[For handling and system design]
(1) Handle with care as glass is used in this LCD panel. Dropping or contact against hard object may cause cracks or
chips.
(2) Be careful to handle this LCD panel in order to avoid injury yourself by panel`s edge as this panel is made of glass
and might be a sharp edge.
(3) Do not scratch the surface of the polarizer as it is easily damaged.
(4) Water droplets on the polarizer must be wiped off immediately as they may cause color changes, or other defects if
remained for a long time.
(5)Do not leave the LCD panel in direct sun or under ultraviolet ray.
(6) To clean LCD panel surface, wipe clean with absorbent cotton or soft cloth. If further cleaning is needed, use IPA
(isopropyl alcohol) and wipe clean lightly on surface only. Do not use organic solvents as it may damage the LCD
panel terminal area which uses organic material. Also, do not directly touch with finger. When the terminals cleaning
are needed, those should be wiped by a soft cloth or a cotton swab without directly touching by hand.
(7) Do not expose gate driver, etc. on the panel (circuit area outside panel display area) to light as it may not operate
properly. Design that shields gate driver, etc. from light is required when mounting the LCD module.
(8) To avoid circuit failure, do not touch panel terminal area.
(9) Support for the LCD panel should be carefully designed to avoid stress that exceeds specification on glass surface.
(10) When handling LCD module and assembling them into cabinets, be noted that storage in the environment of
oxidization or deoxidization gas and the use of such materials as reagent, solvent, adhesive, resin, and etc. which
generate these gasses, may cause corrosion and discoloration of LCD modules.
(11)To avoid picture uniformity failure, do not put a seal or an adhesive material on the panel surface.
(12) Do not use chloroprene rubber as it generates chlorine gas and affects reliability in LCD panel connective area.
(13) Protective film is attached to the surface of polarizer on LCD panel to prevent scratches or other damages.
Remove this protective film before use. In addition, do not attach the protective film which is removed from LCD
module again. When the LCD panel which has the reattached protective film is needed to storage for a long time, the
polarizer might have a damage with picture quality failure.
(14) Panel is susceptible to mechanical stress and such stress may affect the display. Place the panel on flat surface
to avoid stress caused by twist, bend, etc.
(15) When transporting LCD panels, secure them in LCD panel tray to avoid mechanical stress. The tray should be
conductive to protect LCD panels from static charge.
Material used in set or epoxy resin (amine type hardening agent) from packaging, and silicon adhesive
(dealcoholized or oxime) all release gas which may affect quality of the polarizer . Do confirm compatibility with
user materials.
(16) As this LCD module is composed electronic circuits, it is sensitive to electrostatic discharge of 200V or more.
Handle with care using cautions for the followings:
z
Operators
Operators must wear anti-static wears to prevent electrostatic charge up to and discharge from human
body.

Equipment and containers
Process equipment such as conveyer, soldering iron, working bench and containers may possibly generate
electrostatic charge up and discharge. Equipment must be grounded through 100Mohms resistance. Use
ion blower.
z
Floor
Floor plays an important role in leaking static electricity generated in human body or equipment. If the floor
is made of insulated material (such as polymer or rubber material), such static electricity may charge.
Proper measure should be taken to avoid static electricity charge (electrostatic earth: 100Mohms).There is
a possibility that the static electricity is charged to them without leakage in case of insulating floor, so the
electrostatic earth:1×108Ω should be made.
z
Humidity
Humidity in work area relates to surface resistance of the persons or objects that generate electrostatics,
and it can be manipulated to prevent electrostatic charge. Humidity of 40% or lower increases electrostatic
earth resistance and promotes electrostatic charging. Therefore, the humidity in the work area is
recommended to be kept above 40%. Specifically for film peeling process or processes that require human
hands, humidity is recommended to be kept above 50% and use electricity removal blower.
z
Transportation/Storage
Containers and styroform used in transporation and storage may charge electrostatic (from friction and
peeling) or electrostatic charge from human body, etc. may cause containers and styroform to have induced
charge. Proper electrostatic measure should be taken for containers and storage material.

[For operating LCD module]
(1) Do not operate the LCD panel under outside of electrical specification. Otherwise LCD panel may be damaged.
(2) Do not use the LCD panel under outside of specified driving timing chart. Otherwise LCD panel may not have
proper picture quality.
(3) In order to prevent image retention it is our recommendation that an inverted display image (preferred) or white
pattern be introduced as a refresh at a minimum for 1hour over a 24 hour period. In refreshing, display can be
written white image by addressing white data as normal driving for this panel or DISP signal would be set as “Low”.
(4) If LCD module takes a static electricity, as the display image which is written into pixel memory might not be
displayed, Data update should be executed frequently.
(5) It is neither a breakdown nor a defective indication though very slight change in black level might be periodically
seen in a black part on the black display image according to the source of light (angle of the luminance and the
source of light).
[Precautions for Storage]
(1) After opening the package, do not leave the LCD panel in direct sun or under strong ultraviolet ray. Store in dark
place.
(2) In temperature lower than specified rating, liquid crystal material will coagulate. In temperature higher than
specified rating, it isotropically liquifies. In either condition, the liquid crystal may not recover its original condition.
Store the LCD panel in at or around room temperature as much as possible.
Also, storing the LCD panel in high humidity will damage the polarizer. Store in normal room temperature as much
as possible.
(3) Keeping Method
a. Don't keeping under the direct sunlight.
b. Keeping in the tray under the dark place.

[Other Notice]
(1) Operation outside specified environmental conditions cannot be guaranteed.
(2) As power supply (VDD-GND、VDDA-GND) impedance is lowered during use, bus controller should be inserted
near LCD module as much as possible.
(3) The polarizer is applied over LCD panel surface. Liquid crystal inside LCD panel deteriorates with ultraviolet ray.
The panel should not be left in direct sun or under strong ultraviolet ray for prolonged period of time even with the
polarizer film.
(4) Disassembling the LCD module will cause permanent damage to the module. Do not disassemble the module.
(5) If LCD panel is broken, do not ingest the liquid crystal from the broken panel. If hand, leg, or clothes come in
contact with liquid crystal, wash off immediately with soap.
(6) ODS (specific chlorofuorocarbon, specific halon, 1-1-1 trichloroethane, carbon tetrachloride) are not used or
contained in material or all production processes of this product.
(7) Observe all other precautionary requirements in handling general electronic components.
[Discarding liquid crystal modules]
LCD Panel
: Dispose of as glass waste. This LCD module contains no harmful substances.
The liquid crystal panel contains no dangerous or harmful substances.
This liquid crystal panel contains only an extremely small amount of liquid crystal
(approximately 100mg) and therefore it will not leak even if the panel should
break.
Its median lethal dose (LD50) is greater than 2,000 mg/kg and a mutagenetic
(Aims test: negative) material is used.

8-2) FPC Bend Specification
When bending FPC, bend where specified in Condition (1) and the bend R should be more than R specified in Condition
(2). FPC is not to contact glass edge, and there should be no stress to connective area between panel and FPC.
Condition (1) FPC bend recommended area: more than 0.8mm from glass edge.
Condition (2) Minimum bend R: Inner diameter R0.45

Humidity: 60%RH or lower (at 40℃)
There should be no condensation at low temperature and high humidity.
・
Atmosphere: No harmful gas, such as acid or alkali, which causes severe corrosion on
electronic parts and wiring, are to be detected.
・
Period: About 3 months
・
Opening the package: in order to prevent electrostatic damage to TFT modules, room
humidity should be made over 50%RH and take effective measure such as use of earth when
opening the package.
