Patent ID: 7468716

Claim:
A method of driving a display device, the method comprising: determining a first difference Δ 1 , wherein Δ 1 is a difference between gray signals of two consecutive frames; comparing Δ 1 to a predetermined value to obtain a comparison result; using the comparison result to determine a modified current gray signal; and, applying the modified current gray signal to a current frame; wherein the gray signals are a current gray signal for the current frame and a previous gray signal for a frame preceding the current frame; wherein the predetermined value is a first predetermined value and the comparison result is a first comparison result, and further comprising: determining a second difference Δ 2 , wherein Δ 2 is a difference between the current gray signal and a next gray signal for a frame succeeding the current frame; comparing Δ 2 to a second predetermined value to obtain a second comparison result; and, using the second comparison result to determine the modified current gray signal.
