ABSTRACT:
A method of activating a matrix liquid crystal display formed with column electrodes intersecting row electrodes and liquid crystal material therebetween in which liquid crystal pixels are defined at the intersections of the row and column electrodes. The column electrodes are provided with voltage waveforms of high and low magnitude corresponding to display data. The row electrodes are supplied with a sequential scanning signal of activating magnitude. During one data output period, a signal for the data about the selected rows is delivered with one polarity and then switches to the opposite polarity N number of times (where N is a positive integer) during the same data output period to prevent crosstalk in the column electrodes.
