Ubuchwepheshe be-LED sebuphenduke inketho yokukhanyisa ezinhlelweni ezahlukahlukene. Kusukela ezindlini zokuhlala kuya ezakhiweni zezentengiselwano, izibani ze-LED seziyinto eyisisekelo ngenxa yokusebenza kahle kwazo kwamandla, ubude besikhathi sokuphila, nokuguquguquka. Kodwa-ke, ngokuthuthuka okusheshayo kwezobuchwepheshe, abanye basala bezibuza ukuthi ingabe ikhona yini enye indlela engcono kunezibani ze-LED.
I-LED, emele i-light-emitting diode, iyisisetshenziswa se-semiconductor esikhipha ukukhanya lapho umsinga kagesi udlula kuyo. Lobu buchwepheshe buye benza izinguquko embonini yokukhanyisa ngokunikeza izinzuzo eziningi ngaphezu kokukhanyisa kwendabuko kwe-incandescent ngisho nezibani ze-fluorescent. Izibani ze-LED ziwonga kakhulu amandla, zikhiqiza ukukhanya okwengeziwe kuyilapho zisebenzisa amandla amancane. Futhi zinesikhathi eside sokuphila, kunciphisa imvamisa yokushintshwa nokugcinwa. Ukwengeza, izibani ze-LED zingenziwa ngezindlela ezihlukahlukene nobukhulu obuhlukahlukene, okubenza bafaneleke izinhlelo zokusebenza ezahlukene.
Naphezu kwezinzuzo eziningi zobuchwepheshe be-LED, abacwaningi nososayensi bahlale belwela ukuthuthukisa izixazululo zokukhanyisa ezithuthuke kakhulu. Obunye ubuchwepheshe obunakwa yi-OLED, noma i-organic light-emitting diode. Ngokungafani namalambu e-LED endabuko, asebenzisa izinto ezingaphili, ama-OLED asebenzisa izinhlanganisela eziphilayo ezikhipha ukukhanya lapho kusetshenziswa umsinga kagesi. Lokhu kubangela umthombo wokukhanya ozacile, oguquguqukayo, futhi okwazi ngisho nokuba sobala.
Ubuchwepheshe be-OLED yikhono layo lokukhiqiza ukunemba okungcono kombala nokugqama. Ama-OLED ayakwazi ukukhiqiza abamnyama bangempela nemibala egqamile, okuwenza alungele izinhlelo zokusebenza ezifana nomabonakude nezibonisi. Ukwengeza, amalambu e-OLED aziwa ngokugqama kwawo okufanayo kuyo yonke indawo, asusa isidingo sama-diffuser eyengeziwe noma izibonisi.
Ubuchwepheshe obusafufusa obubhekwa njengento engase ibe enye esikhundleni se-LED i-micro-LED. Ama-Micro-LED mancane nakakhulu kunama-LED endabuko, ngokuvamile anesilinganiso esingaphansi kwama-micrometer angu-100. Lawa ma-LED amancane angasetshenziswa ukudala izibonisi ezinokulungiswa okuphezulu nezixazululo zokukhanyisa ngokusebenza kahle kwamandla nokukhanya. Nakuba ubuchwepheshe be-micro-LED busezigabeni zokuqala zokuthuthuka, bunamandla okwenza kangcono kunama-LED avamile ngokwekhwalithi yesithombe nokusebenza kukonke.
Nakuba ubuchwepheshe be-OLED kanye ne-micro-LED bubonisa isithembiso njengendlela engase ibe khona esikhundleni sezibani ze-LED, kubalulekile ukucabangela isimo samanje sobuchwepheshe be-LED. Izibani ze-LED sezivele zizisungule njengesixazululo sokukhanyisa esinokwethenjelwa nesingabizi kakhulu sezinhlelo zokusebenza ezihlukahlukene. Ubuchwepheshe buyaqhubeka nokuthuthuka, ngokuthuthuka ekusebenzeni kahle, ukugqama, nokunikezwa kombala. Ukwengeza, ukwamukelwa okusabalele kwezibani ze-LED kuye kwaholela ezomnotho wesilinganiso, okuwenza athengeke kakhudlwana kubathengi nakumabhizinisi.
Kuyacaca ukuthi ubuchwepheshe be-LED bubeke izinga eliphezulu lokukhanyisa okuzonga amandla futhi okuhlala isikhathi eside. Kodwa-ke, njengoba intuthuko kubuchwepheshe be-OLED kanye ne-micro-LED iqhubeka nokuthuthuka, kungase kufike isikhathi lapho lezi zindlela ezihlukile zidlula amandla ezibani ze-LED zendabuko. Okwamanje, kubalulekile ukugcina iso ekuthuthukisweni kobuchwepheshe bokukhanyisa futhi ucabangele izidingo ezithile zesicelo ngasinye lapho ukhetha isisombululo sokukhanyisa esingcono kakhulu.
kuyilapho ubuchwepheshe be-LED buye bushintsha umdlalo embonini yokukhanyisa, kukhona ubuchwepheshe obuvelayo obufana ne-OLED ne-micro-LED ebonisa amandla njengezinye izindlela. Kubalulekile ukuqhubeka nokucwaninga nokuthuthukisa lobu buchwepheshe ukuze kuthuthukiswe ukusebenza kahle nokusebenza kwezixazululo zokukhanyisa. Njengoba isidingo sokukhanyisa amandla ngendlela eyongayo nekhwalithi ephezulu sikhula, kungenzeka ukuthi kungase kube nobuchwepheshe obungcono kune-LED esikhathini esizayo esiseduze.
