LIQUID CRYSTAL WINDOW BONDING AND SEALING
Described herein are liquid crystal (LC) assemblies that are dimmable and techniques for manufacturing LC assemblies. In one example, an LC assembly comprises: a first curved glass panel, a second curved glass panel, and a liquid crystal panel having a first outer surface and a second outer surface, a layer of a liquid adhesive attaching the first curved glass panel and the first outer surface of the liquid crystal panel, and a film adhesive attaching the second curved glass panel and the second outer surface of the liquid crystal panel.
CONTROL SYSTEM FOR DIMMABLE FILM
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.

COMPACT IMAGING OPTICS USING LIQUID CRYSTAL (LC) FOR DYNAMIC GLARE REDUCTION AND SHARPNESS ENHANCEMENT
An optical assembly to reduce glare and enhance sharpness in a head-mounted device (HMD) is provided. The optical assembly may include an optical stack, such as pancake optics. The optical assembly may also include at least two optical elements. The optical assembly may further include at least one liquid crystal (LC) layer between the at least two optical elements, wherein the liquid crystal (LC) layer provides dynamic glare reduction and enhanced sharpness using a controllable polarization technique. In some examples, the controllable polarization technique may include determining optical assembly orientation using a sensor. Based the optical assembly orientation, the polarization of the at least one liquid crystal (LC) layer may be dynamically adjusted via adjustments in applied voltage to minimize or reduce glare and enhance visual sharpness.
