Precautions When Using These TFT Display Modules8.1Handling Precautions1)Since the display panel is being made of glass, do not apply mechanical impacts su

24、ch 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 TFT display module, the cell structure ma

25、y be damaged and be careful not to apply pressure to these sections.The polarizer covering the surface of the TFT display module is soft and easily scratched.Please be careful when handling the TFT display module.2)3)4)5)When the surface of the polarizer of the TFT display module has soil, clean the

26、 surface. advantage of by using following adhesion tape.* Scotch Mending Tape No. 810 or an equivalentIt takesNever 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 attent

27、ion that the following liquid and solvent may spoil the polarizer:* Water* Ketone* Aromatic SolventsHold TFT display module very carefully when placing TFT display module into the system housing. Do not apply excessive stress or pressure to TFT display module. And, do not over bend the film6)with el

28、ectrode pattern layouts.These stresses will influence the display performance.Also,secure sufficient rigidity for the outer cases.7)8)9)10)Do not apply stress to the driver IC and the surrounding molded sections. Do not disassemble nor modify the TFT display module.Do not apply input signals while t

29、he logic power is off.Pay sufficient attention to the working environments when handing TFT display modules to prevent occurrence of element breakage accidents by static electricity.* Be sure to make human body grounding when handling TFT display modules.* Be sure to ground tools to use or assembly

30、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 TFT display module. Be careful since static electricity may be generated when exfoliating the

31、protective film.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 TFT display module has been stored for a long period of time, residue adhesive material of the protection film may remain on the surface of

32、the display panel after removed of the film. uch case, remove the residue material by the method introduced in the above Section 5).If electric current is applied when the TFT display module is being dewed or when it is placed under high humidity environments, the electrodes may be corroded and be c

33、areful to avoid the above.11)12)深圳市力美拓科技Shenzhen Limito Technology Inc.8.2Storage Precautions1)When storing TFT display modules, put themtatic electricity preventive bags avoidingexposure to direct sun light nor to lights of fluorescent lamps. and, also, avoiding high temperatureand high humidity en

34、vironment or low temperature (less than 0 C) environments. (We recommend you to store these modules in the packaged state when they were shipped from Limito technology Inc.)At that time, be careful not to let water drops adhere to the packages or bags nor let dewing occur with them.If electric curre

35、nt is applied when water drops are adhering to the surface of the TFT display module, when the TFT 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.2)8.3Designing Precautions1)The absolute maximum ratin

36、gs are the ratings which cannot be exceeded for TFT 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 theandVILVIHspecifications and, at the same time, to make the signal line cable as short as po

37、ssible.3)We recommend you totall 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.As for EMI, take necessary measures on the equipment side basically

38、.When fastening the TFT display module, fasten the external plastic housing section.If power supply to the TFT display module is forcibly shut down by such errors as taking out the main battery while the TFT display panel is in operation, we cannot guarantee the quality of this OEL display module.Th

39、e electric potential to be connected to the rear face of the IC chip should be as follows:* Connection (contact) to any other potential than the above may lead to rupture of the IC.5)6)7)8)8.4Precautions when disposing of the TFT display modules1) Request the qualified companies to handle industrial

40、 wastes when disposing of the TFT display modules. Or, when burning them, be sure to observe the environmental and hygienic laws and regulations.Other Precautions8.51)When an TFT display module is operated for a long of time with fixed pattern may remain as an after image or slight contrast deviatio

41、n 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.To protect TFT display modules from performance drops by static electricity rapture, etc., do not touch the following se

42、ctions whenever possible while handling the TFT display modules.2)* Pand electrodes* Pattern layouts such as the FPCWith this TFT display module, the TFT driver is being exposed.3)Generally speaking,semiconductor elements change their characteristics when light is radiated according to theprinciple

43、of the solar battery.Consequently, if this TFT driver is exposed to light, malfunctioning may occur.* Design the product and actual usage.* Design the product andtallation method so that the TFT driver may be shielded from light intallation method so that the TFT driver may be shielded from lightdur

44、ing thepection processes.4)Although this TFT 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 maybe changed.It therefore is necessary to take appropriate measures to suppress noiseg

45、eneration or to protect from influences of noise on the system design.5)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.深圳市力美拓科技Shenzhen Limito Technology Inc.9.WWaarrrraannttyy:The warranty period shall last twelve (12) months from the date of delivery.Buyer shall be completed toassemble all the processes within the effective twelve (12) months.
