WARNING
- The Module is controlled by high voltage about 350V. If you need to handle the Module during operation or
just after power-off, you must take proper precautions against electric shock and must not touch the drive
circuit portion and metallic part of Module within 5 minutes. The capacitors in the drive circuit portion remain
temporarily charged even after the power is turned off. After turning off the power, you must be sure to wait
at least one minute before touching the Module. If the remain voltage is strong enough, it could result in
electric shock.
- Do not use any other power supply voltage other than the voltage specified in this product specifications. If
you use power voltage deviated from the specifications, it could result in product failure.
- Do not operate or install under the deviated surroundings from the environmental specification set for the
below; in moisture, rain or near water-for example, bath tub, laundry tub, kitchen sink; in a wet basement; or
near a swimming pool; and also near fire or heater - for example, near or over radiator or heat resistor; or
where it is exposed to direct sunlight; or somewhere like that. If you use the Module in places mentioned
above, it could result in electric shock, fire hazard or product failure.
- If any foreign objects (e.g. water, liquid and metallic chip or dust) entered the Module, the power supply
voltage to the Module must be turned off immediately. Also, never push objects of any kind into the Module
as they may touch dangerous voltage point or make short circuits that could result in fire hazard or electric
shock.
- If smoke, offensive smell or unusual noise should come from the Module, the power supply voltage to the
Module must be turned off immediately. Also, when the screen fails to display any picture after the power-on
or during operation, the power supply must be turned off immediately. Do not continue to operate the
Module under these conditions.
- Do not disconnect or connect the Module's connector while the power supply is on, or immediately after
power off. Because the Module is operated by high voltage, and the capacitors in drive circuit remain
temporarily charged even after the power is turned off. If you need to disconnect or reconnect it, you have to
wait at least one minute after power off.
- Do not disconnect or connect the power connector by a wet hand. The voltage of the product may be strong
enough to cause an electric shock.
- Do not damage the power cable of the Module, also do not modify it.
- When the power cable or connector is damaged or frayed, do not use it.
- When the power connector is covered with dust, please wipe it out with a dry cloth before power on.

NOTICE
- To prevent defect or failure, please check the cable connections and power-supply condition before
power-on.
- The Module is controlled by high voltage. Not only during operation but also immediately after power-off, do
not disconnect or reconnect the Module's connector because it may result in failure. If you need to
disconnect or reconnect, you have to wait at least one minute after power-off.
- The Module is equipped with various protection circuits that automatically stop the Module operation, if an
interface signal or the power voltage becomes abnormal during operation. If the Module stops suddenly
during operation, please check the conditions of input signal or power source before restarting.
- For the protection of the circuit, if an abnormal situation is occurred, the high output voltage will be shut
down by (watching) the internal input voltage (Vs/ Va/ Vcc). In this case, the Module power resetting is
necessary to recover. There are also fuses in the Vs and Va power supply system to prevent smoking and
firing by the excessive current. The protecting function of the address driver of keeping a supervisory
device for the internal current is provided in the Va power supply system. Therefore, the number of
sub-frames decreases to a proper value when the Ia current exceeds a constant value occasionally.
- If an abnormal situation such as disconnecting of the input connector occurs, this Module will be on stand-by,
which the supply of high output voltage is stopped even if an external power is being supplied. If a normal
signal is inputted after this, normal operation state, operations can be restarted again by re-inputting a
normal signal. However, it is necessary to rest the Module power when tVH and/or tHV are less than the
minimum value provided in the specification
- To ensure reliable operation of the Module and to protect it from overheating, do not wrap or cover it with a
cloth or like a sheet during power-on period. Also, do not place the Module in a confined space or any other
places of poor ventilation.
- If you continue to watch the naked screen (without filter glass) for a long time, your eyes could be fatigued.
We recommend you rest your eyes occasionally. However, according to the information currently available,
watching PDP module for a long time does not cause a direct harm to your eyes.
- The screen is controlled with the display-data signals and synchronized signals. If noise interferes with those
signals, the screen could become unstable and, in some case, would cause a failure. Do not place any
equipment that generates excessive EMI/RFI noise near the interface cable of the Module, and keep the
cables as short as possible.
- Be careful not to break the glass panel when you handle the Module. Also, when handling the Module, you
must wear gloves or other hand protection to prevent injuries that can occur in case when the glass panel is
broken.
- The glass panel section and drive circuit section of the Module are closely connected and they function as a
pair. If the Module is arbitrarily recombined, restructured, or disassembled, SDI will not be responsible for
the function, quality, or operational integrity of the modified Module. Do not recombine, restructure, or
disassemble it. (Only, the Module for A/S is allowed to be recombined, restructured, or disassembled.)
- To avoid a possible electric shock, you must make sure that the power supply voltage of Module is turned
off before cleaning. To clean the module’s glass panel, apply water or a natural detergent to a piece of
soft cloth or gauze, and wring the cloth tightly before wiping the screen. Make sure that no water comes in
contact with the connecting terminals on the side of the glass panel. Do not use chemical solvents, such
as paint thinner or benzene, to clean the glass panel.

- The drive circuit section of Module uses C-MOS integrated circuits that must be protected from static
electricity. Therefore, when transporting or delivering the Module, be sure to put the Module in an antistatic
bag. When handling the Module, take adequate grounding precautions to prevent static electricity.
- When delivering or transporting the Module, you must take special precautions because excessive vibration
or shock should not be applied to it. If the Module is dropped, or (if) excessive vibration/shock is applied,
the glass panel of the Module may be broken and the drive circuit may be damaged. The packing for
delivering or transporting should be made with strict instructions.
- The information and schematics shown in this specification are just examples of display applications; it does
not mean that they must be applied to your device for the actual use. SAMSUNG SDI does not take any
responsibility for the infringement of patent or any other intellectual rights arising from the use of the
information or schematics in the document.
- If any part or technology of the product described in this specification become subject to restrictions on
export or any related laws or regulations, a prior permission is required before exporting.
- The PDP module uses semiconductor devices. Since semiconductors are very sensitive to static electricity,
the following requirements should be conformed during delivering, transferring and handling the PDP
module: Remove the static electricity on your body by wearing the earth-ring which must be connected to
the ground through high resistor (about 1M Ohm). It is recommended to wear the conductive clothes and
shoes, use conductive floor mats, and take other measures to minimize the static electricity. All the
equipments and tools must be connected to the ground and protected from static electricity. When you
deliver or transfer the PDP module, always use anti-static bag.
- If any device that can generate the high-voltage is located nearby the PDP module, it could cause an
abnormal operation. In such a case, you should take a countermeasure to prevent against static electricity
and discharges.
- If the PDP module is exposed to corrosive gases or contacted to oil, it could cause chemical reactions and
give unfavorable effects on the devices. If you intend to use the PDP module under such conditions, you
must consider the ways to avoid exposure or to protect the PDP module before using it.
- The PDP module is not designed to endure radiation or cosmic radiation. Users must install the proper
shielding.
- The PDP module uses thermo-plastic devices. Since these devices are easy to be damaged, do not use the
PDP module nearby inflammable substances. If they are burnt, poisonous gas will be emitted.
- To ensure the normal operation of the PDP module, the recommended operating range should be required.
The electrical properties of the PDP module are guaranteed only when it is used within the recommended
operating range. The PDP module must be used within the range at all time. If you use it out of the range, it
could give adverse effects on its reliability or cause defects.
- Flexible cables connect electrodes on the panel glass and PCBs. Thus, do not apply too much stress such
as shock, vibration, pressure, or bending, to the surface of panel glass, PCBs and flexible cables.
- If there is no special notice, the contents of this specification describe the product with the initial parameters
after shipment.

- Even if the panel glass is cleaned before shipping, there is a possibility of particle remained on the panel. In
this case, remove it prior to the usage. When you clean the surface of the panel glass, use a piece of soft
cloth with detergent to wipe off. Do not use any chemical substances such as acid, alkali or organic
detergent.
- The Module is composed of various kinds of materials such as glass, metals and plastics. A qualified service
technician is required for the disposal of the Module.
CAUTION
- Do not set the Module on an unstable, vibrating or inclined place. The Module may fall or collapse and it may
cause a serious injury to a person, and/or damage to the product.
- If you need to remove the Module to another place, you must turn off the power supply and detach the
interface cable and power cable from the Module beforehand, and watch your steps not to step on the
cables during the operation. If the cables are damaged during the transport, it may result in fire hazard or
electric shock. Also if the Module is dropped or fallen, it may cause a serious injury to a person and /or
damage to the product.
- When you draw or insert the module's cable, you must turn off the power supply and do it (with) holding the
connector. If you forcibly draw the cable, the electric wire in the cable can be exposed or broken. It may
result in fire hazard or electric shock.
- When you carry the Module, it should be done with at least two workers in order to avoid any unexpected
accidents.
- Be careful not to touch the panel glass surface while the PDP module is operating because there is a
possibility of getting a burn injury due to its very high temperature.
- The Module has a glass-plate. If the Module is inflicted with excessive stress – for example; shock, vibration,
bending or heat-shock, the glass plate could be broken. It may result in a personal injury. Also, do not press
or strike the glass surface.
- If the glass panel was broken, do not touch it with bare hand. It may result in a cut injury.
- Do not place any object on the glass panel. It may be the cause of the scratch or break of the glass panel.
- Do not place any object on the Module. It may result in a personal injury due to fall or drop.
- PDP is a product, which generates heat during operation. Therefore, do not use the materials which make
corrode the PDP module by the chemical reaction that takes place in high temperature and humidity
conditions.
- Exposing to corrosive gases or contact with the materials, which may cause corrosions, could lead to
chemical reactions that will adversely affect on the device. If you were to use the PDP in such conditions,
consider ways to avoid such exposure or to protect the PDP module.
