Abstract: The application provides a pixel compensation circuit, method and display panel. By use of a same data line, a first compensation sub-circuit and a second compensation sub-circuit drive a first pixel unit and a second pixel unit to emit light in a first period and a second period of display duration of each frame, respectively. In this way, both the first pixel unit and the second pixel unit are driven to emit light in each frame. Therefore, the number of the data lines can be reduced to a half, and it benefits in reducing pixel layout space and pixel size, thereby realizing high-resolution performance of the display panel.

Abstract: The present disclosure discloses a driving circuit and a display device. The driving circuit of the present disclosure inputs a level signal to a first node under the control of a first signal control terminal and a second signal control terminal, and then outputs a signal of a first power supply terminal or a second power supply terminal to the output terminal under the control of the level signal of the first node, so as to output different level signals under the control of two the control signals, thereby resolving a problem that one timing controller cannot be directly matched with different gate driving chips in use.

Abstract: A shift register, a gate driver circuit, and a display device are disclosed. In the shift register, when a pull-up node is at a low level, a third signal control end controls a conduction of a first noise reduction module and provides the pull-up node with a low-level signal of a first power supply end, so as to pull down a signal of the pull-up node to reduce noise. Therefore, an issue of noise interference on an output end of a gate driving signal is solved when a clock signal provided by a clock signal end is at a high level.
