Title:
SHIFT REGISTER UNIT AND DRIVING METHOD THEREFOR, GATE DRIVING CIRCUIT, AND DISPLAY DEVICE
Document Type and Number:
WIPO Patent Application WO/2023/173259
Kind Code:
A1
Abstract:
Provided are a shift register unit and a driving method therefor, a gate driving circuit, and a display device, relating to the technical field of display. An output circuit in the shift register unit may control, on the basis of a potential of a second node and a potential of a fourth node, a first power supply end and a second power supply end to respectively transmit a first power supply signal and a second power supply signal to a first output end and a second output end at least within one same time period. Therefore, by flexibly setting a signal provided by each signal end, the potential of the second node and the potential of the fourth node can be controlled, so that the shift register unit can simultaneously transmit gate driving signals of different potentials to a pixel, thereby satisfying the requirement that one pixel needs to respond to a plurality of gate driving signals of different potentials to emit light. In this way, compared with the related art, the number of the required gate driving circuits is smaller, which is beneficial to the narrow frame design of the display device.
