"Vim li cas ib tus neeg muag khoom hais txog 800persquaremeterwhileanotherasksfor800 ib square meter thaum lwm tus nug txog 800persquaremeterwhileanotherasksfor2,400 rau qhov zoo li tib lub vijtsam?" Yog tias koj tau thov LED cov lus hais los ntawm ntau lub chaw tsim khoom, koj twb paub qhov kev ntxhov siab: ntawm daim ntawv, ob lub tswv yim tuaj yeem hais tias "P3.9 sab nraum zoov tsau LED video phab ntsa," tab sis tus nqi sib txawv ntawm peb zaug. Qhov txawv yog nyob rau hauv xya tus nqi tsav tsheb uas feem ntau cov lus zais tom qab cov nplooj ntawv spec tsis meej. Ntxiv mus, nkag siab txog cov tsav tsheb no hloov koj los ntawm tus nqi - tus neeg siv khoom mus rau tus neeg yuav khoom muaj kev ntseeg siab. Yog li, phau ntawv qhia no nthuav tawm txhua yam hauv cov lus yooj yooj yim, tom qab ntawd muab cov lus qhia txog nyiaj txiag tiag tiag uas koj tuaj yeem siv ua ntej koj qhov kev nug tom ntej.
1. Pixel Pitch: Tus nqi loj tshaj plaws
Pixel pitch - qhov kev ncua deb ntawm LED chaw, ntsuas hauv millimeters - yog tus nqi sib txawv loj tshaj plaws. Hauv cov ntsiab lus yooj yim, ib nrab ntawm lub suab kwv yees li plaub npaug ntawm cov pob LED ib square meter, uas nce nqi khoom, tus tsav tsheb IC suav, thiab lub sijhawm tsim khoom.
Piv txwv li:
- P16 sab nraum zoov billboard:mature technology, tsawg heev Cheebtsam, tus nqi qis tshaj ib m².
- P6.67 / P5 sab nraum zoov tsau:qhov chaw qab zib rau 20-100 m² billboards saib los ntawm 20 m deb.
- P2.5 thiab hauv qab no (hauv tsev):txhua lub suab qis tuaj yeem ntxiv 30-80% rau tus nqi.
Yog li ntawd, lo lus nug tiag tiag tsis yog "lub suab twg yog qhov pheej yig tshaj" tab sis "lub suab twg phim kuv qhov kev pom deb." P3.9 npo saib los ntawm 30 meters nkim koj cov peev nyiaj; P1.5 npo saib los ntawm 10 meters yog lub suab peev.
2. Screen Size: Kho qhov siab, ces sib tham qhov dav
Qhov loj me yuav siv ob zaug. Ua ntej, cov ntxaij vab tshaus loj dua nyiam cov nqi qis dua vim tias cov khoom siv hluav taws xob thiab cov cuab yeej siv tau thoob plaws ntau square meters. Qhov thib ob, thiab qhov tseem ceeb tshaj, qhov siab - rau - txee piv tsim cov khib nyiab.
Feem ntau lub Hoobkas khoom tuaj hauv cov qauv ruaj (feem ntau 960 × 960 mm rau sab nraum zoov lossis 640 × 480 mm rau sab hauv). Yog li ntawd, yog tias koj npaj 6 m × 4 m screen quab yuam tsis yog -txheej txheem txee, seem nqi nce thiab yog li koj tus nqi.
Tswv yim tswv yim:es tsis kho qhov dav dav, nug tus neeg muag khoom uas suav cov txee (xws li 6 × 3, 8 × 4, 12 × 5 txee) yog pheej yig dua. Peb tau pom cov neeg siv khoom txuag 8-12% txoj kev no los ntawm kev kho qhov dav ib nrab ib 'meter' xwb.
3. Brightness thiab Application Ib puag ncig
Cov kev xav tau ci ntsa iab txawv txawv ntawm cov xwm txheej, thiab yog li ua tus nqi:
| Daim ntawv thov | Hom Brightness | Tus nqi cuam tshuam |
|---|---|---|
| Sab hauv tsev ruaj (chaw tos txais, chav sib tham) | 600-1,000 nits | Lub hauv paus |
| Sab hauv tsev xauj / theem | 1,000-1,500 nits | me ntsis nce; siab refresh ntxiv ntxiv |
| Sab nraum zoov tsau (advertising) | 5,500-10,000 nits | Qhov tseem ceeb; tsav teeb, daim npog qhov ncauj, thiab cov nqi cua txias |
| Tsheb / chaw ntau pob | 6, 000+ nits nrog dav saib lub kaum ntse ntse | Cov khoom siv tshwj xeeb |
Qhov tseem ceeb, ib qho screen sab nraum zoov ntsuas ntawm 10,000 nits tsis tuaj yeem tsuas yog qhov ci ntsa iab sab hauv tsev; nws xav tau cua sov- tiv taus LED ntim, zoo dua thermal tsim, thiab pem hauv ntej - tu lossis rear- kev pabcuam qauv - txhua qhov ntxiv tus nqi tiag tiag uas "tib yam ci ntsa iab, tus nqi qis" feem ntau ntsiag to tshem tawm.
4. Cov khoom siv txee thiab cov qauv
Ntawm no yog qhov twg quotes diverge feem ntau aggressively:
Tuag-cast aluminium:lub teeb, corrosion-resistant, zoo tagnrho rau kev xauj tsev thiab nkhaus tsim; tus nqi siab dua, tus nqi thauj khoom qis dua.
Txias-rolled steel:pheej yig tshaj rau sab nraum zoov tsau, tab sis hnyav dua ntawm koj cov qauv steel.
Profile aluminium welded:ib qho chaw nruab nrab rau cov ntawv loj loj.
Tsis tas li ntawd, txawm tias lub vijtsam yog pem hauv ntej - khaws cia lossis tom qab - tseem ceeb. Kev pab cuam tom qab txuag nyiaj ua ntej tab sis xav tau 0.8-1 m ntawm txoj kev nkag mus tom qab phab ntsa - thiab hauv nroog kev teeb tsa (khoom noj khoom haus facades, tsev tawv nqaij), txoj kev hauv tsev tsuas tsis muaj nyob. Pem hauv ntej-tus qauv tsim kho tus nqi me ntsis ntxiv rau ib lub txee tsis tau nquag txuag tag nrho qhov project.
5. Tswj System, Fais Fab, thiab Cov Khoom Siv
Cov lus hais uas tsuas yog sau "tswj daim npav suav nrog" tsim nyog xav tsis thoob. Qhov tseeb, cov tshuab tswj tau muaj peb theem:
- Synchronous daim card- zoo rau ib qho screen offline.
- Synchronous txais daim npav system (Novastar-chav kawm).- tsim nyog rau cov phab ntsa video, splicing, thiab multi-window playback.
- Asynchronous / huab- tswj tau (4G, tej thaj chaw deb tshaj tawm).- qhov tseem ceeb rau daim ntawv tshaj tawm hauv cov nroog deb uas tus kws tshaj lij tuaj yeem tuaj xyuas txhua lub lim tiam.
Ntxiv rau qhov ntawd, qhov tseem ceeb hauv cov khoom siv hluav taws xob (feem ntau- cathode zog- txuag tsav txiav kev siv txog li 40-50%, them rov qab cov nqi them rov qab hauv ib xyoos siab- siv), cabling, rooj sib tham davhlau (qis), thiab cov qauv hlau tshwj xeeb. Kev lag luam kev paub qhia cov khoom siv thiab cov qauv feem ntau ntxiv 15-25% rau saum cov nqi vaj huam sib luag.
6. Kev teeb tsa, Qhov chaw nyob, thiab cov lej hauv zos
Ob lub vijtsam nrog cov specs zoo ib yam tuaj yeem nqa cov nqi sib txawv vim yog phab ntsa tom qab lawv:
- Phab ntsa-mounted vs. dawb-nce ncej:ib lub hauv paus ncej hauv cua- thaj chaw tej yam kev mob tuaj yeem raug nqi ntau dua li cov vaj huam sib luag.
- Qhov siab thiab crane nkag:siab tshaj 10 m, rigging teev multiply.
- Kev ua raws li hluav taws xob hauv zos thiab kev nyab xeeb:Hauv EU, Middle East, thiab North America, qee cov neeg siv khoom ntsib cov kev soj ntsuam ntawm cov qauv sab nraud.
Yog li ntawd, ib txwm thov ib qho kev teeb tsa uas sib cais: steel qauv, kev ua haujlwm, nqa, thiab commissioning. Nkaum bundling ntawm no yog qhov classic qhov chaw uas "pheej yig vaj huam sib luag, kim project" tshwm sim.
7. Tom qab-Kev Txhawb Kev Muag Khoom: Tus Nqi Tsis Pom
Thaum kawg, tus nqi pheej yig tshaj plaws feem ntau dhau los ua tus nqi kim tshaj plaws. Xav txog dab tsi ib tug PCB tuag los yog ib qho tsis tau txais daim npav tus nqi dhau 5-xyoo lub neej: lub tsev khaws khoom tso tawm offline rau ob lub lis piam thaum koj lub caij nyoog siab tshaj plaws, lossis qhov phem dua, DOOH daim ntawv tshaj tawm tsaus ntuj thaum lub sijhawm tshaj tawm daim ntawv cog lus.
Ntsuam xyuas kev txhawb nqa ntawm plaub lub ntsiab lus: spare-qhov piv nrog nrog rau thawj cov khoom xa tuaj (tus qauv yog 1–3%), module lossis txee- qib hloov tsis yog tag nrho- npo rov qab, muaj peev xwm kuaj xyuas thaj chaw deb, thiab firmware/software upgrade cog lus. Lub Hoobkas nrog cov ntaub ntawv pov thawj txoj cai thiab 24-teev cov lus teb yeej tus nqi pob zeb-hauv qab hauv tag nrho cov nqi ntawm cov tswv cuab ze li txhua zaus.
Kev siv nyiaj tiag tiag (2026)
| Hom npo | Hom Pitch | Qhov taw qhia Tus Nqi Ntau (USD / m², panels + tswj) |
|---|---|---|
| Sab nraum zoov tsau billboard | P6.67–P10 | 400–400–400–900 |
| Sab nraum zoov kho, pem hauv ntej-kev tu, lub zog- txuag | P4–P6.67 | 800–800–800–1,600 |
| Nyob sab hauv tsev tsau zoo suab | P1.5–P2.5 | 1,200–1,200–1,200–2,800 |
| Sab hauv tsev xauj / theem | P2.6–P3.9 | 900–900–900–1,800 |
| Pob tshab mesh / muaj tswv yim | Kev cai | 1,500–1,500–1,500–4,000 |
Qhov ntau yog qhia; Qhov tseeb quotes txawv nrog brightness, IC qib, ntawv pov thawj, thiab txiav txim ntim.
Peb lo lus nug uas tiv thaiv koj cov peev nyiaj
Ua ntej koj sib piv cov lus hais ib sab, nug txhua tus neeg muag khoom:
Lub pob LED twg (SMD / COB / GOB), lub teeb hom twg, thiab tus tsav IC qib twg suav nrog ntawm tus nqi no?
Peak vs. nruab nrab fais fab noj npaum li cas ib m² - thiab puas yog lub tswv yim tsav cathode?
Dab tsi yog suav nrog hauv tus nqi: cov khoom seem, cov qauv tsim qauv kos duab, kev taw qhia kev teeb tsa, thiab cov lus lav?
Ib tus neeg muag khoom tsis kam teb peb cov lus nug hauv kev sau ntawv yog sib tw ntawm opacity, tsis muaj nqi.
Xaus
Hauv luv luv, kev cai LED npo tus nqi tsis yog ib tus lej; nws yog qhov suav ntawm lub suab, qhov loj, qhov ci, qauv, kev tswj, kev teeb tsa, thiab kev txhawb nqa. Vim tias xya yam sib cuam tshuam, qhov zoo tshaj plaws kev yuav khoom yog kaw koj qhov kev ncua deb thiab daim ntawv thov ua ntej, thiab tom qab ntawd cia tus kws tsim khoom tsim cov lus qhia nyob ib puag ncig lawv. Thaum koj npaj txhij los hloov cov peev nyiaj rau hauv kev tsim, xa peb qhov project qhov chaw, lub hom phiaj loj, saib qhov deb, thiab cov ntsiab lus hom - Litestar's engineering team yuav teb tsis pub dhau 24 teev nrog kev teeb tsa, cov lus qhia meej, thiab kev txhawb nqa kev ua neej nyob.
