Why is the LCD screen divided into LED screen and LCD screen?

I believe that LCD mobile LCD screen display '>LCD LCD screenmust be more familiar, then everyone may know less about CRT monitors, where is the biggest difference between the two, the difference between LCD liquid crystal screen and traditional CRT monitor Where is the point? 1. mobile phone LCD mobile LCD screen screen, no electromagnetic radiation: The display material of the traditional display is phosphor powder, which is displayed by electron beam hitting the phosphor powder. The moment the electron beam hits the phosphor powder, it will generate strong electromagnetic radiation. Display products have been dealt with more effectively in dealing with the radiation problem, and the radiation amount has been reduced to the lowest possible level, but it is difficult to completely eliminate it. Relatively speaking, mobile mobile phone LCD screen displays have inherent advantages in preventing radiation, because there is no radiation at all. In terms of electromagnetic wave prevention, liquid crystal displays also have their own unique advantages. It uses strict sealing technology to seal a small amount of electromagnetic waves from the drive circuit in the display. In contact with the air, the electromagnetic waves generated by the internal circuit will 'leak' outward in large quantities. 2. Large viewing area: For displays of the same size, the viewing area of ​​LCD LCD screenis larger. The viewable area of ​​an LCD is the same as its diagonal size. CRT monitors have an inch or so of border around the front panel of the picture tube that cannot be used for display. 3. High display quality: Since each point of the LCD screenkeeps the color and brightness after receiving the signal, it emits light constantly, unlike the cathode ray tube display (CRT), which needs to constantly refresh the bright spots. Therefore, the LCD screen has high picture quality and absolutely no flicker, minimizing eye fatigue. LCD LCD screen LCD LCD screen manufacturer TFT LCD screen
