I-OLED inokukhanya kwayo okuphezulu okukhipha ukukhanya, i-engeli yokubuka ebanzi, impendulo esheshayo, ukusetshenziswa kwamandla aphansi, futhi ingenziwa amadivaysi okubonisa aguquguqukayo, ibhekwa njengokungena esikhundleni sobuchwepheshe bekristalu obuwuketshezi obulungele isizukulwane esilandelayo sobuchwepheshe bokuboniswa. ingxenye eyinhloko yesibonisi se-OLED iyiphikiseli encane ngayinye enekhono lokukhipha isici esikhipha ukukhanya kwe-OLED. isakhiwo esiyisisekelo sesici esikhipha ukukhanya kwe-OLED sihlanganisa i-anode, i-cathode, futhi ihlanganiswe phakathi kongqimba olusebenzayo olukhipha ukukhanya, ungqimba olukhipha ukukhanya Ngokusho komsebenzi wezinto ze-OLED kudivayisi kanye nesakhiwo sedivayisi, singahlukaniswa njengesendlalelo somjovo wembobo (HIL), ungqimba wokuthutha imbobo (HTL), ungqimba okhipha ukukhanya (EMM) ungqimba lwe-electron nezinye izinto zokuthutha ze-electron (EMLE) nezinye izinto zokuthutha ze-electron.
Kuma-OLED, ungqimba lomjovo wembobo kanye nesendlalelo sokuthutha imbobo kusetshenziswa ukuthuthukisa ukusebenza kahle komjovo wezimbobo, kuyilapho ungqimba lomjovo we-electron kanye nesendlalelo sokuthutha i-electron kusetshenziswa ukuthuthukisa ukusebenza kahle komjovo wama-electron. Ezinye zezinto ezikhipha ukukhanya ngokwazo zinomsebenzi wokuthutha imbobo noma ukuthutha nge-electron, ngokuvamile okubizwa ngokuthi i-luminescent eyinhloko; ungqimba lwento ekhipha ukukhanya enanini elincane lodayi be-organic fluorescent noma be-phosphorescent bangathola kusukela kumzimba okhanyayo oyinhloko wokudluliswa kwamandla, futhi ngokuthwebula inkampani yenethiwekhi futhi ikhiphe umbala ohlukile wokukhanya, into ekhipha ukukhanya ene-doped ngokuvamile ibizwa nangokuthi i-luminescent yesivakashi noma umzimba okhipha ukukhanya one-doped.
2. Izimiso Eziyisisekelo Zokukhishwa Kokukhanya Kwedivayisi ye-OLED
I-voltage isetshenziswa kudivayisi ye-OLED, futhi izimbobo nama-electron kufakwa ungqimba lwe-OLED kusuka ku-anode ne-cathode yedivayisi, ngokulandelana. Izimbobo nama-electron ku-organic light-emitting material composite kanye nokukhulula amandla, kanye nokudluliswa kwamandla okuqhubekayo kwama-molecule ezinto ezibonakalayo akhipha ukukhanya, ukuze bajabulele isimo senjabulo, bese i-exciton evela esimweni esijabulisayo ibuyele esimweni esiphansi, amandla ngendlela yokukhululwa, futhi ekugcineni ibone i-electroluminescence yedivayisi ye-OLED.
Ngokuvamile, ifilimu eku-OLED ihlanganisa ifilimu ye-electrode eqhubayo kanye nongqimba ngalunye lwento ephilayo ekhipha ukukhanya okukhanyayo. Njengamanje, ama-anode amadivaysi e-OLED azuze ukukhiqizwa ngobuningi avame ukulungiswa kusetshenziswa ubuchwepheshe bokunciphisa amandla kazibuthe. Ama-Cathodes kanye nezingqimba ze-organic luminescent ngokuvamile zilungiswa ngokuhwamuka kwe-vacuum.
