Bistable liquid crystal twist cell |
摘要 |
A bistable liquid crystal twist cell is disclosed. The cell is characterized by at least two stable states which exist indefinitely as long as not external energy is applied to the cell. External energy is necessary only for switching the cell between the stable states. Cell configurations which permit the fabrication of patterned displays are additionally disclosed. Specific embodiments include new techniques for switching the cell between the stable states.
