Organic Light Emitting Diode (OLED), tseem hu ua organic electroluminescent zaub, organic light-emitting semiconductor. OL Deth Qingyun ntawm lub tuam txhab Kodak nyob hauv teb chaws As Mes Lis Kas xyoo 1979. Vim tias nws qhov teeb pom kev zoo, qhov sib txawv ntawm qhov zoo, qhov sib txawv ntawm qhov dav, kev siv zog tsawg, cov lus teb ceev ceev, cov ntaub ntawv yooj yim, thiab lwm yam. pom txij thaum nws discovery. Rau lub cim tshiab ntawm cov khoom siv tshuab.
OLED organic cov ntaub ntawv yog cov khoom tseem ceeb rau OLED cov duab qhia. Raws li cov xwm txheej ntawm OLED tam sim no, daim ntawv no yuav tsom mus rau cov cuab yeej tawm thiab kev lag luam kev lag luam ntawm cov khoom organic organic.
I. Ib qho ntawm txoj kev lag luam hauv OLED
Qhov ntws ntawm OLED kev lag luam muaj xws li cov khoom siv, kev tsim khoom, thiab kev tivthaiv pawg. Qhov nruab nrab txuas nrog kev tsim vaj huam sib luag, modules, thiab tus neeg tsav tsheb chips. Tus nqes nram qab no muaj xws li ntau hom kev siv davhlau ya nyob twg.
1. OLED ntws los
Vim yog lub siab tshaj plaws, qhov kev npaj ntawm OLED ntws ua lag luam yog qhov muag ntawm cov khw muag khoom txawv teb chaws, thiab tsis muaj ntau qhov chaw lag luam uas tuaj yeem ua tau ntau yam hauv Suav teb. Hauv kev lag luam ntawm cov cuab yeej tsim, Japanese tuamyhiab Canon Tokki thiab Ulvac yog cov ua rau txoj hauv kev tseem ceeb xws li evaporation. Tam sim no, tsis muaj cov chaw tsim khoom lag luam industrialized OLED, cov khoom siv cuab yeej thiab cov khoom siv hluav taws xob. Tshuab yog nyob rau ntawm tes ntawm Japanese, Kauslim thiab European cov tuam txhab.
Tam sim no, thaj tsam ntawm OLED ntws cov ntaub ntawv yog lub ntiaj teb ntawm Nyiv, Kaus Lim Kauslim, Tebchaws Europe thiab Tebchaws Meskas, feem ntau yog nyob rau ntawm tes ntawm Japan's Idemitsu Kosan Co., Ltd. (txuas ntxiv mus "Idemitsu Kosan"), Hodogaya Chemical Industry Co., Ltd., UDC, thiab qee cov tuam txhab Kauslim Teb. Japanese thiab Kauslim tuam txhab uas muag tau tsim cov khoom me me rau cov khoom siv me me-molecule luminescent. Cov European thiab Asmeskas cov lag luam feem ntau tsim cov khoom siv luminescent nrog cov patent loj teeb meem thiab qee cov txheej txheem cov txheej txheem high-end, uas cov Japanese thiab Korean cov neeg ua lag luam rau txog 80% ntawm kev ua lag luam. Nyiv yog ib qho tseem ceeb ntawm cov khoom tuav ntawm OLED. Cov polymers uas ua los ntawm Sumitomo Chemical Co., Ltd. thiab Showa Denko Co., Ltd. yog cov ntaub ntawv yooj yim rau cov tshuab OLED. Idemitsu Kosan Co., Ltd. thiab Mitsui Chemicals Co., Ltd. yog tsim los ua cov khoom me me cov khoom me me.
OLED khoom siv rau 30% ntawm tag nrho cov nqi ntawm OLED tshuaj cov khoom, thaum nyob hauv cov khoom LCD, cov khoom siv nyiaj rau 70% ntawm tag nrho cov nqi. Tom qab kov yeej qhov teeb meem uas tsis muaj cov khoom tawm ntawm OLED, OLEDs muaj nqi txaus txo qhov chaw kom txo lawv cov nqi qis dua cov kua siv lead ua kua.
2. OLED nruab nrab
Nyob hauv nruab nrab ntawm thaj chaw, Samsung Group (txuas ntxiv mus hu ua "Samsung"), LG Pawg thiab lwm cov neeg loj tswj kev tswj ntawm qhov chaw siab kawg nruab nrab. Lub ntiaj teb huab hwm coj tsim OLED zaub thaj tsam yog Cheeb Tsam Keeb Kwm feem ntau, thiab Samsung yog tam sim no lub ntiaj teb chaw lag luam loj me me thiab nruab nrab ntawm OLED panels. LG Display (LGD) yog thawj lub hom phiaj loj rau cov koom haum loj OLEDs. Kev pom ntawm txoj kev loj hlob ntawm cov khoom me me hauv tshuab hluav taws xob, LGD maj mam hloov kho me me thiab cov nrab OLEDs.
3. OLED downstream
OLED tshuab tau maj mam ua qhov qauv zoo hauv kev nqes qaum hauv qab, thiab kev lag luam loj hlob zoo heev. Tus iPhone X siv ib qho OLED cov duab, uas coj teebmeem ua yeeb yam rau tag nrho lub xov tooj smartphone. LG, Samsung, Huawei, OPPO, TCL thiab lwm lub tuam txhab hluav taws xob thiab khoom siv hluav taws xob hluav taws xob hauv xyoo 2017 kom nce cov teebmeem ntawm cov haujlwm OLED. Tsis tas li ntawd, OLEDs tseem muaj kev loj hlob zoo hauv TV, tsheb nqaj hlau thiab tsav tsheb, cuab yeej siv tau thiab kev ua haujlwm, thiab muaj kev nthuav dav dav.
Cov cim tshiab ntawm OLEDs muaj dav zeem muag thiab muaj ntau lub rooj sib txoos txawv thiab txawv tebchaws. Feem ntau ntawm cov khoom siv sab nrauv xws li tus tsav tsheb ICs, cov yeeb yam iav, pob iav, cov khoom siv organic, qhov ncauj qhov ntswg, thiab lwm yam yuav tsum tau yuav los ntawm Nyiv, Kaus Lim qab teb thiab lwm lub teb chaws. Xwb hais lus, Tuam Tshoj tus domestic manufacturers feem ntau concentrated nyob rau hauv nruab nrab thiab qis nce mus txog ntawm lub vaj huam sib luag, modules thiab lwm yam teb.
