Abstract

A method is disclosed for driving a liquid crystal display provided, in the same liquid crystal panel, with a dot matrix display part and a fixed pattern or segment display part. The dot matrix display part is driven in a time-multiplexed fashion, while the fixed pattern or segment display part is driven in a static fashion using driving voltage waveforms in common with the dot matrix display part.
