  • Method and device for avoiding image sticking
    Patent number: 8284184
    Abstract: The present invention directs to a method an device for avoiding image sticking, the method for avoiding image sticking is to adjust a real common electrode voltage by difference between the real common electrode voltage and an ideal common electrode voltage, said difference is obtained by acquiring a real pixel electrode voltage on a panel; the device comprises a difference generation block for generating the difference between the real common electrode and the ideal common electrode voltage and an adjusting block for adjusting the real common electrode voltage, said adjusting block comprises an enabling block for generating a common electrode voltage adjustor enabling signal, a control block for generating a common electrode voltage adjustor control signal, and a common electrode voltage adjustor for adjusting the real common electrode voltage.
