I. Ntau lub LED modules tsis tu ncua tsis ua haujlwm lossis qhia qhov txawv txav: Xyuas seb lub ribbon cable thiab fais fab cable ntawm thawj qhov txawv txav ntawm lub teeb liab kev taw qhia tau txuas zoo. Yog tias tsis muaj LEDs teeb rau ntawm lub module, nws qhia tias tsis muaj lub zog nkag; thov xyuas cov khoom siv hluav taws xob (koj tuaj yeem siv multimeter los kuaj). Yog hais tias muaj xim distortions (random xim dots), nws qhia tias tsis muaj teeb liab nkag mus rau lub module; thov xyuas yog tias cov tswv yim kawg ntawm ribbon cable ntawm thawj qhov txawv txav yog nruj nreem txuas. Koj tuaj yeem sim ntsaws thiab tshem tawm nws ntau zaus. Yog tias qhov teeb meem tshwm sim, koj tuaj yeem hloov lub ribbon cable nrog ib qho tshiab.
II. Ib qho module tsis ua hauj lwm: Xyuas seb lub hwj huam mov rau lub module puas zoo, feem ntau xyuas seb lub hwj chim qhov hluav taws xob ntawm lub module yog xoob. Yog hais tias tag nrho cov module qhia cov xim distortion los yog cov xim tsis sib xws (tab sis muaj cov teeb liab tawm tswv yim thiab cov duab raug), nws qhia tau tias tsis zoo ntawm cov teeb liab kis tau tus mob ribbon cable. Re- ntsaws lub ribbon cable los yog hloov nrog ib qho kev sim. Yog hais tias qhov teeb meem tshwm sim tom qab hloov nrog ib tug zoo ribbon cable, thov xyuas seb puas muaj teeb meem nrog PCB board interface.
III. Ib leeg LED tsis ua hauj lwm nrhiav kom tau txoj kev: Siv ib tug multimeter los xyuas seb lub LED puas lawm. Yog tias LED tawg lawm, hloov nws raws li cov khoom tsib hauv qab no. Txoj kev ntsuas LED tshwj xeeb: Teem lub multimeter rau qhov tsis kam X1. Rau ib qho analog multimeter, txuas lub dub sojntsuam mus rau qhov zoo davhlau ya nyob twg LED thiab lub liab sojntsuam mus rau qhov tsis zoo davhlau ya nyob twg (rau ib tug digital multimeter, lub dub sojntsuam txuas mus rau qhov tsis zoo davhlau ya nyob twg thiab liab sojntsuam mus rau lub zoo davhlau ya nyob twg). Yog tias LED teeb pom kev zoo, qhov ntsuas LED tau zoo; Yog tias LED tsis teeb, qhov ntsuas LED tawg.
IV. LED tuag pixel txij nkawm (tsis tswj pixels): Tom qab ib zaug - teeb kuaj pom tseeb tias LED puas lawm, xaiv siv cov kev saib xyuas hauv qab no raws li qhov xav tau tiag tiag.
1. Kev saib xyuas pem hauv ntej: Siv lub hau ntswj ntawm tus qauv coj los tshem tawm cov ntsia hlau kho lub npog ntsej muag ntawm sab xub ntiag (nco ntsoov khaws cov ntsia hlau). Tshem lub npog ntsej muag thiab hloov lub LED (thov hloov lub LED raws li txoj kev hloov LED hauv qab no). Tom qab hloov lub LED thiab sealing nrog sealant, rov qab lub qub daim npog qhov ncauj thiab zawm cov screws (thaum zawm cov screws, thov ceev faj tsis txhob nias rau ntawm LEDs). Thaum kawg, yog tias muaj cov sealant residue ntawm LED nto, ua tib zoo tshem cov sealant. 2. Kev Kho Tsheb: Siv cov ntsia hlau sib txuas kom tshem cov ntsia hlau los ntawm sab nraub qaum (nco ntsoov khaws cov ntsia hlau kom zoo), txiav lub teeb liab cable. Txhawm rau kom muaj kev nyab xeeb, tsis txhob txiav lub hwj chim cable kom tsis txhob muaj xwm txheej. Ua tib zoo tshem lub module los ntawm cov ntawv hlau qhib thiab txav mus rau tom qab ntawm lub txee. Tom qab ntawd, ua raws li kev saib xyuas pem hauv ntej kom tswj lossis kho tus kheej modules (thov hloov cov LEDs raws li LED hloov txoj hauv qab).
V. LED Hloov: Tshem cov nplaum nyob ib ncig ntawm lub LED puas lawm nrog cov cuab yeej ntse (xws li tweezers), thiab xyuas kom meej tias cov pins LED pom meej meej. Tuav lub LED nrog tweezers nyob rau hauv koj sab tes xis, thiab siv ib tug soldering hlau (kub kwv yees li 40 degrees Celsius; siab kub yuav ua rau lub LED puas) kov lub solder, thiab tuav nws luv luv (tsis pub tshaj 3 vib nas this; yog hais tias nws tshaj lub sij hawm no tab sis lub LED tsis tau tshem tawm, cia nws txias thiab sim dua) kom yaj lub solder. Tshem cov LED nrog tweezers. Ntxig qhov tseeb LED rau hauv lub qhov ntawm PCB lub rooj tsavxwm (qhov ntev ntawm LED yog lub davhlau ya nyob twg zoo, thiab cov ceg luv yog lub davhlau ya nyob twg tsis zoo; lub "square qhov" ntawm PCB yog qhov zoo davhlau ya nyob twg tus pin qhov (socket), thiab "lub qhov" yog qhov tsis zoo ntawm lub davhlau ya nyob twg tus pin qhov (socket). Qhuav ib tug me me ntawm solder hlau thiab txuas mus rau lub soldering hlau taub. Kho cov kev taw qhia LED nrog tweezers kom nws ruaj khov, thiab solder lub LED mus rau PCB txuas taw tes. Foob lub LED nrog tib hom nplaum
.
Thaum lub sijhawm ua haujlwm sab nraum zoov puv -xim LED zaub, tus neeg ua haujlwm saib yuav tsum tau ua tib zoo saib xyuas, saib xyuas qhov txawv txav, tsw ntxhiab, lossis teeb pom kev zoo. Yog tias LED zaub tsis siv rau lub sijhawm ntev, nws yuav tsum tau kuaj xyuas ua ntej kom tsis muaj teeb meem ua ntej muab tso rau hauv. Nws yuav tsum tau muab sau tseg tias ntev -lub sij hawm disuse ntawm nto-mount LED zaub tuaj yeem ua rau txo qis kev ntseeg tau. Nws raug nquahu kom siv nws ntau tshaj li ob teev hauv ib lub lis piam kom txo qis kev puas tsuaj rau LED zaub.
