TH-50PHD3 / TH-50PHW3

1 Plasma Display Technology

1.1. Plasma display panel

Fig. A

Panasonic 42 inch wide plasma display panel is develope for large screen multimedia display with space saving.

The plasma display panel use AC type Sub-field drive system with Dual scanning system.

This panel have also Panasonic original Asymmetric cell and Plasma AI technology.

Fig. A Is the CRT and Plasma Display Panel(PDP) comparison chart.

1.3. Rear Glass Structure

Fig. C

On the rear glass the data electrode is mounted.

The dielectric is coated on the rear glass.

Red, Green and Blue colour phosphors are formed on the data electrode with the ribs. However to improve colour reproduction and brightness, each colour phosphors are formed different width This is called " Asymmetrical cell " as Panasonic original technology.

1.4. Front Glass Structure

1.2. Plasma display panel structure

Fig. B

Plasma display panel structure

Panasonic Plasma display panel is consist of front glass, rear glass and Aluminum base.

The front glass has each 768 lines scan and sustain transparence electrodes.

The rear glass has 4098 (1366 x 3 ) data electrodes on the inner surface. These electrodes are connected to the data drive circuit boards directory.

Fig. D

On the front glass scan and sustain transparent electrodes are mounted in pair.

The dielectrics is coated on the front grass.

MgO over coat is also applied on the dielectrics.

The front and rear glasses are piled and sealed . And low presser gas are charged between two glasses.

1.5. Pixel Structure

Fig. E

50 inch plasma display panel has 1,049,088 pixels.

Each pixels structure is shown fig. E.

1.6. Sub Field Drive system

TH-50PHD3 / TH-50PHW3

1.7. Initialization

Fig. G

To clear any remaining electric charge into the pixel, trapezoid voltage is applied between the scan and sustain electrodes.

Plasma discharge is started but the discharge become small gradually.

Then any electric charge is cleared.

1.8. Write

Fig. F

Brightness control of plasma display panel is carried out by plasma discharge time change. To control each pixelís brightness Sub-field drive system is used.

A sub-field is consist of Initialize, Write and sustain operation.

Fig. H

Data Pulse which is positive polarity is input to data electrode and Scan pulse which is negative polarity is input to scan electrode simultaneously.

That means sum of data and scan pulses voltage is applied between two electrodes as discharge start voltage.

Discharge is started into the pixel and gas is ionized.

During discharging Ion is charged on the scan electrode side and electron is charged on data electrode side.

TH-50PHD3 / TH-50PHW3

1.9. Wall Voltage

1.11. Sustain Step 2

Fig. I

When input pulses are stopped, Ions and Electrons which are charged on the dielectric around the electrodes are remained.

This charge is called Wall Voltage (Pilot voltage).

This operation is called Write .

1.10. Sustain Step 1

Fig. J

Negative polarityís Sustain pulse is input between sustain and scan electrodes and voltage potential between two electrodes becomes sum of Sustain pulse and wall voltage.

Then discharge start.

Fig. K

When sustain pulse is stopped, Ions and Electrons are remained again as Wall voltage. However polarity of wall voltage is reversed.

1.12. Sustain Step 3

Fig. L

Positive polarity´s Sustain pulse is input between sustain and scan electrodes and discharge start again.

1.13. Sustain Step 4

TH-50PHD3 / TH-50PHW3

1.15. Repeat Step 1 to Step 5

Fig. M

When sustain pulse is stopped, Ions and Electrons are remained again as Wall voltage. However polarity of wall voltage is reversed.

1.14. Sustain Step 5

Fig. N

Ions and Electrons which is generated by 2nd sustain discharge are charged on the pixel wall(dielectric) around the electrodes.

Fig. O

To keep discharge continuously step 1 to 5 operation will be repeated.

As the result sustain pulse is alternated. Therefore we call this drive system AC Drive type.

If sustain operation is repeated longer, brightness level of the pixel is increased. Therefore depend on sustain discharge time brightness of pixel is controlled.

1.16. Sub-Field drive

Fig. P

Sub-Field drive is PDP unique system.

While one TV field period, 8 bits digital video signal component is reproduced by 8 sub-fields operation.

Each Sub-Field´s address period are all same.(Consist of one initialization and 768 scanning operation)

But Sustain period of each Sub-Field are different.1st SubField(SF) reproduce only 1 step brightness.

2nd SF reproduce 2 steps brightness.

Each sub-field´s sustain period are increased gradually.

However total 256 brightness difference can be reproduced on the screen.

TH-50PHD3 / TH-50PHW3

1.17. Dual Scan

1.19. Real Black drive

Fig. Q

The sustain period of sub-field drive system. Therefore brightness peak is limited. Because 768 horizontal lines scanning is carried out during address period.

Dual scan system can reduce scanning time from 768 to 384 in the address period.

Then spaced time by dual scanning can be used for sustain operation.

As the result Brightness peak level can be increased.

1.18. Plasma AI (Adaptive brightness Intensifier)

Fig. S

For standard sub field drive, initialization discharge is done at each sub field. So that during one TV field period same sub field numbers of discharges are done even black signal was displayed.

Therefore there are small emission at the black area.

Panasonic Real Black drive system improve black reproduction.

Initialization discharge is done at first sub field only.

Remaining sub field are not required discharge because Real Black drive circuit applies initialization electric field remainder pulse.

Fig. R

Panasonic plasma AI control sub-field drive operation which is called Multi-Sprit Sub-Field drive control system.

Depend on the picture contents ( APL : Average Picture Level ) sustain time format of each sub-field are also rearranged from binary format to linear cording sustain time. (Linear coding subfield)

Plasma AI select the best display condition for Plasma display panel to display natural and crisp picture.
