Abstract
A touch panel assembly includes a filter plate having a recessed outer surface, first and second "L"-shaped supports each including a plurality of light-emitting or detecting elements along edges thereof with the "L"-shaped supports positioned adjacent to the inner surface of the filter plate and about the recessed outer surface whereby light from a lamp passes through the recessed outer surface to a detector element. A display is positioned in alignment with the recessed outer surface. The assembly is compact and facilitates the sealing of the display and electronics within a housing. The "L"-shaped supports for the light sources and detectors facilitate the assembly and servicing of the light elements in the assembly.
