HANDLING PRECAUTIONS
(1) CAUTION OF LCD HANDLING & CLEANING
Use soft cloth with solvent (recommended below) to clean the display surface and wipe lightly.
- Isopropy l alcohol, ethyl alcohol, trichlorotriflorothane
Do not wipe the display surface with dry or hard materials that will damage the polarizer surface. Do not use
the following solvent;
-water, ketone, aromatics
(2) CAUTION AGAINST STATIC CHARGE
The LCD modules use CMOS LSI drivers, so customers are recommend that any unused input terminal
would be connected to VDD or VSS , do not input any signals before power is turned on, and ground your
body, work/assembly areas, assembly equipment to protect against static electricity.
Remove the protective film slowly and, if possible, under ESD control device like ion blower and humidity
of working room should be kept over 50%RH to reduce risk of static charge.
(3) PACKAGING
Avoid intense shock and falls from a height and do not operate or store them exposed direct to sunshine or
high temperature/humidity.
(4) CAUTION FOR OPERATION
It is an indispensable condition to drive LCD’s within the specified voltage limit since the higher voltage
than the limit causes the shorter LCD life. The use of direct current drive should be avoided because an
electrochemical reaction due to direct current causes LCD’s undesirable deterioration.
Response time will be extremely delayed at low temperature, and LCD’s show dark color at high
temperature. However those phenomena do not mean malfunction or out of order with LCD’s.
Some font will be abnormally displayed when the display area is pushed hard during operation. But it
resumes normal condition after turning off once.
(5) SOLDERING (for Pin type)
It is recommended to complete dip soldering at 270 oC or hand soldering at 280 oC within 3 seconds. The
soldering position is at least 3mm apart from the pin head. Wave or reflow soldering are not recommended.
Metal pins should not be soldered for more than 3 times and each soldering should be done after cool down
of metal pins
(6) SAFETY
For crash damaged or unnecessary LCD’s, it is recommended to wash off liquid crystal by either of solvents
such as acetone and ethanol and should be burned up later.
When any liquid leaked out of a damaged glass cell comes in contact with your hands, wash it off with soap
and water.
WARRANTY
CLOVER will replace or repair any of her LCD module in accordance with her LCD specification for a period
of one year from date of shipment. The warranty liability of Clover is limited to repair and/or replacement.
Clover will not be responsible for any subsequent or consequential event.
