Xaiv ib qho LED zaub yuav tsum xav txog plaub yam tseem ceeb: daim ntawv thov scenario, pixel suab, pob nyiaj siv, thiab hom. Txoj kev xaiv tshwj xeeb yog raws li hauv qab no:
I. Kev txiav txim siab hom raws li daim ntawv thov scenario
Cov xwm txheej sab hauv tsev: Ua ntej cov qauv me me pixel suab kom pom tseeb. Rau qhov ze - qhov kev saib ntau yam xws li chav sib tham thiab cov khw muag khoom, P2.5 siab- rov qab los yog tus qauv- cov qauv tshiab tau pom zoo. Lub siab - refresh version yog tsim rau cov ntsiab lus dynamic zaub (xws li video playback), thaum tus qauv - refresh version yog tus nqi ntau dua - zoo; Yog tias xav tau kev tswj hwm tus nqi ntxiv, koj tuaj yeem xaiv P2.5 tus qauv- rov kho cov khoom tshiab los ntawm cov khoom lag luam xws li Haijia thiab Qangli Gaoke. Rau qhov ntev - saib qhov deb xws li cov khw muag khoom, P3 thiab P4 qauv tuaj yeem xaiv los txo tus nqi yuav khoom thaum ua kom pom tseeb.
Cov xwm txheej sab nrauv: P3 thiab P4 qauv yog cov kev xaiv tseem ceeb. Qhov loj dua pixel suab (xws li P4), tus nqi qis dua rau ib qho screen, ua rau nws tsim nyog rau qhov loj - thaj chaw teeb tsa; yog tias cov peev nyiaj txaus thiab xav tau kom pom tseeb dua, P3 qauv tuaj yeem xaiv. Cov xwm txheej sab nraum zoov xav tau kev saib xyuas ntxiv rau qhov kev tshuaj ntsuam dej tsis zoo thiab kev tiv thaiv lub hnub; Nws raug nquahu kom xaiv cov khoom siv nrog IP65 lossis siab dua tiv thaiv ntsuas.
II. Xaiv Pixel Pitch Raws li saib nrug
Kaw - saib ntau yam (1-5 meters): Cov qauv pixel me me yuav tsum raug xaiv, xws li P2.5 thiab hauv qab (P1.8, P2, thiab lwm yam). Qhov me me ntawm pixel suab, qhov siab dua qhov pixel ceev, thiab qhov tsis tshua pom ntawm cov npoo ntawm cov ntawv nyeem, ua rau nws tsim nyog rau kev nthuav tawm cov ntsiab lus zoo (xws li PPT kev nthuav qhia thiab cov duab siab txhais).
Qhov nruab nrab- saib ntau yam (5-15 meters): P3 qauv tuaj yeem siv tau, sib npaug ntawm qhov pom tseeb thiab tus nqi, tsim nyog rau lub khw muag khoom kos npe, theem backdrops, thiab lwm yam xwm txheej.
Ntev- saib ntau yam (15 meters thiab siab dua): P4 thiab cov qauv saum toj no txaus kom tau raws li qhov xav tau; me me pixel suab ntau dhau yuav yog qhov pov tseg ntawm cov peev txheej, tsim rau sab nraum zoov billboards, chaw ua si, thiab lwm yam xwm txheej.
Lub hauv paus ntsiab lus tseem ceeb: qhov me me ntawm pixel suab tus nqi, ntau pixels ntawm ib cheeb tsam, thiab qhov zoo ntawm cov duab pom, tab sis tus nqi nce exponentially. Qhov "tsawg kawg pom pixel suab" yuav tsum tau xam raws li qhov pom qhov deb. Cov mis yog: Yam tsawg kawg nkaus pixel pitch (mm) ≤ Saib nrug (m) × 0.85. Piv txwv li, rau qhov pom qhov deb ntawm 5 meters, lub pixel suab yuav tsum yog ≤ 4.25mm; Hauv qhov no, P3 (3mm) thiab P2.5 (2.5mm) ob leeg ua tau raws li qhov yuav tsum tau ua. III. Kev txiav txim siab hom Qib raws li kev siv nyiaj txiag
Cov peev nyiaj siab - kawg: Ua ntej cov hom lag luam xws li Leyard, Unilumin, Lanpu, thiab Lehman. Cov hom no muaj cov txiaj ntsig zoo hauv kev tsav tsheb chip, kev tsim cov xim, thiab kev tsim cov cua sov, ua rau lawv tsim nyog rau cov xwm txheej uas yuav tsum tau ua kom nruj (xws li TV studios thiab siab - chav sib tham kawg).
Nruab nrab - pob nyiaj siv: Cov hom muaj zog muaj qhov sib npaug ntawm kev ua tau zoo thiab tus nqi. Lawv cov khoom muaj cov ntsiab lus tseem ceeb xws li brightness uniformity thiab refresh npaum li cas uas nyob ze rau siab -end hom, tab sis ntawm 30% -50% tus nqi qis, tsim nyog rau cov tuam txhab showrooms thiab tsev kawm ntawv auditoriums.
Tsawg- cov nqi yuav tsum tau muaj: Hom zoo li Haijia thiab Gaoke muab cov khoom siv ua haujlwm yooj yim, tsim nyog rau kev siv nyiaj -cov xwm txheej txwv (xws li cov ntawv xov xwm hauv zej zog thiab cov xwm txheej ib ntus). Nco ntsoov tias cov khoom no tej zaum yuav muaj teeb meem xws li xim sib txawv thiab luv luv lifespan; nws raug pom zoo kom xav kom cov neeg muag khoom muab yam tsawg kawg 2 xyoo warranty.
IV. Ntsiab Parameter Verification
Refresh tus nqi: Dynamic duab zaub yuav tsum tau ≥3840Hz kom tsis txhob scanning kab; static zaub tuaj yeem so mus rau 1920Hz.
Brightness: Cov xwm txheej sab hauv tsev pom zoo 800-1500 cd / ㎡, cov xwm txheej sab nraum zoov xav tau ≥5000 cd / ㎡ los tiv thaiv lub teeb pom kev zoo.
Xim gamut kev pab them nqi: Ua ntej NTSC 90% lossis DCI-P3 xim gamut cov khoom lag luam kom muaj xim zoo dua qub.
Txoj kev tu: Pem hauv ntej txij nkawm tsim (magnetic modules) txuag chaw rau kev txij nkawm yav tom ntej, tsim nyog rau embedded installation scenarios.
V. Zam kev txhaum
Tsis txhob dhau - nrhiav qhov me me pixel suab: Txhua 1 hli txo cov pixel suab tuaj yeem nce nqi ntau dua 50%; xaiv rationally raws li saib nyob deb.
Ceev faj nrog tus nqi qis- nqi tsis paub npe: Qee cov khoom siv qis- cov khoom siv qis siv cov chips rov qab los yog cov kev daws teeb meem yooj yim, uas yuav ua rau cov pixels tuag, xim blocks, thiab lwm yam teeb meem, uas ua rau cov nqi kho mob siab.
Yuav tsum tau ntawm - qhov chaw kuaj: Xav kom cov neeg muab khoom muab cov qauv coj mus kuaj rau 24- teev tas mus li kev sim, tsom rau qhov qis-grayscale kev ua tau zoo (xws li, txawm tias grey kev hloov pauv yog ntuj) thiab kev ua haujlwm kub dissipation (txawm tias qhov ntsuas kub yog ≤45℃tom qab ua haujlwm ntev).
Los ntawm ua raws li plaub kauj ruam no - qhia meej txog kev siv qhov xwm txheej, xam qhov pom qhov deb, sib piv cov peev nyiaj, thiab txheeb xyuas qhov tseem ceeb tsis - koj tuaj yeem xaiv qhov tsim nyog tshaj plaws LED zaub daws teeb meem. Piv txwv li, yog tias ib lub tuam txhab yuav tsum tau nruab ib lub vijtsam hauv 20㎡ chav sib tham nrog kev pom qhov deb ntawm 3 meters thiab pob nyiaj siv ntawm 100,000 RMB, lawv yuav tsum xaiv lub siab -kev ua tau zoo P2.5 LED npo los ntawm lub npe nrov (pixel suab 2.5mm ≤ 3m × 0.85=2.55}mm, dynamic nqi raws li 80 Hz, refresh npaum li cas. 80,000 RMB, tawm 20,000 RMB rau kev teeb tsa thiab commissioning).
