Monitor

The monitor is a display system that works in very much the same manner as your television at home. The major component in a monitor is the picture tube that contains a phosphor screen and three electron guns that fire a continuous stream of electrons. When these electrons hit the phosphor screen, it glows and an image is produced when the entire screen is scanned continuously from top to bottom. Monitors are specified by their screen sizes and also by other factors like the maximum resolution that it supports. Newer display systems are now available in the form of TFT and LCD monitors that use the same principles as that of your digital watch.
