Igama elilodwa ongase ulizwe uma uqhathanisa amamodeli ahlukene amathelevishini "yi-LED ekhanyayo." Abathengi babhekana nokudideka okuningi uma kuziwa ezinhlobonhlobo zeTVs ezitholakalayo namuhla nobuchwepheshe phakathi kwabo. Ngokwengxenye, kungenxa yokuthi abakhiqizi bavame ukukhuthaza ukufaneleka kobuchwepheshe obuthile ngaphandle kokuchaza ngokugcwele futhi banikeze amagama abo okuthiwa amagama.
Okokuqala, kufanele wazi ukuthi wonke ama-TV e-LED awuhlobo lwe-LCD TV ; "I-LED" ibhekisela kuphela kumthombo wokukhanyisa osetshenziselwa ukukhanyisa amaphikseli e-LCD kuthelevishini. Ukucindezela izindaba nakakhulu ukuthi kukhona indlela engaphezu kweyodwa yokukhanyisa amaphikseli. Ubuchwepheshe obubili obukhulu buphephile futhi bugcwele.
I-Edge-Lit LED
Isithelevishini esiphezulu-ukukhanya iyisibonelo lapho ama-LED akhanyisa amaphikseli e-LCD atholakala kuphela emaphethelweni esethi. Lezi LED zibheke ngaphakathi ngaphakathi kwesikrini ukuze zikhanyise.
Lokhu kuvumela lezi zithombe ukuthi zibe mncane kakhulu futhi zikhanyise. Benza lokhu ngezindleko ezincane zekhwalithi ethile yezithombe-ikakhulukazi endaweni yamazinga amnyama. Izindawo ezimnyama zesithombeni, ezifana nesimo sebusuku lapho kukhonjiswa khona ubumnyama, akuzona abamnyama ngempela, kodwa kubonakala sengathi zifana negrey emnyama ngoba ukukhanya kuvela emaphethelweni futhi kukhanyisa izindawo ezimnyama kancane kancane.
Kwamanye amamodeli wezintambo ezinezintambo eziphoqelekile eziphezu komkhawulo, izinga eliphezulu lesithombe lingaba yinkinga. Ngenxa yokuthi ama-LED atholakala emaphethelweni wephaneli, njengoba usondela phakathi kwesikrini, izinga lokunciphisa ikhwalithi ngoba inani elifanayo lokukhanyisa alifinyeleli amaphikseli akhiwe kude nemiphetho. Nakulokhu, lokhu kuyabonakala nakakhulu phakathi nezigcawu zobumnyama; abamnyama eceleni emaphethelweni esibuko kunamafu kakhulu kunamnyama (futhi amakhondi angabonakala abe nekhwalithi efana ne-flashlight ekhanyayo evela emagumbini).
I-LED egcwele egcwele
I-LED ephelele ibhekisela kumathelevishini esebenzisa iphaneli ephelele yama-LED ukuze ukhanyise amaphikseli. Iningi lalezi zinethi nazo zine-dimming yendawo, okusho ukuthi ama-LED angadalwa ezindaweni ezihlukahlukene zephaneli ngenkathi ezinye izifunda zingekho. Lokhu kusiza ukuthuthukisa amazinga omnyama, avela asondelene nobumnyama kunombunga omnyama.
Amathelevishini aphelele ajwayelekile kakhulu futhi anzima kakhulu kunamamodeli avulekile.
I-Edge-Lit ihambisana ne-LED ephelele
Ngokuvamile, i-LED egcwele ibhekwa njengetheknoloji ephakeme uma kuziwa emkhakheni wezithombe, kodwa ama-edge avuliwe anenzuzo eyodwa enkulu: ukujula. Ama- TV e-LED agijimayo angaba mncane kakhulu kunelawo avuliwe ngephaneli egcwele ye-LED noma i-backlight LED yendabuko (okungewona i-LED). Ngenxa yalesi sizathu, iningi lezinsikazi ezincane kakhulu ozibekayo ezitolo zizobekwa eceleni.
Ngubuphi ubuchwepheshe obufanele kuwe? Lokho kuxhomeke kulokho okufunayo.
Uma ufuna ikhwalithi yesithombe engcono kunazo zonke, cishe ungayithola ekuboniseni okugcwele kwe-LED nge-dimming yendawo. Uma ngokuyinhloko ukhathazekile ngokubukeka kwethelevishini futhi ufuna isethi esincane kakhulu, ukukhanya okukhawulezayo yisitayela esizofanelana nezidingo zakho.
