1. A display device, comprising a display area; wherein the display area comprises:
a first display sub-area; and
a second display sub-area, provided with a camera, wherein:
the first display sub-area comprises a plurality of groups of pixels, each group of pixels comprises a first pixel element and a second pixel element, each group of pixels comprises a first sub-pixel, two second sub-pixels and a third sub-pixel; the two second sub-pixels are located between the first sub-pixel and the third sub-pixel in a row direction; the plurality of groups of pixels are arranged in the row direction to form a plurality of rows of pixels, and the plurality of rows of pixels are arranged along a column direction;
the second display sub-area comprises a plurality of third pixel elements, each third pixel element comprises a first sub-pixel, a second sub-pixel and a third sub-pixel arranged adjacent to each other, the plurality of third pixel elements are arranged in the row direction to form a plurality of rows of pixel, the plurality of rows of pixels are arranged along the column direction, and lines connecting centers of the first sub-pixel, the second sub-pixel and the third sub-pixel in each third pixel elements form a triangle; and,
a distribution density of pixels in the first display sub-area is greater than a distribution density of pixels in the second display sub-area;
wherein a sub-pixel is located in one row of sub-pixels at an edge of the first display sub-area close to the second display sub-area, an another sub-pixel is located in one row of sub-pixels at an edge of the second display sub-area close to the first display sub-area, the sub-pixel is adjacent to the another sub-pixel, and a distance between the sub-pixel and the another sub-pixel is less than a length of the third sub-pixel of the third pixel element in the column direction; and/or
a sub-pixel is located in one column of sub-pixels at an edge of the first display sub-area close to the second display sub-area, an another sub-pixel is located in one column of sub-pixels at an edge of the second display sub-area close to the first display sub-area, the sub-pixel is adjacent to the another sub-pixel, and a distance between the sub-pixel and the another sub-pixel is less than a length of the third sub-pixel of the third pixel element in the row direction.
