Very Basic of Plasma TV

• The plasma display panel was invented at the University of Illinoise at Urbana-Champaign by Donald L Bitzer and H. Gene Slottow in 1964.
• Plasma displays are bright (1000 lx or higher for the module), have a wide color gamut, and can be produced in fairly large sizes, up to 262 cm (103 inches) diagonally.
• Plasma television is a flat surface made with millions of tiny glass bubbles.
• Each bubbles contains plasma with phosphor coating. You can assume each bubble as pixel.
• Each pixel-bubble as having three sub-pixels - one red, one green, one blue. When it is time to display an image signal (RGB or video)
• A digitally controlled electric current flows through the flat screen, causing the plasma inside designated bubbles to give off ultraviolet rays. This light in turn causes the phosphor coatings to glow the appropriate color making your Plasma TV provide the best video image anywhere.
• This technology known as "plasmavision".
• Each subpixel is individually controlled by advanced electronics to produce over 16 million different colors. You get perfect images that are easily viewable in a display that is less than 4 inches thick.
• A Plasma Display is a television monitor, capable of displaying high definition TV, regular TV, and home video. AND it's a computer monitor, capable of doing everything a regular computer monitor can do. Just bigger and better.
• The lifetime of the latest generation of plasma displays is estimated at 60,000 hours of actual display time. More precisely, this is the estimated half life of the display, the point where the picture has degraded to half of its original brightness, which is considered the end of the functional life of the display.
• The main advantage of plasma display technology is that a very wide screen can be produced using extremely thin materials. Since each pixel is lit individually, the image is very bright and has a wide viewing angle.
