Abstract
Described herein are liquid crystal (LC) assemblies that are dimmable and techniques for manufacturing LC assemblies. Example LC assemblies are described that include a flexible substrate, a twisted nematic liquid crystal, a polarizer with cellulose triacetate and an ultraviolet blocker, a polycarbonate layer, polyvinyl butyral as a connecting layer, or any combination of these features. A flexible substrate can permit an LC assembly to be applied to a window or other rigid surface, even if the surface has a three-dimensional curvature. LC assemblies featuring Guest-Host or vertical alignment configurations are also described. In some embodiments, a dimmable LC assembly is provided as part of a kit including a control unit adapted to electrically connect to the LC assembly via a cable. Both the LC assembly and the control unit can be mounted to a window or other rigid surface. The control unit can be powered using a photovoltaic cell.
