Title:
SHIFT REGISTER, GATE DRIVING CIRCUIT, AND DISPLAY PANEL
Document Type and Number:
WIPO Patent Application WO/2022/089070
Kind Code:
A1
Abstract:
The present invention relates to the technical field of display, and provides a shift register, a gate driving circuit, and a display panel. The shift register of the present invention comprises: an input circuit, configured to pre-charge and reset a pull-up node; a pull-down control circuit electrically connected to a pull-down circuit by means of a pull-down node, and configured to control the potential of the pull-down node under control of a first power supply voltage; each pull-down circuit, configured to pull down the potential of the pull-down node in response to the potential of the pull-up node; an output circuit, configured to output a clock signal by means of a signal output end in response to the potential of the pull-up node; a first noise reduction circuit connected to a pull-down node, and configured to perform noise reduction on outputs of the pull-up node and the signal output end by means of a non-working level signal in response to the pull-down node; and a first auxiliary circuit electrically connected to a pull-down node, and configured to pull down the potential of the pull-down node by means of the non-working level signal during a pre-charging stage in response to an input signal.
