Introduction to CRT monitors

A CRT monitor is a monitor that uses a cathode ray tube and is usually a standard part of a computer. Early CRT monitors only had a small green patch, but now 20-inch CRT monitors are common. As the size increases, the display effects of CRT monitors also improve.
CRT monitors, like other hardware devices, often malfunction. However, the investigation found that only about 20% of the failures were actually due to poor quality or natural damage. Most of the failures were caused by poor environmental conditions, improper operation or poor management. It can be seen that environmental conditions and human factors are the main reasons for display failure.
Except for some special occasions, CRT monitors are still used. In most cases, they have been replaced by thin, light, low-power, and low-cost LCD monitors.
With the development of science and technology, the applications of LCDs have become increasingly broad, and they have been widely used in various instruments, calculators, LCD TVs, computers, handheld electronic toys, mobile phones and many other aspects [2]. Although LCD monitors have completely replaced CRTs as the first choice for computer installations, CRT monitors are still required for work in some industries with higher requirements for color reproduction, such as medical and metallurgy.
