ABSTRACT:
A method of driving a liquid crystal device, which comprises matrix-addressed driving a liquid crystal device comprising a liquid crystal, particularly a ferroelectric liquid crystal, disposed between a pair of substrates and comprising finely distributed domains differing in threshold voltage for use in switching said liquid crystal, said method being a pulse modulation method comprising modulating at least one of pulse voltage and pulse width, a pixel electrode division method, or a time integration method. Also claimed is a liquid crystal device driven by any of said methods. The liquid crystal device provides a further improved analog multiple gray-scale level display, realizes a large-area display at a low cost, and enables drive at full color video rate.
