Abstract
A back-lighted display arrangement including a soft, compressible opaque light baffle sandwiched between a lamp assembly and a display panel. The light baffle has a grid-like configuration defining a plurality of compartments each of which is arranged to receive a different one of a plurality of lamps supported by the lamp assembly and to direct light emitted by the lamp onto a different one of a plurality of display areas of the display panel. The light baffle establishes a positive light-tight seal between the baffle and the lamp assembly and display panel for preventing light in one compartment from escaping into an adjacent compartment.
