What is LCD?

LCD is the abbreviation of Liquid Crystal Display, which is a flat-panel display technology widely used in display screens of televisions, computer monitors, instrument panels, aircraft cockpits, and many other electronic devices.

The working principle of LCD is to use the characteristics of liquid crystal molecules to change the arrangement of liquid crystal molecules, thereby affecting the light propagation of the liquid crystal layer to achieve image display. Compared with traditional CRT (cathode ray tube) displays, LCD has the advantages of lower power consumption, thinner form and higher display quality.

LCD monitors have the following characteristics:

1. Small size and light weight: The thickness of LCD is generally only 10% of CRT, and the weight is also greatly reduced, making it easy to carry and install.

2. Low power consumption: LCD’s power consumption is only about 20% of CRT, which is energy-saving and environmentally friendly.

3. Small radiation: LCD does not have cathode rays like CRT, so the radiation is very small and does little harm to the human body.

4. High display quality: LCD has clear pictures, rich colors, large viewing angles, and does not flicker like CRT, so it is less harmful to the eyes.
