Abstract
A circuit and method for eliminating image sticking during power-on and power-off, the circuit for eliminating image sticking during power-on and power-off includes a voltage detecting module and a common signal writing module; the voltage detecting module detects whether an operating voltage is lower than a first threshold voltage during power-on, and detects whether the operating voltage is lower than a second threshold voltage during power-off; and the common signal writing module writes, when the operating voltage is lower than the first threshold voltage during power-on or the operating voltage is lower than the second threshold voltage during power-off, a signal with a voltage equal to a voltage at a common voltage signal terminal at the same timing, to a data line.
