Patent ID: 7843419

Claim:
A drive method for driving a pixel unit, wherein a first scanning line and a second scanning line define the pixel unit that includes a first sub-pixel and a second sub-pixel, the first sub-pixel includes a first transistor, a first pixel electrode and a first storage capacitor, the second sub-pixel includes a second transistor, a second pixel electrode and a second storage capacitor, wherein the first transistor and the second transistor couples with the second scanning line, the first pixel electrode couples with the first scanning line through the first capacitor, the second pixel electrode couples with a fix voltage source through the second capacitor and the first sub-pixel located in a reflective region of the pixel unit and the second sub-pixel located in a transmissive region of the pixel unit, comprising: providing a high level electric potential to the second scanning line to turn on the first transistor and the second transistor to write a data signal transferred from a data line to the first storage capacitor to form a first pixel electrode voltage and to write the data signal to the second storage capacitor to form a second pixel electrode voltage; and providing a low level electric potential to the second scanning line to turn off the first transistor and the second transistor and change the electrical potential of the first scanning line to change the first pixel electrode voltage through the first storage capacitor, wherein an electrical potential of the first pixel electrode is different from an electrical potential of the second pixel electrode.
