Abstract

A display device and a display panel thereof. The display panel has a display area and a frame area, where the display panel includes second pixel units disposed in the display area, and each of the second pixel units include: first sub-pixels, second sub-pixels and third sub-pixels alternately distributed in a column direction and emit three different primary colors respectively, and sub-pixels emitting a same color in each of the second pixel units are synchronously controlled to emit light. The display panel further includes color deviation adjustment sub-pixels disposed in the display area and between the second pixel units and the frame area, and the color deviation adjustment sub-pixels are independently controlled to emit light.
