Technical Field

[0001] This application relates to the field of display panels, and more particularly to a display panel and display device. Background Technology

[0002] With the advancement of technology, the application scenarios of display panels are becoming increasingly widespread, and borderless display panels have emerged as a result. However, due to manufacturing limitations, there is a difference in display brightness between the edge and center areas of borderless display panels, resulting in uneven display between the edge and center areas. Summary of the Invention

[0003] In view of this, embodiments of this application provide a display panel and a display device to improve the uniformity of the overall display of the display panel.

Along a first direction, the distance between adjacent first pixel circuits is less than the distance between adjacent second pixel circuits, and the first direction is parallel to the plane of the display panel.

[0005] The display panel includes: a first metal structure and an anti-reflective structure.

[0006] In the first display area, at least a portion of the first metal structure does not overlap with the anti-reflective structure along a direction perpendicular to the plane of the display panel. In the second display area, the anti-reflective structure covers the first metal structure along a direction perpendicular to the plane of the display panel.

[0007] In one possible implementation of the first aspect, the first display area includes a plurality of first light-emitting devices. The second display area includes a plurality of second light-emitting devices. The color of light emitted by the first light-emitting devices is the same as the color of light emitted by the second light-emitting devices. In the first display area, the distance between the anti-reflective structure and the first light-emitting devices along a first direction is a first distance. In the second display area, the distance between the anti-reflective structure and the second light-emitting devices along the first direction is a second distance. The first distance is greater than the second distance.

[0008] In one possible implementation of the first aspect, the first display area further includes a plurality of third light-emitting devices, wherein the color of light emitted by the first light-emitting devices is different from the color of light emitted by the third light-emitting devices. In the first display area, the distance between the anti-reflective structure and the third light-emitting devices along a first direction is a third distance. The first distance and the third distance are different.

[0009] In one possible implementation of the first aspect, the first light-emitting device emits light of red or blue color, and the third light-emitting device emits light of green color. The first distance is greater than the third distance.

[0010] In one possible implementation of the first aspect, the first display area includes a first sub-region and a second sub-region, with a first pixel circuit located within the first sub-region. The second sub-region includes a driving circuit. The first distance includes a first sub-distance and a second sub-distance. Within the first sub-region, the distance between the anti-reflective structure and the first light-emitting device along a first direction is the first sub-distance. Within the second sub-region, the distance between the anti-reflective structure and the first light-emitting device along the first direction is the second sub-distance. The first sub-distance and the second sub-distance are different.

[0011] In one possible implementation of the first aspect, the first sub-distance is less than the second sub-distance.

[0012] In one possible implementation of the first aspect, the first sub-region is located between the second sub-region and the second display region.

[0013] In one possible implementation of the first aspect, the second sub-region is located between the first sub-region and the second display region.

[0014] In one possible implementation of the first aspect, the first display area further includes a plurality of third light-emitting devices, wherein the color of light emitted by the first light-emitting devices is different from the color of light emitted by the third light-emitting devices. In the first display area, the distance between the anti-reflective structure and the third light-emitting devices along a first direction is a third distance. The first distance and the third distance are equal.

[0015] In one possible implementation of the first aspect, the display panel further includes a non-display area and a driving circuit, wherein the non-display area is located on the side of the display area facing the bonding pin, and the driving circuit is located within the non-display area.

[0017] The display panel provided in this application embodiment increases the overall brightness of the first display area by exposing at least a portion of the first metal structure within the first display area and utilizing the reflective effect of the first metal structure on the light-emitting device. Simultaneously, it reduces the reflection of the light-emitting device in the second display area through an anti-reflective structure, thereby balancing the display brightness of the first and second display areas. Therefore, the display panel provided in this application embodiment exhibits good uniformity in display brightness. Attached Figure Description

Detailed Implementation

[0020] To better understand the technical solution of this application, the embodiments of this application will be described in detail below with reference to the accompanying drawings.

[0021] It should be understood that the described embodiments are merely some, not all, of the embodiments in this application. All other embodiments obtained by those skilled in the art based on the embodiments in this application without inventive effort are within the scope of protection of this application.

[0022] The terminology used in the embodiments of this application is for the purpose of describing particular embodiments only and is not intended to be limiting of this application. The singular forms “a,” “the,” and “the” used in the embodiments of this application and the appended claims are also intended to include the plural forms unless the context clearly indicates otherwise.

[0023] It should be understood that the term "and / or" used in this article is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A existing alone, A and B existing simultaneously, or B existing alone. Additionally, the character " / " in this article generally indicates that the preceding and following related objects have an "or" relationship.

[0024] The inventors discovered that the difference in display quality between the edge and center areas of a borderless display panel is due to the following: To achieve a borderless display, the driving circuitry of the display panel needs to be placed within the display area. Therefore, the pixel circuitry on the sides of the display panel needs to be compressed to make room for the driving circuitry. This results in a higher metal density at the edge of the display panel compared to the center area.

[0025] To prevent the metal from reflecting ambient light, a black matrix (BM) is used to shield the metal. The metal density at the edges of the display panel is greater than that in the center, resulting in a higher BM density at the edges. In other words, the BM area at the edges is larger than that at the center. Since the BM absorbs light emitted by the LEDs, this means that, for the same area, more light emitted by the LEDs at the edges will be absorbed by the BM compared to the center. This leads to lower brightness at the edges compared to the center, resulting in uneven display brightness.

[0026] To address the aforementioned problems, this application provides a display panel and display device to solve these problems and improve the uniformity of display panel brightness. The inventive concept of this application can be summarized as follows: exposing at least a portion of a first metal structure in a first display area that can be illuminated by light emitted from a light-emitting device, thereby enabling the first metal structure to emit light emitted from the light-emitting device out of the display panel, increasing display brightness to compensate for the brightness difference between the first and second display areas, thus achieving the goal of improving the uniformity of display panel brightness.

[0027] like Figure 1As shown, this application embodiment provides a display panel 100, including a display area AA. For example, in one possible implementation, the display panel 100 is a borderless display panel 100. The borderless designation means that it is partially borderless, with at least one side used for mounting a driver chip or wiring interface, etc. Therefore, the display panel 100 has at least one side with a border (i.e., a non-display area). Taking a rectangular borderless display panel 100 as an example, three sides are borderless, and one side has a border. For example, the first side and the second side are opposite each other and both are borderless, while the third side has a border for mounting a driver chip or setting up a wiring interface. In one possible implementation, the first side can be the left side, and the second border can be the right side.

[0028] Combination Figure 1 and Figure 2 As shown, the display area AA includes a first display area A1 and a second display area A2. The first display area A1 includes multiple first pixel circuits 111, and the second display area A2 includes multiple second pixel circuits 112. Along the first direction X, the distance between adjacent first pixel circuits 111 is less than the distance between adjacent second pixel circuits 112. The first direction X is parallel to the plane where the display panel 100 is located. Therefore, the first display area A1 can be a pixel circuit compression area, and the second display area A2 is a conventional pixel circuit area. The pixel circuit compression area and the conventional pixel circuit area are relative concepts; the area with a larger distance between pixel circuits 110 is called the conventional pixel circuit area, while the area with a smaller distance between pixel circuits 110 relative to the conventional pixel circuit area is called the pixel circuit compression area. In one possible implementation, along the first direction X, the first area is located on both sides of the second area. For example, the first direction X can be the direction from the first side of the display panel 100 to the second side; then, a portion of the first area is located between the second area and the first side, and a portion of the first area is located between the second area and the second side.

[0029] The display panel 100 includes a first metal structure 120 and an anti-reflective structure 130. At least a portion of the first metal structure 120 is used to reflect light emitted by a light-emitting device. The first metal structure 120 can be directly or indirectly illuminated by light emitted by the light-emitting device, wherein direct illumination means that light emitted by the light-emitting device directly illuminates the metal structure, and indirect illumination means that light emitted by the light-emitting device is reflected by other structures and then illuminates the metal structure. The first metal structure 120 is defined as a structure that, along a direction perpendicular to the display panel, does not overlap with the anti-reflective structure 130 in a first display area but overlaps with the anti-reflective structure in a second display area, and can be directly or indirectly illuminated by light emitted by the light-emitting device. In one possible implementation, the first metal structure 120 may be part of a pixel circuit 110, a pixel electrode, a signal line, or a shift register circuit. For example, the first metal structure 120 is located in a first metal layer and / or a second metal layer, wherein the first metal layer is the metal layer in the display panel 100 closest to the light-emitting device, and the second metal layer is the metal layer closest to the first metal layer and located on the side of the first metal layer opposite to the light-emitting device. The anti-reflective structure 130 is used to block some of the metal wiring in the display panel 100, such as pixel circuits 110, signal lines, shift register circuits, etc., to reduce the adverse effects of ambient light on the display effect.

[0030] In the first display area A1, at least a portion of the first metal structure 120 does not overlap with the anti-reflective structure 130 along the direction Z perpendicular to the plane of the display panel 100. This non-overlapping nature of the first metal structure 120 within the first display area A1 means that at least a portion of the first metal structure 120 can be exposed outside the anti-reflective structure 130. Therefore, the first metal structure 120 can emit light from the surface of the first metal structure 120 illuminated by the light-emitting device, thereby increasing the amount of light emitted and improving the display brightness.

[0031] Within the second display area A2, an anti-reflective structure 130 covers the first metal structure 120 along a direction perpendicular to the plane of the display panel 100. This anti-reflective structure 130 covering the first metal structure 120 within the second display area A2 serves two purposes: firstly, it reduces the negative impact of ambient light reflection on the display effect within the second area; secondly, it limits the emission of light from the light-emitting devices that strikes the surface of the first metal structure 120. This balances the total amount of light emitted by the light-emitting devices in the first and second areas, reducing the difference in display brightness between the first display area A1 and the second display area A2, and improving the uniformity of the display brightness of the display panel 100.

[0032] In this embodiment, by exposing at least a portion of the first metal structure 120 within the first display area A1, the reflective effect of the first metal structure 120 on the light-emitting device increases the overall brightness, thereby improving the display brightness within the first display area A1. Simultaneously, the anti-reflective structure 130 reduces the reflection amount of the light-emitting device within the second display area A2, thus balancing the display brightness of the first display area A1 and the second display area A2. Therefore, the display panel 100 provided in this embodiment exhibits good uniformity in display brightness.

[0033] In one embodiment of this application, the first display area A1 includes a plurality of first light-emitting devices 101. The second display area A2 includes a plurality of second light-emitting devices 102. The color of the light emitted by the first light-emitting devices 101 is the same as the color of the light emitted by the second light-emitting devices 102. The shapes and areas of the first light-emitting devices 101 and the second light-emitting devices 102 are equal. In one manufacturing process, when preparing the anti-reflective structure 130, a full-surface structure is first formed, and then holes are made in the full-surface structure to avoid the light-emitting devices (including the first light-emitting devices 101 and the second light-emitting devices 102), thus obtaining a reflective structure. Therefore, the emitting structure surrounds the light-emitting devices and maintains a distance from them.

[0034] like Figure 3 As shown, in the first display area A1, the distance between the anti-reflective structure 130 and the first light-emitting device 101 along the first direction X is a first distance D. In the second display area A2, the distance between the anti-reflective structure 130 and the second light-emitting device 102 along the first direction X is a second distance d. The first distance D is greater than the second distance d.

[0035] In this embodiment, the openings of the anti-reflective structure 130 in the first display area A1 and the second reflective area are different during the manufacturing process, and the opening in the first display area A1 is larger than the opening in the second reflective area. This allows at least a portion of the first metal structure 120 to be exposed in the first display area, while the first metal structure 120 does not need to be exposed in the second display area. Exposing at least a portion of the first metal structure 120 increases the total amount of display light emitted in the first display area A1 (i.e., the amount of light directly emitted by the light-emitting device + the amount of display light reflected by the first metal structure 120), thereby improving the display brightness in the first display area A1.

[0036] like Figure 3 As shown in one embodiment of this application, the first display area A1 further includes a plurality of third light-emitting devices 103, wherein the color of the light emitted by the first light-emitting device 101 is different from the color of the light emitted by the third light-emitting device 103. In the first display area A1, the distance between the anti-reflective structure 130 and the third light-emitting device 103 along the first direction X is a third distance H. The first distance D is equal to the third distance H.

[0037] In this implementation, the distance between the light-emitting devices of different colors and the anti-reflective structure 130 is the same, which means that the clearance holes opened for the light-emitting devices of different colors in the fabrication process of the anti-reflective structure 130 are consistent. This consistent hole design helps to reduce the design difficulty and the difficulty of process implementation, thereby helping to reduce production costs.

[0038] In one possible implementation, the first display area A1 further includes a plurality of third light-emitting devices 103, wherein the color of the light emitted by the first light-emitting device 101 is different from the color of the light emitted by the third light-emitting device 103. In the first display area A1, the distance between the anti-reflective structure 130 and the third light-emitting device 103 along a first direction X is a third distance. The first distance and the third distance are different.

[0039] In this implementation, the distances between the light-emitting devices of different colors and their corresponding anti-reflective structures 130 are different. This means that the exposed areas of the first metal structure 120 corresponding to the light-emitting devices of different colors are different. Consequently, the areas of light emitted by the light-emitting devices of different colors that are received and reflected by the corresponding first metal structure 120 are different, resulting in different total amounts of display light emitted by the light-emitting devices of different colors. This can compensate for the differences in light emission effects of different light-emitting devices within the first display area A1.

[0040] like Figure 4 As shown, in one possible implementation, the first light-emitting device 101 emits red or blue light, and the third light-emitting device 103 emits green light. The first distance D is greater than the third distance H. Taking the Micro LED (Micro Light-Emitting Diode) display panel 100 as an example, the green light-emitting device has the best light emission effect, while the red or blue light-emitting devices have poor light emission effects. Therefore, the first distance is greater than the third distance, resulting in greater compensation for the red or blue light-emitting devices compared to the green light-emitting device. That is, more reflected light can be used to compensate for the brightness of the red or blue light-emitting devices.

[0041] like Figure 5As shown, in one possible implementation, the first display area A1 includes a first sub-area A11 and a second sub-area A12, with the first pixel circuit 111 located within the first sub-area A11. The second sub-area A12 includes a driving circuit; the driving circuit refers to a circuit used to drive the pixel circuit 110, such as a shift register circuit. Therefore, the first sub-area A11 is a compressed pixel circuit 110 area, and the second sub-area A12 is a driving circuit area. The first distance includes a first sub-distance D1 and a second sub-distance D2. Within the first sub-area, the distance between the anti-reflective structure 130 and the first light-emitting device 101 along the first direction X is the first sub-distance D1. Within the second sub-area, the distance between the anti-reflective structure 130 and the first light-emitting device 101 along the first direction X is the second sub-distance D2. The first sub-distance D1 and the second sub-distance D2 are equal.

[0042] In this implementation, the first sub-distance D1 is equal to the second sub-distance D2, which means that the anti-reflection structure 130 of the same color light-emitting device in the driving circuit area and the compression pixel circuit 110 area has the same opening size during the fabrication process, which helps to reduce the design difficulty and the process implementation difficulty, thereby helping to reduce the production cost.

[0043] In one possible implementation, the first display area A1 includes a first sub-area A11 and a second sub-area A12, with the first pixel circuit 111 located within the first sub-area A11. The second sub-area A12 includes a driving circuit; the driving circuit refers to a circuit used to drive the pixel circuit 110, such as a shift register circuit. Therefore, the first sub-area A11 is a compressed pixel circuit 110 area, and the second sub-area A12 is a driving circuit area. The first sub-area A11 includes a plurality of first light-emitting devices and a third light-emitting device, the first light-emitting devices and the third light-emitting devices having different colors. Within the first sub-area, the distance between the anti-reflective structure 130 and the first light-emitting device 101 along the first direction X is a first sub-distance D1, and the distance between the anti-reflective structure 130 and the third light-emitting device 103 along the first direction X is a third sub-distance H1.

[0044] The second sub-region A12 includes multiple first light-emitting devices 101 and third light-emitting devices 103, with the first and third light-emitting devices having different colors. Within the second sub-region, the distance between the anti-reflective structure 130 and the first light-emitting device 101 along the first direction X is the second sub-distance D2, and the distance between the anti-reflective structure 130 and the third light-emitting device 103 along the first direction X is the fourth sub-distance H2. The first sub-distance D1 is equal to the second sub-distance D2, and the third sub-distance H1 is equal to the fourth sub-distance H2.

[0045] In this implementation, the first sub-distance D1 is equal to the second sub-distance D2, and the third sub-distance H1 is equal to the fourth sub-distance H2. This means that the anti-reflection structure 130 of the same color light-emitting device in the driving circuit area and the compressed pixel circuit 110 area has the same opening size during the fabrication process, which helps to reduce the design difficulty and the process implementation difficulty, thereby helping to reduce the production cost.

[0046] In one possible implementation, the first sub-distance D1, the second sub-distance D2, the third sub-distance H1, and the fourth sub-distance H2 are all equal. Therefore, the anti-reflection structures 130 for the same and different color light-emitting devices in the driving circuit area and the compression pixel circuit 110 area have the same opening size during the fabrication process, which helps to reduce the design difficulty and the difficulty of process implementation, thereby helping to reduce production costs.

[0047] In one possible implementation, the first sub-distance D1 is equal to the second sub-distance D2, and the third sub-distance H1 is equal to the fourth sub-distance H2, while the first sub-distance D1 and the third sub-distance H1 are not equal. For example, the first light-emitting device 101 emits light of red or blue color, and the third light-emitting device 103 emits light of green color. The first sub-distance D1 is greater than the third sub-distance H1.

[0048] In one possible implementation, the first display area A1 includes a first sub-area A11 and a second sub-area A12, with the first pixel circuit 111 located within the first sub-area A11. The second sub-area A12 includes a driving circuit; the driving circuit refers to a circuit used to drive the pixel circuit 110, such as a shift register circuit. Therefore, the first sub-area A11 is a compressed pixel circuit 110 area, and the second sub-area A12 is a driving circuit area. The first sub-area A11 includes multiple first light-emitting devices and third light-emitting devices, with the first and third light-emitting devices having different colors. Within the first sub-area, the distance between the anti-reflective structure 130 and the first light-emitting device 101 along the first direction X is a first sub-distance D1, and the distance between the anti-reflective structure 130 and the third light-emitting device 103 along the first direction X is a third sub-distance H1. The first sub-distance D1 and the third sub-distance H1 are not equal. For example, the first light-emitting device 101 emits red or blue light, and the third light-emitting device 103 emits green light. The first sub-distance D1 is greater than the third sub-distance H1.

[0049] And / or, The second sub-region A12 includes multiple first light-emitting devices 101 and third light-emitting devices 103, with the first and third light-emitting devices having different colors. Within the second sub-region, the distance between the anti-reflective structure 130 and the first light-emitting device 101 along the first direction X is the second sub-distance D2, and the distance between the anti-reflective structure 130 and the third light-emitting device 103 along the first direction X is the fourth sub-distance H2. The second sub-distance D2 and the fourth sub-distance H2 are not equal. For example, the first light-emitting device 101 emits red or blue light, while the third light-emitting device 103 emits green light. The second sub-distance D2 is greater than the fourth sub-distance H2.

[0050] like Figure 6 As shown, in one possible implementation, the first display area A1 includes a first sub-area A11 and a second sub-area A12, with the first pixel circuit located within the first sub-area A11. The second sub-area A12 includes a driving circuit; the driving circuit refers to a circuit used to drive the pixel circuit, such as a shift register circuit. Therefore, the first sub-area A11 is a compressed pixel circuit area, and the second sub-area A12 is a driving circuit area. The first distance includes a first sub-distance D1 and a second sub-distance D2. The first sub-area A11 includes a plurality of first light-emitting devices 101. Within the first sub-area A11, the distance between the anti-reflective structure 130 and the first light-emitting device 101 along the first direction X is the first sub-distance D1. The second sub-area A12 includes a plurality of first light-emitting devices 101. Within the second sub-area A12, the distance between the anti-reflective structure 130 and the first light-emitting device 101 along the first direction X is the second sub-distance D2. The first sub-distance D1 and the second sub-distance D2 are different.

[0051] In this implementation, the first sub-distance D1 is not equal to the second sub-distance D2, which means that the compensation strength for reflected light from the same color light-emitting device is different in the driving circuit area and the compression pixel circuit 110 area, thus effectively compensating for the difference in display brightness between the driving circuit area and the compression pixel circuit 110 area.

[0052] For example, such as Figure 6 As shown, in one possible implementation, the first sub-distance D1 is smaller than the second sub-distance D2. The inventors have discovered that, compared to the conventional pixel circuit area, the display brightness of the compressed pixel circuit 110 area is dimmer, and the display brightness of the driving circuit area is the dimmer. Therefore, the fact that the first sub-distance D1 is smaller than the second sub-distance D2 means that within the second sub-region A12, the first metal structure 120 has a larger exposed area, allowing the first metal structure 120 within the second sub-region A12 to reflect more light and compensate for the increased display brightness.

[0053] like Figure 7As shown, in one possible implementation, the first sub-region A11 is located between the second sub-region A12 and the second display area A2. In this implementation, the driving circuit area is located between the conventional pixel circuit area and the compression circuit area, and can simultaneously and evenly output scanning signals to both sides (the compression pixel circuit area 110 and the conventional pixel circuit area), avoiding large voltage drop and uneven signal delay at the far end pixel driven by unilateral driving.

[0054] like Figure 8 As shown, in one possible implementation, the second sub-region A12 is located between the first sub-region A11 and the second display area A2. The driving circuit is arranged on the outermost side, and the compression pixel circuit 110 in the compression pixel circuit area serves as a transition area, allowing the display area AA to be closer to the panel edge, achieving a borderless display. Furthermore, the compression pixel circuit 110 forms a buffer isolation layer between the driving circuit and the conventional pixel circuit 110 in the conventional pixel circuit area, reducing the interference of the high-frequency, high-current signals of the driving circuit on the normal display pixels, thus improving display stability and image quality.

[0055] In one embodiment of this application, the light-emitting device is surrounded by an anti-reflective structure 130, which includes sidewalls facing the light-emitting device. The center of the light-emitting device is at the same minimum distance from each sidewall of the anti-reflective structure 130; or, the center of the light-emitting device coincides with the center of the pattern formed by the sidewalls of the anti-reflective structure 130. The fact that the center of the light-emitting device is at the same minimum distance from each sidewall of the anti-reflective structure 130 ensures that the reflection effect of the first metal structure 120 along the periphery of the light-emitting device is nearly uniform, thereby improving the uniformity of the display effect.

[0056] As shown in Figure 9, in one embodiment of this application, the display panel 100 further includes a non-display area NA and a driving circuit. The non-display area NA is located on the side of the display area AA facing the bonding pin, and the driving circuit is located within the non-display area NA.

[0057] In this embodiment, the driving circuit is located outside the display area AA and in the lower border area, which can save space in the display area and help reduce the difficulty of borderless display.

[0058] like Figure 10 As shown, this application embodiment also provides a display device 200, including the display panel 100 provided in the foregoing embodiment.

[0059] The display device 200 provided in this application embodiment can be a monitor, television, tablet computer, smart wearable, vehicle display, public display screen, etc. The display device provided in this application embodiment increases the overall brightness of the first display area A1 by exposing at least a portion of the first metal structure 120 within the first display area A1 and utilizing the reflective effect of the first metal structure 120 on the light-emitting device. Simultaneously, the anti-reflective structure 130 reduces the reflection amount of the light-emitting device in the second display area A2, thereby balancing the display brightness of the first display area A1 and the second display area A2. Therefore, the display panel 100 provided in this application embodiment has good uniformity in display brightness.
