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.
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. LCD monitors are available in a variety of sizes, with the more common being 19, 20, 22, 24, 26, 27, and 30 inches — some are 45 or 65 inches. Most are widescreen, which are wider than they are tall. You measure a monitor the same way you measure a television, that is, diagonally from one corner to the other.
Mobile computers and mobile devices often have built-in LCD screens. Many are widescreen; some are touch screen. Notebook computer screens are available in a variety of sizes, with the more common being 14.1, 15.4, 17, and 20.1 inches. Netbook screens typically range in size from 8.9 inches to 12.1 inches, and Tablet PC screens range from 8.4 inches to 14.1 inches. Portable media players usually have screen sizes from 1.5 inches to 3.5 inches. On smart phones, screen sizes range from 2.5 inches to 4.1 inches. Digital camera screen sizes usually range from 2.5 inches to 4 inches.
