Mawu amodzi omwe mungamve poyerekezera ma TV ndi ma "LED". Ogulitsa amakumana ndi chisokonezo chachikulu ponena za mitundu yosiyanasiyana ya ma TV omwe alipo lero ndi teknoloji mwa iwo. Mwa zina, ndichifukwa chakuti opanga kawirikawiri amapititsa patsogolo zoyenera za teknoloji inayake popanda kufotokozera momveka bwino ndi kuwapatsa mayina awo enieni.
Choyamba, muyenera kudziŵa kuti ma TV onse ali ndi mtundu wa LCD TV ; "Dzuwa" limangotanthauza mtundu wa magetsi omwe amagwiritsidwa ntchito kuwunikira ma pixels a LCD pa televizioni. Kulimbana ndi zovuta kwambiri ndi chakuti pali njira zambiri zowunikira ma pixelisi. Zipangizo zamakono ziwirizi ndizomwe zili m'mphepete mwadongosolo.
Dzuwa la Edge-Lit
Televizioni yomwe ili pamwamba pake ndi chitsanzo momwe ma LED omwe amaunikira ma pixelisi a LCD ali pambali pamphepete mwayikidwa. Ma LED ameneŵa amayang'ana kutsogolo kwawonekera kuti awunikire.
Izi zimathandiza kuti zitsanzozi zikhale zochepa komanso zopepuka. Amachita zimenezi ndi ndalama zochepa za khalidwe la chithunzi-makamaka m'madera omwe akuda. Malo akuda a chithunzithunzi, monga usiku womwe mumdima umasonyezedwera, sizili zakuda kwenikweni, koma zimawoneka ngati zowoneka ngati mdima wandiweyani chifukwa kuunikira kumabwera kuchokera m'mphepete ndi kuunikira mdima wambiri.
Mu mitundu ina ya maulendo operewera amtundu wosauka kwambiri, khalidwe lofananako la chithunzi lingakhale lovuta. Chifukwa chakuti ma LED ali pambali pamphepete mwa gululo, pamene mukuyandikira pakati pa chinsalu, kuchepa kwapamwamba chifukwa chiwerengero cha maonekedwe a uniform sichifikira mapilosi omwe ali kutali kwambiri. Apanso, izi zimawonekera kwambiri pazithunzi za mdima; wakuda pamphepete mwa chinsalu ndi wofiira kuposa wakuda (ndipo ngodya zingawoneke kukhala ndi mtundu wonyezimira wonyezimira wochokera kumakona).
Dongosolo Loyamba
LED yowonjezera imatanthawuza ma TV omwe amagwiritsa ntchito gulu lonse la ma LED kuti awalitse pixelesi. Zambiri mwazigawozi zimakhalanso ndi dera lakumidzi, zomwe zikutanthauza kuti ma LED akhoza kutayika m'madera osiyanasiyana a gululi pamene zigawo zina siziri. Izi zimathandiza kusintha mdima wakuda, womwe umawonekera pafupi ndi wakuda kuposa mdima wakuda.
Makanema ambirimbiri amakhala ochepa kwambiri komanso olemera kwambiri kuposa mafilimu amoto.
Edge-Lit ndi Loyamba Yoyenera
Kawirikawiri, chiwongoladzanja choyambirira chimaonedwa kuti ndi luso lamakono pazithunzi zazithunzi, koma maselo omwe ali ndi malire ali ndi mwayi umodzi waukulu: kuya. Ma TV opangidwa ndi magetsi akutha kukhala ochepa kwambiri kusiyana ndi omwe akuyatsa ndi mawonekedwe onse a LED kapena chiwonetsero cha mtundu wa fulorosenti (osakhala ndi LED). Pachifukwachi, zambiri zapamwamba kwambiri zomwe mumaziwona m'masitolo zidzakhala zozungulira.
Kodi ndi luso liti limene mukuyenera? Izi zimadalira zomwe mukufuna.
Ngati mukuyang'ana khalidwe labwino la zithunzi, mungathe kuzipeza muwonetsero wamakono omwe ali ndi dera lanu. Ngati mukudandaula kwambiri ndi maonekedwe a televizioni ndipo mukufuna kukhala ndi thupi lochepa kwambiri, loyang'ana m'mphepete ndilo ndondomeko yomwe idzakwaniritse zosowa zanu.
