I-LED Backlight ibhekisa ekusetshenzisweni kwama-LED (ukukhanya okukhanyisa ama-diode) njengomthombo wasemuva wesibonisi se-liquid crystal, ngenkathi isibonisi se-LED backlight singumthombo okhanyayo wesibuko se-ccfl esikhawini esivela ku-CCFL Chlfl light tube (okufana namalambu we-fluorescent ) Ku-LED (ukukhanya okukhipha i-diode). Umgomo wokucabanga wekristalu ewuketshezi ungaqondwa nje njengeqiniso lokuthi i-voltage yangaphandle esetshenziselwe ukungcola kwama-molecule awuketshezi avinjelwe ukukhanya okukhishwe yisango njengesango elinjengesango imibala ukwakha isithombe.

I-Edge-Lit LED Backlight

I-Edge-Lit LED Backlight ukuhlela ukuthi i-LED ifela engxenyeni yesikrini se-LCD, bese ifanelana ne-LIDE PLATE Plate, ukuze kuthathwe i-LED backlight module ukukhanya, kukhishwe onqenqemeni lwesikrini indawo ephakathi yesikrini ngepuleti yomhlahlandlela wokukhanya. , Ukuze inani eliphelele le-backlight, elivumela isikrini se-LCD ukukhombisa izithombe.

Ukuthuthukiswa kwe-Edge-Lit LED Backlight

Ngokuthuthuka okuqhubekayo kobuchwepheshe, i-back-side i-backlight izokhula kusuka ku-LED eyodwa ezinhlangothini ezingenhla nezingaphansi ku-LED eyodwa yokugcina eyodwa. Ngokuvamile, i-TV eyodwa ye-backlit eyodwa kuzo zombili izinhlangothi ezingama-32 "ezingabonakala emakethe zisebenzisa ama-LED angaba ngu-120 kuya kwayi-150. Uma i-TV backlight iguqulwe yaba ngu-80-100 ( Okungagcina kuncishiswe inani lama-LEDs kuncike kubuchwepheshe bomkhiqizo). Uma ubuchwepheshe bufaniswa, ikusasa elibonakalayo, i-LED eyodwa izoguqulwa kusuka ohlangothini olude (phezulu noma phansi) kuya kufushane uhlangothi (kwesobunxele noma kwesokudla). Lolu hlobo loshintsho luzosebenzisa inombolo encane ye-LED yezinhlayiya.

Ukunwetshwa kwempilo

Ukunciphisa ukusetshenziswa kwama-LED akugcini ngokuba nomthelela omuhle ngokulawulwa kwezindleko, kepha futhi sibona eminye imiphumela emihle kumamojula. Isibonelo, izinga lokushisa lemodyuli lizoncishiswa ngenxa yokusetshenziswa okuncane kwama-LED. Uma sithatha le ngenhla 32 "LCDTV njengesibonelo, ukusetshenziswa okuncane kwenombolo yama-LED kunganciphisa izinga lokushisa lemodyuli cishe nge-10% -15%. Yize singakwazi ukubala ngokwesayensi ukuthi le nombolo ingandisa isikhathi sokuphila kwezitho ze-elekthronikhi, noma Ngisho nama-TV, kusuka ekukhulumeni ngokujwayelekile, ukuncishiswa kwezinga lokushisa kumele kube nomthelela omuhle empilweni yezingxenye ze-elekthronikhi. Lolu sizo lusobala kakhulu endaweni enkulu ye-LED TV, ngoba kukhona ama-LED ambalwa akuvamile ukusetshenziswa.

I-angle ebanzi yokubuka

Ngaphezu kwalokho, ukusetshenziswa kwezixazululo zefilimu eziphakeme kakhulu zokuthuthuka kwe-Enhancion Ngoba umgomo wobuchwepheshe wefilimu yokuqhakambisa ukugqama okuphezulu ukudlulisa ukukhanya okukhalweni kwimodyuli yasemuva ukujikeleza nokukhombisa kuze kuboniswe ingilazi. Imodyuli e-backlight esebenzisa ifilimu lokuqhakambisa ukuthuthuka lithuthukisa ukukhanya cishe ngama-30% ngokuqhathaniswa nemodyuli engasebenzisi ifilimu ebonakalayo. Njengoba ifilimu yokuthuthuka kokukhanya okuphezulu ihlukile ku-General Prism Film, akudingi ukunikela nge-angle yokubuka ukukhulisa ukugqama, ngakho-ke ifilimu eliphakeme eliphakeme lokuqhakaza lithandwa kakhulu ngabakhiqizi be-TV nabakwamanye amazwe. Ngendawo eyandayo ye-LCDTVS, abathengi sebeqalile ukuba nezimfuneko ezithile zokubuka ama-engeli. I-47 "LCD TV enamasentimitha angaphezu kuka-10,000 ibekwa phakathi kwegumbi lokuhlala. Kuliqiniso, inhloko yekhaya inethemba lokuthi izivakashi zihlala kunoma iyiphi i-angle zingajabulela ikhwalithi efanayo yesikrini se-TV.

Ukulondolozwa kwamandla namandla okulondolozwa kwamandla

Kuyiqiniso, umphakathi ungathola ngokuqondile ngokuqondile izinzuzo ze-Edge-Lit Led Backlights, okuwukuncishiswa kokusetshenziswa kwamandla okuphelele kwe-TV. Ama-TV ajwayelekile ajwayelekile angama-32 "ahola emuva kwe-TV, izinga lamanje ngokuvamile lisebenzisa cishe ama-80w. Leli zinga lilingana neleveli yesithathu kumazinga wakamuva kazwelonke wokusebenza kwamandla kazwelonke.

Uma abakhiqizi bafuna ukuthuthukisa amazinga wokusetshenziswa kwamandla we-TV, kunezisombululo eziningi ezihambisanayo, kepha zisebenzisa i-High-Performance Excyness Fing. Uma kuhlanganiswe nefilimu yokuthuthuka kokukhanya okuphezulu, ukusetshenziswa kwamandla kungancishiswa cishe ngama-20% -30% ngenkathi kugcinwa izinga elifanayo lokukhanya (ukusebenza kokugcina kuncike ebukhweni bemikhiqizo ngayinye). Ukusuka ekubalweni kwamanani, ukusetshenziswa kwamandla kwe-TV kungathuthukiswa kusuka kuma-80w kuya kwangama-60w ngokusebenzisa i-high-perch access ukuthuthukiswa kwefilimu yokuthuthuka okuphezulu. Ukuthuthukiswa kokusetshenziswa kwamandla kungavumeli abakhiqizi ukubambisana ngamandla nenqubomgomo kazwelonke yokuvikela imvelo, kepha futhi isiza abathengi ngezikweletu ezihlobene nogesi.

Ukusuka ekuhlaziyweni kwezobuchwepheshe okungenhla, siyabona ukuthi ukwakheka kwe-backight elikhanyiswe yinzuzo kubakhiqizi nabathengi. Esikhathini esizayo esiseduze, ama-LEDs angashadile akhanyiswe ngonqenqema kufanele abe yindawo yokugcina ye-LED Backlights.
