Masiku ano, Ma TV a LED akhala chisankho chodziwika bwino kwa ogula omwe akufunafuna chithunzithunzi chapamwamba komanso kugwiritsa ntchito mphamvu. Komabe, nthawi zambiri pamakhala chisokonezo ponena za mawu akuti 'LED TV.' Anthu ambiri amaganiza kuti amatanthauza mtundu wina waukadaulo wapawayilesi, koma kunena zoona, ma TV a LED ndi kagulu kakang'ono ka ma TV a LCD omwe amagwiritsa ntchito ma light-emitting diode (LEDs) ngati nyali zawo zakumbuyo. M'nkhaniyi, tiwona zomwe ma TV a LED ali, momwe amagwirira ntchito, mitundu yawo, mawonekedwe ake, ndi zomwe zimawapangitsa kukhala abwino kwambiri kwa ogula amakono.
Kumvetsetsa LED TV
Kodi TV ya LED ndi chiyani?
Pakatikati pake, TV ya LED imangokhala TV ya LCD yokhala ndi kuyatsa kwa LED . Ukadaulo womwe umagwiritsidwa ntchito pazenera lokha, mawonekedwe amadzimadzi amadzimadzi (LCD), ndi ofanana ndi akale akale, koma makina owunikiranso asinthidwa kuchokera ku CCFL (Cold Cathode Fluorescent Lamps) kupita ku ma LED . Kusinthaku kumapangitsa kuwala, kusiyanitsa, ndi kuwongolera mphamvu kwinaku kumapangitsa kuti pakhale mapangidwe owonda komanso opepuka.
Kodi TV ya LED Imayimira Chiyani?
LED imayimira Light Emitting Diode . Mosiyana ndi ma TV akale a CCFL-backlit LCD, omwe amagwiritsa ntchito nyali za fulorosenti kuti ziwunikire pazenera, ma TV a LED amagwiritsa ntchito ma diode ang'onoang'ono kuti apange kuwala. Ma diode a LED mu ma TV a LED ndi opatsa mphamvu, okhalitsa, ndipo amatha kutulutsa kuwala kopambana poyerekeza ndi ma CCFL. Kusintha kumeneku kwadzetsa chithunzithunzi chabwinoko, chokhala ndi zakuda zozama komanso mitundu yowoneka bwino.
Kodi Kuunikira kwa LED Kumagwira Ntchito Motani?
Kuunikira kwa LED ndi njira yomwe ma LED amagwiritsidwa ntchito kuyatsa chophimba cha LCD. Ngakhale makhiristo amadzimadzi samatulutsa kuwala paokha, amawongolera kuwala kopangidwa ndi ma LED kuti apange zithunzi. M'malo mwake, ma LED amapereka kuwala kofunikira kuti makhiristo amadzimadzi aziwongolera. Kuwongolera kwa kuwalaku kumathandizira kuwongolera bwino kwazithunzi, kupangitsa ma TV a LED kukhala njira yabwino kwa iwo omwe akufuna magwiridwe antchito apamwamba.
Mitundu ya Kuunikira kwa LED ndi Zotsatira Zake
Ma TV a LED sanapangidwe mofanana. Pali mitundu ingapo yaukadaulo wowunikira kumbuyo kwa LED, iliyonse ili ndi zabwino zake. Kumvetsetsa kusiyana kumeneku kungakuthandizeni kusankha mwanzeru mukagula TV yatsopano.
Edge-Lit LED Technology
Ma TV aku Edge-light LED ali ndi ma LED omwe amayikidwa m'mphepete mwa chinsalu. Kuwalako kumafalikira pazenera lonse pogwiritsa ntchito kalozera wowunikira. Mapangidwe awa amalola ma TV ocheperako, kuwapangitsa kukhala abwino kwamkati mwamakono, ocheperako. Komabe, kuyatsa koyang'ana m'mphepete kumatha kubweretsa kuwala kosagwirizana, makamaka pazithunzi zakuda, popeza kuwalako kumachokera m'mphepete.
