12. 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 LED driver circuit board by using
mounting hole of rear side with a screw clamping torque less than 0.5 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 stress on LCD and not to wrench
module. If customer uses compression mounting, please evaluate housing case with LCD
carefully to avoid image quality issue caused by mechanical stress.
(b) Under high temperature environment, performance and life time of LED may heavily
shorten. When you design with our LCD product, please consider radiating heat and
ventilation for good heat management.
(c) 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.
(d) 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.
(e) Design the LED driver location and connector position carefully so as not to give stress to
LED backlight cable.
(f) Keep sufficient clearance between LCD module and the others parts, such as inverter and
speaker so as not to interfere the LCD module. Approximately 1.0 mm of the clearance in the
design is recommended.
(g) To avoid local elevation/decrease of temperature, considering location of heating element,
heat release, thermal design should be done.
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 wipe off LCD panel surface with absorbent cotton or soft cloth in case of it being soiled.
e. 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.

Specification
f. Please do not take a LCD module to pieces and reconstruct it. Resolving and reconstructing
modules may cause them not to work well.
g. 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.
h. Please handle metal frame carefully because edge of metal frame is very sharp.
i. Please connect the metal frame of LCD module to GND in order to minimize the effect of external
noise and EMI.
j. Be sure to connect the cables and the connecters 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. The interface signal speed is very high. Please pay attention to transmission line design and
other high speed signal precautions to satisfy signal specification.
d. Condensation might happen on the surface and inside of LCD module in case of sudden change
of ambient temperature. Please take care so as not to cause any damage mentioned on (1)-d.
e. Please pay attention not to display the same pattern for very long time. Image sticking might
happen on LCD. Although image sticking may disappear as the operation time proceeds, screen
saver function is recommended not to cause image sticking.
f. 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
LCD should be stored in the room temperature environment with normal humidity. The LCD
inventory should be processed by first-in first-out method.
(5) SAFETY PRECAUTIONS
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 LED backlight cable.
d. LED driver should be designed carefully to limit or stop its function when over current is
detected on the LED.
(6) OTHERS
a. A strong incident light into LCD panel may cause deterioration to polarizer film, color filter, and
other materials, which will degrade the quality of display characteristics. Please do not expose

LCD module under strong Ultraviolet rays for a long time.
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 handling, please see and obey with the packaging specification datasheet.
