LG thiab Samsung yuav nqis peev txheej tsim txoj kab ua haujlwm "PSI" los ua kab lus hauv xyoo 2017. Yog tias lub hom phiaj no tau ua tiav, qhov no yuav yog ib qho tseem ceeb ntawm kev loj hlob ntawm OLED ...
Txawm li cas los, tos! Vim li cas koj ho tuaj nrog ib yam tshiab hu ua "Cov ntawv luam" OLED? Qhov no puas yog ib qho qauv tshiab? Hauv tsib xyoos dhau los, cov lus tshaj tawm "OLED" Nws tau los sai sai "tau hnov ib lub tswv yim ntev! Peb puas tseem ntseeg hais tias txoj xov xwm no? Thiab nrog cov tshiab technologies, dab tsi yog cov kab ntau thawj thiab cov kab ntau lawm tam sim no yog siv?
Muaj ntau yam teeb meem! Txawm li cas los xij, cia peb saib cov xov xwm tshaj tawm li cas: Raws li cov ntawv xov xwm hauv Kauslim, Samsung Display thiab LG Display yog npaj los ntawm cov khoom siv nrog Kateeva thiab Tokyo Electron, thiab cov khoom siv xws li Merck thiab Idemitsu Kosan tau sib koom tes los qhia inkjet luam ntawv ntawm A3 thiab M2 cov kab ntau lawm. Lub sijhawm ntawv yog xyoo 2017.
Ntawm lawv, cov Samsung A3 ntau lawm kab yog lub cim thib rau 6, lub hom phiaj yog ib qho yooj yim OLED, qhov luaj li cas ntawm txhua lub hlis tawm tswv yim substrate 15,000; LG M2 kab yog 8.5 cim kab, lub phiaj xwm khoom tsis yeem OLED, lub tshuab tam sim no yog lub teeb dawb ua xim + xim lim zaj duab xis, puv dav chav hla Across, nplai ntawm lub hli substrate yog 26,000. Samsung A3 yog lub ntiaj teb thawj zaug ntshiab flexible OLED kab, uas yog tsuas yog siv rau cov ntawv me me thiab nruab nrab xws li xov tooj ntawm tes thiab RGB cov khoom muag. LG M2 yog lub ntiaj teb thawj zaug loj kab OLED, thiab yog siv los ua cov ntawv loj loj xws li TV. --These ob kab no yog cov khoom vaj huam sib luag siab tshaj plaws vaj huam sib luag khoom vaj huam sib luag ntau lawm!
Raws li xov xwm tawm, Mitsubishi Chemical twb tau muab cov qauv ntawm "OLED khoom" rau inkjet luam ntawv rau ntau tus neeg siv sij hawm nyob rau hauv thawj ib nrab ntawm lub xyoo no; domestic TCL-coj Juhua Printing tseem kos npe printing khoom khoom nrog Merck Germany thiab lwm tus. Kev sib koom tes.
Hauv kev xaus, nws zoo li hais tias "luam ntawv" + "OLED" tau dhau los ua "cov qauv tseem ceeb" ntawm cov qauv tshiab lub qauv vaj huam sib luag tso tawm tshuab hauv thawj ib nrab xyoo. Txawm li cas los xij, kuv ntseeg tias muaj coob tus neeg muaj lus nug: Tam sim no hais tias muaj cov cuab yeej loj hauv technology OLED, vim li cas cov tshuab luam ntawv thiaj nrov? Muaj plaub yam hauv qab no:
Ua ntej tshaj tawm txhua yam, luam tawm yog txoj kev pheej yig. Tsuas yog OLED khoom xwb, siv cov txheej txheem luam ntawv dua li cov txheej txheem kev txuag ceev kom txuag tau 90%.
Qhov thib ob, txawm hais tias qhov kev xyuam sib xyaw ua kom tag nrho qhov teeb meem ntawm qhov kab ntawm 3 koob mus rau kab 8.5th, nws tsis tau paub qhov RGB triple thawj evaporation hauv loj loj. Lub 8.5-xyoo pib txheej txheem txoj kab-evaporation txheej txheem txo qhov yield ntawm RGB OLED peb xim-xim.
Qhov thib peb, ob lub txheej txheem ntawm cov hluav taws xob distillation thiab inkjet luam tawm tau muaj kev txawv txav ntawm cov yam ntxwv ntawm lub neej ntawm cov khoom OLED, thiab tom kawg yog siv cov khoom ntev hauv lub neej OLED. Lub neej tseem ceeb heev rau kev siv loj.
Plaub, kev sib txuas ntawm kev lag luam hauv vaj huam sib luag tam sim no yog saib xyuas cov kab loj loj, uas yog, cov peev tshiab tsim kab pib pib nrog lub cim thib 6, uas ua rau nws muaj qhov tsim kom muaj kev sib txig kom tsawg, "Kev tsim kho" teeb meem. Cov tshuab luam ntawv yog tsim meej rau txoj kev siv cov cim kab ua ke.
Ua ke, cov laj thawj no yog txaus los luam cov OLEDs ib qho kev sib tham ntawm hnub. Txawm li cas los xij, qhov loj tshaj plaws hauv lub tshuab luam ntawv ntawm OLEDs yog qhov sib txawv ntawm txhua qhov me me luam ntawv, thiab kev tsim cov cuab yeej rau cov khoom me me heev ntawm tus luam ntawv. Cov qub yog ib qhov kev kub ntxhov rau qhov kev luam tawm thiab kev lag luam kev lag luam, thaum kawg tom qab yog cov khoom me me thiab nruab nrab. - Los yog, rau cov ntawv luam tawm OLEDs, number case stability tsis yog qhov kawg
Cov teeb meem loj, cov cuab yeej raug thiab kev ruaj ntseg yog qhov kev xeem tiag tiag. Qhov kawg, qhov tseeb, yuav tsum tau tsim muaj tom qab tsim kom muaj kev ua qauv tsim ua ntej nws tuaj yeem daws tau los ntawm qhov haujlwm.
"Kaw qhov kev sau ntawv thiab kev ruaj ntseg ntawm kev ruaj ntseg hauv Tej Kev Xyaum Ua Haujlwm, Kev Nplig, thiab Cov Zwj Ceeb" -Qhov no yog qhov tseeb tiag hauv cov ntawv luam ntawm OLED. Qhov no kuj yog qhov teeb meem loj tshaj plaws uas Samsung, LG, Juhua Printing thiab lwm lub tuam txhab tseem tabtom sim daws.
Qhov no puas yog ib qho zoo? Yeej ib tug neeg tau nug qhov no. Txawm li cas los xij, raws li kev sib piv, cov teeb meem uas tau ntsib los ntawm kev siv tshuab hluav taws xob hauv kev tsim tawm ntawm cov loj loj OLED panels tuaj yeem ua tib zoo saib tias "qhov tseeb thiab kev ruaj ntseg." Lwm cov lus hais, tom qab luam ntawv OLEDs thiab evaporating OLEDs, qhov teeb meem tseem ceeb tom qab loj loj me me yog tib yam-leej twg yuav yeej yav tom ntej nyob ntawm seb txoj kev zoo los daws qhov teeb meem no yooj yim dua.
Muaj dua lwm cov lus, cov tshuab luam ntawv OLED luam tawm xyoo 2016, qhov tseem ceeb yuav nkag siab tias yog: OLED loj loj npaum li cas los xav txog, ces peb xaiv hloov lwm txoj kev - luam tawm OLED los sim. Txawm li cas los xij, qhov no kuj yog qhov cuam tshuam loj heev hauv cov xim TV. Raws li lub OLEDisation ntawm cov xov tooj ntawm tes, yog tsis muaj cov tshuab luam ntawv, uas yuav tsis hloov txoj kev industrialization.
"Tsis txhob muaj kev zoo siab sai dhau!" Vim tias qhov no OLED, cov neeg tau txais kev pab muab ntau cov nquab. Txij li thaum xyoo 2012, Samsung tau muab ncua sij hawm tuaj txog ntawm LG "OLED TV."
Cov laj thawj rau qhov no tsis yog cov neeg muag khoom tsis ua hauj lwm nyuaj, tab sis vim "ntau txoj hau kev" muaj kev cuam tshuam, thiab kev cov teeb meem muaj ntau dua. Kev sib xyaw ua ke ntawm cov teeb meem no tau tshwm sim los ntawm "Samsung, LG" cov lus tsis muaj tseeb.
Los ntawm kev pom kev, Samsung tus earliest kab kev hlub yog "low-temperature polysilicon, steamed, RGB OLED." Txawm li cas los, qhov tseeb yog tias qhov qis-kub polysilicon TFTs yog qhov nyuaj rau loj-qhov loj qhov me me, thiab qhov loj ntawm txoj kev ua kom ncav tsis yooj yim loj. RGB OLEDs yog loj loj, thiab nws yuav luag tsis yooj yim sua kom ua lag luam. Tom qab ntawd, Samsung tau npaj lub "laser thermal hloov" luam tawm OLED, tab sis nws tsis yog thaum kawg. Rau LG yog ntse, siv ib qho hlau oxide TFT + ib nrab dav zog + WOLED + xim xim zaj duab xis txoj kev. Qhov kev no tau los ntawm ob peb yam kev nyuaj, xws li RGB technology, thiab nws yog thawj tus neeg ua kom paub ntau yam khoom loj.
Cov kev ntsuam xyuas no, peb pom tau hais tias txoj kev tsis muaj tsheb hauv OLED tsis yooj yim: TFT ntawm iav substrate, qhov sib txawv ntawm cov khoom yooj yim substrate, kub qis polysilicon thiab hlau oxide ob txoj kev loj; OLED coated nrog ib nrab steamed, tag nrho steamed, laser thermal hloov, inkjet luam ntawv tsawg kawg yog plaub yees; qhov kawg khoom xaiv kuj muaj WOLED + xim xim zaj duab xis thiab RGB OLED ob qho loj sib txawv.
Yog li ntawd, qhov xaus yog: Muaj ntau ntau txoj hau kev xaiv, uas ua rau yus coj qhov tsis ncaj ncees lawm. Qhov no yog qhov tseem ceeb "muaj peev xwm" rau cov OLEDs uas tseem tsis tau tuaj. Yog hais tias tag nrho cov kev lag luam thiab tag nrho ntawm cov kev siv hluav taws xob tau pib npaj rau inkjet RGB OLEDs, tej zaum qhov kev lag luam tag nrho tseem yuav ceev dua.
Cov xov xwm zoo tshaj plaws rau tiam tom ntej ntawm cov vaj huam sib luag rau hauv xyoo 2016 - cov tswv lag luam yeej ntseeg tias "inkjet luam ntawv" yog qhov tseem ceeb tshaj plaws rau txoj hauv kev, txawm tias tseem yuav siv cov QLEDs electroluminescent. Cov cuab yeej siv no yog siv los ntawm Samsung mus rau "rov qab OLED" technology. Txhua tus yuav tsum tau raws li qhov "inkjet printing" process. Thaum cov OLED, QLED kev lag luam, qhov kev pom zoo no ntawm cov "inkjet printing," ces OLED acceleration yuav tau.
"Txawm hais tias qhov teeb meem loj dua", "kev lag luam muaj ib qho kev pom zoo uas tsis muaj kev pom zoo" thiab ib qho kev nthuav dav rau sawvdaws, thiab ntau xyoo dhau los ntawm kev lag luam kev ua haujlwm tau ua lwm yam tseem ceeb xws li OLED khoom, ink formulations, thiab TFT txheej txheem "heev mature ". Qhov no yog qhov xov zoo tshaj rau cov lag luam OLED.
Ntawm no, tsab xov xwm pib xaus, tab sis thawj lo lus nug tseem xav tau ntxiv: Cov Printed OLEDs tuaj, yuav ua li cas nrog cov kab uas twb muaj lawm thiab hauv txoj kab tsim kho?
Ua ntej txhua yam, me me thiab nruab nrab qhov xov hlau tsis tas yuav raug xa mus rau hauv cov txheej txheem luam ntawv. Lub zog siv tam sim no siv heev. Lub tuam tsev yuav siv txuas ntxiv mus. Secondly, nyob rau hauv kev tsim kho ntawm cov kab ntau lawm, cov xaim loj loj tsuas yog kab 9 ntawm LG. Cov kab no yuav ua kom ntau xyoo los ntawm 2018, uas yog, nws txoj kev siv technologymap tuaj yeem pom tseeb tom qab OLED raug luam tawm ntawm M2 kab hauv xyoo 2017. Peb, lwm cov kab me me thiab nruab nrab hauv kev tsim kho yuav ncav tau cov lus siv ua qauv qhia ntawm LG thiab Samsung. Qeb plaub, cov teeb meem hauv cov kab ntawm OLED los ntawm cov evaporating cov kab hauv OLED tsis yog loj heev, feem ntau vim yog cov nqi. Thib tsib, cov kab loj uas loj OLED uas tau ua cov khoom loj yog cov LG's M1 thiab M2 xwb. Nplai ntawm ob kab yog tsis loj. Tus nqi ntawm kev hloov mus rau hauv kab luam ntawv yog qhov siv tau.
Yog li no, tsis muaj kev txhawj xeeb rau cov kev cuam tshuam ntawm kev siv tshuab tshiab ntawm cov kab uas twb muaj lawm. Vim tias ua ntej no OLED yeej tsis mus deb, txawm tias lawv rov los thiab taug kev dua, nws tsis yog ib qho teeb meem loj. Tsis tas li ntawd, qhov feem cuam ntawm cov khoom siv evaporating hauv cov khoom vaj khoom tsev OLED yog tsawg dua 30%.
