4. Functional Specification
4.1 Commands
Refer to the Technical Manual for the SSD1325
4.2 Power down and Power up Sequence
To protect OEL panel and extend the panel life time, the driver IC power up/down routine should include
a delay period between high voltage and low voltage power sources during turn on/off. It gives the
OEL panel enough time to complete the action of charge and discharge before/after the operation.

Since the display panel is being made of glass, do not apply mechanical impacts such us dropping
from a high position.
If the display panel is broken by some accident and the internal organic substance leaks out, be
careful not to inhale nor lick the organic substance.
If pressure is applied to the display surface or its neighborhood of the OEL display module, the cell
structure may be damaged and be careful not to apply pressure to these sections.
The polarizer covering the surface of the OEL display module is soft and easily scratched. Please
be careful when handling the OEL display module.
When the surface of the polarizer of the OEL display module has soil, clean the surface. It takes
advantage of by using following adhesion tape.
* Scotch Mending Tape No. 810 or an equivalent
Never try to breathe upon the soiled surface nor wipe the surface using cloth containing solvent
such as ethyl alcohol, since the surface of the polarizer will become cloudy.
Also, pay attention that the following liquid and solvent may spoil the polarizer:
* Water
* Ketone
* Aromatic Solvents
Hold OEL display module very carefully when placing OEL display module into the system housing.
Do not apply excessive stress or pressure to OEL display module. And, do not over bend the film
with electrode pattern layouts. These stresses will influence the display performance. Also,
secure sufficient rigidity for the outer cases.

Do not apply stress to the driver IC and the surrounding molded sections.
Do not disassemble nor modify the OEL display module.
Do not apply input signals while the logic power is off.
Pay sufficient attention to the working environments when handing OEL display modules to prevent
occurrence of element breakage accidents by static electricity.
* Be sure to make human body grounding when handling OEL display modules.
* Be sure to ground tools to use or assembly such as soldering irons.
* To suppress generation of static electricity, avoid carrying out assembly work under dry
environments.
* Protective film is being applied to the surface of the display panel of the OEL display module.
Be careful since static electricity may be generated when exfoliating the protective film.
11) 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 OEL 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 removed of the film. In such case, remove the residue material by the method
introduced in the above Section 5).
12) If electric current is applied when the OEL display module is being dewed or when it is placed under
high humidity environments, the electrodes may be corroded and be careful to avoid the above.
8.2 Storage Precautions
1)
When storing OEL display modules, put them in static electricity preventive bags avoiding exposure
to direct sun light nor to lights of fluorescent lamps. and, also, avoiding high temperature and high
22
2)
humidity environment or low temperature (less than 0°C) environments. (We recommend you to
store these modules in the packaged state when they were shipped from WiseChip Semiconductor
Inc.)
At that time, be careful not to let water drops adhere to the packages or bags nor let dewing occur
with them.
If electric current is applied when water drops are adhering to the surface of the OEL display
module, when the OEL display module is being dewed or when it is placed under high humidity
environments, the electrodes may be corroded and be careful about the above.

The absolute maximum ratings are the ratings which cannot be exceeded for OEL display module,
and if these values are exceeded, panel damage may be happen.
To prevent occurrence of malfunctioning by noise, pay attention to satisfy the VIL and VIH
specifications and, at the same time, to make the signal line cable as short as possible.
We recommend you to install excess current preventive unit (fuses, etc.) to the power circuit (VDD).
(Recommend value: 0.5A)
Pay sufficient attention to avoid occurrence of mutual noise interference with the neighboring
devices.
As for EMI, take necessary measures on the equipment side basically.
When fastening the OEL display module, fasten the external plastic housing section.
If power supply to the OEL display module is forcibly shut down by such errors as taking out the
main battery while the OEL display panel is in operation, we cannot guarantee the quality of this
OEL display module.
The electric potential to be connected to the rear face of the IC chip should be as follows: SSD1325
* Connection (contact) to any other potential than the above may lead to rupture of the IC.
8.4 Precautions when disposing of the OEL display modules
1)
Request the qualified companies to handle industrial wastes when disposing of the OEL display
modules. Or, when burning them, be sure to observe the environmental and hygienic laws and
regulations.

When an OEL display module is operated for a long of time with fixed pattern may remain as an
after image or slight contrast deviation may occur.
Nonetheless, if the operation is interrupted and left unused for a while, normal state can be
restored. Also, there will be no problem in the reliability of the module.
To protect OEL display modules from performance drops by static electricity rapture, etc., do not
touch the following sections whenever possible while handling the OEL display modules.
* Pins and electrodes
* Pattern layouts such as the FPC
With this OEL display module, the OEL driver is being exposed.
Generally speaking,
semiconductor elements change their characteristics when light is radiated according to the
principle of the solar battery. Consequently, if this OEL driver is exposed to light, malfunctioning
may occur.
* Design the product and installation method so that the OEL driver may be shielded from light in
actual usage.
* Design the product and installation method so that the OEL driver may be shielded from light
during the inspection processes.
Although this OEL display module stores the operation state data by the commands and the
indication data, when excessive external noise, etc. enters into the module, the internal status may
be changed. It therefore is necessary to take appropriate measures to suppress noise generation
or to protect from influences of noise on the system design.
We recommend you to construct its software to make periodical refreshment of the operation
23
statuses (re-setting of the commands and re-transference of the display data) to cope with
catastrophic noise.
