8K yog qhov kev daws teeb meem ntawm 7,680 ×4,320 pixels (16: 9) (kwv yees li 33 lab pixel duab ib thav duab).Qhov no tsis yog lub ntsiab lus tshiab.Raws li thaum ntxov Lub Yim Hli 23, 2012, International Telecommunication Union nyob rau hauv United Nations tau txais 76 lab kev daws teeb meem pom zoo los ntawm Nyiv lub chaw nres tsheb NHK TV raws li thoob ntiaj teb 8K super-txhais TV (SHV) tus qauv.Tus neeg siv lub tswv yim ntawm kev daws teeb meem tseem tsis meej.Nov yog qhov rov hais dua ntawm cov kev paub txog kev daws teeb meem hauv lub neej:
Hauv Suav teb, hom ntawv TV yog hom PAL, thiab qhov kev daws teeb meem dav dav yog 720 * 576 pixels.Feem ntau cov TVs zoo tib yam siv interlaced scanning nrog tus nqi ntawm 25 thav duab ib ob, tab sis qhov system no tau raug tshem tawm.Tam sim no muaj qee yamhigh-txhais TV programraws, thiab qhov kev daws teeb meem ntawm lub vijtsam tuaj yeem ncav cuag 2048x1080 lossis 2K, uas tseem hu ua 1080P.Txawm hais tias qhov kev daws teeb meem ultra-clear channel mus txog 4096x2160 pixels, nrog tsawg kawg ntawm 60 ntas ib ob.Piv txwv li, Tuam Tshoj Central Xov tooj cua thiab TV qhov kev pab cuam 4K tau tshwm sim ntawm ob zaug.
Rau cov neeg uas koom nrogLED kev lag luam, lawv tsis paub txog kev daws teeb meem.Feem ntau ntawm qhov loj me me-pitch screen project case lossis sab nraum qhov project peb tau kawm dhau qhov kev daws teeb meem ntawm 4K lossis 8K.LED zaub thev naus laus zis muaj qhov zoo dua li lwm cov khoom siv thev naus laus zis, vim tias lawv tuaj yeem ua rau qhov kev daws teeb meem ntawm qhovzaub screenloj txaus yam tsis txwv thaj chaw.Lub pem hauv ntej-kawg tsuas yog xav tau splice ntau daim npav duab, thiab tom qab ntawd synchronously splice lawv los ntawm video processor, txawm tias qhov kev daws teeb meem siab npaum li cas.
Tom qab ntawd, raws li lub ntsiab lus ntawm qhov kev daws teeb meem saum toj no, cia peb hla nws dua.8K video yuav tsum muaj qhov kev daws teeb meem ntawm 76804320, uas txhais tau hais tias qhov kev daws teeb meem ntawm txhua tus ncej (uas yog, txhua qhov screen) ntawm qhov video yuav tsum ua tiav.Los ntawm daim npav graphics Cov zis yog ib daim duab ntawm 120 ntas ib ob.Xws li ib tug loj npaum li cas ntawm cov vis dis aus yuav tsum muaj 8K lub koob yees duab los tua ua ntej.Qhov thib ob yog kom tau txais cov yeeb yaj kiab loj dua los ntawm kev siv tshuab hluavtaws hluavtaws.
Qhov tseeb, raws li tus neeg muag khoom LED zaub, peb lub hom phiaj yog kom coj cov neeg siv khoom noj ib txwm muaj, thiab qhia cov chaw sib txawv kom siv cov kev daws teeb meem sib txawv.Los ntawm qhov pom qhov deb ntawm qhov screen rau cov neeg tuaj saib, yog tias koj tsis tuaj yeem hnov qhov graininess ntawm pixels ntawm lub vijtsam zaub, nws yuav ua tau raws li cov kev xav tau ntawm cov neeg siv.Cov khoom siv hluav taws xob tau hloov kho thiab rov ua dua nrawm dua, thiab qhov loj dua ntawm thaj chaw, lub zog siv ntau dua.Nws yog ib qho khoom kim heev thiab pov tseg kom dhau qhov kev xav tau ntawm cov neeg siv khoom.
Yog lawm, yog hais tias tus neeg siv tej yam kev mob yog superior, nyob rau hauv niaj hnub era ntawm kev siv technology tshiab, ultra-high-txhais yees duab yuav maj mam mus txog rau tib neeg pom.
