1. A display panel, comprising:
a display region and at least one non-display region adjacent to the display region, wherein a boundary between the at least one non-display region and the display region has a curve part; and
the display panel comprises: a plurality of pixels, distributed in a first direction and a second direction in an array; wherein:
the first direction intersects with the second direction,
the plurality of pixels comprise: a plurality of first pixel groups adjacent to the curve part, each first pixel group is divided into a plurality of first sub-pixel groups distributed in the first direction, each first sub-pixel group comprises at least one first sub-pixel, a width of the first sub-pixel in the first direction is smaller than a width of the first sub-pixel in the second direction;
a shape of the first pixel group and a shape of the first sub-pixel group are each a non-rectangle with the number of sides being greater than 3; and
the first pixel group comprises a first bottom side and a second bottom side parallel to the first direction and opposite to each other, a length of the first bottom side is smaller than a length of the second bottom side, and areas of the plurality of first sub-pixel groups comprised in the first pixel group are approximately equal;
wherein a plurality of first sub-pixels distributed in the first direction constitute a first pixel, and at least part of first pixel groups comprise only one first pixel; or, a plurality of first sub-pixels distributed in the first direction constitute one first pixel, and at least part of first pixel groups comprise a plurality of first pixels distributed in the second direction;
wherein the curve part comprises a plurality of circular arc parts, and a radian of each circular arc part is smaller than or equal to 90°;
wherein the plurality of pixels further comprise a plurality of second pixels, and shapes of the second pixels are rectangles;
second pixels comprise a plurality of second sub-pixels distributed in the first direction;
the quantity of the second sub-pixels comprised in the second pixels is the same as the quantity of the first sub-pixels comprised in the first pixels;
the plurality of pixels are divided into a plurality of pixel rows extending in the first direction and distributed in the second direction;
each circular arc part corresponds to n pixel rows, and each pixel row at least comprises a plurality of second pixels, wherein n is an integer greater than 1; an ith pixel row in the n pixel rows has a first semifocal chord Li1 and a second semifocal chord Li2 on a circumference corresponding to the circular arc part, wherein Li2>Li1, and 1≤i≤n; and
the first pixel groups are arranged in a region meeting (Li2-Li1)< (m−1) a/m, wherein a is a width of the second pixel in the first direction, and m is the quantity of second sub-pixels comprised in the second pixels.
