Yog vim li cas ntau lub lag luam hloov mus rau LED cov ntxaij vab tshaus
LED zaub tau dhau los ua ib qho pom hauv khw, khw noj mov, tsev so, thiab chaw ua yeeb yam. Nws yooj yim pom vim li cas. Lawv ci ntsa iab, hloov kho yooj yim, thiab kav ntev rau xyoo nrog kev saib xyuas me ntsis. Muab piv rau cov ntawv luam tawm lossis LCD vaj huam sib luag, lub vijtsam LED muab cov tswv lag luam yooj yim dua. Koj tuaj yeem hloov cov ntsiab lus txhua lub sijhawm, qhia cov yeeb yaj kiab lossis duab, thiab ua kom pom tseeb hauv qhov chaw tsis khoom.

Kauj Ruam 2: Nkag siab Pixel Pitch-Yog tsis muaj lus piav qhia
Pixel pitch tsuas yog qhov kev ncua deb ntawm lub teeb me me (pixels) ntawm qhov screen. Tus lej me txhais tau hais tias cov dots zaum ze ua ke, uas ua rau koj pom cov duab meej dua.
Nov yog ib txoj hauv kev yooj yim los xav txog nws:
Me pixel suab (hauv P3):Qhov zoo tshaj plaws rau kev saib ze, xws li hauv chav sib tham lossis lub khw muag khoom nyob ze ntawm lub txee.
Nruab nrab pixel suab (P4-P6):Zoo rau thaj chaw sab hauv tsev uas cov neeg sawv ntawm ob peb meters deb, zoo li lub chaw tos txais lossis ib qho chaw ua haujlwm.
Loj pixel suab (P8-P16 thiab siab dua):Zoo tagnrho rau sab nraum zoov billboards lossis chaw ntau pob cov ntxaij vab tshaus saib los ntawm qhov ntev.
Koj tsis xav tau qhov tsawg tshaj plaws pixel suab muaj. Koj tsuas yog xav tau qhov tsim nyog rau koj qhov kev ncua deb. Xaiv lub suab zoo dua li qhov koj xav tau nce nqi yam tsis tau txhim kho qhov kev paub rau koj cov neeg tuaj saib.
Kauj ruam 3: Xav txog txoj cai Screen Loj
Screen loj nyob ntawm ob yam: qhov chaw lub cev koj muaj, thiab deb npaum li cas koj cov neeg tuaj saib yuav sawv.
Ib txoj cai dav dav ntawm tus ntiv tes xoo yog tias qhov pom qhov tsawg kawg nkaus (hauv metres) yog kwv yees sib npaug ntawm tus nqi pixel pitch (hauv millimeters) muab faib los ntawm 3. Yog li lub vijtsam P4 ua haujlwm zoo los ntawm 12 meters deb.
Rau lub khw muag khoom me me, ib qho screen ntawm 2 thiab 6 square metres feem ntau ua haujlwm. Rau qhov loj loj sab nraum zoov billboard los yog ib theem kev hais kwv txhiaj, koj yuav xav tau ib yam dab tsi loj dua. Qhov xwm zoo yog tias cov ntxaij vab tshaus LED tuaj yeem tsim tau yuav luag txhua qhov loj vim tias cov panels txuas ua ke zoo li cov vuas.
Kauj ruam 4: Xav txog seb koj puas xav tau ib qho ruaj los yog xauj npo
Qee lub lag luam xav tau lub vijtsam uas nyob hauv ib qho chaw mus tas li. Lwm tus xav tau ib qho uas lawv tuaj yeem txav tau, teeb tsa, thiab tshem tawm rau cov xwm txheej sib txawv. Qhov ntawd yog qhov sib txawv tseem ceeb ntawm ataag LED zaubthiab axauj LED zaub.
Tsau cov ntxaij vab tshausyog tsim rau ntev - lub sij hawm installation. Lawv feem ntau tuaj nrog ib qho slimmer profile thiab tsim kom haum rau qhov zoo ntawm lub tsev lossis qhov chaw.
Xauv npoyog tsim los rau kev teeb tsa ceev thiab teardown. Lawv yog cov sib dua, rugged, thiab tsim los tswj kev thauj mus los. Cov tuam txhab kev tshwm sim, cov neeg txhawb nqa kev hais kwv txhiaj, thiab cov koom haum ua yeeb yam feem ntau nyiam hom no.
Xaiv cov qeb tsis raug tuaj yeem ua rau cov nqi tsis tsim nyog, yog li nws yuav pab kom paub meej tias koj npaj yuav siv lub vijtsam ua ntej koj yuav.
Kauj Ruam 5: Saib qhov ci ntsa iab thiab saib lub kaum sab xis
Qhov ci ci yog ntsuas hauv nits (cd / m²). Rau kev siv sab hauv tsev, ib qho screen ntawm 800 thiab 1,500 nits feem ntau yog txaus. Rau cov ntxaij vab tshaus sab nraum zoov nyob rau hauv tshav ntuj ncaj qha, koj feem ntau xav tau tsawg kawg yog 5,000 nits kom pom cov duab kom pom tseeb.
Saib lub kaum sab xis hais txog qhov dav ntawm qhov screen zoo li cas. Lub kaum sab xis pom dav dua txhais tau tias ntau tus neeg hauv chav tuaj yeem pom cov duab meej, txawm tias lawv sawv ntawm sab. Rau kev siv lag luam feem ntau, kab rov tav saib lub kaum sab xis ntawm 140 degrees lossis ntau dua npog feem ntau ntawm kev pom zoo.
Ob daim duab tshwm nyob rau hauv cov nplooj ntawv spec, thiab lawv tsim nyog kuaj ua ntej koj ua tiav kev yuav khoom.
Kauj Ruam 6: Npaj rau Ntev -Cov Nqi Them Sij Hawm
Tus nqi yuav khoom tsuas yog ib feem ntawm tag nrho cov nqi. Kev khiav cov nqi tseem ceeb heev.
LED cov ntxaij vab tshaus siv hluav taws xob, thiab lub vijtsam loj dua lossis ci ntsa iab rub lub zog ntau dua. Nug rau daim duab siv hluav taws xob (hauv watts ib square meter) thaum sib piv cov khoom. Cov qauv tshiab dua tshiab feem ntau siv lub zog tsawg dua li cov qauv qub thaum xa tib lub teeb ci.
Kev saib xyuas yog lwm yam. Qee cov ntxaij vab tshaus tso cai rau cov kws tshaj lij los hloov cov khoom siv tsis raug los ntawm sab xub ntiag, tsis tas txav lub vijtsam lossis tshem tawm cov ncej. Lub hauv ntej no - nkag mus rau tus qauv tsim tuaj yeem txuag tau ntau lub sijhawm thiab nyiaj txiag thoob plaws lub neej ntawm lub vijtsam. Yog tias koj lub vijtsam nkag mus rau hauv phab ntsa so lossis qhov chaw nruj, kev nkag rau pem hauv ntej yuav pab tau tshwj xeeb.
Ua Koj Qhov Kev Txiav Txim Kawg
