Crystalfontzwww.crystalfontz.comCFAL12836A0-088 OLED Display ModuleDatasheet Release Date 2017-08-1112. OLED Module PrecautionsThe precautions below should be followed when using OLED modules to help ensure personal safety,module performance, and compliance of environmental regulations.12.1. Modules Avoid applying excessive shocks to module or making any alterations or modifications to it. Do not make extra holes on the printed circuit board, modify its shape or change thecomponents of OLED display module. Do not disassemble the OLED display module. Do not operate the OLED display module above the absolute maximum rating. Do not drop, bend or twist the OLED display module. Soldering: only to the I/O terminals. Store in an anti-static electricity container and clean environment. It is common to use the "screen saver" to extend the lifetime of the OLED display module.o Do not use the fixed information for long periods of time in real application.o Do not use fixed information in OLED panel for long periods of time to extend "screenburn" effect time. Crystalfontz has the right to change the passive components, including R2 and R3 adjustresistors. (Resistors, capacitors and other passive components will have different appearanceand color caused by the different supplier.) Crystalfontz 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 notaffecting the electrical characteristics and external dimensions, Crystalfontz has the right tomodify the version.).12.2. Handling Precautions Since the display panel is made of glass, do not apply mechanical impacts such as droppingfrom a high position. If the display panel is accidently broken, and the internal organic substance leaks out, becareful not to inhale or touch the organic substance. If pressure is applied to the display surface or its neighborhood of the OLED display module,the cell structure may be damaged, so be careful not to apply pressure to these sections. The polarizer covering the surface of the OLED display module is soft and can be easilyscratched. Please be careful when handling the OLED display module. Clean the surface of the polarizer covering the OLED display module if it becomes soiled usingfollowing adhesion tape.o Scotch Mending Tape No. 810 or an equivalento Never breathe the soiled surface or wipe the surface using a cloth containing solventsuch as ethyl alcohol, since the surface of the polarizer will become cloudy.o The following liquids/solvents may spoil the polarizer:-WaterKetoneAromatic Solvents Hold the OLED display module very carefully when placing the OLED display module into thesystem housing. Do not apply excessive stress or pressure to the OLED display module. And, do not over bendthe film with electrode pattern layouts. These stresses will influence the display performance.Also, be sure to secure the sufficient rigidity for the outer cases.Page 9

Crystalfontzwww.crystalfontz.comCFAL12836A0-088 OLED Display ModuleDatasheet Release Date 2017-08-11 Do not apply stress to the LSI chips and the surrounding molded sections.Do not disassemble or modify the OLED display module.Do not apply input signals while the logic power is off.Pay sufficient attention to the working environments when handing the OLED display moduleto prevent occurrence of element breakage accidents by static electricity.o Be sure to make human body grounding when handling OLED 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 dryenvironments.o Protective film is being applied to the surface of the display panel of the OLED displaymodule. Be careful since static electricity may be generated when exfoliating theprotective film. Protection film is being applied to the surface of the display panel and removes the protectionfilm before assembling it. At this time, if the OLED display module has been stored for a longperiod of time, residue adhesive material of the protection film may remain on the surface ofthe display panel after the film has been removed. In such a case, remove the residue materialby the method discussed above. If electric current is applied when the OLED display module is being dewed or when it is placedunder high humidity environments, the electrodes may become corroded. If this happensproceed with caution when handling the OLED display module.12.3. Storage Precautions When storing the OLED display modules put them in static electricity preventive bags to avoidexposure to direct sunlight and fluorescent lamps. Also avoid high temperature and highhumidity environments and low temperatures (less than 0 C) environments. (We recommendyou store these modules in the packaged state when they were shipped from Crystalfontz). Becareful not to let water drops adhere to the packages or bags, and do not let dew gather onthem. If electric current is applied when water drops are adhering to the surface of the OLED displaymodule the OLED display module may have become dewed. If a dewed OLED display moduleis placed under high humidity environments it may cause the electrodes to become corroded. Ifthis happens proceed with caution when handling the OLED display module.12.4. Designing Precautions The absolute maximum ratings are the ratings that cannot be exceeded for OLED displaymodule. If these values are exceeded, panel damage may happen. To prevent occurrence of malfunctioning by noise pay attention to satisfy the VIL and VIHspecifications 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(VDD). (Recommend value: 0.5A) Pay sufficient attention to avoid occurrence of mutual noise interference with the neighboringdevices. As for EMI, take necessary measures on the equipment side. When fastening the OLED display module, fasten the external plastic housing section. If the power supply to the OLED display module is forcibly shut down, by such errors as takingout the main battery while the OLED display panel is in operation, we cannot guarantee thequality of this OLED 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 OLEDdisplay modules. Or, when burning them, be sure to observe the environmental and hygieniclaws and regulations.12.6. Other Precautions When an OLED display module is operated for a long period of time with a fixed pattern, thefixed pattern may remain as an after image or a slight contrast deviation may occur.o If the operation is interrupted and left unused for a while, normal state can be restored.o This will not cause a problem in the reliability of the module.Page 10

Crystalfontzwww.crystalfontz.comCFAL12836A0-088 OLED Display ModuleDatasheet Release Date 2017-08-11 To protect the OLED display module from performance drops by static electricity rapture, etc.,do not touch the following sections whenever possible while handling the OLED displaymodules.o Pins and electrodeso Pattern layouts such as the TCP & FPC With this OLED display module, the OLED driver is being exposed. Generally speaking,semiconductor elements change their characteristics when light is radiated according to theprinciple of the solar battery. Consequently, if this OLED driver is exposed to light,malfunctioning may occur.o Design the product and installation method so that the OLED driver may be shielded fromlight in actual usage.o Design the product and installation method so that the OLED driver may be shielded fromlight during the inspection processes. Although this OLED display module stores the operation state data by the commands and theindication data, when excessive external noise, etc. enters into the module, the internal statusmay be changed. Therefore, it is necessary to take appropriate measures to suppress noisegeneration or to protect from influences of noise on the system design. We recommend that you construct its software to make periodical refreshment of the operationstatuses (re-setting of the commands and re-transference of the display data), to cope withcatastrophic noise. Resistors, capacitors, and other passive components will have different appearance and colorcaused by the different supplier. Crystalfontz has the right to upgrade and modify the product function.
