Patent ID: 8896583

Claim:
A common electrode driving method, comprising: inputting the first common electrode signal to each row of pixels, and inputting the second common electrode signal to the common electrode, wherein the first common electrode signal and the gate signal applied to the corresponding row of pixels are transited synchronously and a polarity of a difference between a level of the first common electrode signal after the transition and a level of the first common electrode signal before transition is opposite to a polarity of a difference between a level of the gate signal applied to the corresponding row of pixels after the transition and a level of the gate signal applied to the corresponding row of pixels before transition, wherein the first common electrode signal and the second common electrode signal are generated by a driving signal generation circuit, and the driving signal generation circuit comprises: a first driving signal generation unit for generating the second common electrode signal; and a second driving signal generation unit for generating the first common electrode signal by generating a transition timing signal and superposing the transition timing signal on the second common electrode signal generated by the first driving signal generation unit.
