6. NOTES
Safety
If the LCD panel breaks, be careful not to get the liquid crystal in your
mouth. If the liquid crystal touches your skin or clothes, wash it off
immediately using soap and plenty of water.
Handling
Avoid static electricity as this can damage the CMOS LSI.
The LCD panel is plate glass; do not hit or crush it.
Do not remove the panel or frame from the module.
The polarizing plate of the display is very fragile; handle it very carefully
Mounting and Design
Mount the module by using the specified mounting part and holes.
To protect the module from external pressure, leave a small gap by placing
transparent plates (e.g. acrylic or glass ) on the display surface, frame, and
polarizing plate
Design the system so that no input signal is given unless the power-supply
voltage is applied.
Keep the module dry. Avoid condensation, otherwise the transparent
electrodes may break.
Storage
Store the module in a dark place where the temperature is 25 oC±10 oC and
the humidity below 65% RH.
Do not store the module near organic solvents or corrosive gases.
Do not crush, shake, or jolt the module (including accessories).
Cleaning
Do not wipe the polarizing plate with a dry cloth, as it may scratch the
surface.
Wipe the module gently with soft cloth soaked with a petroleum benzine.
Do not use ketonic solvents (ketone and acetoe) or aromatic solvents
(toluene and xylene), as they may damage the polarizing plate.
7. OPERATION PRECAUTIONS
Any changes that need to be made in this specification or any problems arising
from it will be dealt with quickly by discussion between both companies.
