In one embodiment, referring to fig. 5, the plurality of third sub-pixels 31 includes a plurality of first setting sub-pixels 311 and a plurality of second setting sub-pixels 312, and the sum of the areas of the plurality of first setting sub-pixels 311 is equal to the second area; the sum of the areas of the plurality of second set sub-pixels 312 is equal to the difference between the first area and the second area;
from the first side of the second light-emitting display region 30 to the second side of the second light-emitting display region 30, the luminance of each first setting sub-pixel 311 in the plurality of sub-regions gradually changes from the first luminance La to the second luminance Lb; the brightness of each second setting sub-pixel 312 in the sub-regions gradually changes from a third brightness L0 to a second brightness Lb, the first side is close to one side of the multiplexing functional region 10, and the second side is close to the first light-emitting display region 20, that is, the brightness of the first setting sub-pixel from inside to outside gradually changes from the first brightness La to the second brightness Lb, and the brightness of the second setting sub-pixel from inside to outside gradually changes from the third brightness L0 to the second brightness Lb; therefore, the display difference caused by the abrupt change of the pixel density is further eliminated, and the display effect is further improved.
In one embodiment, to further improve the luminance uniformity between the sub-regions, the first luminance La is equal to the second luminance Lb multiplied by the first area.
In one embodiment, in order to further improve the brightness uniformity between the sub-regions, the areas of the sub-regions are equal. It is understood that the areas of the sub-regions may be different, and are specifically set according to the requirements, and are not limited herein.
