I-8K TV – kuyini

Ngakho yini i-8K TV futhi ihluke kanjani ku-4K evamile kanye ne-Full HD? Igama elithi “8K”, elibhekisela ekuthuthukisweni okusha ekuxazululeni, i-cinema yedijithali kanye nehluzo zekhompyutha, ezihambisana namaphikseli acishe abe ngu-8,000, yethulwa okokuqala ngo-2013. Kodwa-ke, ngaleso sikhathi, isivinini seziteshi ze-inthanethi asizange simelele ukuthi kungenzeka ukudluliswa kwedatha. Ngakho-ke, ubuchwepheshe be-8K busekelwe ekusakazweni kwesathelayithi ukuhlinzeka ngokudluliswa kwedatha. Ukuthandwa kwalolu hlobo lwethelevishini kwaqala ngo-2018, okube nomthelela omuhle ekwakhekeni kwamazinga e-TV esizukulwane esisha.
I-8K TV iyimodeli yesizukulwane yakamuva enokulungiswa okuphezulu kakhulu. Umehluko omkhulu kusukela esizukulwaneni esinesixazululo se-4K ukukhiqizwa okunembe kakhudlwana kwama-nuances amancane. I-8K ingaphezu kwezigidi ezingu-33 zamaphikseli (amaphikseli angu-7680×4320), okukuvumela ukuthi ubone zonke izinwele ezingutsheni. Uma kuqhathaniswa, kusikrini se-4K, inani lamaphikseli cishe li-3840×2160. Isilinganiso senani lamaphikseli sibonisa ngokucacile umehluko:

• 8K – 33 million;
• 4K – 8 million;
• I-HD Egcwele – 2 million.
