Plasma Display Technology
Plasma display panel
FIg. A
Panasonic 37/42 inch wide plasma display panel is devel-
oped for large screen multimedia display with space saving.
The plasma display panel use AC type Sub-field drive sys-
tem 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) compari-
son chart.
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 480 lines scan and sustain trans-
parence electrodes.
The rear glass has 2556 (852 x 3 ) data electrodes on the
inner surface. These electrodes are connected to the data
drive circuit boards directly.
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 color phosphors are formed on the
data electrode with the ribs. However to improve color repro-
duction and brightness, each color phosphors are formed dif-
ferent width This is called " Asymmetrical cell " as Panasonic
original technology.
Front Glass Structure
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.

Pixel Structure
Fig. E
37/42 inch plasma display panel has 1,226,880 pixels.
Each pixels structure is shown fig. E.
Sub Field Drive system
Fig. F
Brightness control of plasma display panel is carried out by
plasma discharge time change. To control each pixel’s bright-
ness Sub-field drive system is used.
A sub-field is consist of Initialize, Write and sustain opera-
tion.
Initialization
Fig. G
To clear any remaining electric charge into the pixel, trape-
zoid voltage is applied between the scan and sustain elec-
trodes.
Plasma discharge is started but the discharge become small
gradually.
Then any electric charge is cleared.
Write
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.

Wall Voltage
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 .
Sustain Step 1
Fig. J
Negative polarity’s Sustain pulse is input between sustain
and scan electrodes and voltage potential between two elec-
trodes becomes sum of Sustain pulse and wall voltage.
Then discharge start.
Sustain Step 2
Fig. K
When sustain pulse is stopped, Ions and Electrons are
remained again as Wall voltage. However polarity of wall volt-
age is reversed.
Sustain Step 3
Fig. L
Positive polarity’s Sustain pulse is input between sustain and
scan electrodes and discharge start again.

Sustain Step 4
Fig. M
When sustain pulse is stopped, Ions and Electrons are
remained again as Wall voltage. However polarity of wall volt-
age is reversed.
Sustain Step 5
Fig. N
Ions and Electrons which is generated by 2nd sustain dis-
charge are charged on the pixel wall (dielectric) around the
electrodes.
Repeat Step 1 to Step 5
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 dis-
charge time brightness of pixel is controlled.
Sub-Field drive
Fig. P
Sub-Field drive is PDP unique system.
While one TV field period, 8 bits digital video signal compo-
nent is reproduced by 8 sub-fields operation.
Each Sub-Field’s address period are all same.(Consist of
one initialization and 480 scanning operation.)
But Sustain period of each Sub-Field are different.
1st Sub-Field (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.

Dual Scan
Fig. Q
The sustain period of sub-field drive system. Therefore
brightness peak is limited. Because 480 horizontal lines
scanning is carried out during address period.
Dual scan system can reduce scanning time from 480 to 240
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.
Plasma AI (Adaptive brightness Intensi-

Panasonic plasma AI control sub-field drive operation which
is called Multi-Sprit Sub-Field drive control system is used.
Depend on the picture contents ( APL : Average Picture
Level ) number of sub-field are changed from 10 to 12. (Vari-
able Sub-field)
Sustain time format of each sub-field are also rearranged
from binary format to linear cording sustain time. (Linear cod-
ing sub-field)
Plasma AI select the best display condition for Plasma dis-
