MONITOR

Is a video display screen and the hard shell that holds it. In its most common usage, monitor refers only to devices that contain no electronic equipment other than what is essentially needed to display and adjust the characteristics of an image.

                     TYPES OF MONITOR

CRT MONITOR

                                               

Cathode Ray Tube, or in simpler words CRT, are oldest among all available models these days. These monitors function on the old cathode ray tube phenomena.These monitors allow the use of external devices like light pens and light guns. One of the drawbacks of these monitors is their weight and another is their size. 

LCD MONITOR

            

                                             

Liquid crystal display monitors are not the latest but the later version than CRT monitors. Unlike CRT monitors, these monitors are compact and slim.These monitors do consume low and almost have no dependency on backlight technology. Due to its quality of consuming low power and compact in shape and size, it has been well adapted in the time when energy efficiency is the main concern.

PLASMA MONITOR


                                                 

Plasma screen and/or plasma monitors are considered as high contrast screen with bright, vibrant colors and brightness that claims to make your visual experience worthwhile.It works on plasma discharge on almost ideally flat panel of glass. The discharge is composed of xenon and neon without any use of mercury in it.  Plasma monitors are in, mainly because of their excellent and remarkable viewing angles, color saturation, and contrasts.



SED MONITORS

                                       

SED is abbreviated form of Surface-conducted electron-emitted display. These are high resolution and flat penal display screens. Some of these display units are even more than 40 inches in diagonal measurements.

These display units are composed from an electron-emitting array and layer of phosphorus. Array and layer of phosphorus are separated by thin sheet that allows air to pass. SED consumes less energy in comparison with CRT and it gives higher resolution picture.
