Title:
DRIVE CIRCUIT, DRIVE METHOD, AND DISPLAY APPARATUS
Document Type and Number:
WIPO Patent Application WO/2023/206219
Kind Code:
A1
Abstract:
Provided in the present disclosure are a drive circuit, a drive method, and a display apparatus. The drive circuit comprises a first pull-down node, a first control circuit, and a pull-up node reset circuit, wherein the first control circuit controls, under the control of a first control signal, the first pull-down node to communicate with a first voltage terminal, such that the electric potential of the first pull-down node is an effective voltage; and when the electric potential of the first pull-down node is an effective voltage, the pull-up node reset circuit controls a pull-up node to communicate with a second voltage terminal, so as to reset the electric potential of the pull-up node. By means of the present disclosure, the noise reduction capability of a transistor comprised in a pull-up node reset circuit can be improved, so as to prevent the drive circuit from performing erroneous output, such that the drive circuit can correctly output drive signals.
