An organic light emitting display and driving method of the same is provided to improve image quality by supplying a sub-pixel for compensating threshold voltage variation. In a sub pixel, a first transistor(TFT1) of which the gate is connected to a first scan wiring, and a first capacitor(C1) of which a first electrode is connected to a second electrode of the first transistor. A second transistor(TFT2) of which a gate is connected to the first scan wiring, and a third transistor(TFT3) of which a first electrode is connected to a second electrode of a second transistor. A second capacitor(C2) of which the second electrode is commonly connected to the second electrode and the second power line of the third transistor, and a fourth transistor(TFT4) of which a first electrode is commonly connected to the second electrode of the second transistor and the second electrode of the third transistor. An organic light-emitting DIODE(D) of which a second electrode is connected to a second electrode of a fourth transistor. |
