Abstract: High luminance display devices, typically utilized in applications requiring sunlight readability, require unique design methodologies as the thickness approaches a maximum of one-inch. The present invention relates to a high intensity light generation engine (20, 920) and associated light transmission apparatus (30, 42, 40) for transmitting the light generated by the engine to a remote location. The invention is especially applicable for use in constructing a back lighted display (80), such as a liquid crystal display (LCD), of minimal thickness, i.e., one-inch or less. A display (80) of minimal thickness is achieved by separating the light source (12) and other peripherals (from the display device (80), using a remote enclosure (900)). Such a display (80) is most suited for use in high ambient lighting conditions where space is at a premium, such as in the cockpit of an aircraft.

Abstract: A process for making a protective and decorative surfacing film comprises extrusion coating a solventless polymeric material from an extruder die to form an optically clear first layer on a polyester carrier sheet travelling past the extruder die opening. The extrusion coated first layer is immediately cooled on the carrier sheet to harden it, followe d by applying a pigmented second layer to the first layer. The composite paint coat is transferred to a reinforcing backing sheet, after which the carrier sheet is separated from the paint coat to expose the outer surface of the first layer as a high gloss surface with a high distinctness-of-image, providing a transparent protective outer coat for the pigmented second layer. The pigmented second layer can be solvent cast and dried or extruded and hardened as a separate coating on the fist layer. The composite paint coat can be bonded to a coextruded size coat and semi-rigid plastic substrate panel to form a thermoformable laminate. Techniques are disclosed for producing extruded clear films of exceedingly high optical clarity using a closed air flow transport and HEPA filtration system that removes airborne particles from the resin handling and extrusion process, thereby preventing micron-sized contaminants naturally present from many sources from entering the process a nd degrading ultimate film quality.
