Abstract

A pixel structure and a display panel. The pixel structure includes a plurality of first pixel sets arranged in an array along a first direction and a second direction, each first pixel set includes at least three sub-pixels of different colors, and at least three of the sub-pixels are a red sub-pixel, a green sub-pixel and a blue sub-pixel. Between two adjacent first pixel sets, the red sub-pixel in one first pixel set and the blue sub-pixel in another first pixel sets arranged adjacent to this one in the first direction are arranged non-adjacent to each other, and the red sub-pixel and the blue sub-pixel in each first pixel set are arranged adjacent to each other. The display panel includes the above pixel structure.
