    摘要： An organic light emitting diode display for removing a voltage which is charged into a gate electrode of a driving transistor before a current frame is changed to a next frame is disclosed. In the organic light emitting diode display, a display panel has a plurality of pixels that include an organic light emitting diode. A timing controller controls a driving timing of the inputted video data and controls a supply timing of a refresh voltage. A data driver converts a digital data which is outputted from the timing controller for a current frame into an analog data voltage to supply it to the pixels, and then supplies the refresh voltage to pixels which are selected among the pixels in accordance with a control of the timing controller. And a gate driver primarily supplies a scanning pulse for a first horizontal period of a current frame to select the pixels to be supplied with a data, and then secondarily supplies a scanning pulse for a second horizontal period of a current frame to select pixels to be supplied with the refresh voltage among the pixels in accordance with a control of the timing controller.
