Dab tsi yog cov yam ntxwv ntawm lub vijtsam feem ntau ntawm TFT kua? Cov khoom tseem ceeb yog: thaj chaw loj, kev sib koom ua ke siab, muaj nuj nqi muaj zog, tus nqi qis, cov txheej txheem hloov tau, thiab daim ntawv thov dav dav. Hauv qab no peb yuav qhia ntau yam ntxwv ntawm TFT LCD npo hauv kev nthuav dav.
(1) Loj cheeb tsam: Nyob rau hauv thaum ntxov 1990s, thawj-tiam loj-qhov chaw iav substrate (300mmx400mm) TFT-LCD ntau lawm kab tau muab tso rau hauv ntau lawm. Los ntawm thawj ib nrab ntawm 2000, thaj tsam ntawm cov iav substrate tau nthuav dav mus rau 680mm × 880mm). Tsis ntev los no, iav substrate ntawm 950mmx1200mm kuj tseem yuav muab tso rau hauv kev ua haujlwm.
(2) Kev sib koom ua ke siab: 1.3-nti TFT nti siv rau cov kua siv lead ua kua muaj qhov kev daws teeb meem ntawm XGA uas muaj ntau lab pixels. Lub 16.1-nti TFT array nrog kev daws teeb meem ntawm SXGA (1280 × 1024), zaj duab xis tuab ntawm amorphous silicon tsuas yog 50nm, thiab TABONGLASS thiab SYSTEMONGLASS thev naus laus zis, kev sib koom ua ke ntawm ICs, cov khoom siv thiab cov khoom siv thev naus laus zis, thiab kev siv tshuab nyuaj tshaj cov tsoos tsho. LSI.
(3) Lub zog muaj zog: TFT yog thawj zaug siv los ua qhov chaw nyob hauv matrix los txhim kho lub teeb lub teeb ntawm cov kua muaju. Rau cov kev daws teeb meem siab, los ntawm kev hloov kho qhov hluav taws xob hauv thaj tsam ntawm 0-6V (tus nqi raug yog 0.2 txog 4V), kev tswj xyuas meej ntawm cov khoom siv tau paub, uas ua rau nws ua tau rau LCD kom ua tau zoo thiab siab. - daws teeb meem zaub.
(4) Tus nqi qis: Cov iav substrate thiab cov yas substrate hauv paus daws teeb meem tus nqi ntawm cov khoom siv hluav taws xob loj sib xyaw ua ke, thiab qhib qhov chaw dav dav rau daim ntawv thov ntawm cov khoom siv loj semiconductor integrated circuits.
(5) Cov txheej txheem yooj yim: Ntxiv rau kev tsim zaj duab xis siv cov txheej txheem ib txwm siv xws li sputtering, CVD (chemical vapor deposition), MCVD (molecular chemical vapor deposition), thiab lwm yam., laser annealing tshuab kuj tau pib siv, uas tuaj yeem tsim amorphous. films, polycrystalline films, thiab ib leeg siv lead ua films tuaj yeem tsim. Nws tuaj yeem tsis tsuas yog ua silicon zaj duab xis xwb, tab sis kuj ua rau lwm pawg II-VI thiab III-V pawg semiconductor nyias zaj duab xis.
(6) Daim ntawv thov teb yog dav. Lub LCD vaj huam sib luag vaj huam sib luag raws li TFT thev naus laus zis yog lub hauv paus kev lag luam ntawm cov ntaub ntawv hauv zej zog. Cov thev naus laus zis kuj tseem tuaj yeem siv rau kev loj hlob sai sai ntawm nyias zaj duab xis transistor organic electroluminescence (TFT-OLED) vaj huam sib luag tiaj tus. Loj hlob.
