摘要： The object of the invention is to provide a drive method suitable for driving a fast-responding STN liquid crystal display device which ensures a minimized cross talk and improved contrast in display. The drive method comprises a memory means for storing display data corresponding to a plurality of lines, a function generating means for generating a drive function for the row electrodes, an arithmetic means for computing the outputs from the foregoing means, a column electrode drive means for driving the column electrodes in dependency on the output from the arithmetic means, and a row electrode drive means for driving the row electrodes in accordance with respective row electrode drive functions. As a voltage function to be applied to each row during drive operation, a sum of a plurality of orthogonal functions is utilized. Thereby, degradation in contrast due to display patterns as well as the cross talk can be minimized. Further, arithmetic operation can be simplified in gradation display since application of a compensating voltage waveform is no more required.

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.
