[0025] In order to better understand the technical solution of the present application, the embodiments of the present application are described in detail below with reference to the accompanying drawings.

[0026] It should be clear that the described embodiments are only part of the embodiments of the present application, rather than all the embodiments.

[0030] It should be understood that although the terms first, second, etc. may be used to describe sub-areas, sub-pixels, directions, etc. in the embodiments of the present application, these should not be limited to these terms. These terms are only used to distinguish sub-areas, sub-pixels, directions, etc. from each other. For example, without departing from the scope of the embodiments of the present application, the first sub-area may also be referred to as the second sub-area, and similarly, the second sub-area may also be referred to as the first sub-area. The applicant of this case has provided a solution to the problems existing in the prior art through careful and in-depth research.

[0031] Figure 1 A schematic plan view of a display panel provided in an embodiment of the present application.

[0032] The present application embodiment provides a display panel 100, such as Figure 1As shown, the display area 10 and the frame area 20 are included, and the frame area 20 surrounds 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 frame area 20 in the first direction X1, and the second sub-area 102 is adjacent to the first sub-area 101 in the first direction X1, and the second sub-area 102 is located on the side of the first sub-area 101 away from the frame area 20 in the first direction X1. There are at least two first sub-areas 101 along the first direction X1, and the two first sub-areas 101 are adjacent to the frame area 20 in the first direction X1, and the second sub-area 102 is located between the two first sub-areas 101 in the first direction X1.

[0033] In the related art, the first sub-area in the display panel is adjacent to the frame area, and no other display area is included between the first sub-area and the frame area. Since the sub-pixels in the first sub-area are arranged in the same manner, that is, there are multiple first sub-pixels of the same color emitting light at positions near the frame area in the first sub-area, and there is no light of other colors to be reconciled between the first sub-pixel and the frame area, the positions near the frame area show that the light output of multiple first sub-pixels is more concentrated and the color is more prominent. For example, each pixel includes a first sub-pixel, a second sub-pixel, and a third sub-pixel, and the luminous color of the first sub-pixel can be red, the luminous color of the second sub-pixel is green, and the luminous color of the third sub-pixel is blue. Among them, the human eye is more sensitive to red light and green light. When the positions near the frame area in the first sub-area are all first sub-pixels, the positions near the frame area in the white screen of the display panel are reddish. Or, when the positions near the frame area in the first sub-area are all second sub-pixels, the positions near the frame area in the white screen of the display panel are greenish. The above color shift performances all reduce the display effect of the display panel.

[0034] The display area 10 includes a plurality of pixels M, and the pixel M includes a first sub-pixel M1. As can be seen from the above-mentioned related technologies, the human eye is more sensitive to red light and green light, and the portion of the display panel 100 close to the border area A20 is prone to a reddish or greenish color cast when the screen is white. In the technical solution of the present application, the first sub-pixel M1 is a red sub-pixel for illustration. In some other embodiments, the first sub-pixel M1 may also be other colors.

[0035] The sub-pixels in the pixel M1 of the display panel 100 are arranged in a manner as follows: Figure 1 The following is an example for explanation, and the first sub-area 101 of the at least two first sub-areas 101 close to the portion of the frame area 20 above the display panel 100 in the first direction X1 is taken as an example for explanation. Figure 1As shown, in a pixel M1, the distance between the first sub-pixel M1 and part of the frame area 20 in the first direction X1 is relatively close, and the first sub-pixel M1 located in the first sub-area 102 has a relatively obvious color shift effect on the display of the white picture. Optionally, the sub-pixel arrangement mode of the multiple pixels M in the second sub-area 102 is the same as the sub-pixel arrangement mode of the multiple pixels M in the first sub-area 102. However, the second sub-area 102 is far away from the frame area 20 in the first direction X1, so the first sub-pixel M1 in the second sub-area 102 has almost no effect on the display of the white picture when displaying.

[0036] The brightness of at least some of the first sub-pixels M1 in the first sub-region 101 is set to be lower than the brightness of the first sub-pixels M1 in the second sub-region 102. Then, the luminous intensity of some of the first sub-pixels M1 with reduced brightness in the first sub-region 101 is reduced. In general, the total luminous brightness of the plurality of first sub-pixels M1 in the first sub-region 101 is reduced, so that the light emitted by the plurality of first sub-pixels M1 near the border region 20 is reduced in visibility.

[0037] In the embodiment of the present application, the luminous brightness of some first sub-pixels M1 located in the first sub-area 101 is set to be lower than the luminous brightness of the first sub-pixels M1 in the second sub-area 102, which is beneficial to reducing the total luminous intensity emitted by the first sub-pixels M1 located in the first sub-area 101, so that the luminous intensity of the first sub-pixels M1 near the border area 20 is significantly reduced, thereby reducing the color deviation caused by multiple first sub-pixels M1 near the border area 20, and improving the white screen display effect of the display panel 100.

[0038] Figure 2 A method provided in the embodiment of the present application Figure 1 Schematic plan view of the middle area E1.

[0039] In one embodiment of the present application, Figure 1 , Figure 2 As shown, the plurality of first sub-pixels M1 located in the first sub-region 101 include first-type first sub-pixels M1A, and the first-type first sub-pixels M1A are adjacent to the frame region 20 in the first direction X1. In some technical solutions, part of the first sub-pixels M1 located in the first sub-region 101 may be adaptively selected as the first-type first sub-pixels M1A according to the degree of influence of the plurality of first sub-pixels M1 in the first sub-region 101 on the color shift, or all the first sub-pixels M1 located in the first sub-region 101 may be the first-type first sub-pixels M1A.

[0040] The light emitting area of ​​the first sub-pixel M1A of the first category is set to be smaller than the light emitting area of ​​the first sub-pixel M1 located in the second sub-region 102. When the light emitting driving current received by the first sub-pixel M1A of the first category is equal to the light emitting current received by the first sub-pixel M1 of the first category and the first sub-pixel M1 located in the second sub-region 102, the light emitting amount of the first sub-pixel M1A of the first category is equal to the light emitting amount of the first sub-pixel M1 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 category are equal to the light emitting areas of the plurality of first sub-pixels M1 located in the second sub-region 102.

[0041] In the embodiment of the present application, the light emitting area of ​​the first type first sub-pixel M1A located in the first sub-region 101 is set to be smaller than the light emitting area of ​​the first sub-pixel M1 located in the second sub-region 102, which is beneficial to reducing the total light emitting amount of the first sub-pixel M1 located in the first sub-region 101, thereby facilitating reducing the total light emitting brightness of the multiple sub-pixels M1 located in the first sub-region 101, and reducing the color deviation effect of the first sub-pixel M1 located in the first sub-region 101 on the position of the border region 20.

[0042] In one embodiment of the present application, continue to refer 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 the embodiment of the present application, the first sub-pixel M1A of the first type located in the first sub-region 101 and the first sub-pixel M1 located in the second sub-region 102 are different in area but have the same shape, and the light emitting area of ​​the first sub-pixel M1A of the first type 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 is conducive to reducing the complexity of preparing the first sub-pixel M1A of the first type, thereby reducing the cost of preparing the first sub-pixel M1A of the first type, and improving the preparation efficiency of the first sub-pixel M1A of the first type.

[0044] Figure 3 Another embodiment provided in this application is Figure 1 Schematic diagram of the middle area E1, Figure 4 Another embodiment provided in this application is Figure 1 Schematic plan view of the middle area E1.

[0045] In one embodiment of the present application, Figure 3 , Figure 4 As shown, the shape of the first sub-pixel M1A of the first type 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. Figure 3 , Figure 4As shown, the shape of the first sub-pixel M1 other than the first-type first sub-pixel M1 in the second sub-region 102 is the same as the shape of the first sub-pixel M1 in the second sub-region 102 for description.

[0046] Alternatively, if Figure 3 As shown, the shape of the first sub-pixel M1A of the first type located in the first sub-region 101 is a convex shape, and the shape of the first sub-pixel M1 located in the second sub-region 102 is a rectangle. Figure 4 As shown, the shape of the first sub-pixel M1A of the first type located in the first sub-region 101 is a triangle, and the shape of the first sub-pixel M1 located in the second sub-region 102 is a rectangle.

[0047] In the embodiment of the present application, the first-type first sub-pixel M1A located in the first sub-area 101 and the first sub-pixel M1 located in the second sub-area 102 are different in area and shape. This is conducive to adaptively selecting the shape of the first-type first sub-pixel M1A according to the degree of color deviation near the border area 20 in the display panel 100. In some technical schemes, the different shapes of the first-type first sub-pixels M1A can be used to adjust the light output of a first-type first sub-pixel M1A at different positions, thereby more accurately adjusting the total luminous brightness of multiple first sub-pixels M1A near the border area 20, thereby providing conditions for more accurately adjusting the color deviation.

[0048] In one embodiment of the present application, continue to refer to Figure 3 , Figure 4 As shown, the first type of first sub-pixel M1A located in the first sub-region 101 includes a first portion B1 and a second portion B2, the first portion B1 is adjacent to the border region 20 in the first direction X1, and the second portion B2 is located on a side of the first portion B1 away from the border region 20 in the first direction X1. The first portion B1 in the first type of first sub-pixel M1A is closer to the border region 20 in the first direction X1, and the light emission of the first portion B1 has a greater impact on the color deviation of the border region 20 than the second portion B2.

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

[0050] In the embodiment of the present application, when the first sub-pixel M1A of the first type is set, the maximum width of the first portion B1 in the second direction X2 is smaller than the minimum width of the second portion B2 in the second direction X2. This is beneficial to make the shape of the first sub-pixel M1A of the first type in the second direction X2 present that the light emitting area of ​​the second portion B2 is larger than the light emitting area of ​​the first portion B1, thereby facilitating the reduction of the light emitting amount of the first sub-pixel M1A of the first type at a position close to the border area 20, thereby further reducing the color deviation effect at a position close to the border area 20. In addition, the color deviation can be improved more accurately by adjusting the area difference between the first portion B1 and the second portion B2 of the first sub-pixel M1A of the first type.

[0051] Figure 5 Another embodiment provided in this application Figure 1 Schematic plan view of the middle area E1.

[0052] In one embodiment of the present application, Figure 4 , Figure 5 As shown, along the direction from the display area 10 to the frame area 20 and parallel to the first direction X1, the width of the first part B1 of the first sub-pixel M1A of the first category in the second direction X2 gradually decreases, so that the closer the first part B1 of the first sub-pixel M1A of the first category is to the frame area 20 in the second direction X2, the smaller the light emitting area thereof is, and thus the closer the first part B1 of the first sub-pixel M1A of the first category is to the frame area 20 in the second direction X2, the smaller the light emitting amount thereof is. In general, setting the width of the first part B1 of the first sub-pixel M1A of the first category in the second direction X2 to gradually decrease is conducive to making the total luminous intensity of the multiple first sub-pixels M1 in the first sub-region 101 gradually decrease as it approaches the frame area 20 in the second direction X2, so that on the basis of adjusting the color shift effect of the first sub-region 101, the sensitivity of the human eye to the change of the luminous brightness of the multiple first sub-pixels M1 in the first sub-region 101 is reduced, thereby improving the visual effect.

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

[0054] In one embodiment of the present application, Figure 1 , Figure 6 As shown, the 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 to each other in the first direction X1. Optionally, the second sub-pixel M2 is a green sub-pixel. When the second sub-pixel M2 in the plurality of pixels M in the first sub-area 101 is closer to the border area 20 than the first sub-pixel M1, the position close to the border area 20 will be green when the white screen is displayed. Figure 1In the at least two first sub-areas 101 shown, the portion of the frame area 20 near the bottom of the display panel 100 has a light color that is biased toward the second sub-pixel M2. Optionally, the pixel M further includes a third sub-pixel M3, which is a blue sub-pixel.

[0055] Combination Figure 2 As shown, in the related art, the first sub-pixel and the second sub-pixel are adjacent in the first direction. Moreover, the first sub-pixel and the second sub-pixel in the plurality of pixels are arranged in the same manner. If the positions close to the border area are all first sub-pixels, then in a white screen, the positions close to the border area tend to display the display color of the first sub-pixel. If the positions close to the border area are all second sub-pixels, then in a white screen, the positions close to the border area tend to display the display color of the second sub-pixel.

[0056] In the embodiment of the present application, the first sub-pixel M1 of some pixels M is located on the side of the second sub-pixel M2 close to the second sub-region 102 in the first direction X1, and the second sub-pixel M2 of some pixels M is located on the side of the first sub-pixel M1 close to the second sub-region 102 in the first direction X1. Therefore, in the first sub-region X1, not all of the multiple sub-pixels close to the border region 20 are the first sub-pixel M1 or the second sub-pixel M2, and the number of the first sub-pixels M1 close to the border region 20 is reduced, and the number of the second sub-pixels M2 close to the border region 20 is reduced, which is conducive to reducing the obvious degree of red or green near the border region 20, thereby reducing the color shift effect near the border region 20.

[0057] In one embodiment of the present application, continue to refer to Figure 6 As shown, in the second sub-area X2, the first sub-pixel M1 of the pixel M is located on the side of the second sub-pixel M2 close to the frame area 20 in the first direction X1. In the second sub-area X2, the first sub-pixels M1 and the second sub-pixels M2 of the plurality of pixels M are arranged in the same manner, which is beneficial to reduce the impact on the overall display effect of the display panel 100.

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

[0059] In one embodiment of the present application, Figure 7 As shown, in the first sub-area 101 , the first sub-pixels M1 and the second sub-pixels M2 are alternately arranged 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 the embodiment of the present application, the first sub-pixels M1 and the second sub-pixels M2 in the first sub-area 101 are arranged alternately along the second direction X2, which is conducive to more regularly adjusting the sub-pixel arrangement in the first sub-area 101, while reducing the influence of color deviation near the border area 20, improving the display uniformity of the first sub-area 101, and improving the overall display effect of the display panel 100.

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

[0062] In one embodiment of the present application, Figure 8 As shown, the display panel 100 further includes a plurality of pixel circuits 30, which are electrically connected to the sub-pixels to drive the sub-pixels to emit light, and 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 circuit 30, the smaller the light-emitting brightness of the driven sub-pixels.

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

[0064] The threshold voltage absolute value |Vth1| of the driving transistor T1 included in the first pixel circuit 301 is set to be smaller than the threshold voltage absolute value |Vth2| of the driving transistor T2 in the second pixel circuit 302. The pixel circuit 30 includes a driving transistor, which generates a corresponding light-emitting driving current when receiving a 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 the related art, when the driving transistor in the pixel circuit is a P-type transistor, the threshold voltage of the driving transistor is a negative value. When the threshold voltage of the driving transistor is relatively small, that is, when the absolute value of its threshold voltage is relatively large, the light-emitting driving current generated by the driving transistor is relatively large; correspondingly, when the threshold voltage of the driving transistor is relatively large, that is, when the absolute value of its threshold voltage is relatively small, the light-emitting driving current generated by the driving transistor is relatively small.

[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 relatively small, that is, the absolute value of the threshold voltage is also relatively small, the luminous driving current generated by the driving transistor is relatively large; correspondingly, when the threshold voltage of the driving transistor is relatively large, that is, the absolute value of the threshold voltage is also relatively large, the luminous driving current generated by the driving transistor is relatively small.

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

[0069] In the embodiment of the present application, the threshold voltage absolute value |Vth1| of the driving transistor T1 included in the first pixel circuit 301 is set to be smaller than the threshold voltage absolute value |Vth2| of the driving transistor T2 in the second pixel circuit 302, which is beneficial for making 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-area 101, thereby reducing the color deviation effect near the border area 20.

[0070] Fig. 9 A schematic plan view showing a comparison of active layers of a driving transistor included in a first pixel circuit and a driving transistor included in a second pixel circuit provided in an embodiment of the present application.

[0071] In one embodiment of the present application, Fig. 9 As shown, the aspect ratio N1 of the active layer Poly1 in the driving transistor T1 included in the first pixel circuit 301 is smaller than the aspect ratio N2 of the active layer Poly2 in the driving transistor 302 included in the second pixel circuit 302. Take the example that the width W1 of the active layer Poly1 is equal to the width W2 of the active layer Poly2. Fig.11 As shown, the length L1 of the active layer Poly1 is set to be smaller 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 smaller than the aspect ratio N2 of the active layer Poly2 in the driving transistor 302 included in the second pixel circuit 302.

[0072] According to the volt-ampere characteristic 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, and the charge and discharge capacity of the driving transistor T1 is reduced. Correspondingly, the absolute value of the threshold voltage |Vth1| of the driving transistor T1 is smaller, so that the light-emitting driving current generated by the driving transistor T1 is smaller, thereby achieving the purpose of making the first sub-pixel M1 in the first sub-area 101 emit less brightness and improving color deviation.

[0073] Fig.10 Another embodiment provided in this application is Figure 1 Schematic diagram of the plan view of the middle area E1.

[0074] In one embodiment of the present application, Fig.10 As shown, the display panel 100 further includes a plurality of pixel circuits 30 , and the pixel circuits 30 are electrically connected to the sub-pixels to drive the sub-pixels to emit light.

[0075] In the first sub-area 101, the same pixel circuit 30 is electrically connected to at least two first sub-pixels M1 at the same time. In the embodiment of the present application, an example is taken that a pixel circuit 30 in the second sub-area 102 is electrically connected to a first sub-pixel M1.

[0076] In the embodiment of the present application, the same pixel circuit 30 is arranged in the first sub-area 101, and drives multiple first sub-pixels M1 to emit light at the same time. Then, when the display panel 100 is displaying, the light-emitting drive current generated by the same pixel circuit 30 located in the first sub-area 101 needs to be diverted to multiple first sub-pixels M1, which is beneficial for making the light-emitting drive current received by the first sub-pixel M1 in the first sub-area 101 smaller than the light-emitting drive current received by the first sub-pixel M1 in the second sub-area 102, thereby facilitating the light-emitting brightness of the first sub-pixel M1 in the first sub-area 101 to be smaller than the light-emitting brightness of the first sub-pixel M1 located in the second sub-area 102, thereby reducing the degree of color deviation 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 may be a green sub-pixel. When the first sub-pixel M1 is a green sub-pixel, the second sub-pixel M2 may be a red sub-pixel. In some cases, there is a situation where the positions near the upper frame and the positions near the lower frame in the first direction X1 in the white screen of the display panel 100 tend to display different colors, for example, the position near the upper frame tends to display red, while the position near the lower frame tends to display green. In this case, the present application can simultaneously adjust the sub-pixels near the upper frame and the lower frame in the first direction X1 in multiple first sub-areas 101 at the same time to improve the color deviation of the upper frame and the lower frame.

[0079] For example, Fig.11As shown, the light emitting areas of at least some of the first sub-pixels M1 in the first sub-area 101 close to the upper frame in the first direction X1 of the display panel 100 are all smaller than the light emitting areas of the first sub-pixels M1 in the second sub-area 102, and at the same time, the light emitting areas of at least some of the second sub-pixels M2 in the first sub-area 101 close to the lower frame in the first direction X1 of the display panel 100 are all smaller than the light emitting areas of the second sub-pixels M2 in the second sub-area 102. This is conducive to improving the display color deviation near the upper frame and the lower frame in the display panel 100 at the same time. Optionally, the shape of at least some of the first sub-pixels M1 in the first sub-area 101 close to the upper frame in the first direction X1 of the display panel 100 is the same as the shape of the first sub-pixels M1 in the second sub-area 102. Optionally, the shape of at least some of the second sub-pixels M2 in the first sub-area 101 close to the lower frame in the first direction X1 of the display panel 100 is the same as the shape of the second sub-pixels M1 in the second sub-area 102.

[0080] Fig.12 A schematic plan view of another display panel provided in an embodiment of the present application.

[0081] For example, Fig.12 As shown, the shape of at least part of the first sub-pixels M1 in the first sub-region 101 close to the upper frame in the first direction X1 of the display panel 100 is set to be different from the shape of the first sub-pixels M1 in the second sub-region 102. At the same time, the shape of at least part of the second sub-pixels M2 in the first sub-region 101 close to the lower frame in the display panel 100 in the first direction X1 is set to be different from the shape of the second sub-pixels M2 in the second sub-region 102, which is conducive to improving the display color deviation near the upper frame and the lower frame in the display panel 100 at the same time.

[0082] Fig.13 A schematic plan view of another display panel provided in an embodiment of the present application.

[0083] For example, Fig.13 As shown, the display panel 100 includes pixels M, wherein the pixels M include a first sub-pixel M1 and a second sub-pixel M2 arranged alternately along the second direction X2 in a first sub-region 101 close to the upper frame in the first direction X1 of the display panel 100. At the same time, in a first sub-region 101 close to the lower frame in the first direction X1 of the display panel 100, 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, which is conducive to improving the display color deviation near the upper frame and the lower frame of the display panel 100 at the same time.

[0084] Fig.14 A schematic plan view of another display panel provided in an embodiment of the present application.

[0085] For example, Fig.14 As shown, the display panel 100 includes a pixel circuit 30, wherein a first pixel circuit 301 is located in a first sub-area 101 close to an upper frame in a first direction X1 of the display panel 100, and the first pixel circuit 301 is used to drive a first sub-pixel M1 in the area. A second pixel circuit 302 is located in the second sub-area 102, and is used to drive the first sub-pixel M1 in the area. 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 conducive to making the light-emitting driving current generated by the first pixel circuit 301 smaller than the light-emitting driving current 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, thereby improving the color deviation near the upper frame of the display panel 100.

[0086] At the same time, the third pixel circuit 303 is located in the first sub-area 101 of the display panel 100 near the lower frame in the first direction X1, and the third pixel circuit 303 is used to drive the second sub-pixel M2 in the area. The fourth pixel circuit 304 is located in the second sub-area 102, and the fourth pixel circuit 304 is used to drive the second sub-pixel M2 in the area. 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 conducive to making the light-emitting driving current generated by the third pixel circuit 303 smaller than the light-emitting driving current 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 deviation near the lower frame of the display panel 100.

[0088] For example, Fig.15 As shown, the display panel 100 includes a pixel circuit 30, and the pixel circuit 30 is electrically connected to the sub-pixel to drive the sub-pixel to emit light. In the first sub-area 101 of the display panel 100 close to the upper frame in the first direction X1, the same pixel circuit 30 is electrically connected to at least two first sub-pixels M2 at the same time, so as to reduce the magnitude of the light-emitting current received by the first sub-pixel M1 in the area, reduce the light-emitting brightness of the first sub-pixel M1 in the area, and thus improve the color deviation near the upper frame of the display panel 100.

[0089] At the same time, in the first sub-area 101 of the display panel 100 close to the lower frame in the first direction X1, the same pixel circuit 30 is electrically connected to at least two second sub-pixels M2 at the same time, thereby reducing the luminous current received by the second sub-pixel M2 in the area and reducing the luminous brightness of the second sub-pixel M2 in the area, thereby improving the color deviation near the upper frame of the display panel 100.

[0092] In the display device 20, the luminous brightness of some first sub-pixels M1 located in the first sub-area 101 is set to be lower than the luminous brightness of the first sub-pixels M1 in the second sub-area 102, which is beneficial to reducing the total luminous intensity emitted by the first sub-pixels M1 located in the first sub-area 101, so that the luminous intensity of the first sub-pixels M1 near the border area 20 is significantly reduced, thereby reducing the color deviation caused by multiple first sub-pixels M1 near the border area 20, and improving the white screen display effect of the display panel 100.
