Sab Hauv Tsev LED Video Qhia 'Cov txiaj ntsig tseem ceeb
Nrog rau ntau qhov zoo ntawm cov projectors thiab LCD video phab ntsa, LED video zaub yog qhov kev xaiv zoo dua rau chav sib tham, chav ua yeeb yam, chaw tswj hwm, thiab cov chaw muag khoom.
Ua tiav seamless tiling: Cov duab txuas ntxiv thiab tsis cuam tshuam vim tsis muaj lub cev bezels ntawm cov modules. Daim duab qhia chaw, cov ntaub ntawv dashboards, thiab lwm yam khoom siv uas hla lub vaj huam sib luag ciam teb xav tau qhov no.
Glare- hloov qhov ci dawb: Cov vaj huam sib luag sab hauv tsev nrog nws pib- kev ntsuas lub peev xwm uas hloov kho rau lub teeb nyob ib puag ncig tuaj yeem txo mus rau 200–800 nits. Tsis zoo li cov projectors uas ua haujlwm tsis zoo hauv qhov chaw ci ntsa iab, qhov no lav qhov pom kev pom tseeb yam tsis ua rau qhov muag pom.
Ntau xim gamut thiab raug: Ntau qhov LED sab hauv tsev txhawb nqa DCI-P3, ua kom pom tseeb, xim tiag tiag tsim nyog rau siab -kev nthuav qhia kawg, kev kho mob, thiab kev ntsuam xyuas tsim.
Ultra-slim thiab qhov chaw-txuag: Lawv mount flush tiv thaiv phab ntsa nrog tag nrho cov tuab ntawm ob peb centimeters, txuag chaw hauv pem teb thiab muab qhov huv si, niaj hnub saib.
Cov ntsiab lus tseem ceeb ntawm LED Video Qhia Sab Hauv Tsev
Cov yam ntxwv tshwj xeeb ntawm sab hauv LED video tso saib teeb tsa lawv sib nrug los ntawm cov kev hloov pauv sab nraud thiab muaj kev cuam tshuam ncaj qha rau cov neeg siv kev paub.
Zoo pixel suab rau ze saib: Pitches zoo li P0.9, P1.2, los yog P1.5 yog qhov raug; ntawm saib qhov deb ntawm 2 mus rau 5 meters, lawv muab 4K- sib npaug sharpness uas tsis pom pixelation.
Tsawg brightness, zoo heev grayscale kev ua tau zoo: Cov ntxaij vab tshaus no khaws cov gradients du thiab duab ntxoov ntxoo cov ntsiab lus txawm nyob rau hauv qis brightness, uas yog ib qho tseem ceeb rau kev nthuav qhia los yog zaj duab xis ntsiab lus.
Kev ua haujlwm ntsiag to, tsis muaj kiv cua: Lub vijtsam ua haujlwm yuav luag ua tsaug rau qhov ua kom txias txias lossis ntuj tsim, ua rau nws zoo tagnrho rau kev tshaj tawm studios thiab thaj chaw sib tham.
Kev tswj hwm kev sib koom ua ke thiab kev sib txuas: Ntau tus qauv muaj wireless casting thiab kov- cov yam ntxwv sib cuam tshuam, thiab ua tau - hauv video processors tuav ntau yam khoom siv (HDMI, DP, thiab SDI) nrog kev sib hloov zoo.
Tsim Nyog Sab Hauv Tsev LED Video Qhia Kev Siv
Thaum txhim kho cov duab LED sab hauv tsev, ua raws li cov txheej txheem kws tshaj lij no kom tau txais cov duab zoo tshaj plaws thiab kev ruaj ntseg.
Xaiv qhov kev daws teeb meem raws li qhov pom qhov deb: P1.5 yog qhov txaus rau 1080p zoo ntawm qhov deb tshaj 2.5 meters. Txhawm rau kom tsis txhob pom ib tus pixels, xaiv P0.9 lossis me dua yog tias cov neeg saib ze dua 1.5 meters.
Ua kom muaj chaw rau kev saib xyuas: Rau sab nraub qaum- nkag mus, tawm qhov tsawg kawg ntawm 60 centimeters tom qab phab ntsa. Xaiv pem hauv ntej-cov kev tu vaj tse uas tuaj yeem tshem tawm ntawm sab saib yog tias qhov chaw txwv.
Teem lub teeb ci ntsa iab uas ua rau lub teeb ci ntsa iab tom qab kev teeb tsa kom phim qhov ci ntsa iab rau chav teeb pom kev zoo. Qhib lub auto-sensor los xyuas kom meej tias cov neeg saib yeej nyiam qhov screen.
Tsim cov ntsiab lus hauv cov qauv xim. Txhawm rau tiv thaiv cov xim hloov pauv los ntawm qhov tsis sib haum xeeb, siv Rec.709 lossis DCI-P3 thaum tsim cov ntaub ntawv.
Kev Ntsuas Kev Nyab Xeeb Tseem Ceeb rau LED Video Qhia Hauv Tsev
Cov tshuab hluav taws xob tsis zoo no tseem yuav tsum tau ua tib zoo saib xyuas, txawm tias qhov chaw nyob sab hauv tsev sov dua. Ua tib zoo saib xyuas cov xwm txheej no.
Thaum txhim kho lossis tu, yuav tsum hnav lub ntsej muag tiv thaiv- zoo li qub los tiv thaiv electrostatic paug (ESD). LED chips yuav raug ntaus los ntawm hluav taws xob zoo li qub, ua rau cov pixels tuag tas mus li.
Ua kom meej meej ntawm lub zog nquag caij tsheb kauj vab los ntawm tig nws ib zaug ib hnub thiab tawm hauv nws khiav. Nquag rau -Off cycles ua rau muaj kev ntxhov siab rau lub zog. Txhawm rau pib / nres, siv lub sijhawm teem sijhawm.
Kev sib npaug dawb li niaj zaus yog qhov tsim nyog vim tias ntau lub hnub nyoog ntawm cov nqi sib txawv. Txhawm rau tshem tawm cov xim hauv zos, ua ib qho dawb - ntsuas qhov sib npaug txhua rau lub hlis.
Tsis txhob siv cov cua txias ze ntawm lub vijtsam vim nws tuaj yeem tsim cov dej noo ntawm PCB thiab luv luv yog tias cua txias tuaj yeem ncaj qha mus rau lub vaj huam sib luag. AC vents yuav tsum nyob deb ntawm qhov chaw tso saib.
FAQ (3 nqe lus nug luv luv)
Q1: Dab tsi yog qhov txawv ntawm tus qauv TV los ntawm cov khoom siv sab hauv LED?
Ib qho kev tshaj lij, kev ua haujlwm zoo uas tuaj yeem ua kom zoo nkauj thiab kev cai - loj yog LED video zaub. Piv nrog rau cov neeg siv TVs, uas tau kho - qhov loj me thiab tsis yog - pobzeb, nws muab cov ci ntsa iab ntau dua, qhov dav xim gamut, thiab cov nqi rov qab sai dua.
Q2: Puas yog siab -pitch LED cov ntxaij vab tshaus xav tau ntau lub zog?
Tsis yog, sab hauv tsev variants siv tsawg-voltage common-cathode technology, uas tsuas yog siv 200–400 W/m², uas feem ntau tsawg dua li ntawm cov piv LCD video phab ntsa.
Q3: Yog tias ob peb pixels ua tsis tiav, kuv yuav ua li cas?
Feem ntau, ob peb lub pixels tuag tau zoo. Hu rau koj tus neeg muag khoom los hloov qhov cuam tshuam module yog tias lawv pawg lossis loj hlob (pem hauv ntej- qauv tu cia koj ua koj tus kheej).
