Pixel arrangement structure, display substrate, and display device

Abstract

A pixel arrangement structure, a display substrate, and a display device. The pixel arrangement structure comprises pixel groups () extending in a first direction and arranged in a second direction, and each pixel group () comprises a first sub-pixel row (), a second sub-pixel row (), and a third sub-pixel row (). The first sub-pixel row () comprises a plurality of first sub-pixels (), the second sub-pixel row () comprises a plurality of second sub-pixel pairs (), and the third sub-pixel row () comprises a plurality of third sub-pixels (). The pitches of the plurality of first sub-pixels (), the plurality of second sub-pixel pairs (), and the plurality of third sub-pixels () in the first direction are same. In each pixel group (), a line connecting the centers of a first sub-pixel () and a third sub-pixel () adjacent to each other are substantially parallel to the second direction, and the first sub-pixel row () and the second sub-pixel row () are shifted by one half of the pitch in the first direction. The orthographic projections of a second sub-pixel pair () and a first sub-pixel () adjacent to each other on a straight line extending in the first direction are overlapped, and the first sub-pixel rows () in the two adjacent pixel groups () are shifted by one-half of the pitch in the first direction. The pixel arrangement structure reduces the grainy sensation of the second sub-pixel pairs during display.
