Display for vehicle
First Claim
1. A display for a vehicle comprising:
- an instrument panel disposed between a windshield glass and a driver'"'"'s seat of a vehicle;
a reflecting member disposed on said instrument panel, said reflecting member having a reflecting surface that faces said driver'"'"'s seat;
a light-emitting display means, disposed between said windshield glass and said driver'"'"'s seat of the vehicle, for displaying driving information by emitting light, said display means having a display surface which displays said driving information and which faces said reflecting surface, wherein said driving information is projected onto said reflecting surface from said display surface and reflected from said reflecting surface in the general direction of said driver'"'"'s seat; and
contrast means for controlling the contrast between light-emitting portions of said display surface and non-light-emitting portions of said display surface such that said contrast is sufficiently high as to be visible from said driver'"'"'s seat in the presence of exterior light impinging on said display surface, said contrast means comprising a cover plate of a semi-transmissive material that reduces the brightness intensity of exterior light impinging on said display surface, said cover plate positioned between said display surface and said reflecting member such that exterior light directed toward said display surface is transmitted through said cover plate before impinging on said display surface;
wherein the transmissivity of said semi-transmissive material is changeable such that the intensity of the brightness of said exterior light transmitted through said cover plate is controlled, and the entire driving information projected from said display surface is visible from said driver'"'"'s seat; and
wherein said cover plate is positioned at such an angle with respect to the direction of travel of the exterior light and at such an angle with respect to said reflecting member whereby a substantial portion of the exterior light that is reflected from said cover plate is not projected toward the vicinity of said driver'"'"'s seat.

Abstract
A display for a vehicle arranged such that displays indicating driving information such as engine speeds, water temperatures and so on are disposed in the portion other than the dash board of the vehicle whereby information form the displays can be visibly recognized form the driver'"'"'s seat by projecting the same to a reflecting member disposed in the portion of the instrument panel in the dash board wherein semi-transmissable cover plates are provided on the front surfaces of the displays confornting the reflecting member as to reduce an influence of light from outside of vehicle through the windshield glass, to prevent reduction in the contrast of the display image for the purpose of obtaining a display image exhibiting excellent visibility and quality.

10. A display for a vehicle comprising:
-
an instrument panel disposed between a windshield glass and a driver'"'"'s seat of a vehicle; a reflecting member disposed in said instrument panel and having a reflector surface that faces said driver'"'"'s seat, a steering column cover disposed between said instrument panel and said driver'"'"'s seat, said steering column cover having a display accommodating portion; a light-emitting display means disposed in said display accommodating portion for displaying driving information by emitting light, said display means having a display surface which displays said driving information and which faces said reflecting surface, wherein said driving information is projected onto said reflecting surface from said display surface and is further reflected from said reflecting surface in the general direction of said driver'"'"'s seat; and contrast means for controlling the contrast between light-emitting portions of said display surface and non-light-emitting portions of said display surface such that said contrast is sufficiently high as to be visible form said driver'"'"'s seat in the presence of exterior light impinging on said display surface, said contrast means comprising a cover plate of a semi-transmissive material that reduces the brightness intensity of exterior light impinging on said display surface, said cover plate being positioned between said display surface and said reflecting member such that exterior light directed toward said display surface is transmitted through said cover plate before impinging on said display surface; wherein the transmissivity of said semi-transmissive material is changeable such that the intensity of said exterior light transmitted through said cover plate is controlled, and the entire driving information projected from said display surface is visible from said driver'"'"'s seat and; wherein said cover plate is positioned at such an angle with respect to the direction of travel of the exterior light and at such an angle with respect to said reflecting member whereby a substantial portion of the exterior light that is reflected from said cover plate is not projected toward the vicinity of said driver'"'"'s seat. - View Dependent Claims (11, 12)
