(4) Be careful for condensation at sudden temperature change. Condensation 

makes damage to polarizer or electrical contacted parts. And after fading 

condensation, smear or spot will occur. 

(5) When fixed patterns are displayed for a long time, remnant image is likely 

to occur. 

(6) Module has high frequency circuits. System manufacturers shall do 

sufficient suppression to the electromagnetic interference. Grounding and 

shielding methods may be important to minimize the interference. 

 

2. Handling Precautions For Protection   

(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 the bezel 

surface or its vestige is recognized, please wipe them off with absorbent 

cotton waste or other soft material like chamois soaked with 

normal-hexane.
