LED zaub yog cov khoom siv vaj huam sib luag tiaj tiaj hauv peb lub neej, uas muaj qhov zoo ntawm cov xim ci, qhov dav dynamic ntau, siab ci thiab lub neej ntev. Yog li koj paub ntau npaum li cas txog cov lus qhia txog LED? Hnub no, cia peb ua raws li tus editor ntawm YONGS LED zaub kom nkag siab luv luv txog cov ntsiab lus ntawm LED zaub yog dab tsi.
1. LED brightness
Lub ci ci ntawm lub teeb-emitting diodes ntawm sab nraum zoov LED zaub feem ntau qhia los ntawm Luminous siv, thiab chav tsev yog candela cd; 1000ucd (microcandela)=1 mcd (millicandela), 1000mcd=1 cd. Lub teeb siv ntawm ib qho LED rau sab hauv tsev feem ntau yog 500ucd-50 mcd, thaum lub teeb siv ntawm ib qho LED rau sab nraum zoov feem ntau yuav tsum yog 100 mcd-1000 mcd, lossis ntau tshaj 1000 mcd.
2. LED pixel module
Cov LEDs yog teem rau hauv matrices los yog cwj mem, prefabricated rau hauv cov qauv me me modules. Cov ntxaij vab tshaus siv sab hauv tsev feem ntau yog 8 * 8 pixel modules thiab 8-cov cim 7- ntu digital modules. Sab nraum zoov zaub pixel modules muaj 4 * 4, 8 * 8, 8 * 16 pixels thiab lwm yam specifications. Lub pixel module rau sab nraum zoov cov ntxaij vab tshaus tseem hu ua tube bundle module vim hais tias txhua pixel yog tsim los ntawm ntau tshaj ob LED raj bundles.
3. Pixel thiab pixel txoj kab uas hla
Txhua LED lub teeb-emitting unit (dot) uas tuaj yeem tswj tau tus kheej hauv lub vijtsam LED yog hu ua pixel (lossis pixel). Pixel txoj kab uas hla ∮ hais txog txoj kab uas hla ntawm txhua pixel hauv millimeters.
Rau cov ntxaij vab tshaus sab hauv tsev, feem ntau yog ib qho LED nrog ib lub voj voog. Nyob sab hauv tsev pixel calibrations feem ntau yog ∮3.0, ∮3.75, ∮5.0, ∮8.0, thiab lwm yam. Ntawm lawv, ∮3.75 thiab ∮5.{{ 11}} ntau dua.
Nyob rau hauv ib puag ncig sab nraum zoov, txhawm rau txhim kho qhov ci ntsa iab thiab nce qhov pom kev deb, ib pixel muaj ntau tshaj ob pawg LEDs; txij li ntau tshaj ob pawg LEDs feem ntau tsis ncig, lub pixel txoj kab uas hla ntawm cov khoom sab nraum zoov zaub screen feem ntau qhia los ntawm qhov nruab nrab qhov sib nrug ntawm ob pixels. : □10, □11.5, □16, □22, □25.
4. Dot suab, pixel ceev thiab cov ntaub ntawv muaj peev xwm
Qhov nruab nrab ntawm qhov deb lossis dot pitch (Dot Pitch) ntawm ob pixels ntawm LED zaub screen; tus naj npawb ntawm pixels ib cheeb tsam yog hu ua pixel ceev; tus naj npawb ntawm cov ntsiab lus tso tawm hauv ib cheeb tsam yog hu ua cov ntaub ntawv muaj peev xwm. Lub ntsiab lus ntawm peb qhov no yog los piav txog tib lub tswv yim: dot pitch qhia txog pixel ntom ntawm qhov kev ncua deb ntawm ob pixels, dot pitch thiab pixel ceev yog lub zog ntawm lub vijtsam zaub; cov ntaub ntawv muaj peev xwm yog cov ntaub ntawv nqa lub peev xwm ntawm pixel ceev kom muaj nuj nqis.
Qhov me me ntawm qhov dot pitch, qhov siab dua pixel ceev, cov ntaub ntawv muaj peev xwm ntau dua, thiab qhov ze qhov pom qhov deb.
Qhov loj dua qhov dot pitch, qhov qis dua pixel ceev, qhov me me ntawm cov ntaub ntawv muaj peev xwm, thiab qhov ntev ntawm qhov kev ncua deb haum rau saib.
5. Kev daws teeb meem
Tus naj npawb ntawm kab thiab kab ntawm LED zaub pixels yog hu ua kev daws teeb meem ntawm LED zaub. Kev daws teeb meem yog tag nrho cov pixels ntawm cov zaub, uas txiav txim siab cov ntaub ntawv muaj peev xwm ntawm cov zaub.
6, LED zaub (LED Vaj Huam Sib Luag)
LED pixel modules tau sib sau ua ke thiab muab tso rau hauv ib lub matrix raws li qhov loj me, nrog rau cov zaub tshwj xeeb tsav tsheb, DC voltage stabilized fais fab mov, software, thav duab thiab kho kom zoo nkauj sab nraud, thiab lwm yam, los tsim ib qho screen LED.
7. Greyscale
Greyscale hais txog qib ntawm lub teeb thiab tsaus hloov hauv pixel lub teeb. Greyscale ntawm cov xim thawj feem ntau yog nyob ntawm 8 txog 1024 qib. Piv txwv li, yog tias qhov grey nplai ntawm txhua qhov xim thawj yog 256 qib, rau lub vijtsam xim thawj dual, cov xim xim yog 256 × 256=64K xim, uas tseem hu ua 256- xim zaub screen.
8. Ob chav xim thawj
Feem ntau ntawm cov xim LED hnub no yog ob lub xim xim xim, uas yog, txhua pixel muaj ob lub LED tuag: ib tug yog liab tuag, lwm yam yog ntsuab tuag. Thaum lub teeb liab tuag nyob rau, lub pixel yog liab, thaum ntsuab tuag nyob rau, lub pixel yog ntsuab, thiab thaum ob leeg liab thiab ntsuab tuag nyob rau tib lub sij hawm, lub pixel yog daj. Ntawm lawv, liab thiab ntsuab hu ua thawj xim.
9. Xim tag nrho
Liab thiab ntsuab ob lub ntsiab xim ntxiv rau xiav thawj xim, peb cov xim tseem ceeb yog xim tag nrho. Txij li cov thev naus laus zis rau kev tsim cov xim xiav tag nrho thiab cov xim ntsuab ntshiab yog tam sim no paub tab, xim puv yog siv hauv khw.
