The liquid crystal display(LCD) TV market has been growing continuously and cost reduction is one of the biggest issues to increase its market share. The LCD needs backlight because it belongs to non emissive displays. The cold cathode fluorescent lamp (CCFL) and external electrode fluorescent lamp (EEFL) are widely used in backlight system for LCDs. But assembly of CCFL and EEFL backlight system is very complex. The flat fluorescent lamp (FFL) is a newly developed light source and it has a very simple structure. The LCD backlight can have a simple structure if the newly delvelop FFL is used as a light source. The backlight with FFL can be more cost effective than that of the backlights with CCFL or EEFL light sources. But the temperature behaviour of FFL backlights are different from the backlight with CCFL or EEFL light sources, which prohibits FFL backlight from being accepted as the backlight for commercial application.
