Precautions When Using These TFT Display Modules
Handling Precautions
- Since the display panel is being made of glass, do not apply mechanical impacts such 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 may 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.
- When the surface of the polarizer of the TFT 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
- Scotch Mending Tape No. 810 or an equivalent
- Hold 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 film with electrode pattern layouts. These stresses will influence the display performance. Also, secure sufficient rigidity for the outer cases.
- 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 the 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 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 protective film.
- The 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, the 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 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 careful to avoid the above
Storage Precautions
- When storing TFT 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 environments 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 current 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.
Designing Precautions
- The absolute maximum ratings are the ratings that cannot be exceeded for TFT display module, and if these values are exceeded, panel damage may be happen.
- To prevent the 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.
- We recommend you to install an excess current preventive unit (fuses, etc.) to the power circuit (VDD). (Recommend value: 0.5A)
- Pay sufficient attention to avoid the occurrence of mutual noise interference with the neighboring devices.
- As for EMI, take necessary measures on the equipment side basically.
- When fastening the TFT display module, fasten the external plastic housing section.
- If the 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.
- The 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.
Precautions when disposing of the TFT display modules
Request qualified companies to handle industrial wastes when disposing of the TFT display modules. Or, when burning them, be sure to observe the environmental and hygienic laws and regulations.
Other Precautions
- When an TFT 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.
- To protect TFT display modules from performance drops by static electricity rapture, etc., do not touch the following sections whenever possible while handling the TFT display modules.
- Pins and electrodes
- Pattern layouts such as the FPC
- With this TFT display module, the TFT 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 TFT driver is exposed to light, malfunctioning may occur.
- Design the product and installation method so that the TFT driver may be shielded from light in actual usage.
- Design the product and installation method so that the TFT driver may be shielded from light during the inspection processes.
- 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 may be changed. It therefore is necessary to take appropriate measures to suppress noise generation or to protect from influences of noise on the system design.
- 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.
Warranty
