Display panel and display device

A display device comprising a display panel, wherein the display panel comprises:

• a pixel circuit and a light-emitting element,
• wherein the pixel circuit comprises a data write module, a drive module, a compensation module and a reset module;
• wherein the drive module comprises a drive transistor;
• wherein the data write module is connected to the drive transistor;
• wherein the compensation module is connected to the drive transistor;
• wherein the rest module is connected between a reset signal terminal and the drain of the drive transistor;
• wherein the reset module is reused as a bias module;
• wherein an operation of the pixel circuit comprises a reset stage and a bias stage, during the reset stage, the reset module and the compensation module are on, and the reset signal terminal provides a reset signal for the gate of the drive transistor, during the bias stage, the reset module is on, the compensation module is off, and the reset signal terminal provides a bias signal for the drain of the drive transistor;
• wherein an operation of the display panel comprises at least two data write frames;
• wherein in the at least two data write frames, bias stages have different durations;
• a voltage of the bias signal is higher than a voltage of the reset signal.
