What is the difference between liquid crystal LCD and LED?
LCD and LED are two completely different concepts, LCD is the LCD screen, used for display;The LED is a light source device for lighting;
Traditional liquid crystals use CCFL as backlight, compact energy-saving lamps. Now they can use LED as backlight, so they have LED tv.
In fact, the so-called LED TV, relative to CCFL TV, refers to the back light of the liquid crystal. The liquid crystal itself does not emit light and needs an additional light source to shine;
