Multiplicity of discharge channels for a flat fluorescent lamp to backlight a full color LCD

A flat fluorescent lamp (FFL) employing segmented closed hollow cathodes generated through a thick-film technique has been developed. The device contains six sets of such hollow electrodes operating in parallel and thus allowing the branching of discharge current through the six channels. Without the use of a diffuser, the brightness uniformity of a 5-in diagonal FFL is 85%.<
