What is Televisions Plasma?
By Bram P
Since the technology of visual devices rapidly increased in last decades, from CRT (cathode ray tube) television as the first generation of television, LCD (liquid crystal display) and plasma television. In this article is about to explain for plasma television.
Televisions Plasma
The short definition of plasma television is a television which created picture 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 red, green, and blue 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. In the early time Plasma televisions have 30,000 hours lifespan rated, due to technology improvements Plasma televisions now have 60,000 to 100,000 hours. Based on even the modest early 30,000 hour rating, if such a Plasma television is on for 8 hours a day, its lifespan would be about 9 years - or, if on 4 hours a day, the lifespan would be about 18 years (double these figures for a 60,000 hour lifespan).
Advantages of Televisions Plasma
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.
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.
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).
Slim 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
Response time represents the time taken by a pixel on the screen to move from black to white and return conversely and measured in milliseconds (ms). The lower time is better. The result is superb quality of output especially while watching fast moving sequences like sport events or action movies is attributed to this remarkable phenomenon. Today’s Plasma televisions have response time as low as 1 ms (milliseconds) compared to today’s LCD televisions which have up to 2 ms.
