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 hrs prior to conducting the failure test at 23±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** 1. The function test is OK. 2. No observable defects. 3. Luminance: > 50% of initial value. 4. 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.

(Resistors, capacitors and other passive components will have different appearance and color caused by the different supplier.) (11) Midas 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, Midas have the right to modify the version.) ## **1. 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 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. Page 16 of 17 - (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 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 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. ## **2. 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 Midas Displays. 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. ## **3. 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: 0.5A) - (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.
