Abstract
Provided is a display panel includes a pixel circuit and a light-emitting element. The pixel circuit includes a drive circuit, a data write circuit and a bias compensation circuit. The operation process of the pixel circuit includes a data write stage, a first bias compensation stage and a second bias compensation stage. In the data write stage, the data write circuit is turned on, and a data voltage terminal writes a data voltage signal to a first terminal of the drive circuit. In the first bias compensation stage, the data write circuit is turned on, and the data voltage terminal writes the data voltage signal to the first terminal of the drive circuit. In the second bias compensation stage, the bias compensation circuit is turned on, and a bias compensation voltage terminal writes a bias adjustment voltage signal to the first terminal of the drive circuit.
