The comrades on the first floor and the third floor may not know much about electronic devices. There is no real LED screen for home color TV. Because the pixel size of LED screen is too large to be miniaturized in the case of high resolution, it is difficult to enter the field of home TV. The LED TV on the market is actually LCD TV with LED backlight module, while the traditional LCD screen uses CCFL cold cathode lamp. At present, the LCD screen is mainly divided into hard screen and soft screen, generally speaking, hard screen is better than soft screen (the soft and hard here refers to the structure of the screen rather than the touch hardness). As far as the driving circuit structure is concerned, TFT LCD screen is basically used in TV sets. In the market/

As far as the driving circuit structure is concerned, TFT LCD screen is basically used in TV sets. The backlight system of LCD TV in the market is mainly divided into two types: the traditional CCFL cold cathode fluorescent tube and the new LED backlight system. Very few TV sets use hot cathode fluorescent tube. The LED backlight system has higher efficiency and longer service life, and can easily realize regional dynamic control, which is conducive to reducing the light leakage phenomenon of LCD screen, Therefore, the preferred LED backlight color TV..
