Kev hloov pauv ntawm OLED cov ntxaij vab tshaus

OLED (Organic Light-Emitting Diode) yog hais txog cov organic light-emitting diodes, uas sawv cev rau cov khoom tshiab hauv lub ntiaj teb ntawm cov xov tooj ntawm tes. Tsis zoo li cov thev naus laus zis LCD ib txwm muaj, OLED cov thev naus laus zis tso saib tsis xav tau lub teeb pom kev zoo. Hloov chaw, nws siv cov khoom siv organic ultra-thin thiab cov iav substrates (lossis cov organic substrates uas yooj ywm). Thaum siv hluav taws xob, cov khoom siv organic no tso tawm lub teeb. Ntxiv mus, cov ntxaij vab tshaus OLED tuaj yeem ua kom sib dua thiab nyias dua, muab cov ces kaum pom dav dua, thiab txo qis kev siv hluav taws xob. OLED kuj tseem raug hu ua thev naus laus zis tso saib tiam thib peb. Cov ntxaij vab tshaus OLED tsis yog tsuas yog nyias dua, sib dua, thiab txuag hluav taws xob ntau dua tab sis kuj muaj qhov ci ntsa iab dua, kev ua haujlwm zoo dua, thiab lub peev xwm tso saib cov xim dub ntshiab. Ntxiv mus, lawv tuaj yeem nkhaus, raws li pom hauv cov TVs nkhaus niaj hnub thiab cov xov tooj ntse. Niaj hnub no, cov chaw tsim khoom loj thoob ntiaj teb tab tom sib tw kom nce kev nqis peev R&D hauv OLED cov thev naus laus zis tso saib, ua rau nws siv dav dua hauv TVs, khoos phis tawj (saib), xov tooj ntse, ntsiav tshuaj, thiab lwm yam teb. Thaum Lub Xya Hli 2022, Apple tshaj tawm cov phiaj xwm los qhia cov ntxaij vab tshaus OLED rau nws cov kab iPad hauv xyoo tom ntej. Cov qauv iPad xyoo 2024 uas yuav los txog no yuav muaj cov vaj huam sib luag OLED tshiab uas tsim tshiab, uas yog ib qho txheej txheem uas ua rau cov vaj huam sib luag no nyias dua thiab sib dua.

Lub hauv paus ntsiab lus ua haujlwm ntawm OLED cov zaub yog qhov txawv ntawm LCDs. Feem ntau tsav los ntawm lub zog hluav taws xob, OLEDs ua tiav lub teeb ci los ntawm kev txhaj tshuaj thiab kev sib xyaw ua ke ntawm cov neeg nqa khoom hauv cov khoom siv semiconductor thiab luminescent. Hauv lwm lo lus, OLED screen yog tsim los ntawm ntau lab lub "teeb ​​me me."

Ib lub cuab yeej OLED feem ntau muaj cov substrate, anode, hole injection layer (HIL), hole transport layer (HTL), electron blocking layer (EBL), emissive layer (EML), hole blocking layer (HBL), electron transport layer (ETL), electron injection layer (EIL), thiab cathode. Cov txheej txheem tsim khoom ntawm OLED zaub technology xav tau kev txawj ntse siab heev, faib ua cov txheej txheem pem hauv ntej thiab tom qab. Cov txheej txheem pem hauv ntej feem ntau yog photolithography thiab evaporation techniques, thaum cov txheej txheem back-end tsom mus rau encapsulation thiab cutting technologies. Txawm hais tias cov thev naus laus zis OLED siab heev feem ntau yog Samsung thiab LG ua tus tswv, ntau lub tuam txhab tsim khoom hauv Suav teb kuj tseem tab tom ua kom lawv txoj kev tshawb fawb ntxiv rau hauv OLED screens, ua rau kev nqis peev ntau ntxiv rau OLED screens. Cov khoom OLED zaub twb tau koom ua ke rau hauv lawv cov khoom muag. Txawm hais tias muaj qhov sib txawv loj piv rau cov tuam txhab loj thoob ntiaj teb, cov khoom no tau mus txog qib siv tau.
