11.1 MOUNTING METHOD

(1) USE OF PROTECTIVE PLATE, MADE OF AN ACRYLIC PLATE, ETC, IN
ORDER TO PROTECT A POLARIZER AND LC CELL.
(2) TO PREVENT THE MODULE COVER FROM BEING PRESSED, THE
SPACERS BETWEEN THE MODULE AND THE FITTING PLATES SHOUD
BE LONGER THAN 0.5mm.
(3) WE RECOMMEND YOU TO USE PROTECTIVE SPACER AS FIGURE FOR
PROTECTING LCD MODULE FROM ANY KIND OF SHOCK TO YOUR SET.

SETTING VEE OUT OF THE RECOMMENDED CONDITION WILL BE A

11.3 CAUTION AGAINST STATIC CHARGE
AS THIS MODULE IS PROVIDED WITH C-MOS LSI, THE CARE TO TAKE
SUCH A PRECAUTION AS TO GROUNDING THE OPERATOR’S BODY IS
REQUIRED WHEN HANDLING IT.

11.4 POWER ON SEQUENCE
INPUT SIGNALS SHOULD NOT BE APPLIED TO LCD MODULE BEFORE
POWER SUPPLY VOLTAGE IS APPLIED AND REACHES TO SPECIFIED
VOLTAGE (5+/-0.25V) IF ABOVE SEQUENCE IS NOT KEPT, C-MOS LSI OF
LCD MODULES MAY BE DAMAGED DUE TO LATCH UP PROBLEM.

11.5 PACKAGING
(1) NO. LEAVING PRODUCTS IS PREFERABLE IN THE PLACE OF HIGH
HUMIDITY FOR A LONG PERIOD OF TIME. FOR THEIR STORAGE IN
THE PLACE WHERE TEMPERATURE IS 35°C OR HIGHER, SPECIAL CARE
TO PREVENT THEM FROM HIGH HUMIDITY IS REQUIRED. A COMBINATION
OF HIGH TEMPERATURE AND HIGH HUMIDITY MAY CAUSE THEM
POLARIZATION DEGRADATION AS WELL AS BUBBLE GENERATION AND
POLARIZER PEEL-OFF. PLEASE KEEP THE TEMPERATURE AND HUMIDITY
WITHIN THE SPECIFIED RANGE FOR USE AND STORING.
(2) SINCE UPPER POLARIZERS AND LOWER ALUMINUM PLATES TEND TO BE
EASILY DAMAGED, THEY SHOULD BE HANDLED WITH FULL CARE SO AS
NOT TO GET THEM TOUCHED, PUSHED OR RUBBED BY A PIECE OF
GLASS. TWEEZERS AND ANYTHING ELSE WHICH ARE HARDER THAN A
PENCIL LEAD 3H.
(3) AS THE ADHESIVES USED FOR ADHERING UPPER/LOWER POLARIZES AND
ALUMINUM PLATES ARE MADE OF ORGANIC SUBSTANCES WHICH WILL
BE DETERIORATED BY A CHEMICAL REACTION WITH SUCH CHEMICALS
AS ACETONE, TULUENE ETHANOLE AND ISOPROPYLALCOHIL. THE
FOLLOWING SOLVENTS ARE RECOMMENDED FOR USE:
NORMAL HEXANE
PLEASE CONTACT US WHEN IT IS NECESSARY FOR YOU TO USE
CHEMICALS OTHER THAN THE ABOVE.
(4) LIGHTLY WIPE TO CLEAN THE DIRTY SURFACE WITH ABSORBENT
COTTON WASTE OR OTHER SOFT MATERIAL LIKE CHAMOIS, SOAKED IN
THE CHEMICALS RECOMMENDED WITHOUT SCRUBBING IT HARDLY.
TO PREVENT THE DISPLAY SURFACE FROM DAMAGE AND KEEP THE
APPEARANCE IN GOOD STATE, IT IS SUFFICIENT, IN GENERAL, TO WIPE
IT WITH ABSORBENT COTTON.

No.

(5) IMMEDIATELY WIPE OFF SALIVA OFF SALIVA OR WATER DROP
ATTACHED ON THE DISPLAY AREA BECAUSE ITS LONG PERIOD
ADHERENCE MAY CAUSE DEFORMATION OR FADED COLOR ON THE
SPOT.
(6) FOGY DEW DEPOSITED ON THE SURFACE AND CONTACT TERMINALS
DUE TO COLDNESS WILL BE CAUSE FOR POLARIZER DAMAGE,
STAIN AND DIRT ON PRODUCT. WHEN NECESSARY TO TAKE OUT
THE PRODUCTS FROM SOME PLACE AT LOW TEMPERATURE FOR
TEST, ETC. IT IS REQUIRED THEM TO BE WARMED UP IN A
CONTAINER ONCE AT THE TEMPERATURE HIGHER THAN THAT OF
ROOM.
(7) TOUCHING THE DISPLAY AREA AND CONTACT TERMINALS WITH
BARE HANDS AND CONTAMINATING THEM ARE PROHIBITED, BECAUSE
THE STAIN ON THE DISPLAY AREA AND POOR INSULATION BETWEEN
TERMINALS ARE OFTEN CAUSED BY BEING TOUCHED BY BARE HANDS.
(THERE ARE SOME COSMETICS DETRIMENTAL TO POLARIZERS.)
(8) IN GENERAL THE QUALITY OF GLASS IS FRAGILE SO THAT IT
TENDS TO BE CRACKED OR CHIPPED IN HANDLING,SPECIALLY ON
ITS PERIPHERY DOWN, ECT.

11.6 CAUTION FOR OPERATION
(1) IT IS AN INDISPENSABLE CONDITION TO DRIVE LCD‘S WITHIN THE
SPECIFIED VOLTAGE LIMIT SINCE THE HIGHER VOLTAGE THAN THE
