You need a backlight. This backlight, formerly CCFL (cold cathode ray tube), is now white LED. Such as LCD TV.The manufacturing process of the two is not the same, there is no connection( Specific structure principle of each can baidu, need not repeat.. Led refers to the light emitting diode (LED), and we say the LED refers to the liquid crystal display with LED as the light source.LCD refers to liquid crystal display, which uses CCFL (cold cathode fluorescent lamp) as light source. They use different backlights.The thickness of LCD with LED backlight will be further reduced, with longer service life, lower power consumption, more environmental protection, and better color expression of LED backlight screen.
