Television Plasma - Overview
The definition of plasma television is a television which the picture processed from a gas (plasma) filled with xenon and neon atoms and millions of electrically charged atoms and electrons at specific intervals. The display itself consists of cells, within each cell two glass panels are separated by a narrow gap in which neon-xenon gas is injected and sealed in plasma form. The charged gas release photons of light green, blue and red phosphors, thus creating a television image. Each group of red, green, and blue phosphors is called a pixel (picture element).
The life time for plasma televisions stated with lifespan rating. It is means that Plasma television will lose approximately 50% of its brightness during its rated lifespan time. Today, Plasma television has 60,000 to 100,000 hours lifespan. If the Plasma television is use for 10 hours a day, the 60,000 hours Plasma television will has lifespan about 16 years.
Advantages of Televisions Plasma
Higher resolution
Plasma televisions have capability of displaying full HDTV and DTV signals as well as XGA, SVGA, all the way up to UWXGA (1920 X 1080) signals from a computer.
Perfectly flat screen
Plasma televisions have perfectly flat screen, this eliminates the edge distortion and allowing the wide viewing angles.
16:9 aspect ratio
Plasma televisions have a widescreen 16:9 aspect ratio, which was originally designed to match the natural field of view of the human eye. The 16:9 aspect ratio is also the chosen format for HDTV content.
No scan lines
Plasma televisions have no scan lines due to the fact that each and every pixel cell has its own transistor electrode. This creates a smooth, evenly lit image across the entire surface of the display
Wide viewing angle
Plasma televisions now have capability viewing angles approaching up to 178°, much better than rear-projection TVs ( below 160°) and LCD displays ( up to 170° recently).
Thin design
Plasma televisions depth is usually measured at around 3 inches on 42" displays and 4" for 50" screens.
Perfect color production
Today’s Plasma televisions can display billions of colors and 1,000,000: 1 contrast ratio, resulting in smooth gradations between even very subtle shades, and an overall picture quality that is extremely lifelike and realistic.
Lowest response time
The time required by pixel on the screen to move from black to white and return conversely is call Response Time and measured in milliseconds (ms). The lower time is better. Compared to LCD tv, Plasma television has lower response time as low as 1 ms (milisecond) which the LCD tv has up to 2 ms.
