What's the difference between LED backlight and LCD? What are they made of?
LED backlight life than EL long (over 5000 hours), and the use of DC voltage, usually used in small monochrome display, such as telephone, remote control, microwave oven, air conditioning, instrumentation, stereo audio equipment etc.. However, its brightness is not enough at present, for large transmission displays provide back light sources. LED backlight and CCFL backlight structure is basically the same, the main difference is that LED is a point light source, and CCFL is a line light source.
LCD is a non luminescent display device that requires a backlight to achieve the display function. In addition to the performance of the backlight, the quality of LCD imaging is directly affected. The cost of the backlight source accounts for 3-5% of the LCD module, and the power consumed is more than 75% of the module. It can be regarded as a very important component in the LCD module. High precision and large size LCD backlight technology must have high performance and match, so when the LCD industry efforts to develop new applications and high performance of the backlight technology (such as high brightness, low cost, low power consumption, light etc.) also plays a backstage role
The backlight (BackLight) is a light source behind the liquid crystal display (LCD), and its luminous effect will directly affect the visual effects of the liquid crystal display module (LCM). The LCD itself does not emit light; it displays graphics or characters as a result of modulation of light.
