Abstract: Disclosed are an organic light emitting display capable of preventing lowering of brightness and prolonging its a lifespan, and a driving method thereof. The organic light emitting display controls a level of a gate signal, by outputting a gate high voltage after controlling a level of the gate high voltage, according to a level of a threshold voltage sensed from each pixel of a display panel.
