PLASMA Overview

Structure of PDP module

Operation Principle
# PLASMA MODULE has PANEL part and DRIVE part.
Panel : Electrode, Phosphor, Dielectrics, Gas. Drive : Electronic circuit & PCB. (X , Y-sus, Z sus, Y drv,PSU,CTRL B/D)

Safety & Handling Regulations
1. About 10 minute preparation is required before adjustment. 2. Higher voltage than is required for the product shouldnt be applied.

Safety Rules

3. Be cautious of electric shock for PDP module since PDP module uses high voltage, and it is recommended that should one touch the drive circuit after one minute because of residual current. 4. Circuit drive has c-mos circuit which should be protected from static electricity. 5. Module must be carried by two people. 6. Be careful of short circuit when measuring voltage. 7. Be cautious of screws and other metal objects to pervent short in circuit part.
Checking Point before Requesting MODULE Repair
1. Check the appearance of Panel and board. 2. Check the model label if model names and board model matches. 3. Check details of defective condition and history. Ex) COF long 2-1 fail, address 1 line open, Y b/d trouble, Maldischarge on screen.

Cautions of Key use after Finish
To change Mode, press down MODEL Up, Down simultaneously and turn power ON when the first power is ON (Ser->Epp, Epp->Ser : Epp(General Mode), Ser(Serial Communication Mode [Phone jack]) Always check the Mode when power is ON. When program is not downloaded, the program version doesnt display at the first Power On. Be sure to check the version of program before downloading. - If you didnt check the download could be duplicated Center LCD is lighted when power is ON. By pressing function key, green LED on upper right is ON and starts to operate. When its downloading green LED is flickering. When error occurs during operation red LED is ON.

Glossary & Definition of Defect
Glossary Non lighting Cell Defect Flashing Cell Defect Non-extinguishing Cell Defect High Intensity Cell Defect Condition Cell is always OFF Cell repeats On/Off Cell is always ON Cell is considerably brighter than others or different color appears Cause Particles or structural fault of cell Particles or structural fault of cell Particles or structural fault of cell Particles or structural fault of cell

3-2 Image Fault

Glossary Condition Cause The difference of brightness in the same gradation between lines with heavy load and lines with light load according to pictures. The layer is seen by skipping over neighboring gradation for White Balance & compensation with digital.

Quantizing Noise

Several luminance layer is seen in gradations of dark to bright. Especially a luminance layer of contour form is seen on human faces.

Glossary Condition Cause

Contour Noise
Contour noise appears as several false contours of objects on moving image due to the time difference of gradation.
PDP is a device displaying color by dividing seconds, so viewers sight follows image of video picture. Contour noise is having a false contour by the shade of the previous picture being added to the shade of current picture

Image Retention

The afterimage of the previous image continues after signal input and removal, which disappears in minutes. The previous afterimage is seen when changing a certain pattern to different patterns after displaying for a long time. Many unstable cells in gradation pattern are ON/OFF.
Memory Effect which is specific characteristic of AC PDP.

Image Sticking

Degradation of phosphor in fixed pattern which is displayed for hours.

Mis-writing

Unstable gradation signal when driving.
Cells which supposed to be Off repeat On/Off and are spread irregularly Incomplete removal of wall charge, space charge in Reset period Unequal condition of cell discharge by the uneven structure of panel Shift of Priming Charge by the structural fault of unit cells
Flashing Type Maldischar ge Luminesce nt Spot Type
Cells repeat On/Off in abnormal bright color and are spread irregularly (mostly in White, Gray Pattern) Cell that supposed to be Off flashes unnecessarily on certain places and tends to spread over time.

Crosstalk

Shift of Priming Charge by the structural fault of unit cells Polluted Cell
Colors in some part are different with normal part
Pollution of PCB while manufacturing

Over-discharge

Over-discharge in some part, which looks like stained spots especially in single or white pattern.
Pollution or unequal structure in some part on panel
Glossary Condition No lighting of vertical lines which supposed to be ON Vertical lines which supposed to be Off are lit up No lighting of horizontal lines which supposed to be On Cause Address electrode Open Fault on X-Board, Control-Board, compressed part of FPC Fault on X-Board, Control-Board, compressed part of FPC Sustain(Z), Scan(Y) electrode Open, Dielectric breakdown Fault on Z, Y-Board, Control-Board, compressed part of FPC Sustain(Z), Scan(Y) electrode Short Fault on Z, Y-Board, Control-Board, compressed part of FPC Electrode(Z, Y) breaking by high heat generated at dielectric breakdown by the fault(bubble, particle) inside of upper dielectric layer
