Cov qauv kev daws teeb meem ntawm LED zaub yog: daws teeb meem=(screen length mm / dot pitch mm) * (screen qhov siab mm / dot pitch mm). Hauv cov qauv no, lub vijtsam ntev thiab qhov siab hais txog qhov loj ntawm lub cev ntawm LED zaub, feem ntau yog millimeters; dot pitch hais txog qhov kev ncua deb ntawm qhov nruab nrab ntawm ib lub teeb hlaws mus rau qhov chaw ntawm lub teeb hlaws uas nyob ib sab, kuj yog millimeters. cov
Kev sib raug zoo ntawm kev daws teeb meem thiab lub suab dot
Qhov me me ntawm qhov dot pitch, qhov kev daws teeb meem siab dua thiab siab dua qhov pom tseeb ntawm qhov screen. Piv txwv li, qhov dot pitch ntawm P2 yog 2 hli, thaum lub suab ntawm P0.9 tsuas yog 0.9mm, yog li qhov kev daws teeb meem ntawm P0.9 yuav siab dua. yog p2.
Piv txwv kev suav
Piv txwv li muaj ib qho LED zaub nrog qhov ntev ntawm 4 meters, qhov siab ntawm 2 meters, thiab ib tug dot suab ntawm 2 hli, ces nws cov kev daws teeb meem yog xam raws li nram no:
Screen ntev: 4000mm / 2mm=2000 pixels
Screen qhov siab: 2000mm / 2mm=1000 pixels
Yog li ntawd, qhov kev daws teeb meem ntawm LED zaub no yog 2000 pixels * 1000 pixels.
Los ntawm cov qauv no thiab piv txwv, peb tuaj yeem nkag siab meej txog yuav ua li cas los laij cov kev daws teeb meem ntawm LED zaub thiab xaiv qhov tsim nyog dot suab raws li xav tau kom ua tiav qhov zoo tshaj plaws clarity thiab daws teeb meem.
