TFT tshuab tau tsim nyob rau hauv 1990s. Loj-nplai hluav taws xob cov khoom siv yees tshiab thiab cov txheej txheem tshiab yog siv ua kua siv lead ua kua (LC), cov duab thaij thiab organic organic electroluminescent (EL thiab OEL) cov lus qhia hauv plag. hauv paus. Lub TFT yog tsim los ntawm cov khoom tsis zoo ib yam xws li iav los yog yas substrate (nyob rau ntawm wafer, ntawm chav kawm) los ntawm kev ua pa, cov txheej txheem tshuaj lom neeg, thiab ntau cov yeeb yaj duab uas tsim nyog rau cov khoom tsim tawm, thiab ib qhov loj ntawm cov semiconductor Circuit Court (LSIC) tau tsim los ntawm kev ua yeeb yam. . Kev siv cov khoom uas tsis yog-ib-qia substrates tuaj yeem txo cov nqi, uas yog kev txuas ntxiv ntawm cov kab kev sib txuas ua ke loj rau cov cheeb tsam loj, kev ua haujlwm, thiab cov cuab yeej tsawg. Fabricating TFTs uas tswj pixel (LC lossis OLED) hloov kev ua haujlwm ntawm qhov loj thaj iav lossis yas substrates yog qhov yooj yim dua ua loj loj ICs ntawm silicon wafers. Cov kev cai ntawm cov khoom tsim tawm (purity yog 100), purity ntawm cov ntaub ntawv raw (lub purity ntawm cov hluav taws xob tshwj xeeb yog 99.999985%), cov khoom siv rau kev tsim khoom thiab kev siv tshuab ntau tshaj qhov loj ntawm kev sib tos ntawm cov khoom sib txuas, thiab nws yog lub siab ntawm niaj hnub kev tsim. technology. Nws lub ntsiab nta yog:
(1) Kev siv cov cwj pwm zoo: cov kev siv qis tsis muaj zog, kev tsav tsheb tsawg, kev siv lub xeev siv kev nyab xeeb zoo thiab kev cia siab; tiaj tus, nyias, txuag ntau ntawm cov ntaub ntawv raw thiab siv chaw; tsis muaj hwj chim ntau, nws lub hwj huam siv tau yog hais txog CRT monitors One-tenth ntawm qhov ntawd, qhia TFT-LCDs tsuas yog li ib-puasthawj ntawm CRT, uas txuag ntau zog; Cov khoom TFT-LCD kuj muaj cov qauv, koob series, ntau hom, yooj yim thiab yoog raws siv, kho thiab hloov tshiab. , yooj yim mus upgrade, lub neej ntev thiab ntau lwm yam nta. Cov zaub ntau qhov sib npaug ntawm daim ntawv thov txhua yam ntawm 1 inch txog 40 ntiv tes thiab dav dav dav dav dav hlau, yog qhov dav hlau puv npo loj; tso saib zoo los ntawm kev sim cov duab monochrome ua cim loj rau siab, siab xim fidelity, High-brightness, high-contrast, high-response speed video zaub ntawm ntau yam kev qhia; ncaj-saib, kwv yees, kev xav, thiab kev xav.
(2) Raug kev siv tshuab muaj qib siab ntawm automation, thiab loj-scale industrial ntau lawm nta zoo. TFT-LCD kev lag luam technology yog paub tab, kev tsim cov khoom loj ntawm cov khoom loj muaj ntau tshaj 90%.
(3) TFT-LCD yog ib qho yooj yim los ua ke thiab hloov, thiab nws yog ib qho zoo sib xws ntawm cov txheej txheem loj ntawm high-semiconductor integrated circuit technology thiab light source technology, thiab muaj peev xwm zoo rau kev loj hlob ntxiv. Tam sim no, muaj amorphous, polycrystalline, thiab monocrystalline TFT-LCDs. Nyob rau hauv lub neej yav tom ntej, yuav muaj TFTs ntawm lwm yam ntaub ntawv, ob lub iav substrates thiab yas substrates.
(4) Cov cwj pwm zoo ntawm kev tiv thaiv ib puag ncig: tsis muaj hluav taws xob, tsis muaj teeb meem, tsis muaj kev puas tsuaj rau tus neeg siv kev noj qab haus huv. Qee qhov tshwm sim ntawm TFT-LCD e-phau ntawv yuav coj tib neeg mus rau hauv cov tsev kawm ntawv tsis muaj ntawv thiab tsis luam ntawv, uas yuav ua rau lub tswv yim ua rau tib neeg kawm, nthuav tawm thiab sau lawv cov kev vam meej.
(5) Feem ntau cov ntawv thov, muaj qhov kub li ntawm -20 ° C mus rau + 50 ° C. Tom qab qhov kub thiab siv zog TFT-LCD, qhov ntsuas kub tsawg khiav hauj lwm yuav ncav cuag li 80 ° C. Yuav siv tau los ua ib qho khoom dav hlau mobile, cov dav hlau dav dav dav, tab sis kuj yog rau TV loj saib TV, nws yog ib qho chaw siab kawg-kev ua yeeb yaj duab saib davhlau ya nyob twg.
(6) Tsawg tus nqi: Cov iav substrates thiab cov yas substrates nyuaj los daws qhov teeb meem ntawm cov nqi ntawm cov khoom siv loj-loj semiconductor integrated circuits, thiab qhib tau qhov chaw siab dav siv rau daim ntawv thov cov txheej txheem loj-loj semiconductor integrated circuits.
