[0084] It should be noted that Figure 2The circumscribed virtual parallelogram 30 corresponding to the sub-pixel is a rectangle. Figure 3 The circumscribed virtual parallelogram 30 corresponding to the sub-pixel is non-rectangular. The shape of the first sub-pixel and the shape of the second sub-pixel can be independently selected as Figure 2 Sub-pixel shape or Figure 3 The sub-pixel shape shown; Exemplarily, the first sub-pixel and the second sub-pixel in the display panel can both be selected Figure 2 Alternatively, the first sub-pixel in the display panel may be selected Figure 2 The second sub-pixel can be selected as Figure 3 Sub-pixel shape shown.

[0085] In this embodiment, the display panel includes a plurality of sub-pixels, which can be divided into three categories, namely, a plurality of first sub-pixels 11, a plurality of second sub-pixels 12, and a plurality of third sub-pixels 13. The colors configured for the first sub-pixel 11, the second sub-pixel 12, and the third sub-pixel 13 can be different. For example, the first sub-pixel 11 can be a red sub-pixel, the second sub-pixel 12 can be a blue sub-pixel, and the third sub-pixel 13 can be a green sub-pixel. However, it is not limited thereto. Relevant practitioners can reasonably configure the colors of the first sub-pixel, the second sub-pixel, and the third sub-pixel according to product requirements. The colors of the first sub-pixel, the second sub-pixel, and the third sub-pixel can be the same, not completely the same, completely different, and so on.

[0086] The plurality of first sub-pixels 11 and the plurality of second sub-pixels 12 of the display panel may be arranged in the following manner: two first sub-pixels 11 and two second sub-pixels 12 form a first virtual quadrilateral 14, the center of gravity Pb11 of the first sub-pixel 11 is located at the first vertex of the first virtual quadrilateral 14, the center of gravity Pb12 of the second sub-pixel 12 is located at the second vertex of the first virtual quadrilateral 14, and the first vertex and the second vertex in the first virtual quadrilateral 14 are alternately arranged. That is, the two first sub-pixels 11 and the two second sub-pixels 12 are arranged in a 2*2 manner, and the center of gravity connection line of the four sub-pixels after arrangement can form a quadrilateral, which is defined as the first virtual quadrilateral 14. Among them, the two first sub-pixels 11 are arranged oppositely along a diagonal line of the first virtual quadrilateral 14 and are located at two opposite vertex positions of the first virtual quadrilateral 14, and the two second sub-pixels 12 are arranged oppositely along another diagonal line of the first virtual quadrilateral 14 and are located at the other two opposite vertex positions of the first virtual quadrilateral 14. The two first sub-pixels 11 and the two second sub-pixels 12 form a first virtual quadrilateral 14 , and a third sub-pixel 13 is disposed inside the first virtual quadrilateral 14 .

[0087] The plurality of third sub-pixels 13 of the display panel may be arranged as follows: a third sub-pixel 13 is disposed inside the first virtual quadrilateral 14, and four third sub-pixels 13 arranged in a 2*2 manner constitute a second virtual quadrilateral 15, and the center of gravity Pb13 of the third sub-pixel 13 is located at the vertex of the second virtual quadrilateral 15. That is, after the four third sub-pixels 13 are arranged in a 2*2 manner, the center of gravity connecting the lines may constitute a quadrilateral, and the quadrilateral is defined as the second virtual quadrilateral 15. Based on the pixel arrangement of the first sub-pixel 11, the second sub-pixel 12, and the third sub-pixel 13, a first sub-pixel 11 is disposed inside a portion of the second virtual quadrilateral 15, and a second sub-pixel 12 is disposed inside a portion of the second virtual quadrilateral 15.

[0088] It should be noted that, as described above, the center of the sub-pixel can be defined as the center point of the geometric shape of the sub-pixel, that is, the geometric center, and the center of gravity of the sub-pixel can be defined as the center point of the mass distribution of the geometric shape of the sub-pixel, that is, the center of mass. If the geometric shape of the sub-pixel is a regular geometric shape, the geometric center of the sub-pixel and its center of gravity coincide. For example, if the shape of the sub-pixel is a parallelogram, the intersection of the two diagonals of the parallelogram is both its geometric center and its center of gravity. If the geometric shape of the sub-pixel is an asymmetric irregular geometric shape, its center of gravity can be determined by relevant techniques, but its geometric center is difficult to determine. At this time, the relative positional relationship between the geometric center of the sub-pixel and its center of gravity is difficult to determine.

[0089] It should be noted that the regular figures (regular geometric shapes) in the present invention meet at least one of the following conditions: 1) central symmetric figures; 2) axial symmetric figures with more than two axes of symmetry. For example, ellipses, parallelograms (non-rectangular and non-rhombus), circles, rounded rectangles, regular polygons, rectangles, rhombuses, etc. are all regular figures. For central symmetric figures, the central symmetry point is the center (center of gravity); for axial symmetric figures with more than two axes of symmetry, the intersection of the two axes of symmetry is the center (center of gravity). Figures other than the corresponding regular figures are irregular figures.

[0090] Taking the third sub-pixel 13 as an example, Figure 1A If the shape of the third sub-pixel 13 is a rectangle, then its geometric center coincides with the center of gravity Pb12, which is specifically the intersection of the two diagonals of the rectangle (i.e., the central symmetric point); however, in practice, the shape of the third sub-pixel is not limited to a rectangle, and the shape of the third sub-pixel can also be other regular geometric shapes, such as a circle, a parallelogram, a rhombus, a regular polygon, etc.; the shape of the third sub-pixel can also be an irregular shape.

[0091] like Figure 1AAs shown, the directions in which the first sub-pixels 11 and the second sub-pixels 12 are alternately arranged include the S1 direction and the S2 direction, and the S1 direction and the S2 direction intersect. In the S1 direction, the first sub-pixels 11 and the second sub-pixels 12 are alternately arranged to form a row of sub-pixels; in the S2 direction, the first sub-pixels 11 and the second sub-pixels 12 are alternately arranged to form a column of sub-pixels. Based on this, the plane formed by the S1 direction and the S2 direction is parallel to the display surface of the display panel, and the thickness direction of the display panel is perpendicular to the display surface of the display panel, that is, the thickness direction of the display panel is perpendicular to the S1 direction and the S2 direction.

[0092] The shape of any one of the first sub-pixel 11 and the second sub-pixel 12 can refer to Figure 2 and Figure 3 As shown. Figure 2 and Figure 3 As shown, the shape of the sub-pixel is a geometric shape surrounded by a first side 21, a second side 22, a third side 23 and a fourth side 24. The first side 21 and the second side 22 are arranged in parallel, the third side 23 is located on the same side of the first side 21 and the second side 22, and the third side 23 connects the first side 21 and the second side 22 on the same side. The first side 21 and the second side 22 are both straight line segments. Specifically, the first side 21 is a straight line segment from point P4 to point P2, and the second side 22 is a straight line segment from point P5 to point P3. The third side 23 is a side formed by connecting a plurality of sub-segments, wherein the plurality of sub-segments of the third side 23 include a first sub-segment 23a and a second sub-segment 23b, wherein one end of the first sub-segment 23a is connected to the first side 21, and one end of the second sub-segment 23b is connected to the second side 22, that is, the third side 23 is formed by connecting the first sub-segment 23a, the second sub-segment 23b, and Ka sub-segments located between the first sub-segment 23a and the second sub-segment 23b, wherein Ka is an integer greater than or equal to 0, and a sub-segment is essentially a line segment. The first segment 23a, the second sub-segment 23b, and the Ka sub-segments located between the first sub-segment 23a and the second sub-segment 23b, any of which may be a straight line segment or an arc segment. Figure 2 and Figure 3 In the example, only the first segment 23a and the second sub-segment 23b are arc segments and Ka=0 are used for explanation. The fourth side 24 is arranged opposite to the third side 23. The fourth side 24 can be a straight line segment, an arc segment, or a side formed by connecting multiple sub-segments. Figure 2 and Figure 3 The fourth side 24 can be a straight line segment. The length relationship between the first side 21 and the second side 22 is not specifically limited. Figure 2 and Figure 3 The length of the first side 21 can be selected to be equal to the length of the second side 22.

[0093] Exemplarily, the third side 23 may include only the first sub-segment 23a and the second sub-segment 23b, then one end of the first sub-segment 23a is connected to the first side 21 and the other end of the first sub-segment 23a is connected to the second sub-segment 23b, one end of the second sub-segment 23b is connected to the second side 22 and the other end of the second sub-segment 23b is connected to the first sub-segment 23a, as shown in FIG. Figure 2 and Figure 3 As shown, the first sub-segment 23a is an arc segment from point P2 to point P1, and the second sub-segment 23b is an arc segment from point P3 to point P1. However, it is not limited thereto. In other embodiments, the third side may include three or more sub-segments, which are the first sub-segment, the second sub-segment, and one or more sub-segments located between and connecting the first sub-segment and the second sub-segment, respectively, without specific limitation.

[0094] like Figure 2 and Figure 3 As shown, the sub-pixel includes a corresponding circumscribed virtual parallelogram 30, and the circumscribed virtual parallelogram 30 is the circumscribed parallelogram of the corresponding sub-pixel. The circumscribed virtual parallelogram 30 includes a first virtual side 31, a second virtual side 32, a third virtual side 33, and a fourth virtual side 34. The first virtual side 31, the second virtual side 32, the third virtual side 33, and the fourth virtual side 34 are all straight line segments. The first virtual side 31 and the second virtual side 32 are arranged in parallel and have the same length. The third virtual side 33 and the fourth virtual side 34 are arranged in parallel and have the same length. The third virtual side 33 is located on the same side of the first virtual side 31 and the second virtual side 32, and the third virtual side 33 connects the first virtual side 31 and the second virtual side 32 on the same side. The fourth virtual side 34 is located on the other side opposite to the third virtual side 33, and the fourth virtual side 34 connects the first virtual side 31 and the second virtual side 32 on the same side. Figure 2 and Figure 3 In the circumscribed virtual parallelogram 30 shown, the first virtual side 31 is a straight line segment from point P4 to point P6, the second virtual side 32 is a straight line segment from point P5 to point P7, the third virtual side 33 is a straight line segment from point P6 to point P7, and the fourth virtual side 34 is a straight line segment from point P4 to point P5.

[0095] For the sub-pixel and its corresponding circumscribed virtual parallelogram, the first virtual edge 31 partially overlaps with the corresponding first edge 21, and at least one point of the first edge 21 may be located on the first virtual edge 31; the second virtual edge 32 partially overlaps with the corresponding second edge 22, and at least one point of the second edge 22 may be located on the second virtual edge 32; and at least one point of the third edge 23 may be located on the corresponding third virtual edge 33.

[0096] Specifically, along the thickness direction of the display panel, the first sub-pixel 11 is located in the corresponding circumscribed virtual parallelogram 30, which can be understood as the points on each side of the first sub-pixel 11 are located inside or on the corresponding side of the circumscribed virtual parallelogram 30, and are not located outside the circumscribed virtual parallelogram 30. Along the thickness direction of the display panel, the second sub-pixel 12 is located in the corresponding circumscribed virtual parallelogram 30, which can be understood as the points on each side of the second sub-pixel 12 are located inside or on the corresponding side of the circumscribed virtual parallelogram 30, and are not located outside the circumscribed virtual parallelogram 30. Figure 2 and Figure 3 As shown, all points of the first side 21 may be located on the first virtual side 31, that is, the first virtual side 31 and the first side 21 have overlapping parts, and the overlapping parts are the straight line segments from point P4 to point P2; all points of the second side 22 may be located on the second virtual side 32, that is, the second virtual side 32 and the second side 22 have overlapping parts, and the overlapping parts are the straight line segments from point P5 to point P3; a point (P1) in the third side 23 may be located on the third virtual side 33, that is, the third virtual side 33 is tangent to the third side 23. If the shape of the sub-pixel changes, the shape of the corresponding circumscribed virtual parallelogram may change accordingly.

[0097] The display panel may include pixel openings corresponding to the plurality of sub-pixels. Figure 4 Schematic diagram of a pixel defining layer provided in an embodiment of the present utility model. Figure 4 As shown, the display panel includes a pixel defining layer 110, the pixel defining layer 110 has a pixel opening corresponding to a plurality of sub-pixels, the inner sidewall of the pixel opening has an inclined structure, and the pixel opening can define the light-emitting area of ​​the corresponding sub-pixel. The pixel defining layer 110 includes a first pixel opening 111 corresponding to defining the first sub-pixel 11, a second pixel opening 112 corresponding to defining the second sub-pixel 12, and a third pixel opening 113 corresponding to defining the third sub-pixel 13. The first pixel opening 111 includes an upper opening 111a, a lower opening 111b, and an inner sidewall 111c connecting the upper opening 111a and the lower opening 111b. The second pixel opening 112 includes an upper opening 112a, a lower opening 112b, and an inner sidewall 112c connecting the upper opening 112a and the lower opening 112b. The third pixel opening 113 includes an upper opening 113a, a lower opening 113b, and an inner sidewall 113c connecting the upper opening 113a and the lower opening 113b.

[0098] Understandably, Figure 2 and Figure 3The sub-pixel area surrounded by the solid line shown in the figure is actually the light-emitting area of ​​the sub-pixel. In the display panel, the pixel opening corresponding to the sub-pixel includes an upper opening and a lower opening, the inner side wall of the pixel opening has an inclined structure, and the cross-sectional shape of the sub-pixel opening along the thickness direction of the display panel should be an inverted trapezoid, that is, the upper opening size is larger and the lower opening size is smaller. Figure 5 yes Figure 4 A cross-sectional view along the middle line A1-A2. Figure 5 and Figure 4 As shown, the cross-sectional shape of the pixel opening along the thickness direction S3 of the display panel is an inverted trapezoid. Based on this, the area of ​​the upper opening 111a of the first pixel opening 111 is larger than the area of ​​the lower opening 111b, the area of ​​the upper opening 112a of the second pixel opening 112 is larger than the area of ​​the lower opening 112b, and the area of ​​the upper opening 113a of the third pixel opening 113 is larger than the area of ​​the lower opening 113b.

[0099] The display panel includes an anode 122, a cathode 123 and a light-emitting layer 124 located between the two on a substrate 121. The light-emitting layer 124 contacts the anode 122 through the pixel opening of the pixel defining layer 110, and the area of ​​the light-emitting layer 124 in contact with the anode 122 is the light-emitting area, that is, the sub-pixel. It can be understood that when the light-emitting layer 124 is evaporated, it will not only adhere to the anode 122, but also evaporate on the pixel defining layer 110. Specifically, the light-emitting layer 124 will be evaporated to the inner side wall of the pixel opening, and even evaporated to the upper opening of the pixel opening. In other words, the lower opening area of ​​the pixel opening is the light-emitting area of ​​the sub-pixel. That is, the lower opening 111b of the first pixel opening 111 defines the shape of the first sub-pixel 11, that is, the light-emitting area, then the first side 21, the second side 22, the third side 23 and the fourth side 24 of the first sub-pixel 11 correspond to the sides of the lower opening 111b of the first pixel opening 111. The lower opening 112b of the second pixel opening 112 defines the shape of the second sub-pixel 12, i.e., the light-emitting area, so the first side 21, the second side 22, the third side 23, and the fourth side 24 of the second sub-pixel 12 correspond to the sides of the lower opening 112b of the second pixel opening 112. The lower opening 113b of the third pixel opening 113 defines the shape of the third sub-pixel 13, i.e., the light-emitting area, so the sides of the third sub-pixel 13 correspond to the sides of the lower opening 113b of the third pixel opening 113.

[0100] Obviously, the circumscribed virtual parallelogram 30 corresponding to the first sub-pixel 11 can be defined as the circumscribed quadrilateral of the lower opening 111b of the first pixel opening 111 corresponding to the first sub-pixel 11, and the circumscribed virtual parallelogram 30 corresponding to the second sub-pixel 12 can be defined as the circumscribed quadrilateral of the lower opening 112b of the second pixel opening 112 corresponding to the second sub-pixel 12.

[0101] In the following text, the area represented by the shape of the sub-pixel specifically refers to the area enclosed by the lower opening edge of the pixel opening corresponding to the sub-pixel, that is, the area of ​​the light-emitting layer in contact with the anode, which is also the light-emitting area of ​​the sub-pixel. The circumscribed virtual parallelogram of the corresponding sub-pixel is the circumscribed quadrilateral of the lower opening edge of the pixel opening, which will not be explained one by one.

[0102] refer to Figure 2 and Figure 3 As shown, for a sub-pixel and its corresponding circumscribed virtual parallelogram, the vertical distance from the intersection point P2 of the first side 21 and the first sub-segment 23a to the third virtual side 33 is the first distance Xa, and the length of the first virtual side 31 is La. Figure 2 and Figure 3 Where La is the length of the straight line segment from point P4 to point P6; Xa and La satisfy the following relationship: 0.05*La≤Xa≤0.3*La. The vertical distance from the intersection point P3 of the second side 22 and the second sub-segment 23b to the third virtual side 33 is the second distance Xb, and the length of the second virtual side 32 is Lb; Xb and Lb satisfy the following relationship: 0.05*Lb≤Xb≤0.3*Lb.

[0103] Understandably, Figure 2 and Figure 3 The sub-pixels and their corresponding circumscribed virtual parallelograms are only examples, which characterize the relative relationship between the sub-pixels and their corresponding circumscribed virtual parallelograms. In the display panel, the first sub-pixel 11 and the second sub-pixel 12 may have different parameters such as shape and area. Based on this, the circumscribed virtual parallelogram corresponding to the first sub-pixel 11 and the circumscribed virtual parallelogram corresponding to the second sub-pixel 12 are different. For example Figure 1A As shown, at least one parameter of the circumscribed virtual parallelogram 30a corresponding to the first sub-pixel 11 and the circumscribed virtual parallelogram 30b corresponding to the second sub-pixel 12 is different from each other in area, side length, internal angle, etc.

[0104] like Figure 2 and Figure 3 As shown, the circumscribed virtual parallelogram 30 corresponding to the sub-pixel is a regular geometric shape with centrosymmetry, so the geometric center of the circumscribed virtual parallelogram 30 coincides with the center of gravity, wherein the geometric center of the circumscribed virtual parallelogram 30 is the intersection point Pa of the two diagonals. The center of gravity of the sub-pixel is Pb. Depending on the change of the geometric shape of the sub-pixel, the center Pa of the circumscribed virtual parallelogram 30 may or may not coincide with the center of gravity Pb ​​of the sub-pixel inside it. Figure 2 and Figure 3 3 and 4 show the case where the center Pa of the circumscribed virtual parallelogram 30 does not coincide with the center of gravity Pb ​​of the sub-pixel inside it.

[0105] Combination Figure 1A , Figure 2 and Figure 3 As shown, the center of the circumscribed virtual parallelogram 30a corresponding to the first sub-pixel 11 is Pa11, and the center of the circumscribed virtual parallelogram 30b corresponding to the second sub-pixel 12 is Pa12.

[0106] In the S1 direction, two adjacent first sub-pixels 11 and second sub-pixels 12 meet at least one of the following conditions: 1) the center line Pa11-Pa12 of the circumscribed virtual parallelogram 30a corresponding to the first sub-pixel 11 and the center line Pa11-Pa12 of the circumscribed virtual parallelogram 30b corresponding to the second sub-pixel 12 intersects the third side of the first sub-pixel 11; 2) the center line Pa11-Pa12 of the circumscribed virtual parallelogram 30a corresponding to the first sub-pixel 11 and the center line 30b of the circumscribed virtual parallelogram 30b corresponding to the second sub-pixel 12 intersects the third side of the second sub-pixel 12. The centroid of the first sub-pixel 11 is Pb11, and the centroid of the second sub-pixel 12 is Pb12.

[0107] In the S2 direction, two adjacent first sub-pixels 11 and second sub-pixels 12 satisfy at least one of the following conditions: 1) the center line Pa11-Pa12 of the circumscribed virtual parallelogram 30a corresponding to the first sub-pixel 11 and the center line Pa11-Pa12 of the circumscribed virtual parallelogram 30b corresponding to the second sub-pixel 12 intersects with the third side of the first sub-pixel 11; 2) the center line Pa11-Pa12 of the circumscribed virtual parallelogram 30a corresponding to the first sub-pixel 11 and the circumscribed virtual parallelogram 30b corresponding to the second sub-pixel 12 intersects with the third side of the second sub-pixel 12.

[0108] Figure 6 is a schematic diagram of another display panel provided by an embodiment of the utility model, such as Figure 6 As shown, in the S1 direction, there are two adjacent first sub-pixels 11 and second sub-pixels 12 that satisfy the following conditions: the center line Pa11-Pa12 of the circumscribed virtual parallelogram 30a corresponding to the first sub-pixel 11 and the center line Pa11-Pa12 of the circumscribed virtual parallelogram 30b corresponding to the second sub-pixel 12 intersects the third side of the first sub-pixel 11 and the third side of the second sub-pixel 12. In the S2 direction, there are two adjacent first sub-pixels 11 and second sub-pixels 12 that satisfy the following conditions: the center line Pa11-Pa12 of the circumscribed virtual parallelogram 30a corresponding to the first sub-pixel 11 and the center line Pa11-Pa12 of the circumscribed virtual parallelogram 30b corresponding to the second sub-pixel 12 intersects the third side of the first sub-pixel 11 and the third side of the second sub-pixel 12.

[0109] Figure 7 yes Figure 1A Schematic diagram of AA1 in. Binding Figure 1A and Figure 7As shown, the first sub-pixel 11 and the second sub-pixel 12 are adjacently arranged in the direction S2. It can be seen that the minimum distance between the circumscribed virtual parallelogram 30b of the second sub-pixel 12 and the opening area of ​​the first sub-pixel 11 is B1, and the minimum distance between the third side of the second sub-pixel 12 and the opening area of ​​the first sub-pixel 11 is B2, and B1 is smaller than B2. It can be understood that B2 is actually the minimum distance between the opening area of ​​the second sub-pixel 12 and the opening area of ​​the first sub-pixel 11. It can be seen that the opening area area of ​​the first sub-pixel 11 is area S a and area S b The sum of the area S b One side of the corresponding shape is the third side of the first sub-pixel 11; the opening area of ​​the second sub-pixel 12 is area S c and area S d The sum of the area S c One side of the corresponding shape is the third side of the second sub-pixel 12 .

[0110] If the circumscribed virtual parallelogram is used as the opening area of ​​the sub-pixel, the minimum distance between the opening areas of the second sub-pixel and the first sub-pixel is B1. In this embodiment, the opening area of ​​the first sub-pixel 11 can be regarded as the opening area of ​​the circumscribed virtual parallelogram 30a with some corner areas cut off, and the opening area of ​​the second sub-pixel 12 can be regarded as the opening area of ​​the circumscribed virtual parallelogram 30b with some corner areas cut off, then the minimum distance between the opening area of ​​the second sub-pixel 12 and the opening area of ​​the first sub-pixel 11 is B2, and B2 is greater than B1. It should be noted that the distance between the opening areas of two adjacent sub-pixels is positively correlated with the lateral leakage current of the two sub-pixels. The smaller the lateral distance between the two adjacent sub-pixels, the greater the lateral leakage current between the two adjacent sub-pixels. Conversely, the larger the distance between the opening areas of the two adjacent sub-pixels, the smaller the lateral leakage current. Based on this, compared with the external virtual parallelogram as the opening area of ​​the sub-pixel, the design of the first sub-pixel 11 and the second sub-pixel 12 in this embodiment can increase the distance between the opening area of ​​the second sub-pixel 12 and the opening area of ​​the first sub-pixel 11, thereby reducing the leakage current between the first sub-pixel 11 and the adjacent second sub-pixel 12, thereby improving the pixel stealing problem and improving the display effect.

[0111] In addition, if the opening of the first sub-pixel 11 is only the area S a In the corresponding part, the opening of the second sub-pixel 12 is only an area S dIn other words, the area of ​​the portion of the sub-pixel corresponding to the third side is removed. This design can increase the distance between the opening areas of two adjacent sub-pixels, but reduces the aperture ratio. In this embodiment, compared with the opening of the first sub-pixel 11 being only the portion corresponding to the area Sa and the opening of the second sub-pixel 12 being only the portion corresponding to the area Sd, the third side of the sub-pixel is designed to be composed of multiple sub-segments and overlap with the third virtual side of the circumscribed virtual parallelogram. Then, the opening area of ​​the first sub-pixel 11 is significantly increased and at least the area Sd is increased. b , the opening area of ​​the second sub-pixel 12 is significantly increased and at least increased by an area S c Compared with the case where the opening of the first sub-pixel 11 is only the portion corresponding to the area Sa and the opening of the second sub-pixel 12 is only the portion corresponding to the area Sd, the aperture ratio of the first sub-pixel 11 and the aperture ratio of the second sub-pixel 12 can be increased in this embodiment, thereby improving the display effect.

[0112] refer to Figure 1A and Figure 1B , Figure 1B : is a schematic diagram of a display panel in the prior art, wherein the first sub-pixel 11y and the second sub-pixel 12y are both squares, the first sub-pixels 11y and the second sub-pixels 12y are arranged alternately along the first direction S1 and the second direction S2, the centers (i.e., the centers of gravity) of two adjacent first sub-pixels 11y and second sub-pixels 12y form a virtual square Qs, a third sub-pixel 13y is located in the virtual square Qs, and the center (i.e., the center of gravity) of the third sub-pixel 13y coincides with the center of the virtual square Qs. If the first sub-pixel 11y is a red sub-pixel R, the second sub-pixel 12y is a blue sub-pixel B, the third sub-pixel 13y is a green sub-pixel G, the pixel center spacing (i.e., the pixel pitch) of the first sub-pixel 11y and the second sub-pixel 12y is PL, the opening spacing (i.e., the spacing of the pixel definition layer, see below for details) is d1, and the opening area of ​​the first sub-pixel 11y is S Ry , the opening area of ​​the second sub-pixel 12y is S By , then under the prior art, the opening areas of the first sub-pixel 11y and the second sub-pixel 12y satisfy:

[0113]

[0114] Among them, k is the coefficient, and after further conversion, we get:

[0115]

[0116] Under the condition of meeting the conventional PPI requirement of the display panel, PL=55um, k=3 (conforming to the tristimulus value of the white point coordinate RGB), then in the prior art: the minimum opening spacing between the first sub-pixel 11y and the second sub-pixel 12y is d1=25um, Xr=10.98um, S Ry =241.12um 2 , S By =723.52um 2 , the minimum opening distance d2 between the third sub-pixel 13y and the first sub-pixel 11y is 18um, the minimum opening distance d3 between the third sub-pixel 13y and the second sub-pixel 12y is 18um, the minimum opening distance d4 between two adjacent third sub-pixels 13y is 35um, and the opening area of ​​the third sub-pixel 13y is S Gy =308.15um 2 A pixel unit includes a first sub-pixel 11y, a second sub-pixel 12y, and two third sub-pixels 13y, and the sum of the opening areas of a pixel unit is S RGBy =1580.94um 2 .

[0117] Figure 1C The display panel and Figure 1B A comparison diagram of the display panels in . Also refer to Fig.19 , Fig.19 is a schematic diagram of a sub-pixel provided by an embodiment of the utility model, in which the first sub-pixel 11 and the second sub-pixel 12 are both Fig.19 The sub-pixels in the figure are used as an example to illustrate. Fig.19 The sub-pixel design in is described in detail below. Figure 1A and Fig.19 , Figure 1CIn the description, an example is given in which the third side of the first sub-pixel 11 includes two arc segments and one straight line segment, the third side of the second sub-pixel 12 includes two arc segments and one straight line segment, the third sub-pixel 13 is an octagon, the circumscribed virtual parallelogram 30a of the first sub-pixel 11 is a square, the circumscribed virtual parallelogram 30b of the second sub-pixel 12 is a square, and the centers of two adjacent circumscribed virtual parallelograms 30a and two circumscribed virtual parallelograms 30b still constitute a virtual square Qs. In the embodiment provided by the present utility model, it is assumed that the minimum opening spacing g1 between the first sub-pixel 11 and the second sub-pixel 12 is 25um, the minimum opening spacing g2 between the third sub-pixel 13 and the first sub-pixel 11 is 18um, the minimum opening spacing g3 between the third sub-pixel 13 and the second sub-pixel 12 is 18um, and the minimum opening spacing g4 between two adjacent third sub-pixels 13 is 35um. In other words, the minimum opening spacing between any two of the first sub-pixel 11, the second sub-pixel 12 and the third sub-pixel 13 in the embodiment of the present utility model and the minimum spacing between two adjacent third sub-pixels 13 are set to be equal to the corresponding minimum opening spacing in the prior art. It should be noted that in the prior art, since the first sub-pixel 11y and the second sub-pixel 12y are both in the positive direction, the minimum opening spacing between the two is the distance along the center line of the sub-pixels (the side of the virtual square Qs). In the embodiment of the present utility model, the minimum opening spacing g1 between the first sub-pixel 11 and the second sub-pixel 12 is not equal to the distance between the two on the side of the virtual square Qs. For example, for the first sub-pixel 11s and the second sub-pixel 12s, the minimum opening distance g1 between the two is the point P24 of the first sub-pixel 11s (refer to Fig.19 , the intersection of the second side 22 and the third side 23) to the right-angle vertex of the second sub-pixel 12s; for the first sub-pixel 11s and the second sub-pixel 12t, the minimum opening spacing g1 between the two is the point P24 of the second sub-pixel 12t (reference Fig.19 , the distance between the intersection of the second side 22 and the third side 23) and the right-angle vertex of the first sub-pixel 11s; the minimum opening spacing between any other adjacent first sub-pixels 11 and second sub-pixels 12 is also the same, and will not be repeated in detail.

[0118] Specifically, refer to Figure 1C , the area of ​​the circumscribed virtual parallelogram 30a of the first subpixel 11s (or the first subpixel 11t) is larger than the area of ​​the first subpixel 11y, and the area of ​​the circumscribed virtual parallelogram 30b of the second subpixel 12s is larger than the area of ​​the second subpixel 12y, that is, compared with the first subpixel 11y, it is equivalent to expanding at least part of the outline of the first subpixel 11 outward; compared with the second subpixel 12y, it is equivalent to expanding at least part of the outline of the second subpixel 12 outward. Reference 2 and Fig.19 , assuming Figure 1C The first sub-pixel 11 corresponds to Xa=Xb=2.8um, the length of the straight line segment from P22 to P23 is 5um, the second sub-pixel 12 corresponds to Xa=Xb=2.7um, the length of the straight line segment from P22 to P23 is 6um, and the calculation results are: S R =261.56um 2 , S B =799.45um 2 , S G =279.84um 2 , the sum of the opening areas of a pixel unit is S RGB =1620.69um 2 .

[0119] Through the above calculation, it is found that compared with the prior art, the total aperture ratio of the display panel can be further improved in the embodiment of the utility model. Figure 1C, although the aperture ratio of the third sub-pixel 13 is reduced, the aperture ratios of the first sub-pixel 11 and the second sub-pixel 12 are increased, so that the total aperture ratio of the display panel is improved. Taking the second sub-pixel 12s as an example, the corresponding circumscribed virtual parallelogram 30b is cut with a larger arc edge, which is equivalent to shrinking the corner away from the first sub-pixel 11s along the first direction S1 and the corner away from the first sub-pixel 11t along the second direction S2, thereby leaving space for the adjacent first sub-pixel 11 to expand outward, and maintaining the minimum opening spacing g1≥d1 between the first sub-pixel 11 and the second sub-pixel 12; and the second sub-pixel 12s, except for the two shrinking corners, expands outward, so that the opening area of ​​the second sub-pixel 12s is increased. For the first sub-pixel 11 and the second sub-pixel 12 in a pixel unit (a first sub-pixel 11, a second sub-pixel 12 and two third sub-pixels 13), the opening area can be increased. Due to the expansion of the first sub-pixel 11 and the second sub-pixel 12, in order to ensure that the minimum opening spacing g2 between the third sub-pixel 13 and the first sub-pixel 11, and the minimum opening spacing g3 between the third sub-pixel 13 and the second sub-pixel 12 can still satisfy g2≥d2, g3≥d3, it is necessary to shrink at least part of the sides of the third sub-pixel 13 (13s) located in the virtual square Qs (i.e., shrink the two sides opposite to each other along the third direction S3 and the two sides opposite to each other along the fourth direction S4), which will cause the opening area of ​​the third sub-pixel 13 to be reduced. However, since the design of the third sub-pixel 13 is not limited to the influence of g2 and g3, it is also limited by the rib width of the evaporation mask plate of two adjacent third sub-pixels 13 in the first direction S1 and the second direction S2. In the display panel, the third sub-pixel 13 is a real resolution, and its number is twice that of the first sub-pixel 11 and twice that of the second sub-pixel 12. In order to ensure the strength of the fine metal mask (FMM), that is, to ensure the rib width of the FMM, the adjacent openings need to be separated by a predetermined interval, so the distance between two adjacent third sub-pixels 13 in the first direction S1 and the second direction S2 will also be limited. However, this limitation will not be further retracted due to the expansion of the first sub-pixel 11 and the second sub-pixel 12, that is, compared with the prior art, in the third sub-pixel 13, the two sides opposite along the first direction S1 and the two sides opposite along the second direction S2 are not retracted, which makes it unnecessary to set the opening area of ​​the third sub-pixel smaller. Therefore, compared with the prior art, the pixel design in the embodiment of the present application can improve the total opening rate (opening area) of the display panel. In addition, the relevant process parameters in the present application (such as the minimum opening spacing between adjacent sub-pixels, FMM rib, etc.) are equal to or better than the prior art.That is to say, while ensuring that the minimum aperture spacing and FMM rib width between adjacent sub-pixels are consistent with the prior art or still have design redundancy, the total aperture ratio of the present application is larger, and the display effect and display quality are better.

[0120] Understandably, reference Figure 1C In the embodiment of the utility model, when the circumscribed virtual parallelogram 30a corresponding to the first sub-pixel 11 is a square, its side length is w1; when the circumscribed virtual parallelogram 30b corresponding to the second sub-pixel 12 is a square, its side length is w2; the shortest distance between the two opposite sides of the third sub-pixel 13 along the third direction S3 is w3, and the shortest distance between the two opposite sides along the fourth direction S4 is w4, wherein w1+w2>w3+w4.

[0121] refer to Figure 1D , Figure 1D is a schematic diagram comparing another display panel provided by an embodiment of the utility model with the prior art. Figure 1B and Figure 1C The difference is that, Figure 1D The third sub-pixel 13y is a rectangle, and the third sub-pixel 13 is a rectangle. Since w1+w2>w3+w4, compared with the prior art, this embodiment can still improve the total aperture ratio of the display panel, thereby improving the display effect and display quality, which will not be repeated here. It can be understood that under the conception of the present utility model, the shape of the third sub-pixel 13 can also be a rounded rectangle, a capsule shape (racetrack shape), etc., and no examples are given one by one.

[0122] It should be noted that the virtual shapes in the various diagrams of the present invention are shown by dashed frames. It can be understood that the dashed frames and related structures such as the connecting lines do not actually exist.

[0123] In the present invention, two first sub-pixels and two second sub-pixels constitute a first virtual quadrilateral, the third sub-pixel is located inside the first virtual quadrilateral, four third sub-pixels constitute a second virtual quadrilateral, and the first sub-pixel or the second sub-pixel is located inside the second virtual quadrilateral, so the sub-pixels in the display panel are evenly distributed and the display effect is better; in the direction in which the first sub-pixel and the second sub-pixel are alternately arranged, the center line of the circumscribed virtual parallelogram corresponding to the first sub-pixel and the circumscribed virtual parallelogram corresponding to the second sub-pixel at least intersects with the third side of one of the first sub-pixel and the second sub-pixel, and the aperture ratio of the first sub-pixel and the second sub-pixel can be increased while maintaining consistency with the existing relevant process parameters (such as the minimum opening spacing between adjacent sub-pixels, FMM rib, etc.), thereby improving the overall aperture ratio of the display panel and thus improving the display effect. In addition, compared with the prior art, if the total aperture ratio of the display panel is kept unchanged, the present application can also increase the distance between the opening areas of the adjacent first sub-pixels and the second sub-pixels, so that the lateral distance between the adjacent first sub-pixels and the second sub-pixels is increased, thereby reducing the leakage between the adjacent first sub-pixels and the second sub-pixels, thereby improving the pixel stealing problem and improving the display effect.

[0124] The above is the core idea of ​​the present invention. The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0125] The shape of the optional circumscribed virtual parallelogram is a rectangle, a square or a rhombus.

[0126] The shape of the circumscribed virtual parallelogram corresponding to the first sub-pixel can be a parallelogram, a rectangle, a square or a rhombus. The shape of the circumscribed virtual parallelogram corresponding to the second sub-pixel can be a parallelogram, a rectangle, a square or a rhombus. The shape of the circumscribed virtual parallelogram corresponding to the first sub-pixel can be the same as the shape of the circumscribed virtual parallelogram corresponding to the second sub-pixel, or the shape of the circumscribed virtual parallelogram corresponding to the first sub-pixel can be different from the shape of the circumscribed virtual parallelogram corresponding to the second sub-pixel.

[0127] like Figure 3 As shown, the shape of the circumscribed virtual parallelogram 30 corresponding to the sub-pixel is a parallelogram, and any internal angle of the parallelogram is not equal to 90°.

[0128] like Figure 2 As shown, the shape of the circumscribed virtual parallelogram 30 corresponding to the sub-pixel is a square, wherein the four internal angles of the circumscribed virtual parallelogram 30 are all 90°, and the lengths of the first virtual side 31, the second virtual side 32, the third virtual side 33 and the fourth virtual side 34 are all equal.

[0129] Figure 8 is a schematic diagram of another sub-pixel provided by an embodiment of the utility model. Figure 8 As shown, the shape of the circumscribed virtual parallelogram 30 corresponding to the sub-pixel is a rectangle, wherein the four internal angles of the circumscribed virtual parallelogram 30 are all 90°, and the length of the third virtual side 33 is not equal to the length of the first virtual side 31 .

[0130] Fig. 9 is a schematic diagram of another sub-pixel provided by an embodiment of the utility model. Fig. 9 As shown, the shape of the circumscribed virtual parallelogram 30 corresponding to the sub-pixel is a rhombus, wherein any internal angle of the circumscribed virtual parallelogram 30 is not equal to 90°, and the length of the third virtual side 33 is equal to the length of the first virtual side 31 .

[0131] As described above, the sub-pixel is located inside the corresponding circumscribed virtual parallelogram 30. As shown in FIG1 , the shape of the circumscribed virtual parallelogram 30a corresponding to the first sub-pixel 11 and the shape of the circumscribed virtual parallelogram 30b corresponding to the second sub-pixel 12 can be the same, such as both being squares. Alternatively, the shape of the circumscribed virtual parallelogram corresponding to the first sub-pixel and the shape of the circumscribed virtual parallelogram corresponding to the second sub-pixel can be different, such as the shape of the circumscribed virtual parallelogram corresponding to the first sub-pixel is Figure 2 The shape of the circumscribed virtual parallelogram corresponding to the second sub-pixel is Figure 3 The parallelogram shown.

[0132] The circumscribed virtual parallelogram 30 is a regular shape whose geometric center and gravity center coincide with each other. According to this pixel arrangement mode, the pixel array in the display panel can be divided into repeated units arranged in an array, which can improve the resolution of the display panel.

[0133] In addition, the sub-pixel is located inside the corresponding circumscribed virtual parallelogram 30, and the shape of the sub-pixel can be flexibly adjusted to change the center of gravity of the sub-pixel, so that the shape of the first virtual quadrilateral changes. The shape of the first virtual quadrilateral affects the color mixing between the first sub-pixel, the second sub-pixel and the third sub-pixel. Therefore, by adjusting the shape of the sub-pixel, the brightness distribution of the display panel can be made more uniform in the pixel arrangement, thereby improving the display effect.

[0134] It should be noted that the sub-pixel is located inside the corresponding circumscribed virtual parallelogram 30, and the shape of the sub-pixel is not limited to the above example, and the shape of the sub-pixel may be an irregular shape or a regular shape. When the shape of the sub-pixel is an irregular shape, its center is difficult to determine, but its center of gravity can be clear. When the shape of the sub-pixel is a regular shape, its center, geometric center and center of gravity coincide. Similarly, as a regular shape, the center of the virtual parallelogram is both the geometric center and the center of gravity.

[0135] Optionally, in the direction in which the first sub-pixels and the second sub-pixels are alternately arranged, a line connecting the centers of a circumscribed virtual parallelogram corresponding to the first sub-pixels and a circumscribed virtual parallelogram corresponding to the second sub-pixels does not intersect the second side.

[0136] refer to Figure 1A , Figure 2 and Figure 3 In this embodiment, the first side and the second side of any one of the first sub-pixel 11 and the second sub-pixel 12 are both straight line segments. Whether in the S1 direction or the S2 direction, the center line Pa11-Pa12 of the circumscribed virtual parallelogram 30a corresponding to the first sub-pixel 11 and the circumscribed virtual parallelogram 30b corresponding to the adjacent second sub-pixel 12 does not intersect with the second sides of the two sub-pixels, nor does it intersect with the first sides of the two sub-pixels.

[0137] For the case where the center line Pa11-Pa12 intersects the third side of the first sub-pixel 11, as shown in FIG. Figure 1A As shown, the central line Pa11-Pa12 also passes through a vertex of the adjacent second sub-pixel 12, and the vertex is the intersection of the first side (or the second side) and the fourth side of the second sub-pixel 12, that is, the intersection of the first side (or the second side) and the fourth side of the second sub-pixel 12 is located on the central line Pa11-Pa12; or Figure 6 As shown, the central line Pa11-Pa12 also intersects the third side of the adjacent second sub-pixel 12; or Figure 6 As shown, the central line Pa11 - Pa12 also intersects with the fourth side of the adjacent second sub-pixel 12 .

[0138] Similarly, for the case where the center line Pa11-Pa12 intersects the third side of the second sub-pixel 12, as shown in FIG1 , the center line Pa11-Pa12 also passes through a vertex of the adjacent first sub-pixel 11, and the vertex is the intersection of the first side (or the second side) and the fourth side of the first sub-pixel 11, that is, the intersection of the first side (or the second side) and the fourth side of the first sub-pixel 11 is located on the center line Pa11-Pa12; or Figure 6 As shown in FIG. 1 , the central line Pa11 - Pa12 also intersects the third side of the adjacent first sub-pixel 11; or Figure 6 As shown, the central line Pa11 - Pa12 also intersects with the fourth side of the adjacent first sub-pixel 11 .

[0139] In the present embodiment, the design of the third side of the first sub-pixel 11 and the third side of the second sub-pixel 12, on the one hand, can increase the aperture ratio of the first sub-pixel 11 and the second sub-pixel 12 while maintaining consistency with existing relevant process parameters (such as the minimum aperture spacing between adjacent sub-pixels, FMM rib, etc.), thereby improving the overall aperture ratio of the display panel and improving the display effect; on the other hand, compared with the prior art, if the total aperture ratio of the display panel is kept unchanged, the present application can also increase the distance between the aperture area of ​​the first sub-pixel 11 and the aperture area of ​​the second sub-pixel 12, so that the lateral distance between the first sub-pixel 11 and the second sub-pixel 12 is increased, the leakage current is reduced, the stealing brightness phenomenon is weakened, and the display effect is improved.

[0140] In order to more clearly illustrate the solution of the utility model, the following embodiments are described in detail based on the shape of the circumscribed virtual parallelogram as a square.

[0141] Optionally, the first subsegment is connected to the second subsegment and a connection point between the two is located at a third virtual edge, the third virtual edge is tangent to the third edge at the connection point, and both the first subsegment and the second subsegment are arc segments.

[0142] refer to Figure 2 As shown, the shape of the first sub-pixel can be independently selected as the shape of the sub-pixel, and / or, the shape of the second sub-pixel can be independently selected as the shape of the sub-pixel. The third side 23 of the sub-pixel only includes the first sub-segment 23a and the second sub-segment 23b, and the first sub-segment 23a and the second sub-segment 23b are both arc segments. The first sub-segment 23a and the second sub-segment 23b are connected and the connection point P1 of the two is located on the third virtual side 33. Based on this, the third virtual side 33 is tangent to the third side 23 at the connection point P1 of the first sub-segment 23a and the second sub-segment 23b.

[0143] refer to Figure 7 and Figure 2 As shown, the third side of the first sub-pixel 11 is composed of two arc segments, and the third side of the second sub-pixel 12 is composed of two arc segments, which can increase the aperture ratio of the first sub-pixel 11, and can also increase the aperture ratio of the second sub-pixel 12. It can also ensure that the distance between the opening areas of the adjacent first sub-pixel 11 and second sub-pixel 12 is large, reduce leakage, improve the problem of stealing brightness, and improve the display effect.

[0144] Combined with the shape of the circumscribed virtual parallelogram 30, the first sub-segment 23a of the third side 23 can be regarded as being formed by chopping the corner area between the first virtual side 31 and the third virtual side 33 of the circumscribed virtual parallelogram 30, and the second sub-segment 23b of the third side 23 can be regarded as being formed by chopping the corner area between the second virtual side 32 and the third virtual side 33 of the circumscribed virtual parallelogram 30.

[0145] refer to Figure 7 As shown, compared with the spacing B1 between two adjacent circumscribed virtual parallelograms (30a and 30b), the third side 23 of the designed sub-pixel is composed of an arc segment, and the distance between the opening area of ​​the first sub-pixel 11 and the adjacent second sub-pixel 12 can be increased to B2. If B2 is greater than B1, the leakage current between the first sub-pixel 11 and the adjacent second sub-pixel 12 can be reduced, the brightness can be reduced, and the display effect can be improved.

[0146] Optionally, the first subsegment and the second subsegment are located on the circumference of the same virtual circle.

[0147] Fig.10 is a schematic diagram of another sub-pixel provided by an embodiment of the utility model. Fig.10 As shown, point P2 is selected on the first virtual side 31 of the circumscribed virtual parallelogram 30, point P3 is selected on the second virtual side 32, and point P1 is selected on the third virtual side 33. A unique virtual circle 35 can be determined based on points P2, P3, and P1. The arc segment from P2 to P1 on the circumference of the virtual circle 35 is determined as the first sub-segment 23a, and the arc segment from P3 to P1 is determined as the second sub-segment 23b. Based on this, the third side 23 of the sub-pixel can be determined. The shape of the sub-pixel in the circumscribed virtual parallelogram 30 can be a non-axisymmetric figure, in which P1 does not coincide with the midpoint of the third virtual side 33, and Xa is not equal to Xb.

[0148] Fig.11 is a schematic diagram of another sub-pixel provided by an embodiment of the utility model. Fig.10 The difference is that, Fig.11 As shown, the shape of the sub-pixel within the circumscribed virtual parallelogram 30 can be an axisymmetric figure, wherein the midpoint of the third virtual side 33 can be determined as point P1, and Xa is equal to Xb. The symmetry axis M1-M2 passes through the midpoint (point P1) of the third virtual side 33, and the shape of the sub-pixel can be a symmetrical structure about the symmetry axis M1-M2.

[0149] The shape of the first sub-pixel can be chosen to be Fig.10 or Fig.11 The shape of the sub-pixel and the shape of the second sub-pixel can be selected as Fig.10 or Fig.11 The shape of the sub-pixel: The shape of the first sub-pixel and the shape of the second sub-pixel may be the same; however, in other embodiments, the shape of the first sub-pixel may be different from the shape of the second sub-pixel.

[0150] 0.5*La≤Ra≤1.5*La may be selected, where the radius of the virtual circle is Ra. The length of the first virtual side of the circumscribed virtual parallelogram corresponding to the sub-pixel is La, and the radius Ra of the virtual circle is designed to be greater than or equal to 0.5*La and less than or equal to 1.5*La.

[0151] Fig.12 is a schematic diagram of another sub-pixel provided by an embodiment of the present utility model, such as Fig.12 As shown, by adjusting the positions of points P2, P3 and P1, different virtual circles 35 can be obtained. Among them, the smallest virtual circle 35 corresponding to points P2, P3 and P1 is the inscribed circle of the circumscribed virtual parallelogram 30, and the inscribed circle is tangent to the first virtual edge 31, the second virtual edge 32 and the third virtual edge 33. The center of the virtual circle 35 is OA, the radius is Ra, and the inscribed circle is the smallest virtual circle 35, so the radius Ra of the virtual circle 35 can be greater than or equal to 0.5*La. If the radius Ra of the virtual circle 35 is less than 0.5*La, the first sub-segment 23a and the second sub-segment 23b cannot be obtained simultaneously through the same virtual circle, that is, it is impossible to achieve that the first sub-segment 23a and the second sub-segment 23b are located on the circumference of the same virtual circle.

[0152] By selecting P2, P3 and P1 at different positions, the obtained virtual circle 35 can also partially overlap with the circumscribed virtual parallelogram. Specifically, the radius Ra of the virtual circle 35 satisfies 0.5*La≤Ra≤1.5*La. Fig.13 is a schematic diagram of another sub-pixel provided by an embodiment of the present utility model, such as Fig.13 As shown, the radius Ra of the virtual circle 35 is less than or equal to 1.5*La. If P2 approaches the end point P6 of the third virtual edge 33 and P3 approaches the end point P7 of the third virtual edge 33, Xa and Xb gradually decrease, and the radius Ra of the virtual circle 35 determined by P2, P1 and P3 gradually increases. However, the radius Ra of the virtual circle 35 should be less than or equal to 1.5*La to ensure the spacing between the opening areas of adjacent sub-pixels, thereby effectively reducing leakage and reducing the problem of stealing light.

[0153] By flexibly designing P1, P2, and P3, virtual circles 35 of different sizes can be obtained, and the curvature of the first subsegment and the curvature of the second subsegment can be adjusted accordingly.

[0154] The optional virtual circle is the circumscribed circle of the circumscribed virtual parallelogram of the corresponding sub-pixel. Fig.14 is a schematic diagram of another sub-pixel provided by an embodiment of the utility model. Fig.14 As shown, the optional first sub-segment 23a and the second sub-segment 23b are located on the circumference of the same virtual circle 35, wherein the virtual circle 35 is equal in size to the circumscribed circle 35x of the circumscribed virtual parallelogram 30 of the sub-pixel.

[0155] By adjusting the positions of points P2, P3 and P1, different virtual circles 35 can be obtained. The size of the virtual circle 35 determined by points P2, P3 and P1 can be equal to the size of the circumscribed circle 35x of the circumscribed virtual parallelogram 30. The virtual circle 35 is tangent to the third virtual side 33 at point P1, intersects with the first virtual side 31 at point P2, and intersects with the second virtual side 32 at point P3. P1 can be the midpoint of the third virtual side 33, then the shape of the sub-pixel can be an axisymmetric figure; or, P1 is not the midpoint of the third virtual side 33, then the shape of the sub-pixel is a non-axisymmetric figure.

[0156] Fig.15 Schematic diagram of a first sub-pixel and a second sub-pixel adjacent to each other along the S2 direction provided by an embodiment of the present utility model. Fig.15 As shown, the circumscribed virtual parallelogram 30a corresponding to the first sub-pixel 11 is designed to be a square, and the circumscribed virtual parallelogram 30b corresponding to the second sub-pixel 12 is designed to be a square. The center distance (Pa11-Pa12) between the circumscribed virtual parallelogram 30a corresponding to the first sub-pixel 11 and the circumscribed virtual parallelogram 30b corresponding to the adjacent second sub-pixel 12 along the S2 direction is 55um, the side length La2 of the circumscribed virtual parallelogram 30b of the second sub-pixel 12 is 28.28μm, and the side length La1 of the circumscribed virtual parallelogram 30a of the first sub-pixel 11 is 21.21μm. This example is taken for the subsequent introduction.

[0157] In solution 1, if the virtual parallelogram 30b circumscribed by the second sub-pixel 12 is used as the pixel opening, the corresponding opening area is 28.28 μm*28.28 μm=800 μm 2 , 800=(2*Se+Sg), Se=17.38μm 2 , Sg=765.2345μm 2 The distance B1 between the circumscribed virtual parallelogram 30 b of the second sub-pixel 12 and the circumscribed virtual parallelogram 30 a of the first sub-pixel 11 along the S2 direction is 20 μm.

[0158] In the embodiment of the utility model, the circumscribed circle of the circumscribed virtual parallelogram is chamfered, and Xb2=3μm to form the opening area of ​​the second sub-pixel 12. Then, the spacing B2 between the opening area of ​​the second sub-pixel 12 and the circumscribed virtual parallelogram 30a of the first sub-pixel 11 along the S2 direction is 22.89μm, and the opening area of ​​the second sub-pixel 12 is 765.23μm. 2Obviously, compared with the case where the opening area of ​​the sub-pixel is the circumscribed virtual parallelogram 30b of the second sub-pixel 12, the spacing between the opening areas of the first sub-pixel 11 and the second sub-pixel 12 along the S2 direction increases by 14.45%, where 14.45% = (22.89-20) / 20; the opening rate of the opening area of ​​the second sub-pixel 12 loses 4.35%, where 4.35% = (800-765.23) / 800.

[0159] In scheme 2, if the circumscribed virtual parallelogram 30b of the second sub-pixel 12 is chamfered with an inscribed circle of radius R (R is less than half of the side length La2 of the circumscribed virtual parallelogram 30b), and R=9um to form the opening area of ​​the second sub-pixel 12, then the spacing Ba between the opening area of ​​the second sub-pixel 12 and the circumscribed virtual parallelogram 30a of the first sub-pixel 11 along the S2 direction is 23.73μm, and the opening area of ​​the second sub-pixel 12 is 751.38μm 2 , of which 751.38μm 2 =Sg-2*Sf, Sf=6.7μm 2 Obviously, by chamfering the circumscribed virtual parallelogram 30b with R=9um to form the sub-pixel opening area, the opening rate of the opening area of ​​the first sub-pixel 11 and the second sub-pixel 12 along the S2 direction loses 6.07%, where 6.07%=(800-751.38) / 800.

[0160] It can be seen that the solution is similar to that in Scheme 1 (B1 = 20 μm, opening area 800 μm 2 ), in the embodiment of the utility model, the sub-pixel spacing B2 is 22.89μm, and the aperture ratio is lost by 4.35%. Compared with Scheme 1, in Scheme 2, the sub-pixel spacing Ba is 23.73μm, and the aperture ratio is lost by 6.07%. Compared with Scheme 2, the embodiment of the utility model loses the aperture area spacing between adjacent sub-pixels, but the aperture ratio is not lost much. Specifically, 22.5% of the gain brought by the reduction of the aperture area spacing is lost, where 22.5% = (23.73-22.89) / (23.73-20), but 39.5% of the aperture ratio loss is compensated, where 39.5% = (6.07%-4.35%) / 4.35%. That is to say, compared with Scheme 2, the embodiment of the utility model can obtain a larger aperture ratio compensation with a smaller aperture area spacing loss gain.

[0161] Optionally, a ratio of the first distance in the first sub-pixel to the length of the first virtual side is not equal to a ratio of the first distance in the second sub-pixel to the length of the first virtual side.

[0162] When the first sub-pixel 11 and the second sub-pixel 12 in the display panel are configured as different colors, the areas of the first sub-pixel 11 and the second sub-pixel 12 are usually different due to the different efficiencies and lifespans of the light-emitting materials of different colors. Therefore, the length of the first virtual side in the first sub-pixel 11 is not equal to the length of the first virtual side in the second sub-pixel 12. When designing the first sub-pixel 11 and the second sub-pixel 12, the first distance in the first sub-pixel 11 and the first distance in the second sub-pixel 12 may be equal or different. Based on this, in the sub-pixel design, the ratio of the first distance in the first sub-pixel 11 to the length of the first virtual side is not equal to the ratio of the first distance in the second sub-pixel 12 to the length of the first virtual side, and the size of the first distance and the first virtual side in each sub-pixel can be flexibly designed.

[0163] Fig.16 is a schematic diagram of another first sub-pixel and a second sub-pixel adjacent to each other along the S2 direction provided by an embodiment of the present utility model. Fig.16 As shown, the first distance Xa1 in the first sub-pixel 11 and the first distance Xa2 in the second sub-pixel 12 can be equal. Since the length La1 of the first virtual edge in the first sub-pixel 11 is not equal to the length La2 of the first virtual edge in the second sub-pixel 12, Xa1 / La1 in the first sub-pixel 11 is not equal to Xa2 / La2 in the second sub-pixel 12.

[0164] However, it is understandable that, under product requirements, the ratio of the first distance in the first sub-pixel to the length of the first virtual side may also be equal to the ratio of the first distance in the second sub-pixel to the length of the first virtual side.

[0165] Optionally, the first subpixel 11 is configured as red, the second subpixel 12 is configured as blue, and the ratio of the first distance Xa1 to the length La1 of the first virtual edge in the first subpixel 11 is greater than the ratio of the first distance Xa2 to the length La2 of the first virtual edge in the second subpixel 12.

[0166] In this embodiment, the first sub-pixel 11 is a red sub-pixel, and the second sub-pixel 12 is a blue sub-pixel. In the display panel, the light-emitting materials of sub-pixels of different colors are different, so that the light-emitting lifespan is also different, wherein the lifespan of the blue sub-pixel is shorter than that of the red sub-pixel. In order to increase the lifespan of the blue sub-pixel, the area of ​​the blue sub-pixel is usually designed to be larger than the area of ​​the red sub-pixel. Therefore, the length La1 of the first virtual side in the first sub-pixel 11 is less than the length La2 of the first virtual side in the second sub-pixel 12.

[0167] refer to Fig.16As shown, the first distance Xa1 in the first sub-pixel 11 and the first distance Xa2 in the second sub-pixel 12 can be equal. Since the area of ​​the red sub-pixel is smaller and the area of ​​the blue sub-pixel is larger, the virtual circle 35a of the first sub-pixel 11 is smaller than the virtual circle 35b of the second sub-pixel 12. Accordingly, the opening area of ​​the first sub-pixel 11 is smaller than the opening area of ​​the second sub-pixel 12. Therefore, the ratio of the first distance Xa1 in the first sub-pixel 11 to the length La1 of the first virtual edge is greater than the ratio of the first distance Xa2 in the second sub-pixel 12 to the length La2 of the first virtual edge.

[0168] Exemplarily, the range of Xa1 / La1 of the red sub-pixel may be 5% to 30%, and Xa1 / La1 may be 23%. The range of Xa2 / La2 of the blue sub-pixel may be 5% to 30%, and Xa2 / La2 may be 16%, but is not limited thereto.

[0169] The first distance Xa1 in the first sub-pixel 11 can be equal to the first distance Xa2 in the second sub-pixel 12. Since the area of ​​the red sub-pixel is smaller and the area of ​​the blue sub-pixel is larger, when Xa1 is equal to Xa2, the virtual circle 35a of the first sub-pixel 11 is smaller than the virtual circle 35b of the second sub-pixel 12, and accordingly, the opening area of ​​the first sub-pixel 11 is smaller than the opening area of ​​the second sub-pixel 12.

[0170] Xa=Xb may be selected. For the first subpixel 11, the vertical distance Xa from the intersection of the first side and the first subsegment to the third virtual side may be equal to the vertical distance Xb from the intersection of the second side and the second subsegment to the third virtual side. For the second subpixel 12, the vertical distance Xa from the intersection of the first side and the first subsegment to the third virtual side may be equal to the vertical distance Xb from the intersection of the second side and the second subsegment to the third virtual side.

[0171] It can be understood that for the first sub-pixel 11, Xa and Xb can be designed differently to adjust the curvature, length and other related parameters of the first sub-segment and the second sub-segment, and Xa and Xb can be reasonably designed based on display requirements; Xa can also be designed to be equal to Xb so that the curvature, length and other parameters of the first sub-segment and the second sub-segment are similar, which is convenient for design. Similarly, Xa and Xb of the second sub-pixel 12 can be designed differently, or Xa corresponding to the second sub-pixel 12 can be designed to be equal to Xb.

[0172] For example, in the display panel of electronic devices such as mobile phones, the La of the red sub-pixel can be designed to be 15.2um, on this basis, the Xa and Xb of the red sub-pixel can be designed to be 3.5um, and the radius of the virtual circle of the red sub-pixel can be 10um; the La of the blue sub-pixel can be designed to be 22.4um, on this basis, the Xa and Xb of the blue sub-pixel can be designed to be 3.5um, and the radius of the virtual circle of the blue sub-pixel can be 19.67um.

[0173] Optionally, the first subsegment is connected to the second subsegment and a connection point between the two is located at a third virtual edge, and the first subsegment and the second subsegment are both straight line segments.

[0174] Fig.17 is a schematic diagram of another sub-pixel provided by an embodiment of the utility model. Fig.17 As shown, the third side 23 of the sub-pixel only includes the first sub-segment 23a and the second sub-segment 23b, and the first sub-segment 23a and the second sub-segment 23b are both straight line segments. The first sub-segment 23a and the second sub-segment 23b are connected, and the connection point P1 of the two is located on the third virtual side 33. The third side 23 of the sub-pixel is composed of two straight line segments, so the sub-segments (the first sub-segment 23a and the second sub-segment 23b) of the third side 23 of the sub-pixel are opposite to the vertex of the adjacent sub-pixel. Combined with the shape of the circumscribed virtual parallelogram 30, the sub-segments of the third side 23 can be regarded as being formed by cutting the two adjacent corners of the circumscribed virtual parallelogram 30, thereby forming the third side 23 of the sub-pixel. For the adjacent first sub-pixel and the second sub-pixel, the cutting angle of the third side of the first sub-pixel can be opposite to the vertex of the adjacent second sub-pixel. On the basis of ensuring a large aperture ratio, the distance between the opening area of ​​the first sub-pixel and the adjacent second sub-pixel can be increased, the problem of stealing brightness is improved, and the display effect is improved.

[0175] Fig.18 is a schematic diagram of another sub-pixel provided by an embodiment of the utility model. Fig.17 The difference is that P1 may coincide with the midpoint of the third virtual side 33, the symmetry axis M1-M2 of the circumscribed virtual parallelogram 30 passes through the midpoint of the third virtual side 33, and the opening shape of the sub-pixel may be symmetrical about the symmetry axis M1-M2.

[0176] The optional third side also includes a third subsegment connecting the first subsegment and the second subsegment on the same side, the third subsegment is a straight line segment and partially overlaps with the third virtual side. The optional first subsegment and the second subsegment are both arc segments. The optional length of the first subsegment is equal to the length of the second subsegment.

[0177] Fig.19 is a schematic diagram of another sub-pixel provided by an embodiment of the present utility model, such as Fig.19As shown, the third side 23 of the sub-pixel includes a first sub-segment 23a, a second sub-segment 23b, and a third sub-segment 23c connecting the first sub-segment 23a and the second sub-segment 23b, and the third sub-segment 23c is a straight line segment. The first sub-segment 23a and the second sub-segment 23b can be arc segments. Select point P21 on the first virtual side 31 of the circumscribed virtual parallelogram 30, select point P24 on the second virtual side 32, and select points P22 and P23 on the third virtual side 33. According to points P21, P22, P23 and P24, a unique virtual circle 35 can be determined. The arc segment from P21 to P22 on the circumference of the virtual circle 35 is determined as the first sub-segment 23a, and the arc segment from P23 to P24 is determined as the second sub-segment 23b, and the straight line segment from P22 to P23 is determined as the third sub-segment 23c. Based on this, the third side 23 of the sub-pixel can be determined. The third sub-segment 23 c is located on the third virtual edge 23 .

[0178] The curvature radius of the first sub-segment 23a can be designed to be equal to the curvature radius of the second sub-segment 23b, or the arc segment length of the first sub-segment 23a can be designed to be equal to the arc segment length of the second sub-segment 23b, but it is not limited thereto. According to display requirements, the curvature radius and arc segment length of the first sub-segment 23a and the second sub-segment 23b can be flexibly designed, and the two can be equal or differentially designed. The first sub-segment 23a and the second sub-segment 23b in the third side 23 are designed as arc segments, which is conducive to increasing the aperture ratio.

[0179] Optionally, both the first sub-segment and the second sub-segment are straight line segments. Fig. 20 is a schematic diagram of another sub-pixel provided by an embodiment of the utility model, and Fig.19 The difference is that Fig. 20 , the first subsegment 23a and the second subsegment 23b are both straight line segments. Select point P21 on the first virtual side 31 of the circumscribed virtual parallelogram 30, select point P24 on the second virtual side 32, select points P22 and P23 on the third virtual side 33, the straight line segment from point P21 to P22 is determined as the first subsegment 23a, the straight line segment from P22 to P23 is determined as the third subsegment 23c, and the straight line segment from P23 to P24 is determined as the second subsegment 23b, based on which the third side 23 of the subpixel can be determined. Among them, the third subsegment 23c is located on the third virtual side 23.

[0180] The straight line length of the first sub-segment 23a can be designed to be equal to the straight line length of the second sub-segment 23b, and / or the angle between the first sub-segment 23a and the first side 21 toward the second side 22 can be designed to be equal to the angle between the second sub-segment 23b and the second side 22 toward the first side 21, but the present invention is not limited thereto. According to display requirements, the slopes and straight line lengths of the first sub-segment 23a and the second sub-segment 23b can be flexibly designed, and the two can be equal or designed differently.

[0181] In other embodiments, it is also possible to select one of the first sub-segment and the second sub-segment as an arc segment, while the other one is a straight line segment.

[0182] The third sub-segment 23c partially overlaps with the third virtual edge 33. Specifically, each point of the third sub-segment 23c may be located on the third virtual edge 33, so that the local straight line segment of the third virtual edge 33 completely overlaps with the third sub-segment 23c, but the present invention is not limited thereto. In combination with the shape of the circumscribed virtual parallelogram 30, the first sub-segment 23a and the second sub-segment 23b of the third edge 23 may be regarded as being formed by chamfering or cutting two adjacent corners of the circumscribed virtual parallelogram 30. On the basis of ensuring a large aperture ratio, the distance between the aperture area of ​​the first sub-pixel and the adjacent second sub-pixel can be increased, thereby improving the problem of stealing brightness and enhancing the display effect.

[0183] The optional circumscribed virtual parallelogram includes a first virtual axis, the center of the circumscribed virtual parallelogram is located on the first virtual axis, the first virtual axis intersects with the third subsegment, and the midpoint of the third subsegment is not on the first virtual axis.

[0184] Fig.21 is a schematic diagram of another sub-pixel provided by an embodiment of the present utility model, such as Fig.21 The circumscribed virtual parallelogram 30 of the sub-pixel shown includes a first virtual axis M1-M2, the midpoint Q1 of the third virtual side 23 and the midpoint Q2 of the fourth virtual side 34 are both located on the first virtual axis M1-M2, and the center Pa of the circumscribed virtual parallelogram 30, i.e., the geometric center, is also located on the first virtual axis M1-M2. On this basis, the first virtual axis M1-M2 intersects with the third sub-segment 23c and the midpoint P25 of the third sub-segment 23c is not on the first virtual axis M1-M2, that is, the third sub-segment 23c is asymmetric about the first virtual axis M1-M2, and the first sub-segment 23a and the second sub-segment 23b connected to the third sub-segment 23c are located on both sides of the first virtual axis M1-M2, so that the parameters such as the radius of curvature, slope or length of the first sub-segment 11d and the second sub-segment 11e can be flexibly designed.

[0185] The optional circumscribed virtual parallelogram includes a first virtual axis, the center of the circumscribed virtual parallelogram is located on the first virtual axis, and the midpoint of the third subsegment is located on the first virtual axis.

[0186] refer to Fig.19 As shown, Fig.21 The difference is that Fig.19The first virtual axis M1-M2 intersects the third subsegment 23c and the midpoint P25 of the third subsegment 23c is located on the first virtual axis M1-M2. If the shape of the circumscribed virtual parallelogram 30 is a square, the third subsegment 23c can be symmetrical about the first virtual axis M1-M2. At this time, the first subsegment 23a and the second subsegment 23b can also be symmetrical about the first virtual axis M1-M2, but are not limited thereto.

[0187] The optional circumscribed virtual parallelogram includes a first virtual axis, the center of the circumscribed virtual parallelogram is located on the first virtual axis, the first virtual axis intersects with the third subsegment, and the first subsegment and the second subsegment are symmetrical about the first virtual axis.

[0188] refer to Fig.19 As shown, the first sub-segment 23a and the second sub-segment 23b can form a symmetrical structure about the first virtual axis M1-M2. Exemplarily, the first sub-segment 23a and the second sub-segment 23b can be the same arc segments and symmetrically distributed on both sides of the first virtual axis M1-M2; but not limited to this, the first sub-segment and the second sub-segment can also be the same straight line segments and symmetrically distributed on both sides of the first virtual axis.

[0189] Based on the above sub-pixel structure, Fig. 22 is a schematic diagram of another display panel provided by an embodiment of the present utility model, such as Fig. 22 As shown, the shape of the first sub-pixel 11 is referenced Fig.19 As shown, the shape of the second sub-pixel 12 is referenced Fig.19 The third side 23 of any one of the first sub-pixel 11 and the second sub-pixel 12 is composed of the first sub-segment 23a, the second sub-segment 23b, and the third sub-segment 23c between the first sub-segment 23a and the second sub-segment 23b.

[0190] It can be selected that Xc≤Lc / 2, wherein the length of the third subsegment is Xc, and the length of the third virtual edge is Lc.

[0191] refer to Fig. 20 As shown, the length of the third sub-segment 23c of the sub-pixel is Xc, the length of the third virtual side 33 of the circumscribed virtual parallelogram 30 of the sub-pixel is Lc, and 2*Xc is designed to be less than or equal to Lc. By reasonably selecting points P22 and P23 on the third virtual side 33 of the circumscribed virtual parallelogram 30, the length of the third sub-segment 23c is adjusted, so that the size of the virtual circle determined by the points P21, P22, P23, and P24 changes, thereby adjusting the aperture ratio of the sub-pixel.

[0192] The ratio of the length of the optional third sub-segment to the length of the third virtual side is 0%-50%. The third sub-segment may account for 0% of the length of the corresponding third virtual side, that is, the third side may only include the first sub-segment and the second sub-segment. The third sub-segment may account for more than 0% of the length of the corresponding third virtual side. At this time, the third side also includes a third sub-segment located between the first sub-segment and the second sub-segment. By reasonably designing the length of the third sub-segment and the positions of the design points P21, P22, P23, and P24, the size of the virtual circle determined by the third sub-segment is changed, thereby adjusting the aperture ratio of the sub-pixel. On the basis of ensuring a large aperture ratio, the distance between the opening area of ​​the first sub-pixel and the adjacent second sub-pixel can be increased, thereby improving the display effect.

[0193] The ratio of the length of the optional third sub-segment to the length of the third virtual side is 5%-40%. If the third sub-segment accounts for more than 0% of the length of the corresponding third virtual side, the third side includes the third sub-segment, and the third side is formed by cutting or chamfering the sub-pixel, which can increase the distance between the opening area of ​​the first sub-pixel and the adjacent second sub-pixel while ensuring a large aperture ratio.

[0194] Optionally, a ratio of the length of the third subsegment to the third virtual edge in the first subpixel is not equal to a ratio of the length of the third subsegment to the third virtual edge in the second subpixel.

[0195] Fig.23 is a schematic diagram of another first sub-pixel and a second sub-pixel adjacent to each other along the S2 direction provided by an embodiment of the present utility model, with reference to Fig.23 As shown, it is designed that Xc1 / Lc1≠Xc2 / Lc2, wherein Xc1 is the length of the third sub-segment of the first sub-pixel 11, Lc1 is the length of the third virtual side of the circumscribed virtual parallelogram 30a corresponding to the first sub-pixel 11, Xc2 is the length of the third sub-segment of the second sub-pixel 12, and Lc2 is the length of the third virtual side of the circumscribed virtual parallelogram 30b corresponding to the second sub-pixel 12. The sizes of different sub-pixels in the display panel may be different, and the first sub-pixel 11 and the second sub-pixel 12 may be sub-pixels of different colors, so the length Lc1 of the third virtual side of the circumscribed virtual parallelogram 30a corresponding to the first sub-pixel 11 may be different from the length Lc2 of the third virtual side of the circumscribed virtual parallelogram 30b corresponding to the second sub-pixel 12. The radius of the virtual circle corresponding to the first sub-pixel 11 is different from the radius of the virtual circle corresponding to the second sub-pixel 12, and accordingly, the opening area of ​​the first sub-pixel 11 is different from the opening area of ​​the second sub-pixel 12, so Xc1 / Lc1≠Xc2 / Lc2.

[0196] Optionally, the first subpixel is configured as red, the second subpixel is configured as blue, and the ratio of the length of the third subsegment to the third virtual edge in the first subpixel is smaller than the ratio of the length of the third subsegment to the third virtual edge in the second subpixel.

[0197] Reference Fig.23 As shown, it is designed that Xc1 / Lc1 < Xc2 / Lc2. The display panel usually includes blue sub-pixels and red sub-pixels. The lifespan of the blue sub-pixels is shorter than that of the red sub-pixels. Therefore, the area of the blue sub-pixels is designed to be larger than that of the red sub-pixels to compensate for the lifespan difference. The first sub-pixel 11 is a red sub-pixel, and the second sub-pixel 12 is a blue sub-pixel. The size of the red sub-pixels is usually smaller than that of the blue sub-pixels. Therefore, the length Lc1 of the third virtual side of the first sub-pixel 11 configured as red is less than the length Lc2 of the third virtual side of the second sub-pixel 12 configured as blue. When designing the first sub-pixel 11 and the second sub-pixel 12, the length Xc1 of the third sub-segment in the first sub-pixel 11 is equal to the length Xc2 of the third sub-segment in the second sub-pixel 12. Based on this, the ratio (Xc1 / Lc1) of the length of the third sub-segment to the length of the third virtual side in the first sub-pixel 11 configured as red is less than the ratio (Xc2 / Lc2) of the length of the third sub-segment to the length of the third virtual side in the second sub-pixel 12. Exemplarily, Xc1 / Lc1 of the first sub-pixel 11 configured as red is equal to 26%, and Xc2 / Lc2 of the second sub-pixel 12 configured as blue is equal to 27%.

[0198] Optionally, the first sub-pixel, the second sub-pixel, and the third sub-pixel are respectively one of a red sub-pixel, a blue sub-pixel, and a green sub-pixel and are all different from each other.

[0199] As shown in Figure 1, optionally, the first sub-pixel 11 is a red sub-pixel, the second sub-pixel 12 is a blue sub-pixel, and the third sub-pixel 13 is a green sub-pixel. The center-of-gravity connection line of two red sub-pixels and two blue sub-pixels arranged adjacent to each other in a 2*2 manner forms a first virtual quadrilateral 14, and the center-of-gravity connection line of four green sub-pixels arranged adjacent to each other in a 2*2 manner forms a second virtual quadrilateral 15. For the first virtual quadrilateral 14, the green sub-pixels therein can be mixed with the adjacent red sub-pixels and blue sub-pixels in the first virtual quadrilateral 14 to improve the display effect.

[0200] Optionally, the center of gravity of the first virtual quadrilateral does not coincide with the center of gravity of the third sub-pixel located inside the first virtual quadrilateral.

[0201] As shown in reference figure 1, the center of gravity of the first virtual quadrilateral 14 is Pd, the center of gravity of the third sub-pixel 13 is Pb13, and the center of gravity Pd of the first virtual quadrilateral 14 does not coincide with the center of gravity Pb13 of the third sub-pixel 13 located inside it. The display panel has a color edge effect when displaying an image, that is, the edge of the displayed image is prone to obvious color stripes that deviate from the original image. Specifically, when the edge of the image includes sequentially arranged red sub-pixels and blue sub-pixels, the red sub-pixels and the blue sub-pixels are easily mixed to form a magenta color edge; when the edge of the image includes sequentially arranged green sub-pixels, it is easy to form a green color edge.

[0202] In this embodiment, the center of gravity Pd of the first virtual quadrilateral 14 does not coincide with the center of gravity Pb13 of the third sub-pixel 13 located inside the first virtual quadrilateral 14, so the position of each first sub-pixel 11 and the position of each second sub-pixel 12 at the vertex position of the first virtual quadrilateral 14 can be flexibly adjusted. When the edge of the display area includes the first sub-pixels 11 and the second sub-pixels 12 arranged alternately, the positions of the first sub-pixels 11 and / or the second sub-pixels 12 can be adjusted so that the center of gravity Pb11 of the first sub-pixel 11 and the center of gravity Pb12 of the second sub-pixel 12 at the edge of the display area are not on a straight line, so that the sensitivity of the human eye to the row (or column) formed by the first sub-pixel 11 and the second sub-pixel 12 at the edge of the display area is reduced, so that the magenta color edge effect can be weakened.

[0203] Optionally, the center of gravity of the second virtual quadrilateral does not coincide with the center of gravity of the first sub-pixel located inside the second virtual quadrilateral; or, the center of gravity of the second virtual quadrilateral does not coincide with the center of gravity of the second sub-pixel located inside the second virtual quadrilateral.

[0204] As shown in reference figure 1, the center of gravity of the second virtual quadrilateral 15 is Pe, the center of gravity of the first sub-pixel 11 is Pb11, and the center of gravity of the second sub-pixel 12 is Pb12. When the sub-pixel located inside the second virtual quadrilateral 15 is the first sub-pixel 11, the center of gravity Pe of the second virtual quadrilateral 15 does not coincide with the center of gravity Pb11 of the first sub-pixel 11 located inside the second virtual quadrilateral 15. When the sub-pixel located inside the second virtual quadrilateral 15 is the second sub-pixel 12, the center of gravity Pe of the second virtual quadrilateral 15 does not coincide with the center of gravity Pb12 of the second sub-pixel 12 located inside the second virtual quadrilateral 15.

[0205] In this embodiment, the center of gravity Pe of the second virtual quadrilateral 15 does not coincide with the center of gravity of the sub-pixel located inside the second virtual quadrilateral 15, so the position of each third sub-pixel 13 at the vertex position of the second virtual quadrilateral 15 can be flexibly adjusted. When the edge of the display area includes the third sub-pixel 13, the position of the third sub-pixel 13 can be adjusted so that the third sub-pixel 13 at the edge of the display area is close to the adjacent first sub-pixel 11 and second sub-pixel 12, which is conducive to the mixed display of the third sub-pixel 13 at the edge of the display area and the adjacent first sub-pixel 11 and second sub-pixel 12, thereby weakening the green color edge effect of the third sub-pixel 13 at the edge of the display area. In addition, adjusting the position of the third sub-pixel 13 at the edge of the display area can also reduce the sensitivity of the human eye to the row (or column) formed by the third sub-pixel 13 at the edge of the display area, so that the green color edge effect can be weakened.

[0206] Fig.24 is a schematic diagram of another display panel provided by an embodiment of the present utility model, such as Fig.24 The optional first sub-pixels 11 and the second sub-pixels 12 are arranged alternately along the first direction S1 and the second direction S2, and the first direction S1 and the second direction S2 intersect; the display panel also includes a plurality of first groups 10, the first group 10 includes four first virtual quadrilaterals 14 arranged along the first direction S1 and adjacent first virtual quadrilaterals 14 have common sides; the four first virtual quadrilaterals 14 in the first group 10 include at least one of a first type virtual quadrilateral 14a, a second type virtual quadrilateral 14b and a third type virtual quadrilateral 14c; at least one internal angle of the first type virtual quadrilateral 14a is not equal to 90° and the angles of the two opposite internal angles are not equal; at least one internal angle of the second type virtual quadrilateral 14b is equal to 90°; at least one internal angle of the third type virtual quadrilateral 14c is not equal to 90° and the angles of any two opposite internal angles are equal. The four first virtual quadrilaterals 14 in the optional first group 10 include two first-type virtual quadrilaterals 14a, one second-type virtual quadrilateral 14b and one third-type virtual quadrilateral 14c, and the arrangement order along the first direction S1 is the first-type virtual quadrilateral 14a, the second-type virtual quadrilateral 14b, the first-type virtual quadrilateral 14a and the third-type virtual quadrilateral 14c.

[0207] It should be noted that the reference Figure 5 ,exist Fig.24 In the figure, the black solid line frame FM1 represents the setting range of the light emitting layer of the first sub-pixel 11, the black solid line frame FM2 represents the setting range of the light emitting layer of the second sub-pixel 12, and the black solid line frame FM3 represents the setting range of the light emitting layer of the first sub-pixel 13. In order to more prominently illustrate the opening conditions of different sub-pixels, the setting range of the light emitting layer of the sub-pixels is indicated by a black solid line frame. It can be understood that the light emitting layers of different colors of adjacent sub-pixels may partially overlap or may not overlap. Fig.24 This is just an example. The same reference numerals represent the same structures, and similar parts will not be repeated below.

[0208] In this embodiment, the direction in which the first sub-pixels 11 and the second sub-pixels 12 are alternately arranged includes a first direction S1 and a second direction S2, the first direction S1 and the second direction S2 intersect, and the angle between the first direction S1 and the second direction S2 may be equal to 90° or may not be equal to 90°. Along the S1 direction, the first sub-pixels 11 and the second sub-pixels 12 are alternately arranged; along the S2 direction, the first sub-pixels 11 and the second sub-pixels 12 are alternately arranged.

[0209] The sub-pixels of the display panel are divided into a plurality of first groups 10. The first group 10 specifically includes 5 first sub-pixels 11 and 5 second sub-pixels 12, and the 10 sub-pixels are arranged in a 2*5 manner. Specifically, the 10 sub-pixels of the first group 10 constitute 4 first virtual quadrilaterals 14 sequentially arranged along the S1 direction, and two adjacent first virtual quadrilaterals 14 share one first sub-pixel 11 and one second sub-pixel 12, so the two adjacent first virtual quadrilaterals 14 have a common edge.

[0210] The four first virtual quadrilaterals 14 in the first group 10 may be at least one of the first type virtual quadrilateral 14a, the second type virtual quadrilateral 14b and the third type virtual quadrilateral 14c in terms of shape. Exemplarily, the four first virtual quadrilaterals 14 in the first group 10 may be the same, or may be the first type virtual quadrilateral 14a, or may be the second type virtual quadrilateral 14b, or may be the third type virtual quadrilateral 14c; the four first virtual quadrilaterals 14 in the first group 10 may also be different, and may be at least two of the first type virtual quadrilateral 14a, the second type virtual quadrilateral 14b and the third type virtual quadrilateral 14c. It should be noted that due to changes in sub-pixel shape, offset, etc., the types of the first virtual quadrilaterals 14 in two different first groups 10 may be different or the same.

[0211] The first type virtual quadrilateral 14a formed by the arrangement of two first sub-pixels 11 and two second sub-pixels 12 has at least one internal angle that is not equal to 90°, and two opposite internal angles are not equal in angle.

[0212] The second type virtual quadrilateral 14b formed by the arrangement of two first sub-pixels 11 and two second sub-pixels 12 has at least one internal angle equal to 90°, wherein the angles of two opposite internal angles may be equal or unequal.

[0213] The third type virtual quadrilateral 14c formed by the arrangement of two first sub-pixels 11 and two second sub-pixels 12 has at least one internal angle that is not equal to 90°, and any two opposite internal angles are equal.

[0214] The four first virtual quadrilaterals 14 in the first group 10 include two first-type virtual quadrilaterals 14a, one second-type virtual quadrilateral 14b, and one third-type virtual quadrilateral 14c, and the arrangement order along the first direction S1 is the first-type virtual quadrilateral 14a, the second-type virtual quadrilateral 14b, the first-type virtual quadrilateral 14a, and the third-type virtual quadrilateral 14c. However, it can be understood that after the positions of the first sub-pixel 11, the second sub-pixel 12, and the third sub-pixel 13 are offset and adjusted, the type and / or order of the first virtual quadrilaterals 14 in the first group 10 may also change accordingly, and no specific examples are given.

[0215] As described above, two first sub-pixels 11 and two second sub-pixels 12 constitute a first virtual quadrilateral 14. If the position of at least one first sub-pixel 11 and / or at least one second sub-pixel 12 is offset, the type of the first virtual quadrilateral 14 is different. By adjusting the position of the first sub-pixel 11 and / or the second sub-pixel 12, different types of first virtual quadrilaterals 14 are formed. In different types of first virtual quadrilaterals 14, the third sub-pixel 13 and the adjacent first sub-pixel 11 and second sub-pixel 12 have different color mixing effects. Therefore, adjusting the position of the first sub-pixel 11 and / or the second sub-pixel 12 is conducive to adjusting the color mixing effect, improving color deviation, and improving the display effect. In particular, for the case where the first sub-pixel 11 and the second sub-pixel 12 are located at the edge of the display area, adjusting the position of the first sub-pixel 11 and / or the second sub-pixel 12 can weaken the color edge phenomenon at the edge of the display area.

[0216] It should be noted that the two first-type virtual quadrilaterals 14a in the first group 10 can be overlapped in the plane by at least one of rotation, translation, mirroring, etc. Exemplarily, the two first-type virtual quadrilaterals 14a in the first group 10 can be overlapped in the plane by rotation and translation. For example, after the first first-type virtual quadrilateral 14a is rotated 180° clockwise, it can be translated along the S1 direction to overlap with the second first-type virtual quadrilateral 14a.

[0217] In other embodiments, two first-type virtual quadrilaterals 14a in the first group 10 can be overlapped in a plane by mirroring and translating. For example, after the first first-type virtual quadrilateral 14a is mirrored and flipped with the S2 direction as the axis, it can be translated along the S1 direction to overlap with the second first-type virtual quadrilateral 14a.

[0218] like Fig.24 As shown, in the optional first type virtual quadrilateral 14a, |α 11 -90°|≤5°,|α 12 -90°|≤5°,|α 13 -90°|≤5°,|α14 -90°|≤5°, where α 11 is the interior angle of the first vertex, α 12 is the interior angle of the second first vertex, α 13 is the interior angle of the first and second vertices, α 14 is the internal angle of the second second vertex; in the third type virtual quadrilateral 14c, |α 31 -90°|≤6°,|α 32 -90°|≤6°,|α 33 -90°|≤6°,|α 34 -90°|≤6°, where α 31 is the interior angle of the first vertex, α 32 is the interior angle of the second first vertex, α 33 is the interior angle of the first and second vertices, α 34 is the internal angle of the second second vertex. In the optional first type virtual quadrilateral 14a, |α 11 -90°|≤2°,|α 12 -90°|≤2°,|α 13 -90°|≤2°,

[0219] |α 14 -90°|≤2°; in the third type virtual quadrilateral 14c, |α 31 -90°|≤3°,

[0220] |α 32 -90°|≤3°,|α 33 -90°|≤3°,|α 34 -90°|≤3°. In the optional first type virtual quadrilateral 14a, 89°<α 11 <90°, 89°<α 12 <90°, 90°<α 13 <91°, 90°<α 14 <91°; in the third type virtual quadrilateral 14c, 88°<α 31 <90°, 88°<α 32 <90°, 90°<α 33 <92°, 90°<α 34 <92°.

[0221] In this embodiment, at least one interior angle of the first type virtual quadrilateral 14a is not equal to 90°, and the angles of the two opposite interior angles are not equal. The shape of the first type virtual quadrilateral 14a can be close to a parallelogram but is not a parallelogram. 11 and α12 The angles are not equal, the two opposite internal angles α 13 and α 14 The angles of α are not equal. 11 , α 12 , α 13 and α 14 At least one of them is not equal to 90°, optional α 11 , α 12 , α 13 and α 14 Are not equal to 90°.

[0226] At least one interior angle of the third type virtual quadrilateral 14c is not equal to 90°, and any two opposite interior angles are equal. The shape of the third type virtual quadrilateral 14c can be a rhombus.

[0265] Based on the above structures of the first sub-pixel and the second sub-pixel, the pixel arrangement of the display panel is not limited to Figure 35-Figure 39 shown.

[0266] for Figure 35-Figure 39 In any one of the pixel arrangements, the connecting line of the centroids of two adjacent first sub-pixels 11 and second sub-pixels 12 satisfies any one of the following conditions: 1) the connecting line intersects with the third side 23x of the first sub-pixel 11 and with the third side 23y of the second sub-pixel 12; 2) the connecting line intersects with the third side 23x of the first sub-pixel 11 and with the fourth side 24y of the second sub-pixel 12; 3) the connecting line intersects with the fourth side 24x of the first sub-pixel 11 and with the third side 23y of the second sub-pixel 12; 4) the connecting line intersects with the fourth side 24x of the first sub-pixel 11 and with the fourth side 24y of the second sub-pixel 12.

[0267] The optional display panel also includes: a plurality of support columns; along the thickness direction of the display panel, the support columns overlap with at least one virtual edge of the first virtual quadrilateral, and the virtual edge intersects with the third edge of at least one of the first sub-pixel and the second sub-pixel.

[0268] Fig.40 is a schematic diagram of another display panel provided by an embodiment of the present utility model, such as Fig.40 As shown, the display panel further includes a plurality of support columns 40, and the support columns 40 are located in the non-opening area 41. Specifically, in combination Figure 4 and Fig.40 As shown, the pixel opening corresponding to the sub-pixel includes a lower opening and an upper opening. Here, the non-opening area 41 can be understood as the pixel defining layer area outside the upper opening area of ​​the pixel defining layer 110, wherein the area defined by 111a represents the upper opening area of ​​the first sub-pixel 11, the area defined by 112a represents the upper opening area of ​​the second sub-pixel 12, and the area defined by 113a represents the upper opening area of ​​the third sub-pixel 13. A plurality of support columns 40 are provided in the non-opening area 41. The support column 40 is used to support the display panel in the thickness direction, and when the display panel is an organic light-emitting display panel, its support column 40 can also support the mask during the evaporation process. The projection of the structure of the support column 40 in the thickness direction of the display panel is a rounded rectangle, but is not limited thereto.

[0269] The center of gravity of the first sub-pixel 11 is Pb11, the center of gravity of the second sub-pixel 12 is Pb12, and the center of gravity of the third sub-pixel 13 is Pb13. Fig.40 Only the centroids of some sub-pixels are shown. The connecting line of the centroids of the two first sub-pixels 11 and the two second sub-pixels 12 forms a first virtual quadrilateral 14. A plurality of support columns 40 are arranged in the non-opening area 41, and at least one support column 40 overlaps with at least one virtual side of the first virtual quadrilateral 14 in the thickness direction of the display panel. The virtual side of the first virtual quadrilateral 14 intersects with the third side of one of the first sub-pixel 11 and the second sub-pixel 12. Compared with the circumscribed virtual parallelogram of the sub-pixel as the opening area, in the embodiment of the utility model, the distance between the opening areas of the first sub-pixel 11 and the second sub-pixel 12 is relatively large, so there is enough space to arrange the support column 40 here, and the support column 40 can maintain a sufficient distance from the opening area of ​​the sub-pixel.

[0270] If the support pillars are too close to the opening of the sub-pixel, they may be squeezed by the mask and other tools during the manufacturing process and fall into the sub-pixel opening area, forming dark spots on the display and affecting the yield. In particular, the current display panels pursue high PPI, and in order to ensure the density of the support pillars, the size of the support pillars cannot be compressed to the limit, resulting in low panel yield.

[0271] In this embodiment, the distance between the opening area of ​​the first sub-pixel 11 and the second sub-pixel 12 at the position of the virtual edge is relatively large, and the position space of the support column 40 is increased, and the position of the support column 40 can be controlled to be far away from the sub-pixel opening area, so that while ensuring the density of the support column, the risk of the support column 40 falling into the sub-pixel opening area can be reduced, thereby improving the manufacturing yield and display effect. Moreover, to a certain extent, the size of the support column 40 can also be increased to ensure the support effect.

[0272] refer to Fig.40 As shown, a first sub-pixel 11, a second sub-pixel 12 and two third sub-pixels 13 can be selected to form a third virtual quadrilateral 42, the center of gravity Pb13 of the two third sub-pixels 13 are located at two opposite vertices of the third virtual quadrilateral 42, and the center of gravity Pb11 of the first sub-pixel 11 and the center of gravity Pb12 of the second sub-pixel 12 are respectively located at the other two opposite vertices of the third virtual quadrilateral 42; the angle range between the extension direction of the third sub-pixel 13 and the extension direction of the support column 40 toward the second sub-pixel 12 is α a , 130°≤α a ≤140°.

[0273] In this embodiment, the projection of the structure of the support column 40 in the thickness direction of the display panel is a rounded rectangle, the rounded rectangle includes a long side and a short side, wherein the length of the long side is greater than the length of the short side, the extension direction of the support column 40 is parallel to the long side of the rounded rectangle, and the size of the support column 40 along the long side of the rounded rectangle is greater than the size of the support column 40 along the short side of the rounded rectangle. The projection of the structure of the third sub-pixel 13 in the thickness direction of the display panel is usually approximately a rectangle, the length of the long side of the rectangle is greater than the length of the short side, the extension direction of the third sub-pixel 13 is parallel to the long side of the rectangle, and the size of the third sub-pixel 13 along the long side of the rectangle is greater than the size of the third sub-pixel 13 along the short side of the rectangle. The angle between the extension direction of the third sub-pixel 13 and the extension direction of the adjacent support column 40 is α a , α a Satisfy 130°≤α a ≤140°. For example, α a Can be 130°, 135°, 139°, etc. Optional α a =135°.

[0274] Based on this, the extension direction of the long axis of the support column 40 points to the third sub-pixel 13, and the short side direction of the support column 40 (perpendicular to its extension direction) points to the first sub-pixel 11 and the second sub-pixel 12. After the support column 40 is arranged in the non-opening area between the first sub-pixel 11 and the second sub-pixel 12, the support column 40 can be spaced relatively large from the opening area of ​​the first sub-pixel 11, thereby reducing the risk of the support column approaching the first sub-pixel and falling into the opening area of ​​the first sub-pixel; the support column 40 can also be spaced relatively large from the opening area of ​​the second sub-pixel 12, thereby reducing the risk of the support column approaching the second sub-pixel and falling into the opening area of ​​the second sub-pixel. Improve production yield and display effect.

[0275] In addition, under high PPI, the spacing between the opening areas of adjacent sub-pixels is small, and in order to ensure the supporting effect of the support column, the size of the support column cannot be compressed to the limit. The spacing between the opening areas of the adjacent first sub-pixels 11 and the second sub-pixels 12 is small under high PPI. If the extension direction of the long axis of the support column 40 points to the first sub-pixel 11 and the second sub-pixel 12, then the risk of the support column 40 falling into the opening area is relatively large. If the spacing between the opening areas of the first sub-pixel 11 and the second sub-pixel 12 is increased in order to reduce the risk of the support column 40 falling into the opening area, the aperture ratio of the first sub-pixel 11 and the second sub-pixel 12 will decrease, thereby reducing the PPI. Therefore, the extension direction of the short axis of the support column 40 points to the first sub-pixel 11 and the second sub-pixel 12, without sacrificing the aperture ratio of the first sub-pixel 11 and the second sub-pixel 12, which is conducive to the display panel to achieve high PPI.

[0276] It should be noted that if the projection of the support column structure in the thickness direction of the display panel is a regular shape, then the extension direction of the support column is parallel to the long axis of its projection shape. If the projection of the support column structure in the thickness direction of the display panel is an irregular shape, then the extension direction of the support column is parallel to the longest side of its projection shape.

[0277] Fig.41 is a schematic diagram of another display panel provided by an embodiment of the present utility model, such as Fig.41 The optional display panel shown includes: a substrate 101; a pixel defining layer 110 located on one side of the substrate 101 and a plurality of light-emitting elements 103, the pixel defining layer 110 includes a plurality of pixel openings, the light-emitting element 103 includes a first electrode 105, a second electrode 107 and a light-emitting layer 106 located between the first electrode 105 and the second electrode 107; the light-emitting element 103 includes a first sub-pixel 11, a second sub-pixel 12 and a third sub-pixel 13; for at least one of the first sub-pixel 11 and the second sub-pixel 12, the shape of the first electrode 105 is substantially the same as the shape of the corresponding pixel opening. Fig.42 yes Fig.41 Schematic diagram of the first electrode and the pixel opening. It can be understood that there are also multiple different film layers between the substrate 101 and the pixel defining layer 102, such as multiple metal layers, interlayer insulating layers, buffer layers, dielectric layers, planarization layers, etc. The film layer structure between the substrate 101 and the pixel defining layer 102 is not specifically described here. The substrate 101 can be regarded as a collection of multi-film layer structures that drive the light-emitting element 103 to work.

[0278] In this embodiment, a thin film transistor array (not shown) is disposed on the substrate 101 of the display panel. The pixel defining layer 110 is an insulating layer, specifically located on one side of the substrate 101. The pixel defining layer 110 has a plurality of pixel openings, and the area corresponding to the lower opening in the pixel opening is the light-emitting area of ​​the sub-pixel, and the area outside the pixel opening of the pixel defining layer 110 is a non-opening area that can be used to set a support column.

[0279] The pixel defining layer 110 and the plurality of light emitting elements 103 are located on the same side of the substrate 101. The first electrode 105 in the light emitting element 103 may be an anode, and the second electrode 107 may be a cathode, but is not limited thereto. In other embodiments, the positions of the anode and the cathode are not limited thereto. The light emitting layer 106 is located between the first electrode 105 and the second electrode 107. The light emitting layer 106 of the first sub-pixel 11 may be configured to include a red light emitting material, the light emitting layer 106 of the second sub-pixel 12 may be configured to include a blue light emitting material, and the light emitting layer 106 of the third sub-pixel 13 may be configured to include a green light emitting material, but is not limited thereto.

[0280] It can be understood that a first functional layer may be further included between the first electrode 105 and the light-emitting layer 106 in the light-emitting element 103, and a second functional layer may be further included between the second electrode 107 and the light-emitting layer 106. If the first electrode 105 is an anode and the second electrode 107 is a cathode, the first functional layer may include a hole injection layer and a hole transport layer, and the second functional layer may include an electron transport layer and a hole blocking layer. The film structure of the display panel also includes a protective layer on the side of the second electrode 107 away from the first electrode 105, etc., which will not be specifically illustrated and described.

[0281] Combination Fig.41 and Fig.42 As shown, the shape of the first electrode 105 is substantially the same as the shape of the corresponding pixel opening.

[0282] Specifically, the shape of the first electrode 105 of the first sub-pixel 11 is substantially the same as the shape of the opening of the first sub-pixel 11, that is, the shape of the first electrode 105 is designed so that the opening of the first sub-pixel 11 meets the requirements. The opening corresponding to the first sub-pixel 11 is a pixel opening 111, wherein the pixel opening 111 includes a lower opening area 111b (light-emitting area) and an upper opening area 111a, and the size of the upper opening 111a is larger than that of the lower opening 111b, but the contours of the two are substantially the same. In order to prevent the silver metal in the first electrode 105 (usually an ITO-Ag-ITO structure) from being corroded and damaging the first electrode 105, the area of ​​the first electrode 105 is usually set larger than that of the lower opening area 111b, but the contours of the two are substantially the same. For example, the first electrode 105 of the first sub-pixel 11 includes a third sub-side 105c corresponding to the third side of the first sub-pixel 11, and the shape, curvature, etc. of the third sub-side 105c can be substantially the same as the third side of the first sub-pixel 11, and the third side of the opening of the first sub-pixel 11 formed subsequently meets the design requirements.

[0283] Similarly, the shape of the first electrode 105 of the second sub-pixel 12 is substantially the same as the shape of the opening of the second sub-pixel 12. The opening corresponding to the second sub-pixel 12 is a pixel opening 112, wherein the pixel opening 112 includes a lower opening area 112b (light-emitting area) and an upper opening area 112a, and the upper opening 111a is larger than the lower opening 111b, but the contours of the two are substantially the same. The shape of the first electrode 105 of the second sub-pixel 12 is substantially the same as the shape of the lower opening area 112b of the corresponding pixel opening 112.

[0284] Similarly, the shape of the first electrode 105 of the third sub-pixel 13 is substantially the same as the shape of the opening of the third sub-pixel 13. The opening corresponding to the third sub-pixel 13 is the pixel opening 113, wherein the pixel opening 113 includes a lower opening area 113b (luminous area) and an upper opening area 113a, and the upper opening 111a is larger than the lower opening 111b, but the contours of the two are substantially the same. The shape of the first electrode 105 of the third sub-pixel 13 is substantially the same as the shape of the lower opening area 113b of the corresponding pixel opening 113. It should be noted that Fig.42 In the figure, the opening corresponding to the third sub-pixel 13 is a rounded rectangle, that is, a regular pattern as defined above, whose center coincides with the center of gravity.

[0285] In order to increase the screen-to-body ratio of the display panel, optical collection elements (such as cameras, fingerprint recognition sensors, and other devices that work using optical signals) are usually set at a position overlapping with the display area. Since the first electrode 105 is usually opaque, the shape of the first electrode 105 in the embodiment of the utility model is set to be roughly the same as the shape of the corresponding pixel opening (lower opening area), so that more light can pass through the display panel, thereby improving the transmittance of the display panel and ensuring the optical signal collection effect. In addition, the shape of the first electrode 105 is roughly the same as the shape of the corresponding pixel opening, that is, the first electrode may include a curved edge, such as Fig.43 When the optical collection element is arranged at a position overlapping with the display area, the boundary line between the opaque first electrode 105 and the surrounding light-transmitting area is an arc line, which is equivalent to a plurality of straight lines extending in different directions, and the light energy is distributed in a plurality of different directions, thereby weakening the diffraction phenomenon and improving the optical signal collection effect.

[0286] The shape of the first electrode is designed so that the corresponding pixel opening meets the requirements. Fig.42 , a connection via hole of the first electrode 105 of a first sub-pixel 11, two connection via holes of the first electrodes 105 of the third sub-pixels 13, and a connection via hole of the first electrode 105 of a second sub-pixel 12 are shown. In which, along the S2 direction, the connection via holes of the first electrodes 105 of the adjacent first sub-pixels 11 and third sub-pixels 13 can be arranged adjacent to each other; along the S2 direction, the connection via holes of the first electrodes 105 of the adjacent second sub-pixels 12 and third sub-pixels 13 can be arranged adjacent to each other.

[0287] It should be noted that due to external factors such as equipment and process, a rounded corner is naturally formed at the right angle of the lower opening area of ​​the sub-pixel. The radius of the rounded corner caused by the process is generally about 1 to 3 microns. The subsequent embodiments describe the formation of the rounded corner in detail. In this embodiment, the shape of the first electrode 105 is roughly the same as the shape of the corresponding pixel opening. The first electrode 105 can also be designed according to the rounded corner of the lower opening area of ​​the sub-pixel, that is, the right angle of the first electrode 105 is chamfered to form a rounded corner, and the shape of the first electrode 105 can be a rounded rectangle.

[0288] An optional display panel includes: a substrate; a pixel defining layer located on one side of the substrate and a plurality of light-emitting elements, the pixel defining layer includes a plurality of pixel openings, the light-emitting element includes a first electrode, a second electrode and a light-emitting layer located between the first electrode and the second electrode; the light-emitting element includes a first sub-pixel, a second sub-pixel and a third sub-pixel; in at least one of the first sub-pixel and the second sub-pixel, the first electrode includes a first sub-edge corresponding to the first edge, a second sub-edge corresponding to the second edge and a third sub-edge corresponding to the third edge, the third sub-edge connecting the first sub-edge and the second sub-edge on the same side; the vertical distance from the intersection of the first edge and the first sub-segment to the third sub-edge is F1, the shortest distance between the third edge and the third sub-edge is F2, and 2≤F1 / F2≤8.

[0289] Fig.43 is a schematic diagram of another sub-pixel provided by an embodiment of the present utility model, and the first sub-pixel and the second sub-pixel can each independently select the sub-pixel. Fig.43 The first electrode 105 of the sub-pixel shown includes a first sub-edge 105a corresponding to the first edge 21, a second sub-edge 105b corresponding to the second edge 22, and a third sub-edge 105c corresponding to the third edge 23. The third sub-edge 105c is located on the same side of the first sub-edge 105a and the second sub-edge 105b and connects the first sub-edge 105a and the second sub-edge 105b. The first sub-edge 105a, the second sub-edge 105b and the third sub-edge 105c can all be straight line segments, but are not limited to this. The third sub-edge can also be an arc segment, etc.

[0290] The vertical distance from the intersection point P2 of the first side 21 and the first sub-segment 23a to the third sub-side 105c is F1, the shortest distance between the third side 23 and the third sub-side 105c is F2, and F1 and F2 satisfy 2≤F1 / F2≤8, that is, the size of the first electrode 105 of the sub-pixel is larger than the size of the opening area of ​​the sub-pixel, and the shape (or outline) of the first electrode 105 is different from the shape (or outline) of the opening area of ​​the sub-pixel. In addition, when the third sub-side 105c of the first electrode 105 is a straight line segment, it is equivalent to that the first electrode 105 is not chamfered.

[0291] Fig.44 is a schematic diagram of another display panel provided by an embodiment of the present utility model, such as Fig.44 As shown, the third side of the opening area of ​​the first sub-pixel 11 can be composed of a plurality of sub-segments connected, and the shape of the first electrode 105 of the first sub-pixel 11 can be a rectangular shape, and the first electrode 105 is connected to the corresponding signal line through the via 105d. The third side of the opening area of ​​the second sub-pixel 12 can be composed of a plurality of sub-segments connected, and the shape of the first electrode 105 of the second sub-pixel 12 can be a rectangular shape, and the first electrode 105 is connected to the corresponding signal line through the via. The shape of the opening area of ​​the third sub-pixel 13 can be a rectangle, and the shape of the first electrode 105 of the third sub-pixel 13 can be a rectangular shape, and the first electrode 105 is connected to the corresponding signal line through the via. Along the thickness direction of the display panel, the opening area of ​​the sub-pixel is located inside the shape of the corresponding first electrode. The first electrode can be the anode of the light-emitting element.

[0292] The display panel generally includes pixel circuits arranged in an array, and the pixel circuits include metal connecting portions connected to different positions, and the metal connecting portions are located at fixed positions in the pixel circuits, so that the array arrangement of the metal connecting portions is the same as the array arrangement of the pixel circuits. On this basis, since the first electrodes (such as anodes) corresponding to the pixel circuits in the same row are not arranged in a row (or a column) along the row direction (or column direction), the areas of the metal connecting portions covered by different first electrodes may be different, resulting in differences in the coupling capacitance at the nodes in the pixel circuits (such as the nodes connected to the gate of the driving transistor). The area of ​​the first electrode 105 is set to be larger than that of the lower opening area 111b, and F1 and F2 satisfy 2≤F1 / F2≤8, or further, the first electrode 105 also includes a protrusion 105-1, and the protrusion 105-1 can at least partially overlap with the metal connecting portion in the thickness direction of the display panel, thereby reducing the difference in the overlapping area between the metal connecting portion and the first electrode 105 in different pixel circuits; thereby reducing the difference in coupling capacitance caused by the difference in overlapping area, which is beneficial to improving the dark line problem caused by uneven luminous brightness and improving the quality of the display image.

[0293] An optional display panel includes: a substrate; a pixel defining layer located on one side of the substrate and a plurality of light-emitting elements, the pixel defining layer including a plurality of pixel openings, the light-emitting element including a first electrode, a second electrode and a light-emitting layer located between the first electrode and the second electrode; the light-emitting element including a first sub-pixel, a second sub-pixel and a third sub-pixel; for at least one of the first sub-pixel and the second sub-pixel, the shape of the light-emitting layer is substantially the same as the shape of the corresponding pixel opening.

[0294] Fig.45 is a schematic diagram of another sub-pixel provided by an embodiment of the present utility model, and the first sub-pixel and the second sub-pixel can each independently select the sub-pixel. Fig.45As shown, taking the sub-pixel as the first sub-pixel 11 as an example, the shape of the light-emitting layer 106 of the first sub-pixel 11 is substantially the same as the shape of the lower opening area 111b of the first sub-pixel 11. Specifically, after forming the first electrode 105 of the light-emitting element, a pixel defining layer is formed, and then an opening of the pixel defining layer is formed, wherein one side of the shape of the lower opening area 111b of the first sub-pixel 11 is formed by connecting a plurality of sub-segments, and then the light-emitting layer 106 is evaporated. The light-emitting layer 106 is formed by evaporation of a fine metal mask (FMM). The size of the fine metal mask is generally large and cannot be processed and formed in one piece. It is usually prepared by a strip mask (FMM sheet, also known as a mask strip) process, and each mask is provided with a mask opening area, and the mask opening area is provided with a mask opening for evaporation. The shape of the light-emitting layer is roughly the same as the shape of the corresponding pixel opening, that is, if one side of the lower opening area is a straight line segment, the side of the light-emitting layer corresponding to the side is also a straight line segment; if one side of the lower opening area is an arc segment, the side of the light-emitting layer corresponding to the side is also an arc segment. In other words, at different positions, the minimum spacing between the lower opening area and the light-emitting layer is roughly equal (the difference is within ±20%). The shape of the light-emitting layer is roughly the same as the shape of the corresponding pixel opening, which is equivalent to the mask opening being roughly the same as the opening shape of the lower opening area 111b. In the production process of the display panel, it is necessary to select a suitable mask opening according to the shape and size of the light-emitting layer. When the light-emitting layer to be evaporated is a rectangle or a rounded rectangle, the mask opening can be a rectangle or a rounded rectangle. Due to process conditions, when the mask opening is a rectangle, the shape of the light-emitting layer actually formed may be a rounded rectangle.

[0295] However, the mask plate will deform due to wrinkles caused by stretching, welding and other processes, resulting in a misalignment between the mask opening and the pixel opening of the pixel definition layer, which directly affects the position accuracy of the sub-pixels after evaporation, causing display abnormalities such as color spots and color deviation. Setting the shape of the light-emitting layer to be roughly the same as the shape of the corresponding pixel opening can increase the rib width of the mask plate as much as possible, thereby avoiding deformation of the mask plate during use, thereby ensuring the alignment accuracy during evaporation and improving product yield and display effect.

[0296] It is understandable that when evaporating the light-emitting layer, the mask openings of the first sub-pixel, the second sub-pixel and the third sub-pixel do not overlap, but in actual products, the light-emitting layer materials of sub-pixels of different colors may overlap in the non-opening area due to process conditions.

[0297] No matter how the lower opening area of ​​the sub-pixel changes, the area of ​​the light-emitting layer is larger than the area of ​​the lower opening area of ​​the sub-pixel, and the light-emitting layer needs to completely cover the lower opening area of ​​the sub-pixel. In addition, the area of ​​the first electrode is usually larger than the area of ​​the lower opening area of ​​the sub-pixel.

[0298] An optional display panel includes: a substrate; a pixel defining layer located on one side of the substrate and a plurality of light-emitting elements, the pixel defining layer includes a plurality of pixel openings, the light-emitting element includes a first electrode, a second electrode and a light-emitting layer located between the first electrode and the second electrode; the light-emitting element includes a first sub-pixel, a second sub-pixel and a third sub-pixel; in at least one of the first sub-pixel and the second sub-pixel, the light-emitting layer includes a first boundary corresponding to the first side, a second boundary corresponding to the second side and a third boundary corresponding to the third side, the third boundary connects the first boundary and the second boundary on the same side; the vertical distance from the intersection of the first side and the first sub-segment to the third boundary is F3, the shortest distance between the third side and the third boundary is F4, 1≤F3 / F4≤4.

[0299] Fig.46 is a schematic diagram of another sub-pixel provided by an embodiment of the present utility model, and the first sub-pixel and the second sub-pixel can each independently select the sub-pixel. Fig.46 The light-emitting layer 106 of the sub-pixel shown includes a first boundary 106a corresponding to the first side 21, a second boundary 106b corresponding to the second side 22, and a third boundary 106c corresponding to the third side 23, and the third boundary 106c connects the same side of the first boundary 106a and the second boundary 106b; the vertical distance from the intersection point P2 of the first side 21 and the first sub-segment 23a to the third boundary 106c is F3, and the shortest distance between the third side 23 and the third boundary 106c is F4, 1≤F3 / F4≤4. The first boundary 106a, the second boundary 106b, and the third boundary 106c can all be straight line segments, but are not limited thereto, and the third boundary can also be an arc segment, etc.

[0300] The evaporation process is to place the evaporation material in a vacuum environment, and evaporate or sublimate the evaporation material by heating. The molecules of the evaporated evaporation material are attached to the substrate to be evaporated through the mask opening. However, due to the temperature rise of the environment, the expansion rate between the substrate carrying the first electrode and the pixel definition layer and the mask is different, which leads to a great deviation between the evaporation material and the pixel definition layer opening that it should cover after evaporation in some areas. In the embodiment of the utility model, the evaporation area of ​​the light-emitting layer 106 of the sub-pixel is larger than the opening shape of the sub-pixel, and the vertical distance from the intersection point P2 of the first side 21 and the first sub-segment 23a to the third boundary 106c is F3, and the shortest distance between the third side 23 and the third boundary 106c is F4, and F3 and F4 meet 1≤F3 / F4≤4, which can ensure that the pixel definition layer opening can be covered by the corresponding evaporation material, and can also avoid the overlap of two light-emitting materials in the same pixel opening due to the mask opening being too large and the position deviation, thereby improving the product yield and display effect.

[0301] It should be noted that the shape of the pixel opening of the pixel defining layer may be different from the shape of the light emitting layer, so the center of gravity of the pixel opening of the pixel defining layer may not coincide with the center of gravity of the corresponding light emitting layer.

[0302] In the process of manufacturing the display panel, it is necessary to select a suitable mask opening according to the shape and size of the light-emitting layer. When the light-emitting layer to be evaporated is a rectangle or a rounded rectangle, the mask opening can be a rectangle or a rounded rectangle. Due to process conditions, when the mask opening is a rectangle, the shape of the light-emitting layer actually formed may be a rounded rectangle. Regardless of how the lower opening area of ​​the sub-pixel changes, the area of ​​the light-emitting layer is larger than the area of ​​the lower opening area of ​​the sub-pixel, and the light-emitting layer needs to completely cover the lower opening area of ​​the sub-pixel.

[0303] Optionally, both the first sub-pixel and the second sub-pixel also include a fourth side opposite to the third side, and the fourth side connects the same side of the first side and the second side; both the first sub-pixel and the second sub-pixel also include a first arc segment and a second arc segment, the first arc segment connects the first side and the fourth side, and the second arc segment connects the second side and the fourth side; the radius Rb of the virtual circle corresponding to the first arc segment is ≤3um, and the radius Rc of the virtual circle corresponding to the second arc segment is ≤3um.

[0304] Fig.47 is a schematic diagram of another sub-pixel provided by an embodiment of the present utility model, and the first sub-pixel and the second sub-pixel can each independently select the sub-pixel. Fig.47 The sub-pixel shown also includes a fourth side 24 opposite to the third side 23, and the fourth side 24 connects the same side of the first side 21 and the second side 22; the sub-pixel also includes a first arc segment 11k and a second arc segment 11m, the first arc segment 11k connects the first side 21 and the fourth side 24, and the second arc segment 11m connects the second side 22 and the fourth side 24; the radius Rb≤3um of the virtual circle 18k corresponding to the first arc segment 11k, and the radius Rc≤3um of the virtual circle 18m corresponding to the second arc segment 11m.

[0305] Specifically, an inscribed circle 18k of the sub-pixel can be roughly determined according to the endpoint P11 of the first side 21 and the endpoint P12 of the fourth side 24, and the arc from the point P11 to P12 on the inscribed circle 18k is determined as the first arc segment 11k connecting the first side 21 and the fourth side 24. The first side 21 and the fourth side 24 may intersect at a right angle vertex (such as Figure 2 As shown in FIG. 1 , due to process manufacturing conditions, the first side 21 and the fourth side 24 are connected by the first arc segment 11k. The radius Rb of the virtual circle 18k is ≤ 3um, for example, Rb is 1um, 1.9um, 2.8um, etc. If the radius Rb of the virtual circle 18k is 0, the first side 21 of the straight line segment is directly connected to the fourth side 24 of the straight line segment.

[0306] An inscribed circle 18m of the sub-pixel is determined according to the endpoint P14 of the second side 22 and the endpoint P13 of the fourth side 24, and the arc from the point P13 to P14 on the inscribed circle 18m is determined as the second arc segment 11m connecting the second side 22 and the fourth side 24. The second side 22 and the fourth side 24 may intersect at a right angle vertex (such as Figure 2 As shown in FIG. 1 , due to process manufacturing conditions, the second side 22 and the fourth side 24 are connected by the second arc segment 11m. The radius Rc of the virtual circle 18m is ≤3um, for example, Rc is 1um, 1.9um, 2.8um, etc. If the radius Rc of the virtual circle 18m is 0, the second side 22 of the straight line segment is directly connected to the fourth side 24 of the straight line segment.

[0307] The radius Rc of the virtual circle 18m and the radius Rb of the virtual circle 18k may be equal to or different from each other.

[0308] It should be noted that the first arc segment and the second arc segment of the sub-pixel are only examples. In practice, the first arc segment and the second arc segment may not be formed by direct chamfering, but may be naturally rounded at the right angle position of the sub-pixel opening due to external factors such as equipment and process. The radius of the rounded corner caused by the process is generally about 1 to 3 microns.

[0309] Fig.48 is a schematic diagram of another display panel provided by an embodiment of the present utility model, such as Fig.48 As shown, the optional display panel includes: a substrate 101; a pixel defining layer 110 located on one side of the substrate 101 and a plurality of light emitting elements 103, the pixel defining layer 110 includes a pixel opening 110a and a levee 110b, the pixel opening 110a is provided with the light emitting element 103; the levee 110b includes a side surface 102a and a bottom surface 102b located on one side of the substrate 101, and an angle θ formed between the side surface 102a and the bottom surface 102b is an acute angle; wherein the angle θ varies according to the position.

[0310] In this embodiment, the pixel defining layer 110 includes a plurality of pixel openings 110a and a bank 110b. For one pixel opening 110a, the bank 110b surrounds the pixel opening 110a. In the thickness direction of the display panel, the pixel opening 110a includes an upper opening and a lower opening, and the light emitting layer 106 at least partially covers the lower opening of the pixel opening 110a. The cross-sectional shape of the pixel opening 110a along the thickness direction of the display panel is an inverted trapezoid, that is, the upper opening of the pixel opening 110a is larger than the lower opening of the pixel opening 110a.

[0311] The bank 110b includes a top surface 102c, a bottom surface 102b, and a side surface 102a connecting the top surface 102c and the bottom surface 102b. Based on the inverted trapezoidal shape of the pixel opening 110a, the cross-sectional shape of the bank 110b along the thickness direction of the display panel is a regular trapezoid, so the angle θ between the side surface 102a and the bottom surface 102b of the bank 110b is an acute angle.

[0312] It should be noted that Fig.48 The side surface 102a is roughly a plane for illustration, and in some embodiments, the side surface 102a can be a curved surface. When the side surface 102a is a curved surface, the maximum angle formed between the side surface 102a and the bottom surface 102b toward the inside of the bank 110b is the above-mentioned angle θ. It can be understood that, for a point on the curved surface, the angle formed by the tangent line of the point and the bottom surface 102b toward the inside of the bank 110b is the angle between the side surface 102a and the bottom surface 102b at the position.

[0313] It is understandable that the sub-pixel includes multiple edges, each edge includes multiple points, and the angle formed between the side 102a and the bottom surface 102b is not completely equal at each position. The reason is that when forming the pixel definition layer opening, it is necessary to perform exposure display operation through the mask; when exposed, the light will form interference fringes. When the light passes through the center position of the straight edge of the mask, the interference fringes formed are the sparsest, and the corresponding exposure amount is the smallest; and the closer to the intersection of the two edges, the denser the interference fringes formed, and the greater the corresponding exposure amount. The greater the exposure amount, the less the photoresist residues such as the corresponding position, the more etched during development, and the greater the angle of the pixel definition layer formed (the maximum angle formed between the side 102a and the bottom surface 102b toward the inside of the embankment 110b); conversely, the smaller the angle of the pixel definition layer formed.

[0314] It is understandable that the included angles of the pixel definition layers corresponding to the first sub-pixel 11 , the second sub-pixel 12 and the third sub-pixel 13 at the same position (such as the midpoint of the third side 23 ) may also be different.

[0315] The inventor of the utility model has found that the angle of the pixel definition layer affects the light output efficiency of the display panel and the amount of light output at different viewing angles. Moreover, at a wide viewing angle, the pixel definition layer has different effects on the brightness attenuation of light of different wavelengths, resulting in different attenuation degrees of the brightness of the two colors of light as the viewing angle changes. Specifically, the brightness attenuation degree of light with a long wavelength is greater than the brightness attenuation degree of light with a short wavelength, which ultimately causes the image displayed by the display panel at a wide viewing angle to have color shift at a wide viewing angle. Therefore, for sub-pixels of the same color and / or sub-pixels of different colors, the angle θ is set differently according to different positions, so that the light output of the display panel at normal viewing angles and wide viewing angles, as well as the color shift, can be flexibly adjusted.

[0316] The optional angle θ includes an angle θa corresponding to the first side and an angle θb corresponding to the third side, θb≥θa.

[0317] Combination Figure 2 and Fig.48 As shown, the area surrounded by the first side 21, the second side 22, the third side 23 and the fourth side 24 of the sub-pixel is the lower opening of the sub-pixel, so the edge of the bottom surface 102b of the bank 110b overlaps with the first side 21, the second side 22, the third side 23 and the fourth side 24 of the sub-pixel. The first side 21 of the sub-pixel is a straight line segment, and θa is the angle between the side surface 102a of the bank 110b and the bottom surface 102b corresponding to the first side 21. The third side 23 of the sub-pixel is composed of a plurality of sub-segments, and θb is the angle between the side surface 102a of the bank 110b and the bottom surface 102b corresponding to the third side 23. It is designed that θb is greater than or equal to θa.

[0318] Taking the first sub-pixel 11 as an example, specifically, the greater the curvature of the side of the first sub-pixel 11, the greater the angle between the side 102a of the bank 110b and the side. The first side 21 of the first sub-pixel 11 is a straight line segment, and the third side 23 is composed of a plurality of sub-segments. Compared with the first side 21, the third side 23 has a greater curvature. The angle θb between the side 102a of the bank 110b of the first sub-pixel 11 and the third side 23 is greater than the angle θa between the side 102a of the bank 110b of the first sub-pixel 11 and the first side 21. Because when light passes through the edge position with a larger curvature of the mask, the interference fringes formed are denser and the corresponding exposure amount is larger. The greater the exposure amount, the less the residues such as photoresist at the corresponding position, the more etched during development, and the greater the angle of the pixel definition layer formed.

[0319] In one embodiment, in combination Fig.47 and Fig.48 , the third side 23 is an arc side, the fourth side 24 is a straight side, the angle between the side surface 102a and the bottom surface 102b at the midpoint P1 of the third side 23 is θ1, the angle at the midpoint P15 of the fourth side 24 is θ2, the angle at the midpoint of the first sub-segment 23a is θ3, the angle at the midpoint of the second sub-segment 23b is θ4, the angle at the midpoint of the first arc segment 11k is θ5, and the angle at the midpoint of the second arc segment 11m is θ6. Within the range of process error and measurement error, θ1, θ2, θ3 and θ4 are approximately equal; θ5 and θ6 are approximately equal, and θ5 is greater than θ1.

[0320] Specifically, the third side 23 is an arc side, and its corresponding curvature radius is relatively large. The first side 21, the second side 22 and the fourth side 24 are straight sides. Under existing equipment and process conditions, when the pixel definition layer is exposed through the mask, the exposure amount of the third side 23 and the midpoints of the first side 21, the second side 22 and the fourth side 24 are approximately equal, so the angles of the pixel definition layer formed after the development and etching process are approximately equal.

[0321] As for the connection between the fourth side 24 and the first side 21 (or the third side 23), the two may be directly connected to form a Figure 2 It is also possible that the first arc segment 11k (or the second arc segment 11m) is connected to form a Fig.47 It should be noted that due to the influence of external factors such as equipment and process, even if the initial design is a right angle ( Figure 2 The right angle between the midpoint P4 and the point P5), but the final result may still be a rounded corner ( Fig.47 The first arc segment 11k and the second arc segment 11m correspond to each other). Figure 2 and Fig.47 Under the existing equipment and process conditions, when the pixel definition layer is exposed through the mask, interference fringes will be generated when the light passes through the mask. The closer to the connection between the fourth side 24 and the first side 21 (or the third side 23), the denser the interference fringes are. The greater the exposure, the less the photoresist residues at the corresponding position, the more etching during development, and the larger the angle of the pixel definition layer. Therefore, the angle θ5 corresponding to the midpoint of the first arc segment 11k is greater than the angle θ1 corresponding to the midpoint P1 of the third side 23.

[0322] Fig.49 is a schematic diagram of another display panel provided by an embodiment of the utility model, Fig.50 yes Fig.49 Schematic diagram of the touch electrode layer.

[0325] An organic light-emitting device layer 203 is provided on the side of the thin film transistor array layer 202 facing away from the substrate 201. The organic light-emitting device layer 203 includes a plurality of organic light-emitting devices, wherein the organic light-emitting devices include red organic light-emitting devices, green organic light-emitting devices, and blue organic light-emitting devices. The light-emitting layer of the red organic light-emitting device includes a red organic light-emitting material, the light-emitting layer of the green organic light-emitting device includes a green organic light-emitting material, and the light-emitting layer of the blue organic light-emitting device includes a blue organic light-emitting material.

[0326] A thin film encapsulation layer 204 is disposed on the side of the organic light-emitting device layer 203 facing away from the substrate 201 . The thin film encapsulation layer 204 is used for encapsulation to prevent external water vapor, impurities, etc. from entering the organic device layer 203 .

[0327] A touch electrode layer 205 is provided on the side of the thin film encapsulation layer 204 facing away from the substrate 201. The touch electrode layer 205 includes a plurality of metal traces, wherein the extension directions of the metal traces 205a and the metal traces 205b intersect. The metal traces 205a and the metal traces 205b may be provided in the same layer insulated, or the metal traces 205a and the metal traces 205b may be provided in a stacked insulated manner. The plurality of metal traces 205a and the plurality of metal traces 205b intersect, and a plurality of meshes 205c may be defined in the thickness direction of the display panel, and the thickness direction of the display panel is perpendicular to the plane where the substrate 201 is located. In the direction perpendicular to the plane where the substrate 201 is located, at least one mesh 205c surrounds at least one sub-pixel, and the touch electrode layer 205 located on the side of the organic light-emitting device layer 203 facing away from the substrate 201 will not block the sub-pixel and will not affect the light emission of the sub-pixel.

[0328] In this embodiment, the touch electrode layer 205 is disposed on the side of the thin film encapsulation layer 204 facing away from the substrate 201. The first sub-pixel 11_1, the first sub-pixel 11_2, the first sub-pixel 11_3, and the first sub-pixel 11_4 are four adjacent first sub-pixels 11, and the four adjacent first sub-pixels 11 constitute the minimum repeating unit of the first sub-pixel. The second sub-pixel 12_1, the second sub-pixel 12_2, the second sub-pixel 12_3, and the second sub-pixel 12_4 are four adjacent second sub-pixels 12, and the four adjacent second sub-pixels 12 constitute the minimum repeating unit of the second sub-pixel.

[0329] refer to Figure 2 , Fig.49 and Fig.50For a single first sub-pixel, taking the first sub-pixel 11_2 as an example, the minimum distance from the first sub-segment of the first sub-pixel 11_2 to the intersection of the adjacent metal traces is equal to the minimum distance from the second sub-segment to the intersection of the adjacent metal traces, so the light output at the corresponding positions of the first sub-segment and the second sub-segment is blocked by the metal trace 205 at substantially the same angle, thereby there is no difference in light output. In other words, when the first sub-pixel 11_2 is designed to be axisymmetric, the distances from the corresponding positions of the two symmetrical parts to the metal traces are equal, and when the human eye observes the display panel from the fourth direction S4 and the direction opposite to the fourth direction S4, the size of the light-emitting area of ​​the first sub-pixel 11_2 observed is consistent, thereby reducing the difference in the displayed images, improving the color shift phenomenon, and enhancing the display quality. For the minimum repeating unit of the first sub-pixel, the minimum distance from the first side of the first sub-pixel 11_1 to the adjacent metal routing is equal to the minimum distance from the second side of the first sub-pixel 11_1 to the adjacent metal routing, the minimum distance from the first side of the first sub-pixel 11_2 to the adjacent metal routing is equal to the minimum distance from the second side of the first sub-pixel 11_2 to the adjacent metal routing, the minimum distance from the first side of the first sub-pixel 11_3 to the adjacent metal routing is equal to the minimum distance from the second side of the first sub-pixel 11_3 to the adjacent metal routing, and the minimum distance from the first side of the first sub-pixel 11_4 to the adjacent metal routing is equal to the minimum distance from the second side of the first sub-pixel 11_4 to the adjacent metal routing. The minimum distance from the third side of the first sub-pixel 11_1 to the adjacent metal wiring is greater than the minimum distance from the second side of the first sub-pixel 11_1 to the adjacent metal wiring, the minimum distance from the third side of the first sub-pixel 11_2 to the adjacent metal wiring is greater than the minimum distance from the second side of the first sub-pixel 11_2 to the adjacent metal wiring, the minimum distance from the third side of the first sub-pixel 11_3 to the adjacent metal wiring is greater than the minimum distance from the second side of the first sub-pixel 11_3 to the adjacent metal wiring, and the minimum distance from the third side of the first sub-pixel 11_4 to the adjacent metal wiring is greater than the minimum distance from the second side of the first sub-pixel 11_4 to the adjacent metal wiring. In the implementation of the utility model, within the minimum repeating unit of the first sub-pixel, the protrusions of the four first sub-pixels have different directions on the plane, and when the human eye observes the display panel from the first to the fourth direction or the opposite direction, the size of the observed light-emitting area is consistent, thereby reducing the difference in the displayed picture, improving the color shift phenomenon, and improving the display quality.

[0330] Similarly, reference Figure 2 , Fig.49 and Fig.50For a single first sub-pixel, taking the first sub-pixel 12_2 as an example, the minimum distance from the first sub-segment of the first sub-pixel 12_2 to the intersection of the adjacent metal traces is equal to the minimum distance from the second sub-segment to the intersection of the adjacent metal traces, so the light output at the corresponding positions of the first sub-segment and the second sub-segment is blocked by the metal trace 205 at substantially the same angle, thereby no difference in light output exists. In other words, when the first sub-pixel 12_2 is designed to be axisymmetric, the distances from the corresponding positions of the two symmetrical parts to the metal traces are equal, and when the human eye observes the display panel from the fourth direction S4 and the direction opposite to the fourth direction S4, the size of the light-emitting area of ​​the first sub-pixel 12_2 observed is consistent, thereby reducing the difference in the displayed images, improving the color shift phenomenon, and enhancing the display quality. For the minimum repeating unit of the second sub-pixel, the minimum distance from the first side of the second sub-pixel 12_1 to the adjacent metal routing is equal to the minimum distance from the second side of the second sub-pixel 12_1 to the adjacent metal routing, the minimum distance from the first side of the second sub-pixel 12_2 to the adjacent metal routing is equal to the minimum distance from the second side of the second sub-pixel 12_2 to the adjacent metal routing, the minimum distance from the first side of the second sub-pixel 12_3 to the adjacent metal routing is equal to the minimum distance from the second side of the second sub-pixel 12_3 to the adjacent metal routing, and the minimum distance from the first side of the second sub-pixel 12_4 to the adjacent metal routing is equal to the minimum distance from the second side of the second sub-pixel 12_4 to the adjacent metal routing. The minimum distance from the third side of the second sub-pixel 12_1 to the adjacent metal wiring is greater than the minimum distance from the second side of the second sub-pixel 12_1 to the adjacent metal wiring, the minimum distance from the third side of the second sub-pixel 12_2 to the adjacent metal wiring is greater than the minimum distance from the second side of the second sub-pixel 12_2 to the adjacent metal wiring, the minimum distance from the third side of the second sub-pixel 12_3 to the adjacent metal wiring is greater than the minimum distance from the second side of the second sub-pixel 12_3 to the adjacent metal wiring, and the minimum distance from the third side of the second sub-pixel 12_4 to the adjacent metal wiring is greater than the minimum distance from the second side of the second sub-pixel 12_4 to the adjacent metal wiring. In the implementation of the utility model, within the minimum repeating unit of the second sub-pixel, the protrusions of the four second sub-pixels have different directions on the plane, and when the human eye observes the display panel from the first to the fourth direction or the opposite direction, the size of the observed light-emitting area is consistent, thereby reducing the difference in the displayed picture, improving the color shift phenomenon, and improving the display quality.

[0331] It should be noted that the structure of the touch electrode layer is not limited to the figure. In other embodiments, the touch electrode layer may also be a single-layer metal layer or a transparent conductive layer, for example, the transparent conductive layer may include a transparent conductive oxide ITO. But not limited to this. Alternatively, the touch electrode layer may also be a multi-layer metal layer, and the metal layer may have a three-layer structure of titanium / aluminum / titanium. The structure of the touch electrode layer is not specifically limited.

[0332] As described above, the touch electrode layer 205 is located above the side of the thin film encapsulation layer 204 facing away from the substrate 201, and there is no need to set up an external touch structure, which is conducive to the development of thin and narrow-framed display panels, and is also conducive to application in foldable display panels, and is more cost-effective.

[0333] Fig.51 is a schematic diagram of another display panel provided by an embodiment of the utility model, Fig.52 for Fig.51 A partial enlarged schematic diagram of the middle area Qa, see Fig.48 , Fig.51 and Fig.52 As shown, the optional display panel includes: a display area 301 and a non-display area 302 that at least partially surrounds the display area 301; the display area 301 includes a plurality of data lines 303 arranged along a first direction S1 and extending along a second direction S2, and the first direction S1 and the second direction S2 intersect; the display area 301 also includes a substrate 101, a pixel defining layer 110 located on one side of the substrate 101, and a plurality of light-emitting elements 103, the pixel defining layer 110 includes a plurality of pixel openings 110a, the light-emitting element 103 includes a first electrode 105, a second electrode 107, and a light-emitting layer 106 located between the first electrode 105 and the second electrode 107; in a direction perpendicular to the plane where the substrate 101 is located, the first electrodes 105 of the first sub-pixel 11 and the second sub-pixel 12 both overlap with the two data lines 303.

[0334] In this embodiment, the display panel includes a display area 301 and a non-display area 302. A plurality of sub-pixels are arranged in the display area 301, including at least a plurality of first sub-pixels 11, a plurality of second sub-pixels 12, and a plurality of third sub-pixels 13.

[0335] The display area 301 includes a plurality of data lines 303 arranged along a first direction S1 and extending along a second direction S2. A data line 303 is electrically connected to sub-pixels of the same color in a column and provides data signals for the sub-pixels of the same color in the column. The column is parallel to the direction S2.

[0336] As described above, in the first direction S1, the first sub-pixel 11 and the second sub-pixel 12 are arranged alternately. And in the second direction S2, the first sub-pixel 11 and the second sub-pixel 12 are arranged alternately. For the first sub-pixel 11 and the second sub-pixel 12 located in the same column, one data line 303 can provide data signals for the first sub-pixel 11 and the second sub-pixel 12 in the column at the same time. And in the direction perpendicular to the plane where the substrate is located, the first electrode 105 of the first sub-pixel 11 and the two data lines 303 are at least partially overlapped, and the first electrode 105 of the second sub-pixel 12 and the two data lines 303 are at least partially overlapped, that is, the light-emitting area of ​​the first sub-pixel 11 and the light-emitting area of ​​the second sub-pixel 12 are overlapped with the two data lines 303. Such a design is conducive to ensuring the flatness and symmetry of the first electrode 105 of the first sub-pixel 11 and the second sub-pixel 12, and is conducive to improving the color deviation of the viewing angle of the first sub-pixel 11 and the second sub-pixel 12, and improving the display effect.

[0337] For a column of third sub-pixels 13, a data line 303 is electrically connected to a corresponding column of third sub-pixels 13 and provides data signals for the column of third sub-pixels 13. In addition, in a direction perpendicular to the plane where the substrate is located, the first electrode 105 of the third sub-pixel 13 at least partially overlaps with the power supply voltage line VDL, that is, the light-emitting area of ​​the third sub-pixel 13 overlaps with the power supply voltage line VDL. Such a design can ensure the flatness of the first electrode 105, which is conducive to ensuring that the light emitted by the pixel has a balanced optical path, avoiding brightness or chromaticity deviation, and ensuring the display effect of the display panel.

[0338] The display area 301 also includes other circuit structures such as scan lines, etc. The scan lines are used to provide scan signals for a row of sub-pixels, but are not limited thereto. Other structures in the display panel are not described in detail here.

[0340] In this embodiment, the non-display area 302 includes a fan-out area 302a, and the fan-out area 302a is located at the lower side of the display area 301 in the figure. The display area 301 includes a first display area 301a and a second display area 301b, and the second display area 301b is located on the left side of the first display area 301a in the figure, but is not limited thereto. The display area 301 may include one or more second display areas 301b, and two second display areas 301b are shown in the figure.

[0341] The fan-out region 302a includes a plurality of fan-out traces 304, and the display region 301 includes a plurality of data lines 303, which are connected to the fan-out traces 304. As shown in the figure, the plurality of line segments connected to the data lines 303 in the fan-out region 302a are all fan-out traces 304.

[0342] The non-display area 302 further includes a source driving circuit 306 , and the fan-out wiring 304 is connected to the source driving circuit 306 . The source driving circuit 306 provides a data signal to the data line 303 of the display area 301 through the fan-out wiring 304 .

[0343] Specifically, the first display area 301a includes a plurality of sub-pixels and a plurality of data lines 303 driving the plurality of sub-pixels, and the second display area 301b also includes a plurality of sub-pixels and a plurality of data lines 303 driving the plurality of sub-pixels. Each data line 303 located in the second display area 301b is connected to a connecting line 305, and each data line 303 in the second display area 301b is connected to a fan-out line 304 in the non-display area 302 through the connecting line 305 located in the display area 301.

[0344] The connection line 305 includes a first connection line segment 305a extending along the second direction S2 and a second connection line segment 305b extending along the first direction S1; in a direction perpendicular to the plane of the substrate, the first electrodes 105 of the first sub-pixel 11 and the second sub-pixel 12 overlap with the two first connection line segments 305a.

[0345] Each data line 303 in the second display area 301b is led out of the display area 301 through a connecting wire 305. In order to reduce the occupied area of ​​the connecting wire 305 corresponding to the data line 303 in the second display area 301b, the connecting wire 305 can be designed to include a plurality of sub-segments, specifically including a first connecting wire segment 305a extending along the second direction S2 and a second connecting wire segment 305b extending along the first direction S1, and the first connecting wire segment 305a and the second connecting wire segment 305b are connected. The first connecting wire segment 305a extends from the display area 301 to the non-display area 302, so the wiring position of the first connecting wire segment 305a will overlap with the sub-pixel in the first display area 301a.

[0346] In the second direction S2, the first sub-pixel 11 and the second sub-pixel 12 are arranged alternately. In the direction perpendicular to the plane where the substrate is located, the first electrode 105 of the first sub-pixel 11 and the first electrode 105 of the second sub-pixel 12 are also overlapped with the two first connecting line segments 305a, which can reduce the display area space occupied by the connecting line 305, which is conducive to high PPI design. At the same time, the flatness design and symmetry of the first electrode 105 can also be guaranteed, which is conducive to ensuring that the light emitted by the pixel has a balanced optical path, avoiding brightness or chromaticity deviation, and ensuring the display effect of the display panel. Based on the same utility model concept, the utility model embodiment also provides a display device, which includes: any one of the display panels provided in the above-mentioned embodiments.

[0347] Fig.52 is a schematic diagram of a display device provided by an embodiment of the utility model, such as Fig.52 As shown, the display device 1 includes a display panel.

[0351] refer to Figure 2As shown, the first sub-pixel 11 includes a first side 21 and a second side 22 that are parallel and a third side 23 that connects the first side 21 and the second side 22 on the same side, and the first sub-pixel 11 also includes a fourth side 24. The third side 23 includes a first sub-segment 23a and a second sub-segment 23b, the first sub-segment 23a connects the first side 21 and the second sub-segment 23b connects the second side 22. The first side 21 and the second side 22 are both straight line segments. The third side 23 may include only the first sub-segment 23a and the second sub-segment 23b, and the fourth side 24 may be a straight line segment, but is not limited thereto.

[0352] In other embodiments, the third side may be optionally composed of three or more sub-segments connected, that is, the third side includes a first sub-segment, a second sub-segment, and a plurality of sub-segments connected between the first sub-segment and the second sub-segment; or, the fourth side may be optionally composed of two or more sub-segments connected; for any one of the third side and the fourth side, any one of its sub-segments may be an arc segment or a straight line segment.

[0353] The maximum angle between the first side 21 and the first sub-segment 23a toward the second side 22 is α b11 The maximum angle between the second side 22 and the second sub-segment 23b toward the first side 21 is α b12 , 90°<α b11 <180°,90°<α b12 <180°.

[0355] Therefore, reference Figure 1A , Figure 1B , Figure 1C and Fig.19Compared with the prior art, the pixel design in the embodiment of the present application can improve the total aperture ratio (aperture area) of the display panel. Moreover, the relevant process parameters in the present application (such as the minimum aperture spacing between adjacent sub-pixels, FMM rib, etc.) are equal to or better than the prior art. In other words, while ensuring that the minimum aperture spacing between adjacent sub-pixels and the FMM rib width are consistent with the prior art or there is still design redundancy, the total aperture ratio of the present application is larger, and the display effect and display quality are better.

[0356] In this embodiment, the design of the first sub-pixel 11 and the second sub-pixel 12 is adopted, and the aperture ratio of the first sub-pixel and the second sub-pixel can be increased while maintaining consistency with existing relevant process parameters (such as the minimum aperture spacing between adjacent sub-pixels, FMM rib, etc.), thereby improving the overall aperture ratio of the display panel and thus improving the display effect. In addition, compared with the prior art, if the overall aperture ratio of the display panel is kept unchanged, the present application can also increase the distance between the opening areas of the adjacent first sub-pixels and the second sub-pixels, so that the lateral distance between the adjacent first sub-pixels and the second sub-pixels is increased, thereby reducing the leakage current between the adjacent first sub-pixels and the second sub-pixels, thereby improving the pixel stealing problem and improving the display effect.

[0357] Optionally, both the first sub-pixel and the second sub-pixel include corresponding circumscribed virtual parallelograms, the circumscribed virtual parallelograms include a first virtual side, a second virtual side, and a third virtual side connecting the first virtual side and the second virtual side on the same side, the first virtual side partially overlaps with the first side, the second virtual side partially overlaps with the second side, and at least one point of the third side is located on the third virtual side; along the thickness direction of the display panel, the first sub-pixel is located in the corresponding circumscribed virtual parallelogram, and the second sub-pixel is located in the corresponding circumscribed virtual parallelogram; in the direction in which the first sub-pixels and the second sub-pixels are alternately arranged, the center line of the circumscribed virtual parallelogram corresponding to the first sub-pixel and the circumscribed virtual parallelogram corresponding to the second sub-pixel intersects with the third side of at least one of the first sub-pixel and the second sub-pixel.

[0358] Refer to Figure 1 and Figure 2 As shown, the first sub-pixel 11 includes a corresponding circumscribed virtual parallelogram. In FIG1 , the circumscribed virtual parallelogram corresponding to the first sub-pixel 11 is marked as 30a. Along the thickness direction of the display panel, the first sub-pixel 11 is located in the corresponding circumscribed virtual parallelogram 30a. The second sub-pixel 12 includes a corresponding circumscribed virtual parallelogram. Figure 1A The circumscribed virtual parallelogram corresponding to the second sub-pixel 12 is marked as 30b. Along the thickness direction of the display panel, the second sub-pixel 12 is located in the corresponding circumscribed virtual parallelogram 30b.

[0359] refer to Figure 2 As shown, for a sub-pixel and its corresponding circumscribed virtual parallelogram 30, the circumscribed virtual parallelogram 30 includes a first virtual side 31 and a second virtual side 32 arranged in parallel, and a third virtual side 33 and a fourth virtual side 34 arranged in parallel. The first virtual side 31 partially overlaps with the first side 21, wherein at least one point of the first side 21 is located on the first virtual side 31, and other points on the first side 21 are located on the first virtual side 31 or in the circumscribed virtual parallelogram 30; the second virtual side 32 partially overlaps with the second side 22, wherein at least one point of the second side 22 is located on the second virtual side 32, and other points on the second side 22 are located on the second virtual side 32 or in the circumscribed virtual parallelogram 30. At least one point of the third side 23 is located on the third virtual side 33, and other points on the third side 23 are located on the third virtual side 33 or within the circumscribed virtual parallelogram 30; at least one point of the fourth side 24 is located on the fourth virtual side 34, and other points on the fourth side 24 are located on the fourth virtual side 34 or within the circumscribed virtual parallelogram 30.

[0360] In the S1 direction, two adjacent first sub-pixels 11 and second sub-pixels 12 meet at least one of the following conditions: 1) the center line Pa11-Pa12 of the circumscribed virtual parallelogram 30a corresponding to the first sub-pixel 11 and the center line Pa11-Pa12 of the circumscribed virtual parallelogram 30b corresponding to the second sub-pixel 12 intersects the third side of the first sub-pixel 11; 2) the center line Pa11-Pa12 of the circumscribed virtual parallelogram 30a corresponding to the first sub-pixel 11 and the center line 30b of the circumscribed virtual parallelogram 30b corresponding to the second sub-pixel 12 intersects the third side of the second sub-pixel 12. The centroid of the first sub-pixel 11 is Pb11, and the centroid of the second sub-pixel 12 is Pb12.

[0361] In the S2 direction, two adjacent first sub-pixels 11 and second sub-pixels 12 satisfy at least one of the following conditions: 1) the center line Pa11-Pa12 of the circumscribed virtual parallelogram 30a corresponding to the first sub-pixel 11 and the center line Pa11-Pa12 of the circumscribed virtual parallelogram 30b corresponding to the second sub-pixel 12 intersects with the third side of the first sub-pixel 11; 2) the center line Pa11-Pa12 of the circumscribed virtual parallelogram 30a corresponding to the first sub-pixel 11 and the circumscribed virtual parallelogram 30b corresponding to the second sub-pixel 12 intersects with the third side of the second sub-pixel 12.

[0362] The shape of the optional circumscribed virtual parallelogram is a rectangle, a square or a rhombus.

[0363] In this embodiment, the shape of the circumscribed virtual parallelogram may be a parallelogram whose interior angles are not equal to 90°. Alternatively, the shape of the circumscribed virtual parallelogram may be a rectangle or a square whose interior angles are all equal to 90°. Alternatively, the shape of the circumscribed virtual parallelogram may be a rhombus whose at least one interior angle is not equal to 90°. It is not limited thereto.

[0364] The shape of the circumscribed virtual parallelogram corresponding to the first sub-pixel and the shape of the circumscribed virtual parallelogram corresponding to the second sub-pixel may be the same or different, and the same mentioned here means that the virtual shapes of the two sub-pixels can completely overlap by translation, rotation, mirroring, etc. Correspondingly, the different mentioned here means that the sides, inner angles, etc. of the virtual shapes of the two sub-pixels are different.

[0365] Optionally, the first subsegment is connected to the second subsegment and a connection point between the two is located at a third virtual edge, the third virtual edge is tangent to the third edge at the connection point, and both the first subsegment and the second subsegment are arc segments.

[0366] refer to Figure 2 As shown, the third side 23 of the sub-pixel only includes the first sub-segment 23a and the second sub-segment 23b, the third side 23 and the third virtual side 33 are tangent to the connection point P1 of the first sub-segment 23a and the second sub-segment 23b, and the first sub-segment 23a and the second sub-segment 23b are both arc segments. In other embodiments, the first sub-segment and the second sub-segment can be both straight line segments, or one of the first sub-segment and the second sub-segment can be an arc segment and the other can be a straight line segment.

[0367] The first sub-segment and the second sub-segment may be located on the circumference of the same virtual circle. 0.5*La≤Ra≤1.5*La may be selected, wherein the radius of the virtual circle is Ra and the length of the first virtual side is La.

[0368] like Fig.10 As shown, point P2 is selected on the first virtual side 31 of the circumscribed virtual parallelogram 30, point P3 is selected on the second virtual side 32, and point P1 is selected on the third virtual side 33. A unique virtual circle 35 can be determined based on points P2, P3 and P1. The arc segment from P2 to P1 on the circumference of the virtual circle 35 is determined as the first sub-segment 23a and the arc segment from P3 to P1 is determined as the second sub-segment 23b. Based on this, the third side 23 of the sub-pixel can be determined.

[0369] If the radius Ra of the virtual circle 35 is less than 0.5*La, the first subsegment 23a and the second subsegment 23b cannot be obtained simultaneously through the same virtual circle, that is, the first subsegment 23a and the second subsegment 23b cannot be located on the circumference of the same virtual circle. The radius Ra of the virtual circle 35 should be less than or equal to 1.5*La to ensure the spacing between the opening areas of adjacent sub-pixels, thereby effectively reducing leakage current and reducing the problem of stealing brightness.

[0370] Optionally, 0.05*La≤Xa≤0.3*La, wherein the vertical distance from the intersection of the first side and the first subsegment to the third virtual side is the first distance Xa, and the length of the first virtual side is La. Optionally, 0.05*Lb≤Xb≤0.3*Lb, wherein the vertical distance from the intersection of the second side and the second subsegment to the third virtual side is the second distance Xb, and the length of the second virtual side is Lb. Optionally, Xa=Xb.

[0371] In this embodiment, for any one of the first subpixel and the second subpixel, Xa and Xb in the subpixel can be reasonably designed. A differential design can be used, that is, the vertical distance Xa from the intersection of the first side and the first subsegment to the third virtual side is not equal to the vertical distance Xb from the intersection of the second side and the second subsegment to the third virtual side; in other embodiments, Xa=Xb can also be selected.

[0372] The first subsegment is optionally connected to the second subsegment and the connection point between the two is located at the third virtual edge, and the first subsegment and the second subsegment are both straight line segments. The optional third edge also includes a third subsegment on the same side connecting the first subsegment and the second subsegment, and the third subsegment is a straight line segment and partially overlaps with the third virtual edge. The first subsegment and the second subsegment are both arc segments.

[0373] In a sub-pixel, the first sub-segment and the second sub-segment may both be straight line segments, the first sub-segment is connected to the second sub-segment, and in this case the third side is composed of the first sub-segment and the second sub-segment. Alternatively, in a sub-pixel, the first sub-segment and the second sub-segment are connected via the third sub-segment, the third sub-segment is a straight line segment and coincides with a portion of the line segments of the third virtual side, and in this case the third side is composed of the first sub-segment, the third sub-segment and the second sub-segment.

[0374] It can be understood that the third side of the sub-pixel can be formed by connecting two or more sub-segments, and any sub-segment in the third side can be a straight line segment or an arc segment.

[0375] The ratio of the length of the optional third sub-segment to the length of the third virtual edge is 5%-40%. If the ratio of the length of the third sub-segment to the length of the third virtual edge is too large, for example 70%, then the larger the angle between the first sub-segment and the first edge toward the second edge and / or the larger the angle between the second sub-segment and the second edge toward the first edge, the smaller the distance between the opening area of ​​the adjacent first sub-pixel and the second sub-pixel, and the improvement effect on the problem of stealing light is not obvious. Therefore, the ratio of the length of the third sub-segment to the length of the third virtual edge is limited to between 5%-40%, which ensures a larger aperture ratio and can also increase the distance between the opening area of ​​the adjacent first sub-pixel and the second sub-pixel to improve the problem of stealing light.

[0376] The optional first sub-pixel, the second sub-pixel and the third sub-pixel are respectively one of a red sub-pixel, a blue sub-pixel and a green sub-pixel and are different from each other. For example, the first sub-pixel can be a red sub-pixel, the second sub-pixel can be a blue sub-pixel, and the third sub-pixel can be a green sub-pixel. However, it is not limited to this, and the relevant designers can reasonably configure the luminous colors of the first sub-pixel, the second sub-pixel and the third sub-pixel according to the product requirements.
