I-1080p imelela imigqa engu-1,080 (noma imigqa ye-pixel) iboniswa ngokulandelana kwesikrini se-TV. Ngamanye amazwi, yonke imigqa noma imigqa yephikseli iskena noma iboniswa kancane kancane . Lokho okumelela ngamaphikseli angu-1,920 kuwo wonke isikrini namaphikseli angu-1,080 asebenza phezulu ukusuka phezulu kuya phansi ngomugqa ngamunye noma umugqa wepikelel uboniswa ngokulandelana ngokulandelana kokulandelana. Ukuze uthole inani lamaphikseli angqikithi aboniswe endaweni yonke yeskrini ukwandisa i-1,920 x1,080, elingana no-2,073,600 noma cishe ama-megapixel angu-2.1.
Yini ehlukaniswa njenge-TV ye-1080p
I-TV ingahlukaniswa noma ithengiswe njenge-TV ye-1080p uma ingabonisa izithombe zevidiyo ezilandela imithetho engenhla.
Izinhlobo zobuchwepheshe be-TV ezisekela ukwakha ama-TV angabonisa izithombe zezinqumo ezingu-1080p zihlanganisa iPlasma , i- LCD , i- OLED , ne- DLP .
QAPHELA: Zombili i-DLP ne-Plasma TVs isusiwe kodwa isalokhu kukhonjisiwe kulesi sihloko kulabo abababo, noma baqhubekele esakhiweni esetshenziselwa ukuthenga.
Ukuze i-TV engu-1080p ibonise izixazululo ezingezansi zevidiyo, njenge- 480p , 720p, ne-1080i kumele iphakamise lezo zimpawu ezingenayo zibe ngu-1080p. Ngamanye amazwi, ukuboniswa kwe-1080p ku-TV kungenziwa nge-scaling yangaphakathi noma ngokumukela isignali eyi-1080p eqondile.
1080p / 60 vs 1080p / 24
Cishe wonke ama-HDTV avuma isignali yokufaka 1080p ngqo angamukela lokho okuyaziwa ngokuthi ngu-1080p / 60. I-1080p / 60 imelela isignali engu-1080p idluliselwe futhi iboniswe ngesilinganiso sama-ozimele angu-60 ngehora (ama-30 ozimele, ngesakhiwo esiboniswe kabili ngomzuzwana). Lokhu kubonisa isignali yevidiyo ye-pixel ye-1920x1080 yokuqhubekayo evamile.
Noma kunjalo, ngokufika kwe-Blu-ray Disc, ukuhlukahluka "okusha" kwe-1080p nakho kwasetshenziswa: 1080p / 24. Lokho okushiwo ngu-1080p / 24 kumele isilinganiso sefreyimu yefilimu ejwayelekile ye-35mm idluliselwe ngqo kuma-ozimele angu-24-ngomzuzwana angu-24 ukusuka kumthombo (njengefilimu ku-Blu-ray disc). Umqondo ukunikeza isithombe ukubukeka kwe-movie evamile.
Lokhu kusho ukuthi ukuze ubonise isithombe esingu-1080p / 24 kwi-HDTV, i-HDTV kufanele ibe nekhono lokuvuma ukufaka kwesinqumo se-1080p kuma-ozimele angu-24 ngomzuzwana. Ama-TV angenawo amandla, bonke abadlali be-Blu-ray Disc bangasethwa ukuze bakhiphe ama-720p, 1080i, noma amasignali angu-1080p / 60, futhi, ezimweni eziningi, isidlali se-Blu-ray sizobona isinqumo / ifreyimu efanele ukukala ngokuzenzekelayo.
I-720p TV Conundrum
Enye into abathengi kudingeka baqaphele ukuthi yi-TV engayamukela isignali ye-1080p kodwa ingaba nesinqumo sokuzalwa se-pixel esiphezulu esingaphansi kwe-1920x1080. Ngamanye amazwi, uma uthenga i-TV ene-1024x768 noma i-1366x768 isinqumo se-pixel somdabu (okugqugquzelwa njengezingqikithi ze-720p), lokho kusho ukuthi lawo ma-TV angabonisa kuphela leyo nombolo yamaphikseli esibukweni, asebenza ngokuzenzekelayo futhi avele. Ngenxa yalokho, i-TV ene-1024x768 noma isixazululo se-pixel 1366x768 kufanele imise phansi isignali ye-1080p engenayo ukuze ibonise leyo signal kuskrini njengesithombe.
Kubalulekile ukuthi uqaphele ukuthi amanye ama-TV angu-720p amadala awawamukeli izimpawu zokufaka ezingu-1080p, kodwa uzothola izibonakaliso zokufaka ezingu-1080i. Amaphikseli angenayo angenjalo, kodwa afaka amafomethi e-interlaced (umugqa ngamunye wamaphikseli uthumela ngokuhlukile ngendlela engavamile / ngokulandelana), kunokuba ifomethi eqhubekayo (umgqeni ngamunye we-pixel uthunyelwa ngokulandelana). Kulesi simo, i-TV ye-720p ayikona nje kuphela ukukala isignali engenayo kodwa kufanele futhi "i-deinterlace" noma iguqule isithombe esithintekayo sibe umfanekiso oqhubekayo ukuze ubonise isithombe esibukweni.
Konke lokhu kusho ukuthi uma uthengisa i-TV ene-1024x768 noma i-1366x768 isinqumo sokuzalwa se-pixel, lokho kuyisithombe sokuxazulula uzobona esibukweni; isithombe se-1920x1080p sizokwehliselwa ku-720p noma isithombe se-480i sizophakanyiswa ku-720p. Ikhwalithi yomphumela izoncika ekutheni okuhle ukuqhutshwa kwevidiyo ku-TV.
I-Factory ye-4K
Enye into okufanele uyihlolisise ukutholakala kwemithombo yokuqukethwe engu- 4K . Kubalulekile ukukhomba ukuthi, ngaphandle kwe- Sharp Quattron Plus ebekayo (engasatholakali) , ama-TV angu-1080p akakwazi ukwamukela izimpawu zokufaka iziphakamiso ezingu-4K. Ngamanye amazwi, ngokungafani nama-480p, 720p, nama-1080i wokufaka ama-TV, ama-TV angu-1080p angakwazi ukukhipha futhi afake ngokwengeziwe ukulungiswa kokubukwa kwesikrini, abakwazi (ngaphandle kwalapho okuphawulwe khona) bamukela isignali yevidiyo yesinqumo se-4K bese beyibeka phansi ukuze kuboniswe isikrini.
Okubalulekile
Nakuba kukhona ama-TV atholakala ngezinqumo ezihlukahlukene zokubonisa izilwane, njengomthengi, ungavumeli lokhu kudideke. Gcina engqondweni isikhala ositholile ukubeka i-TV yakho, izinhlobo zemithombo yevidiyo onayo, isabelomali sakho, futhi-ke, ukuthi izithombe ozibonayo zibukeka kanjani.
Uma ucabangela ukuthengwa kwe-HDTV encane kunama-intshi angu-40, umehluko wangempela wokubukwa phakathi kwezinqumo ezintathu eziphezulu eziphezulu, izincazelo ezingu-1080p, 1080i, no-720p zimbalwa uma zibonakala.
Ikhudlwana ubukhulu beskrini, ukubonakala okuphawulekayo phakathi kwe-1080p nezinye izinqumo. Uma ucabangela ukuthenga i-HDTV ngosayizi weskrini wama-intshi angu-40 noma ngaphezulu, kungcono ukuya ku-1080p okungenani (nakuba kunezintambo eziningi ze-TV 1080p ezitholakalayo ngobukhulu beskrini obungaphansi kwamasentimitha angama-40). Futhi, cabangela ama-4K Ultra HD ama-TV emasayizi ombukiso amasentimitha angu-50 futhi amakhulu (nakuba kunezingqikithi ze-4K Ultra HD eziqala usayizi weskrini ongama-intshi angu-40).
Ukuze uthole ulwazi oluthe xaxa ngo-1080p, ikakhulukazi ukufana kwalo nokungafani no-1080i, kanye nalokho okudingayo ukuze uthole okuningi kwe-HDTV yakho, hlola izihloko zami zomngane: 1080i vs 1080p nokuthi Yini Okudingekayo Ukuphakamisa Ukuchaza Isinqumo kwi-HDTV .
Uma uthengisa i-TV entsha, hlola iziphakamiso zethu ze- LCD 1080p ne-LED / i-LCD TVs ama-inch angu-40 no-Larger , 720p no-1080p 32 kuya ku-39 intshi yama-LCD kanye ne-LED / i-LCD TV , nama- 4K Ultra HD TV.
