Hauv ntau yam khoom lag luam, qhov ci ntsa iab yog qhov tseem ceeb rau kev ua kom pom tseeb cov duab pom, tshwj xeeb tshaj yog nyob rau hauv qhov chaw ci ntsa iab. Qhov ci ntsa iab tsis txaus nyob rau hauv cov lus qhia ncaj qha ua rau tsis pom kev, cuam tshuam rau cov neeg siv kev paub.
Cov txheej txheem ib txwm siv rau kev txhim kho qhov ci ntsa iab suav nrog kev nce LED nti ntom nti, tab sis txoj hauv kev no muaj qhov tsis zoo hauv qab no:
○ Qhov chaw lub cev:LED vaj huam sib luag cheeb tsam yuav saturated, tawm hauv tsis muaj chaw rau ntxiv qhov chaw.
○ Kev siv hluav taws xob tsis zoo:Kev siv hluav taws xob tag nrho nce ntxiv, ua rau lub zog ntawm cov khoom siv hluav taws xob thiab roj teeb lub neej.
○ Kub Dissipation Failure:Sustained siab kub ceev lub aging ntawm optical films.
Due to the limitations of increasing LED chip density, optical brightness enhancement film technology has become one of the effective ways to improve brightness, with DBEF film showing particularly outstanding performance.
Hais txog DBEF
DBEF, luv luv rau Brightness Enhancement Zaj duab xis, yog ntau- txheej txheej reflective polarizing zaj duab xis tsim los ntawm cov kws kho qhov muag.
Tsis zoo li cov yeeb yaj kiab ua kom pom kev ci ntsa iab zoo tib yam (xws li BEF), DBEF optical zaj duab xis tsom rau kev ua kom zoo thiab rov ua kom lub teeb pom kev zoo. Nyob rau hauv lub backlight modules ntawm coj mus muag zaub, DBEF feem ntau yog muab tso rau ntawm lub diffuser thiab polarizer, ua raws li ib tug connector ntawm ob. Los ntawm nws cov txheej txheem ntau- txheej txheej, nws hloov lub teeb khib nyiab rau hauv cov zis siv tau, txhim kho qhov ci ntsa iab.
Piv rau BEF (Brightness Enhancement Film), uas feem ntau refracts thiab tsom lub teeb los ntawm cov qauv prism, ib daim ntawv tuaj yeem txhim kho qhov ci ntawm 40% -60%, nrog cov txiaj ntsig zoo dua thaum ob nplooj ntawv siv ua ke.
Txawm li cas los xij, DBEF mus rau ib kauj ruam ntxiv, sib txuas cov thev naus laus zis polarization, ua rau nws tsim nyog rau kev lag luam scenarios nrog cov kev xav tau siab dua rau kev ci ntsa iab thiab kev siv hluav taws xob. DBEF ua kom pom tseeb ntawm cov duab hauv qhov chaw muaj teeb pom kev zoo yam tsis tau nce nqi kho vajtse.
DBEF ua haujlwm li cas?
Lub hauv paus ntawm DBEF yog nyob rau hauv nws tuav lub teeb polarized. Nyob rau hauv cov txheej txheem LCD backlight systems, lub teeb emitted los ntawm lub teeb qhov chaw yog unpolarized. Thaum nws dhau los ntawm qhov qis polarizer, kwv yees li ib nrab ntawm lub teeb (P2 polarized lub teeb) yog absorbed thiab nkim, ua rau tsis tshua muaj efficiency.
DBEF polarizer cleverly daws qhov teeb meem no: nws tso cai rau ib hom ntawm polarized lub teeb (P1) hla ncaj qha thaum xav txog P2 lub teeb rov qab mus rau hauv lub backlight. Qhov teeb pom kev zoo no tau rov ua dua thiab hloov dua siab tshiab nyob rau hauv kab noj hniav backlight, nws thiaj li ib nrab hloov rov qab rau hauv P1 lub teeb rau rov siv dua. Qhov kev rov ua dua tshiab no tuaj yeem txhim kho luminous efficiency los ntawm kwv yees li 1.8 mus rau 2 zaug.
Tsis tas li ntawd, DBEF tau nruab nrog qhov sib txawv ntawm qhov chaw tsim, uas tsis yog tsuas yog txhim kho qhov ci tab sis kuj txhim kho qhov pom kev sib xws, zam qhov teeb pom kev lossis qhov tsis sib xws.
Qhov no yog qhov tshwj xeeb tshaj yog muaj txiaj ntsig hauv kev lag luam vim nws tuaj yeem ua ke nrog lwm cov yeeb yaj kiab kho qhov muag xws li BEF lossis ESR (Enhanced Reflective Film) los tsim cov kev daws teeb meem.
Hom Hom DBEF
Nyob ntawm daim ntawv thov scenario, DBEF muaj ntau qhov sib txawv los hloov mus rau ntau yam kev xav tau ntawm cov khoom lag luam:
①DBEF-M: Nto-coated diffusion txheej tiv thaiv tsis xav tau kev sib cuag nrog lwm cov khoom siv kho qhov muag. Thaum ua ke nrog BEF, nws pab txo cov qauv moiré (kev cuam tshuam kev cuam tshuam), haum rau sab hauv tsev thiab sab nraum zoov cov duab uas yuav tsum tau muaj cov duab zoo.
②DBEF-D:Muab ob npaug rau-ib daim ntawv sib txuas sib txuas, txhim kho cov khoom siv dag zog thiab thermal stability ntawm zaj duab xis, haum rau siab - qhov kub thiab txias ib puag ncig, xws li cov khoom lag luam tsheb.
③DBEF-D200:Zoo sib xws hauv cov qauv rau DBEF-D, tab sis tsuas yog 200μm tuab, nyias thiab sib dua, ua kom yooj yim rau kev sib koom ua ke hauv cov khoom siv compact yam tsis muaj kev cuam tshuam kev ua haujlwm.

Txoj hauj lwm ntawm DBEF nyob rau hauv lub backlight qauv ntawm coj mus muag zaub:
Qhov zoo ntawm DBEF rau Kev Lag Luam Qhia
Rau cov chaw tsim khoom lag luam, qhov kev nyiam tshaj plaws ntawm DBEF nyob hauv nws "plug{0}}thiab-play" xwm. Tsis muaj kev hloov pauv cov qauv uas twb muaj lawm lossis nce kev siv hluav taws xob, tsuas yog ntxiv DBEF zaj duab xis tuaj yeem ua tau raws li cov neeg siv khoom xav tau rau siab - cov ntxaij vab tshaus ci ntsa iab.
Qhov no yog qhov txiaj ntsig tseem ceeb hauv kev ua lag luam uas muaj kev sib tw heev: piv txwv li, POS cov cav tov yuav tsum muaj kev nyeem tau nyob rau hauv lub hnub ncaj qha. DBEF pab txhawb kev ci ntsa iab los ntawm cov qauv qib thaum ua kom lub zog siv tau ruaj khov, tiv thaiv kev kub dhau.
Los ntawm kev xav txog kev siv hluav taws xob, DBEF txo cov teeb pom kev zoo, txo qis cov nqi khiav lag luam. Xav txog yog tias lub vijtsam loj ua lag luam tso siab rau ntau LEDs rau qhov ci; tsis tsuas yog thawj zaug peev yuav siab, tab sis nws tseem yuav nce nqi hluav taws xob thiab kev saib xyuas lub nra.
DBEF hla cov teeb meem no los ntawm kev kho qhov muag kho qhov muag, muab kev daws teeb meem ruaj khov. Nyob rau tib lub sijhawm, nws qhov pom kev zoo ua kom muaj kev sib txawv ntawm - cov duab dawb, ua rau nws tsim nyog rau kev tshaj lij xws li kev kho mob thiab kev saib xyuas kev lag luam.
Kev ceev faj rau kev siv DBEF
Thaum DBEF optical zaj duab xis muaj zog, kev teeb tsa kom raug thiab ntsuas qhov tseem ceeb yog qhov tseem ceeb. Lub ntsiab lus tseem ceeb yog tias qhov kis tau tus mob ntawm DBEF yuav tsum ua tib zoo sib xws thiab ua raws li cov kab sib txuas ntawm cov polarizer nram qab. Qhov no yuav tsum tau kuaj xyuas los ntawm kev kuaj ua ntej - teeb pom kev zoo (FOG calibration); txwv tsis pub, qhov ci poob lossis xim cam tuaj yeem tshwm sim.
Thaum disassembling lub backlight module, xyuam xim rau txoj hauj lwm ntawm DBEF zaj duab xis. Nws feem ntau yog nyob saum txheej diffuser rau kev txheeb xyuas yooj yim.
Tsis tas li ntawd, thaum kuaj backlight brightness ib leeg, tus nqi yuav qis me ntsis tom qab ntxiv DBEF. Qhov tseeb qhov ci yuav tsum tau sim ua ke nrog lub module.
Cov neeg tsim khoom raug qhia kom ua qhov kev sim dav dav ntawm optoelectronic thaum lub sij hawm tus qauv tsim kom ntseeg tau tias muaj kev sib haum xeeb.
Xaus
Nyob rau hauv ib lub sijhawm uas cov khoom lag luam siv zog ua kom pom kev ci ntsa iab ntau dua thiab qis dua kev siv hluav taws xob, DBEF yog qhov tsis xav tau qhov kev daws teeb meem zoo tshaj plaws hauv kev kho qhov muag.
Nws tsis tsuas yog hais txog qhov mob ntawm cov ntawv thov sab nraum zoov tab sis kuj tseem muab txoj hauv kev hloov kho tau yooj yim thiab txhim khu kev qha rau cov khoom siv. Yog tias koj tab tom txiav txim siab ua kom zoo dua koj cov khoom lag luam, xav txog kev tshawb nrhiav DBEF cov kev daws teeb meem sib xyaw ua ke- nws tuaj yeem ua rau koj cov lus pom nyob hauv khw.
