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.

4

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.

5

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.

6

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.

7

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.

10.2. Energy Recovery Drive Pulse Output

10.2.1. Plasma Panel Energy Loss

When The Sustain, Scan and Data drive pulses are supplied to the plasma panel a lot of energy was lost by resistance of the
electrodes lead and many of switching elements. Because plasma panel has the stray capacitance and this capacitance makes
high level inrush current during the charge and dischange.
This energy loss becomes high temperature from the plasma panel itself.

13.1. Schematic Diagram Notes

Important Safety Notice

Components identified by mark have special characteristics important for safety.
When replacing any of these components, use only manufacture's specified parts.

Notes:

1. Resistor
All resistors are cabon 1/4W resistor, unless marked as follows:
Unit of resistance is OHM [W] (K=1,000, M=1,000,000).

: Nonflammable : Metal Oxide
: Solid : Metal Film
: Wire Wound : Fuse:

2. Capacitor
All capacitors are ceramic 50V capacitor, unless marked as follows:
Unit of capacitance is mF, unless otherwise noted.

: Temperature Compensation : Electrolytic
: Polyester : Bipolar

M
m T

: Metalized Polyester : Dipped Tantalum
: Polypropylene : Z-Type

3. Coil
Unit of inductance is mF, unless otherwise noted.

4. Test Point

: Test Point position

5. Earth Symbol

: Chassis Earth (Cold) : Line Earth (Hot)

6. Voltage Measurement
Voltage is measured by a DC voltmeter.
Conditions of the measurement are the following:

Power Source ................................................... AC 220V-240V, 50/60Hz

Power Source ...................................................

Power Source ...................................................

Receiving Signal ............................................... Colour Bar signal (RF)

All customer's controls ...................................... Maximum positions

7. Number in red circle indicates waveform nember.
(See waveform pattern table.)

8. When arrow mark ( ) is found, connection is easily found from the direction of arrow

TH-50PHD3 / TH-50PHW3

Remarks:

1. The Power Circuit contains a circuit area which uses a separate power supply to isolate the
earth connection.
The circuit is defined by HOT and COLD indications in the schematic diagram. Take the
follwing precautions.
All circuits, except the Power Circuit, are cold.
Precautions

a. Do not touch the hot part or the hot and cold parts at the same time or you may

be shocked.

b. Do not short- circuit the hot and cold circuits or a fuse may blow and parts may

break.

c. Do not connect an instrument, such as an oscilloscope, to the hot and cold

circuits simultaneously or a fuse may blow.

Connect the earth of instruments to the earth connection of the circuit being

measured.

d. Make sure to disconnect the power plug before removing the chassis.

2. Following diodes are interchangeable.
