1080p waxay u dhigantaa 1,080 xariiq (ama safafyada pixel) oo si joogta ah loogu soo bandhigay shaashadda TV-ga. Si kale haddii loo dhigo, dhammaan xariiqyada ama safafyada pixel waxaa lagu sawiray ama lagu soo bandhigayaa si tartiib ah . Maxaa matalaya waa 1,920 pixels shaashadda oo dhan iyo 1,080 pixels oo ka socoda sare ilaa hoose iyada oo xariijin kasta ama lineka pixel lagu soo bandhigay midba midka kale ka dib. Si aad u hesho tirada wadarta pixels ee lagu soo bandhigay aag dhan oo aad ku dhufatay 1,920 x1,080, taas oo u dhiganta 2,073,600 ama qiyaastii 2.1 megawatt.
Waa maxay Saameynta 1080p TV
Telefishin waxaa loo kala saari karaa ama lagu iibin karaa TV-ga 1080p haddii ay muujin karto sawirro muuqaal ah oo ka dambeeya sharciyada kor ku xusan.
Noocyada teknooloojiyada TV-yada ee taageeraya samaynta tv-yada oo muujin kara 1080p image-ga xalalka waxaa ka mid ah Plasma , LCD , OLED , iyo DLP .
FIIRO GAAR AH: TV-yada DLP iyo Plasma labadaba waa la joojiyay, laakiin weli waxaa loo gudbiyaa qodobkan iyaga u gaar ah, ama u adeegsanaya cutub loo adeegsaday iibka.
Si TV-yada 1080p ay u muujiyaan calaamadaha muuqaalka hoose ee hoose, sida 480p , 720p, iyo 1080i waa inay kor u qaadaan calaamadaha soo socda ee 1080p. Si kale haddii loo dhigo, 1080p ayaa ku soo bandhigaya telefishinka waxaa lagu sameyn karaa cabir gudaha ah ama iyadoo aqbalaysa signalka tooska ah ee 1080p.
1080p / 60 vs 1080p / 24
Ku dhowaad dhamaanba HDTV-yada aqbalaan signalka 1080p si toos ah u aqbalaan waxa loo yaqaan 1080p / 60. 1080p / 60 waxay u dhigantaa 1080p signal ah oo loo wareejiyay oo lagu muujiyay heerkul dhan 60 jibbaar midkiiba (30 wadiiqo, oo leh shaxda lagu soo bandhigay laba jeer halkii labaad). Tani waxay ka dhigan tahay sawirka qalabka casriga ah ee 1920x1080 pixel video.
Si kastaba ha noqotee, iyadoo ay soo ifbaxday Blu-ray Disc, "kala duwanaansho" oo ah 1080p ayaa sidoo kale la hirgeliyey: 1080p / 24. Waa 1080p / 24 u taagan yahay qaabka wareega ah ee 35mm filimaad toos ah oo toos ah loogu wareejiyay 24-kii ilbidhiqsi-ilbiriqsi (sida filim ku sawiray Blu-ray). Fikradda waa in sawir laga dhigo muuqaal filim oo dheeraad ah.
Tani waxay ka dhigan tahay in si loo soo bandhigo 1080p / 24 image HDTV, HDTV waa inuu leeyahay awood uu ku aqbalo fikradda 1080p oo qura 24 gogoqsi halkii labaad. TV-yada aan lahayn karti-xirfadeedkan, dhammaan ciyaartoyda Blu-ray Disc ayaa sidoo kale lagu soo saari karaa 720p, 1080i, ama 1080p / 60 signals, iyo, xaalado badan, ciyaaryahaanka Blu-ray Disc ayaa ogaan doona xalinta habboon si toos ah u dhiganta.
Telefishinka 720p
Waxyaabaha kale ee macaamiishu u baahan yihiin inay ka warqabaan waa TV-yada laga yaabo in ay aqbalaan signalka 1080p, laakiin waxaa laga yaabaa in qiyaasta pixel-ka ee dhab ahaantii ka hooseeya 1920x1080. Haddii si kale loo dhigo, haddii aad iibsaneyso TV oo leh 1024x768 ama 1366x768 qiyaasta pixel pixel (taasoo kor loogu qaado TV-yada 720p), taasi waxay ka dhigan tahay in TV-yadu ay muujin karaan tirada pixels ee shaashadda, oo soconaya horon iyo kareem. Natiijada, TV-ga oo leh asal 1024x768 ama xalinta 1366x768 pixel waa inuu hoos u dhigaa signalka soo socda ee 1080p si loo muujiyo signalka shaashadda sawir ahaan.
Waxaa muhiim ah in la ogaado in qaar ka mid ah TV-yada 720p aysan aqbalin signalka 1080p, laakiin waxay aqbali doonaan signallada 1080i. Tirada jajabyada soo galaya waa isku mid, laakiin waxay ku dhex jiraan qaab isku duuban (mid kasta oo ka mid ah pixels ayaa mar labaad u diraya shaksi / xitaa isku xigxig), halkii uu ka muuqan lahaa qaab isbarbardhigi ah Xaaladdan, TV-ga 720p ma aha oo kaliya in ay kor u qaadaan signalka soo socda, laakiin waa inay sidoo kale "kala-soocaan" ama u bedelaan muuqaalka iskudhaca ee muuqaalka sawirada si loo muujiyo sawirka shaashadda.
Taas oo dhan micnaheedu waa in haddii aad iibsato TV ah oo leh 1024x768 ama 1366x768 xal pixel native, taas oo ah image xal aad ka arki doontaa shaashadda; sawir 1920x1080p ah ayaa hoos loogu dhigi doonaa 720p ama 480i image ayaa lagu sari doonaa ilaa 720p. Tayada natiijadu waxay ku xiran tahay sida fiican ee wareegga fiidiyoo fiidiyoogu uu ku jiro TV-ga.
Xaaladda 4K
Waxyaabo kale oo la tixgelinayo waa helitaanka ilaha content ee 4K . Waxaa muhiim ah in la tilmaamo in, marka laga reebo Sharp Quattron Plus (oo aan hadda la heli karin) , 1080p TVs ma aqbali karaan signallada 4K ee qaraarka. Si kale loo dhigo, marka laga reebo 480p, 720p, iyo 1080i calaamadaha muuqaalka, kaas oo ah 1080p TV-yada oo kor u qaadi kara oo lagu daro bandhigida shaashadda, ma awoodi karaan (marka laga reebo marka laga reebo xusuusta) aqbalaan calaamad muuqaal ah oo 4K ah oo kor u qaadaya bandhigga shaashadda.
Khadadka hoose
Inkasta oo ay jiraan TV-yada lagu heli karo qaraaro soo bandhigid kala duwan, macaamiil ahaan, ha u ogolaan in tani ay isku qasanto. Maskaxda ku hay meesha aad haysato si aad u dhigto tv-gaaga, noocyada ilaha fiidiyowga ah ee aad haysato, miisaaniyadaada, iyo, dabcan, sida sawirada aad u aragtid adiga.
Haddii aad ka fekereyso iibka HDTV ka yar 40 ilbiriqsi, farqiga muuqda ee u dhexeeya saddexda qawaaniinta qeexaya ee sarreeya, 1080p, 1080i, iyo 720p waa wax aad u yar haddii la dareemo.
Baaxadda weyn ee muraayadda, inta badan la ogaan karo faraqa u dhexeeya 1080p iyo qaraarada kale. Haddii aad ka fekereyso inaad iibsato HDTV leh cabir weyn oo ah 40-inch ama ka weyn, waxaa ugu fiican in aad u tagto 1080p ugu yaraan (inkastoo ay jiraan tiro badan oo ah 1080p TV-yada lagu heli karo cabbirrada shaashadda oo ka yar 40-inch). Sidoo kale, tixgelin 4K Ultra HD TV-yada sawirada 50-inji iyo ka weyn (inkastoo ay jiraan 4K Ultra HD TV-yada oo ku bilaabmaya qiyaasta 40-inch).
Macluumaad dheeri ah oo ku saabsan 1080p, gaar ahaan muuqaalkiisa iyo kala-duwanaanta 1080i, iyo sidoo kale waxa aad u baahan tahay inaad ka heshid HDTV-gaaga, hubi maqaaladayda asxaabta ah: 1080i vs 1080p iyo Maxaad u Baahan Tahay Inaad Soodhawrto Heerka Hore ee HDTV .
Haddii aad soo iibsato TV cusub, fiiri talooyinkeena 1080p LCD iyo LED / LCD TVs 40-inch iyo Larger , 720p iyo 1080p 32 illaa 39-inch LCD iyo TV-yada / LCD , iyo 4K Ultra HD TVs.
