[0056] The above drawings have shown clear embodiments of the present application, which will be described in more detail later. These drawings and text descriptions are not intended to limit the scope of the present application in any way, but to illustrate the concept of the present application to those skilled in the art by referring to specific embodiments. DETAILED DESCRIPTION

[0057] In order to make the objectives, technical solutions and advantages of the present application clearer, the implementation methods of the present application will be further described in detail below in conjunction with the accompanying drawings.

[0058] A technology for realizing color light emission in display panels is the technology of combining white organic light-emitting diodes (WOLED) with color filter layers. Figure 1 , Figure 1 2 is a schematic diagram of a display panel structure provided by the related art. In the display panel 20, the light emitting device 22 is used to emit white light. The display panel 20 is also provided with a color film layer ( Figure 1 (not shown), the color filter layer can filter the white light, so that different colors of light can be emitted. Therefore, in WOLED technology, multiple light-emitting devices 22 can be designed with the same size. For example, Figure 1 In the display panel 20 shown, the plurality of light emitting devices 22 are arranged in a hexagonal shape, which is denser and can improve the aperture ratio. However, the use of WOLED technology will cause most of the light to be blocked by the color filter layer, resulting in lower brightness.

[0059] Another technology to achieve color luminescence is the red, green and blue pixel side by side (SBS) technology, please refer to Figure 2 , Figure 2It is a structural diagram of another display panel provided by the related art. In the display panel 20, a plurality of light-emitting devices 22 include: a first light-emitting device 22a, a second light-emitting device 22b and a third light-emitting device 22c that emit light of different colors. The three light-emitting devices 22 can emit light independently, thereby improving the brightness and reducing power consumption. Exemplarily, SBS technology helps virtual reality (VR) devices and augmented reality (AR) devices to extend the use time and reduce the weight of the devices. However, the luminous efficiency and lifespan of the three light-emitting devices 22 vary greatly, and there may be problems with poor display effects such as color distortion.

[0060] Based on this, in the SBS technology, the sizes of the three light emitting devices 22 can be set to adapt to the differences in luminous efficiency and lifespan. Figure 2 In the display panel 20 shown, a plurality of light emitting devices 22 are arranged in stripes. In this stripe arrangement, the size of the light emitting device can be easily adjusted by adjusting the width of the light emitting device 22. However, the stripe arrangement is easily affected by the mask setting and the pixel gap (PDL gap), and the aperture ratio is small. Figure 1 The in-plane arrangement with a relatively large aperture ratio shown in the figure is difficult to achieve the effect of different sizes of the light emitting devices 22 .

[0061] The present application embodiment provides a display panel, please refer to Figure 3 , Figure 3 1 is a schematic diagram of a display panel provided in an embodiment of the present application, wherein the display panel includes: a driving backplane 11 and a plurality of light emitting devices 12. Here, the driving backplane 11 can be used to carry other structures in the display panel 10, and the driving backplane 11 can also include a substrate, and a driving circuit ( Figure 3 (not shown), so that the driving backplane 11 can be used to drive the light-emitting device 12 to emit light.

[0062] The display panel provided by the embodiment of the present application may be a silicon-based organic light-emitting diode (OLED) display panel. The silicon-based OLED display panel may use a silicon wafer as a substrate, so that some circuit structures (such as a driving integrated circuit and a pixel circuit, etc.) can be integrated on the silicon wafer, thereby improving the integration degree of the display panel. In addition, compared with a conventional OLED display panel, the silicon-based OLED display panel may have a closer pixel arrangement, and thus may have a higher resolution and fineness. The advantages of the silicon-based OLED display panel, such as high resolution, high brightness and low power consumption, are beneficial to the application of the silicon-based OLED display panel in display fields such as VR and AR.

[0063] A plurality of light-emitting devices 12 are arranged in multiple columns in an array along a first direction X on a driving backplane 11, and are arranged in multiple rows in an array along a second direction Y. The first direction X intersects the second direction Y. Exemplarily, the first direction X may be perpendicular to the second direction Y. The plurality of light-emitting devices 12 include a plurality of first light-emitting devices 12a, a plurality of second light-emitting devices 12b, and a plurality of third light-emitting devices 12c, and the colors of the light emitted by the first light-emitting devices 12a, the second light-emitting devices 12b, and the third light-emitting devices 12c are different. Exemplarily, the colors of the light emitted by the plurality of light-emitting devices 12 may include red, green, or blue.

[0064] Among them, for two adjacent rows of light-emitting devices 12 arranged adjacent to each other, one row of light-emitting devices 12 includes: a plurality of first light-emitting devices 12a and a plurality of third light-emitting devices 12c arranged alternately, and the other row of light-emitting devices 12 are all second light-emitting devices 12b. For two adjacent columns of light-emitting devices 12 arranged adjacent to each other, one column of light-emitting devices 12 includes: a plurality of first light-emitting devices 12a and a plurality of second light-emitting devices 12b arranged alternately, and the other column of light-emitting devices 12 are all third light-emitting devices 12c. And the areas of the positive projections of at least two of the first light-emitting devices 12a, the second light-emitting devices 12b, and the third light-emitting devices 12c on the driving backplane 11 are different.

[0065] In this way, in a pixel region Q1, the second light-emitting device 12b is located on one side of the first light-emitting device 12a in the second direction Y, such as the upper side, and the third light-emitting device 12c is located on one side of the first light-emitting device 12a in the first direction X, such as the right side. Then, the three light-emitting devices 12 in a pixel unit are approximately arranged in the shape of the Chinese character 'ke'. On the one hand, compared with Figure 1 the triangular arrangement shown, on the basis of ensuring the same pixel gap, this 'ke'-shaped arrangement can more easily adjust the sizes of the light-emitting devices 12 of different colors. On the other hand, compared with Figure 2The stripe arrangement shown in the figure can increase the compactness of the arrangement of the light-emitting devices 12, thereby improving the aperture ratio.

[0066] The first light emitting device 12a, the second light emitting device 12b and the third light emitting device 12c in the pixel area Q1 can form a pixel unit. The distance between the centers of any two adjacent pixel units in the first direction X is equal, and the distance between the centers of any two adjacent pixel units in the second direction Y is equal, thus forming Figure 3 The arrangement structure shown can ensure that the density of the pixel units of the display panel 10 in the first direction X and the second direction Y is the same, thereby avoiding the problem of image distortion on the display panel.

[0067] It should be noted that Figure 3 The boundary shown by the dashed line may be the boundary of the light-emitting layer in the light-emitting device 12, and the pattern-filled area is the effective light-emitting area of ​​the light-emitting device 12. The aperture ratio is the ratio of the area of ​​the effective light-emitting area to the area of ​​the entire pixel unit.

[0068] In summary, the embodiment of the present application provides a display panel, which can adapt to the differences in luminous efficiency and life of light-emitting devices of different colors by setting the areas of the orthographic projections of at least two of the first light-emitting device, the second light-emitting device, and the third light-emitting device on the driving backplane to be different, thereby improving the uniformity of luminous emission. In addition, by setting the first light-emitting device and the third light-emitting device to be staggered in the first direction, and the first light-emitting device and the second light-emitting device to be staggered in the second direction, it is convenient to improve the compactness of the arrangement of the light-emitting devices on the basis of realizing the different areas of the light-emitting devices, thereby improving the aperture ratio, and further improving the display effect.

[0069] Optionally, in the present application, the ratio range of the area R of the orthographic projection of the light emitting device 12 for emitting red light on the driving backplane 11, the area G of the orthographic projection of the light emitting device 12 for emitting green light on the driving backplane 11, and the area B of the orthographic projection of the light emitting device 12 for emitting blue light on the driving backplane 11 is: 1:(1~2):(1.4~3.5).

[0070] In one implementation, the area of ​​the light emitting device and the light emitting efficiency of the light emitting device may be set to have opposite trends to improve light uniformity. Since the light emitting efficiency of the red light emitting device is greater than that of the blue light emitting device, and the light emitting efficiency of the red light emitting device is less than that of the green light emitting device, the embodiment of the present application may set B>R>G.

[0071] In another implementation, since the human eye is more sensitive to green light and has a greater demand, the embodiment of the present application may also set B>G>R. For example, R:G:B=1:1.2:2. However, the present application is not limited to these two implementations, and the ratio of R, G and B can satisfy the above ratio range.

[0072] The size structure of the light emitting device is described below:

[0073] Optionally, refer to Figure 3 The maximum dimension L1 of the second light emitting device 12b in the first direction X is greater than the maximum dimension L2 of the first light emitting device 12a in the first direction X.

[0074] And / or, the maximum dimension L3 of the third light emitting device 12c in the second direction Y is greater than the maximum dimension L4 of the first light emitting device 12a in the second direction Y. This includes the following three situations:

[0075] 1) Only the maximum dimension L1 of the second light emitting device 12b in the first direction X is larger than the maximum dimension L2 of the first light emitting device 12a in the first direction X. In this case, it is convenient to adjust the area of ​​the second light emitting device 12b on the driving backplane 11 to be larger than the area of ​​the first light emitting device 12a on the driving backplane 11.

[0076] 2) Only the maximum dimension L3 of the third light emitting device 12c in the second direction Y is larger than the maximum dimension L4 of the first light emitting device 12a in the second direction Y. In this case, it is convenient to adjust the area of ​​the third light emitting device 12c on the driving backplane 11 to be larger than the area of ​​the first light emitting device 12a on the driving backplane 11.

[0077] 3) The maximum dimension L1 of the second light emitting device 12b in the first direction X is greater than the maximum dimension L2 of the first light emitting device 12a in the first direction X, and the maximum dimension L3 of the third light emitting device 12c in the second direction Y is greater than the maximum dimension L4 of the first light emitting device 12a in the second direction Y. In this case, it is convenient to adjust the area of ​​the second light emitting device 12b on the driving backplane 11 to be greater than the area of ​​the first light emitting device 12a on the driving backplane 11, and the area of ​​the third light emitting device 12c on the driving backplane 11 to be greater than the area of ​​the first light emitting device 12a on the driving backplane 11.

[0078] In this way, in all three cases, it can be achieved that the areas of the direct projections of at least two of the first light-emitting device 12a, the second light-emitting device 12b and the third light-emitting device 12c on the driving backplane 11 are different, thereby adapting to the differences in luminous efficiency and lifespan of light-emitting devices of different colors, and further improving the uniformity of luminous emission.

[0079] Optionally, refer to Figure 3 and Figure 4 , Figure 4 1 is a schematic diagram of the structure of another display panel provided by an embodiment of the present application. The width of one of the second light emitting device 12b and the third light emitting device 12c is greater than the width of the other. The width L5 of the second light emitting device 12b is the maximum dimension of the second light emitting device 12b in the second direction Y, and the width L6 of the third light emitting device 12c is the maximum dimension of the third light emitting device 12c in the first direction X. This includes the following two cases:

[0080] 1) Please refer to Figure 3 The width L5 of the second light emitting device 12b is smaller than the width L6 of the third light emitting device 12c, so that the area of ​​the orthographic projection of the second light emitting device 12b on the driving backplane 11 is smaller than the area of ​​the third light emitting device 12c on the driving backplane 11.

[0081] 2) Please refer to Figure 4 , the width L5 of the second light emitting device 12b is greater than the width L6 of the third light emitting device 12c. In this way, the area of ​​the orthographic projection of the second light emitting device 12b on the driving backplane 11 can be greater than the area of ​​the third light emitting device 12c on the driving backplane 11.

[0082] Optionally, refer to Figure 3 and Figure 4 , the length of one of the second light emitting device 12b and the third light emitting device 12c is less than or equal to the length of the other. The length of the second light emitting device 12b is the maximum dimension L1 of the second light emitting device 12b in the first direction X, and the length of the third light emitting device 12c is the maximum dimension L3 of the third light emitting device 12c in the second direction Y. This includes the following two cases:

[0083] 1) Please refer to Figure 3 The length L2 of the second light emitting device 12b is less than or equal to the length L3 of the third light emitting device 12c, so that the area of ​​the positive projection of the second light emitting device 12b on the driving backplane 11 can be smaller than the area of ​​the third light emitting device 12c on the driving backplane 11.

[0084] 2) Please refer to Figure 4 , the width L5 of the second light emitting device 12b is greater than or equal to the width L6 of the third light emitting device 12c. In this way, the area of ​​the orthographic projection of the second light emitting device 12b on the driving backplane 11 can be greater than the area of ​​the third light emitting device 12c on the driving backplane 11.

[0085] Based on the above definition of the size structure of the light-emitting device, the relative sizes of the three light-emitting devices can be obtained, wherein the area of ​​the first light-emitting device 12a on the driving backplane 11 is S1, the area of ​​the orthographic projection of the second light-emitting device 12b on the driving backplane 11 is S2, and the area of ​​the third light-emitting device 12c on the driving backplane 11 is S3. Figure 3 In the case shown, S1<S2<S3, for Figure 4 In the case shown, S1<S3<S2.

[0086] Optionally, in the second light emitting device 12b and the third light emitting device 12c, the light emitting device 12 with a larger width is used to emit blue light, and the light emitting device 12 with a smaller width is used to emit one of red light and green light. And the first light emitting device 12a is used to emit the other of red light and green light. In this way, the light emitting device 12 with the largest area can be used to emit blue light, thereby improving the light emitting efficiency and life of the blue light emitting device, and further improving the display effect of the display panel.

[0087] for Figure 3 In the illustrated case, the first light emitting device 12a is used to emit one of red light and green light, the second light emitting device 12b is used to emit the other of the red light and green light, and the third light emitting device 12c is used to emit blue light.

[0088] for Figure 4 In the illustrated case, the first light emitting device 12a emits one of red light and green light, the second light emitting device 12b is used to emit blue light, and the third light emitting device 12c is used to emit the other of red light and green light.

[0089] The shape and structure of the light emitting device are described below:

[0090] Optionally, refer to Figure 3 The orthographic projection of the first light emitting device 12a on the driving backplane 11 is a block-shaped portion 12a1.

[0091] The orthographic projection of the second light-emitting device 12b on the driving backplane 11 includes: a first strip-shaped main body portion 12b1, and a first protruding portion 12b2 connected to at least one end of the first strip-shaped main body portion 12b1, and the overall extension direction of the first strip-shaped main body portion 12b1 is parallel to the first direction X. That is, the orthographic projection of the second light-emitting device 12b on the driving backplane 11 may include only one first protruding portion 12b2, or the orthographic projection of the second light-emitting device 12b on the driving backplane 11 may include two first protruding portions 12b2. The first protruding portion 12b2 can adjust the size of the second light-emitting device 12b, and can further increase the area of ​​the effective light-emitting region of the second light-emitting device 12b on the basis of the first strip-shaped main body portion 12b1, thereby increasing the aperture ratio.

[0098] Optionally, the shape of the first protrusion 12b2 includes: a triangle or a trapezoid. The shape of the second protrusion 12c2 includes: a triangle or a trapezoid. Figure 3 In the case shown, the shape of the first protrusion 12b2 is a triangle, and the shape of the second protrusion 12c2 is a trapezoid.

Figure 5 and Figure 6 In the illustrated case, the shape of the first protrusion 12b2 is a triangle, and the shape of the second protrusion 12c2 is also a triangle.

[0099] In the embodiment of the present application, the structure of the boundary of the first light emitting device includes various situations. Figure 3 The block portion 12a1 has two first boundaries A1 arranged opposite to each other in the first direction X, and two second boundaries A2 arranged opposite to each other in the second direction Y.

[0100] Among the two first boundaries A1, one first boundary A1 is: one of: a first bending boundary convex outward, a second bending boundary concave inward, and a first straight line boundary parallel to the second direction Y, and the other first boundary A1 is: one of: a first bending boundary convex outward, a second bending boundary concave inward, and a first straight line boundary parallel to the second direction Y.

[0101] Based on this, the two first boundaries A1 of the block portion 12a1 include six situations:

[0102] 1) Both first boundaries A1 are first bending boundaries.

[0103] 2) Both first boundaries A1 are second bending boundaries.

[0104] 3) Both first boundaries A1 are first straight line boundaries.

[0105] 4) One first boundary A1 is a first bending boundary, and another first boundary A1 is a second bending boundary.

[0106] 5) One first boundary A1 is a first bending boundary, and the other first boundary A1 is a first straight boundary.

[0107] 6) One first boundary A1 is a second bending boundary, and another first boundary A1 is a first straight boundary.

[0108] By setting whether the two first boundaries A1 are concave inward or convex outward, the area of ​​the positive projection of the first light-emitting device 12a on the driving backplane 11 can be adjusted, so as to adapt to various area requirements. For example, taking the first straight boundary as the standard, the first bending boundary can increase the area of ​​the first light-emitting device 12a, and the second bending boundary can reduce the area of ​​the second light-emitting device 12a.

[0109] Among the two second boundaries A2, one second boundary A2 is: one of: a third bending boundary convex outward, a fourth bending boundary concave inward, and a second straight line boundary parallel to the first direction X, and the other second boundary A2 is: one of: a third bending boundary convex outward, a fourth bending boundary concave inward, and a second straight line boundary parallel to the first direction X.

[0110] Based on this, the two second boundaries A2 of the block portion 12a1 include six situations:

[0111] 1) Both second boundaries A2 are third bending boundaries.

[0112] 2) Both second boundaries A2 are second bending boundaries.

[0113] 3) Both second boundaries A2 are second straight line boundaries.

[0114] 4) One second boundary A2 is a third bending boundary, and another second boundary A2 is a fourth bending boundary.

[0115] 5) One second boundary A2 is a third bending boundary, and another second boundary A2 is a second straight boundary.

[0116] 6) One second boundary A2 is a fourth bending boundary, and another second boundary A2 is a second straight boundary.

[0117] By setting whether the two second boundaries A2 are concave inward or convex outward, the area of ​​the positive projection of the first light-emitting device 12a on the driving backplane 11 can be adjusted, so as to adapt to various area requirements. For example, taking the second straight boundary as the standard, the third bending boundary can increase the area of ​​the first light-emitting device 12a, and the fourth bending boundary can reduce the area of ​​the second light-emitting device 12a.

[0118] It should be noted that, in the embodiment of the present application, the six situations of the two first boundaries A1 of the block portion 12a1 and the six situations of the two second boundaries A2 of the block portion 12a1 can be arbitrarily combined, so as to adjust the area of ​​the positive projection of the light-emitting device 12 on the driving backplane 11. Five exemplary embodiments are described below, but the present application is not limited thereto:

[0119] Please refer to Figure 3 and Figure 4 , the two first boundaries A1 of the block portion 12a1 are both first straight line boundaries, and the two second boundaries A2 of the block portion 12a1 are both second straight line boundaries.

[0120] Please refer to Figure 7 , Figure 7 1 is a schematic diagram of another display panel structure provided by an embodiment of the present application, wherein a first boundary A1 of the block portion 12a1 is a first bending boundary, and another first boundary A1 is a second bending boundary. A second boundary A2 of the block portion 12a1 is a third bending boundary, and another second boundary A2 is a second straight boundary.

[0121] Please refer to Figure 8 , Figure 8 It is a schematic diagram of another display panel provided by an embodiment of the present application, wherein a first boundary A1 of the block portion 12a1 is a first bending boundary, another first boundary A1 is a second bending boundary, and two second boundaries A2 of the block portion 12a1 are both fourth bending boundaries.

[0122] Please refer to Fig. 9 , Fig. 9 1 is a schematic diagram of another display panel structure provided by an embodiment of the present application, wherein the two first boundaries A1 of the block portion 12a1 are both second bending boundaries, and the two second boundaries A2 of the block portion 12a1 are both fourth bending boundaries.

[0123] Please refer to Fig.10 , Fig.10 It is a schematic diagram of the structure of another display panel provided by an embodiment of the present application, wherein a first boundary A1 of the block portion 12a1 is a first bending boundary, another first boundary A1 is a second bending boundary, and a second boundary A2 of the block portion 12a1 is a third bending boundary, and another second boundary A2 is a fourth bending boundary.

[0124] In the embodiment of the present application, the structure of the boundary between the second light emitting device and the third light emitting device also includes various situations. Specifically, it can be determined according to the shape structure of the boundary of the first light emitting device.

[0125] Optionally, the boundary of the second light emitting device can be found in Figure 3 , Figure 7 and Figure 8 The first strip-shaped main body portion 12b1 has two third boundaries A3 arranged opposite to each other in the second direction Y.

[0126] Among them, please refer to Figure 7In the case where the second boundary A2 in the block portion 12a1 close to the first strip-shaped main body portion 12b1 is the third bending boundary, the third boundary A3 closer to the third bending boundary among the two third boundaries A3 is recessed inwardly.

[0127] Please refer to Figure 8 In the case where the second boundary A2 in the block portion 12a1 close to the first strip-shaped main body portion 12b1 is the fourth bending boundary, the third boundary A3 of the two third boundaries A3 that is closer to the fourth bending boundary protrudes outward.

[0128] Please refer to Figure 3 In the case where the second boundary A2 in the block portion 12a1 close to the first strip-shaped main body portion 12b1 is a first straight boundary, the third boundary A3 of the two third boundaries A3 that is closer to the first straight boundary is parallel to the first direction X.

[0129] In this way, the shapes of the opposite sides of the block portion 12a1 and the first strip-shaped main body portion 12b1 can be complementary, so that the adjacent first light-emitting devices 12a and second light-emitting devices 12b can be arranged more closely, thereby improving the aperture ratio.

[0130] Optionally, for the boundary of the third light emitting device, please refer to Figure 3 , Figure 7 and Figure 8 The second strip-shaped main body portion 12c1 has two fourth boundaries A4 arranged opposite to each other in the first direction X.

[0131] Among them, please refer to Figure 7 In the case where the first boundary A1 in the block portion 12a1 close to the second strip-shaped main body portion 12c1 is the first bending boundary, the fourth boundary A4 of the two fourth boundaries A4 that is closer to the first bending boundary is recessed inward.

[0132] Please refer to Figure 8 In the case where the first boundary A1 in the block portion 12a1 close to the second strip-shaped main body portion 12c1 is the second bending boundary, the fourth boundary A4 of the two fourth boundaries A4 that is closer to the second bending boundary protrudes outward.

[0133] Please refer to Figure 3 In the case where the first boundary A1 in the block portion 12a1 close to the second strip-shaped main body portion 12c1 is a first straight line boundary, the fourth boundary A4 of the two fourth boundaries A4 that is closer to the first straight line boundary is parallel to the second direction Y.

[0134] In this way, the shapes of the opposite sides of the block portion 12a1 and the second strip-shaped main body portion 12c1 can be complementary, so that the adjacent first light-emitting devices 12a and third light-emitting devices 12c can be arranged more closely, thereby improving the aperture ratio.

[0135] Optionally, refer to Figure 3 The first protrusion 12b2 has at least one first oblique side A5, and the second protrusion 12c2 has at least one second oblique side A6.

[0136] There is a first oblique side A5 in the first protruding portion 12b2 and a second oblique side A6 in the second protruding portion 12c2 arranged opposite to each other. Exemplarily, the first oblique side A5 and the second oblique side A6 arranged opposite to each other can be parallel to each other, so that the adjacent second light emitting devices 12b and the third light emitting devices 12c can be arranged more closely, thereby improving the aperture ratio.

[0137] And for the relative arrangement of the first oblique side A5 and the second oblique side A6, one of the angle α1 between the first oblique side A5 and the first direction X and the angle α2 between the second oblique side A6 and the second direction Y is less than or equal to 45 degrees, and the other angle is greater than or equal to 45 degrees. Exemplarily, Figure 3 The angle α1 shown is smaller than the angle α2, which can make the area of ​​the positive projection of the third light emitting device 12c on the driving backplane 11 larger. Figure 4 In the illustrated case, the angle α1 may also be greater than the angle α2.

[0138] In an exemplary embodiment, please refer to Figure 3 and Fig.11 , Fig.11 yes Figure 3 A schematic diagram of a cross-sectional structure of a display panel provided ( Fig.11 yes Figure 3 A schematic diagram of the cross-sectional structure of the display panel at D1-D1 is provided, wherein the display panel 10 further includes: a first electrode layer E1, a pixel definition layer 13, a light-emitting layer E2, and a second electrode layer E3 stacked in a direction vertically and away from the driving backplane 11, wherein the first electrode layer E1, the light-emitting layer E2, and the second electrode layer E3 are used to form a plurality of light-emitting devices 12.

[0139] Among them, the first electrode layer E1 can be an anode, and the second electrode layer E3 can be a cathode. The driving circuit in the driving backplane 11 is electrically connected to the first electrode layer E1 and the second electrode layer E3. Under the control of the driving backplane 11, the first electrode layer E1 and the second electrode layer E3 cooperate to drive the light-emitting layer E2 to emit light.

[0140] The pixel definition layer 13 has a plurality of pixel openings K, and the plurality of light emitting devices 12 correspond to the plurality of pixel openings K respectively, and the orthographic projection of the light emitting device 12 on the driving backplane 11 overlaps with the orthographic projection of the corresponding pixel opening K on the driving backplane 11. The pixel definition layer 13 is used to divide the plurality of light emitting devices 12, and the area corresponding to the pixel opening K is the effective light emitting area of ​​the light emitting device 12, that is, Figure 3 An area filled with a pattern is shown.

[0141] Optionally, the light-emitting layer E2 includes: a first light-emitting block E21 belonging to the first light-emitting device 12a, a second light-emitting block E22 belonging to the second light-emitting device 12b, and a third light-emitting block E23 belonging to the third light-emitting device 12c. The areas corresponding to the three light-emitting blocks are Figure 3 The dashed area is shown.

[0142] In the first direction X, the adjacently distributed first light-emitting block E21 contacts the third light-emitting block E23. In the second direction Y, the adjacently distributed first light-emitting block E21 contacts the second light-emitting block E22. And the adjacently distributed second light-emitting block E22 contacts the third light-emitting block E23. In this way, the first light-emitting device 12a, the second light-emitting device 12b and the third light-emitting device 12c can be arranged more densely, thereby improving the aperture ratio.

[0143] In the display panel provided in the embodiment of the present application, the light-emitting layer E2 can be manufactured using a high-precision metal mask (Fine Metal Mask, FMM), which has high precision, and the light-emitting devices of various shapes and structures provided in the above embodiments can be realized.

[0144] Optionally, refer to Figure 3 and Fig.12 , Fig.12 yes Figure 3 Another cross-sectional structural diagram of a display panel provided ( Fig.11 yes Figure 3A schematic diagram of the cross-sectional structure of the display panel provided at D2-D2) shows that the pixel definition layer 13 has a plurality of gap areas Q2 on the side away from the driving backplane 11. The same gap area Q2 exists between two adjacent second light-emitting blocks E22 in the first direction X, and between two adjacent third light-emitting blocks E23 in the second direction Y. Here, the spacing between adjacent light-emitting devices 12 is the same to ensure the display effect. In order to ensure this, for the three light-emitting devices 12, the distance between the boundary of the effective light-emitting part of the light-emitting block in the pixel opening K and the outer edge of the light-emitting block can be the same. Exemplarily, for the adjacent second light-emitting block E22 and the third light-emitting block E23 in the pixel area Q1, there is an area where no light-emitting block is set at the position where the extension direction of the second light-emitting block E22 and the extension direction of the third light-emitting block E23 intersect, that is, the gap area Q2.

[0145] The display panel 10 further includes a plurality of support columns 14, which are respectively distributed in the plurality of gap regions Q1. The support columns 14 can be used to support the mask plate and serve as a partition structure between the light emitting devices 12. By arranging the support columns 14 in the gap region Q2, it is possible to avoid the support columns 14 affecting the arrangement of the light emitting devices 12, thereby avoiding affecting the aperture ratio of the display panel.

[0146] It should be noted that only Figure 3 The pixel arrangement shown is used as an example to illustrate the gap area Q2 and the support column 14. Figures 4 to 10 The pixel arrangement shown can be provided with a gap area Q2 and a support column 14, and the arrangement is similar to Figure 3 The embodiments shown are similar and will not be described in detail in this application.

[0147] This application combines the above-mentioned embodiment ( Figures 3 to 10 ) provides a display panel aperture ratio, and the related art ( Figure 2 ) are compared with the aperture ratios of display panels provided by FIG. 1 , and the aperture ratio data in Table 1 are measured under the same resolution and the same pixel gap. For example, the resolution can be 4000 pixels per inch (Pixels Per Inch, PPI), and the pixel gap can be 18 microns to 20 microns.

[0148] in, Figure 2 The stripe arrangement provided by the related art has an aperture ratio of only 2.59%. The aperture ratios of the pixel arrangement provided by the embodiments of the present application are greater than the aperture ratios of the stripe arrangement provided by the related art, which shows that the display panel provided by the embodiments of the present application can effectively improve the aperture ratio and thus improve the display effect when the area of ​​the light-emitting device is adjustable.

In addition, by setting the first light-emitting device and the third light-emitting device to be staggered in the first direction, and the first light-emitting device and the second light-emitting device to be staggered in the second direction, it is convenient to improve the compactness of the arrangement of the light-emitting devices on the basis of realizing the different areas of the light-emitting devices, thereby improving the aperture ratio, and further improving the display effect.
