Abstract
A display panel includes a pixel circuit and a light-emitting element. The pixel circuit includes a data write device, a drive device and a bias adjustment device. The data write device is configured to provide a data signal to the drive device. The bias adjustment device is configured to provide a bias adjustment signal to the drive device. The display panel further includes a drive circuit, the drive circuit is configured to receive a first drive signal and a second drive signal. In a case where the drive device includes a drive transistor being a PMOS transistor, the bias adjustment signal is same as the first drive signal, or, in a case where the drive device includes a drive transistor being an NMOS transistor, and the bias adjustment signal is same as the second drive signal.
