Organic light emitting display device and driving method thereof

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 the still image is displayed. 公开了种即使在显示面板上持续显示静止图像时仍可防止每个像素的OLED被烧毁的有机发光显示装置及其驱动方法。当在显示面板进入显示静止图像的PSR模式之后过去特定时间时，时序控制器可逐渐减小用于控制显示面板的亮度的控制占空比。此外，时序控制器防止当显示静止图像时OLED被烧毁。
