Claim 11
Dependent Claim
329 words
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.
