  • Patent number: 11376964
    Abstract: A vehicle display device includes a display device, a reflecting mirror, an optical sensor configured to detect external light, and a controller configured to enable execution of a temperature lowering operation. The display device includes a light transmissive liquid crystal display unit disposed on an optical path of light emitted from a light source and a first optical member disposed between the liquid crystal display unit and the light source and configured to change an optical path of light that enters the first optical member from the light source and passes therethrough toward the liquid crystal display unit. The optical sensor is disposed on an optical path of the external light incident on the display device at a side opposite to the liquid crystal display unit across the first optical member. The first optical member includes a passage on an optical path through which the external light passes.

  • Patent number: 10394027
    Abstract: A head-up display system includes an image-forming and projection device, a combiner, a housing, and a lid body. The lid body includes at least a first divided lid body and a second divided lid body which engage with each other at the time of covering an opening of the housing. The first divided lid body includes an optical path regulator that regulates an optical path of projection light of a display image projected from the image-forming and projection device in use of the combiner onto an inner side of the housing, and allows projection light, which is necessary for formation of the virtual image of the display image in the projection light of the display image, to pass through the optical path regulator. The second divided lid body includes a covering member that covers the optical path regulator at the time of covering the opening.

  • Patent number: 10234682
    Abstract: A head-up display device includes: a light source that emits light; a condenser that condenses the light emitted from the light source in a first direction; an adjuster that adjusts the light emitted from the condenser; a first reflector that reflects the light emitted from the adjuster in a second direction different from the first direction; a display that includes an image display surface forming a display image and emits a display light representing the display image with the image display surface transmitting the light reflected by the first reflector; a second reflector that reflects the display light being emitted from the display and being incident from above; and a third reflector that reflects the display light incident from the second reflector to the projection member. The adjuster adjusts the light emitted from the condenser according to a size of the image display surface.
