1. What is Plasma?
Plasma can be accelerated and steered by electric and magnetic fields which allowsit to be controlled and applied. Plasma research is yielding a greater understanding ofthe 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 Ex.) Lightning, Aurora, Nebula, Flames, Neon Sign, Solar core ..
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 thevisible universe and perhaps most of that which is not visible.
Plasma consists of a collection of free-moving electrons and ions - atoms that have lostelectrons. Energy is needed to strip electrons from atoms to make plasma. The energy can be ofvarious origins:thermal, electrical, or light (ultraviolet light or intense visible light from a laser). With insufficient sustaining power, plasmas recombine into neutral gas.

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-pixel is 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.

SUGGGESTIONS
1. Static precautionDrive section circuit is C-MOS circuit, so to protect against static electricity, wear static-proof wrist band.
2. Cleaningwhen wiping panel, do not use liquid cleaner or other chemicals . Use a damp cloth for cleaning .
3. handlingColor PDP uses high voltage(Max.500V). Be aware of electronic shock when handling PDP Unit and dont touch drive circuit.and even driver circuits capacitor is turned off but charge still remains there, so to touch drive circuit, be sure to wait at least 1 minute.
4. Warning when connecting signal & Power Connector in operationdo not touch connector while Color PDP is operating.
5. PDP servicing and guaranteeGlass Panel and Drive Circuit section are linked and operating together.if you disassemble and assemble the product in your own hands , LGE is exempted from the guarantee of function, quality and etc.
6. Damage in still imageColor PDP uses fluorescent material. The quality of PDP fluorescence by nature becomes deteriorated if using it in the same condition of CRT.To prevent this symptom, input full-screen regularly or use screensaver software.So do not display the still image for a long time.
7. Temperature & ventilationColor PDPs Glass Panel section and Drive circuit section emit the heat so the temperature shall be kept under 40.the temperature of glass panel section is pretty high because built-in drive circuit emits the heat.PDP is operating with high voltage therefore be sure to keep it away from conductive objects.
8. Warning when handling Module be aware that PDP shall not be touched by metal or hard objects and shocked by the heat or mechanical force.be careful when disassembling or handling.be sure to wear glove for preventing injury when the glasss broken.
Color PDP is a display device consisting of Panel section & Drive section. Panel section is composed of electrode, fluorescent substances ,dielectrics and gases, and drive section is a combination of electrical circuit section and PCB section. We call this concrete as PDP Module Assy and the following shows warning.

Service warning
1. One DVM ( FLUKE 87 or similar type )2. Digital Oscilloscope ( over 200MHZ )
Defect diagnosis tool
1. When inserting parts or PCB, fasten the lead line to terminal before soldering. 2. When inserting high- voltage resistance(metal oxide film resistance or metal film resistance), keep 10mm away from PCB 3. High-voltage or high-temperature parts shall be away from the lead line.4. This chassis is insulation(cold) chassis but for safety, it is better to use insulation trance.
when servicing power board, be sure to use insulation trance.5. While PDP Module is in operation, do not connect or remove lines.
With COF or panel defect, report it to LGE PDP module service department.

Lift up the right and left of X-BOARD CONNECTOR. Lift up X-BOARD CONNECTOR and separate COP CONNECTOR by pulling up.
When you handle COF CONNECTOR, dont pressure. First release LOCK and separate.If COF CONNECTOR is damaged, you should replace MODULE ASSY. So, be aware of this!!
1) X - Board COF Connector separation
When you exchange X-Board, first you should separate COF Connector. Be careful to handle it.COF Connector is attached to Module. When COF Connector is broken, Module ASSY must be replaced a new one.
