Abstract
A method of driving an organic light emitting display, includes extracting information on deterioration of an organic light emitting diode (OLED) and information on a threshold voltage and mobility of a driving transistor included in each of the pixels to store the information in a memory unit during a non-display period, converting input data into corrected data using the information items stored in the memory unit, and supplying data signals corresponding to the corrected data to data lines, wherein, extracting the information, includes storing the information on the deterioration of the OLED and the information on the threshold voltage and mobility of the driving transistor in a non-volatile memory, and storing the information in a volatile memory.
