A method of driving an organic light emitting display device includes: receiving an image signal by sub-field with respect to a single frame comprising the N number of sub-fields (N is a natural number greater than 2) from the exterior; dividing a single sub-field into an address period and a display period and selectively calling a data signal of a single sub-field from the M number of sub-field memories (M is a natural number greater than 2); and applying the called data signal of the single sub-field to a sub-pixel.
