Abstract
A liquid crystal matrix display provides scanning in a plurality of modes wherein the number of scanning electrodes simultaneously driven is varied. Higher driving duty cycles are used as the number of simultaneously driven scanning electrodes increases. Energy consumption is reduced and the quality is improved. A change-over circuit lowers the driving voltage during simultaneous scanning.
