10. PRECAUTION

Fig.1 Cross sectional view of a monitor set

Please pay attention to the followings when a TFT module with a back-light unit is used,
handled and mounted.

10.1 PRECAUTION TO HANDLING AND MOUNTING

(1) Applying strong force to a part of the module may cause partial deformation of frame or mold,

and cause damage to the display.

(2) The module should gently and firmly be held by both hands. Never hold by just one hand in order

to avoid any internal damage. Never drop or hit the module. Never press the glass surface.

(3) The module should be installed with mounting holes of a module. Usage style of this product is

limited to Landscape mode. If not CCFL life time may become shorter. Screw torque should be
within spec.

(4) Uneven force such as twisted stress should not be applied to a module when a module is mounted

on the cover case. The cover case must have sufficient strength so that external force can not be
transmitted directly to a module.

(5) It is recommended to leave about 1mm space between a module and a cover case so that partial

force is not applied to a module.

www.panelook.com

Cover case

(6) The edge of a cover case should be located inside more than 1mm from the edge of a module front

frame.

(7) For the surface protection purpose, place transparent protection plate. Then this plate should not

be touched to LCD active area.

(8) Materials included acetic acid and chlorine should not be used for a cover case as well as other

parts and boards near a module. Acetic acid attacks a polarizer. Chlorine attacks electric circuits
due to electro-chemical reaction.

(9) The polarizer on a TFT cell should carefully be handled due to its softness, and should not be

touched, pushed or rubbed with glass, tweezers or anything harder than HB pencil lead.
The surface of a polarizer should not be touched and rubbed with bare hand, greasy clothes or
dusty clothes.

(10) The surface of a polarizer should be gently wiped with absorbent cotton, chamois or other soft

materials slightly contained petroleum benzene when the surface becomes dirty. Isopropyl alcohol
as cleaning chemicals is recommended in order to clean adhesives which fix front/rear polarizers
on a TFT cell. Other cleaning chemicals such as acetone, toluene and Normal-hexane should not
be used to clean adhesives because they cause chemical damage to a polarizer.

(11) Saliva or water drops should be immediately wiped off. Otherwise, the portion of a polarizer may

be deformed and its color may be faded.

(12) The module should not be opened or modified. It may not work properly when module is modified.

If the module is once opened or modified, warranty of the module becomes invalid and Hitachi
doesn't guarantee its quality and reliability.

Global LCD Panel Exchange Center

(13) Metal frame of a module should not be handled with bare hand or dirty gloves. Otherwise,

color of a metal frame may become dirty during its storage. It is recommended to use clean
soft gloves and clean finger stalls when a module is handled at incoming inspection process and

production (assembly) process.
(14) Lamp (CCFL) cables should not be pulled and held.
(15) During transportation, do not place LCD module at face down or face up. Because strong shock

may cause functional failure at above condition.

10.2 PRECAUTION TO OPERATION

(1) The ambient temperature near the operated module should be satisfied with the absolute

maximum ratings. Unless it meets the specifications, sufficient cooling system should be

adopted to system.

(2) The spike noise causes the miss-operation of a module. The level of spike noise should be

as follows: -200mV d over- and under- shoot of VDD d +200mV

VDD including over- and under- shoot should be satisfied with the absolute maximum ratings.

Ripple voltage of inverter should be within electrical characteristics spec.

(3) Optical response time, luminance and chromaticity change depend on the temperature of a TFT

module. Optical response time becomes longer at lower temperature operation.

(4) Starting lamp voltage becomes higher under low temperature condition. Also saturation time

from power on will become longer.

(5) Sudden temperature change may cause dew on and/or in the a module. Dew makes damage to a

polarizer and/or electrical contacting portion. Dew causes deterioration of display quality.

(6) Fixed pattern on display for a long time may cause after-image. It will be recovered with time.
(7) A module has high frequency circuits. Sufficient suppression to electromagnetic interference

should be done by system manufacturers. Grounding and shielding methods may be effective to

minimize the interference.

(8) Noise may be heard when a back-light is operated. If necessary, sufficient suppression should be

done by system manufacturers.

(9) The Interface connector should not be connected or removed while a main system works.

Otherwise, it may cause functional failure.

www.panelook.com

10.3 ELECTROSTATIC DISCHARGE CONTROL

(1) Since a module consists of a TFT cell and electronic circuits with CMOS-ICs, which are very weak

to electrostatic discharge, person who is handling a module should be grounded through

adequate methods such as a list band. I/F connector pins should not be touched directly with

bare hands.

(2) Protection film for a polarizer on a module should be slowly peeled off so that the electrostatic

charge can be minimized.

10.4 PRECAUTION TO STRONG LIGHT EXPOSURE

(1) A module should not be exposed under strong light. Otherwise, characteristics of a polarizer and

color filter in a module may be degraded.

10.5 PRECAUTION OF STORAGE, PACKAGE AND TRANSPORTATION
When modules such as service purposes, are stored for a long time, following precautions
should be taken care of :

(1) Modules should be stored in a dark place. It is prohibited to apply sunlight or fluorescent light

during storage. Modules should be stored at 5 to 35°C at normal humidity (60%RH or less).

(2) The surface of polarizer should not come in contact with any other object. It is recommended

that modules should be stored in the Hitachi's shipping box.

10.6 PRECAUTION OF HANDLING PROTECTION FILM

(1) The protection film for polarizer should be pealed off slowly and carefully by person who is

electrically grounded with adequate methods such as a list band. Besides, ionized air should be
blown over during peeling action. Dusts on a polarizer should be blown off by an ionized nitrogen
gun and so on.

(2) The protection film should be peeling off without rubbing it to the polarizer. Because, if the film is

rubbed together with the polarizer, since the film is attached to the polarizer with a small amount
of adhesive, the adhesive may remain on a polarizer.

(3) LCD module should not be stored at high temperature or high humidity condition. Because if

protection film and polarizer film are attached long time Mura (non-uniformity) may occur.

(4) Stain can be removed easily with Isopropyl alcohol. Stain or its vestige

on the polarizer should be wiped off with absorbent cotton or other soft materials such as chamois
slightly contained Isopropyl alcohol.

www.panelook.com

10.7 SAFETY

(1) Since a TFT cell and lamps are made of glass, handling of the broken module should be taken

care sufficiently in order not to be injured.

Hands should be washed sufficiently when liquid crystal material is attached to hands.
(2) The module should not be disassembled during operation so that back-light drives by high voltage.
(3) Inverter for driving CCFL should have over current/voltage detect circuit in case back-light failure

happens. Also protection circuit should be verified on system side.

10.8 ENVIRONMENTAL PROTECTION

(1) The TFT module contains cold cathode fluorescent lamps. Please follow local ordinance or

regulations for its disposal.
(2) Flexible circuits board and printed circuits board used in a module contain small amount of lead.

Please follow local ordinance or regulations for its disposal.

10.9 USE RESTRICTIONS AND LIMITATIONS

(1) This product is not authorized for use in life support devices or systems, military applications or

other applications which pose a significant risk of personal injury.
(2) In no event shall Hitachi Displays, Ltd., be liable for any incidental, indirect or consequential

damages in connection with the installation or use of this product, even if informed of the

possibility thereof in advance. These limitations apply to all causes of action in the aggregate,

including without limitation breach of contact, breach of warranty, negligence, strict liability,
