    Abstract: The disclosure provides a pixel array and a display device. The pixel array includes a plurality of sub-pixels, each of which has a virtual pixel center, the plurality of sub-pixels include first sub-pixels, second sub-pixels, and third sub-pixels; virtual centers of two first sub-pixels and two third sub-pixels are sequentially connected to form a second virtual quadrangle; a first virtual polygon includes 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 on the vertex angles or the sides of the first virtual polygon along a 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.

    Abstract: The disclosure provides a mask plate and a manufacturing method thereof. The mask plate includes at least one pattern region, each pattern region includes a first opening region and a second opening region which are adjacent to each other along a lengthwise direction of the mask plate, each of the first opening region and the second opening region has a plurality of pattern openings penetrating through the mask plate along a thickness direction of the mask plate, a ratio of a sum of areas of the pattern openings in the second opening region to a total area of the second opening region is greater than a ratio of a sum of areas of the pattern openings in the first opening region to a total area of the first opening region, the first opening region has grooves not penetrating through the mask plate.

    IPC: G09G3/20

    Abstract: A display substrate, a method for driving the same, a display device, and a high-precision metal mask are provided. The display area includes a first display sub-area in which pixels are distributed at a high density (e.g., a high resolution), and a second display sub-area in which pixels are distributed at a low density (e.g., a low resolution), and a transition display sub-area, with a distribution density of pixels (a resolution) between the distribution density of pixels in the first display sub-area and a distribution density of pixels in the second display sub-area, is arranged between the first display sub-area and the second display sub-area.

    Abstract: A pixel arrangement includes a plurality of first groups of sub-pixels arranged in a first direction, each first group including first sub-pixels and third sub-pixels arranged alternately. A plurality of second groups of sub-pixels are arranged in the first direction, each second group including third sub-pixels and second sub-pixels alternately arranged. The first groups and the second groups are alternately arranged in a second direction intersecting the first direction. The first groups and the second groups are arranged to form a plurality of third groups of sub-pixels arranged in the second direction and a plurality of fourth groups of sub-pixels arranged in the second direction. The third groups and the fourth groups are alternately arranged in the first direction, each third group including first sub-pixels and third sub-pixels alternately arranged, each fourth group including third sub-pixels and second sub-pixels alternately arranged.
