Abstract
An instrument panel assembly (10) having a transparent intermediate substrate (42) inside its housing (16) on which is applied a phosphor coated indicia (40) for giving the appearance of a depth dimension when energized by a UV light source (36). Multiple intermediate substrates (42, 48) can be positioned at different level within the interior region of the housing (16), each containing various indicia (40, 46, 56, 58) which emits luminescent light when irradiated by the UV light source (36). Multiple UV light sources (36, 52) can be set to project UV radiation of different wavelengths into the housing (16) with each of the phosphor coated indicia (40, 46, 56, 58) being selected from material types which are responsive to only one of the various UV wavelengths, so that each indicia (40, 46, 56, 58) can be selectively energized to display warnings, information messages, or the like.
