Koj puas tuaj yeem kho lub pob tshab LED Screen?

Yog lawm. Tab sis qhov ntawd tsis yog lub ntsiab lus.

"Customization" nyob rau hauv lub pob tshab LED npo kev lag luam yog kev lag luam buzzword. Qhib ib lub chaw tsim khoom lub vev xaib, thiab koj yuav pom "kev kho kom haum xeeb muaj," "tsim raws li koj xav tau," "ib qho- nres kev pabcuam." Qhov no tsim ib qho kev xav tsis thoob: zoo li txhua yam duab, qhov loj me, lossis cov nyhuv xav tau tuaj yeem tsim tau.

90% ntawm yog li-hu ua "customization" tsuas yog modular los ua ke-mix thiab match.

Lub hauv paus ntawm lub pob tshab LED npo yog lub module- feem ntau cov qauv ntawm 500mm × 500mm los yog 1000mm × 500mm. 3m × 2m npo? Siv 6 modules thiab muab lawv ua ke . 5m × 3m? Ua ke 15.

Kev hloov kho tiag tiag-tsis yog- qauv qauv qhov ntau thiab tsawg, kev txiav tsis tu ncua, curvatures tshwj xeeb- feem ntau cov tuam ntxhab tsuas yog tsis xav ua, lossis lawv yuav hais tus nqi tsim los cuam tshuam kev lees paub. Vim li cas? Vim tias "customization" hauv kev tsim khoom txhais tau tias cov pwm tshiab, kev kho kab ntau lawm, kev tshuaj xyuas tus kheej zoo-txhua tus nqi. Thiab pob tshab LED npo margins twb raug nyem; manufacturers tsis muaj kev txhawb zog kom haum raws li cov kev cai tshwj xeeb.

Dab tsi "Customization" txhais tau tias (Yog li kev muag khoom tsis tuaj yeem thuam koj)

Loj -Customizable, tab sis nyob rau hauv ib daim phiaj

Pob tshab npo qhov ntau thiab tsawg yog cov lej sib npaug ntawm qhov ntau thiab tsawg. Cov qauv qhia tshwj xeeb: 500 × 500mm, 500 × 1000mm, 1000 × 500mm, 1000 × 1000mm . 3.5 meters dav? Puas tsis muaj nyob -nws yog 3 meters lossis 4 meters . 2.7 meters siab? 2.5 meters lossis 3 meters - xaiv ib qho.

Qee lub tuam txhab tuaj yeem ua "txiav modules" kom ua tiav qhov tsis yog{0}} qhov loj me, tab sis qhov no txhais tau tias PCBs kev cai, pwm tshiab, pib ntawm 30-50% tus nqi nce, thiab 2-4 lub lis piam ntev dua. Txawm nws tsim nyog nws yuav tsum tau muab xam.

Pixel Pitch-Qhov tseem ceeb xaiv

P3.9, P7.8, P10, P15, P20... Qhov ntsuas no ncaj qha txiav txim siab qhov sib npaug ntawm qhov pom tseeb, pob tshab, thiab tus nqi.

P3.9 ua haujlwm rau 3-6 meter saib, tau txais koj 55-65% pob tshab, tus nqi tshaj plaws. P7.8 suits 6-12 meters, pob tshab pob mus txog 65-75%, tus nqi nruab nrab. P10 yog rau 10+ meters tawm, 70-80% pob tshab, pheej yig dua. P15 thiab P20? Cov no yog rau billboards-15-30 meter saib nrug, 75-85% pob tshab, kev xaiv pheej yig tshaj.

Qhov me me pixel suab tsis yog ib txwm zoo dua -dab tsi zoo dua yog qhov sib tw saib qhov deb. Cov khw muag khoom atriums, sab nraum zoov kab hlau rhuav phab ntsa, kaw - qhov rais tso saib - qhov yuav tsum tau sib txawv kiag li.

Brightness -Qhov txawv loj ntawm sab hauv thiab sab nraum zoov

Kev siv sab hauv tsev: 800-2000 nits txaus. Sab nraum zoov lossis ncaj qha tshav ntuj: tsawg kawg yog 4000-6000 nits, txwv tsis pub tsis muaj dab tsi yuav pom thaum nruab hnub.

Brightness yog customizable, tab sis ntau dua brightness txhais tau hais tias ntau zog noj, ntau dua kub, ntau dua tus nqi. Nug cov chaw tsim khoom seb lawv puas tau hais "peak brightness" los yog "kev ua haujlwm ci ntsa iab"-qee cov tuam txhab hais txog qhov tseem ceeb tshaj plaws uas tsis tuaj yeem khaws cia thaum siv tas mus li.

Koj mount qhov no li cas?

Dai los ntawm sab saum toj ua haujlwm rau khw atriums thiab theem backdrops. Hauv av - sawv lossis stacking haum rau kev nthuav tawm ib ntus. Nto-mounted lossis embedded- txuas rau sab hauv ntawm cov iav kab hlau rhuav phab ntsa- yog daim ntawv thov kev tsim vaj tsev feem ntau. Kem-mounted nrog kev txhawb nqa kev ywj pheej ua haujlwm rau kev tshaj tawm sab nraum zoov.

Txoj kev txhim kho txiav txim siab txog kev saib xyuas module (kev saib xyuas pem hauv ntej lossis kev saib xyuas tom qab), xaiv cov khoom siv, thiab txawm tias tus qauv tsim ntawm cov modules lawv tus kheej. Qhov no yuav tsum tau txiav txim siab ua ntej xaj -tsis xam thaum lub sijhawm teeb tsa.

Pem hauv ntej tu los yog rear? Ua qhov no tsis ncaj ncees lawm thiab koj tab tom rhuav phab ntsa

Kev saib xyuas nraub qaum txhais tau tias tshem cov modules ntawm sab nraub qaum. Yuav tsum muaj tsawg kawg yog 50cm qhov chaw tom qab qhov screen. Tus nqi qis dua. Kev saib xyuas pem hauv ntej txhais tau hais tias tshem cov modules ntawm pem hauv ntej. Haum rau phab ntsa-mounted installations uas tsis muaj qhov chaw tom qab, ntau txoj kev module qauv, 10-20% tus nqi siab dua.

Xaiv txoj kev saib xyuas tsis raug, thiab tag nrho cov phab ntsa yuav tsum raug rhuav tshem los hloov ib qho module.

Tswj System-Tsis txhob xauv-in

Cov tuam txhab muaj npe nrov yuav muab kev xaiv: siv lawv cov kev tswj hwm tus kheej, lossis siv kev lag luam- cov qauv (NovaStar, Colorlight, Linsn).

Cov lus pom zoo: Xaiv lub tshuab thoob ntiaj teb. Proprietary systems yog shackles. Kev txhim kho yav tom ntej thiab kev saib xyuas yuav nyob ntawm lawv txoj kev hlub tshua.

Kev ntsuas tiv thaiv- Nyob ntawm qhov xwm txheej

Ib puag ncig qhuav hauv tsev: IP30-IP40 txaus. Sab hauv tsev av lossis dej vapor: IP54. Ib nrab- sab nraum zoov lossis tag nrho sab nraum zoov: IP65 lossis siab dua. Txhua qib nce hauv kev tiv thaiv kev ntsuas ntxiv 5-15% rau tus nqi. Tsis txhob over-engineer, tab sis tsis txhob underspec thiab muaj qhov screen ruined los ntawm dej.

Cov ntsiab lus tshwm sim - Kho tau tab sis txwv

Ncej xim (dub/dawb/nyiaj/grey), LED strip xim, lub hwj chim lub thawv txoj hauj lwm- feem ntau manufacturers tuaj yeem ua raws li cov no.

Tab sis kev cia siab yuav tsum txwv: LED nti xim, strip dav, module thickness -cov no yog standardized. Tshwj tsis yog tias qhov ntim loj txaus los ua pov thawj rau cov kab ntau lawm, tsis muaj kev hloov pauv.

Yog li -hu ua "customization" yog 80% hais txog kev sib xyaw ua ke hauv cov kev xaiv ruaj khov. Tau txais pixel suab, ci ntsa iab, qhov loj me, txoj kev teeb tsa, txoj kev tu, kev tswj hwm, thiab kev ntsuas kev tiv thaiv txoj cai- lub vijtsam yog kho kom haum- ua. Tau txais lawv yuam kev, thiab tsis muaj nyiaj siv rau "cov duab tshwj xeeb" yuav cawm nws. Qhov seem 20%? Txawm hais tias kim heev los yog tsis tau txais.

Lub Transparency Scam

Lub ntsiab muag ntawm pob tshab LED cov ntxaij vab tshaus yog "pob tshab." Tab sis qhov kev lag luam no daim ntawv lo ntawm pob tshab yog qhov tsis txaus ntseeg.

Thaum cov chaw tsim khoom hais tias 80% pob tshab, lawv tau txais tus lej li cas? Qee qhov ntsuas qhov sib piv ntawm qhov sib txawv ntawm LED strips rau tag nrho cheeb tsam -uas yog geometric pob tshab. Qee qhov ntsuas lub teeb xa hluav taws xob tiag tiag- uas yog qhov pom qhov pom tseeb. Qee qhov tsis suav nrog cov ncej, lub zog hluav taws xob, thiab cov kab hluav taws xob nkaus xwb, ntsuas tsuas yog thaj chaw pob tshab tshaj plaws. Qee tus txawm hais tias "theoretical transparency" uas cov khoom tiag tsis tuaj yeem ua tiav. Tsis muaj tus qauv sib koom ua ke- tus lej yog qhov twg tus neeg tsim khoom txiav txim siab.

High transparency txhais tau tias thinner LED strips, qhov sib txawv loj dua, tsawg dua LED chips. Tsawg LED chips txhais tau tias qis dua qhov ci, sparser pixels. Sawv ntsug 3 meters deb ntawm lub vijtsam P10 nrog 85% pob tshab, thiab cov duab tau tawg ua ke -pixels pom meej. Nws tsis yog "screen" tab sis kab ntawm glowing dots.

Yog li thaum lub chaw tsim khoom khav theeb "90% pob tshab," cov lus nug nug yog: pixel ceev yog dab tsi? Qhov tseeb brightness yog dab tsi? Qhov kev pom deb li cas? Yog tias cov no tsis qhia meej, kev khuv xim tom qab kos npe rau daim ntawv cog lus.

Ntau qhov kev ua tsis tiav yog los ntawm qhov tseeb: tus neeg siv khoom txaus siab los ntawm "siab pob tshab," tab sis tom qab kev teeb tsa pom cov ntsiab lus tsis pom thaum nruab hnub thiab tsaus ntuj heev thaum hmo ntuj. Pob tshab, yog-tab sis ib nrab ntawm lub vijtsam ua haujlwm tau puas lawm.

Tsis nco qab "Customization"-Pib nrog Saib nrug

Tsis yog obsessing tshaj "nws tuaj yeem hloov kho," xam ib yam: qhov pom qhov deb yog dab tsi? Qhov no txiav txim siab pixel suab. Pixel pitch txiav txim siab tus nqi, pob tshab, tso saib zoo - nws txiav txim siab yuav luag txhua yam.

Kev suav yog yooj yim: Yam tsawg kawg saib qhov nrug (meters) ≈ Pixel suab (millimeters)

Lub vijtsam P3.9 ua haujlwm zoo rau saib hauv 4 meters. Lub vijtsam P10 tsuas yog los ua ke ntawm 10+ meters deb. Lub vijtsam P20 yog tsim rau cov neeg saib ntau ntau ntawm cov meters deb. Xaiv qhov tsis ncaj ncees lawm pixel suab, thiab tsis muaj nyiaj yuav txuag nws.

Nov yog qee yam uas kuv tau pom dhau los: lub khw qhov rai qhia nrog P10 lossis txawm tias P16 pob tshab cov ntxaij vab tshaus, cov tswv yws yws txog cov txiaj ntsig tsis zoo. Qhov rai saib qhov deb tsuas yog 2-3 meters-P10 nrog pixels loj dua tus ntiv tes xoo ntsia, thiab xav tias yuav zoo li cas? Tab sis P10 yog pheej yig-txuag nyiaj, rhuav tshem cov nyhuv.

Lub ntsiab lus tseeb ntawm "kev cai" tsis muaj cov chaw tsim khoom tsim qee qhov txawv txav -zoo li lub vijtsam- nws tab tom nrhiav qhov sib npaug ntawm pixel suab, pob tshab, ci ntsa iab, thiab pob nyiaj siv uas haum rau qhov xwm txheej. Qhov no yuav tsum muaj kev txiav txim siab tshaj lij, tsis sau cov ntawv yuav tsum tau ua thiab tos rau cov lus hais.

Curved Screens Saib Amazing ntawm Trade Shows. Hauv Cov Haujlwm tiag tiag, Lawv yog npau suav phem.

Curved, cylindrical, yoj-zoo li tus, kheej kheej-cov no yog qhov muag tshaj plaws - ntes cov khoom ntawm kev nthuav qhia, thiab cov tuam txhab nyiam ua yeeb yam li lawv "kev muaj peev xwm kho tau."

Tab sis hauv cov haujlwm tiag tiag, cov ntxaij vab tshaus tsis tu ncua muaj qhov cuam tshuam ntau dua li cov ntxaij vab tshaus.

Tus nqi tsis nce linearly-lawv nce exponentially. Ib qho screen nkhaus ntawm tib cheeb tsam yuav raug nqi 2-3 npaug ntau npaum li lub vijtsam tiaj tus vim nws xav tau cov PCBs hloov tau yooj yim lossis cov qauv me me sib dhos, nrog cov nqi qis thiab cov txheej txheem nyuaj.

Curvature muaj kev txwv lub cev. Ib lub chaw tsim khoom yuav hais tias "peb tuaj yeem ua nkhaus," tab sis dab tsi yog qhov tsawg kawg nkaus khoov vojvoog? Qhov txwv rau cov khoom txheem yog nyob ib ncig ntawm 500-1000mm. Xav tau ib tug tighter nkhaus? LED chips yuav poob, PCBs yuav tawg.

Muaj lwm qhov teeb meem ntau tus neeg tsis xav txog: seams tau nthuav dav rau ntawm qhov chaw nkhaus. Module seams ntawm cov ntxaij vab tshaus tiaj tus tuaj yeem tswj tau ze li qhov pom ntawm qhov muag liab qab. Tab sis ntawm qhov chaw nkhaus, cov qauv sib ntsib ntawm cov ces kaum, ua rau cov seams pom tseeb -tshwj xeeb tshaj yog nyob rau hauv qhov tsaus ntuj, qhov twg pom cov kab dub tshwm.

Thiab tom qab ntawd muaj kev saib xyuas. Thaum ib qho module ua tsis tiav ntawm lub vijtsam tiaj, tshem nws, hloov nws - siv sijhawm feeb. Curved screen modules yog ua los ntawm cov ces kaum kev cai. Hloov ib qho yuav txhais tau tias tos rau cov chaw tsim khoom los tsim nws dua. Yuav ua li cas yog tias nws raug txiav lawm?

Cov ntxaij vab tshaus tsis xwm yeem tuaj yeem ua tau. Tab sis tshwj tsis yog tias qhov xwm txheej tiag tiag xav tau cov duab tsis zoo rau cov nyhuv, cov ntxaij vab tshaus tiaj tus yog qhov zoo dua. pheej yig dua, ruaj khov dua, yooj yim rau kev tswj.

Qhov nyiaj tiag mus qhov twg (Thiab qhov twg koj tau txais cim npe)

Nkag siab txog qhov kev lag luam no cov qauv nyiaj tau los qhia qhov twg lub cim npe nyob rau hauv quotes.

Tus nqi loj tshaj plaws ntawm pob tshab LED cov ntxaij vab tshaus yog LED nti, suav txog 30-40% ntawm tag nrho cov nqi. Chip manufacturers (Sanan, Changelight, Epistar) yog nyob rau hauv dej, nrog tag nrho cov paj ntawm 15-25% - cov nqi no kuj pob tshab.

Ntim -tig chips rau hauv cov hlaws LED- suav rau 15-20%. Cov tuam txhab xws li Nationstar thiab MLS tuav qhov no, nrog tag nrho cov nyiaj tau los ntawm 10-20%.

Qhov twg margins siab tshaj yog nyob rau hauv kev tsim tshuaj ntsuam thiab kev sib koom ua ke ntawm cov kab ke- cov paj tau paj tag nrho ntawm 20-40%. Qhov no kuj yog qhov uas feem ntau markup muaj.

Cov lus hais tau txais yuav tau dhau los ntawm 2-3 txheej los ntawm cov chaw tsim khoom mus rau cov neeg siv kawg: chaw tsim khoom → regional distributor → integrator → end user. Txhua txheej ntxiv 10-30%. Cov khoom qub dhau los ntawm cov kab sib txawv tuaj yeem sib txawv ntawm 50% ntawm tus nqi.

Kuj tseem muaj qhov zais qhov txiaj ntsig: kev tswj hwm. Ntau lub tuam txhab siv cov txheej txheem ua tswv cuab -ib zaug lawv lub vijtsam siv, lawv daim npav tswj hwm, lawv cov software, lawv cov kev txhawb nqa yuav tsum tau siv. Kev txij nkawm tom qab, hloov kho dua tshiab-Txawm li cas los xij lawv hais tus nqi, tsis muaj kev xaiv.

Yuav ua li cas kom tsis txhob pitfalls? Sim mus rau qhov chaw ncaj qha los ntawm kev tshuaj ntsuam manufacturers, hla tus neeg nruab nrab. Hais txog kev tswj hwm thoob ntiaj teb (NovaStar, Colorlight yog cov qauv kev lag luam)-tsis txhob raug kaw rau hauv cov txheej txheem muaj tswv. Sib piv tsawg kawg peb nqe lus- yog tias muaj qhov sib txawv ntawm tus nqi tseem ceeb rau tib qhov kev qhia tshwj xeeb, qee yam yuav tsum tau tshawb xyuas.

Lub vijtsam tsuas yog ib nrab tus nqi xwb. Tiag tiag.

Rau lub pob tshab LED npo, cov khoom nws tus kheej tsuas yog suav txog 50-60% ntawm tag nrho cov peev. Cov seem mus qhov twg?

Kev txhim kho thiab kev txhawb nqa.

Pob tshab cov ntxaij vab tshaus saib lub teeb thiab nyias, tab sis lawv tsis sib sib zog nqus -8-15 kg ib square meter. Lub 100-square-meter iav kab hlau rhuav phab ntsa nrog pob tshab cov ntxaij vab tshaus ntxiv ze li ib tuj ntawm cov khoom ntxiv. Cov ntaub thaiv phab ntsa uas twb muaj lawm puas tuaj yeem tuav nws? Nws puas xav tau kev txhawb nqa? Cov no tsis yog cov chaw tsim khoom lub luag haujlwm-lawv xav tau kev ntsuam xyuas tus kws tshaj lij engineers.

Hluav taws xob yog lwm qhov teeb meem. Transparent cov ntxaij vab tshaus noj 200-600 watts ib square meter. Ntawm 100 square meters, uas yog 20-60 kW. Puas yog qhov kev faib hluav taws xob tsim nyog? Puas yog cov kab hluav taws xob tshwj xeeb xav tau?

Yuav ua li cas yog thermal dissipation? LEDs ua kom sov, thiab iav ntaub thaiv phab ntsa tsis ua pa. Qhov chaw nruab nrab ntawm lub vijtsam thiab iav tau kub heev, tshwj xeeb tshaj yog nyob rau sab qab teb -facades nyob rau lub caij ntuj sov. Yog tsis hais txog cov cua kub dissipation, screen lifespan txom nyem heev.

Kev tsim kho kev sib koom tes kuj muaj teeb meem. Rau cov tsev tshiab, cov ntxaij vab tshaus pob tshab yuav tsum tau koom tes nrog cov ntaub thaiv phab ntsa tsim ua ntej. Rau kev kho dua tshiab, kev ua haujlwm sab nrauv façade yuav xav tau kev pom zoo. Cov tsev lag luam kuj yuav tsum xav txog seb kev tsim kho cuam tshuam li cas rau kev lag luam.

Qhov no yog qhov tseeb "customization"-tsis yog kho qhov screen, tab sis customizing ib qho kev daws teeb meem. Cov neeg tsim khoom lossis cov neeg koom ua ke uas xav txog tag nrho cov no yog cov uas muaj peev xwm xa khoom tiag. Cov neeg uas tsuas tham txog cov ntxaij vab tshaus yam tsis tham txog kev teeb tsa yog tos kom them nyiaj ntxiv tom qab lossis npaj yuav ploj tom qab xa khoom.

Kab hauv qab

Lo lus "customization" ua rau pob tshab LED cov ntxaij vab tshaus zoo li omnipotent. Tab sis qhov tseeb, qhov no yog cov khoom lag luam paub tab nrog kev paub meej ciam teb thiab cov qauv kev lag luam.

Cov tuam txhab lag luam tuaj yeem ua li cas yog pab nrhiav qhov kev teeb tsa zoo hauv cov txheej txheem tsim qauv. Dab tsi manufacturers ua tsis tau yog defy cov cai ntawm physics.

Es tsis yog nug "nws puas tuaj yeem kho tau," nug "qhov xav tau tiag tiag?" Txheeb xyuas qhov kev ncua deb, ambient brightness, installation tej yam kev mob, thiab nyiaj txiag txwv. Thaum cov kev txwv no tau txhais, qhov kev daws teeb meem zoo tshaj plaws tshwm sim. Tus so tsuas yog nrhiav ib lub tuam txhab txhim khu kev qha los ua nws.
