1. isingeniso
Ukusetshenziswa kwezikrini ze-LED nezikrini ze-FHD sekusakazeke kakhulu, kudlulela ngalé kwamathelevishini ukuze kufakwe iziqapha nezindonga zevidiyo ze-LED. Yize zombili zingasebenza njengokukhanyisa ngemuva ezibonisini, zinokuhluka okuhlukile. Abantu bavame ukubhekana nokudideka lapho bekhetha phakathi kwesibonisi se-LED noma isibonisi se-FHD. Lesi sihloko sizohlaziya lo mehluko kabanzi, sikusize uqonde kangcono izici nezinhlelo zokusebenza ezifanele ze-FHD nezikrini ze-LED.
2. Iyini i-FHD?
I-FHD imele i-Full High Definition, ngokuvamile enikeza ukulungiswa kwamaphikseli angu-1920 × 1080. I-FHD, okusho incazelo ephezulu egcwele, ivumela ama-TV e-LCD asekela ukulungiswa kwe-FHD ukuthi abonise ngokugcwele okuqukethwe lapho umthombo ungu-1080p. Igama elithi “FHD+” libhekisela enguqulweni ethuthukisiwe ye-FHD, ebonisa ukulungiswa kwamaphikseli angu-2560×1440, okunikeza imininingwane eyengeziwe nombala.
3. Yini i-LED?
Ukukhanyisa kwe-LED kubhekisela ekusetshenzisweni kwe-Light Emitting Diode njengomthombo wokukhanya wangemuva wezibonisi zekristalu eliwuketshezi. Uma kuqhathaniswa nokukhanyisa isibani se-cathode fluorescent (CCFL) esivamile, ama-LED anikeza ukusetshenziswa kwamandla okuphansi, ukukhiqiza ukushisa okuncane, ukukhanya okuphezulu, nokuphila isikhathi eside. Isibonisi se-LED sigcina ukukhanya kwawo ngokuhamba kwesikhathi, sizacile futhi siyathandeka ngokwengeziwe, futhi sinikeza iphalethi yombala ethambile, ikakhulukazi uma ihlanganiswe nephaneli yesikrini esiqinile, okuyenza ikhululeke kakhudlwana emehlweni. Ukwengeza, wonke ama-backlights e-LED anezinzuzo zokuwonga amandla, angavumeli imvelo, kanye nemisebe ephansi.
4. Yikuphi Okuhlala Isikhathi Eside: FHD noma LED?
Ukukhetha phakathi kwezikrini ze-FHD neze-LED zokusetshenziswa isikhathi eside kungase kungabi lula njengoba ucabanga. Izikrini ze-LED ne-FHD zibonisa amandla ahlukene ezicini ezihlukahlukene, ngakho ukukhetha kuncike ezidingweni zakho siqu kanye nezimo zokusebenzisa.
Izikrini zokukhanyisa kwe-LED ngokuvamile zinikeza ukukhanya okuphezulu nokusebenzisa amandla aphansi, okuzenza zonge amandla futhi ziqine ukuze zisetshenziswe isikhathi eside. Ukwengeza, izikrini ze-LED zivame ukuba nezikhathi zokuphendula ngokushesha nama-engeli okubuka abanzi, okuholela kuvidiyo eshelelayo necacile nesipiliyoni sokudlala.
Ngakolunye uhlangothi, izikrini ze-FHD zivame ukuba nokulungiswa okuphezulu kanye nekhwalithi yesithombe enemininingwane eminingi, okuzenza ziphakame kakhulu ekubukeni amavidiyo nezithombe ezinencazelo ephezulu. Kodwa-ke, izikrini ze-FHD zivame ukudinga ukusetshenziswa kwamandla okuphezulu kanye nezikhathi zokuphendula ezinde, ezingase zithinte ukusebenza kwazo phakathi nokusetshenziswa okunwetshiwe.
Ngakho-ke, uma ubeka phambili ukusebenza kahle kwamandla nokuqina, isikrini esikhanyiselwe emuva kwe-LED singaba inketho engcono. Uma ubeka ukubaluleka okukhulu kukhwalithi yesithombe nokulungiswa, khona-ke isikrini se-FHD singase sifaneleke kakhulu. Ekugcineni, ukukhetha kuncike ezidingweni zakho ezithile kanye nezimo zokusebenzisa.
5. I-LED vs. FHD: Iyiphi Evumelana Nemvelo Kakhulu?
Ngokungafani ne-FHD,Izikrini ze-LEDziyindlela evumelana nemvelo. Uma kuqhathaniswa nokukhanyisa okuvamile kwe-fluorescent, izikrini ze-LED zisebenzisa amandla amancane futhi zinikeza impilo ende.
Ngaphezu kwalokho, ubuchwepheshe be-backlight ye-LED buhlinzeka ngokugqama okuphezulu kanye ne-gamut yombala obanzi, iletha izithombe ezicacile nezigqamile. Ngokombono wemvelo, izikrini ze-LED ngokungangabazeki ziyisinqumo esingcono kakhulu.
6. Ukuqhathaniswa Kwamanani: I-LED vs. FHD Izikrini Zosayizi Ofanayo
Umehluko wamanani phakathi kwezikrini ze-LED ne-FHD ezinosayizi ofanayo ikakhulukazi uncike ezinqubweni zazo zokukhiqiza, izindleko zezinto ezibonakalayo, kanye nezinga lobuchwepheshe elisetshenziswayo. Izikrini ze-LED ngokuvamile zisebenzisa ubuchwepheshe be-LED obuthuthukisiwe kanye nemiklamo yamandla aphansi, okuvame ukuholela ezindlekweni eziphezulu. Ukwengeza, izikrini ze-LED zidinga idizayini yokuphatha okushisayo eyengeziwe, okwandisa izindleko zokukhiqiza. Ngokuphambene, izikrini ze-FHD ngokuvamile zisebenzisa ubuchwepheshe be-CCFL bendabuko, obunenqubo yokukhiqiza elula nezindleko eziphansi. Ngakho-ke, kungase kube khona umehluko ezindlekweni zezinto ezibonakalayo phakathi kwezikrini ze-LED neze-FHD ezinosayizi ofanayo.
7. Izimo Zokusebenza: Lapho Izikrini ze-LED ne-FHD Zikhanya khona
Isikrini se-LED sinezici zokukhanya okuphezulu, i-engeli yokubuka ebanzi kanye nokumelana nesimo sezulu esiqinile, okwamanje emkhakheni wokuboniswa, ibhodi lokukhangisa langaphandle, isibonisi esikhulu se-LED,isikrini se-LED sesitejifuthiisibonisi se-LED yesontozithandwa ikakhulukazi phakathi kwabantu. Kusukela kumabhodi amakhulu ezifundeni zezentengiselwano kuya ezizindeni zesiteji ezinhle kakhulu zamakhonsathi, imiphumela yokubonisa yezikrini ze-LED eguquguqukayo kanye nokukhanya okuphezulu idonsa ukunaka, iba yindlela ebalulekile yokulethwa kolwazi nokuzijabulisa okubukwayo. Ngokuthuthuka kwezobuchwepheshe, ezinye izibonisi ze-LED ezisezingeni eliphezulu manje zisekela i-FHD noma izinqumo eziphakeme nakakhulu, okwenza ukukhangisa kwangaphandle nezibonisi ezinkulu ezinemininingwane eminingi futhi ezicace kakhudlwana, okuqhubeka nokwandisa ububanzi bokusebenza bezikrini ze-LED.
Izikrini ze-FHD, ezimele ukulungiswa kwe-HD egcwele, zisetshenziswa kakhulu ekuzijabuliseni kwasekhaya, amathuluzi okukhiqiza asehhovisi, nasezindaweni zokufunda nokufunda. Ekuzijabuliseni kwasekhaya, amathelevishini e-FHD anikeza ababukeli izithombe ezicacile nezinemininingwane, okuthuthukisa umuzwa wokubuka ojulile. Kuzilungiselelo zehhovisi, iziqaphi ze-FHD zisiza abasebenzisi ukuthi baqedele imisebenzi kahle ngokulungiswa kwabo okuphezulu nokunemba kombala. Ukwengeza, kwezemfundo, izikrini ze-FHD zisetshenziswa kakhulu emakilasini e-elekthronikhi nasezinkundleni zokufunda eziku-inthanethi, ezinikeza abafundi izinto zokufunda ezibukwayo ezisezingeni eliphezulu.
Kodwa-ke, ukusetshenziswa kwezikrini ze-LED ne-FHD azihlukene ngokuphelele, njengoba zivame ukugqagqana ezimeni eziningi. Isibonelo, ekubonisweni kwezentengiso nasekukhangiseni, izikrini ze-LED, uhlobo oluyinhloko lokukhangisa kwangaphandle, zingahlanganisa i-FHD noma amayunithi wokubonisa anokulungiswa okuphezulu ukuze kuqinisekiswe ukuthi okuqukethwe kuhlala kucacile futhi kufundeka ngisho nalapho ukude. Ngokufanayo, izindawo zentengiso zasendlini zingasebenzisa ubuchwepheshe bokukhanya kwe-LED obuhlanganiswe nezikrini ze-FHD ngokukhanya okuphezulu kanye nemiphumela yokugqama okuphezulu. Ukwengeza, kumakhonsathi abukhoma nasemicimbini yezemidlalo, izikrini ze-LED kanye ne-FHD noma amakhamera anokulungiswa okuphezulu nezikrini zokusakaza zisebenza ndawonye ukuze zilethe okuhlangenwe nakho okubonakalayo okumangalisayo kwezethameli.
8. Ngale kwe-FHD: Ukuqonda i-2K, 4K, ne-5K Resolutions
1080p (FHD – Incazelo Ephezulu Egcwele):Isho ividiyo enencazelo ephezulu enokulungiswa kwamaphikseli angu-1920×1080, ifomethi ye-HD evame kakhulu.
I-2K (QHD – Quad High Definition):Ngokuvamile ibhekisela kuvidiyo enencazelo ephezulu enokulungiswa kwamaphikseli angu-2560 × 1440 (1440p), okuphindwe kane kune-1080p. Izinga le-DCI 2K lithi 2048×1080 noma 2048×858.
I-4K (UHD – Ultra High Definition):Ngokuvamile ibhekisela kuvidiyo enencazelo ephezulu kakhulu enokulungiswa kwamaphikseli angu-3840 × 2160, okuphindwe kane kwe-2K.
I-5K UltraWide:Ifomethi yevidiyo enokulungiswa kwamaphikseli angu-5120×2880, eyaziwa nangokuthi i-5K UHD (I-Ultra High Definition), enikeza ukucaca okuphakeme nakakhulu kune-4K. Ezinye izikrini ze-ultrawide eziphezulu zisebenzisa lesi sinqumo.
9. Isiphetho
Kafushane, zombili izikrini ze-LED nezikrini ze-FHD zinezinzuzo zazo. Okubalulekile wukunquma ukuthi yiziphi izici ozidingayo nokuthi yiluphi uhlobo olufanelekela kangcono izidingo zakho ezithile. Kungakhathaliseki ukuthi ukhetha ini, inketho engcono kakhulu yileyo ehlangabezana nezidingo zakho. Ngemva kokufunda lesi sihloko, kufanele ube nokuqonda okujulile kwezikrini ze-LED ne-FHD, okukuvumela ukuthi ukhethe isikrini esizifanela kangcono izidingo zakho.
I-RTLEDingumkhiqizi wesibonisi we-LED onolwazi lweminyaka engu-13. Uma unentshisekelo kulwazi olwengeziwe lokubonisa,xhumana nathi manje.
