Tag nrho xim xim liab hauv hluav taws xob saib tsav teeb meem

Raws li kev txheeb cais, nyob rau hauv tag nrho cov xim xim xauv npo series, kev xa khoom yog 1/16, 1/8, 1/4, 1/2, static. Yuav ua li cas kom paub qhov sib txawv ntawm cov LED tag nrho xim xim kev xa duab? Ib txoj kev simplest yog suav cov LEDs ntawm LED qhov hluav taws xob zaub hluav taws xob thiab cov xov tooj ntawm 74HC595. Ntawm chav kawm, nws tseem yog ib qho tseem ceeb rau kev txheeb xyuas qhov kev hloov roj ntsha ntawm cov coj tus tsav LED.

Kev tshawb xam txuj: cov LEDs muab faib los ntawm tus xov tooj ntawm 74HC595 thiab muab faib ua 8 = feem ntawm ib lub luam theej duab

Qhov tiag tiag pixel LED zaub screen sib raug mus rau virtual LED hauv npo zaub: hauv luv luv, qhov tiag tiag pixel screen hais txog liab, ntsuab thiab xiav lub teeb-emitting tub tsim tsa lub vijtsam zaub. Kev ntsuam xyuas yog siv los ua kom muaj kev sib luag.

Virtual pixel yog lub software algorithm uas tswj qhov kawg ntawm lub teeb lub raj ntawm txhua lub xim mus koom rau hauv qhov kev pom ntawm ib qho pixels uas nyob ib sab, thiab tom qab ntawd ua rau muaj kev daws teeb meem loj dua nrog cov teeb txawb kom daws tau qhov teeb meem ntawm cov lus plaub zaug.

Hauv cov yeeb yaj duab puv xim, muaj 16 sweeps, 8 sweeps, 4 sweeps, thiab lwm yam, thiab muaj kev sib txawv ntawm lawv:

Ua ntej, kev xa tshuaj ntsuam ntawm LED cov duab tso ua lag luam yog txawv;

Thib ob, qhov ci ntawm LED lub vijtsam tso saib yog txawv (16s yog tsawg tshaj 8s tsawg tshaj li 4s);

Qhov peb, cov lus hais tsis zoo li qub, tej zaum yuav nkag siab tias pes tsawg tus tsav tsheb IC IC chips siv sib txawv (tib hom 16s yog qis dua 8s tsawg dua 4s)

Tam sim no LED cov ntxaij vab tshaus ntawm cov lag luam yuav tsum tau muab faib ua ob txoj hau kev: kev tshawb nrig txog kev sib tw thiab kev xaav dynamic! Kev thaij duab thev naus laus zis faib ua pixels zoo li qub thiab muaj txiaj ntsig zoo li qub! Dynamic PP kuj tseem muab faib ua dynamic duab thiab cov txuj ci virtual. Muaj 2 sweeps, 4 sweeps, 8 sweeps, thiab 16 sweeps.

Nws tau teev tias qhov pixel ntawm ib kab xim puv npo siv nyob rau hauv PH16 teb yog 16 * 8 (2R1G1B). Yog tias nws tsav los ntawm MBI5026, tus qauv siv tag nrho:

16 * 8 * (2 + 1 + 1) = 512 teeb, MBI5026 yog 16-ntsis nti, 512/16 = 32

1, yog tias koj siv 32 MBI5026 nti, nws yog qhov qub virtual

2. Yog tias koj siv 16 MBI5026 chips, nws yog dynamic 1/2 scan virtual

3. Yog tias koj siv 8 MBI5026 chips, nws yog dynamic 1/4 scan virtual

Yog hais tias nws yog xim puv npo lub teeb vaj huam sib luag coj pawg ob pawg teeb liab

4, nrog 24 MBI5026 nti, yog pixel tiag tiag tiag

5, nrog 12 MBI5026 nti, yog ib qho dynamic 1/2 cheb pixel

6, nrog 6 MBI5026 nti, yog ib tug dynamic 1/4 scan pixel
