11. PRECAUTION IN DESIGN
11.1 MOUNTING METHOD
SINCE THE MODULE IS SO CONSTRUCTED AS TO BE FIXED BY
UTILIZING FITTING HOLES IN THE PRINTED CIRCUIT BOARD AS
SHOWN BELOW, IT IS NECESSARY TO TAKE CONSIDERATION THE
FOLLOWING ITEMS ON ATTACHMENT TO A FRAME.

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 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.
11.2 LC DRIVING VOLTAGE(VEE) AND VIEWING ANGLE RANGE.
SETTING VEE OUT OF THE RECOMMENDED CONDITION WILL BE A
CAUSE FOR A CHANGE OF 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 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.

(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
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 BLUE
COLOR IN HEM.HOWEVER THOSE PHENOMENA DO NOT MEAN
MALFUNCTION OR OUT OF ORDER WITH LCD‘S WHICH WILL COME
BACK IN THE SPECIFIED OPERATING TEMPER ATURE 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.

(4) A SLIGHT DEW DEPOSITING ON TERMINALS IS A CAUSE FOR
ELECTROCHEMICAL REACTION RESULTING IN TERMINAL OPER CIRCUIT.
USAGE UNDER THE RELATIVE CONDITION OF 40°C 50%RH LESS IS
REQUIRED.
11.7 STORAGE
IN CASE OF STORING FOR A LONG PERIOD TIME (FOR INSTANCE,FOR
YEARS) FOR THE PURPOSE OF REPLACEMENT USE,THE FOLLOWING WAYS
ARE RECOMMENDED.
(1) STORAGE IN A POLYETHYLENE BAG WITH THE OPENING SEALED SO
AS NOT TO ENTER FRESH AIR OUTSIDE IN IT,AND WITH NO
DESICCANT.
(2) PLACING IN A DARK PLACE WHERE NEITHER EXPOSURE TO DIRECT
SUNLIGHT NOR LIGHT IS, KEEPING TEMPERATURE IN THE RANGE
FOR 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
FOR US.)
11.8 SAFETY
(1) IT IS RECOMMENDABLE TO CRASH DAMAGED OR UNNECESSARY
LCD‘S INTO PIECES AND WASH OFF LIQUID CRYSTAL BY EITHER
OF SOLVENTS SUCH AS ACETONE AND ETHANOL, WHICH SHOUD UP
LATER.
(2) WHEN ANY LIQUID LEAKED OUT OF A DAMAGED GLASS CELL IN
CONTACT WITH YOUR HANDS, PLEASE WASH IT OFF WELL WITH
SOAP AND WATER.
