Iimvumi zee-TV kunye nabagadi bamaphephancwadi abayithathi indawo enkulu - baye babonga kakhulu ubugcisa obutsha. Ngoku ayinqabile kwiyiphi indlu ongayiboni umxholo wobomi bokuphumla ngokuhlwa -LCD okanye i- TV ye-LED . Kwaye ukuba ufuna nje ukuyithenga, mhlawumbi unemibuzo malunga neLCD okanye i-LED - yintoni engcono? Makhe sibone.
I-LCD kunye ne-TV zeTV: umehluko
Enyanisweni, umahluko phakathi kweLCD kunye ne-LED ncinane. Zombini iintlobo zihambelana nezobuchwepheshe zanamhlanje, ezisebenzisa i-crystal matrix yamanzi, equlethwe ngamacwecwe amabini. Phakathi kwazo zikhona izikristali zamanzi, ziguqula indawo yazo phantsi kweempembelelo zamandla kagesi. Xa usebenzisa izihlomelo ezikhethekileyo kunye nezibane ezikhanyayo, indawo ezikhanyayo kunye nemnyama zibonakala kumgangatho we-matrix. Ukuba usebenzisa izihlungi zembala emva komthamo, umfanekiso wombala uvela kwisikrini. Luhlobo luni lokukhanyisa olusetyenziselwayo - yiloo nto iLCD ehluke ngayo kwi-LED.
Abahloli be-LCD okanye iithelevishini basebenzisa ukukhanya ngokukhanyisa kwezibane ezibandayo ze-cathode fluorescent ezifakwe kwiibhubhu ze-cathode-ray. Zifumaneka kwi-matrix ephezulu. Kule meko, izibane eziseLCD zihlala zihlala njalo, kwaye ngenxa yokuba uluhlu lwekristal lwamanzi alukwazi ukucima umkhanya ngokupheleleyo, kumbala omnyama wesikrini sibona umnyama omnyama.
Iindwendwe ze-LED ziyi-subset ye-LCD, kodwa zisebenzisa uhlobo oluhluke ngokupheleleyo lokukhanyisa-i-LED. Kule meko, ii-LED zifumaneka kwicala okanye ngokuthe ngqo kwizinto ezininzi. Ekubeni kunokwenzeka ukuyilawula, oko kukuthi, ukuba kumnyama okanye kukhanyise imimandla ethile, ukungafani komfanekiso wee-LED okanye iiseti zeTV zigqithise ngaphezu kwe-LCD. Ukongezelela, umbala ogqithiseleyo wokunikezela: unokujonga iifilimu zakho ezizithandayo kunye neenkqubo ngaphandle kokuphazamiseka. Ngendlela, umbala omnyama uphenduka kakhulu.
Ukwahluke kakhulu phakathi kwe-LCD kunye ne-LED yinto yokuba amandla okugqibela asetyenziswayo aphantsi. Ngenxa yokubuyiselwa kwe-LED, ukusetyenziswa kwamandla kwe-TV kunye nokubeka iliso kuncitshiswa phantse kwi-40% xa kuthelekiswa ne-LCD. Kwaye umfanekiso wale nto akahluphekanga!
Iimvumi ze-TV kunye ne-LCD zibukhulu. Ukusetyenziswa kwee-LED kuvumela ukuveliswa kwe-LED engapheliyo yokujonga i-2.5 cm ubukhulu.
Kodwa ukuxhamla kwamadivayisi e-LCD kuhlala kudla kunye nokunciphisa xa kuthelekiswa ne-LED.
