Title:
GATE DRIVE UNIT CIRCUIT, GATE DRIVE CIRCUIT, DISPLAY APPARATUS AND DRIVE METHOD
Document Type and Number:
WIPO Patent Application WO/2020/063119
Kind Code:
A1
Abstract:
Disclosed are a gate drive unit circuit, a gate drive circuit and a method for driving the gate drive unit circuit. The gate drive unit circuit comprises an input sub-circuit (1) and an output sub-circuit (2). The input sub-circuit (1) is connected to a first pull-up node (PU1), a second pull-up node (PU2) and an input end (INPUT), and the input sub-circuit (1) transmits, under the control of a signal input by the input end (INPUT), the signal input by the input end (INPUT) to the first pull-up node (PU1) and the second pull-up node (PU2). The output sub-circuit (2) is connected to the first pull-up node (PU1), the second pull-up node (PU2), a first control end (CLKA), a third control end (CLKC), a first output end (OUTPUT1) and a second output end (OUTPUT2). The output sub-circuit (2) transmits, under the control of the potential of the first pull-up node (PU1), a signal input by means of the first control end (CLKA) to the first output end (OUTPUT1), and transmits, under the control of the potential of the second pull-up node (PU2), a signal input by means of the third control end (CLKC) to the second output end (OUTPUT2), wherein an active level of the signal of the first control end (CLKA) is greater than an active level of the signal of the third control end (CLKC).
