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.

A display system includes: a transmissive liquid crystal display panel; a light control panel having an active area with a light control area; a temperature detector provided in the liquid crystal display panel and having a detection area with a resistive element; a backlight; and a controller. A display area of the liquid crystal display panel, the active area, and the detection area overlap on an optical path of a projection light. The light control panel is disposed at such an angle that, when the light control area is in a light reflection state, the light control panel reflects external light to a position out of the optical path and different from a position of the liquid crystal display panel. The controller causes the light control area to reflect light when an output indicating that the resistive element has a predetermined temperature or higher is obtained.
