Fig. 1 is a schematic plan view of a display panel according to the present invention, fig. 2 is an enlarged schematic plan view of a portion a of the display panel shown in fig. 1, and referring to fig. 1 and 2, the present embodiment provides a display panel, which includes a first display area AA1 and a second display area AA2, and the second display area AA2 at least partially surrounds the first display area AA1. The light transmittance of the first display area AA1 is higher, so that the area corresponding to the first display area AA1 may be used for placing a photosensitive element, and the photosensitive element may be, but is not limited to, a camera, a light sensor, a distance sensor, a depth sensor, an iris recognition sensor, an infrared sensor, and the like.
It should be noted that, the first display area AA1 may be a rectangular area, a circular area, an oval area, or the like, and the position of the first display area AA1 may be set on any side of the display panel, and those skilled in the art may set the shape and the position of the first display area AA1 according to actual needs, which is not particularly limited in the embodiment of the present invention.
It should be noted that, in fig. 1, the second display area AA2 is exemplarily shown to completely surround the first display area AA1, and in other embodiments of the present invention, the second display area AA2 may also partially surround the first display area AA1.
The first display area AA1 includes a plurality of first pixel units 10, the first pixel units 10 including a first sub-pixel row 11 and a second sub-pixel row 12, the first sub-pixel row 11 including a plurality of first sub-pixels P1 arranged along a first direction X, the second sub-pixel row 12 including a plurality of second sub-pixels P2 arranged along the first direction X, the first sub-pixel row 11 and the second sub-pixel row 12 being arranged along a second direction Y, wherein the first direction X and the second direction Y intersect. Optionally, the first direction X and the second direction Y are perpendicular.
The first sub-pixel P1 is a high-transmittance sub-pixel, that is, the light transmittance of the first sub-pixel P1 is higher, so that the light transmittance of the first display area AA1 can be effectively improved by arranging the first sub-pixel P1 in the first display area AA 1. Alternatively, the first subpixel P1 may be a white subpixel.
The plurality of second sub-pixels P2 arranged in the first direction X in the second sub-pixel row 12 may include red, green, and blue sub-pixels.
That is, the first sub-pixel P1 and the second sub-pixel P2 are disposed in the first display area AA1, so that the first display area AA1 has a display function. Meanwhile, the first sub-pixel P1 is a high-transmittance sub-pixel, so that the light transmittance of the first display area AA1 can be improved, and the usability of the photosensitive element can be improved when the photosensitive element is placed in the area corresponding to the first display area AA 1.
The first display area AA1 includes a plurality of pixel cell columns 20, and the pixel cell columns 20 include a plurality of first pixel cells 10 arranged along the second direction Y. The two adjacent pixel unit columns 20 are a first pixel unit column 21 and a second pixel unit column 22, respectively, the first sub-pixel rows 11 in the first pixel unit column 21 and the first sub-pixel rows 11 in the second pixel unit column 12 are staggered in the first direction X, and the second sub-pixel rows 12 are surrounded by the first sub-pixels P1.
Specifically, in the first display area AA1, the first pixel units 10 in the pixel unit column 20 are arranged along the second direction Y, so that the first sub-pixel row 11 and the second sub-pixel row 12 in the pixel unit column 20 are arranged at intervals along the second direction Y. In the two adjacent pixel unit columns 20, the first sub-pixel rows 11 in the first pixel unit column 21 and the first sub-pixel rows 11 in the second pixel unit column 12 are staggered in the first direction X, so that the first sub-pixel rows 11 and the second sub-pixel rows 12 are arranged at intervals along the first direction X. Meanwhile, the second sub-pixel row 12 is surrounded by the first sub-pixel P1, so that a continuous strip structure formed by a part of the second sub-pixel row 12 in the first direction X in the first display area AA1 can be avoided, and a continuous strip structure formed by a part of the second sub-pixel row 12 in the second direction Y in the first display area AA1 can be avoided, so that the phenomenon of visible cross stripes caused by the brightness difference of the first sub-pixel P1 and the second sub-pixel P2 during display in the first display area AA1 can be relieved, and the display effect of the first display area AA1 can be effectively improved.
Alternatively, the light transmittance of the first display area AA1 may be increased by increasing the opening area of the first subpixel 11. In the embodiment of the present invention, a person skilled in the art may adjust the opening area of the first sub-pixel 11 according to actual production needs, so as to adjust the light transmittance of the first display area AA1, and the ratio of the opening area of the second sub-pixel 12 to the opening area of the first sub-pixel 11 may be set to be 1:0.5-1:5.
Alternatively, the embodiment of the present invention may adjust the opening area of the first sub-pixel 11 by adjusting the length of the first sub-pixel 11 along the first direction X, and/or by adjusting the length of the first sub-pixel 11 along the second direction Y. Illustratively, fig. 2 illustrates that the length of the first sub-pixel 11 along the second direction Y is greater than the length of the first sub-pixel 11 along the first direction X.
With continued reference to fig. 2, when the length of the first sub-pixel 11 along the second direction Y is greater than the length of the second sub-pixel 12 along the second direction Y, the first sub-pixels P1 surrounding the second sub-pixel rows 12 may be connected to each other, so that all the second sub-pixel rows 12 in the first display area AA1 are not connected to each other, thereby further alleviating the phenomenon that when the first display area AA1 displays, the cross lines are visible due to the brightness difference between the first sub-pixel P1 and the second sub-pixel P2, and effectively improving the display effect of the first display area AA 1.
It should be noted that, in fig. 2, the number of the first sub-pixels P1 arranged along the first direction X in the first sub-pixel row 11 in the first pixel row 21 is the same as the number of the first sub-pixels P1 arranged along the first direction X in the first sub-pixel row 11 in the second pixel row 22, in other embodiments of the present invention, the number of the first sub-pixels P1 arranged along the first direction X in the first sub-pixel row 11 in the first pixel row 21 is the same as the number of the first sub-pixels P1 arranged along the first direction X in the first sub-pixel row 11 in the second pixel row 22, and of course, the number of the first sub-pixels P1 arranged along the first direction X in the first sub-pixel row 11 in the first direction X in the second pixel row 22 is different from the number of the first sub-pixels P1 arranged along the first direction X in the first sub-pixel row 11 in the first direction X in the second pixel row 22, which, and referring to fig. 3 is another enlarged schematic diagram of the portion a of the display panel described in fig. 1, in other embodiments, the number of the first sub-pixel P1 in the first sub-pixel row 11 in the first pixel row 11 is not arranged along the first direction X in the first sub-pixel row 11 is the first sub-pixel row 11.
