18 Claims

1. A pixel array, comprising a plurality of sub-pixels, each sub-pixel of the plurality of sub-pixels has a virtual pixel center, a width direction and a length direction of the sub-pixel are used as a width extending direction and a length extending direction of a defining quadrangle, respectively, and a width and a length of the sub-pixel are used as a width and a length of the defining quadrangle, respectively, and an intersection of diagonal lines of the defining quadrangle is used as the virtual pixel center; the plurality of sub-pixels comprise first sub-pixels, second sub-pixels, and third sub-pixels; the first sub-pixels and the third sub-pixels are alternately arranged along a first direction to form first pixel groups; the second sub-pixels are arranged side by side along the first direction to form second pixel groups; the first sub-pixels and the third sub-pixels are alternately arranged along a second direction to form third pixel groups; the second sub-pixels are arranged side by side along the second direction to form fourth pixel groups; the first pixel groups and the second pixel groups are alternately arranged along the second direction; the third pixel groups and the fourth pixel groups are arranged alternately along the first direction; wherein,

virtual centers of two first sub-pixels and two third sub-pixels in two adjacent first pixel groups and two adjacent third pixel groups are sequentially connected to form a second virtual quadrangle; a first virtual polygon comprises four second virtual quadrangles in an array and sharing adjacent sides; and the first sub-pixels and the third sub-pixels are at vertex angles or sides of the first virtual polygon and are alternately arranged on the vertex angles or the sides of the first virtual polygon along the clockwise direction;

the first virtual polygon has a first virtual point therein, lines connecting the first virtual point and virtual centers of the four third sub-pixels on the first virtual polygon divide the first virtual polygon into four virtual isosceles trapezoids;

wherein the virtual centers of four third sub-pixels in the first virtual polygon are sequentially connected to form a third virtual quadrangle;

the first virtual point is on a diagonal line of the third virtual quadrangle; and/or a virtual center of the first sub-pixel within the first virtual polygon is on a diagonal line of the third virtual quadrangle;

a virtual center of the first sub-pixel within the first virtual polygon is on a center of the third virtual quadrangle; and

the first virtual point within the first virtual polygon and the virtual center of the first sub-pixel are located at different positions on a same diagonal line of the third virtual quadrangle.
