HANDLING PRECAUTIONS

(1) CAUTION OF LCD HANDLING & CLEANING

Use soft cloth with solvent (recommended below) to clean the display surface and wipe lightly.

- Isopropyl 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.
