Iyini I-TV ye-LED nokuthi Ithuthukisa Kanjani Ikhwalithi Yesithombe

Ezweni lanamuhla, Ama-TV e-LED  abe yisinqumo esidumile kubathengi abafuna ikhwalithi yesithombe ephezulu nokusebenza kahle kwamandla. Nokho, kuvame ukudideka mayelana negama elithi 'i-TV ye-LED.' Abantu abaningi bacabanga ukuthi libhekisela ohlotsheni oluhluke ngokuphelele lobuchwepheshe bethelevishini, kodwa empeleni, ama-TV e-LED awuhlobo oluncane lwama  -LCD TV  asebenzisa  ama-light-emitting diode (LEDs)  njengesibani sawo sangemuva. Kulesi sihloko, sizohlola ukuthi ayini ama-TV e-LED, asebenza kanjani, izinhlobo zawo, izici, nokuthi yini ewenza abe ukukhetha okuphezulu kubathengi banamuhla.

Ukuqonda i-TV ye-LED

Iyini i-TV ye-LED?

Empeleni, i  -LED TV  imane nje iyi-  LCD TV  enokukhanyisa  kwe-LED . Ubuchwepheshe obusetshenziswa esikrinini ngokwaso, i-liquid crystal display (LCD), buyafana namamodeli amadala, kodwa isistimu yokukhanyisa ithuthukisiwe isuka ku  -CCFL (Cold Cathode Fluorescent Lamps)  yaba  ama-LED . Lokhu kushintsha kuthuthukisa ukukhanya, ukugqama, nokusebenza kahle kwamandla kuyilapho kuvumela imiklamo emincane nelula.

Imelelani i-TV ye-LED?

I-LED imele i-  Light Emitting Diode . Ngokungafani nama-LCD TV amadala  e-CCFL-backlit LCD  , abesebenzisa izibani ezikhanyayo ukuze zikhanyise isikrini, ama-TV e-LED asebenzisa lawa ma-diode amancane ukuze adale ukukhanya. Ama-LED diode kuma-TV we-LED awonga amandla, ahlala isikhathi eside, futhi ayakwazi ukuletha ukukhanya okuphakeme uma kuqhathaniswa nama-CCFL. Lolu shintsho luholele kukhwalithi yesithombe engcono, emnyama ejulile nemibala egqamile.

Isebenza kanjani i-LED Backlighting?

Ukukhanyisa kwe-LED kuyinqubo lapho ama-LED asetshenziswa ukukhanyisa isikrini se-LCD. Nakuba  amakristalu awuketshezi  engakhiphi ukukhanya ngokwawo, aphatha ukukhanya okukhiqizwa ama-LED ukuze adale izithombe. Empeleni,  ama-LED  ahlinzeka ngomthombo wokukhanya odingekayo ukuze amakristalu awuketshezi alawule. Lokhu kukhohlisa kokukhanya kuvumela ukulawula okunembe kakhudlwana kwekhwalithi yesithombe, okwenza ama-TV e-LED abe inketho ekhangayo kulabo abafuna ukusebenza okuphakeme.

Izinhlobo Zokukhanyisa kwe-LED kanye Nomphumela Wazo

Ama-TV e-LED awadalwanga alinganayo. Kunezinhlobo eziningi ezahlukene zobuchwepheshe bokukhanyisa i-LED, ngayinye inezinzuzo zayo. Ukuqonda lo mehluko kungakusiza wenze isinqumo esinolwazi lapho uthenga i-TV entsha.

I-Edge-Lit LED Technology

Ama-TV e-Edge-lit LED  anama-LED abekwe emaphethelweni esikrini. Isibani sibe sesisakazwa kuso sonke isikrini kusetshenziswa inkomba yokukhanya. Lo mklamo uvumela ama-TV amancane, awenze alungele izinto zangaphakathi zesimanjemanje, ezincane. Nokho, ukukhanya okukhanyisa onqenqemeni kungase kuholele ekukhanyeni okungalingani, ikakhulukazi ezigcawini ezimnyama, njengoba ukukhanya kuvela emaphethelweni kuphela.

Izinzuzo:

• Umklamo omncane

Vuselela Amanani Nokuphatha Ukunyakaza

Izinga  lokuvuselela  linani lezikhathi lapho i-TV ibuyekeza khona isithombe ngesekhondi. Izinga lokuvuselela eliphezulu lisho ukunyakaza okushelelayo, ikakhulukazi phakathi nezigcawu ezisheshayo njengezemidlalo noma amamuvi esenzo.

• I-60Hz : Okujwayelekile kumamodeli amaningi weleveli yokungena namaphakathi, anele okuqukethwe okuvamile.

• 120Hz nangaphezulu : Itholakala kumamodeli aphezulu, kunciphisa ukufiphala kokunyakaza phakathi nezigcawu ezihamba ngokushesha. Amanye amamodeli asebenzisa ukuhumusha kokunyakaza ukuze alingise amanani ozimele aphezulu.

Qaphela:  Uma ungumdlali wegeyimu noma umlandeli wezemidlalo,  izinga lokuvuselela elingu-120Hz  libalulekile ukuze uthole umuzwa oshelelayo.

I-HDR (High Dynamic Range) kanye nekhwalithi yesithombe

Ubuchwepheshe be-HDR  buthuthukisa ukugqama nokujula kombala kwezithombe. Ivumela ububanzi obubanzi bamazinga okukhanya, kusukela kokumnyama okujulile kuya kokumhlophe okukhanyayo, okuholela ezithombeni ezinempilo nezifana nempilo.

• I-HDR10 : Ifomethi ye-HDR ejwayeleke kakhulu, enikeza ukujula kombala okungu-10-bit.

• I-Dolby Vision : Ifomethi ye-premium enikeza ukujula kombala okungu-12-bit nokugqama okuphezulu.

• I-HLG : Ifomethi yokusakaza bukhoma kwe-HDR.

Bheka ukusekelwa kwe  -Dolby Vision  uma ufuna ukusebenza kwe-HDR yekhwalithi ephezulu kakhulu.

Ukusebenza kahle kwamandla kanye nokucatshangelwa kwemvelo

Enye yezinzuzo ezibalulekile zama-TV we-LED ukusebenza kwawo kahle kwamandla okumangalisayo. Uma kuqhathaniswa nobuchwepheshe obudala obufana ne-plasma kanye ne-CCFL-backlit LCDs, ama-TV e-LED asebenzisa amandla amancane kakhulu, okuwenza abe yinketho eco-friendly. Lokhu kusetshenziswa kwamandla okuphansi akusizi nje kuphela ekwehliseni i-carbon footprint yakho kodwa futhi kuholela ekongeni okukhulu ezikweletini zikagesi ngokuhamba kwesikhathi. Njengoba izintengo zamandla ziqhubeka nokukhuphuka, ukukhetha ama-TV e-LED kungakusiza wehlise izindleko zamandla zasendlini zesikhathi eside. Idizayini yabo ewonga amandla yenza ama-TV e-LED abe yisixazululo esikahle kubathengi abafuna ukulinganisa ukusebenza nomthwalo wemfanelo wendawo.

Ukusetshenziswa kwamandla kwama-TV we-LED

Ama-TV e-LED asebenzisa ama-light-emitting diode (ama-LED) athuthukisiwe ekukhanyiseni emuva, ubuchwepheshe obungonga kakhulu amandla kunezibani zangemuva ezikhanyayo ezitholakala kuma-LCD TV amadala. Ama-LED adinga ugesi omncane ukuze asebenze, okuhumusha ukwehlisa ukusetshenziswa kwamandla kuyilapho eletha ukusebenza kwesithombe kwekhwalithi ephezulu. Lokhu kwehliswa kokusetshenziswa kwamandla akuzuzisi nje kuphela imali yakho yamandla kodwa futhi kunomthelela omuhle ekusimameni kwemvelo. Ama-TV e-LED ayindlela eluhlaza okotshani emakethe ye-TV, okuwenza abe yinketho ekhethwayo kubathengi abafuna ukunciphisa umthelela wabo wemvelo ngaphandle kokuyekethisa ikhwalithi yokuboniswa.

Ukuqina Nokuphila

Ama-TV e-LED aziwa ngokuqina kwawo okumangalisayo nempilo ende. Ngokwesilinganiso, lawa mathelevishini angahlala amahora afinyelela kwangu-100,000, adlula kakhulu amamodeli amadala afana nama-TV eplasma, avame ukuba nesikhathi esifushane sokuphila. Lokhu kuphila isikhathi eside okunwetshiwe kuqinisekisa ukuthi abathengi bathola inani elikhulu lokutshalwa kwabo, njengoba ngeke badinge ukushintsha i-TV yabo njalo. Ukuqina kwama-TV e-LED kubonakala ekwakhiweni kwawo okuqinile, okuwenza abe ukukhetha okuthembekile futhi okungabizi kakhulu kulabo abafuna isisombululo sokuzijabulisa esihlala isikhathi eside. Uma kuqhathaniswa nezinye izinhlobo zokuboniswa, ama-TV e-LED ayinketho eqinile, yesikhathi eside.
