Kev daws teeb meem yog qhov taw qhia tseem ceeb los ntsuas qhov pom tseeb ntawm cov zaub coj, nws tseem yog qhov kev txhawj xeeb tshaj plaws rau cov neeg siv khoom lag luam {}}
Kev daws teeb meem ntawm ib qho zaub coj yog txiav txim siab los ntawm kev daws teeb meem ntawm ib qho kev daws teeb meem ntawm ib qho modulle × qhov kom muaj nuj nqis.
Cia peb coj P3 . 91 qauv ua piv txwv.
Module Loj thiab Pixel Suab: Ua ntej, koj yuav tsum paub lub cev nqaij daim tawv (xws li 250 hli) {} lub pixel (xws li 30 hli)}}}
Xam cov qauv daws teeb meem: module loj ÷ pixel suab, los laij cov kab rov tav thiab ntsug ntawm module .
Rau p3.91 module:
Kab rov tav resolution=250 hli ÷ 3.91mm ≈ 3.91mm ≈ 64 (sib npaug nce) pixels
Ntsug resolution=250 hli ÷ 3.91mm ≈ 3.91mm ≈ 64 (sib npaug nce) pixels
Yog li no, daws teeb meem ntawm ib p3 {{. 91 module yog 64x64 pixels.
Yuav ua li cas los xam qhov ntau ntawm cov modules rau ib qho zaub LED?
Yog tias cov neeg siv khoom thov cov zaub coj nrog 16: 9 piv, 4800mm dav X 2700mm siab .
Kom muaj nuj nqis ntawm kab rov tav hloov {}} dis dis diset dav ÷ mod modu dav dav ≈ 4500mm ÷ 250 hli ≈ 250 hli ≈)
Kom muaj nuj nqis ntawm ntsug modules= displece qhov siab ÷ mod modu qhov siab ≈ 2400mm ≈ 250 hli ≈ 11 (puag ncig)
Yog li ntawd, qhov loj me ntawm LED screen yuav 5000mmx2750mm .
Txhawm rau suav tag nrho cov kev daws teeb meem: Module Qhov X Module daws cov kev daws teeb meem ntawm cov zaub .
Tag nrho kab rov tav pixels=64 pixels / module × 20= 1280 pixels
Tag nrho ntsug pixels=64 pixels / module × 11= 704 pixels
Yog li ntawd, daws teeb meem ntawm no cov zaub coj yog 1280x704 pixels.
