Abstract

Embodiments of the present disclosure provides a display panel, a display device, and a display method. A density of a first pixel unit in a first display area is smaller than a density of a second pixel unit in a second display area. In the first pixel unit, a first sub-pixel row includes sub-pixels of different colors arranged along a first direction, and a second sub-pixel row includes first high-transmittance sub-pixels. A plurality of first pixel units are arranged along a second direction to form a first pixel unit column. In one of first pixel unit columns, the first sub-pixel rows and the second sub-pixel rows are alternately arranged. Two closest first sub-pixel rows are located in two adjacent first pixel unit columns and staggered from each other in the first direction.
