Kev sib raug zoo ntawm qhov pom kev deb thiab qhov sib nrug ntawm LED zaub yog hu ua pixel pitch.Pixel pitch sawv cev rau qhov sib nrug ntawm txhua pixel (LED) ntawm cov zaub thiab ntsuas hauv millimeters.
Txoj cai dav dav yog tias lub pixel pitch yuav tsum me dua rau cov duab uas xav pom los ntawm qhov ze dua thiab loj dua rau cov duab uas xav pom los ntawm qhov deb.
Piv txwv li, yog tias LED zaub yog npaj los saib los ntawm qhov ze ze (sab hauv tsev lossis hauv cov ntawv thov xws li digital signage), qhov me me pixel suab, xws li 1.9mm lossis qis dua, yuav tsim nyog.Qhov no tso cai rau lub pixel ceev dua, ua rau cov duab zoo dua thiab cov ncauj lus kom ntxaws dua thaum saib ze.
Ntawm qhov tod tes, yog tias LED zaub yog npaj kom pom los ntawm qhov deb (sab nraum zoov loj-hom tso saib, billboards), qhov loj dua pixel suab yog nyiam.Qhov no txo tus nqi ntawm LED zaub system thaum tswj xyuas cov duab zoo ntawm qhov kev pom deb.Hauv cov xwm txheej zoo li no, pixel suab ntawm 6mm txog 20mm lossis ntau dua tuaj yeem siv.
Nws yog ib qho tseem ceeb kom nrhiav tau qhov sib npaug ntawm qhov pom qhov deb thiab pixel suab kom ntseeg tau tias kev pom kev pom kev zoo thiab tus nqi-zoo rau daim ntawv thov tshwj xeeb.
Kev sib raug zoo ntawm kev saib qhov deb thiab LED zaub suab yog txiav txim siab los ntawm pixel ceev thiab daws teeb meem.
· Pixel ceev: Pixel ceev ntawm LED zaub yog hais txog tus naj npawb ntawm pixels hauv ib cheeb tsam, feem ntau qhia hauv pixels ib nti (PPI).Qhov siab dua qhov pixel ceev, qhov ntom ntom ntawm pixels ntawm qhov screen thiab qhov pom tseeb dua cov duab thiab cov ntawv.Qhov ze ntawm qhov pom qhov deb, qhov siab dua qhov pixel ceev yuav tsum tau lav qhov pom tseeb ntawm cov zaub.
· Kev daws teeb meem: Qhov kev daws teeb meem ntawm LED zaub yog hais txog tag nrho cov pixels ntawm lub vijtsam, feem ntau yog qhia raws li pixel dav multiplied pixel qhov siab (xws li 1920x1080).Kev daws teeb meem siab dua txhais tau tias ntau pixels ntawm lub vijtsam, uas tuaj yeem nthuav tawm ntau dua thiab cov duab zoo dua.Qhov deb ntawm qhov pom qhov deb, qhov kev daws teeb meem qis dua tuaj yeem muab qhov pom tseeb txaus.
Yog li ntawd, ntau dua pixel ceev thiab daws teeb meem tuaj yeem muab cov duab zoo dua thaum saib cov kev ncua deb dua.Thaum saib ntev dua, qhov qis dua pixel ntom thiab cov kev daws teeb meem feem ntau tuaj yeem muab cov duab txaus siab.
