METHOD AND APPARATUS FOR OVERVOLTAGE PROTECTION
Document Type and Number:
WIPO Patent Application WO/2020/056908
Kind Code:
A1
Abstract:
Embodiments of the present application provide an overvoltage protection method, an overvoltage protection apparatus, and a display apparatus. When a voltage value of an output signal is greater than a first preset voltage threshold, whether the voltage value of the output signal satisfies a preset overvoltage protection condition is determined, and if it is detected that the voltage value of the output signal satisfies the preset overvoltage protection condition, a first control signal is outputted to control the output signal to stop output or to reduce the voltage value of the output signal.
