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： An image display device is arranged to convert analog video signals into digital video signals and display the corresponding image to the digital video signals. The image display device provides a variable delaying circuit for delaying an analog video signal of each color or a clock variable delay circuit for delaying a dot clock for generating each color dot clock and supplying each color dot clock as a conversion timing signal of an analog-to-digital converting circuit of the corresponding color. This kind of delay circuit is served to adjust a phase of the analog video signal or the dot clock of each color, thereby suppressing color blur even if the analog video signal contains skews among the colors.
