Patent ID: 6949884

Claim:
A method for driving an organic light emitting diode (OLED), the method comprising: (a) providing a first metal oxide semiconductor (MOS) transistor, whose first and second ends are connected to the OLED and to a first voltage source respectively; (b) providing a capacitor, whose first end is connected to a gate of the first MOS transistor; (c) providing a second MOS transistor, whose first end is utilized for inputting data, a second end of the second MOS transistor being connected to the first end of the capacitor; (d) turning on the second MOS transistor and inputting data from the first end of the second MOS transistor to the second end of the second MOS transistor; and (e) turning off the second MOS transistor after step (d), and adjusting a voltage at a second end of the capacitor from a first voltage level to a second voltage level different from the first voltage level sequentially.
