Kubuchwepheshe banamuhla bokubonisa obusezingeni eliphezulu, i-OLED (i-Organic Light-Emitting Diode) ne-QLED (Quantum Dot Light-Emitting Diode) ngokungangabazeki yizindawo ezimbili ezibalulekile okugxilwe kuzo. Nakuba amagama abo afana, ahluke kakhulu ezimisweni zobuchwepheshe, ukusebenza, nezinqubo zokukhiqiza, cishe amele izindlela ezimbili ezihluke ngokuphelele zokuthuthukiswa kobuchwepheshe bokuboniswa.
Ngokuyisisekelo, ubuchwepheshe bokubonisa i-OLED busekelwe kumgomo we-organic electroluminescence, kuyilapho i-QLED incike kumshini we-electroluminescent noma we-photoluminescent wamachashazi we-inorganic quantum. Njengoba izinto ezingaphili ngokuvamile zinokuzinza okuphezulu kwe-thermal namakhemikhali, i-QLED ngokwethiyori inezinzuzo mayelana nokuzinza komthombo wokukhanya nempilo yokuphila. Yingakho futhi abaningi bebheka i-QLED njengesiqondisindlela esithembisayo sobuchwepheshe bokubonisa besizukulwane esilandelayo.
Kalula nje, i-OLED ikhipha ukukhanya ngezinto eziphilayo, kuyilapho i-QLED ikhipha ukukhanya ngamachashazi we-quantum we-inorganic. Uma i-LED (i-Light-Emitting Diode) iqhathaniswa “nomama,” khona-ke i-Q ne-O imelela izindlela zobuchwepheshe “zobaba” ezimbili ezihlukene. I-LED ngokwayo, njengedivayisi ekhipha ukukhanya kwe-semiconductor, ijabulisa amandla okukhanya lapho okwamanje idlula ezintweni ze-luminescent, ifinyelela ukuguqulwa kwe-photoelectric.
Nakuba kokubili i-OLED ne-QLED zisekelwe kumgomo oyinhloko wokukhipha ukukhanya kwe-LED, zidlula kude izibonisi ze-LED ezivamile ngokuya ngokusebenza kahle okukhanyayo, ukuminyana kwe-pixel, ukusebenza kombala, nokulawula ukusetshenziswa kwamandla. Izibonisi ze-LED ezijwayelekile zincike kuma-electroluminescent semiconductor chips, anenqubo yokukhiqiza elula. Ngisho nezibonisi ze-LED ezinephimbo elincane elinobukhulu obuphakeme okwamanje zingafinyelela ubuncane bephikseli bokuphakama obungu-0.7 mm. Ngokuphambene, kokubili i-OLED ne-QLED zidinga ucwaningo lwesayensi oluphakeme kakhulu kanye namazinga we-工艺 kusuka ezintweni zokwakha kuye ekukhiqizeni idivayisi. Njengamanje, amazwe ambalwa kuphela afana neJalimane, i-Japan, ne-South Korea anamandla okuzibandakanya kumaketanga awo okunikezela ngomfula, okuholela emigomeni ephezulu kakhulu yezobuchwepheshe.
Inqubo yokukhiqiza ingomunye umehluko omkhulu. Isikhungo esikhipha ukukhanya kwe-OLED amangqamuzana ezinto eziphilayo, okwamanje ikakhulukazi asebenzisa inqubo yokuhwamuka—ukucubungula izinto eziphilayo zibe izakhiwo zamangqamuzana amancane ngaphansi kwamazinga okushisa aphakeme abese ewabeka kabusha ngokunembile ezindaweni ezithile. Le ndlela idinga izimo zemvelo eziphakeme kakhulu, ihlanganisa izinqubo eziyinkimbinkimbi kanye nemishini enembile, futhi okubaluleke kakhulu, ibhekana nezinselele ezibalulekile ekuhlangabezaneni nezidingo zokukhiqiza zezikrini ezinosayizi omkhulu.
Ngakolunye uhlangothi, isikhungo esikhipha ukukhanya kwe-QLED yi-semiconductor nanocrystals, engancibilika ezixazululweni ezihlukahlukene. Lokhu kuvumela ukulungiselela ngezindlela ezisekelwe kwisixazululo, njengobuchwepheshe bokuphrinta. Ngakolunye uhlangothi, lokhu kunganciphisa ngempumelelo izindleko zokukhiqiza, futhi ngakolunye uhlangothi, kweqa imikhawulo yosayizi wesikrini, ukwandisa izimo zohlelo lokusebenza.
Kafushane, i-OLED ne-QLED zimelela isiqongo sobuchwepheshe bokukhipha ukukhanya kwe-organic kanye ne-inorganic, ngayinye inamandla nobuthakathaka bayo. I-OLED yaziwa ngesilinganiso sayo sokungafani esiphezulu kakhulu nezici zokubonisa eziguquguqukayo, kuyilapho i-QLED ithandwa ngokuzinza kwayo kwempahla namandla ezindleko. Abathengi kufanele benze ukukhetha ngokusekelwe ezidingweni zabo zangempela zokusebenzisa.
