Types of Monitors!

 

Types of Monitors:

There are three types of computer monitors, such as:
➤ Liquid Crystal Display (LCD)
➤ Cathode Ray Tube (CRT)
➤ Light Emitting Diode (LED)
Liquid Crystal Display (LCD):
The LCD monitor incorporates one of the most advanced technologies available today. Typically, it consists of a layer of color or monochrome pixels arranged schematically between a couple of transparent electrodes and two polarizing filters. Optical effect is made possible by polarizing the light in varied amounts and making it pass through the liquid crystal layer.
The advantages of LCD monitors include their compact size which makes them lightweight. They also don’t consume much electricity as CRT monitors, and can be run off of batteries which makes them ideal for laptops.
Cathode Ray Tube (CRT):
These monitors employ CRT technology, which was used most commonly in the manufacturing of television screens. With these monitors, a stream of intense high energy electrons is used to form images on a fluorescent screen. A cathode ray tube is basically a vacuum tube containing an electron gun at one end and a fluorescent screen at another end.
Light Emitting Diode (LED):
LED monitors are the latest types of monitors on the market today. These are flat panel, or slightly curved displays which make use of light-emitting diodes for back-lighting, instead of cold cathode fluorescent (CCFL) back-lighting used in LCDs. LED monitors are said to use much lesser power than CRT and LCD and are considered far more environmentally friendly.
