Cov Khoom Siv Ntau Lawm Ntawm OLED

Mar 19, 2018

OLED Nqaij (mainstream) cov khoom siv technology

Cov txheej txheem evaporation

Ua ntej tshaj plaws, kom to taub cov cuab yeej ntawm evaporation, qhov no yuav tsum tau raug qhia los ntawm tus qauv ntawm OLED. Raws li pom hauv qab no, yog cov qauv ntawm luminescent ntawm ITO iav ua los ntawm ib txheej ntawm kaum tawm ntawm nanometers tuab, ITO pob tshab electrode thiab hlau electrode ua tus anode thiab cathode electrode ntaus voltage, hauv qee qhov voltage, electrons thiab qhov yog cov cathode thiab anode mus rau hluav taws xob thiab electron thiab qhov kev thauj cov txheej txheem los ntawm qhov yog electron thiab qhov thauj txheej txheej nraim rau lub teeb-emitting txheej, thiab cov kab sib ntsib hauv lub teeb emitting txheej, thiab cov exciton luminescence molecular excitation, lub tom kawg ntawm ntxig tshav kub thiab ua kom pom lub teeb. Lub teeb ci ntsa iab tuaj yeem tau pom ntawm ib sab ntawm ITO, thiab cov hlau electrode zaj duab xis kuj ua raws li cov txheej txheem.


Ntawm chav kawm, cov qauv no yog ntau yam nyuab, nrog rau qhov kev xav tau kev sib cais, cov txheej txheem insulating, thiab ntxiv rau, rau tag nrho cov vaj huam sib luag. AMOLED kuj muaj TFT backplane, uas tswj txhua pixel hloov.


  

Schematic daim duab ntawm OLED pixel qauv


Tsuas hais lus, evaporation yog evaporation ntawm cov ntaub ntawv mus rau hauv atoms los yog molecules los ntawm cua sov cua kub los ntawm cua sov tam sim no, hluav taws xob nqaj bombardment, cua sov thiab cua sov. Lawv yuav ua raws li kev tawm suab ncaj qha nrog ntau qhov loj, thiab tsim daim ntawv nyias nyias nyob ntawm qhov substrate.


Cov khoom siv cuab yeej rau kev ua vaj tse ntawm OLED los ntawm evaporation tshuab yog evaporating tshuab, thiab cov cuab yeej yog nyob rau hauv sab ntws ntawm vaj huam sib luag tsim lag luam. Lub ntsiab lag luam yog Canon's Canon Tokki Enterprise. Raws li lub ntiaj teb OLED lag luam surged, Tokki lub tuam txhab tseem tsim tsim peev ntau lawm, tab sis tseem nyuaj rau cov kev xav tau ntawm cov neeg muas zaub. Nws yog hais tias lub peev xwm ntawm Tokki evaporating tshuab yog tseem ob peb zaug ib xyoos. Piv txwv, LG Display tau poob qhov kev txiav txim ntawm cov kua los vim tsawg ntawm cov cav ntoo evaporating.


Kev luam tawm tshuab

OLED npo txhua pixel "teeb teeb" ntxiv nrog rau kev khau, tab sis tseem tuaj yeem xaiv "sau" tawm. Lub inkjet luam ntawv yog siv ua piv txwv. Lub inkjet lub tshuab luam ntawv yog muab tshuaj pleev xim rau ntawm daim ntawv, yog li qhia ib phau ntawv lossis duab. Cov ntaub ntawv luam tawm yog cov khoom siv hlau uas siv cov txheej txheem luam tawm los tsim cov duab. Nws yog ib txoj hau kev. Tom qab luam ntawv thiab tso tawm, ntau cov panels tau muab luam tawm. Yog tias "tshuaj tsuag" yog OLED cov khoom, uas yog lub vaj huam sib luag ntawm OLED. "Sprayed" yog cov khoom quantum dot, uas yog lub vaj huam sib luag quantum dot. Sau cov ntawv OLED, tsuas yog hais tias, muaj ntau lub tshuab luam ntawv taub inkjet luam tawm, cov xim sib txawv ntawm polymer light-emitting khoom tso rau hauv kev sib xyaw cuab yig sab hauv nplhaib ITO iav substrate, nyias tom qab hnyav evaporation yuav tsim tau 100 nanometers hauv thickness, ib lub luminous pixel.

  

Vim li cas thiaj luam ntawv thiab tso tawm tshuab cov cim ntxiv ntawm cov qauv kev nthuav qhia? Lub tshuab nqus tsev evaporation yog tsuas siv los ntawm cov cuab yeej thiab cov tshuab, yog li nws yog qhov yooj yim tsim fabricate loj loj daim npog ntsej muag, uas ua rau cov tshuab no tuaj yeem tsis siv rau kev siv ntawm cov kab loj loj. Nyob rau hauv tus txheej txheem ntawm evaporation, cov organic khoom roj tsis tso rau hauv iav substrate, uas ua rau lub tsawg siv ntawm cov khoom. Tej zaum vim hais tias nws tsis xav tau lub tshuab evaporation chamber, tsis xav tau lub ntsej muag hlau lub ntsej muag, tsis tas yuav xim xim thiab hais txog, Matsushita hauv 2013 CES qhia tau tias, cov yeeb yam thiab kev tshawb nrhiav thiab kev siv tshuab luam ntawv, lawv hais tias yog lub ntiaj teb coob 4K OLED TV (56 nti).


Dab tsi yog qhov zoo ntawm OLED luam tawm kev sib tw rau qhov kev ua lag luam ntawm cov khoom nyhav dhau los no? Thawj yog tus nqi pheej yig, hauv kev siv raw khoom ntawm OLED vaj huam sib luag, OLED luam tawm dua evaporation tshuab txuag 90%; luam tawm OLED tshuab muaj peev xwm ua kom zoo dua qub txog lub neej khoom; cov txheej txheem ntawm inkjet luam ntawv kom yooj yim hloov mus rau cov kev xav tau ntawm cov pawg neeg txiav txim siab tshaj qhov txheej txheem evaporation, uas yog ntau txoj kab rau siab tiam ua cov loj loj substrate kev.


Raws li qhov kev taw qhia ntawm kev lag luam, qhov loj tshaj plaws bottleneck ntawm luam ntawv OLED lus dag nyob rau hauv kev tswj tsis sib xws ntawm txhua tus me me printing point (txo qhov sib txawv ntawm pixels), thiab rau kev txhim kho cov khoom pixel luam (txhim kho cov cuab yeej ntawm cov khoom). Lub qub yog qhov tseem ceeb bottleneck ntawm tag nrho cov luam ntawv thiab tso kev lag luam, thaum tom kawg yog ib qho teeb meem rau cov khoom me me thiab nruab nrab cov khoom. Los yog, kev luam ntawv OLED, qhov ruaj ntseg ntawm tus cwj mem tsis yog qhov teeb meem qhov kawg, thiab qhov tseeb thiab kev ruaj ntseg ntawm cov cuab yeej yog qhov kev xeem tiag tiag. Qhov teeb meem no yuav tsum tau muaj qhov tseeb tiag los ntawm kev lag luam tom qab tsim kom muaj kev ua qauv zoo heev.


Tuam Tshoj Huaxing Photoelectric joint multimedia luam tawm thiab tso saib cov khoom xoom hauv kev lag luam, ua ke tsim thawj lub teb chaws tshuab luam ntawv thiab cov cuab yeej technology innovation Alliance ", tsim cov luam ntawv thiab yoog kom pom cov kev pabcuam pej xeem cov chaw haujlwm thiab cov Guangdong poly Hua printing zaub technology Co. ib qho chaw ua haujlwm hauv chaw ua haujlwm.



Sab saum toj theem "ncu khoom" txoj kev hais los saum no tsuas yog siv nyob rau hauv lub ntsej muag OLED ntawm RGB trichromatic kev kho me ntsis. Samsung ntau lub TV hauv TV yog raws li cov qauv no, cov nyhuv yog qhov zoo, peb cov xim primordial yog ntshiab heev, tab sis tus nqi yog siab heev. Cov tshuab siv hauv hom evaporation no hu ua FMM, lub nplhaib zoo nkauj. Thaum evaporating, kom paub qhov txawv pixels thiab npog lub npog ncauj, qhov teeb meem sib dhos thiab lub npog ntsej muag khoom nws tus kheej yuav yog kev nyuaj.


Qhov tseeb, human beings thiaj li tswj tau tus nqi, ntau tshaj li cov TV hauv OLED, muaj xim xiav hloov xim +: qhov tswv yim no yuav tsum tsuas yog evaporation ntawm xiav OLED, cov txheej txheej hloov dua siab tshiab yuav hloov mus rau RGB xim lub teeb, qhov kev siv tshuab zoo li no yog qhov kev hloov xim xim tsis yog loj tsis muaj kev txwv.


Muaj cov chav kawm ntawm OLED TV yog peb xim xim dawb, txujci thiab LCD LCD vaj huam sib luag yog me ntsis zoo ib yam li cov xim dawb, ntxiv xim lim - ua li no raug nqi obviously npaum li cas. LG yuav tsum tau muaj cov TV, OLED, cov xim dawb, thiab ib lub tswv yim OLED twb tau muag lawm. Tsuas yog cov lim, qhov kev xa duab ntawm lub teeb xim purity yog teeb meem ntau dua, yog li qhov ci ntsa iab, qhov sib txawv, xim, lub zog txuag kev ua haujlwm hauv kev xav tsawg dua RGB OLED.
