Grayscale Generation and Stabilization in Ferroelectric Liquid Crystal Display

Intrinsic grayscale generation and stabilization in ferroelectric liquid crystal display (FLCD) have been proposed and investigated. Study of the FLC samples shows that the switching process takes place through the formation and evolutions of domains formation. Dynamic current and electrooptical response in FLC testing cell are discussed as a criterion of memorized grayscale generation for FLC display. Grayscale stability for different crosstalk effects under a passive multiplex driving scheme is demonstrated. Passive 160 160 multiplex addressing photo-aligned 5- reflective FLCD with a high contrast and four memorized grayscale levels is developed.
