LCD yakatsiva CRT seyakanyanya, uye mutengo wakaderera zvakanyanya, uye wave wakakurumbira.
Zvinoenderana neakasiyana backlight masosi, LCD inogona kukamurwa kuita marudzi maviri: CCFL uye LED.
Kusanzwisisana:
Vazhinji vashandisi vanotenda kuti mvura yekristaro inoratidzira inogona kukamurwa kuita maLED uye maLCD.Kusvika kumwero wakati, kunzwisisa uku kwakarasika nezviziviso.
Iyo LED inoratidzira pamusika haisi yechokwadi LED kuratidza.Kuti zvive chaizvo, ndeye LED-backlit liquid crystal display.Iyo liquid crystal panel ichiri yechinyakare LCD kuratidza.Neimwe nzira, uhwu hunyengeri hwakati.nature!Samsung yekuSouth Korea yakambobatwa neBritish Advertising Association nemhosva yekutyora mitemo yekushambadza munyika nekuti maTV e“LEDTV” LCD TV aifungidzirwa kuti aitsausa vatengi.Yezviratidziro zvekristaro yemvura, kiyi yakakosha ndeye LCD pani uye backlight mhando, nepo LCD mapaneru ezviratidziro pamusika anowanzo shandisa TFT mapaneru, akafanana.Musiyano uripo pakati pe LEDs neLCDs ndewekuti iwo malightlight marudzi akasiyana: LED The backlight uye CCFL backlight (kureva, fluorescent mwenje) diode uye inotonhora mwenje yecathode, zvichiteerana.
LCD ndiyo acronym yeLiquid Crystal Display, zvinoreva kuti "liquid crystal display", kureva kuti, liquid crystal display.Iyo LED inoreva rudzi rwemvura yekristaro kuratidzwa (LCD), kureva, mvura yekristaro inoratidzwa (LCD) ine LED (mwenje emitting diode) seyakajeka sosi.Zvinogona kuonekwa kuti LCD inosanganisira LEDs.Iyo yakatarisana ne LED ndeyechokwadi CCFL.
Zvinoreva kune liquid crystal display (LCD) ine CCFL (inotonhora cathode fluorescent rambi) seye backlight sosi.
Iyo mukana weCCFL yakanaka kuita kwemavara, asi iyo yakashata ndeyepamusoro mashandisiro emagetsi.
Inoreva kuratidzwa kwekristaro yemvura (LCD) inoshandisa maLED (light emitting diode) seyakavhenekera sosi, uye kazhinji inoreva maWLED (white light LEDs).
Zvakanakira zve LED idiki saizi uye yakaderera simba rekushandisa.Naizvozvo, kushandisa LED senge backlight sosi inogona kuwana kupenya kwakanyanya uchifunga nezvekureruka uye kutetepa.Chinhu chikuru chinokanganisa ndechekuti kuita kwemavara kwakaipisisa kupfuura kweCCFL, saka maLCD mazhinji emifananidzo achiri kushandisa yechinyakare CCFL senzvimbo yekumashure.
Mutengo wakaderera
Kazhinji kutaura, kuderedza mitengo kwave mutemo wakakosha kuti makambani ararame.Munhoroondo yese yebudiriro yeTFT-LCD, hazvina kuoma kuwana kuti kuwedzera saizi yegirazi substrates, kuderedza huwandu hwemamaki, kuwedzera base station kugadzirwa uye goho rechigadzirwa, uye kutenga zvigadzirwa padyo ndiko kuenderera mberi kwekuedza kwevazhinji TFT- LCD vagadziri..
Girazi substrate chinhu chakakosha pakugadzirwa kweTFT-LCD, uye mutengo wayo unotora 15% kusvika 18% yemutengo wakakwana weTFT-LCD.Yakagadzirwa kubva kumutsara wechizvarwa chekutanga (300mm × 400mm) kusvika kumutsara wechizvarwa chegumi (2,850mm × 3,050).mm), yakangopfuura nepakati penguva pfupi yemakore makumi maviri.Nekudaro, nekuda kwezvakanyanya zvinodikanwa zvekuumbwa kwemakemikari, kuita uye kugadzirwa kwemamiriro eTFT-LCD girazi substrates, yepasi rose TFT-LCD girazi substrate kugadzira tekinoroji uye musika zvakagara zvichishandiswa naCorning muUnited States, Asahi Girazi uye. Electric Glass, etc. Monopolized nemakambani mashomanana.Pasi pekusimudzirwa kwakasimba kwekusimudzirwa kwemusika, nyika yenyika yangu yakatangawo kushingaira kutora chikamu muR & D nekugadzirwa kweTFT-LCD girazi substrates muna 2007. Parizvino, nhamba yeTFT-LCD girazi substrate mitsara yekugadzira yechizvarwa chechishanu uye. pamusoro dzakavakwa muChina.Yakarongwa kuvhura maviri 8.5-chizvarwa chepamusoro-chigadzirwa chekristaro girazi substrate mutsara wekugadzira mapurojekiti muhafu yechipiri ye2011.
Izvi zvinopa vimbiso yakakosha yekumisikidzwa kwenzvimbo yepamusoro yezvigadzirwa zveTFT-LCD vagadziri munyika yangu uye kudzikiswa kukuru kwemitengo yekugadzira.
Iyo inonyanya kukosha yeTFT yekugadzira tekinoroji ndeye photolithography process, iyo isiri chikamu chakakosha chekutarisa chigadzirwa chemhando, asiwo chikamu chakakosha chinokanganisa mutengo wechigadzirwa.Muchiitiko chephotolithography, kunyanya kukoshesa kunobhadharwa kune mask.Hunhu hwayo hunotaridza kunaka kweTFT-LCD kusvika pamwero mukuru, uye kudzikiswa kwekushandiswa kwayo kunogona kunyatso kudzikisa mari yekushandisa uye kupfupisa kutenderera kwekugadzira.Nekuchinja kweTFT chimiro uye nekuvandudzwa kwemaitiro ekugadzira, huwandu hwemasks anoshandiswa mukugadzira maitiro anodzikiswa.Zvinogona kuonekwa kuti maitiro ekugadzirwa kweTFT akashanduka kubva pakatanga 8-mask kana 7-mask lithography process kusvika kune yazvino kushandiswa 5-mask kana 4-mask lithography process, iyo inoderedza zvakanyanya kutenderera kweTFT-LCD uye mutengo wekugadzira. .
4 Mask lithography process yave iyo huru muindasitiri.Kuti varambe vachidzikisira mitengo yekugadzira, vanhu vanga vachiedza kuongorora kuti vangawedzera sei kudzikisa huwandu hwemasiki anoshandiswa mukuita photolithography.Mumakore achangopfuura, mamwe makambani ekuKorea akaita budiriro mukuvandudza kweiyo 3-mask lithography process, uye akazivisa kugadzirwa kwakawanda.Nekudaro, nekuda kweiyo yakaoma tekinoroji ye3-mask process uye yakaderera goho mwero, kuchine kumwe kufambira mberi.Pasi pekuvandudzwa nekuvandudzwa.Kubva pakuona kwenguva refu yekuvandudza, kana Inkjet (inkjet) tekinoroji yekudhinda ichiita budiriro, kuzadziswa kwekugadzira maskless ndicho chinangwa chekupedzisira icho vanhu vanoteedzera.
