摘要： The invention belongs to the technical field of display, and specifically relates to a pixel structure and a display method thereof, and a display device including the pixel structure. The pixel structure comprises first pixel units and second pixel units which are sequentially arranged in staggered positions, wherein the first pixel unit (1) comprises a first sub-pixel (11) and a second sub-pixel (12) arranged in an oblique line, and the second pixel unit (2) comprises a third sub-pixel (21) and a fourth sub-pixel (22) arranged in an oblique line, and wherein the first sub-pixel (11) and the third sub-pixel (21) have different basic colors, and the second sub-pixel (12) and the fourth sub-pixel (22) have the same basic color. The pixel structure is capable of increasing the aperture ratios of sub-pixels while achieving high resolution, which not only simplifies the manufacture process, obtains good brightness level and extends the lifetime of product, but also prevents the error of color edge and the color nonuniformity by setting the weighted value of the missing basic color of the pixel structure in the display process, hence achieving better display effect.

摘要： A display substrate and a display device. The display substrate comprises a first color sub-pixel, a second color sub-pixel, and a third color sub-pixel. Each sub-pixel comprises a light-emitting region. Respective sides of each light-emitting region or extension lines thereof are sequentially connected to form a polygon. Multiple vertexes of the polygons of at least a portion of the sub-pixels have regions not overlapping with multiple corners of the corresponding light-emitting regions. Multiple corners of the light-emitting region of at least one sub-pixel at least include a first corner. An area of a region of the first corner not overlapping with a corresponding vertex of the polygon is larger than areas of regions of at least a portion of the remaining corners not overlapping with corresponding vertexes of the polygon. In an embodiment of the present disclosure, arrangement of a first corner on at least one sub-pixel facilitates adjusting centers of brightness in at least a portion of a display region, thereby realizing uniform distribution of the centers of brightness.
