Qhov Pitfalls Peb tau ntsib ntau xyoo: Tiag -Kev Sib Koom Ntiaj Teb ntawm Kev Txhim Kho thiab Kev Kho Vaj Tse
Nyob rau hauv tus txheej txheem ntawm kev xaiv, txhim kho, thiab tswj cov phab ntsa video, peb tau ntsib ntau yam kev cov nyom thiab muaj txiaj ntsig zoo. Cov hauv qab no yog qee cov lus qhia kom tsis txhob muaj qhov cuam tshuam los ntawm kev ua tau zoo, txhawm rau pab cov lag luam nrog kev yuav khoom xav tau kev xaiv ntau dua.
I. Tej Pitfalls hauv Video Phab Ntsa Xaiv
Blindly Pursuing Siab Brightness
Teeb meem: Ntau tus neeg muas zaub tau tsom ntau dhau ntawm qhov ci ntsa iab thaum yuav khoom, tsis quav ntsej qhov xav tau tiag tiag ntawm daim ntawv thov scenario.
Case Study: Qhov ci ntsa iab ntawm LED video phab ntsa hauv lub khw yuav siab dhau, ua rau tsis xis nyob rau cov neeg siv khoom.
Cov Lus Qhia Kom Zam Kev Tsis Txaus Siab: Xaiv qhov ci ntsa iab uas tsim nyog raws li kev siv ib puag ncig. Rau cov xwm txheej sab nraum zoov, xaiv cov ntxaij vab tshaus LED nrog lub ci ci ntawm 4000 nits lossis siab dua; rau cov xwm txheej sab hauv tsev, 700-1000 nits txaus.
Tsom ntsoov rau kev daws teeb meem nkaus xwb, tsis quav ntsej saib qhov deb
Teeb meem: tsom rau kev daws teeb meem nkaus xwb yam tsis xav txog qhov cuam tshuam ntawm kev pom kev deb ntawm qhov pom kev pom.
Case Study: Txawm hais tias qhov kev daws teeb meem ntawm lub vijtsam LED hauv qhov chaw ua haujlwm tsis siab, qhov pom ntawm qhov deb yog qhov zoo; lub siab - daws teeb meem LCD video phab ntsa hauv chav sib tham me me qhia kom meej meej.
Cov lus qhia kom tsis txhob muaj kev cuam tshuam ntau: Xaiv lub pixel pitch ntawm LED video phab ntsa lossis LCD video phab ntsa raws li qhov pom qhov deb. Rau qhov ntev - saib nyob deb, xaiv ib pixel suab ntawm P3 rau P4; rau ze- saib ntau yam, xaiv ib qho me me -pitch LED lossis LCD video phab ntsa.
Tsis quav ntsej Seams
Teeb meem: Seams nyob rau hauv LCD video phab ntsa cuam tshuam rau tag nrho cov zaub nyhuv.
Piv txwv li: Seams nyob rau hauv LCD video phab ntsa nyob rau hauv ib tug siab - kawg tsev noj mov banquet nrog tsis zoo rau kev zoo nkauj.
Cov lus qhia kom zam: Rau qhov xav tau siab heev ntawm cov duab seamless, xaiv ib qho me me -pitch LED video phab ntsa; Cov ntxaij vab tshaus LCD yog tsim rau cov duab zoo li qub lossis cov ntsiab lus segmented.
II. Tej teeb meem thiab kev paub hauv kev teeb tsa
Tsis quav ntsej txog kev ruaj ntseg ntawm cov qauv kev teeb tsa
Teeb meem: Kev ruaj ntseg thiab seismic tsis kam ntawm cov qauv kev txhawb nqa tsis tau txiav txim siab thaum lub sijhawm teeb tsa.
Piv txwv li: LED video phab ntsa nyob rau hauv ib lub chaw ntau pob tilted vim tsis tsim nyog kev txhawb nqa ncej tsim.
Cov lus qhia kom zam: Paub meej tias lub load-cov kabmob muaj peev xwm ntawm cov phab ntsa ntawm qhov chaw teeb tsa, xaiv ib pab neeg ua haujlwm tshaj lij, thiab xyuas kom muaj kev nyab xeeb thiab ruaj khov ntawm kev teeb tsa lub vijtsam.
Kev tswj tsis raug Cable
Teeb meem: Cov kab hluav taws xob ntev ntev, kev sib txuas xoob, lossis kev teeb tsa tsis sib haum ua rau cov teeb liab tsis ruaj khov.
Piv txwv li: Chaotic cable tswj nyob rau hauv ib qho chaw ua yeeb yam ua rau pom qhov txawv txav. Cov lus qhia kom tsis txhob muaj teeb meem tshwm sim: xyuas kom meej tias qhov ntev ntawm cable yog qhov tsim nyog, xaim yog huv, thiab siv electromagnetic shielding. Siv siab - zoo fiber ntau optic cables los yog shielded twisted -pair cables los txhim kho kev ruaj ntseg kis tau tus mob.
III. Common Maintenance Issues and Solutions
Tsis quav ntsej kev tshuaj ntsuam xyuas thiab tu
Teeb meem: Plua plav thiab av tsub zuj zuj cuam tshuam rau lub vijtsam tshav kub dissipation thiab tso saib kev ua haujlwm.
Piv txwv li: Sab nraum zoov LED advertising screen brightness poob vim tsis muaj kev tu.
Lub tswv yim kom zam: Ua tsis tu ncua tu thiab tu, them nyiaj tshwj xeeb rau plua plav, dej, thiab kev tiv thaiv av rau sab nraum zoov LED cov ntxaij vab tshaus. Tsis txhob siv cov tshuaj ntxuav tes uas muaj cawv lossis tshuaj rau cov ntxaij vab tshaus LCD.
Ua yuam kev yuam kev rau ib qho teeb meem, tsis quav ntsej txog qhov teeb meem ntawm qhov teeb meem
Teeb meem: Cov teeb meem pom tau feem ntau misdiagnosed raws li kev tshuaj ntsuam malfunctions, thaum nyob rau hauv qhov tseeb nws yog vim tsis raug teeb liab qhov kev twb kev txuas los yog configuration.
Piv txwv li: Flickering zaub ntawm lub tsev so video phab ntsa yog qhov tseeb vim qhov tsis ruaj khov HDMI teeb liab tso tawm los ntawm cov khoom siv playback.
Lub tswv yim kom zam: Tsis tu ncua xyuas qhov kev sib txuas ntawm cov khoom siv teeb liab kom ntseeg tau tias cov teeb liab kis tau zoo. Configure ntau lub teeb liab backup qhov khoom siv.
IV. Kev txhawj xeeb rau cov neeg yuav khoom thiab cov kws tshaj lij tawm tswv yim
LED vs LCD
Kev txhawj xeeb: Kev tsis sib haum xeeb ntawm qhov loj - thaj chaw tso saib xav tau thiab cov peev nyiaj tsawg.
Cov kws tshaj lij pom zoo: LED video phab ntsa rau loj - thaj chaw tso saib xws li kev tshaj tawm sab nraum zoov thiab chaw ua yeeb yam; LCD video phab ntsa rau cov ncauj lus kom ntxaws sab hauv tsev, xws li chav sib tham thiab chaw saib xyuas.
Ntsuas cov nqi pib nrog ntev -Cov nqi kho lub sijhawm
Qhov teeb meem: Tsom ntsoov rau cov nqi pib yuav khoom thaum tsis saib xyuas cov nqi kho mob tom ntej.
Cov kws tshaj lij cov lus qhia: Xav txog cov nqi yuav khoom nrog rau kev saib xyuas tom ntej, tu, hluav taws xob, thiab cov nqi hloov khoom seem thaum npaj koj cov peev nyiaj. Txawm hais tias LED cov ntxaij vab tshaus muaj cov nqi pib dua, lawv cov kav ntev thiab cov nqi kho qis ua rau lawv pheej yig dua nyob rau lub sijhawm ntev.
Xaus: Muaj ntau ntau yam yooj yim overlooked pitfalls nyob rau hauv kev xaiv, installation, thiab txij nkawm ntawm video phab ntsa. Los ntawm kev sau cov kev paub dhau los thiab cov ntaub ntawv tshawb fawb, peb tau muab cov lus qhia ntau ntxiv kom tsis txhob muaj cov teeb meem no, txhawm rau pab cov neeg yuav khoom xaiv kom paub ntau ntxiv. Txawm hais tias siv LED lossis LCD video phab ntsa, qhov kev txiav txim siab yuav tsum yog raws li qhov tseeb ntawm kev siv scenario, pob nyiaj siv, thiab kev xav tau kev saib xyuas tom ntej. Peb cia siab tias tsab xov xwm no tuaj yeem muab cov lus qhia zoo rau cov lag luam nrog cov kev xav tau ntawm phab ntsa video, kom ntseeg tau tias kev ua haujlwm zoo ntawm cov haujlwm.
