Izinhlobo ze-Edge LED ne-Direct LED matrix backlight – okungcono nokuthi yini umehluko

Ukukhetha i-LCD LED TV yisixazululo esizohlala iminyaka eminingi, ngakho-ke kufanele unake imingcele yayo ngaphambi kokuthenga. Okudidayo ukuthi, usayizi wesikrini omkhulu nokulungiswa kwe-
4K akuqinisekisi ikhwalithi yesithombe ephezulu kakhulu. Kulokhu okuthunyelwe, sizochaza umehluko phakathi kobuchwepheshe be-Edge LED kanye ne-Direct LED technologies.

Izinhlobo ze-matrix backlight kuma-LCD LED TV

Kusukela ngasekupheleni kwawo-1990s, izikrini ze-LCD seziqalile ukufaka izikrini ze-CRT, ziwakhipha emakethe ngokuphelele. Singathini ngabo ngemva kweminyaka engaphezu kwamashumi amabili sihlala emakhaya ethu? Ama-TV nama-monitor e-LCD awalahlekelwa ukuduma futhi asephezulu. Azikho izikrini ze-plasma, noma i-OLED esemfashinini esanda kudlula kuzo. https://cxcvb.com/texnika/televizor/texnology/amoled-ili-ips-chto-luchshe.html Ngokuhamba kweminyaka, kuphela uhlobo lokukhanyisa kwe-matrix olushintshile. Ngaphambili, amalambu abandayo e-cathode fluorescent (CCFL) ayesetshenziswa ukuze akhanyise, namuhla asetshenziswa kakhulu ama-light-emitting diode (LED) awonga kakhulu. Uma ubheka okunikezwayo kwezitolo eziku-inthanethi, ngokuqinisekile uzothola igama elithi LED TV. Khumbula ukuthi lena yi-LCD TV ekhanyisa kabusha i-LED futhi ayihlanganise lutho nobuchwepheshe be-OLED.

1. I-LED eqondile – ama-diode afakwa ngaphansi kwe-matrix futhi ahlala evuliwe kukho konke ukusebenza kwe-TV. Endabeni yokukhanyisa ngemuva okuqondile, abakhiqizi bavame ukusebenzisa lokho okwaziwa ngokuthi ukufiphala kwendawo ukuze kuzuzwe abamnyama abajulile.
2. I- Edge LED – Ama-LED abekwe emaphethelweni e-matrix. Lesi yisixazululo esonga amandla, kodwa njengoba uzobona kamuva, siholela ekukhanyeni kwesikrini okungalingani.

Indawo yama-LED inomthelela omkhulu kukhwalithi yesithombe. Kuzo zonke ezinye izihloko, sizozama ukudingida ngayinye yalezi zobuchwepheshe ngokuningiliziwe futhi sithole impendulo yombuzo we-Edge LED noma i-Direct LED.

I-Direct LED – i-matrix ye-LED efiphalisayo yendawo ye-TV

I-Direct LED dimming yendawo ubuchwepheshe obuthuthukisiwe obuletha abamnyama abajulile. Ngokusetshenziswa kokulawula ukukhanya kwangemuva, isithombe sithola ikhwalithi engatholakali kuma-TV avamile e-DLED. Ukuqhathanisa okuphezulu kufinyelelwa. Izindawo ezikhanyayo zifiphazwa ngokuzimela, zishiya izindawo ezikhanyayo zibonakala ngokucacile. Lena enye indlela enhle kulabo abafuna i-LED TV kodwa abafuni ukubekezelela ububi be-Direct noma i-Edge. Ezicacisweni ze-TV, ngokuvamile ungathola igama elithi I-Full Array Local Dimming (i-Samsung isebenzisa igama elithi Direct Full Array), lokhu akuyona into engaphezu kwesibani esingemuva esiqondile esinamazoni. Afakwe kuma-TV aphakathi nendawo nasezingeni eliphezulu. Kumamodeli abiza kakhulu, uzothola izindawo ezingafika ku-1000, ezindaweni ezishibhile, ngokuvamile ezingama-50-60 kuphela.

Izinzuzo kanye nokubi kokukhanyisa okuqondile

I-conventional DLED-backlight inezinkinga eziningi ngaphezu kokukhanyisa kwe-matrix. Ama-TV anobuchwepheshe be-Direct LED ngokuyinhloko anezinkinga zokumnyama, okuthi ezikrinini zawo kuvame ukuthatha amathunzi okumpunga. Kodwa-ke, i-Direct LED ayimbi kangako uma ihlanganiswa nokufiphalisa kwendawo. Iqeda iningi lokushiyeka kobuchwepheshe obuyisisekelo. Izithombe zihlala zikhanya futhi zicwebile, kuyilapho izithunzi zijula.

3 ama-TV esimanje ane-Direct LED

I-Samsung UE55TU7097U

Lena i-55″ 4K LED TV esekela i-HDR10+ ne-HLG. Imodeli ifakwe i-Crystal 4K processor, inikeza ikhwalithi yesithombe ephezulu nemibala yemvelo. Uhlelo lwe-Game Enhancer luwusizo kubadlali bamageyimu, luqinisekisa ukunensa kokufaka okuphansi. I-UE55TU7097U futhi inohlu olugcwele lwamashuna, kanye nesilawuli kude semisebenzi eminingi sikwenza kube lula ukulawula i-TV yakho namadivayisi axhunyiwe, kuyilapho i-Tizen System 5.5 ikunikeza ukufinyelela okulula kuzici ezibanzi ze-smart TV. Ubukhulu be-TV enesitendi: 1231x778x250 mm.

I-Sony KD-55X81J

Lena imodeli engu-55-intshi efakwe inzwa engu-4K enezinga lokuvuselela elingu-120 Hz, eliqinisekisa ukushelela kwayo okuphezulu. Umkhiqizi uphinde wanakekela ikhwalithi yayo ngokuhlomisa i-HDR10 +, i-Dolby Vision kanye nemishini ye-HLG, kanye nephrosesa ye-HCX Pro AI, okuthi, ngenxa yobuhlakani bokwenziwa, ikhulise ngokuzenzakalelayo isithombe ukuze sizuze umphumela omuhle kakhulu. Ubukhulu be-TV enesitendi: 1243x787x338 mm.

I-LED eqondile noma i-Edge LED, yikuphi ukukhanya okungemuva ongakhetha nokuthi iyiphi ongayinqaba: https://youtu.be/P0CCeS9R6yU

I-Edge LED – kuyini?

Kuma-TV anobuchwepheshe be-Edge LED, ama-diode okukhanya angemuva amhlophe abekwa kuphela emaphethelweni e-matrix (kumamodeli ashibhile, lokhu kungase kube unqenqema olulodwa noma ezimbili kuphela). Ukuze ukukhanya okuvela kuma-LED kufinyelele ezindaweni ezikude kakhulu, kudingeka imojula ye-LGP ukuyisabalalisa. Izikrini ze-Backlit Edge LED zincane kodwa zinezinkinga ngokukhanya okufanayo. Umugqa owodwa wama-LED awanele ekukhanyisweni okuhle kwakho konke okuqukethwe kwesibonisi, futhi ngisho nemojula ekhethekile ayisizi kakhulu lapha. Ngokuvamile, isithombe sizokhanya kakhulu emaphethelweni kunamaphakathi. Ngesikhathi esifanayo, izindawo ezimnyama ngeke zibe mnyama njengoba kufanele zibe. Kodwa-ke, ama-Edge LED TV anesilinganiso esingcono sokuqhathanisa kunama-TV akhanyayo angemuva.

Izinzuzo kanye nokubi ukukhanyisa onqenqemeni

Ngenxa yenani eliphansi lama-LED, ama-Edge LED TV ashibhile ukusebenzisa. Bahlaba umxhwele ngobuncane besikrini esibukeka sisihle ngaphakathi. I-Edge LED ilinganiselwe uma kuziwa ekukhiqizeni umbala wemvelo. Ukwenza izinto zibe zimbi kakhulu, i-Edge LED akuyona inketho eshibhile ngoba ubuchwepheshe budinga imojula yokusabalalisa ye-LGP ezinikezele.

Ama-TV we-Edge LED
