Loj-screen LCD backlight thiab dav dav teeb pom kev zoo txhawb kev loj hlob sai

Hauv xyoo 2015 thiab 2016, cov nyiaj tau los ntawm kev lag luam teeb pom kev lag luam tau tswj hwm tus lej ib tus lej loj hlob, tab sis xyoo 2017 kev lag luam yuav tsum txhawb nqa cov nyiaj tau los ntawm LED kom ncav cuag ob tus lej.

iSuppli kwv yees tias tag nrho LED kev lag luam turnover nyob rau hauv 2017 yuav loj hlob los ntawm kwv yees li 13.7%, thiab cov compound txhua xyoo kev loj hlob tus nqi rau 2016-2012 yuav yog kwv yees li 14.6%, thiab nws yuav ncav cuag 12.3 billion US dollars los ntawm 2012. Nyob rau hauv 2015 thiab 2016, lub ntiaj teb no LED kev lag luam turnover tsuas yog nce 2.1% thiab 8.7% feem.

Cov lej no suav nrog tag nrho cov khoom siv saum npoo av (SMD) thiab los ntawm lub qhov pob LED teeb thiab alphanumeric zaub LEDs-xws li cov qauv ci ntsa iab, siab ci (HB) thiab ultra siab brightness (UHB) LEDs.

Ib feem ntawm qhov kev xav tau loj hlob tau hais los saum toj no yuav los ntawm ultra-high brightness thiab high-brightness LEDs siv nyob rau hauv daim ntawv thov teeb pom kev zoo.Los ntawm 2012, ultra-high-brightness LEDs yuav suav txog li 31% ntawm tag nrho LED turnover, ntau dua 4% hauv 2015.

Tus neeg tsav tsheb tseem ceeb ntawm kev lag luam loj hlob

"Nyob rau theem tshiab LED txoj kev loj hlob, kev ua lag luam tseem muaj kev thov kom muaj zog-lub xeev teeb pom kev zoo rau khawm backlights thiab cov khoom siv mobile.Qhov no yog qhov tseem ceeb tshaj plaws txhawb kev loj hlob ntawm LED kev lag luam, "said Dr. Jagdish Rebello, tus thawj coj thiab tus thawj kws tshuaj ntsuam ntawm iSuppli."Lub tsheb teeb pom kev zoo sab hauv, nrog rau cov teeb pom kev zoo ntawm lub vijtsam loj LCDs rau TVs thiab laptops, cov kev lag luam tawm tshiab no tseem yuav txhawb kev loj hlob ntawm LED kev lag luam.Tsis tas li ntawd, kev txhim kho txuas ntxiv ntawm cov khoom siv hluav taws xob teeb pom kev zoo tseem yuav ua rau LEDs nrhiav cov ntawv thov tshiab hauv cov teeb pom kev zoo nkauj thiab vaj tsev teeb pom kev lag luam.Qhov chaw ntawm martial arts. "

LCD backlight tseem yog daim ntawv thov tseem ceeb ntawm LED

Tsis ntev los no, lub vijtsam LCD me me thiab lub xov tooj ntawm tes khawm backlights tseem yog qhov loj tshaj plaws ib daim ntawv thov kev lag luam rau LEDs.Hauv xyoo 2017, cov ntawv thov no yuav suav txog ntau dua 25% ntawm tag nrho LED kev lag luam turnover.

LED lub hom phiaj loj dua LCD backlights

Pib xyoo 2017, lub teeb rov qab ntawm LCDs loj dua xws li phau ntawv sau thiab cov LCD TVs intuitive tau dhau los ua cov ntawv thov tseem ceeb ntawm LEDs.

Tus nqi ntawm LCD backlight module (BLU) tseem ntau dua li cov tsoos CCFL BLU, tab sis tus nqi ntawm ob yog sai sai.Thiab LED BLU muaj qhov zoo ntawm kev ua tau zoo, xws li qhov sib txawv siab dua, lub sijhawm tig nrawm dua, qhov dav xim gamut, thiab qhov tsis muaj mercury kuj pab nws tau txais yuav hauv LCDs.

Qee tus neeg muag khoom LED, BLU manufacturers, LCD vaj huam sib luag manufacturers thiab TV / zaub OEM manufacturers tam sim no tau pib siv LEDs li backlight ntawm loj-screen LCDs.Loj-screen LCDs siv LED BLU kuj tau pib ua lag luam xa khoom.

LED: Lub neej yav tom ntej ntawm kev teeb pom kev zoo

Txoj kev loj hlob ntawm high-flux LEDs nrog ib tug luminous efficiency ntawm ntau tshaj 100 lumens / watt thiab tshwm sim ntawm lub tshiab tsim tau enabled LEDs ua hauj lwm nrog alternating tam sim no yam tsis xav tau rau inverters, yog li thawb LEDs los ze zog mus rau lub mainstream kev lag luam teeb pom kev zoo.

LEDs tau siv ntau yam kev siv teeb pom kev zoo sab hauv tsev thiab sab nraum zoov, thiab tab tom pib tsom mus rau kev siv teeb pom kev zoo xws li teeb nyem, teeb vaj, thiab teeb pom kev.Cov kev siv no yog qhib kev lag luam rau LED teeb pom kev zoo hauv kev lag luam hauv tsev thiab teeb pom kev lag luam.

Tsis tas li ntawd, lub ntiaj teb no tau tshaj tawm txoj cai txwv tsis pub siv cov teeb ci incandescent thiab txhawb kom siv cov khoom siv hluav taws xob txuag hluav taws xob.Nyob rau hauv lub neej yav tom ntej, compact fluorescent tubes (CFL) yuav tau txais txiaj ntsig los ntawm cov kev cai lij choj uas txwv tsis pub siv cov roj teeb incandescent.

Tab sis nyob rau hauv lub sij hawm ntev, qhov zoo ntawm cov teeb pom kev zoo-xeev yuav cuam tshuam tus nqi sib txawv ntawm LEDs thiab CFLs.Thiab raws li kev ua haujlwm ntawm LED txuas ntxiv txhim kho, tus nqi sib txawv yuav raug txo ntxiv.

iSuppli kwv yees tias xyoo 2020 LED qhov muag teev yuav pib siv rau hauv cov teeb pom kev zoo rau thaj chaw thiab teeb pom kev lag luam.
