◆ This device is susceptible to Electro-Static Discharge (ESD) damage. Observe Anti-Static precautions.
◆ EastRising display panel is made of glass. Do not subject it to a mechanical shock by dropping it or impact.
◆ If EastRising display panel is damaged and the liquid crystal substance leaks out, be sure not to get any in
your mouth. If the substance contacts your skin or clothes, wash it off using soap and water.
◆ Do not apply excessive force to the EastRising display surface or the adjoining areas since this may cause
the color tone to vary.
◆ The polarizer covering the EastRising display surface of the LCD module is soft and easily scratched.
Handle this polarizer carefully.
◆ If EastRising display surface becomes contaminated, breathe on the surface and gently wipe it with a soft
dry cloth. If it is heavily contaminated, moisten cloth with one of the following Isopropyl or alcohol.
◆ Solvents other than those above-mentioned may damage the polarizer. Especially, do not use the Water.
◆ Exercise care to minimize corrosion of the electrode. Corrosion of the electrodes is accelerated by water
droplets, moisture condensation or a current flow in a high-humidity environment.
◆ Install the EastRising LCD Module by using the mounting holes. When mounting the LCD module make
sure it is free of twisting, warping and distortion. In particular, do not forcibly pull or bend the cable or the
backlight cable.
◆ Do not attempt to disassemble or process EastRising LCD module.
◆ NC terminal should be open. Do not connect anything.
◆ If the logic circuit power is off, do not apply the input signals.
◆ To prevent destruction of the elements by static electricity, be careful to maintain an optimum work
environment.
-Be sure to ground the body when handling EastRising LCD modules.
-Tools required for assembling, such as soldering irons, must be properly grounded.
-To reduce the amount of static electricity generated, do not conduct assembling and other work under dry
conditions.
-The LCD module is coated with a film to protect the display surface. Exercise care when peeling off this
protective film since static electricity may be generated.

some variance between models.
◆ Prevent the application of reverse polarity to VDD and VSS, however briefly.
◆ Use a clean power source free from transients. Power-up conditions are occasionally jolting and may
exceed the maximum ratings of EastRising modules.
◆ The VDD power of EastRising module should also supply the power to all devices that may access the
display. Don’t allow the data bus to be driven when the logic supply to the module is turned off.

6.3 Operating Precautions
>>Return to CONTENTS
◆ DO NOT plug or unplug EastRising module when the system is powered up.
◆ Minimize the cable length between EastRising module and host MPU.
◆ For models with backlights, do not disable the backlight by interrupting the HV line. Unload inverters
produce voltage extremes that may arc within a cable or at the display.
◆ Operate EastRising module within the limits of the modules temperature specifications.
>>Return to CONTENTS
6.4 Mechanical/Environmental Precautions
◆ Improper soldering is the major cause of module difficulty. Use of flux cleaner is not recommended
as they may seep under the electrometric connection and cause display failure.
◆ Mount EastRising module so that it is free from torque and mechanical stress.
◆ Surface of the LCD panel should not be touched or scratched. The display front surface is an easily
scratched, plastic polarizer. Avoid contact and clean only when necessary with soft, absorbent cotton
dampened with petroleum benzene.
◆ Always employ anti-static procedure while handling EastRising module.
◆ Prevent moisture build-up upon the module and observe the environmental constraints for storage tem
◆ Do not store in direct sunlight
◆ If leakage of the liquid crystal material should occur, avoid contact with this material, particularly ingestion.
If the body or clothing becomes contaminated by the liquid crystal material, wash thoroughly with water and
soap
>>Return to CONTENTS
6.5 Storage Precautions
When storing the LCD modules, avoid exposure to direct sunlight or to the light of fluorescent lamps.
Keep EastRising modules in bags (avoid high temperature / high humidity and low temperatures below 0C
Whenever possible, EastRising LCD modules should be stored in the same conditions in which they were
shipped from our company.
>>Return to CONTENTS
6.6 Others
Liquid crystals solidify under low temperature (below the storage temperature range) leading to defective
orientation or the generation of air bubbles (black or white). Air bubbles may also be generated if the module

is subject to a low temperature.
If EastRising LCD modules have been operating for a long time showing the same display patterns, the
display patterns may remain on the screen as ghost images and a slight contrast irregularity may also
appear. A normal operating status can be regained by suspending use for some time. It should be noted that
this phenomenon does not adversely affect performance reliability.
To minimize the performance degradation of the LCD modules resulting from destruction caused by static
electricity etc., exercise care to avoid holding the following sections when handling the modules.
-Exposed area of the printed circuit board.
-Terminal electrode sections.

7. USING LCD MODULES
7.1 Liquid Crystal Display Modules
>>Return to CONTENTS
EastRising LCD is composed of glass and polarizer. Pay attention to the following items when handling.
◆ Please keep the temperature within specified range for use and storage. Polarization degradation, bubble
generation or polarizer peel-off may occur with high temperature and high humidity.
◆ Do not touch, push or rub the exposed polarizers with anything harder than an HB pencil lead (glass,
tweezers, etc.).
◆ N-hexane is recommended for cleaning the adhesives used to attach front/rear polarizers and reflectors
made of organic substances which will be damaged by chemicals such as acetone, toluene, ethanol and
isopropylalcohol.
◆ When EastRising display surface becomes dusty, wipe gently with absorbent cotton or other soft material
like chamois soaked in petroleum benzin. Do not scrub hard to avoid damaging the display surface.
◆ Wipe off saliva or water drops immediately, contact with water over a long period of time may cause
deformation or color fading.
◆ Avoid contacting oil and fats.
◆ Condensation on the surface and contact with terminals due to cold will damage, stain or dirty the polarizers.
After products are tested at low temperature they must be warmed up in a container before coming is
contacting with room temperature air.
◆ Do not put or attach anything on EastRising display area to avoid leaving marks on.
◆ Do not touch the display with bare hands. This will stain the display area and degradate insulation
between terminals (some cosmetics are determinated to the polarizers).
◆ As glass is fragile. It tends to become or chipped during handling especially on the edges. Please
avoid dropping or jarring.
7.2 Installing LCD Modules
>>Return to CONTENTS
◆ Cover the surface with a transparent protective plate to protect the polarizer and LC cell.
◆When assembling the LCM into other equipment, the spacer to the bit between the LCM and the fitting
plate should have enough height to avoid causing stress to the module surface, refer to the individual
specifications for measurements. The measurement tolerance should be±0.1mm.

7.3 Precaution for Handling LCD Modules
Since EastRising LCM has been assembled and adjusted with a high degree of precision; avoid applying
excessive shocks to the module or making any alterations or modifications to it.
◆ Do not alter, modify or change the shape of the tab on the metal frame.
◆ Do not make extra holes on the printed circuit board, modify its shape or change the positions of
components to be attached.
◆ Do not damage or modify the pattern writing on the printed circuit board.
◆ Absolutely do not modify the zebra rubber strip (conductive rubber) or heat seal connector.
◆ Except for soldering the interface, do not make any alterations or modifications with a soldering iron.
◆ Do not drop, bend or twist EastRising LCM.
>>Return to CONTENTS
7.4 Electro-Static Discharge Control
Since this module uses a CMOS LSI, the same careful attention should be paid to electrostatic discharge as
for an ordinary CMOS IC.
◆ Make certain that you are grounded when handing LCM.
◆ Before remove LCM from its packing case or incorporating it into a set, be sure the module and your body
have the same electric potential.
◆ When soldering the terminal of LCM, make certain the AC power source for the soldering iron does not leak.
◆ When using an electric screwdriver to attach LCM, the screwdriver should be of ground potentiality to
minimize as much as possible any transmission of electromagnetic waves produced sparks coming from the
commutator of the motor.
◆ As far as possible make the electric potential of your work clothes and that of the work bench the ground
potential.
◆ To reduce the generation of static electricity be careful that the air in the work is not too dried. A relative
humidity of 50%-60% is recommended.
>>Return to CONTENTS
7.5 Precaution for Soldering to EastRising LCM
◆ Observe the following when soldering lead wire, connector cable and etc. to the LCM.
-Soldering iron temperature : 280℃±10℃
-Soldering time: 3-4 sec.
-Solder: eutectic solder.
If soldering flux is used, be sure to remove any remaining flux after finishing to soldering operation. (This
does not apply in the case of a non-halogen type of flux.) It is recommended that you protect the LCD
surface with a cover during soldering to prevent any damage due to flux spatters.
◆ When soldering the electroluminescent panel and PC board, the panel and board should not be detached
more than three times. This maximum number is determined by the temperature and time conditions
mentioned above, though there may be some variance depending on the temperature of the soldering iron.
◆ When remove the electroluminescent panel from the PC board, be sure the solder has completely melted,
the soldered pad on the PC board could be damaged.

7.6 Precaution for Operation
◆ Viewing angle varies with the change of liquid crystal driving voltage (VO). Adjust VO to show the best
contrast.
◆ Driving the EastRising LCD in the voltage above the limit shortens its life.
◆ Response time is greatly delayed at temperature below the operating temperature range. However, this
does not mean the LCD will be out of the order. It will recover when it returns to the specified temperature
range.
◆ If EastRising display area is pushed hard during operation, the display will become abnormal. However, it
will return to normal if it is turned off and then back on.
◆ Condensation on terminals can cause an electrochemical reaction disrupting the terminal circuit. Therefore,
it must be used under the relative condition of 40℃, 50% RH.
◆ When turning the power on, input each signal after the positive/negative voltage becomes stable.
