Title:
GATE DRIVING CIRCUIT AND CONTROL METHOD THEREFOR, AND DISPLAY DEVICE
Document Type and Number:
WIPO Patent Application WO/2021/042873
Kind Code:
A1
Abstract:
A gate driving circuit. The gate driving circuit comprises: an input sub-circuit (110) configured to convert the potential of a first node (N1) from a first level to a second level under the control of a first input signal (SIN1); an output sub-circuit (120) configured to output a gate driving signal (SOUT) in response to a second input signal (SIN2); a first reset sub-circuit (130) configured to reset the potential of the first node (N1) under the control of a first reset signal (SRST1); at least one de-noising sub-circuit (140) configured to maintain the potentials of the first node (N1) and an output end of the output sub-circuit (120) at the first level in the case that the potential of the first ode (N1) is reset; and a function maintenance sub-circuit (150) configured to control the de-noising sub-circuit (140) to operate under the control of the first input signal (SIN1) so that the de-noising sub-circuit (140) interrupts the first node (N1) and a first voltage end. Also provided are a control method for a gate driving circuit and a display device. The output of the gate driving signal of the gate driving circuit is not affected by characteristic drift of a switching transistor.
