Patent ID: 8786532

Claim:
A method for driving a pixel structure, the pixel structure disposed on a first substrate and electrically coupled to at least one scan line and at least one data line, the pixel structure having a first switch device, a second switch device, at least one pixel electrode, at least one control electrode, and at least one coupling electrode, the first switch device and the second switch device electrically coupled to the same scan line and the same data line, the method comprising: turning on the first switch device and the second switch device simultaneously, providing a voltage corresponding to a displaying data to the pixel electrode via the second device and to the control electrode via the first switch device, wherein the pixel electrode directly receives the voltage from the second switch device and not receives the voltage from the first switch device, but the control electrode directly receives the voltage from the first switch device and not receives the voltage from the second switch device, such that the pixel electrode and the control electrode are at a floating connection state; providing a first coupling voltage to the coupling electrode; and coupling a variation of the first coupling voltage to the control electrode via at least one coupling capacitor, such that an absolute value of a voltage difference between the control electrode and a common electrode substantially is greater than an absolute value of a voltage difference between the pixel electrode and the common electrode, wherein the common electrode is disposed on a second substrate and the second substrate is corresponding to the first substrate.
