*3) Lamp frequency of inverter may produce interferenc e with horizontal synchr onous frequency,

and this may cause horizontal beat on the d is play. 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.

*6) Please use the inverter which has symmetrical current wave form as follows,

The degree of unbalance: less than 10%

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 invertor circuit board by using
mounting hole of rear side with a screw clamping torque less than 0.2 Nm.

b. Please design display hous ing 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 cabl e and ferrite plate , are installed underneath th e LCD

module, still sufficient clearance is required, such as 0.5mm. This clearance is, especially, to
be reconsidered when the additional parts a re 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 c learance in the
design i s recommen ded.

(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 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 surfa ce variation and color change.
g. Please do not take a LCD module to pieces and reconstruct it. Resolving and reconstructing mod-

ules 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 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 LC D module. Th ey ar e adjusted to th e 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.

www.panelook.com

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 c ircuit 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 suc h

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 c rush LCDs into pieces

and wash them off with solvents such as acetone and ethanol, which should later be burned.
b. If any l iquid leaks out of a damaged glass cel l and comes in c ontact with th e hands, wash off

thoroughly with soap and water.
c. Be sure to turn off the power s u pply when inserting or disconnecting the cable.
d. Inverter should be designed carefully so as not to keep working in case of detecting over cur rent

or open circuit on the lamp.

(6) OTHERS

a. A strong incident light into L CD 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 Ultra violet ra ys 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, 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 6 boxes. (They ar e not desig ned so.) And ple ase do not

turn over.

(c) Please handle packaging box with care not to give them sudden shock and vibrations. And

www.panelook.com

also please do not throw them up.

(d) Packag ing bo x and inn er case f or LCDs ar e made of c ardboard. S o please pay attent ion n ot

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