15 Handling Precautions
Mountingmethod 
Donotmakeextraholesinthedisplayormodifyitsshape.Whenmountingthedisplay,ensurethatthedisplaydoesnotflex,
bendortwist.ExtremecareshouldbeusedwhenhandlingtheLCDmodules.

LCDHandlingandCleaningPrecaution 
Tocleanthedisplaysurface,itisrecommendedtowipelightlyusingasoftclothwitheitherIsopropylalcoholorEthylalcohol.
Donotwipethedisplaysurfacewithdryorhardmaterialsasitmaydamagethepolarizersurface.
DonotuseWaterorAromaticstocleanthedisplay.
DonotwipeITOpadareawithdryorhardmaterialsthatwilldamagetheITOpatterns
DonotuseSolderingflux,Chlorine(Cl),andSulfur(S)onthepadorpreventitfrombeingcontaminated.
Ifthedisplayissentwithoutapplyingasiliconcoatonthepad,theITOpatternscouldbedamagedduetocorrosionastime
goeson.
IfITOcorrosionoccursduetocustomermiss‐handling,orifthecustomerappliesmaterialssuchasChlorine(CI),Sulfur(S)to
thedisplay,theresponsibilityisplacedthecustomer.

StaticChargePrecaution
TheLCDmoduleusesCMOSLSIdrivers,sowerecommendthatyou:
ConnectanyunusedinputterminaltoVDDorVSS
Donotinputanysignalsbeforepoweristurnedon
Groundyourbody,work/assemblyareas,andassemblyequipmenttoprotectagainststaticelectricity.
Packing
ThemoduleemploysLCDelementsandmustbetreatedassuch.
Avoidintenseshockandfallsfromaheight.
 Topreventmodulesfromdegradation,donotoperateorstorethemexposeddirecttosunshineorhigh
temperature/humidity

PrecautionsduringOperation
ItisanindispensableconditiontodrivetheLCDmodulewithinthespecifiedvoltagelimits.Applyingvoltagehigher
thanthelimitwillreducethelifespanoftheLCD.
Usingdirectdrivecurrentshouldbeavoided,asitwillinduceanelectrochemicalreactioncausingundesirable
deterioration.
TheLCD’sresponsetimewillbedelayedwhenoperatingatatemperaturelowerthanthesuggestedoperatingrange.
Whenoperatingatatemperaturehigherthanthesuggestedrange,theLCDwillbenoticeablydarker.Thedisplaywill
returntonormalwhenitisbroughtbacktothespecifiedoperationtemperature.
Ifthedisplayareaispushedhardduringoperation,somefontmaybeabnormallydrawnbuttheLCDwillreturnto
normalafteritisreset.
Slightdewdepositingonterminalscancauseanelectro‐chemicalreaction,damagingtracesandresultinginanopen
circuit.
Usageunderthemaximumoperatingtemperature,50%Rhorlessisrequired

StorageRecommendations
WhenstoringtheLCDforaprolongedperiodoftime,thefollowingrecommendationswillhelppreventdamageor
deterioration
Storethedisplayinanambienttemperaturerangebetween10°Cto30°C,andinarelativehumidityof45%to75%.

15

Donotleavethedisplayexposedtosunlightorfluorescentlight.
Placethedisplayinapolyethylenebagwiththeopeningsealed.
Ensurethatnothingismakingcontactwiththepolarizersurface.
Itisrecommendedtostoretheminthesamepackagingthatwasprovideduponpurchase

SafetyPrecautions
InthecasethattheLCDglasshasshattered,itisrecommendedtoremoveanyglasspieces,washofftheliquidcrystalusing
eitheracetoneorethanol,andproceedtoburnanyremainingdisplaypieces.
Ifanyliquidleakedoutofadamagedglasscell,andcomesincontactwithyourhands,pleasewashitoffwellwithsoapand
water
