Abstract: The present disclosure relates to a shift register unit and driving method thereof, a gate driving circuit and a display device. The shift register unit comprises: an input module for controlling a level of a first node based on a scan pulse, an output module for controlling a scan pulse output based on the level of the first node, a reset module for resetting the first node and the scan pulse output, and a control module for generating a reset trigger signal, wherein the reset module further resets the first node based on the reset trigger signal. The shift register units can be cascaded to form a gate driving circuit to realize output of multiple scan pulses. By integrating such a gate driving circuit on the array substrate, area of the bezel region of the array substrate can be reduced, thereby facilitating bezel narrowing of a display device. At the same time, due to presence of the control module, the reset module is enabled to reset the first node more stably while normal output of the scan pulse is maintained.

Abstract: A shift register, a driving method, a gate driving circuit and a display device are disclosed. The input module controls the potential of the first node. The first reset module controls the potential of the first node. The second reset module controls the potential of the driving signal output terminal. The first output module controls the potential of the driving signal output terminal under the control of the first node. The second output module controls the potential of the driving signal output terminal under the control of the second node. The pull-down driving module controls the potentials of the first node and the second node. Since the node control signal at the node control signal terminal can eliminate the noise on the first node resulting from the change in the first clock signal, the output stability of the shift register can be improved.

Abstract: A display panel provided according to the present disclosure may include an optical component and two Guest Host liquid crystal cells located at two opposite sides of the optical component. The optical component is used for reflecting light with a specific wavelength and transmitting other light. The Guest Host liquid crystal cells each include a plurality of pixel units each having two operation states of transmitting natural light and linearly polarized light. When the pixel units transmit the linearly polarized light, the light reflected by the optical component cannot pass through the pixel units, thereby achieving a dark state display.
