[0038] It should be understood that although the terms first, second, third, etc., may be used to describe security areas, sub-pixels, etc. in the embodiments of this application, these security areas, sub-pixels, etc., should not be limited to these terms. These terms are only used to distinguish security areas, sub-pixels, etc. from each other. For example, without departing from the scope of the embodiments of this application, the first security area may also be referred to as the second security area, and similarly, the second security area may also be referred to as the first security area.

[0039] Through meticulous and in-depth research, the applicant in this case has provided a solution to the problems existing in the prior art.

[0040] Figure 1 This is a schematic diagram of a display panel provided in an embodiment of this application. Figure 2 This is a schematic diagram of the sub-pixel arrangement in a display panel provided in an embodiment of this application.

[0041] like Figure 1 and Figure 2 As shown, the display panel 01 includes multiple sub-pixels, and these sub-pixels include multiple first-color sub-pixels PX1, multiple second-color sub-pixels PX2, and multiple third-color sub-pixels PX3. The first-color sub-pixels PX1, second-color sub-pixels PX2, and third-color sub-pixels PX3 are sub-pixels of different colors. For example, among the first-color sub-pixels PX1, second-color sub-pixels PX2, and third-color sub-pixels PX3, one may be a red sub-pixel, one a green sub-pixel, and one a blue sub-pixel.

[0042] Please continue to refer to this. Figure 2 The display panel 01 also includes multiple security zones, including a first security zone S1, a second security zone S2, and a third security zone S3. Each of these security zones can be configured to correspond one-to-one with a first color sub-pixel PX1, a second color sub-pixel PX2, and a third color sub-pixel PX3, respectively. For example... Figure 2 The dashed borders surrounding each color sub-pixel indicate the safe zone corresponding to that color sub-pixel. The first safe zone S1 surrounds the first color sub-pixel PX1 and no sub-pixels are set within the first safe zone S1; the second safe zone S2 surrounds the second color sub-pixel PX2 and no sub-pixels are set within the second safe zone S2; the third safe zone S3 surrounds the third color sub-pixel PX3 and no sub-pixels are set within the third safe zone S3.

[0043] That is, the first color sub-pixel PX1 does not have the second color sub-pixel PX2 and the third color sub-pixel PX3 in a certain range of the periphery of the first color sub-pixel PX1, and the second color sub-pixel PX2 does not have the first color sub-pixel PX1 and the third color sub-pixel PX3 in a certain range of the periphery of the second color sub-pixel PX2, and the third color sub-pixel PX3 does not have the first color sub-pixel PX1 and the second color sub-pixel PX2 in a certain range of the periphery of the third color sub-pixel PX3, and the certain range of the periphery of the first color sub-pixel PX1 is the first safety area S1, the certain range of the periphery of the second color sub-pixel PX2 is the second safety area S2, and the certain range of the periphery of the third color sub-pixel PX3 is the third safety area S3.

[0044] In the embodiment of the present application, the areas of the first safety area S1, the second safety area S2 and the third safety area S3 are different from each other, for example, the area of the first safety area S1 is A1, the area of the second safety area S2 is A2, and the area of the third safety area S3 is A3, A1≠A2, A2≠A3, and A1≠A3. That is, the area of the first color sub-pixel PX1 without the second color sub-pixel PX2 and the third color sub-pixel PX3 in the periphery of the first color sub-pixel PX1 is A1, the area of the second color sub-pixel PX2 without the first color sub-pixel PX1 and the third color sub-pixel PX3 in the periphery of the second color sub-pixel PX2 is A2, and the area of the third color sub-pixel PX3 without the first color sub-pixel PX1 and the second color sub-pixel PX2 in the periphery of the third color sub-pixel PX3 is A3, A1≠A2, A2≠A3, and A1≠A3.

[0045] Figure 3 For the purpose of Figure 1 A schematic view of a cross section along the direction of M1-M2.

[0046] In the embodiment of the present application, each sub-pixel includes a light-emitting material layer, which is a material film layer for emitting light in the sub-pixel, and can be an organic light-emitting material layer. The display panel 01 provided in the embodiment of the present application can be an organic light-emitting display panel, and the light-emitting material layer included in each color sub-pixel can be an organic light-emitting material layer that can emit light of different colors.

[0047] In addition, each sub-pixel can further include an anode AE and a cathode CE, and the light-emitting material layer is located between the anode AE and the cathode CE. The anode AE and the cathode CE drive the light-emitting material layer located therebetween to emit light. In addition, each sub-pixel can further include an electron transport layer, a hole transport layer, an electron injection layer, a hole injection layer, etc. The cathodes CE in different sub-pixels can be electrically connected together, and the anodes AE in each sub-pixel can be electrically connected to the corresponding pixel circuit, respectively.

[0048] As Figure 3As shown, the first color sub-pixel PX1 includes a first color light-emitting material layer EL1, the second color sub-pixel PX2 includes a second color light-emitting material layer EL2, and the third color sub-pixel PX3 includes a third color light-emitting material layer EL3. The first color light-emitting material layer EL1, the second color light-emitting material layer EL2, and the third color light-emitting material layer EL3 are all located between the corresponding cathode CE and anode AE, and emit first color light, second color light, and third color light, respectively, under the driving of the cathode CE and the anode AE.

[0049] In addition, at least part of the light-emitting material layer is arranged in the opening of the pixel definition layer 10, and the opening of the pixel definition layer defines the light-emitting area of the sub-pixel, that is, the area of the sub-pixel can be defined by the area where the upper surface of the opening of the pixel definition layer 10 is located. As shown in the figure, Figure 3 As shown, the first color light-emitting material layer EL1 is arranged in the first opening 101 of the pixel definition layer 10, and the first opening 101 defines the area where the first color sub-pixel PX1 is located. The second color light-emitting material layer EL2 is arranged in the second opening 102 of the pixel definition layer 10, and the second opening 102 defines the area where the second color sub-pixel PX2 is located. The third color light-emitting material layer EL3 is arranged in the third opening 103 of the pixel definition layer 10, and the third opening 103 defines the area where the third color sub-pixel PX3 is located. Correspondingly, the distance between sub-pixels of different colors can be understood as the distance between the openings in the corresponding pixel definition layer 10.

[0050] The preparation of the light-emitting material layer can adopt an evaporation process, and a mask plate is needed in the evaporation process. Hereinafter, the preparation of the first color light-emitting material layer EL1 is taken as an example for description.

[0051] Figure 4 A schematic diagram for the preparation of the first color light-emitting material layer is shown in the figure, Figure 5 A partial plan view of the display panel and the mask plate is shown in the figure.

[0052] Please refer to Figure 4 and Figure 5 When the first color light-emitting material layer EL1 is prepared, the corresponding mask plate 30 is arranged on the pixel definition layer 10, and the hollow part 301 on the mask plate 30 used for preparing the first color light-emitting material layer EL1 exposes the first opening 101. Then the first color light-emitting material EL10 can reach the first opening 101 through the hollow part 301 on the corresponding mask plate 30 and continuously deposit to form the first color light-emitting material layer EL1.

[0053] However, in the process of evaporation, the mask plate 30 and the evaporation substrate exist a tolerance of alignment, which will cause the deviation between the hollow part 301 of the mask plate 30 and the opening of the pixel definition layer 10. Considering the alignment accuracy, the area of the hollow part 301 of the mask plate 30 is set to be larger than the area of the first opening 101, so as to ensure that when the mask plate 30 exists alignment deviation, the hollow part 301 can also expose the first opening 101, so that the first opening 101 can be completely filled with the first color light emitting material layer EL1, thereby avoiding the display color deficiency phenomenon.

[0054] In addition, in order to avoid the friction of the mask plate 30 to the prepared light emitting material layer, the mask plate 30 needs to be supported by the supporting column 20, that is, there is a gap between the mask plate 30 and the pixel definition layer 10.

[0055] In addition, in the process of making the mask plate 30, the position of the hollow part 301 will form an etching angle, that is, along the thickness direction of the mask plate 30, the width of the hollow part 301 is not a constant value.

[0056] The above reasons will cause the formation of the first color shadow layer EL1' in the process of evaporating the first color light emitting material layer EL1, and the thickness of the first color shadow layer EL1' will deviate from the thickness of the actual film layer to be evaporated (the first color light emitting material layer EL10). With the hollow part 301 of the mask plate 30 as the boundary, there will be a first color inner shadow layer EL11' on the inside corresponding to the hollow part 301 of the mask plate 30, and a first color outer shadow layer EL12' on the outside corresponding to the hollow part 301 of the mask plate 30. Among them, if the first color inner shadow layer EL11' is evaporated into the first opening 101 of the pixel, it will cause the thickness of the light emitting material layer in the part of the first opening 101 to deviate, causing the macroscopic mura; if the first color outer shadow layer EL12' is evaporated into the opening area of the adjacent pixel, it will cause color mixing.

[0057] Figure 6 A planar schematic diagram of a light emitting material layer in a display panel provided by an embodiment of the present application.

[0058] Based on the above preparation process, it can be seen that when a light emitting material layer of a certain color is prepared, a shadow layer of the same color light emitting material will be formed around it. Therefore, as shown in Figure 6 a first color shadow layer EL1' is formed around the first color light emitting material layer EL1, a second color shadow layer EL2' is formed around the second color light emitting material layer EL2, and a third color shadow layer EL3' is formed around the third color light emitting material layer EL3.

[0059] In order to avoid the shadow layer of the light emitting material of the arbitrary sub-pixel periphery causing cross color to the adjacent sub-pixels, the shadow layer of the light emitting material should not exceed the area defined by the outer contour of the safety zone corresponding to the arbitrary sub-pixel. That is, as shown in FIG. 6, the first color shadow layer EL1' is located in the area defined by the outer contour of the first safety zone S1, the second color shadow layer EL2' is located in the area defined by the outer contour of the second safety zone S2, and the third color shadow layer EL3' is located in the area defined by the outer contour of the third safety zone S3. Figure 6

[0060] The reason for setting a certain area of the safety zone in the periphery of the sub-pixel is to reduce the influence of the shadow layer of the light emitting material on the adjacent sub-pixels of different colors. Therefore, the safety zone corresponding to the sub-pixel can be determined by extending the outer contour of the sub-pixel outward and stopping the extension when the outer edge of the position where the shadow layer of the light emitting material can appear is reached. The area passed through by the outer contour of the sub-pixel during the extension is the safety zone of the sub-pixel.

[0061] As analyzed above, the outer edge of the position where the shadow layer of the light emitting material can appear is related to the size of the hollow part 301 of the mask plate 30, the gap between the mask plate 30 and the pixel definition layer 10, and the etching angle of the hollow part in the mask plate 30. In addition, the outer edge of the position where the shadow layer of the light emitting material can appear is also related to the alignment accuracy of the mask plate 30. Among them, the size of the hollow part of the mask plate 30, the gap between the mask plate 30 and the pixel definition layer 10, and the etching angle of the hollow part in the mask plate 30 mainly affect the area of the shadow layer of the light emitting material, which can be understood as mainly affecting the width of the shadow layer of the light emitting material in one direction. The alignment accuracy of the mask plate 30 mainly affects the width of the offset of the shadow layer of the light emitting material relative to the edge of the sub-pixel in one direction.

[0062] Therefore, when the safety zone of the sub-pixel is determined according to the prepared sub-pixel, for example, when the safety zone of the sub-pixel is determined in the product verification stage of the display panel, the distance between the edge of the safety zone and the sub-pixel is the sum of the shadow width A and the offset width B. After determining the distance between the edge of the safety zone at different positions and the sub-pixel, the area of the safety zone can be determined. The shadow width A is half of the difference between the distance between the two edges of the shadow layer and the distance between the two edges of the sub-pixel. The offset width B is the empirical value of the alignment accuracy of the mask plate 30, which can also be the experimental value of the alignment accuracy of the mask plate 30. For example, the empirical value of the alignment accuracy of the mask plate 30 is usually about 3 μm, and the offset width B can be about 3 μm. Generally, with the further development of technology, the machine accuracy can be further improved. The offset width B here can be further 2.5 μm, 2 μm, etc.

[0063] Figure 7 ​This is a schematic diagram illustrating a method for dividing the periphery security zone of a sub-pixel in a display panel, as provided in an embodiment of this application.

[0064] by Figure 7 The division of the first security area S1 is illustrated using the first color sub-pixel PX1, which is enclosed by the first security area S1 shown in the diagram, as an example. Figure 7 As shown, the distance X11 between two opposite edges along the first direction X in the first color shadow layer EL1' is determined, and the distance X12 between two opposite edges along the first direction X in the first color sub-pixel PX1 is determined. Then, the shadow width A used to determine the first safe area S1 in the first direction X is determined. X = (X11-X12) / 2; Determine the distance Y11 between two opposite edges along the second direction Y in the first color shadow layer EL1', and determine the distance Y12 between two opposite edges along the second direction Y in the first color sub-pixel PX1, then the shadow width A used to determine the first safe area S1 in the second direction Y is... Y = (Y11-Y12) / 2. Therefore, the distance between the outer edge of the first safe zone S1 and the first color sub-pixel PX1 in the first direction X is (shadow width A). X +Offset width B X ), which is [(X11-X12) / 2+B X The distance between the outer edge of the second safe zone S2 and the first color sub-pixel PX1 in the second direction Y is (shadow width A). Y +Offset width B Y ), which is [(Y11-Y12) / 2+B Y ]. Among them, B X B is an empirical value for the alignment accuracy of the mask 30 in the first direction X, or an experimental value for the alignment accuracy of the mask 30 in the first direction X. Y B represents either an empirical value for the alignment accuracy of the mask 30 in the second direction Y, or an experimental value for the alignment accuracy of the mask 30 in the second direction Y. X Can be with B Y They are equal. Following the method described above, the outer edge of the first safety zone S1 can be determined, and thus the first safety zone S1 can be determined. B X It can be 3μm, 2.5μm, and 2μm; B Y It can be 3μm, 2.5μm and 2μm.

[0065] The division of the second security zone S2 and the third security zone S3 is similar to that of the first security zone S1, and will not be repeated here.

[0066] It should be noted that, depending on the required thickness and / or area of ​​different luminescent material layers, the area of ​​the cutout portion of the mask used for preparing luminescent material layers of different colors using the vapor deposition process can vary, and / or the vapor deposition time and the gas density of the vapor deposition material can also differ. Therefore, the width of the luminescent material shadow layer surrounding different color sub-pixels is basically different; that is, the shadow width A used to determine the edge of the safe zone corresponding to different color sub-pixels is not entirely the same. In the embodiments of this application, an important parameter for controlling the different areas of the first safe zone S1, the second safe zone S2, and the third safe zone S3 is that the widths of the first safe zone S1, the second safe zone S2, and the third safe zone S3 are different in the same direction.

[0067] It should be noted that the safe areas corresponding to adjacent sub-pixels may partially overlap. The safe area at the overlapping location is considered a part of the safe area corresponding to each adjacent sub-pixel. For example, ... Figure 2 As shown, the first security areas S1 and the third security areas S3 corresponding to the first color sub-pixel PX1 and the third color sub-pixel PX3 respectively, which are adjacently arranged in the first direction X, may overlap in the first direction X; the second security areas S2 and the third security areas S3 corresponding to the second color sub-pixel PX2 and the third color sub-pixel PX3 respectively, which are adjacently arranged in the first direction X, overlap in the first direction X.

[0068] In the technical solution provided in this application embodiment, the risk of color crosstalk caused by the shadow layer to adjacent sub-pixels can be assessed based on the area of ​​the shadow layer generated during the fabrication of the luminescent material layer in the sub-pixel, and the area of ​​the safe zone surrounding the sub-pixel can be set according to the color crosstalk risk. In this application embodiment, the area of ​​the safe zone surrounding different color sub-pixels is different. On the one hand, color crosstalk between different color sub-pixels can be avoided, ensuring the display effect of the display panel 01; on the other hand, each safe zone can achieve its respective function without occupying too much area, ensuring the resolution of the display panel 01.

[0069] In one embodiment of this application, such as Figure 2 As shown, the light-emitting area of ​​the third color sub-pixel PX3 is greater than the light-emitting area of ​​the first color sub-pixel PX1 and greater than the light-emitting area of ​​the second color sub-pixel PX2, and the area of ​​the third security area S3 is greater than the area of ​​the first security area S1.

[0070] Furthermore, the area of ​​the third security area S3 is larger than the area of ​​the second security area S2. That is, among the first color sub-pixel PX1, the second color sub-pixel PX2, and the third color sub-pixel PX3, and their respective first security areas S1, second security areas S2, and third security areas S3, the area of ​​the third color sub-pixel PX3 is the largest, and the area of ​​the third security area S3 surrounding it is also the largest.

[0071] As analyzed above, the area of the hollow part on the mask plate for depositing the light-emitting material is larger than the opening on the pixel definition layer where the light-emitting material is located, because the risk of color loss caused by the incomplete filling of the light-emitting material in the opening due to the misalignment of the mask plate is reduced. Moreover, the positions on the opening of the pixel definition layer where the light-emitting material is not filled are mainly located at the edges of the opening. When the area of a sub-pixel is larger, the edges of the opening where the light-emitting material is located are longer, and the risk of color loss is higher. Therefore, when the light-emitting material of a sub-pixel with a larger area is deposited, the area of the hollow part on the mask plate used is also larger relative to the area of the sub-pixel.

[0072] The more the area of the hollow part on the mask plate used for preparing the light-emitting material layer of the sub-pixel is increased relative to the area of the sub-pixel, the larger the area of the light-emitting material shadow layer on the periphery of the sub-pixel is, that is, the higher the risk of crosstalk with adjacent sub-pixels is. In the embodiment, the area of the third safety area S3 corresponding to the third color sub-pixel PX3 with the largest area among the first color sub-pixel PX1, the second color sub-pixel PX2 and the third color sub-pixel PX3 is designed to be the largest, so that the risk of crosstalk between the third color sub-pixel PX3 and other color sub-pixels adjacent thereto can be reduced.

[0073] In a technical solution corresponding to the embodiment, the third color sub-pixel PX3 is a blue sub-pixel. In an organic light-emitting display panel, that is, a display panel including organic light-emitting devices in each sub-pixel, the light-emitting efficiency of the organic light-emitting device included in the blue sub-pixel is relatively low, which is usually lower than the light-emitting efficiency of the organic light-emitting device included in the red sub-pixel and lower than the light-emitting efficiency of the organic light-emitting device included in the green sub-pixel. Therefore, the light-emitting area of the third color sub-pixel PX3 is designed to be larger, that is, the light-emitting area of the third color sub-pixel PX3 is designed to be larger than the light-emitting area of the first color sub-pixel PX1 and larger than the light-emitting area of the second color sub-pixel PX2, so as to compensate for the problem of low light-emitting efficiency.

[0074] In an embodiment of the present application, as shown in Figure 1 and Figure 2 , along the first direction X, the first color sub-pixel PX1, the second color sub-pixel PX2 and the third color sub-pixel PX3 are arranged alternately in sequence. Figure 1 and Figure 2 , the sub-pixels arranged along the first direction X constitute a pixel row, and any one pixel row is periodically arranged with a pixel group as the smallest repeating unit, and the pixel group includes one first color sub-pixel PX1, one second color sub-pixel PX2 and one third color sub-pixel PX3.

[0075] For example, Figure 2The illustrated first odd-numbered pixel row includes a pixel group G1 and the first odd-numbered pixel row is periodically arranged with the pixel group G1 as a minimum repeating unit, and the pixel group G1 includes the second color sub-pixel PX2, the third color sub-pixel PX3 and the first color sub-pixel PX1 which are sequentially and adjacently arranged along the first direction X; Figure 1 and Figure 2 The illustrated second even-numbered pixel row includes a pixel group G2 and the second even-numbered pixel row is periodically arranged with the pixel group G2 as a minimum repeating unit, and the pixel group G2 includes the first color sub-pixel PX1, the second color sub-pixel PX2 and the third color sub-pixel PX3 which are sequentially and adjacently arranged along the first direction X.

[0076] In the embodiment, the light emitting area of the third color sub-pixel PX3 is greater than the light emitting area of the first color sub-pixel PX1 and greater than the light emitting area of the second color sub-pixel PX2; and along the first direction X, the distance between the first color sub-pixel PX1 and the adjacent third color sub-pixel PX3 is greater than the distance between the first color sub-pixel PX1 and the adjacent second color sub-pixel PX2, and the distance between the second color sub-pixel PX2 and the adjacent third color sub-pixel PX3 is greater than the distance between the second color sub-pixel PX2 and the adjacent first color sub-pixel PX1.

[0077] As shown in Figure 2 , in one pixel row, the distance between the first color sub-pixel PX1 and the adjacent third color sub-pixel PX3 on the left side thereof is d13 and the distance between the first color sub-pixel PX1 and the adjacent second color sub-pixel PX2 on the right side thereof is d12, d13>d12. That is, the first color sub-pixel PX1 located between the second color sub-pixel PX2 and the third color sub-pixel PX3 is arranged closer to the second color sub-pixel PX2 and farther away from the third color sub-pixel PX3, so that the color mixing of the third color sub-pixel PX3 and the first color sub-pixel PX1 adjacent thereto along the first direction X can be more effectively avoided.

[0078] Further, as shown in Figure 2 , in one pixel row, the distance between the second color sub-pixel PX2 and the adjacent third color sub-pixel PX3 on the right side thereof is d23 and the distance between the second color sub-pixel PX2 and the adjacent first color sub-pixel PX1 on the left side thereof is d12, d23>d12. That is, the second color sub-pixel PX2 located between the first color sub-pixel PX1 and the third color sub-pixel PX3 is arranged closer to the first color sub-pixel PX1 and farther away from the third color sub-pixel PX3, so that the color mixing of the third color sub-pixel PX3 and the second color sub-pixel PX2 adjacent thereto along the first direction X can be more effectively avoided.

[0079] In the embodiment, by setting d13>d12 and d23>d12, the third color sub-pixel PX3 is far away from the first color sub-pixel PX1 and the second color sub-pixel PX2 respectively located on the left and right sides of the third color sub-pixel PX3, thereby avoiding color mixing between the third color sub-pixel PX3 and other color sub-pixels adjacent to the third color sub-pixel PX3 along the first direction X. In the embodiment, the area of the third safety area S3 is greater than the area of the first safety area S1 and greater than the area of the second safety area S2 by setting d13>d12 and d23>d12.

[0080] Figure 8 A sub-pixel arrangement schematic diagram in a display panel provided by an embodiment of the present application, Figure 9 A cross-sectional schematic diagram along the N1-N2 direction in the embodiment. Figure 8

[0081] In an embodiment of the present application, as shown in the accompanying drawings, Figure 8 And Figure 9 The first color sub-pixel PX1 includes a first color light-emitting material layer EL1, the second color sub-pixel PX2 includes a second color light-emitting material layer EL2, and the third color sub-pixel PX3 includes a third color light-emitting material layer EL3. The first color light-emitting material layer EL1, the second color light-emitting material layer EL2, and the third color light-emitting material layer EL3 are all located between the corresponding cathode CE and anode AE, and emit first color light, second color light, and third color light respectively under the driving of the cathode CE and the anode AE.

[0082] In the embodiment of the present application, as shown in the accompanying drawings, Figure 9 The thickness d2 of the second color light-emitting material layer EL2 is greater than the thickness d1 of the first color light-emitting material layer EL1 and greater than the thickness d3 of the third color light-emitting material layer EL3. That is, among the first color light-emitting material layer EL1, the second color light-emitting material layer EL2, and the third color light-emitting material layer EL3 included in the first color sub-pixel PX1, the second color sub-pixel PX2, and the third color sub-pixel PX3 respectively, the thickness d2 of the second color light-emitting material layer EL2 included in the second color sub-pixel PX2 is the thickest.

[0083] When the evaporation process is used to prepare the light-emitting material layers of various colors, the evaporation time required for preparing the second color light-emitting material layer EL2 is longer, and / or the gas density of the second color light-emitting material is higher, which will cause the width of the second color shadow layer EL2’ to increase additionally. For example, as shown in the accompanying drawings, Figure 8 The width of the second color shadow layer EL2’ is greater than the width of the first color shadow layer EL1’.

[0084] In the embodiment of the present application, as shown in the accompanying drawings, Figure 8 ​As shown, the area of the second safety zone S2 is larger than the area of the first safety zone S1. The greater the width of the shadow layer of a sub-pixel, the greater the risk of crosstalk with its adjacent sub-pixels. In the present embodiment, the area of the second safety zone S2 corresponding to the second color sub-pixel PX2 with a greater width of the shadow layer in the periphery is designed to be larger than the first color sub-pixel PX1, which can reduce the risk of crosstalk of other color sub-pixels adjacent to the second color sub-pixel PX2.

[0085] Further, in combination with Figure 8 and Figure 9 , the width of the second color shadow layer EL2' is greater than the width of the third color shadow layer EL3', and the area of the second safety zone S2 is greater than the area of the third safety zone S3.

[0086] In a technical solution corresponding to the present embodiment, the second color sub-pixel PX2 is a red sub-pixel. In an organic light-emitting display panel, i.e., a display panel including organic light-emitting devices in each sub-pixel, the thickness of the red light-emitting material layer included in the red sub-pixel is greater than the thickness of the blue light-emitting material layer included in the blue sub-pixel and greater than the thickness of the green light-emitting material layer included in the green sub-pixel.

[0087] In a conventional design, the area of the red sub-pixel is usually smaller than the area of the green sub-pixel and smaller than the area of the blue sub-pixel, but when considering the setting of the safety zone in the periphery of the sub-pixel, the design of the smaller area of the red sub-pixel does not increase the resolution of the display panel, and even reduces the resolution of the display panel. This is mainly because if the area of the red sub-pixel is set too small, the thickness of the red light-emitting material layer included therein may need to be set larger, and the increase in the thickness of the red light-emitting material layer has a greater impact on the area of the safety zone in the periphery than the decrease in the area of the red sub-pixel, i.e., the increase in the area of the safety zone in the periphery of the red sub-pixel caused by the increase in the thickness of the red light-emitting material layer is greater than the decrease in the area of the safety zone in the periphery of the red sub-pixel caused by the decrease in the area of the red sub-pixel. Therefore, in the technical solution provided in the present embodiment, the area of the red sub-pixel can be set relatively large without significantly reducing the resolution of the display panel, for example, the area of the red sub-pixel can be substantially the same as the area of the green sub-pixel. More specifically, the area difference between the red sub-pixel and the green sub-pixel is within 10%.

[0088] In addition, when the area of the red sub-pixel and the area of the green sub-pixel are close, the area of the red sub-pixel, the area of the green sub-pixel and the area of the blue sub-pixel are close. Then, in the safety zones of the periphery of the red sub-pixel, the safety zones of the periphery of the green sub-pixel and the safety zones of the periphery of the blue sub-pixel, the overlapping area between adjacent safety zones can be larger, so there is an opportunity to increase the area of each color sub-pixel without increasing the risk of color mixing of different color sub-pixels. For example: the area difference between the red sub-pixel and the green sub-pixel is within 10%. The area difference between the blue sub-pixel and the red sub-pixel is within 30%.

[0089] In an embodiment of the present application, as shown in Figure 8 , along the first direction X, the first color sub-pixel PX1, the second color sub-pixel PX2 and the third color sub-pixel PX3 are arranged alternately in sequence. Among them, Figure 8 , the arrangement of different color sub-pixels is the same as that shown in Figure 2 , which will not be repeated here.

[0090] In the present embodiment, as shown in Figure 9 , the width of the second color shadow layer EL2' in the periphery of the second color sub-pixel PX2 is greater than the width of the first color shadow layer EL1' in the periphery of the first color sub-pixel PX1, and greater than the width of the third color shadow layer EL3' in the periphery of the third color sub-pixel PX3; and along the first direction X, the distance between the third color sub-pixel PX3 and the adjacent second color sub-pixel PX2 is greater than the distance between the third color sub-pixel PX3 and the adjacent first color sub-pixel PX1.

[0091] As shown in Figure 8 , along the first direction, the distance between the third color sub-pixel PX3 and the adjacent second color sub-pixel PX2 on the left side is d23 and the distance between the third color sub-pixel PX3 and the adjacent first color sub-pixel PX1 on the right side is d13, d23>d13. That is, the third color sub-pixel PX3 located between the first color sub-pixel PX1 and the second color sub-pixel PX2 is arranged closer to the first color sub-pixel PX1 and farther away from the second color sub-pixel PX2, which can more effectively avoid the color mixing between the second color shadow layer EL2' in the periphery of the second color sub-pixel PX2 and the third color sub-pixel PX3 adjacent to it along the first direction X.

[0092] In this embodiment, by setting d23 > d13, the distance between the second color sub-pixel PX2 and the third color sub-pixel PX1 is made larger, thereby avoiding color mixing between the second color shadow layer EL2' surrounding the second color sub-pixel PX2 and the adjacent third color sub-pixel PX3 along the first direction X. Furthermore, in this embodiment, setting d23 > d13 can make the area of ​​the second safe area S2 larger than the area of ​​the first safe area S1.

[0093] Furthermore, such as Figure 8 As shown, when the area of ​​the second security area S2 is larger than the area of ​​the third security area S3, along the first direction X, the distance between the first color sub-pixel PX1 and the adjacent second color sub-pixel PX2 is d12, and the distance between the first color sub-pixel PX1 and the adjacent third color sub-pixel PX2 is d13, where d12 > d13. That is, the first color sub-pixel PX1 located between the third color sub-pixel PX3 and the second color sub-pixel PX2 is positioned closer to the third color sub-pixel PX3 and further away from the second color sub-pixel PX2, which can more effectively prevent color mixing between the second color shadow layer EL2' surrounding the second color sub-pixel PX2 and the first color sub-pixel PX1 adjacent to it along the first direction X.

[0094] In this embodiment, by setting d23 > d13 and d12 > d13, the distance between the second color sub-pixel PX2 and the first color sub-pixels PX1 and the third color sub-pixels PX3 located to its left and right respectively is relatively large, thereby avoiding color mixing between the second color sub-pixel PX2 and other color sub-pixels adjacent along the first direction X. Furthermore, in this embodiment, by setting d23 > d13 and d12 > d13, the area of ​​the second safe area S2 can be made larger than the area of ​​the first safe area S1 and larger than the area of ​​the third safe area S3.

[0095] Figure 10 This is a schematic diagram of the sub-pixel arrangement in a display panel provided in an embodiment of this application.

[0096] In one embodiment of this application, when the light-emitting area of ​​the third color sub-pixel PX3 is greater than the light-emitting area of ​​the first color sub-pixel PX1 and greater than the light-emitting area of ​​the second color sub-pixel PX2, and the thickness d2 of the second color light-emitting material layer EL2 is greater than the thickness d1 of the first color light-emitting material layer EL1 and greater than the thickness d3 of the third color light-emitting material layer EL3, such as Figure 10 As shown, the area of ​​the third security zone S3 is larger than the area of ​​the second security zone S2, and the area of ​​the second security zone S2 is larger than the area of ​​the first security zone S1.

[0097] The third color sub-pixel PX3 can be a blue sub-pixel, the second color sub-pixel PX2 can be a red sub-pixel, and the first color sub-pixel PX1 can be a green sub-pixel, and the first color sub-pixel PX1, the second color sub-pixel PX2 and the third color sub-pixel PX3 are arranged alternately along the first direction X.

[0098] In a technical solution corresponding to the embodiment, as shown in Figure 10 The distance between the first color sub-pixel PX1 and the adjacent third color sub-pixel PX3 is greater than the distance between the first color sub-pixel PX1 and the adjacent second color sub-pixel PX2 along the first direction X, the distance between the second color sub-pixel PX2 and the adjacent third color sub-pixel PX3 is greater than the distance between the second color sub-pixel PX2 and the adjacent first color sub-pixel PX1, and the distance between the third color sub-pixel PX3 and the adjacent second color sub-pixel PX2 is greater than the distance between the third color sub-pixel PX3 and the adjacent first color sub-pixel PX1, that is, d13>d12, d23>d12, and d23>d13.

[0099] That is, among the first color sub-pixel PX1, the second color sub-pixel PX2 and the third color sub-pixel PX3 arranged alternately along the first direction X, the distance d23 between the adjacent third color sub-pixel PX3 and the second color sub-pixel PX2 is the largest, the distance d12 between the adjacent second color sub-pixel PX3 and the first color sub-pixel PX1 is the smallest, and the distance d13 between the adjacent third color sub-pixel PX3 and the first color sub-pixel PX1 is in the middle.

[0100] The distance between the third color sub-pixel PX3 and the second color sub-pixel PX2 is set to be the largest, so that the area of the third color shadow layer EL3' and the area of the second color shadow layer EL2' caused by the large area of the mask plate used for preparing the light-emitting material included in the third color sub-pixel PX3 and the large thickness of the light-emitting material included in the second color sub-pixel PX2 can be taken into account, and the risk of color crosstalk between the second color sub-pixel PX2 and the third color sub-pixel PX3 is reduced.

[0101] In addition, d13>d12, d23>d12, and d23>d13, so that the area of the second safety area S2 and the area of the third safety area S3 are both greater than the area of the first safety area S1. Since the area of the second safety area S2 and the area of the third safety area S3 are both large, the area of the overlap between the two is also increased, which is beneficial to optimizing the arrangement of the sub-pixels to improve the resolution.

[0102] Figure 11 A sub-pixel arrangement diagram in a display panel is provided in the embodiment.

[0103] In an embodiment of the present application, as shown in Figure 11 The plurality of first color sub-pixels PX1, the plurality of second color sub-pixels PX2 and the plurality of third color sub-pixels PX3 included in the display panel 01 are periodically arranged in a first minimum period C1, and the first minimum period C1 includes a first pixel PXa and a second pixel PXb arranged adjacent to each other along a first direction X.

[0104] The first pixel PXa and the second pixel PXb each include a first color sub-pixel PX1, a second color sub-pixel PX2 and a third color sub-pixel PX3. In the first pixel PXa, the second color sub-pixel PX2 and the third color sub-pixel PX3 are arranged adjacent to each other along the first direction X, and the first color sub-pixel PX1 overlaps the second color sub-pixel PX2 in a second direction Y and overlaps the third color sub-pixel PX3 in the second direction Y. In the second pixel PXb, the second color sub-pixel PX2 and the third color sub-pixel PX3 are arranged adjacent to each other along the first direction X, and the first color sub-pixel PX1 overlaps the second color sub-pixel PX2 in the second direction Y and overlaps the third color sub-pixel PX3 in the second direction Y. The second direction Y is transverse to the first direction X, and preferably, the second direction Y can be perpendicular to the first direction X. That is, in the first pixel PXa and the second pixel PXb, the first color sub-pixel PX1, the second color sub-pixel PX2 and the third color sub-pixel PX3 are arranged in a "pin" shape.

[0105] Further, in the first pixel PXa and the second pixel PXb arranged adjacent to each other along the first direction X, the first color sub-pixel PX1 in the first pixel PXa is arranged adjacent to the second color sub-pixel PX2 or the third color sub-pixel PX3 in the second pixel PXb, and the first color sub-pixel PX1 in the second pixel PXb is arranged adjacent to the second color sub-pixel PX2 or the third color sub-pixel PX3 in the first pixel PXa. As shown in Figure 11 In the same first minimum period C1, the first color sub-pixel PX1 in the first pixel PXa is arranged along the first direction X with the second color sub-pixel PX2 and the third color sub-pixel PX3 in the second pixel PXb, and the first color sub-pixel PX1 in the second pixel PXb is arranged along the first direction X with the second color sub-pixel PX2 and the third color sub-pixel PX3 in the first pixel PXa.

[0106] In addition, in the embodiment of the present application, as shown in Figure 11 The first pixel PXa can be arranged adjacent to each other along the second direction Y and the second pixel PXb can be arranged adjacent to each other along the second direction Y. Specifically, as shown in Figure 11As shown, the first color sub-pixels PX1 are arranged in sequence along the second direction Y, the second color sub-pixels PX2 are arranged in sequence along the second direction Y, and the third color sub-pixels PX3 are arranged in sequence along the second direction Y, and the first color sub-pixels PX1, the second color sub-pixels PX2 and the third color sub-pixels PX3 are alternately arranged along the first direction.

[0107] In a technical solution corresponding to the embodiment, as shown in Figure 11 In any one of the first pixel PXa and the second pixel PXb, the midpoint O1 between the second color sub-pixel PX2 and the third color sub-pixel PX3 overlaps the first color sub-pixel PX1 along the second direction Y, that is, the median line of the line connecting the midpoint of the second color sub-pixel PX2 and the midpoint of the third color sub-pixel PX3 passes through the first color sub-pixel PX1. Then, the color mixing effect of different color sub-pixels in the same pixel can be better.

[0108] In any one of the first pixel PXa and the second pixel PXb, the midpoint O1 between the second color sub-pixel PX2 and the third color sub-pixel PX3 can be arranged in a staggered manner along the second direction Y, that is, the median line of the line connecting the midpoint of the second color sub-pixel PX2 and the midpoint of the third color sub-pixel PX3 passes through the first color sub-pixel PX1 and does not pass through the midpoint O2 of the first color sub-pixel PX1.

[0109] In an implementation manner, the first color sub-pixel PX1 is a green sub-pixel. Since the human eye is more sensitive to green, by arranging the green sub-pixel to overlap the midpoint between the other two sub-pixels in the same pixel, the white balance of the pixel can be easily realized.

[0110] In some technical solutions, as shown in Figure 11 The midpoints of the first color sub-pixels PX1 arranged along the first direction X are aligned, that is, the midpoints of the plurality of first color sub-pixels PX1 arranged along the first direction X are on the same straight line.

[0111] In some technical solutions, as shown in Figure 11 The midpoints of the second color sub-pixels PX2 arranged along the first direction X are aligned, that is, the midpoints of the plurality of second color sub-pixels PX2 arranged along the first direction X are on the same straight line.

[0112] In some technical solutions, as shown in Figure 11 The midpoints of the third color sub-pixels PX3 arranged along the first direction X are aligned, that is, the midpoints of the plurality of third color sub-pixels PX3 arranged along the first direction X are on the same straight line.

[0113] In a technical solution corresponding to the embodiment, as shown in Figure 12As shown, the midpoints of the first color sub-pixels PX1 arranged along the first direction X are aligned, the midpoints of the second color sub-pixels PX2 arranged along the first direction X are aligned, and the midpoints of the third color sub-pixels PX3 arranged along the first direction X are aligned.

[0114] Figure 12 This is a schematic diagram of the sub-pixel arrangement in a display panel provided in an embodiment of this application.

[0115] In some technical solutions, such as Figure 12 As shown, the midpoints of the first color sub-pixels PX1 arranged along the first direction X are misaligned in the first direction X, that is, the midpoints of the multiple first color sub-pixels PX1 arranged along the first direction X are on a broken line.

[0116] Among them, such as Figure 12 As shown, although the midpoint of the first color sub-pixel PX1 arranged along the first direction X is misaligned in the first direction X, the first color sub-pixels PX1 arranged along the first direction X can overlap in the first direction X.

[0117] In some technical solutions, such as Figure 12 As shown, the midpoints of the second color sub-pixels PX2 arranged along the first direction X are misaligned in the first direction X, that is, the midpoints of the multiple second color sub-pixels PX2 arranged along the first direction X are on a broken line.

[0118] Among them, such as Figure 12 As shown, although the midpoints of the second color sub-pixels PX2 arranged along the first direction X are misaligned in the first direction X, the second color sub-pixels PX2 arranged along the first direction X can overlap in the first direction X.

[0119] In some technical solutions, such as Figure 12 As shown, the midpoints of the third color sub-pixels PX3 arranged along the first direction X are misaligned in the first direction X, that is, the midpoints of multiple third color sub-pixels PX3 arranged along the first direction X are on a broken line.

[0120] Among them, such as Figure 12 As shown, although the midpoint of the third color sub-pixel PX3 arranged along the first direction X is misaligned in the first direction X, the third color sub-pixel PX3 arranged along the first direction X can overlap in the first direction X.

[0121] In some technical solutions corresponding to this embodiment, such as Figure 13 As shown, the midpoint of the first color sub-pixel PX1 arranged along the first direction X is misaligned in the first direction X, the midpoint of the second color sub-pixel PX2 arranged along the first direction X is misaligned in the first direction X, and the midpoint of the third color sub-pixel PX3 arranged along the first direction X is misaligned in the first direction X.

[0122] When the midpoints of the subpixels of the same color are misaligned in the first direction X, the midpoints of the subpixels of different colors are also misaligned in the first direction X. When the midpoints of the subpixels of different colors and adjacent to each other are misaligned in the first direction X, the distance between the two will increase, and there is a chance to set a larger safety area, thereby increasing the area of the subpixels.

[0123] Figure 13 A subpixel arrangement diagram in a display panel is provided in an embodiment of the present application.

[0124] In some technical solutions, in the first color subpixels PX1, the second color subpixels PX2 and the third color subpixels PX3, the midpoints of the subpixels of the same color arranged at least partially along the first direction X are misaligned in the first direction X, and the midpoints of the subpixels of the same color arranged at least partially along the first direction X are aligned in the first direction X.

[0125] For example, as shown in FIG. 1, each first color subpixel PX1 in each row of first color subpixels PX1 is arranged along the first direction Y, and the midpoints of adjacent first color subpixels PX1 are misaligned in the first direction X; each second color subpixel PX2 in each row of second color subpixels PX2 is arranged along the first direction X, and the midpoints of adjacent second color subpixels PX2 are misaligned in the first direction X; each third color subpixel PX3 in the first row, the third row and the fifth row of third color subpixels PX3 is arranged along the first direction X, and the midpoints of each third color subpixel PX3 are aligned in the first direction X. Figure 11 In some technical solutions, as shown in FIG. 2, the midpoints of the first color subpixels PX1 arranged along the second direction Y are aligned, that is, the midpoints of the first color subpixels PX1 arranged along the second direction Y are on the same straight line.

[0126] Figure 11 In some technical solutions, as shown in FIG. 3, the midpoints of the second color subpixels PX2 arranged along the second direction Y are aligned, that is, the midpoints of the second color subpixels PX2 arranged along the second direction Y are on the same straight line.

[0127] In some technical solutions, as shown in FIG. 4, the midpoints of the third color subpixels PX3 arranged along the second direction Y are aligned, that is, the midpoints of the third color subpixels PX3 arranged along the second direction Y are on the same straight line. Figure 11 In some technical solutions, as shown in FIG. 5, the midpoints of the third color subpixels PX3 arranged along the second direction Y are aligned, that is, the midpoints of the third color subpixels PX3 arranged along the second direction Y are on the same straight line.

[0128] Figure 11 In a technical solution corresponding to an embodiment of the present application, as shown in FIG. 6, the midpoints of the first color subpixels PX1 arranged along the second direction Y are aligned, that is, the midpoints of the first color subpixels PX1 arranged along the second direction Y are on the same straight line.

[0129] In a technical solution corresponding to an embodiment of the present application, as shown in FIG. 7, the midpoints of the second color subpixels PX2 arranged along the second direction Y are aligned, that is, the midpoints of the second color subpixels PX2 arranged along the second direction Y are on the same straight line. Figure 14 ​​As shown, the midpoints of the first color sub-pixels PX1, the second color sub-pixels PX2, and the third color sub-pixels PX3 arranged along the second direction Y are aligned.

[0130] Figure 14 This is a schematic diagram of the sub-pixel arrangement in a display panel provided in an embodiment of this application.

[0131] In some technical solutions, such as Figure 14 As shown, the midpoints of the first color sub-pixels PX1 arranged along the second direction Y are misaligned in the second direction Y, that is, the midpoints of multiple first color sub-pixels PX1 arranged along the second direction Y are on a broken line.

[0132] Among them, such as Figure 14 As shown, although the midpoint of the first color sub-pixel PX1 arranged along the second direction Y is misaligned in the second direction Y, the first color sub-pixel PX1 arranged along the second direction Y can overlap in the second direction Y.

[0133] In some technical solutions, such as Figure 14 As shown, the midpoints of the second color sub-pixels PX2 arranged along the second direction Y are misaligned in the second direction Y, that is, the midpoints of multiple second color sub-pixels PX2 arranged along the second direction Y are on a broken line.

[0134] Among them, such as Figure 14 As shown, although the midpoint of the second color sub-pixel PX2 arranged along the second direction Y is misaligned in the second direction Y, the second color sub-pixel PX2 arranged along the second direction Y can overlap in the second direction Y.

[0135] In some technical solutions, such as Figure 14 As shown, the midpoints of the third color sub-pixels PX3 arranged along the second direction Y are misaligned in the second direction Y, that is, the midpoints of multiple third color sub-pixels PX3 arranged along the second direction Y are on a broken line.

[0136] Among them, such as Figure 14 As shown, although the midpoint of the third color sub-pixel PX3 arranged along the second direction Y is misaligned in the second direction Y, the third color sub-pixel PX3 arranged along the second direction Y can overlap in the second direction Y.

[0137] In some technical solutions corresponding to this embodiment, such as Figure 14 As shown, the midpoint of the first color sub-pixel PX1 arranged along the second direction Y is misaligned in the second direction Y, the midpoint of the second color sub-pixel PX2 arranged along the second direction Y is misaligned in the second direction Y, and the midpoint of the third color sub-pixel PX3 arranged along the second direction Y is misaligned in the second direction Y.

[0138] As shown in Figure 15 , the row direction in the figure can be the first direction X and the column direction can be the second direction Y, the midpoints of adjacent same-color subpixels in the same column are staggered in the second direction Y, and the distance between the two subpixels in the same column and adjacent subpixels in the respective row is different. For example, the uppermost third-color subpixel PX3 and the middle third-color subpixel PX3 in the first column are staggered in the column direction, and the distance between the uppermost third-color subpixel PX3 and the second-color subpixel PX2 on the left side thereof can be different from the distance between the middle third-color subpixel PX3 and the second-color subpixel PX2 on the left side thereof, and the distance between the uppermost third-color subpixel PX3 and the first-color subpixel PX1 on the right side thereof can also be different from the distance between the middle third-color subpixel PX3 and the first-color subpixel PX1 on the right side thereof. That is, the area of the safety zone of different subpixels can be flexibly adjusted, for example, the overlapping area of the safety zones corresponding to adjacent subpixels can be increased.

[0139] Figure 15 A subpixel arrangement schematic diagram in a display panel is provided in the embodiments of the present application.

[0140] In some technical solutions, among the first-color subpixels PX1, the second-color subpixels PX2, and the third-color subpixels PX3, the midpoints of at least part of the same-color subpixels arranged along the second direction Y are staggered in the second direction Y, and the midpoints of at least part of the same-color subpixels arranged along the second direction Y are aligned in the second direction Y.

[0141] For example, as shown in Figure 15 , each first-color subpixel PX1 in the rightmost column of first-color subpixels PX1 is arranged along the second direction Y, and the midpoints of the first-color subpixels PX1 are aligned in the second direction Y; each second-color subpixel PX2 in the leftmost column of second-color subpixels PX2 is arranged along the second direction Y, and the midpoints of the second-color subpixels PX2 are aligned in the second direction Y; and each third-color subpixel PX3 in any column of third-color subpixels PX3 is arranged along the second direction Y, and the midpoints of the third-color subpixels PX3 are aligned in the second direction Y. Also, as shown in Figure 11 , each first-color subpixel PX1 in the left fifth column of subpixels is arranged along the second direction Y, and the midpoints of adjacent first-color subpixels PX1 are staggered in the second direction Y; each second-color subpixel PX2 in the left seventh column of subpixels is arranged along the second direction Y, and the midpoints of adjacent second-color subpixels PX2 are staggered in the second direction Y.

[0142] In a technical solution corresponding to the present embodiment, as shown in Figure 12- Figure 15As shown, among the first color sub-pixel PX1, the second color sub-pixel PX2 and the third color sub-pixel PX3 adjacently arranged along the third direction Z, the center points of the three are staggered in the third direction Z1, the third direction Z1 intersects with the first direction X and intersects with the second direction Y.

[0143] For example, the first color sub-pixel PX1, the second color sub-pixel PX2 and the third color sub-pixel PX3 can all be square or rounded square, and the extension directions of two diagonal lines in the square are respectively parallel to the first direction X and the second direction Y, then the angle between the third direction Z1 and the first direction X can be 45° and the angle between the third direction Z1 and the second direction Y can also be 45°.

[0144] An implementation manner corresponding to the technical solution is that, although the center points of the first color sub-pixel PX1, the second color sub-pixel PX2 and the third color sub-pixel PX3 adjacently arranged along the third direction Z are staggered in the third direction Z1, the first color sub-pixel PX1 and the second color sub-pixel PX2 adjacently arranged along the third direction Z1 exist overlap, and the third color sub-pixel PX3 and the second color sub-pixel PX2 adjacently arranged along the third direction Z1 exist overlap.

[0145] Among them, the first color sub-pixel PX1 is a green sub-pixel, the second color sub-pixel PX2 is a red sub-pixel, and the third color sub-pixel PX3 is a blue sub-pixel, the width of the first color sub-pixel PX1 along the fourth direction Z2 is W1, the width of the third color sub-pixel PX3 along the fourth direction Z2 is W2, and the fourth direction Z2 is perpendicular to the third direction Z1. Along the third direction Z1, the overlapping part of the first color sub-pixel PX1 and the second color sub-pixel PX2 adjacently arranged along the fourth direction has a width of W3; along the third direction Z1, the overlapping part of the third color sub-pixel PX3 and the second color sub-pixel PX2 adjacently arranged along the fourth direction Z2 has a width of W4; wherein 0.5≤(W3 / W1)≤1, 0.5≤(W4 / W2)≤1.

[0146] In some technical solutions, as shown in the figure, Figure 12 As shown, the midpoints of the two first color sub-pixels PX1 adjacently arranged along the second direction Y and the midpoints of the second color sub-pixels PX2 adjacently arranged along the first direction X are the vertices of a virtual parallelogram P1. That is, the connecting line of the midpoints of the two first color sub-pixels PX1 adjacently arranged along the second direction Y and the midpoints of the second color sub-pixels PX2 adjacently arranged along the first direction X can form a virtual parallelogram P1.

[0147] The midpoint of the two first color sub-pixels PX1 arranged adjacent along the second direction Y can be slightly offset along the second direction Y, or the midpoint of the first color sub-pixel PX1 and the second color sub-pixel PX2 arranged adjacent along the first direction X can be slightly offset along the first direction X. As shown in Figure 14 and Figure 12- Figure 15 indicated, the virtual parallelogram P1 can be a parallelogram not containing a right angle.

[0148] In some technical solutions, as shown in Figure 12 , the midpoint of the two second color sub-pixels PX2 arranged adjacent along the second direction Y and the midpoint of the third color sub-pixel PX3 adjacent to the second color sub-pixel along the first direction X are the vertices of the virtual parallelogram P2. That is, the line connecting the midpoint of the two second color sub-pixels PX2 arranged adjacent along the second direction Y and the midpoint of the third color sub-pixel PX3 adjacent to the second color sub-pixel along the first direction X can form the virtual parallelogram P2.

[0149] The midpoint of the two second color sub-pixels PX2 arranged adjacent along the second direction Y can be slightly offset along the second direction Y, or the midpoint of the second color sub-pixel PX2 and the third color sub-pixel PX3 arranged adjacent along the first direction X can be slightly offset along the first direction X. As shown in Figure 14 and Figure 12- Figure 15 indicated, the virtual parallelogram P2 can be a parallelogram not containing a right angle.

[0150] In some technical solutions, as shown in Figure 12 , the midpoint of the two third color sub-pixels PX3 arranged adjacent along the second direction Y and the midpoint of the first color sub-pixel PX1 adjacent to the third color sub-pixel along the first direction X are the vertices of the virtual parallelogram P3. That is, the line connecting the midpoint of the two third color sub-pixels PX3 arranged adjacent along the second direction Y and the midpoint of the first color sub-pixel PX1 adjacent to the third color sub-pixel along the first direction X can form the virtual parallelogram P3.

[0151] The midpoint of the two third color sub-pixels PX3 arranged adjacent along the second direction Y can be slightly offset along the second direction Y, or the midpoint of the third color sub-pixel PX3 and the first color sub-pixel PX1 arranged adjacent along the first direction X can be slightly offset along the first direction X. As shown in Figure 14 and Figure 12 indicated, the virtual parallelogram P3 can be a parallelogram not containing a right angle.

[0152] In a technical solution corresponding to the embodiment, as shown in Figure 14 and Figure 13As shown in FIG. 1, the virtual parallelogram P1, the virtual parallelogram P2 and the virtual parallelogram P3 are all parallelograms without right angles. Then, the centers of the sub-pixels of the same color arranged along the second direction Y are misaligned in the second direction Y, and / or the centers of the sub-pixels of the same color arranged along the first direction X are misaligned in the first direction X, which can improve the color edge phenomenon at the edge of the display panel.

[0153] In a technical solution corresponding to the embodiment, as shown in Figure 15 and Figure 15 , of the virtual parallelogram P1, the virtual parallelogram P2 and the virtual parallelogram P3, part of the virtual parallelograms are parallelograms without right angles and part of the virtual parallelograms are parallelograms with right angles. For example, as shown in Figure 11 , the virtual parallelogram P1 is a parallelogram without right angles, and the virtual parallelogram P2 and the virtual parallelogram P3 are parallelograms with right angles.

[0154] In some technical solutions, as shown in Figure 11 , the midpoints of two first color sub-pixels PX1 arranged adjacent along the second direction Y and the midpoints of two second color sub-pixels PX2 arranged adjacent along the first direction X adjacent to the two first color sub-pixels PX1 are the vertices of a virtual rectangle R1. That is, the line connecting the midpoints of the two first color sub-pixels PX1 arranged adjacent along the second direction Y and the midpoints of the two second color sub-pixels PX2 arranged adjacent along the first direction X adjacent to the two first color sub-pixels PX1 can form the virtual rectangle R1.

[0155] In some technical solutions, as shown in Figure 11 , the midpoints of two second color sub-pixels PX2 arranged adjacent along the second direction Y and the midpoints of two third color sub-pixels PX3 arranged adjacent along the first direction X adjacent to the two second color sub-pixels PX2 are the vertices of a virtual rectangle R2. That is, the line connecting the midpoints of the two second color sub-pixels PX2 arranged adjacent along the second direction Y and the midpoints of the two third color sub-pixels PX3 arranged adjacent along the first direction X adjacent to the two second color sub-pixels PX2 can form the virtual rectangle R2.

[0156] In some technical solutions, as shown in Figure 11 , the midpoints of two third color sub-pixels PX3 arranged adjacent along the second direction Y and the midpoints of two first color sub-pixels PX1 arranged adjacent along the first direction X adjacent to the two third color sub-pixels PX3 are the vertices of a virtual rectangle R3. That is, the line connecting the midpoints of the two third color sub-pixels PX3 arranged adjacent along the second direction Y and the midpoints of the two first color sub-pixels PX1 arranged adjacent along the first direction X adjacent to the two third color sub-pixels PX3 can form the virtual rectangle R3.

[0157] In a technical solution corresponding to the embodiment, as shown inFigure 13 As shown in FIG. 1, the virtual parallelogram P1, the virtual parallelogram P2 and the virtual parallelogram P3 are all virtual rectangles, i.e., the virtual parallelogram P1 is specifically a virtual rectangle R1, the virtual parallelogram P2 is specifically a virtual rectangle R2, and the virtual parallelogram P3 is specifically a virtual rectangle R3.

[0158] In a technical solution corresponding to the embodiment, as shown in FIG. 2, the virtual parallelogram P1, the virtual parallelogram P2 and the virtual parallelogram P3 are all parallelograms not containing right angles. Figure 15 Figure 15 As shown in FIG. 3, among the virtual parallelogram P1, the virtual parallelogram P2 and the virtual parallelogram P3, some are parallelograms not containing right angles and some are virtual rectangles. For example, as shown in FIG. 4, the virtual parallelogram P1 is a parallelogram not containing right angles, the virtual parallelogram P2 is specifically a virtual rectangle R2, and the virtual parallelogram P3 is specifically a virtual rectangle R3. Figure 16

[0159] Figure 16 FIG. 5 is a partial schematic view of a display panel provided by an embodiment of the present application.

[0160] In an embodiment of the present application, when the first color sub-pixel PX1, the second color sub-pixel PX2 and the third color sub-pixel PX3 are arranged in sequence along the first direction X, as shown in FIG. 6, the width of the first safety area S1 along the second direction Y is greater than the width of the first safety area S1 along the first direction X, the width of the second safety area S2 along the second direction Y is greater than the width of the second safety area S2 along the first direction X, and the width of the third safety area S3 along the second direction Y is greater than the width of the third safety area S3 along the first direction X. That is, when the first color sub-pixel PX1, the second color sub-pixel PX2 and the third color sub-pixel PX3 are arranged in sequence along the first direction X, the width of the safety area of each sub-pixel along the second direction Y is greater than the width of the safety area of each sub-pixel along the first direction X. Figure 17

[0161] FIG. 7 is a preparation schematic view of a display panel provided by an embodiment of the present application. Figure 17 As shown in FIG. 8, in order to increase the evaporation efficiency of the light-emitting material on the display panel 01, the crucible used in the evaporation process is usually a linear crucible 40. The outlet side of the linear crucible 40 can include multiple nozzles, and the periphery of the outlet side of the linear crucible 40 is provided with an angle plate 42. The angle plate 42 can control the angle of the evaporation material when it exits from the outlet of the linear crucible 40, so as to avoid the evaporation material near the side wall of the linear crucible 40 from exiting at too large an angle.

[0162] Figure 17

[0163] ​​​​However, if the angle plates 42 on both sides of the linear crucible 40 are far apart along its length, the angle of the vapor-deposited material at positions far from these angle plates 42 is not controlled by them and will exit at a larger angle along the length of the linear crucible 40. Conversely, if the angle plates 42 on both sides of the linear crucible 40 are close together along its width, the phenomenon of the vapor-deposited material exiting at a larger angle along the width of the linear crucible 40 is less pronounced.

[0164] like Figure 16 As shown, when using a linear crucible 40 to prepare a luminescent material layer, the length direction of the linear crucible 40 can be parallel to the second direction Y and the direction of movement can be parallel to the first direction X.

[0165] If the length direction of the linear crucible 40 is parallel to the second direction Y, then a large amount of luminescent material will be emitted at a large angle in the first direction X. However, if the movement direction of the linear crucible 40 is parallel to the first direction X, then due to the presence of the angle plate 42, the amount of luminescent material emitted at a large angle in the first direction X is very small.

[0166] In this embodiment of the application, by setting the width of each security area along the second direction Y to be larger, cross-coloring between different color sub-pixels can be effectively avoided.

[0167] In the display panel provided in this application, along the first direction X, first color sub-pixels PX1, second color sub-pixels PX2, and third color sub-pixels PX3 are arranged alternately; along the second direction Y, first color sub-pixels PX1 are arranged adjacent to each other, second color sub-pixels PX2 are arranged adjacent to each other, and third color sub-pixels PX3 are arranged adjacent to each other. For example, as... Figure 17 and Figure 11 As shown, in the same sub-pixel row, the first color sub-pixel PX1, the second color sub-pixel PX2, and the third color sub-pixel PX3 are arranged alternately; in the same sub-pixel column, the first color sub-pixel PX1 is arranged next to each other in sequence, or the second color sub-pixel PX2 is arranged next to each other in sequence, or the third color sub-pixel PX3 is arranged next to each other in sequence.

[0168] Furthermore, in the display panel provided in this application, a pixel includes a first color sub-pixel PX1, a second color sub-pixel PX2, and a third color sub-pixel PX3 arranged adjacent to each other. For example, as... Figure 17 In the corresponding embodiments, both the first pixel PXa and the second pixel PXb include a first color sub-pixel PX1, a second color sub-pixel PX2, and a third color sub-pixel PX3 arranged in a triangular pattern. Each pixel includes a driving circuit that drives the three sub-pixels, and the unit composed of these three driving circuits has equal lengths in the X and Y directions.

[0169] In the pixel arrangement manner of the display panel provided by the embodiment of the present application, if the length direction of the linear crucible 40 is parallel to the first direction X when the light-emitting material is evaporated, the risk of color mixing of different color sub-pixels is greater because the distance between different color sub-pixels arranged along the first direction X is smaller than the distance between sub-pixels arranged along the second direction Y. When the light-emitting material is evaporated, the length direction of the linear crucible 40 is parallel to the second direction Y, which can effectively reduce the probability of occurrence of the above risk.

[0170] It should be noted that, Figure 17 Only the preparation of the first color light-emitting material layer EL1 by using the linear crucible and the mask plate 30 is shown, and the second color light-emitting material layer EL2 and the third color light-emitting material layer EL3 are prepared in the same manner.

[0171] In combination with Figure 16 With Figure 18 When the linear crucible 40 is used to prepare the light-emitting material layer, because there are more light-emitting materials that exit at a large angle in the second direction Y and a small amount of light-emitting materials that exit at a large angle in the first direction X, the width of the shadow layer of the light-emitting material in the second direction Y is larger and the width of the shadow layer of the light-emitting material in the first direction X is smaller.

[0175] In combination with Figure 18 With Figure 19 , Figure 16The second color sub-pixel PX2 includes a second color light-emitting material layer EL2, and a second color shadow layer EL2' is included in the second safety area S2.

[0177] In combination Figure 18 With Figure 19 , Figure 16 The third color sub-pixel PX3 includes a third color light-emitting material layer EL3, and a third color shadow layer EL3' is included in the third safety area S3. The third color shadow layer EL3' surrounds the third color light-emitting material layer EL3 and is connected with the third color light-emitting material layer EL3 in the same layer.

[0178] The third color light-emitting material layer EL3 and the third color shadow layer EL3' are different structures obtained by using the same material in the same process. The third color light-emitting material layer EL3 is arranged in the opening of the pixel definition layer PDL and is used for light emission; the third color shadow layer EL3' is formed on the part of the periphery of the pixel definition layer PDL when the third color light-emitting material layer EL3 is prepared, and the third color shadow layer EL3' is arranged in the third safety area S3 and does not exceed the third safety area S3.

[0179] In combination Figure 18 With Figure 19 , Figure 2 The width of the first color shadow layer EL1' along the second direction Y is greater than the width of the first color shadow layer EL1' along the first direction X, the width of the second color shadow layer EL2' along the second direction Y is greater than the width of the second color shadow layer EL2' along the first direction X, and the width of the third color shadow layer EL3' along the second direction Y is greater than the width of the third color shadow layer EL3' along the first direction X.
