DEFINITION
Classification: 349/24
Optical excitation:
(under subclass 19) Subject matter wherein the liquid crystal material exhibits an optical property change across the liquid crystal in response to the nonthermal application of light to corresponding areas of the liquid crystal.
(1) Note. Included here are light activated switches.
(2) Note. Excluded from this subclass is light used to excite the liquid crystal by heating. For such excluded subject matter, see SEARCH THIS CLASS, SUBCLASS below.
SEE OR SEARCH THIS CLASS, SUBCLASS:
22, for changing the optical property of liquid crystal material in response to thermal application of incident light.
