What are the advantages and disadvantages of CRT TV?

With the development of economy, there are more and more kinds of TV sets, among which CRT TV is an early TV product, which used to be very popular with everyone, but now there are not many friends to know. So what are the advantages and disadvantages of CRT TV? What is the principle of CRT TV? Let's take a look together.

What is a cathode ray tube TV?

The structure of CRT TV is a vacuum tube with one or more electron guns inside. An electron beam is emitted by an electron gun. When the electron beam hits the inside of the front screen of the vacuum tube, the luminescent paint on the inside of the screen will produce an image due to the impact of the electron beam. This is how CRT TV works. At present, most thick and bulky TV sets adopt this technology. CRT TV has a long history. After years of innovation and progress, its technology has gradually matured and its image quality has reached a high level. And it is relatively cheap, so the cost performance is still relatively high and better.

What are the advantages and disadvantages of CRT TV?

Advantages of CRT TV: CRT TV is cheaper and more cost-effective. Its color is very bright. If our TV set breaks down, it will be more convenient to maintain and the maintenance cost will be lower.

Disadvantages of CRT TV: CRT TV is bulky, troublesome to move and takes up a lot of desktop space. Its radiation will be larger than that of liquid crystal, so we can't watch it at close range for a long time, otherwise our eyes will be easily affected by radiation and myopia. However, if we watch at a normal distance for a short time, there will be no problem.

What is the principle of CRT TV?

Principle of CRT TV: CRT display (cathode ray tube) is such a device, which mainly consists of five parts: electron gun, deflection coil, shadow mask, high-voltage graphite electrode, phosphor and glass shell. Among them, the most impressive glass shell can also be called fluorescent screen, because its inner surface can display rich color images and clear words.

How does CRT display use the principle of three primary colors? Of course, the three primary colors are not directly painted on the fluorescent screen, but controlled by electron beams. CRT display (called cathode ray tube) is such a device, which is mainly composed of electron gun, deflection coil, shadow mask, high-voltage graphite electrode, fluorescent coating and glass shell. Among them, the most impressive glass shell can also be called fluorescent screen, because its inner surface can display rich color images and clear words.
