6.PRECAUTIONSFORUSING
6.1 Handling Precautions
◆ 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.

338B335B332B42B461B458B455B339B336B333B◆ Identify and, at all times, observe absolute maximum ratings for both logic and LC drivers. Note that there is 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
345B342B339B◆ 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.
349B346B343B44B452B449B446B6.4 Mechanical/Environmental Precautions
350B347B344B◆ 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.
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 0 ºC.

6.6 Others
363B360B357BLiquid 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.

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 isopropyl alcohol.
◆ 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.

7.2 Installing LCD Modules
384B381B378B42B447B444B441B385B382B379B◆ 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.
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.
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 PCs board could be damaged.
7.6 Precaution for Operation
413B410B407B◆ 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.

8.IMAGESTICKING HHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHH HHH
369B366B363B31B450B447B444B8.1 What is Image Sticking?
If you remain a fixed image on LCD Display for a long period of time, you may experience a phenomenon called Image
Sticking. Image Sticking - sometimes also called “image retention” or “ghosting”- is a phenomenon where a faint
outline of a previously displayed image remains visible on the screen when the image is changed. It can occur at
variable levels of intensity depending on the specific image makeup, as well as the amount of time the core image
elements are allowed to remain unchanged on the screen. In POS applications, for example, a button menu which
remains fixed, or in which the “frame” elements (core image) remain fixed and the buttons may change, may be
susceptible to image sticking. It is important to note that if the screen is used exclusively for this application, the user
may never notice this phenomenon since the screen never displays other content. `It is only when an image other than
the “retained” image is shown on the screen that this issue becomes evident. Image sticking is different that the
“burn-in” effect commonly associated with phosphor based devices.
8.2 What causes Image Sticking?
Image sticking is an intrinsic behavior of LCD displays due to the susceptibility to polarization of the interior materials
(liquid crystals) when used under static, charged conditions (continuously displaying the same image). The individual
liquid crystals in an LCD panel have unique electrical properties. Displaying a fixed pattern - such as the POS menu
described above – over prolonged periods can cause a parasitic charge build-up (polarization) within the liquid
crystals which affects the crystals’ optical properties and ultimately prevents the liquid crystal from returning to its
normal, relaxed state when the pattern is finally changed. This effect takes place at a cellular level within the LCD, and
the effect can cause charged crystal alignment at the bottom or top of a crystal cell in the “z” axis, or even crystal
migration to the edges of a cell, again based on their polarity. These conditions can cause image sticking over an
entire area, or at boundaries of distinct color change respectively. In either case, when the liquid crystals in the pixels
and sub-pixels utilized to display the static image are polarized such that they can not return fully to their “relaxed”
state upon deactivation, the result is a faint, visible, retained image on the panel upon presentation of a new, different
image. The actual rate of image retention depends on variation factors such as the specific image, how long it is
displayed unchanged, the temperature within the panel and even the specific panel brand due to manufacturing
differences amongst panel manufacturers.

8.3 How to Avoid Image Sticking?
- Try not to operate the LCD with a “fixed” image on the screen for more than 2 hours.
- If you are operating the monitor in an elevated temperature environment and with a displayed image which is
contrary to the recommendations in “For Software Developers” below, image stick can occur in as little as 30
minutes. Adjust your screen saver settings accordingly.
- Power down the unit during prolonged periods of inactivity such as the hours a store is closed or a shift during which
the piece of equipment isn’t used.
- Use a screensaver with a black or medium gray background that is automatically set to come on if the device is
inactive for more than 5-10 minutes.
- Avoid placing the monitor in poorly ventilated areas or in areas that will create excess heat around the monitor for
software developers.
- In defining the icons, buttons, or windows in the screen, try to utilize block patterns instead of distinct lines as
borders for dividing the display into distinct areas.
- If it is necessary to display a static image, try to use colors that are symmetric to the middle grey level at the
boundary of two different colors, and slightly shift the borders line once in a while.
- Try to utilize medium gray hues for those areas that will have prolonged display times or remain static as other menu
elements change.
8.4 How to Fix the Image Sticking?
Unlike the usually irreversible “burn-in” effects commonly associated with direct view phosphor display devices
such as CRTs, an image retained on an LCD display can be reversed – often to a point of total invisibility. However, the
severity of the underlying causes (as described above) of the image retained on a specific display, as well as the
variation factors (see “For Software Developers” above) under which the retained image was created, will dictate the
final level of retention reversal. One way to erase a retained image on a panel is to run the screen (monitor “on”) in
an “all black” pattern for 4-6 hours. It is also helpful to do this in an elevated temperature environment of
approximately 35º to 50ºC. Again, utilizing a dynamic screen saver with an all black background during prolonged idle
display periods is a good way to avoid image retention issues.
8.5 Is Image Sticking Covered by EastRising RMA Warranty?
Image sticking is a phenomenon inherent to LCD display technology itself, and as such, the occurrence of this
“ghosting” effect is considered normal operation by the manufacturers of the LCD display modules which are
integrated into today’s monitor solutions. EastRising does not warrant any display against the occurrence of image
sticking. We strongly advise that you follow the operating recommendations listed above to avoid the occurrence of
this phenomenon.
