Abstract

See full text

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 have a polymer matrix layer with embedded cells. The cells may include intermixed guest-host liquid crystal cells and liquid crystal cells. The guest-host liquid crystal cells and liquid crystal cells may have different liquid crystal materials and/or different sizes that allow the guest-host liquid crystal cells and liquid crystal cells to electrically switch states at different respective threshold voltages. Based on the user input or other input the control circuitry can adjust a drive signal across the adjustable layer to change light transmittance and haze.
