Koj tau xaiv qhov chaw, ntsuas phab ntsa, thiab teem ib pob nyiaj siv. Tom qab ntawd ib tus neeg nug cov lus nug uas txiav txim siab txhua yam: qhov kev daws teeb meem no yuav ua li cas rau LED video phab ntsa? Ntau dhau lawm, cov neeg yuav khoom pom cov lus teb tom qab kev teeb tsa - thaum lub logo zoo li ncab, cov ntawv nthuav dav tig plooj, thiab 4K footage ua si ntawm ib nrab ntawm nws qhov ntse. Kev ntxhov siab yog zam tau. Kev daws teeb meem ntawm phab ntsa LED video tsis yog qhov tshwj xeeb uas koj xaj tawm ntawm lub txee; nws yog qhov tshwm sim ntawm peb txoj kev xaiv ua haujlwm ua ke: pixel suab, qhov ntev ntawm lub cev, thiab qhov video. Tau txais txoj kev ua lej, thiab koj cov ntsiab lus zoo li tus thawj coj xav. Hauv phau ntawv qhia no, peb taug kev los ntawm tsib kauj ruam hauv cov lus yooj yooj yim, nrog cov qauv, rooj, thiab cov piv txwv uas koj xav tau ua ntej kos npe rau daim ntawv xaj.
Kauj ruam 1: Nkag siab tias "Kev daws teeb meem" txhais li cas ntawm lub vijtsam LED
Tsis zoo li TV lossis saib, LED zaub tsis muaj kev daws teeb meem ib txwm muaj kom txog thaum koj tsim ib qho ntawm cov txee. Txhua lub txee nqa ib lub pixel matrix ruaj khov, thiab qhov kawg pixel suav tsuas yog:
Tag nrho pixels=(phab ntsa dav ÷ suab) × (phab ntsa qhov siab ÷ suab).
Nov yog piv txwv ceev. A 5 m × 3 m phab ntsa ua los ntawm P2.5 cov khoom xa tawm 2,000 × 1,200 pixels - ze rau Full HD. Sib pauv hauv P5 txee ntawm qhov loj me, thiab koj tau txais 1,000 × 600, kwv yees li 1/4 ntawm pixel suav.
Peb cov ntsiab lus ua raws li qhov no:
- Pixel suab tsav txhua yam.Cov suab me me txhais tau tias ntau pixels ib square meter, ntawm tus nqi siab dua.
- Lub cev loj yog koj lub zog thib ob.Ib phab ntsa loj ntawm tib lub suab ib txwm tau txais kev daws teeb meem ib txwm muaj.
- Cov ntsiab lus yuav tsum phim lub pixel grid ..LED phab ntsa upscale los yog downscale txawm koj xa lawv, yog li ib tug mismatch tshwm sim li plooj, distortion, los yog moiré.
Kauj ruam 2: Sib phim Pixel Pitch rau Saib nrug
Txoj cai kev lag luam ntawm tus ntiv tes xoo yog qhov yooj yim: tus saib nrog lub zeem muag tsis pom qhov txawv ntawm tus kheej pixels ntawm kwv yees1 meter rau 1 mm ntawm lub suab. Hauv lwm lo lus, lub vijtsam P2.5 zoo li seamless los ntawm kwv yees li 2.5 m deb, thaum P10 billboard xav tau 10 m lossis ntau dua.
| Pixel suab | Yam tsawg kawg yooj yim saib nyob deb | Tej daim ntawv thov |
|---|---|---|
| P1.2–P1.5 | 1.2–1.5 m | Boardrooms, broadcast studios, command centers |
| P2–P2.5 | 2–2.5 m | khw muag khoom showrooms, chav sib tham, TV studios |
| P3–P4 | 3–4 m | theem backdrops, koom haum lobby, me me txheej xwm |
| P5–P6.7 | 5–6.7 m | theem xauj tsev, concerts screens, exhibition halls |
| P8–P10 | 8–10 m | sab nraum zoov billboards, stadium perimeter boards |
Daim ntawv ceeb toom yuav ua li cas lub vev xaib lub cev ua feem ntau ntawm kev txiav txim siab rau koj. Sab hauv phab ntsa pom los ntawm thoob plaws lub chaw tos txais ua rau lub suab coarser; tswj-chav video phab ntsa saib ntawm caj npab ntev tsis tuaj yeem. Ua ntej koj poob rau hauv kev hlub nrog tus nqi, taug kev qhov tseeb pom thiab ntsuas qhov twg tus neeg saib ze tshaj plaws yuav sawv.
Kauj Ruam 3: Xam cov kev daws teeb meem haiv neeg los ntawm koj phab ntsa loj
Thaum lub suab thiab qhov ntev tau txiav txim siab, suav cov phiaj xwm pixel ib txwm - thiab xyuas nws tawm tsam koj cov ntsiab lus. Cov txee ntau qhov ntau thiab tsawg (500 × 500 mm, 500 × 1000 mm rau kev xauj; 640 × 480 mm, 960 × 960 mm rau kev ruaj khov) txhua tus nqa cov pixel suav ib lub vaj huam sib luag.
Ua hauj lwm los ntawm cov ntaub ntawv xauj tsev tiag tiag:
- Phab ntsa loj:6 m × 3.5 m
- Suab:P3.91(500 × 500 hli, 128 × 128 pixels txhua)
- Native daws teeb meem:12 × 7 txee=1, 536 × 896 pixels
Tam sim no sib piv rau koj cov ntaub ntawv program. Lub 1080p highlight reel (1920 × 1080) yuav tsum ntsws kom haum; tus processor tuav nws, tab sis cov ntawv zoo softens. A 16: 9-native 4K pub poob qis li 65% ntawm nws cov pixels. Lub caij no, kev cai tsim 1536 × 896 animation plays pixel-zoo meej nrog xoom scaling. Qhov no yog vim li cas tshaj tawm cov studios thiab XR theem insist ntawm lub suab zoo - lawv xav tau daim phiaj kom tau raws li lawv lub koob yees duab, tsis yog lwm txoj hauv kev.
Kev kuaj xyuas tus kheej sai:Yog tias koj cov ntsiab lus tseem ceeb yog 16: 9, tsim phab ntsa ntawm qhov tseeb 16: 9 nam piv. Piv txwv li: 4.0 × 2.25 m, 6.4 × 3.6 m, los yog txee ntau ntawm 16 × 9 panels. Nws tsis raug nqi dab tsi ntawm lub sijhawm tsim thiab txuag lub sijhawm kawg ntawm lub processor taub hau tom qab.
Kauj ruam 4: Sib phim cov Video Source Thiab Npaj Cov Txheej Txheem Txheej Txheem
Cov kev txiav txim siab yuav los tom ntej. Hauv kev xyaum koj yuav ntsib plaub qhov xwm txheej:
- Ib leeg-neeg uas ua ntawv cov ntsiab lus (ads, menus, loops).Nug koj pab neeg cov ntsiab lus los tsim cov animation ntawm qhov kev daws teeb meem ib txwm muaj. Loop nws los ntawm tus txheej txheem media player - tsis muaj scaling, tsis muaj artifacts.
- Tsau lub koob yees duab / UHD pub (tshaj tawm, kis las).Xaiv lub suab thiab phab ntsa piv uas tuav 1080p lossis 4K ib txwm muaj, tom qab ntawd pob nyiaj siv rau cov khoom siv siab bandwidth nrog HDMI 2.0 / 12G-SDI inputs.
- Ntau qhov chaw sib xyaw (cov rooj sib tham, chav tswj).Npaj cov txheej txheem video nrog cov ntawv nkag txaus thiab lub peev xwm windowing; txhua lub qhov rais teev nws tus kheej, yog li overscan margins tseem ceeb.
- Distributed/edge-blended shows.Sib phim tus processor's pixel daim ntawv qhia rau lub txee tswj lub sijhawm tsim, tsis yog tom qab xa khoom.
Ob tus nqi ntxiab tsim nyog tau hais txog ntawm no. Ua ntej, qee cov txheej txheem pheej yig yeej cov lus hais los ntawm kev xa mus rau 30 Hz ua haujlwm lossis 8-ntsis xim, uas ntsiag to degrades greyscale thiab kev ua haujlwm ntawm lub koob yees duab. Qhov thib ob, ultra-wide los yog tsis-tus qauv nam piv feem ntau xav tau kev cai-mapped cov ntsiab lus; pob nyiaj siv rau qhov rov sau dua ua ntej qhov screen nkoj, vim hais tias cov ntsiab lus retrofitting tom qab tus nqi ntau dua.
Kauj ruam 5: Siv tau nrog cov ntsiab lus tiag ua ntej koj kos npe
Cov ntawv muag khoom qhia koj tias lub vijtsam tuaj yeem ua tau dab tsi; cov duab tiag qhia koj seb nws yuav zoo li cas. Ua ntej cog lus, khiav daim ntawv pov thawj:
- Nqa koj tus kheej ntsuas ntsuas- cov yeeb yaj kiab tiag tiag, UI dashboards, lossis lub koob yees duab pub, tsis yog cov khoom siv dav dav.
- Xyuas cov ntawv nyeem tau yooj yimntawm qhov ze tshaj qhov pom qhov deb; cov ntawv me tsis ua ntej ntawm cov lus ntxhib.
- Tshawb xyuas kab pheeb ces kaum hloov- panning txhaj tshuaj thiab scrolling tickers qhia cov duab kos duab uas zoo li qub zais.
- Paub meej tias processor settings(brightness, xim kub, scan configuration) phim cov demo tej yam kev mob uas koj yuav khiav hauv ntau lawm.
Kev sim kaum tsib feeb nrog cov khoom siv tseeb tiv thaiv kev yuav khoom uas yuav khiav mus rau kaum xyoo. Txhua lub tuam txhab muaj npe nrov yuav tsum txais tos nws; yog tias ib tug tsis kam, kho qhov ntawd raws li cov ntaub ntawv tseem ceeb.
Xaus thiab Kauj Ruam Tom ntej
Sizing LED video phab ntsa daws teeb meem yog lej lej, tsis yog twv ua haujlwm. Txhim kho qhov pom kev deb ua ntej, xaiv lub suab uas tshem tawm nws, cia cov phab ntsa qhov ntev txheeb xyuas koj cov pixel suav, tom qab ntawd kho cov duab video thiab cov txheej txheem rau daim phiaj - thiab ua pov thawj nrog cov ntsiab lus tiag ua ntej xa khoom. Ua tsib yam no, thiab ncab lub logo, daim duab tsis pom kev, thiab qhov sib piv tsis sib haum tsis txhob ua rau koj phab ntsa.
