Abstract

PURPOSE: To always obtain optimum luminance and to improve the operability by making display luminance high in the case where the elapsed time is short after a user starts a display device and successively lowering the luminance with the lapse of time. CONSTITUTION: When the device is started, a timer 4 starts operation and measures the elapsed time. A luminance control part 3 controls so that the luminance may be kept high in the case the elapsed time is short and it may be made low to be settled as a fixed value as the elapsed time gets longer. Therefore, the display luminance is successively automatically adjusted with the elapsed time of the timer, the operability is improved, and the fatigue of the eyes is reduced.
