The Fundamentals of Plasma TV
Plasma TV, also known as Digital TV, High-definition TV (HDTV), and Plasma Display, is a flat panel television composed mainly of phosphors (chemicals that emit light when mixed with other lights) and plasma (the main element of a fluorescent light). These two compound elements are placed in between the flat glass panels. Plasma TV also contains noble gases that are used as backlights. Unlike mercury, these gases (neon and xenon) are not harmful to human health. Plasma TV works exaclty the same as CRT (cathode ray tube) TV except that the former uses light gases to emit pictures.
In 1964, two University of Illinois scientists; namely Donald L. Bitzer and H. Gene Slottow, invented the first ever Plasma TV for PLATO Computer System. In the following years, plasma TV gained a huge popularity because of its rugged display. In 1993, Fujitsu General (a Japanese-based company) originated the 3-color plasma TV.
Plasma TV is known for its superior picture resolution, no scan lines characteristic, outstanding color accuracy (in fact, plasma TV displays approximately 17 million colors), widescreen feature ratio, flawless flat screen, consistent screen brightness, slim design, extensive viewing angle, and collective display capability.
Plasma TV is use primarily as a business appliance or simply as a home entertainment device. Some of its uses are in the areas of home theater system, network control rooms, administrative and managerial offices, reception entrance halls, meeting and convention rooms, digital signage and billboards, touch screen monitors, and video conferencing.
