Title:
POWER-ON AND POWER-OFF RESIDUAL IMAGE ELIMINATION CIRCUIT, AND METHOD FOR ELIMINATING POWER-ON AND POWER-OFF RESIDUAL IMAGE
Document Type and Number:
WIPO Patent Application WO/2017/117963
Kind Code:
A1
Abstract:
Provided are a power-on and power-off residual image elimination circuit, and a method for eliminating a power-on and power-off residual image. The power-on and power-off residual image elimination circuit comprises a voltage detection module (Xao) and a common signal write-in module, wherein the voltage detection module (Xao) is used for detecting, in a start-up process, whether a working voltage (VDD) is lower than a first threshold voltage, and detecting, in a shut-down process, whether the working voltage (VDD) is lower than a second threshold voltage; and the common signal write-in module is used for writing a signal with the equal voltage to a common signal terminal (Vcom) at the same moment into a data line (Data) when the working voltage (VDD) is lower than the first threshold voltage and lower than the second threshold value.
