OLED yog lub ntsiab lus ntawm Organic Light Emitting Diode, uas txhais tau hais tias "Organic Light Emitting display technology" hauv Suav.Lub tswv yim yog tias cov organic teeb-emitting txheej yog sandwiched ntawm ob electrodes.Thaum zoo thiab tsis zoo electrons ntsib nyob rau hauv cov khoom organic, lawv emit. lub teeb.Cov qauv yooj yim ntawmOLED yog ua ib txheej ntawm cov organic teeb-emitting cov ntaub ntawv kaum ntawm nanometers tuab ntawm indium tin oxide (ITO) iav ua ib lub teeb-emitting txheej.Saum lub teeb-emitting txheej yog ib txheej ntawm hlau electrodes uas tsis muaj kev ua hauj lwm muaj nuj nqi, tsim ib tug qauv. zoo li sandwich.
high technology OLED zaub
Substrate (pob tshab yas, iav, ntawv ci) - Lub substrate yog siv los txhawb tag nrho OLED.
Anode (TRANSPARENT) - Lub anode tshem tawm electrons (nce electron "qhov") raws li tam sim no ntws los ntawm lub cuab yeej.
Qhov thauj txheej - txheej no yog tsim los ntawm cov khoom siv organic molecules uas thauj "qhov" los ntawm anode.
Luminescent txheej - Cov txheej no yog tsim los ntawm cov khoom siv organic molecules (raws li qhov tsis zoo ntawm cov txheej txheem conductive) qhov twg cov txheej txheem luminescence tshwm sim.
Electron thauj txheej - txheej no yog tsim los ntawm cov khoom siv organic molecules uas thauj electrons los ntawm cathode.
Cathodes (uas tuaj yeem ua pob tshab lossis opaque, nyob ntawm hom OLED) - Thaum cov khoom siv tam sim no ntws los, cov cathodes txhaj cov electrons rau hauv Circuit Court.
Cov txheej txheem luminescence ntawm OLED feem ntau muaj tsib theem hauv qab no:
① Kev txhaj tshuaj tiv thaiv kab mob: nyob rau hauv qhov kev txiav txim ntawm ib qho hluav taws xob sab nraud, hluav taws xob thiab qhov yog txhaj rau hauv cov organic ua haujlwm txheej sandwiched ntawm electrodes los ntawm cathode thiab anode, feem.
② Carrier thauj: cov khoom siv hluav taws xob thiab lub qhov txav mus los ntawm cov txheej txheem thauj hluav taws xob thiab qhov chaw thauj mus rau txheej txheej luminescent, feem.
③ Carrier recombination: tom qab cov electrons thiab qhov raug txhaj rau hauv cov luminescent txheej, lawv tau khi ua ke los tsim electron lub qhov khub, uas yog, excitons, vim yog kev ua ntawm Coulomb quab yuam.
④ Exciton tsiv teb tsaws: Vim qhov tsis sib xws ntawm cov khoom siv hluav taws xob thiab lub qhov thauj, lub ntsiab exciton tsim cheeb tsam feem ntau tsis npog tag nrho cov luminescence txheej, yog li diffusion migration yuav tshwm sim vim qhov concentration gradient.
⑤ Exciton hluav taws xob degenerates photons: Ib qho kev hloov pauv ntawm exciton radiative uas emits photons thiab tso tawm lub zog.
