Nyob rau hauv xyoo tas los no, LED hluav taws xob khoom lag luam tau nrov heev, tsav tag nrho LED zaub kev lag luam mus rau theem ntawm kev loj hlob sai.Ntxiv nrog rau kev tshaj tawm cov ntxaij vab tshaus, cov ntxaij vab tshaus ua yeeb yam, thiab cov ntxaij vab tshaus qhia kev tsheb uas tau siv dav rau sab nraum zoov, sab hauv LED cov lus tseem yog lub lag luam uas muaj peev xwm loj, suav nrog cov ntxaij vab tshaus loj hauv tsev thiab sab hauv hluav taws xob hauv tsev.Tab sis los ntawm ib qho kev pom, qhov tseeb, nyob rau hauv 10 xyoo dhau los los yog li ntawd, LED cov ntxaij vab tshaus qhia los ntawm feem ntau manufacturers tsis tau hloov ntau yam nyob rau hauv lub hauv paus system architecture, tab sis tau txhim kho mus rau ib tug tej yam degree raws li tej yam kev qhia. .Thiab kho.

Nyob rau tib lub sijhawm, kev nrov npe thiab kev txhawb nqa ntawm cov khoom lag luam ua tau zoo yog qhov lag luam, txawm hais tias thaum ntxov li ob peb xyoos dhau los, twb tau muaj cov khoom siv tsav tsheb IC nrog PWM (Pulse Width Modulation) muaj nuj nqi ntawm kev ua lag luam, thiab cov neeg koom nrog kev lag luam muaj. kuj pom zoo nrog PWM muaj nuj nqi.Nws muaj qhov zoo ntawm qhov siab refresh tus nqi thiab tsis tu ncua tam sim no.Txawm li cas los xij, vim yog tus nqi thiab lwm yam, kev ua lag luam sib koom ntawm cov khoom siv ua haujlwm siab ICs tseem tsis siab.Cov qauv yooj yim feem ntau yog siv nyob rau hauv kev ua lag luam (xws li Macroblock 5024/26 thiab lwm yam), cov khoom siv high-end feem ntau yog siv nyob rau hauv qee lub khw muag khoom LED screen uas them nyiaj ntau rau qhov zoo.

Txawm li cas los xij, nrog txoj kev loj hlob sai ntawm Shenzhen LED zaub ua lag luam, ntau thiab ntau tus neeg siv tau pib muab tso rau hauv cov kev xav tau ntawm cov ntxaij vab tshaus LED los ntawm kev pom cov teebmeem, kev sib kis, cov kev qhia, thiab cov txheej txheem playback.Qhov no tseem ua rau LED Screen cov khoom lag luam tab tom ntsib lub sijhawm tshiab rau kev tsim kho thev naus laus zis, thiab raws li "lub hlwb" ntawm tag nrho cov zaub system-LED tsav IC yuav ua lub luag haujlwm tseem ceeb.

Cov ntaub ntawv kis tau tus mob ntawm lub vijtsam LED thiab lub motherboard feem ntau siv cov ntaub ntawv sib kis (SPI), thiab tom qab ntawd synchronously xa cov ntaub ntawv thiab tswj cov ntaub ntawv los ntawm cov teeb liab pob ntawv multiplexing technology, tab sis thaum lub refresh npaum li cas thiab kev daws teeb meem zoo dua, Nws yog ib qho yooj yim los ua ib qho bottleneck nyob rau hauv cov ntaub ntawv kis tau tus mob, ua rau lub system instability.Tsis tas li ntawd, thaum thaj tsam ntawm lub vijtsam LED yog qhov loj, cov kab tswj feem ntau ntev heev, uas cuam tshuam rau electromagnetic cuam tshuam, uas cuam tshuam rau qhov zoo ntawm cov teeb liab kis tau tus mob.

Txawm hais tias qee cov tuam txhab lag luam tau tshaj tawm cov xov xwm tshiab hauv xyoo tas los no, yuav ua li cas muab cov neeg siv nrog kev ua tau zoo tiag tiag thiab cov khoom lag luam raug nqi yog qhov teeb meem tseem ceeb uas cuam tshuam rau kev lag luam.Txog rau qhov kawg no, qee cov tuam txhab lag luam tau npaj siab tias cov ntaub ntawv xa tawm txoj hauv kev ntawm LED cov ntxaij vab tshaus ceev yuav tsum tau pib los ntawm qib qis tshaj plaws thiab nrhiav kev daws teeb meem tshiab.

Nws yog ib qho tsim nyog sau cia tias kev tsim kho thev naus laus zis ntawm cov ntxaij vab tshaus LED tau koom nrog txhua yam ntawm cov saw hlau, suav nrog kev txhim kho cov tsav tsheb IC cov txheej txheem tsim khoom, kho vajtse ntawm kev tswj hwm, kev tsim kho ntse ntawm kev tswj software, thiab lwm yam. Cov kev tsim kho thev naus laus zis no xav tau IC tsim. manufacturers, tswj System developers, vaj huam sib luag manufacturers, thiab txawm tag nrho cov neeg siv yog zoo sib koom ua ke los ua txhaum lub "deadlock" ntawm kev lag luam daim ntawv thov.Tshwj xeeb tshaj yog nyob rau hauv txoj kev loj hlob ntawm kev tswj systems, yuav ua li cas zoo koom tes nrog IC tsim tuam txhab uas muag los txhim kho lub system kev ua tau zoo ntawm LED cov ntxaij vab tshaus thiab cov ntse theem ntawm kev tswj software yog qhov tseem ceeb tshaj plaws.
