Abstract: An organic light-emitting diode display and a method of driving the same are disclosed. In one aspect, the display includes a light emission control line configured to provide a light emission control signal and a power line configured to provide a power voltage. An operation control TFT is electrically connected to the power line and configured to be turned on based on the light emission control signal so as to provide the power voltage. A driving TFT is electrically connected to the operation control TFT, an OLED is electrically connected to the driving TFT, and an initialization TFT is configured to provide the power voltage to the driving TFT. In a frame of the OLED display, the power voltage provided when the initialization TFT is turned on and the power voltage provided when the operation control TFT is turned on are different from each other.
