Yuav ua li cas LED Zaub Tswj Systems Ua Haujlwm tiag tiag: Kev Ua Haujlwm Zoo rau txhua tus xav paub txog thev naus laus zis

Nyob zoo txhua leej txhua tus, yog tias koj tau saib ntawm qhov loj heev sab nraum zoov LED daim ntawv tshaj tawm flashing kev tshaj tawm, lossis saib lub rooj sib tham theem teeb nrog siv lead ua -cov phab ntsa video ntshiab, tej zaum koj yuav xav tsis thoob: LED zaub tswj qhov system ua tau li cas? Nws tsis yog khawv koob-nws yog kev sib xyaw ntse ntawm cov khoom siv kho vajtse, software, thiab qee qhov ntse engineering uas hloov cov ntaub ntawv nyoos rau hauv cov duab zoo nkauj.

Niaj hnub no, peb tab tom nkag mus tob rau hauv LED zaub tswj cov tshuab- lawv yog dab tsi, lawv tsim tau li cas, cov thev naus laus zis tseem ceeb koom nrog, thiab vim li cas lawv tseem ceeb hauv lub ntiaj teb digital signage niaj hnub no. Peb yuav khaws nws ncaj nraim, zoo li peb tab tom tham kas fes, tab sis ntim nrog cov ntsiab lus tiag. Thiab txij li peb pab neeg ntawm Minghua Display tshwj xeeb hauv kev cai LCD zaub (xav tias cov ntxaij vab tshaus tsim rau kev lag luam, kev kho mob, lossis kev siv lag luam), peb yuav kov cov ntsiab cai no sib tshooj nrog LCD thev naus laus zis ib yam nkaus -vim qee zaum qhov kev daws teeb meem zoo tshaj plaws tsis yog LED txhua.

Cia peb pib ntawm qhov pib.

Ntawm nws qhov tseem ceeb, LED zaub tswj qhov system (qee zaus hu ua LED maub los, daim npav tswj, lossis tsuas yog "lub hlwb" ntawm lub vijtsam) yog cov khoom siv thiab software combo uas siv koj cov ntsiab lus -cov duab, yeeb yaj kiab, ntawv nyeem- thiab ua kom txhua tus LED pixel teeb pom kev raws sijhawm, nrog rau qhov kaj thiab xim.

Xav txog nws li no: LEDs lawv tus kheej tsuas yog lub teeb me me hauv daim phiaj loj. Tsis muaj kev tswj hwm, lawv tsis muaj txiaj ntsig. Lub kaw lus tswj tau txais cov teeb liab (los ntawm lub computer, media player, lossis txawm tias nyob pub), ua haujlwm rau lawv, khw muag khoom yog tias xav tau, thiab tom qab ntawd tsav cov LEDs kab los ntawm kab lossis hauv arrays los tsim cov duab.

Niaj hnub nimno systems poob rau hauv ob pawg loj:

• Synchronous tswj: Real-time, zoo meej rau cov xwm txheej nyob, concerts, lossis txhua yam uas xav tau xoom ncua. Nws tsom rua qhov uas nyob ntawm koj lub computer screen raws nraim.
• Asynchronous tswj: Offline hom- upload cov ntsiab lus ib zaug (xws li kev tshaj tawm lossis cov sijhawm teem sijhawm), thiab nws ua si ntawm nws tus kheej. Zoo heev rau billboards, khw muag khoom kos npe, lossis info boards.

Los ntawm qhov peb tau pom hauv kev lag luam (thiab los ntawm tons ntawm kev tshawb fawb tib neeg ua zoo li "LED zaub tswj qhov system nws ua haujlwm li cas"), feem ntau cov neeg xav paub txog kev tsim vaj tsev: cov ntaub ntawv ntws los ntawm cov tswv yim rau pixel.

Ib tug raug LED zaub tswj qhov system muaj cov ntsiab lus tseem ceeb ua haujlwm ua ke:

1. Cov ntsiab lus Source- Koj lub PC, laptop, video processor, lossis txawm tias huab server.
    
2. Xa daim npav / Transmitter- Nyob ze ntawm qhov chaw. Nws tuav lub teeb liab video (HDMI, DVI, DP, thiab lwm yam), ua rau nws, thiab xa nws hla cov cables ntev (feem ntau Ethernet lossis fiber ntau) rau cov zaub.
    
3. Txais Daim Npav- Ib (lossis ntau dua) rau ib lub txee/module hauv LED npo. Cov no txiav txim siab cov ntaub ntawv, qhia nws rau cov pixels tshwj xeeb, tswj qhov ci / grey nplai, thiab xa cov teeb liab tsav mus rau LEDs.
    
4. LED tsav ICs- Cov chips txoj cai ntawm cov modules tswj tam sim no rau txhua lub LED rau xim thiab ci ntsa iab (PWM rau greyscale yog ntau).
    
5. Cov Khoom Siv Hluav Taws Xob & Cable- Lub zog ruaj khov thiab huv cov ntaub ntawv kab- tseem ceeb heev kom tsis txhob flickering lossis hloov xim.
    
6. Tswj Software- Tus neeg siv -ib feem phooj ywg. Cov kev pab cuam cia koj kho cov ntsiab lus, teem caij playlists, kho qhov ci raws li lub teeb nyob ib puag ncig, lossis tseem saib xyuas lub vijtsam nyob deb.
    

Cov ntaub ntawv ntws ncaj nraim: Cov tswv yim → Kev ua haujlwm (scaling, kho xim) → Kis → Distribution to receive cards → Pixel-level drive → Light up!

Rau kev teeb tsa me me, zoo li cov ntawv cim, koj tsuas yog muaj daim npav tswj hwm yooj yim nrog USB / SD daim npav nkag. Rau cov phab ntsa video loj, nws yog tag nrho synchronous systems nrog video processors tuav 4K lossis siab dua.

Ib qho ntawm qhov txias tshaj plaws (thiab feem ntau tshawb nrhiav) yog cov qauv scanning. LEDs tsis ci tag nrho ib zaug - nws yog lub zog dhau - tshaib plab. Hloov chaw, peb luam cov kab lossis kab nrawm nrawm.

• Static scanning(1/1): Txhua pixel tau txais kev tswj ncaj qha. Qhov zoo tshaj plaws ci thiab zoo, tab sis kim rau cov ntxaij vab tshaus loj.
   
• Dynamic scanning(xws li 1/8, 1/16, 1/32): Teeb ntau kab hauv ib ntus ceev ceev (ntau pua zaus hauv ib ob). Txuag lub zog thiab tus nqi, tab sis tuaj yeem ua rau qhov ci ntsa iab me ntsis yog tias tsis ua tiav.
   

Niaj hnub no "array" los yog faib tswj (vs qub centralized) boosts refresh tus nqi mus rau 120Hz+, greyscale rau 1024+ qib, thiab txiav fais fab poob ntau heev -los ntawm 30-40% nyob rau hauv qub systems rau 8-10% tam sim no. Qhov ntawd txhais tau tias cov ntxaij vab tshaus ci dua lossis qis dua cov nqi hluav taws xob-kev txuag tiag tiag rau kev teeb tsa loj.

Piv txwv li, nyob rau sab nraum zoov loj puv -xim npo, hloov mus rau array-style tswj yuav txuag tau 20%+ ntawm lub zog. Peb tau tsoo cov lej zoo sib xws rau cov neeg siv khoom, thiab nws ntxiv nrawm dua xyoo.

Cov neeg tshawb nrhiav "LED zaub tswj cov txheej txheem" ​​feem ntau ntaus rau cov kev hloov kho tshiab no:

• High refresh & greyscale- Tsis muaj flicker, du video, muaj tseeb-rau- lub neej xim.
• Tib -pixel nrhiav & calibration- Nws pib- kuaj pom cov LEDs tuag, lossis kho qhov ci / xim hloov raws sijhawm (LEDs muaj hnub nyoog sib txawv-xiav ploj sai tshaj).
• Zog-txuag tech- Kev soj ntsuam zoo dua txhais tau tias tsis muaj pov tseg tam sim no.
• LVDS lossis siab - kis tau tus mob ceev- Txo cov teeb liab poob ntawm qhov deb, ua kom txhua yam sib txuas nrog tsis muaj xim thaiv.

Software sab: Kho cov cuab yeej cia koj kos duab, ntaus ntawv, ntxiv cov teebmeem (scroll, flash), saib ua ntej, thiab batch- upload ntau lub vijtsam. Wireless lossis serial comms (RS232/485) tuav uploads hauv cov laus; tam sim no nws feem ntau Ethernet/WiFi/cloud.

Ntawm no yog qhov uas nws tau nthuav. Thaum LED txoj cai loj sab nraum zoov / qhov chaw tshaj tawm (siab ci ntsa iab, qhov loj me), LCD tseem tseem nyob sab hauv tsev -xav kiosks, kho mob saib xyuas, muaj HMIs, lossis taw tes- ntawm - muag khoom. LCD muab pixel ceev zoo dua, zoo ib yam backlighting, thiab feem ntau txo nqi rau me me - rau - qhov nruab nrab qhov loj me.

NtawmMinghua Display, peb tshwj xeeb hauv kev cai LCD zaub -los ntawm me me 2.8 "UART modules mus rau loj siab - brightness panels nrog capacitive kov. Xav tau lub hnub ci-TFT LCD nyeem tau? Peb kho qhov ci ci, cuam tshuam (MIPI, LVDS, RGB), npog iav, lossis txawm tias tag nrho cov rooj sib tham nrog PCAP kov.

• Tsis zoo li tawm ntawm-- cov khoom txee, peb txoj kev cai txhais tau tias:
• Qhov loj me thiab kev daws teeb meem kom haum rau koj qhov chaw nyob.
• Customized interfaces (UART rau kev tswj MCU yooj yim, lossis HDMI rau video).
• Cov kev kho mob tshwj xeeb: tiv thaiv- glare, waterproof, dav temp range.
• Prototyping ceev ceev-qee zaum hauv hnub.

Yog tias koj qhov project cuam tshuam nrog cov ntaub ntawv qhia, dashboards, lossis cov kab ke kos, ib qho kev cai LCD los ntawm peb yuav ua tau zoo tshaj qhov kev teeb tsa LED hauv lub zog, pom tseeb, lossis kev koom ua ke.

Peb tau pab cov neeg siv khoom hauv kev kho mob, tsheb, thiab khw muag khoom sib pauv rau cov khoom siv LCDs thiab txiav cov nqi thaum txhawb kev ntseeg siab.

Txawm hais tias nws yog LED lossis LCD, qhov kev tswj hwm yog dab tsi tig ib pawg ntawm pixels rau hauv ib yam dab tsi tseem ceeb. Rau LED, nws yog txhua yam hais txog kev soj ntsuam ceev ceev, siab refresh, thiab kev tsav tsheb ua haujlwm tau zoo los daws cov kev daws teeb meem loj yam tsis muaj cov khoom siv hluav taws xob yaj.

Cov thev naus laus zis tau los ntev heev-Tuam Tshoj tam sim no ua rau kev tsim khoom thoob ntiaj teb, tab sis kev tsim kho tshiab tseem thawb ciam teb (Mini / Micro LED leej twg?).

Yog tias koj tab tom tsim ib qhov project thiab khawb koj lub taub hau hla LED zaub tswj cov tshuab lossis xav tias cov kev cai LCD zaub yuav zoo dua, xa peb kab ntawm Minghua Display. Peb zoo siab los tham txog specs, xa cov qauv, lossis tawm tswv yim txog koj cov kev xav tau tiag tiag.
