The meaning of LED is light emitting diode. In general LCD TV, the LCD monitor will not emit light on the LCD panel itself according to the principle of light emission. They need a lighting system. The general backlight lighting system of liquid crystal display uses six U-shaped tubes to stop lighting, while the backlight lighting system of LED TV uses several light-emitting diodes to stop lighting. Because the task current of light-emitting diodes is relatively much smaller and the brightness is much larger. Therefore, it is much more energy-saving related to the new U-tube TV display, and the life of the lighting system of LED TV is much longer. Moreover, due to the increase of illumination, the color saturation and brightness of the TV set are much larger. The image is very bright. 20 1 1- 10-24 1 1:59: 12
