Abstract

Exemplary embodiments provide a lighting system for a transparent LCD having opposing vertical edges, the system having a mullion lighting assembly positioned adjacent to each vertical edge of the transparent LCD, each mullion lighting assembly having sidewalls defining a center channel. A plurality of LEDs are positioned along the sidewall of each mullion assembly and on a side of the sidewall that opposes the center channel. The LEDs are preferably placed in conductive thermal communication with the sidewall and preferably have a quantum dot film positioned over each LED. A fan is preferably positioned to draw cooling air through the center channel.
