I-1080p imele imigca eyi-1,080 (okanye imigqa yepikelel) iboniswe ngokulandelana kwesikrini seTV. Ngamanye amagama, yonke imigca okanye imigqa yepikseli ichithwa okanye iboniswa ngokuqhubekayo . Yintoni emele imilinganiselo yee-1,920 kwi-skrini kunye neeplayseli eziyi-1,080 ezivela phezulu ukuya phezulu ngaphasi komgca okanye umgca wepikelli uboniswe ngokulandelelana emva komnye. Ukufumana inani leepekseli ezipheleleyo eziboniswe kwindawo yonke yeskrini, ukwandisa i-1,920 x1,080, elinganayo nama-2,073,600 okanye malunga nama-megapixel ayi-2.1.
Yintoni ebizwa ngokuba yiConferencing njenge-1080p TV
I-TV ingabalwa okanye ithengiswe njengeTV ye-1080p ukuba ingabonisa imifanekiso yevidiyo elandela imigaqo engentla.
Iindidi zobuchwepheshe beTV ezixhasa ukuveliswa kweTV ezibonisa iimifanekiso zengcaciso ye-1080p ziquka iPlasma , i- LCD , i- OLED kunye ne- DLP .
QAPHELA: zombini i-DLP kunye ne-Plasma TV ziyekekile kodwa zisetyenziswe kule nqaku kulabo ababenabo, okanye baqhube kwiyunithi esetyenziswayo yokuthenga.
Ukuze i-TV ye-1080p ibonise iimpawu zokusombulula ezantsi, njenge- 480p , 720p, kunye ne-1080i kufuneka iphakamise ezo zimpawu ezingena kwi-1080p. Ngamanye amazwi, ukuboniswa kwe-1080p kumabonakude kunokwenziwa ngokukhawuleza kwangaphakathi okanye ngokuvuma isalathisi esingenayo ye-1080p.
1080p / 60 vs 1080p / 24
Phantse zonke ii-HDTV ezamkela isalathisi se-1080p ngokuzodwa ziyakwamkela oko kwaziwa ngokuba ngu-1080p / 60. I-1080p / 60 ibonisa isignali ye-1080p idluliselwe kwaye iboniswe kwisantya sama-ozimele ezingama-60 ngeyesibili (ama-30 ozimele, kunye nesakhelo esiboniswe kabini ngesibini). Oku kubonisa isisindo sevidiyo se-pixel esiphezulu esingu-1920x1080 yepikseli.
Nangona kunjalo, ngokuza kwe-Blu-ray Disc, "ukutshintsha" kwe-1080p kwaqaliswa kwakhona: 1080p / 24. Yiyiphi i-1080p / 24 imele ireyithi yesreyimu yefilimu eqhelekileyo ye-35mm idluliselwe ngqo kwiimifanekiso ezingama-24-yesibini kwimizi evela kumthombo (njengefilimu kwi-disc-Blu-ray). Ingcamango kukunika umfanekiso okhangelekileyo kwifilimu.
Oku kuthetha ukuba ukuze kuboniswe umfanekiso we-1080p / 24 kwi-HDTV, i-HDTV kufuneka ibe nokukwazi ukufumana ingcamango ye-1080p kwisigqibo sama-24 ngeesibini. Kwiimabonakude ezingenalo lwazi, bonke abadlali be-Blu-ray Disc bangasetyenziselwa ukuvelisa i-720p, 1080i, okanye iimpawu ze-1080p / 60, kwaye, kwiimeko ezininzi, umdlali we-Blu-ray Disc uza kubona isisombululo / isakhelo esifanelekileyo izinga ngokuzenzekelayo.
I-720p TV Conundrum
Enye into ekufuneka abaxhasi baqaphele ukuba yiTVs ezingamkela isignali yenkxaso ye-1080p kodwa ingaba nesisombululo se-pixel sokuzalwa esingaphantsi kwe-1920x1080. Ngamanye amagama, ukuba uthenge iTV nge-1024x768 okanye i-1366x768 isisombululo se-pixel esizalwayo (esakhuthazwa njengee-TV ze-720p), oko kuthetha ukuba ezo iTV ziyakubonisa kuphela loo nombolo yeepekseli kwisikrini, zihamba ngokuzenzekelayo kwaye zenzeke. Ngenxa yoko, umabonwakude onokuzalwa 1024x768 okanye isisombululo se-pixel ye-1366x768 kufuneka uhlawule umqondiso we-1080p ongenayo ukuze ubonise loo mqondiso kwisikrini njengomfanekiso.
Kubalulekile ukuba uqaphele ukuba ezinye ii-TV ze-720p ezamkelekileyo aziwamkeli iimpawu zokufakelwa kwe-1080p, kodwa ziya kwamkela iimpawu zokufakelwa eziyi-1080i. Inani leephikseli ezingenayo lifanayo, kodwa zinegalelo kwifom ye-interlaced (uluhlu ngalunye lweepikseli zithumela ngenye indlela ngendlela engavumelekanga / ngokulandelelana), kunokuba ifomathi iqhubekele phambili (umgca ngamnye wepixel uthunyelwa ngokulandelelana). Kule meko, i-TV ye-720p ayinakudlulisela kuphela uphawu lwangenayo kodwa kufuneka "idibanise" okanye uyiguqule umfanekiso ohamba phambili ube ngumfanekiso oqhubekayo ukuze ubonise umfanekiso kwiskrini.
Yintoni oku kuthetha ukuba ukuba uthenge iTV nge-1024x768 okanye i-1366x768 isisombululo se-pixel somthonyama, oko kuyisimo sesisombululo oza kubona kuso kwisikrini; umfanekiso we-1920x1080p uza kuhlaselwa kwi-720p okanye umfanekiso we-480i uza kuphakanyiswa kwi-720p. Umgangatho wesiphumo uya kuxhomekeka ekusebenzeni kakuhle kweesekethe zokucubungula kwi-TV.
4K Factor
Enye into ekufuneka ithathelwe ingqalelo kukho ukufumaneka kwemithombo yomxholo yesisombululo esingu-4K . Kubalulekile ukubonisa ukuba ngaphandle kweSharp Quattron Plus iiseti (ezingasabikho) , ii-TV ze-1080p azikwazi ukufumana izibonakaliso zokufaka iziphakamiso ze-4K. Ngamanye amagama, ngokungafani nama-480p, 720p, kunye nee-1080i zokufaka iimpawu, apho i-TV ye-1080p inokukhula kwaye idibanise ukulungelelanisa ukuboniswa kwesikrini, abanako (ngaphandle ngaphandle kokuphawula) bayamkela isignali yevidiyo yesisombululo se-4K kwaye bayilinganise ukubonisa isikrini.
Ngaphantsi
Nangona kukho iiTV ezifumanekayo ngezigqibo ezahlukahlukeneyo zokubonisa izityalo, njengomthengi, ungavumeli oku kukudibanise. Hlalani nikhumbule indawo okhoyo ukuba ubeke iTV yakho, iintlobo zemithombo yevidiyo onayo, uhlahlo lwabiwo-mali, kwaye ke, ukuba imifanekiso oyibonayo ibonakala kuwe.
Ukuba ucinga ukuthenga i-HDTV encinci kuneengama-intshi ezingama-40, ulwahlulo olubonakalayo phakathi kwezi zigqibo ezintathu eziphambili ze-definition-definition, 1080p, 1080i, kunye no-720p zincinci xa zibonakala.
Ikhudlwana ubukhulu bekrini, ngakumbi kubonakala umahluko phakathi kwe-1080p nezinye izigqibo. Ukuba ucinga ukuthenga i-HDTV kunye nobukhulu bekrini eziyi-intshi ezingama-40 okanye ezinkulu, kukulungele ukuya ku-1080p ubuncinane (nangona kukho i-TV ye-1080p eninzi ekhoyo kwiiskrini ezingaphantsi kwama-intshi ama-40). Kwakhona, qwalasela ii-4K Ultra HD kwiikrini ezinobungakanani bee-intshi ezingama-50 nangaphezulu (nangona kukho ii-TV ze-4K ze-HD eziqala kwi-screen-size intsuku ezingama-40 intshi).
Ngolwazi olongezelelweyo malunga ne-1080p, ngokukodwa ukufana kwalo kunye neentlukwano kunye ne-1080i, kwakunye noko ufuna ukufumana kakhulu kwi-HDTV yakho, khangela amaphepha am kunye nam: ama- 1080i no-1080p kunye neento ozifunayo kwi-HDTV .
Ukuba uthengisa i-TV entsha, khangela iingcebiso zethu ze- LCD 1080p kunye ne-LED / i-LCD iiTesenti ezingama-40 kunye ne-Larger , 720p kunye ne-1080p 32 ukuya kwi-39 intshi ye-LCD kunye ne-LED / i-LCD yeTV kunye nee- TV ze- 4K ze-HD.
