Sab nraum zoov TFT LCD zaub cov qauv ua haujlwm nyob rau hauv ib puag ncig sib txawv ntau dua li cov neeg tau txais kev ua tau zoo, yog li muab cov kev xav tau tshwj xeeb rau lawv.
Cov kev xav tau no suav nrog lub teeb ci siab, tiv thaiv kev sib tsoo, anti {} saib, siab tiv taus ulteriolet (UV) hluav taws xob.
Ntawm cov yuav tsum tau ua, "UV Kuj" feem ntau hais, tab sis ntau tus neeg tsis paub txog nws txoj kev siv tshwj xeeb.
Thaum tham txog kev tiv thaiv kev tiv thaiv UV sab nraum zoov LCD Zaub Modules, ntau tus yuav paub txog "U6}} {tiv taus oca," tab sis muaj lwm txoj hauv kev?
Kab lus no yuav Systemsatically qhia cov kev tiv thaiv UV cov kev tiv thaiv UV
Hais Txog UV Teeb
Ua ntej qhia cov kev daws teeb meem tshwj xeeb, cia peb ua ntej muaj kev nkag siab yooj yim ntawm ultraviolet (UV) lub teeb.
Lub teeb tuaj yeem faib ua ob peb pawg raws li nws nthwv dej: pom pom lub teeb uas feem ntau muaj nthwv dej ntawm 380 thiab 780 nm; Ultraviolet (UV) muaj nthwv dej muaj ntau yam ntawm 100 txog 400 nm (ib nrab sib tshooj nrog pom lub teeb); wavelengths tsawg dua 100 nm yog x - ray; Thiab wavelengths ntau dua 780 nm muaj rau infrared hluav taws xob.
Ultraviolet (UV) tuaj yeem txuas ntxiv tau los ntawm nthwv dej raws li nram no:
Ntev - yoj Uva (315 ~ 400n)
Nruab nrab - waim awv UVB (280 ~ 315NM)
Luv - wave vc (100 ~ 280nm)
Los ntawm lub zog pom kev, UV {- c> U6 -- a; Txawm li cas los xij, nyob rau hauv cov nqe lus ntawm kev faib tawm nyob rau hauv lub ntuj ib puag ncig, UV {}}}}}}}}} {8} {8} {8} {8} {8} {8} {8} {8} {8} {8} {8} {8} {8} {8} {8} {8} {8} {8} {8} {8} {8} {8} {8} {8} {8} {8} {8} {8} {8} {8} {8} {8} {8} {8} {8} {8} {8} {8} {8} {8} {8} {8} {8} {8} {8} {8} {8} {8}-
Yog li ntawd, thaum peb tham txog LCD kev tiv thaiv, peb tsuas yog xa mus tiv thaiv ntev {{waim ura.
Tom qab kawm cov hauv paus ntawm ultraviolet hluav taws xob, cia saib ntawm cov kev tiv thaiv UV feem ntau siv rau sab nraum zoov LCD zaub Modules.
Anti -} Uv oca optical adhesive
Anti-UV OCA optical adhesive, also commonly known as "UV CUT OCA," is almost standard equipment for outdoor LCD display modules and is one of the most widely used UV protection methods. Nws yog ib qho tseem ceeb kom nco ntsoov tias hom OCA no feem ntau tsis yog- U6 {3} kho tus kheej).
Dhau li ntawm sab nraum zoov LCD zaub Modules, anti {{}}}}}}}}}}}}}}}}}}}}}}}}}} Xav tau UV hluav taws xob, thiab raug tsaj lossis tsis xwm yeem cov zaub ua ke.
Tus txheej txheem ua hauj lwm ntawm anti - UV oca
Zoo tib yam oca optical adhesives tsuas yog muaj cov resin, cov neeg sawv cev sib ntxiv, thiab tsis muaj kev tiv thaiv tau muaj kev tiv thaiv UV UV tiv thaiv UV.
Anti - UV Oca, txawm li cas los xij, ntxiv "anti - UV additives" rau tus qauv no. Cov yeeb yaj kiab no tau zoo ua tau zoo- Zog tsim hluav taws xob, yog li tiv thaiv UV teeb los ntawm kev ua kom muaj tsheb ciav hlau LCD.
UV Oca thaiv cov muaj peev xwm
Cov lus qhia tshwj xeeb feem ntau muab cov ntaub ntawv hloov pauv rau lub 340 ~ 380nm yoj yoj. UV hloov pauv hauv qab 340nm yog qhov kawg xoom. Rau tej nthwv wavelength thaiv yuav tsum muaj, kev hloov chaw yuav raug sim kom haum.
Muaj ob txoj hauv kev los nthuav tawm qhov no:
a. UV (340 ~ 380nM) kis tau transmittion <0 ~ 1%: qhov qis dua tus nqi, qhov zoo dua cov nyhuv thaiv.
b. UV (340 ~ 380nm) nqus / thaiv tus nqi> 97 ~ 99%: Cov nqi uas muaj zog dua, muaj zog dua cov kev thaiv cov peev xwm.
Uv {-} tiv taus inks
Siv UV {-} tiv taus inks hauv sab nraum zoov LCD modules tsis yog yuav tsum tau; Lawv txoj kev xaiv yog nyob ntawm cov khoom yuav tsum tau thiab kev txiav txim siab tau txais.
Txawm li cas los xij, vim tias cov khoom sab nraum zoov feem ntau yog nthuav tawm hnub ci, los nag (CG)
Cov lus qhia pom zoo
UV {{- Tsis txaus siab inks tau pom zoo hauv cov xwm txheej hauv qab no:
Thaum tus neeg yuav khoom tau qhia meej UV tiv thaiv kev kuaj mob rau CG Cover Phaj;
Thaum cov neeg siv khoom yuav tsum tau LCD module ua kom tiav "cov khaub ncaws dub" cov nyhuv;
Thaum cov xim number case yog nquag thab tom qab UV iurradiation, cuam tshuam rau kev sib xws ntawm tsos, xws li cov phiaj dawb.
Mechanism ntawm UV -} tiv taus inks
Dog dig dog dig feem ntau muaj cov pigments, khi, thiab kev ua haujlwm ntxiv:
Pigments: Txheeb xyuas cov xim, xws li carbon dub (dub) thiab titanium dioxide (dawb). Qee cov pigments muaj cov qauv ruaj khov thiab muaj qee qib ntawm kev teeb pom kev zoo.
Kev kho: xws li epoxy resins thiab polyesters, lawv ua raws li cov nqa khoom rau cov pigments thiab ua yeeb yaj kiab tiv thaiv tom qab kho tau.
Kev ua kom muaj kev sib ntxiv: xws li kev kho cov neeg sawv cev thiab cov neeg sawv cev theem, siv los kho tus mem kua zog.
UV {-} Tiv thaiv inks, ntxiv rau cov khoom siv no, muab cov teeb pom kev ruaj khov. Cov cabilizers no nyiam nqus kev teeb tsa ultraviolet thiab hloov nws mus rau hauv tshav kub, yog li tiv thaiv cov number case txheej los ntawm kev puas tsuaj.
Anti - UV Polarizing Zaj Duab Xis (Pol)
Txawm hais tias ib tug ncej duab ua yeeb yaj kiab muaj ov anti - UV zog yog ib yam ntau cov neeg tsis paub txog. Qhov tseeb, Polarizing cov yeeb yaj kiab tuaj yeem muab faib ua los tiv thaiv- UV thiab tsis {{4 {UV hom.
Anti - UV Polarizing cov yeeb yaj kiab sib xyaw UV nqus mus rau txheej tac, yog li thaiv UV rays. Thaum xaiv cov yeeb yaj kiab polarizing, nws yog qhov tseem ceeb kom paub meej nrog tus xa khoom txawm nws txhawb UV tiv thaiv.
Tam sim no, feem ntau siv cov ntaub ntawv tiv thaiv tiv thaiv rau cov yeeb yaj kiab polarizing yog TAC, PMMA, cop, thiab tsiaj. Ntawm lawv:
Cop: Tsis muaj zog UV kev tiv thaiv kev ua tau zoo
Tus tsiaj: me ntsis zoo dua li tub luam
PMMA thiab TAC: Kev Tiv Thaiv Uv Kev Tiv Thaiv Zoo
PMMA muaj tus nqi qis tab sis tsis muaj dej tsis haum, thiab feem ntau siv nyob rau hauv loj- loj beks; TAC feem ntau siv nyob rau hauv me me thiab nruab nrab- ci siab- kev ntseeg tau.
UV {- Resistant iav Npog
UV {- Tsis muaj dav iav npog tau siv nyob rau hauv kev lag luam hauv tsheb thiab cov neeg tau txais kev lag luam, txawm hais tias lawv siv tau nce zuj zus nyob rau hauv xyoo tas los no.
Lub hauv paus ntsiab lus tom qab lawv yog qhov sib ntxiv ntawm cov hlau oxides xws li cinexide, titanium oxide, thiab hlau oxide rau cov khoom siv iav. Cov khoom sib xyaw no tau nqus cov ultraviolet rays, tab sis kuj tseem cuam tshuam rau pom lub teeb kev hloov pauv thiab xim ntawm lub khob.
Feem ntau hais lus, lub teeb pom kev hloov pauv ntawm UV -} Cov iav tiv taus yog li ib nrab ntawm cov iav dog dig; UV Thaiv Cov nyhuv yog cuam tshuam rau lub khob tuab - qhov ntau dua UV kev hloov pauv.
Phau Ntawv Qhia Kev Txiav Txim Siab: Yuav ua li cas xaiv thiab sib koom ua ke?
Cov Ntawv Thov Yooj Yim: UV {- tiv taus OCA yog qhov yuav tsum tau ua.
High thiaj yuav tsum muaj rau tsos thiab huab cua kuj: ntxiv UV {{}} tiv taus number case rau OCA Base.
Tej yam yuav ntseeg tau: tib {{free} tiv taus OCA - UCH {}} tiv thaiv polarizer tuaj yeem tsim "dual kev tiv thaiv."
Kev ua tiav qhov kev ua tau zoo kawg nkaus thiab kev sib xyaw ua ke: xav txog kev siv UV {{}} awnant iav npog thiab kho lwm yam kev txhawb nqa tau raws li.
Thaum kawg, cov kev daws teeb meem zoo ib txwm yog qhov tshwm sim los ntawm kev ntsuas khoom lag luam, cov qauv kuaj, thiab nyiaj txiag siv nyiaj. Nkag siab txog cov txheej txheem thiab muab tso rau ntawm txhua qhov kev daws teeb meem yog qhov tseem ceeb rau kev sib txuas nrog hloov tau thiab tsim cov khoom lag luam sab nraum zoov txhim khu kev qha.
