Ukuboniswa kwe-Retina yigama elinikezwe i-Apple ebuchwepheshe bokubukwa kweskrini esiphezulu esetshenziswa kumamodeli ahlukahlukene e-iPhone, iPod touch, nezinye imikhiqizo ye-Apple. Iqaliswe ne-iPhone 4 ngoJuni 2010.
Kuyini Ukubuyisa Ukubuyisa?
Ukubukwa kwe-Retina kuthola igama layo kusuka ekumangeleni kwe-Apple ukuthi izikrini ezenziwe ngokusebenzisa ubuchwepheshe zibukhali futhi ziphakeme kakhulu kangangokuthi akunakwenzeka ukuba iso lomuntu lihlukanise amaphikseli athile.
Ukubuyiselwa kwe-Retina kususa izingxenyana ezinama-pixels ezakha izithombe ezikrinini futhi zenza izithombe zibukeke ngokwemvelo kakhulu.
Izinzuzo zobuchwepheshe ziyabonakala ekusetshenzisweni okuningi, kodwa ngokukhethekile ekuboniseni umbhalo, lapho izingqimba ezigobile zefonti zilula kakhulu kunokuba ubuchwepheshe bokubonisa bokuqala.
Izithombe ze-Retina Display zekhwalithi eziphezulu zisekelwe ezintweni eziningi:
- Ukuphakama okukhulu kwamaphikseli akha isikrini sedivayisi.
- Isilinganiso esiphakeme sokuhlukanisa abamhlophe nabamnyama abajulile.
- Ubuchwepheshe be-In-Plane Switching (IPS) ukuthuthukisa ama-angles lapho isikrini singabonwa khona.
- Ilazi eliphathwa ngamakhemikhali phezu kwesibuko kanye nokukhanyisa kwe-LED ukuthuthukisa ikhwalithi yesithombe.
Izinto Ezibili Ezikwenza Isikrini Sokubonisa I-Retina
Nakhu lapho izinto zithokozisa kancane: Asikho isinqumo sekrini esisodwa esenza isikrini se-Retina Display.
Isibonelo, awukwazi ukusho ukuthi yonke idivayisi enezixazululo zamaphikseli angu-960 x 640 ane-Retina Display, noma ngabe yisisombululo se- iPhone 4 , esineskrini sokubuyisa se-Retina.
Esikhundleni salokho, kunezici ezimbili ezakha isikrini sokubuyisa se-Retina: ukuphakama kwephikelini nebanga okuvela kuso isikrini.
Ubuningi bePixel bubhekisela ekusebenzeni ngokuqinile kwamaphikseli kwesikrini. Ukwanda okukhulu, kushisa izithombe. Ukuphakama kwe-pixel kulinganiswa ngamaphikseli ngamasentimitha ngamasentimitha, noma i-PPI, ekhombisa ukuthi zingaki amaphikseli akhona ku-inch eyodwa intshi yeskrini.
Lokhu kusekelwe ekuhlanganisweni kwesinqumo sedivaysi nosayizi wayo wesimo.
I-iPhone 4 yayinombukiso we-326 we-PPI kwisikrini sesisindo esingu-3.5-intshi nesisombululo esingu-960 x 640. Lokhu kwakuyi-PPI yangempela ye-skrini ye-Retina Display, nakuba lokho kwashintsha njengamakhodi wakamuva adedelwe. Ngokwesibonelo, i- iPad Air 2 inesibuko se-pixel esingu-2048 x 1536, okuholela ku-264 PPI. Lokho, futhi, yisikrini sokubuyisa se-Retina. Yilapho isici sesibili singena khona.
Ukubuka ibanga libhekisela ekutheni abasebenzisi kude kangakanani babamba idivayisi ebusweni babo. Isibonelo, i-iPhone ngokuvamile ibanjwe ngokuseduze ubuso bomsebenzisi, kuyilapho i-Macbook Pro ibonakala ngokuvela kude. Lokhu kubalulekile ngoba isici esichazayo se-Retina Display ukuthi amaphikseli akakwazi ukuhlukaniswa ngeso lomuntu. Okuthile okubonwayo okusondela kakhulu kudinga ukuphakama okukhulu kwamaphikseli ukuze iso lingaboni amaphikseli. Ukuphakama kwe-pixel kunganciphisa izinto ezibonakala kude.
Amanye amagama we-Retina Display
Njengoba i-Apple isungule amadivaysi amasha, ubukhulu beskrini, nezinkinga zamaphikseli, seliqalile ukusebenzisa amanye amagama ngokubukeka okuhlukile kwe-Retina. Lokhu kufaka:
- I-Retina Display- isetshenziswe ku-iPhone 4, phakathi kwabanye.
- I-Retina HD Display- isetshenziswa kwi- iPhone 6 Plus , nabanye.
- Ukubukwa kwe-Retina engu-4K- kusetshenziswe ku-iMac engu-21 intshi.
- I-retina ye-5K Display- isetshenziswe ku-iMac engu-27 intshi.
- I-Super Retina HD Display- isetshenziswe ku- iPhone X.
Imikhiqizo ye-Apple ene-Retina Display
Ukubukwa kwe-Retina kuyatholakala kumikhiqizo elandelayo ye-Apple, ezinqumweni ezilandelayo kanye nokucindezeleka kwe-pixel:
