Cathode Ray Tube (CRT) monitor is abbreviated as CRT.
CRT monitor is known as Cathode Ray Tube (CRT), which is a kind of monitor using Cathode Ray Tube (CRT). There are five main components: electron gun (Electron Gun), deflection coils (Deflection coils), shade (Shadow mask), high-voltage graphite electrodes and phosphor coating (Phosphor) and glass shell.
A CRT monitor is a type of display that uses a cathode ray tube (CathodeRayTube), which is usually part of the standard equipment of a computer. Early CRT monitors were only a small green color, while today 20-inch CRT monitors are commonplace. As the size has increased, so has the display of CRT monitors.
Principle of operation: CRT monitors rely on an electron beam to excite the phosphor on the inner surface of the screen to display the image, and because the phosphor is lit up and then quickly goes out, the electron gun must cycle through the dots and keep exciting them.
CRT monitors, like other hardware devices, often fail. However, the survey found that the real due to poor quality or natural damage to the failure of only about 20%, most of the failure is due to poor environmental conditions and improper operation or mismanagement. It can be seen that environmental conditions and human factors are the main cause of display failure.
In addition to some special occasions are still using CRT monitors, in the vast majority of occasions, it has been thin, low-power, low-cost liquid crystal display replaced. With the development of science and technology, the application of liquid crystal display is increasingly broad, has been widely used in a variety of meters, calculators, LCD TV, computers, handheld electronic toys, cell phones and many other aspects.
While LCD monitors have fully replaced CRTs as the preferred choice for computer installations, some industries with high color reproduction requirements, such as medical and metallurgical, still need to use CRT monitors for their operations.
