CRT Monitor
A CRT monitor is a desktop monitor that contains a cathode-ray tube. A cathode-ray tube (CRT) is a large, sealed glass tube. The front of the tube is the screen. A CRT’s viewable size is the diagonal measurement of the actual viewing area provided by the screen in the CRT monitor. A 21-inch monitor, for example, may have a viewable size of 20 inches.
CRT monitors produce a small amount of electromagnetic radiation. Electromagnetic radiation (EMR) is a magnetic field that travels at the speed of light. Excessive amounts of EMR can pose a health risk. To be safe, all high-quality CRT monitors comply with a set of standards that defines acceptable levels of EMR for a monitor. To protect yourself even further, sit at arm’s length from the CRT monitor because EMR travels only a short distance.
LCD Monitor
An LCD monitor is a desktop monitor that uses a liquid crystal display to produce images. These monitors produce sharp, flicker-free images. LCD monitors have a small footprint; that is, they do not take up much desk space.
