In view of the pixel arrangement of the semi-transparent area in the prior art, when the photosensitive elements such as a camera are arranged below the display panel, the phenomenon of starburst exists in photographing. The inventor researches the prior art to find that in the prior art, in order to improve the light transmittance of the semi-transparent area, a white sub-pixel is usually arranged in the semi-transparent area, but the white sub-pixels are all regularly arranged at equal intervals, a non-opening area surrounding an opening area of the white sub-pixel is a straight line segment, and when external light passes through the edge of the opening area of the white sub-pixel, the light is obviously diffracted, so that the starburst phenomenon is caused.

In fig. 1, the display panel 100 includes a display area AA and a non-display area BB at least partially surrounding the display area AA, the display area AA includes a first display area AA1, the first display area AA1 includes a first subpixel P1, the first subpixel P1 includes a white subpixel W and a color subpixel Y, the display panel 100 includes a substrate base 00, a front projection of the color subpixel Y on a plane of the substrate base 00 includes a first curved edge 1, a front projection of the white subpixel W on the plane of the substrate base 00 includes a second curved edge 2, and the first curved edge 1 at least partially overlaps the second curved edge 2.

It should be noted that fig. 1 only illustrates the display panel 100 as a rectangular display panel 100, in some other embodiments of the present application, the display panel 100 may also be embodied in other shapes, such as a circle, an ellipse, or a special-shaped structure, and the size of the first display area AA1 is also only illustrated and does not represent an actual size. Fig. 1 shows only one position of the first display area AA1 on the display panel 100, in some other embodiments of the present application, the first display area AA1 may be disposed at other positions of the display panel 100, and the number of the first display areas AA1 may also be two or more. The display panel 100 in the present invention may be a liquid crystal display panel, and may also be an organic self-emitting display panel, which is not limited herein.

In addition, fig. 1 also shows a second display area AA2 that completely surrounds the first display area AA1, and in some other embodiments of the present application, the second display area AA2 may also partially surround the first display area AA1, which is not specifically limited in this application.

Fig. 2 and 3 only show a portion of the first subpixel P1 in the first display area AA1 and the second subpixel P2 in the second display area AA2, respectively, and do not represent the actual number and arrangement of the first subpixel P1 and the second subpixel P2 included in the first display area AA1 and the second display area AA2, and fig. 2 and 3 do not represent the actual size of the subpixel P, and are only schematic. It can be understood that the density of the color sub-pixels in the first display area AA1 is less than that of the color sub-pixels in the second display area AA2, so that the first display area AA1 can perform the image display function and also perform the light sensing function, and has a higher transmittance during the light sensing process, thereby facilitating to improve the light sensing performance of the first display area AA 1.

Fig. 2 and 3 schematically show that the color sub-pixels Y included in different first sub-pixels P1 may be a red sub-pixel R, a green sub-pixel G, and a blue sub-pixel B, fig. 2 shows that the color sub-pixels Y are circular, fig. 3 shows that the color sub-pixels Y are elliptical, of course, the color sub-pixels Y have a first curved edge 1 at the outer edge of the front projection of the plane of the substrate 00, fig. 2 and 3 show that the number of the color sub-pixels Y at the first sub-pixel P1 is only 1, of course, the number of the color sub-pixels Y at the first sub-pixel P1 may also be 2 or 3, and is not specifically limited, fig. 2 shows that the first curved edge 1 completely overlaps the second curved edge 2, that the white sub-pixel W surrounds the color sub-pixel Y in fig. 2, fig. 3 shows that the first curved edge 1 partially overlaps the second curved edge 2, i.e. the white sub-pixel W partially surrounds the color sub-pixel Y in fig. 3.

The white sub-pixel W in fig. 4 has an elliptical shape, while the position of the color sub-pixel Y in the different first sub-pixel P1 in fig. 4 is different; the shape of the white sub-pixel W in fig. 5 is irregular, and the embodiment in fig. 5 can increase the area of the white sub-pixel W as much as possible and improve the light transmittance; the embodiment in fig. 6 shows that the color sub-pixel Y is semicircular, and of course, the first curved edge 1 and the second curved edge 2 in fig. 4 to 6 completely overlap, wherein the white sub-pixel W in fig. 4 and 5 completely surrounds the color sub-pixel Y, and the white sub-pixel W in fig. 6 partially surrounds the color sub-pixel Y.

Of course, fig. 2 and 3 also show the black matrix BM for preventing color mixing between the color sub-pixels Y, and the signal lines may be disposed in the light-shielding region of the black matrix BM without affecting the aperture ratio of the color sub-pixels Y. It should be noted that the color sub-pixel Y includes an open region KK and a non-open region NK surrounding the open region KK, and in the present invention, the first curved edge 1 of the color sub-pixel Y refers to the edge of the non-open region NK, and the second curved edge 2 of the white sub-pixel W refers to the edge of the open region.

It is understood that the starburst phenomenon occurs in the prior art because of diffraction of light, and when the edge of the opening area of the sub-pixel is a straight line segment, when light passes through the straight line segment, diffraction spots are light and dark interval stripes which are staggered transversely and longitudinally to form a typical cross diffraction grating structure, and the more regular the opening area edge of the sub-pixel, the more obvious the diffraction effect, the pixel in the prior art is usually rectangular, so the diffraction effect is more obvious, and the camera can cause the star awn phenomenon when taking a picture, and in the invention, the orthographic projection of the white sub-pixel W on the plane of the substrate base plate 00 comprises a second curve edge 2, the diffusion directions of external light passing through each point on the second curve edge 2 are all different, thereby produced the diffraction stripe that the diffusion direction is all inequality, diffraction effect intensity can weaken greatly, and the visibility is low, and the camera can not appear the starburst phenomenon when shooing.

Meanwhile, in the prior art, the white sub-pixel and the color sub-pixel are independently arranged, and the white sub-pixel and the color sub-pixel are independent from each other and do not overlap in the direction perpendicular to the plane of the substrate, so that a black matrix is arranged between the white sub-pixel and the color sub-pixel to prevent color mixing, and the black matrix occupies a certain space. Referring to fig. 2 and 3, the first curve edge 1 and the second curve edge 2 are at least partially overlapped, that is, the white subpixel W completely surrounds the color subpixel Y or partially surrounds the color subpixel, so that the space of the black matrix BM between the white subpixel W and the color subpixel Y can be reduced, the area of the white subpixel W can be increased on the premise that the area of the first display area AA1 is fixed, the light transmittance is improved, and the photographing effect is improved.

In the direction perpendicular to the plane of the substrate 00, the first sub-curve edge 11 and the second curve edge 2 both have an intersection point with the third edge 3, and at this time, the color sub-pixel Y intersects with the white sub-pixel W, so that the non-open area NK of the color sub-pixel Y can intersect with the non-open area NK of the white sub-pixel W, and thus when a signal line or a driving circuit is disposed in the non-open area NK of the color sub-pixel Y, the aperture ratio of the white sub-pixel W is not affected, and the white sub-pixel W is not blocked by the signal line or the driving circuit.
