I-QLED vs. UHD: Uthelekiso olugqibeleleyo

Inkqubela phambili yethekhnoloji iye yazisa iintlobo ezininzi zetekhnoloji yokubonisa, kwaye i-QLED kunye ne-UHD ziphakathi kwabameli. Ziziphi iimpawu zabo ezizodwa? Eli nqaku liza kuxubusha ngokunzulu imigaqo yobugcisa, iimpawu kunye neemeko zesicelo se-QLED vs. UHD. Ngothelekiso oluneenkcukacha kunye nokutolika, kuya kukunceda ukuba uqonde ngcono ezi teknoloji zimbini zokubonisa.

1. Yintoni i-QLED?

I-QLED (i-Quantum Dot Light Emitting Diodes) yenziwe ngamachaphaza e-quantum ebizwa ngokuba yi-physicist Mark Reed yaseYunivesithi yaseYale. Ngokukodwa, ibhekisa kwiinanocrystals ezincinci kakhulu zesemiconductor ezingabonakaliyo ngeso lenyama. I-QLED yitekhnoloji yokubonisa esekwe kwitekhnoloji ye-quantum dot. Ngokongeza umaleko we-quantum dot material phakathi kwemodyuli ye-backlight kunye nemodyuli yomfanekiso wesiboniso se-LED, inokuphucula ukucoceka kombala wesibane esingasemva, okwenza imibala ebonisiweyo icace ngakumbi kwaye ithambile. Ngexesha elifanayo, inokukhanya okuphezulu kunye nokuchasana, ukubonelela ababukeli ngolwazi olungcono lokubonwayo.

2. Yintoni i-UHD?

Igama elipheleleyo le-UHD yi-Ultra High Definition. I-UHD yiteknoloji yesizukulwana esilandelayo se-HD (inkcazo ephezulu) kunye ne-HD egcweleyo (iNkcazo ePhezulu ePheleleyo). Ngokuqhelekileyo ibhekisela kwifomathi yokubonisa ividiyo enesisombululo se-3840 × 2160 (4K) okanye 7680 × 4320 (8K). Ukuba sithelekisa i-HD (iNgcaciso ePhezulu) kunye nomgangatho wesithombe se-movie eqhelekileyo, i-FHD (iNkcazo ePhezulu ePheleleyo) ifana nenguqu ephuculweyo yeefilimu eziphezulu. Ke i-UHD ifana nomgangatho womfanekiso bhanyabhanya onenkcazo ephezulu ngokuphindwe kane kune-FHD. Kufana nokwandisa umfanekiso onenkcazo ephezulu ukuphinda kane ubukhulu bawo kwaye ugcina umgangatho womfanekiso ocacileyo nobuthathaka. Undoqo we-UHD kukubonelela abasebenzisi ngeziphumo ezicacileyo nezithambileyo zomfanekiso kunye nevidiyo ngokunyusa inani leepixels kunye nesisombululo.

3. UHD vs QLED: Yeyiphi eNgcono?

3.1 Ngokwesiphumo sokubonisa

3.1.1 Ukusebenza kombala

I-QLED: Inomsebenzi obalaseleyo wombala. Amachaphaza e-Quantum anokukhupha ukukhanya ngococeko oluphezulu kakhulu kwaye afikelele kumbala ophakamileyo we-gamut. Ngokwethiyori, inokufikelela kwi-140% ye-NTSC yombala we-gamut, ephezulu kakhulu kuneteknoloji yokubonisa i-LCD yendabuko. Ngaphezu koko, ukuchaneka kombala kuphezulu kakhulu, kwaye kunokubonisa imibala ecacileyo kunye neyinyani.
