About This Article
Descriptions
A new liquid crystal two-color display device is presented. The device is based on a wave-length dependence of optical rotation angle in the nematic (MBBA) and cholesteric (CN) mixture. The change of the color utilizes discrete increment or decrement of the cholesteric helical pitch under the field Obtained two-color display has such practically favorable features as remarkably shorter rise-and recover-time (&le
