I-HDR ihlobene eduze nokukhanya. Izinga le-HDR ST2084 1000 libonakala ngokugcwele uma lisetshenziswa ezikrinini ezikwazi ukufeza ukukhanya okuphezulu kwe-1000 nits.

Ezingeni lokukhanya kwe-1000 nits, umsebenzi we-ST2084 1000 wokudlulisa i-electro-optical uthola ibhalansi ekahle phakathi kokubona komuntu kanye nekhono lobuchwepheshe, okuholela ekusebenzeni okuvelele kobubanzi obuphezulu (HDR).

Ngaphezu kwalokho, amamonitha anokukhanya okuphezulu okungu-1000 nits angase asebenzise ngokugcwele izici zombhalo zekhodi ze-ST2084 curve's logarithmic. Lokhu kuvumela ukuphindwaphindwa okunembile kwezithombe ezinhle kakhulu ezikhethekile nemithelela yokukhanya kwelanga esondela kumaleveli wokuqina womhlaba wangempela, nokugcina imininingwane yethunzi ezindaweni ezimnyama. Ububanzi obuguquguqukayo obunyukile buvumela izithombe zibe yingcweti ku-1000 nits HDR ukuze zibonise ukuthungwa nama-gradient ebezingacindezelwa noma zilahleke ezimweni zokukhanya okuncane.

I-1000 nits threshold ichaza indawo emnandi ebalulekile yokusetshenziswa kokuqukethwe kwe-HDR ST2084 1000. Ihlinzeka ngokukhanya okuphezulu okwanele ukuze inikeze izilinganiso zokungafani ezimangalisayo ezingaphezu kuka-20,000:1 uma kuhlanganiswa nokushona okumnyama kwezinga le-OLED. Ngaphezu kwalokho, ama-1000 nits ahlala engaphansi kwemikhawulo esebenzayo yobuchwepheshe bokubonisa abathengi kanye nokusetshenziswa kwamandla esimweni sokusebenza okuphezulu. Le bhalansi iqinisekisa ukuthi inhloso yobuciko yabaqondisi iyagcinwa kuyilapho ihlinzeka abasebenzisi ngolwazi lokubuka olunethezekile.

Lapho ufunda kahle izithombe ze-ST2084, izitudiyo zokukhiqiza ezichwepheshile zivame ukusebenzisa iziqaphi zokukhiqiza eziyi-1000 ngoba azihlanganisi iningi lezilungiselelo zokubuka zomhlaba wangempela kodwa futhi ziqinisekisa ukuhambisana okubuyela emuva neziqaphi zokukhanya okuphansi kusetshenziswa imephu yethoni. Umphumela uyisithombe se-HDR esigcina umthelela waso obonakalayo kuzo zonke izinto zokusebenza ngaphandle kokudela umbono womenzi wefilimu.

Okokugcina, inhlanganisela yamakhono okubonisa angu-1000 nits kanye nezinga le-ST2084 1000 liwukuphezulu kwamanje kokuqaliswa kwe-HDR, okuhlinzeka ababukeli ngesipiliyoni esibonakalayo esigxilile esivala igebe phakathi kokuqukethwe kwedijithali nokubona okubonakalayo komuntu okungokwemvelo.
