I-OLED (I-Organic Light-Emitting Diode) ibhekisela kuma-organic light-emitting diode, amele umkhiqizo wenoveli endaweni yezibonisi zamaselula. Ngokungafani nobuchwepheshe be-LCD bendabuko, ubuchwepheshe bokubonisa i-OLED abudingi ukukhanya kwangemuva. Esikhundleni salokho, isebenzisa okokumbozwa kwe-organic material emincane kakhulu kanye nama-substrates engilazi (noma ama-substrates e-organic flexible). Lapho kusetshenziswa amandla kagesi, lezi zinto eziphilayo zikhipha ukukhanya. Ngaphezu kwalokho, izikrini ze-OLED zingenziwa zibe lula futhi zibe mncane, zinikeze ama-engeli wokubuka abanzi, futhi zehlise kakhulu ukusetshenziswa kwamandla. I-OLED iphinde idunyiswe njengobuchwepheshe bokubonisa besizukulwane sesithathu. Izibonisi ze-OLED azigcini nje ngokuba zizacile, zilula, futhi ziwonga amandla kakhudlwana kodwa futhi ziqhayisa ngokugqama okuphezulu, ukusebenza kahle kwe-luminescence okuphakeme, kanye nekhono lokubonisa umnyama omsulwa. Ukwengeza, zingagoba, njengoba kubonakala kuma-TV wesimanje-isikrini esigobile nama-smartphone. Namuhla, abakhiqizi abakhulu bamazwe ngamazwe bajaha ukukhuphula ukutshalwa kwezimali kwe-R&D kubuchwepheshe bokubonisa be-OLED, okuholela ekusetshenzisweni kwayo okukhulayo kuma-TV, amakhompyutha (abaqaphi), ama-smartphone, amaphilisi, neminye imikhakha. NgoJulayi 2022, i-Apple yamemezela izinhlelo zokwethula izikrini ze-OLED ohlelweni lwayo lwe-iPad eminyakeni ezayo. Amamodeli azayo we-2024 iPad azofaka amaphaneli asanda kuklanywa e-OLED, inqubo eyenza lawa maphaneli abe mancane futhi abe lula.
Umgomo wokusebenza wezibonisi ze-OLED uhluke kakhulu kulowo wama-LCD. Ngokuyinhloko iqhutshwa inkambu kagesi, ama-OLED athola ukuphuma kokukhanya ngomjovo nokuhlanganiswa kabusha kwezithwali zokushaja ku-organic semiconductor nezinto zokukhanya. Kalula nje, isikrini se-OLED sakhiwe izigidi “zamalambu” amancane.
Idivayisi ye-OLED ngokuyinhloko iqukethe i-substrate, i-anode, isendlalelo somjovo wembobo (HIL), isendlalelo sokuthutha imbobo (HTL), isendlalelo sokuvimbela i-electron (EBL), isendlalelo esikhipha umoya (EML), ungqimba ovimba imbobo (HBL), ungqimba lwe-electron transport (ETL), ungqimba lomjovo we-electron (EIL), kanye ne-cathode. Inqubo yokukhiqiza yobuchwepheshe bokuboniswa kwe-OLED idinga ubuchwepheshe obuphezulu kakhulu, ihlukaniswe kabanzi ngezinqubo zangaphambili nangemuva. Inqubo ye-front-end ngokuyinhloko ihilela i-photolithography kanye namasu okuhwamuka, kuyilapho inqubo yokubuyela emuva igxile kubuchwepheshe be-encapsulation kanye nokusika. Nakuba ubuchwepheshe be-OLED obuthuthukisiwe buphethwe kakhulu yi-Samsung ne-LG, abakhiqizi abaningi baseShayina nabo baqinisa ucwaningo lwabo ezikrinini ze-OLED, bakhulisa ukutshalwa kwezimali kuzibonisi ze-OLED. Imikhiqizo yokubonisa ye-OLED isivele ihlanganisiwe ekunikeni kwayo. Naphezu kwegebe elibalulekile uma kuqhathaniswa neziqhwaga zamazwe ngamazwe, le mikhiqizo isifinyelele izinga elisebenzisekayo.
