Abstract
A display panel includes a pixel circuit and a light-emitting element. The working process of the pixel circuit includes a data write stage and a bias stage. The working process of the pixel circuit includes a first light emission stage and a first non-light emission stage. In the first non-light emission stage, a bias maintaining stage is from the start moment of the bias stage to the start moment of the first light emission stage. Working modes of the display panel include a first mode and a second mode. The display brightness of the display panel in the first mode is different from the display brightness of the display panel in the second mode. The length of the bias maintaining stage in the first mode is different from the length of the bias maintaining stage in the second mode.
