Raws li kev txheeb cais, nyob rau hauv tag nrho-xim LED zaub series cov khoom, cov txheej txheem scanning yog 1/16, 1/8, 1/4, 1/2, static. Yuav ua li cas paub qhov txawv ntawm LED puv xim zaub scanning txoj kev? Ib qho ntawm txoj hauv kev yooj yim tshaj plaws yog suav cov lej ntawm LEDs ntawm LED hluav taws xob zaub screen tsev board thiab tus naj npawb ntawm 74HC595. Ntawm chav kawm, nws kuj yuav tsum tau ua ke nrog cov kev tsom xam tshwj xeeb ntawm cov coj LED tsav scanning yam ntxwv.
Full xim coj zaub
Txoj kev suav: tus naj npawb ntawm LEDs muab faib los ntawm tus lej ntawm 74HC595 thiab tom qab ntawd muab faib los ntawm 8=ib feem ntawm qhov scan
Qhov tiag-pixel LED zaub screen sib haum mus rau lub virtual LED hluav taws xob zaub screen: hauv luv luv, lub pixel tiag tiag yog hais txog lub teeb liab, ntsuab thiab xiav lub teeb-emitting raj uas tsim lub vijtsam. Txhua ntawm peb lub teeb-emitting raj uas tsim lub vijtsam zaub tsuas yog koom nrog ib pixel thaum kawg. Daim ntawv thov kev yees duab kom ua tiav qhov ci ntsa iab.
Lub pixel virtual siv software algorithm los tswj lub teeb-emitting raj ntawm txhua xim los koom rau hauv cov duab ntawm ntau lub pixels uas nyob ib sab, thiab tom qab ntawd siv cov raj tsawg dua los ua kom tiav qhov kev daws teeb meem loj dua, uas tuaj yeem ua kom cov zaub daws teeb meem los ntawm plaub zaug.
Nyob rau hauv tag nrho-xim LED zaub screen series cov khoom lag luam, muaj 16 scans, 8 scans, 4 scans, thiab lwm yam, thiab tseem muaj qhov sib txawv hauv qab no:
1. Txoj kev scanning ntawm LED zaub screen yog txawv;
2. Qhov ci ntsa iab ntawm LED cov khoom siv hluav taws xob muaj qhov sib txawv (16s tsawg dua 8s tsawg dua 4s);
3. Cov lus hais tsis zoo ib yam, tej zaum nws nkag siab tias tus naj npawb ntawm cov tsav IC chips siv tsis zoo ib yam (16s ntawm tib hom yog qis dua 8s thiab qis dua 4s)
Tam sim no LED cov ntxaij vab tshaus ntawm kev ua lag luam tuaj yeem faib ua ob txoj hauv kev: static scanning thiab dynamic scanning! Static scanning tau muab faib ua cov pixels tiag tiag thiab zoo li qub virtual! Dynamic scanning kuj muab faib ua cov duab tiag tiag thiab dynamic virtual. Muaj 2 scans, 4 scans, 8 scans, thiab 16 scans.
Los piav qhia: Ib qho xim puv xim module pixel rau PH16 hauv daim teb yog 16 * 8 (2R1G1B). Yog tias nws tau tsav los ntawm MBI5026, cov qauv siv yog:
16 * 8 * (2 ntxiv rau 1 ntxiv 1)=512 teeb, MBI5026 yog 16-ntsis nti, 512/16=32
1. Yog tias 32 MBI5026 chips siv, nws yog static virtual.
2. Yog tias 16 MBI5026 chips siv, nws yog dynamic 1/2 scan virtual.
3. Yog tias 8 MBI5026 chips siv, nws yog dynamic 1/4 scan virtual.
Yog hais tias ob lub teeb liab ntawm cov xim puv xim LED zaub vaj huam sib luag txuas nrog hauv series:
4. Siv 24 MBI5026 chips, uas yog zoo li qub pixels.
5. Siv 12 MBI5026 chips, nws yog dynamic 1/2 scan tiag pixel.
6. Siv 6 MBI5026 chips, nws yog dynamic 1/4 scanning tiag pixel
