(2)背光源的分类常用的背光源主要有CCFL、LED和EL3种。CCFL背光源也称冷阴极荧光管背光源,是液晶显示器、液晶彩电应用最为广泛的一种背光源,它由冷阴极荧光管发光,通过散射器将光均匀分散在液晶显示屏的视窗区。CCFL背光源能够提供能耗低、光亮强的白光,具有成本低、效率高、寿命长、工作稳定、亮度调节简单、技术成热等优点,但CCFL,需要一个逆变器来供应600～1000 V的交流电源,且亮度不够均匀。
(2) backlight classification Commonly used backlight CCFL, LED and EL3 species. CCFL backlight, also known as cold cathode fluorescent tube backlight, is the most widely used liquid crystal display, LCD color TV backlight, which is cold cathode fluorescent tube light through the diffuser will light evenly dispersed in the liquid crystal display window area. CCFL backlight can provide low energy consumption, bright white light, with the advantages of low cost, high efficiency, long life, stable operation, simple brightness adjustment, technology into heat, etc., but CCFL requires an inverter to supply 600 ~ 1000 V AC power, and the brightness is not uniform enough.
