Abstract
We commercialized the 37" LCD TV LC37BD5 and LC37BT5 in November, 2002. The 37" LCD TV has screen area about 1.5 times the size of the 30" LCD TV that was the maximum size in the previous model. When only the backlight system which enlarged the conventional system simply was used, the problem arose in the brightness uniformity of a screen, and power consumption was not able to satisfy the demand specification. This paper describes an outline about the super long CCFL (Cold Cathode Fluorescent Lamp) , the twin inverter system and the new material adopted in order to solve these problems.
