Abstract
An organic light emitting display device includes: a display panel; a timing controller configured to receive image data when a vertical sync signal is activated, to receive reference data corresponding to the image data when the vertical sync signal is deactivated, and to generate an emission control signal in accordance with emission duty information of the reference data; and an emission driver configured to supply first and second emission powers to the display panel, and to control a duration of a period during which a potential difference between the first and second emission powers is greater than or equal to a reference value in accordance with the emission control signal.
