Abstract: An organic light emitting diode display device calculates a cumulative current of each of the plurality of pixels, calculates a consumed current consumed by each of the plurality of pixels during a reproduction period of the image, estimates an expected deterioration time of each of the pixels based on a difference between the cumulative current and the consumed current, and operates the display unit in a normal output mode as an image output mode when a number of pixels expected to burn in among the plurality of pixels based on the estimated expected deterioration time is less than a preset number.
