What are the general characteristics of LCD displays? LCD displays 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 phosphors, which are displayed by hitting the phosphors with electron beams. The electron beam will produce strong electromagnetic radiation at the moment it hits the phosphor. Although many display products have dealt with radiation issues more effectively and reduced the amount of 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 driving circuit in the display. In order to dissipate heat, the ordinary display must be retained 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.
