Ma rabtaa in aad ogaato waxa LED-telefishinada?

suuqa casriga ah waxay bixisaa noocyo kala duwan oo soo saarka cusub oo laga keeno oo duurka ku ah qalabka guriga. Maanta, in dukaanka socday, waxa aan arki karnaa daraasiin telefishinada, oo ay ku jiraan soo saaray iyadoo la isticmaalayo teknoolajiyada ugu casrisan. daydo halkii qaali yihiin telefishinada fasalka LED. Oo qaar badan oo ku mashquulsan yihiin: LED-telefishinada - waxa uu yahay, iyo haddii ay lagama maarmaan tahay in ay bixiyaan lacag badan iyaga?

Gaabiyay LED loola jeedaa «iftiin saaro diode», taas oo micnaheedu yahay "LED". walxahaasi waxaa lagu habeeyay shax sal ee shaashadda telefishanka iyo qalabka ku lifaaqan ee fasalka ka duwan CCFL screens LCD fasalka (isticmaalo laambad dhaadheer), iyo sidoo kale iyaga ka screens la cathodes qabow kala saaro.

Waa maxay-telefishinada LED marka la eego tayada sawirka shaashadda? Isticmaalka uu Kokes ku siinayaa telefishinada ee fasalka ay awoodaan in ay muujiyaan backlight ee element kasta soo bandhigay, sida ka soo horjeeda laambadood oo ay ku jiraan cathode qabow, oo iftiimin shaashadda si buuxda. Habka Tani waxay u ogolaaneysaa in la helo nooca aasaas cusub oo ka duwan ka dhigaya image sida cad. Intaa waxaa dheer, LED-telefishin, oo technology oo loo isticmaali karo sida hal midab ama uu Kokes ku saddex-midab, bixiyaan uugu a color ballaaran, kaas oo geli karin, waayo, tusaalayaal kale oo TV.

In waqtigeena, in soo saaridda ee xubno qalabka guryaha kala duwan waxaa loo isticmaalaa inta badan ku filan, nijaasayn deegaanka, taas oo aysan ka fiirsan badbaadada mustaqbalka. Sidaa darteed, qaar ka mid ah dadka macquul ah u malaynayso oo ku saabsan xaqiiqada ah in sida LED-telefishinada marka la eego nabadgelyada deegaanka, iyo sida ay lagu meeleyn karaa mustaqbalka. Oo iyana waxay ahaan kartaa war wanaagsan: LED-nidaamyada ha ka kooban qaybaha mercury, Si ka duwan nalalka incandescent, baabbi'in tamarta 35-40% ka yar. Intaa waxaa dheer, dhaawaca in qayb yar oo ka mid ah shaashadda TV-ga waxaa weeyaan maqnaanshaha dhamaystiran oo images. TV laga daawan karaa mustaqbalka.

Doorashada TV a dukaanka, fiiro gaar ah u qaar ka gaabiyey dheeraad ah horyaalka - Direct ama Edge. Oo qaar badan oo doonaya in ay ogaadaan waxa LED-telefishinada fasalka Direct. erayga Direct kiiskan ka dhigan tahay in uu Kokes waxaa isku diyaarin in shaashadda, iyo Edge erayga - in dagaal isugu diyaariyeen diode ah waxa uu ku yaalaa at geesaha shaashadda oo kaabaya baahinta guddi. Waxaa la rumeysan yahay class in Direct TV show ka wanaagsan oo ka qaalisan, oo lagu daydo Edge waa inay dhumucdiisuna waxay ugu yaraan mahad caan ah (waa tani waxay noqon kartaa ilaa 4 cm).

fasalka ugu dambeeyay ee nidaamyada technology LED leeyihiin shaqeynta balaaran. Helitaanka internetka, awood u leh inay kala soo bixi iyo u arkaan files (music, videos, photos), in lagala soo baxo telefoonka ama via ee isku xira USB, Converter image 3D (in 2D), Access Skype, daawashada filimaanta 3D aan koob - taasi waxa weeye waxa LED-telefishinada maanta. waxa keliya ee aad u baahan tahay inaad qaado size midig ee shaashadda - ma ku haboon yahay qolalka oo dhan waa mid aad u ballaaran, si ay u siineyso inay hadhuudh ee image ah, taas oo ka dhigaysa adag tahay inay ku raaxaystaan technology ugu dambeeyay ... All lagu daydo ee LED-telefishinada leeyihiin design soo jiidasho leh in u ogolaanaya inay si fiican u geli gudaha kasta, iyo xataa noqdaan ay farjiyadooda.
