Plasma HDTV

Plasma televisions are based on a new technology that utilizes a unique display panel that alleviates the need for a cathode-ray picture tube. One of the major benefits of buying these televisions is that they are sized to accommodate new HDTV 16:9 aspect ratios and have a similar pixel resolution to a personal computer monitor. This provides the product the maximum picture clarity. In other words, a plasma display has an emissive flat panel display in which light is created by phosphors that are excited by a plasma discharge between two flat panels of glass. The gas discharge contains no mercury, but instead has a mixture of noble gases. One of the basic things that the plasma screen does is illuminate the tiny colored fluorescent lights to form an image. Three fluorescent lights are red, green and blue, and constitute each pixel.

Plasma is stated to be the "Fourth State of Matter", after solid, liquid and gas. It is considered a distinct state of matter that contains a significant number of electrically charged particles. The number is sufficient to affect its electrical properties and behavior. Plasmas constitute more than 99 percent of the visible universe.

Although the prices of plasma televisions have come down recently, trade analysts predict that the prices will continue to fall just as the prices of any other electronic item. With small companies creeping into the market, competition has now become stiff. Chinese manufacturers are producing these televisions at the cheapest rate, thus taking competition to another level. Akai, Hitachi, LG, Philips, Sony and Samsung are some of the big manufacturing companies producing plasma televisions for global markets. Panasonic and Pioneer are the best-known in the industry and run neck-to-neck in reviews and manufacturing.
