    Abstract: A display panel includes a pixel circuit and a light-emitting element. The pixel circuit includes a driving module, a data-writing module, and a compensation module, and a reset module. The driving module includes a driving transistor. The data-writing module is connected to a source of the driving transistor and configured to selectively provide a data signal for the driving transistor. The compensation module is connected between a gate and a drain of the driving transistor. The reset module is connected between the drain of the driving transistor and a reset signal terminal and configured to provide a reset signal for the gate of the driving transistor. The reset module is used as a bias module. An operating process of the pixel circuit includes a reset stage and a bias stage.

    Abstract: A shift register and a display device are provided. A first control device, a second control device and an output device of the shift register all receive a first power signal and a second power signal as working power signals. The first control device controls a signal of a first node and a signal of a second node in response to a first drive signal. The second control device controls the signal of the first node in response to a second drive signal. The output device outputs a third drive signal in response to the signal of the first node or the signal of the second node, and the third drive signal is generated and outputted by utilizing the first drive signal and the second drive signal, and simplifying a circuit configuration of the shift register for generating the third drive signal.
