Marka ay timaado TV-yada LCD ( TV-yada LED'ga waa TV-yada LCD! ), Macaamiisha badankood waxay si toos ah u fekeraan in LCD ay u dhiganto HDTV. Si kastaba ha ahaatee, waa in la ogaadaa in erayga "LCD" uusan haysan wax xallin ah, laakiin tiknoolajiyada loo isticmaalo si loo abuuro sawirka lagu arkay shaashadda LCD-ga. Qalabka LCD TV waxaa loo samayn karaa si loo muujiyo qaraar qaas ah, kaas oo lagu sheegay Pixels . Waxaa sidoo kale muhiim ah in la tilmaamo in cabbirka LCD-ga uusan si macquul ah u micnaheedu ahayn inuu yahay HDTV midkood.
Kuwa soo socdaa waa sharraxaad ku saabsan sida isdhexgalka ee tiknoolijiyada casriga ah iyo xalka qeexida.
SDTV iyo EDTV
Haddii aad leedahay LCD TV oo la soo saaray horaanta 2000 ama ka hor, waxaa laga yaabaa inay noqoto SDTV (Standard Definition TV) ama EDTV (Telefishin La Ballaariyey) oo aan ahayn HDTV.
SDTVs waxay qabaan qiyaasta 740x480 (480p). "P" waxay u taagan tahay sawirro horumarineed , taas oo ah qaabka LCD-TV-yada u muuqda pixels iyo sawirrada shaashadda.
EDTVs waxay caadi ahaan leeyihiin qiyaasta pixel-ka caadiga ah ee 852x480. 852x480 waxay u dhigantaa 852 pixels oo dhan (bidix ilaa midig) iyo 480 pixels hoos (sare ilaa hoose) shaashadda. 480 pixels hoos ayaa sidoo kale waxay ka dhigan tahay tirada safafka ama xariiqyada xagga sare ee xagga hoose ee shaashadda. Tani way ka sarreysaa qeexitaanka heerka, laakiin ma buuxinayso shuruudaha qiyaasta HDTV.
Sawirada ku yaala arrimahan ayaa wali si fiican u eegi kara, gaar ahaan DVD-yada iyo cable-ka caadiga ah, laakiin ma ahan HDTV. DVD waa qaabka Qeexida Heerka ay taageerto qaraarka 480i / p (740x480 pixels).
LCD iyo HDTV
Si telefishinada oo dhan (taas oo macnaheedu yahay TV-yada LCD) in lagu aqoonsado sida HDTV, waa inay awoodaan inay muujiyaan xalka tooska ah ugu yaraan 720 xariiq (ama safafada pixel). Qiyaasaha muujinta bandhigyada ee ku habboon shuruuda (pixels) waa 1024x768, 1280x720 , iyo 1366x768.
Sababtoo ah telefishinada LCD waxay leeyihiin tiro sonkor ah oo pixels ah (oo lagu tilmaamayo bandhig sawir leh), calaamadaha signalka ee leh qaraarrada sare waa in la cabiraa si loogu qiyaaso tirada miisaanka pixel ee bandhigga LCD.
Tusaale ahaan, nooca loo yaqaan 'HDTV' nooca 1080i ama 1080p waxay ubaahan tahay sawir muujin ah 1920x1080 pixels si ay u muujiyaan muuqaalka dhibcaha hal-hal-biriqsi HDTV. Sidoo kale, tan iyo markii hore, LCD Televisions waxay muujinayaan oo kaliya sawirada si toos ah loo sawiro, 1080i source signals ayaa had iyo jeer isku daya 1080p ama waxay hoos u dhigeen 768p (1366x768 pixels), 720p, ama 480p taasoo ku xiran qiyaasta pixel native pixel LCD TV .
Si kale haddii loo dhigo, ma jirto wax la mid ah 1080i LCD TV. TV-yada LCD waxay kaliya ku muujin kartaa muuqaal sawir oo ah qaab sawir leh, sidaas darteed haddii LCD TV-gaagu aqbalo signalka 1080i-ga taleefanka, LCD-TV-ga wuxuu u baahan yahay inuu kala-saaro oo uu iska daayo signalka 1080i ee 720p / 768p ee TV-yada leh 1366x768 ama 1280x720 pixel native pixel xallin ama 1080p on TV-yada LCD oo leh qiyaasta 1920x1080 pixel.
Sidoo kale, haddii telefishinka LCD-gaagu leeyahay mashiinka pixel-ka ee 852x480 ama 1024x768, astaamaha asalka ah ee HDTV waa in la cabiraa si loo eego 852x480 ama tirooyinka 1024x768 ee korka muraayadda LCD. Tilmaamaha signalka HDTV waa in la yareeyo si loo taakuleeyo mawduuca Pixel-yada ee Telefishinka.
Ultra HD TV iyo Beyond
Horumarinta tignoolajiyada wax soo saarka, waxaa jira tiro sii kordheysa ee TV-yada LCD-ga ah oo bixiya 4K (3840x2160 pixels) qiyaasta muuqaalka (oo loo yaqaan Ultra HD).
Sidoo kale, TV-yada taageeri kara 8K xal (7680 x 4320 pixels) ma heli karaan macaamiisha laga bilaabo 2017, laakiin, fiiro gaar ah u leh sida la filayo inay heli doonaan, ugu yaraan tiro yar, ilaa 2020.
Khadadka hoose
Markaad soo iibsaneyso LCD TV maalmahan, waxaa laguu xaqiijin karaa in badankoodu aad u kulmaan ugu yaraan shuruudaha ugu hooseeya ee loo yaqaan 'HDTV'. Telefishinada qiyaasta 32-inch ama wax ka yar waxay yeelan karaan 720p ama 1080p taleefanka, telefishinnada 39-inch iyo weyn ayaa laga yaabaa inay ku ciyaaraan 1080p (HDTV) ama Ultra HD (4K) qaraashka soo bandhigida dhalashada.
Si kastaba ha ahaatee, waxaa laga yaabaa in kiisaska TV-yada qaarkood 24 inch iyo yaryar, halkaasoo laga yaabo inaad la kulanto 1024x768 bandhig bandhig, laakiin taasi waa marar dhif ah maalmahan.
Xasuuso in weli jiraan qaar ka mid ah TV-yada LCD-ka ee isticmaala kuwaas oo noqon kara SDTVs ama EDTVs - haddii aadan hubin waxa adiga kuugu yaryahay, ka fiirso calaamadaynta jadwalka, la tasho buugaaga gacanta, ama la xiriir taageero tiknoolajigaaga ee brand / Tusaale haddii ay suurtagal tahay.
