I-OLED inokukhanya kwayo okuphezulu okukhipha ukukhanya, i-engeli yokubuka ebanzi, impendulo esheshayo, ukusetshenziswa kwamandla aphansi, futhi ingenziwa amadivayisi okubonisa aguquguqukayo, kubhekwa njengokufaka esikhundleni sobuchwepheshe bekristalu eliwuketshezi olufanele isizukulwane esilandelayo sobuchwepheshe bokubonisa. Ingxenye eyinhloko yesibonisi se-OLED yi-sub-pixel ngayinye enekhono lokukhanyisa isici esikhipha ukukhanya se-OLED. Isakhiwo esiyisisekelo sesici esikhipha ukukhanya se-OLED sihlanganisa i-anode, i-cathode, kanye ne-sandwiched phakathi kwesendlalelo esisebenzayo esikhipha ukukhanya, lapho isendlalelo esikhipha ukukhanya Ngokusho komsebenzi wezinto ze-OLED kudivayisi kanye nesakhiwo sedivayisi, singahlukaniswa njengesendlalelo sokufaka imbobo (HIL), isendlalelo sokuhambisa imbobo (HTL), isendlalelo sokukhipha ukukhanya (EML) isendlalelo sokuhambisa i-electron (ETL), isendlalelo sokufaka i-electron (EIL) nezinye izinto.
Kuma-OLED, ungqimba lokujova imbobo kanye nongqimba lokuthuthwa kwembobo kusetshenziselwa ukuthuthukisa ukusebenza kahle kokujova kwembobo, kuyilapho ungqimba lokujova i-electron kanye nongqimba lokuthuthwa kwe-electron kusetshenziselwa ukuthuthukisa ukusebenza kahle kokujova kwama-electron. Ezinye zezinto ezikhipha ukukhanya ngokwazo zinomsebenzi wokuthuthwa kwembobo noma ukuthuthwa kwe-electron, ngokuvamile okubizwa ngokuthi i-main luminescent; ungqimba lwezinto ezikhipha ukukhanya enanini elincane lamadayi e-fluorescent noma e-phosphorescent afakwe i-doped organic angawathola emzimbeni okhanyayo oyinhloko wokudluliswa kwamandla, futhi ngokubamba nokukhipha umbala ohlukile wokukhanya, izinto ezikhipha ukukhanya ezifakwe i-doped zivame ukubizwa nangokuthi umzimba okhipha ukukhanya wezivakashi noma umzimba okhipha ukukhanya ofakwe i-doped.
2. Izimiso Eziyisisekelo Zokukhishwa Kokukhanya Kwedivayisi ye-OLED
Kusetshenziswa i-voltage kudivayisi ye-OLED, bese kuthi imigodi nama-electron afakwe kungqimba lwe-OLED kusukela ku-anode kanye ne-cathode yedivayisi, ngokulandelana. Imigodi nama-electron ezintweni ezikhipha ukukhanya eziphilayo ahlanganiswe futhi akhulule amandla, kanye nokudluliselwa kwamandla okuqhubekayo kudlulisa ama-molecule ezinto ezikhipha ukukhanya eziphilayo, ukuze ajabulele isimo esijabulisayo, bese kuthi i-exciton evela esimweni esijabulisayo ibuyele esimweni somhlaba, amandla ngesimo sokukhululwa, futhi ekugcineni aqaphele ukukhanya kwe-electroluminescence yedivayisi ye-OLED.
Ngokuvamile, ifilimu ku-OLED ifaka ifilimu ye-electrode eqhubayo kanye nesendlalelo ngasinye sezinto ezikhipha ukukhanya eziphilayo. Njengamanje, ama-anode amadivayisi e-OLED afinyelele ekukhiqizweni okukhulu avame ukulungiswa kusetshenziswa ubuchwepheshe bokunciphisa ukulawula kwamagnetic. Ama-cathode kanye nezendlalelo ze-luminescent eziphilayo ngokuvamile zilungiswa ngokuhwamuka kwe-vacuum.
