Nrog txoj kev loj hlob ntawm LED thev naus laus zis, qhov ci ntsa iab ntawm LED cov khoom siv hluav taws xob tau nce zuj zus, thiab qhov loj me tau txais me me thiab me me, uas qhia tau tias ntau LED hluav taws xob tso rau hauv tsev yuav dhau los ua tus qauv dav dav. Txawm li cas los xij, vim yog kev txhim kho ntawm LED ci ntsa iab thiab pixel ceev rau LED npo tswj thiab tsav tsheb kuj coj cov kev xav tau siab dua tshiab. Ntawm qhov kev tshuaj ntsuam sab hauv tsev, tam sim no txoj kev tswj hwm tau siv nyob rau hauv kab thiab txhua kab ntawm kev tswj hwm, uas yog, feem ntau hu ua hom scanning, tam sim no, LED hluav taws xob zaub tsav hom muaj qhov zoo li qub scanning thiab dynamic scanning. Ob hom kev soj ntsuam zoo li qub tau muab faib ua qhov zoo li qub pixels thiab zoo li qub virtual, dynamic scanning kuj muab faib ua cov duab tiag tiag thiab dynamic virtual.
Nyob rau hauv lub LED hluav taws xob zaub, tus naj npawb ntawm cov kab teeb nyob rau tib lub sij hawm thiab qhov piv ntawm cov kab nyob rau hauv tag nrho cov cheeb tsam, hu ua scanning hom. Thiab scanning kuj muab faib ua 1/2scan, 1/4 ibscan, 1/8 ibscan, 1/16scanthiab yog li ntawm ob peb txoj kev tsav tsheb. Uas yog hais tias, cov zaub tsis yog tib hom tsav, ces cov receiver card nqis kuj txawv. Yog tias daim npav txais tau pib siv rau hauv 1/4 scanning npo, tam sim no siv nyob rau hauv qhov kev tshuaj ntsuam zoo li qub, ces cov zaub ntawm cov zaub yuav yog txhua 4 kab ntawm cov kab ci. General txais daim npav tuaj yeem teeb tsa, txuas nrog daim npav xa khoom, tso saib, khoos phis tawj thiab lwm yam khoom siv loj, koj tuaj yeem nkag mus rau cov software cuam tshuam ntawm lub khoos phis tawj los teeb tsa. Yog li ntawm no yog thawj zaug los qhia txog LED hluav taws xob zaub scanning hom thiab lub hauv paus ntsiab lus.
- LED hluav taws xob zaub scanning hom.
1. Dynamic scanning: dynamic scanning yog los ntawm cov zis ntawm tus tsav tsheb IC mus rau pixel ntawm qhov kev siv ntawm "point-to-kum" tswj, dynamic scanning tswj Circuit Court yuav tsum tau, tus nqi qis dua qhov zoo li qub scanning, tab sis lub cov nyhuv pom tsis zoo, poob ntau dua ntawm qhov ci.
2. Static scanning: static scanning yog cov zis los ntawm tus tsav tsheb IC mus rau pixel ntawm qhov kev siv ntawm "point-to-point" tswj, zoo li qub scanning tsis tas yuav tsum tau tswj circuits, tus nqi yog siab tshaj qhov dynamic scanning, tab sis lub zaub nyhuv yog zoo, zoo stability, tsawg poob ntawm brightness thiab hais txog.
- LED hluav taws xob zaub 1/4 scan hom ua haujlwm txoj cai:
Nws txhais tau hais tias lub hwj chim mov V1-V4 ntawm txhua kab yog qhib rau 1/4 ntawm lub sij hawm txhua tus raws li cov kev cai tswj nyob rau hauv 1 ncej ntawm daim duab. Qhov kom zoo dua ntawm qhov no yog tias cov yam ntxwv ntawm LEDs tuaj yeem siv tau zoo dua thiab cov nqi kho vajtse tuaj yeem txo qis. Qhov tsis zoo yog tias txhua kab ntawm LEDs tsuas tuaj yeem tso saib 1/4 ntawm lub sijhawm hauv 1 thav duab.
- Raws li LED hluav taws xob zaub hom scanning txoj kev faib tawm:
1. Nyob sab hauv tsev puv xim LED hluav taws xob cov duab scanning hom: P4, P5 rau qhov tam sim no 1/16, P6, P7.62 rau qhov tam sim no 1/8.
2. Sab nraum zoov tag nrho xim LED hluav taws xob zaub screen scanning hom: P10, P12 rau qhov tam sim no 1/2, 1/4, P16, P20, P25 rau static.
3. Ib thiab ob xim LED hluav taws xob zaub screen scanning hom yog qhov tam sim no 1/4, tsis tu ncua tam sim no 1/8scan, tsis tu ncua tam sim no 1/16scan.
