ABSTRACT:
In a method for driving a matrix liquid crystal display (LCD), whereby the selection ratio of a scanning electrode is improved and the voltage magnitude variation is considerably reduced, the scanning electrode driving signals are made to overlap each other according to an orthogonal function to then be sequentially applied to adjacent scanning electrodes. The data electrode driving signals are made to change in their voltage level through the step of maintaining an intermediate voltage level in the overlap interval to then be applied to data electrodes in the alternative, or the scanning electrode driving signals having opposite polarity are periodically applied to adjacent scanning electrodes. Therefore, the selection ratio of scanning electrodes are improved and the generation of the waveform differential is minimized, thereby reducing the crosstalk generated in a picture.
