Abstract: 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.

Abstract: A display system includes: a transmissive liquid crystal display panel; a scattering panel having a scattering area provided with a scattering portion; a temperature detector having a temperature detection area provided with a resistor element; a light source configured to emit projection light to the liquid crystal display panel; and a controller configured to control operations of the scattering panel and the light source based on an output of the temperature detector corresponding to a temperature of the resistor element. A display area of the liquid crystal display panel, the scattering area, and the temperature detection area overlap one another. The projection light that has passed through the display area and the scattering area is projected onto a light-transmitting projection target. When an output indicating that the temperature of the resistor element is a predetermined temperature or higher is acquired, the controller causes the scattering portion to scatter light.
