Abstract: An improved vehicle display apparatus in which both the display and pointer are illuminated for low ambient driver viewing by a single electroluminescent (EL) lamp mounted on the rear face of the display. A generally opaque applique includes a translucent region in registry with the active area of the EL lamp, and bright opaque graphic symbols painted or deposited onto a surface of the applique within the translucent region. A pointer disposed in proximity to the front surface of the applique is provided with juxtaposed bright opaque and transparent regions. In high ambient lighting conditions when the EL lamp is not lit, a viewer of the display perceives the bright opaque graphic symbols and pointer stripes against the relatively dark translucent background regions of the applique.

Abstract: An improved vehicle head-up display apparatus in which both the display and pointer of the image source are illuminated for low ambient driver viewing by a back lighting means mounted on the rear face of the display. A generally opaque applique includes a translucent region in registry with the backlit area, and bright opaque graphic symbols painted or deposited onto a surface of the applique wihin the translucent region. A pointer disposed in proximity to the front surface of the applique is provided with juxtaposed bright opaque and transparent regions. In high ambient lighting conditions when the back lighting means is not lit, a front lighting means illuminates the bright opaque graphic symbols and pointer stripes so that a viewer of the projected display perceives an image of the bright opaque graphic symbols and pointer stripes.

Abstract: An improved vehicle display apparatus in which both the display and pointer are illuminated for low ambient driver viewing by a common lightpipe apparatus positioned on the rear face of the display. The display comprises a generally opaque applique having a translucent region in registry with an emissive region of the lightpipe apparatus, and bright opaque graphic symbols painted or deposited onto a surface of the applique within the translucent region. A pointer disposed in proximity to the front surface of the applique is provided with juxtaposed bright opaque and transparent regions. In high ambient lighting conditions when the lightpipe apparatus is not lit, a viewer of the display perceives the bright opaque graphic symbols and pointer stripes against the relatively dark translucent background regions of the applique.
