It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0034] The present application will be described in detail below with reference to the drawings and embodiments.

[0035] Please refer to Figures 1-7The display panel includes a display area 101 and a light-transmissive area 102, and the display area 101 is arranged around the light-transmissive area 102. The light-transmissive area 102 is configured as a light-transmissive area, and a photosensitive component, for example, a camera, can be integrated in the light-transmissive area 102. In this embodiment, the shape of the light-transmissive area 102 is circular. The shape of the light-transmissive area 102 is not limited to circular, and can be designed according to actual needs.

[0036] The display panel includes a substrate 10 and a plurality of pixel circuits 11 arranged on one side of the substrate 10. The plurality of pixel circuits 11 are arranged in an array in the display area 101. Each row of pixel circuits 11 includes a plurality of pixel circuits 11, and each column of pixel circuits 11 includes a plurality of pixel circuits 11. The plurality of columns of pixel circuits 11 are arranged along a first direction X. The arrangement direction of the plurality of pixel circuits 11 in each column is defined as a second direction Y. The second direction Y is perpendicular to the first direction X.

[0037] The display area 101 includes a first sub-display area 1011 and a second sub-display area 1012 located on both sides of the light-transmissive area 102 along the second direction Y. The display area 101 has opposite first and second boundaries A1 and A2 along the second direction Y. The area between the boundary line on the side of the light-transmissive area 102 close to the first boundary A1 and the first boundary A1 is the first sub-display area 1011. The area between the boundary line on the side of the light-transmissive area 102 close to the second boundary A2 and the second boundary A2 is the second sub-display area 1012. In this embodiment, the distance between the light-transmissive area 102 and the first boundary A1 is smaller than the distance between the light-transmissive area 102 and the second boundary A2. That is, the size of the first sub-display area 1011 along the second direction Y is smaller than the size of the second sub-display area 1012 along the second direction Y. In other embodiments, the size of the first sub-display area 1011 along the second direction Y can be greater than the size of the second sub-display area 1012 along the second direction Y, or the size of the first sub-display area 1011 along the second direction Y can be equal to the size of the second sub-display area 1012 along the second direction Y. This application only takes the example that the size of the first sub-display area 1011 along the second direction Y is smaller than the size of the second sub-display area 1012 along the second direction Y to introduce the specific arrangement mode of the pixel circuits 11 in the first and second sub-display areas 1011 and 1012, and is not limited thereto.

[0038] The plurality of pixel circuits 11 in each row are arranged at intervals. Along the first direction X, the plurality of pixel circuits 11 in each column on both sides of the light-transmissive area 102 are connected in sequence. The plurality of pixel circuits 11 in each column of the first sub-display area 1011 are connected in sequence. The plurality of pixel circuits 11 in each column of the second sub-display area 1012 are connected in sequence. At least one column of pixel circuits 11 in the first sub-display area 1011 is connected to at least one column of pixel circuits 11 in the other display area 101 except the first sub-display area 1011.

[0039] In an embodiment, the pixel circuit 11 includes a transistor (not shown in the figure), and the pixel circuit 11 is connected to another pixel circuit 11 through an active layer of the transistor. It should be noted that the connection between the pixel circuits 11 described in the present application is achieved through the active layer. The active layer can be a silicon semiconductor layer, for example, a polycrystalline silicon (pSi) layer, a low temperature polycrystalline silicon (LTPS) layer. In the present embodiment, the active layer is a pSi layer. The active layer is not limited to the above-mentioned materials, and can also be other silicon semiconductor layers such as monocrystalline silicon, or an oxide semiconductor layer such as indium gallium zinc oxide (IGZO).

[0040] Since the size of the first sub-display area 1011 along the second direction Y is smaller than the size of the second sub-display area 1012 along the second direction Y, the length of the plurality of pixel circuits 11 in each column in the first sub-display area 1011 after being connected in sequence is a first value, the length of the plurality of pixel circuits 11 in each column in the second sub-display area 1012 after being connected in sequence is a second value, and the first value is smaller than the second value; along the first direction X, the length of the plurality of pixel circuits 11 in each column of the display area 101 on both sides of the light-transmitting area 102 after being connected in sequence is a third value, and the second value is smaller than the third value. Since the first value and the third value differ greatly, it is easy to cause the transistor characteristics of the first sub-display area 1011 to be different from the transistor characteristics of the display area 101 located on at least one side of the light-transmitting area 102 in the first direction X, forming regional transistor characteristic differences, causing the brightness of the first sub-display area 1011 to be different from the brightness of the display area 101 located on at least one side of the light-transmitting area 102 in the first direction X, and causing uneven display. The present application connects at least one column of pixel circuits 11 of the first sub-display area 1011 to at least one column of pixel circuits 11 of the display area 101 other than the first sub-display area 1011, thereby weakening the regional transistor characteristic differences caused by the length difference of the plurality of pixel circuits 11 in each column of the display area 101 after being connected in sequence, making the characteristics of the transistors with the same function in the display area 101 consistent, improving the display effect of the display area 101, and facilitating the improvement of the uniformity of the display picture of the display area 101.

[0041] In an embodiment, each column of pixel circuits 11 in the first sub-display area 1011 is connected to at least one column of pixel circuits 11 in the other display area 101 than the first sub-display area 1011. In other words, all columns of pixel circuits 11 in the first sub-display area 1011 are connected to at least one column of pixel circuits 11 in the other display area 101 than the first sub-display area 1011; specifically, the end pixel circuits 11 of all columns of pixel circuits 11 in the first sub-display area 1011 are connected in sequence, and the end pixel circuits 11 of the column of pixel circuits 11 closest to the boundary line of the first sub-display area 1011 are connected to at least one column of pixel circuits 11 in the other display area 101 than the first sub-display area 1011. By connecting each column of pixel circuits 11 in the first sub-display area 1011 to at least one column of pixel circuits 11 in the other display area 101 than the first sub-display area 1011, the display effect of the first sub-display area 1011 is improved, the display unevenness of the first sub-display area 1011 and the other display area 101 due to the difference in regional transistor characteristics is weakened, and the uniformity of the display picture of the display area 101 is further improved.

[0042] In an embodiment, on the basis of the connection of at least one column of pixel circuits 11 in the first sub-display area 1011 to at least one column of pixel circuits 11 in the other display area 101 than the first sub-display area 1011, at least one column of pixel circuits 11 in the second sub-display area 1012 is connected to at least one column of pixel circuits 11 in the other display area 101 than the second sub-display area 1012.

[0043] It can be understood that the length of the plurality of pixel circuits 11 in each column in the second sub-display area 1012 after being connected in sequence is a second value; the length of the plurality of pixel circuits 11 in each column of the display area 101 on both sides of the light-transmitting area 102 along the first direction X after being connected in sequence is a third value, and the second value is less than the third value. Due to the large difference between the second value and the third value, it is easy to cause the transistor characteristics of the second sub-display area 1012 to be different from the transistor characteristics of the display area 101 located on at least one side of the light-transmitting area 102 in the first direction X, forming regional transistor characteristic differences, causing the brightness of the second sub-display area 1012 to be different from the brightness of the display area 101 located on at least one side of the light-transmitting area 102 in the first direction X, and the phenomenon of uneven display appears. Based on the connection of each column of pixel circuits 11 in the first sub-display area 1011 to at least one column of pixel circuits 11 in the display area 101 other than the first sub-display area 1011, the present application further connects at least one column of pixel circuits 11 in the second sub-display area 1012 to at least one column of pixel circuits 11 in the display area 101 other than the second sub-display area 1012, thereby weakening the regional transistor characteristic differences caused by the length difference of the plurality of pixel circuits 11 in each column of the display area 101 after being connected in sequence, making the characteristics of the transistors with the same function in the display area 101 consistent, weakening the uneven display caused by the regional transistor characteristic differences between the first sub-display area 1011, the second sub-display area 1012 and the other display areas 101, and further improving the uniformity of the display picture of the display area 101.

[0044] Preferably, each column of pixel circuits 11 in the second sub-display area 1012 is connected to at least one column of pixel circuits 11 in the display area 101 other than the second sub-display area 1012. In other words, all columns of pixel circuits 11 in the second sub-display area 1012 are connected to at least one column of pixel circuits 11 in the display area 101 other than the second sub-display area 1012; specifically, the pixel circuits 11 at the ends of all columns of pixel circuits 11 in the second sub-display area 1012 are connected in sequence, and the end of the pixel circuits 11 in the column closest to the boundary line of the second sub-display area 1012 is connected to at least one column of pixel circuits 11 in the display area 101 other than the second sub-display area 1012. By connecting each column of pixel circuits 11 in the second sub-display area 1012 to at least one column of pixel circuits 11 in the display area 101 other than the second sub-display area 1012, the display effect of the second sub-display area 1012 is improved, the uneven display caused by the regional transistor characteristic differences between the second sub-display area 1012 and the other display areas 101 is weakened, and the uniformity of the display picture of the display area 101 is further improved.

[0045] More preferably, all column pixel circuits 11 of the first sub-display area 1011 are connected to at least one column pixel circuit 11 of the other display area 101 except the first sub-display area 1011, and all column pixel circuits 11 of the second sub-display area 1012 are connected to at least one column pixel circuit 11 of the other display area 101 except the second sub-display area 1012, which improves the display effect of the first sub-display area 1011 and the second sub-display area 1012, and weakens the display unevenness of the first sub-display area 1011, the second sub-display area 1012 and the other display area 101 due to the difference in the area-specific transistor characteristics, and the display screen of the display area 101 has good uniformity.

[0046] In an embodiment, at least one column pixel circuit 11 of the first sub-display area 1011 is connected to at least one column pixel circuit 11 of the second sub-display area 1012, so as to realize that at least one column pixel circuit 11 of the first sub-display area 1011 is connected to at least one column pixel circuit 11 of the other display area 101 except the first sub-display area 1011, and at least one column pixel circuit 11 of the second sub-display area 1012 is connected to at least one column pixel circuit 11 of the other display area 101 except the second sub-display area 1012.

[0047] Preferably, the pixel circuit 11 closest to the light-transmitting area 102 in the at least one column pixel circuit 11 of the first sub-display area 1011 is connected to the pixel circuit 11 closest to the light-transmitting area 102 in the at least one column pixel circuit 11 of the second sub-display area 1012.

[0048] More preferably, the pixel circuit 11 closest to the light-transmitting area 102 in all column pixel circuits 11 of the first sub-display area 1011 is sequentially connected to the pixel circuit 11 closest to the light-transmitting area 102 in all column pixel circuits 11 of the second sub-display area 1012.

[0049] In an embodiment, at least one column pixel circuit 11 of the first sub-display area 1011 is connected to at least one column pixel circuit 11 located on at least one side of the first sub-display area 1011 in the first direction X, so as to realize that at least one column pixel circuit 11 of the first sub-display area 1011 is connected to at least one column pixel circuit 11 of the other display area 101 except the first sub-display area 1011.

[0050] Preferably, the pixel circuit 11 closest to the light-transmitting area 102 in the at least one column pixel circuit 11 of the first sub-display area 1011 is connected to at least one column pixel circuit 11 located on at least one side of the first sub-display area 1011 in the first direction X.

[0051] Preferably, the pixel circuit 11 farthest from the light-transmitting region 102 in at least one column of pixel circuits 11 of the first sub-display region 1011 is connected to at least one column of pixel circuits 11 located on at least one side of the first sub-display region 1011 in the first direction X.

[0055] Preferably, the pixel circuit 11 closest to the light-transmitting region 102 in at least one column of pixel circuits 11 of the second sub-display region 1012 is connected to at least one column of pixel circuits 11 located on at least one side of the second sub-display region 1012 in the first direction X.

[0056] Preferably, the pixel circuit 11 farthest from the light-transmitting region 102 in at least one column of pixel circuits 11 of the second sub-display region 1012 is connected to at least one column of pixel circuits 11 located on at least one side of the second sub-display region 1012 in the first direction X.

[0057] More preferably, the pixel circuit 11 farthest from the light-transmitting region 102 in each column of pixel circuits 11 of the second sub-display region 1012 is connected to at least one column of pixel circuits 11 located on at least one side of the second sub-display region 1012 in the first direction X.
