  2. Types Of Monitors:CRT • CRT stands for Cathode Ray Tube. • Both televisions and monitors can be made using CRT technology. • CRT monitors are deeper and wider than their LCD counterparts. • They also have more vivid colors and a longer life • The major components of a CRT monitor are the fluorescent screen and electron guns.

  3. Types Of Monitors:LCD • Liquid Crystal Display • A thin, flat electronic visual display • uses the light modulating properties of liquid crystals. • LCDs are more energy efficient andoffer safer disposal than CRTs. • Its low electrical power consumptionenables it to be used in battery-powered electronic equipment. • It is an electronically-modulated optical device madeup of any number of pixels filled with liquid crystals and arrayed in front of a light source (backlight) or reflector to produce images in color or monochrome.

  4. Types Of Monitors:LED • LED stands for Light Emitted Diode • LED display has a background produce with LED instead of the convectional fluorescent LED • Newest types of computer monitors on the market today.

  5. How A CRT Monitor Works • Cathode-ray tube monitors were the first computer monitors out. • CRT monitors contain millions of tiny red, green, and blue phosphor dots that glow when struck by an electron beam. • A shadow mask is a thin metal screen filled with very small holes. • Three electron beams pass through the holes to focus on a single point on a CRTdisplays' phosphor surface. • The unwanted beams are blocked or "shadowed."

  6. How An LCD Monitor Works • Next step in the line up of computer monitors. • These monitors work by blocking light • An LCD Monitor is made up of two pieces of polarized glass • Electrical currents cause the liquid crystals to align to allow different levels of light to pass through to the second substrate and create the colors and images that you see. • http://static.howstuffworks.com/flash/lcd-twisted.swf • http://www.ehow.com/video_4973278_a-computer-monitor-work.html

  7. How An LeD Monitor Works • Light Emitting Diode displays are the most recent line up of monitors. • The Diode emits light when stimulated by an electrical current, which is known as electroluminescence. • LEDs consist of red, green and blue elements, which combine to create the desired colors. • Advantages of LEDs include lower power requirements • Less-expensive manufacturingprocess, and improvements in contrast and color.

  8. Average Cost OF Monitors • Since LED monitors are the newest of the monitors, they have the highest average cost. • On average a LED monitor can cost from $200 to $400. • A budget-priced LCD monitor can be purchased for about $100to $200. • The average CRT monitors cost as cheap as $50 to somewhere around $200. • CRT monitors are the oldest of the three types of monitors therefore they are the cheapest.
