*3) Lamp frequency of inverter may produce interference with horizontal synchronous frequency,
and this may cause horizontal beat on the display. Therefore, please adjust lamp frequency, and
keep inverter as far from module as possible or use electronic shielding between inverter and

These items are measured using CS1000(MINOLTA) for color coordinates, EZContrast(ELDIM) for
viewing angle and CS1000 or BM-5A(TOPCON) for others under the dark room condition (no
ambient light) after more than 30 minutes from turning on the lamp unless noted.
Condition: IL = 14.0 mArms, FL = 55 kHz
Measurement method for luminance and color coordinates is as follows.
Photodetector
Luminance :T=2q (BM-5A)
Color coordinates :T=1q (CS1000)

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
(recommended value: 0.3 Nm). Please do not bend or wrench the LCD module in assembling.
Please do not drop, bend or twist the LCD module in handling.
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 and not to
wrench module.
(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 interfere 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 interfere the LCD module. Approximately 1.0mm of the clearance in
the design is recommended.
(f) 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.
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 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
www.panelook.com
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. Please take care so as not to cause any damage mentioned
on (1)-e.
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
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 cable.

d. Inverter should be designed carefully to limit or stop its function when over current is detected
on the on the lamp.
(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.
