OLED (Organic Light-Emitting Diode) yog hais txog cov organic teeb-emitting diodes, uas sawv cev rau ib yam khoom tshiab nyob rau hauv lub realm ntawm cov xov tooj ntawm tes. Tsis zoo li ib txwm LCD thev naus laus zis, OLED cov cuab yeej siv tshuab tsis xav tau lub teeb rov qab. Hloov chaw, nws siv ultra-nyias cov khoom siv coatings thiab iav substrates (los yog hloov tau yooj yim organic substrates). Thaum siv hluav taws xob tam sim no, cov khoom siv organic no tawm lub teeb. Tsis tas li ntawd, OLED cov ntxaij vab tshaus tuaj yeem ua kom sib dua thiab nyias dua, muab cov duab pom dav dua, thiab txo qis kev siv hluav taws xob. OLED kuj tau qhuas tias yog lub cim thib peb cov khoom siv thev naus laus zis. OLED cov lus qhia tsis yog tsuas yog nyias, sib zog, thiab siv zog ntau dua tab sis kuj khav theeb dua qhov ci, ua haujlwm zoo dua luminescence, thiab muaj peev xwm los tso saib cov xim dub. Tsis tas li ntawd, lawv tuaj yeem nkhaus, raws li pom nyob rau hauv niaj hnub nkhaus-screen TVs thiab smartphones. Niaj hnub no, cov tuam txhab lag luam loj thoob ntiaj teb tab tom sib tw los txhim kho R&D kev nqis peev hauv OLED cov cuab yeej thev naus laus zis, ua rau nws cov ntawv thov dav dav hauv TV, khoos phis tawj (saib), smartphones, ntsiav tshuaj, thiab lwm yam. Thaum Lub Xya Hli 2022, Apple tshaj tawm cov phiaj xwm los qhia OLED cov ntxaij vab tshaus rau nws cov kab hauv iPad nyob rau xyoo tom ntej. Cov qauv tshiab 2024 iPad yuav nthuav tawm tshiab OLED cov duab vaj huam sib luag, txheej txheem uas ua rau cov vaj huam sib luag no txawm tias nyias thiab sib dua.
Lub hauv paus ntsiab lus ua haujlwm ntawm OLED cov duab yog qhov txawv ntawm LCDs. Feem ntau tsav los ntawm hluav taws xob teb, OLEDs ua tiav lub teeb emission los ntawm kev txhaj tshuaj thiab recombination ntawm cov cab kuj nyob rau hauv cov organic semiconductor thiab luminescent cov ntaub ntawv. Cias muab, ib qho screen OLED yog tsim los ntawm ntau lab tus me me "qhov muag teev."
Ib qho khoom siv OLED feem ntau muaj xws li substrate, anode, qhov txhaj tshuaj txheej (HIL), qhov thauj txheej (HTL), electron thaiv txheej (EBL), emissive txheej (EML), qhov thaiv txheej (HBL), electron thauj txheej (ETL), electron txhaj txheej (EIL), thiab cathode. Cov txheej txheem tsim khoom ntawm OLED cov cuab yeej siv thev naus laus zis xav tau kev ua haujlwm siab heev, muab faib dav rau hauv cov txheej txheem pem hauv ntej thiab rov qab kawg. Cov txheej txheem pem hauv ntej feem ntau suav nrog cov txheej txheem photolithography thiab cov txheej txheem evaporation, thaum cov txheej txheem rov qab kawg tsom rau kev siv tshuab thiab txiav tshuab. Txawm hais tias cov thev naus laus zis OLED feem ntau yog tus txawj ntse los ntawm Samsung thiab LG, ntau lub tuam txhab suav hauv Suav kuj tseem ua kom lawv cov kev tshawb fawb ntxiv rau hauv OLED cov ntxaij vab tshaus, nce kev nqis peev hauv OLED cov lus. OLED cov khoom lag luam twb tau muab tso rau hauv lawv cov khoom. Txawm hais tias muaj qhov sib txawv tseem ceeb piv rau cov tuam txhab loj thoob ntiaj teb, cov khoom lag luam no tau mus txog qib siv tau.
