9-4. Precautions for Strong Light Exposure
Strong light exposure causes degradation of polarizer and color filter.
9-5. Storage
When storing modules as spares for a long time, the following precautions are necessary.
(1) Store them in a dark place. Do not expose the module to sunlight or fluorescent light. Keep
the temperature between 5°C and 35°C at normal humidity.
(2) The polarizer surface should not come in contact with any other object. It is recommended
that they be stored in the container in which they were shipped.
(3) Storage condition is guaranteed under packing conditions.
(4) The phase transition of Liquid Crystal could be recovered if the LCM is released at the
normal condition after the low or over the storage temperature.
9-6. Handling Precautions for Protection Film
(1) The protection film is attached to the bezel with a small masking tape .
When the protection film is peeled off, static electricity is generated between the film and
polarizer. This should be peeled off slowly and carefully by people who are electrically
grounded and with well ionblown equipment or in such a condition, etc.
(2) When the module with protection film attached is stored for a long time, sometimes there
remains a very small amount of glue still on the bezel after the protection film is peeled off.
(3) You can remove the glue easily. When the glue remains on the bezel surface or its vestige
is recognized, please wipe them off with absorbent cotton waste or other soft material like
chamois soaked with normalhexane.
