What is the difference between LCD liquid crystal display and traditional CRT display?

You must know mobile phone LCD monitors very well, so you may know less about CRT monitors. Where is the biggest difference between the two? What is the difference between LCD LCD screenand traditional CRT monitors? 1. Large viewing area: For displays of the same size, the viewing area of ​​LCD is larger. The viewable area of ​​an LCD monitor is the same size as its diagonal. The approximately one-inch bezel around the front panel of a CRT picture tube cannot be used for the display. 2. High display quality: Since every point of the LCD mobile LCD screen display keeps the same color and brightness after receiving the signal, there is no need to refresh the bright spots like CRT. As a result, the image quality of the LCD monitor is high and flicker-free, keeping eye strain to a minimum. 3. No electromagnetic radiation: The display material of traditional displays is phosphor powder, which is displayed through the impact of electron beams on phosphor powder. When the electron beam hits the phosphor, it produces intense electromagnetic radiation. Although there are many display products that effectively solve the radiation problem, it is very difficult to completely eliminate the radiation. Relatively speaking, mobile LCD screen displays have inherent advantages in radiation protection because they have no radiation at all. In terms of electromagnetic wave protection, mobile LCD screen displays also have their unique advantages. It uses strict sealing technology to seal a small amount of electromagnetic waves in the display drive circuit. In order to dissipate heat, ordinary displays must try to make the internal circuit in contact with the air, so that a large amount of electromagnetic waves generated by the internal circuit can leak.
