LED zaub yog ib qho khoom siv uas siv lub teeb-emitting diodes (LEDs) ua lub teeb-emitting ntsiab los tso saib duab, yeeb yaj duab, animations thiab lwm yam ntaub ntawv los ntawm hluav taws xob cov ntxaij vab tshaus. LED zaub muaj qhov zoo ntawm qhov ci ci, kev siv hluav taws xob tsawg, lub neej ntev, kev pom dav dav, thiab lwm yam, thiab yog siv dav hauv kev tshaj tawm sab hauv thiab sab nraum zoov, kev thauj mus los, kev ua si, kev lom zem thiab lwm yam. Txhawm rau kom ntseeg tau cov txiaj ntsig pom thiab lub zog txuag hluav taws xob ntawm LED zaub screen, nws yog ib qho tsim nyog los xam qhov screen cheeb tsam thiab ci ntsa iab.
1. Tus qauv ntawm kev xam qhov screen cheeb tsam ntawm LED zaub screen
Qhov screen cheeb tsam ntawm LED zaub yog hais txog qhov loj ntawm nws qhov chaw ua haujlwm zoo, feem ntau yog square meters. Txhawm rau xam qhov screen cheeb tsam ntawm LED zaub, cov kev txwv hauv qab no yuav tsum paub:
1. Dot spacing: qhov chaw nruab nrab ntawm txhua pixel thiab cov pixels uas nyob ib sab, feem ntau yog millimeters. Qhov me me ntawm qhov dot pitch, qhov siab dua qhov pixel ceev, qhov kev daws teeb meem siab dua, qhov pom tseeb dua, tab sis tus nqi siab dua. Lub dot pitch feem ntau txiav txim siab raws li qhov tseeb daim ntawv thov scenario thiab saib nyob deb.
2. Module loj: txhua lub module muaj ob peb pixels, uas yog lub hauv paus ntawm LED zaub. Module loj yog txiav txim los ntawm tus naj npawb ntawm kab rov tav thiab ntsug pixels, feem ntau hauv centimeters. Piv txwv li, P10 module txhais tau tias txhua lub module muaj 10 pixels kab rov tav thiab ntsug, uas yog, 32 × 16 = 512 pixels, thiab module loj yog 32 × 16 × 0.1 = 51.2 square centimeters.
3. Screen loj: tag nrho LED zaub yog spliced los ntawm ob peb modules, thiab nws loj yog txiav txim los ntawm tus naj npawb ntawm kab rov tav thiab ntsug modules, feem ntau nyob rau hauv meters. Piv txwv li, P10 puv xim npo nrog qhov ntev ntawm 5 meters thiab qhov siab ntawm 3 meters txhais tau hais tias muaj 50/0.32 = 156 modules nyob rau hauv txoj kab rov tav thiab 30/0.16 = 187 modules nyob rau hauv txoj kev ntsug.
2. Tus qauv ntawm kev xam qhov ci ntawm LED zaub
Qhov ci ntsa iab ntawm LED zaub yog hais txog kev siv lub teeb uas nws tawm hauv qee qhov xwm txheej, feem ntau hauv candela ib square meter (cd / m2). Qhov siab dua qhov ci ntsa iab, lub teeb muaj zog dua, qhov sib txawv ntau dua, thiab muaj zog tiv thaiv kev cuam tshuam. Qhov ci ntsa iab yog feem ntau txiav txim siab raws li qhov tseeb daim ntawv thov ib puag ncig thiab saib lub kaum ntse ntse.
1. Lub ci ci ntawm ib lub teeb ci LED: lub teeb siv hluav taws xob tawm los ntawm txhua lub teeb xim LED, feem ntau yog hauv millicandela (mcd). Lub ci ci ntawm ib lub teeb ci LED yog txiav txim siab los ntawm nws cov khoom siv, txheej txheem, tam sim no thiab lwm yam, thiab qhov ci ntawm LED teeb ntawm cov xim sib txawv kuj txawv. Piv txwv li, qhov ci ntawm LED teeb liab feem ntau yog 800-1000mcd, qhov ci ntawm ntsuab LED teeb feem ntau yog 2000-3000mcd, thiab qhov ci ntawm xiav LED teeb feem ntau yog 300-500mcd.
2. Qhov ci ntsa iab ntawm txhua pixel: Txhua pixel yog tsim los ntawm ntau lub teeb ci LED ntawm cov xim sib txawv, thiab lub teeb ci tawm los ntawm nws yog qhov sib npaug ntawm qhov ci ntawm txhua xim LED teeb, feem ntau yog hauv candela (cd) raws li chav tsev. Lub brightness ntawm txhua pixel yog txiav txim los ntawm nws cov muaj pes tsawg leeg thiab kev faib ua feem, thiab brightness ntawm txhua pixel ntawm ntau hom ntawm LED zaub kuj txawv. Piv txwv li, txhua pixel ntawm P16 puv xim npo muaj 2 liab, 1 ntsuab, thiab 1 xiav LED teeb. Yog tias 800mcd liab, 2300mcd ntsuab, thiab 350mcd xiav LED teeb siv, qhov ci ntawm txhua pixel yog (800 × 2 + 2300 + 350) = 4250mcd = 4.25cd.
3. Lub zuag qhia tag nrho ci ntsa iab ntawm lub vijtsam: lub teeb ci tawm los ntawm tag nrho LED zaub yog qhov sib npaug ntawm qhov ci ntsa iab ntawm tag nrho cov pixels faib los ntawm thaj chaw tshuaj ntsuam, feem ntau hauv candela ib square meter (cd / m2) raws li chav tsev. Tag nrho qhov ci ci ntawm lub vijtsam yog txiav txim siab los ntawm nws qhov kev daws teeb meem, hom scanning, tsav tam sim no thiab lwm yam. Ntau hom LED cov ntxaij vab tshaus muaj qhov sib txawv ntawm qhov ci ci. Piv txwv li, qhov kev daws teeb meem ib square ntawm P16 puv-xim npo yog 3906 DOT, thiab cov txheej txheem scanning yog 1/4 scanning, yog li nws theoretical siab tshaj qhov ci yog (4.25 × 3906 / 4) = 4138.625 cd / m2.
3. Cov ntsiab lus
Kab lus no qhia txog cov txheej txheem ntawm kev suav cov cheeb tsam thiab qhov ci ntawm lub vijtsam LED, thiab muab cov qauv sib xws thiab cov piv txwv. Los ntawm cov txheej txheem no, cov teeb pom kev zoo LED tuaj yeem xaiv tau raws li qhov xav tau tiag tiag thiab cov xwm txheej, thiab cov txiaj ntsig pom thiab kev txuag hluav taws xob tuaj yeem ua kom zoo. Tau kawg, hauv kev siv tswv yim, lwm yam yuav tsum tau xav txog, xws li qhov cuam tshuam ntawm ambient lub teeb, kub thiab av noo, tshav kub dissipation, thiab lwm yam ntawm kev ua haujlwm thiab lub neej ntawm LED zaub.
LED zaub yog daim npav lag luam zoo nkauj hauv lub neej niaj hnub no. Nws tuaj yeem tsis tsuas yog tso saib cov ntaub ntawv, tab sis kuj qhia txog kab lis kev cai, tsim kom muaj huab cua thiab txhim kho cov duab. Txawm li cas los xij, txhawm rau kom tau txais cov txiaj ntsig siab tshaj plaws ntawm LED zaub, nws yog ib qho tsim nyog yuav tsum paub qee txoj hauv kev suav cov txheej txheem, tsim tsim nyog thiab xaiv qhov screen thiab qhov ci. Tsuas yog nyob rau hauv txoj kev no peb tuaj yeem ua kom pom tseeb, txuag hluav taws xob, kev tiv thaiv ib puag ncig, kav ntev thiab kev lag luam.
