Structure and energy consumption for several types of cold cathode fluorescent lamp backlight are analyzed. 分析了国内外几代典型的冷阴极荧光灯(CCFL)背光源的结构以及能量损耗情况。
Several types of LCD backlight, including their work principle and new development, are briefly introduced. These LCD are Cold Cathode Fluorescent Lamp(CCFL) ( CCFL ), Electroluminance ( EL ), Light-Emitting Diode ( LED ). 文中简述几种常见的LCD背光源,包括其各自的优缺点与最新进展,其中包括冷阴极荧光灯(CCFL)(CCFL)、电致发光器(EL)和发光二极管(LED)。
In all types of FPD, Liquid Crystal Display ( LCD ) occupies a dominant position. In a long time, as an important part of LCD, backlight mainly uses Cold Cathode Fluorescent Lamp(CCFL). 背光源作为液晶显示屏中的重要组成部分,长期以来主要使用的是冷阴极荧光管。
When the electro-magnetic transformer is used in the cold cathode fluorescent lamp ( CCFL ) driver, the transformer is very easy to be broken, the EMI and the power lose is very serious, and the weight and volume is hard to be minimized. 电磁式变压器用于冷阴极管驱动器时易被击穿,电磁干扰严重,功率损耗较大,难以使驱动器实现平面化和轻量化。
