14. NOTE
14.1 FOR SAFETY
LCD module is generally designed with precise parts to achieve light weighted thin mechanical
dimensions.
In using our Modules, make certain that you fully understand and put into practice the warnings
and safely precautions detailed in engineering information.
Refer to individual specifications and technical data for more detailed technical information.
1ˊ SPECIAL PURPOSES
A) JCT'S Standard LCD Modules have not been customized for operation in extreme
environments or for use in applications where performance failures could be life-threatening or
otherwise catastrophic.
B) Since JCT’S Standard LCD Modules have not been designed for operation in extreme
environments, they must never be used in devices that will be exposed to abnormally high
levels of vibration or shock which exceed JCT Corp. published specification limits.
C) In addition, since JCT Standard LCD Modules have not been designed for use in applications
where performance failures could be life-threatening or catastrophic, they must never be
installed in aircraft navigation control systems ǃcritical industrial process control systems(e.g.
those involved in the production of nuclear energy) or in critical medical device or patient
lift-support systems.
2ˊ DISASSEMBLING OR MODIFICATION
DO NOT DISASSEMBLE OR MODIFY the module. It may damage sensitive parts inside LCD
module, and may cause scratches or dust on the display.
JCT Corp. doses not warrant the module, if customer disassembled or modified it.
3ˊ BREAKAGE OF LCD PANEL
DO NOT INGEST liquid crystal material, DO NOT INHALE the material with skin, if LCD panel is
broken and liquid crystal material spills out.
If liquid crystal material comes into mouth or eyes, rinse mouth or eyes out with water immediately.
If this material contact with skin or cloth, wash it off immediately with alcohol and rinse thoroughly
with water.
4ˊ GLASS OF LCD PANEL
BE CAREFUL WITH CHIPS OF GLASS THAT MAY CAUSE INJURING FINGERS OR SKIN, when
the glass is broken.
5ˊ ELECTRIC SHOCK
DISCONNECT POWER SUPPLY before handling LCD module.
DO NOT TOUCH the parts inside LCD module and the fluorescent lamp’s connector or cables in
order to prevent electric shock, because high voltage is supplied to these parts from the inverter unit
while power supply is turned on.
6ˊ ABSOLUTE MAXIMUM RATINGS AND POWER PROTECTION CIRCUIT
DO NOT EXCEED the absolute maximum rating values under the worst probable conditions caused
by the supply voltage variation, input voltage variation, variation in parts’ constants, environmental
temperature, etc, otherwise LCD module may be damaged.
Employ protection circuit for power supply, whenever the specification or TD specifies it.
Suitable protection circuit should be applied each system design.
7ˊ DISPOSAL
When dispose LCD module, obey to the applicable environmental regulations

14.2 For Designing the System
(1) LCD module should be assembled to the system by using all mounting holes specified in this
specification and with the specified screws.
(2) DO NOT GIVE high voltage to “Low Voltage” side of the FL.
For example, DO NOT USE a flowing inverter which gives high voltage to “Low Voltage” side. That’s
because it has a possibility to burn or smoke around the FL.
(3) Make sure to connect correctly high-voltage wire and low-voltage wire between FL tube and inverter
unit.
(4) Input FL starting voltage (V
If it were less than one second, it may cause unstable operation of FL.
Please adjust inverter circuit parameters, such as capacitor, resistor, to assure the display quality is
maintained.
There is a possibility that flicker is observed by the interference of LCD operating signal timing and
(5) In case of severe environmental condition like outdoor usage, a proper transparent protective cover
(lens) over LCD module is recommended to apply in order to prevent scratches, and invasion of
dust, water, etc., from the system’s window onto LCD module.
Ultra-violet ray cut filter is recommended to apply onto LCD module for outdoor operation. Strong
ultra-violet ray may cause damage the panel.
(6) Design the system not to display same pattern for a long time in order to prevent image sticking on
the panel. Note that incorrect sequence of power supplies and input signals may cause the sticking
on the panels, too.

) should not be less than one second.

14.3 For Installation in Assembly
(1) The C-MOS LSI used in LCD module is very sensitive to ESD (Electro-static Discharge).
Ambient humidity of working area is recommended to be higher than 50%RH.
Person handling LCD modules should be ground with wrist band. Tools like soldering iron and screw
driver, and working benches should be grounded.
The grounding should be done through a resister of 0.5-1 Mohms in order to prevent spark of ESD.
(2) Reduce dust level in working area. Especially the level of metal particle should be decreased. Use
finger stalls or soft and dust-free gloves in order to keep clean appearance of LCD module when
handle for incoming inspection and assembly
(3) When remove protection film from LCD panel, peer off the film slowly (more than three second from
the edge of the panel to minimize ESD, using a soft-pointed tweezers covered by Teflon or adherent
tape.
(4) When LCD panel becomes dirty, wipe of the panel surface softly with absorbent cotton or another
soft cloth.
If necessary, breathe upon the panel surface and then wipe off immediately and softly again.
If the dirt can not be wiped off, absorbent cotton wetted a little with normal-hexane or petroleum
benzene can be used for wiping the panel.
Be careful not to spill this solvent into the inside of LCD module. Driver ICs and PCB area used
inside LCD module may be damaged by the solvent.
(5) AVOID THE DEWING OF WATER CONDENSATION
Wipe off a spot or spots of water of mist and chemicals of mist on LCD panel softly with absorbent
cotton or another cloth as soon as possible if happened, otherwise discoloration or stain may be
caused. If water invade into LCD module may cause its damages.
(6) Do not expose LCD module to the gas (which is not normally contained in the atmosphere),it may
cause mis-operation or defects.
(7) DO NOT APPLY MECHANICAL FORCES.
Do not bend or twist LCD module even momentary when LCD module is installed an enclosure of
the system. Bending or twisting LCD module may cause its damages.
Make sure to design the enclosure that bending/twisting forces are not applied to LCD module
when it is installed in the system.
Refrain from strong mechanical shock like dropping form the working bench or knocking against
hard object.
These may cause glass of the panel crack, damage of FL or other mis-operation.
(8) Refrain from excessive force like pushing the surface of LCD panel. This may cause damage of the
panel or electrical parts on PCB.
(9) Do not put heavy object such as tools, books, etc., and do not pile up LCD modules.
Be careful not to touch surface of the polarizer laminated to the panel with any hard and sharp
object. The polarizer is so soft that it can easily scratched, even the protect film covers it.
(10) When inserting or disconnecting the connectors to LCD module, be sure not to apply force against
PCB, nor connecting cables, otherwise internal connection of PCB and TAB drivers may be
damaged.
Do not fasten screws while putting cables like those for interface or FL between LCD module and
the enclosure.
Make sure to insert the module FL connector to the inverter connector in correct position.
If incorrect, this may cause smoke or burn or electrical parts by high voltage of FL circuit.

(11) Be careful not to pull the FL cables of the backlight in order to avoid mechanical damage in FL
lamp and soldering area.
Be careful not to pull or not to hurt the FPC (Flexible Printed Circuit) cables.
(12) Power supplies should always be turned off in assembling process.
Do not connect or disconnect the power cables and connectors with power applied to LCD module.
This may cause damage of module circuit.
The signal should be applied after power is turned on. And the signal should be removed before
power supplies are turned off.
14.4 For Transportation and storage
(1) Do not store LCD module in high temperature, especially in high humidity for a long time
(approximately more than one month).
It is recommended to store LCD module where the temperature is in the range of 0 to 35
degrees Celsius and the relative humidity is lower than 70%.
(2) Store LCD module without exposure to direct sunlight or fluorescent lamps in order to prevent
the module from strong ultra violet ray.
(3) Avoid condensation of water on LCD module; otherwise it may cause mis-operation or defects.
Keep away LCD module from such ambient.
(4) In case of transportation of storage after opening the original packing. LCD module is
recommended to be repacked into original packaging with the same method, especially with
the same kind of desiccant.
