Description

Technical Field

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

[0002] The display panel includes multiple pixels, and each pixel can include subpixels of different colors. In related technologies, due to factors such as the arrangement of subpixels and the light-emitting area of ​​the subpixels, color shift issues occur near the edge of the display panel when displaying a white image. For example, parts of the display panel's edge may appear reddish or greenish, affecting the display effect. Summary of the Invention

[0003] In view of this, this application provides a display panel and a display device to help solve the above problems.

[0004] In a first aspect, this application provides a display panel, including a display area and a border area, wherein the border area surrounds the display area; the display area includes a first sub-area and a second sub-area, wherein the first sub-area is adjacent to the border area in a first direction, and the second sub-area is adjacent to the first sub-area in a first direction and is located on the side of the first sub-area away from the border area in the first direction.

[0005] The display area includes multiple pixels, among which a first sub-pixel is included; at least some of the first sub-pixels located in the first sub-area have a brightness that is less than that of the first sub-pixels in the second sub-area.

[0006] Secondly, this application provides a display device, including a display panel as provided in the first aspect.

[0007] In this embodiment, the luminance of some first sub-pixels located in the first sub-region is set to be less than that of the first sub-pixels in the second sub-region. This helps to reduce the total luminous intensity emitted by the first sub-pixels located in the first sub-region, thereby reducing the luminous intensity of the first sub-pixels near the border area. This reduces the color shift caused by multiple first sub-pixels near the border area and improves the white screen display effect of the display panel. Attached Figure Description

These terms are only used to distinguish sub-regions, sub-pixels, directions, etc., from each other. For example, without departing from the scope of the embodiments of this application, a first sub-region may also be referred to as a second sub-region, and similarly, a second sub-region may also be referred to as a first sub-region. Through meticulous and in-depth research, the applicant of this case provides a solution to the problems existing in the prior art.

[0031] Figure 1 This is a plan view of a display panel provided in an embodiment of this application.

[0032] This application embodiment provides a display panel 100, such as Figure 1As shown, the display area includes a display area 10 and a border area 20, with the border area 20 surrounding the display area 10. The display area 10 includes a first sub-area 101 and a second sub-area 102. The first sub-area 101 is adjacent to the border area 20 in a first direction X1, and the second sub-area 102 is adjacent to the first sub-area 101 in the first direction X1, with the second sub-area 102 located on the side of the first sub-area 101 away from the border area 20 in the first direction X1. Along the first direction X1, there are at least two first sub-areas 101, and both first sub-areas 101 are adjacent to the border area 20 in the first direction X1. The second sub-area 102 is located between the two first sub-areas 101 in the first direction X1.

[0033] In related technologies, the first sub-region of the display panel is adjacent to the border area, and no other display area exists between the first sub-region and the border area. Since the sub-pixels within the first sub-region are arranged in the same way—that is, multiple first sub-pixels of the same color emit light near the border area within the first sub-region—and there is no other color of light to harmonize the first sub-pixels and the border area, the light emitted by the multiple first sub-pixels near the border area appears more concentrated and the color more prominent. For example, each pixel includes a first sub-pixel, a second sub-pixel, and a third sub-pixel. The first sub-pixel emits red light, the second sub-pixel emits green light, and the third sub-pixel emits blue light. Since the human eye is more sensitive to red and green light, when the first sub-region near the border area consists entirely of first sub-pixels, the area near the border area appears reddish in a white display. Alternatively, when the first sub-region near the border area consists entirely of second sub-pixels, the area near the border area appears greenish in a white display. Both of these color shifts reduce the display effect of the display panel.

[0034] The display area 10 includes multiple pixels M, and each pixel M includes a first sub-pixel M1. As is known from the aforementioned related technologies, the human eye is highly sensitive to red and green light, and when displaying a white screen, the portion of the display panel 100 near the border area A20 is prone to a reddish or greenish color shift. Therefore, in this application, the first sub-pixel M1 is described as a red sub-pixel. In some other embodiments, the first sub-pixel M1 may also be other colors.

[0035] The sub-pixel arrangement of pixels M1 in the display panel 100 is as follows: Figure 1 The following example will be used for illustration, specifically the first sub-region 101 of the first sub-region 101 located near the top of the display panel 100 in the first direction X1. Figure 1As shown, in a pixel M1, the first sub-pixel M1 is relatively close to a portion of the border area 20 in the first direction X1. The first sub-pixel M1 located within the first sub-region 102 has a noticeable color shift effect on the display of the white screen. Optionally, the sub-pixel arrangement of the multiple pixels M in the second sub-region 102 is the same as that of the multiple pixels M in the first sub-region 102. However, the second sub-region 102 is farther from the border area 20 in the first direction X1, so the first sub-pixel M1 in the second sub-region 102 has almost no impact on the display of the white screen.

[0036] The brightness of at least some of the first sub-pixels M1 located in the first sub-region 101 is less than the brightness of the first sub-pixels M1 located in the second sub-region 102. Therefore, the luminous intensity of the portion of the first sub-pixels M1 with decreased brightness located in the first sub-region 101 decreases. In general, the total luminous intensity of the multiple first sub-pixels M1 located in the first sub-region 101 decreases, resulting in a decrease in the visibility of the light emitted by the multiple first sub-pixels M1 near the border region 20.

[0037] In this embodiment, the luminance of some first sub-pixels M1 located in the first sub-region 101 is set to be less than that of the first sub-pixels M1 in the second sub-region 102. This helps to reduce the total luminous intensity emitted by the first sub-pixels M1 located in the first sub-region 101, thereby reducing the luminous intensity of the first sub-pixels M1 near the border area 20. This reduces the color shift caused by multiple first sub-pixels M1 near the border area 20 and improves the white screen display effect of the display panel 100.

[0038] Figure 2 An embodiment provided in this application Figure 1 A schematic diagram of the central region E1.

[0039] In one embodiment of this application, combined with Figure 1 , Figure 2 As shown, among the plurality of first sub-pixels M1 located within the first sub-region 101, there is a first type of first sub-pixel M1A, and the first type of first sub-pixel M1A is adjacent to the border region 20 in the first direction X1. In some technical solutions, some of the first sub-pixels M1 located in the first sub-region 101 can be adaptively selected as the first type of first sub-pixel M1A according to the degree of influence of the plurality of first sub-pixels M1 within the first sub-region 101 on color shift, or all the first sub-pixels M1 located in the first sub-region 101 are the first type of first sub-pixel M1A.

[0040] Specifically, if the light-emitting area of ​​the first sub-pixel M1A of the first type is smaller than the light-emitting area of ​​the first sub-pixel M1 located in the second sub-region 102, then when the light-emitting driving current received by the first sub-pixel M1A of the first type and the first sub-pixel M1 located in the second sub-region 102 are equal, the light emission amount of the first sub-pixel M1A of the first type is equal to the light emission amount of the first sub-pixel M1 located in the second sub-region 102. Optionally, among the plurality of first sub-pixels M1 located in the first sub-region 101, the light-emitting areas of the first sub-pixels M1 other than the first sub-pixel M1A of the first type are equal to the light emission areas of the plurality of first sub-pixels M1 located in the second sub-region 102.

[0041] In this embodiment, the light-emitting area of ​​the first sub-pixel M1A in the first sub-region 101 is set to be smaller than the light-emitting area of ​​the first sub-pixel M1 in the second sub-region 102. This is beneficial to reduce the total light emission of the first sub-pixel M1 in the first sub-region 101, thereby reducing the total light emission brightness of the multiple sub-pixels M1 in the first sub-region 101 and reducing the color shift effect of the first sub-pixel M1 in the first sub-region 101 on the border area 20.

[0042] In one embodiment of this application, reference continues to be made to... Figure 2 As shown, the shape of the first sub-pixel M1A of the first type located in the first sub-region 101 is the same as the shape of the first sub-pixel M1 located in the second sub-region 102.

[0043] In this embodiment, the first type of first sub-pixel M1A located in the first sub-region 101 and the first sub-pixel M1 located in the second sub-region 102 have different areas but the same shape. The light-emitting area of ​​the first type of first sub-pixel M1A located in the first sub-region 101 is smaller than the light-emitting area of ​​the first sub-pixel M1 located in the second sub-region 102. This helps to reduce the complexity of fabricating the first type of first sub-pixel M1A, thereby reducing the cost of fabricating the first type of first sub-pixel M1A and improving the fabrication efficiency of the first type of first sub-pixel M1A.

[0044] Figure 3 Another embodiment provided in this application Figure 1 A plan view of the central region E1. Figure 4 Another embodiment provided in this application Figure 1 A schematic diagram of the central region E1.

[0045] In one embodiment of this application, such as Figure 3 , Figure 4 As shown, the shape of the first sub-pixel M1A located in the first sub-region 101 is different from the shape of the first sub-pixel MI located in the second sub-region 102. In the embodiments of this application, as... Figure 3 , Figure 4As shown, the example is taken where the shape of the first sub-pixel M1 located in the second sub-region 102, excluding the first sub-pixel M1 of the first type, is the same as the shape of the first sub-pixel M1 located in the second sub-region 102.

[0046] Optionally, such as Figure 3 As shown, the shape of the first sub-pixel M1A in the first sub-region 101 is convex, and the shape of the first sub-pixel M1 in the second sub-region 102 is rectangular. Optionally, as... Figure 4 As shown, the shape of the first sub-pixel M1A in the first sub-region 101 is a triangle, and the shape of the first sub-pixel M1 in the second sub-region 102 is a rectangle.

[0047] In this embodiment, the first type of first sub-pixel M1A located in the first sub-region 101 and the first sub-pixel M1 located in the second sub-region 102 have different areas and shapes. This is beneficial for adaptively selecting the shape of the first type of first sub-pixel M1A according to the degree of color shift near the border area 20 in the display panel 100. In some technical solutions, the light emission amount at different positions of a certain first type of first sub-pixel M1A can be adjusted by using the different shapes of the first type of first sub-pixel M1A, thereby more accurately adjusting the total luminous brightness of multiple first sub-pixels M1A near the border area 20, providing conditions for more accurate adjustment of color shift.

[0048] In one embodiment of this application, reference continues to be made to... Figure 3 , Figure 4 As shown, the first sub-pixel M1A of the first type located in the first sub-region 101 includes a first part B1 and a second part B2. The first part B1 is adjacent to the border region 20 in the first direction X1, and the second part B2 is located on the side of the first part B1 away from the border region 20 in the first direction X1. The first part B1 of the first type of first sub-pixel M1A is closer to the border region 20 in the first direction X1. Compared with the second part B2, the emission of the first part B1 has a greater impact on the color shift at the position of the border region 20.

[0049] The second direction X2 intersects the first direction X1 on the plane parallel to the display panel 100.

[0050] In this embodiment, when setting the first type of first sub-pixel M1A, the maximum width of the first portion B1 in the second direction X2 is less than the minimum width of the second portion B2 in the second direction X2. This is beneficial because, in the second direction X2, the shape of the first type of first sub-pixel M1A is such that the light-emitting area of ​​the second portion B2 is greater than the light-emitting area of ​​the first portion B1, which helps to reduce the amount of light emitted by the first type of first sub-pixel M1A near the border area 20, thereby further reducing the color shift effect near the border area 20. In addition, the color shift can be improved more accurately by adjusting the area difference between the first portion B1 and the second portion B2 of the first type of first sub-pixel M1A.

[0051] Figure 5 Another embodiment provided in this application Figure 1 A schematic diagram of the central region E1.

[0052] In one embodiment of this application, such as Figure 4 , Figure 5 As shown, along the direction from the display area 10 to the border area 20 and parallel to the first direction X1, the width of the first portion B1 of the first type of first sub-pixel M1A gradually decreases in the second direction X2. This results in the first portion B1 of the first type of first sub-pixel M1A having a smaller light-emitting area as it gets closer to the border area 20 in the second direction X2, and consequently, a smaller amount of light emitted by the first portion B1 of the first type of first sub-pixel M1A as it gets closer to the border area 20 in the second direction X2. Overall, setting the width of the first portion B1 of the first type of first sub-pixel M1A to gradually decrease in the second direction X2 helps to make the total luminous intensity of the multiple first sub-pixels M1 in the first sub-area 101 gradually decrease as it gets closer to the border area 20 in the second direction X2. This reduces the sensitivity of the human eye to changes in the luminous brightness of the multiple first sub-pixels M1 within the first sub-area 101, improving the visual effect, while also adjusting for the color shift of the first sub-area 101.

[0053] Figure 6 Another embodiment provided in this application Figure 1 A schematic diagram of region E1 in the middle.

[0054] In one embodiment of this application, combined with Figure 1 , Figure 6 As shown, pixel M also includes a second sub-pixel M2, and the first sub-pixel M1 and the second sub-pixel M2 in the same pixel M are adjacent in the first direction X1. Optionally, the second sub-pixel M2 is a green sub-pixel. When the second sub-pixel M2 in multiple pixels M within the first sub-region 101 is closer to the border region 20 than the first sub-pixel M1, the position closer to the border region 20 will appear greenish when displayed on a white screen. Figure 1In at least two of the first sub-regions 101 shown, the portion of the border area 20 near the bottom of the display panel 100 exhibits a color biased towards the second sub-pixel M2. Optionally, pixel M also includes a third sub-pixel M3, which is a blue sub-pixel.

[0055] Combination Figure 2 As shown, in related technologies, the first sub-pixel and the second sub-pixel are adjacent in a first direction. Furthermore, if the first and second sub-pixels in multiple pixels are arranged in the same way, then when the positions near the border area are all first sub-pixels, the display color of the positions near the border area is biased towards the first sub-pixel in a white screen. Conversely, when the positions near the border area are all second sub-pixels, the display color of the positions near the border area is biased towards the second sub-pixel in a white screen.

[0056] In this embodiment, within the first sub-region X1, some pixels M have a first sub-pixel M1 located on the side of the second sub-pixel M2 near the second sub-region 102 in the first direction X1, and some pixels M have a second sub-pixel M2 located on the side of the first sub-pixel M1 near the second sub-region 102 in the first direction X1. This ensures that within the first sub-region X1, not all sub-pixels near the border area 20 are either the first sub-pixel M1 or the second sub-pixel M2. Reducing the number of first sub-pixels M1 and second sub-pixels M2 near the border area 20 helps to reduce the intensity of red or green near the border area 20, thereby reducing the color shift effect near the border area 20.

[0057] In one embodiment of this application, reference continues to be made to... Figure 6 As shown, within the second sub-region X2, the first sub-pixel M1 of pixel M is located on the side of the second sub-pixel M2 closest to the border region 20 in the first direction X1. In the second sub-region X2, the arrangement of the first sub-pixels M1 and second sub-pixels M2 of multiple pixels M is consistent, which helps to reduce the impact on the overall display effect of the display panel 100.

[0058] Figure 7 Another embodiment provided in this application Figure 1 A schematic diagram of region E1 in the middle.

[0059] In one embodiment of this application, such as Figure 7 As shown, within the first sub-region 101, the first sub-pixel M1 and the second sub-pixel M2 are arranged alternately along the second direction X2. The second direction X2 intersects the first direction X1 on a plane parallel to the display panel 100.

[0060] In this embodiment, the first sub-pixel M1 and the second sub-pixel M2 in the first sub-region 101 are arranged alternately along the second direction X2. This facilitates a more regular adjustment of the sub-pixel arrangement in the first sub-region 101, reduces the color shift effect near the border area 20, improves the display uniformity of the first sub-region 101, and enhances the overall display effect of the display panel 100.

[0061] Figure 8 Another embodiment provided in this application Figure 1 A schematic diagram of region E1 in the middle.

[0062] In one embodiment of this application, such as Figure 8 As shown, the display panel 100 also includes a plurality of pixel circuits 30. The pixel circuits 30 are electrically connected to the sub-pixels to drive the sub-pixels to emit light. The pixel circuits 30 can output a light-emitting driving current to the sub-pixels, thereby driving the sub-pixels to emit light. Generally, the smaller the light-emitting driving current generated by the pixel circuits 30, the smaller the brightness of the driven sub-pixels.

[0063] The plurality of pixel circuits 30 includes a first pixel circuit 301 and a second pixel circuit 302. The first pixel circuit 301 is electrically connected to at least a portion of the first sub-pixel M1 located in the first sub-region 101, and the light-emitting driving current generated by the first pixel circuit 301 drives the first sub-pixel M1 in the first sub-region 101 to emit light. The second pixel circuit 302 is electrically connected to the first sub-pixel M1 located in the second sub-region 102, and the light-emitting driving current generated by the second pixel circuit 302 drives the second sub-pixel M2 in the second sub-region 102 to emit light.

[0064] Specifically, the absolute value of the threshold voltage |Vth1| of the driving transistor T1 included in the first pixel circuit 301 is set to be greater than the absolute value of the threshold voltage |Vth2| of the driving transistor T2 in the second pixel circuit 302. The pixel circuit 30 includes driving transistors, which generate corresponding light-emitting driving currents upon receiving corresponding data voltage Vdata.

[0065] Optionally, the driving transistor T1 included in the first pixel circuit 301 and the driving transistor T2 included in the second pixel circuit 302 are both P-type transistors.

[0066] In related technologies, when the driving transistor in the pixel circuit is a P-type transistor, the threshold voltage of the driving transistor is negative. When the threshold voltage of the driving transistor is too small, that is, when its absolute value is too large, the light-emitting driving current generated by the driving transistor is too small; correspondingly, when the threshold voltage of the driving transistor is too large, that is, when its absolute value is too small, the light-emitting driving current generated by the driving transistor is too large.

[0067] When the driving transistor in the pixel circuit is an N-type transistor, the threshold voltage of the driving transistor is positive. When the threshold voltage of the driving transistor is small, that is, when its absolute value is also small, the light-emitting driving current generated by the driving transistor is large; correspondingly, when the threshold voltage of the driving transistor is large, that is, when its absolute value is also large, the light-emitting driving current generated by the driving transistor is small.

[0068] In general, when receiving the same power supply voltage and data voltage, the absolute value of the threshold voltage of the driving transistor is larger when it is P-type or N-type, and the resulting light-emitting driving current is smaller.

[0069] In this embodiment, the absolute value of the threshold voltage |Vth1| of the driving transistor T1 included in the first pixel circuit 301 is set to be greater than the absolute value of the threshold voltage |Vth2| of the driving transistor T2 in the second pixel circuit 302. This is beneficial to make the light-emitting driving current generated by the driving transistor T1 in the first pixel circuit 301 smaller, thereby making the light-emitting brightness of the first sub-pixel M1 driven by the first pixel circuit 301 weaker, reducing the light-emitting brightness of the first sub-pixel M1 in the first sub-region 101, and thus reducing the color shift effect near the edge region 20.

[0070] Figure 9 This is a comparative planar schematic diagram of the driving transistors included in a first pixel circuit and the active layer of the driving transistors included in a second pixel circuit, as provided in an embodiment of this application.

[0071] In one embodiment of this application, such as Figure 9 As shown, the aspect ratio N1 of the active layer Poly1 in the driving transistor T1 of the first pixel circuit 301 is smaller than the aspect ratio N2 of the active layer Poly2 in the driving transistor 302 of the second pixel circuit 302. Taking the example where the width W1 of the active layer Poly1 and the width W2 of the active layer Poly2 are equal, in this case... Figure 11 As shown, if the length L1 of the active layer Poly1 is greater than the length of the active layer Poly2, then the aspect ratio N1 of the active layer Poly1 in the driving transistor T1 included in the first pixel circuit 301 is less than the aspect ratio N2 of the active layer Poly2 in the driving transistor 302 included in the second pixel circuit 302.

[0072] Based on the current-voltage characteristics of the driving transistor, when the aspect ratio N1 of the active layer Poly1 is reduced, the surface area of ​​the active layer Poly1 is also reduced, the charging and discharging capability of the driving transistor T1 decreases, and the absolute value of the threshold voltage |Vth1| of the driving transistor T1 is correspondingly larger, which makes the light-emitting driving current generated by the driving transistor T1 smaller, thereby achieving the purpose of making the light-emitting brightness of the first sub-pixel M1 in the first sub-region 101 smaller and improving color shift.

[0073] Figure 10 Another embodiment provided in this application Figure 1 Schematic diagram of the central region E1.

[0074] In one embodiment of this application, such as Figure 10 As shown, the display panel 100 also includes a plurality of pixel circuits 30, which are electrically connected to the sub-pixels to drive the sub-pixels to emit light.

[0075] In the first sub-region 101, the same pixel circuit 30 is simultaneously electrically connected to at least two first sub-pixels M1. In this embodiment, the example of a pixel circuit 30 located in the second sub-region 102 being electrically connected to one first sub-pixel M1 is described.

[0076] In this embodiment, in the first sub-region 101, the same pixel circuit 30 simultaneously drives multiple first sub-pixels M1 to emit light. When the display panel 100 is displaying, the light emission driving current generated by the same pixel circuit 30 in the first sub-region 101 needs to be distributed to multiple first sub-pixels M1. This is beneficial because the light emission driving current received by the first sub-pixel M1 in the first sub-region 101 is less than the light emission driving current received by the first sub-pixel M1 in the second sub-region 102. This is beneficial because the light emission brightness of the first sub-pixel M1 in the first sub-region 101 is less than the light emission brightness of the first sub-pixel M1 in the second sub-region 102, thereby reducing the color shift near the border area 20.

[0077] It should be noted that when the first sub-pixel M1 is a red sub-pixel, the second sub-pixel M2 can be a green sub-pixel. When the first sub-pixel M1 is a green sub-pixel, the second sub-pixel M2 can be a red sub-pixel. In some cases, the white screen of the display panel 100 may have different color biases near the top and bottom edges in the first direction X1. For example, the area near the top edge may be biased towards red, while the area near the bottom edge may be biased towards green. In this case, this application can simultaneously adjust the sub-pixels in multiple first sub-regions 101 near the top and bottom edges in the first direction X1 to improve the color bias of the top and bottom edges.

[0078] Figure 11 This is a plan view of another display panel provided in an embodiment of this application.

[0079] For example, such as Figure 11As shown, in the display panel 100, at least a portion of the first sub-pixels M1 in the first sub-region 101 near the upper border in the first direction X1 have light-emitting areas smaller than the first sub-pixels M1 in the second sub-region 102. Simultaneously, in the display panel 100, at least a portion of the second sub-pixels M2 in the first sub-region 101 near the lower border in the first direction X1 have light-emitting areas smaller than the second sub-pixels M2 in the second sub-region 102. This is beneficial for simultaneously improving color shift near both the upper and lower borders of the display panel 100. Optionally, the shape of at least a portion of the first sub-pixels M1 in the first sub-region 101 near the upper border in the first direction X1 is the same as the shape of the first sub-pixels M1 in the second sub-region 102. Optionally, the shape of at least a portion of the second sub-pixels M2 in the first sub-region 101 near the lower border in the first direction X1 is the same as the shape of the second sub-pixels M1 in the second sub-region 102.

[0080] Figure 12 This is a plan view of another display panel provided in an embodiment of this application.

[0081] For example, such as Figure 12 As shown, the shape of at least a portion of the first sub-pixels M1 in the first sub-region 101 near the top border in the first direction X1 of the display panel 100 is different from the shape of the first sub-pixels M1 in the second sub-region 102. Simultaneously, the shape of at least a portion of the second sub-pixels M2 in the first sub-region 101 near the bottom border in the first direction X1 of the display panel 100 is different from the shape of the second sub-pixels M2 in the second sub-region 102. This is beneficial for simultaneously improving the color shift in the display panel 100 near both the top and bottom borders.

[0082] Figure 13 This is a plan view of another display panel provided in an embodiment of this application.

[0083] For example, such as Figure 13 As shown, the display panel 100 includes pixels M, wherein pixels M include a first sub-region 101 in the display panel 100 near the top border along the first direction X1, in which a first sub-pixel M1 and a second sub-pixel M2 are alternately arranged along the second direction X2. Simultaneously, in the first sub-region 101 in the display panel 100 near the bottom border along the first direction X1, the first sub-pixel M1 and the second sub-pixel M2 in the first sub-region 101 are also alternately arranged along the second direction X2, which helps to simultaneously improve the color shift in the display panel 100 near both the top and bottom borders.

[0084] Figure 14 This is a plan view of another display panel provided in an embodiment of this application.

[0085] For example, such as Figure 14 As shown, the display panel 100 includes a pixel circuit 30. A first pixel circuit 301 is located in a first sub-region 101 near the upper frame in the first direction X1 of the display panel 100. The first pixel circuit 301 drives a first sub-pixel M1 in this region. A second pixel circuit 302 is located in a second sub-region 102 and drives the first sub-pixel M1 in this region. Setting the absolute value of the threshold voltage of the driving transistor included in the first pixel circuit 301 to be smaller than the absolute value of the threshold voltage of the driving transistor included in the second pixel circuit 302 is beneficial because it makes the light-emitting driving current generated by the first pixel circuit 301 smaller than that generated by the second pixel circuit 302, thereby reducing the light-emitting brightness of the first sub-pixel M1 driven by the first pixel circuit 301, and thus improving the color shift near the upper frame of the display panel 100.

[0086] Meanwhile, the third pixel circuit 303 is located in the first sub-region 101 of the display panel 100 near the lower border in the first direction X1, and the third pixel circuit 303 is used to drive the second sub-pixel M2 in this region. The fourth pixel circuit 304 is located in the second sub-region 102, and the fourth pixel circuit 304 is used to drive the second sub-pixel M2 in this region. Setting the absolute value of the threshold voltage of the driving transistor included in the third pixel circuit 303 to be smaller than the absolute value of the threshold voltage of the driving transistor included in the fourth pixel circuit 304 is beneficial to make the light-emitting driving current generated by the third pixel circuit 303 smaller than that generated by the fourth pixel circuit 304, thereby reducing the light-emitting brightness of the second sub-pixel M2 driven by the third pixel circuit 303, thereby improving the color shift near the lower border of the display panel 100.

[0087] Figure 15 This is a plan view of another display panel provided in an embodiment of this application.

[0088] For example, such as Figure 15 As shown, the display panel 100 includes a pixel circuit 30, which is electrically connected to sub-pixels to drive them to emit light. In a first sub-region 101 near the upper edge of the display panel 100 in the first direction X1, the same pixel circuit 30 is simultaneously electrically connected to at least two first sub-pixels M2. This reduces the amount of light-emitting current received by the first sub-pixels M1 in this region, thereby reducing the brightness of the first sub-pixels M1 in this region and improving color shift near the upper edge of the display panel 100.

[0089] Meanwhile, in the first sub-region 101 near the lower border in the first direction X1 of the display panel 100, the same pixel circuit 30 is electrically connected to at least two second sub-pixels M2 simultaneously, thereby reducing the amount of light-emitting current received by the second sub-pixels M2 in the region and reducing the light-emitting brightness of the second sub-pixels M2 in the region, thereby improving the color shift near the upper border of the display panel 100.

[0090] Figure 16 This is a schematic diagram of a display device provided in an embodiment of this application.

[0091] This application provides a display device 200, including the display panel 100 as described in the above embodiments. The display device 200 can be a computer, television, mobile phone, or other device capable of display.

[0092] In the display device 20, the luminous intensity of some first sub-pixels M1 located in the first sub-region 101 is set to be less than that of the first sub-pixels M1 in the second sub-region 102. This helps to reduce the total luminous intensity emitted by the first sub-pixels M1 located in the first sub-region 101, thereby reducing the luminous intensity of the first sub-pixels M1 near the border area 20. This reduces the color shift caused by multiple first sub-pixels M1 near the border area 20 and improves the white screen display effect of the display panel 100.

[0093] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the scope of protection of this application.
