ABSTRACT:
A pixel circuit and an organic light emitting display using the pixel circuit and a pixel circuit driving method capable of displaying an image of desired brightness are disclosed. The pixel provides a current for an organic light emitting diode which is not affected by a kickback voltage which occurs at the end of an initialization phase. The pixel also provides a current for an organic light emitting diode which is substantially not affected by a voltage drop in the power supply providing the current.
