Patent ID: 8284184

Claim:
A method for avoiding image sticking, characterized in comprising following steps: step 1 : generating a bias voltage between a real common electrode voltage applied to a common electrode and an ideal common electrode voltage according to a real pixel electrode voltage, wherein said real pixel electrode voltage is a positive voltage or a negative voltage on a pixel electrode with respect to a common electrode voltage, said ideal common electrode voltage is a voltage which makes the positive voltage and the negative voltage of said real pixel electrode voltage symmetrical wherein said step is effected by; step 11 : feeding back the real pixel electrode voltage acquired by a data line on a panel to a source driving integrated chip; step 12 : performing integrating process on each said real pixel electrode voltage; step 13 : performing averaging process on the resultant data of said integrating process; and step 14 : amplifying the resultant data of said averaging process by a corresponding multiple according to a refreshing rate, to obtain said bias voltage; and step 2 : adjusting the real common electrode voltage according to said bias voltage to make it consistent with the ideal common electrode voltage.
