Hauv xyoo 2007, kev lag luam kov npo yog nyob rau theem ntawm 200 billion yen. Nws tau nkag siab tias qhov kov cov ntxaij vab tshaus muaj 75 feem pua ntawm tag nrho cov kev lag luam kov npo, thiab tau loj hlob ntawm tus nqi ntawm 15 feem pua rau 20 feem pua txhua xyoo. Ntau tshaj 90 feem pua ntawm cov ntxaij vab tshaus kov nrog cov kua siv lead ua kua ua ke yog cov tshuaj tiv thaiv kov. Kev ua lag luam thiab kev sib txawv ntawm cov khoom siv kov cov tshuaj tiv thaiv yog cov ntsiab lus raws li tus sau qhov kev xav.
Tsis ntev los no nthuav rro zaj duab xis ua lag luam tau nyiam heev. Tsis tsuas yog cov tuam txhab ito uas twb muaj lawm tau nce ntau lawm, tab sis kuj muaj ntau lub tuam txhab tshiab tau tshwm sim los kawm lwm yam ito cov ntaub ntawv. Nws tuaj yeem pom los ntawm Table 5-1 tias cov khoom sib xyaw ntawm lub vijtsam kov tau muab faib ua sab saum toj (movable) electrode ITO zaj duab xis substrate, hauv qab (tso) electrode ITO iav substrate, FPC, optical film, thiab peripheral bonding khoom.
Yuav luag tag nrho cov khoom siv pob tshab siv hauv vaj huam sib luag yog ITO. Txawm hais tias cov kws tshawb fawb tau kawm cov ntaub ntawv uas tuaj yeem hloov ITO rau lub sijhawm ntev, txog tam sim no, tseem tsis muaj cov khoom siv uas tuaj yeem hloov ITO raws li kev ua tau zoo. ITO iav substrate yog ib qho tsim nyog raw khoom rau kua siv lead ua kua panels thiab muaj kev lag luam loj.
LCD manufacturers kuj muab tso rau hauv cov khoom siv sab hauv. Ntau tshaj 95 feem pua ntawm ITO zaj duab xis substrates yog siv hauv cov ntxaij vab tshaus. Hauv qhov sib piv, cov khoom siv hluav taws xob hluav taws xob (EL) thiab cov kua siv lead ua kua ua kua (suav nrog cov ntawv hluav taws xob) tsis tshua siv, thiab tus nqi nyob tsawg dua 1/100.
Raws li kev txheeb cais, kev lag luam loj ntawm IT0 zaj duab xis substrates hauv xyoo 2007 yog 4 lab m2, uas ntau dua 90 feem pua tau siv rau cov ntxaij vab tshaus kov. Txawm li cas los xij, tsis ntev los no, ITO zaj duab xis tau pib siv rau qhov projection-type capacitive touch screens, uas yog qhov chaw loj hlob tshiab rau ITO zaj duab xis substrates. Nrog rau kev nthuav dav txuas ntxiv ntawm qhov projection hom capacitive touch screen lag luam, nws zoo li yuav loj hlob ntawm tus nqi ntawm 1 lab square metres hauv ib xyoos, ncav cuag kev lag luam ntawm 50 billion yen.
Qib crystallization ntawm ITO zaj duab xis qauv ncaj qha cuam tshuam rau cov yam ntxwv ntawm lub vijtsam kov. Cov yeeb yaj kiab zoo ntawm ITO yog ze ze rau cov txheej txheem txheej txheem ntawm cov chaw tsim khoom. Vim yog qhov yuav tsum tau ua ntawm cov khoom siv kho qhov muag, ITO zaj duab xis tsis yog tsim ncaj qha rau ntawm nyias zaj duab xis substrate, tab sis tom qab kev kho mob xws li txo kev cuam tshuam fringes, tiv thaiv kev cuam tshuam, txhim kho qhov tawv tawv, txhim kho viscosity, thiab kev kho mob antifouling, ITO zaj duab xis yog tsim los ntawm nyias zaj duab xis substrate. . Qhov tseeb, tsuas yog siv ITO zaj duab xis raws li sab saum toj electrode yog txaus kom ua tau raws li cov yam ntxwv ntawm kev kov.
Ib qho ntawm cov yam ntxwv ntawm lub vijtsam kov nrog cov kua siv lead ua kua ua ke yog tias nws yuav tsum muaj kev xa tawm siab. Lub transmittance ntawm lub resistive kov screen yog txiav txim los ntawm lub transmittance ntawm lub sab saum toj electrode cov khoom thiab cov khoom hauv qab electrode. Feem ntau, kev xa tawm ntawm sab sauv ITO zaj duab xis substrate ntawm lub vijtsam kov yog li 88 feem pua , thiab kev xa tawm ntawm sab qis ITO iav substrate yog li 90 feem pua, yog li qhov kev xa tawm ntawm lub vijtsam kov yog li 78 feem pua. Txawm hais tias kev xa tawm ntawm ITO iav tau mus txog 97 feem pua , 92 feem pua kev xa tawm ntawm ITO zaj duab xis substrates ntawm kev ua lag luam yog qhov zoo, thiab tib neeg tab tom tos ntsoov rau qhov tshwm sim ntawm ITO zaj duab xis substrates nrog kev xa tawm ntau dua 95 feem pua.
