Title:
DRIVE CIRCUIT, DRIVE METHOD, AND DISPLAY APPARATUS
Document Type and Number:
WIPO Patent Application WO/2021/103183
Kind Code:
A1
Abstract:
A drive circuit, a drive method, and a display apparatus. The drive circuit may be used in a display panel (21). The drive circuit is provided with a control module (13). When an electrical current value on a common voltage drive module (14) is greater than a preset value, the control module (13) may control a power management integrated circuit (12) to stop outputting common voltage. Thus, when electrical current on a common voltage line is relatively large, voltage output to the common voltage drive module (14) is stopped, thereby preventing a large electrical current from burning or damaging a display screen.
