Ndi TV iti yomwe ili yabwino kugula - 4K kapena FullHD

Chifukwa cha kuchuluka kwa zopereka pamsika wa Smart TV, funso losankha zida pakati pa 4K ndi FullHD likufunsidwa pafupipafupi. Ngakhale zaka 2-3 zapitazo, kuthamanga kwamtengo kunali kwakukulu - 50-100%. Koma chifukwa cha kufunikira kwa ma TV a 4K, mtengo watsika kwambiri malonda ambiri atalowa pamsika. Ndipo kusiyana kwa mtengo sikulinso kuwonekera - 15-30%. Chifukwa chake, pali mafunso ambiri - ndi TV iti yabwino kugula - 4K kapena FullHD.

 

Sitikupatula malonda - timayang'ana zaukadaulo

Mfundo ndi yakuti opanga onse ali ndi chidwi chogulitsa zinthu zodula kwambiri. Ndipo mayankho otsika mtengo amayang'ana gawo la bajeti. Simungathe kungotseka, chifukwa nthawi zonse pamakhala wogula yemwe ali ndi ndalama zochepa. Kotero adzagula TV yotsika mtengo, koma yokongola ngati imeneyi. Chifukwa chake, m'magulu onse amitengo, timapatsidwa mayankho angapo nthawi imodzi kuti tithandizire kusaka pa bajeti.

 

4K TV kapena FullHD - zomwe zili bwino

 

Ndi bwino pamene TV imabala mitundu yeniyeni. Ndipo zilibe kanthu kuti ali ndi chigamulo chotani. Kupatula apo, chidwi cha wogula ndikupeza chithunzithunzi chabwino pazenera. Kusamvana ndi njira yachiwiri apa, yomwe imadalira zinthu zingapo nthawi imodzi:

 

• Kukula kwa diagonal. 4K ndi 4096x3072 madontho pa mainchesi lalikulu. Uwu ndiye muyezo. Ndipo ma TV ali ndi lingaliro la 1 × 3840. FullHD ndi 2160-1920 madontho pa mainchesi lalikulu. Ndipo kwa ma TV okhala ndi diagonal yayikulu (kuyambira 1080 mpaka 55 mainchesi), ma pixel omwe ali pa FullHD matrix adzakhala akulu kuposa matrix a 80K. Ndiye kuti, palibe chifukwa chogula TV ya 4K yokhala ndi malingaliro osakwana mainchesi 4. Izi ndi zotsika mtengo.

• Ntchito ya purosesa ya TV. Opanga onse, akulimbikitsa ukadaulo wawo, amakhala chete kuti decoder yomangidwa sikhala yokonzeka nthawi zonse kukonza chizindikiro cha 4K molondola. Kuti mupeze chithunzi chapamwamba, TV player (TV-BOX) imafunika. Ndipo mu FullHD, chilichonse chimagwira ntchito bwino pa TV iliyonse.
• Kutha kwa matrix kugwira ntchito ndi mithunzi yamitundu. Pa mapanelo otsika mtengo, ngakhale muzosankha za 4K, wogwiritsa ntchitoyo sadzawona mtundu womwe akufuna. Ndipo pazowonetsa zodula, mawonekedwe a FullHD amatha kupanga zithunzi zenizeni.
• Zamkatimu. Mwachilengedwe, TV ya 4K imafunikira gwero loyenera. Apanso, ichi ndi media player kapena YouTube kanema. Makanema ndi makanema ambiri (ndipo izi ndizoposa 90%) ali mu HD kapena FullHD. Ngati wosuta sinditi kugula Blue-Ray zimbale kapena kukopera mafilimu kwa 4K, ndiye n'zomveka kuti overpay ntchito imeneyi.

 

Ndi TV iti yomwe ili yabwino kugula - 4K kapena FullHD

 

Kotero, tinaganiza za njira zamalonda. Ino ndi nthawi yokhudza matekinoloje ofunikira komanso othandiza kwambiri omwe angapatse wogwiritsa ntchito mawonekedwe amavidiyo.

 

• HDR 10 (High Dynamic Range) ndi kanema wowonetsa kuzama kwamitundu. Ndiko kunena kuti, mitundu yowonjezereka yamitundu, yomwe idapangidwa ndi wopanga filimuyo. Ma bits 10 amatipatsa mithunzi 1 biliyoni. Ndipo ma bits 8 amatipatsa mithunzi 16 miliyoni. Ndikofunikira kwambiri, chifukwa chenichenicho, kugula TV ndi HDR Mu gawo la bajeti, pansi pa chizindikiro cha HDR 10, timapatsidwa 100% ndi 8 + 2FRC. Ma 2 FRCs awa ndi achinyengo, omwe mwa mithunzi 16 miliyoni amachita anti-aliasing pakati pa ma pixel.
• LED ndi QLED (OLED). Ma TV okhala ndi QLED matrix amawonetsa chithunzi chowoneka bwino. Koma amawononganso 1.5-2 nthawi zambiri. Tekinoloje ya madontho a Quantum imakulolani kusamutsa mithunzi momwe wolemba vidiyoyo amafunira. Ndipo LED ndi pulogalamu yamapulogalamu yosinthira ndikusintha kumtundu womwe mukufuna.

Pa siteji yosankha pakati pa mtengo ndi khalidwe, palibe kunyengerera komwe kungapezeke. Kaya mtundu, koma wokwera mtengo, kapena mtengo wokwanira, koma pakuwononga mtundu wapamwamba kwambiri. Ndipo muyenera kusankha nokha musanapite ku sitolo.

 

Momwe mungasankhire TV m'sitolo - kalozera woyamba

 

Tidaganiza zogula TV yokhala ndi diagonal yayikulu komanso yotsika mtengo - tengani iliyonse yokhala ndi mainchesi 60 FullHD. Bwino kuyang'ana chizindikiro. Mwachitsanzo, Samsung, LG kapena Philips ikhala zaka 10 ndikukusangalatsani ndi chithunzi chokongola. Mosasamala zaukadaulo. Zogulitsa kuchokera kwa opanga aku China (KIVI ndi Xiaomi motsimikizika) ali ndi zaka 3-5 ndipo matrix ayenera kusinthidwa.

Ngati mukufuna kupeza chithunzi chapamwamba kwambiri - sankhani ma TV kuchokera mainchesi 55 okhala ndi 4K resolution ndi HDR10. Makamaka ndi matrix a QLED. Ndipo, ndithudi, ndi otchuka okha padziko lonse zopangidwa Sony, Samsung, LG. Zokwera mtengo. Koma kumasulira kwamtundu kudzakhala kodabwitsa komanso kwa nthawi yayitali.

Ngati tikukamba za kugula ma TV a 32-50 inchi, ndiye kuti ndi bwino kutenga FullHD. Ndi njira yokhayo yachuma, yomwe palibe kusiyana kulikonse poyerekeza ndi 4K. Ndipo musapusitsidwe ndi kufananitsa TV m'sitolo. Kupatula apo, chinyengo chimagwiritsidwa ntchito pamenepo - mawonekedwe owonera. TV iliyonse ili ndi mawonekedwe a DEMO, pamene kuwala ndi kusiyana kumasankhidwa kuti chithunzicho chiwoneke chowutsa mudyo. Mwa njira, ndi bwino kuti musagule ma TV oterowo pawindo. Sizikudziwika kuti adagwira ntchito nthawi yayitali bwanji potengera kuthekera kwawo.

LED ndi QLED - yomwe mungagule

 

Ngati bajeti ilola, ndithudi QLED! Ngakhale mitundu yotsika mtengo yaku China, QLED ili ndi matrix ozizirirapo kuposa ma LED ochokera kwa atsogoleri amsika malinga ndi mtundu. Izi zitha kuwoneka m'sitolo, ngakhale popanda DEMO mode. Mwachitsanzo, ngati muyamba mafilimu ndi ziwembu zakuda "Witcher" kapena "Game of Thrones". Pa sensa yoyipa (yokhala ndi HDR), padzakhala mawanga otuwa kapena akuda pamalo amdima ankhalango, nyumba kapena zinthu. Pa matrix abwino, madera omwewo) adzawonetsa zing'onozing'ono, popanda ma halos ndikuphatikizana ndi maziko onse.

Mwambiri, mutha kuwerengera masamu. Apa wantchito boma lakonzedwa kwa zaka 3-5. Ndipo ma TV a atsogoleri amsika azikhala zaka 10 kapena kupitilira apo. Pafupifupi, TV yotsika mtengo ya 55-inch LED ndi $ 400, ndipo QLED ndi $ 800. Ngati tiganizira za moyo wogwira ntchito, ndalamazo zimakhala zofanana. QLED yokhayo ili ndi chithunzi chabwinoko kuposa LED. Chifukwa chake, kugula TV yokhala ndi madontho a quantum ndikosangalatsa kwambiri kuposa zida zomwe zili ndi matrix osatha.
