Drive device for a display device, a drive method of a display device and a display device using the same.

The present invention relates to a drive apparatus, a drive method of a display device and a display device using the same of the display device. The display device includes a voltage of the photo-sensing unit for sensing a display panel, a light for displaying an image, an outside luminance detector to sense the light detecting node connected to the light sensor to provide an external luminance signal, the light in the first mode sense node adjusting the brightness of an image displayed by sensing the level and provides the external luminance signal by sensing a current level of the light detecting node in a second mode using the external luminance detection portion and the external luminance signal provided by the external luminance signal from the display panel and a luminance control section for. Display device. An optical measuring unit, the luminance
