Tus nqi ntawm sab hauv LED zaub yog kwv yees li ob peb txhiab RMB ib square meter. Tus nqi sib txawv nyob ntawm tus qauv, thiab seb koj xav tau tus nqi siab lossis qis qis dua. Lub pixel suab feem ntau me me, feem ntau yog Φ3mm txog Φ8mm, thiab thaj chaw tso saib feem ntau yog ob peb mus rau kaum square meters.
1. Los ntawm cov xim puag, nws tuaj yeem muab faib ua: Ib qho -xim loj screen: ib xim (liab lossis ntsuab). Dual-xim loj screen: liab thiab ntsuab dual-xim, 256 qib grey, tuaj yeem tso saib 65536 xim. Tag nrho -xim loj screen: liab, ntsuab, thiab xiav peb lub ntsiab xim, ib tug puv -xim loj screen nrog 256 grey theem tuaj yeem tso saib ntau dua 16 lab xim.
2. Los ntawm kev faib cov cuab yeej siv: LED cov vijtsam loj: Cov khoom siv tshuaj ntsuam loj yog 7- ntu cov raj, tsim nyog rau kev ua cov ntxaij vab tshaus, cov paj paj, thiab lwm yam, tso saib cov ntxaij vab tshaus digital loj. LED dot matrix graphic screen loj: Cov khoom siv yog dot matrix zaub module tsim los ntawm ntau yam teeb pom kev zoo sib xws -emitting diodes, haum rau kev ua si cov ntawv nyeem thiab cov ntaub ntawv duab. LED video loj screen: Cov cuab yeej tso saib yog tsim los ntawm ntau lub teeb-emitting diodes thiab tuaj yeem tso saib ntau yam ntaub ntawv video xws li cov yeeb yaj kiab thiab cov animations.
3. Los ntawm lub teeb -emitting point txoj kab uas hla thiab qhov sib nrug: Sab hauv tsev loj screen (los ntawm txoj kab uas hla): Φ3mm, Φ3.75mm, Φ5mm, Sab nraum zoov loj screen (los ntawm qhov sib nrug): PH10, PH12, PH14, PH16, PH20, PH25, PH31.25} tal hom, PH static scrolling, ntsug scrolling, thiab nplooj tig zaub. Ib qho module tswj thiab tsav 12 (ntau tuaj yeem tswj tau 24) 8x8 dot matrixes, tag nrho ntawm 16x48 dot matrixes (lossis 32x48 dot matrixes), uas yog 12 zaug (lossis 24 zaug) uas ntawm ib qho MAX7219 (lossis PS7219, HDL727 modules) zoo ib yam li tus tsav tsheb, PS7219, HDL729! Nws tuaj yeem ua cascaded los ua ib qho loj dot matrix loj screen. Nws muaj cov txiaj ntsig zoo, kev siv hluav taws xob tsawg, thiab pheej yig dua li siv MAX7219 circuits.
