Qhov sib txawv ntawm Sab-Hom Thiab Ncaj Cia Hom LCD Backlight Tau qhov twg los

Sep 20, 2019

Cov backlight ntawm lcd zaub screen feem ntau yog coj, sab hom LED backlight thiab ncaj ncaj LED backlight. Dab tsi yog qhov sib txawv ntawm ob hom backlight no?

Sab-hom backlight yog backlight ua los ntawm teeb tsa cov kab teeb pom kev lossis teeb pom kev nyob rau sab ntawm daim phiaj qhia tshwj xeeb teeb pom kev zoo. Lub hauv paus ntsiab lus ntawm lub teeb taw qhia phaj yog tias qhov kev cuam tshuam ntawm cov teeb meem rhuav tshem lub teeb yog los ntawm cov teev faib rau hauv qab ntawm cov lus qhia teeb pom kev zoo acrylic board, thiab cov kab hluav taws xob yog sib npaug hloov mus rau saum npoo teeb pom kev zoo, thiab nws txoj haujlwm yog coj cov nplai kev coj ntawm lub teeb. Ua kev faib hluav taws xob ntawm cov teeb pom kev ntau dua kom cov duab ntxoov ntxoo ntawm qhov chaw tsis pom kev tsis tuaj yeem pom ntawm lub hauv ntej, thiab xyuas kom meej qhov sib thooj ntawm lub ci ntsa iab ntawm LCD npo. Kev siv hluav taws xob sab nraub qaum tuaj yeem ua tau nyias heev, tab sis kev siv lub teeb nrig ntawm lub backlight yog me dua, thiab daim nyias nyias siv tau yog, qhov siv tau tsawg dua. Lub hauv paus tseem ceeb ntawm thev naus laus zis yog kev tsim qauv thiab tsim tawm ntawm lub teeb taw qhia phaj, kev tswj hwm laser, haum rau cov ntsiab cai ntawm kev tsim khoom ntau. Nyob rau tam sim no, LCD cov khoom xav tau ntau dua kev coj ua lub teeb qhia lub phaj qauv, thiab cov kev txhaj tshuaj lub teeb coj qhia phaj yog ua txhua yam los ua qhov tseem ceeb ntawm txoj kev loj hlob ntawm cov teeb ci backlight. Sab coj LED backlight tuaj yeem hloov kho qhov kev txhim kho ntawm ultra-nyias kua siv lead ua kua zaub tshuaj ntsuam.

Ncaj qis LED backlight kev ua tau zoo dua, tsis xav tau lub teeb qhia lub teeb, yog kom muab cov teeb pom kev zoo thiab PCB rau hauv qab ntawm qhov chaw backlight, lub teeb los ntawm LED, dhau hauv qab ntawm qhov cuam tshuam, thiab tom qab ntawd los ntawm diffusion phaj, ua kom pom kev duab ci ci. Qhov tuab ntawm lub nraub qaum yog tsuas yog txiav txim siab los ntawm qhov siab ntawm cov kab noj hniav ntawm cov zaj duab xis thiab cov phaj tawg. Raws li kev xav, ntawm qhov ua tiav ntawm qhov ua tiav cov teeb tsa xav tau thiab qhov ci ci, qhov loj ntawm qhov siab ntawm qhov loj yog, qhov zoo dua qhov tsis sib xws ntawm lub teeb tawm los ntawm lub phaj tawg yog.
