Note
• Supply voltage for OLED system = operating voltage at 25 °C
TEST AND MEASUREMENT CONDITIONS
1. All measurements shall not be started until the specimens attain to temperature stability. After the completion of the
described reliability test, the samples were left at room temperature for 2 hours prior to conducting the failure test at
23 °C ± 5 °C, 55 % ± 15 % RH
2. All-pixels-on is used as operation test pattern
3. The degradation of polarizer are ignored for high temperature storage, high temperature / humidity storage, temperature
cycle
EVALUATION CRITERIA
4. The function test is OK
5. No observable defects
6. Luminance: > 50 % of initial value
7. Current consumption: within ± 50 % of initial value
APPENDIX: RESIDUE IMAGE
Because the pixels are lighted in different time, the luminance of active pixels may reduce or differ from inactive pixels.
Therefore, the residue image will occur. To avoid the residue image, every pixel needs to be lighted up uniformly.

PRECAUTIONS IN USE OF OLED MODULES
MODULES
1. Avoid applying excessive shocks to module or making any alterations or modifications to it
2. Do not make extra holes on the printed circuit board, modify its shape or change the components of OLED display module
3. Do not disassemble the OLED display module
4. Do not operate it above the absolute maximum rating
5. Do not drop, bend or twist OLED display module
6. Soldering: only to the I/O terminals
7. Storage: please storage in anti-static electricity container and clean environment
8. It is pretty common to use “screen saver” to extend the lifetime and do not use fix information for long time in real application
9. Do not use fixed information in OLED panel for long time, that will extend “screen burn” effect time
10. Vishay has the right to change the passive components, including R2 and R3 adjust resistors. (Resistors, capacitors, and
other passive components will have different appearance and color caused by the different supplier)
11. Vishay have the right to change the PCB Rev. (In order to satisfy the supplying stability, management optimization, and the
best product performance... etc, under the premise of not affecting the electrical characteristics and external dimensions,
Vishay have the right to modify the version)
HANDLING PRECAUTIONS
1. Since the display panel is being made of glass, do not apply mechanical impacts such us dropping from a high position
2. 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
3. If pressure is applied to the display surface or its neighborhood of the OLED display module, the cell structure may be
damaged and be careful not to apply pressure to these sections
4. The polarizer covering the surface of the OLED display module is soft and easily scratched. Please be careful when handling
the OLED display module
5. When the surface of the polarizer of the OLED 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
6. Hold OLED display module very carefully when placing OLED display module into the system housing. Do not apply
excessive stress or pressure to OLED 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. Do not apply stress to the LSI chips and the surrounding molded sections
8. Do not disassemble nor modify the OLED display module
9. Do not apply input signals while the logic power is off

10. Pay sufficient attention to the working environments when handing OLED display modules to prevent occurrence of element
breakage accidents by static electricity
• Be sure to make human body grounding when handling OLED 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 OLED 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 OLED 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 no. 5
12. If electric current is applied when the OLED 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
STORAGE PRECAUTIONS
1. When storing OLED 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
Vishay. 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 OLED display module, when the OLED
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
DESIGNING PRECAUTIONS
1. The absolute maximum ratings are the ratings which cannot be exceeded for OLED display module, and if these values are
exceeded, panel damage may be happen
2. 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
3. We recommend you to install excess current preventive unit (fuses, etc.) to the power circuit (VDD) (recommend value: 0.5 A)
4. Pay sufficient attention to avoid occurrence of mutual noise interference with the neighboring devices
5. As for EMI, take necessary measures on the equipment side basically
6. When fastening the OLED display module, fasten the external plastic housing section
7. If power supply to the OLED display module is forcibly shut down by such errors as taking out the main battery while the
OLED display panel is in operation, we cannot guarantee the quality of this OLED display module
• Connection (contact) to any other potential than the above may lead to rupture of the IC
PRECAUTIONS WHEN DISPOSING OF THE OLED DISPLAY MODULES
1. Request the qualified companies to handle industrial wastes when disposing of the OLED display modules. Or, when burning
them, be sure to observe the environmental and hygienic laws and regulations
OTHER PRECAUTIONS
1. When an OLED 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 OLED display modules from performance drops by static electricity rapture, etc., do not touch the following
sections whenever possible while handling the OLED display modules
• Pins and electrodes
• Pattern layouts such as the TCP and FPC
3. With this OLED display module, the OLED 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 OLED driver
is exposed to light, malfunctioning may occur
• Design the product and installation method so that the OLED driver may be shielded from light in actual usage
• Design the product and installation method so that the OLED driver may be shielded from light during the inspection
processes
