摘要： 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.

摘要： In one example, a liquid crystal (LC) assembly includes a first curved glass layer and a second curved glass layer. The LC assembly further includes a film-based, flexible LC stack structure between the first curved glass layer and the second curved glass layer. The film-based, flexible LC stack structure includes Guest-Host (GH) liquid crystals. The film-based, flexible LC stack structure is configured to provide both a display operation for displaying content to one or more user and a dimming operation for reducing a transmittance level of light passing through the LC assembly.

摘要： Described herein are liquid crystal (LC) assemblies that are dimmable and techniques for manufacturing LC assemblies. In some embodiments, an LC assembly includes a Guest-Host (GH) liquid crystal layer containing nematic liquid crystals, dye molecules, and a chiral dopant. The GH liquid crystal layer is located between a pair of substrates. The LC assembly is a film assembly, with each of the substrates including a flexible film and a conductive layer formed on the flexible film. The substrates are separated by spacers that define a cell gap. The GH liquid crystal layer is configured to transition the LC assembly between darkened and lightened states depending on the voltage across the conductive layers. The flexible films allow the LC assembly to conform to the surface of a window or other rigid surface to which the LC assembly is attached. The LC assembly can be attached via a liquid or film-based adhesive.
