Ama-TV namanje abaqapheli abayithathi isikhala esiningi - babonga kakhulu ubuchwepheshe obusha. Manje akuvamile lapho uhlala khona ungaboni umphumela wokuzilibazisa kusihlwa kusihlwa - i-LCD noma i- LED TV . Futhi uma ufuna nje ukuyithenga, cishe unombuzo mayelana ne-LCD noma i-LED - yini engcono? Ake sibone.
I-LCD ne-TV ye-LED: umehluko
Eqinisweni, umehluko phakathi kweLCD ne-LED ncane kakhulu. Zombili izinhlobo zihlobene nobuchwepheshe bamuva, obusebenzisa i-crystal matrix, equkethe amapulethi amabili. Phakathi kwazo zikhona amakristalu amanzi, okushintsha isikhundla sabo ngaphansi kwethonya lombane kagesi. Uma usebenzisa izihlungi ezikhethekile nezibani ezibuyiselwa emuva, izindawo ezikhanyayo nezomnyama zivela ebusweni bomthamo. Uma usebenzisa izihlungi zombala ngemuva kwe-matrix, isithombe sombala sivela esibukweni. Yeka uhlobo lokubuyiselwa emuva okusetshenzisiwe - yilokho kanye i-LCD ehlukile ku-LED.
Ababukeli be-LCD noma amathelevishini basebenzisa ukukhanyisa ngokukhanyisa ngezibani ezibandayo ze-cathode fluorescent ezifakwe emathinini e-cathode-ray. Zitholakala ku-matrix ngokuzungezile. Kulokhu, izibani ku-LCD ziqhubeka njalo, futhi ngoba uhlaka lwe-crystal lwakhizi alukwazi ukumisa umhlane ngokugcwele, kumbala omnyama esikrinini sibona imbopho emnyama.
Ababheki be-LED empeleni yi-subset ye-LCD, kodwa basebenzisa uhlobo oluhluke ngokuphelele lokukhanyisa - i-LED. Kulokhu, ama-LED atholakala ohlangothini noma ngokuqondile ngokukhululekile. Njengoba kungenzeka ukuwalawula, okungukuthi, ukunyamaza noma ukukhanyisa izindawo ezithile, ukungafani kwesithombe sezingqapheli ze-LED noma i-TV kusethi kudlulele kakhulu umahluko we-LCD. Ngaphezu kwalokho, umbala ongcono wokunikeza: ungabuka ama-movie akho nezintandokazi zakho ngaphandle kokuphazamiseka. Ngendlela, umbala omnyama uphenduka ngokujulile.
Umehluko obalulekile phakathi kweLCD ne-LED yiqiniso lokuthi ukusetshenziswa kwamandla okugcina akuphansi kakhulu. Ngenxa yokubuyiselwa kwe-LED, ukusetshenziswa kwamandla we-TV nokuqapha kuncishisiwe kuya cishe ku-40% kuqhathaniswa ne-LCD. Futhi isithombe salokhu asihlupheki!
Ama-TV e-LED kanye nokuqhathaniswa kwe-LCD ku-thickness. Ukusetshenziswa kwama-LED kuvumela ukukhiqizwa kwe-ultra-thin LED ababheki 2.5 cm obukhulu.
Kodwa inzuzo yamadivaysi e-LCD ihlala isakazeke futhi ishibhile uma kuqhathaniswa ne-LED.
