TFT-LCD membrane hloov

TFT-LCD membrane hloov

Nqe lus piav qhia luv:

LCD (luv rau Liquid Crystal Display) kua siv lead ua kua.

Cov qauv LCD yog tso cov kua siv lead ua kua nruab nrab ntawm ob lub iav sib txuas ua ke. Cov iav hauv qab qis yog nruab nrog TFT (zaj duab xis nyias zaj duab xis), thiab iav txheej sab saud tau nruab nrog cov lim xim. Lub teeb liab thiab qhov hluav taws xob ntawm TFT tau hloov pauv los tswj cov kua ua kua molecules. Tig cov lus taw qhia, txhawm rau tswj xyuas seb lub teeb pom kev zoo ntawm txhua lub ntsiab lus pixel tau tso tawm lossis tsis ua tiav lub hom phiaj ntawm cov zaub.

Nta

LCD tau hloov CRT los ua 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 faib ua ob hom: CCFL thiab LED.

Tsis nkag siab:

Ntau tus neeg siv ntseeg tias cov kua siv lead ua kua tuaj yeem 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 raug, nws yog LED-backlit kua siv lead ua zaub. Cov kua siv lead ua kua vaj huam sib luag tseem yog ib txwm tso saib LCD. Hauv qhov kev nkag siab, qhov no yog qhov dag me ntsis. xwm! Kaus Lim Qab Teb Samsung ib zaug tau raug txim los ntawm British Kev Koom Tes Kev Lag Luam raws li ua txhaum lub tebchaws txoj cai tshaj tawm vim tias nws "LEDTV" LCD TV tau xav tias ua rau cov neeg siv dag ntxias. Rau cov kua siv lead ua kua, qhov tseem ceeb tshaj plaws yog nws lub vaj huam sib luag LCD thiab hom teeb pom kev zoo, thaum lub vaj huam sib luag LCD ntawm cov khoom lag luam feem ntau siv TFT vaj huam sib luag, uas zoo ib yam. Qhov sib txawv ntawm LEDs thiab LCDs yog tias lawv lub teeb pom kev zoo sib txawv: LED Lub teeb rov qab thiab CCFL lub teeb pom kev zoo (uas yog cov teeb roj fluorescent) yog diodes thiab txias txias cathode teeb, feem.

LCD yog lub npe luv rau kua Crystal Display, uas txhais tau tias "kua siv lead ua kua", uas yog, cov kua siv lead ua kua. LED hais txog ib hom kua siv lead ua kua (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 qhov tseeb CCFL.

CCFL

Hais txog cov kua siv lead ua kua (LCD) nrog CCFL (txias cathode fluorescent teeb) ua lub teeb pom kev zoo.

Qhov zoo ntawm CCFL yog qhov ua tau zoo xim, tab sis qhov tsis zoo yog qhov siv hluav taws xob ntau dua.

TFT-LCD

LED

Hais txog cov kua siv lead ua kua (LCD) uas siv LEDs (lub teeb tso tawm lub teeb) ua lub teeb pom kev, thiab feem ntau hais txog WLEDs (lub teeb dawb 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 tuaj yeem ua tiav qhov ci ci thaum coj mus rau hauv tus account qhov pom kev thiab qhov muag. Qhov tsis zoo tseem ceeb yog qhov xim ua tau zoo dua li ntawm CCFL, yog li cov duab tshaj lij LCDs tseem siv CCFL ib txwm ua lub teeb pom kev.

Cov Kev Ntsuas

Tus nqi qis

Feem ntau hais lus, txo nqi tau dhau los ua txoj cai tseem ceeb rau cov tuam txhab kom muaj sia nyob. Thoob plaws hauv keeb kwm kev txhim kho ntawm TFT-LCD, nws tsis nyuaj kom pom tias nce qhov loj ntawm iav txheej, txo tus naj npawb ntawm lub qhov ncauj qhov ntswg, nce chaw tsim khoom hauv paus thiab cov khoom lag luam tawm los, thiab yuav cov khoom siv raw nyob ze yog kev siv tas li ntawm ntau TFT- LCD manufacturers. .

Cov iav iav yog cov khoom siv tseem ceeb rau kev tsim cov TFT-LCD, thiab nws cov nqi raug kwv yees li 15% txog 18% ntawm tag nrho tus nqi ntawm TFT-LCD. Nws tau tsim los ntawm thawj kab kab (300mm × 400mm) mus rau kab thib kaum tam sim no (2,850mm × 3,050). mm), nws tsuas yog dhau lub sijhawm luv ntawm nees nkaum xyoo. Txawm li cas los xij, vim qhov xav tau siab heev rau cov tshuaj lom neeg muaj pes tsawg leeg, ua tau zoo thiab txheej txheem txheej txheem ntawm TFT-LCD iav substrates, thoob ntiaj teb TFT-LCD iav substrate ntau lawm thev naus laus zis thiab kev lag luam tau siv ntev los ntawm Corning hauv Tebchaws Meskas, Asahi iav thiab Cov iav iav, thiab lwm yam. Raws li kev txhawb nqa kev txhim kho kev lag luam, thaj av loj ntawm kuv lub tebchaws kuj tau pib koom nrog R&D thiab tsim khoom ntawm TFT-LCD iav substrates hauv xyoo 2007. Tam sim no, tus lej ntawm TFT-LCD iav substrate cov kab ntau lawm thib tsib thiab saum toj no tau tsim nyob hauv Suav teb. Nws tau npaj yuav tshaj tawm ob lub 8.5-tiam-tiam ua kua siv lead ua kua txheej txheej txheej kab ntau lawm hauv ib nrab xyoo 2011.

Qhov no muab qhov kev lees paub tseem ceeb rau kev tsim cov khoom siv raw dej ntws rau TFT-LCD cov lag luam hauv thaj av kuv lub tebchaws thiab txo qis kev tsim nqi.

Qhov tseem ceeb tshaj plaws ntawm TFT cov thev naus laus zis yog txheej txheem photolithography, uas tsis yog tsuas yog ib feem tseem ceeb ntawm kev txiav txim siab cov khoom lag luam zoo, tab sis kuj yog ib feem tseem ceeb uas cuam tshuam rau cov nqi khoom. Hauv cov txheej txheem photolithography, kev saib xyuas ntau tshaj yog them rau daim npog ntsej muag. Nws qhov zoo txiav txim siab qhov zoo ntawm TFT-LCD mus rau qhov loj, thiab kev txo nws txoj kev siv tuaj yeem txo cov cuab yeej nqis peev thiab ua kom luv lub voj voog tsim khoom. Nrog kev hloov pauv ntawm TFT tus qauv thiab kev txhim kho cov txheej txheem tsim khoom, tus naj npawb ntawm lub qhov ncauj qhov ntswg siv hauv cov txheej txheem tsim khoom raug txo qis. Nws tuaj yeem pom tias txheej txheem txheej txheem TFT tau hloov pauv los ntawm txheej txheem txheej txheem 8-daim npog lossis 7-daim npog rau tam sim no siv 5-daim npog lossis 4-daim npog txheej txheem txheej txheej, uas txo qis TFT-LCD cov voj voog ntau lawm thiab cov nqi tsim khoom. .

4 Daim npog ntsej muag txheej txheem txheej txheem tau dhau los ua qhov tseem ceeb hauv kev lag luam. Txhawm rau txhawm rau txo tus nqi tsim khoom tsis tu ncua, tib neeg tau sim tshawb nrhiav yuav ua li cas txuas ntxiv txo tus naj npawb ntawm lub qhov ncauj qhov ntswg siv hauv txheej txheem photolithography. Xyoo tsis ntev los no, qee lub tuam txhab Kauslim tau ua tiav qhov kev txhim kho ntawm 3-daim npog ntsej muag txheej txheem txheej txheem, thiab tau tshaj tawm ntau lawm. Txawm li cas los xij, vim yog thev naus laus zis nyuaj ntawm 3-daim npog txheej txheem thiab cov txiaj ntsig qis, tseem muaj kev nce qib ntxiv. Hauv kev txhim kho thiab txhim kho. Los ntawm kev xav txog kev txhim kho mus sij hawm ntev, yog tias Inkjet (inkjet) luam ntawv thev naus laus zis ua rau muaj kev vam meej, kev paub txog kev tsim lub ntsej muag tsis yog lub hom phiaj kawg uas tib neeg nrhiav.
