Isiphi Isisombululo Siphezulu Esikhenketho seThebhulethi?
Njengoko umboniso we-TV we-4K uhlawulela phezulu, siqala ukuva ngaphezulu nangaphezulu malunga ne-4k ehlasela umhlaba weepilisi. Kodwa ngelixa iinkampani ezinjenge-Samsung ziye zajikeleza nge-4K buzzword, ezi zibhebhile ziye zawa mfutshane kwinqanaba lesisombululo sesiskrini. Kwaye kunye ne-Apple ngoku ngokubonisa iziboniso zabo zeeNyaniso, sinomnye u-buzzword ukulwa nalo. Ngaba ngokwenene sifuna amaphilisi amane? Yaye i-4K ibeka njani kwi-Retina Display? Kuthiwani ngeTone leNyaniso?
Yintoni iReitina Display?
Inxalenye edidekileyo malunga ne-Retina Display kukuba iza nezigqibo ezininzi zeeskrini. Isiboniso se-4K ngokuqhelekileyo sisisombululo esingu-3,840x2,160 kungakhathaliseki ubungakanani bobuboniso, kodwa isisombululo se-Retina Display sitshintshintsha ngokusekelwe kubukhulu bomboniso.
Njengoko kuthiwa yi-Apple, i-Retina Display iyisikrini esinobuninzi beepixel ephakamileyo ngokwaneleyo ukuba iipikseli zomntu ngamnye azikwazi ukuqondwa ngamehlo omntu xa ifowuni ibanjwe kumgama oqhelekileyo wokubukela. "Umgama oqhelekileyo wokubukela" luyingxenye ebalulekileyo yalolu lingano kuba ulusondeza idivayisi, encinci iipekseli ngamnye ziya kufuneka zibe phambi kokuba zingabonakali. I-Apple ibona umgama oqhelekileyo wokubukela we-smartphone ukuba ube malunga nee-intshi eziyi-10-12 kwaye umgama oqhelekileyo wokubukela kwithebhulethi ibe ngama-intshi ama-15.
Ukwahlula kwe-Retina Ukubaluleka kubalulekile kuba nayiphi isisombululo esiphezulu sekrini asiboneleli nzuzo nayiphi na inzuzo. Xa iliso lomntu lingenakukwazi ukuhlukanisa iipekseli ngabanye, umboniso ucocekile njengoko unako. Enyanisweni, izisombululo eziphezulu zesikrini zidinga amandla angaphezulu, ekhangela amandla amaninzi ukusuka kwibhetri. Ngokugqithiseleyo "I-Retina Display" ingakwazi ukuphazamisa kwisixhobo.
Ngaba i-4k nje i-Scam yi-Industry Industry?
Kukho umehluko obalulekileyo phakathi kwethebhulethi kunye nomabonwakude. Umabonwakude usetyenziswa ngokuyinhloko ukubukela ividiyo. Kwaye ukuba siphume kakhulu kwividiyo esibukeleyo, isisombululo sethu sethelevishini kufuneka sifane nesisombululo sevidiyo. Ngoko nangona iithelevishini zifika ngobukhulu obuhlukeneyo, icandelo ludinga isisombululo esifanelekileyo sekrini ukufanisa ividiyo eveliswe ngesisombululo somabonwakude. Akuyi kwenza nantoni na ukuba ibe nesisombululo esiphezulu kumabonwakude amakhulu xa umfanekiso kwiskrini uza kuboniswa kwisisombululo esifanelekileyo.
Ngoko, 4K ngumgangatho obalulekileyo kwishishini likamabonwakude. Nangona kunjalo, sisebenzisa iipilisi zethu ezininzi kunoko nje ukuhambisa iividiyo ezivela kwiNetflix ne-Prime Prime ka-Amazon . Ngoko ngokubhekiselele kwipilisi, igama elithi "4K" lingenanto ebalulekileyo.

I-Retina Bonisa vs 4K
Ngokuthengwa kwethebhulethi , igama elithi "4K" limele lixhalabele ukuba ukusetyenziswa kwakho okuphambili kukusebenzisa ifowuni ukubukela umabonwakude kunye nokuhambisa umboniso wevidiyo. Inombolo yangempela ukujonga ngayo iipekseli-intshi nganye (PPI) yomboniso. I-PPI inqunywe ngokusekelwe kwisayizi yeskrini kunye nesisombululo seskrini. Uninzi lwezibhebhile ngoku zibonisa i-PPI kwiinkcukacha.
Iprogram ye -iPad ye-9.7-intshi i-9.7-intshi yokubonisa ibalwa ngokulinganayo kunye nesisombululo esingu-2,048x1,536. Oku kunika iPPI ye-264, apho i-Apple ibona ngokwaneleyo ukuba yi-Retina Display ye-tablet. I- 12.9-intshi ye- iPad Pro isisombululo se-2,732x2,048, esinika i-PPI ye-264.
Xa ukhangela ithebhulethi, i-PPI yeenxa zonke engama-250 okanye ngasentla iyona nto ibalulekileyo ekubetheni i-Retina Display. Khumbula, nantoni na ngaphezu kwe-Retina Display nje ibangela ukuba ithebhulethi iphose iipekseli ezininzi ezonakalisiweyo kwesikrini, ezithatha ubomi obungaphezulu kwebhetri . Inomdla okwaneleyo, i-iPad Mini 4 inePPI ye-326 isekelwe ukuba ibe nesisombululo esifanayo se-iPad Air 2 kunye neskrini esincinci esingu-7.9-intshi. Ngokuqinisekileyo, i-Apple icinga ukuba ukugcina isisombululo esifanayo ukusuka kumbono wokuhambelana kubaluleke ngakumbi kunokuba ibhethri eyongeziweyo kwibhetri, kodwa umboniso ngokwawo ubuya kujonga ngokufanayo kunye nesisombululo esincinci.
Isisombululo se-4K kwithebhulethi kufuneka ngokuqhelekileyo siqwalaselwe kuphela kwiipilisi ezilinganisa iisentimitha eziyi-12 kwi-diagonally okanye ngaphezulu. Yingakho iipilisi zokuqala ezine-4K zihlala zilobukhulu obukhulu. Amacwecwe amancinci anesisombululo se-4K axhoma kwi-bandwagon ukuze kuboniswe umbane oza kudla amandla angaphezulu kwebhetri kodwa anganikeli naluphi na isisombululo esicacileyo ngaphezu kwe-iPad. Ehle kakhulu, u-Sony uvelisa i-smartphone ngesisombululo se-4K.

Xa u-4K & # 39; ngokuqinisekileyo 4K
I-Samsung yakusanda kukhupha i-tablet ye "Galaxy Tab" ye "Galaxy Tab" ye-4K eyenza isisombululo se-2048x1536 esinqunyiwe. Esi sisombululo esifanayo ne-9.7-inch iPad Pro. I-Samsung ithengisa le Galaxy Tab S3 njengebhebhethi ye-4K kuba inokwamukela ividiyo engama-4K nangona ayikwazi ukuyivelisa kwimbonakalo yayo. Oku kubaluleke kakhulu ukuthatha amagama ekuthengiseni i-buzz kwindawo ye-bait-and-switch. Kwakhona kuthetha ukuba ufanele ukungaqiniseki naluphi na umbhebhe obhekiselele ngokwawo u-4K.
Kwaye Kuthiwani NgeTone Eliyinyaniso?
Imiboniso entsha ye-Apple yelayini yayo yePad yeProgram yeePilisi ngoku ibhalwe ngegama elithi "True Tone". Umboniso weTone we-True uyakwazi ukuvelisa i-DCI-P3 iWide Color Gamut, enomgangatho osetyenziswayo kumashishini omculo. Ukunyuka kwi-"Ultra-High Definition" (UHD) kwishishini leTV kuhamba ngokubhekiselele kumbala ombala ngokubanzi ngokuchasene nokwandisa isisombululo seskrini esingu-4K.
Enye into ebonakalayo ye-Apple True Tone boniso yikhono lokubona ukukhanya okubonakalayo kunye nokuguqula umthunzi omhlophe oboniswe kwisikrini ukulinganisa umphumo wokukhanya 'kwihlabathi lenene'. Oku kufana nendlela iphepha elingajonga ngayo elimhlophe ngaphantsi komthunzi kunye nolunye uluhlaza ngaphantsi kwelanga.

Ingaba 4K Ekugqibeleni iya kwiNdlela ye-3D?
Nangona ii-TV ze-3D zibonakaliswe njengenye yefad, iisethi zikamabonwakude ezi-4K zilapha ukuba zihlale. Nangona kunjalo, kunokuthatha ixesha elide kunokuba abanye bacinge nge-4K ukuba babe ngumgangatho oyinyaniso. Kuthatha indawo eyongeziweyo yokugcina ividiyo ye-4K, kwaye ebaluleke ngakumbi, kuthatha i-bandwidth engaphezulu ukusabalalisa i-4K.
Okwangoku ithatha malunga ne-5-6 yeMegabytes-nganye-yesibini (Mbps) ukuhambisa umxholo we-1080p. Ukuba uqwalasela isidingo sokuhlawula kunye nokujongana nokuhamba kwee-Wi-Fi, ii-8 Mbps ziza kuba zilungele. Okwangoku, kuthatha malunga ne-12-15 Mbps ukusabalalisa ividiyo ye-4K, kunye nekhonkco yoxhumo oluphakathi kwe-20 Mbps.
Kwabaninzi abantu, abaya kudla ininzi yebhanti ephuma kuyo kwi-Intanethi. Kwaye nabo babano-50 Mbps banxibelelwano babeza kuziva bexakeke kakhulu xa abantu ababini kwinethiwekhi yabo bezama ukubukela i-movie ye-4K ngexesha elinye.
Kwaye ngelixa sikwazi ukusebenza malunga nombandela, inkampani efana neNetflix okanye iHulu Plus iya kubona ukwanda okukhulu kwindleko zokusasaza ividiyo. I-ISPs ifana neVerizon FIOS kunye neKhamera ye-Time Warner ibhekene nokulwa ngokubhekiselele kwimali ye-bandwidth i-Netflix yodwa ithatha ixesha eliphambili. I-intanethi ngokwayo ingaba yinto engenakunceda xa kukho ukusabalalisa kwamkelwa kwevidiyo ye-4K.
Ngoko asikho apha. Kodwa ukusuka kumbono wexabiso, amathelevishini angama-4K asondela kwaye asondele kumgangatho wabathengi. Kwiminyaka embalwa, ininzi yethu ingacinga ukuba i-$ eyongezelelweyo eyi-100 eyichithwa ukuphucula kwiskrini se-4K iyanele. Kungenokwenzeka ukuba kuthathe ixesha elifutshane ukuba ababoneleli be-intanethi babe yikulungele, kodwa baya kufika khona.
