An organic light emitting diode (“OLED) display comprises a plurality of pixels which receives a first data signal, which is a data signal of a frame, through a plurality of data lines connected thereto, and stores the first data signal during a frame period of the frame, where the pixels simultaneously emit light based on a driving current corresponding to a second data signal, which is a data signal of a previous frame, where the frame period includes a scan period, during which the first data signal is stored, and a light emission period, during which the light is emitted based on the second data signal, the scan period and the light emission period overlap each other in the frame period.
