Abstract: Disclosed is an organic light-emitting display device including: a display panel; a drive IC configured to supply a driving signal to the display panel; and a controller configured to operate in one of a first driving scheme, in which, when turned on, a sensing period of sensing characteristics of the display panel is executed, after which a display period of displaying an image on the display panel is executed, and a second driving scheme, in which, when turned on, the display period of displaying the image on the display panel is executed, the controller operating in the second driving scheme when turned on within a preset time after having been turned off.
