5. PRECAUTIONS FOR USING LCD MODULES
Installing LCD Modules
The hole in the printed circuit board is used to fix LCM as shown in the picture below. Attend to the following items when
installing the LCM.
1) Cover the surface with a transparent protective plate to protect the polarizer and LC cell.
2) When assembling the LCM into other equipment, the spacer to the bit between the LCM and the fitting plate
should have enough height to avoid causing stress to the module surface, refer to the individual specifications for
measurements. The measurement tolerance should be
0.1mm.
Precaution for Handing LCD Modules
Since LCM has been assembled and adjusted with a high degree of precision, avoid applying excessive shocks to the module or
making any alterations or modifications to it.
1) Cover the surface with a transparent protective plate to protect the polarizer and LC cell.
2) Do not alter, modify or change the shape of the tab on the metal frame.
3) Do not make extra holes on the printed circuit board, modify its shape or change the positions of components to
be attached.
4) Do not damage or modify the pattern writing on the printed circuit board.
5) Absolutely do not modify the zebra rubber strip (conductive rubber) or heat seal connector.
6) Except for soldering the interface, do not make any alterations or modifications with a soldering iron.
7) Do not drop, bend or twist LCM.
Electro-Static Discharge Control
Since this module uses a CMOS LSI, the same careful attention should be paid to electrostatic discharge as for an ordinary
CMOS IC.
1) Make certain that you are grounded when handing LCM.
2) Before remove LCM from its packing case or incorporating it into a set, be sure the module and your body have
the same electric potential.
3) When soldering the terminal of LCM, make certain the AC power source for the soldering iron does not leak.
4) When using an electric screwdriver to attach LCM, the screwdriver should be of ground potentiality to minimize
as much as possible any transmission of electromagnetic waves produced sparks coming from the commutator of
the motor.
5) As far as possible make the electric potential of your work clothes and that of the work bench the ground
potential.
6) To reduce the generation of static electricity be careful that the air in the work is not too dried. A relative
humidity of 50%-60% is recommended.
Precaution for soldering to the LCM
1) Observe the following when soldering lead wire, connector cable and etc. to the LCM.
a) Soldering iron temperature : 280
C 10C.
b) Soldering time : 3-4 sec.
2) Solder : eutectic solder.
SPECIFICATIONS FOR LIQUID CRYSTAL DISPLAY MODULE
MODEL NO: 16235
PACIFIC DISPLAY DEVICES
07.01.2003

3) If soldering flux is used, be sure to remove any remaining flux after finishing to soldering operation. (This does
not apply in the case of a non-halogen type of flux.) It is recommended that you protect the LCD surface with a
cover during soldering to prevent any damage due to flux spatters.
4) When soldering the electroluminescent panel and PC board, the panel and board should not be detached more
than three times. This maximum number is determined by the temperature and time conditions mentioned above,
though there may be some variance depending on the temperature of the soldering iron.
5) When remove the electroluminescent panel from the PC board, be sure the solder has completely melted, the
soldered pad on the PC board could be damaged.
Precautions for Operation
1) Viewing angle varies with the change of liquid crystal driving voltage (VO). Adjust VO to show the best contrast.
2) Driving the LCD in the voltage above the limit shortens its life.
3) Response time is greatly delayed at temperature below the operating temperature range. However, this does not
mean the LCD will be out of the order. It will recover when it returns to the specified temperature range.
4) If the display area is pushed hard during operation, the display will become abnormal. However, it will return to
normal if it is turned off and then back on.
5) Condensation on terminals can cause an electrochemical reaction disrupting the terminal circuit. Therefore, it
must be used under the relative condition of 40
C , 50% RH.
6) When turning the power on, input each signal after the positive/negative voltage becomes stable.
Safety
If the LCD panel breaks, be careful not to get the liquid crystal in your mouth. If the liquid crystal touches your skin
or clothes, wash it off immediately using soap and plenty of water.
Handling
The display panel is made of glass. Do not subject it to a mechanical shock by dropping it or impact.
If the display panel is damaged and the liquid crystal substance leaks out, be sure not to get any in your mouth. If the
substance contacts your skin or clothes, wash it off using soap and water.
Do not apply excessive force to the display surface or the adjoining areas since this may cause the color tone to vary.
The polarizer covering the display surface of the LCD module is soft and easily scratched. Handle this polarizer
carefully.
If the display surface becomes contaminated, breathe on the surface and gently wipe it with a soft dry cloth. If it is
heavily contaminated, moisten cloth with one of the following solvents :
o Isopropyl alcohol
o Ethyl alcohol
Solvents other than those above-mentioned may damage the polarizer. Especially, do not use the following.
o Water
o Ketone
o Aromatic solvents
Exercise care to minimize corrosion of the electrode. Corrosion of the electrodes is accelerated by water droplets,
moisture condensation or a current flow in a high-humidity environment.
Install the LCD Module by using the mounting holes. When mounting the LCD module make sure it is free of
twisting, warping and distortion. In particular, do not forcibly pull or bend the I
/O cable or the backlight cable.
Do not attempt to disassemble or process the LCD module.
NC terminal should be open. Do not connect anything.
If the logic circuit power is off, do not apply the input signals.
SPECIFICATIONS FOR LIQUID CRYSTAL DISPLAY MODULE
MODEL NO: 16235

17
To prevent destruction of the elements by static electricity, be careful to maintain an optimum work environment.
o Be sure to ground the body when handling the LCD modules.
o Tools required for assembling, such as soldering irons, must be properly grounded.
o To reduce the amount of static electricity generated, do not conduct assembling and other work under dry
conditions.
o The LCD module is coated with a film to protect the display surface. Exercise care when peeling off this
protective film since static electricity may be generated.
Storage
When storing the LCD modules, avoid exposure to direct sunlight or to the light of fluorescent lamps
Store the module in a dark place where the temperature is 25
o
C 10
o
C and the humidity below 65% RH.
Do not store the module near organic solvents or corrosive gases.
Do not crush, shake, or jolt the module (including accessories).
Cleaning
Do not wipe the polarizing plate with a dry cloth, as it may scratch the surface.
Wipe the module gently with soft cloth soaked with a petroleum benzene.
Do not use ketonic solvents (ketone and acetone) or aromatic solvents (toluene and xylene), as they may damage the
polarizing plate.
Others:
Liquid crystals solidify under low temperature (below the storage temperature range) leading to defective orientation
or the generation of air bubbles (black or white). Air bubbles may also be generated if the module is subject to a low
temperature.
If the LCD modules have been operating for a long time showing the same display patterns, the display patterns may
remain on the screen as ghost images and a slight contrast irregularity may also appear. A normal operating status can
be regained by suspending use for some time. It should be noted that this phenomenon does not adversely affect
performance reliability.
To minimize the performance degradation of the LCD modules resulting from destruction caused by static electricity
etc., exercise care to avoid holding the following sections when handling the modules.
-
Exposed area of the printed circuit board.
-
Terminal electrode sections.
