Iyiphi i-TV engcono ukuyithenga - 4K noma i-FullHD

Ngenxa yobuningi bokunikezwayo emakethe ye-Smart TV, umbuzo wokukhetha imishini phakathi kwe-4K ne-FullHD ubuzwa kaningi. Ngisho neminyaka engu-2-3 edlule, ukukhuphuka kwentengo kwakukhulu kakhulu - 50-100%. Kodwa ngenxa yesidingo sama-TV we-4K, izindleko zehle kakhulu ngemuva kokuthi inqwaba yemikhiqizo ingene emakethe. Futhi umehluko wentengo awusabonakali kangako - 15-30%. Ngakho-ke, kunemibuzo eyengeziwe - iyiphi i-TV engcono ukuyithenga - 4K noma i-FullHD.

 

Asikufaki ukumaketha - sibheka izici zobuchwepheshe

Iphuzu liwukuthi bonke abakhiqizi banesithakazelo ekuthengiseni izimpahla ezibiza kakhulu. Futhi izixazululo ezingabizi ziqondiswe engxenyeni yesabelomali. Awukwazi ukuvele uyivale, ngoba kuhlale kukhona umthengi onemali elinganiselwe. Ngakho-ke uzothenga lokho okungabizi, kodwa i-TV enhle kangaka. Ngakho-ke, kuzo zonke izingxenye zentengo, sinikezwa izixazululo ezimbalwa ngesikhathi esisodwa ukuze senze ukusesha kubhajethi.

 

I-4K TV noma i-FullHD - okungcono

 

Kungcono uma i-TV ikhiqiza imibala yangempela. Futhi akunandaba ukuthi inasiphi isixazululo. Phela, intshisekelo yomthengi ukuthola ikhwalithi yesithombe ehloniphekile esikrinini. Ukulungiswa kuwumbandela wesibili lapha, oncike ezintweni ezimbalwa ngesikhathi esisodwa:

 

• Usayizi we-diagonal. I-4K ingamachashazi angu-4096x3072 iyintshi yesikwele. Yilokhu okujwayelekile. Futhi ama-TV anesinqumo esingu-1 × 3840. I-FullHD ingamachashazi angu-2160-1920 iyintshi yesikwele. Futhi kuma-TV ane-diagonal enkulu (kusuka ku-1080 kuya ku-55 amayintshi), amaphikseli ku-matrix ye-FullHD azoba makhulu kunaku-matrix ye-80K. Okusho ukuthi, asikho isidingo sokuthenga i-TV ye-4K enesinqumo esingaphansi kwama-intshi angu-4. Le yimali ephuma emfuleni.

• Ukusebenza kweprosesa ye-TV. Bonke abakhiqizi, abaphromotha ubuchwepheshe babo, bathula ukuthi idikhoda eyakhelwe ngaphakathi ayihlali ilungele ukucubungula isignali ye-4K ngendlela efanele. Ukuthola isithombe sekhwalithi ephezulu, isidlali semidiya (TV-BOX) siyadingeka. Futhi ku-FullHD, yonke into isebenza kahle kunoma iyiphi i-TV.
• Ikhono le-matrix ukusebenza ngemibala enemibala. Kumaphaneli ashibhile, ngisho nasekulungisweni kwe-4K, umsebenzisi ngeke abone ikhwalithi oyifunayo. Futhi kuzibonisi ezibizayo, ifomethi ye-FullHD ingakhiqiza izithombe ezingokoqobo.
• Okuqukethwe. Ngokwemvelo, i-4K TV idinga umthombo ofanele. Futhi, lesi isidlali semidiya noma ividiyo ye-YouTube. Iningi lamafilimu namavidiyo (futhi lokhu kungaphezu kuka-90%) aku-HD noma i-FullHD. Uma umsebenzisi engeke athenge ama-Blue-Ray discs noma alande amamuvi abe yi-4K, khona-ke kunengqondo ukukhokhela ngaphezulu kwalokhu kusebenza.

 

Iyiphi i-TV engcono ukuyithenga - 4K noma i-FullHD

 

Ngakho-ke, sinqume ngamaqhinga wokumaketha. Manje yisikhathi sokuthinta ubuchwepheshe obubalulekile nobuwusizo kakhulu obuzohlinzeka umsebenzisi ngekhwalithi yokudluliswa kwevidiyo.

 

• I-HDR 10 (High Dynamic Range) isibonisi sevidiyo esinombala ojule kakhulu. Okusho ukuthi, ububanzi obuningi bemibala, obuqanjwe ngumenzi wefilimu. I-10 bits isinika ama-shades ayizigidi eziyizinkulungwane ezingu-1. Futhi amabhithi ayi-8 asinika imithunzi eyizigidi eziyi-16. Kubaluleke kakhulu, ngokungokoqobo, ukuthenga i-TV ene-HDR Engxenyeni yesabelomali, ngaphansi kokumaka i-HDR 10, sinikezwa i-100% nge-8 + 2FRC. Lawa ma-FRC ama-2 awuhlobo lwenkohliso, okuthi ezigidini eziyi-16 zamathunzi enza i-anti-aliasing phakathi kwamaphikseli.
• I-LED ne-QLED (OLED). Ama-TV ane-QLED matrix abonisa isithombe esingokoqobo. Kodwa futhi zibiza izikhathi ezingu-1.5-2 ngaphezulu. Ubuchwepheshe bechashazi be-Quantum bukuvumela ukuthi udlulise ama-shades ngendlela umbhali wevidiyo ayehlosile. Futhi i-LED iwukucubungula isignali yesofthiwe ngokulungiswa kwekhwalithi oyifunayo.

Esigabeni sokukhetha phakathi kwentengo nekhwalithi, akukho ukuyekethisa okungatholakala. Kungakhathaliseki ukuthi ikhwalithi, kodwa iyabiza, noma intengo eyanele, kodwa ngezindleko zokukhiqiza umbala ophezulu. Futhi udinga ukuzinqumela ngaphambi kokuya esitolo.

 

Indlela yokukhetha i-TV esitolo - umhlahlandlela wabaqalayo

 

Sinqume ukuthenga i-TV ene-diagonal enkulu futhi eshibhile - thatha noma iyiphi enosayizi ongafika kumayintshi angu-60 i-FullHD. Kungcono ubheke umkhiqizo. Isibonelo, i-Samsung, i-LG noma i-Philips izohlala iminyaka engu-10 futhi izokujabulisa ngesithombe esinemibala. Kungakhathaliseki ubuchwepheshe. Imikhiqizo evela kubakhiqizi baseShayina (i-KIVI ne-Xiaomi ngokuqinisekile) ineminyaka engu-3-5 ubudala futhi i-matrix idinga ukushintshwa.

Uma ufuna ukuthola isithombe sekhwalithi ephezulu ngempela - khetha ama-TV kusukela kumayintshi angu-55 anokulungiswa kwe-4K ne-HDR10. Okungcono kakhulu nge-matrix ye-QLED. Futhi-ke, izinhlobo zomhlaba ezidumile kuphela ze-Sony, Samsung, LG. Kuyabiza. Kodwa ukukhishwa kombala kuzoba okumangalisayo futhi isikhathi eside.

Uma sikhuluma ngokuthenga ama-TV angama-intshi angu-32-50, kungcono ukuthatha i-FullHD. Kuyisixazululo nje esinomnotho, lapho okungekho mehluko khona uma kuqhathaniswa ne-4K. Futhi ungakhohliswa ukuqhathaniswa kwe-TV yasesitolo. Phela, inkohliso isetshenziswa lapho - imodi yedemo. I-TV ngayinye inemodi yeDEMO enjalo, lapho ukukhanya nokugqama kukhethwa ukuze isithombe sibukeke sinamanzi amaningi. Ngendlela, kungcono ukuthi ungathengi ama-TV anjalo efasiteleni. Akwaziwa ukuthi basebenze isikhathi esingakanani emkhawulweni wamakhono abo.

I-LED ne-QLED - iyiphi ongayithenga

 

Uma isabelomali sivuma, nakanjani i-QLED! Ngisho nemikhiqizo yamaShayina engabizi kakhulu, i-QLED ine-matrix epholile kunama-LED avela kubaholi bemakethe ngokwekhwalithi. Lokhu kungabonakala esitolo, ngisho nangaphandle kwemodi yeDEMO. Isibonelo, uma uqala amafilimu anezinhlelo ezimnyama "The Witcher" noma "Game of Thrones". Kunzwa embi (evuliwe nge-HDR), kuzoba khona amachashaza aqinile ampunga noma amnyama kungemuva elimnyama lehlathi, izakhiwo noma izinto. Ku-matrix ehloniphekile, izindawo ezifanayo) zizobonisa imininingwane emincane, ngaphandle kwama-halos futhi ihlanganiswe nengemuva elijwayelekile.

Ngokuvamile, ungenza izibalo zezibalo. Lapha isisebenzi sikahulumeni senzelwe iminyaka engu-3-5. Futhi ama-TV abaholi bemakethe azohlala iminyaka eyi-10 noma ngaphezulu. Ngokwesilinganiso, i-TV ye-LED engama-intshi angu-55 eshibhile ingu-$400, kanti i-QLED ingu-$800. Uma sicabangela impilo yokusebenza, izindleko ziyefana. I-QLED kuphela enekhwalithi yesithombe engcono kune-LED. Ngakho-ke, ukuthenga i-TV enamachashazi e-quantum kuthakazelisa kakhulu kunemishini ene-matrix ephelelwe yisikhathi.
