ABSTRACT:
A display device includes plural red, green, and blue pixels provided with current-driven type red-, green-, and blue-light-emitting elements, respectively. A method of driving the display device includes writing a video signal voltage into each of the pixels in a state in which all the light-emitting elements cease to emit light during a first portion of one frame period at a beginning thereof, and then operating a respective one of the light-emitting elements to emit light during at least one portion of the one frame period succeeding the first portion. Each of the at least one portion of the one frame period is determined by light emission characteristics of the respective one of the light-emitting elements, and also is determined by the video signal voltage of the respective one of the pixels.
