Working principle Xenon and neon gases atoms having equally
protons & electrons. Appling voltage across it . Due to this positive
charged ions generates in the process of
collision. This releases ultraviolet light , invisible to
human eye.
UV light interact phosphor material and givesvisible light.
Through the pixel colors created on
screen.

Closing thought
How long they last??? As technology has been made better, Plasma screens have a much
longer life and you should expect 30,000 hours of use. In other words
your television would need to be on for 16 hours a day, every day for
the next 5 years. By the time your TV needs replacing higher
definition models will have become available. Most of us should notbe worried as it will give years of enjoyment
Is it Worth Spending Money On?
When the first Plasma televisions were designed for home use you
didn't get much change from $5000 dollars for a basic small model. Asthe technology has improved and production has increased, prices have
been smaller. You can now get a 37 inch model for as little as $1000 or
even less so they are great value. Soon buying a CRT television will be
a thing of the past as the new digital age is upon us.
