Cholesteric liquid crystal display system
摘要:
A method of writing an image on a liquid crystal display of the type having a layer of cholesteric liquid crystal material disposed between a pair of unpatterned conductors and a light absorbing layer for forming an image wise thermal pattern in response to an image wise pattern of light, including applying a first voltage to the conductors; applying a second voltage different from the first voltage to the conductors after applying the first voltage, wherein the first and second voltages are non-zero; and exposing the liquid crystal display to the image wise pattern of light.
