Display panel and display device

A display panel, comprising:

• a pixel circuit, including a driving transistor;
• and
• a driving circuit, configured to provide a signal for the pixel circuit, receive a third voltage signal and a fourth voltage signal, and generate an output signal, the third voltage signal being a high-level signal, and the fourth voltage signal being a low-level signal;
• wherein:
• a working process of the pixel circuit includes a reset phase and a separate bias phase;
• the output signal of the driving circuit is a reset signal in the reset phase;
• the output signal of the driving circuit is a bias signal in the bias phase;
• and
• in response to the driving transistor being a P-type transistor, the reset signal is the fourth voltage signal, and the bias signal is the third voltage signal;
• or
• in response to the driving transistor being an N-type transistor, the reset signal is the third voltage signal, and the bias signal is the fourth voltage signal.
