Patent ID: 8462089

Claim:
An organic light emitting display device, comprising: a display unit comprising a plurality of pixels coupled to a plurality of scan lines and a plurality of data lines; one or more control lines coupled to the pixels; a control line driver for supplying a plurality of control signals to the pixels through the one or more control lines; a first power driver for applying a first power having a low voltage level and a high voltage level to the pixels; and a second power driver for applying a second power having a low voltage level and a high voltage level to the pixels, wherein each of the pixels comprises: an organic light emitting diode; a driving transistor for controlling an amount of current supplied to the organic light emitting diode; an initializing transistor coupled to a gate electrode of the driving transistor and configured to be turned on during a reset period of one frame period to supply a reset voltage to the gate electrode of the driving transistor, the reset voltage having a voltage lower than the high voltage level of the first power; and a third transistor coupled between an anode electrode of the organic light emitting diode and the gate electrode of the driving transistor and configured to be turned on when control signals are supplied to the control lines.
