Yintoni na LED-TV ingcono ukuthenga" Ukuba ufunda uphononongo kumthengi kwi Internet, siyakwazi ukubona ukuba imveliso imifuziselo ithandwayo iinkampani zilandelayo: i LG, Samsung, Toshiba, Philips, Sony, Supra kunye Akai. Ukukhetha zezakho.

LCD TV

Yintoni na le LCD screen? Le matrix equka ngamachaphaza. Ezi zinto (amachaphaza) zibizwa ngokuba pixels. A pixel - oku sub-pixels ngemibala ebomvu, eluhlaza kunye nezuba. izinto ngaphakathi ziikristale ulwelo, ukutshintsha lungiselelo yalo entsimini yombane. Kuba matrix are ilayithi. Xa uhambisa ziikristale nokuba ibhloko okanye ukudlulisela ukukhanya kwezi izibane. Isibane enamandla kakhulu, kokukhona kungcono umbala, kodwa amandla, ngokulandelelanayo, ngasentla. Nomabonakude ezinjalo umtsalane kubathengi ngentengiso efikelelekayo. Ezi neengxaki kuquka ukubukela engile elimxinwa. Kodwa kukho pluses: ukukhanya nokulungisa amaxabiso ahlukeneyo ixhomekeka kuhlobo TV. Kwezi zihlandlo, kuyimfuneko ukunikela ingqalelo xa uthenga i LCD.

Kwiseli eludongeni isale sisincoko okhethekileyo, yaye wadibana kwimitha, ngokuxhomekeke ukwakhiwa umaleko, siya ukufumana umbala oyifunayo. Ukuba ombane lingaphezulu, iseli ovuthayo eliqaqambileyo. Ngokuxuba imibala zaseprayimari efunyenwe ezahlukeneyo abangasekhoyo. Bomfanekiso kwikhusi ezikhandelwa yi lomnqongo elektroniki, lo oscillator ombane kulawulwa.
