Light-modulating cell |
摘要 |
A light-modulating cell and a display device based on a chiral nematic liquid crystal material in which the difference of optical rotation power between the planar nematic state and the focal conic state is used for discriminating between optical states, in particular for chiral nematic liquid crystal material having a pitch length associated with infrared light.
