11. precautions in use of oled modules-1 modules (1)avoid applying excessive shocks to module or mak ing any alterations or modifications to it. (2)dont make extra holes on the printed circuit bo ard, modify its shape or change the components of oled module. (3)dont disassemble the oledm. (4)dont operate it above the absolute maximum rati ng. (5)dont drop, bend or twist oledm. (6)soldering: only to the i/o terminals. (7)storage: please storage in anti-static electrici ty container and clean environment. 17.1 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 substanc e. (3) if pressure is applied to the display surface o r 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 mo dule. (5) when the surface of the polarizer of the oled d isplay 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 wi pe the surface using cloth containing solvent such as ethyl alcohol, since the surface of the pol arizer will become cloudy. also, pay attention that the following liquid and s olvent may spoil the polarizer: * water * ketone * aromatic solvents (6) hold oled display module very carefully when pl acing oled display module into the system housing. do not apply excessive stress or pr essure to oled display module. and, do not over bend the film with electrode pattern layou ts. these stresses will influence the display performan ce. also, secure sufficient rigidity for the outer cases. free datasheet http:///
(7) do not apply stress to the lsi chips and the su rrounding molded sections. (8) do not disassemble nor modify the oled display module. (9) do not apply input signals while the logic powe r is off. (10) pay sufficient attention to the working enviro nments when handing oled display modules to prevent occurrence of element breakage a ccidents by static electricity. * be sure to make human body grounding when handlin g oled display modules. * be sure to ground tools to use or assembly such a s soldering irons. * to suppress generation of static electricity, avo id carrying out assembly work under dry environments. * protective film is being applied to the surface o f 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 surfac e 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 materia l of the protection film may remain on the surface of the display panel after removed of the f ilm. in such case, remove the residue material by the method introduced in the above sect ion 5. (12) if electric current is applied when the oled d isplay module is being dewed or when it is placed under high humidity environments, the electr odes may be corroded and be careful to avoid the above. 8.2 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 l ow temperature (less than 0c) environments. (we recommend you to store these modules in the pac kaged state when they were shipped from winstar technology inc. at that time, be careful not to let water drops adh ere 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 bei ng dewed or when it is placed under high humidity environments, the electrodes may be c orroded and be careful about the above. 8.3 designing precautions (1) the absolute maximum ratings are the ratings wh ich cannot be exceeded for oled display module, and if these values are exceeded, p anel damage may be happen. (2) to prevent occurrence of malfunctioning by nois e, pay attention to satisfy the vil and vih specifications and, at the same time, to make the s ignal line cable as short as possible. (3) we recommend you to install excess current prev entive 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 equi pment 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 f orcibly shut down by such errors as taking out the main battery while the oled display panel i s 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. free datasheet http:///
8.4 precautions when disposing of the oled display modules 1) request the qualified companies to handle indust rial wastes when disposing of the oled display modules. or, when burning them, be sure to observe the environmental and hygienic laws and regulations. 8.5 other precautions (1) when an oled display module is operated for a l ong of time with fixed pattern may remain as an after image or slight contrast deviation may occ ur. nonetheless, if the operation is interrupted and le ft unused for a while, normal state can be restored. also, there will be no problem in the rel iability of the module. (2) to protect oled display modules from performanc e 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 & 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 th is oled driver is exposed to light, malfunctioning may occur. * design the product and installation method so tha t the oled driver may be shielded from light in actual usage. * design the product and installation method so tha t the oled driver may be shielded from light during the inspection processes. (4) although this oled display module stores the op eration 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 a ppropriate measures to suppress noise generation or to protect from influences of noise o n the system design. (5) we recommend you to construct its software to m ake periodical refreshment of the operation statuses (re-setting of the commands and re-transfe rence of the display data) to cope with catastrophic noise. (6)resistors,capacitors and other passive component s will have different appearance and color caused by the different supplier. (7)our company will has the right to upgrade and mo dify the product function. free datasheet http:///
