  • Publication number: 20190033584
    Abstract: A vehicular display apparatus includes a display device, a magnifying mirror, and a turning back mirror. The display device emits display light corresponding to a display image to be visually recognized by a driver on a vehicle. The magnifying mirror reflects the display light to project the display image on a windshield of the vehicle. The turning back mirror is disposed on an optical path between the display device and the magnifying mirror and has a concave reflecting surface that reflects the display light. The magnifying mirror has the magnifying power that is set higher than that of the turning back mirror.

  • Publication number: 20180299674
    Abstract: A vehicle display device includes: a projector that emits display light corresponding to a display image to be visually recognized by a driver of a vehicle; a screen on which the display image corresponding to the display light emitted from the projector is projected and that reflects the display light; and an aspheric mirror reflecting reflection light of the display light reflected by the screen toward a windshield of the vehicle. The aspheric mirror has a non-reflection area on a part of a reflection surface reflecting the reflection light toward the windshield. The projector is arranged at a position facing the screen with the aspheric mirror interposed therebetween such that the display light passes through the non-reflection area and is directed to the screen.

  • Patent number: 9304318
    Abstract: A display device for a vehicle includes a deploying and accommodating mechanism configured to change a state of disposition of a combiner between a position of a use state in which a display can be seen in the observation region and a position of an unused state in which a display cannot be seen in the observation region.

  • Patent number: 9052504
    Abstract: A head-up display includes a display device and a combiner that has a rear surface brought into contact with an inner surface of a windshield of a vehicle, and reflects a display light rays emitted from the display device by a front surface of the combiner toward a driver in the vehicle. The front surface forms a first arc-shaped optical surface which receives and reflects the display light rays toward the driver so that the driver sees a first virtual image of the display light rays with a set magnification greater than 1 on the outside of the windshield. The rear surface forms a second arc-shaped optical surface which receives and reflects the display light ray toward the driver so that the driver sees a second virtual image which coincides with the first virtual image in terms of the size and position on an outside of the windshield.

  • Patent number: 9041740
    Abstract: A vehicular display device includes a display unit that displays visible information and a light projection unit that guides light including the visible information displayed on the display unit to a predetermined projection surface, and displaying the visible information as a virtual image. The vehicular display device includes a guide display unit and a guide display control unit. The guide display unit indicates a relationship between at least positions of a first display region in which the virtual image is displayed by projection of the light projection unit and a second display region in which detailed information is displayed. The detailed information has an association with a content of particular information that is displayed on the display unit under a predetermined condition. The guide display control unit controls the guide display unit into a display state when the particular information is displayed on the display unit.

  • Patent number: 8950868
    Abstract: The head-up display device sequentially displays a virtual image (51V) of a guide light from one end of a reflector (30) side, in the back inside of a virtual image (83V) of an opening bezel formed into a square frame displayed along an outer edge of a projection area (71) of a window shield, and further displays a virtual image (20V) of display information in the back thereof. The amount of travel of the virtual images (51V) of the guide light when the reflector provided in the head-up display device rotates is smaller than the amount of travel of the virtual image (20V) of the display information. Therefore, even if the virtual image (20V) of the display information falls outside the projection area, the virtual images (51V) of the guide light remain in the projection area, and are displayed.

  • Patent number: 8792177
    Abstract: A head-up display includes a first display device, and a second display device which is provided at a position which is different from a position of the first display device. An optical axis identifying device outputs light beams, which are respectively input from the first display device and second display device, in the identical direction. An enlarged-image forming device enlarges respective images which are formed by the light beams which are output from the first display device and the second display device, based on the light beams which are input from the optical axis identifying device, and forms an image by overlapping the images which are enlarged. A moving device moves at least one of the first display device and the second display device along respective optical axis directions thereof.
