Kubuchwepheshe bokubonisa obusezingeni eliphezulu banamuhla, i-OLED (i-Organic Light-Emitting Diode) kanye ne-QLED (i-Quantum Dot Light-Emitting Diode) ngokungangabazeki ziyizindawo ezimbili ezibalulekile ezigxile kuzo. Nakuba amagama azo efana, ahluke kakhulu ezimisweni zobuchwepheshe, ukusebenza, kanye nezinqubo zokukhiqiza, cishe amelela izindlela ezimbili ezihlukene ngokuphelele zokuthuthukiswa kobuchwepheshe bokubonisa.
Ngokuyisisekelo, ubuchwepheshe bokubonisa be-OLED busekelwe esimisweni se-electroluminescence yezinto eziphilayo, kuyilapho i-QLED incike endleleni ye-electroluminescent noma ye-photoluminescent yamachashazi e-inorganic quantum. Njengoba izinto ezingaphili ngokuvamile zinokuzinza okuphezulu kokushisa namakhemikhali, i-QLED ngokwemfundiso inezinzuzo maqondana nokuzinza komthombo wokukhanya kanye nokuphila isikhathi eside. Yingakho futhi abaningi bebheka i-QLED njengesiqondiso esithembisayo sobuchwepheshe bokubonisa besizukulwane esilandelayo.
Kalula nje, i-OLED ikhipha ukukhanya ngezinto eziphilayo, kuyilapho i-QLED ikhipha ukukhanya ngamachashazi e-quantum angaphili. Uma i-LED (i-Light-Emitting Diode) iqhathaniswa “nomama,” khona-ke i-Q ne-O zimelela izindlela ezimbili zobuchwepheshe “zobaba” ezihlukene. I-LED ngokwayo, njengedivayisi ye-semiconductor ekhipha ukukhanya, ivusa amandla okukhanya lapho ugesi udlula ezintweni ezikhanyayo, ifinyelele ukuguqulwa kwe-photoelectric.
Nakuba kokubili i-OLED ne-QLED zisekelwe esimisweni esiyisisekelo sokukhipha ukukhanya kwe-LED, zidlula kakhulu izibonisi ze-LED zendabuko ngokusebenza kahle okukhanyayo, ukuminyana kwamaphikseli, ukusebenza kombala, kanye nokulawula ukusetshenziswa kwamandla. Izibonisi ze-LED ezijwayelekile zithembele kuma-electroluminescent semiconductor chips, ngenqubo yokukhiqiza elula. Ngisho nezibonisi ze-LED ezincane eziminyene kakhulu okwamanje zingafinyelela kuphela iphimbo elincane lamaphikseli elingu-0.7 mm. Ngokuphambene nalokho, zombili i-OLED ne-QLED zidinga ucwaningo lwesayensi oluphezulu kakhulu kanye nezindinganiso kusukela ezintweni kuya ekukhiqizweni kwamadivayisi. Njengamanje, amazwe ambalwa kuphela njengeJalimane, iJapan, neNingizimu Korea anamandla okuzibandakanya emikhakheni yawo yokuphakelwa ephezulu, okuholela ezithiyo zobuchwepheshe eziphezulu kakhulu.
Inqubo yokukhiqiza ingenye umehluko omkhulu. Isikhungo esikhipha ukukhanya se-OLED ama-molecule e-organic, okwamanje asebenzisa kakhulu inqubo yokuhwamuka—ukucubungula izinto eziphilayo zibe izakhiwo ezincane zama-molecule ngaphansi kwamazinga okushisa aphezulu bese ezifaka kabusha ngokunembile ezindaweni ezithile. Le ndlela idinga izimo zemvelo eziphakeme kakhulu, ihilela izinqubo eziyinkimbinkimbi kanye nemishini eqondile, futhi okubaluleke kakhulu, ibhekene nezinselele ezinkulu ekuhlangabezaneni nezidingo zokukhiqiza zezikrini ezinkulu.
Ngakolunye uhlangothi, isikhungo esikhipha ukukhanya se-QLED yi-semiconductor nanocrystals, engancibilikiswa ezixazululweni ezahlukahlukene. Lokhu kuvumela ukulungiselela ngezindlela ezisekelwe kwisisombululo, njengobuchwepheshe bokuphrinta. Ngakolunye uhlangothi, lokhu kunganciphisa ngempumelelo izindleko zokukhiqiza, kanti ngakolunye uhlangothi, kudlula imikhawulo yosayizi wesikrini, kwandise izimo zohlelo lokusebenza.
Ngamafuphi, i-OLED ne-QLED zimelela ubuchwepheshe obukhipha ukukhanya kwezinto eziphilayo nezingaphili, ngayinye inamandla nobuthakathaka bayo. I-OLED yaziwa ngesilinganiso sayo sokungafani okuphezulu kakhulu kanye nezici zokubonisa eziguquguqukayo, kuyilapho i-QLED ithandwa ngenxa yokuzinza kwayo kwezinto kanye namathuba ezindleko. Abathengi kufanele benze izinqumo ngokusekelwe ezidingweni zabo zangempela zokusebenzisa.
