Cov ntaub ntawv no qhia txog txoj hauv kev thiab kev ceev faj rau xaiv cov duab LED sab hauv tsev. Thaum xaiv ib qho khoom siv sab hauv LED, ua ntej txiav txim siab koj cov kev xav tau tshwj xeeb, xws li kev npaj siv, pixel suab, thiab lub luag haujlwm tseem ceeb. LED zaub manufacturers yuav muab cov lus qhia tsim nyog thiab cov kev daws teeb meem raws li koj xav tau. Hauv qab no yog qee txoj hauv kev sau los ntawm cov tuam ntxhab rau koj siv:
Yuav ua li cas xaiv LED zaub?
1. Txiav txim siab seb koj lub LED zaub yuav siv sab hauv tsev lossis sab nraum zoov. Yog hais tias sab hauv tsev, nws yog sab hauv tsev LED zaub; Yog hais tias sab nraum zoov, nws yog sab nraum zoov LED zaub.
2. Txiav txim seb koj puas xav tau monochrome, bi-xim, lossis puv -xim zaub. Puv-xim txhais tau tias puv -xim LED zaub.
3. Txiav txim siab lub pixel suab, feem ntau hu ua P2.5, P6, P8, P10, thiab lwm yam. Yuav ua li cas txiav txim siab pixel suab? Ntawm no yog ib tug qauv: P=L / 1700, qhov twg P yog lub pixel suab nyob rau hauv mm, thiab L yog qhov ze tshaj saib nyob rau hauv mm; uas yog, P1.6 LED zaub yog tsim los saib ntawm qhov deb ntawm 2.7m lossis ntau dua.
Dab tsi yuav tsum tau xav txog thaum yuav ib qho khoom siv sab hauv LED?
I. Ntim daim ntawv. Sab hauv LED zaub muaj ob peb daim ntawv LED nto: ib lub teeb, sub-surface mount, peb-hauv-ib qhov chaw mount, thiab peb-hauv-ib lub mount, txhua qhov sib txawv. Qhov kom zoo dua ntawm qhov ntim ntim ntim yog qhov pom loj thiab lub teeb pom kev zoo sib xws. Nws yog ib qho yooj yim rau automate vuam thiab ua, thiab yog cov khoom tseem ceeb rau tag nrho - xim LED cov ntxaij vab tshaus, tab sis tus nqi yog tam sim no kuj siab; tib lub teeb muaj qhov pom me me me, qhov ci dua me ntsis, thiab tus nqi qis dua. Sub{11}}surface mount yog tiag tiag ib hom ntawm ib lub teeb. Tib lub teeb thiab sub-nto mount yog pheej yig thiab yog cov khoom hloov pauv.
II. Qhov ntom. Vim muaj cov hluav taws kub loj ntawm sab hauv tsev puv - xim LED chips thiab lub siab ceev ntawm kev tswj circuits, pixel ceev ntawm kev lag luam muaj puv - xim cov ntxaij vab tshaus tseem tsis tau siab heev.
III. Cov pixels tiag thiab virtual pixels. Zoo ib yam li sab nraum zoov puv - xim cov ntxaij vab tshaus, tus naj npawb ntawm pixels nyob sab hauv tsev puv - xim cov ntxaij vab tshaus kuj muab faib ua pixels tiag tiag thiab virtual pixels.
IV. LED nti. Ib qho zoo LED nti ua kom zoo ntawm LED.
V. Kev tsav tsheb. Txoj kev tsav tsheb ntawm sab hauv tsev puv - xim LED cov lus qhia yog kev tsav tsheb tsis tu ncua, siv kev tshuaj ntsuam dynamic (tsuas yog 1/4, 1/8, thiab lwm yam. scanning txoj kev). Nrog tib lub nti LED, 1/4 scan qhia xav tau ntau dua circuitry thiab muab qhov ci ci dua.
Hauv cov ntsiab lus: Thaum xaiv cov khoom siv sab hauv LED, txoj hauv kev kom raug yog xaiv cov khoom uas haum rau koj cov kev xav tau, tsis yog qhov muag tsis pom kev raws li tus nqi. Xaiv cov khoom tsim nyog yuav tso cai rau koj kom siv tau zoo dua ntawm LED zaub thiab ua kom muaj txiaj ntsig ntau dua. Qhov no xaus peb qhov kev sib tham txog yuav ua li cas xaiv LED zaub.
