Raws li kev lag luam micro-pitch txuas ntxiv kom sov, 4K thiab 8K siab txhais tau maj mam dhau los ua tus qauv tshiab rau cov lus qhia LED, thiab kev lag luam xav tau rau cov lus qhia siab tau nce.COB , leej twg tuaj yeem tau txais kev paub txog kev lag luam ntawm txoj kev ntawm micro-pitch zaub? Cov txheej txheem ntim khoom no muaj lawv tus kheej zoo, tab sis lub sijhawm ntawm micro-pitch tau los. Raws li lub vanguard ntawm micro-spacing era, COB tau dav lees paub los ntawm kev ua lag luam. Nrog kev loj hlob tseem ceeb ntawm covP0.9 LED zaub kev lag luam xyoo no, COB tau dhau los ua tus thawj coj ntawm sab hauv tsev siab txhais LED zaub. Nyob rau hauv lub neej yav tom ntej, raws li qhov sib nrug me me Mus down, COB yuav yog cov khoom tseem ceeb iteration kev taw qhia ntawm kev ua lag luam.
Nrog kev nce qib txuas ntxiv ntawm COB thev naus laus zis, xyoo nomicro-pitch LED zaub , hom cathode, flip-chip, huab hwm coj hloov pauv thiab lwm cov ntsiab lus tau dhau los ua qhov tseem ceeb ntawm cov xov xwm ntau zaus, cov thev naus laus zis no yog dab tsi? Yuav ua li cas txiav txim siab lub neej yav tom ntej ntawm COB technology micro-pitch rau?
Common cathode thev naus laus zis - txuag hluav taws xob, siab ceev thiab siv hluav taws xob tsawg
Cov khoom siv LED pom zoo siv hom anode (zoo ncej) fais fab mov hom, tam sim no ntws los ntawm PCB board mus rau lub teeb hlaws, thiab cov teeb pom kev zoo anode hlaws thiab cov tsav tsheb sib txuas IC thiab RGB teeb hlaws siv rau kev sib koom ua ke fais fab mov. Feem ntau cathode hais txog cov cathode (tsis zoo ncej) fais fab mov txoj kev, siv cov cathode teeb hlaws dai thiab ib qho tshwj xeeb cov cathode tsav IC scheme, R thiab GB yog cais powered, thiab tam sim no dhau los ntawm lub teeb hlaws thiab ces mus rau IC. cathode. Tom qab siv cov cathode nquag, peb tuaj yeem muab qhov sib txawv ntawm qhov sib txawv raws li qhov sib txawv ntawm cov diode rau qhov voltage, yog li tsis tas yuav tsum tau teeb tsa lub voltage divider resistor kom txo tau lub zog noj ntawm qhov no, tab sis cov zaub brightness thiab zaub. Cov nyhuv tsis cuam tshuam, thiab kev txuag hluav taws xob tau nce 25% ~ 40%.
Dab tsi yog qhov sib txawv ntawm tus tsav architecture ntawm cov cathode thiab ntau anode?
Ua ntej tshaj plaws, txoj kev tsav tsheb sib txawv. Kev tsav tsheb cathode feem ntau txhais tau hais tias tam sim no thawj zaug dhau los ntawm lub teeb hlaws thiab tom qab ntawd mus rau qhov tsis zoo electrode ntawm IC, yog li ntawd lub zog hluav taws xob rau pem hauv ntej yuav me dua thiab qhov kev tawm tsam yuav me dua. Cov tsav anode feem ntau yog tias tam sim no ntws los ntawm PCB pawg thawj coj saib mus rau lub teeb hlaws, uas muab lub zog rau lub nti sib npaug, thiab qhov hluav taws xob rau pem hauv ntej poob ntawm lub voj voog loj dua.
Thib ob, lub zog hluav taws xob hluav taws xob sib txawv, qhov sib txawv cathode tsav, qhov hluav taws xob ntawm cov nti liab yog li 2.8V, thiab qhov hluav taws xob ntawm cov xiav thiab ntsuab chips yog li 3.8V. Cov khoom siv hluav taws xob zoo no tuaj yeem ua tiav cov khoom siv hluav taws xob raug thiab siv hluav taws xob tsawg, thiab cov cua sov tsim los ntawm LED zaub thaum ua haujlwm. Kuj tseem tsawg. Common anode tsav, nyob rau hauv cov xwm txheej ntawm qhov tam sim no, qhov siab dua qhov hluav taws xob, lub zog siab dua, thiab ntau dua qhov kev siv hluav taws xob ntau dua. Nyob rau tib lub sijhawm, cov nti liab xav tau qhov hluav taws xob qis dua li cov xiav thiab ntsuab chips, yog li nws yog ib qho tsim nyog yuav tsum tau ua kom muaj qhov sib cais tsis sib haum nyob rau hauv siab, cov zaub coj los kuj tseem yuav ua rau muaj cua sov ntau dua thaum ua haujlwm.
SRYLED thev naus laus zis - lub pob zeb siab heev rau kev txhim kho ntawmmicro-pitch LED zaub
Qhov zoo ntawm COB thev naus laus zis nws tus kheej tau dhau los ua qhov tseem ceeb ntawm kev ua lag luam, thiab SRYLED COB tau tsa COB thev naus laus zis mus rau qhov siab tshiab. COB nws tus kheej yog ntau lub teeb sib xyaw ua ke-dawb ntim tshuab uas ncaj qha encapsulates lub teeb-emitting nti ntawm PCB board. Cov txheej txheem tedious nto mount raug tshem tawm, thiab tsis muaj qhov taw qhia ntawm lub bracket. LED nti thiab soldering hlau ntawm txhua pixel yog nruj thiab nruj nreem kaw nyob rau hauv lub colloid los ntawm epoxy resin, tsis muaj cov ntsiab lus. Rau kev tiv thaiv, nws tuaj yeem daws qhov teeb meem ntawm kev puas tsuaj rau pixels los ntawm lwm yam. SRYLED COB tuaj yeem ua kom qhov ceev tam sim no, txhim kho kev ruaj ntseg thiab lub teeb ua haujlwm ntawm cov hlaws dai, thiab SRYL qauv tuaj yeem ua tau raws li qhov xav tau. , Muaj kev ntseeg siab, thiab qhov zoo ntawm qhov tsis zoo ntawm qhov chaw teeb pom kev zoo los txhim kho kev ntseeg siab, ua kom yooj yim cov txheej txheem ntau lawm, thiab ua tiav cov txiaj ntsig zoo dua, uas tuaj yeem ua tiav nti-qib sib nrug thiab mus txog qib ntawm Micro LED.
COB qhov zoo li cas?
COB hla cov kev txwv ntawm kev ntim tshuab thiab ua rau lub suab me me. Peb tau tsim cov khoom lag luam nrog lub suab ntawm 0.6mm kom tau raws li qhov xav tau ntawm cov lus txhais siab 8K LED. Niaj hnub no, nws yog tsuas yog siv nyob rau hauv ntau lub chaw hais kom ua, cov ntaub ntawv chaw, studio centre, lub rooj sib tham chaw, chaw ua lag luam, tsev ua yeeb yam, thiab lwm yam. Nyob rau hauv lub neej yav tom ntej, nrog rau kev nce qib ntawm tiam tshiab technologies xws li 5G, Internet ntawm tej yam thiab dag. kev txawj ntse, nrog rau kev nrawm nrawm ntawm kev tsim kho cov ntaub ntawv xov xwm hauv tebchaws thiab kev hloov pauv hauv nroog cov ntaub ntawv xov xwm, kev lag luam khoom lag luam yuav txuas ntxiv txhim kho. , kev lom zem xov xwm thiab kev ruaj ntseg teb, kev lag luam kev cia siab yog qhov kaj heev. Nyob rau hauv lub neej yav tom ntej, cov khoom tso saib yuav txuas ntxiv txhim kho mus rau qhov chaw me me.
