Elinye ixeshana onokuyiva xa uthelekisa imodeli ehlukeneyo yeethelevishini "yi-LED ejikelezayo." Abathengi badibana nokudideka xa kufikelele kwiintlobo ezahlukeneyo zeTV ezikhoyo namhlanje kunye nobuchwepheshe bezobugcisa. Ngokwengxenye, kuba ngabavelisi bavame ukukhuthaza ukufaneleka kwetheknoloji ethile ngaphandle kokuyichaza ngokupheleleyo kwaye banike amagama abo asemthethweni.
Okokuqala, kufuneka ukwazi ukuba zonke ii-TV ze-LED zihlobo lwe-TV ye-LCD ; "I-LED" ibhekisela kuphela kumthombo wokukhanyisa osetyenziswayo ukukhanyisa ii-pixels ze-LCD kumabonwakude. Imiba enzima ngakumbi kukuba kukho indlela engaphezulu kweyodwa yokukhanyisa iipekseli. Iingcali ezimbini zobuchwepheshe zibukhali kwaye zipheleleyo.
I-LED ye-Edge-Lit
Umabonwakude ogqityiweyo woluhlu luyimodeli apho ii-LED ezikhanyisa ii-pixels ze-LCD zifumaneka kuphela kwimida yesethi. Ezi LED zijongene ngaphakathi ngaphakathi kwesikrini ukuze zikhanyise.
Oku kuvumela ukuba le mizekelo ibe mncinci kwaye ilula. Benza oku kwiindleko ezincinci zobunjani bomfanekiso-ngokukodwa kwindawo yamnyama. Imimandla emnyama emfanekisweni, njengobusuku obusuku apho kubonakala khona ubumnyama, abukho mnyama mnyama, kodwa kubonakala ngathi unjengomthunzi omnyama ngenxa yokuba ukukhanya kuvela emaphethelweni kwaye kukhanyisa indawo emnyama ngakumbi.
Kweminye imizekelo yee-LED ezibhekiselele kumgangatho ongezantsi, ukulingana komfanekiso kungabangela ingxaki. Ngenxa yokuba ii-LED zifumaneka kwimida yepaneli, njengoko usondela phakathi kwesikrini, ukuncipha kwexabiso kuba umlinganiselo ofanayo wokukhanya awufikeli iipekseli ezikude kude nemida. Kwakhona, oku kuphawuleka ngakumbi ngexesha lobumnyama; abamnyama emacaleni kwesikrini ungcono kunomnyama (kunye neembombo zingabonakala zibe nekhwalithi efana ne-flashlight ebonakalayo evela kwiikona).
I-LED epheleleyo
I-LED epheleleyo ibhekiselele kumabonakude asebenzisa iipaneli ezipheleleyo ze-LED ukukhanyisa iipikseli. Uninzi lwala maqoqo luneenkcukacha zendawo, oku kuthetha ukuba ii-LED ziyakuncipha kwimimandla eyahlukeneyo yepaneli ngelixa ezinye iindawo zingekho. Oku kunceda ukuphucula amanqanaba omnyama, okubonakala ngathi kufutshane nomnyama kunomnyama omnyama.
Iithelevishini ezipheleleyo zivame kakhulu kwaye zinzima kunemizekelo ekhutshwayo.
I-Edge-Lit Versus LED epheleleyo
Ngokubanzi, i-LED eneenkcukacha ezipheleleyo ithathwa njengeteknoloji ephezulu xa ifika kumgangatho wesithombe, kodwa iisethi ezibhekiselwe kumaphethelo zinenzuzo enkulu enkulu: ubunzulu. Iimvumi ze- LED ezidibeneyo ezidibeneyo zingaba mncinci kunezo zidibene kunye nepaneli epheleleyo ye-LED okanye i-backoffcent yendalo (engekho i-LED). Ngenxa yeso sizathu, uninzi lwezinto ezinqwenelekayo ezibekayo ozibonayo kwiivenkile ziza kubakho.
Yiyiphi iteknoloji efanelekileyo kuwe? Oku kuxhomekeke kwinto ofuna.
Ukuba ukhangele umgangatho ophezulu kakhulu wesithombe, unako ukuwufumana kwisiboniso esipheleleyo se-LED kunye ne-dimming local. Ukuba ukhathazeke ngokukodwa malunga nokubonakala komabonwakude kwaye ufuna isethi esincinci kakhulu, i-edge-lit bed isitayela esiya kufana neemfuno zakho.
