Patent ID: 8237634

Claim:
A pixel of an organic light emitting display device comprising: an organic light emitting diode coupled between a first power and a second power; a pixel circuit coupled between the first power and the organic light emitting diode for supplying a driving current to the organic light emitting diode; and a first transistor for supplying a reset voltage to an anode electrode of the organic light emitting diode during a first period when a previous scan signal is supplied to a previous scan line coupled to the first transistor, wherein the pixel circuit comprises: a second transistor coupled between a data line and a first node and having a gate electrode coupled to a current scan line; a third transistor coupled between the first node and the organic light emitting diode and having a gate electrode coupled to a second node; a first capacitor coupled between the second node and the first power; a fourth transistor coupled between the gate electrode of the third transistor and a drain electrode of the third transistor, and having a gate electrode coupled to the current scan line; a fifth transistor coupled between the first power and the first node, and having a gate electrode coupled to a light-emitting control line; a sixth transistor coupled between the third transistor and the organic light emitting diode, and having a gate electrode coupled to the light-emitting control line; and a seventh transistor coupled between the second node and an initialization power, and having a gate electrode coupled to the previous scan line.
