What is an LCD display and what are the characteristics of an LCD display?

LCD display is also called liquid crystal display. The English abbreviation is LCD. The full name is Liquid Crystal Display, which is a type of flat panel display. Used for TV and computer screen display. The LCD display has the advantages of low power consumption, small size and low radiation. The LCD liquid crystal display uses a three-layer structure in which two pieces of electrode materials contain a solution of liquid crystal molecules, and when the current passes through the liquid, the molecules are rearranged to achieve imaging purposes.

 

The LCD display uses two pieces of polarized material with a liquid solution between them. When an electric current passes through the liquid, the molecules are rearranged so that light cannot pass through them. Therefore, liquid crystal molecules allow both light to pass through and block light. At present, liquid crystal display (LCD) products are developing towards light, thin, short and small targets.

 

What is lcd display

 

Traditional display methods, such as CRT picture tube displays and LED display panels, are affected by factors such as volume and high power consumption, and cannot meet actual needs. The development of liquid crystal display technology is just in line with the current trend of information products. LCD liquid crystal display has the advantages of right-angle display, low power consumption, small size, zero radiation, etc., allowing users to have the best visual environment.

 

At present, liquid crystal display technology is mainly divided into three technologies: TN, STN, and TFT. TN type liquid crystal display technology is the most basic technology of liquid crystal display, and other types of liquid crystal display screens can also be said to be improved based on the TN type as the origin.

 

TFT-type liquid crystal displays are relatively complicated, and the main components include fluorescent tubes, light guide plates, polarizing plates, filter plates, glass liquid crystal display glass substrates, alignment films, liquid crystal materials, thin-mode transistors, and so on.

 

LCD LCD display advantages

 

One, thin, does not occupy space.

 

Second, there is no radiation, which is good for health.

 

3. No flicker, good for eyes.

 

Fourth, low energy consumption and energy saving.

 

Five, completely flat, without visual distortion.

Disadvantages of LCD screen

 

First, there are limitations on viewing angles.

 

Second, there is a response speed, which will cause the screen smear.

 

Third, the degree of color reproduction and authenticity can also be improved.

 

Fourth, the brightness is limited.
