Peb qhov sib txawv hauv kev xaiv qhov screen LED sab nraum zoov yog pixel pitch, module technology, thiab nti qib. Qhov txawv tshwj xeeb yog raws li nram no:
I. Pixel Pitch: Qhov tseem ceeb parameter txiav txim siab tus nqi thiab cov xwm txheej siv tau. Pixel pitch hais txog qhov kev ncua deb ntawm cov ntsiab lus hauv nruab nrab ntawm cov hlaws LED (unit: millimeters), cuam tshuam ncaj qha rau kev daws teeb meem, saib qhov deb, thiab tus nqi.
P10 (¥3k-4.5k/㎡)
Cov xwm txheej uas siv tau: Cov ntawv tshaj tawm hauv zej zog, ntev- cov ntaub ntawv qhia txog qhov deb (piv txwv li, saib ntawm 10 meters deb).
Nta: Tus nqi qis, tab sis pom pom pixelation ntawm qhov ze ("mosaic" nyhuv), haum rau cov xwm txheej uas muaj peev nyiaj tsawg thiab cov duab tsis zoo.
P6-P5 (¥6.5k-7k/㎡)
Cov xwm txheej uas siv tau: Cov chaw thauj mus los, cov ntxaij vab tshaus loj loj, nruab nrab -cov khoom lag luam nyob deb (xws li, saib ntawm 5-10 meters).
Nta: Tus nqi siab -kev ua tau zoo piv, ntsuas cov duab zoo thiab tus nqi, thawj qhov kev xaiv rau cov ntawv thov tseem ceeb.
P2.5 (¥6.8k+/㎡)
Cov xwm txheej uas siv tau: Siab- kawg lub khw muag khoom liab qab- lub qhov muag 3D cov ntxaij vab tshaus, kaw- ntau yam siab- cov lus txhais (xws li, saib hauv 5 meters).
Nta: Cov duab zoo nkauj, tab sis tus nqi siab dua; xav tau Micro LED thev naus laus zis (30% -50% kim dua li cov ntxaij vab tshaus ib txwm siv los ntawm 2025, tab sis txhim kho lub neej zoo thiab cov duab zoo).
Cov lus qhia zam:
Los ntawm 2025, P3 thiab qis dua micro- cov ntxaij vab tshaus pitch yuav muaj cov nqi nce ntxiv vim kev hloov kho thev naus laus zis, tab sis muab kev ua haujlwm ntev dua - nqi siv sijhawm- ua tau zoo.
Xaiv pixel pitch raws li qhov kev ncua deb: P6 / P8 rau kev saib ntau dua 10 meters, thiab hauv qab P3 rau kev saib hauv 5 meters.
II. Module Technology: Yam tseem ceeb cuam tshuam rau kev ua haujlwm ntev thiab kev siv hluav taws xob
Module thev naus laus zis txiav txim siab lub vijtsam LED lub peev xwm tiv thaiv, lub neej ntev, thiab cov nqi khiav lag luam; kev xaiv yuav tsum yog nyob ntawm qhov chaw siv.
SMD Surface Mount (Raws li tus nqi)
Nta: LEDs yog tsau siv tus txheej txheem nto mount; waterproofing cia siab rau sab nraud potting technology.
Cov xwm txheej tsim nyog: ib puag ncig qhuav, luv luv - siv sijhawm, lossis cov haujlwm uas muaj peev nyiaj tsawg.
COB Integrated (15% -30% Ntau Tus Nqi)
Nta: LEDs yog ncaj qha soldered mus rau lub rooj tsav xwm Circuit Court; muaj zog cuam tshuam tsis kam, 20% ntev lifespan, thiab siab waterproof thiab dustproof ntsuam xyuas.
Tsim nyog Scenarios: concerts, chaw tsim kho, thiab lwm yam siab -frequency los yog hnyav ib puag ncig.
Common Cathode Tsav Tsheb (10% Hwm)
Nta: Txo kev siv hluav taws xob los ntawm kev tswj hwm tam sim no, txuag kwv yees li 50% ntawm cov nqi hluav taws xob, tab sis cov nqi pib yog siab dua.
Cov xwm txheej tsim nyog:** Ntev- lub sijhawm ua haujlwm thiab lub zog- txuag cov xwm txheej (piv txwv li, 24-teev kev tshaj tawm cov ntxaij vab tshaus).
Cov lus pom zoo yuav khoom:
Hauv thaj chaw los nag, ua qhov tseem ceeb ntawm COB modules rau ya raws thiab poob tsis kam; xaiv cov tsav tsheb cathode rau cov xwm txheej uas nquag siv hluav taws xob lossis hluav taws xob - txuag cov kev xav tau; irregular designs (xws li, curved screens) yuav tsum tau hloov tau modules.
III. Chip Qib: Kev faib kab ntawm Brightness thiab Stability
Chip qib cuam tshuam ncaj qha rau qhov ci, tiv thaiv- muaj peev xwm attenuation, thiab tus nqi ntawm lub vijtsam LED, yuav tsum muaj kev lag luam tawm - tawm raws li kev xav tau siv.
Hauv Nruab Nrab -Range Chips
Brightness: 5000-8000 nits, ua tau raws li qhov xav tau ntawm cov ntxaij vab tshaus me me rau nruab nrab.
Nqe: Tus nqi siab -kev ua tau zoo piv, nrog rau kev lag luam feem ntau tshaj 70% los ntawm 2025, tab sis tseem cia siab rau kev ntshuam rau kev lag luam siab - kawg.
Tsim nyog Scenario: Kev tshaj tawm hauv zej zog, kev lag luam dav dav.
Imported High -End Chips
Brightness: Tshaj 12000 nits, muaj zog tiv thaiv -fading muaj peev xwm, ntev lifespan.
Nqe: 3 npaug kim dua li cov chips hauv tsev, tab sis nrog kev ruaj ntseg zoo dua.
Tsim nyog Scenarios: tshav dav hlau, landmark vaj tse, thiab lwm yam scenarios nrog heev brightness yuav tsum tau.
2025 Trends:
Cov cuab yeej siv hauv tsev tau maj mam loj hlob, tab sis lub siab -kawg lag luam tseem yog monopolized los ntawm cov khoom lag luam; Cov khoom me me thiab nruab nrab- cov phiaj xwm loj loj yuav tsum ua qhov tseem ceeb hauv cov chips rau cov nqi zoo dua -kev ua tau zoo; Rau cov tshav dav hlau, thaj chaw, thiab lwm yam xwm txheej uas muaj peev txheej txaus, cov chips tuaj yeem raug pom zoo kom ua kom ntev - lub sijhawm ruaj khov.
Summary : 2025 Screen Selection Guidelines
Kev ncua deb: Xaiv P6 / P8 tshaj 10 meters, P3 lossis qis dua hauv 5 meters;
Kev ncua deb: Xaiv COB rau cov dej nag, cov neeg tsav tsheb cathode rau cov hluav taws xob tsis tu ncua, hloov tau yooj yim rau cov qauv tsim tsis tu ncua;
Qhov deb: Cov chips hauv tsev rau cov khoom me thiab nruab nrab- cov hom loj, cov chips txawv teb chaws rau siab - kawg scenarios.
Los ntawm kev txhais kom meej cov kev xav tau thiab ntsuas qhov ntsuas thiab cov nqi, qhov kev daws teeb meem zoo tshaj plaws sab nraum zoov LED tuaj yeem xaiv tau zoo.
