11. HANDLING PRECAUTIONS FOR TFT-LCD MODULE
Please pay attention to the followings in handling TFT-LCD products;
(1) ASSEMBLY PRECAUTION
a. Please mount the LCD module by using mounting hole with a screw clamping torque less than 0.5
Nm. Please do not bend or wrench the LCD module in assembling. Please do not drop, bend or twist
the LCD module in handling. Please mount the invertor circuit board by using mounting hole of
rear side with a screw clamping torque less than 0.2 Nm.
b. Please design display housing in accordance with the following guide lines.
(a) Housing case must be designed carefully so as not to put stresses on LCD all sides and not to
wrench module. The stresses may cause non-uniformity even if there is no non-uniformity
statically.
(b) Keep sufficient clearance between LCD module back surface and housing when the LCD
module is mounted. Approximately 1.0mm of the clearance in the design is recommended taking
into account the tolerance of LCD module thickness and mounting structure height on the
housing.
(c) 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.
(d) Design the inverter location and connector position carefully so as not to give stress to lamp
cable, or not to interface the LCD module by the lamp cable.
(e) Keep sufficient clearance between LCD module and the others 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.
c. Please do not push or scratch LCD panel surface with anything hard. And do not soil LCD panel
surface by touching with bare hands. (Polarizer film, surface of LCD panel is easy to be flawed.)
d. Please do not press any parts on the rear side such as source TCP, gate TCP, control circuit board
and FPCs during handling LCD module. If pressing rear part is unavoidable, handle the LCD
module with care not to damage them.
e. Please wipe off LCD panel surface with absorbent cotton or soft cloth in case of it being soiled.
f. Please wipe off drops of adhesives like saliva and water on LCD panel surface immediately. They
might damage to cause panel surface variation and color change.
g. Please do not take a LCD module to pieces and reconstruct it. Resolving and reconstructing modules
may cause them not to work well.
h. 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.

www.panelook.com
i. Please pay attention to handling lead wire of backlight so that it is not tugged in connecting with
inverter.
j. Please connect the metal frame of LCD module to GND in order to minimize the effect of external
noise and EMI.
k. Be sure to connect the cables and the connectors correctly.
(2) OPERATING PRECAUTIONS
a. Please be sure to turn off the power supply before connecting and disconnecting signal input cable.
b. 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.
c. LCD backlight takes longer time to become stable of radiation characteristics in low temperature
than in room temperature.
d. The interface signal speed is very high. Please pay attention to transmission line design and other
high speed signal precautions to satisfy signal specification.
e. A condensation might happen on the surface and inside of LCD module in case of sudden change of
ambient temperature.
f. Please pay attention not to display the same pattern for very long time. Image might stick on LCD.
Even if image sticking happens, it may disappear as the operation time proceeds.
g. Please obey the same safe instructions as ones being prepared for ordinary electronic products
(3) PRECAUTIONS WITH ELECTROSTATICS
a. 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.
b. Please remove protection film very slowly from the surface of LCD module to prevent from
electrostatics occurrence.
(4) STORAGE PRECAUTIONS
a. Please do not leave the LCDs in the environment of high humidity and high temperature such as
60°C90% RH.
b. Please do not leave the LCDs in the environment of low temperature; below -20°C.
One step solution for LCD / PDP / OLED panel application: Datasheet, inventory and accessory!
www.panelook.com
a. When you waste damaged or unnecessary LCDs, it is recommended to crush LCDs into pieces and
wash them off with solvents such as acetone and ethanol, which should later be burned.
b. If any liquid leaks out of a damaged glass cell and comes in contact with the hands, wash off
thoroughly with soap and water.
c. Be sure to turn off the power supply when inserting or disconnecting the cable.
d. Inverter should be designed carefully so as not to keep working in case of detecting over current or
open circuit on the lamp.
(6) OTHERS
a. 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 and strong UV rays.
b. Please pay attention to a panel side of LCD module not to contact with other materials in
preserving it alone.
c. For the packaging box, please pay attention to the followings;
(a) Packaging box and inner case for LCD are designed to protect the LCDs from the damage or
scratching during transportation. Please do not open except picking LCDs up from the box.
(b) Please do not pile them up more than 5 boxes. (They are not designed so.) And please do not
turn over.
(c) Please handle packaging box with care not to give them sudden shock and vibrations. And also
please do not throw them up.
(d) Packaging box and inner case for LCDs are made of cardboard. So please pay attention not to
get them wet. (Such like keeping them in high humidity or wet place can occur getting them
wet.)
