Display substrate, display device and high-precision metal mask plate

Abstract

The invention provides a display substrate, a display device and a high-precision metal mask plate. The display substrate comprises first sub-pixels, second sub-pixels and third sub-pixels, the firstsub-pixels and the third sub-pixels are alternately arranged in the first direction to form first sub-pixel rows, and the second sub-pixels form second sub-pixel rows; the first sub-pixel rows and thesecond sub-pixel rows are alternately arranged in the second direction; two first sub-pixels and two third sub-pixels distributed in two adjacent rows and two adjacent columns form a 2 * 2 matrix, the two first sub-pixels and the two third sub-pixels in the matrix are located in different rows and columns, the center connecting lines of the two first sub-pixels and the two third sub-pixels form avirtual quadrangle, and the second sub-pixels are located in the virtual quadrangle; and at least two of the distances from the centers of the two first sub-pixels and the centers of the two third sub-pixels in the virtual quadrangle to the center of the second sub-pixels are different. According to the invention, the arrangement of the brightness centers of the virtual pixels is more uniform.

Description

technical field [0001] The present disclosure relates to the field of display technology, in particular to a display substrate, a display device, and a high-precision metal mask. Background technique [0002] An organic light-emitting diode display (Organic light-emitting diode, OLED) display device includes a base substrate, a light-emitting layer and a package protection layer, and the light-emitting layer includes sub-pixels arranged in a matrix on the base substrate. Each sub-pixel generally vapor-deposits the organic light-emitting material on the corresponding sub-pixel position of the array substrate through a fine metal mask (FMM). With the development of technology, people have higher and higher requirements on the resolution of display devices. [0003] Currently limited to the production level of FMM and the precision of the evaporation process, it is difficult to increase the high resolution by reducing the sub-pixel size and pixel pitch. A commonly used method...
