Emkhakheni wamanje wobuchwepheshe bokuboniswa, izikrini ze-OLED zigqama ngokusebenza kwazo kombala okugqamile nokudonsa amehlo, zithola ukuthandwa kabanzi ngabakhi bombukiso nabathengi. Ngakho-ke, kungani izibonisi ze-OLED zingaletha imibala egqamile kangaka? Lokhu akuhlukaniseki ezimisweni zabo zobuchwepheshe eziyingqayizivele kanye nezinzuzo ezibalulekile.
I-OLED, noma i-organic light-emitting diode, iwubuchwepheshe bokubonisa lapho izinto ze-organic semiconductor nezinto ezikhipha ukukhanya zikhipha ukukhanya ngokuzenzakalelayo ngaphansi kwedrayivu yamanje. Ngokungafani nezibonisi zekristalu eziwuketshezi ezivamile (ama-LCD), i-OLED ayidingi ukukhanya kwangemuva, njengoba iphikseli ngalinye lingakhipha ukukhanya ngokuzimela. Lesi sici sokuzikhulula singenye yezinto ezibalulekile ezibangela imibala egqamile ye-OLED. Kuma-LCDs, ukukhanya okukhishwa i-backlight kudinga ukudlula kungqimba lwekristalu ewuketshezi nezihlungi zombala ukuze kwethule imibala, inqubo eholela ekulahlekeni kokukhanya okuncane, okuthinta ukuhlanzeka kombala nokudlidliza.
Ngokuphambene, amaphikseli e-OLED akhipha ukukhanya ngokuqondile, agweme ngempumelelo ukulahlekelwa ukukhanya futhi enze ukusebenza kombala kuhlanzeke futhi kugqame. Ngokombono wezobuchwepheshe, ubuchwepheshe obuthile be-OLED, obufana ne-WRGB OLED, bamukela isakhiwo se-subpixel esinemibala emine, okusho ukuthi ipikseli ngayinye inamaphikseli amancane amane: W (amhlophe), R (obomvu), G (oluhlaza), kanye no-B (oluhlaza okwesibhakabhaka). Uma kuqhathaniswa namaphikseli endabuko anemibala emithathu, lobu buchwepheshe bemibala emine bungashayela amaphikseli amancane engeziwe. Uma sithatha i-HD egcwele njengesibonelo, izibonisi ezijwayelekile zingase zibe namaphikseli angaphansi ayizigidi ezingu-6.2 kuphela, kuyilapho i-WRGB OLED inamaphikseli amancane afika ezigidini ezingu-8.3 ukuze kuboniswe umbala, okwenza imibala inothe futhi inemininingwane eyengeziwe.
Ngesikhathi esifanayo, i-WRGB OLED isebenzisa ubuchwepheshe bokuthuthukisa umbala, igwema ngempumelelo isenzakalo sokushintsha umbala esingase senzeke kuma-OLED avamile e-RGB anemibala emithathu lapho kuboniswa okuluhlaza okwesibhakabhaka, ngaleyo ndlela yethule u-100% wemibala enencazelo ephezulu eseduze namathoni emvelo futhi ithuthukisa ngokuphawulekayo ukunyakaziswa kombala nokunemba. Kubakhiqizi bokubonisa, izinzuzo zobuchwepheshe be-OLED zibanika isikhundla esivumayo emqhudelwaneni wemakethe.
Abakhiqizi abaningi ngokwengeziwe batshala imali ocwaningweni, ekuthuthukisweni, nasekukhiqizweni kwezibonisi ze-OLED, bethuthukisa izinqubo ngokuqhubekayo futhi bathuthukise ikhwalithi yomkhiqizo. Isibonelo, ulayini wokuqala wokukhiqiza emhlabeni usebenzisa ubuchwepheshe be-OLED obuphrintiwe usuqalile ukwakhiwa efektri e-Wuhan. Ubuchwepheshe obuphrintiwe be-OLED bunikeza inzuzo ye-gamut yombala obanzi, ithuthukisa ngokwengeziwe ukusebenza kombala kwezibonisi ze-OLED. Ngaphezu kwalokho, lobu buchwepheshe, obufana nokuphrinta kwe-inkjet, buvumela ukuphrinta okunembile kwezinto ezikhipha ukukhanya, hhayi nje ukuphinda kabili ukusebenza kahle kokusetshenziswa kwezinto ezibonakalayo kodwa futhi kunika amandla ukukhiqiza ngaphansi kwezidingo eziphansi zemvelo, kunciphisa ngempumelelo ukusetshenziswa kwamandla embonini. Lokhu kubaluleke kakhulu kubakhiqizi ukuze banciphise izindleko futhi bathuthukise ukusebenza kahle kokukhiqiza.
Emkhakheni wezibonisi ngokwezifiso, imibala egqamile ye-OLED iphinda ibonise ukukhanga okuyingqayizivele. Ngenxa yokusebenza kwazo kombala ocebile nokucacile, izibonisi ze-OLED zingahlangabezana nezidingo zombala ezidingeka kakhulu ngezidingo zangokwezifiso, njengemikhiqizo ye-elekthronikhi esezingeni eliphezulu nezinto zokusebenza zokubonisa ezichwepheshile. Ukugqama kwawo okuphezulu nezici ze-gamut yombala obanzi zinika amandla ukwethulwa okucacile kwemininingwane yesithombe nevidiyo, enezendlalelo zemibala ehluke kakhulu, enikeza abasebenzisi umuzwa wokubuka ogxilile.
Kafushane, izibonisi ze-OLED, nomgomo wazo wokuzidela, izici zobuchwepheshe ezithuthukisiwe, kanye nempumelelo eqhubekayo ezinqubweni zokukhiqiza, sekufana nemibala egqamile. Kungakhathaliseki ukuthi okokukhiqiza ngezinga elikhulu ngabakhiqizi besibonisi noma izidingo eziqondene nawe zezibonisi ngokwezifiso, i-OLED ibonisa ukusebenza okukhethekile namandla amakhulu, eqhubeka iholela ekuthuthukisweni kobuchwepheshe bokubonisa ikusasa eliqhakazile nelinemibalabala.
