Abstract:
An organic light emitting display is disclosed. The display includes a pixel unit for displaying a black image during a non-emission period and for displaying an image based on data during an emission period in every frame period. The display also includes a current sensor which determines current flowing in a power line during the non-emission period and generates a stop signal if the current is greater than a threshold, and a power supply which supplies power to the pixel unit unless the stop signal is received from the sensor.
