PURPOSE: An OLED display device driving a display panel through mode conversion is provided to supply low consumption power by converting a playing mode as a video mode, a standard mode and a black and white mode according to purpose. CONSTITUTION: A mode switching part switches a standard mode and a video mode based on the input of a video mode signal. The video data adjustment factor circuit(12) and a gamma counting circuit(13) vary the calculating coefficient of the video data. A light-off signal generator(15) performs the driving control conversion for light-off drive. The driver circuit outputs the video data adjustment factor, video signal and lighting signal, which is calculated by the gamma counting circuit, to a display panel(30).
