10. HANDLING PRECAUTIONS FOR TFT-LCD MODULE
Please pay attention to the followings in handling TFT-LCD products.
10.1 ASSEMBLY PRECAUTION
(1) Please use the mounting hole on the module side in installing and do not beading or
wrenching LCD in assembling. And please do not drop, bend or twist LCD module in
handling.
(2) Please design display housing in accordance with the following guidelines.
Housing case must be destined carefully and do not to put stresses on LCD all
sides or wrench module. The stresses may cause non-uniformity even if there is
no non-uniformity statically.
Keep sufficient clearance between LCD module back surface and housing when
the LCD module is mounted. Approximately 1.0 mm of the clearance in the design
is recommended taking into account the tolerance of LCD module thickness and
mounting structure height on the housing.
When some parts, such as, FPC cable and ferrite plate, are installed underneath
the LCD module, still sufficient clearance is required, such as 0.5mm. This
clearance is, especially, to be reconsidered when the additional parts are
implemented for EMI countermeasure.
Design the inverter location and connector position carefully so as not to put
stress on lamp cable.
Keep sufficient clearance between LCD module and the other parts, such as
inverter and speaker so as not to interface the LCD module. Approximately
1.0mm of the clearance in the design is recommended.
(3) Please do not push or scratch LCD panel surface with any-thing hard. And do not soil
LCD panel surface by touching with bare hands. ( Polarizer film and surface of LCD
panel are easy to be flawed.)
(4) Please do not press any parts on the rear side such as source TCP, gate TCP, control
circuit board and FPC during handling the LCD module. If pressing rear part could not
be avoided, handle the LCD module with care not to damage them.
(5) Please wipe out LCD panel surface with absorbent cotton or soft clothe in case of it
being soiled.
(6) Please wipe out drops of adhesives like saliva and water on LCD panel surface
immediately. They might damage to cause panel surface variation and color change.
(7) Please do not take a LCD module to pieces and reconstruct it. Resolving and
reconstructing modules may cause them not to work well.
(8) Please do not touch metal frames with bare hands and soiled gloves. A color change of
the metal frames can happen during a long preservation of soiled LCD modules.

(9) Please pay attention to handling lead wire of backlight so that it is not tugged in
connecting with inverter.
10.2 OPERATING PRECAUTIONS
(1) Please be sure to turn off the power supply before connecting and disconnecting signal
input cable.
(2) Please do not change variable resistance settings in LCD module. They are adjusted to
the most suitable value. If they are changed, it might happen LCD does not satisfy the
characteristics specification.
(2-1) Please consider that LCD backlight takes longer time to become stable of
radiation characteristics in low temperature than in room temperature.
(2-2) A condensation might happen on the surface and inside of LCD module in case
of sudden change of ambient temperature.
(2-3) Please pay attention to displaying the same pattern for a very long time. Image
might stick on LCD. If then, time going on can make LCD work well.
(2-4) Please obey the same caution descriptions as ones that need to pay attention
to ordinary electronic parts.
10.3 PRECAUTIONS WITH ELECTROSTATICS
(1) This LCD module use CMOS-IC on circuit board and TFT-LCD panel, and so it is easy
to be affected by electrostatics. Please be careful with electrostatics by the way of your
body connecting to the ground and so on.
(2) Please remove protection film very slowly on the surface of LCD module to prevent from
electrostatics occurrence.
10.4 STORAGE PRECAUTIONS
(1) When you store LCD for a long time, it is recommended to keep the temperature
between 0 ~40 without the exposure of sunlight and keep the humidity less than
90%RH.
(2) Please do not leave the LCD in the environment of high humidity and high temperature
such as 60 90%RH.
(3) Please do not leave the LCD in the environment of low temperature (can not lower than
-20 ).

10.5 SAFETY PRECAUTIONS
(1) When you waste LCD, it is recommended to crush damaged or unnecessary LCD into
pieces and wash them off with solvents such as acetone and ethanol, which should later
be burned.
(2) If any liquid leaks out of a damaged-glass cell and comes in contact with the hands,
wash off thoroughly with soap and water.
10.6 OTHERS
(1) A strong incident light into LCD panel might cause display characteristics' changing
inferior because of polarizer film, color filter, and other materials becoming inferior.
Please do not expose LCD module direct sunlight Land strong UV rays.
(2) Please pay attention on the side of LCD module do not contact with other materials in
preserving it alone.
(3) For the packaging box, please pay attention to the followings:
Packaging box and inner case for LCD are designed to protect the LCD from the
damage or scratching during transportation. Please do not open except picking
LCD up from the box.
Please do not pile them up more than 3 boxes. (They are not designed so.) And
please do not turn over.
Please handle packaging box with care not to give them sudden shock and
vibrations. And also please do not throw them up.
Packing box and inner case for LCD are made of cardboard. So please pay
attention not to get them wet. (Such as keep them way the high humidity or wet
place.)
