What are the general characteristics of an LCD display? LCD monitors are also known as liquid crystal displays. The English abbreviation of LCD is Liquid Crystal Display, which is a kind of flat panel display. LCD displays use a liquid crystal solution of two sheets of polarizing material. When an electric current is passed through the liquid, the crystals rearrange for imaging purposes.

 

The main features of the LCD display are as follows:

 

1. The resolution of the LCD display can be very high, and the ppi (pixels per inch) of a general mobile phone can reach more than 300.

 

2. LCD has more gray levels and can display a wider range of colors.

 

3. High display quality: Since every point of the LCD screen maintains that color and brightness after receiving a signal, it emits constant light, unlike a cathode ray tube display (CRT) that needs to constantly refresh the bright points. As a result, the LCD monitor has high image quality and never flickers, minimizing eye strain.

 

4. No electromagnetic radiation: The display material of traditional display screens is phosphor powder, which is displayed by electron beams striking phosphor powder. The moment the electron beam hits the phosphor, it will generate strong electromagnetic radiation. Although many display products have dealt with the radiation problem more effectively and reduced the radiation as much as possible, it is difficult to completely eliminate it. Relatively speaking, LCD screens have inherent advantages in radiation protection, because there is no radiation at all. In terms of anti-electromagnetic waves, LCD screens 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 order to dissipate heat, it is necessary to keep the ordinary display as much as possible. The circuit is in contact with the air, so a large amount of electromagnetic waves generated by the internal circuit "leak" to the outside.
