Koj yuav tsum xyuam xim rau dab tsi thaum yuav khoom sab hauv tsev?
1. Tuag taw tes
Lub ntsiab lus tuag ntawm lub vijtsam sab hauv tsev yog ib qho taw qhia uas hais txog qhov ib txwm-on lossis ib txwm-dub ntawm lub vijtsam tam sim no.Ntau tus yuam sij ntawm qhov tuag taw tes yog txiav txim siab los ntawm qhov zoo ntawm qhov tuag.Qhov qis dua qhov taw tes tuag, qhov siab dua cov duab yuav ua tau.
2. Chromaticity
Lub chromaticity yog qhov teeb meem heev rau lub vijtsam sab hauv tsev.Yog tias chromaticity siab dhau lawm, nws yooj yim ua rau lub cev tsis pom kev thiab kev noj qab haus huv.Yog tias chromaticity tsawg dhau, cov duab tso saib yuav tsis meej.Raws li ib txwm muaj, lub chromaticity ntawm cov ntxaij vab tshaus sab hauv tsev yog 800cd / ㎡-2000cd / ㎡.Cov khoom sib txawv ntawm LED cov khoom lag luam muaj cov chromaticities sib txawv.
3. Xim oxidation
Cov cuab yeej oxidative ntawm lub vijtsam sab hauv tsev txhais tau hais tias cov xim ntawm lub vijtsam zaub yuav tsum ua raws li cov xim ntawm qhov chaw playback, thiaj li ua kom ntseeg tau qhov tseeb ntawm cov duab.
4. Flatness
Lub flatness ntawm lub vijtsam tuaj yeem cuam tshuam qhov zoo ntawm cov duab pom.Lub tiaj tus ntawm lub tsheb lub cev saum npoo ntawm lub vijtsam sab hauv tsev hauv kev lag luam yog tswj tsis pub dhau ± 1 hli.Ib feem ntawm lub protrusion los yog kev nyuaj siab ntawm lub tsheb lub cev nto yuav ua rau ib tug dig muag qhov chaw nyob rau hauv lub saib lub kaum sab xis ntawm cov zaub screen.Qhov zoo ntawm flatness yog txiav txim siab los ntawm kev siv tshuab, thiab cov chaw tsim khoom sab hauv tsev yuav tsum tau them sai sai rau qhov teeb meem no thaum tsim khoom.
5. Saib lub kaum sab xis
Qhov loj ntawm lub kaum sab xis saib ntawm lub vijtsam sab hauv tsev yog ib qho tseem ceeb hauv kev txiav txim siab ntawm pawg hom phiaj ntawm LED zaub.Qhov loj dua thiab siab dua qhov pom lub kaum ntse ntse, qhov dav ntawm lub hom phiaj ntawm pawg, thiab lub kaum sab xis saib yog cuam tshuam los ntawm kev ntim khoom ntawm LED tuag.Yog li ntawd, xyuam xim rau txoj kev ntim khoom ntawm qhov tuag thaum xaiv lub vijtsam sab hauv tsev.
