1. What is Plasma?
Plasma ?
Plasma is by far the most common form of matter.
Plasma in the stars and in the tenuous space between them makes up over 99% of the
visible universe and perhapsmost of that which is not visible.
Plasma consists of a collection of free-moving electrons and ions - atoms that have lost
electrons.
Energy is needed to strip electrons from atoms to make plasma. The energy can be of
various origins:thermal, electrical, or light (ultraviolet light or intense visible light from a laser).
With insufficient sustaining power, plasmas recombine into neutral gas.Solid ⇒ Liquid ⇒ Gas ⇒ Ion, Electron : The 4th State of Matter

▶ Plasma can be accelerated and steered by electric and magnetic fields which allows
it to be controlled and applied. Plasma research is yielding a greater understanding of
the universe.
It also provides many practical uses: new manufacturing techniques, consumer products,
and the prospect of abundant energy.
Ex.)Lightning, Aurora, Nebula, Flames, Neon Sign, Solar core ….

2.What is Plasma Display Panel(PDP)?
(1) How does it work?
Plasma display panel is the latest display technology and the best way to achieve flat panel displays with
excellent image quality and large screen size that is easily viewable in any environment.
PDP is an array of cells, known as pixels,which are composed of 3 sub-pixels, corresponding to the colors
Red, Green and Blue. Gas in a plasma state is used to react with phosphors in each sub-pixel to produce
colored light (red, green or blue). These phosphors are the same types used in Cathode Ray Tube(CRT)
devices such as televisions and standard computer monitors. You get the rich, dynamic colors that you expect.
Each sub-pixelis individually controlled by advanced electronics to produce over 16 million different colors.
All of this means that you get perfect images that are easily viewable in a display that is less than 6 inches
thick.
