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. In low ambient lighting conditions when the back lighting means is lit, the viewer perceives a projection of the opaque graphic symbols and pointer stripes in silhouette against the relatively bright translucent regions of the applique and pointer, respectively.
