Txij xyoo 1970 los ntawm lub ntiaj teb thawj kev siv lub LCD screen ntawm handheld calculator - cov khoom lag luam muag txij li thaum yug hauv LCD LCD npo tau ua haujlwm rau 40 xyoo nyob rau hauv tus neeg siv khoom "kev tshuaj ntsuam" ntawm kev ua lag luam, tab tom nrhiav ib lub successor.

Qhov loj me me zoo nkaus li yog qhov kev txhawj xeeb tshaj plaws. Piv rau ib tus loj loj, uas daim duab yuav tsim tau ib lub siab ntawm ib puag ncig, ze rau cov neeg pom kev pom ntawm lub TV yuav nrov dua, tsawg kawg hauv TV tub luam txaus siab ua qhov no.

Thaum xyoo 2013 Berlin cov khoom siv hluav taws xob qhia IFA, uas tau xaus rau lub Cuaj Hli Ntuj, Samsung thiab LG tau qhia tawm qhov kev ntsuam xyuas TV no. Thaum nyob rau hauv Kauslim, cov khoom no nyob rau lub rau hli ntuj tau muag. Qhov feem ntau ntawm cov npo LCD tsis muaj cov khoom siv no, thiab lub npe ntawm cov ntawv tshiab yuav txawv li lub TV LCD uas neeg pom ib lub vijtsam ntsej muag: OLED.

Nws yog lub npe ntawm Organic Electro Luminescence, thiab electroluminescence yog lub cev tshwm sim thaum lub sij hawm tam sim no los ntawm ib yam khoom los yog cov khoom no hauv ib qho hluav taws xob muaj zog. Cov neeg tshawb xyuas ua cov khoom siv organic semiconductor rau ntawm lub vaj huam sib luag glow thiab tom qab ntawd ua cov duab OLED.

Cov kws paub hauj lwm ntawm Taiwan cov tswv yim ua haujlwm AU Optronics piav qhia tias OLED npo muaj cov yam ntxwv ntawm nws tus kheej luminous, tsis xav tau ib lub teeb nrig li LCD LCD npo, yog li nws muaj tsawg zog noj, sib zog ntim, siab zoo, thiab tsis muaj tus npo LCD hauv lub qhov muag pom thiab kev ua haujlwm ntawm qhov teeb meem.

Qhov tseeb, thaum ntxov li 2007, SONY tau tsim lub ntiaj teb thawj OLED TV XEL-1. Nws cov tuab tsuas yog 3 millimeters, qhov sib piv yog siab li 1 lab: 1, qhov lus teb yog 1000 zaus ntawm LCD TV. Qhov teeb meem tsuas yog tias nws tsuas yog 11 ntiv xwb.

"Cov neeg ua haujlwm ntawm AUO tau hais tias qhov no yog kev lag luam txij li thaum yug hauv OLED cov khoom, tau sim los daws qhov teeb meem." Ob peb xyoo tom qab 2007, SONY, Samsung, LG thiab lwm lub tuam txhab tau qhib muaj 20 nti OLED TV, tab sis tseem tsis tau paub qhov khoom loj ntawm cov khoom.

Ua ntej lub advent ntawm OLED, LED qhov screen yog ib qho kev xaiv zoo tshaj plaws rau kev lag luam los hloov LCD npo. LED zaub yog tsim los ntawm ib pawg ntawm lub teeb emitting diode teem caij, txawm tias yuav ua thinner dua LCD LCD npo, tab sis nws tsis tau sib nrauj los ntawm qhov teeb pom kev zoo, thiab hauv kev sib piv, sib hla ceev, nplua nuj xim thiab lwm yam. ib qho zoo dua.

OLED yog ib yam khoom tsim los ntawm txoj cai ntawm LED technology. Nws tseem siv cov duab tso tawm ntawm lub teeb tawm, tsis txhob hloov cov khoom luminescent nrog cov hlau rau cov organic teeb meem. Qhov tshwm sim ntawm OLED tseem yog thawj qhov kev cuam tshuam ntawm OLED technology. Nws yog qhov screen OLED uas muaj peev xwm paub ntau lawm. Tab sis thaum ntxov OLED tseem muaj cov kev txwv hauv kev luminous efficiency thiab pom tau hais tias cov npo me me - qhov ntau thiab tsawg ntawm daim phiajcim thawj OLED TV tsis tshua muaj ntau tshaj 50 ntiv.

Tab sis technicians pom lub teeb ntawm no tsawg kawg. Pib nrog OLED, OLED tau ua kom muaj kev vam meej tiag tiag los nrhiav kev lag luam ntau yam khoom siv hluav taws xob-emitting.

Sawv ntsug hauv lub kaum ntse ntse ntawm LG, LG Display, ntiaj teb li cas tus lwm thawj vice president Li Tinghan hais tias ua ntej vim nws tsis yooj yim rau cov ntsiab lus loj OLED npo xim OLED screen technology, LG tau nyuaj ua kom paub ntau ntau lawm, tau tsim mus rau LG WRGB OLED tshuab.

WRGB yog thawj daim ntawv ua ke ntawm plaub xim qauv: dawb, liab, ntsuab thiab xiav. Cov tshuaj OLED tshuaj yog xim ntsuab, xim ntsuab thiab xiav organic, thiab LG ntxiv tshiab cov organic teeb meem, thiab cia nws tawm ntawm lub substrate los ntawm xim lim zaj duab xis, thaum kawg qhia xim. Cov tshuab no siv cov teeb meem ntawm kev pab cuam luv luv rau lub neej thiab xim sib txawv ntawm cov xiav organic txuas rau cov qauv RGB, thiab realizes cov huab hwm coj ntau ntawm cov loj OLED thiab pab txoj kev ua haujlwm ntau lawm.

Qhov no yog thawj zaug uas OLED lub tshuab tau pom dua li 50 tawm xyoo. Ib txoj kev tshawb hauv xyoo 1960 pom tau hais tias xiav lub teeb yuav raug pom tom kawg ntawm anthracene wafer nrog DC voltage ntawm 400V. Anthracene yog ib qho chaw muaj organic nrog cov yam ntxwv ntawm cov cim hluav taws xob. Txij thaum ntawd los, ntau cov kws tshawb fawb tau mob siab rau lawv tus kheej rau qhov teeb meem, tiam sis tsis muaj peev xwm daws tau qhov teeb meem ntawm kev kub nyhiab, tsis tshua kaj siab thiab kev ua kom tsawg. Mus txog 1987, Kodak ob tug kws kho mob tau xaiv cov ntaub ntawv tshiab thiab cov qauv tshiab los tsim ultra-thin organic teeb emitting diodes nrog tsav tsheb deb ntawm 10V. Nyob rau hauv 2009, Kodak muag lag luam rau OLED rau LG pab pawg.

Niaj hnub no, nyob rau hauv cov lag luam ceev ceev ntawm OLED tom qab South Korea lub tuam txhab ntawm Japanese tuam txhab, xws li SONY, Matsushita, ntxiv rau kom nrhiav tau ntau cov kev daws teeb meem hauv cov khoom siv sab nraud, kuj sim ua kom pom tshiab hauv cov qauv khoom. Matsushita nyob rau lub Tsib Hlis xyoo no tau tso tawm "kev tsim lub teeb nrawm", lub teeb-emitting txheej khoom txais kev kho tshiab, lub kaum ntse ntse faib ze rau qhov yooj yim tshaj plaws kom muab lub kaum sab xis ntawm lub teeb, lub tuam txhab cov neeg pab leg ntaubntawv los ntawm txoj kev ntawm lub teeb tawm extraction yog paub txog 50%.

Adachi Chinamiya, xibfwb nyob rau hauv Kyushu University hauv Nyij Pooj, tau txais kev qhuas hauv kev lag luam hauv ob lub xyoo dhau los. Raws li Nikkei technology online lub website, lub Nikkei lub tsab ntawv ceeb toom, lub tam sim no vector vector tau nyob rau hauv txoj kev tshawb pom pom hais tias qhov kev luminous efficiency thiab cov pawg neeg phosphorescent cov khoom siv tab sis qis dua tus nqi ntawm cov khoom tshiab, yog saib raws li OLED hauv lub tshav pob ntawm "peb tiam ntawm luminescent material group".

Qhov tsis txaus ntawm no ua rau OLED npo tuav txaus kom zoo dua nyob rau hauv pem hauv ntej ntawm LCD LCD npo. Muaj lwm yam yog vim li cas cov vaj huam sib luag tau txiav txim siab los tsim qhov kev siv tshuab tshiab rau ntawm ib qho loj loj, uas yog, ua kom muag, ntxig ntxig.

Cov ntxaij lim dej yooj yim cia cov khoom siv kom muaj ntau yam kev siv. Txuas ntxiv rau cov ntawv xov xwm hauv xov tooj cua, nws tseem muaj xws li yooj yim ntse tes, ntse watches, thiab lwm yam. Slim zaub yog tam sim no tsis yog muag li daim ntawv yuav muab tais ua kom tiav, tab sis tuaj yeem tsim cuab yeej khoom siv hluav taws xob ntau lub teeb, thaum koj ua poob ntawd rau hauv av , lub vijtsam yuav tawg yog yuav txo qhov kev pheej hmoo ntawm. Siv ib lub vaj huam sib luag yooj yim OLED nyuam qhuav qhia los ntawm SHARP thiab Nyiv Semiconductor zog tshawb nrhiav chaw ua piv txwv. Lub vaj huam sib luag nrog ib thaj tsam ntawm 3.4 nti yog qis tshaj 0.1 millimeters hauv tuab thiab hnyav tsuas yog 2 grams.

Nyob ib ncig ntawm qhov "yuav ua li cas thiaj ua rau lub vijtsam ntsej muag" kev sib tw rau ntawm cov khoom siv thiab cov tshuab ua haujlwm.

Tam sim no, feem ntau paub tab substrate cov khoom tseem yog yas. Txawm li cas los xij, nyob rau hauv cov kab LCD kos kab, LCD panels feem ntau yuav tsum tau nqa tawm ntawm qhov kub siab tshaj 200 degrees, thaum cov yas substrate muaj cua sov tsis txaus, uas feem ntau tsis tuaj yeem tiv taus xws li kub.

LG Display Mobile / OLED lag luam lwm tus thawj tswj hwm President Lv Xiangde tau nkag mus rau "thawj Economy & nyiaj txiag txhua lub limtiam", LG tau ntsej muag siv cov cuab yeej txwm technology hauv ib lub yas substrate hauv tshuab technology, qhov kub txog li 350 ° C, lub kaum sab xis qaum yuav ua tau yooj yim npo.

Toshiba Co kuj tau ua qhov kev ua haujlwm hauv cov khoom siv yas ua cov yas siv. Lub tuam txhab tau nthuav tawm nws cov khoom siv ywj pheej hauv xyoo 2010, txog 8.4 nti nyob rau hauv qhov loj thiab li ntawm 0.1 hli hauv tuab. Tus neeg siv tau tuav thiab tswj tau cov tshuab loj lossis txo qhov Google Earth npo los ntawm dabtsi yog khoov. Toshiba txhim kho txuj kev siv technology ntau xyoo. Los ntawm kev ua cov oxides hauv cov txheej txheem ntawm cov khoom, qhov siab tshaj plaws yog tshuaj nyob ntawm 200 degrees centigrade.

Vim hais tias ntawm OLED screen rau tej yam khoom siv, cov kev pab cuam yuav tsum tau, lub vaj huam sib luag loj cov lag luam thoob ntiaj teb tab tom pib koom nrog lawv, ntawm chav kawm LCD cov teeb meem ntawm loj losses, coj nyiaj lag luam tshiab yog ib qhov tseem ceeb tseem ceeb.

Piv nrog rau cov txheej txheem LCD tsim ntau txheej txheem, cov txheej txheem ntawm OLED yuav ua tau yooj yim dua, tsuas yog them los ntawm ib txheej ntawm zaj duab xis transistor rau ntawm substrate (TFT) txheej, xim lim txheej, OLED luminous zaj duab xis txheej rau kab. Tab sis vim tias tus txheej txheem ntau dua, tus nqi ntawm OLED TVs yog tam sim no thiaj li hais tias cov neeg zoo tibsi ntshai: Samsung 55 nti OLED TV muag tus nqi muag khoom ntawm kwv yees li ntawm 1500 lab yeej, sib npaug RMB 8.45 lab yuan, muaj sib npaug ntawm cov nqi tsheb compact, qhov no tsis yog ib qho nrov LCD TV tus neeg siv yuav xav txog cov khoom.

Yuav kom taug qab Kauslim Kauslim Teb Chaws Nres ntawm cov khoom siv TV, SONY thiab Panasonic tau koom nrog lub koom haum OLED technology hauv xyoo 2012 thiab sib koom tes hauv txoj kev tsim khoom. SONY technology yuav ua rau cov khoom siv roj los ntawm cov cua sov siab "cua tshuab ntawm qhov substrate, thaum Matsushita tab tom tsim cov cuab yeej ua hluav taws xob tuaj yeem yog cov khoom ci tawm" luam tawm "ntawm lub vaj huam sib luag, uas yuav tsum txo tus nqi tsim ntawm OLED npo.

Yog tias peb ntxiv daws qhov teebmeem ntawm kev ua haujlwm zoo thiab tus nqi txiav txim los ntawm cov khoom siv, OLED yuav ua rau ntau qhov teebmeem hauv LCD vaj tse. Raws li cov txheeb cais ntawm txoj kev lag luam, qhov nruab nrab luminous efficiency ntawm cov khoom LED yog li 110lm / W (LM / W), thiab cov khoom zoo tshaj luminous cov khoom ntawm OLED yog 60lm / W xwb; ntawm tib qho loj ntawm cov teeb pom kev zoo, LED technology nqi txog $ 5, OLED yuav nce mus txog $ 350.

Cov ntaub ntawv yooj yim OLED hauv cov txheej txheem ntau lawm tseem muaj qee cov teeb meem, xws li yuav daws qhov kev sib cais ntawm cov dej ua pa thiab cov pa oxygen; tsis tas li ntawd yog tias qhov kev tshuaj ntsuam xav tau ntau lub duav uas yooj yim, cov tshuaj reagate zoo dua li cov yas substrate, tiam sis kev rho tawm ntawm cov hluav taws xob tsis yog mus txog qhov yuav tsum tau, thiab tus nqi kim heev thiab tshwj xeeb.

Cov lus tshawb fawb pom tias qhov kev lag luam hauv TV loj loj yuav nce ntxiv hauv 2014, thiab qhov kev lag luam yuav nce mus txog 3 billion USD los ntawm 2015. Tab sis lub koom haum kuj qhia nyob rau hauv daim ntawv tshaj tawm, kom txog thaum 2015, 4K LCD TV yuav tshaj 2 tawm ntawm TV , qhov tseem ceeb yog vim tias cov TV hauv TV OLED lub sijhawm ncua ntev, cov tuam txhab cia siab txuas ntxiv rau qhov kev nce qib ntawm 4K LCD TV.

Tam sim no tsuas yog LG Display coj mus rau ib qho kev mus kom ze. Lub tuam txhab tau txiav txim siab los nqis peev txog ntawm $ 650 lab los tsim cov 8,5 cim OLED TV vaj huam sib luag rau kab muag khoom, uas yuav tsum tau nyob rau hauv ntau ntau tshaj plaws nyob rau hauv thawj ib nrab ntawm 2014, nrog ib lub hlis twg ntawm 26 txhiab.

OLED screen tom qab tag nrho LCD LCD npo qhia tau dav dav daim ntawv thov: nws qhov kev ua haujlwm xim, teb qhov ceev thiab qhov sib txawv tshaj li cov kua siv lead ua kua yog qhov yooj yim kom paub qhov tsim zoo; nyob rau hauv raws li tib neeg cov yam ntxwv thiab khoom cov khoom muaj peev xwm raug to taub; muag pob tshab tsim, tab sis kuj yog qhov zoo tshaj plaws ntawm cov cuab yeej uas muaj kev sib ncawg zog, kuj tseem muaj kev sib txuas kov sensor duab sensor, microphone.

Tam sim no, txoj kev ua ntej ntawm lub LCD vaj huam sib luag ua tau tseeb: lub tuam txhab uas tau ua rau cov kev ua haujlwm hauv cov ntaub ntawv luminescent, substrate technology thiab cov nqi tsim nqi yuav tuav tau tus yuam sij rau lub ntsiab lus ntawm kev sib tw ntawm cov khoom sib tw. Txij thaum ntxov los yog tom qab thiab cov kua siv lead ua kua los hais lus zoo, qhov mob kuj yog kev xaiv zoo.
