Operation Description on SMPS1. Overview
SMPS used in PDP 42" developed into the compact-sized with high efficiency.
The asymmetrical half bridge and the flyback converter are applied into all output. To comply with the
harmonic restrictions, it takes the power factor improvementcircuit, which converts AC into the high DC
and uses as the input of another converter controller.
2. Input controller
SMPS works in whole section of AC 90~264V. It is possible to start in the AC 90 and can restart with new
input voltage, even in interruption of electric power. STD_5V comes out when AC is impressed
3. Output Controller
Given SMPS have 15 output voltages. The following shows the specification of output voltage and output
current in case of their successive drive.

3-1. Overvoltage protection
It has circuit to maintain normal voltage, additionally with circuit for sensing overvoltage, so it means any
overvoltage does not give impacts on other output controller. SMPS prevents overvoltage in the latch mode.
VS(85V) works protection function more than 100V, over 94V for VA(75V), over 8.2V for D6V,
over 4.7V for D3.3V
Operation Description on SMPS 3-2. Short circuit and overvoltage protection
It forms definition that in the short circuit of output controller the output impedance is lower than 300mohm.
If the VS output have a short circuit in case of given SMPS, SMPS stops its working.
Even in the case of short circuit between main output and STD_5V, SMPS does not break down.
When the short circuit is removed, it restarts.
4. Detail Description
① AC-DC Converter
It converts AC into DC by using the power factor improvementcircuit. This converter was designated to
control the high frequency noise, with the function to improve the power factor. This part becomes input
controller of another constant-voltage.

Operation Description on SMPS ② Auxiliary Power
It is the part to supply power of mycom for remote control. When the power is on, it will work,
which means that MICOM is on standby.
This output part is stand_by voltage. When the power-on signal from remote control impress,
it works main power panel of SMPS via stand_by voltage.
③ Configuration of VS output
Major part of PDF SMPS outputs 85V 5A. It takes asymmetrical half bridge converter and connects
2 converters with 85V output in parallel, which increases efficiency than one 85V converter,
on the other hand, decreases its size.

2-2. 2-2. Operation Explanation of Driving CircuitOperation Explanation of Driving Circuit1. Overview of Driver Circuit
1) Definition of Driver Circuit
The driver circuit division drives the panel with the proper wave form (high voltage pulse) to develop image on
the outside terminal division (X electrode group, Y electrode group, Address electrode).
High voltage switching pulse is made by MOSFET combination.
2) Working Principle of Driver Circuit
To develop image on the PDP, the voltage should be impressed into the X, Y and ADDRESS electrodes
(which are component of each pictorial element) under the proper conditions. The driver wave form which is
currently applied to is ADS (Address & Display Separate: Driving method to work by dividing address and
constant-current section ) Based on this method, the discharge to be done in the pictorial element of PDP
can be divided into 3 types as follows.
● Address Discharge: to form the wall voltage within pictorial element by providing lighting pictorial
element with information(impressing data voltage)
: It is the discharge produced by difference between the positive electric potential of address electrode
(normally, Va impressed voltage of 70~75V +Positive Wall charge) and
negative electric potential of Y electrode
(GND level impression+ Negative Wall charge).
Operation Description on Driving Board
● Constant-current Discharge: It is the display section to form discharge voluntarily with the help of
wall voltage formed by address discharge. (It makes optical power to create image)
: It is the Self Sustaining Discharge made by combining the electric potential of coherent pulse, normally
160-170Volt, which alternates the X electrode with Y electrode in the sustain section, with the wall voltage
according to the pictorial element condition changed by if the former discharge exists or not. That is to say,
it works according to Memory characteristic (it means that former working condition defines the
current condition) as the basic feature of AC PDP.
If the wall voltage formerly exists in the pictorial element(i.e., the pictorial element is on), the discharge makes
forms again because the voltage higher than one of the discharging starting time is impressed by combination
of the wall voltage and of the next impressed constant-current.
While if the wall voltage does not exist in the pictorial element (i.e., the pictorial element is off), the discharge
does not form because the voltage could not reach to the level of the discharging starting time, only with
constant-current.
Operation Description on Driving Board ● Erasing discharge: To selectively perform the address discharge for respective pixel, pixels of all
panels must be on same conditions (same wall charge state and space charge state).
Therefore the erasing discharge zone is important factor to obtain driving margins.
There are various methods such as application of log waveform but the wall voltage control method
by the Ramp Waveform is now widely applied.
: The purpose of intialization (Erasing) discharge is to make wall voltage within the the whole of Pixels.
In other words, the erasing discharge must make difference between wall voltages uniform depending on
whether or not the sustain discharge exists in the previous state. Namely it must remove the wall voltage
formed by the sustain discharge and supply ions or elements by causing discharge for removing the wall
voltage. In the other words, To remove the wall voltage, limit the time when polarity of the wall voltage is
reversely charged by causing discharge or prevent polarity form being reversely charged by supplying
appropriate quantity of ions or elements through forming weak discharge [low voltage of erasing].
There are two types of the weak discharge [low voltage]as known so far. 1) Log Waveform adopted by
the F-company 2) Weak erasing discharge by the Ramp Waveform largely adopted by Matsushita
company, etc. Outside applied voltage is adjusted depending on difference of wall voltage within Pixel,
since discharge is formed when the sumof the existing wall voltage remained and the voltage on a
rising waveform exceed the driving beginning voltage, by slowly applying the
rising slope of the erased waveform for these two methods. In addition,
weak discharge is formed since the strength of applied voltage is small.

Explanation of Function per Pulse
● Y Rising Ramp Pulse
Outside voltage of about 390V~400V is applied to the Y electrode in the Y Rising Ramp zone, and weak
discharge begins if respective gap voltage equals to the discharge beginning voltage.
Negative Wall charges accumulate on the Y electrode and the Positive Wall charges on the X electrode in
the whole while weak discharge is maintained.
● Y Falling Ramp Pulse
Most of Negative Wall charges accumulated on the Y electrode by the X bias of about 200V are used to
remove Positive Wall charges in the Y Falling Ramp zone, and most of Positive charges accumulated on
the (0V) Rising Ramp zone toward the address electrode are maintained, having distribution of wall
charges beneficial for the subsequent address discharge.
Explanation of Function per Pulse● Y Scan Pulse
Y scan pulse is called as injection pulse, and selects the Y electrode one by one (Line-at-a-time).
In this case, Vscan is called as Scan bias. For the electrode line with the Vscan voltage applied,
voltage of about 70 Volt (Vscan) is applied, and voltage of 0 Volt(GN0) is applied.
However, since Negative Wall charges accumulate on the Y electrode by the application of Ramp pulse
and Positive Wall charges accumulate on the address electrode, voltage of more than the discharge
beginning voltage is applied to the cell where address pulse(70V~75V) is allotted and thus address
discharge occurs. Address time of the PDP is very long since both scan pulse and data pulse must be
applied in line at a time.
● 1st Sustain Pulse
The Sustain Pulse always begins from the Y electrode, it is because Positive Wall charges are formed on
the Y electrode if address discharge occurs. The wall charges formed by the address discharge are less
than those for the sustain discharge, and thus the strength of the initial discharge is weak.
Sustain discharge usually become stable after 5~6 times of discharge depending on structure of electrode
and environment. Therefore, the initial long sustain pulse is intended to form the initial
discharge stable and form the wall charges much as possible as.
1. Y buffer - To check whether there is failure of the Y Main, firstly check normal operation of the Y buffer. - After separating both the Y Main and the Y buffer connector, - Check forward voltage drop of 0.4V ~ 0.5V by diode check between OUTL and OUTH. - In addition, resistance between both ends is also more than several kΩ.
