Method of fabricating electro-optical devices with polymer-stabilized liquid crystal molecules
- 2006

Patent (other academic/artistic)abstract
- In a prepn. method, a chiral or cholesteric liq. crystal, a photoreactive monomer, and a photoinitiator are disposed in a liq. crystal cell. A principal surface of the liq. crystal cell is illuminated with UV light selected to have a nonuniform UV light intensity profile in the liq. crystal cell. The illuminating cooperates with the photoinitiator to polymerize at least a portion of the photoreactive monomer near the principal surface to generate a polymer network having a d. corresponding to the nonuniform UV light intensity profile. The polymer network biases the liq. crystal toward a selected helical alignment direction. In some embodiments, the illuminating includes illuminating with 1st and 2nd UV light intensity profiles to produce surface and vol. polymer network components.

Cholesteric liquid crystal display (LCD) device, and method for its production
- 2006
-
Patent (other academic/artistic)abstract
- A liq. crystal device is disclosed, having one or several display segments, and comprising: a first display substrate, a second display substrate, a layer of liq. crystal material disposed between said first and second substrate; and layer of conductive material disposed on said substrates. The conductive layers form electrodes for applying an elec. field across the liq. crystal for switching the liq. crystal material between a first optical state and a second optical state different from said first optical state. Image features of the display are further defined by the inclusion of a layer of patterned non-conductive or passive dielec. material on at least one of the substrates, said patterned material forming a mask defining image elements of the display segments.
