Ireyithi yokuQala kwakhona kunye neDesk-Sub-Drive kwi-TV yePlasma
Iimvumi ze-Plasma zavalwa ngasekupheleni kuka-2014, kodwa zabaninzi abalandeli kwaye baninzi babo baphumelele ukuthenga iiplasmas ezidlulileyo ezisekhoyo kwiivenkile. Uninzi lwale maTV lusetyenziswa emhlabeni jikelele, kunye nabathengi abaninzi basasazela umgangatho womfanekiso weTV ye-plasma ngaphezu kwe-LCD ye-TV ekhoyo ngoku.
Nangona singanikeli iteknoloji ephambili njenge- 4K isisombululo kunye ne- HDR , iiTV zee-plasma zinika iqondo elimnyama elimangalisayo kunye nokulandela ukulandelela ukuhamba. Ngokubhekiselele ekusebenzeni kwesikhalazo, iteknoloji ye-drive yecandelo lenkqutyana inendima enkulu.
Isantya se-field field drive isicaciso esisodwa kumboniso we-plasma . Idla ngokuba ngu 480Hz, 550Hz, 600Hz okanye inombolo efanayo. Ukuba usenayo i-TV ye-plasma kwaye unqabe ukuyingxenye nayo, okanye ufumane i-TV ehlaziyiweyo okanye esebenzisa i-plasma ocinga ukuba ixabiso lokuthenga, kuthetha ukuthini oku?
I-Sub-field Drive Rate kunye neSreyithi yokuQala kwakhona
Abathengi abaninzi ba khokelwa ngokukhohlisa ukuba inqanaba le-drive ye-sub-field lifaniswa nereyiti yokuvuselela isikrini , njengokuba i-screen refresh rates echazwe kwii-TV zeLCD. Nangona kunjalo, isantya se-field field drive kwi-TV ye-plasma ibhekisela kwinto ehlukile.
Isilinganiselo sokuvuselela isikrini yingaphi izihlandlo eziliqela ziphindaphindiwe ngexesha elithile, njenge-1/60 yesibini. Nangona kunjalo, nangona i-TVma yeTlasma ine-60Hz yesiqhelo sokuvuselela isikrini, benza into ngokubhekisele kule mpendulo ehamba phambili. Ukuxhaswa kwezinga lokuvuselela isikrini, baphinde bathumele ukuqhuma kombane ngokuphindaphindiweyo kwiipekseli ukuze bahlale belilele ixesha elithile apho ifreyimu nganye iboniswa kwisikrini. I-sub-field drive yenzelwe ukuthumela ezi ziphapho ezikhawulezayo.
Iiplastiki zePlasma ze-TV kunye neePixel ze-LCD TV
Iipekseli ziziphatha ngokuhlukileyo kwiTV ye-plasma kunokuba zenze kwii- TV ze-LCD . Iipixels kwi-TV yeLCD inokuvulwa okanye ikhutshwe naliphi na ixesha njengoko umthombo wokukhanya oqhubekayo udluliselwa kwii-chips ze-LCD. Nangona kunjalo, ii-LCD chips aziyikuvelisa ukukhanya kwazo, zifuna umthombo wongeziweyo okanye umbane wokukhanya ukuze uvelise imifanekiso ongayibona kwesikrini.
Ngakolunye uhlangothi, i-pixel nganye kwiTV ye-plasma iyisistim. Oko kuthetha ukuba iipekseli zeplasmesi ze-plasma zivelisa ukukhanya kwazo ngaphakathi kweso sakhiwo (akukho mthombo wongeza umthombo ofunekayo), kodwa unokukwenza kuphela ixesha elifutshane kakhulu elilinganiselwa kwiimillisecond. Amagalelo kagesi kufuneka athunyelwe ngezinga elikhawulezayo kwiipekseli ze-TV ze-plasma ukuze zihlale zilele.
I-sub-field spection specification ithi izinga lingaphi lala manzi athunyelwa kwiipekseli ngasinye sesibini ukugcina isakhelo sibonakala kwisikrini. Ukuba i-TV ye-plasma inomlinganiselo wokuvuselela isikrini se-60Hz, eyona nto ixhaphakileyo, kwaye ukuba i-sub-field drive iyathumela iipulsi ezili-10 ukuba zijabulise iipekseli zingama-60 yesibini, isantya sokuqhuba isantya sichazwa njenge-600Hz.
Izithombe ziza kubonakala zingcono kwaye ukunyakaza phakathi kwesakhelo ngasinye sevidiyo siza kubonakala siphumelele xa ezinye iintlobo zingathunyelwa kwisithuba se-60HZ sexesha lokuvuselela. Oku kubangelwa kukuba i-pixel ukukhanya ayikubola ngokukhawuleza ngelixesha apho isakhelo sibonakaliswa, okanye xa ushintsho ukusuka kwisakhelo kwisakhelo.
Ngaphantsi
Nangona i-LCD kunye ne-Plasma TV zikhangeleka ngaphandle, kukho ukungafani kwangaphakathi kwindlela ababonisa ngayo oko ubona kwiskrini. Enye yeemeko ezahlukileyo kwii-TV zasePlasma kukusetyenziswa kwethempyutheni yecandelo le-drive ukuphucula impendulo.
Nangona kunjalo, njengokuba i-LCD TV ihlaziya ukuhlaziya ixabiso, le nto ingaba umdlalo weenombolo ezikhohlisayo. Emva koko, zingaphi iipulisi kufuneka zithunyelwe nge-1/60 yesibini ukuze zibone ukuphucula umgangatho womfanekiso ohambayo? Ingaba umthengi angayibona ngokwenene umgangatho womfanekiso kunye nenkqubela phakathi kwamaTV e-plasma anamazinga angama-480 eHz, 600Hz okanye 700Hz? Indlela efanelekileyo yokufumana ukuba ukwenene ngokwenene amehlo akho-xa uqhathanisa ukubona oko kubonakala kukugqwesileyo kuwe.
Nangona kunjalo, into enye ingachazwa ngokuchanekileyo; Kungakhathaliseki ukuba yintoni umlinganiselo wesantya we-drive, ii-Plasma TV zineempendulo ezingcono kunezo ziLCD TV.
