Plasma Television Technology
Plasma televisions are the latest display technology and the best way to achieve flat panel television displays with excellent image quality and large screen sizes viewable in any environment. Plasma screen televisions are made up of an array of cells, known as pixels, which are composed of 3 sub-pixels, corresponding to the colors red, green and blue.

| Step 1: Address electrode causes gas to change to plasma state. |
Step 2: Gas in plasma state reacts with phosphors in discharge region. |
Step 3: Reaction causes each subpixel to produce red, green, and blue light. |
Gas in a plasma state is used to react with phosphors in each sub-pixel within the television panel to produce colored light (red, green, or blue). These phosphors are the same types used in conventional Cathode Ray Tube (CRT) televisions and computer monitors. You get the rich, dynamic colors you expect. Each subpixel within the plasma television is individually controlled by advanced electronics to produce billions of different colors. All of this means that you get perfect images and exceptional color in a plasma television display that is less than 6 inches thick.
The History of Plasma Television
The concept for plasma television display panels was first conceived in July 1964 at the University of Illinois (USA). The first displays were nothing more than points of light created in laboratory experiments. From then on, the technology was developed and improved and by the late 60's, it had become advanced enough to allow the scientists to construct geometric shapes. Further development was limited, as scientists were restricted by the materials that were available, so plasma screens were small, and image quality was low. Today the progression in high speed digital processing, high-tech materials and advanced manufacturing technology, has made full colour, bright plasma television displays possible in sizes up to 60 inches. Once what was only thought of as Science Fiction is now available and ready to use in a host of new and exciting ways.
