Graphic element Inexpensive low-consumption LCD technology
     
 
A low-energy, inexpensive surface-bistable nematic display uses passive matrix-like technology to produce high-speed, active matrix-like performance to rival the dominant Japanese.
 

The current liquid crystal display (LCD) market is 95 % controlled by Japanese manufacturers, with a variety of products, including dominant active matrix TFT devices which are very fast and highly multiplexable. Other competitors include Korea and the US, but as this project demonstrates, Europe still holds an edge in certain areas.

Partners have developed a new type of passive and highly multiplexable LCD using the surface bistability of nematics on pre-treated glass surfaces. This black-and-white device uses simple monostable planar and tilted anchorings and is controlled by short electric impulses, requiring much less energy than standard LCD screens. The cell has the usual sandwich geometry: the nematic fills the space between two flat transparent plates with an electric field perpendicular to the boundary plates.

The new Surface Bistable Nematic Display or SBIND compares favourably with high-speed active matrix TFT devices, but uses cheap passive matrix-like technology. We are talking about low-consumption, long-life, high-performance LCD screens that do not need batteries, say partners, a real alternative to the Japanese systems which now dominate the market.
