摘要： 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.

摘要： A dot matrix display system for multiple-tone displays, including a display device in which pixels are arrayed in a matrix shape, an LC (liquid-crystal) drive signal generator which converts color display data into LC display data, an 8-level data driver which selects one of 8-level voltages in accordance with the LC display data and then delivers the selected voltage, and an 8-level applied LC voltage generator by which the 8-level applied LC voltages to be applied to the pixels are produced so as to substantially make uniform color differences between the respectively adjacent tones of the multiple-tone displays. Owing to the substantially uniform color differences between the respectively adjacent tones, the multiple-tone displays which are uniformly seen by the human eye can be realized.
