Kwiiteknoloji zokubonisa eziphambili zanamhlanje, i-OLED (i-Organic Light-Emitting Diode) kunye ne-QLED (i-Quantum Dot Light-Emitting Diode) ngokungathandabuzekiyo ziindawo ezimbini eziphambili ezijongwayo. Nangona amagama azo efana, zahluke kakhulu kwimigaqo yobugcisa, ukusebenza, kunye neenkqubo zokuvelisa, phantse zimele iindlela ezimbini ezahlukeneyo zophuhliso lwetekhnoloji yokubonisa.
Ngokusisiseko, iteknoloji yokubonisa i-OLED isekelwe kumgaqo we-organic electroluminescence, ngelixa i-QLED ixhomekeke kwindlela ye-electroluminescent okanye i-photoluminescent yamachaphaza e-inorganic quantum. Ekubeni izinto ezingaphiliyo zihlala zinozinzo oluphezulu lobushushu kunye neekhemikhali, i-QLED ngokwethiyori ineenzuzo ngokubhekiselele kuzinzo lomthombo wokukhanya kunye nobomi bayo. Yingakho abaninzi becinga ukuba i-QLED yindlela ethembisayo yobuchwepheshe bokubonisa besizukulwana esilandelayo.
Ngamafutshane, i-OLED ikhupha ukukhanya ngezinto 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 zimele iindlela ezimbini ezahlukeneyo zobuchwepheshe "bukayise". I-LED ngokwayo, njengesixhobo sokukhupha ukukhanya se-semiconductor, ivuselela amandla okukhanya xa umbane udlula kwizinto ezikhanyayo, nto leyo efikelela ekuguqulweni kwe-photoelectric.
Nangona zombini i-OLED kunye ne-QLED zisekelwe kumgaqo osisiseko wokukhupha ukukhanya we-LED, zidlula kakhulu iziboniso ze-LED zemveli ngokubhekiselele ekusebenzeni kakuhle kokukhanya, uxinano lwee-pixel, ukusebenza kombala, kunye nolawulo lokusetyenziswa kwamandla. Iziboniso ze-LED eziqhelekileyo zixhomekeke kwiitships ze-electroluminescent semiconductor, ngenkqubo yokuvelisa elula. Neziboniso ze-LED ezinoxinano oluphezulu ngoku zinokufikelela kuphela ubuncinci be-pixel pitch ye-0.7 mm. Ngokwahlukileyo koko, zombini i-OLED kunye ne-QLED zifuna uphando lwesayensi oluphezulu kakhulu kunye nemigangatho ukusuka kwizixhobo ukuya kwimveliso yezixhobo. Okwangoku, amazwe ambalwa kuphela afana neJamani, iJapan, kunye neSouth Korea anakho ukubandakanyeka kwiindlela zawo zokubonelela eziphezulu, nto leyo ebangela imiqobo ephezulu kakhulu yetekhnoloji.
Inkqubo yokuvelisa yenye umahluko omkhulu. Iziko elikhupha ukukhanya le-OLED ziimolekyuli zendalo, okwangoku ezisebenzisa kakhulu inkqubo yokufuma—ukucubungula izinto zendalo zibe zizakhiwo ezincinci zemolekyuli phantsi kobushushu obuphezulu zize ziphinde zibekwe kwakhona kwiindawo ezithile. Le ndlela ifuna iimeko eziphezulu kakhulu zendalo, ibandakanya iinkqubo ezintsonkothileyo kunye nezixhobo ezichanekileyo, kwaye okona kubaluleke kakhulu, ijongene nemingeni ebalulekileyo ekuhlangabezaneni neemfuno zemveliso yezikrini ezinkulu.
Kwelinye icala, iziko elikhupha ukukhanya le-QLED zii-nanocrystals ze-semiconductor, ezinokunyibilikiswa kwizisombululo ezahlukeneyo. Oku kuvumela ukulungiswa ngeendlela ezisekelwe kwisisombululo, ezifana netekhnoloji yokuprinta. Kwelinye icala, oku kunokunciphisa ngempumelelo iindleko zokuvelisa, kwaye kwelinye icala, kudlula kwimida yobukhulu besikrini, kwandise iimeko zesicelo.
Ngamafutshane, i-OLED kunye ne-QLED zimele incopho yetekhnoloji yokukhupha ukukhanya kwezinto eziphilayo nezingaphiliyo, nganye inamandla kunye nobuthathaka bayo. I-OLED yaziwa ngomlinganiselo wayo ophezulu kakhulu wokungafani kunye neempawu zokubonisa eziguquguqukayo, ngelixa i-QLED ithandwa ngenxa yozinzo lwayo lwezinto kunye nokukwazi kwayo ukubiza. Abathengi kufuneka benze ukhetho ngokusekelwe kwiimfuno zabo zokwenyani zokusetyenziswa.
