What is LCD, LED AND PLASMA TV?
LCD: A traditional TV used a cathode ray tube to display images on the screen. LCD TVs use cold cathode fluorescent lights (CCFLs) to illuminate the screen. These TVs are usually the most popular and are most suitable for brightly lit rooms.
LED TVs: This is the new technology – a TV that uses light-emitting diodes (LED) to create the picture we see. LEDs are typically the most energy efficient and are the thinnest TVs out there.
Plasma TV: This was the best kind of TV you could hope to own, but it’s being sidelined now by LCDs and LEDs. A plasma TV display is an array of tiny gas cells sandwiched between two sheets of glass. Each cell acts like a mini fluorescent tube, emitting ultraviolet light which then strikes red, green and blue spots on the screen, which glow to build a picture. Plasmas are the heaviest of all three options, and use more power as well.
