Cov duab social media tsis pom cov pixels lossis cov kab scan

Cov neeg tuaj koom tawm tswv yim: "Qhov pom tseeb tshaj plaws uas kuv tau pom dua"

Kev nyuaj siab dhau los:

Kev tswj cua sov:Cov zaub ua kom muaj cua sov tseem ceeb. Lub chaw HVAC tsis txaus - tus neeg koom ua ke tau ntxiv 12 cov kiv cua nqa tau tom qab cov zaub, txo qhov kub ntawm 52℃mus rau 38 degree.

Cov ntsiab lus compatibility:Qee tus neeg nthuav qhia tau xa cov ntsiab lus hauv kev daws teeb meem tsis raug. Cov zaub scaler hloov mus rau 4K seamlessly.

Lub koob yees duab synchronization:Tshaj tawm cov koob yees duab yuav tsum tau genlock synchronization. Cov zaub xa daim npav txhawb genlock input, tshem tawm cov teeb meem sync.

Cov lus qhia rau cov xwm txheej yav tom ntej:

Tshaj -spec brightness:2,000-nit zaub tau pom nyob rau hauv lub teeb ci ntsa iab. Rau cov xwm txheej yav tom ntej, qhia 2,500 nits rau ntau lub taub hau.

Kuaj cov ntsiab lus ua ntej qhov kev tshwm sim:10% ntawm cov neeg nthuav qhia xa cov ntsiab lus hauv 1080p es tsis yog 4K. Cov ntsiab lus upscaled saib tau tab sis tsis pom zoo. Lwm zaus, qhia cov ntsiab lus kom meej meej.

Muaj ib txoj kev npaj thaub qab:Pab neeg no muaj 5 lub txee seem ntawm -site. Thaum kuaj, ib lub txee ua tsis tiav - cov khoom seem tau hloov pauv hauv 15 feeb. Yog tsis muaj khoom seem, qhov kev tshwm sim yuav muaj qhov sib txawv pom.

Calibration tseem ceeb:Thawj qhov kev ntsuas lub Hoobkas tau ua tau zoo, tab sis ntawm - qhov chaw calibration ua rau nws zoo meej - tshwj xeeb tshaj yog rau cov tawv nqaij tones hauv kev nthuav qhia ze -ups. Cov peev nyiaj rau ntawm - site calibration hauv txhua qhov xwm txheej.

FAQ

Q1: Dab tsi yog qhov ua tau zoo tshaj plaws pixel pitch rau LED zaub?
A: Raws li xyoo 2026, qhov tsawg tshaj plaws kev lag luam muaj pixel suab yog P0.6 (0.6mm), siv nyob rau hauv siab -kawg cov khoom kim heev thiab cov chaw tsim khoom virtual. P0.6 muab 2.78 lab pixels ib square meter - dhau 4K daws teeb meem ntawm qhov ntau thiab tsawg. Txawm li cas los xij, P0.6 yog kim heev (tshaj $ 10,000 ib sq meter) thiab yuav tsum muaj kev txhim kho zoo meej (kub- tswj, vibration-dawb). Rau feem ntau cov ntawv thov, P1.2–P1.5 yog "qhov chaw qab zib" rau cov lus pom zoo, ntsuas kev daws teeb meem thiab tus nqi. Hauv qab P1.0, tus nqi nce exponentially yam tsis muaj qhov pom tau qhov txiaj ntsig tshwj tsis yog qhov pom qhov deb tsawg dua 3 feet.

Q2: Kuv yuav kuaj xyuas cov pixels tuag ntawm LED zaub li cas?
A: Khiav ib ntu ntawm tag nrho - qauv kuaj cov qauv: (1) Tag Nrho Dawb - txhua lub pixel tuag tshwm li cov xim dub; (2) Tag nrho liab - txhua pixel tsis muaj liab tshwm dub; (3) Tag nrho ntsuab - txhua pixel yam tsis muaj ntsuab tshwm dub; (4) Blue puv - txhua pixel tsis muaj xiav tshwm dub; (5) 50% grey – daig pixels (ib txwm nyob) tshwm li cov dots ci. Taug kev raws cov zaub ntawm qhov pom kev deb. Rau cov duab loj, siv lub koob yees duab nrog lub lens zoom los tshuaj xyuas cov ntu ntawm qhov deb. Qee lub tshuab kev tshaj lij tau tsim-hauv tus kheej- sim cov txheej txheem uas cia li qhia txog pixel tsis ua haujlwm. Feem ntau cov zaub tswj software suav nrog kev sim qauv tsim.

Q3: Puas tuaj yeem kho pixels, lossis kuv puas xav tau hloov tag nrho module?
A: Hauv 95% ntawm cov neeg mob, koj hloov tag nrho cov module. Kev kho tus kheej pixel yuav tsum tau: (1) Micro- cov khoom siv soldering (kub cua rework chaw nres tsheb); (2) Spare LEDs ntawm tib lub thawv thiab batch; (3) Tus kws kho mob nrog 100+ teev ntawm kev cob qhia; (4) 20-30 feeb ib pixel. Ntawm cov nqi ua haujlwm ib txwm ($ 100–200 / teev), kho 10 pixels nqi $ 300–600 - tib yam li cov qauv tshiab. Cov kev zam: (1) Siab-kawg COB qhia qhov twg modules tsis yog neeg siv{19}}serviceable (tsuas yog lub Hoobkas kho); (2) Cov khoom kim heev uas tus qauv tshiab raug nqi $1,000+; (3) Tub rog/aviation qhia nrog cov txheej txheem kho kom nruj. Rau feem ntau cov khoom lag luam thiab kev xauj tsev, kev hloov pauv module yog tus qauv thiab tus nqi feem ntau - txoj hauv kev zoo.

Q4: Pixel suab cuam tshuam li cas rau kev siv hluav taws xob?
A: Me me pixel suab txhais tau tias ntau pixels ib square meter - ntau LEDs, ntau tsav tsheb ICs, ntau zog. Piv txwv li: P10 muaj 10,000 pixels/m²; P1.2 muaj 694,000 pixels / m² - 69x ntau pixels. Txawm li cas los xij, txhua tusLED zaub pixelntawm qhov zoo -pitch zaub siv tsawg dua tam sim no ib pixel (LEDs me dua yuav tsum muaj zog tsawg). Net tshwm sim: P10 siv kwv yees li 500-800 W / m², P1.2 siv kwv yees li 200-400 W / m². Yog li cov suab me me tau siv lub zog tsawg dua ib square meter vim tias txhua pixel me dua thiab ua haujlwm zoo dua. Tag nrho lub zog siv nyob ntawm seb muaj pes tsawg pixels, tsis yog lub suab xwb.

Q5: Dab tsi yog qhov kev cia siab lifespan ntawm niaj hnub LED zaub pixel?
A: ZooLED zaub pixelCov tshuab raug ntsuas rau 100,000 teev rau 70% ci ntsa iab (L70). Thaum 24/7 ua haujlwm, qhov no yog 11.4 xyoo. Ntawm 12 teev / hnub (khoom muag), qhov no yog 22.8 xyoo. Txawm li cas los xij, lifespan nyob ntawm: (1)Ua haujlwm kub- txhua 10℃siab tshaj 25℃ib nrab lifespan; (2)Tam sim no- khiav ntawm tag nrho tam sim no (100%) txo txoj sia thiab khiav ntawm 70-80%; (3)Zoo- hwm LEDs los ntawm cov tuam txhab xws li Nichia, Cree, lossis Osram kav ntev dua li cov LEDs dav dav; (4)Ib puag ncig- av noo, plua plav, thiab kev vibration ua kom degradation. Rau cov ntawv thov tseem ceeb, pob nyiaj siv rau kev hloov pauv ntawm 70,000-80,000 teev (8-9 xyoo) es tsis yog qhov theoretical 100,000-teev txwv.
