ABSTRACT:
The number of vertical scanning in one field of a video signal is detected, and the number of scanning lines pulses at each row electrode of a liquid crystal display is determined in accordance with the difference between the determined number of vertical scanning lines number and the number of the row electrodes. The determined number of scanning pulses is stored in a retrace line interval. Scanning pulses are applied to the corresponding row electrode in a scanning interval. The number of row electrodes to which the scanning pulses are applied is the stored number of scanning pulses.
