2) 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
module to avoid the interference.
3) 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 table.
4) 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 use the mounting hole on the module in installing and do not bending or wrenching
LCD in assembling. And please do not drop, bend or twist 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.
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 damage to ca u se pan el surface variation and color change .
g. Please do not take a LCD module to pieces and rec onstruct it. Resolving and reconstructin g
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 to avoid getting hurt because edge of metal frame is very
sharp.

temperature than in room temperature.
d. A condensation might happen on the surface and inside of LCD module in case of sudden
change of ambient temperature.
e. Please pay attention not to display the same pattern for very long time. Image mig ht stick on
LCD. Even if image sticking happens, it may disappear as the op erat ion time p roceeds.
f. Please obey the same safe instructions as ones being prepared for ordinary electronic products.
(3) PRECAUTIONS WITH ELECTROSTATICS
