I-HDR isistimu yakamuva kuzikrini ze-LED 

Ingabe usuzothenga isikrini se-LED futhi awazi ukuthi libaluleke kangakanani igama elithi HDR, (High Dynamic Range, ngesifinyezo salo ngesiNgisi)?

Ungakhathazeki, lapha sizokuchazela.I-HDR, ngamafuphi, ingxenye yesikrini sakho se-LED enesibopho sokuletha izigcawu ezinemibala engokoqobo nokugqama okuphezulu.

Ukugqama kukalwa ngomehluko phakathi kwabamhlophe abakhanya kakhulu nabamnyama kakhulu abangaboniswa isikrini se-LED, kukalwa ngekhandela imitha yesikwele (cd/m2): lokho okubizwa nge-NITS.

Kunamafomethi amaningi ku-HDR, kodwa okwamanje kukhona abadlali ababili abakhulu: ifomethi ye-Dolby Vision yokuphathelene, kanye ne-HDR10 evamile evulekile.U-Dolby ube ngowokuqala ukujoyina iphathi nge-prototype TV ekwazi ukubonisa ukukhanya okungafika ku-4,000 nits.Isikhathi esifushane, i-Dolby Vision empeleni yayifana ne-HDR, kodwa akubona bonke abakhiqizi ababefuna ukulandela imithetho ye-Dolby (noma ukukhokha imali yabo), futhi abaningi baqala ukusebenzela ezinye izindlela zabo.

Amafomethi amabili amakhulu we-HDR asebenzisa imethadatha egijima kusiginali yevidiyo ngentambo ye-HDMI, imethadatha evumela ividiyo engumthombo ukuthi“tshela”isibonisi se-LED indlela yokubonisa imibala.I-HDR10 isebenzisa indlela elula: ithumela imethadatha ngesikhathi esisodwa nasekuqaleni kwevidiyo, isho okuthile okufana nokuthi, "Le vidiyo ifakwe ikhodi kusetshenziswa i-HDR, futhi kufanele uyiphathe ngale ndlela."

I-HDR10 isidume kakhulu kulawa mafomethi amabili.Ngaphezu kwakho konke, iyindinganiso evulekile: abakhiqizi bezikrini ze-LED bangayisebenzisa mahhala.Kubuye kunconywe i-UHD Alliance, evame ukukhetha amazinga avulekile kumafomethi okuphathelene afana ne-Dolby Vision.
