12.0 HANDLING & CAUTIONS
12.1 Cautions when taking out the module
Pick the pouch only, when taking out module from a shipping package.
12.2 Cautions for handling the module
As the electrostatic discharges may break the LCD module, handle the LCD module with care.
Peel a protection sheet off from the LCD panel surface as slowly as possible.
As the LCD panel and backlight element are made from fragile glass material, impulse and
pressure to the LCD module should be avoided.
As the surface of the polarizer is very soft and easily scratched, use a soft dry cloth without
chemicals for cleaning.
Do not pull the interface connector in or out while the LCD module is operating.
Put the module display side down on a flat horizontal plane.
Handle connectors and cables with care.
12.3 Cautions for the operation
When the module is operating, do not lose MCLK, DE signals. If any one of these signals
were lost, the LCD panel would be damaged.
Obey the supply voltage sequence. If wrong sequence were applied, the module would be
damaged.
12.4 Cautions for the atmosphere
Dewdrop atmosphere should be avoided.
Do not store and/or operate the LCD module in a high temperature and/or humidity
atmosphere. Storage in an electro-conductive polymer-packing pouch and under relatively low
temperature atmosphere is recommended.
12.5 Cautions for the module characteristics
Do not apply fixed pattern data signal to the LCD module at product aging.
Applying fixed pattern for a long time may cause image sticking.
12.6 Other cautions
Do not disassemble and/or re-assemble LCD module.
Do not re-adjust variable resistor or switch etc.
When returning the module for repair or etc, please pack the module not to be broken. We
recommend using the original shipping packages.
