Abstract
A system such as a vehicle, building, or electronic device system may have a support structure with one or more windows. The support structure and window may separate an interior region within the system from a surrounding exterior region. Control circuitry may receive input such as user input and may adjust an adjustable layer in the window based on the input. The adjustable layer may be an adjustable light transmission layer. The adjustable light transmission layer may have a polymer matrix layer with embedded guest-host liquid crystal cells. Each cell may have liquid crystal material and dichroic dye. The adjustable light transmission layer may be operated in a dark state to prevent light from passing through the window, a clear state in which the window passes light, and intermediate states that exhibit intermediate light transmission levels.
