液晶背光用冷阴极荧光灯劣化老化原因及对策研究

摘要

冷阴极荧光灯（CCFL）是液晶背光模组的主要部件之一,它的优劣会直接影响背光模组的光学性能。文章较为全面地分析了冷阴极荧光灯亮度衰减的常见原因,并对延长冷阴极荧光灯使用寿命的方法做了深入的研究和总结。%CCFL is one of the main parts in LCD backlight model,it will directly influence the quality of the optical properties of the backlight model.This paper analysis comprehensively the common cause for brightness attenuation of CCFL,study deeply of the method to prolong the service life of CCFL.
