[0037] Figure 1 A perspective view of a corresponding region of an anode in the related art is shown in FIG. 12A, Figure 2 ​​Fig. 1 shows a top view of a display panel according to an embodiment of the present application, Figure 3 Fig. 1 shows a top view of a display panel according to an embodiment of the present application, Figure 2 Fig. 2 shows an enlarged view of the area W in Fig. 1, Figure 4 Fig. 2 shows an enlarged view of the area W in Fig. 1, Figure 2 Fig. 3 shows a cross-sectional view of AA' in Fig. 1, please refer to Figures 1-4 A display panel 100 comprises:

[0038] A substrate 11 and a plurality of anodes 12 located on one side of the substrate 11.

[0039] A reflection compensation structure 20, the anode 12 comprises a first anode 121, in a direction perpendicular to the plane on which the substrate 11 is located, the first anode 121 overlaps the reflection compensation structure 20, and the reflection compensation structure 20 is located on the side of the first anode 121 facing the substrate 11.

[0040] The present application provides a display panel 100, which comprises a substrate 11 and a plurality of anodes 12 located on one side of the substrate 11, at least including a first anode 121; the display panel 100 further comprises a reflection compensation structure 20, and an optional embodiment provided by the present application is that, in a direction perpendicular to the plane on which the substrate 11 is located, the first anode 121 and the reflection compensation structure 20 can be arranged to overlap, and the reflection compensation structure 20 can be arranged on the side of the first anode 121 facing the substrate 11.

[0041] Fig. 3 shows a cross-sectional view of AA' in Fig. 1, please refer to Figure 1 In the related art, in the display panel, there is a case where a line changing pad 02 is arranged in the area 01 corresponding to at least part of the anode. The line changing pad 02 in the area 01 corresponding to the anode is not necessarily arranged uniformly, for example, the line changing pad 02 arranged in the anode can be located on the second side of the area 01 corresponding to the anode, and there can be no line changing pad 02 arranged on the first side opposite to the second side in the area 01 corresponding to the anode. In addition, the area of the line changing pad 02 is much smaller than the area of each anode corresponding area 01. Therefore, for example Figure 1As shown, when the anode corresponding area 01 is provided with the wire changing pad 02, the anode corresponding area of the wire changing pad 02 at least partially overlapped with the via hole may be recessed to the substrate side. When the light on the light emitting side of the display panel irradiates to the anode side, the reflection effect of the surface of the anode corresponding to the pad part and the surface not provided with the pad part is different. The reflection effect of the surface of the anode corresponding to the wire changing pad 02 part overlapped with the via hole and the surface of the pad part not overlapped with the via hole may also be different. Therefore, the display panel may cause the problem of poor display uniformity due to the difference in reflection effect of the light on the first side and the second side of the anode corresponding area 01.

[0042] It should be noted that Figure 1 The middle circular pattern includes the wire changing pad 02 overlapped with the via hole, specifically the α2 wire changing pad 02 and the α3 wire changing pad 02, and the α1 pad and the α4 pad are not overlapped with the via hole. Although Figure 1 The anode corresponding area 01 only includes two wire changing pads 02 overlapped with the via hole, but the present application is not limited thereto. There may be a case that four circular pattern areas are all wire changing pads 02 overlapped with the via hole. There may be other quantities, for example, the anode corresponding area 01 may include three, five, six, eight or the like. The present application does not make specific limitation thereto.

[0043] It should be noted that, as Figure 1 As shown, there is a wire changing pad 02 overlapped with the via hole, which can be recessed to the substrate side in the form of a metal plane during manufacturing.

[0044] At this time, the present application provides a scheme as shown in Figures 2-4 As shown, the first anode 121 corresponding area 03 can be provided with a reflection compensation structure 20. The reflection compensation structure 20 can be provided on the first side of the first anode 121 corresponding area 03, so that the reflection compensation structure 20 and Figure 1The positions of the original pads in the display panel shown are combined to be as evenly as possible or as symmetrically as possible in the region 03 corresponding to the first anode 121, and the addition of the reflection compensation structure 20 can be used to reflect and adjust the light rays irradiated from the light-emitting side of the display panel 100 to the side of the substrate 11 to the side surface of the first anode 121 away from the substrate 11, so that in the region 03 where the first anode 121 is located, the part of the first anode 121 corresponding to the pads away from the substrate 11 has a relatively uniform reflection effect on the light rays, thereby making the reflection effect of the first anode 121 on the light rays incident thereon more uniform, avoiding a large difference in the reflection effect of the first anode 121 on the light rays on the first side and the second side, thereby reducing or avoiding the color cast problem in the display area corresponding to the first anode 121, and improving the display uniformity of the display panel 100.

[0045] It should be noted that the display panel 100 of the present embodiment Figures 2-4 Only a schematic view of the display panel 100 including the substrate 11, the anode 12, and the reflection compensation structure 20 is shown by way of example, and in actual implementation, the structure of the display panel includes but is not limited to this, and the display panel can also include other structures, such as the film layer structure, the pixel circuit, the driving circuit, and the like of the display panel, wherein the pixel circuit and the driving circuit can generally be disposed on the side of the anode facing the substrate. Specifically, please refer to Figure 4 As shown, the display panel 100 can include the substrate 11, the first metal material layer L1 disposed on the side of the substrate 11 facing the anode 12, the capacitor metal layer L0, the second metal material layer L2, the third metal material layer L3, the fourth metal material layer L4, and the like, and the adjacent metal material layers are separated by an insulating layer GI to avoid the crosstalk problem between electrical signals. Optionally, along the thickness direction of the display panel, the capacitor metal layer L0 is located between the first metal layer L1 and the second metal layer L2, the third metal layer L3 is located on the side of the second metal layer L2 facing the anode 12, and the fourth metal layer L4 is located on the side of the third metal layer L3 facing the anode 12. When the display panel includes a transistor, optionally, the gate of the transistor can be located on the first metal layer L1, and the source and the drain can be located on the second metal layer L2. At least part of the metal on the capacitor metal layer L0 can be used to overlap with part of the metal on the first metal layer L1 or the second metal layer L2 to form a capacitor structure, for example, to form a storage capacitor of a pixel circuit on the display panel. In addition, the first metal layer L1, the capacitor metal layer LC, the second metal layer L2, the third metal layer L3, and the fourth metal layer L4 can be used to layout signal lines.

[0046] Further, the display panel provided by the embodiment can be a display panel using an organic light-emitting diode display technology, i.e., an OLED (Organic Light-Emitting Diode) display panel, as shown in Figure 4 As shown, the display panel includes a substrate 11, an array layer 92, and a light-emitting layer 93, and further includes an encapsulation layer on the side of the light-emitting layer 93 away from the substrate 11. The basic structure of the light-emitting layer 93 of the OLED display panel includes an anode 12, a light-emitting layer 125, and a cathode 126, wherein the light-emitting layer 125 and the cathode 126 are sequentially arranged on the side of the anode 12 away from the substrate 11. When a proper voltage is supplied by a power supply, holes of the anode 12 and electrons of the cathode 126 will combine in the light-emitting layer 125 to generate bright light. Compared with a thin-film field-effect transistor liquid crystal display, the OLED display device has the characteristics of high visuality and high brightness, and is more power-saving, light in weight, and thin in thickness. Of course, in some other embodiments of the present application, the display panel can also be a display panel using an inorganic light-emitting diode display technology, such as a Micro LED display panel, or a Mini LED display panel, etc., which is not specifically limited in the present application.

[0047] It should be further noted that the reflection compensation structure 20 provided in the present application can be arranged in the third metal material layer L3 in the display panel 100, and the reflection compensation structure 20 can be used to be electrically connected with other structural members as a medium for transmitting electrical signals, or can not be electrically connected with other structural members, and only exists as a film layer structure. In addition, the reflection compensation structure 20 can be arranged as a planar plate structure according to requirements, or itself includes a recessed structure recessed towards the substrate, or itself includes a block structure overlapping with a via hole including a recessed hole towards the substrate.

[0048] No matter how the reflection compensation structure 20 is arranged, no matter whether the reflection compensation structure 20 is electrically connected with other structural members, as long as the reflection compensation structure 20 arranged in the region 03 corresponding to the first anode 121 can be used to compensate the reflection of the first anode 121, the display panel provided by the embodiment can be used to solve the problem of the display panel provided by the prior art. Figure 1The positions of the original pads in the display panel are combined to be arranged as evenly as possible or as symmetrically as possible in the region 03 corresponding to the first anode 121. When the reflection compensation structure and / or the pad are arranged on the first side and the second side of the region 03 corresponding to the first anode 121 respectively, the reflection compensation structure and / or the pad can be arranged such that the anode 12 in the region corresponding to the reflection compensation structure and / or the pad has the same or similar degree of concave or convex away from the surface of the substrate 11. Therefore, the first side and the second side of the region 03 corresponding to the side surface of the anode 12 away from the substrate 11 can be concave or convex as evenly as possible or as symmetrically as possible, that is, the reflection degree and the reflection direction of the light irradiated to the surface of the first side and the second side of the region 03 corresponding to the side surface of the anode 12 away from the substrate 11 are quite similar. In order to avoid the situation that one side of the first side and the second side is concave or convex, and the other side is flat, the reflection degree and the reflection direction of the light irradiated to the surface of the first side and the second side of the anode are quite different, thereby facilitating to improve the reflection uniformity of the anode 12 in the display panel, reducing or avoiding the color cast problem in some display areas corresponding to the anode 12, and improving the display uniformity of the display panel 100.

[0049] For example, when the first anode 121 of the display panel 100 corresponds to the region 03 originally provided with the pad biased to the first side in the region, and the pad, such as the wire-changing pad 02 overlapping the via, exists, the existence of the wire-changing pad 02 can cause the corresponding region of the first anode 121 to exist the problem of recessing toward the substrate 11 side. In this case, the reflection compensation structure 20 can be additionally provided in the region 03 biased to the second side in the region, and the reflection compensation structure 20 is symmetrically provided with the wire-changing pad 02. The reflection compensation structure 20 has the recessing structure toward the substrate 11 side, or the reflection compensation structure 20 is a block structure, and has a recessing hole toward the substrate 11 side. Thus, the corresponding region of the first anode 121 of the reflection compensation structure 20 can also exist the problem of recessing toward the substrate 11 side. Specifically, for example, two reflection compensation structures 20 and four wire-changing pads 02 can be provided in the region 03. The reflection compensation structure 20 and the wire-changing pad 02 have the recessing structure toward the substrate 11 side, or have a recessing hole toward the substrate 11 side. Thus, the first side and the second side in the region 03 corresponding to the surface of the first anode 121 away from the substrate 11 side can have the recessing structure as symmetric as possible. Thus, the anode 12 of the first side and the second side has the nearly same reflection effect on the light irradiated toward the surface away from the substrate 11 side. Similarly, when the first anode 121 of the display panel 100 corresponds to the region 03 originally provided with the pad biased to the first side in the region, and the existence of the pad can cause the corresponding region of the first anode 121 to exist the problem of protruding away from the substrate 11 side, the reflection compensation structure 20 can be additionally provided in the region 03 biased to the second side in the region, and the reflection compensation structure 20 is symmetrically provided with the pad. The additional reflection compensation structure 20 can cause the corresponding region of the first anode 121 to protrude away from the substrate 11 side. Thus, the first side and the second side in the region 03 corresponding to the surface of the first anode 121 away from the substrate 11 side can have the protruding structure as symmetric as possible. Thus, the anode 12 of the first side and the second side has the nearly same reflection effect on the light irradiated toward the surface away from the substrate 11 side.

[0050] It should be further noted that, Figure 2 The display panel is taken as the circular rectangular shape as an example to describe the embodiment. In some other embodiments of the present application, the shape of the display panel can also be other shapes, such as the rectangular shape, the circular shape, the elliptical shape, or any other feasible shape. Figure 2 、 Figure 3 The region 03 is taken as the rectangular shape as an example to describe the embodiment. In some other embodiments of the present application, the shape of the region 03 can also be other shapes, such as the circular shape, the triangular shape, the hexagonal shape, or any other feasible shape. Figure 2 、Figure 3 The present embodiment is described by taking the wire changing pad and the reflection compensation structure 20 as a circular shape as an example. In some other embodiments of the present application, the wire changing pad and the reflection compensation structure can also have other shapes, such as a rectangular shape, a triangular shape, a hexagonal shape, or any other possible shape.

[0051] It should be noted that the present application Figure 4 In the cross-sectional view shown, the anode 12 is shown as having a planar reflection compensation structure 20 and a planar wire changing pad on the side close to the substrate 11. However, this is only one of the possible ways of arranging the material layers on the side close to the first anode 121 in the first anode 121 area 03. The present application does not limit the structure type of the reflection compensation structure 20 and the wire changing pad in the first anode 121 area 03, and the user can set the specific structure type of the reflection compensation structure 20 and the wire changing pad in the first anode 121 area 03 according to the requirements.

[0052] Please continue to refer to Figures 2-4 Optionally, the display panel further comprises:

[0053] The plurality of pixel opening regions 30 include a first pixel opening region 31. In the direction perpendicular to the plane on which the substrate 11 is located, the reflection compensation structure 20 overlaps the first pixel opening region 31.

[0054] The display panel 100 can further include a plurality of pixel opening regions 30, and the first pixel opening region 31 can be included in the pixel opening regions 30. The reflection compensation structure 20 can be arranged to overlap the first pixel opening region 31 in a direction perpendicular to the plane on which the substrate 11 is located. The light-emitting element can be arranged in the pixel opening region 30, and the light-emitting element can include a cathode 126, a light-emitting layer 125, and an anode 12 arranged in a stack. That is, the anode 12 is arranged in the pixel opening region 30. The reflection compensation structure 20 can be arranged in the first pixel opening region 31. When the first pixel opening region 31 itself includes a pad, the reflection compensation structure 20 and the pad in the first pixel opening region 31 can be arranged as uniformly as possible or as symmetrically as possible in a region corresponding to the first anode 121 in the first pixel opening region 31. The reflection compensation structure 20 can be arranged to adjust the degree of concave or convex of the surface of the first anode 121 away from the substrate 11 together with the pad, so as to adjust the light reflected from the surface of the first anode 121 on the side of the display panel 100 to the side of the substrate 11. The reflection effect of the part of the first anode 121 in the first pixel opening region 31 corresponding to the reflection compensation structure 20 and the pad can be equivalent, so that the reflection effect of the light incident on the first pixel opening region 31 is more uniform, and the difference in reflection effect of the light between at least two sub-regions in the first pixel opening region 31 is avoided, so as to reduce or avoid the color cast problem in the display area corresponding to the first pixel opening region 31, and improve the display uniformity of the display panel 100.

[0055] Figure 5 An enlarged view of the Q region in the embodiment of the application is shown in FIG. 6. Figure 2 Figures 2-5 Optionally, the display panel further includes:

[0056] The first signal trace 41 extends in a first direction, and the second signal trace 42 extends in a second direction, and the first direction intersects the second direction.

[0057] In a direction perpendicular to the plane on which the substrate 11 is located, the first signal trace 41 overlaps the first anode 121 and is located on the side of the first anode 121 facing the substrate 11.

[0058] In the second direction, the reflection compensation structure 20 is located at least on the first side of the first signal trace 41.

[0059] ​This application also provides an alternative implementation in which the display panel 100 further includes a first signal trace 41 and a second signal trace 42, wherein the first signal trace 41 extends along a first direction, and the second signal trace 42 extends along a second direction intersecting the first direction. The first direction and the second direction can be optionally configured to be perpendicular to each other. In this case, the first signal trace 41 and the first anode 121 can be arranged in a direction perpendicular to the plane where the substrate 11 is located, and the first signal trace 41 can be arranged on the side of the first anode 121 facing the substrate 11. Along the second direction, the reflection compensation structure 20 added to the display panel 100 can be arranged on the first side of the first signal trace 41.

[0060] Here, one alternative implementation method is provided, such as... Figure 5 As shown, a pad unit group 04 may include four pads arranged in a rectangular shape. In the region 03 where the first anode 121 is located, there are a first side region and a second side region arranged opposite each other in the second direction. Two pads are located between the first side region and the second side region of the first anode 121, and the other two pads are located in the second side region of the first anode 121. One of the two pads located between the first side region and the second side region may be electrically connected to the first signal trace 41. In this case, the reflection compensation structure 20 added to the display panel 100 may be optionally located at least in the first side region of the first anode 121 along the second direction. With this configuration, in the region 03 corresponding to the first anode 121, two pads are arranged between the first and second side regions along the second direction. Two pads are arranged in the second side region, and two reflection compensation structures 20 are arranged in the first side region. Thus, along the second direction and / or along the first direction, the pads and reflection compensation structures 20 can be symmetrically arranged in the region 03 corresponding to the first anode 121. The reflection compensation structures 20 and the pads together adjust the degree of concavity or convexity of the surface of the first anode 121 on the side away from the substrate 11 in their corresponding regions. This design ensures that the reflection effect of the portion of the region 03 where the first anode 121 is located, corresponding to the reflection compensation structure 20 and the pad, is comparable. This makes the reflection effect of the surface on the side of the region 03 corresponding to the first anode 121 away from the substrate 11 more uniform, avoiding a large difference in the reflection effect of the first side and the second side of the surface on the side of the first anode 121 away from the substrate 11. This reduces or avoids the color shift problem in the display area corresponding to the first anode 121 and improves the display uniformity of the display panel 100.

[0061] One specific implementation method is as follows: Figure 5When the four pads in the pad unit group 04 shown in the figure include a recessed structure on the side of the substrate 11, two reflection compensation structures 20 can also be provided, which also include a recessed structure on the side of the substrate 11. In this case, the reflection compensation structure 20 and the pad unit group 04 together adjust the degree of recess on the side of the first anode 121 away from the substrate 11 in their corresponding areas, so that the part of the area 03 where the first anode 121 is located has the reflection effect of the reflection compensation structure 20 and the pad unit group 04 is equally good, thereby making the reflection effect of the surface of the first anode 121 away from the substrate 11 on the incident light more uniform.

[0062] Figure 6 The image shown is provided in an embodiment of this application. Figure 2 A magnified view of region C in the middle; please refer to it. Figure 2 , Figure 4 Reference Figure 6 Here, another alternative implementation method is provided, such as Figure 1 As shown in region C, a pad unit group 04 may include four pads arranged in a rectangular shape. The first anode 121 includes a first side region and a second side region arranged opposite each other in the second direction. Two pads are located in the second side region of the first anode 121, and two other pads are located outside the region 03 where the first anode 121 is located, that is, on the side of the second side region of the first anode 121 away from its first side region. One of the two pads located in the second side region may be electrically connected to the first signal trace 41. In this case, the reflection compensation structure 20 added to the display panel 100 may be optionally located at least in the first side region of the first anode 121 along the second direction. With this configuration, in the region 03 corresponding to the first anode 121, two pads are provided in the second side region along the second direction, and two reflection compensation structures 20 are provided in the first side region. Thus, along the second direction and / or along the first direction, the pads and reflection compensation structures 20 can be symmetrically arranged in the region corresponding to the first anode 121. The reflection compensation structures 20 and the pads together adjust the degree of concavity or convexity of the surface of the first anode 121 on the side away from the substrate 11 in its corresponding region. This makes the reflection effect of the reflection compensation structures 20 and the pads in the region 03 corresponding to the first anode 121 on light comparable. As a result, the reflection effect of the surface on the side away from the substrate 11 in the region 03 corresponding to the first anode 121 on the incident light is more uniform. This avoids the situation where there is a large difference in the reflection effect of the first side and the second side of the first anode 121 on light, thereby reducing or avoiding the color shift problem in the display area corresponding to the first anode 121 and improving the display uniformity of the display panel 100.

[0063] Please continue to refer to Figures 2-6Optionally, further comprising:

[0064] The conductive pad 50 overlaps the first anode 121 in a direction perpendicular to the plane where the substrate 11 is located, and is located on the side of the first anode 121 facing the substrate 11;

[0065] At least one conductive pad 50 is located on the second side of the first signal trace 41 in the second direction, wherein the first side and the second side are opposite; and / or,

[0066] At least one conductive pad 50 overlaps the first signal trace 41 in a direction perpendicular to the plane where the substrate 11 is located. The conductive pad in this application can be understood as a wire change pad 02.

[0067] An optional implementation is provided, for example, in the related art, the display panel includes a wire change pad 02 in the anode corresponding area 01, which is not necessarily uniformly arranged in the anode corresponding area 01, and the number of wire change pads 02 arranged in the anode corresponding area 01 is also uncertain; for example, refer to Figure 1 If the area 01 only includes α2 wire change pads 02 and α3 wire change pads 02, then the area 01 only includes wire change pads 02 located in the middle area between the first side and the second side, the left side, and the wire change pads 02 located in the second side, the right side, then the wire change pads 02 in the area 01 cannot be arranged relatively uniformly or symmetrically in the area, then the surface of the anode 12 corresponding to the area 01 away from the substrate 11 side will have a problem that the reflection effect of light on the surface of the area where the α2 wire change pad 02 and the α3 wire change pad 02 are arranged is different from the reflection effect of light on the surface of the area where the wire change pad 02 is not arranged, which will cause the reflection effect of light on different areas of the surface of the anode 12 corresponding to the area 01 away from the substrate 11 side to be different, which will cause the area 01 of the corresponding display panel to present a display picture with differences, resulting in display unevenness of the display panel. In addition, there may also be a case where no wire change pad 02 is arranged in part of the area 01. Therefore, the area 01 included in the display panel has the following arrangement situations: one is that the wire change pad 02 is arranged in part of the area 01 and is arranged relatively symmetrically or uniformly; the second is that the wire change pad 02 is arranged in part of the area 01, but the wire change pad 02 is arranged asymmetrically or non-uniformly in the area 01; the third is that no wire change pad 02 is arranged in part of the area 01; due to the different arrangement situations of the wire change pad 02 in the multiple areas 01, the reflection effect of light on the surface of the anode 12 corresponding to the area 01 away from the substrate 11 side will be different, resulting in display unevenness of the display panel.

[0068] Therefore, for the case that the wire-changing pads 02 are arranged in disorder or not arranged in the partial area 01, the display panel 100 can further include the conductive pads 50, which can be arranged to have an overlapping area with the first anodes 121 in the direction perpendicular to the plane where the substrate 11 is located, and the conductive pads 50 can be arranged to be located on the side of the first anodes 121 facing the substrate 11. That is, the area 03 corresponding to the first anodes 121 can be arranged with the conductive pads 50 and the reflection compensation structures 20.

[0069] With reference to Figure 5 、 Figure 6 When the conductive pads 50 and the reflection compensation structures 20 are arranged in the area 03, the conductive pads 50 and the reflection compensation structures 20 can be arranged to be as symmetrical as possible or as uniform as possible in the area 03, and the structure of the conductive pads 50 and the reflection compensation structures 20 can be adjusted, that is, whether the conductive pads 50 and the reflection compensation structures 20 include the recessed structure recessed to the side of the substrate 11 or whether the conductive pads 50 and the reflection compensation structures 20 include other structures that can cause the conductive pads 50 and the reflection compensation structures 20 to be recessed to the side of the substrate 11, so that the combination of the conductive pads 50 and the reflection compensation structures 20 can make the surfaces of the first anodes 121 corresponding to the conductive pads 50 and the reflection compensation structures 20 have the same degree of slight convexity or slight concavity, so that the surfaces of the first anodes 121 corresponding to the conductive pads 50 and the reflection compensation structures 20 have the same reflection effect on the light.

[0070] It should be noted that the conductive pads 50 included in the display panel 100 can be selected to be electrically connected with some signal wires to realize the transmission of corresponding electrical signals required when the display panel 100 works. Of course, the conductive pads 50 can also include the case that they are not used, that is, the conductive pads 50 are not electrically connected with any wires or structures.

[0071] At this time, a specific embodiment is provided, please refer to Figure 5The display panel 100 includes a first signal trace 41 extending along a first direction, for example, a first anode 121 corresponding to a region 03, and a conductive pad 50 in the region 03 has an overlapping area with the first signal trace 41 in a direction perpendicular to the plane of the substrate 11, and the conductive pad 50 is electrically connected to the first signal trace 41. Meanwhile, the region 03 where the first anode 121 is located also includes a conductive pad 50 in the second side of the region 03 in the second direction. The two conductive pads 50 in the second side region are arranged in the second side region of the first signal trace 41, and the reflection compensation structure 20 is arranged in the first side region of the first signal trace 41 along the second direction. Then, the four conductive pads 50 and the two reflection compensation structures 20 in the region 03 corresponding to the first anode 121 are symmetrically arranged in the region corresponding to the first anode 121 along the second direction or along the first direction. Through the reflection compensation structure 20 and the conductive pad 50 arranged in the region 03 corresponding to the first anode 121, the structure can be further adjusted to make the side surface of the first anode 121 away from the substrate 11 have relatively uniform or symmetric distribution of micro convex or micro concave, so that the reflection effect of the side surface of the first anode 121 away from the substrate 11 to the incident light is more uniform, avoiding the case that the reflection effect of the first side and the second side of the first anode 121 to the light is greatly different, thereby reducing or avoiding the color cast problem in the display area corresponding to the first anode 121, and improving the display uniformity of the display panel 100.

[0072] In addition, please refer to Figure 5 When the region 03 includes six circular structures as shown in Figure 5 , any one of the six circular structures can be designed to be at least one of the conductive pad 50 and the reflection compensation structure 20. As long as the conductive pad 50 and / or the reflection compensation structure 20 included in the region 03 can be as symmetrically and / or as uniformly as possible in the region, so that the side surface of the first anode 121 away from the substrate 11 has relatively uniform or symmetric distribution of micro convex or micro concave, the reflection effect of the side surface of the first anode 121 away from the substrate 11 to the incident light is more uniform.

[0073] Another specific embodiment is also provided, please refer to Figure 6The display panel 100 includes a first signal trace 41 extending along a first direction, for example, a first anode 121 corresponding area 03 exists a conductive pad 50 in the vertical direction of the substrate 11 plane with the first signal trace 41 has an overlapping area, and is electrically connected with the first signal trace 41, while the conductive pad 50 electrically connected with the first signal trace 41 is located in the second side area of the area 03 where the first anode 121 is located, when the reflection compensation structure 20 is at least located in the first side area of the first anode 121 along the second direction, then the area corresponding to the first anode 121, two conductive pads 50 and two reflection compensation structures 20 are symmetrically arranged in the area corresponding to the first anode 121 along the second direction or along the first direction, through the reflection compensation structure 20 and the conductive pad 50 arranged correspondingly in the area 03 where the first anode 121 is located, the side surface of the first anode 121 away from the substrate 11 has relatively uniform or symmetrically distributed pico convex or pico concave, so that the reflection effect of the surface of the first anode 121 away from the substrate 11 to the incident light is more uniform, avoiding the case that the reflection effect of the first side and the second side of the first anode 121 to the light is greatly different, thereby reducing or avoiding the color cast problem existing in the display area corresponding to the first anode 121, and improving the display uniformity of the display panel 100.

[0074] In addition, please refer to Figure 6 When the area 03 includes four circular structures as shown, the four circular structures can be at least one of the conductive pad 50 and the reflection compensation structure 20 according to the design, as long as the conductive pad 50 and / or the reflection compensation structure 20 included in the area 03 can be as symmetrically as possible or as uniformly as possible in the area, so that the side surface of the first anode 121 away from the substrate 11 has relatively uniform or symmetrically distributed pico convex or pico concave, that is, the reflection effect of the side surface of the first anode 121 away from the substrate 11 to the incident light is more uniform.

[0075] It should be noted that, Figure 5 , Figure 6 Only two possible cases of the setting position of the reflection compensation structure 20 and the conductive pad 50 are shown, and the specific setting structure, shape, size and number of the reflection compensation structure 20 and the conductive pad 50 are not shown.

[0076] Figure 7 An enlarged view of the D area in the Figure 2 provided by the embodiment of the application is shown, Figure 8 A schematic diagram of a pixel circuit provided by the embodiment of the application is shown, please refer to Figure 2 , Figure 4 Please refer to Figure 7Optionally, the display panel 100 further comprises:

[0077] The third signal line 43 is arranged in the same layer as the second signal line 42 and extends in the same direction as the second signal line 42.

[0078] The conductive pad 50 is electrically connected to the second signal line 42 or the third signal line 43.

[0079] Further, the display panel 100 can further comprise the third signal line 43, the third signal line 43 and the second signal line 42 can both extend in the second direction, or the third signal line 43 and the second signal line 42 can be arranged in the same layer. In the display panel 100, some of the conductive pads 50 can be electrically connected to the second signal line 42, or some of the conductive pads 50 can be electrically connected to the third signal line 43.

[0080] It should be noted that the display panel 100 comprises a pixel circuit, which is electrically connected to a sub-pixel in the display panel, and the pixel circuit receives an electrical signal to control whether the corresponding sub-pixel is in a display state or not. As shown in Figure 8 The pixel circuit 70 can comprise a data writing module 701, a first light emitting control module 7021, a second light emitting control module 7022, a reset module 703, and a compensation module 704. The specific working principle of the pixel circuit 70 is as follows. In the initialization stage, the transistor T5 is turned on, and the transistor T7 is turned off. The voltage of the first initialization signal end VREF is transmitted to the first node N1 by the transistor T5, and the driving transistor T2 is initialized. In the data writing stage, the transistors T5 and T7 are both turned off, the transistors T3 and T6 are turned on, and the data signal end DATA receives the data signal transmitted by the data signal line to the second node N2. The signal of the second node N2 is transmitted to the third node N3 by the driving transistor T2, and the signal of the third node N3 is transmitted to the first node N1 by the transistor T3, so that the potential of the first node N1 is raised. In the light emitting stage, the transistors T3 and T6 are turned off, the transistors T1 and T4 are turned on, and the driving current generated by the driving transistor T2 is transmitted to the light emitting element OLED1, so that the light emitting element OLED1 emits light. It should be noted that Figure 8 Only one 7T1C mode circuit structure of the pixel circuit 70 is shown, but the present application is not limited thereto. The specific circuit structure of the pixel circuit can be adjusted as required. Furthermore, the pixel circuit can also be embodied as 8T1C, 9T2C, etc., which is not limited by the present application.

[0081] In an alternative embodiment, the second signal line 42 is a data signal line in the display panel 100. Please refer to Figure 8, the second signal wire 42 will be electrically connected to the first electrode of the transistor T6 of the data writing module 701 in the pixel unit 70, i.e. to the DATA end in Figure 8 . In an alternative embodiment, the conductive pad 50 can be electrically connected to the second signal wire 42 in the film layer structure of the display panel 100, which can be used to transmit the electrical signal transmitted by the data signal wire to the corresponding pixel unit through the conductive pad 50.

[0082] In an alternative embodiment, the third signal wire 43 can be a PVEE signal line (power voltage signal line), as shown in Figure 7 , the first conductive pad 50 from left to right in the first direction and the first conductive pad 50 from top to bottom in the second direction is electrically connected to the third signal wire 43, i.e. the connection between the third signal wire 43 and the conductive pad 50 is shown in the perspective view. When the third signal wire 43 and the conductive pad 50 are arranged in different layers, the electrical connection between the third signal wire 43 and the conductive pad 50 can be realized by setting a via, which is equivalent to connecting the third signal wire 43 in parallel, which is beneficial to reduce the overall impedance of the third signal wire 43 and reduce the load. In addition, in a possible embodiment, when the third signal wire 43 and the conductive pad 50 are arranged in the same layer, the third signal wire 43 and the conductive pad 50 can be directly electrically connected, which is equivalent to increasing the area of the third signal wire 43, which is also beneficial to reduce the impedance and reduce the load.

[0083] In addition, it should be noted that in addition to being used as a PVEE signal line, the third signal wire 43 can also be used as an auxiliary signal line for transmitting electrical signals to the data signal line, such as the FIAA wire extending in the second direction. In addition, the third signal wire 43 can be set as a PVEE signal line in some segments and as an auxiliary signal line for transmitting electrical signals to the data signal line in some segments. The specific function of the third signal wire 43 in the panel can be selected by the user according to the actual needs.

[0084] It should be noted that the conductive pad 50 included in the display panel 100 can be used to electrically connect to the data signal line, the power voltage signal line, the FIAA wire, etc. This is only an alternative setting provided by the present application, and the present application is not limited thereto. The user can select the signal line to which the conductive pad 50 is electrically connected according to the actual needs, and some conductive pads 50 can also be set to be floating and not electrically connected to any signal line.

[0085] Please continue to refer to Figure 2 , Figure 4 , Figure 7Optionally, the reflection compensation structure 20 is electrically connected with the second signal line 42 or the third signal line 43.

[0086] When the reflection compensation structure 20 is arranged in the display panel 100, an optional implementation is that the second signal line 42 can be arranged as a data signal line in the display panel 100, and the reflection compensation structure 20 can be reused as a conductive pad when required by the design of the display panel. Please refer to Figure 7 The second reflection compensation structure 20 from left to right in the first direction is electrically connected with the second signal line 42, that is, the connection between the second signal line 42 and the reflection compensation structure 20 is shown by a perspective view. Arranging the reflection compensation structure 20 to be electrically connected with the second signal line 42 can be used to realize that the electrical signal transmitted by the data signal line is transmitted to the corresponding pixel unit through the reflection compensation structure 20. An optional implementation is provided as follows. Please refer to Figure 7 The third signal line 43 can be a PVEE signal line (power voltage signal line) for example, and the reflection compensation structure 20 can also be arranged to be electrically connected with the third signal line 43 when required. When the third signal line 43 is arranged in a different layer from the conductive pad 50, the electrical connection between the third signal line 43 and the conductive pad 50 can be realized by arranging a via, which is equivalent to connecting the third signal line 43 in parallel with a signal, and is beneficial to reduce the overall impedance of the third signal line 43 and reduce the load. In addition, a possible implementation is provided as follows. When the third signal line 43 is arranged in the same layer as the conductive pad 50, the third signal line 43 can be arranged to be directly electrically connected with the conductive pad 50, which is equivalent to increasing the area of the third signal line 43, and is also beneficial to reduce the impedance and reduce the load.

[0087] In addition, it should be noted that the third signal line 43 can be used as a PVEE signal line, and can also be arranged as an auxiliary signal line for transmitting an electrical signal to a data signal line, such as a FIAA line extending in the second direction. In this application, the specific function of the third signal line 43 in the panel is not limited, and the user can select and set the specific function of the third signal line 43 in the panel according to the actual needs.

[0088] It should be noted that the reflection compensation structure 20 included in the display panel 100 can be used to be electrically connected with a data signal line, a power voltage signal line, a FIAA line, etc., which is only an optional setting mode provided by the present application, and the present application is not limited thereto. The user can select the signal line to which the reflection compensation structure 20 is electrically connected according to the actual needs, and in addition, some reflection compensation structures 20 can be arranged to be floating and not electrically connected with any signal line.

[0089] Figure 9 Fig. 2 shows a cross-sectional view of the VV' in an embodiment of the present application, which can be referred to in conjunction with Fig. 1. Figure 2 Figure 2 Figure 9 Optionally, the reflection compensation structure 20 is arranged in the same layer as the conductive pad 50.

[0090] The present application further provides an alternative embodiment, when the display panel 100 comprises both the conductive pad 50 and the reflection compensation structure 20, the reflection compensation structure 20 and the conductive pad 50 are arranged in the same layer and manufactured by the same process, so as to avoid the increase of the overall thickness of the display panel 100 caused by the different layers of the reflection compensation structure 20 and the conductive pad 50, and to simplify the manufacturing process of the display panel 100.

[0091] Of course, the arrangement of the reflection compensation structure 20 and the conductive pad 50 in the same layer and by the same process is only one alternative arrangement provided by the present application, and the present application does not make a specific limitation thereon, and the user can select the arrangement of the reflection compensation structure 20 and the conductive pad 50 in the display panel 100 according to the actual needs.

[0092] Figure 10 Fig. 3 shows another cross-sectional view of the VV' in an embodiment of the present application, which can be referred to in conjunction with Fig. 1. Figure 2 Fig. 4 shows another cross-sectional view of the VV' in an embodiment of the present application, which can be referred to in conjunction with Fig. 1. Figure 11 Fig. 5 shows another cross-sectional view of the VV' in an embodiment of the present application, which can be referred to in conjunction with Fig. 1. Figure 2 Fig. 6 shows another cross-sectional view of the VV' in an embodiment of the present application, which can be referred to in conjunction with Fig. 1. Figure 2 Figure 10 Figure 11 Optionally, the display panel 100 further comprises a first via hole 61, the conductive pad 50 comprises a first conductive pad 501 and a second conductive pad 502, the first via hole 61 is in contact with the first conductive pad 501 and is located on the side of the first conductive pad 501 facing the substrate 11.

[0093] ​​​​This application also provides an alternative embodiment in which the conductive pads 50 included in the display panel 100 may include a first conductive pad 501 and a second conductive pad 502. Another alternative embodiment is that the display panel 100 includes a first via 61, which can be formed by partially recessing at least one insulating layer GI on the side of the first conductive pad 501 facing the substrate 11 towards the substrate 11. For example, when the first conductive pad 501 needs to be electrically connected to a portion of a signal trace, the signal trace is disposed in a certain insulating film layer on the side of the first conductive pad 501 facing the substrate 11. In this case, the recessed bottom of the first via 61 on the side of the first via 61 facing the substrate 11 can connect with the surface of the corresponding signal trace away from the substrate 11. Therefore, when the first conductive pad 501 is formed on the surface of the first via 61 away from the substrate 11, the first conductive pad 501 can be formed on the side surface and the recessed bottom of the insulating layer GI corresponding to the first via 61, realizing the electrical connection between the first conductive pad 501 and its corresponding signal trace.

[0094] Furthermore, when conductive pads 50 and reflection compensation structures 20 are correspondingly provided in the same region 03 where the first anode 121 is located, since the conductive pads 50 and / or reflection compensation structures 20 are electrically connected to signal traces disposed on different layers, the conductive pads 50 and / or reflection compensation structures 20 include recessed positions that are recessed towards the substrate 11. The reflection effect of the surface area of ​​the first anode 121 away from the substrate 11 in the region corresponding to the conductive pads 50 and / or reflection compensation structures 20 with recessed positions on the light incident on its surface is different from the reflection effect of the surface area of ​​the first anode 121 away from the substrate 11 in the region corresponding to the conductive pads 50 and / or reflection compensation structures 20 with planar structures on the light incident on its surface. Therefore, as Figure 11 As shown, it is possible to optionally configure all conductive pads 50 and / or all reflection compensation structures 20 in the region 03 where the first anode 121 is located to have recessed positions facing the substrate 11. This allows the reflection effect of the surface of the first anode 121 away from the substrate 11 on the light incident on its surface to be almost the same in all the conductive pads 50 and reflection compensation structures 20 in the region 03 where the first anode 121 is located. This makes the reflection effect of the surface of the first anode 121 away from the substrate 11 on the light incident on its side more uniform, avoiding the situation where there are large differences in the reflection effect of light at different positions on the surface of the first anode 121 away from the substrate 11. This reduces or avoids the color shift problem in the display area corresponding to the first anode 121 and improves the display uniformity of the display panel 100.

[0095] It should be added that, Figure 10 , Figure 11Only the substrate 11, the first anode 121, the conductive pad 50 and the reflection compensation structure 20 included in the film layer structure of the display panel are shown, other unmarked film layer structures of the first anode 121 towards the substrate 11 side are some insulating layers GI, as for the structure such as transistor, capacitor which can be included between the first anode 121 and the substrate 11, they are not shown here, which can be referred to Figure 4 or Figure 9 The embodiments shown set the structure such as transistor, capacitor, or the user can set other structures included in the film layer structure of the display panel according to their own needs; in addition, Figure 10 , Figure 11 The electrical connection relationship between the first anode 121 and the film layer structure towards the substrate 11 side is also not shown, the user can set the electrical connection between the first anode 121 and the film layer structure according to their own needs, which is not limited in the present application; Figure 4 and Figure 9 The electrical connection between the first anode 121 and the reflection compensation structure 20 shown in the above is only one optional setting mode provided by the present application, which is not limited by the present application.

[0096] It should be noted that in the direction perpendicular to the plane where the substrate 11 is located, the depth of the first via hole 61 can be set to about 1-2 μm, so that the overall thickness of the display panel 100 can be as small as possible, realizing the user's current demand for thin display panel 100.

[0097] Figure 12 The other cross-sectional view of VV' provided by the embodiment of the present application is shown in Figure 2 , please refer to Figure 2 , Figure 4 and Figures 9-12 Optionally, the reflection compensation structure 20 includes a plate-shaped structure, a hole-shaped structure or a block-shaped structure overlapping with the via hole.

[0098] The present application also provides an optional implementation, the reflection compensation structure 20 includes a plate-shaped structure, a hole-shaped structure or a block-shaped structure overlapping with the via hole; the plate-shaped structure, specifically refers to Figure 9 The reflection compensation structure 20 is shown as a flat surface, and the plane where the reflection compensation structure 20 is located can be parallel to the plane where the substrate 11 is located; the hole-shaped structure, specifically refers to Figure 12 The reflection compensation structure 20 can include a hole-shaped structure (including a groove structure with a certain thickness) formed in the insulating layer; the block-shaped structure overlapping with the via hole, specifically refers to Figure 11 The reflection compensation structure 20 is shown as a structure block with a recess.

[0099] It should be noted that the above three ways of the reflection compensation structure 20 are only optional setting modes provided by the present application, and the present application is not limited thereto. The user can select the specific setting mode of the reflection compensation structure 20 according to actual needs.

[0100] A specific optional embodiment is provided, as shown in FIG. 1, the first anode 121 is provided with the reflection compensation structure 20 and the conductive pad 50 in the region 03 corresponding to the first anode 121. Each conductive pad 50 is a plate structure. At this time, the reflection compensation structure 20 can also be provided as a plate structure. In this way, the reflection effects of the reflection compensation structure 20 and the conductive pad 50 on the light incident to the surface thereof are equivalent, which is beneficial to improve the display uniformity of the display panel 100. Figure 9 A specific optional embodiment is provided, as shown in FIG. 1, the first anode 121 is provided with the reflection compensation structure 20 and the conductive pad 50 in the region 03 corresponding to the first anode 121. Each conductive pad 50 is a plate structure. At this time, the reflection compensation structure 20 can also be provided as a plate structure. In this way, the reflection effects of the reflection compensation structure 20 and the conductive pad 50 on the light incident to the surface thereof are equivalent, which is beneficial to improve the display uniformity of the display panel 100.

Each conductive pad 50 is a plate structure. At this time, the reflection compensation structure 20 can also be provided as a plate structure. In this way, the reflection effects of the reflection compensation structure 20 and the conductive pad 50 on the light incident to the surface thereof are equivalent, which is beneficial to improve the display uniformity of the display panel 100.

[0101] It should be noted that, Figure 12 Only the substrate 11, the first anode 121, the conductive pad 50 and the reflection compensation structure 20 included in the film layer structure of the display panel are shown. The other film layer structure not marked on the side of the first anode 121 facing the substrate 11 is some insulating layer GI. As for the structure such as transistor and capacitor that can be included between the first anode 121 and the substrate 11, it is not shown here. The user can set the transistor, capacitor and other structure included in the film layer structure of the display panel according to the actual needs. Figure 4 Figure 9 In addition, Figure 12 The electrical connection relationship between the first anode 121 and the film layer structure on the side of the substrate 11 is not shown. The user can set the electrical connection between the first anode 121 and the film layer structure according to the actual needs, and the present application does not make specific limitations thereto.​Figure 4 and Figure 9 The first anode 121 is electrically connected with the reflection compensation structure 20 as shown in the first aspect of the present application, which is only one optional setting provided by the present application, and the present application is not limited thereto.

[0102] Please refer to Figure 2 Optionally, the reflection compensation structure 20 is floating or electrically connected with the signal line.

[0103] The present application also provides an optional embodiment that when the reflection compensation structure 20 is added to the display panel 100, at least part of the reflection compensation structure 20 is not electrically connected with the structure required for transmitting electrical signals during the operation of the display panel, that is, there is redundant reflection compensation structure 20 which is not used for the display function of the display panel. At this time, the part of the reflection compensation structure 20 can be optionally set to be floating, and only used in combination with the conductive pad 50 provided in the corresponding area 03 to balance the light reflection effect of the area 03 where the first anode 121 is located, thereby improving the display uniformity of the display panel 100. In addition, the reflection compensation structure 20 can also be optionally set to be electrically connected with some fixed potential signal line, for example, the idle reflection compensation structure 20 can be set to be electrically connected with any one of the PVDD signal line, the PVEE signal line and the Vref signal line, so as to avoid the mura problem of the display panel 100.

[0104] Figure 13 as shown in the first aspect of the present application, Figure 2 is an enlarged view of the E area in the first aspect of the present application, Figure 14 as shown in the first aspect of the present application, Figure 2 is a sectional view of FF' in the first aspect of the present application, please combine Figures 4-6 , refer to Figure 2 and Figure 13 、 Figure 14 Optionally, the display panel further comprises:

[0105] The conductive pad 50 overlaps the first anode 121 in the direction perpendicular to the plane where the substrate 11 is located, and is located on the side of the first anode 121 facing the substrate 11.

[0106] The anode 12 comprises a second anode 122, which overlaps the reflection compensation structure 20 in the direction perpendicular to the plane where the substrate 11 is located, and does not overlap the conductive pad 50; the reflection compensation structure 20 is located on the side of the second anode 122 facing the substrate 11.

[0107] The display panel provided by the related art includes a part of the area 01 in which the wire-changing pads 02 are arranged in a uniform distribution or a non-uniform distribution, and an embodiment in which the wire-changing pads 02 are not arranged in the part of the area 01; in order to make the reflection effect of the side surface of the anode corresponding to the area 01 away from the substrate on the light be quite, more anodes corresponding to the area 01 are arranged to make the reflection effect of the side surface of the anode away from the substrate on the light be nearly the same, which can be realized by arranging more conductive pads 50 and / or reflection compensation structures 20 included in the area 01 to be arranged in the area 01 as uniformly as possible and / or as symmetrically as possible, so that more areas 01 make the reflection effect of the side surface of the anode corresponding to the area 01 away from the substrate on the light be nearly the same due to the arrangement of the conductive pads 50 and / or the reflection compensation structures 20, thereby improving the display uniformity of the display panel.

[0108] Therefore, the present application provides an alternative embodiment that when the display panel 100 includes the conductive pad 50, the conductive pad 50 and the first anode 121 can have an overlapping area in the direction perpendicular to the plane in which the substrate 11 is located, and the conductive pad 50 can be arranged on the side of the first anode 121 facing the substrate 11.

[0109] At this time, the present application provides an alternative embodiment that the arrangement type of the anode 12 included in the display panel 100 can include multiple types, for example, the anode 12 can include a second anode 122 in addition to the first anode 121, and the second anode 122 is different from the first anode 121 in that the second anode 122 and the reflection compensation structure 20 have an overlapping area in the direction perpendicular to the plane in which the substrate 11 is located, but the second anode 122 and the conductive pad 50 do not have an overlapping area, and the reflection compensation structure 20 can be arranged on the side of the second anode 122 facing the substrate 11.

[0110] That is, in an embodiment, the display panel 100 includes both the first anode 121 and the second anode 122, the area 03 corresponding to the first anode 121 is provided with the conductive pad 50, and the area 05 corresponding to the second anode 122 is not provided with the conductive pad 50. At this time, the area 03 corresponding to the first anode 121 can be provided with both the reflection compensation structure 20 and the conductive pad 50, or the area 03 corresponding to the first anode 121 can be provided with only the conductive pad 50, and the area 05 corresponding to the second anode 122 can be provided with only the reflection compensation structure 20. In addition, the area 05 corresponding to the second anode 122 can be provided with no reflection compensation structure 20. The user can set the number, the setting position, the area size, the shape, etc. of the reflection compensation structure 20 and the conductive pad 50 included in the area 03 corresponding to the first anode 121 and the second anode 122 according to the requirements, as long as the conductive pad 50 and / or the reflection compensation structure 20 provided in the area 03 corresponding to most or all of the anodes 12 in the display panel 100 is arranged as uniformly as possible and / or as symmetrically as possible in the area 01, so that the side surface of the corresponding anode 12 away from the substrate 11 has an area with approximately the same slight convexity or slight concavity, so that the reflection effect of the side surface of the corresponding anode 12 away from the substrate 11 on the incident light received thereby is equivalent, so that the display uniformity of the display panel 100 can be improved, and the color cast problem of the display panel in the related art can be eliminated or weakened.

[0111] It should be noted that Figure 4 Only the substrate 11, the first anode 121, and the reflection compensation structure 20 included in the film layer structure of the display panel are shown, and other film layer structures not marked toward the side of the substrate 11 of the first anode 121 are some insulating layers GI. The structures such as transistors and capacitors that can be included between the first anode 121 and the substrate 11 are not shown here, and can be set according to the embodiments shown in Figure 9 and Figure 14 or the user can set other structures included in the film layer structure of the display panel according to the requirements. In addition, Figure 4 The electrical connection relationship between the first anode 121 and the film layer structure toward the side of the substrate 11 is not shown, and the user can set the electrical connection between the first anode 121 and the film layer structure according to the requirements, which is not limited in the present application. Figure 9 and Figure 15 The electrical connection between the first anode 121 and the reflection compensation structure 20 shown in and is only one optional setting manner provided by the present application, which is not limited by the present application.

[0112] Figures 2-13Another top view of the display panel is shown in the embodiments of the present application. Please refer to Figure 15 Referring to Figure 15 Optionally, the display panel further comprises:

[0113] The green pixel G comprises the first anode 121.

[0114] The display panel 100 can comprise at least three types of pixels in the alternative embodiments of the present application, such as Figure 16 As shown, the display panel can comprise a row of red pixels RL, a row of green pixels GL and a row of blue pixels BL, such as red pixels R, green pixels G and blue pixels B. If the opening sizes of the red pixels R, the green pixels G and the blue pixels B are set to be equivalent, the luminous brightness of the green pixels G is the largest. If the regional reflection effect of the side surface of the corresponding anode 12 away from the substrate 11 in the area corresponding to the opening region of each color pixel unit is different, the display difference corresponding to the green pixels G is the most obvious. In this case, at least the corresponding anode 12 of the green pixels G is set as the first anode 121, for example, only the conductive pads 50 and / or the reflection compensation structures 20 are arranged in the area 03 corresponding to the anode 12. The anode 12 corresponding to the green pixels G is set as the first anode 121. The area where the anode 12 corresponding to the green pixels G is located comprises the conductive pads 50 and the reflection compensation structures 20. The reflection compensation structures 20 and the conductive pads 50 are combined to be arranged as uniformly as possible or symmetrically in the area corresponding to the first anode 121. The part of the area 03 where the first anode 121 of the green pixels G is located and where the reflection compensation structures 20 and the conductive pads 50 are arranged has a similar reflection effect on light. Therefore, the reflection effect of the first anode 121 on the light incident to the side surface away from the substrate 11 is more uniform. The difference in the reflection effect of the different areas of the first anode 121 on light is avoided. The color cast problem in the display area corresponding to the green pixels G is reduced or avoided. The display uniformity of the display panel 100 is improved.

[0115] Figures 1-13 Another top view of the display panel is shown in the embodiments of the present application. Please refer to Figure 16 Referring to Figure 16 In addition, as Figure 2It is shown that the application also provides an alternative embodiment that the display panel 100 can include at least three types of pixels, such as red pixels R, green pixels G, and blue pixels B. If the opening area of the red pixel R is small, the opening area of the green pixel G is the smallest, and the opening area of the blue pixel B is the largest, and there are regional differences in the reflection effect in the area corresponding to the opening area of each color pixel unit, due to the different sizes of the pixel opening areas, the display difference corresponding to the blue pixel B with the largest opening area is the most obvious, followed by the red pixel R, and the display difference corresponding to the green pixel G is the least obvious. Taking the area 03 corresponding to the anode 12 as an example, only the conductive pad 50 and / or the reflection compensation structure 20 are provided in the area 03, at this time, the anode 12 corresponding to the blue pixel B is selected to be the first anode 121, that is, the area corresponding to the anode 12 (the first anode 121) of the blue pixel B includes the conductive pad 50 and the reflection compensation structure 20, and the position of the reflection compensation structure 20 and the conductive pad 50 are combined to be as uniformly as possible or as symmetrically as possible in the area 03 corresponding to the first anode 121, so that the part of the area 03 corresponding to the first anode 121 where the reflection compensation structure 20 and the conductive pad 50 are provided has a similar reflection effect on light, thereby making the reflection effect of the first anode 121 on the light incident to the surface away from the substrate 11 more uniform, avoiding the case that different areas in the first anode 121 have a large difference in the reflection effect on light, thereby reducing or avoiding the color cast problem in the display area corresponding to the blue pixel B, and improving the display uniformity of the display panel 100.

[0116] It should be noted that when the opening area of the red pixel R is small, the opening area of the green pixel G is the smallest, and the opening area of the blue pixel B is the largest, the first anode 121 of the blue pixel B is selected to be close to the substrate 11, and the conductive pad 50 and / or the reflection compensation structure 20 are as uniformly as possible or as symmetrically as possible, which can improve the area 03 where the color cast problem is the most serious in the display panel 100, and can improve the display effect of the display panel 100 to a certain extent, but this is only one optional setting method provided by the application. Similarly, the application can select to provide the reflection compensation structure 20 and / or the conductive pad 50 in at least one or at least two or all of the areas 03 corresponding to the red pixel R, the green pixel G, and the blue pixel B, and make the reflection compensation structure 20 and / or the conductive pad 50 and / or the wire changing pad provided in the area 03 as uniformly as possible or as symmetrically as possible in the area, so that the reflection effects of a larger number of anodes 12 corresponding to the pixels on the light incident to the surface away from the substrate 11 are similar, thereby further improving the display effect of the display panel.

[0117] Please refer to Figure 13 and Figure 14 、 Figure 13 Optionally, in the direction perpendicular to the plane where the substrate 11 is located, the reflection compensation structure 20 overlapping with the same second anode 122 is symmetrically arranged in the area corresponding to the second anode 122.

[0118] The application also provides an alternative embodiment, in which, in the direction perpendicular to the plane where the substrate 11 is located, the reflection compensation structure 20 overlapping with the same second anode 122 is symmetrically arranged in the area corresponding to the second anode 122 as much as possible. Specifically, the conductive pad 50 in the area corresponding to the second anode 122 is not arranged, and only the reflection compensation structure 20 is arranged. The reflection compensation structure 20 in the area corresponding to the second anode 122 is symmetrically arranged, for example, with the symmetry axis 99, so that the reflection compensation structure 20 can be symmetrically arranged in the area corresponding to the second anode 122, so that the surface of the second anode 122 away from the substrate 11 presents a micro convex or a micro concave as much as possible due to the existence of the reflection compensation structure 20, so that the reflection effect of the surface of the second anode 122 away from the substrate 11 on the light incident thereon is more uniform, avoiding the case that different areas in the second anode 122 have a large difference in reflection effect on the light, thereby reducing or avoiding the color cast problem existing in the display area corresponding to the second anode 122, and improving the display uniformity of the display panel 100.

[0119] It should be noted that, in addition to the embodiments shown in Figures 2-7 , the reflection compensation structure 20 in the area where the second anode 122 is located can also be symmetrically arranged along the first direction and / or symmetrically arranged along the second direction, which is not limited in the application, and the user can adjust the arrangement of the corresponding reflection compensation structure 20 according to the shape and arrangement direction of the pixel opening area corresponding to the second anode 122.

[0120] Please refer to Figure 17 Optionally, in the direction perpendicular to the plane where the substrate 11 is located, the conductive pad 50 and the reflection compensation structure 20 overlapping with the same first anode 121 are symmetrically arranged in the area 03 corresponding to the first anode 121.

[0121] Optionally, when the conductive pad 50 and the reflection compensation structure 20 are correspondingly arranged in the region 03 where the first anode 121 is located, the conductive pad 50 and the reflection compensation structure 20 can be symmetrically arranged in the region 03 corresponding to the first anode 121 as much as possible in the direction perpendicular to the plane where the substrate 11 is located, so that the reflection compensation structure 20 and the conductive pad 50 can be symmetrically arranged in the region corresponding to the first anode 121 as much as possible, so that the surface of the first anode 121 away from the substrate 11 presents a micro-concave or a micro-convex as much as possible due to the existence of the reflection compensation structure 20 and the conductive pad 50, so that the reflection effect of the surface of the first anode 121 away from the substrate 11 on the light incident thereon is more uniform, avoiding the case that different regions in the first anode 121 have a large difference in reflection effect on the light, thereby reducing or avoiding the color cast problem in the display area corresponding to the first anode 121, and improving the display uniformity of the display panel 100.

[0122] It should be noted that the conductive pad 50 and the reflection compensation structure 20 in the region 03 where the first anode 121 is located can be symmetrically arranged in the first direction and / or the second direction, and the application does not make specific limitation thereon. The user can adjust the arrangement of the corresponding conductive pad 50 and the reflection compensation structure 20 according to the shape and arrangement direction of the pixel opening area corresponding to the first anode 121.

[0123] Figure 2 An enlarged view of the P region in the embodiment provided by the application is shown in FIG. 6. Figure 18 A sectional view of the KK' region in the embodiment provided by the application is shown in FIG. 7. Please refer to Figure 2 , Figure 2 , Figure 17 , Figure 18 and Figure 18 Optionally, the display panel 100 further comprises:

[0124] the conductive pad 50;

[0125] The anode 12 further comprises a third anode 123. In the direction perpendicular to the plane where the substrate 11 is located, the conductive pad 50 overlaps the third anode 123 and does not overlap the reflection compensation structure 20, and the conductive pad 50 is located on the side of the third anode 123 facing the substrate 11.

[0126] Optionally, the conductive pads 50 overlapping the same third anode 123 are symmetrically arranged in the region corresponding to the third anode 123 in the direction perpendicular to the plane where the substrate 11 is located.

[0127] It is also provided in the application that the display panel 100 includes the conductive pad 50 and the anode 12, the anode 12 can include a third anode 123, the conductive pad 50 and the third anode 123 can be overlapped in the direction perpendicular to the plane where the substrate 11 is located, and the conductive pad 50 is located on the side of the third anode 123 facing the substrate 11. Specifically, the display panel 100 includes a third anode 123, the third anode 123 is only provided with the conductive pad 50 in the area 06, and the third anode 123 is not provided with the reflection compensation structure 20, all the conductive pads 50 provided in the area 06 of the third anode 123 are uniformly distributed as much as possible or symmetrically distributed as much as possible in the area, the area corresponding to the side of the third anode 123 away from the substrate 11 has no obvious difference in the reflection effect of the light when the light incident from the side of the display panel 100, and there is no obvious color deviation problem in the display of the area corresponding to the side of the third anode 123 away from the substrate 11, so the area does not need to additionally increase the reflection compensation structure 20.

[0128] It should be noted that when the anode 12 is provided with the conductive pad 50 and / or the reflection compensation structure 20 in the area corresponding to the anode 12, the total area of the conductive pad 50 and / or the reflection compensation structure 20 exposed by the opening region in the area corresponding to the anode 12 can be selected to be equal to or less than 80% of the area of the opening region corresponding to the anode 12, so as to ensure that the conductive pad 50 and / or the reflection compensation structure 20 arranged adjacent to each other has a spacing space, avoids the problem of being connected, and avoids the problem of signal crosstalk, thereby ensuring the normal work of the display panel 100. In addition, the spacing range between the conductive pad 50 and / or the reflection compensation structure 20 arranged in the area corresponding to the anode 12 can be selected to be between 2.5 μm and 3.5 μm, which can also avoid the problem of being connected, thereby avoiding the problem of signal crosstalk and ensuring the normal work of the display panel 100.

[0129] In addition, it should be further noted that the conductive pad 50 and / or the reflection compensation structure 20 arranged in the area corresponding to the anode 12 can be provided with the same shape, and can also be provided with the same area at the same time, and the shape can be selected to be circular, elliptical, etc. The above embodiments are only the optional setting modes of the conductive pad 50 and / or the reflection compensation structure 20 provided in the application, and the application is not limited thereto. The user can adjust the shape, area, etc. of the conductive pad 50 and / or the reflection compensation structure 20 according to the actual needs.

[0130] It should be noted that, Figure 4Only the substrate 11, the first anode 121, the conductive pad 50 and the reflection compensation structure 20 included in the film layer structure of the display panel are shown, and other unmarked film layer structures on the side of the substrate 11 of the first anode 121 are some insulating layers GI. As for the structural members such as transistors and capacitors that can be included between the first anode 121 and the substrate 11, they are not shown here, and can be referred to in the embodiments shown in Figure 9 and Figure 18 The embodiments shown in the above embodiments provide the structural members such as transistors and capacitors, or the user can set other structural members included in the film layer structure of the display panel according to the user's own needs. In addition, Figure 4 The electrical connection relationship between the first anode 121 and the film layer structure members on the side of the substrate 11 is not shown either, and the user can set the electrical connection between the first anode 121 and the film layer structure members according to the user's own needs, which is not limited by the present application. Figure 9 and Figure 19 The electrical connection between the first anode 121 and the reflection compensation structure 20 shown in the above embodiments is only one optional setting provided by the present application, and the present application is not limited thereto.

[0131] Figure 19 Another top view of the display panel provided by the embodiments of the present application is shown in Figure 19 Optionally, the display panel 100 further includes a first signal wire 41 extending in a first direction, a second signal wire 42 extending in a second direction, and a first sub-wire 71, the first direction intersecting the second direction.

[0132] The first signal wire 41 and the first sub-wire 71 are electrically connected, and are used to transmit electrical signals to the second signal wire 42.

[0133] The display panel 100 further includes a second sub-wire 72 corresponding to the first sub-wire 71, and the extension direction of the second sub-wire 72 is the same as that of the first sub-wire 71.

[0134] The second sub-wire 72 is floating or electrically connected to a signal line.

[0135] This application also provides an alternative implementation in which the display panel 100 includes a first signal trace 41 extending along a first direction, a second signal trace 42 extending along a second direction, and a first sub-trace 71. The first signal trace 41 and the first sub-trace 71 can be electrically connected to transmit electrical signals to the second signal trace 42. Specifically, the second signal trace 42 can be a data signal line. This data signal line may not be directly electrically connected to the driver chip, but rather receives the data signals emitted by the driver chip through the first signal trace 41 and the first sub-trace 71. At this point, the display panel 100 can be further configured to include a second sub-line 72 corresponding to the first sub-line 71. The extension direction of the second sub-line 72 is the same as that of the first sub-line 71. The second sub-line 72 is located on the side of the first sub-line 71 away from the driver chip to which it is electrically connected. This configuration ensures that the number of lines in each area of ​​the display panel 100 is roughly the same. If the lines reflect light incident on the display panel 100 from the outside, the reflection effect of the entire display panel 100 on the outside light can be kept roughly the same, avoiding a large difference in the reflection effect of light in different areas of the display panel 100. This avoids color shift problems in the display area and improves the display uniformity of the display panel 100.

[0136] Furthermore, when the display panel 100 is provided with a second sub-trace 72, the second sub-trace 72 can be set to float or electrically connected to a signal line. When the second sub-trace 72 is set to be electrically connected to a signal line, the second sub-trace 72 can be set to be electrically connected to some fixed potential signal lines, such as setting the second sub-trace 72 to be electrically connected to any of the PVDD signal lines, PVEE signal lines, and Vref signal lines, in order to avoid the mura problem of the display panel 100.

[0137] It should also be added that, such as Figure 2 In the rightmost column of pixels, there may be an embodiment where the added reflection compensation structure 20 is located below the conductive pad 50 or the line-changing pad, rather than only being located above the conductive pad 50 or the line-changing pad. That is, as long as the line-changing pad and / or the reflection compensation structure 20 and / or the conductive pad 50 can be symmetrically arranged in the area corresponding to the anode 12, the reflection effect of the surface of the anode 12 away from the substrate 11 on the incident light is more uniform, avoiding large differences in the reflection effect of light in different areas, thereby reducing or avoiding color shift problems in the display area and improving the display uniformity of the display panel 100.

[0138] Please refer to Figure 4 and Figure 4Optionally, the display panel 100 further comprises a first metal layer and a second metal layer M2 arranged between the substrate 11 and the anode 12 in a direction perpendicular to the plane in which the substrate 11 lies, and the second metal layer M2 is arranged between the first metal layer and the anode 12.

[0139] The conductive pad 50 and the at least partial reflection compensation structure 20 are formed in the second metal layer M2.

[0140] Optionally, the display panel 100 further comprises a first metal layer and a second metal layer M2 arranged between the substrate 11 and the anode 12 in a direction perpendicular to the plane in which the substrate 11 lies, and the second metal layer M2 is arranged between the first metal layer and the anode 12.

[0141] It should be noted that, Figure 2 In the film layer structure of the display panel shown, for example, the first metal material layer L1, the capacitor metal layer L0, the second metal material layer L2, the third metal material layer L3, and the fourth metal material layer L4 can be arranged in the insulating layer GI between the substrate 11 and the anode 12, and the third metal material layer L3 can be reused as the second metal layer M2 for arranging the conductive pad 50 and / or the reflection compensation structure 20. The first metal layer can be reused as any one of the first metal material layer L1, the capacitor metal layer L0, and the second metal material layer L2. The conductive pad 50 and the at least partial reflection compensation structure 20 are formed in the second metal layer M2, which means that the conductive pad 50 and the at least partial reflection compensation structure 20 are arranged closer to the anode 12, so that the influence of the conductive pad 50 and / or the reflection compensation structure 20 on the flatness of the side of the anode 12 away from the substrate 11 is more obvious, and the reflection effects of the side of the anode 12 away from the substrate 11 in as many display panels as possible are more similar to the incident light, thereby avoiding a large difference in the reflection effects of different display areas on the light and ensuring the display uniformity of the display panel 100.

[0142] Furthermore, an alternative embodiment is provided, when the substrate 11, the first metal layer, the second metal layer M2 and the anode 12 including the above-mentioned structure are included in the display panel 100, the wire changing pad and / or the conductive pad and / or the reflection compensation structure to be arranged in the corresponding area of the anode 12 can be recessed to the side of the substrate 11 of the second metal layer M2. Compared with the wire changing pad and / or the conductive pad and / or the reflection compensation structure formed on the first metal layer and further away from the side of the substrate 11, the wire changing pad and / or the conductive pad and / or the reflection compensation structure formed by recessing the second metal layer M2 to the side of the substrate 11 is more likely to cause the anode 12 in the corresponding area to be slightly recessed away from the surface of the side of the substrate 11. Therefore, arranging the wire changing pad and / or the conductive pad 50 and / or the reflection compensation structure 20 on the second metal layer M2 can better improve the color cast problem of the display panel 100 and further improve the display uniformity of the display panel 100.

[0143] Please refer to Figure 4 and Figure 20 Optionally, the display panel 100 further includes a pixel definition layer PDL, and the pixel definition layer PDL is located on the side of the anode 12 away from the second metal layer M2.

[0144] The display panel 100 further includes a plurality of pixel opening regions 30, and the pixel opening regions 30 penetrate the pixel definition layer PDL and expose the anode 12.

[0145] The display panel 100 further includes a pixel definition layer PDL, and the pixel definition layer PDL is located on the side of the anode 12 away from the second metal layer M2. The pixel opening regions 30 in the display panel 100 can be manufactured by penetrating the pixel definition layer PDL and exposing the anode 12. In the pixel opening regions 30, the side of the anode 12 away from the substrate 11 can be further provided with a light-emitting layer 125 and a cathode 126 to manufacture a light-emitting element.

[0146] Figures 1-19 The display device provided by the embodiment of the present application is shown in a schematic diagram.

The display device 200 provided by the present application can be any product and component with display function, such as a mobile phone, a tablet computer, a television, a display, a notebook computer, a navigator, etc.

[0148] It can be known by the above embodiments that the display panel and the display device provided by the application at least achieve the following beneficial effects:

[0149] The application sets the reflection compensation structure in the display panel to balance the reflection effect of the area where the first anode is on the incident light from the outside, so that the reflection effect of each area where the first anode is on the incident light from the outside is more uniform, avoiding the case that the reflection effect of light by different areas in the first anode is greatly different, thereby reducing or avoiding the color cast problem existing in the display area corresponding to the first anode, and improving the display uniformity of the display panel.
