*3) Lamp frequency of inverter may produce interferenc e 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
module to avoid the interference.

*4) Lamp life time is defined as the time either when the brightness becomes 50% of the initial

value, or when the starting lamp voltage does not meet the value specified in this ta ble.

*5) The life time of the backlight depends on the ambient temperature. The life time will decrease

under low/high temperature.

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

(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 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) Whe n some parts, su ch as, FPC c able and fer rite pl ate, ar e instal led un derneath 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.

(f) To avoid local elevation/decrease of temperature, considering location of heating element,

heat release, thermal design should be d one.

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 FP Cs 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 dama ge to cause panel surface variation and color change.
g. Please do not take a LCD module to pieces and reconstruct it. Resolving and r econstructing

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.
i. Please handle metal frame carefully because edge of metal frame is very sharp.

j. Please pay attention to handling lead wire of backlight so that it is not tugged in connecting

with inverter.
k. Please connect the metal frame of LCD module to GND in order to minimize the effect of

external noise and EMI.
l. Be su re 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. 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 p roceeds.
g. Please obey the same sa fe ins tructions as ones being prepared for ordinary electronic products.

(3) PRECAUTIONS WITH ELECTROSTATICS

a. This LCD module use CMOS-I C on circ uit 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.

(5) SAFETY PRECAUTIONS

a. When you waste damaged or unnecessary LCDs, it is recommended to crush LCDs into piec es

and wash them off with solvents such as acetone and ethanol, which should later be burned.
b. If any liquid leaks out of a dam aged glass cel l and comes i n contact wi th the hands, wash o ff

thoroughly with soap and water.
c. Be sure to turn off the power supply when inserting or di sconnecting t he 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 st rong 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 a n d inner case for LCDs are made of cardboard. So p lease pay attention not

to get them wet. (Such like keeping them in high humidity or wet place can occur getting
them wet.)
