[0048] Please refer to Figures 1-2 In the related technical solutions, the display panel includes a display area and a non-display area NAA, wherein the non-display area NAA is arranged around the outside of the display area, and the display area and the non-display area NAA have a first boundary 11 therebetween. The display area includes a first display area AA1 and a second display area AA2, and the light transmittance of the second display area AA2 is different from that of the first display area AA1. For example, the light transmittance of the second display area AA2 can be greater than that of the first display area AA1, and the front camera is arranged below the second display area AA2 to achieve better shooting effect.
[0049] As Figure 1 shown, the first display area AA1 and the second display area AA2 can be arranged adjacent to the non-display area NAA, and the first display area AA1 half-encloses the second display area AA2. It can be understood that the first display area AA1 half-encloses the second display area AA2 means that the first display area AA1 encloses part of the second display area AA2, and the other part is exposed outside the first display area AA1 and is not enclosed by the first display area AA1. For example, as Figure 1As shown in FIG. 1, the display panel and the second display area AA2 are both square in shape, and the second display area AA2 is located in the middle region of the upper end of the display panel. In the display panel, the first display area AA1 semi-surrounds the second display area AA2, which means that the first display area AA1 surrounds the left side, the right side and the lower side between the left side and the right side of the second display area AA2. The upper side of the second display area AA2 is the first boundary 11 between the display area and the non-display area NAA, which is not surrounded by the first display area AA1. In the display panel, the first display area AA1 semi-surrounds the second display area AA2, which means that the first display area AA1 surrounds the side of the second display area AA2 other than the first boundary 11.
[0050] As shown in FIG. 2, the first display area AA1 can also fully surround the second display area AA2, and the first display area AA1 is adjacent to the non-display area NAA. It can be understood that the first display area AA1 fully surrounds the second display area AA2, which means that the first display area AA1 surrounds the outer peripheral side of the second display area AA2. At this time, the second display area AA2 is not directly adjacent to the first boundary 11 between the display area and the non-display area NAA. Figure 2
[0051] The light transmittance of the second display area AA2 is greater than that of the first display area AA1, which can be achieved by reducing the number of pixel driving circuits in the second display area AA2. For example, one pixel driving circuit can be used to drive one sub-pixel in the first display area AA1, and one pixel driving circuit can be used to drive multiple sub-pixels (a plurality of sub-pixels driven by the same pixel driving circuit form a sub-pixel group) in the second display area AA2. In this way, compared with the first display area AA1, the number of pixel driving circuits in the second display area AA2 is smaller, thereby reducing the shielding of light by the pixel driving circuits in the second display area AA2, which is conducive to improving the imaging quality of the front camera arranged below the second display area AA2.
[0052] However, since the outermost sub-pixels need to be edge compensated when the display panel is normally displayed, the above scheme may cause the brightness of some sub-pixels in the sub-pixel group closest to the first boundary 11 in the second display area AA2 to decrease, thereby forming a dark line 12 and affecting the normal display effect of the second display area AA2.
[0053] In view of this, this application aims to provide a display panel and display device, which, by having the light-emitting area of the sub-pixels near the first boundary in the sub-pixel group near the first boundary in the second display area be different from the light-emitting area of the sub-pixels not near the first boundary, or by having the pixel aperture size of the sub-pixels near the first boundary be different from the pixel aperture size of the sub-pixels not near the first boundary, makes the brightness of each sub-pixel in the sub-pixel group tend to be consistent under the same voltage, thereby helping to eliminate dark lines and improve the display effect of the second display area.
[0054] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are some embodiments of this application, but not all embodiments.
[0055] Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without inventive effort are within the scope of protection of this application. Unless otherwise specified, the following embodiments and features can be combined with each other.
[0056] Please refer to Figures 3-6 This embodiment provides a display panel including a display area and a non-display area NAA. The display area has a first display area AA1 and a second display area AA2. The light transmittance of the second display area AA2 is different from that of the first display area AA1. A first boundary 11 is provided between the display area and the non-display area NAA.
[0057] Specifically, in this embodiment, the light transmittance of the second display area AA2 is greater than that of the first display area AA1. The second display area AA2 can be rectangular, circular, teardrop-shaped, etc. For ease of description, this embodiment uses a rectangular second display area AA2 as an example. The display panel can be as follows: Figure 3 The structure shown can also be as follows: Figure 5 The structure shown. Among them, Figure 3 The structure shown is the same as the one described above. Figure 1 The structures shown are the same. Figure 5 The structure shown is the same as the one described above. Figure 2 The structure shown is the same, and will not be described again in this embodiment.
[0058] The display panel also includes a substrate and a pixel limiting layer disposed on the substrate. The pixel limiting layer has a plurality of pixel openings 101, and a sub-pixel is disposed in each pixel opening 101. That is, each pixel opening 101 can be filled with a sub-pixel of a color.
[0059] The sub-pixel includes a first electrode, an organic light-emitting layer and a second electrode on the substrate. The pixel defining layer surrounds the pixel opening 101 on the first electrode. The organic light-emitting layer is arranged in the pixel opening 101. The second electrode is arranged on the organic light-emitting layer. As shown in Figure 4 and Figure 6 The first display area AA1 and the second display area AA2 each include a plurality of sub-pixels of different colors. For example, the first display area AA1 and the second display area AA2 each include a plurality of red sub-pixels 110, blue sub-pixels 120 and green sub-pixels 130. In the second display area AA2, at least a plurality of sub-pixels of the same color are sequentially and synchronously driven by the same pixel driving circuit, forming a sub-pixel group 20 (as shown in Figure 4 and Figure 6 The dashed box in Figure 4 and Figure 6 is a sub-pixel group 20. In and
[0060] , four green sub-pixels 130 sequentially and synchronously driven by the same pixel driving circuit are taken as an example. Figure 4 Figure 6 In the embodiment, the first electrodes of adjacent sub-pixels in the same sub-pixel group 20 are electrically connected by electrode traces 102. The electrode traces 102 are straight lines (as shown in
[0061] The pixel driving circuit of the same sub-pixel group is electrically connected to the first electrode of one sub-pixel in the same sub-pixel group by a connection line (not shown in the figure). The connection line can also be a straight line or a curved line.
[0062] Further, in the second display area AA2, the orthographic projection of the pixel opening 101 on the substrate is circular or square. Still further, the shape of the pixel opening 101 in the first display area AA1 is different from the shape of the pixel opening 101 in the second display area AA2.
[0063] For example, as shown in Figure 4 and Figure 6 , in the embodiment, the pixel opening 101 in the first display area AA1 is square, and the pixel opening 101 in the second display area AA2 is circular.
[0064] In one sub-pixel group 20 adjacent to the first boundary 11, the light-emitting area of the sub-pixel adjacent to the first boundary 11 is different from the light-emitting area of the sub-pixel not adjacent to the first boundary 11, or the size of the pixel opening 101 of the sub-pixel adjacent to the first boundary 11 is different from the size of the pixel opening 101 of the sub-pixel not adjacent to the first boundary 11.
[0065] For example, as shown in Figure 4As shown, in the sub-pixel group 20 adjacent to the first boundary 11, the light-emitting area of the green sub-pixel 130 adjacent to the first boundary 11 is smaller than the light-emitting area of the green sub-pixel 130 not adjacent to the first boundary 11; the pixel opening 101 size of the green sub-pixel 130 adjacent to the first boundary 11 is smaller than the pixel opening 101 size of the green sub-pixel 130 not adjacent to the first boundary 11.
[0066] For example, such as Figure 6 As shown, in the sub-pixel group 20 adjacent to the first boundary 11, the light-emitting area of the green sub-pixel 130 adjacent to the first boundary 11 is larger than the light-emitting area of the green sub-pixel 130 not adjacent to the first boundary 11; the pixel opening 101 size of the green sub-pixel 130 adjacent to the first boundary 11 is larger than the pixel opening 101 size of the green sub-pixel 130 not adjacent to the first boundary 11.
[0067] With the above settings, this application can make the brightness of each sub-pixel in the sub-pixel group 20 tend to be consistent under the same voltage, which helps to eliminate dark lines and improve the display effect of the second display area AA2.
[0068] In one possible implementation, such as Figure 3 and Figure 4 As shown, when the second display area AA2 is adjacent to the non-display area NAA, in a sub-pixel group 20 near the first boundary 11, the light-emitting area of the sub-pixels not near the first boundary 11 is 105-150% of the light-emitting area of the sub-pixels near the first boundary 11. Alternatively, the pixel aperture 101 size of the sub-pixels near the first boundary 11 is 80-95% of the pixel aperture 101 size of the sub-pixels not near the first boundary 11.
[0069] Preferably, in a sub-pixel group 20 adjacent to the first boundary 11, the light-emitting area of the sub-pixel not adjacent to the first boundary 11 is 110-130% of the light-emitting area of the sub-pixel adjacent to the first boundary 11; or the pixel opening 101 size of the sub-pixel adjacent to the first boundary 11 is 85-95% of the pixel opening 101 size of the sub-pixel not adjacent to the first boundary 11.
[0070] More preferably, in a sub-pixel group 20 adjacent to the first boundary 11, the light-emitting area of the sub-pixel not adjacent to the first boundary 11 is 110-120% of the light-emitting area of the sub-pixel adjacent to the first boundary 11; or the pixel opening 101 size of the sub-pixel adjacent to the first boundary 11 is 85-90% of the pixel opening 101 size of the sub-pixel not adjacent to the first boundary 11.
[0071] That is, when the second display area AA2 is immediately adjacent to the non-display area NAA, in the sub-pixel group 20, the aperture ratio of the sub-pixel adjacent to the first boundary 11 is less than the aperture ratio of the sub-pixel not adjacent to the first boundary 11.
[0072] Through the above arrangement, the volume of the sub-pixel adjacent to the first boundary 11 is increased, and the resistance is reduced. Under the same voltage, the brightness of each sub-pixel in the sub-pixel group 20 tends to be consistent, thereby facilitating the elimination of dark lines and improving the display effect of the second display area AA2.
[0073] In another possible implementation, as shown in FIGS. 1C and 1D, when the second display area AA2 is not immediately adjacent to the non-display area NAA, in the sub-pixel group 20 adjacent to the first boundary 11, the light-emitting area of the sub-pixel adjacent to the first boundary 11 is 105-150% of the light-emitting area of the sub-pixel not adjacent to the first boundary 11; or the size of the pixel opening 101 of the sub-pixel adjacent to the first boundary 11 is 105-150% of the size of the pixel opening 101 of the sub-pixel not adjacent to the first boundary 11. Figure 5 Figure 6 In another possible implementation, as shown in FIGS. 1C and 1D, when the second display area AA2 is not immediately adjacent to the non-display area NAA, in the sub-pixel group 20 adjacent to the first boundary 11, the light-emitting area of the sub-pixel adjacent to the first boundary 11 is 105-150% of the light-emitting area of the sub-pixel not adjacent to the first boundary 11; or the size of the pixel opening 101 of the sub-pixel adjacent to the first boundary 11 is 105-150% of the size of the pixel opening 101 of the sub-pixel not adjacent to the first boundary 11.
[0074] In another possible implementation, as shown in FIGS. 1C and 1D, when the second display area AA2 is not immediately adjacent to the non-display area NAA, in the sub-pixel group 20 adjacent to the first boundary 11, the light-emitting area of the sub-pixel adjacent to the first boundary 11 is 105-150% of the light-emitting area of the sub-pixel not adjacent to the first boundary 11; or the size of the pixel opening 101 of the sub-pixel adjacent to the first boundary 11 is 105-150% of the size of the pixel opening 101 of the sub-pixel not adjacent to the first boundary 11.
[0075] In another possible implementation, as shown in FIGS. 1C and 1D, when the second display area AA2 is not immediately adjacent to the non-display area NAA, in the sub-pixel group 20 adjacent to the first boundary 11, the light-emitting area of the sub-pixel adjacent to the first boundary 11 is 105-150% of the light-emitting area of the sub-pixel not adjacent to the first boundary 11; or the size of the pixel opening 101 of the sub-pixel adjacent to the first boundary 11 is 105-150% of the size of the pixel opening 101 of the sub-pixel not adjacent to the first boundary 11.
[0076] That is, when the second display area AA2 is not immediately adjacent to the non-display area NAA, in the sub-pixel group 20, the aperture ratio of the sub-pixel adjacent to the first boundary 11 is greater than the aperture ratio of the sub-pixel not adjacent to the first boundary 11.
[0077] Through the above arrangement, the volume of the sub-pixel adjacent to the first boundary 11 is increased, and the resistance is reduced. Under the same voltage, the brightness of each sub-pixel in the sub-pixel group 20 tends to be consistent, thereby facilitating the elimination of dark lines and improving the display effect of the second display area AA2.
[0078] In some possible implementations, in the second display area AA2 of the present embodiment, the sub-pixel groups 20 are divided into red sub-pixel groups, blue sub-pixel groups, and green sub-pixel groups according to the light-emitting colors.Figure 4 and Figure 6 The green sub-pixel group is only indicated by a dashed box in FIG. 6). The sub-pixel group 20 includes n sub-pixels of the same color, where n is a natural number greater than or equal to 2.
[0079] Preferably, n is a natural number, and 2<=n<=8. For example, as shown in FIG. 6, the sub-pixel group 20 includes four sub-pixels of the same color. Figure 4 and Figure 6 Preferably, n is a natural number, and 2<=n<=8. For example, as shown in FIG. 6, the sub-pixel group 20 includes four sub-pixels of the same color.
[0080] The second display area AA2 includes a plurality of second pixel units arranged in an array, and each second pixel unit includes at least one red sub-pixel group, at least one blue sub-pixel group, and at least one green sub-pixel group.
[0081] Preferably, in the same second pixel unit, the number of red sub-pixels 110 in the red sub-pixel group is the same as or different from the number of blue sub-pixels 120 in the blue sub-pixel group; and / or the number of red sub-pixels 110 in the red sub-pixel group is the same as or different from the number of green sub-pixels 130 in the green sub-pixel group; and / or the number of blue sub-pixels 120 in the blue sub-pixel group is the same as or different from the number of green sub-pixels 130 in the green sub-pixel group.
[0082] That is, in the embodiment, the number of red sub-pixels 110, blue sub-pixels 120, and green sub-pixels 130 in one second pixel unit can be the same or different; for example, one second pixel unit can include three red sub-pixels 110, two blue sub-pixels 120, and four green sub-pixels 130; or one second pixel unit can include four red sub-pixels 110, four blue sub-pixels 120, and four green sub-pixels 130.
[0083] Further, the second pixel units in the second display area AA2 are arranged in an array along the first direction X and the second direction Y.
