OLED Waa soo gaabinta Organic Light Emitting Diode, taas oo macnaheedu yahay "Tignoolajiyada soo saarista iftiinka Organic" ee Chinese-ka ah. Fikradda ayaa ah in lakabka iftiinka-baxa uu dhex dhigo laba electrodes. iftiin.Qaabka aasaasiga ah eeOLED waa in la sameeyo lakab ka mid ah walxaha iftiimiya iftiinka organic tobanaan nanometer qaro weyn oo ku yaala indium tin oxide (ITO) muraayad ahaan sida lakabka iftiinka. sida sandwich.

Substrate (caag hufan, galaas, bireed) - Substrate-ka waxaa loo isticmaalaa in lagu taageero OLED oo dhan.
Anode (TRANSPARENT) - Anode-ku wuxuu baabi'iyaa elektaroonigga (kordhinta "daloolada" elektarooniga ah) maaddaama hadda uu dhex socdo qalabka.
Lakabka gaadiidka daloolka - Lakabkani wuxuu ka kooban yahay unugyo walxo organic ah oo ka soo qaada "godadka" anode-ka.
Lakabka iftiinka -Lakabkani wuxuu ka kooban yahay unugyo walxo organic ah (oo ka soo horjeeda lakabyada korantada) halkaasoo habka iftiinka uu ka dhaco.
Lakabka gaadiidka Electron-Lakabkani waxa uu ka kooban yahay unugyo walxo organic ah oo ka soo qaada electrons-ka cathode.
Cathodes (taas oo noqon karta mid hufan ama mugdi ah, iyadoo ku xiran nooca OLED) - Marka hadda uu dhex socdo qalabka, cathodes waxay ku durayaan elektarooniga wareegga wareegga.
Habka luminescence ee OLED wuxuu badanaa leeyahay shan marxaladood oo aasaasi ah:
① duritaanka qaade: hoos fal ee beer koronto dibadda, electrons iyo godadka waxaa lagu duraa lakabka functional organic sandwiched dhexeeya electrodes ka cathode iyo anode, siday u kala horreeyaan.
② Gaadiidka qaade: elektaroonnada la isku duray iyo godadka waxay ka guuraan lakabka gaadiidka elektaroonigga ah iyo lakabka gaadiidka daloolka ilaa lakabka iftiinka, siday u kala horreeyaan.
③ Dib-u-habaynta side: ka dib marka elektaroonnada iyo godadka lagu duro lakabka luminescent, waxay isku xidhan yihiin si ay u sameeyaan lammaane dalool elektaroonig ah, taas oo ah, exciton, sababtoo ah ficilka xoogga Coulomb.
④ Socdaalka Exciton: Sababtoo ah isku dheelitir la'aanta elektaroonigga iyo gaadiidka daloolka, gobolka samaynta exciton ee ugu weyn sida caadiga ah ma daboolo dhammaan lakabka luminescence, sidaas awgeed socdaalka faafinta ayaa dhici doona sababtoo ah feejignaanta.
Shucaaca Exciton wuxuu hoos u dhigaa sawir-qaadista: waa kala-guurka shucaaca exciton ee soo daaya sawir-qaadayaasha oo sii daaya tamar.
