The landlord confused the concept of LCDThe abbreviation of liquid crystal is LCD There has never been the concept of LED screen. The LED is actually a light-emitting diode, which has no display function. Square and hospital and other large public places usually use LED as display screen, large volume, large distance, the effect can be imaginedThe so-called "LED screen" is actually a way to mislead consumers. The correct name should be "LED backlight LCD", while the traditional LCD uses light as backlight. LCD itself is different from CRT display principle, it does not actively emit light, need to rely on external light source to illuminate.The advantages of LED are higher brightness, lower power consumption and thinner thickness than traditional backlight. Using LED as backlight will improve the overall brightness and partial contrast. At present, the 100000:1 or even 500000:1 contrast displays announced by major manufacturers use LED as the backlight.The price of LED backlight display is usually more expensive, so the owner can do what he can. Compared with the traditional backlight, the effect of daily use is not significantly improved..
