Optical modulation device and driving method therefor.

摘要

An optical modulation device is disclosed, which includes: a first substrate having thereon a signal transmission electrode connected to a signal source and a first electrode having a delay function connected to the transmission electrode; a second substrate having thereon a second electrode disposed opposite to said first electrode; and an optical modulation material, particularly a ferroelectric liquid crystal, disposed between the first and second electrodes. An optical modulation system, particularly a gradational display system, utilizing the delay function is also disclosed.
