Lub khw niaj hnub no muaj ntau yam khoom tshiab tuaj rau hauv cov khoom siv hauv tsev. Niaj hnub no, mus rau hauv lub khw, peb tuaj yeem pom ntau lub TVs, suav nrog cov uas tsim los siv cov thev naus laus zis niaj hnub no. Cov qauv kim heev yog LED TVs. Thiab ntau tus nyiam: LED TVs - nws yog dab tsi, thiab nws puas tsim nyog them nyiaj loj rau lawv?
Cov ntawv luv LED sawv rau "lub teeb emitting diode". Cov ntsiab lus no, txheej txheem hauv matrix, tsim lub hauv paus ntawm lub vijtsam TV thiab muab cov khoom siv hauv chav kawm no qhov sib txawv ntawm CCFL chav kawm kua siv lead ua cov ntxaij vab tshaus (siv cov teeb fluorescent), thiab tseem paub qhov txawv ntawm cov ntxaij vab tshaus cathode.
Dab tsi yog LED TVs hais txog cov duab zoo ntawm lub vijtsam? Kev siv cov LEDs muab TVs hauv chav kawm no muaj peev xwm ua kom pom lub teeb pom kev zoo ntawm txhua lub ntsiab ntawm lub vijtsam, tsis zoo li cov teeb txias cathode, uas teeb pom kev zoo.npo tag nrho. Txoj hauv kev no tso cai rau koj kom tau txais qhov tseem ceeb ntawm qhov sib txawv, uas ua rau cov duab pom tseeb li sai tau. Tsis tas li ntawd, LED TVs, uas nws cov thev naus laus zis tso cai rau siv ob qho tib si xim thiab tri-xim diodes, muab cov xim dav dua uas tsis muaj nrog lwm cov qauv TV.
Niaj hnub no, nyob rau hauv kev tsim khoom ntawm ntau yam khoom siv hauv tsev, cov khoom ua paug rau ib puag ncig feem ntau siv, uas tsis tso cai rau peb xav txog kev nyab xeeb yav tom ntej. Yog li ntawd, qee cov neeg siab zoo tab tom xav txog dab tsi LED TVs nyob rau hauv cov nqe lus ntawm ib puag ncig kev nyab xeeb, thiab yuav ua li cas lawv thiaj li pov tseg yav tom ntej. Thiab lawv tuaj yeem zoo siab: LED-systems tsis muaj mercury Cheebtsam; Tsis zoo li cov teeb ci, lawv haus 35-40% tsawg zog. Tsis tas li ntawd, kev puas tsuaj rau ib feem me me ntawm lub vijtsam TV tsis ua rau tsis muaj duab tiav. TV tuaj yeem saib ntxiv.
Thaum xaiv lub TV hauv lub khw, qee tus neeg mob siab rau cov ntawv luv ntxiv hauv lub npe - Direct lossis Edge. Thiab ntau tus neeg xav paub tias Direct class LED TVs yog dab tsi. Lo lus Direct hauv qhov no txhais tau hais tias cov LEDs sib npaug ntawm qhov screen, thiab lo lus Edge txhais tau hais tias lub diode matrix nyob ntawm cov npoo ntawm lub vijtsam thiab ua tiav los ntawm lub vaj huam sib luag diffusing. Direct TVs raug suav hais tias yog qhov zoo dua thiab kim dua, thaum Edge qauv nrov vim lawv cov tuab tsawg (qhov ntsuas notej zaum nyob ib ncig ntawm 4 cm).
Cov piv txwv tshiab ntawm LED thev naus laus zis muaj kev ua haujlwm nplua nuj. Kev nkag mus hauv Is Taws Nem, muaj peev xwm rub tawm thiab saib cov ntaub ntawv (suab paj nruag, clips, duab), rub tawm ntawm koj lub xov tooj lossis ntawm USB, cov duab hloov pauv mus rau 3D (los ntawm 2D), nkag mus rau Skype, saib 3D tsos yam tsis muaj tsom iav - qhov no yog LED TVs niaj hnub no.. Koj tsuas yog yuav tsum xaiv qhov loj ntawm lub vijtsam - qhov loj heev tsis haum rau txhua chav, vim tias lawv muab graininess hauv cov duab, uas ua rau nws nyuaj rau kev txaus siab rau cov cuab yeej tshiab. Txhua tus qauv ntawm LED TVs muaj qhov tsim kom zoo nkauj, uas tso cai rau lawv kom haum zoo rau txhua sab hauv thiab txawm tias dhau los ua nws qhov kho kom zoo nkauj.
