Ingabe ufuna ukwazi ukuthi yini LED-TV?

Izinto zesimanje emakethe linikeza ezihlukahlukene imikhiqizo emisha amazwe emkhakheni ekhaya Imishini. Namuhla, uya esitolo, singabona eziningi ama-TV, kuhlanganise ekhishwe usebenzisa ubuchwepheshe esimanjemanje kakhulu. onobuhle Kunalokho ezibizayo kukhona ekilasini LED TV. Futhi abaningi banesithakazelo: LED-TV - kuyini, futhi kungakhathaliseki ukuthi kubalulekile ukuba akhokhe imali enkulu ngabo?

Isifinyezo LED kusho «ukukhanya likhipha diode», okuyinto uhumusha njengoba "LED". Lezi zici ahlelwe matrix yisisekelo nasezenzakalweni namadivayisi enamathiselwe kuleli kilasi ngokungafani CCFL LCD izikrini ekilasini (wasebenzisa isibani Fluorescent), kanye kwehlukaniswe izikrini cathodes ezibandayo nge.

Kuyini LED-TV ngokuya ikhwalithi yesithombe esikrinini? Ukusetshenziswa LED unikeza TV kuleli kilasi bayakwazi ukubonisa backlight ngayinye ukubonisa isici, njengoba kuqhathaniswa izibani kuhlanganise cathode abandayo, okuyinto ikhanyisa ngokuphelele esibukweni. Le ndlela ivumela ukuthola uhlobo ngokuyinhloko entsha Ngokuphambene eyenza isithombe njengoba kucacile. Ngaphezu kwalokho, LED-TV, okuyinto ubuchwepheshe ingasetshenziswa njengendlela umbala owodwa noma Tri-umbala LED, anikele ebanzi yombala, okuyinto ezingafinyeleleki ngoba kweminye imihlobo TV.

Esikhathini sethu, ekwenzeni ezihlukahlukene zasendlini izakhi ezisetshenziswa njalo ngokwanele, bangcolise indawo ezungezile, okuyinto akacabangi ukuphepha esizayo. Ngakho-ke, abanye abantu abanengqondo cabanga yokuthi enjalo LED-TV ngokuya zokuphepha kwemvelo, futhi bangakwazi ilahlwe Ngokuzayo kanjani. Futhi kungaba izindaba ezinhle: LED-izinhlelo zingenalo izingxenye mercury; Ngokungafani incandescent ama, kudle amandla 35-40% ngaphansi. Ngaphezu kwalokho, ukulimala ingxenye encane yesikrini TV akuhileli sokungabi nhlobo izithombe. TV ingabukwa esikhathini esizayo.

Ukukhetha TV esitolo, banake ezinye izifinyezo ezengeziwe isihloko - Direct noma Umphetho. Futhi abaningi bafuna ukwazi ukuthi yini LED-TV ekilasini okuqondile. izwi ngqo kulesi simo kusho ukuthi LED kuthiwa nombala ahlelwe isikrini, bese izwi Edge - ukuthi afanayo diode itholakala emaphethelweni kwesikrini futhi kulekelelwa diffusing panel. Kukholakala ukuthi ikilasi Direct we-TV kangcono futhi ezibiza kakhulu, futhi Edge model sibonga eyayithandwa Uhlonze lwalo ubuncane (lesi sibalo kungaba emhlabeni 4 cm).

Ikilasi yakamuva LED Ubuchwepheshe amaphethini nomsebenzi ebanzi. Ukutholakala kwe-Internet, ikhono ukuze ulayishe bese ubuka amafayela (umculo, amavidiyo, izithombe), ukulanda kusuka efonini noma nge isixhumi se-USB, isithombe Converter ku-3D (2D), Finyelela Skype, ukubukela amabhayisikobho 3D ngaphandle izibuko - yilokho LED-TV namuhla. Udinga nje ukukhetha ubukhulu kwesokudla kwesikrini - asifanele wonke amagumbi makhulu kakhulu, ngakho sipha kokusanhlamvu isithombe, okwenza ukuthi kube nzima ukujabulela ubuchwepheshe bamuva ... Wonke amamodeli we-LED-TV babe-design ekhangayo evumela ukuthi ukuba uvumelane ngokuphelele kunoma iyiphi elingaphakathi, ngisho babe lwaluthintwa yayo.
