Yintoni i-UHD? Umgangatho wesisombululo somboniso

Inkcazo ephezulu kakhulu (UHD) inceda ukukhokela abathengi ukuya kwimiboniso ekumgangatho ophezulu. Ngokusisiseko, ibhekisa kwizikrini ezinesisombululo esibukhali, imibala yokwenyani ebomini, kunye nentshukumo egudileyo kunezikrini zeHD eziqhelekileyo.

Nangona uninzi lucinga ukuba i-UHD ibhekisa kwizikrini ezinesisombululo se-3,840 x 2,160 (okanye i-4K), eli gama libandakanya izigqibo eziphezulu ezifana ne-5K kunye ne-8K. Abantu nabo bayabhideka UHD ngophawu olufana neCrystal UHD, ebhekisa kwiiphaneli zeLCD.

Khumbula ukuba i-UHD inceda kuphela abathengi ukuba bachonge iziboniso ezikumgangatho ophezulu kwaye bangabhekiseli kwitekhnoloji ethile. Ngokutsho kwe-CEA, isikrini sifanelekile njenge-Ultra HD ukuba inobuncinci besisombululo se-4k kunye ne-16: i-9 ye-aspect ratio.

Yintoni i-OLED? Itekhnoloji yokubonisa

Ngokungafaniyo nezikrini ezininzi ze-UHD, Iimpawu zedayitile ekhanyisa ukukhanya (ii-OLED) zenza ukukhanya kunye nemifanekiso ngokuthe ngqo. Ezi ziboniso zixhaphake kakhulu kwii-smartphones, iilaptops, iitafile, kunye neemonitha, kwaye abathengi abaninzi bakhetha kubo kumnyama wabo onzulu kunye nokwahluka kwemibala emangalisayo. 

Le teknoloji iyenza njani into enjalo? Ngokuvula kunye nokucima i-diode nganye ngombane. Umzekelo, iidiode ziya kuvala ngokupheleleyo xa kusenziwa umnyama, zenza ezona pixels zimnyama nabani na onokuzifumana namhlanje.

Nangona kunjalo, ukuchasana kombala okhethekileyo kunye nomgangatho womfanekiso ayisiyiyo kuphela inzuzo Izikrini ze-OLED. Bakwanceda abavelisi ukuba benze iitafile, ii-smartphones, kunye neelaptops ezincinci kwaye zixinene ngakumbi. Kuba abafuni ukukhanyiselwa ngasemva, kukho indawo eyongezelelweyo yoyilo olumfiliba nolwanamhlanje.

UHD vs. OLED: Zonke iiyantlukwano abathengisi kufuneka bazi

1. UHD vs. OLED: Amanqanaba ombala kunye nomnyama

Kwiminyaka, Izikrini ze-OLED yalawula zonke izinto ukuchaneka kombala. Nangona kunjalo, ukukhanya kwasemva kubone inkqubela phambili emangalisayo (ingakumbi ukuqaliswa kwetekhnoloji yokukhanya kwe-quantum), ibasondeze kwinqanaba lokusebenza kwe-OLED.

Namhlanje, zininzi Izixhobo ze-Ultra HD yiza noluhlu lwemibala engakholelekiyo, ebavumela ukuba babonise ii-hues ezingakumbi. Nangona kunjalo, umgangatho womfanekiso wesikrini usaxhomekeke kwindlela enokuvelisa ngayo iithowuni ezinzulu, ezimnyama-zizona zinto ziphambili ekudaleni imibala etyebileyo kunye nokwahluka olomeleleyo.

Izikrini ze-OLED zilawula olu hlobo. Bagqwesa ekuveliseni imiboniso emnyama yokwenyani kwaye banikezela ngomlinganiselo ophantse ufaniswe womahluko. Nangona izikrini ze-UHD zisebenzisa itekhnoloji ye-Full-Array Local Dimming (FLAD) ukuhambisa abamnyama abanomtsalane, azihambelani nokusebenza kunye nobunzulu be-OLED.

2. UHD vs. OLED: Bonisa iteknoloji kunye nexabiso

Abahloli be-UHD badibanisa itekhnoloji ye-LCD ephucukileyo kunye nokukhanya kwe-LED ngasemva ukwenza imbonakalo yabo. Okuchasene, Imonitha ye-OLEDs sebenzisa iikhompawundi eziphilayo ukuvelisa ukwalathisa ukukhanya, ukususa imfuneko yokukhanyisa kwakhona. Olu yilo lunika izikrini ze-OLED ii-engile ezingcono zokujonga, imibala echanekileyo, kunye nochaso olubukhali kunee-UHD ezahlukeneyo.

Okubaluleke ngakumbi, izikrini ze-OLED zihlala zibiza kakhulu kune Imiboniso ye-UHD kuba iteknoloji ibiza kakhulu ukwenza. Nangona kunjalo, abathengi abanohlahlo lwabiwo-mali olukhulu banokufumana izikrini ze-OLED ezineempawu ze-UHD. Kwelinye icala, izikrini ze-UHD zifikeleleka ngakumbi kodwa zinokukhupha isipaji xa zijolise kwiimodeli ze-4 K.

3. I-OLED vs. I-Ultra HD: Ukusetyenziswa kwamandla

Izikrini ze-OLED zisebenza ngamandla kune-LCDs kwimifanekiso emininzi, zisebenzisa kuphela i-60% ukuya kwi-80% yamandla. Ukuba abathengi babukela kakhulu imifanekiso emnyama, baya kusebenzisa nangaphantsi-malunga ne-40% yamandla eLCD. Nangona kunjalo, ukubonisa imvelaphi emhlophe eqaqambileyo (njengamaxwebhu okanye amaphepha ewebhu) kunokutya ukuya kuthi ga kathathu amandla angaphezu kweLCD.

Kwelinye icala, yahlukile kwi Izikrini ze-UHD. Ukusetyenziswa kwamandla abo ngokwesiqhelo kuyenyuka ngobungakanani bescreen esikhulu kunye nezigqibo eziphezulu. Ngokwe-avareji, i-55-intshi yesikrini se-UHD sisebenzisa malunga ne-77 watts, ngelixa i-4k ibonisa i-80 watts.

4. UHD vs. OLED: Ukuchasana kunye nokuchaneka kombala

Izikrini ze-OLED zinomlinganiselo ongcono kakhulu wokuchasana kunye nokuchaneka kombala kunemiboniso ye-UHD. Kuba banokucima ipikseli nganye, ii-OLED zinokuvelisa abamnyama bokwenyani kunye nokwahluka okumangalisayo. Ngokuchaseneyo, Izikrini ze-UHD ukulwa nokuchaneka kombala ngenxa yokukhanyisa kwabo. Ngokuqhelekileyo kudala ukungafani okuphantsi kunye nabamnyama abahlanjiweyo.

5. UHD vs. OLED: Ubukhali kunye nokucaca

I-UHD ibonelela ngokubukhali okumangalisayo kunye nokucaca, iyenza igqibelele kwimbonakalo ehamba ngokukhawuleza. Ngokumataniswa, Imiboniso ye-OLED ngamanye amaxesha inokuba nzima nokufiphala kwentshukumo okanye ukushiyeka xa uphethe imifanekiso ekhawulezayo.

6. UHD vs. OLED: Ukukhanya kunye nee-angles zokujonga

Enkosi kwitekhnoloji yokukhanyisa kwakhona, Izikrini ze-UHD ziqaqambile kune OLED. Inxalenye engcono? Ezi zikrini zidibene netekhnoloji ye-quantum dot, iqinisekisa ukuba ababukeli bayonwabela ukuqaqamba okungaguqukiyo nokuba singakanani na isikrini.

Oko kwathiwa, IiOLED bazibambe kolu didi nangona bebeka phambili abantsundu nzulu. Banikezela umahluko omangalisayo phakathi kokukhanya kunye neendawo ezimnyama, nangona ukusebenzisa ukukhanya okuphezulu ixesha elide kuya kuwisa ubomi besikrini.

Ukongeza, i-OLED ibetha i-UHD xa isiza ekujongeni ii-angles. Ingaphezulu lee, ngenxa yeepikseli ezikhanyayo ze-OLED eziqinisekisa ukuba ababukeli banokufumana umgangatho womfanekiso ongaguqukiyo kuyo nayiphi na i-engile. Nangona kunjalo, izikrini ze-UHD zinokuzabalaza nemiba ye-pixel shutter, echaphazela ukucaca.

7. I-OLED TV vs. UHD TV: Izinga lokuhlaziya kunye nokuthuthuzela kwamehlo

Ukukhawuleza kangakanani iteknoloji nganye yesikrini ukuhlaziya isiboniso sayo? Imiboniso ye-OLED ngokubanzi banamaxabiso akhawulezayo kune-UHDs kwaye banenzuzo ecacileyo kwindawo yokuthuthuzela iliso, nayo. Nantsi inyani enomdla: iimonitha ze-ultra HD ikhupha ukuya kuthi ga kwi-66% yokukhanya okuluhlaza okwesibhakabhaka, ngelixa i-OLED ikhupha kuphela i-33%, ibenza ukhetho olunempilo ekusebenziseni ixesha elide.

Isigwebo sokugqibela

Ke, kufuneka abathengisi bathenge i-UHD okanye rajanud izikrini? Ewe, ngubani othi abanakuzithengisa zombini? Izikrini ze-OLED zibhenela kuye nabani na ojonge owona mgangatho wemifanekiso ubalaseleyo kunye namava okubukela. Ezinye iimodeli zibonelela ngeenzuzo ze-UHD ukuba abathengi bazimisele ukuzihlawulela. Kwelinye icala, i-UHD ingaphezulu kokwaneleyo kuye nabani na okhangela isikrini esilungileyo semidlalo yevidiyo kunye nemidlalo yekhompyuter (kunye neefowuni zevidiyo).
