20090303158 | HEAD-UP DISPLAY SYSTEM - A head-up display system having a judgment boundary information storage storing judgment boundary information defining judgment area used for judging based on a movement of the driver's eye position whether or not a reflecting angle of the reflector is adjusted, an imaging device imaging an imaging area, an eye position detecting device detecting a driver's eye position in the imaging area based on image information imaged by the imaging device, a judging device judging whether or not a predetermined adjusting condition is satisfied when the eye position detected by the eye position detecting device is outside the judgment boundary, an install state determining device determining an install state of the reflector based on the detected eye position when the judging device judges that the adjusting condition is satisfied, and a reflector adjusting device adjusting the reflector to be in the determined install state. | 12-10-2009 |
20130188259 | HEAD-UP DISPLAY - 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. | 07-25-2013 |
20130188260 | HEAD-UP DISPLAY - 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. | 07-25-2013 |
20140177064 | DISPLAY DEVICE FOR VEHICLE - 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. The deploying and accommodating mechanism includes a restricting unit configured to restrict an inclination, with respect to a prescribed direction, of a surface of the combiner to a predetermined angle of a ghost suppression state at least when the combiner is located at the position of the use state. | 06-26-2014 |
20140184996 | DISPLAY DEVICE FOR VEHICLE - A display device for a vehicle according to the present invention includes a display which emits an emission display light having a polarization plane in a specific direction, an illumination light source which illuminates the display, and a phase difference plate which is disposed facing the display in a state where a fast axis is shifted by a predetermined angle with respect to the polarization plane of the emission display light emitted by the display. | 07-03-2014 |

20120256812 | HEAD-UP DISPLAY DEVICE - 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. | 10-11-2012 |
20120300486 | VEHICLE BACK LIGHT UNIT AND VEHICLE DISPLAY SYSTEM - A high-intensity back light is enabled by satisfying temperature conditions under an on-board environment. | 11-29-2012 |
20130010366 | HEAD-UP DISPLAY DEVICE - A head-up display device which can be applied to various types of vehicles is provided without causing cost increase. A head-up display device which makes a virtual image to be formed by projecting display light on a windshield of a vehicle includes a housing, an indicator which is provided in the housing, and a reflector which is provided in the housing, and includes a plurality of reflecting surfaces which are arranged in parallel with each other and inclined at the same angle so that the display light which is irradiated from the indicator is reflected by the reflecting surfaces. | 01-10-2013 |
20130176335 | VEHICULAR DISPLAY DEVICE AND VEHICULAR DISPLAY SYSTEM - 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. | 07-11-2013 |
