Abstract: Disclosed are an organic light emitting display device and a driving method thereof, which prevent an OLED of each pixel from being burned in even when still images are continuously displayed on a display panel. When a certain time elapses after a display panel enters a PSR mode of displaying a still image, a timing controller may progressively decrease the control duty ratio for controlling the luminance of the display panel. Also, the timing controller prevents the OLED from being burned in when a still image is displayed.
