1.7 Schematic
Diagram
The I2C communication interface consists of slave address bit DC, I2C-bus data signal SDA (SDAOUT/D2
for output and SDAIN/D1 for input) and I2C-bus clock signal SCL (D0). Both the data and clock signals must
be connected to pull-up resistors.
a) Slave address bit (SA0) has to recognize the slave address before transmitting or receiving any
information by the I2C-bus. The device will respond to the slave address following by the slave address bit
(“SA0” bit) and the read/write select bit (“R/W#” bit) with the following byte format,
b7 b6
0

b3 b2 b1 b0

b)“SA0” bit provides an extension bit for the slave address. Either “0111100” or “0111101”, can be
selected as the slave address of OLED. D/C# pin acts as SA0 for slave address selection.“R/W#” bit is used to
determine the operation mode of the I2C-bus interface. R/W#=1, it is in read mode. R/W#=0, it is in write
mode

Note 1: All the above voltages are on the basis of “GND = 0V”.
Note 2: When this module is used beyond the above absolute maximum ratings, permanent breakage
of the module may occur. Also, for normal operations, it is desirable to use this module under
the conditions according to Section 3. “Optics & Electrical Characteristics”. If this module is
used beyond these conditions, malfunctioning of the module can occur and the reliability of
the module may deteriorate.
Note 3: The defined temperature ranges do not include the polarizer. The maximum withstood
temperature of the polarizer should be 80C.
Note 4: VCC = 3.3 V, Ta = 25°C, 50% Checkerboard.
Software configuration follows Section 4.4 Initialization.
End of lifetime is specified as 50% of initial brightness reached. The average operating

7. Precautions When Using These OEL Display
Modules
7.1Handling Precautions
1)
2)
3)
4)
5)
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:
6)
* 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.
7)
8)
Do not apply stress to the driver IC and the surrounding molded sections.
Do not disassemble nor modify the OEL display module.
22
9) Do not apply input signals while the logic power is off.
10) 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.
7.2Storage 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 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 ZhongJingYuan technology Co.,Ltd.)
At that time, be careful not to let water drops adhere to the packages or bags nor let dewing occur with them.
2)
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.
7.3Designing Precautions
1)
2)
3)
4)
5)
6)
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.
23
7)
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.
8) The electric potential to be connected to the rear face of the IC chip should be as follows:
SSD1306
* Connection (contact) to any other potential than the above may lead to rupture of the IC.
7.4Precautions 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.
7.5Other Precautions
1)
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.
2) 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
3) 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.
4)
5)
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
statuses (re-setting of the commands and re-transference of the display data) to cope with
catastrophic noise.
24
