LED Backlight Technology from LED LCD TV

  1. A brief introduction to the characteristics of LED TV. LED TV is directly imaged by LED and adopts the principle of active luminescence. The color LED display screen uses R/G/B three LED lamps to form a pixel, and the image display is realized by controlling the on-off of each pixel. The imaging principle is very similar to that of active luminous plasma. There is no backlight circuit inside the LED TV, and the whole set is very thin (about 2cm). The price is higher, so the current sales are much smaller than LCD TVs, and it will take some time to replace LCD TVs.   2. What is LED backlight In principle, LCD is a bit like a roadside advertising light box. After a certain degree of diffusion, the light source behind it shines uniformly on the transparent film with a picture, thus transmitting a bright picture. The LCD panel is like that layer of film, but its picture is changing. Traditional liquid crystal display devices use CCFL (cold cathode fluorescent lamp) as the light source
