1. 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 When fixed patterns are displayed for a long time remnant image is likely to occur Module has high frequency circuits Sufficient suppression to the electromagnetic interference shall be done by system manufacturers Grounding and shielding methods may be important to minimized the interference Electrostatic Discharge Control Since a module is composed of electronic circuits it is not strong to electrostatic discharge Make certain that treatment persons are connected to ground through wrist band etc And don t touch interface pin directly Strong Light Exposure Strong light exposure causes degradation of polarizer and color filter Storage When storing modules as spares for a long time the following precautions are necessary 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 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 Protection Film 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
