Patent ID: 7800556

Claim:
A method for driving a pixel, the pixel having an organic light emitting diode (OLED), a storage capacitor, and a thin film transistor (TFT), the TFT having a first terminal, a second terminal, and a gate, the first terminal electrically being coupled to one end of the OLED, the other end of the OLED being adapted for receiving a first voltage, the second terminal being adapted for receiving a second voltage, the gate of the TFT being electrically coupled to an end of the storage capacitor, the method comprising: providing the second voltage to the end of the storage capacitor; providing a pixel voltage to the other end of the storage capacitor; discharging the storage capacitor via the TFT and the OLED until conductive current of the OLED is substantially zero and the storage capacitor stores an amount of charges; and generating a pixel current by the TFT for driving the OLED to emit light according to the amount of charges stored in the storage capacitor.
