Cov txheej txheem tsim khoom ntawm lub vijtsam kov zoo ib yam li cov txheej txheem tsim khoom ntawm cov kua siv lead ua kua vaj huam sib luag hauv ntau qhov chaw. Nyob rau hauv ob qho tib si, pob tshab electrodes yog tsim los ntawm ob qho kev tawm tsam substrates, thiab tom qab ntawd cov ntaub ntawv ua haujlwm tau luam tawm ntawm cov pob tshab electrodes los ua tus qauv, thiab tom qab ntawd cov txheej txheem sab saud thiab sab qis yog sib koom ua ke thiab xa mus rau cov txheej txheem kawg.
Feem ntau ntawm cov chaw tsim tshuaj ntsuam kov ncaj qha yuav cov substrates nrog pob tshab electrodes tsim, thiab siv lawv rau lub tuam txhab kev tsim khoom. Cov iav qis qis nqis peev feem ntau yog lub cim thib ob ntawm cov kua siv lead ua kua zaub panels nrog qhov loj ntawm 370_ x 470mm lossis 400mm x 500mm; cov yeeb yaj kiab sab saud Ncaj nraim yuav 650mm lossis 1000mm yob zaj duab xis, tom qab ntawd txiav nws raws li qhov tsim nyog loj thiab muab tso rau hauv cov txheej txheem tsim khoom tom ntej.
Cov pob tshab electrode qauv ua txoj kev sib txawv ntawm cov kua siv lead ua kua vaj huam sib luag. Cov kua siv lead ua kua zaub panels siv photolithography los ua cov qauv pob tshab electrode, uas xav tau cov ntaub ntawv resin nrog cov duab zoo nkauj thiab cov khoom kim heev thiab cov khoom tsim kho. Muaj ntau txoj hauv kev hauv qab no los ua pob tshab electrodes ntawm cov ntxaij vab tshaus kov.
① Sau cov khoom siv photosensitive ntawm txoj hauj lwm ntawm cov pob tshab electrode ntawm cov khoom, thiab siv nws ua lub npog ntsej muag kom tshem tawm qhov tsis tsim nyog ntawm cov pob tshab electrode.
② Insulating zaj duab xis yog luam tawm qhov uas tsis xav tau pob tshab electrodes.
③ Tsim thiab ua pob tshab electrodes nrog laser.
Piv nrog rau lub vaj huam sib luag LCD, cov qauv ntawm cov pob tshab electrode ntawm lub vijtsam kov yog qhov yooj yim heev. Txij li cov txheej txheem photolithography kim tsis tas yuav tsum tau ua, ntau lub tuam txhab xaiv cov txheej txheem tsim khoom qis kom ntau li ntau tau los ua pob tshab pixel electrodes. Yav dhau los, txoj kev ①, txoj kev ②, los yog siv lub teeb los ua pob tshab pixel electrodes feem ntau yog siv. Tsis ntev los no, cov txheej txheem ntawm kev siv laser ua cov pob tshab electrodes tau maj mam nce.
Txawm hais tias cov khoom siv laser ua tsis pheej yig, nws yuav tsum muaj qhov chaw tsawg dua. Tsis tas li ntawd, txoj kev ua laser yog pom tau los ntawm cov txheej txheem qhuav, tsis tas yuav tsum muaj txheej txheem ntub dej, thiab kev kho cov kua khib nyiab raug tshem tawm, uas yog qhov zoo heev rau kev ua ntawm ITO nyias zaj duab xis. Nws cov chaw tsim khoom tsim khoom sawv cev yog Ultech.
Tom qab lub pob tshab pixel electrode qauv tsim, cov kua nplaum nyiaj yog luam tawm ntawm txhua lub substrate, thiab tom qab ntawd ib lub voj voog ncig yog teem rau ntawm ib sab ntawm lub substrate, thiab tom qab ntawd ob lub substrate yog sib koom ua ke. Txoj kev sib txuas ntawm ob lub substrates yog tib yam li cov kua siv lead ua kua vaj huam sib luag. Ib txhia ua ntej luam cov thav duab sealant, thiab tom qab ntawd siv cov cua sov los yog UV irradiation los kho cov thav duab sealant, thiab qee qhov siv ob-sided adhesives thiab lwm cov nplaum rau kev sib txuas.
Tom qab ua tiav qhov kev sib txuas ntawm ob lub substrates, FPC tom qab ntawd muaj kev sib raug zoo. Cov kua siv lead ua kua yog laminated nyob rau hauv lub xeev ntawm thiaj li hu ua molher iav. Txawm li cas los xij, TP feem ntau yog qhov me me ua ntej, thiab tom qab ntawd txuas rau lub vaj huam sib luag ntawm qhov teeb tsa loj.
capacitive (projection type) touch screen, tsuas yog siv ib lub iav substrate. Qhov txawv ntawm cov txheej txheem kov cov tshuaj tiv thaiv yog tias txheej txheej thiab txheej txheem rov ua dua ntawm iav substrate. Qhov no yog kev tsom xam ntawm lub capacitive touch screen manufacturing txheej txheem.
