixel emission area 102, the overall deformation of the pixel emission area 102 can be kept small, which has little impact on the normal luminous shape of the first sub-pixel, thereby ensuring normal luminescence of the first sub-pixel.

[0084] Furthermore, 120°≤θ2<180°, for example, θ2 can be 120°, 123°, 128°, 132°, 135°, 140°, 148°, 149°, 154°, 158°, 160°, 165°, 170°, 172°, 175° or 178°. The embodiment of the present application does not limit the data value of θ2. By reasonably setting the numerical range of θ2, the roundness of the pixel emission area in the first sub-pixel can be further guaranteed, and the light diffraction problem and color deviation problem of the first sub-pixel will not be caused, thereby ensuring the light emitting effect of the first sub-pixel.

[0085] Furthermore, 130°≤θ2≤150°, and furthermore, θ2=140°. In this way, the roundness of the pixel emission area in the first sub-pixel is fully guaranteed, thereby ensuring the luminous effect of the first sub-pixel.

[0086] Based on the above embodiments, Figure 10 is a schematic structural diagram of the ninth first sub-pixel provided in an embodiment of the present application, such as Figure 10As shown, the connection points of the first shape segment 201 and the second shape segment 202 include a first connection point P1 and a second connection point P2, and the line between the first connection point P1 and the second connection point P2 is a first line P1P2; the first point P3 on the first shape segment 201 has a maximum vertical distance from the first line P1P2, and the second point P4 on the second shape segment has a maximum vertical distance from the first line P1P2; the length of the line between the first point P3 and the center O' of the virtual circle where the first shape segment 201 is located is R1, and the length of the line between the second point and the center of the virtual circle where the first shape segment is located is R2; wherein, R1>R2.

[0087] like Figure 10 As shown, the third point P3 can be understood as the point on the first shape segment 201 with the greatest distance from the first connecting line P1P2, and the fourth point P4 can be understood as the point on the second shape segment 202 with the greatest distance from the first connecting line P1P2. The length R1 of the line between the first point P3 and the center point O' of the virtual circle containing the first shape segment 201 and the length R2 of the line between the second point P3 and the center point of the virtual circle containing the first shape segment satisfy R1>R2. That is, the point P3 on the first shape segment 201 with the greatest distance from the first connecting line P1P2 is closer to the center point O' of the virtual circle containing the first shape segment 201 than the point P4 on the second shape segment 202 with the greatest distance from the first connecting line P1P2. In other words, compared with the virtual curve 30, the second shape segment 202 is offset as a whole toward the side close to the first shape segment 201, ensuring that the center of gravity O of the pixel emission area in the first sub-pixel and the center of gravity O' of the electrode main body can be staggered, thereby reducing the difficulty of aligning the center of gravity O of the pixel emission area in the first sub-pixel and the center of gravity O' of the electrode main body.

[0088] It should be noted that Figure 10 Only a feasible first shape structure is used as an example for illustration. It can be understood that Figure 4 、 Figure 6 as well as Figure 9 The structure of the first shape shown is also applicable to the solution where the length of the line between the first point and the center of the virtual circle where the first shape segment is located is greater than the length of the line between the second point and the center of the virtual circle where the first shape segment is located, which will not be repeated here.

[0089] Furthermore, 0.75≤R2 / R1≤0.95, that is, the ratio between R2 and R1 is between 0.75-0.95. For example, R2 / R1 can be 0.75, 0.78, 0.80, 0.83, 0.85, 0.88, 0.90, 0.92 or 0.95. The embodiment of the present application does not limit the data value of R2 / R1. The ratio of R2 / R1 can limit the degree of deviation of the second shape segment 202 compared with the virtual curve 30, and can also limit the area of the pixel emission area and the roundness of the first shape. Setting 0.75≤R2 / R1≤0.95, that is, the degree of deviation of the second shape segment 202 compared with the virtual curve 30 is not too large, which can ensure that the degree of reduction in the area of the pixel emission area is not too large, and the roundness of the first shape does not change much, which will not affect the light emitting effect of the first sub-pixel, will not cause the light diffraction problem and color deviation problem of the first sub-pixel, and ensure the light emitting effect of the first sub-pixel.

[0090] Furthermore, 0.85<R2 / R1≤0.95, and even further, R2 / R1=0.9. In this way, the luminous area and roundness of the pixel emission region in the first sub-pixel are fully guaranteed, thereby ensuring the luminous effect of the first sub-pixel.

[0091] Continue to refer Figure 11 As shown, the first shape 20 of the first sub-pixel 11 includes at least two first shape segments 201 and at least two second shape segments 202; the two ends of the same first shape segment 201 are connected to different second shape segments 202, and the two ends of the same second shape segment 202 are connected to different first shape segments 201.

[0092] like Figure 11 As shown, in the first shape 20 of the first sub-pixel 11, the number of first shape segments 201 can be at least two, the number of second shape segments 202 can be at least two, the two second shape segments 202 connected to the same first shape segment 201 can have the same or different curvatures, and the two first shape segments 201 connected to the same second shape segment 201 can have the same or different curvatures. By adjusting the number and position of the first shape segments 201, as well as the number and position of the second shape segments 202, the center of gravity of the pixel emission area in the first sub-pixel can be flexibly adjusted to ensure that the center of gravity O of the pixel emission area in the first sub-pixel and the center of gravity O' of the electrode main body can be staggered, thereby reducing the difficulty of aligning the center of gravity O of the pixel emission area in the first sub-pixel with the center of gravity O' of the electrode main body.

[0093] Further, Figure 12 is a schematic structural diagram of the tenth first sub-pixel provided in an embodiment of the present application, Figure 12The difference from the structure of the first sub-pixel in the above embodiment is that the first shape 20 of the first sub-pixel 11 includes at least two second shape segments 202 with different curvatures, and the different second shape segments 202 are closer to or offset from the center of gravity O' of the electrode main body to different degrees. By adjusting the shape of the second shape segment 202 and its relative positional relationship with the center of gravity O' of the electrode main body, the center of gravity of the pixel emission area in the first sub-pixel can be flexibly adjusted to ensure that the center of gravity O of the pixel emission area in the first sub-pixel and the center of gravity O' of the electrode main body can be staggered, reducing the difficulty of aligning the center of gravity O of the pixel emission area in the first sub-pixel with the center of gravity O' of the electrode main body.

[0094] To sum up, the above embodiments illustrate the specific implementation method of the first shape of a single first sub-pixel. By reasonably setting the first shape, it can be ensured that the center of gravity of the pixel emission area in the first sub-pixel and the center of gravity of the electrode main body are staggered, thereby reducing the difficulty of aligning the center of gravity of the pixel emission area in the first sub-pixel and the center of gravity of the electrode main body, reducing the process difficulty in the display panel preparation process, and improving the preparation efficiency of the display panel.

[0095] Based on the above embodiment, the arrangement of a plurality of different first sub-pixels will be described below.

[0096] Figure 13 This is a schematic diagram of the structure of the first sub-pixel group provided in an embodiment of the present application, combined with Figure 1 and Figure 13 As shown, the display panel provided by the embodiment of the present application also includes a plurality of first sub-pixel groups 31, the first sub-pixel group 31 includes a plurality of first sub-pixels with the same luminous color, the plurality of first sub-pixels include a first first sub-pixel 111, a second first sub-pixel 112, a third first sub-pixel 113, a fourth first sub-pixel 114 and a fifth first sub-pixel 115; the first first sub-pixel 111, the second first sub-pixel 112, the third first sub-pixel 113 and the fourth first sub-pixel 114 constitute a first virtual quadrilateral 41, the centers of gravity of the first first sub-pixel 111, the second first sub-pixel 112, the third first sub-pixel 113 and the fourth first sub-pixel 114 are respectively located at the four vertices of the first virtual quadrilateral 41, and the fifth first sub-pixel 115 is located inside the first virtual quadrilateral 41; the center of gravity of the pixel emission area of the fifth first sub-pixel 115 is O 15 and the center of gravity O of the pixel emission area of the first sub-pixel 111 11 The line between them is the fourth line O 11 O 15 , the center of gravity O of the pixel emission area of the fifth first sub-pixel 115 15 and the center of gravity O of the pixel emission area of the second first sub-pixel 112 12 The line between them is the fifth line O12 O 15 , the center of gravity O of the pixel emission area of the fifth first sub-pixel 115 15 and the center of gravity O of the pixel emission area of the third first sub-pixel 113 13 The line between them is the sixth line O 13 O 15 , the center of gravity O of the pixel emission area of the fifth first sub-pixel 115 15 and the center of gravity O of the pixel emission area of the fourth first sub-pixel 114 14 The line between them is the seventh line O 14 O 15 ; Fourth line O 11 O 15 、The fifth line O 12 O 15 、The sixth line O 13 O 15 And the seventh line O 14 O 15 are roughly the same length.

[0097] like Figure 1 and Figure 13 As shown, the display panel provided in the embodiment of the present application further includes a plurality of first sub-pixel groups 31. The first sub-pixel group 31 includes a first first sub-pixel 111, a second first sub-pixel 112, a third first sub-pixel 113, a fourth first sub-pixel 114, and a fifth first sub-pixel 115, which emit the same luminous color. The first first sub-pixel 111 and the second first sub-pixel 112 are located in the same sub-pixel row and are the two closest first sub-pixels of the same color; the third first sub-pixel 113 and the fourth first sub-pixel 114 are located in the same sub-pixel row and are the two closest first sub-pixels of the same color; and the fifth first sub-pixel 115 is located in a sub-pixel row. Furthermore, the pixel row where the first first sub-pixel 111 is located, the pixel row where the fifth first sub-pixel 115 is located, and the pixel row where the third first pixel 113 is located are the three sub-pixel rows that contain first sub-pixels and are closest to each other. Furthermore, the first first sub-pixel 111, the second first sub-pixel 112, the third first sub-pixel 113, and the fourth first sub-pixel 114 form a first virtual quadrilateral 41. The centers of gravity of the first first sub-pixel 111, the second first sub-pixel 112, the third first sub-pixel 113, and the fourth first sub-pixel 114 are respectively located at the four vertices of the first virtual quadrilateral 41, and the fifth first sub-pixel 115 is located inside the first virtual quadrilateral 41. In addition, the center of gravity O of the pixel emission area of the fifth first sub-pixel 115 is 15 The lines connecting the four vertices of the first virtual quadrilateral 41 are respectively the fourth line O 11 O 15 、The fifth line O 12 O 15、The sixth line O 13 O 15 and the seventh line O 14 O 15 The lengths of the four lines are roughly the same, that is, the lengths of the four lines are the same or similar. For example, the fourth line O 11 O 15 、The fifth line O 12 O 15 、The sixth line O 13 O 15 And the seventh line O 14 O 15 The length of the fourth line O is roughly the same. 11 O 15 、The fifth line O 12 O 15 、The sixth line O 13 O 15 And the seventh line O 14 O 15 The ratio of any connecting line to the other connecting lines is between 0.8 and 1.2. This ensures that the centers of gravity of the five first sub-pixels corresponding to the first sub-pixel group 31 are evenly distributed, thereby facilitating display uniformity of the first sub-pixels and further achieving display uniformity of the entire display panel.

[0098] Based on the above embodiment, the fourth line O 11 O 15 、The fifth line O 12 O 15 、The sixth line O 13 O 15 And the seventh line O 14 O 15 The maximum length is L1 and the minimum length is L2; wherein, (L1-L2) / L1≤5%.

[0099] In other words, the maximum length L1 and the minimum length L2 of the four lines satisfy (L1-L2) / L1≤5%, meaning the maximum length difference of the four lines is within 5%. This further ensures that the centers of gravity of the five first sub-pixels in the first sub-pixel group 31 are evenly distributed, further improving the display uniformity of the first sub-pixels and the display uniformity of the entire display panel.

[0100] Continue to refer Figure 13 As shown, in the first virtual quadrilateral 41, the first first sub-pixel 111 and the third first sub-pixel 113 are arranged diagonally, and the second first sub-pixel 112 and the fourth first sub-pixel 114 are arranged diagonally; the center of gravity of the pixel emission area of the first first sub-pixel 111 is O 11and the center of gravity O of the pixel emission area of the third first sub-pixel 113 13 The line between them is the eighth line O 11 O 13 The center of gravity of the pixel emission area of the second first sub-pixel 112 is O 12 and the center of gravity O of the pixel emission area of the fourth first sub-pixel 114 14 The line between them is the ninth line O 12 O 14 ; The eighth line O 11 O 13 Connect with the ninth line O 12 O 14 The intersection between them is the first intersection O”; the center of gravity of the pixel emission area of the fifth first sub-pixel is O 15 It is staggered with the first intersection point O".

[0101] In other words, the first intersection point O" can be understood as the intersection point of the diagonal lines of the first virtual quadrilateral 41. The center of gravity O of the fifth first sub-pixel 115 located in the first virtual quadrilateral 41 is 15 The first intersection O" is staggered, that is, the center of gravity O of the fifth first sub-pixel 115. 15 It is not the intersection of the diagonals of the first virtual quadrilateral 41. The first virtual quadrilateral 41 is an irregular virtual quadrilateral, and the intersection of its diagonals is not the geometric center or center of gravity of the first virtual quadrilateral 41. Set the center of gravity of the pixel emission area of the fifth first sub-pixel O 15 The intersection of the diagonal lines of the first virtual quadrilateral 41 is staggered to facilitate the realization of the center of gravity O of the pixel emission area of the fifth first sub-pixel. 15 The length of the lines connecting the four vertices of the first virtual quadrilateral 41 is substantially the same, which facilitates uniform arrangement of the plurality of first sub-pixels in the first sub-pixel group and facilitates display uniformity of the first sub-pixels.

[0102] Based on the above embodiments, Figure 14 This is a schematic diagram of the structure of the second sub-pixel group provided in an embodiment of the present application, combined with Figure 1 and Figure 14As shown, the display panel also includes a plurality of second sub-pixel groups 32, the second sub-pixel group 32 includes a plurality of second sub-pixels 12 with the same luminous color, and the center of gravity O' of the electrode main body of the second sub-pixel 12 coincides with the center of gravity of the pixel emission area O; the plurality of second sub-pixels 12 include a first second sub-pixel 121, a second second sub-pixel 122, a third second sub-pixel 123, a fourth second sub-pixel 124 and a fifth second sub-pixel 125; the first second sub-pixel 121, the second second sub-pixel 122, the third second sub-pixel 123 and the fourth second sub-pixel 124 constitute a second virtual quadrilateral 42, the centers of gravity of the first second sub-pixel 121, the second second sub-pixel 122, the third second sub-pixel 123 and the fourth second sub-pixel 124 are respectively located at the four vertices of the second virtual quadrilateral 42, and the fifth second sub-pixel 125 is located inside the second virtual quadrilateral 42; the center of gravity O of the pixel emission area of the fifth second sub-pixel 125 25 and the center of gravity O of the pixel emission area of the first and second sub-pixels 121 21 The line between them is the tenth line O 21 O 25 , the center of gravity O of the pixel emission area of the fifth second sub-pixel 125 25 and the center of gravity O of the pixel emission area of the second sub-pixel 122 22 The line between them is the eleventh line O 22 O 25 , the center of gravity O of the pixel emission area of the fifth second sub-pixel 125 25 and the center of gravity O of the pixel emission area of the third second sub-pixel 123 23 The line between them is the twelfth line O 23 O 25 , the center of gravity O of the pixel emission area of the fifth second sub-pixel 125 25 and the center of gravity O of the pixel emission area of the fourth second sub-pixel 124 24 The line between them is the thirteenth line O 24 O 25 ; The tenth line O 21 O 25 、Eleventh Connection O 22 O 25 , the twelfth line O 23 O 25 And the thirteenth connection O 24 O 25 The maximum length is L3 and the minimum length is L4; wherein, (L3-L4) / L3≤5%.

[0103] like Figure 1 and Figure 14As shown, the display panel provided in the embodiment of the present application further includes a plurality of second subpixel groups 32, the second subpixel group 32 including a first second subpixel 121, a second second subpixel 122, a third second subpixel 123, a fourth second subpixel 124, and a fifth second subpixel 125, each emitting the same color. The first second subpixel 121 is located in a subpixel row; the second second subpixel 122, the fifth second subpixel 125, and the third second subpixel 123 are located in the same subpixel row, and the second second subpixel 122, the fifth second subpixel 125, and the third second subpixel 123 are the three closest second subpixels of the same color in the same subpixel row; the fourth second subpixel 124 is located in a subpixel row; the subpixel row where the first second subpixel 121 is located, the subpixel row where the second second subpixel 122, the fifth second subpixel 125, and the third second subpixel 123 are located, and the subpixel row where the fourth second subpixel 124 is located are the three subpixel rows containing second subpixels and being closest to each other. Furthermore, the first second sub-pixel 121, the second second sub-pixel 122, the third second sub-pixel 123, and the fourth second sub-pixel 124 form a second virtual quadrilateral 42. The centers of gravity of the first second sub-pixel 121, the second second sub-pixel 122, the third second sub-pixel 123, and the fourth second sub-pixel 124 are respectively located at the four vertices of the second virtual quadrilateral 42, and the fifth second sub-pixel 125 is located inside the second virtual quadrilateral 42. In addition, the center of gravity of the pixel emission area of the fifth second sub-pixel 125 is O 25 The lines connecting the four vertices of the second virtual quadrilateral 42 are the tenth line O 21 O 25 、Eleventh Connection O 22 O 25 , the twelfth line O 23 O 25 and the thirteenth line O 24 O 25 The lengths of the four lines are roughly the same, that is, the lengths of the four lines are the same or similar. For example, the tenth line O 21 O 25 、Eleventh Connection O 22 O 25 , the twelfth line O 23 O 25 and the thirteenth line O 24 O 25 The length of the tenth line O is roughly the same. 21 O 25 、Eleventh Connection O 22 O 25 , the twelfth line O 23 O 25 and the thirteenth line O 24 O 25The ratio of any connecting line to the other connecting lines is between 0.8 and 1.2. This ensures that the centers of gravity of the five second sub-pixels corresponding to the second sub-pixel group 32 are evenly distributed, thereby facilitating display uniformity of the second sub-pixels and further achieving display uniformity of the entire display panel.

[0104] Furthermore, the tenth line O 21 O 25 、Eleventh Connection O 22 O 25 , the twelfth line O 23 O 25 and the thirteenth line O 24 O 25 The maximum length L3 and the minimum length L4 satisfy (L3-L4) / L3≤5%, meaning the maximum length difference of the four connecting lines is within 5%. This further ensures that the centers of gravity of the five second sub-pixels in the second sub-pixel group 32 are evenly distributed, further improving the display uniformity of the second sub-pixels and the display uniformity of the entire display panel.

[0105] Furthermore, the fourth line O 11 O 15 、The fifth line O 12 O 15 、The sixth line O 13 O 15 And the seventh line O 14 O 15 At least one of the tenth line O is approximately equal to 21 O 25 、Eleventh Connection O 22 O 25 , the twelfth line O 23 O 25 And the thirteenth connection O 24 O 25 At least one of them. That is, the length of the line between the center of gravity of the first sub-pixel located in the first virtual quadrilateral 41 and the vertex of the first virtual quadrilateral 41 is the same as or similar to the length of the line between the center of gravity of the second sub-pixel located in the second virtual quadrilateral 42 and the vertex of the second virtual quadrilateral 42. For example, the ratio of the length of any line between the center of gravity of the first sub-pixel located in the first virtual quadrilateral 41 and the vertex of the first virtual quadrilateral 41 to the length of any line between the center of gravity of the second sub-pixel located in the second virtual quadrilateral 42 and the vertex of the second virtual quadrilateral 42 is between 0.8 and 1.2. In this way, under the premise of ensuring that multiple first sub-pixels and multiple second sub-pixels are evenly distributed and the display uniformity is good, the color mixing effect of sub-pixels of different colors is guaranteed to be good, and the color display effect of the display panel is guaranteed to be good.

[0107] like Figure 15 and Figure 16As shown, the display panel includes a plurality of third subpixel groups 33, and the third subpixel group 33 includes a sixth first subpixel 116, a seventh first subpixel 117, an eighth first subpixel 118, and a ninth first subpixel 119, which emit the same luminous color. The sixth first subpixel 116 is located in a subpixel row; the seventh first subpixel 117 and the ninth first subpixel 119 are located in the same subpixel row, and the seventh first subpixel 117 and the ninth first subpixel 119 are the two closest first subpixels of the same color in the same subpixel row; the eighth first subpixel 118 is located in a subpixel row; and the subpixel row where the sixth first subpixel 116 is located, the subpixel row where the seventh first subpixel 117 and the ninth first subpixel 119 are located, and the subpixel row where the eighth first subpixel 118 is located are the three subpixel rows that contain first subpixels and are closest to each other. Furthermore, the sixth first sub-pixel 116, the seventh first sub-pixel 117, the eighth first sub-pixel 118, and the ninth first sub-pixel 119 form a third virtual quadrilateral 43, and the centers of gravity of the sixth first sub-pixel 116, the seventh first sub-pixel 117, the eighth first sub-pixel 118, and the ninth first sub-pixel 119 are respectively located at the four vertices of the third virtual quadrilateral 43. Furthermore, the shape of the pixel emission area of the first sub-pixel includes a curved first shape segment 201. For the sixth first sub-pixel 116, the center of gravity of its pixel emission area O 16 The direction pointing to the first shape segment 201 is the first direction X1; for the seventh first sub-pixel 117, the center of gravity of its pixel emission area O 17 The direction pointing to the first shape segment 201 is the second direction X2; for the eighth first sub-pixel 118, the center of gravity of its pixel emission area O 18 The direction pointing to the first shape segment 201 is the third direction X3; for the ninth first sub-pixel 119, the center of gravity of its pixel emission area O 19 The direction pointing to the first shape segment 201 is the fourth direction X4; in the embodiment of the present application, the direction in which the center of gravity of the pixel emission area points to the first shape segment can also be understood as the protruding direction of the first shape segment relative to the center of gravity of the pixel emission area. In the embodiment of the present application, the first direction X1, the second direction X2, the third direction X3 and the fourth direction X4 are different. Figure 16 For example, the first direction X1, the second direction X2, the third direction X3 and the fourth direction X4 are distributed in the four directions of up, down, left and right, which is beneficial to avoid the four-directional color deviation of the display panel and improve the display effect of the display panel.

[0108] For further reference, Figure 15 and Figure 16As shown, the sixth first sub-pixel 116, the seventh first sub-pixel 117, the eighth first sub-pixel 118 and the ninth first sub-pixel 119 are arranged along a first clockwise direction, where the first clockwise direction may be a clockwise direction or a counterclockwise direction. Figure 16 Taking the first clockwise direction as an example, when the sixth first sub-pixel 116, the seventh first sub-pixel 117, the eighth first sub-pixel 118, and the ninth first sub-pixel 119 are arranged along the first clockwise direction, the first direction X1, the second direction X2, the third direction X3, and the fourth direction X4 are also arranged along the first clockwise direction. That is, the second direction X2 is rotated 90° along the first clockwise direction relative to the first direction X1, the third direction X3 is rotated 90° along the first clockwise direction relative to the second direction X2, and the fourth direction X4 is rotated 90° along the first clockwise direction relative to the third direction X3. This ensures that the centers of gravity of the sixth first sub-pixel 116, the seventh first sub-pixel 117, the eighth first sub-pixel 118, and the ninth first sub-pixel 119 are uniformly distributed, thereby preventing color shift in all four directions of the display panel and improving the display quality of the display panel.

[0109] Figure 17 is a schematic structural diagram of a plurality of third sub-pixel groups provided in an embodiment of the present application, such as Figure 15 and 17As shown, two third sub-pixel groups 33 adjacently arranged along the extension direction of the sub-pixel row (the X direction shown in the figure) include a first third sub-pixel group 33-1 and a second third sub-pixel group 33-2; the position of the sixth first sub-pixel 116 in the first third sub-pixel group 33-1 in the third virtual quadrilateral 43 is the same as the position of the sixth first sub-pixel 116 in the second third sub-pixel group 33-2 in the third virtual quadrilateral 43, and the first direction X1 in the first third sub-pixel group 33-1 is opposite to the first direction X1 in the second third sub-pixel group 33-2; the position of the seventh first sub-pixel 117 in the first third sub-pixel group 33-1 in the third virtual quadrilateral 43 is the same as the position of the seventh first sub-pixel 117 in the second third sub-pixel group 33-2 in the third virtual quadrilateral 43, and the first third sub-pixel group 33 -1 is opposite to the second direction X2 in the second-third sub-pixel group 33-2; the position of the eighth first sub-pixel 118 in the first-third sub-pixel group 33-1 in the third virtual quadrilateral 43 is the same as the position of the eighth first sub-pixel 118 in the second-third sub-pixel group 33-2 in the third virtual quadrilateral 43, and the third direction X3 in the first-third sub-pixel group 33-1 is opposite to the third direction X3 in the second-third sub-pixel group 33-2; the position of the ninth first sub-pixel 119 in the first-third sub-pixel group 33-1 in the third virtual quadrilateral 43 is the same as the position of the ninth first sub-pixel 119 in the second-third sub-pixel group 33-2 in the third virtual quadrilateral 43, and the fourth direction X4 in the first-third sub-pixel group 33-1 is opposite to the fourth direction X4 in the second-third sub-pixel group 33-2.

[0110] like Figure 15 and 17 As shown, the display panel includes a plurality of third sub-pixel groups 33, and the plurality of third sub-pixel groups 33 include a first third sub-pixel group 33-1 and a second third sub-pixel group 33-2 that are adjacently arranged in the extension direction X of the sub-pixel row. The first third sub-pixel group 33-1 and the second third sub-pixel group 33-2 share a first sub-pixel, that is, there is a first sub-pixel that is located in both the first third sub-pixel group 33-1 and the second third sub-pixel group 33-2. Figure 17For example, the seventh first sub-pixel 117 in the first third sub-pixel group 33-1 also serves as the ninth first sub-pixel 119 in the second third sub-pixel group 33-2. Furthermore, in the first third sub-pixel group 33-1 and the second third sub-pixel group 33-2, the two first sub-pixels with the same position have their pixel emission areas with centers of gravity pointing to opposite directions of the first shape segment 201, that is, in the first third sub-pixel group 33-1 and the second third sub-pixel group 33-2, the two first directions X1 are opposite, the two second directions X2 are opposite, the two third directions X3 are opposite, and the two fourth directions X4 are opposite. Figure 17 As shown in the figure, for example, in the first-third sub-pixel group 33-1, the first direction X1 points to the right, and in the second-third sub-pixel group 33-2, the first direction X1 points to the left; in the first-third sub-pixel group 33-1, the second direction X2 points to the lower direction, and in the second-third sub-pixel group 33-2, the second direction X2 points to the upper direction; in the first-third sub-pixel group 33-1, the third direction X3 points to the left direction, and in the second-third sub-pixel group 33-2, the third direction X3 points to the right direction; in the first-third sub-pixel group 33-1, the fourth direction X4 points to the upper direction, and in the second-third sub-pixel group 33-2, the fourth direction X4 points to the lower direction. That is, for the first third subpixel group 33-1, the sixth first subpixel 116, the seventh first subpixel 117, the eighth first subpixel 118, and the ninth first subpixel 119, which are arranged in the first clockwise direction, have their first direction X1, second direction X2, third direction X3, and fourth direction X4 also arranged in the first clockwise direction. For the second third subpixel group 33-2, the sixth first subpixel 116, the seventh first subpixel 117, the eighth first subpixel 118, and the ninth first subpixel 119, which are arranged in the first clockwise direction, have their first direction X1, fourth direction X4, third direction X3, and second direction X2 arranged in the second clockwise direction. That is, for two third subpixel groups adjacent to each other in the extension direction X of the subpixel row, the centers of gravity of the multiple first subpixels are evenly distributed, and the centers of gravity of the pixel emissive areas point in different directions toward the first shape segment 201. This prevents four-way color shift and ensures the display quality of the display panel.

[0111] For further reference, Figure 17As shown, two third sub-pixel groups adjacently arranged along the extension direction of the sub-pixel column (the Y direction shown in the figure) include a third third sub-pixel group 33-3 and a fourth third sub-pixel group 33-4; the extension direction Y of the sub-pixel column intersects the extension direction X of the sub-pixel row; the position of the sixth first sub-pixel 116 in the third third sub-pixel group 33-3 in the third virtual quadrilateral 43 is the same as the position of the sixth first sub-pixel 116 in the fourth third sub-pixel group 33-4 in the third virtual quadrilateral 43, and the first direction X1 in the third third sub-pixel group 33-3 is opposite to the first direction X1 in the fourth third sub-pixel group 33-4; the position of the seventh first sub-pixel 117 in the third third sub-pixel group 33-3 in the third virtual quadrilateral 43 is the same as the position of the seventh first sub-pixel 117 in the fourth third sub-pixel group 33-4 in the third virtual quadrilateral 43, And the second direction X2 in the third third sub-pixel group 33-3 is opposite to the second direction X2 in the fourth third sub-pixel group 33-4; the position of the eighth first sub-pixel 118 in the third third sub-pixel group 33-3 in the third virtual quadrilateral 43 is the same as the position of the eighth first sub-pixel 118 in the fourth third sub-pixel group 33-4 in the third virtual quadrilateral 43, and the third direction X3 in the third third sub-pixel group 33-3 is opposite to the third direction X3 in the fourth third sub-pixel group 33-4; the position of the ninth first sub-pixel 119 in the third third sub-pixel group 33-3 in the third virtual quadrilateral 43 is the same as the position of the ninth first sub-pixel 119 in the fourth third sub-pixel group 33-4 in the third virtual quadrilateral 43, and the fourth direction X4 in the third third sub-pixel group 33-3 is opposite to the fourth direction X4 in the fourth third sub-pixel group 33-4.

[0112] like Figure 15 and 17 As shown, the display panel includes a plurality of third sub-pixel groups 33, and the plurality of third sub-pixel groups 33 include a third third sub-pixel group 33-3 and a fourth third sub-pixel group 33-4 that are adjacently arranged in the extension direction Y of the sub-pixel column. The third third sub-pixel group 33-3 and the fourth third sub-pixel group 33-4 share a first sub-pixel, that is, there is a first sub-pixel that is located in both the third third sub-pixel group 33-3 and the fourth third sub-pixel group 33-4. Figure 17For example, the eighth first sub-pixel 118 in the third third sub-pixel group 33-3 also serves as the sixth first sub-pixel 116 in the fourth third sub-pixel group 33-4. Furthermore, in the third third sub-pixel group 33-3 and the fourth third sub-pixel group 33-4, the two first sub-pixels with the same position have their pixel emission areas with centers of gravity pointing to opposite directions of the first shape segment 201, that is, in the third third sub-pixel group 33-3 and the fourth third sub-pixel group 33-4, the two first directions X1 are opposite, the two second directions X2 are opposite, the two third directions X3 are opposite, and the two fourth directions X4 are opposite. Figure 17 As shown in the example, in the third third sub-pixel group 33-3, the first direction X1 is the direction pointing to the right, and in the fourth third sub-pixel group 33-4, the first direction X1 is the direction pointing to the left; in the third third sub-pixel group 33-3, the second direction X2 is the direction pointing to the lower side, and in the fourth third sub-pixel group 33-4, the second direction X2 is the direction pointing to the upper side; in the third third sub-pixel group 33-3, the third direction X3 is the direction pointing to the left side, and in the fourth third sub-pixel group 33-4, the third direction X3 is the direction pointing to the right side; in the third third sub-pixel group 33-3, the fourth direction X4 is the direction pointing to the upper side, and in the fourth third sub-pixel group 33-4, the fourth direction X4 is the direction pointing to the lower side. That is, for the third sub-pixel group 33-3, the sixth first sub-pixel 116, the seventh first sub-pixel 117, the eighth first sub-pixel 118, and the ninth first sub-pixel 119, which are arranged in the first clockwise direction, have their first direction X1, second direction X2, third direction X3, and fourth direction X4 also arranged in the first clockwise direction. For the fourth sub-pixel group 33-4, the sixth first sub-pixel 116, the seventh first sub-pixel 117, the eighth first sub-pixel 118, and the ninth first sub-pixel 119, which are arranged in the first clockwise direction, have their first direction X1, fourth direction X4, third direction X3, and second direction X2 arranged in the second clockwise direction. That is, for two adjacent third sub-pixel groups arranged in the extension direction Y of the sub-pixel column, the centers of gravity of the multiple first sub-pixels are evenly distributed, and the centers of gravity of the pixel emission areas point in different directions toward the first shape segment 201. This prevents four-way color shift and ensures the display quality of the display panel.

[0113] On the basis of the above embodiments, continue to refer to Figure 16 and Figure 17 As shown, the first direction X1 is the extension direction X of the sub-pixel row, such as the horizontal direction shown in the figure. Alternatively, Figure 18 is a structural diagram of a third display panel provided in an embodiment of the present application, Figure 19 : is a schematic structural diagram of the second third sub-pixel group provided in an embodiment of the present application, such as Figure 18 and Figure 19As shown, the first direction X1 intersects with the extending direction X of the sub-pixel row.

[0114] like Figures 15-19 As shown, the first direction X1 in the embodiment of the present application can include multiple different directions, that is, the direction in which the center of gravity of the pixel emission area points to the first shape segment can have multiple possible directions, so that the offset direction of the center of gravity of the first sub-pixel relative to the center of gravity of the electrode main body can have multiple possible directions, and the shape adjustment of the pixel emission area of the first sub-pixel has multiple possible ways, ensuring that the shape adjustment of the pixel emission area of the first sub-pixel is flexible and diverse to match different needs. Specifically, as Figure 15 、 Figure 16 and Figure 17 As shown, the first direction X1 may be the extension direction X of the sub-pixel row; Figure 18 and Figure 19 As shown, the first direction X1 may intersect with the extending direction X of the sub-pixel rows.

[0115] For further reference, Figure 18 and Figure 19 As shown, the angle α between the first direction X1 and the extension direction of the sub-pixel row can satisfy 30°≤α≤60°. For example, α can be considered as any angle value between 30°-60°, such as 30°, 33°, 37°, 40°, 42.5°, 45°, 48°, 51°, 53.8°, 55°, 57.2°, or 60°. The angle between the first direction X1 and the extension direction of the sub-pixel row can be flexibly set according to actual needs.

[0116] Furthermore, α=45°. In this case, the four-way color deviation adjustment effect is better, which can fully guarantee the display effect of the display panel.

[0117] Based on the above embodiments, Figure 20 is a schematic structural diagram of a fourth display panel provided in an embodiment of the present application. Figure 21 : is a schematic structural diagram of the third sub-pixel group and the fourth sub-pixel group provided in an embodiment of the present application, such as Figure 20 and Figure 21As shown, the display panel further includes a plurality of fourth sub-pixel groups 34, the fourth sub-pixel group 34 includes a plurality of first sub-pixels having the same luminescent color, the plurality of first sub-pixels include a tenth first sub-pixel 1110, an eleventh first sub-pixel 1111, a twelfth first sub-pixel 1112, and a thirteenth first sub-pixel 1113, and the luminescent colors of the tenth first sub-pixel 1110, the eleventh first sub-pixel 1111, the twelfth first sub-pixel 1112, and the thirteenth first sub-pixel 1113 are the same as those of the sixth first sub-pixel 116, the seventh first sub-pixel 117, and the fourth sub-pixel 118. The luminous colors of the eighth first sub-pixel 118 and the ninth first sub-pixel 119 are different; the tenth first sub-pixel 1110, the eleventh first sub-pixel 1111, the twelfth first sub-pixel 1112 and the thirteenth first sub-pixel 1113 form a fourth virtual quadrilateral 44, and the centers of gravity of the tenth first sub-pixel 1110, the eleventh first sub-pixel 1111, the twelfth first sub-pixel 1112 and the thirteenth first sub-pixel 1113 are respectively located at the four vertices of the fourth virtual quadrilateral 44; the pixel emission area has a first shape 20, and the first shape of the first sub-pixel The shape includes at least one first shape segment 201, and the first shape segment 201 includes a curve; in the tenth first sub-pixel 1110, the direction in which the center of gravity of the pixel emission area points to the first shape segment 201 is the fifth direction X5; in the eleventh first sub-pixel 1111, the direction in which the center of gravity of the pixel emission area points to the first shape segment 201 is the sixth direction X6; in the twelfth first sub-pixel 1112, the direction in which the center of gravity of the pixel emission area points to the first shape segment 201 is the seventh direction X7; in the thirteenth first sub-pixel 113, the direction in which the center of gravity of the pixel emission area points to the first shape segment 201 is the seventh direction X8. The direction of a shape segment 201 is the eighth direction X8; wherein, the tenth first sub-pixel 1110, the eleventh first sub-pixel 1111, the twelfth first sub-pixel 1112 and the thirteenth first sub-pixel 1113 are arranged along the second clockwise direction, and the sixth direction X5 is rotated 90° along the second clockwise direction relative to the fifth direction X5, the seventh direction X7 is rotated 90° along the second clockwise direction relative to the sixth direction X6, and the eighth direction X8 is rotated 90° along the second clockwise direction relative to the seventh direction X7; the second clockwise direction is the same as or opposite to the first clockwise direction.

[0118] like Figure 20 and Figure 21As shown, the display panel includes a plurality of fourth subpixel groups 34, and the fourth subpixel group 34 includes a tenth first subpixel 1110, an eleventh first subpixel 1111, a twelfth first subpixel 1112, and a thirteenth first subpixel 1113, which emit the same luminous color. The tenth first subpixel 1110 is located in a subpixel row; the eleventh first subpixel 1111 and the thirteenth first subpixel 1113 are located in the same subpixel row, and the eleventh first subpixel 1111 and the thirteenth first subpixel 1113 are the two closest first subpixels of the same color in the same subpixel row; the twelfth first subpixel 1112 is located in a subpixel row; and the subpixel row where the tenth first subpixel 1110 is located, the subpixel row where the eleventh first subpixel 1111 and the thirteenth first subpixel 1113 are located, and the subpixel row where the twelfth first subpixel 1112 is located are the three subpixel rows that contain first subpixels and are closest to each other. Furthermore, the tenth first sub-pixel 1110, the eleventh first sub-pixel 1111, the twelfth first sub-pixel 1112, and the thirteenth first sub-pixel 1113 form a fourth virtual quadrilateral 44, and the centers of gravity of the tenth first sub-pixel 1110, the eleventh first sub-pixel 1111, the twelfth first sub-pixel 1112, and the thirteenth first sub-pixel 1113 are respectively located at the four vertices of the fourth virtual quadrilateral 44. Furthermore, the shape of the pixel emission area of the first sub-pixel includes a curved first shape segment 201. For the tenth first sub-pixel 1110, the center of gravity of its pixel emission area O 110 The direction pointing to the first shape segment 201 is the fifth direction X5; for the eleventh first sub-pixel 1111, the center of gravity of its pixel emission area O 111 The direction pointing to the first shape segment 201 is the sixth direction X6; for the twelfth first sub-pixel 1112, the center of gravity of its pixel emission area O 112 The direction pointing to the first shape segment 201 is the seventh direction X7; for the thirteenth first sub-pixel 1113, the center of gravity of its pixel emission area O 113 The direction pointing to the first shape segment 201 is the eighth direction X8; in the embodiment of the present application, the direction in which the center of gravity of the pixel emission area points to the first shape segment can also be understood as the convex direction of the first shape segment relative to the center of gravity of the pixel emission area. In the embodiment of the present application, the fifth direction X5, the sixth direction X6, the seventh direction X7 and the eighth direction X8 are different. Figure 21 For example, the fifth direction X5, the sixth direction X6, the seventh direction X7 and the eighth direction X8 are distributed in the four directions of up, down, left and right, which is beneficial to avoid the four-directional color deviation of the display panel and improve the display effect of the display panel.

[0119] For further reference, Figure 20 and Figure 21As shown, the tenth first sub-pixel 1110, the eleventh first sub-pixel 1111, the twelfth first sub-pixel 1112 and the thirteenth first sub-pixel 1113 are arranged along the second clockwise direction, where the second clockwise direction can be clockwise or counterclockwise, that is, the second clockwise direction can be the same as or opposite to the first clockwise direction. Figure 20 and Figure 21 Taking the second clockwise direction as the clockwise direction, that is, the second clockwise direction being the same as the first clockwise direction, for example, when the tenth first sub-pixel 1110, the eleventh first sub-pixel 1111, the twelfth first sub-pixel 1112, and the thirteenth first sub-pixel 1113 are arranged along the first clockwise direction, the fifth direction X5, the sixth direction X6, the seventh direction X7, and the eighth direction X8 are also arranged along the first clockwise direction. That is, the sixth direction X6 is rotated 90° along the first clockwise direction relative to the fifth direction X5, the seventh direction X7 is rotated 90° along the first clockwise direction relative to the sixth direction X6, and the eighth direction X8 is rotated 90° along the first clockwise direction relative to the seventh direction X7. While ensuring a uniform distribution of the centers of gravity of the tenth first sub-pixel 1110, the eleventh first sub-pixel 1111, the twelfth first sub-pixel 1112, and the thirteenth first sub-pixel 1113, four-way color shift of the display panel can be avoided, thereby improving the display quality of the display panel.

[0120] Furthermore, the second clockwise direction is the same as the first clockwise direction; the sixth first sub-pixel 116 and the tenth first sub-pixel 1110 are located in the same sub-pixel row and are adjacent to each other along the extension direction of the sub-pixel row, and the first direction X1 and the fifth direction X5 are the same; the seventh first sub-pixel 117 and the eleventh first sub-pixel 1111 are located in the same sub-pixel row and are adjacent to each other along the extension direction of the sub-pixel row, and the second direction X2 and the sixth direction X6 are the same; the eighth first sub-pixel 118 and the twelfth first sub-pixel 1112 are located in the same sub-pixel row and are adjacent to each other along the extension direction of the sub-pixel row, and the third direction X3 and the seventh direction X7 are the same; the ninth first sub-pixel 119 and the thirteenth first sub-pixel 1113 are located in the same sub-pixel row and are adjacent to each other along the extension direction of the sub-pixel row, and the fourth direction X4 and the eighth direction X8 are the same.

[0121] like Figure 20 and Figure 21As shown, the second clockwise direction is the same as the first clockwise direction. The figure takes the second clockwise direction and the first clockwise direction as an example for explanation. Optionally, the second clockwise direction and the first clockwise direction can also be counterclockwise. In this case, the first direction X1 and the fifth direction X5 are the same. The figure takes the first direction X1 and the fifth direction X5 as an example for explanation. The second direction X2 and the sixth direction X6 are the same. The figure takes the second direction X2 and the sixth direction X6 as an example for explanation. The third direction X3 and the seventh direction X7 are the same. The figure takes the third direction X3 and the seventh direction X7 as an example for explanation. The fourth direction X4 and the eighth direction X8 are the same. The figure takes the fourth direction X4 and the seventh direction X7 as an example for explanation. Further, the sixth first sub-pixel 116 and the tenth first sub-pixel 1110 are two first sub-pixels with different luminous colors located in the same sub-pixel row and adjacent to each other along the extension direction of the sub-pixel row; the seventh first sub-pixel 117 and the eleventh first sub-pixel 1111 are two first sub-pixels with different luminous colors located in the same sub-pixel row and adjacent to each other along the extension direction of the sub-pixel row; the eighth first sub-pixel 118 and the twelfth first sub-pixel 1112 are two first sub-pixels with different luminous colors located in the same sub-pixel row and adjacent to each other along the extension direction of the sub-pixel row; the ninth first sub-pixel 119 and the thirteenth first sub-pixel 1113 are two first sub-pixels with different luminous colors located in the same sub-pixel row and adjacent to each other along the extension direction of the sub-pixel row. The four first sub-pixels in the third sub-pixel group 33 and the four first sub-pixels in the fourth sub-pixel group 34 are set to have the same setting method. The same setting method here can be understood as the center of gravity of the pixel emission area in the first sub-pixel at the same position points to the same direction of the first shape segment. On the premise of ensuring that the four first sub-pixels in the third sub-pixel group 33 and the fourth sub-pixel group 34 have a uniform distribution of the center of gravity, it can also be ensured that the first sub-pixels of different colors in the third sub-pixel group 33 and the fourth sub-pixel group 34 have the same or similar color mixing effects, avoiding the problem of uneven color mixing or color deviation, and ensuring the balance of the overall display of the display panel.

[0122] Based on the above embodiments, Figure 22 is a structural diagram of the fifth display panel provided in an embodiment of the present application, such as Figure 3 and 22 As shown, the display panel provided by the embodiment of the present application also includes a light-emitting layer 103 located on one side of the first electrode 101. Along the thickness direction of the display panel, the light-emitting layer 103 covers the pixel emission area 102; in the first sub-pixel 11, the center of gravity of the light-emitting layer 103 is staggered with the center of gravity of the pixel emission area 102.

[0123] Combine Figure 3 and Figure 22As shown, the display panel further includes a light-emitting layer 103 disposed between the first electrode 101 and the second electrode 104. The light-emitting layer 103 is configured to emit light in response to an anode signal and a cathode signal. The light-emitting layer 103 herein can be understood as a layer where holes and electrons recombine to generate light and heat. Furthermore, the light-emitting layer 103 can be a layer that emits colored light, such as a red light-emitting layer, a green light-emitting layer, or a blue light-emitting layer. The light-emitting layer 103 can also be a layer that emits white light. The specific color of the light emitted by the light-emitting layer is not limited in this embodiment of the present application.

[0124] Furthermore, without considering the alignment error during the display panel manufacturing process, the center of gravity of the light-emitting layer 103 is staggered with the center of gravity of the pixel emission area 102, and the center of gravity of the light-emitting layer 103 can coincide with the center of gravity of the electrode main body 1011. That is, when the shape of the pixel emission area 102 changes, the shape of the light-emitting layer 103 can remain unchanged, that is, the shape of the light-emitting layer 103 does not change with the change in the shape of the pixel emission area 102. The mask used to prepare the light-emitting layer in this way can use the mask used when the shape of the pixel emission area 102 does not change, which can reduce the difficulty and cost of preparing the light-emitting layer 103, and thus reduce the difficulty and cost of preparing the entire display panel.

[0125] Figure 23 : is a schematic structural diagram of a pixel emission region and a light-emitting layer of a first sub-pixel provided in an embodiment of the present application, such as Figure 22 and Figure 23 As shown, the boundary of the light-emitting layer 103 includes a quadrilateral, and the quadrilateral includes a first vertex B1 and a second vertex B1 set opposite to each other, and the center of gravity O of the pixel emission area 102 is located on the line between the first vertex B1 and the second vertex B2; the pixel emission area 102 has a first shape 20, and the first shape 20 of the first sub-pixel 11 includes at least one first shape segment 201 and at least one second shape segment 202, at least the first shape segment 201 includes a curve, and the curvature of at least part of the line segments in the second shape segment 202 is different from the curvature of the first shape segment 201; at least part of the first shape segment 201 is located on the side of the second shape segment 202 close to the first vertex B1, and at least part of the second shape segment 202 is located on the side of the first shape segment 201 close to the second vertex B2; the minimum distance between the first vertex B1 and the first shape segment 201 is smaller than the minimum distance between the second vertex B2 and the second shape segment 202.

[0126] like Figure 23As shown, the boundary of the light-emitting layer 103 may include a quadrilateral, the quadrilateral including a first vertex B1 and a second vertex B2 disposed diagonally, and the center of gravity O of the pixel emission region 102 is located on the line connecting the first vertex B1 and the second vertex B2. Furthermore, the first shape 20 of the first sub-pixel 11 includes at least one first shape segment 201 and at least one second shape segment 202, and at least a portion of the first shape segment 201 is located on a side of the second shape segment 202 closer to the first vertex B1, that is, at least a portion of the first shape segment 201 is closer to the first vertex B1 than the second shape segment 202; and at least a portion of the second shape segment 202 is located on a side of the first shape segment 201 closer to the second vertex B2, that is, at least a portion of the second shape segment 202 is closer to the second vertex B2 than the first shape segment 201. Figure 23 In the figure, except for the connection point between the first shape segment 201 and the second shape segment 202, any point in the first shape segment 201 is closer to the first vertex B1 than the second shape segment 202; and any point in the second shape segment 202 is closer to the second vertex B2 than the first shape segment 201. Furthermore, the minimum distance d1 between the first vertex B1 and the first shape segment 201 is smaller than the minimum distance d2 between the second vertex B2 and the second shape segment 202. This can be understood as the first sub-pixel 11 is formed by offsetting the second shape segment 202 on the side of the pixel emission area 102 that is closer to the second vertex B2 toward the side away from the second vertex B2, so as to adjust the center of gravity O of the pixel emission area and the center of gravity of the electrode main body to be staggered, thereby reducing the difficulty of alignment between the pixel emission area and the electrode main body in the display panel manufacturing process and improving the manufacturing efficiency of the display panel.

[0127] On the basis of the above embodiments, continue to refer to Figure 22 As shown, the multiple sub-pixels also include a first color sub-pixel 10R, a second color sub-pixel 10B and a third color sub-pixel 10G; the multiple first color sub-pixels 10R and the multiple second color sub-pixels 10B constitute a fifth virtual quadrilateral 45, the center of gravity of the first color sub-pixel 10R is at the first vertex of the fifth virtual quadrilateral 45, the center of gravity of the second color sub-pixel 10B is at the second vertex of the fifth virtual quadrilateral 45, the first vertex and the second vertex are alternate and spaced apart, and the third color sub-pixel 10G is inside the fifth virtual quadrilateral 45; the multiple third color sub-pixels 10G constitute a sixth virtual quadrilateral 46, the centers of gravity of the multiple third color sub-pixels 10G are respectively at the vertices of the sixth virtual quadrilateral 46, and the first color sub-pixel 10R or the second color sub-pixel 10B is inside the sixth virtual quadrilateral 46; the first sub-pixel 11 includes the first color sub-pixel 10R and / or the second color sub-pixel 10B.

[0128] like Figure 22 As shown, the first color sub-pixel 10R, the second color sub-pixel 10B and the third color sub-pixel 10G can represent sub-pixels of three different colors, wherein the first color sub-pixel 10R and the second color sub-pixel 10B can be one of a red sub-pixel and a blue sub-pixel respectively and are different, and the third color sub-pixel can be a green sub-pixel.

[0129] The display panel has a plurality of first-color sub-pixels 10R and a plurality of second-color sub-pixels 10B arranged in a pixel arrangement. Two first-color sub-pixels 10R and two second-color sub-pixels 10B form a fifth virtual quadrilateral 45. The center of gravity of the first-color sub-pixel 10R is located at the first vertex of the fifth virtual quadrilateral 45, and the center of the second-color sub-pixel 10B is located at the second vertex of the fifth virtual quadrilateral 45. The first and second vertices of the fifth virtual quadrilateral 45 are alternately arranged. In other words, the two first-color sub-pixels 10R and the two second-color sub-pixels 10B are arranged in a 2*2 arrangement. After the arrangement, the lines connecting the centers of gravity of the four sub-pixels form a quadrilateral, which is defined as the fifth virtual quadrilateral 45. Two first-color sub-pixels 10R are arranged opposite each other along one diagonal of the fifth virtual quadrilateral 45 and are located at two opposite vertices of the fifth virtual quadrilateral 45. Two second-color sub-pixels 10B are arranged opposite each other along another diagonal of the fifth virtual quadrilateral 45 and are located at two other opposite vertices of the fifth virtual quadrilateral 45. The two first-color sub-pixels 10R and the two second-color sub-pixels 10B constitute the fifth virtual quadrilateral 45. A third-color sub-pixel 10G is disposed within the fifth virtual quadrilateral 45. The multiple third-color sub-pixels 10G of the display panel are arranged in a 2x2 pattern to form a sixth virtual quadrilateral 46. The centers of gravity of the third-color sub-pixels 10G are located at the vertices of the sixth virtual quadrilateral 46. That is, when the four third-color sub-pixels 10G are arranged in a 2x2 pattern, the lines connecting their centers of gravity form a quadrilateral, which is defined as the second virtual quadrilateral 15. Based on the pixel arrangement of the first color sub-pixel 10R, the second color sub-pixel 10B, and the third color sub-pixel 10G, a first color sub-pixel 10R is disposed within a portion of the sixth virtual quadrilateral 46, and a second color sub-pixel 10B is disposed within the remaining portion of the sixth virtual quadrilateral 46. This pixel arrangement ensures that the display panel has a good display effect.

[0130] Furthermore, in the embodiment of the present application, the first sub-pixel, that is, the sub-pixel whose center of gravity of the pixel emission region is offset from the electrode main body, may include at least one of the first color sub-pixel 10R and the second color sub-pixel 10B. Figure 22 The following description is made by taking the example that the first sub-pixel includes the first color sub-pixel 10R.

[0131] Continue to refer Figure 22 As shown, the fifth virtual quadrilateral 45 includes a first virtual edge 451, a second virtual edge 452, a third virtual edge 453 and a fourth virtual edge 454 connected to each other; the maximum length of the first virtual edge 451, the second virtual edge 452, the third virtual edge 453 and the fourth virtual edge 454 is L5, and the minimum length is L6; wherein, (L5-L6) / L5≤10%.

[0132] like Figure 22 As shown, the fifth virtual quadrilateral 45 includes a first virtual side 451, a second virtual side 452, a third virtual side 453 and a fourth virtual side 454 connected, wherein the lengths of the first virtual side 451, the second virtual side 452, the third virtual side 453 and the fourth virtual side 454 are approximately the same. That is, for any one of the first virtual side 451, the second virtual side 452, the third virtual side 453 and the fourth virtual side 454, the lengths of the other virtual sides are approximately the same. The "approximately the same" here can be understood as a length ratio between 0.8 and 1.2. Furthermore, the maximum length L5 and the minimum length L6 of the first virtual side 451, the second virtual side 452, the third virtual side 453 and the fourth virtual side 454 can satisfy (L5-L6) / L5≤10%, further ensuring the length consistency of the first virtual side 451, the second virtual side 452, the third virtual side 453 and the fourth virtual side 454. The first virtual side 451, the second virtual side 452, the third virtual side 453, and the fourth virtual side 454 are set to be substantially the same length, so that there are no long or short sides with significantly different lengths. This ensures a balanced distance between the first color sub-pixel 10R and the second color sub-pixel 10B, thereby ensuring uniform leakage current between the first color sub-pixel 10R and the second color sub-pixel 10B and ensuring a good display effect. Furthermore, the first virtual side 451, the second virtual side 452, the third virtual side 453, and the fourth virtual side 454 are set to be substantially the same length. This reduces restrictions on other structures when they are disposed between the first color sub-pixel 10R and the second color sub-pixel 10B, and the presence of long and short sides does not increase the difficulty of disposing other structures between the first color sub-pixel 10R and the second color sub-pixel 10B, thereby reducing the overall manufacturing difficulty of the display panel.

[0133] Specifically, Figure 24 is a structural diagram of the sixth display panel provided in an embodiment of the present application, such as Figure 24 As shown, the display panel may further include a plurality of support columns 50 ; along the thickness direction of the display panel, the support columns 50 overlap with at least one of the first virtual edge 451 , the second virtual edge 452 , the third virtual edge 453 and the fourth virtual edge 454 .

[0134] like Figure 24As shown, the display panel further includes support columns 50, which can be used to support the light-emitting layer and the evaporation mask used during the evaporation of the second electrode to prevent the evaporation mask from causing pressure damage to other structures in the display panel. Furthermore, the support columns 50 can be located in the film layer above and / or below the first electrode. The support columns 50 can be provided independently or integrated with other film layers (such as the pixel definition layer (PDL)). The embodiments of the present application do not limit the specific film layers and configuration methods of the support columns 50.

[0135] Furthermore, in order not to affect the normal light emission of the sub-pixels, the support column can be set between the sub-pixels, or in other words, along the thickness direction of the display panel, the support column overlaps with the spacing between the sub-pixels. For example, along the thickness direction of the display panel, the support column 50 overlaps with at least one of the first virtual edge 451, the second virtual edge 452, the third virtual edge 453 and the fourth virtual edge 454. Figure 24 The following description will be made by taking as an example the case where the support column 50 overlaps with the first virtual side 451 , the second virtual side 452 , the third virtual side 453 and the fourth virtual side 454 .

[0136] Since the lengths of the first virtual edge 451, the second virtual edge 452, the third virtual edge 453 and the fourth virtual edge 454 are roughly the same, when preparing the support column, there is no need to worry about the existence of the short edge causing the distance between the support column and the sub-pixel to be smaller, thereby affecting the light output of the sub-pixel. There is also no need to worry about damage to the sub-pixel during the preparation of the support column. This reduces the difficulty of limiting the position of the support, improves the process freedom of the support column, and reduces the difficulty of preparing the display panel.

[0137] It should be noted that Figure 24 In the figure, the support column 50 is shown only in the area corresponding to part of the first virtual edge 451, the second virtual edge 452, the third virtual edge 453 and the fourth virtual edge 454 as an exemplary illustration of the correspondence between the support column 50 and the first virtual edge 451, the second virtual edge 452, the third virtual edge 453 and the fourth virtual edge 454. Support columns can also be set in the areas corresponding to the remaining first virtual edge 451, the second virtual edge 452, the third virtual edge 453 and the fourth virtual edge 454, which are not all shown in the figure.

[0138] Further, Figure 25 is a structural diagram of the seventh display panel provided in the embodiment of the present application, such as Figure 25 As shown, the display panel provided by the embodiment of the present application may include a light-shielding layer (not shown in the figure) located on the light-emitting side of the sub-pixel and a plurality of light-transmitting holes 51 arranged in the light-shielding layer; along the thickness direction of the display panel, the light-transmitting holes 51 overlap with at least one of the first virtual edge, the second virtual edge, the third virtual edge and the fourth virtual edge.

[0139] Specifically, the display panel also includes a light shielding layer having an opening and a light shielding portion disposed therein, with the light shielding portion surrounding at least a portion of the opening. Along the thickness of the display panel, the opening overlaps with the pixel emission area to ensure that display light from the sub-pixel can be emitted through the opening. The light shielding portion overlaps with the area outside the pixel emission area to prevent light crosstalk between adjacent sub-pixels, thereby ensuring a normal display effect of the display panel.

[0140] Furthermore, for a display panel provided with an optical sensor, a light-transmitting hole needs to be provided in the light-shielding portion. The provision of the light-transmitting hole can ensure that light is incident on the optical sensor through the light-transmitting hole, so that the optical sensor can sense information based on the sensed optical information. For example, the optical sensor can be a light sensor. In a plan view, the light sensor overlaps with the light-transmitting hole, and visible light can pass through the light-transmitting hole. Then, the light sensor can adjust the screen brightness of the display device according to the brightness of the surrounding light. In addition, the light sensor can also be an infrared light sensor, or a fingerprint recognition sensor. The fingerprint information or palm print information can be incident on the fingerprint recognition sensor through the light-transmitting hole, so that the processing chip in the display panel can perform corresponding operations based on the fingerprint information or palm print information sensed by the fingerprint sensor.

[0141] Furthermore, in order not to affect the normal light emission of the sub-pixels, the light-transmitting hole can be set between the sub-pixels, or in other words, along the thickness direction of the display panel, the light-transmitting hole overlaps with the spacing between the sub-pixels. For example, along the thickness direction of the display panel, the light-transmitting hole 51 overlaps with at least one of the first virtual edge 451, the second virtual edge 452, the third virtual edge 453, and the fourth virtual edge 454. Figure 25 The light-transmitting hole 51 overlaps with the first virtual edge 451 , the second virtual edge 452 , the third virtual edge 453 and the fourth virtual edge 454 as an example for description.

[0142] Since the lengths of the first virtual edge 451, the second virtual edge 452, the third virtual edge 453 and the fourth virtual edge 454 are roughly the same, when preparing the light-transmitting hole, there is no need to worry about the existence of the short edge causing the distance between the light-transmitting hole and the sub-pixel to be smaller, thereby affecting the light output of the sub-pixel. There is also no need to worry about problems such as damage to the sub-pixel during the preparation of the light-transmitting hole. This reduces the difficulty of limiting the position of the light-transmitting hole, improves the process freedom of the light-transmitting hole, and reduces the difficulty of preparing the display panel.

[0143] It should be noted that Figure 25In the figure, the light-transmitting hole 51 is shown only in the areas corresponding to part of the first virtual edge 451, the second virtual edge 452, the third virtual edge 453 and the fourth virtual edge 454 as an exemplary illustration of the correspondence between the light-transmitting hole 51 and the first virtual edge 451, the second virtual edge 452, the third virtual edge 453 and the fourth virtual edge 454. Light-transmitting holes can also be set in the areas corresponding to the remaining first virtual edge 451, the second virtual edge 452, the third virtual edge 453 and the fourth virtual edge 454, which are not all shown in the figure.

[0144] Based on the above embodiments, Figure 26 is a structural diagram of the first fifth virtual quadrilateral provided in an embodiment of the present application, Figure 27 is a structural diagram of the second fifth virtual quadrilateral provided in an embodiment of the present application, Figure 26 Take the first sub-pixel including the first color sub-pixel 10R as an example for explanation. Figure 27 The following description is made by taking the example that the first sub-pixel includes the first color sub-pixel 10R and the second color sub-pixel 10B. Figure 26 and Figure 27 As shown, among the four internal angles corresponding to the fifth virtual quadrilateral 45, the opposite angles are complementary.

[0145] Because the center of gravity of the pixel emission region of at least one of the first color sub-pixel 10R and the second color sub-pixel 10B does not coincide with the center of gravity of the electrode main body, the fifth virtual quadrilateral 45 is an irregular virtual quadrilateral, that is, the fifth virtual quadrilateral 45 is a virtual quadrilateral with a non-rectangular structure. Furthermore, the four corresponding internal angles of the fifth virtual quadrilateral 45 are complementary, that is, the two diagonal angles corresponding to the same color sub-pixels are complementary. In other words, the two diagonal angles corresponding to the same color sub-pixels are not both acute angles or not both obtuse angles.

[0146] Further, such as Figure 26 As shown, the first sub-pixel 11 includes a first color sub-pixel 10R or a second color sub-pixel 10B. The four internal angles corresponding to the fifth virtual quadrilateral 45 include one acute angle, one obtuse angle, and two right angles. Furthermore, the two internal angles with the centroid of the pixel emissive area of the first sub-pixel 11 as vertices are respectively an acute angle and an obtuse angle, while the two internal angles with the centroid of the pixel emissive area of the non-first sub-pixel as vertices are both right angles. Figure 26 Take the first sub-pixel including the first color sub-pixel 10R as an example for description. Figure 26As shown, the first subpixel includes a first color subpixel 10R; the four internal angles corresponding to the fifth virtual quadrilateral include a first internal angle, a second internal angle, a third internal angle, and a fourth internal angle. The vertex of the first internal angle is the center of gravity of the pixel emission area in the first color subpixel 10R, the vertex of the second internal angle is the center of gravity of the pixel emission area in the second color subpixel 10B, the vertex of the third internal angle is the center of gravity of the pixel emission area in the first color subpixel 10R, and the vertex of the fourth internal angle is the center of gravity of the pixel emission area in the second color subpixel 10B. The first internal angle is an acute angle, the third internal angle is an obtuse angle, and the second and fourth internal angles are both right angles. For example, the first internal angle can be 89.58° and the third internal angle can be 90.42°.

[0147] like Figure 27 As shown, the first sub-pixel 11 includes a first color sub-pixel 10R and a second color sub-pixel 10B. The four internal angles corresponding to the fifth virtual quadrilateral 45 include two acute angles and two obtuse angles. The two opposite angles corresponding to the first sub-pixels of the same color include one acute angle and one obtuse angle. That is, the two opposite angles corresponding to the first color sub-pixel 10R include one acute angle and one obtuse angle, and the two opposite angles corresponding to the second color sub-pixel 10B include one acute angle and one obtuse angle.

[0148] To sum up, in the same fifth virtual quadrilateral 45, the first sub-pixel of the same color corresponds to two internal angles, which are acute angles and obtuse angles respectively, rather than both acute angles or both obtuse angles. This ensures that the setting method of the internal angles in the fifth virtual quadrilateral matches the adjustment method of the center of gravity of the pixel emission area in the first sub-pixel, and ensures that the internal angles in the fifth virtual quadrilateral are reasonably distributed. This avoids the situation where the display difference between the non-right-angle concentrated setting area and other areas due to the non-right-angle concentrated setting is large, thereby ensuring that the overall display balance of the display panel is good.

[0149] Figure 28 is a schematic structural diagram of the eleventh first sub-pixel provided in an embodiment of the present application, Figure 29 is a schematic structural diagram of a twelfth first sub-pixel provided in an embodiment of the present application, Figure 28 Take the first sub-pixel including the first color sub-pixel 10R as an example for explanation. Figure 29 The following description is made by taking the example that the first sub-pixel includes the first color sub-pixel 10R and the second color sub-pixel 10B. Figure 28 and Figure 29 As shown, among the four inner angles with the center of gravity of the pixel emission area of the first sub-pixel as the common vertex, the opposite angles are complementary.

[0150] like Figure 28 and Figure 29As shown, the four inner angles with the center of gravity of the pixel emission area of the first sub-pixel as a common vertex can be understood as the four inner angles corresponding to the first sub-pixel in the four fifth virtual quadrilaterals 45 with the center of gravity of the pixel emission area of the first sub-pixel as a common vertex. Figure 28 and Figure 29 As shown, among the four internal angles with the center of gravity of the pixel emission area of the first sub-pixel as the common vertex, the opposite angles are complementary, that is, the sum of the angles between the opposite angles is 180°. Moreover, among the four internal angles with the center of gravity of the pixel emission area of the first sub-pixel as the common vertex, there are two acute angles and two obtuse angles, that is, among the four internal angles with the center of gravity of the pixel emission area of the first sub-pixel as the common vertex, one group of opposite angles includes one acute angle and one obtuse angle, and the other group of opposite angles also includes one acute angle and one obtuse angle that are complementary. Figure 28 As shown, the first sub-pixel, that is, the first color sub-pixel 10R, has four internal angles with the center of gravity as the common vertex. One set of opposite angles includes an acute angle and an obtuse angle, and the two angles are complementary. The other set of opposite angles also includes an acute angle and an obtuse angle, and the two angles are complementary. Figure 29 As shown, of the four interior angles of the first subpixel (i.e., first color subpixel 10R and second color subpixel 10B) with their centers of gravity serving as common vertices, one set of opposite angles includes an acute angle and an obtuse angle, both of which are complementary; the other set of opposite angles also includes an acute angle and an obtuse angle, both of which are complementary. This ensures that the acute and obtuse angles in the fifth virtual quadrilateral 45 are separated diagonally, avoiding the situation where the acute and obtuse angles are concentrated diagonally, resulting in significant display differences between the areas where the acute or obtuse angles are concentrated and other areas, thereby ensuring a well-balanced display across the entire display panel.

[0151] For further reference, Figure 28 and Figure 29 As shown, among the four internal angles with the center of gravity of the emission area of the first sub-pixel 11 as the common vertex, two obtuse angles are located on one side of the virtual line VL, and two acute angles are located on the other side of the virtual line; the pixel emission area has a first shape 20, and the first shape 20 of the first sub-pixel includes at least one first shape segment 201, and the first shape segment 201 includes a curve; the extension direction of the virtual line VL intersects with the direction in which the center of gravity of the emission area of the first sub-pixel 11 points to the first shape segment 201.

[0152] like Figure 28 and Figure 29 As shown, the extension direction of the virtual line VL here intersects with the direction in which the center of gravity of the emission area of the first sub-pixel 11 points to the first shape segment 201. Figure 28 and Figure 29The following example illustrates that the direction in which the center of gravity of the emission area of the first sub-pixel 11 points to the first shape segment 201 is the vertical direction, and the direction in which the virtual line VL extends is the horizontal direction. Of the four internal angles with the center of gravity of the emission area of the first sub-pixel as the common vertex, two obtuse angles are located on one side of the virtual line VL, and two acute angles are located on the other side of the virtual line VL, as shown in FIG. Figure 28 and Figure 29 As shown, the two obtuse angles are located above the virtual line VL, and the two acute angles are located below the virtual line VL. Reasonable setting of the angles of the four internal angles with the center of gravity of the emissive area of the first sub-pixel 11 as a common vertex can ensure that the angle setting matches the offset method of the center of gravity of the pixel emissive area in the first sub-pixel, ensuring that the angle distribution of the four internal angles with the center of gravity of the emissive area of the first sub-pixel 11 as a common vertex is reasonable.

[0153] For further reference, Figure 29 As shown, the first sub-pixel 11 includes a first color sub-pixel 10R and a second color sub-pixel 10B; the area of the pixel emission region in the first color sub-pixel 10R is smaller than the area of the pixel emission region in the second color sub-pixel 10B; the angle of the acute angle with the center of gravity of the pixel emission region in the first color sub-pixel as the vertex is greater than the angle of the acute angle with the center of gravity of the pixel emission region in the second color sub-pixel as the vertex.

[0154] Specifically, when the degree of offset of the center of gravity of the pixel emission area compared to the center of gravity of the electrode body is the same, for example, the offset is 1 / 5 of the radius of the electrode body, the larger the area of the pixel emission area, the greater the absolute offset of the center of gravity of the pixel emission area and the center of gravity of the electrode body. Therefore, when the first color sub-pixel 10R and the second color sub-pixel 10B are both first sub-pixels, when the area of the pixel emission area in the first color sub-pixel 10R is smaller than the area of the pixel emission area in the second color sub-pixel 10B, the offset of the center of gravity of the pixel emission area in the first color sub-pixel 10R compared to the center of gravity of the electrode body is smaller than the offset of the center of gravity of the pixel emission area in the second color sub-pixel 10B compared to the center of gravity of the electrode body. The smaller the offset, the smaller the change in the corresponding internal angle in the fifth virtual quadrilateral 45, that is, when the internal angle is acute or obtuse, the smaller the change from a right angle. Thus, when the area of the pixel emissive area in the first color sub-pixel 10R is smaller than the area of the pixel emissive area in the second color sub-pixel 10B, the acute angle with the center of gravity of the pixel emissive area in the first color sub-pixel as the vertex is greater than the acute angle with the center of gravity of the pixel emissive area in the second color sub-pixel as the vertex, ensuring that the angle setting method matches the center of gravity offset of the first sub-pixels of different colors, that is, matches the area of the pixel emissive area of the first sub-pixel. For example, the acute angle with the center of gravity of the pixel emissive area in the first color sub-pixel 10R as the vertex can be 89.58°, and the acute angle with the center of gravity of the pixel emissive area in the second color sub-pixel 10B as the vertex can be 89.46°.

[0155] It should be noted that Figure 29 The following example illustrates the case where the area of the pixel emissive region in the first color sub-pixel 10R is smaller than the area of the pixel emissive region in the second color sub-pixel 10B, and the acute angle with the center of gravity of the pixel emissive region in the first color sub-pixel as its vertex is greater than the acute angle with the center of gravity of the pixel emissive region in the second color sub-pixel as its vertex. It is understood that when the area of the pixel emissive region in the first color sub-pixel 10R is larger than the area of the pixel emissive region in the second color sub-pixel 10B, the acute angle with the center of gravity of the pixel emissive region in the first color sub-pixel as its vertex is smaller than the acute angle with the center of gravity of the pixel emissive region in the second color sub-pixel as its vertex.

[0156] Further, Figure 30 This is a schematic structural diagram of the first sixth virtual quadrilateral provided in an embodiment of the present application. Figure 30 As shown, the sixth virtual quadrilateral 46 comprises a regular virtual quadrilateral; the four corresponding internal angles of the sixth virtual quadrilateral 46 are all right angles.

[0157] like Figure 30As shown, the line connecting the centers of gravity of the pixel emission areas of the four third-color sub-pixels 10G forms a sixth virtual quadrilateral. The pixel emission areas of the third-color sub-pixels 10G are regularly shaped, such as circular. In this case, the center of gravity of the pixel emission areas of the third-color sub-pixels 10G coincides with the center of gravity of the electrode body. The four interior angles of the sixth virtual quadrilateral 46 are all right angles, ensuring a regular arrangement of the centers of gravity of the pixel emission areas of the four third-color sub-pixels 10G, ensuring a regular display effect of the third-color sub-pixels 10G, and thus ensuring a good display effect of the entire display panel.

[0158] Continue to refer Figure 30 As shown, the first color sub-pixel or the second color sub-pixel located in the sixth virtual quadrilateral 46 is the first sub-pixel 11 ; the center of gravity of the pixel emission area in the first sub-pixel 11 located in the sixth virtual quadrilateral 46 is staggered with the center of gravity of the sixth virtual quadrilateral 46 .

[0159] like Figure 30 As shown, the sixth virtual quadrilateral is a regular virtual quadrilateral, and the center of gravity of the sixth virtual quadrilateral 46 can be the intersection of the diagonal lines of the sixth virtual quadrilateral 46. The shape of the pixel emission area of the first sub-pixel 11 includes a first shape 20, and the first shape 20 includes a first shape segment 201. The first shape segment 201 can be understood as the portion of the first shape 20 that has not changed in shape. When the first shape 20 has not changed, the center of gravity of the pixel emission area of the first sub-pixel 11 located within the sixth virtual quadrilateral 46 coincides with the center of gravity of the sixth virtual quadrilateral without considering the error; when the first shape of the first sub-pixel 11 changes, the first shape 20 and the center of gravity of the sixth virtual quadrilateral 46 are staggered. Furthermore, the center of gravity of the pixel emission area of the first sub-pixel 11 located within the sixth virtual quadrilateral 46 can be located on the side of the center of gravity of the sixth virtual quadrilateral close to the first shape segment, ensuring that the setting position of its center of gravity matches the change mode of the first shape.

[0160] Based on the above embodiments, Figure 31 is a schematic structural diagram of the thirteenth first sub-pixel provided in an embodiment of the present application, such as Figure 31 As shown, among the multiple first sub-pixels 11 located in the same sub-pixel row, the centers of gravity of the multiple electrode main bodies 1011 are located on the same straight line; and / or, among the multiple first sub-pixels 11 located in the same sub-pixel column, the centers of gravity of the multiple electrode main bodies 1011 are located on the same straight line.

[0161] like Figure 31As shown, in the plurality of first sub-pixels 11 located in the same sub-pixel row, the centers of gravity of the plurality of electrode main bodies 1011 are located on the same straight line, and the extension direction of the straight line can be the direction of the sub-pixel row. Since the display panel also includes other signal lines, such as at least one of a scanning signal line, a light-emitting control signal line, an initialization signal line, and a power signal line extending in the direction of the sub-pixel row, setting the centers of gravity of the plurality of electrode main bodies 1011 in the plurality of first sub-pixels 11 located in the same sub-pixel row to be located on the same straight line is beneficial to the symmetrical arrangement of the signal lines extending in the direction of the sub-pixel row, and achieving regularity in the layout of the signal lines extending in the direction of the sub-pixel row.

[0162] Furthermore, the display panel may also include a light-shielding layer located on the light-emitting side of the sub-pixels. The light-shielding layer includes multiple light-shielding sections. Along the thickness of the display panel, the light-shielding sections cover the aforementioned signal lines to prevent the signal lines from reflecting ambient light and thereby interfering with the light emitted by the display panel. Regular arrangement of the signal lines also ensures the regular arrangement of the light-shielding sections. Regular arrangement of the light-shielding sections facilitates adjustment of the viewing angle and direction of light emitted by the display panel, reduces color shift in all directions of the display panel, and improves the display quality.

[0163] Similarly, in the plurality of first sub-pixels 11 located in the same sub-pixel column, the centers of gravity of the plurality of electrode main bodies 1011 are located on the same straight line, and the extension direction of the straight line can be the direction of the sub-pixel column. Since the display panel also includes other signal lines, such as at least one of a data signal line, a touch signal line, and a power signal line extending in the direction of the sub-pixel column, arranging the centers of gravity of the plurality of electrode main bodies 1011 in the plurality of first sub-pixels 11 located in the same sub-pixel column to be located on the same straight line is beneficial to the symmetric arrangement of the signal lines extending in the direction of the sub-pixel column, thereby achieving a regular layout of the signal lines extending in the direction of the sub-pixel column.

[0164] Furthermore, the display panel may also include a light-shielding layer located on the light-emitting side of the sub-pixels. The light-shielding layer includes multiple light-shielding sections. Along the thickness of the display panel, the light-shielding sections cover the aforementioned signal lines to prevent the signal lines from reflecting ambient light and thereby interfering with the light emitted by the display panel. Regular arrangement of the signal lines also ensures the regular arrangement of the light-shielding sections. Regular arrangement of the light-shielding sections facilitates adjustment of the viewing angle and direction of light emitted by the display panel, reduces color shift in all directions of the display panel, and improves the display quality.

[0165] On the basis of the above embodiments, continue to refer to Figure 31As shown, the multiple sub-pixels also include multiple third sub-pixels 13, the center of gravity of the electrode main body 1011 in the third sub-pixel coincides with the center of gravity of the pixel emission area 102; in the multiple third sub-pixels 13 located in the same sub-pixel row, the centers of gravity of the multiple electrode main bodies 1011 are located on the same straight line; and / or, in the multiple third sub-pixels 13 located in the same sub-pixel column, the centers of gravity of the multiple electrode main bodies 1011 are located on the same straight line.

[0166] like Figure 31 As shown, the third sub-pixel 13 is a sub-pixel in which the center of gravity of the electrode main body 1011 coincides with the center of gravity of the pixel emission area 102, or it can be understood that the third sub-pixel is a sub-pixel in which the shape of the pixel emission area does not change. The third sub-pixel 13 may include the second sub-pixel mentioned in the above embodiment.

[0167] Further, such as Figure 31 As shown, in the plurality of third sub-pixels 13 located in the same sub-pixel row, the centers of gravity of the plurality of electrode main bodies 1011 are located on the same straight line, and the extension direction of the straight line can be the direction of the sub-pixel row. Since the display panel also includes other signal lines, such as at least one of a scanning signal line, a light-emitting control signal line, an initialization signal line, and a power supply signal line extending in the direction of the sub-pixel row. Setting the centers of gravity of the plurality of electrode main bodies 1011 in the plurality of third sub-pixels 13 located in the same sub-pixel row to be located on the same straight line is beneficial to the symmetrical setting of the signal lines extending in the direction of the sub-pixel row, and realizing the regularity of the layout of the signal lines extending in the direction of the sub-pixel row. Furthermore, the display panel may also include a light-shielding layer located on the light-emitting side of the sub-pixel, the light-shielding layer including a plurality of light-shielding sections, and the light-shielding sections covering the above-mentioned signal lines along the thickness direction of the display panel to prevent the signal lines from reflecting ambient light and thereby interfering with the light output of the display panel. The regular setting of the signal lines can also ensure the regular setting of the shading divisions. The regularly set shading divisions are conducive to adjusting the light output angle and direction of the display panel, which is conducive to reducing the problem of color deviation in all directions of the display panel and improving the display effect.

[0168] Similarly, in the plurality of third sub-pixels 13 located in the same sub-pixel column, the centers of gravity of the plurality of electrode main bodies 1011 are located on the same straight line, and the extension direction of the straight line can be the direction of the sub-pixel column. Since the display panel also includes other signal lines, such as at least one of a data signal line, a touch signal line, and a power signal line extending in the direction of the sub-pixel column. Setting the centers of gravity of the plurality of electrode main bodies 1011 in the plurality of third sub-pixels 13 located in the same sub-pixel column to be located on the same straight line is beneficial to the symmetrical setting of the signal lines extending in the direction of the sub-pixel column, and realizing the regularity of the layout of the signal lines extending in the direction of the sub-pixel column. Furthermore, the display panel may also include a light-shielding layer located on the light-emitting side of the sub-pixel, the light-shielding layer including a plurality of light-shielding sections, and the light-shielding sections covering the above-mentioned signal lines along the thickness direction of the display panel to prevent the signal lines from reflecting ambient light and thereby interfering with the light output of the display panel. The regular setting of the signal lines can also ensure the regular setting of the shading divisions. The regularly set shading divisions are conducive to adjusting the light output angle and direction of the display panel, which is conducive to reducing the problem of color deviation in all directions of the display panel and improving the display effect.

[0169] Continue to refer Figure 31 As shown, the multiple sub-pixels also include multiple third sub-pixels 13, and the center of gravity of the electrode main body in the third sub-pixel 13 coincides with the center of gravity of the pixel emission area; in the multiple first sub-pixels 11 and the multiple third sub-pixels 13 located in the same sub-pixel row, the centers of gravity of the multiple electrode main bodies are located on the same straight line; and / or, in the multiple first sub-pixels 11 and the multiple third sub-pixels 13 located in the same sub-pixel column, the centers of gravity of the multiple electrode main bodies are located on the same straight line.

[0170] like Figure 31 As shown, in the multiple first sub-pixels 11 and the multiple third sub-pixels 13 located in the same sub-pixel row, the centers of gravity of the multiple electrode main bodies are located on the same straight line. This further simplifies the routing of signal lines extending along the extension direction of the sub-pixel row and increases the convenience of setting up the light-shielding section. The same light-shielding section can simultaneously cover multiple signal lines, reducing the difficulty of manufacturing the light-shielding section. Similarly, in the multiple first sub-pixels 11 and the multiple third sub-pixels 13 located in the same sub-pixel column, the centers of gravity of the multiple electrode main bodies are located on the same straight line. This also further simplifies the routing of signal lines extending along the extension direction of the sub-pixel row and increases the convenience of setting up the light-shielding section. The same light-shielding section can simultaneously cover multiple signal lines, reducing the difficulty of manufacturing the light-shielding section.

[0171] Based on the above embodiments, Figure 32 yes Figure 2 The second cross-sectional structure diagram of the first sub-pixel along the cross-sectional line AA' is provided, combined with Figure 32As shown, the display panel further includes a color resist structure 107 located on the light-emitting side of the sub-pixel. The color resist structure 107 includes a plurality of color resist units 1071. Along the thickness direction of the display panel (the Z direction shown in the figure), the color resist units 1071 overlap with the sub-pixels.

[0172] like Figure 32 As shown, the display panel also includes an encapsulation structure 106 and a color resist structure 107 located on the light-emitting side of the sub-pixel. The encapsulation structure 106 can prevent water vapor or oxygen from entering the sub-pixel, ensuring that the sub-pixel has good performance. Furthermore, the encapsulation structure 106 can include a single-layer encapsulation layer or a multi-layer encapsulation layer (not shown in the figure). For example, the encapsulation structure 106 can include an inorganic encapsulation layer-organic encapsulation layer and a stacked structure of inorganic encapsulation layers. The inorganic encapsulation layer can support and protect the sub-pixel, and the organic encapsulation layer can absorb water vapor or oxygen to ensure that the sub-pixel is protected from water and oxygen corrosion. Furthermore, the color resist structure 107 is located on the side of the encapsulation layer 106 away from the sub-pixel. The color resist structure 107 may include a plurality of color resist units 1071. Along the thickness direction of the display panel (the Z direction shown in the figure), the color resist unit 1071 overlaps with the sub-pixel. The color resist unit 1071 can modulate the light emitted by the sub-pixel so that light with the same color as the color resist unit 1071 is emitted and light with a different color from the color resist unit 1071 is absorbed. For example, when the light emitted by the sub-pixel is colored light, the setting of the color resist unit 1071 can increase the color purity and ensure the display effect of the display panel; when the light emitted by the sub-pixel is white light, the color resist unit 1071 can filter the light of the same color and then emit it, and filter and absorb the light of different colors, thereby achieving the color display effect of the display panel. In addition, the setting of the color resist structure 107 can also reduce the interference of external ambient light on the light emitted by the display panel. For example, when the light entering the display panel through the color resist unit 1071 is reflected inside the display panel, only the light of the same color as the color resist unit 1071 can be emitted, and the light of different colors from the color resist unit 1071 will be absorbed by the color resist unit 1071, thereby reducing the re-emission of the external ambient light reflected after entering the display panel, reducing the interference of the external ambient light on the display light, and improving the display contrast.

[0173] Continue to refer Figure 32As shown, the display panel also includes a light-shielding layer 108. The light-shielding layer 108 may include a plurality of light-shielding sub-sections 1081. The light-shielding sub-sections 1081 cover the areas not covered by the color-resistance units 1071 in the display panel. That is, the setting of the light-shielding layer 108 will not affect the normal light output of the sub-pixels, but can absorb the large viewing angle light of the sub-pixels to avoid large viewing angle color deviation. At the same time, the setting of the light-shielding layer 108 can also block the metal traces in the display panel to avoid the problem of visible metal traces on the display panel. In addition, the light-shielding layer 108 can also absorb the external ambient light reflected inside the display panel, further reducing the interference of the external ambient light on the display light.

[0174] On the basis of the above embodiments, continue to refer to Figure 31 As shown, the multiple sub-pixels also include multiple third sub-pixels 13, the center of gravity of the electrode main body 1011 in the third sub-pixel 3 coincides with the center of gravity of the pixel emission area 102; the pixel emission area 102 has a first shape 20; the first shape 20 in the third sub-pixel 13 is circular.

[0175] like Figure 31 As shown, the first shape 20 in the third sub-pixel 13 is circular, and the pixel emission area 102 of the third sub-pixel 13 has a regular shape, ensuring good light emission effect. In addition, the circular shape of the first shape 20 can avoid optical diffraction problems and further improve the display effect of the display panel.

[0176] In summary, the display panel provided by the embodiment of the present application realizes a scheme in which the center of gravity of the pixel emission area in the first sub-pixel and the center of gravity of the electrode main body are staggered by adjusting the first shape of the first sub-pixel, thereby reducing the difficulty of aligning the pixel emission area with the electrode main body and reducing the difficulty of the manufacturing process of the display panel. Furthermore, by reasonably setting the degree of offset of the center of gravity of the pixel emission area in the first sub-pixel, on the one hand, it is ensured that the light-emitting area of the first sub-pixel is less affected, and the normal light-emitting area and light-emitting brightness of the first sub-pixel are ensured; on the other hand, by reasonably setting the degree of offset of the center of gravity of the pixel emission area in the first sub-pixel, it is ensured that the distance between the first sub-pixel and the first sub-pixel and between the first sub-pixel and other sub-pixels is appropriate, ensuring that the display effect of the display panel is well balanced, and at the same time, the restrictions on other structural positions and processes are relatively small, thereby improving the position of other structures and the degree of freedom of process, further ensuring that the overall structural uniformity of the display panel is good and the process difficulty is relatively low.

[0177] Based on the same application concept, the present application embodiment also provides a display panel, continue to refer to Figure 1 、 Figure 2As shown in the figure, the display panel provided by the embodiment of the present application includes a plurality of sub-pixels 10, the sub-pixel 10 includes a pixel emission area / 12, the pixel emission area 102 has a first shape 20; the sub-pixel 10 includes a first sub-pixel 11, the first shape of the first sub-pixel 11 includes a first shape segment 201 and a second shape segment 202 connected, at least the first shape segment 201 includes a curve, and the curvature of at least some of the line segments in the second shape segment 202 is different from the curvature of the first shape segment 201; the first shape segment 01 and the second shape segment 202 are connected. The connection points of 202 include a first connection point P1 and a second connection point P2. The connection line between the first connection point P1 and the center O' of the virtual circle where the first shape segment 201 is located is the second connection line P1O', and the connection line between the second connection point P2 and the center O' of the virtual circle is the third connection line P2O'; the angle between the second connection line P1O' and the third connection line P2O' toward the side of the first shape segment 201 is θ1, and the angle between the second connection line P1O' and the third connection line P2O' toward the side of the second shape segment 202 is θ2; wherein, θ1>θ2.

[0178] like Figure 1 、 Figure 2 and Figure 4 As shown, Figure 1 As shown, the display panel includes a plurality of sub-pixels 10, and the plurality of sub-pixels 10 include sub-pixels with different luminous colors, such as a first color sub-pixel, a second color sub-pixel, and a third color sub-pixel. The luminous colors of the first color sub-pixel, the second color sub-pixel, and the third color sub-pixel are different to achieve color display of the display panel.

[0179] refer to Figure 1 and Figure 2 As shown, the sub-pixel 10 may include a first electrode 101, a light-emitting layer 103, a second electrode 104 and a pixel circuit 105. The first electrode 101 may be the anode of the sub-pixel, and the second electrode 104 may be the cathode of the sub-pixel. The first electrode 101 is electrically connected to the pixel circuit 105, and is used to receive the anode signal provided by the pixel circuit 105; the second electrode 104 is used to receive the cathode signal provided by the power signal line. The light-emitting layer 103 is arranged between the first electrode 101 and the second electrode 104, and is used to emit light under the action of the anode signal and the cathode signal. The pixel circuit 105 may include transistors or capacitors, and the pixel circuit 105 may include different numbers of transistors and / or capacitors according to different setting areas. For example, the pixel circuit 105 may include two transistors and one capacitor to form a pixel circuit with a "2T1C" structure (T represents transistor, C represents capacitor); or the pixel circuit 105 may include seven transistors and one capacitor to form a pixel circuit with a "7T1C" structure. The embodiment of the present application does not limit the specific setting method of the pixel circuit 105. Figure 31 and a transistor exemplarily represent the pixel circuit 105 .

[0180] The pixel emission region 102 can be understood as the light emitting region of the sub-pixel 10, which corresponds to the pixel opening in the sub-pixel 10, for example Figure 3 In the area corresponding to the opening structure in the pixel defining layer (PDL), the light-emitting layer 103 is formed at least in the pixel emission area 102. The pixel emission area 102 has a first shape 20, and the first shape 20 of the first sub-pixel 11 includes at least one first shape segment 201 and at least one second shape segment 202. The first shape segment 201 and the second shape segment 202 can be understood as two shapes with different curvatures. Among them, at least the first shape segment 202 includes a curve, for example, the first shape segment 201 can include an arc curve, and the dotted line shown in the figure is the trajectory of the virtual circle where the first shape segment 201 is located when the first shape segment 201 is an arc curve. The second shape segment 202 can include a curve, and the curvature of different positions in the same second shape segment can be different.

[0181] Further, such as Figure 4As shown, the connection points of the first shape segment 201 and the second shape segment 202 include a first connection point P1 and a second connection point P2, the connection line between the first connection point and the center O' of the virtual circle where the first shape segment 201 is located is the second connection line P1O', and the connection line between the second connection point P2 and the center O' of the virtual circle is the third connection line P2O'; the angle θ1 between the second connection line P1O' and the third connection line P2O' toward the side of the first shape segment 201 is equal to the angle θ2 between the second connection line P1O' and the third connection line P2O' toward the side of the second shape segment. The condition θ1>θ2 is satisfied, that is, the angle between the second line P1O' and the third line P2O' toward the first shape segment 201 is greater than the angle between the second line P1O' and the third line P2O' toward the second shape segment. That is, for the pixel emission area 20, the arc center angle corresponding to the part that has not undergone shape change, that is, the first shape segment 201, is greater than the arc center angle corresponding to the part that has undergone shape change, that is, the second shape segment 202. That is, the proportion of the arc center angle of the part of the entire pixel emission area that has undergone shape change is not large. In this way, the overall deformation of the pixel emission area 102 can be ensured to be small, and the normal luminous shape of the first sub-pixel has little effect, thereby ensuring the normal luminescence of the first sub-pixel. In addition, by adjusting the shape of the second shape segment 201 to achieve the adjustment of the center of gravity of the pixel emission area 102, the adjustment of the center of gravity of the pixel emission area 102 can achieve a more balanced distribution of the center of gravity of the pixel emission areas 102 of the multiple first sub-pixels 11, thereby ensuring a more balanced display effect of the multiple first sub-pixels, thereby further improving the display effect of the display panel. Moreover, the adjustment of the center of gravity of the pixel emission area 102 can adjust the distance between the first sub-pixel 11 and the other adjacent sub-pixels, thereby ensuring that the distance between the first sub-pixel 11 and the other sub-pixels is more balanced, thereby ensuring the uniformity of the leakage current between the first sub-pixel 11 and the other sub-pixels, and improving the display effect; and, when the distance between the first sub-pixel 11 and the other sub-pixels is more balanced, it can also reduce the position of the structure set between the sub-pixels and the process restrictions, thereby increasing the difficulty of the overall process of the display panel and improving the production efficiency of the display panel.

[0182] In summary, the display panel provided by the embodiment of the present application adjusts the center of gravity of the pixel emission area in the first sub-pixel by adjusting the first shape of the first sub-pixel. The adjustment of the center of gravity of the pixel emission area can achieve a more balanced distribution of the center of gravity of the pixel emission areas of multiple first sub-pixels, ensuring a more balanced display effect for the multiple first sub-pixels. In addition, the adjustment of the center of gravity of the pixel emission area can adjust the spacing between the first sub-pixel and the adjacent sub-pixels, ensuring a more balanced spacing between the first sub-pixel and the other sub-pixels, ensuring the uniformity of the leakage current between the first sub-pixel and the other sub-pixels, and improving the display effect. In addition, when the spacing between the first sub-pixel and the other sub-pixels is more balanced, the position and process restrictions of the structure set between the sub-pixels can be reduced, thereby improving the difficulty of the overall process of the display panel and improving the efficiency of the display panel manufacturing. Furthermore, the first shape corresponding to the pixel emission area in the first sub-pixel has an arc center angle corresponding to the portion where the shape is changed is smaller than the portion where the shape is not changed. In this way, the overall deformation of the pixel emission area can be ensured to be small, which has little impact on the normal light-emitting shape of the first sub-pixel, and ensures normal light emission of the first sub-pixel.

[0183] On the basis of the above embodiments, continue to refer to Figure 1 、 Figure 2 and Figure 4 As shown, 120°≤θ2<180°, for example, θ2 can be 120°, 123°, 128°, 132°, 135°, 140°, 148°, 149°, 154°, 158°, 160°, 165°, 170°, 172°, 175° or 178°. The embodiment of the present application does not limit the data value of θ2. By reasonably setting the numerical range of θ2, the roundness of the pixel emission area in the first sub-pixel can be further guaranteed, and the light diffraction problem and color deviation problem of the first sub-pixel will not be caused, thereby ensuring the light-emitting effect of the first sub-pixel.

[0184] Furthermore, 130°≤θ2≤150°, and furthermore, θ2=140°. In this way, the roundness of the pixel emission area in the first sub-pixel is fully guaranteed, thereby ensuring the luminous effect of the first sub-pixel.

[0185] On the basis of the above embodiments, continue to refer to Figure 10 As shown, the line between the first connection point P1 and the second connection point P2 is the first line P1P2; the first point P3 on the first shape segment 201 has a maximum vertical distance from the first line P1P2, and the second point P4 on the second shape segment has a maximum vertical distance from the first line P1P2; the length of the line between the first point P3 and the center O' of the virtual circle where the first shape segment 201 is located is R1, and the length of the line between the second point and the center of the virtual circle where the first shape segment is located is R2; wherein, R1>R2.

[0186] like Figure 10 As shown, the third point P3 can be understood as the point on the first shape segment 201 with the greatest distance from the first connecting line P1P2, and the fourth point P4 can be understood as the point on the second shape segment 202 with the greatest distance from the first connecting line P1P2. The length R1 of the line between the first point P3 and the center point O' of the virtual circle containing the first shape segment 201 and the length R2 of the line between the second point P3 and the center point of the virtual circle containing the first shape segment satisfy R1>R2. That is, the point P3 on the first shape segment 201 with the greatest distance from the first connecting line P1P2 is closer to the center point O' of the virtual circle containing the first shape segment 201 than the point P4 on the second shape segment 202 with the greatest distance from the first connecting line P1P2. In other words, compared to the virtual curve 30, the second shape segment 202 is offset as a whole toward the side close to the first shape segment 201, ensuring that the center of gravity of the pixel emission area 102 can be adjusted, further achieving a more balanced distribution of the center of gravity of the pixel emission areas 102 of the multiple first sub-pixels 11, and ensuring a more balanced display effect for the multiple first sub-pixels. In addition, the adjustment of the center of gravity of the pixel emission area 102 can adjust the spacing between the first sub-pixel 11 and the remaining adjacent sub-pixels, ensuring a more balanced spacing between the first sub-pixel 11 and the other sub-pixels, ensuring the uniformity of the leakage current between the first sub-pixel 11 and the other sub-pixels, and improving the display effect; and when the spacing between the first sub-pixel 11 and the other sub-pixels is more balanced, it can also reduce the position of the structure set between the sub-pixels and the process restrictions, thereby increasing the difficulty of the overall process of the display panel and improving the efficiency of display panel preparation.

[0187] It should be noted that Figure 10 Only a feasible first shape structure is used as an example for illustration. It can be understood that Figure 4 、 Figure 6 as well as Figure 9 The structure of the first shape shown is also applicable to the solution where the length of the line between the first point and the center of the virtual circle where the first shape segment is located is greater than the length of the line between the second point and the center of the virtual circle where the first shape segment is located, which will not be repeated here.

[0188] Furthermore, 0.75≤R2 / R1≤0.95, that is, the ratio between R2 and R1 is between 0.75-0.95. For example, R2 / R1 can be 0.75, 0.78, 0.80, 0.83, 0.85, 0.88, 0.90, 0.92 or 0.95. The embodiment of the present application does not limit the data value of R2 / R1. The ratio of R2 / R1 can limit the degree of deviation of the second shape segment 202 compared with the virtual curve 30, and can also limit the area of the pixel emission area and the roundness of the first shape. Setting 0.75≤R2 / R1≤0.95, that is, the degree of deviation of the second shape segment 202 compared with the virtual curve 30 is not too large, which can ensure that the degree of reduction in the area of the pixel emission area is not too large, and the roundness of the first shape does not change much, which will not affect the light emitting effect of the first sub-pixel, will not cause the light diffraction problem and color deviation problem of the first sub-pixel, and ensure the light emitting effect of the first sub-pixel.

[0189] Furthermore, 0.85<R2 / R1≤0.95, and even further, R2 / R1=0.9. In this way, the luminous area and roundness of the pixel emission region in the first sub-pixel are fully guaranteed, thereby ensuring the luminous effect of the first sub-pixel.

[0190] For further reference, Figure 1 、 Figure 2 、 Figure 4 and Figure 10 As shown, the sub-pixel 10 also includes a first electrode 101, which includes a connected electrode main body 1011 and an electrode connecting part 1012, and the electrode main body 1011 overlaps with the pixel emission area 102; the center of gravity of the electrode main body 1011 in the first sub-pixel 11 is staggered with the center of gravity of the pixel emission area 102.

[0191] The first electrode 101 includes an electrode main body 1011 and an electrode connecting portion 1012. The electrode main body 1011 is the main structure of the first electrode 101 and is generally a relatively regular shape, for example Figure 1 and Figure 2 The electrode connecting portion 1012 is a connecting structure between the electrode main body 1011 and the pixel circuit 103. As an auxiliary connecting portion of the first electrode 101, its area is generally small, for example, much smaller than the area of the electrode main body 1011, and its shape can be as follows: Figure 1 and Figure 2 The shape shown is similar to a "little tail".

[0192] In a conventional sub-pixel structure, it is necessary to set the center of gravity of the pixel emission area to coincide with the center of gravity of the electrode main body. This results in a strict preparation process for the pixel opening, and a strict alignment process is required to ensure that the center of gravity of the pixel emission area coincides with the center of gravity of the electrode main body. In an embodiment of the present application, a plurality of sub-pixels 10 are provided, including a first sub-pixel 11. The first sub-pixel 11 is a sub-pixel 10 having a different luminous color than one or at least two of the sub-pixels 10. In the first sub-pixel 11, the center of gravity O' of the electrode main body 1011 is staggered with the center of gravity O of the pixel emission area 102, that is, along the light emitting direction of the display panel or the thickness direction of the display panel, the center of gravity O' of the electrode main body 1011 does not coincide with the center of gravity O of the pixel emission area 102. This can reduce the difficulty of aligning the pixel emission area 102 with the electrode main body 1011, reduce the process difficulty of preparing the pixel opening in the pixel defining layer, thereby reducing the difficulty of preparing the display panel and improving the preparation efficiency of the display panel.

[0194] like Figure 1 and Figure 13 As shown, the display panel provided in the embodiment of the present application further includes a plurality of first sub-pixel groups 31. The first sub-pixel group 31 includes a first first sub-pixel 111, a second first sub-pixel 112, a third first sub-pixel 113, a fourth first sub-pixel 114, and a fifth first sub-pixel 115, which emit the same luminous color. The first first sub-pixel 111 and the second first sub-pixel 112 are located in the same sub-pixel row and are the two closest first sub-pixels of the same color; the third first sub-pixel 113 and the fourth first sub-pixel 114 are located in the same sub-pixel row and are the two closest first sub-pixels of the same color; and the fifth first sub-pixel 115 is located in a sub-pixel row. Furthermore, the pixel row where the first first sub-pixel 111 is located, the pixel row where the fifth first sub-pixel 115 is located, and the pixel row where the third first pixel 113 is located are the three sub-pixel rows that contain first sub-pixels and are closest to each other. Furthermore, the first first sub-pixel 111, the second first sub-pixel 112, the third first sub-pixel 113, and the fourth first sub-pixel 114 form a first virtual quadrilateral 41. The centers of gravity of the first first sub-pixel 111, the second first sub-pixel 112, the third first sub-pixel 113, and the fourth first sub-pixel 114 are respectively located at the four vertices of the first virtual quadrilateral 41, and the fifth first sub-pixel 115 is located inside the first virtual quadrilateral 41.

For example, the fourth line O 11 O 15 、The fifth line O 12 O15 、The sixth line O 13 O 15 And the seventh line O 14 O 15 The length of the fourth line O is roughly the same. 11 O 15 、The fifth line O 12 O 15 、The sixth line O 13 O 15 And the seventh line O 14 O 15 The ratio of any connecting line to the other connecting lines is between 0.8 and 1.2. This ensures that the centers of gravity of the five first sub-pixels corresponding to the first sub-pixel group 31 are evenly distributed, thereby facilitating display uniformity of the first sub-pixels and further achieving display uniformity of the entire display panel.

[0195] Based on the above embodiment, the fourth line O 11 O 15 、The fifth line O 12 O 15 、The sixth line O 13 O 15 And the seventh line O 14 O 15 The maximum length is L1 and the minimum length is L2; wherein, (L1-L2) / L1≤5%.

[0196] In other words, the maximum length L1 and the minimum length L2 of the four lines satisfy (L1-L2) / L1≤5%, meaning the maximum length difference of the four lines is within 5%. This further ensures that the centers of gravity of the five first sub-pixels in the first sub-pixel group 31 are evenly distributed, further improving the display uniformity of the first sub-pixels and the display uniformity of the entire display panel.

[0197] On the basis of the above embodiments, continue to refer to Figure 1 and Figure 14As shown, the display panel also includes a plurality of second sub-pixel groups 32, the second sub-pixel group 32 includes a plurality of second sub-pixels 12 with the same luminous color, and the center of gravity O' of the electrode main body of the second sub-pixel 12 coincides with the center of gravity of the pixel emission area O; the plurality of second sub-pixels 12 include a first second sub-pixel 121, a second second sub-pixel 122, a third second sub-pixel 123, a fourth second sub-pixel 124 and a fifth second sub-pixel 125; the first second sub-pixel 121, the second second sub-pixel 122, the third second sub-pixel 123 and the fourth second sub-pixel 124 constitute a second virtual quadrilateral 42, the centers of gravity of the first second sub-pixel 121, the second second sub-pixel 122, the third second sub-pixel 123 and the fourth second sub-pixel 124 are respectively located at the four vertices of the second virtual quadrilateral 42, and the fifth second sub-pixel 125 is located inside the second virtual quadrilateral 42; the center of gravity O of the pixel emission area of the fifth second sub-pixel 125 25 and the center of gravity O of the pixel emission area of the first and second sub-pixels 121 21 The line between them is the tenth line O 21 O 25 , the center of gravity O of the pixel emission area of the fifth second sub-pixel 125 25 and the center of gravity O of the pixel emission area of the second sub-pixel 122 22 The line between them is the eleventh line O 22 O 25 , the center of gravity O of the pixel emission area of the fifth second sub-pixel 125 25 and the center of gravity O of the pixel emission area of the third second sub-pixel 123 23 The line between them is the twelfth line O 23 O 25 , the center of gravity O of the pixel emission area of the fifth second sub-pixel 125 25 and the center of gravity O of the pixel emission area of the fourth second sub-pixel 124 24 The line between them is the thirteenth line O 24 O 25 ; The tenth line O 21 O 25 、Eleventh Connection O 22 O 25 , the twelfth line O 23 O 25 And the thirteenth connection O 24 O 25 The maximum length is L3 and the minimum length is L4; wherein, (L3-L4) / L3≤5%.

[0198] like Figure 1 and Figure 14As shown, the display panel provided in the embodiment of the present application further includes a plurality of second subpixel groups 32. The second subpixel group 32 includes a first second subpixel 121, a second second subpixel 122, a third second subpixel 123, a fourth second subpixel 124, and a fifth second subpixel 125, each emitting the same color. The first second subpixel 121 is located in a subpixel row; the second second subpixel 122, the fifth second subpixel 125, and the third second subpixel 123 are located in the same subpixel row, and the second second subpixel 122, the fifth second subpixel 125, and the third second subpixel 123 are the three closest second subpixels of the same color in the same subpixel row; the fourth second subpixel 124 is located in a subpixel row; and the subpixel row where the first second subpixel 121, the subpixel row where the second second subpixel 122, the fifth second subpixel 125, and the third second subpixel 123 are located, and the subpixel row where the fourth second subpixel 124 is located are the three subpixel rows containing second subpixels and being closest to each other. Furthermore, the first second sub-pixel 121, the second second sub-pixel 122, the third second sub-pixel 123, and the fourth second sub-pixel 124 form a second virtual quadrilateral 42. The centers of gravity of the first second sub-pixel 121, the second second sub-pixel 122, the third second sub-pixel 123, and the fourth second sub-pixel 124 are respectively located at the four vertices of the second virtual quadrilateral 42, and the fifth second sub-pixel 125 is located inside the second virtual quadrilateral 42. In addition, the center of gravity of the pixel emission area of the fifth second sub-pixel 125 is O 25 The lines connecting the four vertices of the second virtual quadrilateral 42 are the tenth line O 21 O 25 、Eleventh Connection O 22 O 25 , the twelfth line O 23 O 25 and the thirteenth line O 24 O 25 The lengths of the four lines are roughly the same, that is, the lengths of the four lines are the same or similar. For example, the tenth line O 21 O 25 、Eleventh Connection O 22 O 25 , the twelfth line O 23 O 25 and the thirteenth line O 24 O 25 The length of the tenth line O is roughly the same. 21 O 25 、Eleventh Connection O 22 O 25 , the twelfth line O 23 O 25 and the thirteenth line O 24 O 25The ratio of any connecting line to the other connecting lines is between 0.8 and 1.2. This ensures that the centers of gravity of the five second sub-pixels corresponding to the second sub-pixel group 32 are evenly distributed, thereby facilitating display uniformity of the second sub-pixels and further achieving display uniformity of the entire display panel.

[0199] Furthermore, the tenth line O 21 O 25 、Eleventh Connection O 22 O 25 , the twelfth line O 23 O 25 and the thirteenth line O 24 O 25 The maximum length L3 and the minimum length L4 satisfy (L3-L4) / L3≤5%, meaning the maximum length difference of the four connecting lines is within 5%. This further ensures that the centers of gravity of the five second sub-pixels in the second sub-pixel group 32 are evenly distributed, further improving the display uniformity of the second sub-pixels and the display uniformity of the entire display panel.

That is, the length of the line between the center of gravity of the first sub-pixel located in the first virtual quadrilateral 41 and the vertex of the first virtual quadrilateral 41 is the same as or similar to the length of the line between the center of gravity of the second sub-pixel located in the second virtual quadrilateral 42 and the vertex of the second virtual quadrilateral 42. For example, the ratio of the length of any line between the center of gravity of the first sub-pixel located in the first virtual quadrilateral 41 and the vertex of the first virtual quadrilateral 41 to the length of any line between the center of gravity of the second sub-pixel located in the second virtual quadrilateral 42 and the vertex of the second virtual quadrilateral 42 is between 0.8 and 1.2. In this way, under the premise of ensuring that multiple first sub-pixels and multiple second sub-pixels are evenly distributed and the display uniformity is good, the color mixing effect of sub-pixels of different colors is guaranteed to be good, and the color display effect of the display panel is guaranteed to be good.

[0201] On the basis of the above embodiments, continue to refer to Figure 15 and Figure 16 As shown, the display panel also includes a plurality of third sub-pixel groups 33, the third sub-pixel group 33 includes a plurality of first sub-pixels of the same luminous color, the plurality of first sub-pixels include a sixth first sub-pixel 116, a seventh first sub-pixel 117, an eighth first sub-pixel 118 and a ninth first sub-pixel 119; the sixth first sub-pixel 116, the seventh first sub-pixel 117, the eighth first sub-pixel 118 and the ninth first sub-pixel 119 constitute a third virtual quadrilateral 43, the centers of gravity of the sixth first sub-pixel 116, the seventh first sub-pixel 117, the eighth first sub-pixel 118 and the ninth first sub-pixel 119 are respectively located at the four vertices of the third virtual quadrilateral 43; the pixel emission area has a first shape 20, the first shape 20 of the first sub-pixel includes at least one first shape segment 201, and the first shape segment 201 includes a curve; in the sixth first sub-pixel 116, the center of gravity O of the pixel emission area 16 The direction pointing to the first shape segment 201 is the first direction (the X1 direction shown in the figure); in the seventh first sub-pixel 117, the center of gravity of the pixel emission area O 17 The direction pointing to the first shape segment 201 is the second direction (the X2 direction shown in the figure); in the eighth first sub-pixel 118, the center of gravity of the pixel emission area O 18 The direction pointing to the first shape segment 201 is the third direction (the X3 direction shown in the figure); in the ninth first sub-pixel 119, the center of gravity of the pixel emission area O 19 The direction pointing to the first shape segment 201 is the fourth direction (the X4 direction as shown in the figure); wherein, the sixth first sub-pixel 116, the seventh first sub-pixel 117, the eighth first sub-pixel 118 and the ninth first sub-pixel 119 are arranged along the first clockwise direction, and the second direction is rotated 90° along the first clockwise direction relative to the first direction, the third direction is rotated 90° along the first clockwise direction relative to the second direction, and the fourth direction is rotated 90° along the first clockwise direction relative to the third direction.

[0202] like Figure 15 and Figure 16As shown, the display panel includes a plurality of third subpixel groups 33, and the third subpixel group 33 includes a sixth first subpixel 116, a seventh first subpixel 117, an eighth first subpixel 118, and a ninth first subpixel 119, which emit the same luminous color. The sixth first subpixel 116 is located in a subpixel row; the seventh first subpixel 117 and the ninth first subpixel 119 are located in the same subpixel row, and the seventh first subpixel 117 and the ninth first subpixel 119 are the two closest first subpixels of the same color in the same subpixel row; the eighth first subpixel 118 is located in a subpixel row; and the subpixel row where the sixth first subpixel 116 is located, the subpixel row where the seventh first subpixel 117 and the ninth first subpixel 119 are located, and the subpixel row where the eighth first subpixel 118 is located are the three subpixel rows that contain first subpixels and are closest to each other. Furthermore, the sixth first sub-pixel 116, the seventh first sub-pixel 117, the eighth first sub-pixel 118, and the ninth first sub-pixel 119 form a third virtual quadrilateral 43, and the centers of gravity of the sixth first sub-pixel 116, the seventh first sub-pixel 117, the eighth first sub-pixel 118, and the ninth first sub-pixel 119 are respectively located at the four vertices of the third virtual quadrilateral 43. Furthermore, for the sixth first sub-pixel 116, the center of gravity of its pixel emission area O 16 The direction pointing to the first shape segment 201 is the first direction X1; for the seventh first sub-pixel 117, the center of gravity of its pixel emission area O 17 The direction pointing to the first shape segment 201 is the second direction X2; for the eighth first sub-pixel 118, the center of gravity of its pixel emission area O 18 The direction pointing to the first shape segment 201 is the third direction X3; for the ninth first sub-pixel 119, the center of gravity of its pixel emission area O 19 The direction pointing to the first shape segment 201 is the fourth direction X4; in the embodiment of the present application, the direction in which the center of gravity of the pixel emission area points to the first shape segment can also be understood as the protruding direction of the first shape segment relative to the center of gravity of the pixel emission area. In the embodiment of the present application, the first direction X1, the second direction X2, the third direction X3 and the fourth direction X4 are different. Figure 16 For example, the first direction X1, the second direction X2, the third direction X3 and the fourth direction X4 are distributed in the four directions of up, down, left and right, which is beneficial to avoid the four-directional color deviation of the display panel and improve the display effect of the display panel.

[0203] For further reference, Figure 15 and Figure 16 As shown, the sixth first sub-pixel 116, the seventh first sub-pixel 117, the eighth first sub-pixel 118 and the ninth first sub-pixel 119 are arranged along a first clockwise direction, where the first clockwise direction may be a clockwise direction or a counterclockwise direction. Figure 16Taking the first clockwise direction as an example, when the sixth first sub-pixel 116, the seventh first sub-pixel 117, the eighth first sub-pixel 118, and the ninth first sub-pixel 119 are arranged along the first clockwise direction, the first direction X1, the second direction X2, the third direction X3, and the fourth direction X4 are also arranged along the first clockwise direction. That is, the second direction X2 is rotated 90° along the first clockwise direction relative to the first direction X1, the third direction X3 is rotated 90° along the first clockwise direction relative to the second direction X2, and the fourth direction X4 is rotated 90° along the first clockwise direction relative to the third direction X3. This ensures that the centers of gravity of the sixth first sub-pixel 116, the seventh first sub-pixel 117, the eighth first sub-pixel 118, and the ninth first sub-pixel 119 are uniformly distributed, thereby preventing color shift in all four directions of the display panel and improving the display quality of the display panel.

[0204] On the basis of the above embodiments, continue to refer to Figure 15 and 17 As shown, two third sub-pixel groups 33 adjacently arranged along the extension direction of the sub-pixel row (the X direction shown in the figure) include a first third sub-pixel group 33-1 and a second third sub-pixel group 33-2; the position of the sixth first sub-pixel 116 in the first third sub-pixel group 33-1 in the third virtual quadrilateral 43 is the same as the position of the sixth first sub-pixel 116 in the second third sub-pixel group 33-2 in the third virtual quadrilateral 43, and the first direction X1 in the first third sub-pixel group 33-1 is opposite to the first direction X1 in the second third sub-pixel group 33-2; the position of the seventh first sub-pixel 117 in the first third sub-pixel group 33-1 in the third virtual quadrilateral 43 is the same as the position of the seventh first sub-pixel 117 in the second third sub-pixel group 33-2 in the third virtual quadrilateral 43, and the first third sub-pixel group 33 -1 is opposite to the second direction X2 in the second-third sub-pixel group 33-2; the position of the eighth first sub-pixel 118 in the first-third sub-pixel group 33-1 in the third virtual quadrilateral 43 is the same as the position of the eighth first sub-pixel 118 in the second-third sub-pixel group 33-2 in the third virtual quadrilateral 43, and the third direction X3 in the first-third sub-pixel group 33-1 is opposite to the third direction X3 in the second-third sub-pixel group 33-2; the position of the ninth first sub-pixel 119 in the first-third sub-pixel group 33-1 in the third virtual quadrilateral 43 is the same as the position of the ninth first sub-pixel 119 in the second-third sub-pixel group 33-2 in the third virtual quadrilateral 43, and the fourth direction X4 in the first-third sub-pixel group 33-1 is opposite to the fourth direction X4 in the second-third sub-pixel group 33-2.

[0205] like Figure 15 and 17As shown, the display panel includes a plurality of third sub-pixel groups 33, and the plurality of third sub-pixel groups 33 include a first third sub-pixel group 33-1 and a second third sub-pixel group 33-2 that are adjacently arranged in the extension direction X of the sub-pixel row. The first third sub-pixel group 33-1 and the second third sub-pixel group 33-2 share a first sub-pixel, that is, there is a first sub-pixel that is located in both the first third sub-pixel group 33-1 and the second third sub-pixel group 33-2. Figure 17 For example, the seventh first sub-pixel 117 in the first third sub-pixel group 33-1 also serves as the ninth first sub-pixel 119 in the second third sub-pixel group 33-2. Furthermore, in the first third sub-pixel group 33-1 and the second third sub-pixel group 33-2, the two first sub-pixels with the same position have their pixel emission areas with centers of gravity pointing to opposite directions of the first shape segment 201, that is, in the first third sub-pixel group 33-1 and the second third sub-pixel group 33-2, the two first directions X1 are opposite, the two second directions X2 are opposite, the two third directions X3 are opposite, and the two fourth directions X4 are opposite. Figure 17 As shown in the figure, for example, in the first-third sub-pixel group 33-1, the first direction X1 points to the right, and in the second-third sub-pixel group 33-2, the first direction X1 points to the left; in the first-third sub-pixel group 33-1, the second direction X2 points to the lower direction, and in the second-third sub-pixel group 33-2, the second direction X2 points to the upper direction; in the first-third sub-pixel group 33-1, the third direction X3 points to the left direction, and in the second-third sub-pixel group 33-2, the third direction X3 points to the right direction; in the first-third sub-pixel group 33-1, the fourth direction X4 points to the upper direction, and in the second-third sub-pixel group 33-2, the fourth direction X4 points to the lower direction. That is, for the first third subpixel group 33-1, the sixth first subpixel 116, the seventh first subpixel 117, the eighth first subpixel 118, and the ninth first subpixel 119, which are arranged in the first clockwise direction, have their first direction X1, second direction X2, third direction X3, and fourth direction X4 also arranged in the first clockwise direction. For the second third subpixel group 33-2, the sixth first subpixel 116, the seventh first subpixel 117, the eighth first subpixel 118, and the ninth first subpixel 119, which are arranged in the first clockwise direction, have their first direction X1, fourth direction X4, third direction X3, and second direction X2 arranged in the second clockwise direction. That is, for two third subpixel groups adjacent to each other in the extension direction X of the subpixel row, the centers of gravity of the multiple first subpixels are evenly distributed, and the centers of gravity of the pixel emissive areas point in different directions toward the first shape segment 201. This prevents four-way color shift and ensures the display quality of the display panel.

[0206] For further reference, Figure 17 As shown, two third sub-pixel groups adjacently arranged along the extension direction of the sub-pixel column (the Y direction shown in the figure) include a third third sub-pixel group 33-3 and a fourth third sub-pixel group 33-4; the extension direction Y of the sub-pixel column intersects the extension direction X of the sub-pixel row; the position of the sixth first sub-pixel 116 in the third third sub-pixel group 33-3 in the third virtual quadrilateral 43 is the same as the position of the sixth first sub-pixel 116 in the fourth third sub-pixel group 33-4 in the third virtual quadrilateral 43, and the first direction X1 in the third third sub-pixel group 33-3 is opposite to the first direction X1 in the fourth third sub-pixel group 33-4; the position of the seventh first sub-pixel 117 in the third third sub-pixel group 33-3 in the third virtual quadrilateral 43 is the same as the position of the seventh first sub-pixel 117 in the fourth third sub-pixel group 33-4 in the third virtual quadrilateral 43, And the second direction X2 in the third third sub-pixel group 33-3 is opposite to the second direction X2 in the fourth third sub-pixel group 33-4; the position of the eighth first sub-pixel 118 in the third third sub-pixel group 33-3 in the third virtual quadrilateral 43 is the same as the position of the eighth first sub-pixel 118 in the fourth third sub-pixel group 33-4 in the third virtual quadrilateral 43, and the third direction X3 in the third third sub-pixel group 33-3 is opposite to the third direction X3 in the fourth third sub-pixel group 33-4; the position of the ninth first sub-pixel 119 in the third third sub-pixel group 33-3 in the third virtual quadrilateral 43 is the same as the position of the ninth first sub-pixel 119 in the fourth third sub-pixel group 33-4 in the third virtual quadrilateral 43, and the fourth direction X4 in the third third sub-pixel group 33-3 is opposite to the fourth direction X4 in the fourth third sub-pixel group 33-4.

[0207] like Figure 15 and 17 As shown, the display panel includes a plurality of third sub-pixel groups 33, and the plurality of third sub-pixel groups 33 include a third third sub-pixel group 33-3 and a fourth third sub-pixel group 33-4 that are adjacently arranged in the extension direction Y of the sub-pixel column. The third third sub-pixel group 33-3 and the fourth third sub-pixel group 33-4 share a first sub-pixel, that is, there is a first sub-pixel that is located in both the third third sub-pixel group 33-3 and the fourth third sub-pixel group 33-4. Figure 17For example, the eighth first sub-pixel 118 in the third third sub-pixel group 33-3 also serves as the sixth first sub-pixel 116 in the fourth third sub-pixel group 33-4. Furthermore, in the third third sub-pixel group 33-3 and the fourth third sub-pixel group 33-4, the two first sub-pixels with the same position have their pixel emission areas with centers of gravity pointing to opposite directions of the first shape segment 201, that is, in the third third sub-pixel group 33-3 and the fourth third sub-pixel group 33-4, the two first directions X1 are opposite, the two second directions X2 are opposite, the two third directions X3 are opposite, and the two fourth directions X4 are opposite. Figure 17 As shown in the example, in the third third sub-pixel group 33-3, the first direction X1 is the direction pointing to the right, and in the fourth third sub-pixel group 33-4, the first direction X1 is the direction pointing to the left; in the third third sub-pixel group 33-3, the second direction X2 is the direction pointing to the lower side, and in the fourth third sub-pixel group 33-4, the second direction X2 is the direction pointing to the upper side; in the third third sub-pixel group 33-3, the third direction X3 is the direction pointing to the left side, and in the fourth third sub-pixel group 33-4, the third direction X3 is the direction pointing to the right side; in the third third sub-pixel group 33-3, the fourth direction X4 is the direction pointing to the upper side, and in the fourth third sub-pixel group 33-4, the fourth direction X4 is the direction pointing to the lower side. That is, for the third sub-pixel group 33-3, the sixth first sub-pixel 116, the seventh first sub-pixel 117, the eighth first sub-pixel 118, and the ninth first sub-pixel 119, which are arranged in the first clockwise direction, have their first direction X1, second direction X2, third direction X3, and fourth direction X4 also arranged in the first clockwise direction. For the fourth sub-pixel group 33-4, the sixth first sub-pixel 116, the seventh first sub-pixel 117, the eighth first sub-pixel 118, and the ninth first sub-pixel 119, which are arranged in the first clockwise direction, have their first direction X1, fourth direction X4, third direction X3, and second direction X2 arranged in the second clockwise direction. That is, for two adjacent third sub-pixel groups arranged in the extension direction Y of the sub-pixel column, the centers of gravity of the multiple first sub-pixels are evenly distributed, and the centers of gravity of the pixel emission areas point in different directions toward the first shape segment 201. This prevents four-way color shift and ensures the display quality of the display panel.

[0208] On the basis of the above embodiments, continue to refer to Figure 20 and Figure 21As shown, the display panel further includes a plurality of fourth sub-pixel groups 34, the fourth sub-pixel group 34 includes a plurality of first sub-pixels having the same luminescent color, the plurality of first sub-pixels include a tenth first sub-pixel 1110, an eleventh first sub-pixel 1111, a twelfth first sub-pixel 1112, and a thirteenth first sub-pixel 1113, and the luminescent colors of the tenth first sub-pixel 1110, the eleventh first sub-pixel 1111, the twelfth first sub-pixel 1112, and the thirteenth first sub-pixel 1113 are the same as those of the sixth first sub-pixel 116, the seventh first sub-pixel 117, and the fourth sub-pixel 118. The luminous colors of the eighth first sub-pixel 118 and the ninth first sub-pixel 119 are different; the tenth first sub-pixel 1110, the eleventh first sub-pixel 1111, the twelfth first sub-pixel 1112 and the thirteenth first sub-pixel 1113 form a fourth virtual quadrilateral 44, and the centers of gravity of the tenth first sub-pixel 1110, the eleventh first sub-pixel 1111, the twelfth first sub-pixel 1112 and the thirteenth first sub-pixel 1113 are respectively located at the four vertices of the fourth virtual quadrilateral 44; the pixel emission area has a first shape 20, and the first shape of the first sub-pixel The shape includes at least one first shape segment 201, and the first shape segment 201 includes a curve; in the tenth first sub-pixel 1110, the direction in which the center of gravity of the pixel emission area points to the first shape segment 201 is the fifth direction X5; in the eleventh first sub-pixel 1111, the direction in which the center of gravity of the pixel emission area points to the first shape segment 201 is the sixth direction X6; in the twelfth first sub-pixel 1112, the direction in which the center of gravity of the pixel emission area points to the first shape segment 201 is the seventh direction X7; in the thirteenth first sub-pixel 113, the direction in which the center of gravity of the pixel emission area points to the first shape segment 201 is the seventh direction X8. The direction of a shape segment 201 is the eighth direction X8; wherein, the tenth first sub-pixel 1110, the eleventh first sub-pixel 1111, the twelfth first sub-pixel 1112 and the thirteenth first sub-pixel 1113 are arranged along the second clockwise direction, and the sixth direction X5 is rotated 90° along the second clockwise direction relative to the fifth direction X5, the seventh direction X7 is rotated 90° along the second clockwise direction relative to the sixth direction X6, and the eighth direction X8 is rotated 90° along the second clockwise direction relative to the seventh direction X7; the second clockwise direction is the same as or opposite to the first clockwise direction.

[0209] like Figure 20 and Figure 21As shown, the display panel includes a plurality of fourth subpixel groups 34, and the fourth subpixel group 34 includes a tenth first subpixel 1110, an eleventh first subpixel 1111, a twelfth first subpixel 1112, and a thirteenth first subpixel 1113, which emit the same luminescent color. Furthermore, the luminescent colors of the tenth first subpixel 1110, the eleventh first subpixel 1111, the twelfth first subpixel 1112, and the thirteenth first subpixel 1113 are different from the luminescent colors of the sixth first subpixel 116, the seventh first subpixel 117, the eighth first subpixel 118, and the ninth first subpixel 119. The tenth first sub-pixel 1110 is located in a sub-pixel row; the eleventh first sub-pixel 1111 and the thirteenth first sub-pixel 1113 are located in the same sub-pixel row and the eleventh first sub-pixel 1111 and the thirteenth first sub-pixel 1113 are the two closest first sub-pixels of the same color in the same sub-pixel row; the twelfth first sub-pixel 1112 is located in a sub-pixel row; and the sub-pixel row where the tenth first sub-pixel 1110 is located, the sub-pixel row where the eleventh first sub-pixel 1111 and the thirteenth first sub-pixel 1113 are located, and the sub-pixel row where the twelfth first sub-pixel 1112 is located are the three sub-pixel rows that contain first sub-pixels and are closest to each other. Furthermore, the tenth first sub-pixel 1110, the eleventh first sub-pixel 1111, the twelfth first sub-pixel 1112, and the thirteenth first sub-pixel 1113 form a fourth virtual quadrilateral 44, and the centers of gravity of the tenth first sub-pixel 1110, the eleventh first sub-pixel 1111, the twelfth first sub-pixel 1112, and the thirteenth first sub-pixel 1113 are respectively located at the four vertices of the fourth virtual quadrilateral 44. Furthermore, for the tenth first sub-pixel 1110, the center of gravity of its pixel emission area O 110 The direction pointing to the first shape segment 201 is the fifth direction X5; for the eleventh first sub-pixel 1111, the center of gravity of its pixel emission area O 111 The direction pointing to the first shape segment 201 is the sixth direction X6; for the twelfth first sub-pixel 1112, the center of gravity of its pixel emission area O 112 The direction pointing to the first shape segment 201 is the seventh direction X7; for the thirteenth first sub-pixel 1113, the center of gravity of its pixel emission area O 113 The direction pointing to the first shape segment 201 is the eighth direction X8; in the embodiment of the present application, the direction in which the center of gravity of the pixel emission area points to the first shape segment can also be understood as the convex direction of the first shape segment relative to the center of gravity of the pixel emission area. In the embodiment of the present application, the fifth direction X5, the sixth direction X6, the seventh direction X7 and the eighth direction X8 are different. Figure 21 For example, the fifth direction X5, the sixth direction X6, the seventh direction X7 and the eighth direction X8 are distributed in the four directions of up, down, left and right, which is beneficial to avoid the four-directional color deviation of the display panel and improve the display effect of the display panel.

[0210] For further reference, Figure 20 and Figure 21 As shown, the tenth first sub-pixel 1110, the eleventh first sub-pixel 1111, the twelfth first sub-pixel 1112 and the thirteenth first sub-pixel 1113 are arranged along the second clockwise direction, where the second clockwise direction can be clockwise or counterclockwise, that is, the second clockwise direction can be the same as or opposite to the first clockwise direction. Figure 20 and Figure 21 Taking the second clockwise direction as the clockwise direction, that is, the second clockwise direction being the same as the first clockwise direction, for example, when the tenth first sub-pixel 1110, the eleventh first sub-pixel 1111, the twelfth first sub-pixel 1112, and the thirteenth first sub-pixel 1113 are arranged along the first clockwise direction, the fifth direction X5, the sixth direction X6, the seventh direction X7, and the eighth direction X8 are also arranged along the first clockwise direction. That is, the sixth direction X6 is rotated 90° along the first clockwise direction relative to the fifth direction X5, the seventh direction X7 is rotated 90° along the first clockwise direction relative to the sixth direction X6, and the eighth direction X8 is rotated 90° along the first clockwise direction relative to the seventh direction X7. While ensuring a uniform distribution of the centers of gravity of the tenth first sub-pixel 1110, the eleventh first sub-pixel 1111, the twelfth first sub-pixel 1112, and the thirteenth first sub-pixel 1113, four-way color shift of the display panel can be avoided, thereby improving the display quality of the display panel.

[0211] Furthermore, the second clockwise direction is the same as the first clockwise direction; the sixth first sub-pixel 116 and the tenth first sub-pixel 1110 are located in the same sub-pixel row and are adjacent to each other along the extension direction of the sub-pixel row, and the first direction X1 and the fifth direction X5 are the same; the seventh first sub-pixel 117 and the eleventh first sub-pixel 1111 are located in the same sub-pixel row and are adjacent to each other along the extension direction of the sub-pixel row, and the second direction X2 and the sixth direction X6 are the same; the eighth first sub-pixel 118 and the twelfth first sub-pixel 1112 are located in the same sub-pixel row and are adjacent to each other along the extension direction of the sub-pixel row, and the third direction X3 and the seventh direction X7 are the same; the ninth first sub-pixel 119 and the thirteenth first sub-pixel 1113 are located in the same sub-pixel row and are adjacent to each other along the extension direction of the sub-pixel row, and the fourth direction X4 and the eighth direction X8 are the same.

[0212] like Figure 20 and Figure 21As shown, the second clockwise direction is the same as the first clockwise direction. The figure takes the second clockwise direction and the first clockwise direction as an example for explanation. Optionally, the second clockwise direction and the first clockwise direction can also be counterclockwise. In this case, the first direction X1 and the fifth direction X5 are the same. The figure takes the first direction X1 and the fifth direction X5 as an example for explanation. The second direction X2 and the sixth direction X6 are the same. The figure takes the second direction X2 and the sixth direction X6 as an example for explanation. The third direction X3 and the seventh direction X7 are the same. The figure takes the third direction X3 and the seventh direction X7 as an example for explanation. The fourth direction X4 and the eighth direction X8 are the same. The figure takes the fourth direction X4 and the seventh direction X7 as an example for explanation. Further, the sixth first sub-pixel 116 and the tenth first sub-pixel 1110 are two first sub-pixels with different luminous colors located in the same sub-pixel row and adjacent to each other along the extension direction of the sub-pixel row; the seventh first sub-pixel 117 and the eleventh first sub-pixel 1111 are two first sub-pixels with different luminous colors located in the same sub-pixel row and adjacent to each other along the extension direction of the sub-pixel row; the eighth first sub-pixel 118 and the twelfth first sub-pixel 1112 are two first sub-pixels with different luminous colors located in the same sub-pixel row and adjacent to each other along the extension direction of the sub-pixel row; the ninth first sub-pixel 119 and the thirteenth first sub-pixel 1113 are two first sub-pixels with different luminous colors located in the same sub-pixel row and adjacent to each other along the extension direction of the sub-pixel row. The four first sub-pixels in the third sub-pixel group 33 and the four first sub-pixels in the fourth sub-pixel group 34 are set to have the same setting method. The same setting method here can be understood as the center of gravity of the pixel emission area in the first sub-pixel at the same position points to the same direction of the first shape segment. On the premise of ensuring that the four first sub-pixels in the third sub-pixel group 33 and the fourth sub-pixel group 34 have a uniform distribution of the center of gravity, it can also be ensured that the first sub-pixels of different colors in the third sub-pixel group 33 and the fourth sub-pixel group 34 have the same or similar color mixing effects, avoiding the problem of uneven color mixing or color deviation, and ensuring the balance of the overall display of the display panel.

[0213] On the basis of the above embodiments, continue to refer to Figure 22As shown, the multiple sub-pixels also include a first color sub-pixel 10R, a second color sub-pixel 10B and a third color sub-pixel 10G; the multiple first color sub-pixels 10R and the multiple second color sub-pixels 10B constitute a fifth virtual quadrilateral 45, the center of gravity of the first color sub-pixel 10R is at the first vertex of the fifth virtual quadrilateral 45, the center of gravity of the second color sub-pixel 10B is at the second vertex of the fifth virtual quadrilateral 45, the first vertex and the second vertex are alternate and spaced apart, and the third color sub-pixel 10G is inside the fifth virtual quadrilateral 45; the multiple third color sub-pixels 10G constitute a sixth virtual quadrilateral 46, the centers of gravity of the multiple third color sub-pixels 10G are respectively at the vertices of the sixth virtual quadrilateral 46, and the first color sub-pixel 10R or the second color sub-pixel 10B is inside the sixth virtual quadrilateral 46; the first sub-pixel 11 includes the first color sub-pixel 10R and / or the second color sub-pixel 10B.

[0214] like Figure 22 As shown, the first color sub-pixel 10R, the second color sub-pixel 10B and the third color sub-pixel 10G can represent sub-pixels of three different colors, wherein the first color sub-pixel 10R and the second color sub-pixel 10B can be one of a red sub-pixel and a blue sub-pixel respectively and are different, and the third color sub-pixel can be a green sub-pixel.

[0215] The display panel has a plurality of first-color sub-pixels 10R and a plurality of second-color sub-pixels 10B arranged in a pixel arrangement. Two first-color sub-pixels 10R and two second-color sub-pixels 10B form a fifth virtual quadrilateral 45. The center of gravity of the first-color sub-pixel 10R is located at the first vertex of the fifth virtual quadrilateral 45, and the center of the second-color sub-pixel 10B is located at the second vertex of the fifth virtual quadrilateral 45. The first and second vertices of the fifth virtual quadrilateral 45 are alternately arranged. In other words, the two first-color sub-pixels 10R and the two second-color sub-pixels 10B are arranged in a 2*2 arrangement. After the arrangement, the lines connecting the centers of gravity of the four sub-pixels form a quadrilateral, which is defined as the fifth virtual quadrilateral 45. Two first-color sub-pixels 10R are arranged opposite each other along one diagonal of the fifth virtual quadrilateral 45 and are located at two opposite vertices of the fifth virtual quadrilateral 45. Two second-color sub-pixels 10B are arranged opposite each other along another diagonal of the fifth virtual quadrilateral 45 and are located at two other opposite vertices of the fifth virtual quadrilateral 45. The two first-color sub-pixels 10R and the two second-color sub-pixels 10B constitute the fifth virtual quadrilateral 45. A third-color sub-pixel 10G is disposed within the fifth virtual quadrilateral 45. The multiple third-color sub-pixels 10G of the display panel are arranged in a 2x2 pattern to form a sixth virtual quadrilateral 46. The centers of gravity of the third-color sub-pixels 10G are located at the vertices of the sixth virtual quadrilateral 46. That is, when the four third-color sub-pixels 10G are arranged in a 2x2 pattern, the lines connecting their centers of gravity form a quadrilateral, which is defined as the second virtual quadrilateral 15. Based on the pixel arrangement of the first color sub-pixel 10R, the second color sub-pixel 10B, and the third color sub-pixel 10G, a first color sub-pixel 10R is disposed within a portion of the sixth virtual quadrilateral 46, and a second color sub-pixel 10B is disposed within the remaining portion of the sixth virtual quadrilateral 46. This pixel arrangement ensures that the display panel has a good display effect.

[0216] Continue to refer Figure 22 As shown, the fifth virtual quadrilateral 45 includes a first virtual edge 451, a second virtual edge 452, a third virtual edge 453 and a fourth virtual edge 454 connected to each other; the maximum length of the first virtual edge 451, the second virtual edge 452, the third virtual edge 453 and the fourth virtual edge 454 is L5, and the minimum length is L6; wherein, (L5-L6) / L5≤10%.

[0217] like Figure 22As shown, the fifth virtual quadrilateral 45 includes a first virtual side 451, a second virtual side 452, a third virtual side 453 and a fourth virtual side 454 connected, wherein the lengths of the first virtual side 451, the second virtual side 452, the third virtual side 453 and the fourth virtual side 454 are approximately the same. That is, for any one of the first virtual side 451, the second virtual side 452, the third virtual side 453 and the fourth virtual side 454, the lengths of the other virtual sides are approximately the same. The "approximately the same" here can be understood as a length ratio between 0.8 and 1.2. Furthermore, the maximum length L5 and the minimum length L6 of the first virtual side 451, the second virtual side 452, the third virtual side 453 and the fourth virtual side 454 can satisfy (L5-L6) / L5≤10%, further ensuring the length consistency of the first virtual side 451, the second virtual side 452, the third virtual side 453 and the fourth virtual side 454. The first virtual side 451, the second virtual side 452, the third virtual side 453, and the fourth virtual side 454 are set to be substantially the same length, so that there are no long or short sides with significantly different lengths. This ensures a balanced distance between the first color sub-pixel 10R and the second color sub-pixel 10B, thereby ensuring uniform leakage current between the first color sub-pixel 10R and the second color sub-pixel 10B and ensuring a good display effect. Furthermore, the first virtual side 451, the second virtual side 452, the third virtual side 453, and the fourth virtual side 454 are set to be substantially the same length. This reduces restrictions on other structures when they are disposed between the first color sub-pixel 10R and the second color sub-pixel 10B, and the presence of long and short sides does not increase the difficulty of disposing other structures between the first color sub-pixel 10R and the second color sub-pixel 10B, thereby reducing the overall manufacturing difficulty of the display panel.

[0218] For further reference, Figure 26 and Figure 27 As shown, among the four internal angles corresponding to the fifth virtual quadrilateral 45 , the opposite angles are complementary.

[0219] Because the center of gravity of the pixel emission region of at least one of the first color sub-pixel 10R and the second color sub-pixel 10B does not coincide with the center of gravity of the electrode main body, the fifth virtual quadrilateral 45 is an irregular virtual quadrilateral, that is, the fifth virtual quadrilateral 45 is a virtual quadrilateral with a non-rectangular structure. Furthermore, the four corresponding internal angles of the fifth virtual quadrilateral 45 are complementary, that is, the two diagonal angles corresponding to the same color sub-pixels are complementary. In other words, the two diagonal angles corresponding to the same color sub-pixels are not both acute angles or not both obtuse angles.

[0220] Further, such as Figure 26As shown, the first sub-pixel 11 includes a first color sub-pixel 10R or a second color sub-pixel 10B. The four internal angles corresponding to the fifth virtual quadrilateral 45 include one acute angle, one obtuse angle, and two right angles. Furthermore, the two internal angles with the centroid of the pixel emissive area of the first sub-pixel 11 as vertices are respectively an acute angle and an obtuse angle, while the two internal angles with the centroid of the pixel emissive area of the non-first sub-pixel as vertices are both right angles. Figure 26 Take the first sub-pixel including the first color sub-pixel 10R as an example for description. Figure 26 As shown, the first subpixel includes a first color subpixel 10R; the four internal angles corresponding to the fifth virtual quadrilateral include a first internal angle, a second internal angle, a third internal angle, and a fourth internal angle. The vertex of the first internal angle is the center of gravity of the pixel emission area in the first color subpixel 10R, the vertex of the second internal angle is the center of gravity of the pixel emission area in the second color subpixel 10B, the vertex of the third internal angle is the center of gravity of the pixel emission area in the first color subpixel 10R, and the vertex of the fourth internal angle is the center of gravity of the pixel emission area in the second color subpixel 10B. The first internal angle is an acute angle, the third internal angle is an obtuse angle, and the second and fourth internal angles are both right angles. For example, the first internal angle can be 89.58° and the third internal angle can be 90.42°.

[0221] like Figure 27 As shown, the first sub-pixel 11 includes a first color sub-pixel 10R and a second color sub-pixel 10B. The four internal angles corresponding to the fifth virtual quadrilateral 45 include two acute angles and two obtuse angles. The two opposite angles corresponding to the first sub-pixels of the same color include one acute angle and one obtuse angle. That is, the two opposite angles corresponding to the first color sub-pixel 10R include one acute angle and one obtuse angle, and the two opposite angles corresponding to the second color sub-pixel 10B include one acute angle and one obtuse angle.

[0222] To sum up, in the same fifth virtual quadrilateral, the first sub-pixel of the same color corresponds to two internal angles, which are acute angles and obtuse angles respectively, rather than both acute angles or both obtuse angles. This ensures that the setting method of the internal angles in the fifth virtual quadrilateral matches the adjustment method of the center of gravity of the pixel emission area in the first sub-pixel, and ensures that the internal angles in the fifth virtual quadrilateral are reasonably distributed. This avoids the situation where the display difference between the non-right-angle concentrated setting area and other areas due to the non-right-angle concentrated setting is large, thereby ensuring that the overall display balance of the display panel is good.

[0223] Continue to refer Figure 28 and Figure 29 As shown, among the four inner angles with the center of gravity of the pixel emission area of the first sub-pixel as the common vertex, the opposite angles are complementary.

[0224] like Figure 28 and Figure 29As shown, the four inner angles with the center of gravity of the pixel emission area of the first sub-pixel as a common vertex can be understood as the four inner angles corresponding to the first sub-pixel in the four fifth virtual quadrilaterals 45 with the center of gravity of the pixel emission area of the first sub-pixel as a common vertex. Figure 28 and Figure 29 As shown, among the four internal angles with the center of gravity of the pixel emission area of the first sub-pixel as the common vertex, the opposite angles are complementary, that is, the sum of the angles between the opposite angles is 180°. Moreover, among the four internal angles with the center of gravity of the pixel emission area of the first sub-pixel as the common vertex, there are two acute angles and two obtuse angles, that is, among the four internal angles with the center of gravity of the pixel emission area of the first sub-pixel as the common vertex, one group of opposite angles includes one acute angle and one obtuse angle, and the other group of opposite angles also includes one acute angle and one obtuse angle that are complementary. Figure 28 As shown, the first sub-pixel, that is, the first color sub-pixel 10R, has four internal angles with the center of gravity as the common vertex. One set of opposite angles includes an acute angle and an obtuse angle, and the two angles are complementary. The other set of opposite angles also includes an acute angle and an obtuse angle, and the two angles are complementary. Figure 29 As shown, of the four interior angles of the first subpixel (i.e., first color subpixel 10R and second color subpixel 10B) with their centers of gravity serving as common vertices, one set of opposite angles includes an acute angle and an obtuse angle, both of which are complementary; the other set of opposite angles also includes an acute angle and an obtuse angle, both of which are complementary. This ensures that the acute and obtuse angles in the fifth virtual quadrilateral 45 are separated diagonally, avoiding the situation where the acute and obtuse angles are concentrated diagonally, resulting in significant display differences between the areas where the acute or obtuse angles are concentrated and other areas, thereby ensuring a well-balanced display across the entire display panel.

[0225] For further reference, Figure 28 and Figure 29 As shown, among the four internal angles with the center of gravity of the emission area of the first sub-pixel 11 as the common vertex, two obtuse angles are located on one side of the virtual line VL, and two acute angles are located on the other side of the virtual line; the pixel emission area has a first shape 20, and the first shape 20 of the first sub-pixel includes at least one first shape segment 201, and the first shape segment 201 includes a curve; the extension direction of the virtual line VL intersects with the direction in which the center of gravity of the emission area of the first sub-pixel 11 points to the first shape segment 201.

[0226] like Figure 28 and Figure 29 As shown, the extension direction of the virtual line VL here intersects with the direction in which the center of gravity of the emission area of the first sub-pixel 11 points to the first shape segment 201. Figure 28 and Figure 29The following example illustrates that the direction in which the center of gravity of the emission area of the first sub-pixel 11 points to the first shape segment 201 is the vertical direction, and the direction in which the virtual line VL extends is the horizontal direction. Of the four internal angles with the center of gravity of the emission area of the first sub-pixel as the common vertex, two obtuse angles are located on one side of the virtual line VL, and two acute angles are located on the other side of the virtual line VL, as shown in FIG. Figure 28 and Figure 29 As shown, the two obtuse angles are located above the virtual line VL, and the two acute angles are located below the virtual line VL. Reasonable setting of the angles of the four internal angles with the center of gravity of the emissive area of the first sub-pixel 11 as a common vertex can ensure that the angle setting matches the offset method of the center of gravity of the pixel emissive area in the first sub-pixel, ensuring that the angle distribution of the four internal angles with the center of gravity of the emissive area of the first sub-pixel 11 as a common vertex is reasonable.

[0227] For further reference, Figure 29 As shown, the first sub-pixel 11 includes a first color sub-pixel 10R and a second color sub-pixel 10B; the area of the pixel emission region in the first color sub-pixel 10R is smaller than the area of the pixel emission region in the second color sub-pixel 10B; the angle of the acute angle with the center of gravity of the pixel emission region in the first color sub-pixel as the vertex is greater than the angle of the acute angle with the center of gravity of the pixel emission region in the second color sub-pixel as the vertex.

[0228] Specifically, when the degree of offset of the center of gravity of the pixel emission area compared to the center of gravity of the electrode body is the same, for example, the offset is 1 / 5 of the radius of the electrode body, the larger the area of the pixel emission area, the greater the absolute offset of the center of gravity of the pixel emission area and the center of gravity of the electrode body. Therefore, when the first color sub-pixel 10R and the second color sub-pixel 10B are both first sub-pixels, when the area of the pixel emission area in the first color sub-pixel 10R is smaller than the area of the pixel emission area in the second color sub-pixel 10B, the offset of the center of gravity of the pixel emission area in the first color sub-pixel 10R compared to the center of gravity of the electrode body is smaller than the offset of the center of gravity of the pixel emission area in the second color sub-pixel 10B compared to the center of gravity of the electrode body. The smaller the offset, the smaller the change in the corresponding internal angle in the fifth virtual quadrilateral 45, that is, when the internal angle is acute or obtuse, the smaller the change from a right angle. Thus, when the area of the pixel emissive area in the first color sub-pixel 10R is smaller than the area of the pixel emissive area in the second color sub-pixel 10B, the acute angle with the center of gravity of the pixel emissive area in the first color sub-pixel as the vertex is greater than the acute angle with the center of gravity of the pixel emissive area in the second color sub-pixel as the vertex, ensuring that the angle setting method matches the center of gravity offset of the first sub-pixels of different colors, that is, matches the area of the pixel emissive area of the first sub-pixel. For example, the acute angle with the center of gravity of the pixel emissive area in the first color sub-pixel 10R as the vertex can be 89.58°, and the acute angle with the center of gravity of the pixel emissive area in the second color sub-pixel 10B as the vertex can be 89.46°.

[0229] It should be noted that Figure 29 The following example illustrates the case where the area of the pixel emissive region in the first color sub-pixel 10R is smaller than the area of the pixel emissive region in the second color sub-pixel 10B, and the acute angle with the center of gravity of the pixel emissive region in the first color sub-pixel as its vertex is greater than the acute angle with the center of gravity of the pixel emissive region in the second color sub-pixel as its vertex. It is understood that when the area of the pixel emissive region in the first color sub-pixel 10R is larger than the area of the pixel emissive region in the second color sub-pixel 10B, the acute angle with the center of gravity of the pixel emissive region in the first color sub-pixel as its vertex is smaller than the acute angle with the center of gravity of the pixel emissive region in the second color sub-pixel as its vertex.

[0230] Further, Figure 30 This is a schematic structural diagram of the first sixth virtual quadrilateral provided in an embodiment of the present application. Figure 30 As shown, the sixth virtual quadrilateral 46 comprises a regular virtual quadrilateral; the four corresponding internal angles of the sixth virtual quadrilateral 46 are all right angles.

[0231] like Figure 30As shown, the line connecting the centers of gravity of the pixel emission areas of the four third-color sub-pixels 10G forms a sixth virtual quadrilateral. The pixel emission areas of the third-color sub-pixels 10G are regularly shaped, such as circular. In this case, the center of gravity of the pixel emission areas of the third-color sub-pixels 10G coincides with the center of gravity of the electrode body. The four interior angles of the sixth virtual quadrilateral 46 are all right angles, ensuring a regular arrangement of the centers of gravity of the pixel emission areas of the four third-color sub-pixels 10G, ensuring a regular display effect of the third-color sub-pixels 10G, and thus ensuring a good display effect of the entire display panel.

[0232] On the basis of the above embodiments, continue to refer to Figure 2 and 31 As shown, the sub-pixel 10 also includes a first electrode 101, the first electrode 101 includes a connected electrode main portion 1011 and an electrode connecting portion 1012, and the pixel emission area 102 overlaps with the electrode main portion 1011; among the multiple first sub-pixels 11 located in the same sub-pixel row, the centers of gravity of the multiple electrode main portions 1011 are located on the same straight line; and / or, among the multiple first sub-pixels 11 located in the same sub-pixel column, the centers of gravity of the multiple electrode main portions 1011 are located on the same straight line.

[0233] like Figure 31 As shown, in the plurality of first sub-pixels 11 located in the same sub-pixel row, the centers of gravity of the plurality of electrode main bodies 1011 are located on the same straight line, and the extension direction of the straight line can be the direction of the sub-pixel row. Since the display panel also includes other signal lines, such as at least one of a scanning signal line, a light-emitting control signal line, an initialization signal line, and a power signal line extending in the direction of the sub-pixel row, setting the centers of gravity of the plurality of electrode main bodies 1011 in the plurality of first sub-pixels 11 located in the same sub-pixel row to be located on the same straight line is beneficial to the symmetrical arrangement of the signal lines extending in the direction of the sub-pixel row, and achieving regularity in the layout of the signal lines extending in the direction of the sub-pixel row.

[0234] Furthermore, the display panel may also include a light-shielding layer located on the light-emitting side of the sub-pixels. The light-shielding layer includes multiple light-shielding sections. Along the thickness of the display panel, the light-shielding sections cover the aforementioned signal lines to prevent the signal lines from reflecting ambient light and thereby interfering with the light emitted by the display panel. Regular arrangement of the signal lines also ensures the regular arrangement of the light-shielding sections. Regular arrangement of the light-shielding sections facilitates adjustment of the viewing angle and direction of light emitted by the display panel, reduces color shift in all directions of the display panel, and improves the display quality.

[0235] Similarly, in the plurality of first sub-pixels 11 located in the same sub-pixel column, the centers of gravity of the plurality of electrode main bodies 1011 are located on the same straight line, and the extension direction of the straight line can be the direction of the sub-pixel column. Since the display panel also includes other signal lines, such as at least one of a data signal line, a touch signal line, and a power signal line extending in the direction of the sub-pixel column, arranging the centers of gravity of the plurality of electrode main bodies 1011 in the plurality of first sub-pixels 11 located in the same sub-pixel column to be located on the same straight line is beneficial to the symmetric arrangement of the signal lines extending in the direction of the sub-pixel column, thereby achieving a regular layout of the signal lines extending in the direction of the sub-pixel column.

[0236] Furthermore, the display panel may also include a light-shielding layer located on the light-emitting side of the sub-pixels. The light-shielding layer includes multiple light-shielding sections. Along the thickness of the display panel, the light-shielding sections cover the aforementioned signal lines to prevent the signal lines from reflecting ambient light and thereby interfering with the light emitted by the display panel. Regular arrangement of the signal lines also ensures the regular arrangement of the light-shielding sections. Regular arrangement of the light-shielding sections facilitates adjustment of the viewing angle and direction of light emitted by the display panel, reduces color shift in all directions of the display panel, and improves the display quality.

[0237] On the basis of the above embodiments, continue to refer to Figure 31 As shown, the sub-pixel 10 also includes a first electrode 101, the first electrode 101 includes a connected electrode main body 1011 and an electrode connecting portion 1012, and the pixel emission area 02 overlaps with the electrode main body 011; the multiple sub-pixels also include multiple third sub-pixels 13, and the center of gravity of the electrode main body 1011 in the third sub-pixel 13 coincides with the center of gravity of the pixel emission area 102; in the multiple third sub-pixels 13 located in the same sub-pixel row, the centers of gravity of the multiple electrode main bodies 1011 are located on the same straight line; and / or, in the multiple third sub-pixels 13 located in the same sub-pixel column, the centers of gravity of the multiple electrode main bodies 1011 are located on the same straight line.

[0238] like Figure 31 As shown, the third sub-pixel 13 is a sub-pixel in which the center of gravity of the electrode main body 1011 coincides with the center of gravity of the pixel emission area 102, or it can be understood that the third sub-pixel is a sub-pixel in which the shape of the pixel emission area does not change. The third sub-pixel 13 may include the second sub-pixel mentioned in the above embodiment.

[0239] Further, such as Figure 31As shown, in the plurality of third sub-pixels 13 located in the same sub-pixel row, the centers of gravity of the plurality of electrode main bodies 1011 are located on the same straight line, and the extension direction of the straight line can be the direction of the sub-pixel row. Since the display panel also includes other signal lines, such as at least one of a scanning signal line, a light-emitting control signal line, an initialization signal line, and a power supply signal line extending in the direction of the sub-pixel row. Setting the centers of gravity of the plurality of electrode main bodies 1011 in the plurality of third sub-pixels 13 located in the same sub-pixel row to be located on the same straight line is beneficial to the symmetrical setting of the signal lines extending in the direction of the sub-pixel row, and realizing the regularity of the layout of the signal lines extending in the direction of the sub-pixel row. Furthermore, the display panel may also include a light-shielding layer located on the light-emitting side of the sub-pixel, the light-shielding layer including a plurality of light-shielding sections, and the light-shielding sections covering the above-mentioned signal lines along the thickness direction of the display panel to prevent the signal lines from reflecting ambient light and thereby interfering with the light output of the display panel. The regular setting of the signal lines can also ensure the regular setting of the shading divisions. The regularly set shading divisions are conducive to adjusting the light output angle and direction of the display panel, which is conducive to reducing the problem of color deviation in all directions of the display panel and improving the display effect.

[0240] Similarly, in the plurality of third sub-pixels 13 located in the same sub-pixel column, the centers of gravity of the plurality of electrode main bodies 1011 are located on the same straight line, and the extension direction of the straight line can be the direction of the sub-pixel column. Since the display panel also includes other signal lines, such as at least one of a data signal line, a touch signal line, and a power signal line extending in the direction of the sub-pixel column. Setting the centers of gravity of the plurality of electrode main bodies 1011 in the plurality of third sub-pixels 13 located in the same sub-pixel column to be located on the same straight line is beneficial to the symmetrical setting of the signal lines extending in the direction of the sub-pixel column, and realizing the regularity of the layout of the signal lines extending in the direction of the sub-pixel column. Furthermore, the display panel may also include a light-shielding layer located on the light-emitting side of the sub-pixel, the light-shielding layer including a plurality of light-shielding sections, and the light-shielding sections covering the above-mentioned signal lines along the thickness direction of the display panel to prevent the signal lines from reflecting ambient light and thereby interfering with the light output of the display panel. The regular setting of the signal lines can also ensure the regular setting of the shading divisions. The regularly set shading divisions are conducive to adjusting the light output angle and direction of the display panel, which is conducive to reducing the problem of color deviation in all directions of the display panel and improving the display effect.

[0241] Continue to refer Figure 31 As shown, the multiple sub-pixels also include multiple third sub-pixels 13, and the center of gravity of the electrode main body in the third sub-pixel 13 coincides with the center of gravity of the pixel emission area; in the multiple first sub-pixels 11 and the multiple third sub-pixels 13 located in the same sub-pixel row, the centers of gravity of the multiple electrode main bodies are located on the same straight line; and / or, in the multiple first sub-pixels 11 and the multiple third sub-pixels 13 located in the same sub-pixel column, the centers of gravity of the multiple electrode main bodies are located on the same straight line.

[0242] like Figure 31 As shown, in the multiple first sub-pixels 11 and the multiple third sub-pixels 13 located in the same sub-pixel row, the centers of gravity of the multiple electrode main bodies are located on the same straight line. This further simplifies the routing of signal lines extending along the extension direction of the sub-pixel row and increases the convenience of setting up the light-shielding section. The same light-shielding section can simultaneously cover multiple signal lines, reducing the difficulty of manufacturing the light-shielding section. Similarly, in the multiple first sub-pixels 11 and the multiple third sub-pixels 13 located in the same sub-pixel column, the centers of gravity of the multiple electrode main bodies are located on the same straight line. This also further simplifies the routing of signal lines extending along the extension direction of the sub-pixel row and increases the convenience of setting up the light-shielding section. The same light-shielding section can simultaneously cover multiple signal lines, reducing the difficulty of manufacturing the light-shielding section.

[0243] In summary, the display panel provided by the embodiment of the present application realizes reasonable adjustment of the degree of center of gravity offset of the pixel emission area in the first sub-pixel by adjusting the first shape of the first sub-pixel. On the one hand, it ensures that the light-emitting area of the first sub-pixel is less affected and the normal light-emitting area and light-emitting brightness of the first sub-pixel are guaranteed. On the other hand, by reasonably setting the degree of center of gravity offset of the pixel emission area in the first sub-pixel, it ensures that the distance between the first sub-pixel and the first sub-pixel and between the first sub-pixel and other sub-pixels is appropriate, and the display effect of the display panel is well balanced. At the same time, it imposes less restrictions on other structural positions and processes, improves the position of other structures and the degree of freedom of process, and further ensures that the entire structure of the display panel is well uniform and the process difficulty is relatively low. In addition, by adjusting the first shape of the first sub-pixel, a scheme is realized in which the center of gravity of the pixel emission area in the first sub-pixel and the center of gravity of the electrode main body are staggered, which reduces the difficulty of aligning the pixel emission area with the electrode main body and reduces the difficulty of the manufacturing process of the display panel.
