Yiyiphi iTV engcono ukuyithenga - i-4K okanye i-FullHD

Ngenxa yobuninzi bezinto ezinikezelwayo kwimarike ye-Smart TV, umbuzo wokukhetha izixhobo phakathi kwe-4K kunye ne-FullHD ibuzwa ngokuphindaphindiweyo. Nakwiminyaka emi-2-3 eyadlulayo, ukuqhutywa kwexabiso kwakukhulu kakhulu - 50-100%. Kodwa ngenxa yemfuno yeeTV ze-4K, ixabiso lehle kakhulu emva kokuba uninzi lweempawu zingene kwimarike. Kwaye umahluko kwixabiso awusabonakali kangako - 15-30%. Ngoko ke, kukho imibuzo engakumbi - yeyiphi iTV engcono ukuyithenga - i-4K okanye i-FullHD.

 

Asibandakanyi ukuthengisa - sijonga iimpawu zobugcisa

Ingongoma kukuba bonke abavelisi banomdla ekuthengiseni iimpahla ezibiza kakhulu. Kwaye izisombululo ezingabizi zijolise kwicandelo lohlahlo lwabiwo-mali. Awunakuvele uyivale, kuba kusoloko kukho umthengi onemali encinci. Ngoko uya kuthenga oko kungabizi, kodwa iTV enhle kangaka. Ngoko ke, kuwo onke amacandelo exabiso, sinikwa izisombululo ezininzi ngexesha elinye ukwenzela ukuba kube lula ukukhangela kuhlahlo lwabiwo-mali.

 

I-TV ye-4K okanye i-FullHD - eyona nto ingcono

 

Kungcono xa iTV ivelisa imibala yangempela. Kwaye akukhathaliseki nokuba sisiphi isisombululo enaso. Emva kwayo yonke loo nto, umdla womthengi kukufumana umgangatho womfanekiso endilisekileyo kwiscreen. Isisombululo yikhrayitheriya yesibini apha, exhomekeke kwizinto ezininzi ngaxeshanye:

 

• Ubungakanani bediagonal. 4K yi 4096x3072 amachaphaza nge-intshi nganye. Lo ngumgangatho. Kwaye iiTV zinesisombululo se-1 × 3840. I-FullHD yi-2160-1920 amachaphaza kwisikwere intshi nganye. Kwaye kwiiTV ezine-diagonal enkulu (ukusuka kwi-1080 ukuya kwi-intshi ye-55), ipixels kwi-matrix ye-FullHD iya kuba nkulu kune-matrix ye-80K. Oko kukuthi, akukho sizathu ekuthengeni i-TV ye-4K enesisombululo esingaphantsi kwee-intshi ze-4. Le yimali ephantsi kwe-drain.

• Ukusebenza kweprosesa yeTV. Bonke abavelisi, abakhuthaza iteknoloji yabo, bathule ukuba i-decoder eyakhelwe-ngaphakathi ayisoloko ilungele ukucubungula isignali ye-4K ngokuchanekileyo. Ukufumana umfanekiso okumgangatho ophezulu, isidlali-midiya (i-TV-BOX) siyafuneka. Kwaye kwi-FullHD, yonke into isebenza kakuhle kuyo nayiphi na iTV.
• Ikhono le-matrix ukusebenza ngee-shades zemibala. Kwiipaneli zexabiso eliphantsi, nakwisisombululo se-4K, umsebenzisi akayi kubona umgangatho ofunekayo. Kwaye kwimiboniso ebiza kakhulu, ifomathi ye-FullHD inokuvelisa imifanekiso enenyani ngakumbi.
• Umxholo. Ngokwendalo, iTV ye-4K idinga umthombo ofanelekileyo. Kwakhona, lo ngumdlali wemidiya okanye ividiyo yeYouTube. Uninzi lweefilimu kunye neevidiyo (kwaye oku kungaphezulu kwe-90%) kwi-HD okanye i-FullHD. Ukuba umsebenzisi akayi kuthenga iidiski zeBlue-Ray okanye ukukhuphela iimuvi kwi-4K, ngoko kunengqiqo ukuhlawula ngaphezulu kwesi senzo.

 

Yiyiphi iTV engcono ukuyithenga - i-4K okanye i-FullHD

 

Ngoko, sagqiba kwiindlela zokuthengisa. Ngoku lixesha lokuchukumisa itekhnoloji ebalulekileyo kwaye iluncedo kakhulu eya kubonelela umsebenzisi ngomgangatho wokuhanjiswa kwevidiyo.

 

• I-HDR 10 (i-High Dynamic Range) yimboniso yevidiyo enombala ophezulu wobunzulu. Oko kukuthi, uluhlu olwandisiweyo lwemibala, eyakhulelwa ngumenzi wefilimu. I-10 bits isinika i-1 yezigidigidi zee-shades. Kwaye i-8 bits isinika i-16 yezigidi ze-shades. Kubaluleke kakhulu, ukunyaniseka, ukuthenga iTV nge-HDR Kwicandelo lohlahlo lwabiwo-mali, phantsi kwe-HDR 10 yokumakisha, sinikezelwa nge-100% nge-8 + 2FRC. Ezi zi-2 FRCs luhlobo lwenkohliso, oluphuma kwi-16 yezigidi ze-shades zenza i-anti-aliasing phakathi kweepikseli.
• I-LED kunye ne-QLED (OLED). IiTV ezine-QLED matrix zibonisa umfanekiso oyinyaniso. Kodwa nazo zibiza 1.5-2 amaxesha ngaphezulu. Itekhnoloji yamachaphaza e-Quantum ikuvumela ukuba udlulise imithunzi ngendlela umbhali wevidiyo afuna ngayo. Kwaye i-LED yinkqubo yesignali yesoftware kunye nohlengahlengiso kumgangatho ofunekayo.

Kwinqanaba lokukhetha phakathi kwexabiso kunye nomgangatho, akukho nto inokufumaneka. Nokuba umgangatho, kodwa zibiza, okanye ixabiso elaneleyo, kodwa ngeendleko zokuzala kombala ophezulu. Kwaye kufuneka uzenzele isigqibo ngaphambi kokuba uye evenkileni.

 

Indlela yokukhetha iTV kwivenkile - isikhokelo sabaqalayo

 

Sigqibe ekubeni sithenge iTV enediagonal enkulu kwaye inexabiso eliphantsi - thatha nayiphi na enobungakanani ukuya kuthi ga kwi-intshi ye-60 FullHD. Kungcono ujonge uphawu. Ngokomzekelo, i-Samsung, i-LG okanye i-Philips iya kuhlala iminyaka eyi-10 kwaye iya kukuvuyisa ngomfanekiso onemibala. Nokuba iteknoloji. Iimveliso ezivela kubavelisi baseTshayina (i-KIVI kunye ne-Xiaomi ngokuqinisekileyo) zineminyaka eyi-3-5 ubudala kwaye i-matrix idinga ukutshintshwa.

Ukuba ufuna ukufumana umfanekiso okumgangatho ophezulu ngokwenene - khetha iiTV ukusuka kwii-intshi ezingama-55 ezinesisombululo se-4K kunye ne-HDR10. Ngokukhethekileyo nge-matrix ye-QLED. Kwaye ke, ziimpawu zehlabathi ezidumileyo zeSony, Samsung, LG. Iyabiza. Kodwa ukuguqulelwa kombala kuya kuba yinto emangalisayo kwaye ixesha elide.

Ukuba sithetha ngokuthenga 32-50 intshi TVs, ke kungcono ukuthatha FullHD. Sisisombululo nje sezoqoqosho, apho kungekho mahluko xa kuthelekiswa ne-4K. Kwaye musa ukukhohliswa kuthelekiso lukamabonwakude evenkileni. Emva koko, inkohliso isetyenziswa apho - imo yedemo. I-TV nganye inesimo se-DEMO esinjalo, xa ukukhanya kunye nokwahlukileyo kukhethwe ukuze umfanekiso ubonakale unamanzi ngakumbi. Ngendlela, kungcono ukuba ungathengi iiTV ezinjalo kwifestile. Akwaziwa ukuba basebenze ixesha elingakanani kumda wesakhono sabo.

I-LED kunye ne-QLED - yeyiphi onokuyithenga

 

Ukuba uhlahlo lwabiwo-mali luvumela, ngokuqinisekileyo i-QLED! Nokuba iibrendi zaseTshayina ezingabizi kakhulu, i-QLED ine-matrix epholileyo kunee-LED ezivela kwiinkokeli zentengiso ngokomgangatho. Oku kunokubonwa evenkileni, nangaphandle kwe-DEMO mode. Ngokomzekelo, ukuba uqala iifilimu ezinezicwangciso ezimnyama "I-Witcher" okanye "Imidlalo yeetrone". Kwi-sensor embi (ene-HDR kwi), kuya kubakho i-gray eqinile okanye amabala amnyama kwimvelaphi emnyama yehlathi, izakhiwo okanye izinto. Kwi-matrix ehloniphekileyo, iindawo ezifanayo) ziya kubonisa iinkcukacha ezincinci, ngaphandle kwehalos kunye nokudibanisa kunye nemvelaphi jikelele.

Ngokubanzi, unokwenza izibalo zemathematika. Apha umqeshwa karhulumente yenzelwe iminyaka 3-5. Kwaye iiTV zeenkokheli zemarike ziya kuhlala iminyaka eyi-10 okanye ngaphezulu. Ngokomyinge, i-TV ye-LED ye-55-intshi engabizi yi-$ 400, kwaye i-QLED yi-$ 800. Ukuba sithathela ingqalelo ubomi bokusebenza, iindleko ziyafana. Kuphela i-QLED enomgangatho womfanekiso ongcono kune-LED. Ke ngoko, ukuthenga iTV enamachaphaza e-quantum kunomdla ngakumbi kunezixhobo ezinematrix ephelelwe lixesha.
