Abstract: An organic light emitting display includes a plurality of pixels. Each pixel includes an organic light emitting diode, a first driver, and a second driver. The first driver supplies a predetermined current to the OLED based on a current data signal or first data signal. The second driver is coupled between the first driver and OLED, and controls the coupling between the first driver and OLED based on a second data signal.
