Patent ID: 7429969

Claim:
A method for driving a current-driven Active Matrix Organic Light Emitting Diode (AMOLED) pixel, comprising: updating a current value of a current source of the AMOLED pixel; turning on a charging path used by the current source to charge a storage capacitor of the AMOLED pixel; in an initial stage of the turning on of the charging path used by the current source to charge the storage capacitor of the AMOLED pixel, in response to a scanning control providing a pre-charging signal, higher than zero voltage, to the current source to have the storage capacitor discharged in advance; wherein the pre-charging signal makes the storage capacitor to discharge to a pre-determined potential value; and completing the charging of the storage capacitor, and cutting off the charging path used by the current source to charge the storage capacitor of the AMOLED pixel.
