Raws li tus neeg muag khoom ntawm LED cov lus qhia rau cov tsev teev ntuj nrog ntau cov ntaub ntawv tshawb fawb, kuv nkag siab txog qhov yuav tsum tau muajLED zaubuas ua tau raws li qhov xav tau ntawm pawg ntseeg thaum tseem muab kev pom zoo. Hauv blog no, kuv yuav qhia qee cov lus qhia txog yuav ua li cas xaiv qhov zoo tshaj plaws LED zaub los pab coj qee qhov kev kwv yees tawm ntawm kev xaiv LED zaub rau koj pawg ntseeg.
2. Paub Koj Cov Kev Xav Tau
Ua ntej, peb yuav tsum txheeb xyuas cov kev xav tau tshwj xeeb ntawm pawg ntseeg. Qhov luaj li cas ntawm lub tsev teev ntuj thiab saib qhov deb ntawm cov neeg tuaj saib yog qhov tseem ceeb hauv kev txiav txim siab txog hom LED zaub. Peb yuav tsum xav txog qhov chaw zaum ntawm lub tsev teev ntuj, saib qhov deb ntawm cov neeg tuaj saib, thiab seb peb puas xav tau cov khoom siv sab nraum zoov. Kev nkag siab txog cov kev xav tau no tuaj yeem pab peb txo peb txoj kev xaiv.
3. Cov neeg saib xyuas qhov deb
Hauv cov tsev teev ntuj loj, koj yuav tsum xyuas kom meej tias cov neeg tuaj saib nyob rau hauv kab rov qab tuaj yeem pom meej tias yog dab tsi ntawm qhov screen. Yog hais tias lub tsev teev ntuj me me, yuav tsum muaj ib qho screen saib ze dua. Feem ntau hais lus, qhov kev ncua deb ntawm koj qhov kev pom yog, qhov siab dua qhov loj thiab kev daws teeb meem ntawm qhov screen xav tau.
Cov tsev teev ntuj me me(tsawg dua 100 tus neeg): qhov pom kev deb yog li 5-10 metres, thiab koj tuaj yeem xaiv P3 lossis siab dua lub tsev teev ntuj LED zaub.
Lub tsev teev ntuj nruab nrab(100-300 tus neeg): qhov kev pom zoo tshaj plaws yog li 10-20 metres, nws raug nquahu kom xaiv P2.5-P3 daws teeb meem pawg ntseeg LED zaub.
Lub tsev teev ntuj loj(ntau tshaj 300 tus neeg): qhov kev pom zoo tshaj plaws yog ntau tshaj 20 metres, P2 lossis siab dua kev daws teeb meem hauv tsev teev ntuj LED zaub yog qhov zoo tagnrho.
4. Qhov loj ntawm qhov chaw
Koj yuav tsum xam qhov chaw nyob hauv lub tsev teev ntuj kom txiav txim siab qhov screen loj. Qhov no tsis yog qhov nyuaj. Qhov loj ntawm lub tsev teev ntuj LED zaub yuav tsum ua kom haum rau qhov chaw tiag tiag ntawm pawg ntseeg, loj dhau lossis me dhau yuav cuam tshuam rau kev pom.RTLEDtseem tuaj yeem muab cov kev daws teeb meem zoo tshaj plaws LED rau koj lub tsev teev ntuj.
5. Xaiv qhov kev daws teeb meem zoo
Kev daws teeb meem yog ib qho tseem ceeb hauv kev xaivlub tsev teev ntuj LED zaub, xaiv txoj kev daws teeb meem raws li koj qhov kev siv scenario.
P2, P3, P4: Cov no yog lub tsev teev ntuj LED teeb pom kev daws teeb meem, tus lej tsawg dua, qhov kev daws teeb meem siab dua, qhov pom tseeb dua. Rau cov tsev teev ntuj me me, P3 lossis siab dua daws teeb meem tuaj yeem muab cov duab meej dua.
Fine Pitch LED Zaub: Yog tias lub tsev teev ntuj cov peev nyiaj tso cai, lub suab me me LED zaub (xws li P1.5 lossis P2) tuaj yeem muab qhov kev daws teeb meem siab dua thiab cov lus qhia ntxaws ntxiv, zoo tagnrho rau lub sijhawm uas cov duab zoo lossis cov ntawv tso tawm.
Kev sib raug zoo ntawm kev pom qhov deb thiab kev daws teeb meem: Feem ntau hais lus, qhov ze qhov pom qhov deb, qhov kev daws teeb meem siab dua yuav tsum yog. Qhov no tuaj yeem suav tau raws li cov qauv hauv qab no:
Optimal Saib Distance (meters) = Pixel Pitch (millimeters) x 1000 / 0.3
Piv txwv li, qhov pom kev ncua deb ntawm P3 zaub yog kwv yees li 10 meters.
6. Brightness thiab zoo sib xws
Qhov ci ntsa iab thiab qhov sib txawv yog qhov tseem ceeb cuam tshuam rau cov teeb pom kev zoo ntawm lub tsev teev ntuj LED zaub.
Brightness: Feem ntau muaj lub teeb qis hauv lub tsev teev ntuj, yog li nws yog ib qho tseem ceeb uas yuav tsum xaiv lub tsev teev ntuj LED npo nrog qhov ci nruab nrab. Yog hais tias lub tsev teev ntuj muaj ntau lub teeb ntuj, tej zaum peb yuav xav tau ib lub teeb ci dua. Feem ntau, sab hauv LED zaub yog nyob nruab nrab ntawm 800-1500 nits, thaum sab nraum zoov yuav tsum tau ci dua.
Contrast: Lub tsev teev ntuj siab sib txawv LED zaub muab cov xim zoo nkauj dua thiab cov xim dub tob dua, ua rau cov duab zoo dua. Xaiv ib qho screen nrog qhov sib piv siab zoo tuaj yeem txhim kho tus neeg pom qhov pom.
7. Txoj kev teeb tsa
Kev teeb tsa: Cov txheej txheem sib txawv (xws li phab ntsa-mounted, tshem tawm, thiab lwm yam) tuaj yeem xaiv raws li cov xwm txheej tshwj xeeb ntawm pawg ntseeg.
Phab ntsa-mounted installation: Tsim nyog rau cov tsev teev ntuj uas muaj phab ntsa dav thiab siab rau cov neeg tuaj saib. Phab ntsa-mounted installation tuaj yeem txuag chaw hauv pem teb thiab muab kev pom dav dua.
Kev teeb tsa raug tshem tawm: Yog tias koj lub tsev teev ntuj muaj qab nthab siab thiab xav tau kev txuag hauv pem teb. Pendant mounting tso cai rau lub vijtsam dai rau saum huab cua, muab lub kaum sab xis pom tau yooj yim dua.
Pem teb-mounted installation: Yog hais tias lub tsev teev ntuj tsis muaj phab ntsa lossis qab nthab txaus, qhov kev xaiv installation no muaj. Pem teb mounting yog yooj yim txav thiab reposition.
8. Suab kev koom ua ke
Kev sib xyaw suab yog ib qho tseem ceeb thaum xaiv thiab txhim kho lub tsev teev ntuj LED cov lus qhia rau pawg ntseeg. Cov teeb meem uas tuaj yeem ntsib suav nrog audio thiab video tawm ntawm sync, suab tsis zoo, kev sib txuas yooj yim, thiab cov cuab yeej siv tau. Txhawm rau kom ntseeg tau tias cov suab thiab cov yeeb yaj kiab tau synchronised, RTLEDs tau nrog cov txheej txheem video zoo. Kev xaiv lub suab zoo tuaj yeem txhim kho lub suab zoo, thiab peb lub tshuab tau tsim los ua haujlwm hauv ntau lub tsev teev ntuj. Tsis tas li ntawd, peb muab kev pabcuam tomqab muag kom paub meej tias cov xaim yog yooj yim, zoo nkauj thiab nyab xeeb. Txhawm rau kom tsis txhob muaj teeb meem kev sib raug zoo, nws raug nquahu kom xaiv tib hom lossis cov cuab yeej siv tau ntawv pov thawj.
RTLED tsis tsuas yog muab cov cuab yeej siv, tab sis kuj tseem muaj kev txhawb nqa thiab kev cob qhia cov kev pabcuam kom ntseeg tau tias kev ua haujlwm zoo ntawm lub cev. Nrog peb cov kev daws teeb meem, ntau yam teeb meem hauv kev sib koom ua ke audio tuaj yeem daws tau zoo kom ua tiav qhov zoo tshaj plaws audio thiab video kev paub. Yog tias koj muaj lus nug lossis xav tau kev qhia ntxiv, thovtiv tauj peb tam sim no.
