Sawv yog cov tsiaj ntawv luv ntawm cov organic teeb emitting teeb meem, uas txhais tau txheej txheem ntawm ob lub tswv yim thiab hluav taws xob zoo thiab tsis zoo rau cov khoom siv organic, lawv emit Lub teeb .Tus qauv qauv ntawmSawv yog ua ib txheej ntawm cov organic teeb-emitting cov khoom siv tens ntawm nanometers tuab ntawm cov txheej txheem hluav taws xob nrog kev ua haujlwm tsis zoo, tsim qauv qauv zoo li cov qhaub cij.
High Technology Ooled Zaub
Substrate (pob tshab yas, iav, ntawv ci) - lub substrate yog siv los txhawb pab oled tag nrho.
Anode (pob tshab) - lub anode tshem tawm cov tshuab hluav taws xob (nce electron "qhov") raws li tam sim no ntws los ntawm lub cuab yeej.
Cov txheej thauj - cov txheej txheej thauj - cov txheej txheej txheej txheej no ua los ntawm cov khoom siv organic molecules uas thauj khoom "qhov" ntawm anode.
Txheej txheej luminity - txheej txheej no yog ua los ntawm cov organic cov khoom siv molecules (raws li txwv tsis pub ua cov khaubncaws sab nraud povtseg yuav siv qhov chaw luminescence yuav siv qhov chaw.
Hauv hluav taws xob thauj khoom - txheej txheej txheej no ua los ntawm cov khoom siv organic molecules uas thauj khoom hluav taws xob los ntawm lub cathode.
Cathodes (uas tuaj yeem ua pob tshab los yog opaque, nyob ntawm hom OLED) - thaum tam sim no ntws los ntawm cov cuab yeej, cathodes txhaj hluav taws xob rau hauv Circuit Court.
Cov txheej txheem lumcence ntawm OLED feem ntau muaj cov theem ntawm tsib hauv qab no:
① Cov Khoom Siv Hluav Taws Xob: Hauv qab ntawm ib qho hluav taws xob sab nraud, hluav taws xob thiab cov qhov muaj zog ntawm cov tshuab hluav taws xob los ntawm cov Cathode thiab anode, feem.
② Cov Hluav Taws Xob Carrier thiab Cov Hluav Taws Xob Txhaj Tshuaj Thiab Qhov Chaw Nkag Tawm Ntawm Electron Thauj Txheej Thiab Qhov Thauj Khoom Mus Rau Lub Luminescent Txheej, feem.
③ Cov Hluav Taws Xob Kev Txhim Kho: tom qab lub tshuab hluav taws xob thiab cov qhov siv hluav taws xob, lawv tau khi rau hauv lub qhov ua ke los ua ke rau cov khoom siv hluav taws xob, uas yog, zoo siab, vim kev txiav txim ntawm Coulombor.
Might Exciton tsiv teb tsaws: vim qhov tsis txaus ntseeg ntawm hluav taws xob thiab lub qhov kev thauj khoom tseem ceeb, yog li diffusion tsiv teb tsaws chaw yuav tshwm sim vim yog cov kev tsim kho tau.
⑤exciton hluav taws xob degenerates photenation duab: ib qho kev hloov pauv radiative uas emits photons thiab tshaj tawm hluav taws xob.
