Kwitekhnoloji yanamhlanje yokubonisa isiphelo esiphezulu, i-OLED (i-Organic Light-Emitting Diode) kunye ne-QLED (i-Quantum Dot Light-Emitting Diode) ngokungathandabuzekiyo ziingongoma ezimbini eziphambili ekugxilwe kuzo. Nangona amagama abo afanayo, ahluke kakhulu kwimigaqo yobugcisa, ukusebenza, kunye neenkqubo zokuvelisa, phantse ukumela iindlela ezimbini ezihluke ngokupheleleyo zokuphuhlisa iteknoloji yokubonisa.
Ngokusisiseko, itekhnoloji yokubonisa i-OLED isekwe kumgaqo we-organic electroluminescence, ngelixa i-QLED ixhomekeke kwindlela ye-electroluminescent okanye ye-photoluminescent ye-inorganic quantum dots. Kuba imathiriyeli ye-inorganic ngokubanzi inozinzo oluphezulu lwe-thermal kunye neekhemikhali, i-QLED ngokwethiyori ineengenelo malunga nokuzinza komthombo wokukhanya kunye nobomi. Yiyo loo nto abaninzi bejonga i-QLED njengesikhokelo esithembisayo setekhnoloji yokubonisa isizukulwana esilandelayo.
Ukubeka ngokulula, i-OLED ikhupha ukukhanya ngokusebenzisa izinto eziphilayo, ngelixa i-QLED ikhupha ukukhanya ngamachaphaza e-inorganic quantum. Ukuba i-LED (i-Light-Emitting Diode) ithelekiswa "nomama," ngoko i-Q kunye ne-O ibonisa iindlela ezimbini ezahlukeneyo zobuchwepheshe "zoyise". I-LED ngokwayo, njengesixhobo sokukhanyisa ukukhanya kwe-semiconductor, ivuselela amandla okukhanya xa ikhoyo ngoku idlula kwizinto ze-luminescent, ifezekisa ukuguqulwa kwe-photoelectric.
Nangona zombini i-OLED kunye ne-QLED zisekwe kumgaqo osisiseko wokukhutshwa kokukhanya kwe-LED, ziyodlula kude imiboniso ye-LED yesiko ngokwendlela yokusebenza kakuhle, ubuninzi bepixel, ukusebenza kombala, kunye nolawulo lokusetyenziswa kwamandla. Iziboniso ze-LED eziqhelekileyo zixhomekeke kwi-electroluminescent semiconductor chips, kunye nenkqubo yokuvelisa elula. Nokuba iziboniso ze-LED ezinoxinano oluphezulu zinokufikelela kuphela ubuncinci bepixel pitch ye-0.7 mm. Ngokwahlukileyo, zombini i-OLED kunye ne-QLED zifuna uphando lwezenzululwazi oluphezulu kakhulu kunye nemigangatho ye-工艺 ukusuka kwimathiriyeli ukuya kwimveliso yesixhobo. Okwangoku, ngamazwe ambalwa afana neJamani, iJapan, kunye noMzantsi Korea anamandla okuzibandakanya kumakhonkco obonelelo angasentla, okukhokelela kwizithintelo eziphezulu kakhulu zobuchwepheshe.
Inkqubo yokuvelisa ngomnye umahluko omkhulu. Iziko elikhupha ukukhanya kwe-OLED ziimolekyuli ze-organic, okwangoku ikakhulu zisebenzisa inkqubo yokuphuma komphunga-ukucubungula imathiriyeli ye-organic kwizakhiwo ezincinci ze-molekyuli phantsi kobushushu obuphezulu kwaye emva koko ziphinde zibuyiselwe kwiindawo ezichaziweyo. Le ndlela ifuna iimeko eziphakamileyo kakhulu zokusingqongileyo, ibandakanya iinkqubo ezinzima kunye nezixhobo ezichanekileyo, kwaye okona kubaluleke kakhulu, zijongene nemingeni ebalulekileyo ekuhlangabezaneni neemfuno zemveliso yezikrini ezinkulu.
Ngakolunye uhlangothi, iziko elikhupha ukukhanya kwe-QLED yi-semiconductor nanocrystals, enokuthi inyibilike kwizisombululo ezahlukeneyo. Oku kuvumela ukulungiselela ngeendlela ezisekelwe kwisisombululo, ezifana neteknoloji yoshicilelo. Ngakolunye uhlangothi, oku kunokunciphisa ngokufanelekileyo iindleko zokuvelisa, kwaye kwelinye icala, iphula imida yobukhulu besikrini, ukwandisa iimeko zesicelo.
Isishwankathelo, i-OLED kunye ne-QLED zimele incopho yetekhnoloji ye-organic kunye ne-inorganic light-emitting, nganye inamandla kunye nobuthathaka bayo. I-OLED yaziwa ngomlinganiselo wayo ophezulu kakhulu wokuchasana kunye neempawu zokubonisa eziguquguqukayo, ngelixa i-QLED ithandwa ngokuzinza kwayo kunye neendleko ezinokubakho. Abathengi kufuneka benze ukhetho olusekelwe kwiimfuno zabo zokusetyenziswa.
