A 1″ × 0.5″ FLC bar-graph display with short-term memory

Abstract

The development of an SSFLC cell to be used as an optical switching element is presented. The bar-graph type cell is composed of 96 stripe-electrodes of 200 micron width. Technical aspects of cell construction, such as electrode and thickness control, are discussed together with the electro-optic peiformance and contrast of cells with different surface coatings. Finally, the driving technique for the cell is presented.
