Kev xaiv ntawm LED zaub taw tes sib nrug yog cuam tshuam nrog ob yam:
Ua ntej, qhov pom kev deb ntawm LED zaub
Lub vijtsam zaub nyob qhov twg, thiab nyob deb npaum li cas tib neeg sawv los saib nws, yog qhov tseem ceeb hauv kev txiav txim siab lub suab thaum xaiv lub vijtsam LED.
Feem ntau, muaj cov qauv rau kev pom qhov deb = dot pitch / (0.3 ~ 0.8), uas yog qhov kwv yees ntau yam.Piv txwv li, rau cov zaub nrog lub pixel pitch ntawm 16mm, qhov zoo tshaj plaws saib nrug yog 20 ~ 54 meters.Yog tias qhov chaw nres tsheb ze ze dua qhov tsawg kawg nkaus, koj tuaj yeem paub qhov txawv ntawm pixels ntawm lub vijtsam.Lub graininess muaj zog dua, thiab koj tuaj yeem sawv deb.Tam sim no, tib neeg lub qhov muag tsis tuaj yeem paub qhov txawv ntawm cov ntsiab lus.(Peb tsom rau qhov pom kev ib txwm, tsis suav nrog myopia thiab hyperopia).Qhov tseeb, qhov no kuj yog ib daim duab ntxhib.
Rau sab nraum zoov LED cov ntxaij vab tshaus, P10 lossis P12 feem ntau yog siv rau qhov luv luv, P16 lossis P20 rau qhov nyob deb, thiab P4 ~ P6 rau cov ntxaij vab tshaus sab hauv tsev, thiab P7.62 lossis P10 rau qhov nyob deb.
Thib ob, tag nrho cov pixels ntawm LED zaub
For video, the basic format is VCD with a resolution of 352288, thiab cov hom ntawv ntawm DVD yog 768576. Yog li ntawd, rau qhov kev tshuaj ntsuam video, peb pom zoo kom qhov tsawg kawg nkaus daws teeb meem tsis tsawg tshaj li 352 * 288, thiaj li hais tias cov zaub nyhuv yog zoo txaus.Yog tias nws qis dua, nws tuaj yeem tshwm sim, tab sis nws yuav tsis ua tiav cov txiaj ntsig zoo dua.
Rau ib leeg thiab dual thawj xim LED zaub uas tsuas yog tso saib cov ntawv thiab cov duab, cov kev daws teeb meem yuav tsum tsis siab.Raws li qhov loj me, qhov tsawg kawg nkaus tso saib ntawm 9th font tuaj yeem txiav txim siab raws li koj cov ntawv ntim.
Yog li ntawd, feem ntau xaiv LED zaub, qhov me me ntawm qhov chaw me me, qhov zoo dua, qhov siab dua qhov kev daws teeb meem yuav yog, thiab cov zaub yuav pom tseeb.Txawm li cas los xij, yam xws li tus nqi, kev xav tau, thiab qhov kev thov yuav tsum tau txiav txim siab dav.
