In recent years, the backlight of liquid crystal display device is provided from the light emitting diode to provided by the lighting lamp, this new type of lighting method is increasingly out of now, we live in. So, light-emitting diodes (leds) compared with the traditional method of lighting, what are the strengths, it is how to provide lighting for us?
