(1) Pixel: Nws yog qhov tsawg tshaj plaws imaging unit ntawm LED zaub. Feem ntau hu ua "dots" lossis "pixels".
(2) Zaub module: Nws yog tsim los ntawm ntau lub pixels thiab yog qhov tsawg tshaj plaws ntawm LED zaub screen ntawm nws tus kheej hauv cov qauv. Lub vijtsam sab hauv siv ib qho 8x8 zaub module, uas yog, txhua qhov zaub module muaj 64 pixels; lub vijtsam sab nraum zoov siv ib lub teeb hlaws, uas feem ntau muaj 1-3 teeb hlaws ntawm tib lossis xim sib txawv los tsim ib pixel ntawm lub module.
(3) Display module: ib chav tsev ywj pheej uas txiav txim siab los ntawm lub voj voog thiab cov qauv kev teeb tsa thiab muaj cov khoom ua haujlwm los tsim cov duab LED. Cias muab tso, txhawm rau pab txhawb kev sib dhos thiab tso saib, cov khoom lag luam ib nrab tiav los ntawm lub Hoobkas feem ntau yog muab rau hauv daim ntawv ntawm cov zaub modules, thiab ntau cov zaub modules thiab cov zaub tsav tsheb ua ke. Cov ntxaij vab tshaus hauv tsev feem ntau hu ua "unit boards"; Cov ntxaij vab tshaus sab nraum zoov feem ntau hu ua "modules", thiab ntau lub modules ua ke nrog chassis, kiv cua, cov khoom siv hluav taws xob, thiab lwm yam los tsim ib "lub thawv", uas feem ntau yog siv rau cov ntxaij vab tshaus puv xim loj. Sab hauv tsev screen tsev feem ntau muaj 64x32 (64 kab thiab 32 kab, muaj li ntawm 32 modules), 64x16 (64 kab thiab 16 kab, muaj li ntawm 16 modules), thiab lwm yam .; Sab nraum zoov screen modules feem ntau muaj 64x32, 32x32, 32x16, 16x16, 16x8 ntau yam.
(4) LED zaub screen: Chav tsev / module / lub thawv yog spliced ua ke nyob rau hauv ib txoj kev, thiab daim ntawv tswj / tswj system, lub hwj chim mov thiab ncej yog ntxiv rau tsim ib tug LED zaub.
(5) Point nrug: Nws yog qhov kev ncua deb ntawm 2 pixels. Feem ntau nyob ntawm qhov kev ncua deb ntawm tus saib. Feem ntau lub tswvyim ntawm dot pitch yog siv rau sab nraum zoov cov ntxaij vab tshaus, xws li P6, P7.62, P8, P10, P12, P16, P20, thiab lwm yam, hauv millimeters. Qhov kev ncua deb ntawm sab nraum zoov cov ntxaij vab tshaus yog feem ntau nyob rau hauv 30 meters, thiab modules tsis loj tshaj P16 (16mm) yog siv. Qhov denser lub dot pitch, qhov muag ntau dua qhov pom kev mob stroke, ntau pixels ib cheeb tsam, thiab qhov kim dua qhov screen.
(6) Scanning method: Feem ntau, muaj teeb meem ntawm scanning txoj kev rau sab nraum zoov screen modules. Hom scanning txiav txim siab daim ntawv txuas ntawm cov modules. Scanning hom muaj xws li 1/16, 1/8, 1/4, 1/2, thiab zoo li qub. Vim hais tias LED zaub yog refreshed kab los ntawm kab, lub scanning txoj kev kuj txiav txim siab cov zaub refresh txoj kev. Piv txwv li, 1/16 yog los kho 1 kab ntawm ib lub sij hawm, thiab 16 kab yog ib lub voj voog scan, uas xav tau plaub lub cim ABCD los tswj; 1/8 yog Txhua zaus ib kab rov ua dua tshiab, 8 kab yog ib lub voj voog scan, uas yuav tsum tau tswj los ntawm peb lub cim ABC; lwm tus yog deduced nyob rau hauv lem.
Yog tias tib lub teeb ci LED siv, qhov ci ntawm 1/16 scan yog qis dua li ntawm 1/8, thiab qhov zoo li qub (1/1) ci ntsa iab yog qhov siab tshaj. Cov ntxaij vab tshaus sab hauv feem ntau siv 1/16 scan, thiab cov ntxaij vab tshaus sab nrauv thiab sab nrauv feem ntau siv 1/16 lossis 1/8. Rau qhov chaw uas lub vijtsam feem ntau raug tshav ntuj, nws yog qhov zoo tshaj plaws los siv 1/4 scan.
