11.1 MOUNTING METHOD
SINCE THE MODULE IS SO CONSTRUCTED AS TO BE FIXED BY UTILIZING
FITTING HOLES IN THE MODULE AS SHOWN BELOW, IT IS NECESSARY TO
TAKE CONSIDERATION THE FOLLWING ITEMS ON ATTACHMENT TO A FRAME.
CUSTOM’S HOUSING
EXAMPLE OF MOUNTING

LOCATION OF SPACERS
(1) USE OF PROTECTIVE PLATE,MADE OF AN ACRYLIC PLATE, ETC, IN ORDER TO
PROTECT A POLARIZER AND LC CELL.
(2) TO PREVENT THE MODELE COVER FROM BEING PRESSES, 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
PROTEXTING LCD MODULE FROM ANY KIND SHOCK TO YOU SET.
11.2 LC DRIVING VOLTAGE(V0) AND VIEWING ANGLE RANGE.

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 OPERATOE’S BODY IS REQUIRED
WHEN HANDLING IT.
11.4 POWER ON SEQUENCE
INPUT SIGNALS SHOULD NOT BE APPLIED TO LCD MODULE BEFORE POWER
SUPPLY VOTAGE IS APPLIED AND REACHES TO SPECIFIED VOLTAGE(5+/-0.25V)
IF ABOVE SEQUENCE IS NOT LEPT, C-MOS LSIS 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 OF HIGHER. SPECIAL CARE TO PREVENT THEM FROM
HIGH HUMIDITY IS REQUIRED. A COMBINATION OF HIGH TEMPERATURE AND
HIGH HUMIDITY MAY CAUSE THEM POLARIZATION DEGRADATION DEGRADATION
AS WELL AS BUBBLE GENETRATION AND POLARIZER PEEL-OFF. PLEASE KEEP
THE TEMPERATURE AND HUMIDITY WITHIN THE SPECIFIED RANGE DOR 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 POLARIZERS AND
ALUMUNUM PLATES ARE MADE OF ORGANIC SUBSTANCES WHICH WILL BE
DETERIORATED BY A CHEMICAL REACTION WITH SUCH CHEMICALS AS
ACETONE,TULUENE ETHANOLE AND ISOPROPYLALCOHOL. 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 OR WATER DROP ATTACHHED ON THE
DISPLAY AREA BECAUSE ITS LONG PERIOD ADHERANCE MAY CAUSE
DEFORMATION OR FADED COLOR ON THE SPOT.
(6) FOGY DEW DEPOSITED ON THE SURFACE AND CONTACT TERMINALS DUE TO
COLDENESS WILL BE A 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 FOR 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 POOB INSULATION BETWEEN TERMINALS ARE OFTEN
CAUSED BY BEING TOUCHED BY BARE HANDS.
(THERE ARE SOME COME COSMETICS DETRIMENTAL TO POLARIZERS.)
(8) IN CENERAL THE QUALITY OF GLASS IS FRAGILE SO THAT IT TENDS TO BE
CRACKED OR CHIPPED IN HANDLING, SPECIALLY ON ITS PERIPHERY.
PLEASE BE CAREFUL NOT GIVE IT SHAPR SHOCK CAUSED BY DROPPING
DOWN, ETC.
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 LIMIT CAUSES THE
SHORTER LCD LIFE. AN ELECTROCHEMICAL REACTION DUE TO DIRECT
CURRENT CAUSES LCD’S UNDESIRABLE DETERIORATION, SO THAT THE USE
OF DIRECT CURRENT DRIVER SHOULD BE AVOIDED.
(2) RESPONSE TIME WILL BE EXTREMELY DELAYED AT LOWER TEMPERATURE
THAN THE OPERATING TEMPERATURE RANGE AND ON THE OTHER HAND AT
HIGHER TEMPERATURE LCD’S SHOW DARK BULE COLOR IN THEN.HOWEVER
THOSE PHENOMENA DO NOT MEAN MALFUNCTION OR OUT OF ORDER WITH
LCD’S WHICH WILL COME BACK IN THE SPECIFIED OPERATING TEMPERATURE
RANGE.
(3) IF THE DISPLAY AREA IS PUSHED HARD DURING OPERATION,SOME FONT
WILL BE ABNORMALLY DISPLAYED BUT IT RESUMES NORMAL CONDITION
AFTER TURNING OFF ONCE.

No.
(4) A SLIGHT DEW DEPOSITING ON TEMPINALS IS A CAUSE FOR ELECTROCH EMICAL REACTION RESULTING IN TERMINAL OPEN CIRCUIT. USAGE UNDER
THE RELATIVE CONDITION OF 40°C 50%RH OR LESS IS REQUIRED.
11.7 STORAGE
IN CASE OF STORING FOR A LONG PERIOD OF TIME (FOR INSTANCE, FOR
YEARS) FOR THE PURPOSE OF REPLACEMENT USE, THE FOLLOWING WAYS
ARE RECOMMENED.
(1) STORAGE IN A PLOYETHYLENE BAG WITH THE OPENING SEALED SO AS NOT
TO ENTER FRESH AIR OUTSIDE IN IT. AND WITH NO DESICCANR.
(2) PLACING IN A DARK PLACE WHERE NEITHER EXPOSURE TO DIRECT SUNLIGHT
NOR LIGHT IS, KEEPING TEMPERATURE IN THE RANGE FROM 0°C TO 35°C
(3) STORING WITH NO TOUCH ON POLARIZER SURFACE BY ANYTHING ELSE.
(IT IS RECOMMENDED TO STORE THEM AS THEY HAVE BEEN CONTAINED IN
THE INNER CONTAINER AT THE TIME OF DELIVERY FROM US.)
11.8 SAFETY
(1) IT IS RECOMMENDABLE TO CRASH DAMAGED OR UNNECESSARY LCD’ INTO
PIECES AND EASH OFF LIQUID CRYSTAL BY EITHER OR SOLVENTS SUCH AS
ACETONE AND ETHANOL, WHICH SHOUD BE BURNED UP LATER.
(2) WHEN ANY LIQUID LEAKED OUT OF A DAMAGED GLASS CELL COMES IN
CONTACT WITH YOUR HANDS, PLEASE WASH IT OFF WELL WITH SOAP AND
WATER.
