•

Do not apply stress to the LSI chips and the surrounding molded sections.

•

Do not disassemble or modify the LCD display module.

•

Do not apply input signals while the logic power is off.

•

Pay sufficient attention to the working environments when handing the LCD display module to

prevent occurrence of element breakage accidents by static electricity.

o

Be sure to make human body grounding when handling LCD display modules.

o

Be sure to ground tools to use for assembly such as soldering irons.

o

To suppress generation of static electricity, avoid carrying out assembly work

under dry environments.

o

Protective film is being applied to the surface of the display panel of the LCD

display module. Be careful since static electricity may be generated when

exfoliating the protective film.

•

Protection film is being applied to the surface of the display panel and removes the protection

film before assembling it. At this time, if the LCD display module has been stored for a long

period of time, residue adhesive material of the protection film may remain on the surface of

the display panel after the film has been removed. In such a case, remove the residue

material by the method discussed above.

•

If electric current is applied when the LCD display module is being dewed or when it is placed

under high humidity environments, the electrodes may become corroded. If this happens

proceed with caution when handling the LCD display module.

12.3. Storage Precautions

•

When storing the LCD display modules put them in static electricity preventive bags to avoid

exposure to direct sunlight and fluorescent lamps. Also avoid high temperature and high

humidity environments and low temperatures (less than 0°C) environments. (We recommend

you store these modules in the packaged state when they were shipped from Crystalfontz).

Be careful not to let water drops adhere to the packages or bags, and do not let dew gather

on them.

•

If electric current is applied when water drops are adhering to the surface of the LCD display

module the LCD display module may have become dewed. If a dewed LCD display module is

placed under high humidity environments it may cause the electrodes to become corroded. If

this happens proceed with caution when handling the LCD display module.

12.4. Designing Precautions

•

The absolute maximum ratings are the ratings that cannot be exceeded for LCD display

module. If these values are exceeded, panel damage may happen.

•

specifications and, at the same time, to make the signal line cable as short as possible.

•

We recommend that you install excess current preventive unit (fuses, etc.) to the power circuit

•

Pay sufficient attention to avoid occurrence of mutual noise interference with the neighboring

devices.

•

As for EMI, take necessary measures on the equipment side.

•

When fastening the LCD display module, fasten the external plastic housing section.

•

If the power supply to the LCD display module is forcibly shut down, by such errors as taking

out the main battery while the LCD display panel is in operation, we cannot guarantee the

quality of this LCD display module.

o

Connection (contact) to any other potential than the above may lead to rupture of

the IC.

12.5. Disposing Precautions

•

Request the qualified companies to handle the industrial wastes when disposing of the LCD

display modules. Or, when burning them, be sure to observe the environmental and hygienic

laws and regulations.

12.6. Other Precautions

•

When an LCD display module is operated for a long period of time with a fixed pattern, the

fixed pattern may remain as an after image or a slight contrast deviation may occur.
