Detailed Description
Referring to fig. 1-2, in a related art, a display panel includes a display area and a non-display area NAA, wherein the non-display area NAA surrounds an outer side of the display area, and a first boundary 11 is formed between the display area and the non-display area NAA. The display region includes a first display region AA1 and a second display region AA2, and the light transmittance of the second display region AA2 is different from the light transmittance of the first display region AA 1. For example, the light transmittance of the second display area AA2 may be greater than that of the first display area AA1, and the front camera is disposed below the second display area AA2 to achieve a better photographing effect.
As shown in fig. 1, the first display area AA1 and the second display area AA2 may both be disposed adjacent to the non-display area NAA, and the first display area AA1 half-surrounds the second display area AA 2. It is understood that the first display area AA1 semi-surrounding the second display area AA2 means that the first display area AA1 surrounds a portion of the second display area AA2, and another portion is exposed outside the first display area AA1 and is not surrounded by the first display area AA 1. For example, as shown in fig. 1, the display panel and the second display area AA2 are both square in shape, the second display area AA2 is located in the middle area of the upper end of the display panel, in the display panel, the first display area AA1 half-surrounds the second display area AA2 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, and 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 AA 1. In the display panel, the first display area AA1 semi-surrounding the second display area AA2 means that the first display area AA1 surrounds the other sides of the second display area AA2 except the first boundary 11.
As shown in fig. 2, the first display area AA1 may also entirely surround the second display area AA2, and the first display area AA1 is disposed adjacent to the non-display area NAA. It is understood that the first display area AA1 entirely surrounds the second display area AA2 means that the first display area AA1 surrounds an outer circumferential side of the second display area AA2, and 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.
The light transmittance of the second display area AA2 is greater than that of the first display area AA1, which may be realized by reducing the number of pixel driving circuits in the second display area AA 2. For example, one pixel driving circuit may drive one sub-pixel in the first display area AA1, and one pixel driving circuit may drive a plurality of sub-pixels (a plurality of sub-pixels driven by the same pixel driving circuit form a sub-pixel group) in the second display area AA 2. In this way, compared with the first display area AA1, the number of the pixel driving circuits in the second display area AA2 is smaller, so that the shielding of the pixel driving circuits in the second display area AA2 from light is reduced, which is beneficial to improving the imaging quality of the front camera disposed below the second display area AA 2.
However, when the display panel normally displays, the sub-pixels at the outermost circle need to be edge compensated, and by adopting the above scheme, the luminance of some sub-pixels in the sub-pixel group closest to the first boundary 11 in the second display area AA2 may be reduced, so that the dark line 12 is formed, and the normal display effect of the second display area AA2 is affected.
In view of the above, the present application aims to provide a display panel and a display device, in a second display area, in a sub-pixel group adjacent to a first boundary, a light emitting area of a sub-pixel adjacent to the first boundary is different from a light emitting area of a sub-pixel not adjacent to the first boundary, or a pixel opening size of a sub-pixel adjacent to the first boundary is different from a pixel opening size of a sub-pixel not adjacent to the first boundary, so that under the same voltage, luminance of each sub-pixel in the sub-pixel group tends to be uniform, thereby facilitating elimination of a dark line and improving a display effect of the second display area.
In order to make the objects, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are some embodiments of the present application, but not all embodiments.
All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application. The embodiments described below and the features of the embodiments can be combined with each other without conflict.
Referring to fig. 3 to 6, the present embodiment provides a display panel including a display area and a non-display area NAA, wherein the display area has a first display area AA1 and a second display area AA2, a light transmittance of the second display area AA2 is different from a light transmittance of the first display area AA1, and a first boundary 11 is formed between the display area and the non-display area NAA.
Specifically, in the embodiment, the light transmittance of the second display area AA2 is greater than that of the first display area AA1, and the second display area AA2 may be rectangular, circular, or drop-shaped, and for convenience of description, the embodiment takes the case where the second display area AA2 is rectangular as an example. The display panel may have a structure as shown in fig. 3 or may have a structure as shown in fig. 5. The structure shown in fig. 3 is the same as the structure shown in fig. 1, and the structure shown in fig. 5 is the same as the structure shown in fig. 2, which are not described again in this embodiment.
The display panel further comprises a substrate and a pixel defining layer arranged on the substrate, wherein a plurality of pixel openings 101 are arranged on the pixel defining layer, and one sub-pixel is arranged in each pixel opening 101, that is, each pixel opening 101 can be filled with one color sub-pixel.
The sub-pixel includes a first electrode, an organic light emitting layer, and a second electrode on the substrate, the pixel defining layer is enclosed on the first electrode to form a pixel opening 101, the organic light emitting layer is disposed in the pixel opening 101, and the second electrode is disposed on the organic light emitting layer. As shown in fig. 4 and 6, each of the first and second display areas AA1 and AA2 includes a plurality of sub-pixels having different colors; for example, the first display area AA1 and the second display area AA2 each include a plurality of red subpixels 110, blue subpixels 120, and green subpixels 130. In the second display area AA2, a plurality of sub-pixels having at least the same color are sequentially and electrically connected and synchronously driven by the same pixel driving circuit to form a sub-pixel group 20 (as shown by a dotted line frame in fig. 4 and 6, one sub-pixel group 20 is illustrated, and four green sub-pixels 130 sequentially and electrically connected and synchronously driven by the same pixel driving circuit are illustrated in fig. 4 and 6).
In this embodiment, the first electrodes of adjacent sub-pixels in the same sub-pixel group 20 are electrically connected through the electrode trace 102; the electrode trace 102 is either straight (as shown in fig. 4 and 6) or curved.
The pixel driving circuit of the same sub-pixel group is electrically connected with the first electrode of one sub-pixel in the same sub-pixel group through a connecting line (not shown in the figure); the connecting line can also be a straight line or a curved line.
Further, in the second display area AA2, an orthogonal projection of the pixel opening 101 on the substrate has a circular or square shape. Further, the shape of the pixel opening 101 located in the first display area AA1 is different from the shape of the pixel opening 101 located in the second display area AA 2.
For example, as shown in fig. 4 and 6, in the present embodiment, the pixel opening 101 located in the first display area AA1 has a square shape, and the pixel opening 101 located in the second display area AA2 has a circular shape.
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.
For example, as shown in fig. 4, 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 size of the pixel aperture 101 of the green sub-pixel 130 adjacent to the first boundary 11 is smaller than the size of the pixel aperture 101 of the green sub-pixel 130 not adjacent to the first boundary 11.
As another example, as shown in fig. 6, 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 size of the pixel aperture 101 of the green sub-pixel 130 adjacent to the first boundary 11 is larger than the size of the pixel aperture 101 of the green sub-pixel 130 not adjacent to the first boundary 11.
Through the arrangement, the brightness of each sub-pixel in the sub-pixel group 20 tends to be consistent under the same voltage, so that the dark line is eliminated, and the display effect of the second display area AA2 is improved.
In one possible embodiment, as shown in fig. 3 and 4, when the second display area AA2 is adjacent to the non-display area NAA, in one 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 105-150% of the light emitting area of the sub-pixel adjacent to the first boundary 11. Alternatively, the size of the pixel aperture 101 of the sub-pixel adjacent to the first boundary 11 is 80-95% of the size of the pixel aperture 101 of the sub-pixel not adjacent to the first boundary 11.
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 size of the pixel aperture 101 of the sub-pixel adjacent to the first boundary 11 is not 85-95% of the size of the pixel aperture 101 of the sub-pixel adjacent to the first boundary 11.
It is further preferable that, 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 size of the pixel aperture 101 of the sub-pixel adjacent to the first boundary 11 is not 85-90% of the size of the pixel aperture 101 of the sub-pixel adjacent to the first boundary 11.
That is, when the second display area AA2 is adjacent to the non-display area NAA, the aperture ratio of the sub-pixels adjacent to the first boundary 11 is smaller than the aperture ratio of the sub-pixels not adjacent to the first boundary 11 in the sub-pixel group 20.
Through the arrangement, the volume of the sub-pixels not adjacent to the first boundary 11 is increased, the resistance is reduced, and the brightness of each sub-pixel in the sub-pixel group 20 tends to be consistent under the same voltage, so that the dark line is eliminated, and the display effect of the second display area AA2 is improved.
In another possible embodiment, as shown in fig. 5 and 6, when the second display area AA2 is not immediately adjacent to the non-display area NAA, 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 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 not 105-150% of the size of the pixel opening 101 of the sub-pixel adjacent to the first boundary 11.
