MukagulaTV, nthawi zambiri timasokonezeka ndi mawu monga “4K resolution” ndi “high refresh rate,” koma anthu ochepa amazindikira kuti “ngwazi yosaimbidwa” yomwe imatsimikiza khalidwe la chithunzi kwenikweni ndi “yankho la kuwala” Mwachidule, yankho la kuwala ndi njira zomwe TV imagwiritsa ntchito “kusamalira kuwala”: momwe mungapangire kuwala kupanga zithunzi molondola, momwe mungapangire mitundu kukhala yeniyeni, momwe mungapewere kuwala kuchokera ku kuwala… Zili ngati “maso” a TV, zomwe zimakhudza mwachindunji zomwe timakumana nazo pakuonera masewero ndi makanema.
I. Choyamba, fotokozani: Kodi yankho la kuwala limalamulira chiyani kwenikweni?
Pafupifupi malingaliro athu onse omveka bwino tikamaonera TV amagwirizana ndi yankho la kuwala, lomwe makamaka limalamulira zinthu zitatu:
1. Kuwala koonekera bwino ndi mdima: Palibe zithunzi zakuda zotuwa kapena zithunzi zowala kwambiri. Mwachitsanzo, mukamayang'ana zithunzi zakuthambo muNyenyezi zapakati, mungathe kusiyanitsa tsatanetsatane wamdima wozungulira dzenje lakuda popanda kuchititsidwa khungu ndi kuwala kwamphamvu kwa nyenyezi;
2. Mitundu yeniyeni: Yofiira yeniyeni, buluu yeniyeni, yopanda "mtundu" kapena "yofooka." Mwachitsanzo, poonera filimu yokhudza nkhalango zamvula za m'madera otentha, masamba obiriwira a emerald ndi maluwa ofiira owala amatha kubwezeretsedwa kuti azioneka ngati zenizeni;
3. Kuletsa mwamphamvu kusokoneza: Osaopa kuwala kozungulira. Mwachitsanzo, makatani akatsegulidwa masana kapena magetsi akayaka usiku, chithunzicho chimakhala chowonekera bwino ndipo sichidzasokonezedwa ndi kuwala.
II. Mitundu yodziwika bwino ya mayankho a kuwala: Maukadaulo osiyanasiyana, zokumana nazo zosiyana kwambiri
Pakadali pano, njira zazikulu zowunikira pa TV zimagawidwa m'mitundu itatu, iliyonse ili ndi zochitika zoyenera komanso zosowa zogwiritsira ntchito:
1. Yankho la Mini LED Optical: "Mfumu yatsatanetsatane" ya kulamulira kolondola kwa kuwala
Iyi ndi "njira yodziwika bwino" ya ma TV a LCD apakatikati mpaka apamwamba, ndi ubwino waukulu wa "kuwongolera kuwala kolondola." Mfundo yake ndi yosavuta: mikanda ing'onoing'ono ya LED yambirimbiri imayikidwa mu gawo la TV la backlight, ndipo mikanda iyi imagawidwa m'magawo ambiri ang'onoang'ono - m'malo owoneka bwino, mikanda m'malo ofananira imawala; m'malo owoneka amdima, mikanda m'malo ofananira imawala pang'ono kapena imazima kwathunthu.
Mwachitsanzo, poonera filimu yowopsa ya "mdima wozungulira" pa "mdima wozungulira" pa "mdima wozungulira" TV zachikhalidwe zimakhala ndi "ma halo" m'mphepete mwa "mbali" ya ...
Mtundu wapamwamba kwambiri wa “RGB-Mini LED” umalola mikanda yofiira, yobiriwira, ndi yabuluu kutulutsa kuwala payokha, kuchotsa kufunikira kwa “kusintha mitundu yosiyanasiyana” monga njira zachikhalidwe. Izi zimapangitsa kuti mitundu ikhale yolondola kwambiri, zomwe zimapangitsa kuti zinthu ziwoneke bwino kwambiri mukamaonera makanema ojambula kapena mafilimu okhala ndi mitundu yosiyanasiyana.
2. Yankho la Laser TV Optical: "Chosungira malo" kwa okonda ma screen akuluakulu
Ma TV a laser ndi osiyana kwambiri ndi ma TV achikhalidwe: m'malo mwa "ma screen odziwunikira okha," amagwiritsa ntchito magwero a kuwala kwa laser kuti awonetse zithunzi pa ma screen apadera. Ubwino wake waukulu ndi "kusunga malo, kuthekera kwa ma screen akuluakulu," komanso kupewa kuwonongeka kwa maso chifukwa cha kuwala mwachindunji.
Ma TV akale a laser anali ndi vuto: ankatha kuzindikira kuwala kozungulira, zomwe zinkafuna kuti makatani azijambulidwa masana kuti azioneka bwino. Tsopano, mbadwo watsopano wa njira zowunikira za laser, kudzera mu "kapangidwe ka njira yowunikira" komanso "zinthu zowonekera," zimatha kutseka kuwala kozungulira kopitilira 80% - ngakhale magetsi atayatsidwa ndipo makatani atatsegulidwa masana, chithunzicho chimakhalabe chowonekera bwino komanso chowonekera bwino, sichifunikanso kuyika kuwala. Kuphatikiza apo, chili ndi malo ochepa kwambiri, chomwe chimatha kuwonetsa chophimba chachikulu cha mainchesi 100 chomwe chili pamtunda wa masentimita 10 kuchokera pakhoma, kulola zipinda zazing'ono zochezera kusangalala ndi kanema.
3. Yankho la LED Yokhazikika: Njira yotsika mtengo
Iyi ndi njira yodziwika bwino yogwiritsira ntchito ma TV apakatikati. Mfundo yake ndi "kuwala kwa magetsi onse," kenako kugwiritsa ntchito zosefera ndi zofalitsa kuti kuwala kufalikire mofanana. Ubwino wake ndi wotsika mtengo komanso wotsika mtengo, zomwe zimakwaniritsa zosowa za tsiku ndi tsiku monga kuonera nkhani ndi masewero nthawi zonse; vuto lake ndi kulondola kosayenera kwa kuwala, komwe kumawoneka ngati zithunzi zakuda ndi ma halos, komwe kumawoneka kotsika poyerekeza ndi njira ziwiri zapitazi.
III. Kodi mungasankhe bwanji njira yowunikira pogula TV? Kumbukirani mfundo zitatu zosavuta
Palibe chifukwa chokumbukira magawo ovuta — mvetsani mfundo zitatu izi kuti mupewe mavuto:
1. Chongani "chiwerengero cha madera ofooka" (a ma TV ang'onoang'ono a LED): Pa kukula komweko, madera ambiri amatanthauza kuwongolera bwino kuwala komanso tsatanetsatane wamdima womveka bwino. Mwachitsanzo, TV ya mainchesi 85 yokhala ndi madera opitilira 500 imatha kukwaniritsa zosowa za tsiku ndi tsiku zowonera, pomwe madera opitilira 1000 ndi oyenera kwa iwo omwe akufuna chithunzi chabwino kwambiri;
2. Chongani "mphamvu yotsutsana ndi kuwala" (ya ma TV a laser): Mukagula, funsani za "kusiyana kwa kuwala kozungulira," kapena yesani mwachindunji m'sitolo magetsi akayaka. Yodalirika idzakuthandizani kuwona bwino chithunzi popanda kuwala koonekeratu;
3. Chongani "zowonera zenizeni" (zachilengedwe): Kaya zinthuzo ndi zabwino bwanji, muyenera kuzionera nthawi zonse — chongani ngati zinthu zakuda zili ndi imvi, ngati mitundu ndi yachilengedwe, komanso ngati zinthu zowala zili zowala kwambiri. Chomwe chikugwirizana ndi zomwe mumachita ndi chabwino kwambiri.
IV. Chidule chomaliza: Mayankho a maso si "chinsinsi," koma zokumana nazo zothandiza
Ndipotu, njira zowunikira siziyenera kukhala zovuta kwambiri. Cholinga chawo chachikulu ndi "kupangitsa kuwala kumvetsetsa maso athu bwino": kulola malo owala kuwala, malo amdima kukhala ochepa, kupangitsa mitundu kukhala ngati yeniyeni, komanso kutilola kuonera zithunzi momasuka kulikonse.
Ngati mukufuna chithunzi chabwino kwambiri ndipo nthawi zambiri mumaonera makanema, sankhani njira ya RGB-Mini LED; ngati mukufuna sikirini yayikulu ndipo muli ndi chipinda chochezera chaching'ono, sankhani laser ya m'badwo watsopano.Yankho la pa TV; ngati mumaonera masewero tsiku lililonse ndipo muli ndi bajeti yochepa, yankho la LED lokhazikika ndilokwanira. Kumvetsetsa mayankho a kuwala kudzakutetezani kuti musasocheretsedwe ndi "machenjerero a parameter" a amalonda mukamagula TV!
