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. 

 

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 ion- blown 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 thebezel surface 

or its vestige is recognized, please wipe them off with absorbent cotton waste 
or other soft material like chamois soaked with normal- hexane.
