Principle of PDP light emission is the same as fluorescent lamp.

2 pieces of glass plates are placed with a small gap of 0.1mm, which isfilled with discharge gas, and one of the glass plate has a transparent

electrode. When 100 and several ten V of voltage is applied to the

electrodes, discharge starts and generates UV light. This UV light

reaches to the other glass plate on which phosphors (R,G,B) are pasted,

and the phosphors convert UV light to visible light.

PDP Driving

Characteristics


15/55

.SMPS(Switching Mode Power Supply)

: It is the supplier to provide voltage and current to work the drive voltage and panel in each board.

.X-MAIN BOARD

: It makes the drive wave form by switching FETs to Timing Controlle coming from logic-board and

supplies X electrode of panel with the drive wave form via connector.

.Y-MAIN BOARD

: It makes the drive wave form by switching FETs to Timing Controller coming from the logic-board

and provides Y electrode of panel with the drive wave form via Scan Driver IC on Y buffer board

in order.

.LOGIC MAIN BOARD

: It process image signal and performs buffering of the logic-main board (to create XY drive signal

and output) and the address driver output signal.

Then it supplies the output signal to the address driver IC(COF Module).

Function Description by board - 1

3. PDP Driving Characteristics


16/55

.LOGIC BUFFER(E,F,G) : It delivers the data signal and control signal to the COF.

.Y-BUFFER (Upper,Lower)

: It is the board to impress the scan waveform on the Y board and consist of 2 boards

(upper board and lower board).

8 Y-buffers are fixed at the scan driver (STV7617 of STC corp. : 64 or 65 Output).

.AC Noise Filter

: It has functions to remove noise(low frequency) coming from AC LINE and prevent surge.

It gives serious effects on the safety regulations (EMC, EMI) according to AC filter.

.COF (Chip on Flexible)

: It impress the Va pulse to the address electrode in the address section and forms the

address discharge by electric potential difference with scanning pulse to be dismissed

by the Y electrode. It is made in the form of COF and one COF consists of 4 Data Drive IC

(STV7610A :96 Output), otherwise single scan is made of 7 COF.

Special Management Items1) It is Cell-Defect if there are dark, bright,

flickering cells over 2 pointswithin

1.5cm in the boundary section.

2) Before vibration/dropping test, it should

be decided whether the module is good

/ badness first.

And after vibration/dropping test,

if Cell-Defect happens more than

preceding descriptions on Specification,

it is Cell-Defect module.
