Liquid crystal display device having two metastable states and driving method therefor |
摘要 |
A high speed multiplex-driven liquid crystal display device is capable of utilizing a bistable nematic liquid crystal medium while maintaining high contrast, fast switching capability and a wide viewing angle. The chiral nematic liquid crystal medium has a twisted structure wherein a first voltage waveform applied in a first time period brings on Frederick's transition followed by a selected second voltage waveform applied in a second time period capable of generating one of two selectable metastable states representing switchable bistable states.
