Abstract
There is provided a method of driving an organic light emitting display capable of displaying an image with uniform brightness. The method includes storing a brightness characteristic corresponding to emission time of an organic light emitting diode (OLED), adding first data supplied in units of frames by pixels to generate accumulated data, extracting accumulated data of a pixel to which currently supplied first data is to be supplied and calculating maximum brightness corresponding to emission time of the extracted accumulated data, calculating maximum brightness corresponding to emission time of largest accumulated data among the accumulated data, controlling a bit value of the first data using maximum brightness of a pixel to which the first data is to be supplied and maximum brightness of the largest accumulated data to generate second data, and controlling a voltage value of a first power source supplied to the pixels in response to the maximum brightness of the largest accumulated data.
