OLED (Organic Light-Emitting Diode) cov lus qhia sawv cev rau kev hloov pauv cov khoom siv thev naus laus zis, nrog rau lawv cov txiaj ntsig tseem ceeb nyob hauv lawv cov khoom ntiag tug, ua rau pixel-theem meej lub teeb tswj tsis tas yuav tsum muaj lub teeb pom kev zoo. Cov yam ntxwv ntawm tus yam ntxwv no muab cov txiaj ntsig zoo tshaj plaws xws li qhov sib txawv ntawm qhov sib txawv siab, nyob ze-180-degree saib cov ces kaum, thiab microsecond-theem teb lub sij hawm, thaum lawv cov ultra-nyias thiab saj zawg zog qhov ua rau lawv zoo tagnrho rau foldable npo li. Ib qho OLED cov zaub muaj ntau txheej txheej nrog rau cov substrates, electrode khaubncaws sab nraud povtseg, thiab organic functional khaubncaws sab nraud povtseg, nrog rau cov organic emissive txheej ua tiav electroluminescence los ntawm electron-qhov recombination. Kev xaiv cov khoom siv sib txawv ntawm cov organic tso cai rau cov xim emissions tunable.
Los ntawm txoj kev xav ua haujlwm, OLED qhia txog qhov txhaj tshuaj thiab cov khoom siv hluav taws xob los ntawm cov anode thiab cathode, raws li txoj cai, nrog rau cov neeg nqa khoom them nqi rov ua dua nyob rau hauv cov organic emissive txheej los tsim excitons thiab tso tawm photons. Qhov no ncaj qha lub teeb-emitting mechanism tsis tsuas yog simplifies cov qauv duab tab sis kuj ua tiav cov xim ntshiab dua. Tam sim no, thev naus laus zis tau hloov zuj zus mus rau hauv ob qho khoom siv loj: me me-molecule OLEDs thiab polymer OLEDs, nrog cov txheej txheem doping precision ntxiv txhim kho luminous efficiency thiab xim purity.
Ntawm daim ntawv thov, OLED cov cuab yeej siv tshuab tau nkag mus rau ntau qhov chaw xws li cov khoom siv hluav taws xob, tsheb, thiab cov khoom siv kho mob. High-end smartphones thiab TVs dominate lub lag luam vim lawv cov duab zoo dua, thaum lub tsheb qhia leverage lawv yooj yim mus ua kom nkhaus dashboard designs. Cov cuab yeej kho mob tau txais txiaj ntsig los ntawm lawv cov yam ntxwv zoo sib xws. Nrog rau qhov tshwm sim ntawm cov ntaub ntawv tshiab xws li pob tshab OLEDs thiab stretchable OLEDs, OLED cov cuab yeej siv tau nrawm nrawm rau hauv cov chaw tawm tshiab xws li cov tshuab hauv tsev ntse thiab qhov tseeb, ua kom pom kev loj hlob muaj peev xwm.
