Ukukhetha i-TV efanele kungaba nzima. I-LED ne-LCD zombili zinikeza izici ezinhle, kodwa iyiphi engcono ngempela? Kulesi sihloko, sizohlola umehluko oyinhloko phakathi Ama-TV e-LED nama-LCD TV. Uzofunda ngokusebenza kwazo, ukonga amandla, nekhwalithi yesithombe, okukusiza ukuthi wenze isinqumo unolwazi.
I-LED vs LCD: Uyini Umehluko?
Ubuchwepheshe obuyisisekelo ngemuva kwe-LCD nama-TV e-LED
Ukuze uqonde umehluko phakathi kwe-LED ne-LCD, kubalulekile ukuqala ngezinto eziyisisekelo.
Ama-LCD TVs (I-Liquid Crystal Display) : Ama-TV e-LCD asebenzisa amakristalu awuketshezi avimba ukukhanya ukuze akhe isithombe. Lezi zikrini zithembele ekukhanyeni kwangemuva, izibani ngokuvamile ezibandayo ze-cathode fluorescent (CCFLs), ezikhanyisa ngamakristalu awuketshezi ukuze zenze okubonakalayo okubona esikrinini.
Ama-TV e-LED (I-Light Emitting Diode) : Ama-TV e-LED empeleni awuhlobo lwe-LCD TV, kodwa asebenzisa ukukhanya kwe-LED esikhundleni sama-CCFL. Lo mehluko oyinhloko uholela ekuthuthukisweni kokukhanya, ukunemba kombala, nokusebenza kahle kwamandla.
Umehluko Obalulekile Kubuchwepheshe Bokubonisa
Umehluko obalulekile phakathi kobuchwepheshe be-LED ne-LCD usehlotsheni lokukhanyisa emuva okusetshenzisiwe. Nakuba ama-TV e-LCD ethembele kuma-CCFL, amakhulu futhi angawongi amandla, ama-TV e-LED asebenzisa ama-diode akhipha ukukhanya amancane, asebenza kahle kakhulu. Lokhu kushintshwa kobuchwepheshe kuvumela ama-TV we-LED ukuthi afinyelele ukugqama okuphezulu, ukukhanya, kanye nekhwalithi yesithombe iyonke. Ama-TV e-LED ayakwazi ukuhlinzeka ngezithombe ezibukhali, ezimhlophe ezikhanyayo nezimnyama ezijulile. Ngokuphambene, izikrini ze-LCD zendabuko zivame ukulwa nokubonisa okumnyama okujulile, ikakhulukazi ezigcawini ezimnyama, ngoba ukukhanya kwangemuva kukhanyiswa ngokufanayo kuso sonke isikrini, okwenza kube nzima ukuzuza ukugqama kwangempela.

Ikhwalithi Yesithombe: Yibuphi Ubuchwepheshe obuletha Okubonwayo Okungcono Kakhulu?
Uma kuziwa kwikhwalithi yesithombe, ama-TV e-LED anenzuzo ecacile ngaphezu kozakwabo be-LCD. Ama-TV e-LED asebenzisa ubuchwepheshe bendawo bokufiphalisa, okuvumela izindawo ezihlukene zesikrini ukuthi zibe namazinga ahlukahlukene okukhanya. Lokhu kubangela ukujula okumnyama nemibala egqamile, ikakhulukazi ezigcawini ezimnyama. Ngokuphambene, ama-LCD anokukhanya okungemuva okukodwa okukhanyisa isikrini sonke ngokufanayo, okungabangela izindawo ezimnyama zibonakale zimpunga futhi kunciphise ukugqama konke. Ukwengeza, ama-TV e-LED angcono ekugcineni ukukhanya nokunemba kombala uma ebhekwa ngama-engeli ahlukahlukene, kuyilapho ama-LCDs angase alahlekelwe ikhwalithi yesithombe uma ebhekwa eceleni, ikakhulukazi mayelana nokukhanya nokugqama.
Ukunemba Kombala kanye nama-engeli wokubuka
Ama-TV e-LED nawo aphakeme ngokunemba kombala nama-engeli wokubuka. Isistimu yokukhanyisa i-LED ivumela uhla olubanzi lwemibala ukuthi iboniswe, okwenza isithombe sigqame futhi sibe namaqiniso. Ukwengeza, ama-TV e-LED athambekele ekulondolozeni ikhwalithi yesithombe engcono kusukela kuma-engeli angaphandle kwaphakathi nendawo, okubalulekile uma ubukele i-TV ezingxenyeni ezihlukene zegumbi. Uma kuqhathaniswa, ama-TV e-LCD angathola ukuhlanekezela kombala kanye nokulahlekelwa ukukhanya uma ebhekwa nge-engeli. Lokhu kwenza ama-TV e-LED abe yinketho engcono kulabo ababeka kuqala ukunemba kombala nama-engeli okubuka abanzi, ikakhulukazi ezindaweni zokubuka ezinkulu noma ezivumelana nezimo.
Ukusebenza Okungcono Kakhulu Ezimeni Ezihlukene Zokubuka
Ama-TV e-LED ahamba phambili ezindaweni ezikhanyayo ngenxa yamazinga awo aphezulu okukhanya. Kungakhathaliseki ukuthi ubukele egumbini lokuhlala elikhanyiswe kahle noma ekamelweni eligcwele ilanga, ama-TV e-LED angakwazi ukubhekana nokukhanya kwe-ambient ngaphandle kokulahlekelwa ikhwalithi yesithombe. Ngakolunye uhlangothi, ama-TV e-LCD angase athwale kanzima ezimweni ezinjalo, ngokungafani okuphansi nemibala ebonakala igezekile. Ama-LCD ajwayele ukwenza kangcono ezindaweni zokukhanya okulawulwayo, njengamagumbi anokukhanya kalufifi, lapho ukusebenza kwawo kungavinjwa imithombo yokukhanya yangaphandle. Ngakho-ke, uma unekamelo elikhanyayo, i-TV ye-LED cishe izokunikeza umuzwa ongcono kakhulu wokubuka.

Ukusebenza kahle kwamandla: Inzuzo ye-LED
Uma kubhekwa ukusetshenziswa kwamandla, ama-TV e-LED asebenza kahle kakhulu kunama-LCD. Ukukhanyisa kwe-LED kusebenzisa amandla amancane uma kuqhathaniswa nama-CCFL e-fluorescent asetshenziswa kuma-LCDs. Isibonelo, i-TV ye-LED engama-intshi angu-32 ngokuvamile idla cishe ama-watts angu-10 ngaphansi kwe-LCD TV yosayizi ofanayo. Ngokuhamba kwesikhathi, ukusetshenziswa kwamandla okuncishisiwe kuhumusha kube ukonga okukhulu ezikweletini zikagesi. Naphezu kwezindleko eziphakeme zokuqala zama-TV we-LED, ukusebenza kahle kwawo kwamandla kuwenza abe utshalomali olungcono lwesikhathi eside. Ngaphezu kwalokho, ama-TV e-LED anomthelela ophansi kwezemvelo ngoba adla amandla amancane futhi aphila isikhathi eside kunama-LCD, asebenzisa ugesi omningi futhi aneshalofu lesikhathi esifushane.
Idizayini futhi Yakha: Ubuncane kanye Nobuhle
Mayelana nokuklama, ama-TV e-LED anenzuzo enkulu kune-LCDs. Isistimu yokukhanyisa i-LED ehlangene neyonga amandla ivumela amaphaneli e-TV azacile. Ama-TV e-LED angaba nomzimba omncane ngokukodwa kokuthathu kunama-LCD TV anosayizi ofanayo, okuwenza alungele amakhaya esimanje lapho ubuhle kanye nesikhala kucatshangelwa khona. Amaphrofayili abo amancane awenza afanelekele ukukhwezwa odongeni noma izindawo zokuhlala ezincane. Ngokuphambene, ama-LCD TV ajwayele ukuba mkhulu ngenxa yobukhulu bama-CCFL, adinga iphaneli enkulu. Ngenxa yalokhu, ama-LCD TV awafaneleki kangako imiklamo yesimanje futhi angase angahlangani kahle ngaphakathi kwesimanjemanje, okukhathalela isikhala.
Izindleko Nenani: Ingabe I-LED Iwufanele Ukutshalwa Kwezimali?
Ama-TV e-LED ngokuvamile afika nenani eliphakeme kunawo wonke ama-LCD ngenxa yobuchwepheshe bawo bokukhanyisa okuseqophelweni eliphezulu nokusebenza kwawo okuphezulu. Nokho, nakuba ama-LCD ethengeka kakhulu futhi angaba inketho enhle kulabo abasebenzisa isabelomali, angase anganikezi inani elifanayo lesikhathi eside. Ama-TV e-LED ahlala isikhathi eside, aphila isikhathi eside, futhi ahlinzeka ngokusebenza kahle kwamandla, okuwenza abe utshalomali oluhlakaniphe ngokuhamba kwesikhathi. Ama-TV e-LED angahlala amahora afika ku-100,000, kanti ama-LCD ahlala cishe amahora angama-50,000. Ngisho noma ama-TV e-LED angase abize kakhulu kusengaphambili, ukuphila kwawo okude kanye nezindleko eziphansi zokusebenza kuwenza abe yisinqumo esibaluleke kakhulu ngokuhamba kwesikhathi.
Ukuphila Isikhathi Eside Nokuqina kwe-LED vs LCD
Ukuqina kwama-TV we-LED kungenye yezinzuzo ezibalulekile eziwenza abe utshalomali olungcono uma kuqhathaniswa nama-LCD. Ukukhanyisa kwe-LED kumelana kakhulu nokonakaliswa ngokuhamba kwesikhathi, okuqinisekisa ukuthi ikhwalithi yesithombe ihlala injalo isikhathi eside. Ngokuphambene, ukukhanya okungemuva kwe-fluorescent okusetshenziswa kuma-LCD kuvame ukuwohloka ngokushesha okukhulu, okungaholela ekukhanyeni okufiphalayo kanye nokukhiqizwa kabusha kombala okungekuhle ngemva kokusetshenziswa isikhathi eside. Lokhu kuphila isikhathi eside kungesinye sezizathu zokuthi kungani ama-TV e-LED, naphezu kokuba ebiza kakhulu ekuqaleni, anikeze inani elingcono ngokuhamba kwesikhathi.
Yikuphi Okungcono Ngokudlala: I-LED noma i-LCD?
Kubadlali bamageyimu, ama-TV e-LED ayisinqumo esingcono. Zinikeza izikhathi zokuphendula ezisheshayo, izilinganiso eziphakeme zokungafani, nokunemba okungcono kombala, konke okubalulekile ukuze uthole umuzwa wegeyimu oshelelayo nogxilile. Izibonisi ze-LED-backlit ziqinisekisa ukuthi izinto ezihamba ngokushesha kumageyimu wevidiyo zinikezwa ngokucacile, ngaphandle kokufiphala kokunyakaza. Ama-LCD, ngenkathi asanikeza ukusebenza okuhle, angase angafani nezikhathi zokuphendula kanye nekhwalithi ebonakalayo yama-TV we-LED, ikakhulukazi uma kuziwa emidlalweni yesenzo esiphezulu. Kodwa-ke, kubadlali abavamile noma labo abakubhajethi, ama-TV e-LCD asengahlinzeka ngomuzwa wokudlala owanelisayo, nakuba ukukhiqizwa kombala okuphezulu nokugqama kwama-TV we-LED kuwenza inketho ekhethwayo yabadlali abazimisele.
