LCD tau hloov CRT raws li lub ntsiab, thiab tus nqi tau poob ntau, thiab nws tau dhau los ua neeg nyiam.
Raws li cov teeb pom kev sib txawv, LCD tuaj yeem muab faib ua ob hom: CCFL thiab LED.
Kev nkag siab yuam kev:
Ntau tus neeg siv ntseeg tias cov kua siv lead ua kua tuaj yeem muab faib ua LEDs thiab LCDs.Rau qee qhov, qhov kev nkag siab no yog yuam kev los ntawm kev tshaj tawm.
LED zaub ntawm kev ua lag luam tsis yog qhov tseeb LED zaub.Yuav kom meej, nws yog LED-backlit kua siv lead ua zaub.Lub vaj huam sib luag kua siv lead ua tseem yog ib txwm siv LCD zaub.Hauv kev nkag siab, qhov no yog qee qhov kev dag ntxias.xwm!Kaus Lim Kauslim Samsung ib zaug raug txim los ntawm British Advertising Association ua txhaum lub teb chaws txoj cai tshaj tawm vim nws "LEDTV" LCD TVs tau xav tias yuav ua rau cov neeg siv khoom dag.Rau cov kua siv lead ua kua, qhov tseem ceeb tshaj plaws yog nws cov LCD vaj huam sib luag thiab cov teeb pom kev zoo, thaum lub LCD vaj huam sib luag ntawm cov khoom lag luam feem ntau siv TFT panels, uas yog tib yam.Qhov txawv ntawm LEDs thiab LCDs yog tias lawv hom teeb pom kev sib txawv: LED Lub teeb thiab CCFL backlight (uas yog, cov teeb fluorescent) yog diodes thiab txias cathode teeb, feem.
LCD yog lub ntsiab lus rau Liquid Crystal Display, uas txhais tau tias "kua siv lead ua kua", uas yog, kua siv lead ua kua.LED yog hais txog ib hom kua siv lead ua kua zaub (LCD), uas yog, cov kua siv lead ua kua (LCD) nrog LED (lub teeb emitting diode) ua lub teeb pom kev zoo.Nws tuaj yeem pom tias LCD suav nrog LEDs.Qhov sib piv ntawm LED yog tiag tiag CCFL.
Hais txog cov kua siv lead ua kua (LCD) nrog CCFL (lub teeb txias cathode fluorescent) ua lub teeb pom kev zoo.
Qhov kom zoo dua ntawm CCFL yog cov xim zoo, tab sis qhov tsis zoo yog siv zog ntau dua.
Hais txog cov kua siv lead ua kua (LCD) uas siv LEDs (lub teeb emitting diodes) ua lub teeb pom kev zoo, thiab feem ntau yog hais txog WLEDs (dawb lub teeb LEDs).
Qhov zoo ntawm LED yog qhov me me thiab siv hluav taws xob tsawg.Yog li ntawd, siv LED ua lub teeb pom kev zoo tuaj yeem ua tiav qhov ci ntsa iab thaum coj mus rau hauv tus account lightness thiab thinness.Qhov tsis zoo tseem ceeb yog qhov kev ua tau zoo ntawm cov xim tsis zoo dua li ntawm CCFL, yog li feem ntau cov duab LCDs tseem siv ib txwm siv CCFL ua lub teeb pom kev zoo.
Tus nqi qis
Feem ntau hais lus, txo cov nqi tau dhau los ua txoj cai tseem ceeb rau cov tuam txhab kom muaj sia nyob.Thoob plaws hauv keeb kwm ntawm kev loj hlob ntawm TFT-LCD, nws tsis yooj yim los nrhiav pom tias qhov loj ntawm cov iav substrates, txo tus naj npawb ntawm cov qhov ncauj qhov ntswg, nce qhov chaw nres tsheb tsim khoom thiab cov khoom lag luam tawm, thiab kev yuav khoom raw khoom nyob ze yog qhov kev siv zog tas li ntawm ntau TFT- LCD manufacturers..
iav substrate yog ib qho tseem ceeb raw khoom rau zus tau tej cov TFT-LCD, thiab nws cov nqi yog kwv yees li 15% mus rau 18% ntawm tag nrho cov nqi ntawm TFT-LCD.Nws tau tsim los ntawm thawj tiam kab (300mm × 400mm) mus rau tam sim no thib kaum tiam kab (2,850mm × 3,050).mm), nws tau dhau los ntawm lub sijhawm luv ntawm nees nkaum xyoo.Txawm li cas los xij, vim tias qhov kev xav tau siab heev rau cov tshuaj muaj pes tsawg leeg, kev ua haujlwm thiab cov txheej txheem tsim khoom ntawm TFT-LCD iav substrates, lub ntiaj teb TFT-LCD iav substrate ntau lawm tshuab thiab kev lag luam tau ntev tau siv los ntawm Corning hauv Tebchaws Meskas, Asahi iav thiab Hluav taws xob iav, thiab lwm yam Monopolized los ntawm ob peb lub tuam txhab.Raws li kev txhawb nqa kev lag luam muaj zog, thaj av loj ntawm kuv lub teb chaws kuj tau pib koom nrog R&D thiab tsim cov TFT-LCD iav substrates hauv xyoo 2007. Tam sim no, ib tug xov tooj ntawm TFT-LCD iav substrate ntau lawm kab ntawm lub thib tsib tiam thiab saum toj no tau tsim nyob rau hauv Suav teb.Nws tau npaj yuav tshaj tawm ob 8.5-tiam high-tiam kua siv lead ua iav substrate ntau lawm kab ua haujlwm nyob rau hauv ib nrab xyoo 2011.
Qhov no muab ib qho tseem ceeb lav rau lub localization ntawm upstream raw cov ntaub ntawv rau TFT-LCD manufacturers nyob rau hauv mainland kuv lub teb chaws thiab ib tug tseem ceeb txo nyob rau hauv manufacturing nqi.
Qhov tseem ceeb tshaj plaws ntawm TFT ntau lawm tshuab yog cov txheej txheem photolithography, uas tsis yog tsuas yog ib feem tseem ceeb ntawm kev txiav txim siab cov khoom zoo, tab sis kuj yog ib feem tseem ceeb uas cuam tshuam rau cov nqi khoom.Nyob rau hauv cov txheej txheem photolithography, feem ntau yog them rau lub ntsej muag.Nws qhov kev ua tau zoo txiav txim siab qhov zoo ntawm TFT-LCD mus rau qhov loj, thiab kev txo qis ntawm nws txoj kev siv tuaj yeem txo cov cuab yeej siv peev thiab txo lub voj voog ntau lawm.Nrog rau kev hloov ntawm TFT qauv thiab kev txhim kho cov txheej txheem ntau lawm, tus naj npawb ntawm qhov ncauj qhov ntswg siv hauv cov txheej txheem tsim khoom raug txo qis.Nws tuaj yeem pom tias TFT cov txheej txheem tsim tawm tau hloov zuj zus los ntawm cov txheej txheem 8-mask lossis 7-mask lithography rau tam sim no siv 5-mask lossis 4-mask lithography txheej txheem, uas txo qis TFT-LCD ntau lawm voj voog thiab cov nqi tsim khoom. .
4 Mask lithography txheej txheem tau dhau los ua qhov tseem ceeb hauv kev lag luam.Txhawm rau kom txo qis cov nqi tsim khoom tsis tu ncua, tib neeg tau sim tshawb nrhiav yuav ua li cas ntxiv txo cov npog ntsej muag siv hauv cov txheej txheem photolithography.Nyob rau hauv xyoo tas los no, qee lub tuam txhab Kaus Lim Kauslim tau ua tiav hauv kev txhim kho 3-mask lithography txheej txheem, thiab tau tshaj tawm ntau lawm.Txawm li cas los xij, vim muaj kev siv tshuab nyuaj ntawm cov txheej txheem 3-lub npog ntsej muag thiab cov txiaj ntsig qis, tseem muaj kev vam meej ntxiv.Hauv kev txhim kho thiab txhim kho.Los ntawm txoj kev loj hlob mus ntev, yog tias Inkjet (inkjet) tshuab luam ntawv ua rau muaj kev tawg, kev ua tiav ntawm kev tsim cov npog ntsej muag yog lub hom phiaj kawg uas tib neeg nrhiav.
