摘要： A liquid crystal display device providing a multi tone control function is disclosed, permitting a multi-colored display to be provided by using an analogue display data input, while regulating stepwise the brightness by varying the level of the applied voltage. The liquid crystal display device is composed of serial/parallel converter having a high sampling speed, into which liquid crystal display data are inputted, with a function of converting serial image data into parallel image data, and an X axis direction driver having a low sampling speed, into which the liquid crystal display data for one pixel are inputted, with a function of outputting the liquid crystal display data of one line in the horizontal direction, synchronized with a display line signal for a Y axis direction driver. The S/P converter and the X axis direction driver are disposed separately. Further the S/P converter and the X axis direction driver are constructed so as to hold analogue quantities in order to output the liquid crystal display data applied to the liquid crystal driving elements constituting the pixels of a liquid crystal display panel in the form of analogue signals. In this way a multi-colored display of not less than nine colors, using an analogue input, can be effected, and it is possible to display arbitrarily levels of brightness by varying the level of the applied voltage.
