Ngokusho kwenkampani yezindaba yaseNingizimu Korea i-THEELEC, i-LG Display (LGD) inyusa i-R&D kubuchwepheshe bayo be-OLED besizukulwane esilandelayo obunama-stack ama-5, obenzelwe ukubhekana nezinkinga ezintathu eziyinhloko zezikrini zedeskithophu: ukukhanya okunganele, ukushiswa kwesikrini, kanye nokuphila isikhathi esifushane kwesevisi. Lobu buchwepheshe bulungele ukusetshenziswa kwi-iMac yesizukulwane esilandelayo se-Apple, ngenkathi bukwazi ukuzivumelanisa namadivayisi amaningi okugcina okuhlanganisa ama-TV nama-monitor aphezulu.

Njengamanje, amaphaneli e-OLED asezingeni eliphezulu asetshenziswa kwezentengiselwano e-LGD asebenzisa isakhiwo se-stack ezine, esiqukethe izendlalelo ezimbili eziluhlaza okwesibhakabhaka, eyodwa ebomvu kanye neyodwa eluhlaza okotshani. I-OLED esanda kuthuthukiswa enezingqimba ezi-5 ifaka ukwakheka kwezingqimba okulungiselelwe kahle okunesakhiwo esiluhlaza okwesibhakabhaka-oluhlaza okwesibhakabhaka-obomvu-oluhlaza okwesibhakabhaka (i-BGBRB), okwandisa inani lezingqimba eziluhlaza okwesibhakabhaka ezikhipha kusukela kwezimbili kuya kwezintathu. Ngaphambilini i-LGD yethule isibonisi se-OLED esingu-27-intshi esingu-5K (5120×2880) esinezingqimba ezine ze-pixel density ezingama-220 PPI, okucaciswa kwaso kuhambisana eduze nezidingo zesibonisi ze-iMac ye-Apple.

Uma kuqhathaniswa nama-smartphone namathebulethi, ama-desktop iMac avame ukusetshenziswa ukubonisa izixhumi ezimile isikhathi eside, isimo sokusetshenziswa esibeka kakhulu amaphaneli e-OLED ekugcinweni kwesithombe nasekuwohlokeni kwesikrini. Okwamanje, ukuminyana kwamaphikseli aphezulu kucindezela indawo ekhipha ukukhanya, okwenza kube nzima ukufeza kokubili ukukhanya okuphezulu nokuphila isikhathi eside kwesevisi. Idizayini enama-stack ama-5 isabalalisa umthwalo wokusebenza kuyo yonke ingqimba ekhiphayo, iphakamisa ngempumelelo ukukhanya kwesikrini, yandise impilo yesevisi, futhi inciphise kakhulu ukugcinwa kwesithombe - okwenza kube kufanelekile izidingo zokusetshenziswa kwedivayisi yedeskithophu.

Noma kunjalo, ubuchwepheshe bunezinkinga ezicacile. Isakhiwo esikhipha ukungcola esinezingqimba eziningi sandisa ukusetshenziswa kwezinto eziphilayo futhi siphakamisa ubunzima bobuchwepheshe bokumboza ngomhwamuko, okukhuphula ngqo izindleko zokukhiqiza. Ukuthola ibhalansi phakathi kokusebenza, isivuno kanye nezindleko zokukhiqiza kuseyinselele eyinhloko ye-R&D ye-LGD.

Imithombo ikhombisa ukuthi i-Apple ikhiphe izidingo ze-iMac OLED display R&D kokubili ku-LGD kanye ne-Samsung Display ngonyaka odlule, icacisa iphaneli engama-intshi angu-24 enokukhanya okungu-600 nits kanye nobuningi bamaphikseli angu-218 e-PPI. I-Samsung iphinde yakha amaphaneli e-QD-OLED aklanyelwe i-iMac, kanti abakhiqizi bobabili bathuthukisa ukuthengiswa kobuchwepheshe ngasikhathi sinye. Ukuqagela kwemboni kusikisela ukuthi amaphaneli e-OLED avela kubakhiqizi bobabili azoqeda i-R&D ngo-2028. I-iMac yesizukulwane esisha enezibonisi ze-OLED ezintsha izokhishwa ngokusemthethweni ekuqaleni kuka-2029, futhi kulindeleke ukuthi ishintshe isimo semakethe yesikrini sedeskithophu se-LCD yendabuko.
