NOTICE
These specification sheets are the proprietary product of SHARP CORPORATION ("SHARP) and include materials protected
under copyright of SHARP. Do not reproduce or cause any third party to reproduce them in any form or by any means,
electronic or mechanical, for any purpose, in whole or in part, without the express written permission of SHARP.
The application examples in these specification sheets are provided to explain the representative applications of the device and
are not intended to guarantee any industrial property right or other rights or license you to use them. SHARP assumes no
responsibility for any problems related to any industrial property right of a third party resulting from the use of the device.
The device listed in these specification sheets was designed and manufactured for use in Telecommunication equipment
(terminals)
In case of using the device for applications such as control and safety equipment for transportation (aircraft, trains,
automobiles, etc. ), rescue and security equipment and various safety related equipment which require higher reliability and
safety, take into consideration that appropriate measures such as fail-safe functions and redundant system design should be
taken.

telecommunication equipment (trunk lines), nuclear power control equipment and medical or other equipment for life support.
SHARP assumes no responsibility for any damage resulting from the use of the device which does not comply with the
instructions and the precautions specified in these specification sheets.
Contact and consult with a SHARP sales representative for any questions about this device.
[For handling and system design]
(1) Do not scratch the surface of the polarizer film as it is easily damaged.
(2) If the cleaning of the surface of the LCD panel is necessary, wipe it swiftly with cotton or other soft cloth. Do not use
organic solvent as it damages polarizer.
(3) Water droplets on polarizer must be wiped off immediately as they may cause color changes, or other defects if remained for
a long time.
(4) Since this LCD panel is made of glass, dropping the module or banging it against hard objects may cause cracks or
fragmentation.
(5) Certain materials such as epoxy resin (amine’s hardener) or silicone adhesive agent (de-alcohol or de-oxym) emits gas to
which polarizer reacts (color change). Check carefully that gas from materials used in system housing or packaging do not hart
polarizer.
(6) Liquid crystal material will freeze below specified storage temperature range and it will not get back to normal quality even
after temperature comes back within specified temperature range. Liquid crystal material will become isotropic above specified
temperature range and may not get back to normal quality. Keep the LCD module always within specified temperature range.
(7) Do not expose LCD module to the direct sunlight or to strong ultraviolet light for long time.
(8) If the LCD driver IC (COG) is exposed to light, normal operation may be impeded. It is necessary to design so that the light
is shut off when the LCD module is mounted.
(9) Do not disassemble the LCD module as it may cause permanent damage.
(10) As this LCD module contains components sensitive to electrostatic discharge, be sure to follow the instructions in below.
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.
Floor
Floor is an important part to leak static electricity which is generated from human body or equipment.
There is a possibility that the static electricity is charged to them without leakage in case of insulating floor, so the
countermeasure(electrostatic earth:1×108Ω) should be made.
Humidity
Proper humidity of working room may reduce the risk of electrostatic charge up and discharge. Humidity should be kept
over 50% all the time.
Transportation/storage
Storage materials must be anti-static to prevent causing electrostatic discharge.
Others
Protective film is attached on the surface of LCD panel to prevent scratches or other damages. When removing this
protective film, remove it slowly under proper anti-ESD control such as ion blower.
(11) Hold LCD very carefully when placing LCD module into the system housing. Do not apply excessive stress or pressure
to LCD module. Do not to use chloroprene rubber as it may affect on the reliability of the electrical interconnection.
(12) Do not hold or touch LCD panel to flex interconnection area as it may be damaged.
(13) As the binding material between LCD panel and flex connector mentioned in 12) contains an organic material, any type
of organic solvents are not allowed to be used. Direct contact by fingers is also prohibited.
(14) When carrying the LCD module, place it on the tray to protect from mechanical damage. It is recommended to use the
conductive trays to protect the CMOS components from electrostatic discharge. When holding the module, hold the Plastic
Frame of LCD module so that the panel, COG and other electric parts are not damaged.

(15) Do not touch the COG‘s patterning area. Otherwise the circuit may be damaged.
(16) Do not touch LSI chips as it may cause a trouble in the inner lead connection.
(17) Place a protective cover on the LCD module to protect the glass panel from mechanical damages.
(18) LCD panel is susceptible to mechanical stress and even the slightest stress will cause a color change in background. So
make sure the LCD panel is placed on flat plane without any continuous twisting, bending or pushing stress.
(19) Protective film is placed onto the surface of LCD panel when it is shipped from factory. Make sure to peel it off before
assembling the LCD module into the system. Be very careful not to damage LCD module by electrostatic discharge when
peeling off this protective film. Ion blower and ground strap are recommended.
(20) Make sure the mechanical design of the system in which the LCD module will be assembled matches specified viewing

angle of this LCD module.
(21) This LCD module does not contain nor use any ODS (1,1,1-Trichloroethane, CCL4) in all materials used, in all
production processes.
[For operating LCD module]
(1) Do not operate or store the LCD module under outside of specified environmental conditions.
(2) At the shipment, adjust the contrast of each LCD module with electric volume. LCD contrast may vary from panel to panel
depending on variation of LCD power voltage from system.
(3) As opt-electrical characteristics of LCD will be changed, dependent on the temperature, the confirmation of display quality
and characteristics has to be done after temperature is set at 25 °C and it becomes stable.
[Precautions for Storage]
(1) Do not expose the LCD module to direct sunlight or strong ultraviolet light for long periods. Store in a dark place.
(2) The liquid crystal material will solidify if stored below the rated storage temperature and will become an isotropic liquid
if stored above the rated storage temperature, and may not retain its original properties. Only store the module at normal
temperature and humidity (25±5°C,60±10%RH) in order to avoid exposing the front polarizer to chronic humidity.
(3) Keeping Method
a. Don't keeping under the direct sunlight.
b. Keeping in the tray under the dark place.
DON’T
DO
(1) Do not operate or store the LCD module under outside of specified environmental conditions.
(2) Be sure to prevent light striking the chip surface.
