Description

Technical Field

[0001] The embodiments of the present invention relate to the field of display technology, and in particular to a display panel and a display device. Background Art

[0002] Organic Light-Emitting Diode (OLED) display panels are widely used in the field of display technology due to their many advantages such as active luminescence, high contrast, and no viewing angle limitation.

[0003] In OLED display panels, in order to enhance the migration and recombination efficiency of carriers, functional film layers such as electron transport layers, electron injection layers, hole transport layers, and hole injection layers are usually provided between the electrodes and the light-emitting layers of the OLED devices. However, since these functional film layers are usually arranged to cover the entire surface of all organic light-emitting devices in the display panel, when the display panel is displaying, in addition to the normal longitudinal migration of carriers corresponding to different OLED devices from their respective cathodes and / or anodes to the corresponding light-emitting layers, there may also be a situation where carriers migrate laterally between different OLED devices through the above-mentioned functional film layers, that is, lateral leakage occurs, resulting in the problem of crosstalk between different sub-pixels when the display panel is displaying. For example, sub-pixels that should not emit light may emit light, which is a phenomenon of stealing light, affecting the display effect. Utility Model Content

[0004] In view of this, embodiments of the present invention provide a display panel and a display device to solve the problem of light-emitting devices being strayed due to lateral leakage in the related art.

[0005] In a first aspect, an embodiment of the present invention provides a display panel, comprising:

[0006] substrate;

[0007] A plurality of sub-pixels arranged in an array along a first direction and a second direction on the same side of a substrate, the sub-pixels including a first sub-pixel, a second sub-pixel, and a third sub-pixel, wherein the i-th row of sub-pixels includes the first sub-pixel and the third sub-pixel arranged alternately along the first direction; the i+1-th row of sub-pixels includes the third sub-pixel and the second sub-pixel arranged alternately along the first direction; the j-th column of sub-pixels includes the first sub-pixel and the third sub-pixel arranged alternately along the second direction; and the j+1-th column of sub-pixels includes the third sub-pixel and the second sub-pixel arranged alternately along the second direction; the second direction intersects the first direction;

[0008] The partition portion includes at least a first partition portion and a second partition portion, wherein the first partition portion at least partially surrounds the first sub-pixel and includes a first notch; the second partition portion at least partially surrounds the second sub-pixel and includes a second notch;

[0009] a supporting portion, wherein the supporting portion is located between the first sub-pixel and the adjacent second sub-pixel along the third direction, and the supporting portion is located between two adjacent third sub-pixels along the fourth direction; the third direction intersects the first direction and the second direction respectively; the fourth direction intersects the first direction and the second direction respectively; and the third direction intersects the fourth direction;

[0010] The adjacent first sub-pixels and second sub-pixels include at least one of the non-notch portion of the first partition portion, the non-notch portion of the second partition portion and the supporting portion; and at least one of the first sub-pixel and the second sub-pixel includes a protruding portion and a main body portion, and the edge of the protruding portion away from the main body portion includes an arc segment, and the arc segment bulges toward the side away from the main body portion.

[0011] In a second aspect, an embodiment of the present invention provides a display device, comprising the above-mentioned display panel.

[0012] The display panel and display device provided by the embodiments of the present invention can isolate or extend the path of the lateral leakage current transmitted between the first sub-pixel and the sub-pixel adjacent to it through the common layer by providing a first isolation portion that partially surrounds the first sub-pixel and a second isolation portion that partially surrounds the second sub-pixel. In addition, the isolation or extension of the path of the lateral leakage current transmitted between the second sub-pixel and the sub-pixel adjacent to it through the common layer can suppress the transmission of the lateral leakage current, which is beneficial to improving the display effect, especially improving the display effect at low grayscale.

[0013] Moreover, the embodiment of the present invention can avoid the situation where the second electrode formed after the first partition portion and the second partition portion is disconnected or thinned at the notch by setting a first notch in the first partition portion and a second notch in the second partition portion. The second electrode can be formed into a continuous structure with a larger thickness at the notch, which is beneficial to reducing the voltage drop of the signal transmitted by the second electrode during the transmission process and improving the voltage uniformity of the second electrode in the display area.

[0014] In addition, the embodiment of the present invention sets a support portion in the display panel. On the one hand, the support portion can be used to support the mask used in the process. On the other hand, the setting of the support portion can also extend the path for the lateral leakage current to be transmitted between two adjacent sub-pixels through the common layer, which can suppress the transmission of the lateral leakage current and improve the reliability of the display panel.

[0015] In addition, when setting the above-mentioned first notch, second notch and supporting portion, the embodiment of the present invention makes the adjacent first sub-pixel and second sub-pixel include at least one of the non-notch portion of the first partition portion, the non-notch portion of the second partition portion and the supporting portion. By comprehensively considering the positions of the first notch, the second notch and the supporting portion, it is possible to avoid setting the first notch and the second notch simultaneously between the first sub-pixel and the second sub-pixel that are not adjacent to the supporting portion, and ensure that the first sub-pixel and the second sub-pixel that are not adjacent to the supporting portion include at least one suppression structure for extending or isolating the conduction path of the lateral leakage current, so as to suppress the transmission of the lateral leakage current between the first sub-pixel and the second sub-pixel, reduce the possibility of crosstalk between the first sub-pixel and the second sub-pixel, and reduce the possibility of the first sub-pixel and the second sub-pixel secretly lighting up, optimize the low grayscale display effect of the display panel, and improve the display quality of the display panel.

[0016] Secondly, the embodiment of the present invention makes at least one of the first sub-pixel and the second sub-pixel include a protruding portion and a main portion, and the edge of the protruding portion away from the main portion includes an arc segment, and the arc segment protrudes toward the side away from the main portion, wherein the protruding portion and the main portion can be located within the virtual circumscribed quadrilateral of the first sub-pixel or the second sub-pixel. On the one hand, compared with setting the shapes of the first sub-pixel and the second sub-pixel according to their respective virtual circumscribed quadrilaterals, the setting method provided by the embodiment of the present invention can reduce the area of ​​the first sub-pixel or the second sub-pixel, thereby increasing the distance between the first sub-pixel or the second sub-pixel and another adjacent sub-pixel, which is beneficial to reducing the process difficulty of setting the partition portion and the support portion between the first sub-pixel and another adjacent sub-pixel, and reducing the process difficulty of setting the partition portion and the support portion between the second sub-pixel and another adjacent sub-pixel.

[0017] On the other hand, while ensuring that the minimum spacing between two adjacent sub-pixels remains unchanged, compared with the case where the shape of the first sub-pixel or the second sub-pixel is set to be square, the embodiment of the present invention sets the first sub-pixel or the second sub-pixel to include a protrusion, which is equivalent to cutting the arc edge of the circumscribed virtual quadrilateral corresponding to the first sub-pixel or the second sub-pixel. At least one vertex of the first sub-pixel or the second sub-pixel can be retracted toward the center of the circumscribed virtual quadrilateral close to the second sub-pixel, thereby leaving space for another sub-pixel adjacent to the sub-pixel to expand outward, thereby increasing the area of ​​the expanded sub-pixel and improving its aperture ratio. Moreover, compared with the related art, the pixel design method provided by the embodiment of the present invention does not increase the process difficulty, such as on the basis of keeping the relevant process parameters (such as the minimum aperture spacing between adjacent sub-pixels, FMM r ib, etc.) consistent with the existing technology or still having design redundancy, and can increase the total aperture ratio of the pixel unit including a first sub-pixel, a second sub-pixel and two third sub-pixels, which is beneficial to improving the display effect and display quality of the display panel.

[0056] In order to better understand the technical solution of the present invention, the embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0057] It should be understood that the embodiments described are only a portion of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative work are within the scope of protection of the present invention.

[0058] The terms used in the embodiments of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The singular forms "a", "the" and "the" used in the embodiments of the present invention and the appended claims are also intended to include plural forms, unless the context clearly indicates otherwise.

[0059] It should be understood that the term "and / or" as used herein simply describes a relationship between associated objects, indicating that three possible relationships exist. For example, "A and / or B" can represent: A alone, A and B together, or B alone. Furthermore, the character " / " in this document generally indicates an "or" relationship between the associated objects.

[0060] The present invention provides a display panel. Figure 1 As shown, Figure 1 This is a schematic diagram of a display panel provided in an embodiment of the present invention. Display panel 100 includes: a substrate 1; and a plurality of sub-pixels 2 arranged in an array along a first direction h11 and a second direction h12, located on the same side of substrate 1. Sub-pixels 2 include a first sub-pixel 21, a second sub-pixel 22, and a third sub-pixel 23. The first sub-pixel 21, the second sub-pixel 22, and the third sub-pixel 23 each emit light of different colors. For example, the first sub-pixel 21 includes a red sub-pixel, the second sub-pixel 22 includes a blue sub-pixel, and the third sub-pixel 23 includes a green sub-pixel.

[0061] like Figure 1As shown, the i-th row of sub-pixels 11_i includes first sub-pixels 21 and third sub-pixels 23 arranged alternately along the first direction h11; the i+1-th row of sub-pixels 11_i+1 includes third sub-pixels 23 and second sub-pixels 22 arranged alternately along the first direction h11; the j-th column of sub-pixels 12_j includes first sub-pixels 21 and third sub-pixels 23 arranged alternately along the second direction h12; the j+1-th column of sub-pixels 12_j+1 includes third sub-pixels 23 and second sub-pixels 22 arranged alternately along the second direction h12; the second direction h12 intersects the first direction h11; wherein i and j are both arbitrary positive integers. The intersection of the second direction h12 and the first direction h11 defines the plane where the substrate 1 is located. Figure 1 As an illustration, the second direction h12 is perpendicular to the first direction h11.

[0062] For example, Figure 1 As shown, the display panel 100 further includes a partition portion 3 , which includes a first partition portion 31 and a second partition portion 32 . The first partition portion 31 at least partially surrounds the first sub-pixel 21 , and the second partition portion 32 at least partially surrounds the second sub-pixel 22 .

[0063] For example, Figure 2 As shown, Figure 2 A cross-sectional schematic diagram of a display panel provided in an embodiment of the present invention, wherein the sub-pixel 2 includes a first electrode 201, a light-emitting layer 203, a second electrode 202, and a common layer 204. The partition portion 3 is located on the side of the common layer 204 close to the substrate 1. Optionally, the common layer 204 includes a first sub-common layer 2041 and a second sub-common layer 2042, wherein the first sub-common layer 2041 is located between the first electrode 201 and the light-emitting layer 203, and the second sub-common layer 2042 is located between the second electrode 202 and the light-emitting layer 203. Optionally, the common layer 204 can be prepared using an open mask (Common Mask). The light-emitting layer 203 can be prepared using a fine metal mask (Fine Meta l Mask, abbreviated as FMM).

[0064] Optional, such as Figure 2 As shown, the display panel 100 further includes a pixel definition layer 8 , and the pixel definition layer 8 includes an opening 80 , and the opening 80 exposes at least a portion of the first electrode 201 .

[0065] In the embodiment of the present invention, the first electrodes 201 of different sub-pixels 2 are independent of each other, and the second electrodes 202 of the plurality of sub-pixels 2 are electrically connected to each other.

[0066] Optionally, the first electrode 201 includes an anode, and the second electrode 202 includes a cathode. The first sub-common layer 2041 includes a hole injection layer and / or a hole transport layer. The second sub-common layer 2042 includes an electron injection layer and / or an electron transport layer.

[0067] like Figure 2 As shown, the partition portion 3 includes a raised portion 301 that is raised toward the side away from the substrate 1. Optionally, the raised portion 301 includes a first side surface S11 and a first bottom surface S12 on the side close to the substrate 1. In the embodiment of the utility model, the angle between the first side surface S11 and the first bottom surface S12 toward the inside of the raised portion 301 can be an obtuse angle, that is, the area of ​​the side of the raised portion 301 away from the substrate 1 is larger than the area of ​​the side close to the substrate 1. Based on this setting, the common layer 204 formed after the raised portion 301 will not be formed (or continuously formed) on the first side surface S11 and will be disconnected at the raised portion 301, thereby isolating the path for the lateral leakage current to be transmitted between two adjacent sub-pixels 2 through the common layer 204, thereby suppressing the transmission of the lateral leakage current and improving the display effect.

[0068] In another optional embodiment, as Figure 3 As shown, Figure 3 This is a schematic cross-sectional view of another display panel provided by an embodiment of the present invention. In this embodiment of the present invention, the angle between the first side surface S11 and the first bottom surface S12, which faces the interior of the raised portion 301, can also be acute. That is, the area of ​​the side of the raised portion 301 away from the substrate 1 is smaller than the area of ​​the side closer to the substrate 1. Based on this arrangement, the common layer 204 formed after the raised portion 301 is formed on the first side surface S11. Due to the morphological characteristics of the raised portion 301, the path for lateral leakage current to be transmitted between two adjacent sub-pixels 2 through the common layer 204 can be extended, thereby suppressing the transmission of lateral leakage current and improving the display effect.

[0069] In another optional embodiment, as Figure 4 As shown, Figure 4 A cross-sectional schematic diagram of another display panel provided by an embodiment of the present invention, wherein the partition portion 3 includes a recessed portion 302 recessed toward one side of the substrate 1, and the recessed portion 302 includes a second side surface S21 and a second bottom surface S22 close to the side of the substrate 1, as shown in FIG. Figure 4 As shown, the angle between the second side surface S21 and the second bottom surface S22 is an obtuse angle. Based on this arrangement, the common layer 204 formed after the recessed portion 302 is formed on the second side surface S21 of the recessed portion 302. Due to the morphological characteristics of the recessed portion 302, the path for the lateral leakage current to be transmitted between two adjacent sub-pixels 2 through the common layer 204 can be extended, thereby suppressing the transmission of the lateral leakage current and improving the display effect.

[0070] In another optional embodiment, as Figure 5 As shown, Figure 5This is a cross-sectional schematic diagram of another display panel provided by an embodiment of the present invention. In this embodiment, the angle between the second side surface S21 and the second bottom surface S22 can also be acute. Based on this arrangement, the common layer 204 formed after the recess 302 cannot be formed on the second side surface S21, thus being disconnected at the recess 302. This can block the path for lateral leakage current to be transmitted between two adjacent sub-pixels 2 through the common layer 204, thereby suppressing the transmission of lateral leakage current and improving the display effect.

[0071] For example, Figure 4 and Figure 5 As shown, in the embodiment of the present invention, the recessed portion 302 can be opened in the pixel definition layer 8 .

[0072] For example, when preparing the display panel, the pixel definition layer 8 can be prepared after the first electrode 201 is prepared, and then the support portion 5 and the opening 80 can be prepared by a half-grayscale mask. After the support portion 5 and the opening 80 are prepared, a hard mask layer can be prepared on the side of the support portion 5 away from the substrate 1. The hard mask layer includes multiple regions with different transmittances. Specifically, the transmittance of the region corresponding to the partition portion 3 in the hard mask layer is different from the transmittance of other positions. Under the blocking effect of the hard mask layer, the pixel definition layer 8 is etched, for example, by dry etching. This method is conducive to increasing the depth of the recessed portion 302 formed on the pixel definition layer 20. When the common layer is subsequently formed, the amount of the common layer that can be accommodated in the recessed portion 302 will be larger, which is conducive to extending the layout path of the common layer and the transmission path of the electrical signal. Therefore, it is conducive to blocking the leakage transmission path and effectively avoiding the problem of sub-pixels secretly lighting up.

[0073] Optionally, the hard mask layer may be removed after forming the recessed portion 302. Methods for removing the hard mask layer include wet etching.

[0074] For example, the hard mask layer may be an IZO layer.

[0075] In another optional embodiment, after the pixel definition layer 8 is prepared, the embodiment of the present invention can also use photoresist to cover the surface of the pixel definition layer 8, and then use patterning processes such as exposure, development, and etching to form the recessed portion 302 in the pixel definition layer 8. Based on this method, the sidewalls and top corner edges of the recessed portion 302 can be made smoother, reducing defects.

[0076] For example, Figure 4 and Figure 5As shown, the embodiment of the present invention can make the depth of the recessed portion 302 less than the thickness of the pixel definition layer 8, that is, the second bottom surface S22 of the recessed portion 302 is located inside the pixel definition layer 8. Alternatively, the embodiment of the present invention can also make the depth of the recessed portion 302 equal to the thickness of the pixel definition layer 8, that is, the recessed portion 302 passes through the pixel definition layer 8. In another optional embodiment, the embodiment of the present invention can also make the depth of the recessed portion 302 greater than the thickness of the pixel definition layer 8, that is, the recessed portion 302 passes through the pixel definition layer 8, and make the recessed portion 302 continue to be recessed toward the side close to the substrate 1, so that the second bottom surface S22 of the recessed portion 302 is located in other organic layers between the pixel definition layer 8 and the substrate 1. For example, a planarization layer may also be included between the pixel definition layer 8 and the substrate 1. The embodiment of the present invention can make the second bottom surface S22 of the recessed portion 302 located inside the planarization layer.

[0077] Illustratively, in the embodiment of the present invention, the first partition portion 31 and the second partition portion 32 may have the same shape. For example, both may be convex portions, or both may be concave portions.

[0078] Alternatively, in the embodiment of the present invention, the first partition portion 31 and the second partition portion 32 may have different shapes. For example, one of the first partition portion 31 and the second partition portion 32 may be a raised portion and the other may be a recessed portion.

[0079] In the embodiment of the present utility model, Figure 1 As shown, the first partition portion 31 includes a first notch 41 and the second partition portion 32 includes a second notch 42. That is, the first partition portion 31 is a non-enclosed figure including the first notch 41, and the second partition portion 32 is a non-enclosed figure including the second notch 42.

[0080] When the partition part 3 is set to include Figure 2 and Figure 3 The raised portion 301 or Figure 4 and Figure 5 In the case of the recessed portion 302 shown, the first partition portion 31 includes a first notch 41, which means that the first partition portion 31 is a substantially flat structure without a protrusion or a recessed portion at the location of the first notch 41. The second partition portion 32 includes a second notch 42, which means that the second partition portion 32 is a substantially flat structure without a protrusion or a recessed portion at the location of the second notch 42.

[0081] The setting of the first notch 41 and the second notch 42 can avoid the second electrode 202 formed after the above-mentioned first partition portion 31 and the second partition portion 32 from being disconnected or thinned at the first notch 41 and the second notch 42. The second electrode 202 can be formed into a continuous structure with a large thickness at the first notch 41 and the second notch 42, which is beneficial to reducing the voltage drop of the signal transmitted by the second electrode 202 during the transmission process, improving the voltage uniformity of the second electrode 202 in the display area, and improving the display uniformity of the display panel.

[0082] For example, Figure 1 As shown, the display panel 100 further includes a plurality of support portions 5; along the third direction h13, at least part of the support portions 5 is located between the first sub-pixel 21 and the adjacent second sub-pixel 22, and, along the fourth direction h14, at least part of the support portions 5 is located between two adjacent third sub-pixels 23; the third direction h13 and the fourth direction h14 are both parallel to the plane where the substrate 1 is located, and the third direction h13 intersects with the first direction h11 and the second direction h12 respectively; the fourth direction h14 intersects with the first direction h11 and the second direction h12 respectively; the third direction h13 intersects with the fourth direction h14; Figure 1 As an illustration, the third direction h13 and the fourth direction h14 are perpendicular.

[0083] Optionally, the support portion 5 may be used to support a mask used in the manufacturing process of the display panel 100 .

[0084] For example, Figure 6 As shown, Figure 6 A cross-sectional diagram of a first sub-pixel, a second sub-pixel, and a support portion provided by an embodiment of the present invention. Along the third direction h13, the support portion 5 is located between the first sub-pixel 21 and the second sub-pixel 22. Along the direction h2 perpendicular to the plane of the substrate 1, the support portion 5 protrudes from the surface of the pixel definition layer 8 toward the side away from the substrate 1. For example, when the partition portion 3 is configured to include Figure 2 and Figure 3 When the raised portion 301 shown is combined Figure 6 and Figure 3 As shown, the height H5 of the support portion 5 is greater than or equal to the height H301 of the protrusion 301 .

[0085] In an optional embodiment, as Figure 6As shown, the support portion 5 includes a third side surface S51 and a third bottom surface S52 on the side closer to the substrate 1. In this embodiment of the utility model, the angle between the third side surface S51 and the third bottom surface S52, facing the interior of the support portion 5, can be acute. That is, the area of ​​the support portion 5 away from the substrate 1 is smaller than the area of ​​the side closer to the substrate 1. The common layer 204 formed after the support portion 5 can be formed on the third side surface S51.

[0086] In the embodiment of the present invention, the area between adjacent first sub-pixels 21 and second sub-pixels 22 includes at least one of the non-notch portion of the first partition portion 31, the non-notch portion of the second partition portion 32, and the support portion 5. The area defined by "the area between adjacent first sub-pixels 21 and second sub-pixels 22" refers to the area within a quadrilateral defined by two vertices of the first sub-pixel 21 and two vertices of the second sub-pixel 22 adjacent to the first sub-pixel 21. The two vertices of the first sub-pixel 21 are the two vertices of the first sub-pixel 21 that are farthest apart in a direction intersecting the arrangement direction of the first sub-pixel 21 and the second sub-pixel 22, and the two vertices of the second sub-pixel 22 are the two vertices of the second sub-pixel 22 that are farthest apart in a direction intersecting the arrangement direction of the first sub-pixel 21 and the second sub-pixel 22.

[0087] For example, Figure 1 As shown, the first notch 41, the second notch 42, and the support portion 5 are included between the adjacent portions of the first sub-pixel 21 and the second sub-pixel 22 in the third direction h13. That is, the first notch 41, the second notch 42, and the support portion 5 are included only. The first notch 41, the second notch 42, and the support portion 5 are included between the adjacent portions of the first sub-pixel 21 and the second sub-pixel 22 in the third direction h13. This means that the first notch 41, the second notch 42, and the support portion 5 are located within the first area AA1. The first area AA1 is a quadrilateral with four vertices of the quadrilateral, the two vertices of the first sub-pixel 21, and the two vertices of the second sub-pixel 22. The two vertices of the first sub-pixel 21 are the two vertices that are farthest apart from each other in the fourth direction h14, and the two vertices of the second sub-pixel 22 are the two vertices that are farthest apart from each other in the fourth direction h14. Figure 1 The outline of the first area AA1 is indicated by a dashed line.

[0088] Another portion of the first and second sub-pixels 21 and 22 adjacent to each other in the third direction h13 does not include the support portion 5 and the non-notch portion of the first partition portion 31 , but only includes the non-notch portion of the second partition portion 32 .

[0089] In another optional embodiment, as Figure 7 As shown, Figure 7 This is a schematic diagram of another display panel provided by an embodiment of the present invention. The first sub-pixel 21 and the second sub-pixel 22 adjacent to each other in the third direction h13 include a first notch 41, a second notch 42 and a support portion 5, that is, only the support portion 5 is included.

[0090] Another portion of the first and second sub-pixels 21 and 22 adjacent to each other in the third direction h13 does not include the non-notch portion of the supporting portion 5 and the second partition portion 32 , but only includes the non-notch portion of the first partition portion 31 .

[0091] The first notch 41, the second notch 42, and the support portion 5 are included between the adjacent portions of the first sub-pixel 21 and the second sub-pixel 22 in the fourth direction h14. That is, only the support portion 5 is included. The first notch 41, the second notch 42, and the support portion 5 are included between the adjacent portions of the first sub-pixel 21 and the second sub-pixel 22 in the fourth direction h14. This means that the first notch 41, the second notch 42, and the support portion 5 are located within the first area AA1. The first area AA1 is shaped like a quadrilateral, with the four vertices of the quadrilateral being the two vertices of the first sub-pixel 21 and the two vertices of the second sub-pixel 22. The two vertices of the first sub-pixel 21 are the two vertices that are farthest apart from each other in the third direction h13, and the two vertices of the second sub-pixel 22 are the two vertices that are farthest apart from each other in the third direction h13. Figure 7 The outline of the first area AA1 is indicated by a dashed line.

[0092] Another portion of the adjacent first sub-pixels 21 and second sub-pixels 22 in the fourth direction h14 does not include the supporting portion 5 and the non-notch portion of the second partition portion 32 , that is, only includes the non-notch portion of the first partition portion 31 .

[0093] In another optional embodiment, as Figure 8 As shown, Figure 8 This is a schematic diagram of another display panel provided by an embodiment of the present invention, wherein the first sub-pixel 21 and the second sub-pixel 22 adjacent to each other in the third direction h13 include a first notch 41, a second notch 42 and a support portion 5, that is, only the support portion 5 is included.

[0094] Another portion of the first and second sub-pixels 21 and 22 adjacent to each other in the third direction h13 does not include the support portion 5 but only includes the non-notch portion of the first partition portion 31 and the non-notch portion of the second partition portion 32 .

[0095] In another optional embodiment, as Figure 9 As shown, Figure 9 A schematic diagram of another display panel provided for an embodiment of the present invention, wherein the adjacent portions between the first sub-pixel 21 and the second sub-pixel 22 in the third direction h13 include a first notch 41, a non-notch portion of the second partition portion 32, and a supporting portion 5, that is, only the non-notch portion of the second partition portion 32 and the supporting portion 5.

[0096] Another portion of the first and second sub-pixels 21 and 22 adjacent to each other in the third direction h13 does not include the support portion 5 and the non-notch portion of the first partition portion 31 , but only includes the non-notch portion of the second partition portion 32 .

[0097] In another optional embodiment, as Figure 10 As shown, Figure 10 This is a schematic diagram of another display panel provided by an embodiment of the present invention. A portion of the display panel between a first sub-pixel 21 and a second sub-pixel 22 adjacent to each other in the third direction h13 includes the second notch 42, the non-notch portion of the first partition 31, and the support portion 5. That is, the portion includes only the non-notch portion of the first partition 31 and the support portion 5. Another portion of the display panel between a first sub-pixel 21 and a second sub-pixel 22 adjacent to each other in the third direction h13 does not include the support portion 5 or the non-notch portion of the second partition 32, but only the non-notch portion of the first partition 31.

[0098] In another optional embodiment, as Figure 11 As shown, Figure 11 This is a schematic diagram of another display panel provided by an embodiment of the present invention. A portion of the space between adjacent first and second sub-pixels 21 and 22 in the third direction h13 includes the non-notched portion of the first partition 31, the non-notched portion of the second partition 32, and the support portion 5. Another portion of the space between adjacent first and second sub-pixels 21 and 22 in the third direction h13 does not include the support portion 5 and includes only the non-notched portion of the first and second partitions 31 and 32.

[0099] As mentioned above, the provision of the first notch 41 and the second notch 42 can prevent the second electrode 202 from being thinned or broken at the locations of the first notch 41 and the second notch 42 , thereby improving the connection reliability of the second electrode 202 .

[0100] When setting the above-mentioned first notch 41, second notch 42 and support portion 5, the embodiment of the present invention ensures that the positions of the first notch 41, second notch 42 and support portion 5 are comprehensively considered while ensuring the connection reliability of the second electrode 202 by ensuring that the adjacent first sub-pixel 21 and second sub-pixel 22 include at least one of the non-notch portion of the first partition portion 31, the non-notch portion of the second partition portion 32 and the support portion 5. This can avoid simultaneously setting the first notch and the second notch between the first sub-pixel and the second sub-pixel that are not adjacent to the support portion, and can ensure that at least one suppression structure for extending or isolating the conductive path of the lateral leakage current is included between the first sub-pixel 21 and the second sub-pixel 22 that are not adjacent to the support portion 5, so as to suppress the transmission of the lateral leakage current between the first sub-pixel 21 and the second sub-pixel 22, reduce the possibility of crosstalk between the first sub-pixel 21 and the second sub-pixel 22, and reduce the possibility of the first sub-pixel 21 and the second sub-pixel 22 being secretly bright, thereby optimizing the low grayscale display effect of the display panel and improving the display quality of the display panel. For example, when the first sub-pixel 21 is a red sub-pixel and the second sub-pixel 22 is a blue sub-pixel, based on the above-mentioned setting method provided by the embodiment of the present invention, when displaying a blue picture, the possibility of the red sub-pixel being secretly bright can be reduced, thereby improving the display quality of the blue picture.

[0101] In the embodiment of the present utility model, combined with Figure 1 and Figure 12A As shown, Figure 12A An enlarged schematic diagram of a sub-pixel including a protrusion and a main body is provided in an embodiment of the present invention. At least one of the first sub-pixel 21 and the second sub-pixel 22 includes a protrusion 201 and a main body 202. The edge of the protrusion 201 away from the main body 202 includes an arc segment C, and the arc segment C protrudes toward the side away from the main body 202.

[0102] Figure 1 、 Figure 7 、 Figure 8 、 Figure 9 、 Figure 10 and Figure 11 As an example, the second sub-pixel 22 is configured to include a protruding portion 201 and a main portion 202 .

[0103] like Figure 12A As shown, the second sub-pixel 22 includes a virtual circumscribed quadrilateral 20, which includes a first virtual side DE1, a second virtual side DE2, a third virtual side DE3, and a fourth virtual side DE4. The third virtual side DE3 connects the first virtual side DE1 and the second virtual side DE2 on the same side, and the fourth virtual side DE4 is arranged opposite the third virtual side DE3. The first virtual side DE1, the second virtual side DE2, the third virtual side DE3, and the fourth virtual side DE4 are all straight line segments.

[0104] For example, Figure 12A As shown, the main body 202 includes a first side ZE1 and a second side ZE2; the protruding portion 201 includes a third side ZE3, and the third side ZE3 includes the arc segment C mentioned above.

[0105] In the embodiment of the present invention, the first virtual edge DE1 partially overlaps with the first edge ZE1, that is, at least one point of the first edge ZE1 is located on the first virtual edge DE1; Figure 12A As shown, all points on the first side ZE1 may be located on the first virtual side DE1.

[0106] The second virtual edge DE2 partially overlaps with the second edge ZE2, that is, at least one point of the second edge ZE2 is located on the second virtual edge DE2; Figure 12A As shown, all points on the second edge ZE2 may be located on the second virtual edge DE2.

[0107] At least one point of the third side ZE3 coincides with the third virtual side DE3, such as Figure 12A As shown, the third side ZE3 and the third virtual side DE3 are tangent to each other at the first point P11.

[0108] Based on this arrangement, the orthographic projection of at least one of the first sub-pixel 21 and the second sub-pixel 22 on the plane where the substrate 1 is located can be located within the corresponding virtual circumscribed quadrilateral 20 .

[0109] It should be noted that the shapes of the sub-pixels mentioned in the embodiments of the present invention refer to the shapes of the openings 80 opened in the pixel definition layer 8. For example, Figure 2 As shown, when the opening 80 is set to a shape in which the area of ​​the side away from the substrate 1 is larger than the area of ​​the side close to the substrate 1, the shape of each sub-pixel refers to the shape of the area corresponding to the lower edge of the opening 80, that is, the shape of the area where the light-emitting layer in contact with the first electrode 201 is located, that is, the shape of the light-emitting area of ​​the sub-pixel.

[0110] In the embodiment of the present invention, by configuring at least one of the first sub-pixel 21 and the second sub-pixel 22 to include a protrusion 201 and a main portion 202, and configuring the edge of the protrusion 201 away from the main portion 202 to include an arc segment C, the area of ​​the corresponding sub-pixel can be reduced compared to the case where the shape of either the first sub-pixel 21 or the second sub-pixel 22 is configured to be a circumscribed virtual quadrilateral. For example, configuring the first sub-pixel 21 to include a protrusion can reduce the area of ​​the first sub-pixel 21; configuring the second sub-pixel 22 to include a protrusion can reduce the area of ​​the second sub-pixel 22; and configuring both the first sub-pixel 21 and the second sub-pixel 22 to include a protrusion 201 can reduce the areas of both the first sub-pixel 21 and the second sub-pixel 22. The space between the protrusion 201 and the circumscribed virtual quadrilateral corresponding to the sub-pixel 2 represents the portion with reduced area. After the area of ​​a sub-pixel 2 is reduced, the distance between the sub-pixel 2 and another adjacent sub-pixel 2 can be increased. This, on the one hand, increases the transmission path of the lateral leakage current between the two sub-pixels 2, thereby reducing crosstalk. On the other hand, it also leaves space for the installation of the first partition 31, the second partition 32, and the support 5, thereby reducing the process difficulty of installing the first partition 31, the second partition 32, or the support 5 between the two sub-pixels. For example, the partition 3 and the support 5 can be kept at a certain distance from the first sub-pixel 21 and the second sub-pixel 22, respectively, to prevent the partition 3 or the support 5 from falling into the pixel opening due to process errors or subsequent external forces, thereby affecting the display.

[0111] On the other hand, while ensuring that the minimum spacing between two adjacent sub-pixels remains unchanged, compared to the case where the shape of the first sub-pixel 21 or the second sub-pixel 22 is set to be square, the embodiment of the utility model configures the first sub-pixel 21 or the second sub-pixel 22 to include a protruding portion, which is equivalent to cutting the arc edge of the circumscribed virtual quadrilateral corresponding to the first sub-pixel 21 or the second sub-pixel 22. Taking the case of cutting the arc edge of the circumscribed virtual quadrilateral corresponding to the second sub-pixel 22 as an example, after cutting the arc edge, at least one vertex of the second sub-pixel 22 is retracted toward the center of the circumscribed virtual quadrilateral close to the second sub-pixel 22, thereby leaving space for another sub-pixel adjacent to the second sub-pixel 22 to expand outward, thereby increasing the area of ​​the expanded sub-pixel and improving its aperture ratio.

[0112] Specifically, refer to Figure 12B As shown, Figure 12BThis is a schematic diagram of a display panel in the related art, wherein the shape of the first sub-pixel 21 and the shape of the second sub-pixel 22 are both squares, the first sub-pixels 21 and the second sub-pixels 22 are alternately arranged along the third direction h13 and the fourth direction h14, respectively, the centers (i.e., centers of gravity) of two adjacent first sub-pixels 21 and second sub-pixels 22 constitute a virtual square Qs, a third sub-pixel 23 is located in the virtual square Qs, and the center (i.e., center of gravity) of the third sub-pixel 23 coincides with the center of the virtual square Qs.

[0113] Assume that the pixel center pitch (i.e., pixel pitch) PL of the first sub-pixel 21 and the second sub-pixel 22 is 55 μm, the minimum opening pitch t1 between the first sub-pixel 21 and the second sub-pixel 22 is 25 μm, the minimum opening pitch t2 between the third sub-pixel 23 and the first sub-pixel 21 is 18 μm, the minimum opening pitch t3 between the third sub-pixel 23 and the second sub-pixel 22 is 18 μm, the minimum opening pitch t4 between two adjacent third sub-pixels 23 is 35 μm, and the distance Xr from the vertex to the center of the first sub-pixel 21 is 10.98 μm. Calculation shows that the area S1 of the first sub-pixel 21 is 241.12 μm. 2 , the area S2 of the second sub-pixel 22 is 723.52 μm 2 , the area S3 of the third sub-pixel 23 is 308.15 μm 2 For a pixel unit including a first sub-pixel 21, a second sub-pixel 22 and two third sub-pixels 23, the opening area of ​​the pixel unit is Stotal = S1 + S2 + 2S3 = 1580.94 μm 2 .

[0114] refer to Figure 12C and Figure 12D As shown, Figure 12C This is an enlarged schematic diagram of another sub-pixel including a protruding portion and a main portion provided by an embodiment of the present invention. Figure 12D A display panel and Figure 12B A comparative schematic diagram of a display panel in the related art is shown, Figure 12D The shapes of the first sub-pixel 21 and the second sub-pixel 22 are in accordance with Figure 12C The shape of the sub-pixel is designed, wherein the sub-pixel includes a protruding portion 201 and a main portion 202, the arc segment C includes a first arc segment C1 and a second arc segment C2, and the edge of the protruding portion 201 away from the main portion 202 also includes a straight line segment L connecting the first arc segment C1 and the second arc segment C2, and the length of the first arc segment C1 is greater than the length of the second arc segment C2. The two endpoints of the first arc segment C1 are P1 and P2, the two endpoints of the second arc segment C2 are P3 and P4, and the two endpoints of the straight line segment L are P2 and P3.

[0115] exist Figure 12D In the embodiment, the minimum opening spacing g1 between the first sub-pixel 21 and the second sub-pixel 22 is 25μm, the minimum opening spacing g2 between the third sub-pixel 23 and the first sub-pixel 21 is 18μm, the minimum opening spacing g3 between the third sub-pixel 23 and the second sub-pixel 22 is 18μm, and the minimum opening spacing g4 between two adjacent third sub-pixels 23 is 35μm. That is to say, the minimum opening spacing between any two of the first sub-pixel 21, the second sub-pixel 22 and the third sub-pixel 23 in the embodiment of the utility model and the minimum spacing between two adjacent third sub-pixels 23 are set to be equal to the corresponding minimum opening spacing in the related art.

[0116] It should be noted that, in the related art, since the first sub-pixel 21 and the second sub-pixel 22 are both square in shape, the minimum opening distance between them is the distance along the center line of the sub-pixels (the side of the virtual square Qs). Figure 12A and Figure 12C After the above-mentioned convex portion 201 is included, the minimum opening distance g1 of the first sub-pixel 21 and the second sub-pixel 22 is not equal to the distance between the two on the side of the virtual square Qs. Figure 12C and Figure 12D As shown, the minimum opening spacing g1 between the first sub-pixel 21 and the second sub-pixel 22 adjacent to it in the third direction h13 is the distance between the point P4 of the first sub-pixel 21 and the right-angled vertex of the second sub-pixel 22; the minimum opening spacing g1 between the first sub-pixel 21 and the second sub-pixel 22 adjacent to it in the fourth direction h14 is the distance between the point P4 of the second sub-pixel 22 and the right-angled vertex of the first sub-pixel 21; the minimum opening spacing between any other adjacent first sub-pixels 21 and second sub-pixels 22 is also the same and will not be repeated.

[0117] by Figure 12C For example, the first sub-pixel 21 corresponds to Xa=Xb=2.8μm, the length of the straight line segment L from P2 to P3 is 5μm, the second sub-pixel 22 corresponds to Xa=Xb=2.7μm, the length of the straight line segment L from P2 to P3 is 6μm, and the calculation results are: S1=261.56μm 2 , S2=799.45μm 2 , S3=279.84μm 2 The total opening area of ​​a pixel unit is Stotal = S1 + S2 + 2S3 = 1620.69 μm 2 .

[0118] It can be seen that the minimum distance between any two adjacent sub-pixels is Figure 12B On the basis of maintaining consistency with the related technologies shown, compared with the case where the shapes of the first sub-pixel 21 and the second sub-pixel 22 are both set to be squares, the setting method provided by the embodiment of the present invention can increase the areas of the first sub-pixel 21 and the second sub-pixel 22, improve the aperture ratio of the two, and the total aperture ratio of the pixel unit including a first sub-pixel 21, a second sub-pixel 22 and two third sub-pixels 23 can also be improved.

[0119] Furthermore, in the embodiment of the present invention, the design of the third sub-pixel 23 is not only affected by g2 and g3 described above, but also by the spacing of the mask openings of the fine metal mask (FMM). The spacing of the mask openings of the fine metal mask is also referred to as the rib width of the fine metal mask. To ensure the strength of the fine metal mask, the spacing between the mask openings is limited. Therefore, the distance between two adjacent third sub-pixels 23 in the third direction h13 and the fourth direction h14 is also limited. This limitation does not shrink inward due to the expansion of the first sub-pixel 21 and the second sub-pixel 22. In other words, compared to the related art, the third sub-pixel 23 in the embodiment of the present invention does not shrink inward along the two opposite sides of the third direction h13 and the two opposite sides along the fourth direction h14. Therefore, even in order to ensure that the minimum opening spacing g2 between the third sub-pixel 23 and the first sub-pixel 21, and the minimum opening spacing g3 between the third sub-pixel 23 and the second sub-pixel 22 can respectively satisfy g2≥t2 and g3≥t3, when the first sub-pixel 21 and the second sub-pixel 22 expand outward, at least part of the sides of the third sub-pixel 23 located in the virtual square Qs will be retracted, thereby reducing the opening area of ​​the third sub-pixel 23. However, based on the setting method provided in the embodiment of the present invention, it is possible to avoid causing the two opposite sides of the third sub-pixel 23 along the third direction h13 and the two opposite sides along the fourth direction h14 to retract, and it is possible to avoid setting the opening area of ​​the third sub-pixel 23 too small, and it can be ensured that the total aperture ratio within a pixel unit including one first sub-pixel 21, one second sub-pixel 22 and two third sub-pixels 23 is still increased compared with the related art.

[0120] In summary, compared with the related art, the pixel design method provided in the embodiment of the present invention does not increase the process difficulty, such as on the basis of making the relevant process parameters (such as the minimum opening spacing between adjacent sub-pixels, FMM r ib, etc.) consistent with the existing technology or still maintaining design redundancy, the total aperture ratio of the pixel unit including a first sub-pixel 21, a second sub-pixel 22 and two third sub-pixels 23 can be increased, which is beneficial to improving the display effect and display quality of the display panel.

[0121] For example, Figure 1 、 Figure 7 、 Figure 8 、 Figure 9 、 Figure 10 and Figure 11 As shown, the first sub-pixel 21 includes the first and second sub-pixels 211 , and the supporting portion 5 is located between the first and second sub-pixels 211 and the second sub-pixel 22 .

[0122] like Figure 1 、 Figure 7 、 Figure 8 、 Figure 9 、 Figure 10 and Figure 11 As shown, along the third direction h13, at least part of the support portion 5 is located between the first sub-pixel 211 and the second sub-pixel 22. Figure 7 As shown, along the fourth direction h14 , a portion of the support portion 5 is located between the first sub-pixel 211 and the second sub-pixel 22 .

[0123] The first sub-pixel 211 includes a vertex angle A, which is formed by two adjacent sides of the first sub-pixel 211. Either of the two adjacent sides may be a straight line segment or an arc segment. Figure 1 、 Figure 7 、 Figure 8 、 Figure 9 、 Figure 10 and Figure 11 It is assumed that the side of the first sub-pixel 211 includes four straight line segments for illustration.

[0124] In the embodiment of the present invention, the first partition portion 31 includes a first sub-partition portion 311 , and the first sub-partition portion 311 at least partially surrounds the first sub-pixel 211 .

[0125] Optional, such as Figure 1 、 Figure 7 、 Figure 8 、 Figure 9 and Figure 10 As shown, the first sub-partition portion 311 includes a first notch 41 corresponding to the vertex angle A of the first sub-pixel 211. The correspondence between the vertex angle A of the first sub-pixel 211 and the first notch 41 means that the line connecting the center of the first notch 41 and the centroid of the virtual circumscribed quadrilateral of the first sub-pixel 211 passes through the vertex angle A. The center of the first notch 41 refers to the midpoint of the line connecting the two endpoints of the first partition portion 31 forming the first notch 41.

[0126] In the embodiment of the present invention, by arranging the first notch 41 to correspond to the top corner A of the first sub-pixel 211, the second electrode 202 can have a greater thickness at the periphery of the top corner A of the first sub-pixel 211, so that the second electrode 202 of the first sub-pixel 211 is well connected at the periphery of the top corner A of the first sub-pixel 211.

[0127] Moreover, because the first sub-pixel 211 is arranged close to the support portion 5, by forming the first notch 41 corresponding to the top angle A, that is, the first sub-partition portion 311 is not arranged at the position where the first notch 41 is located, the space available for setting the support portion 5 can be increased on the basis of a certain distance between the first sub-pixel 211 and the second sub-pixel 22 adjacent thereto, which is conducive to reducing the difficulty of setting the support portion 5.

[0128] It is understandable that the center of gravity of the virtual circumscribed quadrilateral mentioned in the embodiment of the present invention can be defined as the center point of mass distribution of the geometric shape of the virtual circumscribed quadrilateral, that is, the center of mass. If the geometric shape of the virtual circumscribed quadrilateral is a regular geometric shape, then the geometric center of the virtual circumscribed quadrilateral and its center of gravity coincide. For example, if the shape of the virtual circumscribed quadrilateral is a parallelogram, the intersection of the two diagonals of the parallelogram is both its geometric center and its center of gravity. If the geometric shape of the virtual circumscribed quadrilateral is an asymmetric irregular geometric shape, then its center of gravity can be determined by relevant technologies, but its geometric center is more difficult to determine. In this case, the relative positional relationship between the geometric center and the center of gravity of the virtual circumscribed quadrilateral is more difficult to determine.

[0129] It should be noted that regular figures (regular geometric shapes) in the present invention meet at least one of the following conditions: 1) centrally symmetrical figures; 2) axially symmetrical figures with two or more axes of symmetry. For example, ellipses, parallelograms (non-rectangular and non-rhombus), circles, rounded rectangles, regular polygons, rectangles, rhombuses, etc. are all regular figures. For centrally symmetrical figures, the central symmetry point is the center (center of gravity); for axially symmetrical figures with two or more axes of symmetry, the intersection of the two axes of symmetry is the center (center of gravity). Figures other than regular figures are irregular figures.

[0130] For example, Figure 13 As shown, Figure 13 This is an enlarged schematic diagram of a first sub-pixel, a first partition portion, and a support portion provided by an embodiment of the present invention. The first sub-pixel 211 includes at least two vertex angles A. Figure 13 The shape of the first sub-pixel 211 is designed as a quadrilateral as an example, wherein two adjacent sides of the first sub-pixel 211 intersect to form the above-mentioned vertex angle A. Figure 13In the illustrated embodiment, the first sub-pixel 211 includes four vertex angles A. The first sub-partitioning portion 311 includes at least two first notches 41, and the two first notches 41 correspond to different vertex angles A. Along the third direction h13, one of the first notches 41 is located on the side of the first sub-pixel 211 close to the support portion 5, and the other first notch 41 is located on the side of the first sub-pixel 211 away from the support portion 5. That is, the two first notches 41 and the support portion 5 are arranged along the third direction h13. Figure 13 As shown, the line connecting the center of gravity of the virtual circumscribed quadrilateral of the first sub-pixel 211 and the center of gravity of the support portion 5 passes through the two first gaps 41 respectively.

[0131] The first notch 41 disposed near the support portion 5 avoids the need for a raised or recessed portion around the periphery of the top corner A on the side of the first sub-pixel 211 near the support portion 5, thus preventing the raised or recessed portion from occupying space on the support portion 5 and reducing the difficulty of installing the support portion 5. Furthermore, the provision of the first notch 41 farther from the support portion 5 increases the number of first notches 41, thereby increasing the number of reliable connection locations for the second electrode and, consequently, increasing the conductive paths for the signal transmitted by the second electrode. For example, at least in the direction in which the two first notches 41 are arranged, the signal transmitted by the second electrode can be smoothly transmitted.

[0132] Optional, such as Figure 13 As shown, the distance between the two end points of the first notch 41 away from the support portion 5 is S111, and the distance between the two end points of the first notch 41 close to the support portion 5 is S112, where S111 ≤ S112. Based on this arrangement, by increasing the distance between the two end points of the first notch 41 close to the support portion 5, the distance between the support portion 5 and the non-notch portion of the first sub-partition portion 311 can be increased, thereby further reducing the difficulty of setting up the support portion 5.

[0133] For example, Figure 13 As shown, the length of the support portion 5 in the fourth direction h14 is S5, where S111≤S5≤S112. This allows for a reduced distance between the support portion 5 and the first five sub-pixels 211 while preventing mutual interference between the first sub-partition portion 311 and the support portion 5. For example, the area of ​​the first five sub-pixels 211 can be set as large as possible to increase the aperture ratio of the first five sub-pixels 211, avoid driving the display of the first five sub-pixels 211 with excessive current density, extend the life of the first five sub-pixels 211, and improve the display quality of the display panel 100.

[0134] For example, combined Figure 7 and Figure 14 As shown, Figure 14This is an enlarged schematic diagram of another embodiment of the present invention, showing a first sub-pixel 211, a first partition portion, and a support portion. The first sub-pixel 211 further includes a plurality of first nail edges E11, with two adjacent first nail edges E11 forming a vertex angle A of the first sub-pixel 211. The first sub-partition portion 311 further includes a first notch 41 corresponding to the first nail edge E11. The correspondence between the first notch 41 and the first nail edge E11 means that the line connecting the center of the first notch 41 and the center of gravity of the virtual circumscribed quadrilateral of the first sub-pixel 211 passes through the first nail edge E11.

[0135] On the basis of setting the first notch 41 corresponding to the top angle A mentioned above, the first notch 41 set corresponding to the first nail edge E11 can further increase the number of first notches 41 in the first sub-partition portion 311, thereby improving the reliability of the second electrode set at the corresponding first nail edge E11, increasing the reliable transmission path of the signal transmitted by the second electrode, reducing the signal voltage drop, and helping to improve display uniformity. Figure 14 For example, two first notches 41 corresponding to the first nail edge E11 and one first notch 41 corresponding to the vertex A are provided in the first sub-partition portion 311 .

[0136] In the embodiment of the present utility model, Figure 14 As shown, the distance between the two endpoints of the first notch 41 corresponding to the first nail edge E11 is S113, and the distance between the two endpoints of the first notch 41 corresponding to the vertex A of the first sub-pixel 211 and close to the support portion 5 is S112, where S113 ≤ S112. Based on this arrangement, by increasing the distance between the two endpoints of the first notch 41 close to the support portion 5, the distance between the support portion 5 and the first sub-partition portion 311 can be increased, thereby further reducing the difficulty of setting up the support portion 5. In addition, by minimizing the distance between the two endpoints of the first notch 41 corresponding to the first nail edge E11, the embodiment of the present invention can reduce the area of ​​the region where lateral leakage current occurs around the first sub-pixel 211, thereby further improving the reliability of the display panel.

[0137] For example, Figure 14 As shown, the length of the support portion 5 in the fourth direction h14 is S5, where S113 ≤ S5 ≤ S112. Based on this arrangement, while preventing mutual interference between the first sub-partition portion 311 and the support portion 5, the distance between the support portion 5 and the first five sub-pixels 211 can be shortened. For example, the area of ​​the first five sub-pixels 211 can be set as large as possible to increase the aperture ratio of the first five sub-pixels 211, avoid driving the display of the first five sub-pixels 211 with excessive current density, extend the life of the first five sub-pixels 211, and improve the display quality of the display panel 100.

[0138] For example, Figure 1 、 Figure 7 、 Figure 8 、 Figure 9 、 Figure 10 and Figure 11 As shown, the first sub-pixel 21 includes a first B sub-pixel 212, and no support portion 5 is provided between the first B sub-pixel 212 and the adjacent second sub-pixel 22. For example, no support portion 5 is provided between the first B sub-pixel 212 and the adjacent second sub-pixel 22 in the third direction h13; and no support portion 5 is provided between the first B sub-pixel 212 and the adjacent second sub-pixel 22 in the fourth direction h14.

[0139] For example, Figure 1 、 Figure 8 、 Figure 9 and Figure 10 As shown, the first B sub-pixel 212 includes a vertex A. The first partition portion 31 includes a second sub-partition portion 312. The second sub-partition portion 312 at least partially surrounds the first B sub-pixel 212. The second sub-partition portion 312 includes a first notch 41 corresponding to the vertex A of the first B sub-pixel 212. The first notch 41 ensures good connection of the second electrode located outside the vertex A of the first B sub-pixel 212.

[0140] Exemplarily, in an embodiment of the present invention, the first B sub-pixel 212 includes at least two vertex angles A, and the second sub-partition portion 312 includes at least two first notches 41, and the two first notches 41 correspond to different vertex angles A respectively; along the third direction h13 or the fourth direction h14, the two first notches 41 are located on both sides of the first B sub-pixel 212. Figure 1 and Figure 9 As an example, two first notches 41 are arranged along the third direction h13 on both sides of the first B sub-pixel 212 . Figure 10 As an example, two second openings 41 are arranged along the fourth direction h14 on both sides of the first B sub-pixel 212 .

[0141] In another optional embodiment, as Figure 8 As shown, the first sub-partitioning portion 311 includes only one first notch 41, corresponding to the vertex A of the first sub-pixel 211 and located near the support portion 5. This arrangement reduces the number of first notches 41 provided around the periphery of the first sub-pixel 211, further alleviating the problem of hidden brightness in the first sub-pixel 211. For example, in this case, embodiments of the present invention may also include only one first notch 41 in the second sub-partitioning portion 312, corresponding to the vertex A of the first sub-pixel 212.

[0142] Optionally, the embodiment of the present invention can make the number and position distribution pattern of the first notches 41 around the first A sub-pixel 211 and the first B sub-pixel 212 as consistent as possible, so that the degree of lateral leakage current around the first A sub-pixel 211 and the first B sub-pixel 212 can be consistent, and the morphology of the second electrode of the first A sub-pixel 211 and the second electrode of the first B sub-pixel 212 can be consistent, so as to improve the display consistency of the first A sub-pixel 211 and the first B sub-pixel 212, and improve the display uniformity of the display panel.

[0143] When providing the first notch 41 corresponding to the vertex angle A of the first B sub-pixel 212, the distance between the two endpoints of the first notch 41 corresponding to the vertex angle A of the first B sub-pixel 212 is S121, and the distance between the two endpoints of the first notch 41 corresponding to the vertex angle A of the first A sub-pixel 211 and close to the support portion 5 is S112. In this embodiment of the utility model, S121 ≤ S112. Since the support portion 5 is not provided around the periphery of the first B sub-pixel 212, the area left in this region for the first partition portion 31 is relatively large. This distance between the two endpoints of the first notch 41 corresponding to the vertex angle A of the first B sub-pixel 212 can be appropriately reduced. This reduces the area of ​​the region around the first B sub-pixel 212 where lateral leakage current occurs, while not affecting the provision of the support portion 5. This further improves the display quality of the display panel.

[0144] For example, Figure 7 As shown, the first B sub-pixel 212 further includes a plurality of first B edges E12 , two adjacent first B edges E12 form a vertex A of the first B sub-pixel 212 , and the second sub-partitioning portion 312 further includes a first notch 41 corresponding to the first B edge E12 .

[0145] Combine Figure 7 and Figure 15 As shown, Figure 15 This is an enlarged schematic diagram of a first B sub-pixel and a first partition provided by an embodiment of the present invention. The distance between the two end points of the first notch 41 corresponding to the first B edge E12 is S122. Figure 14 As shown, the distance between the two endpoints of the first notch 41 corresponding to the vertex A of the first A sub-pixel 211 and close to the support portion 5 is S112. In this embodiment of the present invention, S122 ≤ S112. No support portion 5 is provided around the periphery of the first B sub-pixel 212. Therefore, by minimizing the distance between the two endpoints of the first notch 41 corresponding to the first B edge E12, this embodiment of the present invention can reduce the area of ​​the region around the first B sub-pixel 212 where lateral leakage current occurs, while not affecting the arrangement of the support portion 5, thereby further improving the display quality of the display panel.

[0146] For example, continue to refer to Figure 9 and Figure 10 As shown, the first sub-pixel 21 includes the first A sub-pixel 211 and the first B sub-pixel 212. Along the third direction h13 or the fourth direction h14, the support portion 5 is located between the first A sub-pixel 211 and the second sub-pixel 22, and the first B sub-pixel 212 and the second sub-pixel 22 do not include the support portion 5. Figure 9 and Figure 10 As an illustration, it is assumed that the support portion 5 is located between the first sub-pixel 211 and the second sub-pixel 22 along the third direction h13 .

[0147] like Figure 9 and Figure 10 As shown, the first partition portion 31 includes a first A partition portion 313 and a first B partition portion 314. The first A partition portion 313 at least partially surrounds the first A sub-pixel 211, and the first B partition portion 314 at least partially surrounds the first B sub-pixel 212. Exemplarily, the first A partition portion 313 includes the first sub-partition portion 311, and the first B partition portion 314 includes the second sub-partition portion 312.

[0148] In the embodiment of the present utility model, the shape of the first A partition portion 313 is the same as the shape of the first B partition portion 314; the shape of the first notch 41 in the first A partition portion 313 is the same as the shape of the first notch 41 in the first B partition portion 314. The length of the first A partition portion 313 is the same as the length of the first B partition portion 314; the width of the first A partition portion 313 is the same as the width of the first B partition portion 314; wherein, the length directions of the first A partition portion 313 and the first B partition portion 314 are parallel to their respective extension directions, and the width directions are perpendicular to their respective extension directions. The distance between the two end points of the first notch 41 in the first A partition portion 313 is the same as the distance between the two end points of the first notch 41 in the first B partition portion 314. Figure 9 and Figure 10 As shown, the first A sub-pixel 211 can be translated to overlap with the first B sub-pixel 212. The first A partition portion 313 can be translated to overlap with the first B partition portion 314. The first notch 41 in the first A partition portion 313 can be translated to overlap with the first notch 41 in the first B partition portion 314.

[0149] Based on this arrangement, the distribution patterns of the first partition portion 31 and the first notch 41 around the first A sub-pixel 211 and the first B sub-pixel 212, which have different positional relationships with the support portion 5, can be made the same, thereby making the degree of lateral leakage current around the first A sub-pixel 211 and the first B sub-pixel 212 tend to be consistent, and the morphology of the second electrode of the first A sub-pixel 211 and the second electrode of the first B sub-pixel 212 tend to be consistent, which is beneficial to improving the display uniformity of the display panel.

[0150] Optional, such as Figure 9 As shown, the first notch 41 in the first A partition portion 313 is set corresponding to the vertex A of the first A sub-pixel 211; the first notch 41 in the first B partition portion 314 is set corresponding to the vertex A of the first B sub-pixel 212; along the third direction h13, two first notches 41 are located on both sides of the first A sub-pixel 211, and two first notches 41 are located on both sides of the first B sub-pixel 212.

[0151] Or, as Figure 10 As shown, along the fourth direction h14 , two first notches 41 are located on both sides of the first A sub-pixel 211 , and two first notches 41 are located on both sides of the first B sub-pixel 212 .

[0152] Optional, based on Figure 10 In the arrangement shown, the widths of the first A partition portion 313 and the first B partition portion 314 can be appropriately compressed to prevent the first A partition portion 313 from interfering with the support portion 5. For example, the width W of the first A partition portion 313 and the first B partition portion 314 can satisfy 1.5 μm ≤ W ≤ 3.5 μm.

[0153] The above description is based on the case where the shape of the first sub-pixel 21 is designed to be a quadrilateral. In other embodiments, the present invention can also configure the first sub-pixel 21 to include the above-mentioned convex portion and the main body. Figure 16 and Figure 17 As shown, Figure 16 A schematic diagram of another display panel provided by an embodiment of the present utility model is shown. Figure 17 for Figure 16 An enlarged schematic diagram of the first type of sub-pixel, the second type of sub-pixel, the third type of sub-pixel and the fourth type of sub-pixel, wherein the first sub-pixel 21 includes a protrusion 201 and a main body 202; the protrusion 201 includes a first edge E1 away from the main body 202, and the first edge E1 includes an arc segment C.

[0154] In the embodiment of the present invention, the first sub-pixel 21 includes a virtual circumscribed quadrilateral. Figure 17As shown, the first sub-pixel 21 includes a first type of sub-pixel 213, a second type of sub-pixel 214, a third type of sub-pixel 215 and a fourth type of sub-pixel 216; wherein, the direction in which the center of gravity Q1 of the orthographic projection of the virtual circumscribed quadrilateral of the first type of sub-pixel 213 on the plane where the substrate 1 is located points to the center Q2 of the first edge E1 is parallel to the first direction h11; the direction in which the center of gravity Q1 of the orthographic projection of the virtual circumscribed quadrilateral of the second type of sub-pixel 214 on the plane where the substrate 1 is located points to the center Q2 of the first edge E1 is parallel to the second direction h12; the direction in which the center of gravity Q1 of the orthographic projection of the virtual circumscribed quadrilateral of the third type of sub-pixel 215 on the plane where the substrate 1 is located points to the center Q2 of the first edge E1 is parallel to the opposite direction of the first direction h11; the direction in which the center of gravity Q1 of the orthographic projection of the virtual circumscribed quadrilateral of the fourth type of sub-pixel 216 on the plane where the substrate 1 is located points to the center Q2 of the first edge E1 is parallel to the opposite direction of the second direction h12; wherein, the center of the first edge E1 refers to the midpoint of the line connecting the two end points of the first edge E1.

[0155] When the first type of sub-pixel 213, the second type of sub-pixel 214, the third type of sub-pixel 215 and the fourth type of sub-pixel 216 are arranged, for example, Figure 16 As shown, in any row of sub-pixels, such as in the mth row of sub-pixels 11_m, the embodiment of the present invention can arrange the first type of sub-pixels 213, the fourth type of sub-pixels 216, the second type of sub-pixels 214 and the third type of sub-pixels 215 alternately in sequence along the first direction h11.

[0156] For example, Figure 16 As shown, for the mth row of sub-pixels 11_m and the m+2th row of sub-pixels 11_m+2, the fourth-category sub-pixels 216 in one row of sub-pixels can be aligned with the second-category sub-pixels 214 in another row of sub-pixels in the second direction h12. The first-category sub-pixels 213 in one row of sub-pixels can be aligned with the third-category sub-pixels 215 in another row of sub-pixels in the second direction h12. That is, in any column of sub-pixels, such as the nth column of sub-pixels 11_n, the embodiment of the present invention can arrange the second-category sub-pixels 214, the fourth-category sub-pixels 216, the first-category sub-pixels 213, and the third-category sub-pixels 215 alternately along the second direction h12. Both m and n are positive integers. Based on this arrangement, the first sub-pixels 21 with protrusions 201 in different orientations can be evenly distributed in the display panel, which is beneficial to improving display uniformity.

[0157] For example, Figure 1 、 Figure 7 、 Figure 8 、 Figure 9 、 Figure 10 、 Figure 11 and Figure 16As shown, the second sub-pixel 22 includes a second sub-pixel 221, and the support portion 5 is located between the second sub-pixel 221 and the first sub-pixel 21. The second sub-pixel 221 includes a vertex angle A. The vertex angle A of the second sub-pixel 221 is formed by two adjacent sides of the second sub-pixel 22. In the embodiment of the present invention, either of the two adjacent sides of the second sub-pixel 22 can be a straight line segment or an arc segment. Figure 1 、 Figure 7 、 Figure 8 、 Figure 9 、 Figure 10 、 Figure 11 and Figure 16 The second sub-pixel 22 is shown as having one arc segment and three straight line segments. The second partitioning portion 32 includes a third sub-partitioning portion 321 , which at least partially surrounds the second sub-pixel 221 .

[0158] Optional, such as Figure 18 As shown, Figure 18 This is an enlarged schematic diagram of a second sub-pixel, a third sub-partition portion, and a support portion provided by an embodiment of the present invention. The third sub-partition portion 321 includes a second notch 42 corresponding to the top angle A of the second sub-pixel 221 .

[0159] Optional, such as Figure 1 、 Figure 7 、 Figure 8 and Figure 10 As shown, along the third direction h13 , at least a portion of the support portion 5 is located between the second x sub-pixel 221 and the first x sub-pixel 211 .

[0160] Or, as Figure 7 As shown, along the fourth direction h14 , another portion of the support portion 5 is located between the second x sub-pixel 221 and the first x sub-pixel 211 .

[0161] In the embodiment of the present invention, by arranging the second notch 42 to correspond to the top corner A of the second sub-pixel 221 , the second electrode 202 can have a greater thickness at the top corner A of the second sub-pixel 221 , thereby ensuring a reliable connection between the second electrode 202 of the second sub-pixel 221 and the top corner A of the second sub-pixel 221 .

[0162] For example, Figure 1 、 Figure 7 、 Figure 8 and Figure 10As shown, the second notch 42 corresponding to one of the vertex corners A of the second sub-pixel 221 is located on the side of the second sub-pixel 221 closest to the support portion 5. Because the second sub-pixel 221 is located close to the support portion 5, the present embodiment of the utility model positions the second notch 42 corresponding to the vertex corner A of the second sub-pixel 221 on the side of the second sub-pixel 221 closest to the support portion 5. That is, no raised or recessed portion is provided around the vertex corner A of the second sub-pixel 221 on the side closest to the support portion 5. This prevents raised or recessed portions from occupying space on the support portion 5, thereby reducing the difficulty of installing the support portion 5. Furthermore, this arrangement eliminates the need to excessively compress the area of ​​the support portion 5, ensuring the support effectiveness of the support portion 5.

[0163] For example, continue to refer to Figure 7 and Figure 10 As shown, the second sub-pixel 221 includes at least two vertex angles A, and the third sub-partitioning portion 321 includes at least two second notches 42, each corresponding to a different vertex angle A. One second notch 42 is located on the side of the second sub-pixel 221 closest to the support portion 5, while the other second notch 42 is located on the side of the second sub-pixel 221 further away from the support portion 5. The second notch 42 positioned closer to the support portion 5 avoids the need for protrusions or depressions around the vertex angles A on the side of the second sub-pixel 221 closest to the support portion 5, thus preventing the protrusions or depressions from occupying space on the support portion 5 and thus reducing the difficulty of installing the support portion 5. Furthermore, the placement of the second notches 42 further away from the support portion 5 increases the number of second notches 42, thereby increasing the number of reliable connection locations for the second electrode and, consequently, increasing the conductive paths for the signal transmitted by the second electrode. For example, at least in the direction in which the two second notches 42 are arranged, the signal transmitted by the second electrode can be smoothly transmitted.

[0164] In the embodiment of the present utility model, continue to refer to Figure 7 As shown, the distance between the two end points of the second notch 42 away from the support portion 5 is S211, and the distance between the two end points of the second notch 42 close to the support portion 5 is S212, where S211 ≤ S212. Based on this arrangement, by increasing the distance between the two end points of the second notch 42 close to the support portion 5, the distance between the support portion 5 and the non-notch portion of the third sub-partition portion 313 can be increased, thereby further reducing the difficulty of setting up the support portion 5.

[0165] For example, the length of the support portion 5 in the fourth direction h14 is S5, where S211 ≤ S5 ≤ S112. This reduces the distance between the support portion 5 and the second sub-pixel 221 while preventing interference between the third sub-partition portion 321 and the support portion 5. For example, the area of ​​the second sub-pixel 221 can be maximized to extend its lifespan and improve the display quality of the display panel 100.

[0166] For example, combined Figure 1 、 Figure 8 and Figure 18 As shown, the second A sub-pixel 221 further includes a plurality of second A edges E21, and two adjacent second A edges E21 form a vertex angle A of the second A sub-pixel 221. Figure 1 、 Figure 8 and Figure 18 As an example, four second A edges E21 are provided in the second A sub-pixel 221 , three of which include straight line segments and one includes an arc segment.

[0167] like Figure 1 、 Figure 8 and Figure 18 As shown, the third sub-partition portion 321 also includes a second notch 42 corresponding to the second nail edge E21. The distance between the two end points of the second notch 42 corresponding to the second nail edge E21 is S213, and the distance between the two end points of the second notch 42 corresponding to the vertex A of the second sub-pixel 221 and close to the support portion 5 is S212; where S213 ≤ S212. Based on this arrangement, by increasing the distance between the two end points of the second notch 42 close to the support portion 5, the distance between the support portion 5 and the third sub-partition portion 321 can be increased, thereby further reducing the difficulty of setting up the support portion 5. In addition, by minimizing the distance between the two end points of the second notch 42 corresponding to the second nail edge E21, the area of ​​the region where lateral leakage current occurs around the second sub-pixel 221 can be reduced, thereby further improving the reliability of the display panel.

[0168] For example, Figure 18 As shown, the length of the support portion 5 in the fourth direction h14 is S5, where S213 ≤ S5 ≤ S212. This prevents interference between the third sub-partition portion 321 and the support portion 5 while reducing the distance between the support portion 5 and the second sub-pixel 221. For example, the area of ​​the second sub-pixel 221 can be set as large as possible to extend the life of the second sub-pixel 221 and improve the display quality of the display panel 100.

[0169] For example, combined Figure 16 and Figure 19 As shown, Figure 19 for Figure 16 An enlarged schematic diagram of a second sub-pixel, a third sub-partition portion, and a support portion, wherein the second sub-pixel 221 includes a protruding portion 201 and a main portion 202; at least a portion of the arc segment C is located on a side of the second sub-pixel 221 close to the support portion 5; Figure 19 As an example, the arc segment C is positioned on the side of the second quadrilateral pixel 221 close to the support portion 5. Positioning the arc segment C on the side of the second quadrilateral pixel 221 close to the support portion 5 means that the line connecting the center of gravity of the virtual circumscribed quadrilateral of the second quadrilateral pixel 221 and the center of gravity of the support portion 5 passes through the arc segment C. In this embodiment of the present invention, the second partition portion 32 includes a second edge E2, which is located between at least a portion of the arc segment C and the support portion 5.

[0170] Based on this setting method, on the one hand, the formation of a second gap at the second edge E2 can be avoided, so that the part of the second partition portion 32 located at the second edge E2 can be used to suppress the leakage current from the peripheral sub-pixels from affecting the second A sub-pixel 221, avoiding the formation of a leakage channel at this position, thereby improving the consistency of the leakage current transmission path in this area and other areas where the support portion 5 is not set, for example, improving the consistency of the leakage current transmission path around the second A sub-pixel 221 and the second B sub-pixel 222, which is beneficial to improving the display uniformity of the display panel.

[0171] On the other hand, by providing the second edge E2 at this position of the second partition portion 32 instead of providing a corner structure protruding toward the support portion 5, it is possible to avoid reducing the distance between the second partition portion 32 and the support portion 5. This not only reduces the difficulty of setting up the second partition portion 32 and the support portion 5, but also eliminates the need to reduce the area of ​​the support portion 5, thereby ensuring the supporting effect of the support portion 5.

[0172] In another optional embodiment, as Figure 20 As shown, Figure 20 This is a schematic diagram of another display panel provided by an embodiment of the present invention. When the second edge E2 is provided in the second partition portion 32 , the first sub-pixel 21 may also be provided as a quadrilateral in the embodiment of the present invention. Figure 20 and Figure 16 The only difference is the shape of the first sub-pixel 21, and other configurations can be the same.

[0173] When setting the second sub-pixel 221, illustratively, Figure 21 and Figure 22 As shown, Figure 21 A schematic diagram of another display panel provided by an embodiment of the present utility model is shown. Figure 22 for Figure 21In an enlarged schematic diagram of a second sub-pixel, a third sub-partition portion, and a support portion, the present embodiment of the utility model can configure the main portion 202 to include a first straight line segment L1 and a second straight line segment L2, wherein the first straight line segment L1 and the second straight line segment L2 intersect; one end of an arc segment C is connected to the first straight line segment L1, and the other end of the arc segment C is connected to the second straight line segment L2; the first straight line segment L1 and the second straight line segment L2 intersect at a first vertex B. In other words, the shape of the second sub-pixel 221 is designed to be approximately teardrop-shaped.

[0174] Optional, such as Figure 21 As shown, the third sub-partition portion 321 includes a second edge E2 , and the second edge E2 is located between at least a portion of the arc segment C and the support portion 5 .

[0175] It should be noted that Figure 21 The shape of the second sub-pixel 22 is designed to be approximately teardrop-shaped, and the shape of the first sub-pixel 21 is designed to be a quadrilateral for illustration only. When the first sub-pixel 21 is designed to have a structure including a protruding portion and a main body, the embodiment of the present invention can also design the shape of the first sub-pixel 21 to be approximately teardrop-shaped, which is not illustrated in the figure.

[0176] like Figure 23 and Figure 24 As shown, Figure 23 A schematic diagram of another display panel provided by an embodiment of the present utility model is shown. Figure 24 for Figure 23 An enlarged schematic diagram of a second sub-pixel, a third sub-partitioning portion and a supporting portion, wherein the shape of the second sub-pixel 221 and Figure 21 The same as Figure 21 The difference is that in Figure 23 and Figure 24 In addition to the second edge E2, the second partition portion 32 further includes a third edge E3. The third edge E3 is located on a side of the second sub-pixel 221 away from the second edge E2.

[0177] Based on this setting method, on the one hand, the formation of a second gap at the third edge E3 can be avoided, so that the part of the second partition portion 32 located at the third edge E3 can be used to suppress the leakage current from the peripheral sub-pixels from affecting the second A sub-pixel 221, avoiding the formation of a leakage channel at this position, thereby improving the consistency of the leakage current transmission path in this area and other areas where the support portion 5 is not set, for example, improving the consistency of the leakage current transmission path around the second A sub-pixel 221 and the second B sub-pixel 222, which is beneficial to improving the display uniformity of the display panel.

[0178] On the other hand, by setting the third edge E3 at this position instead of setting a corner structure protruding toward the side away from the second sub-pixel 221 in the third direction h13, the area of ​​the region defined by the outline of the second partition portion 32 can be reduced, thereby leaving space for the setting of the sub-pixel.

[0179] For example, Figure 23 and Figure 24 As shown, in this embodiment of the present invention, a fourth edge E4 may be further provided in the second partition portion 32, and the fourth edge E4 is located on the side of the second sub-pixel 22 away from the first vertex B. Based on this arrangement, the second partition portion 32 can be prevented from being provided at the arc segment C of the second sub-pixel 22 with an angled structure that protrudes in the fourth direction h14 toward the side away from the second A sub-pixel 221, thereby further reducing the area defined by the outline of the second partition portion 32.

[0180] For example, continue to refer to Figure 19 As shown, the second sub-pixel 221 further includes a plurality of second nail edges E21, two adjacent second nail edges E21 form a vertex angle A of the second sub-pixel 221, and the third sub-partitioning portion 321 further includes a second notch 42 corresponding to the second nail edge E21; wherein the second nail edge E21 can be a straight line segment or an arc segment. Figure 19 As an example, the second A sub-pixel 221 includes four second A edges E21, three of which include straight line segments and one includes an arc segment. The third sub-partitioning portion 321 includes three second notches 42 corresponding to three of the straight line segments and one second notch 42 corresponding to one arc segment.

[0181] like Figure 19 As shown, the distance between the two endpoints of the second notch 42 corresponding to the second nail edge E21 is S213, and the length of the second edge E2 is S22, where S213 ≤ S22. Based on this arrangement, by increasing the length of the second edge E2 near the support portion 5, the distance between the support portion 5 and the third sub-partition portion 321 can be increased, further reducing the difficulty of installing the support portion 5. In addition, by minimizing the distance between the two endpoints of the second notch 42 corresponding to the second nail edge E21, the area where lateral leakage current occurs can be reduced, thereby further improving the reliability of the display panel.

[0182] For example, Figure 19As shown, the length of the support portion 5 in the fourth direction h14 is S5, where S213 ≤ S5 ≤ S22. This prevents interference between the third sub-partition portion 321 and the support portion 5 while reducing the distance between the support portion 5 and the second sub-pixel 221. For example, the area of ​​the second sub-pixel 221 can be set as large as possible to extend the life of the second sub-pixel 221 and improve the display quality of the display panel 100.

[0183] For example, continue to refer to Figure 16 As shown, the second sub-pixel 22 includes a protruding portion 201 and a main portion 202; the protruding portion 201 includes a fifth edge E5 away from the main portion 202; the second sub-pixel 22 includes a virtual circumscribed quadrilateral; the second sub-pixel 22 includes a fifth type of sub-pixel 223, a sixth type of sub-pixel 224, a seventh type of sub-pixel 225, and an eighth type of sub-pixel 226; wherein the center of gravity of the orthographic projection of the virtual circumscribed quadrilateral of the fifth type of sub-pixel 223 on the plane where the substrate is located points to the center of the fifth edge E5 in a direction parallel to the first direction h11; the virtual circumscribed quadrilateral of the sixth type of sub-pixel 224 The direction in which the center of gravity of the orthographic projection on the plane where the substrate is located points to the center of the fifth edge E5 is parallel to the second direction h12; the direction in which the center of gravity of the orthographic projection of the virtual circumscribed quadrilateral of the seventh type of sub-pixel 225 on the plane where the substrate is located points to the center of the fifth edge E5 is parallel to the opposite direction of the first direction h11; the direction in which the center of gravity of the orthographic projection of the virtual circumscribed quadrilateral of the eighth type of sub-pixel 226 on the plane where the substrate 1 is located points to the center of the fifth edge E5 is parallel to the opposite direction of the second direction h12; wherein, the center of the fifth edge E5 refers to the midpoint of the line connecting the two end points of the fifth edge E5.

[0184] When arranging the fifth type of sub-pixel 223, the sixth type of sub-pixel 224, the seventh type of sub-pixel 225, and the eighth type of sub-pixel 226, for example, Figure 16 As shown, in any row of sub-pixels, such as the m+1th row of sub-pixels 11_m+1, embodiments of the present invention can arrange the fifth, seventh, sixth, and eighth sub-pixels 223, 225, 224, and 226 of the sub-pixel category alternately along the first direction h11. In any column of sub-pixels, such as the n+1th column of sub-pixels 11_n+1, embodiments of the present invention can arrange the fifth, eighth, sixth, and seventh sub-pixels 223, 226, 224, and 225 of the sub-pixel category alternately along the second direction h12. This arrangement allows the second sub-pixels 22 with protrusions 201 in different orientations to be evenly distributed across the display panel, facilitating improved display uniformity.

[0185] When setting the second sub-pixel 22, illustratively, as Figure 25 and Figure 12C As shown, Figure 25 A schematic diagram of another display panel provided by an embodiment of the present utility model is shown. Figure 12C Can be seen as Figure 25 : An enlarged schematic diagram of a second sub-pixel in FIG. The second sub-pixel 22 includes a protruding portion 201 and a main portion 202. The arc segment C includes a first arc segment C1 and a second arc segment C2. The edge of the protruding portion 201 away from the main portion 202 also includes a straight line segment L connecting the first arc segment C1 and the second arc segment C2. The length of the first arc segment C1 is greater than the length of the second arc segment C2. The two endpoints of the first arc segment C1 are P1 and P2, the two endpoints of the second arc segment C2 are P3 and P4, and the two endpoints of the straight line segment L are P2 and P3. For example, Figure 12C As shown, the distance between P1 and P2 in the first direction h11 is d1, and the distance between P3 and P4 in the first direction h11 is d2, where d1≠d2. Based on this configuration, the flexibility of the shape design of the second sub-pixel 22 can be improved.

[0186] like Figure 1 、 Figure 7 、 Figure 8 、 Figure 9 、 Figure 10 、 Figure 11 、 Figure 16 、 Figure 21 and Figure 23 As shown, the second sub-pixel 22 further includes a second B sub-pixel 222. No support portion 5 is provided between the second B sub-pixel 222 and the adjacent first sub-pixel 21. In this embodiment of the present invention, no support portion 5 is provided between the second B sub-pixel 222 and the adjacent first sub-pixel 21 in the third direction h13. Furthermore, no support portion 5 is provided between the second B sub-pixel 222 and the adjacent first sub-pixel 21 in the fourth direction h14.

[0187] For example, Figure 7 and Figure 10 As shown, the second B sub-pixel 222 includes a vertex A. The second partitioning portion 32 includes a fourth sub-partitioning portion 322. The fourth sub-partitioning portion 322 at least partially surrounds the second B sub-pixel 222. The fourth sub-partitioning portion 322 includes a second notch 42 corresponding to the vertex A of the second B sub-pixel 222. The provision of the second notch 42 ensures a good connection of the second electrode located outside the vertex A of the second B sub-pixel 222.

[0188] For example, Figure 1 、 Figure 8 、 Figure 9 、 Figure 11 、 Figure 16 、 Figure 21 and Figure 23As shown, the second B sub-pixel 222 further includes a plurality of second B edges E22, two adjacent second B edges E22 forming a vertex angle A of the second B sub-pixel 222, and the fourth sub-partitioning portion 322 further includes a second notch 42 corresponding to the second B edge E22; the distance between the two end points of the second notch 42 corresponding to the second B edge E22 is S222, combined with Figure 18 As shown, the distance between the two endpoints of the second notch 42, corresponding to the vertex A of the second A sub-pixel 221 and close to the support portion 5, is S212. In this embodiment of the present invention, S222 ≤ S212. By increasing the distance between the two endpoints of the second notch 42 close to the support portion 5, this embodiment of the present invention can increase the distance between the support portion 5 and the third sub-partitioning portion 321, thereby further reducing the difficulty of installing the support portion 5. In addition, by minimizing the distance between the two endpoints of the second notch 42, corresponding to the second B edge E22, the area of ​​the region where lateral leakage current occurs around the second B sub-pixel 222 can be reduced, thereby further improving the display quality of the display panel.

[0189] Optionally, in the embodiment of the present utility model, S222 may be set to S213.

[0190] For example, the embodiment of the present invention can make S212=2×S213=2×S222. Based on this setting, combined with Figure 1 and Figure 8 As shown, when the third sub-partition portion 321 is set to include two second notches 42 respectively corresponding to different second A edges E21 and one second notch 42 corresponding to the top corner A of the second A sub-pixel 221, and when the fourth sub-partition portion 322 is set to include four second notches 42 respectively corresponding to different second B edges E22, the second notches 42 around the second A sub-pixel 221 can occupy the same area ratio of the second partition portion 32 as the second notches 42 around the second B sub-pixel 222 occupy the same area ratio of the second partition portion 32, thereby making the brightness levels of the second A sub-pixel 221 and the second B sub-pixel 222 tend to be consistent, thereby improving the display consistency of the display panel in different areas.

[0191] For example, continue to refer to Figure 9 and Figure 10 As shown, the second sub-pixel 22 includes the above-mentioned second A sub-pixel 221 and the above-mentioned second B sub-pixel 222, and the second partition portion 32 includes the second A partition portion 323 and the second B partition portion 324. The second A partition portion 323 at least partially surrounds the second A sub-pixel 221, and the second B partition portion 324 at least partially surrounds the second B sub-pixel 222; illustratively, the second A partition portion 323 includes the above-mentioned third sub-partition portion 321, and the second B partition portion 324 includes the above-mentioned fourth sub-partition portion 322.

[0192] In this embodiment of the present invention, the shape of the second A partition portion 323 is identical to the shape of the second B partition portion 324; the length of the second A partition portion 323 is identical to the length of the second B partition portion 324; the width of the second A partition portion 323 is identical to the width of the second B partition portion 324; wherein the length direction of the second A partition portion 323 and the second B partition portion 324 are parallel to their respective extension directions, and the width direction is perpendicular to their respective extension directions. The distance between the two end points of the second notch 42 in the second A partition portion 323 is identical to the distance between the two end points of the second notch 42 in the second B partition portion 324.

[0193] like Figure 9 and Figure 10 As shown, the second A sub-pixel 221 can be translated to overlap with the second B sub-pixel 222. The second A partition portion 323 can be translated to overlap with the second B partition portion 324. The second notch 42 in the second A partition portion 323 can be translated to overlap with the second notch 42 in the second B partition portion 324.

[0194] Based on this arrangement, the distribution patterns of the second partition portion 32 and the second notch 42 around the second-A sub-pixel 221 and the second-B sub-pixel 222, which have different positional relationships with the support portion 5, can be made the same, thereby making the degree of lateral leakage current around the second-A sub-pixel 221 and the second-B sub-pixel 222 tend to be consistent, and the morphologies of the second electrode of the second-A sub-pixel 221 and the second electrode around the second-B sub-pixel 222 tend to be consistent, which is beneficial to improving the display uniformity of the display panel.

[0195] For example, Figure 10 As shown, in the embodiment of the present invention, the second notch 42 in the second A partition portion 323 can be set to correspond to the vertex A of the second A sub-pixel 221 , and the second notch 42 in the second B partition portion 324 can be set to correspond to the vertex A of the second B sub-pixel 222 .

[0196] Or, as Figure 9 As shown, in the embodiment of the present invention, the second notch 42 in the second A partition portion 323 may be arranged to correspond to the edge of the second A sub-pixel 221 ; and the second notch 42 in the second B partition portion 324 may be arranged to correspond to the edge of the second B sub-pixel 222 .

[0197] Optional, based on Figure 9 In this arrangement, the widths of the second A partition portion 323 and the second B partition portion 324 can be appropriately compressed to avoid mutual interference between the second A partition portion 323 and the support portion 5. Optionally, the width W of the second A partition portion 323 and the second B partition portion 324 can satisfy 1.5 μm ≤ W ≤ 3.5 μm.

[0198] For example, Figure 7 As shown, no partition is provided around the third sub-pixel 23. Based on this arrangement, the second electrode ( Figure 7 The signal transmitted by the second electrode (not shown) is input from the frame area on both sides of the display panel in the third direction h13 and is transmitted along the third direction h13 to form a current transmission channel, which is beneficial to reducing the voltage drop of the signal transmitted by the second electrode during the transmission process and improving the display effect. Figure 7 A straight line with an arrow indicates one of the transmission paths of the above signal.

[0199] Moreover, if Figure 7 As shown, in the display panel, the number of the third sub-pixels 23 per unit area is greater than the number of the first sub-pixels 21 and the second sub-pixels 22. In the embodiment of the present invention, no partition is provided around the third sub-pixel 23, and the number of the third sub-pixels 23 can be adjusted according to the embodiment of the present invention. Figure 7 The method shown sets the first partition part 31 and the second partition part 32 on the periphery of the first sub-pixel 21 and the second sub-pixel 22 respectively. On the one hand, it has a better improvement effect on the problem of the first sub-pixel 21 being too bright. For example, when the first sub-pixel 21 is set as a red sub-pixel, the second sub-pixel 22 is set as a blue sub-pixel, and the third sub-pixel 23 is set as a green sub-pixel, when the display panel displays a blue picture, in the related art, under different brightness levels, due to the problem of the red sub-pixel being too bright, the color coordinates of the blue picture will change greatly, resulting in a reddish visual effect. Figure 7 The provided arrangement effectively suppresses the phenomenon of red sub-pixels secretly lighting up under a blue screen. Furthermore, it reduces the area occupied by the partition 3, increasing the conductive path for the signal transmitted by the second electrode, further facilitating the reduction of voltage drop during signal transmission, lowering the power consumption of the display panel, and improving the display uniformity of the display panel.

[0200] For example, Figure 1 、 Figure 8 、 Figure 9 、 Figure 10 、 Figure 11 、 Figure 16 、 Figure 21 、 Figure 23 、 Figure 25 、 Figure 26 and Figure 27 As shown, Figure 26 and Figure 27Schematic diagrams of two other display panels provided by embodiments of the present invention. The partition portion 3 further includes a third partition portion 33, which at least partially surrounds the third sub-pixel 23 and includes at least one third notch 43. The provision of the third partition portion 33 can extend or block the lateral leakage current transmission path between the third sub-pixel 23 and adjacent sub-pixels of different colors, such as the first sub-pixel 21 or the second sub-pixel 22, thereby improving the display quality of the display panel. The provision of the third notch 43 can also enhance the connection reliability of the second electrode at this location, thereby improving the display uniformity of the display panel.

[0201] For example, combined Figure 10 、 Figure 11 、 Figure 26 and Figure 28 As shown, Figure 28 This is an enlarged schematic diagram of a third subpixel and third partition provided in an embodiment of the present invention. The third subpixel 23 includes a virtual circumscribed quadrilateral 20. The center of gravity Q3 of the orthographic projection of the virtual circumscribed quadrilateral 20 of the third subpixel 23 on the plane of the substrate 1 points toward the center Q4 of the third notch 43 in a direction parallel to the first direction h11 or the second direction h12. The center of the third notch 43 is the midpoint of the line connecting the two endpoints of the third partition 33 forming the third notch 43.

[0202] Figure 10 As an illustration, the third partition portion 33 includes two third notches 43, and the center of gravity of the orthographic projection of the virtual circumscribed quadrilateral of some third sub-pixels 23 on the plane where the substrate 1 is located points to the center of one of the third notches 43 in a direction parallel to the second direction h12, and the center of gravity of the orthographic projection of the other virtual circumscribed quadrilateral of the third sub-pixels 23 on the plane where the substrate 1 is located points to the center of the third notch 43 in a direction parallel to the first direction h11.

[0203] Figure 11 As an illustration, the third partition portion 33 includes two third notches 43 arranged along the first direction h11, the center of gravity of the virtual circumscribed quadrilateral of the third sub-pixel 23 on the plane where the substrate 1 is located points to the center of one of the third notches 43 in a direction parallel to the first direction h11, and the center of gravity of the virtual circumscribed quadrilateral 20 of the third sub-pixel 23 on the plane where the substrate 1 is located points to the center of the other third notch 43 in a direction parallel to the opposite direction of the first direction h11.

[0204] Figure 26For example, the third partition portion 33 includes a third notch 43, and the center of gravity of the orthographic projection of a portion of the third sub-pixels 23 on the plane where the substrate 1 is located points to the center of the third notch 43 in a direction parallel to the second direction h12, while the center of gravity of the orthographic projection of another portion of the third sub-pixels 23 on the plane where the substrate 1 is located points to the center of the third notch 43 in a direction parallel to the first direction h11. Figure 26 and Figure 10 It can be seen that the difference between the two is only the number of the third notches 43, and the other settings are the same. Figure 10 In the embodiment, the third partition portion 43 includes two third notches. Figure 26 In the embodiment, the third partition portion 43 includes only one third notch 43 .

[0205] Figure 28 As an example, the third partition portion 33 includes a third notch 43 , and the center of gravity Q3 of the orthographic projection of the virtual circumscribed quadrilateral 20 of the third sub-pixel 23 on the plane of the substrate 1 points to the center Q4 of the third notch 43 in a direction parallel to the first direction h11 .

[0206] Continue to refer to Figure 11 , wherein the first partition portion 31 includes two first notches 41 corresponding to the sides of the first sub-pixel 21, and the second partition portion 32 includes two second notches 42 corresponding to the sides of the second sub-pixel 22. In combination with the third partition portion 33 and the third notches 43, the areas of the partition portions and the notches can be better balanced, thereby better balancing the effects of suppressing the sub-pixel from being stole and reducing the impedance of the second electrode. In addition, as Figure 11 As shown, the two first notches 41 corresponding to the first sub-pixel 21 are arranged along the second direction h12, the two second notches 42 corresponding to the second sub-pixel 22 are arranged along the second direction h12, and the two third notches 43 corresponding to the third sub-pixel 23 are arranged along the first direction h11. Since the first direction h11 intersects with the third direction h13 and the fourth direction h14 respectively, and the second direction h12 also intersects with the third direction h13 and the fourth direction h14 respectively, the impedance of the second electrode in the third direction h13 and the fourth direction h14 can be reduced, which is beneficial to reducing the voltage drop of the signal transmitted by the second electrode in the third direction h13 and the fourth direction h14, thereby reducing the power consumption of the display panel.

[0207] In an optional embodiment, as Figure 26 As shown, in the embodiment of the present invention, only one third notch 43 can be provided in the third partition portion 33. For two adjacent third sub-pixels 23, as shown in FIG. Figure 26As shown, the embodiment of the present invention can make the center of gravity of the orthographic projection of the virtual circumscribed quadrilateral of one of the third sub-pixels 23 on the plane where the substrate 1 is located point to the center of the third notch 43 in a direction parallel to the first direction h11, and make the center of gravity of the orthographic projection of the virtual circumscribed quadrilateral of another third sub-pixel 23 on the plane where the substrate 1 is located point to the center of the third notch 43 in a direction parallel to the second direction h12, so as to improve the distribution uniformity of the third notches 43 with different orientations in the display panel, thereby improving the transmission consistency of the signal transmitted by the above-mentioned second electrode within the display panel.

[0208] In another optional embodiment, as Figure 1 、 Figure 8 、 Figure 9 、 Figure 10 、 Figure 16 、 Figure 23 、 Figure 25 and Figure 27 As shown, the embodiment of the present invention can also provide at least two third notches 43 in the third partition portion 33. For two third sub-pixels 23 arranged adjacent to each other in the third direction h13, the embodiment of the present invention can arrange the third notches 43 around one third sub-pixel 23 and the third notches 43 around the other third sub-pixel 23 along the third direction h13; the two third notches 43 around one third sub-pixel 23 along the fifth direction h15, and the two third notches 43 around the other third sub-pixel 23 along the sixth direction h16. Based on this arrangement, the distribution uniformity of the third notches 43 in different orientations in the display panel can be improved, thereby improving the transmission consistency of the signal transmitted by the second electrode within the display panel.

[0209] For example, Figure 10 and Figure 27 As shown, in the embodiment of the present invention, the fifth direction h15 can be made parallel to the first direction h11 , and the sixth direction h16 can be made parallel to the second direction h12 .

[0210] Optionally, the embodiment of the present invention can make the number of first notches 41 included in the first partition portion 31 and the number of third notches 43 included in the third partition portion 33 the same, so as to balance the brightness of the first sub-pixel 21 and the third sub-pixel 23, thereby improving the display effect of the display panel. Figure 1 、 Figure 9 、 Figure 10 、 Figure 11 、 Figure 16 、 Figure 20 、 Figure 21 、 Figure 23 and Figure 25As shown, two first notches 41 are provided in the first partition portion 31 around the first sub-pixel 21 , and two third notches 43 are also provided in the third partition portion 33 around the third sub-pixel 23 .

[0211] When the first sub-pixel 21 is a red sub-pixel, the second sub-pixel 22 is a blue sub-pixel, and the third sub-pixel 23 is a green sub-pixel, the inventors Figure 1 、 Figure 7 、 Figure 8 、 Figure 9 、 Figure 10 、 Figure 26 and Figure 27 The scheme shown and Figure 29 and Figure 30 The two embodiments shown were simulated and tested. Figure 29 and Figure 30 and Figure 1 、 Figure 7 、 Figure 8 、 Figure 9 、 Figure 10 、 Figure 26 and Figure 27 The pixel arrangement rules are the same as Figure 1 、 Figure 7 、 Figure 8 、 Figure 9 、 Figure 10 、 Figure 26 and Figure 27 The difference is that in Figure 29 In the embodiment, the first partition part, the second partition part and the third partition part are not provided. Figure 30 In the embodiment, the first partition portion and the third partition portion are not provided, and only the second partition portion is provided.

[0212] The simulation results are shown in Table 1 below. R@B_1 represents the ratio of the red sub-pixel's light intensity to the blue sub-pixel's light intensity when the display panel displays a blue image. A larger value indicates a more severe red sub-pixel's brightening. G@B_1 represents the ratio of the green sub-pixel's light intensity to the blue sub-pixel's light intensity when the display panel displays a blue image. A larger value indicates a more severe green sub-pixel's brightening.

[0213] Table 1

[0215] From Table 1 we can see that Figure 29 and Figure 30 Compared with the method provided, the embodiment of the present invention provides Figure 1 、 Figure 7 、 Figure 8 、 Figure 9 、 Figure 10 、 Figure 26 and Figure 27 The solutions shown can obviously suppress the red and green sub-pixels from being brightened when the blue sub-pixel is lit.

[0216] In addition, the inventors also Figure 1 、 Figure 9 、 Figure 10 and Figure 26 The solution shown was used to simulate the red sub-pixel stealth phenomenon on a green screen, and the results are shown in Table 2. R@G_1 represents the ratio of the red sub-pixel's light intensity to the green sub-pixel's light intensity when the display panel displays a green screen. A larger value indicates a more severe red sub-pixel stealth phenomenon.

[0219] It can be seen from Table 2 that the embodiment of the present invention provides Figure 1 、 Figure 9 、 Figure 10 and Figure 26 The solutions shown can all play the role of suppressing the red sub-pixel from lighting up when the green sub-pixel is lit. Figure 26 In the solution shown, by making the third partition portion 33 include only one third notch 43 , reducing the number of third notches 43 and increasing the length of the non-notch portion in the third partition portion 33 , the red sub-pixel can be significantly suppressed from being brightened.

[0220] In addition, the inventors also Figure 1 、 Figure 9 、 Figure 10 and Figure 26 The display uniformity of the scheme shown was simulated, and the results are shown in Table 3 below. Among them, R@B_2 is used to represent the ratio of the minimum light intensity of the red sub-pixel to the maximum light intensity when the display panel displays a blue image. The larger its value, the better the display uniformity of the red sub-pixel. G@B_2 is used to represent the ratio of the minimum light intensity of the green sub-pixel to the maximum light intensity when the display panel displays a blue image. The larger its value, the better the display uniformity of the green sub-pixel. R@G_2 is used to represent the ratio of the minimum light intensity of the red sub-pixel to the maximum light intensity when the display panel displays a green image. The larger its value, the better the display uniformity of the red sub-pixel.

[0223] From Table 3 we can see that Figure 1 Compared with the scheme shown in the figure, under the blue screen, the embodiment of the present invention provides Figure 9 、 Figure 10 and Figure 26 The solutions shown in the figure can all improve the brightness consistency of the green sub-pixel. Figure 1 The scheme shown is still Figure 9 、 Figure 10 and Figure 26 In the scheme shown, under the green screen, the brightness consistency of the red sub-pixels is relatively high.

[0224] In addition, the inventors also Figure 1 、 Figure 9 、 Figure 10 and Figure 26 The resistance of the second electrode in the solution shown is simulated, and the results are shown in Table 4. RX is used to represent the resistance of the second electrode in the third direction, and RY is used to represent the resistance of the second electrode in the fourth direction.

[0227] It can be seen from Table 4 that the embodiment of the present invention provides Figure 1 、 Figure 9 、 Figure 10 and Figure 26 The solutions shown can all play the role of reducing the resistance of the second electrode, especially in the third direction h13, based on Figure 1 and Figure 9 The provided solutions can reduce the resistance of the second electrode to below 20Ω / □, which can significantly reduce the loss of the signal transmitted by the second electrode during the transmission process, improve display uniformity, and reduce the power consumption of the display panel.

[0228] For example, Figure 31 As shown, Figure 31 A schematic diagram of another display panel provided in an embodiment of the present invention, wherein the display panel 100 further includes a plurality of scan lines 91 and a plurality of data lines 92, wherein the scan lines 91 extend along the third direction h13, and the plurality of scan lines 91 are arranged along the fourth direction h14, and the data lines 92 extend along the fourth direction h14, and the plurality of data lines 92 are arranged along the third direction h13.

[0229] like Figure 31 As shown, the scan line 91 is electrically connected to a plurality of sub-pixels 2 arranged along the third direction h13 , and the data line 92 is electrically connected to a plurality of sub-pixels 2 arranged along the fourth direction h14 .

[0230] For two adjacent scan lines 91, Figure 31As shown, one scan line 91 electrically connects a plurality of first sub-pixels 21 and a plurality of third sub-pixels 23 arranged alternately along a third direction h13, while another scan line 91 electrically connects a plurality of second sub-pixels 22 arranged alternately along a fifth direction h15. Furthermore, the sub-pixels 2 connected to two adjacent scan lines 91 are staggered along a sixth direction h16. Regarding two adjacent data lines 92, one data line 92 electrically connects a plurality of first sub-pixels 21 and a plurality of third sub-pixels 23 arranged alternately along a sixth direction h16, while the other data line 92 electrically connects a plurality of second sub-pixels 22 arranged alternately along a sixth direction h16. Furthermore, the sub-pixels 2 connected to two adjacent data lines 92 are staggered along the fifth direction h15. When the display panel 100 is operating, the data line 92 provides a data voltage, and the multiple scan lines 91 sequentially provide control signals that control the sub-pixels 2 to begin charging, so that the corresponding sub-pixels 2 are charged with the data voltage provided by the data line 92 and illuminated at the desired brightness.

[0231] Optional, such as Figure 32 As shown, Figure 32 A cross-sectional schematic diagram of another display panel provided in an embodiment of the present invention, wherein the light-emitting layer 203 includes a first light-emitting layer 2031 and a second light-emitting layer 2032. The second light-emitting layer 2032 is located on a side of the first light-emitting layer 2031 away from the substrate 1, and the orthographic projection of the second light-emitting layer 2032 on the plane where the substrate 1 is located at least partially overlaps with the orthographic projection of the first light-emitting layer 2031 on the plane where the substrate 1 is located. At least a portion of the first light-emitting layer 2031 and the second light-emitting layer 2032 are located within the opening 80; illustratively, the first light-emitting layer 2031 and the second light-emitting layer 2032 can both be made using a fine metal mask (FMM). The first light-emitting layer 2031 is deposited within the opening 80 of the pixel definition layer 8 and can partially extend outside the opening 80. The first light-emitting layers 2031 of different sub-pixels 2 are independent of each other. The second light-emitting layers 2032 of different sub-pixels 2 are independent of each other.

[0232] For example, the first light-emitting layer 2031 and the second light-emitting layer 2032 may emit light of the same color or different colors.

[0233] like Figure 32 As shown, the sub-pixel 2 further includes a charge generation layer 205 , which is located between the first light-emitting layer 2031 and the second light-emitting layer 2032 .

[0234] For example, Figure 32As shown, the charge generation layer 205 can be disconnected at the location of the partition portion 3. Alternatively, the charge generation layer 205 can also be provided at the partition portion 3 so as to be raised toward the side away from the substrate 1 to increase the transmission path of the lateral leakage current in the charge generation layer 205. Since the conductivity of the charge generation layer 205 is relatively high, if the above-mentioned partition portion 3 is not provided, the charge will migrate laterally between two adjacent sub-pixels 2 through the charge generation layer 205, which may easily cause crosstalk between two adjacent sub-pixels 2, resulting in color deviation of the display panel. In particular, the charge generation layer 205 may easily cause crosstalk between sub-pixels of different colors at low brightness, resulting in low grayscale color deviation. Based on the setting method provided in the embodiment of the present utility model, the problem of low grayscale color deviation can be weakened, and the display effect of the display panel can be improved.

[0235] The display panel 100 provided by the embodiment of the present invention, by designing the sub-pixels 2 to include a series structure comprising a stacked first light-emitting layer 2031 and a second light-emitting layer 2032, can improve the luminance of the sub-pixels 2, reduce the power consumption of the display panel 100, and thus improve the lifespan of the display panel 100. Furthermore, by providing the aforementioned partitioning portion 3 in the display panel 100, the embodiment of the present invention can suppress or isolate lateral leakage current between two adjacent sub-pixels 2, overcome crosstalk between adjacent sub-pixels 2 caused by the high conductivity of the charge generation layer 205, and thus improve the display quality of the display panel 100.

[0236] Optionally, the charge generation layer 205 may include at least one of an N-type charge generation layer and a P-type charge generation layer.

[0237] Based on the same inventive concept, the embodiment of the present utility model further provides a display device, such as Figure 33 As shown, Figure 33 This is a schematic diagram of a display device provided by an embodiment of the present invention, wherein the display device includes the above-mentioned display panel 100. The specific structure of the display panel 100 has been described in detail in the above-mentioned embodiment and will not be repeated here. Figure 33 The display device shown is for illustrative purposes only. The display device may be any electronic device with a display function, such as a mobile phone, a car display screen, a tablet computer, a laptop computer, an e-reader, or a television.

[0238] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.

[0239] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the above embodiments, or replace some or all of the technical features therein with equivalents.
