coj backlight Brightness txhim khu zaj duab xis (BEF) Prism daim ntawv qauv thiab lub hauv paus ntsiab lus

Lub teeb intensifiers yog siv los ua kom lub teeb ci ntawm lub vijtsam thiab muab faib ua ob hom: refractive light intensifiers thiab tag nrho cov teeb pom kev zoo intensifiers. Hom refractive yog tsim los ntawm kev hloov cov yas resin zaj duab xis nyob rau hauv siab.
Lub kaum sab xis ntawm cov yeeb yaj kiab refractive yog 90 degrees, thiab cov khoom siv sab saum toj thiab hauv qab yog siv orthogonally nrog ib leeg. Txhawm rau tsim cov nyhuv declination, ib qho qis diffusion zaj duab xis yog teem rau hauv qab ntawm zaj duab xis, thiab ntxiv rau, ib qho kev taw qhia lub teeb thiab lub teeb pom kev zoo; ib tug dawb dot qauv kuj luam nyob rau hauv lub teeb qhia. Cov nyhuv tawg ntawm cov qauv yog siv los tsim cov kab hluav taws xob tawm, thiab tom qab ntawd qhov cuam tshuam thiab cuam tshuam ntawm cov ntawv qis diffusion yog siv los hloov cov kab hluav taws xob tawm, thiab ntxiv los ntawm cov ntawv refracting lub teeb intensifier, cov nqaj yog coj mus rau ib txwm. tso saib. Nyob rau hauv txoj kev no, lub Cheebtsam ntawm lub teeb nto yog concentrated nyob rau hauv ib txwm kev taw qhia los ntawm ob lub teeb intensifiers uas yog orthogonal rau ib leeg, yog li ua kom lub brightness. Nrog rau cov txheej txheem no, kev siv lub teeb raug txo vim qhov muaj qhov cuam tshuam tsis zoo thiab lub teeb nqus dej poob.
Tag nrho cov kev xav ntawm hom intensifier yog tsim los ntawm kev siv UV-hardening hom resin ntawm polyester zaj duab xis ntawv thiab sau nws mus rau hauv cov duab ntawm cov ntawv intensifier.
Tag nrho cov nyhuv reflection ua rau nws cov kev taw qhia ib txwm tua rau hauv cov zaub. Piv nrog rau refractive hom intensifiers, tsawg dua qhov chaw thiab cov ntaub ntawv siv, thiab vim hais tias tag nrho cov kev xav ntawm lub teeb yog siv, reflection poob thiab lub teeb absorption poob yog me me, ua rau lub teeb siv ntau dua.
LED backlight reflective diaphragm feem ntau yog teem rau hauv qab ntawm lub teeb qhia thiab yog siv los ua kom lub teeb pom kev ntawm sab hauv ntawm lub teeb qhia kom txo qhov attenuation ntawm lub teeb mus txawv tebchaws; thaum lub diaphragm reflective nyob ib ncig ntawm lub teeb yog siv los tshem tawm lub teeb nrog high efficiency.
