Abstract
An organic light emitting display and a method for driving the same. An organic light emitting display includes: a frame memory having a first portion configured to store a first portion of image signals that is the same in an n−1th frame and an nth frame, and a second portion configured to store a second portion of the image signals that is different in the n−1th frame and the nth frame; a storing unit for storing the first portion of the image signals; a luminance controller for summing the second portion of the image signals and the first portion of the image signals stored in the storing unit to generate a frame data; and a scan driver for supplying light emitting control signals with a controlled pulse width according to a magnitude of the frame data.
