Refresh Rate uye Sub-field Drive paPlasma TV
Plasma TV dzakagumiswa pakupera kwegore ra2014, asi dzaive nevakawanda vemafisi uye chaizvoizvo vashoma vavo vakabuda kunotenga mapepa ekupedzisira anoramba ari muzvitoro. Mamwe maTV aya achiri kushandiswa munyika yose, uye vatengi vakawanda vachiri kuda kufarira mufananidzo weplasma TV pamusoro pechirizvino reLCD TV.
Kunyange zvazvo isina kupa teknolojia yakakurumbira se 4K resolution uye HDR , maPlasma TV anopa maitiro akanaka kwazvo emhando uye kufamba kwekufamba kwekufambira. Nezvekufambisa kwekufambisa, shanduro yekutsvaga teknolojia inoita chikamu chikuru.
I-sub-field drive drive iyo inonzi yakasiyana neyeterevhizheni yeplasma . Inowanzotaurwa se 480Hz, 550Hz, 600Hz kana nhamba yakafanana. Kana iwe uchiri ne-plasma TV uye ukaramba kuparadzanisa nayo, kana kuwana kuwana yakagadziridzwa kana kushandisa plasma TV unofunga kuti inokosha kutenga, zvinorevei izvi?
Sub-munda Drive Rate vs. Screen Refresh Rate
Vashandi vakawanda vanotungamirirwa zvenhema kuti vatende kuti sub-field driving rate inofananidzwa nechikanda chekuvandudza tsanho , seyero rekuvandudza mitengo inowanzotaurwa kune LCD televisions. Kunyange zvakadaro, iyo-mashizha ekutsvaga purogiramu pane plasma TV chaizvoizvo inoreva chimwe chinhu chakasiyana.
Chirongwa chekuvandudza firiji ndechekuti kangani nguva purogiramu imwe neimwe inodzokororwa mukati menguva yakati, yakadai se1 / 60th yechipiri. Zvisinei, kunyange zvazvo maTV maTV ane rudzi rwekuberekwa kwe 60Hz rekuyera, vanoita chimwe chinhu kuwedzera kune izvi zvisinganzwisisiki zvinokurumidza kupindura. Mukutsigira chiyero chekugadzirisa zvinyorwa, vanoendesa zvakare kudzokorora magetsi kumapikisi kuti vachengetedze kuti vatarise kwenguva yekuti firimu rimwe rinoratidzwa pachikona. I-sub-field drive yakagadzirirwa kutumira izvi zvinokurumidza kubuda.
Plasma TV Pixels vs. LCD TV Pixels
Mapikisi anofanana nenzira dzakasiyana-siyana mumapurogiramu eplasma pane zvaanoita paLCD TV . Pixels muLCD TV inogona kuvharwa kana kuvharwa chero nguva ipi zvayo sezvo chiedza chinogara chiripo chinopfuudzwa kuburikidza neLCD chips. Zvisinei, LCD chips hazviiti kuti zvive chiedza chavo, dzinoda zvimwe zvekudzoka kana kuti nechepamusoro-famba chiedza kuitira kuti muve nemifananidzo iyo yaunogona kuona pahwindo.
Kune rumwe rutivi, pixel imwe neimwe muTlasma TV ndiyo inofungidzira. Izvi zvinorevei kuti mapikisesi ePlasma TV anoita chiedza chavo mukati memasero masero (hapanazve mamwe magetsi anowanikwa), asi anogona kungoita izvi kwenguva pfupi yakaenzana mumamisisecond. Kupinza kwemagetsi kunofanira kutumirwa pamhanho inokurumidza kumapikisa emafirimu epa plasma kuitira kuti ivo varambe vachipenya.
I-sub-field driving speculation inotaura chiyero chekuwanda kweiyi mapulisa inotumirwa kumapiksesi yese yechipiri kuti kuchengetedza chimiro chionekwe pahwindo. Kana plasma TV ine 60Hz yefesheni yekuvandudza purogiramu, iyo yakawanda zvikuru, uye kana sub-field drive inotumira 10 mapulisa kuti inakidze pixels mukati memakumi matanhatu eechipiri, iyo-field field drive rate inonzi 600Hz.
Mifananidzo inotaridzika zviri nani uye kufamba pakati pechimwe chimiro chaiyo chevhidhiyo chichatarisa chiri nani apo mamwe mapulisa anogona kutumirwa mukati me 60HZ yekuvandudza nguva yehuwandu. Izvi zvinokonzerwa nekuti chiedza che pixel hachikurumidze nokukurumidza panguva iyo firamu iri kuratidzwa, uye kana kuchinjwa kubva pahuturo kusvika pane.
The Bottom Line
Kunyange zvazvo LCD nePlasma TV dziri kunze zvakatarisa zvakafanana, pane zvakajeka mukati medu kusiyana kwekuti vanoonesa sei zvaunoona pahwindo. Chimwe chezvinhu zvakasiyana-siyana muPlasma TV ndekushandiswa kwe sub-field drive teknolojia yekusimudzira kufamba kwekuita.
Zvisinei, sezvakaitwa neLCD TV purogiramu yekuvandudza mitengo, iyi inogona kuva mutsara unonyengedza mutsara. Mushure mezvose, ingani mitoro inofanira kutumirwa pa1 / 60 yeimwe yechipiri kuti ione kuvandudzika kwehuwandu hwemufananidzo? Ko mutengi anganyatsoona mutsauko mufananidzo wehupenyu nekufambidzana pakati peTV yemalasma ane sub-field drive mazana e 480Hz, 600Hz kana 700Hz? Nzira yakanakisisa yekuwana nayo ndeyekuita maziso ako-pakuenzanisa kuti uone kuti chii chinotarisa kwauri.
Zvisinei, chimwe chinhu chinogona kutaurwa zvakananga; Hazvinei kuti chii chinonzi sub-field drive rate, Plasma TVs zvinowanzove nekufambisa kwakanaka kupfuura LCD TVs.
