Abstract
An integrated liquid crystal display and backlight system for generating video images for a portable computer (12) comprising a top glass (32), a bottom glass (34) and a thin film transistor and liquid crystal layer (36) disposed therebetween, a diffuser (38) bonded to the bottom glass (34) on the side opposite the top glass (32), a substrate (40) bonded to the diffuser (38) opposite the bottom glass (34) having an array of semispherical cavities (42) each having an aluminized surface (44), a phosphor layer (46) coating the aluminized surfaces (44), an array of indium tin oxide conductors (48) electrically connected to the aluminized surfaces (44) and disposed within the cavities (42), and a volume of mercury gas (50) filling the cavities (42) such that when a voltage (54) is established between the aluminized surfaces (44) and the indium tin oxide conductors (48), the phosphor (46) becomes excited and produces backlight for the liquid crystal display system (26).
