Provided are an apparatus and a method for manufacturing a flat fluorescent lamp. The fluorescent lamp includes a plurality of discharge channels, a gas inlet connecting to the discharge channels, and an exhaust pipe connecting to the gas inlet. The process for manufacturing the fluorescent lamp includes exhausting air from the discharge channels through the exhaust pipe, diffusing a mercury vapor within the discharge channels, blocking a passage between the gas inlet and the most outer channel, and removing the gas inlet and the exhaust pipe.

Method and apparatus for manufacturing a flat fluorescent lamp

An external electrode surface emission fluorescent lamp for LCD backlighting includes (a) a serpentine-shaped upper sheet having a section for maximizing brightness uniformity within a predetermined distance from its surface; (b) a plate-shaped lower sheet combined with the upper sheet to form mutually connected channels; (c) external electrodes installed on surfaces of both ends of the upper sheet; and (d) auxiliary electrodes installed along the surface of channels.
