A headup display apparatus consists of a projection optical system unit installed in the dashboard of a car and a reflection member on the windshield. The projection optical system unit contains an indicator and an off-axis reflective hologram which reflects display light of the indicator toward the windshield, which in turn reflects it toward the viewing point of a driver. As a result, the display is seen superimposed on the exterior view. When external light as from the sun enters the projection optical system unit traveling in a direction reverse to the path of the display light, the off-axis reflective hologram reflects the incident external light toward a direction different from that of the outgoing display light to minimize an abnormal illumination of the indicator surface which would otherwise render the display unrecognizable. Behind the hologram is installed a heat dissipating member that receives infrared rays that have transmitted the hologram in order to dissipate heat.

Headup display apparatus

The present invention is directed to a display apparatus which can display information well and does not compromise the feel of a helmet in which the display apparatus is incorporated. The helmet has a front opening formed therein and has a transparent shield mounted thereon so as to cover the front opening. The display apparatus incorporates a display unit disposed on the inner side of the helmet for displaying information thereon. Display light from the display unit is reflected toward a visual point position by an inner face of the shield so that an observer visually observes a virtual image of the display information of the display unit from within the helmet through the shield. The display unit is disposed on the inner side of a chin portion of the helmet so as to not to create any obstruction to the observer.

Display apparatus

The automotive headup display apparatus contains an indicator and a reflection member and has an opening directed toward a reflection surface as on a windshield. A Fresnel lens is installed in the opening for enlarging a display image of the indicator. The reflection member is disposed facing and between the indicator and the reflection surface. The reflection member is coated with a hologram emulsion layer to have a wavelength selection capability such that only the rays of light with almost the same wavelength as display light of the indicator are reflected by the reflection membeer. With this arrangement, when external light should enter the indicator unit from the reflection surface on the windshield, those rays of light different in wavelength from the display light are not reflected toward the indicator, preventing the display of the indicator from being obscured as in the conventional apparatus.

Automotive headup display apparatus

In one embodiment of the present invention, the automotive display apparatus has two concave mirrors arranged below the windshield in such a way that light from the display of an indicator which shows driving condition information such as car speed is reflected by one of the concave mirrors toward the other concave mirror, which then reflects the light toward the windshield that further directs it toward the driver's seat. A drive can thus see a remotely formed virtual display image within a viewing field of the windshield. The first concave mirror, which directly receives light from the indicator and reflects it toward the second concave mirror, is mounted on a plane mirror in such a manner that it can be moved into or out of a light path that extends from the indicator to the second concave mirror. When the first concave mirror is in the light path, the display image is magnified and hence the virtual display image is formed at a remote position from the driver. When the first concave mirror is moved out of the light path, the light is simply reflected by the plane mirror and not magnified so that the virtual display image is formed at a position closer to the driver than the first position. The virtual image position is changed according to the car speed. Other embodiments of the invention include mounting the automotive display apparatus on the ceiling of the vehicle.

In a head-up display such that display images of instruments within a dashboard can be projected upon part of a windshield of an automotive vehicle, the holographic head-up display apparatus comprises a light emitting display unit; a transmissive hologram plate; and a reflective hologram plate. Since visible display images can be seen by the driver after having been passed through the transmissive hologram plate and reflected from the reflective hologram plate, blur of the display image due to chromatic aberration can be cancelled out, thus providing clear head-up instrument images.
