[0049] It should be noted that Figure 2 An arrangement of the light-emitting devices 40 in the display panel is exemplarily shown in FIG. 1 .

[0052] The anode 401 of the second light emitting device 42 is connected to the anode 401 of the adjacent first light emitting device 41 emitting light of the same color.

[0053] Specifically, the light emitting device 40 includes a first color light emitting device 40a, a second color light emitting device 40b, and a third color light emitting device 40c, wherein the light emitting brightness of the first color light emitting device 40a is greater than the light emitting brightness of the second color light emitting device 40b, and the light emitting brightness of the second color light emitting device 40b is greater than the light emitting brightness of the third color light emitting device 40c.

[0054] The anode 401 of the second light emitting device 42 is connected to the anode 401 of the first light emitting device 41 of the same light emitting color as the adjacent one. That is, the anode 401 of the first color light emitting device 40a located in the peripheral wiring area NA is connected to the anode 401 of the first color light emitting device 40a located in the main display area AA adjacent to it; the anode 401 of the second color light emitting device 40b located in the peripheral wiring area NA is connected to the anode 401 of the second color light emitting device 40b located in the main display area AA adjacent to it; the anode 401 of the third color light emitting device 40c located in the peripheral wiring area NA is connected to the anode 401 of the third color light emitting device 40c located in the main display area AA adjacent to it.

Similarly, the anode 401 of the third color light emitting device 40c located in the peripheral wiring area NA is connected to the anode 401 of the third color light emitting device 40c located in the main display area AA adjacent thereto, so that the third color light emitting device 40c located in the peripheral wiring area NA and the third color light emitting device 40c located in the main display area AA adjacent thereto can be driven to emit light simultaneously through the same pixel driving circuit 21.

This disclosure will not be repeated here.

[0058] The light emitting device group 43 located in the peripheral display area NA includes at least one of the first color light emitting device 40a, the second color light emitting device 40b and the third color light emitting device 40c;

[0059] The peripheral wiring area NA includes two first wiring areas NA1 and two second wiring areas NA2. Along the first direction X, the two first wiring areas NA1 are respectively located on both sides of the main display area AA. Along the second direction Y, the two second wiring areas NA2 are respectively located on both sides of the main display area AA. The first direction X and the second direction Y intersect. Optionally, the first direction X and the second direction Y are perpendicular to each other.

[0060] The first wiring area NA1 includes at least one row of light emitting device groups 43 arranged along the second direction Y;

[0061] The second wiring area NA2 includes at least one row of light emitting device groups 43 arranged along the first direction X.

[0062] Specifically, the display panel includes a plurality of light emitting device groups 43, and the light emitting device group 43 includes at least one first color light emitting device 40a, at least one second color light emitting device 40b, and at least one third color light emitting device 40c.

[0063] It should be noted that Figure 2 and Figure 4 The light emitting device group 43 is exemplarily shown to include a first color light emitting device 40a, a second color light emitting device 40b and a third color light emitting device 40c, wherein the first color light emitting device 40a is a red light emitting device, the second color light emitting device 40b is a green light emitting device, and the third color light emitting device 40c is a blue light emitting device. In other embodiments of the present disclosure, the light emitting device group 43 may also include other numbers of first color light emitting devices 40a, second color light emitting devices 40b and third color light emitting devices 40c, and the first color light emitting devices 40a, second color light emitting devices 40b and third color light emitting devices 40c in the light emitting device group 43 may also be arranged in other ways, which will not be described in detail in the present disclosure.

[0064] The peripheral wiring area NA includes two first wiring areas NA1, and the two first wiring areas NA1 are respectively located on both sides of the main display area AA along the first direction X, and the first wiring area NA1 includes at least one column of light-emitting device groups 43 arranged along the second direction Y. The peripheral wiring area NA also includes two second wiring areas NA2, and the two second wiring areas NA2 are respectively located on both sides of the main display area AA along the second direction Y, and the second wiring area NA2 includes at least one row of light-emitting device groups 43 arranged along the first direction X. The light-emitting device group 43 located in the peripheral display area NA may include at least two of the first color light-emitting device 40a, the second color light-emitting device 40b, and the third color light-emitting device 40c. Optionally, the light-emitting device group 43 located in the peripheral display area NA may include the first color light-emitting device 40a, the second color light-emitting device 40b, and the third color light-emitting device 40c at the same time. Therefore, a light emitting device group 43 is arranged in the peripheral wiring area NA to surround the main display area AA, avoiding that only a single color light emitting device 40 is arranged on one side of the main display area AA in the peripheral wiring area NA, thereby effectively alleviating color deviation and being beneficial to improving the display effect of the peripheral wiring area NA.

[0065] It should be noted that in other embodiments of the present disclosure, the light-emitting device group 43 located in the peripheral display area NA may also include only one of the first color light-emitting device 40a, the second color light-emitting device 40b and the third color light-emitting device 40c.

[0066] For example, when the edge of the display panel has a greening problem when displaying, only the first color light emitting device 40a may be set in the corresponding light emitting device group 43 in the peripheral display area NA, that is, only the red light emitting device may be set in the corresponding light emitting device group 43 in the peripheral display area NA, thereby alleviating the greening problem at the edge of the display panel when displaying.

[0067] Continue to refer Figure 1-Figure 3 In some optional embodiments, the light emitting device group 43 includes a first light emitting device group 431, the first light emitting device group 431 includes a first sub-light emitting device group 441 and a second sub-light emitting device group 442 arranged along the first direction X, the first sub-light emitting device group 441 includes a first color light emitting device 40a and a second color light emitting device 40b arranged along the second direction Y, and the second sub-light emitting device group 442 includes a third color light emitting device 40c;

[0068] The light emitting device groups 43 located in the main display area AA and in the first wiring area NA1 are both first light emitting device groups 431 .

[0069] Specifically, the light-emitting device group 43 includes a first light-emitting device group 431, the first light-emitting device group 431 includes a first sub-light-emitting device group 441 and a second sub-light-emitting device group 442 arranged along the first direction X, the first sub-light-emitting device group 441 includes a first color light-emitting device 40a and a second color light-emitting device 40b arranged along the second direction Y, the second sub-light-emitting device group 442 includes a third color light-emitting device 40c, and the light-emitting device groups 43 located in the first wiring area NA1 are all first light-emitting device groups 431, so that in the first wiring area NA1, in a column of first sub-light-emitting device groups 441 arranged along the second direction Y, the first color light-emitting devices 40a and the second color light-emitting devices 40b are alternately arranged.

[0070] The first color light emitting device 40a is a red light emitting device, and the second color light emitting device 40b is a green light emitting device. The light emitting brightness of the first color light emitting device 40a and the second color light emitting device 40b is relatively high, so that the single arrangement of the first color light emitting device 40a at the edge will cause a more serious problem of red edges when displayed, and the single arrangement of the second color light emitting device 40b at the edge will cause a more serious problem of green edges when displayed, that is, the single arrangement of the first color light emitting device 40a or the single arrangement of the second color light emitting device 40b at the edge will cause color edge visual effect problems.

[0071] When, in the first wiring area NA1 located on one side of the main display area AA along the first direction X, the first sub-light emitting device group 441 in the first light emitting device group 431 is located on a side of the second sub-light emitting device group 442 away from the main display area AA, in a column of light emitting devices 40 arranged along the second direction Y in the first wiring area NA1 away from the outermost edge of the main display area AA, the first color light emitting devices 40a and the second color light emitting devices 40b are alternately arranged, thereby effectively alleviating the color edge visual effect problem.

[0072] Figure 5 yes Figure 1 An enlarged schematic diagram of the D portion of the display panel, see Figure 1 and Figure 5, when the second sub-light emitting device group 442 in the first light emitting device group 431 is located on the side of the first sub-light emitting device group 441 away from the main display area AA in the first wiring area NA1 located on the other side of the main display area AA along the first direction X, the light emitting devices 40 arranged along the second direction Y in a row located in the first wiring area NA1 away from the outermost edge of the main display area AA are all third color light emitting devices 40c, and the third color light emitting devices 40c are blue light emitting devices. Since the light emitting brightness of the third color light emitting device 40c is relatively low, the problem of blue edge during display caused by the light emitting devices 40 arranged along the first direction X in a row located in the first wiring area NA1 away from the outermost edge of the main display area AA are all third color light emitting devices 40c is relatively light, so the color edge visual effect problem is relatively light, and the impact on the display effect is relatively small.

[0073] Continue to refer Figure 1 and Figure 4 In some optional embodiments, the light emitting device group 43 located in the second wiring area NA2 is the first light emitting device group 431 .

[0074] Specifically, the light-emitting device group 43 located in the main display area AA is a first light-emitting device group 431. The first light-emitting device group 431 is set in the second wiring area NA2. The first light-emitting device group 431 includes a plurality of second light-emitting devices 42. The area where the second light-emitting devices 42 are set in the second wiring area NA2 can emit light, thereby reducing the dark area of ​​the second wiring area NA2, which is conducive to achieving a high PPI and a narrow frame of the display panel, and the anode 401 of the second light-emitting device 42 can block the wiring of the second wiring area NA2, thereby improving the display effect of the display panel.

[0075] Figure 6 yes Figure 1 Another enlarged schematic diagram of the C portion of the display panel, Figure 7 yes Figure 1 An enlarged schematic diagram of the E portion of the display panel, see Figure 1 , Figure 6 and Figure 7 In some optional embodiments, in the second wiring area NA2, in two adjacent first sub-light emitting device groups 441 along the first direction X, the first color light emitting devices 40a and the second color light emitting devices 40b are alternately arranged.

[0076] Specifically, the first color light emitting device 40a is a red light emitting device, and the second color light emitting device 40b is a green light emitting device. The light emitting brightness of the first color light emitting device 40a and the second color light emitting device 40b is relatively high, so that the single arrangement of the first color light emitting device 40a at the edge will cause a more serious problem of red edges when displayed, and the single arrangement of the second color light emitting device 40b at the edge will cause a more serious problem of green edges when displayed, that is, the single arrangement of the first color light emitting device 40a or the single arrangement of the second color light emitting device 40b at the edge will cause color edge visual effect problems.

[0077] In the second wiring area NA2, in two adjacent first sub-light-emitting device groups 441 along the first direction X, the first color light-emitting devices 40a and the second color light-emitting devices 40b are arranged alternately, so that in a row of light-emitting devices 40 arranged along the first direction X in the second wiring area NA2 away from the outermost edge of the main display area AA, the first color light-emitting devices 40a and the second color light-emitting devices 40b are alternately arranged, thereby avoiding the formation of a single arrangement of first color light-emitting devices 40a or a single arrangement of second color light-emitting devices 40b at the outermost edge of the second wiring area NA2 away from the main display area AA, effectively alleviating the color edge visual effect problem.

Since the light emitting brightness of the third color light emitting device 40c is relatively low, the light emitting devices 40 arranged along the first direction X in a row located in the second wiring area NA2 and away from the outermost edge of the main display area AA are all third color light emitting devices 40c, so the problem of blue edges during display is relatively light, thereby causing a relatively light color edge visual effect problem, and having little impact on the display effect.

The light emitting brightness of the first color light emitting device 40a and the second color light emitting device 40b is relatively high, so that the single arrangement of the first color light emitting device 40a at the edge will cause a more serious problem of red edges when displayed, and the single arrangement of the second color light emitting device 40b at the edge will cause a more serious problem of green edges when displayed, that is, the single arrangement of the first color light emitting device 40a or the single arrangement of the second color light emitting device 40b at the edge will cause color edge visual effect problems.

[0087] When the first color light emitting device 40a in the third light emitting device group 433 is located on a side of the third color light emitting device 40c away from the main display area AA in the first wiring area NA1 located on one side of the main display area AA along the first direction X, the first color light emitting devices 40a and the second color light emitting devices 40b are alternately arranged in the light emitting device 40 located in the first wiring area NA1 away from the outermost edge of the main display area AA, thereby avoiding the formation of a single arrangement of the first color light emitting devices 40a or a single arrangement of the second color light emitting devices 40b at the outermost edge of the first wiring area NA1 away from the main display area AA, effectively alleviating the color edge visual effect problem.

Since the light emitting brightness of the third color light emitting device 40c is relatively low, the problem of blue edge during display caused by the light emitting devices 40 arranged along the first direction X in a row located in the first wiring area NA1 away from the outermost edge of the main display area AA are all third color light emitting devices 40c is relatively light, so that the color edge visual effect problem is relatively light, and the impact on the display effect is relatively small.

The second color light-emitting device 40b is a green light-emitting device, so that the area of ​​the green light-emitting region in the first sub-routing area NA21 is increased, which is beneficial to alleviate the problem of red display in the first sub-routing area NA21 and improve the display effect.

[0110] The anode of the light emitting device 40 can also be connected to the anode of the adjacent first light emitting device 41 with the same light emitting color, thereby improving the problem of color fringing on the edge when the display panel displays a white picture.

The light emitting device groups 43 in the main display area AA are all the first light emitting device groups 431. The peripheral routing area NA includes two second routing areas NA2. Along the second direction Y, the two second routing areas NA2 are respectively located on both sides of the main display area AA. The second routing area NA2 includes a first sub-routing area NA21. A row of first light-emitting devices 41 close to the first sub-routing area NA21 in the main display area AA are second color light-emitting devices 40b, that is, a row of first light-emitting devices 41 close to the first sub-routing area NA21 in the main display area AA are green light-emitting devices, and the edge of the display panel appears green when displaying. A row of light-emitting device groups 43 is set in the first sub-routing area NA21, and each light-emitting device group 43 in the first sub-routing area NA21 includes only one light-emitting device 40, and the light-emitting devices 40 are all first color light-emitting devices 40a, that is, the light-emitting devices 40 are all red light-emitting devices, so that the problem of green edges appearing when the display panel displays can be improved.

[0112] Optionally, the size of the first color light emitting device 40a in the first sub-alignment area NA21 may be set according to a balance effect to be achieved at the edge of the display panel when displaying, which will not be elaborated in the present disclosure.

[0113] Similarly, reference Figure 1 and Fig.19 , Fig.19 yes Figure 1Another enlarged schematic diagram of the E portion of the display panel, the second routing area NA2 includes a second sub-routing area NA22, and a row of first light-emitting devices 41 near the second sub-routing area NA22 in the main display area AA are first color light-emitting devices 40a, that is, a row of first light-emitting devices 41 near the second sub-routing area NA22 in the main display area AA are red light-emitting devices, and the display panel has a reddish edge problem when displaying. A row of light-emitting device groups 43 is set in the second sub-routing area NA22, and each light-emitting device group 43 in the second sub-routing area NA22 includes only one light-emitting device 40, and the light-emitting devices 40 are all second color light-emitting devices 40b, that is, the light-emitting devices 40 are all green light-emitting devices, thereby improving the problem of reddish edges when displaying the display panel.

[0114] Optionally, the size of the second color light emitting device 40b in the second sub-alignment area NA22 may be set according to a balance effect to be achieved at the edge of the display panel when displaying, which will not be elaborated in the present disclosure. Fig. 20 yes Figure 1 Another enlarged schematic diagram of the A portion of the display panel, see Figure 1 and Fig. 20 In some optional embodiments, a vertical projection area of ​​the second light emitting device 42 on the plane where the base substrate 10 is located is greater than a vertical projection area of ​​the first light emitting device 41 on the plane where the base substrate 10 is located.

[0115] Specifically, a second light-emitting device 42 is provided in the peripheral wiring area NA, and the anode 401 of the second light-emitting device 42 is connected to the anode 401 of the first light-emitting device 41 adjacent to it, so that the pixel driving circuit 21 electrically connected to the anode 401 of the first light-emitting device 41 adjacent to it can simultaneously drive the second light-emitting device 42 and the first light-emitting device 41 adjacent to it to emit light, thereby realizing the light emission of the second light-emitting device 42 located in the peripheral wiring area NA, and the vertical projection area of ​​the second light-emitting device 42 on the plane where the substrate 10 is located is larger than the vertical projection area of ​​the first light-emitting device 41 on the plane where the substrate 10 is located, that is, the size of the second light-emitting device 42 is larger than the size of the first light-emitting device 41, that is, the size of the second light-emitting device 42 in the peripheral wiring area NA is larger, which further reduces the dark area of ​​the peripheral wiring area NA, which is conducive to realizing a narrow frame of the display panel and improving the display effect of the display panel.

[0116] It should be noted that the vertical projection area of ​​the second light-emitting device 42 on the plane where the substrate 10 is located is larger than the vertical projection area of ​​the first light-emitting device 41 on the plane where the substrate 10 is located, which means that among the second light-emitting device 42 and the first light-emitting device 41 of the same color, the vertical projection area of ​​the second light-emitting device 42 on the plane where the substrate 10 is located is larger than the vertical projection area of ​​the first light-emitting device 41 on the plane where the substrate 10 is located.

[0117] Fig.21 yes Figure 1 Another enlarged schematic diagram of the A portion of the display panel, see Figure 1 and Fig.21 In some optional embodiments, the distance between two adjacent second light-emitting devices 42 is greater than the distance between two adjacent first light-emitting devices 41 .

[0118] Specifically, a second light-emitting device 42 is provided in the peripheral wiring area NA, and the anode 401 of the second light-emitting device 42 is connected to the anode 401 of the first light-emitting device 41 adjacent to it, so that the pixel driving circuit 21 electrically connected to the anode 401 of the first light-emitting device 41 adjacent to it can simultaneously drive the second light-emitting device 42 and the first light-emitting device 41 adjacent to it to emit light, thereby realizing the light emission of the second light-emitting device 42 located in the peripheral wiring area NA, and the spacing between two adjacent second light-emitting devices 42 is greater than the spacing between two adjacent first light-emitting devices 41, that is, the size of the second light-emitting device 42 is greater than the size of the first light-emitting device 41, that is, the spacing between two adjacent second light-emitting devices 42 in the peripheral wiring area NA is larger, so that the width of the area for setting the second light-emitting device 42 in the peripheral wiring area NA is larger, and the width of the area for light emission in the corresponding peripheral wiring area NA is increased, which is conducive to realizing a narrow frame of the display panel and improving the display effect of the display panel.

[0119] Exemplary, reference Fig.21 , the spacing between the adjacent second color light emitting devices 40b and the third color light emitting devices 40c in the first wiring area NA1 is L1, and the spacing between the adjacent second color light emitting devices 40b and the third color light emitting devices 40c in the main display area AA is L2, where L1 is greater than L2. It should be noted that, Fig.21 It is exemplarily shown that the spacing between two adjacent second light-emitting devices 42 along the first direction X is greater than the spacing between two adjacent first light-emitting devices 41 along the first direction X. In other embodiments of the present disclosure, the spacing between two adjacent second light-emitting devices 42 along the second direction Y is greater than the spacing between two adjacent first light-emitting devices 41 along the second direction Y, which is not further described in the present disclosure.

[0121] The vertical projection pattern of the anode connecting portion 404 on the plane where the base substrate 10 is located is a linear structure, and the anode connecting portion 404 and the anode 401 not connected thereto are insulated from each other.

[0122] Specifically, the anode 401 of the second light-emitting device 42 is connected to the anode 401 of the adjacent first light-emitting device 41 through the anode connecting portion 404, thereby realizing that the anode 401 of the second light-emitting device 42 is connected to the anode 401 of the adjacent first light-emitting device 41, and the anode connecting portion 404 and the anode 401 are located in the same film layer, that is, the anode connecting portion 404 and the anode 401 are formed using the same material in the same process step, which is beneficial to reducing the process flow and reducing production costs.

[0123] The vertical projection pattern of the anode connecting portion 404 on the plane where the base substrate 10 is located is a linear structure, which is conducive to the mutual insulation between the anode connecting portion 404 and the anode 401 not connected to it, that is, the anode connecting portion 404 and the anodes 401 other than the anode 401 connected to it are insulated from each other, thereby realizing the connection of the anode 401 of the second light-emitting device 42 and the anode 401 of the adjacent first light-emitting device 41 through the anode connecting portion 404, and at the same time, avoiding the anodes 401 of the two light-emitting devices 40 from being connected to the anodes 401 of other light-emitting devices 40, thereby avoiding affecting the display effect.

[0124] It should be noted that the vertical projection pattern of the anode connecting portion 404 on the plane where the base substrate 10 is located can be a straight line, a curve, or other linear structures. It can be set according to the arrangement of the light-emitting device 40. It only needs to ensure that the anode connecting portion 404 and the anode 401 that is not connected to it are insulated from each other. The present disclosure will not elaborate on it here.
