Tsis meej pem txog pixel suab, daws teeb meem, thiab saib qhov nrug? Phau ntawv qhia kev qhia no piav qhia txog yuav ua li cas teeb tsa koj lub teeb pom kev digital coj kom pom meej meej meej.
Nkag siab txog Pixel Pitch thiab kev daws teeb meem hauv Digital LED zaub
Rau cov neeg yuav khoom yav tom ntej thiab AV cov kws tshaj lij kev sib koom ua ke, kev taw qhia cov kev qhia tshwj xeeb ntawm kev lag luam tso tawm tuaj yeem dhau los. Kev xaiv tsis ncaj ncees txog kev daws teeb meem thiab qhov sib nrug ntawm diode tuaj yeem ua rau lub vijtsam pixelated uas nyuaj rau kev nyeem lossis, hloov pauv, dhau ntawm - engineering system uas tsis tas yuav ua rau koj cov peev nyiaj peev. Yuav kom ua tiav qhov pom tseeb, koj yuav tsum nkag siab txog kev sib raug zoo ntawm pixel suab thiab qhov kev daws teeb meem kawg ntawm kojcoj digital zaub.
Demystifying Pixel Pitch thiab Pixel Grid
Hauv nws qhov tseem ceeb, ibcoj digital zaubyog kev sib dhos ntawm ntau txhiab tus tib neeg lub teeb -emitting diodes pab pawg ua pixels. Lub sij hawm Pixel Pitch yog ib qho tseem ceeb tshaj plaws hauv kev txiav txim siab qhov muag pom ntawm koj cov zaub. Tus nqi me me txhais tau hais tias cov LEDs tau ntim los ze zog ua ke, tsim kom muaj pixel ceev dua thiab cov duab zoo dua nyob ze dua.
Thaum manufacturers tsimdigital LED zaub, lawv teeb tsa ib lub txee los tuav ib daim phiaj tshwj xeeb ntawm pixels. Piv txwv li, ib lub npov ib lub npov ntsuas 500mm los ntawm 500mm nrog lub pixel suab ntawm 2.5mm yuav muaj ib daim phiaj ntawm 200 los ntawm 200 pixels. Txhawm rau xam tag nrho cov kev daws teeb meem ntawm phab ntsa kho kom haum, koj yuav tsum ntxiv tag nrho cov kab rov tav thiab ntsug pixels thoob plaws tag nrho cov txee lub cev ua ke.
Xam saib qhov nrug thiab kev daws teeb meem xav tau
Kev nkag siab txog kev sib raug zoo ntawm pixel suab thiab saib qhov deb yog qhov tseem ceeb rau kev xaiv txoj caidigital zaub cojqauv. Yog hais tias lub pixel suab loj dhau lawm, cov neeg saib sawv ze ntawm qhov screen yuav pom cov duab ntawm lub teeb es tsis yog cov duab seamless, cov nyhuv hu ua pixelation. Piv txwv li, kev yuav ib qho zoo -pitch screen rau sab nraum zoov billboard saib ntawm 50 meters deb yog ib qho kev siv nyiaj tsis tsim nyog, vim tib neeg lub qhov muag tsis tuaj yeem paub qhov txawv ntawm qhov kev ncua deb.
Raws li kev lag luam tus qauv, qhov pom kev ntxhib los mos rau kev pom zoo tuaj yeem kwv yees siv 1-rau-1 metric: txhua 1mm ntawm pixel suab yuav tsum muaj kwv yees li 1 meter ntawm qhov pom qhov deb kom pom meej thiab meej. Rau qhov pom zoo sab hauv tsev uas cov neeg saib yuav zaum hauv 2 meters ntawm lub vijtsam, lub suab ntawm P1.8 lossis me dua yog qhov pom zoo.
Qhov cuam tshuam ntawm kev daws teeb meem ntawm cov ntsiab lus sib raug
Sib piv koj cov ntsiab lus pom rau cov neeg nyobcoj zaub digitalkev daws teeb meem yog qhov tseem ceeb rau kev tswj hwm kev nthuav qhia zoo. Tsis zoo li tus qauv siv TV, uas tau tsim los rau cov qauv ruaj khov xws li Full HD (1920x1080) lossis 4K (3840x2160), loj - nplai cov lus qhia tuaj yeem sib sau ua ke hauv kev cai, tsis yog - cov qauv duab thiab cov qauv sib piv.
Yog tias koj qhov kev daws teeb meem tag nrho tsis zoo li qhov sib piv ntawm koj qhov kev tawm tswv yim (feem ntau 16: 9 rau cov yeeb yaj kiab txheem), koj cov ntsiab lus yuav tshwm sim ncab, squished, los yog cropped ntawm ntug. Txhawm rau tiv thaiv qhov no, cov kws tshaj lij kev teeb tsa siv cov txheej txheem video los ntsuas cov teeb liab tawm tswv yim kom phim cov phiaj xwm pixel tiag ntawmdigital LED npo. Rau siab -kawg daim ntawv thov kev lag luam, cov neeg teeb tsa lub hom phiaj los teeb tsa qhov screen qhov ntev kom ntaus ib txwm muaj 16: 9 piv, tso cai rau cov txheej txheem nthuav tawm los ua si seamlessly yam tsis muaj cov khoom siv scaling.
Sib npaug Technical Specifications thiab Kev txwv nyiaj txiag
Thaum sau daim phiaj xwm kev yuav khoom rau ib qhocoj digital screen, koj yuav tsum sib npaug koj qhov xav tau pixel suab nrog qhov project peev nyiaj tiag. Vim hais tias zoo pixel suab cov ntxaij vab tshaus xav tau ntau dua LEDs ib square meter, tus nqi tsim khoom nce exponentially raws li pixel suab txo.
Piv txwv li, txav ntawm lub vijtsam P2.5 mus rau P1.2 npo ua rau cov pixel suav ib square meter ntau dua plaub zaug. Nrog rau cov nqi kho vajtse siab dua, ultra- cov ntxaij vab tshaus zoo yuav tsum muaj cov txheej txheem kev teeb tsa ntau dua, siab dua - lub peev xwm faib hluav taws xob, thiab cov cuab yeej kho tshwj xeeb. Yog li ntawd, cov neeg yuav khoom yuav tsum tsom mus rau kev xaiv lub suab uas phim qhov tseeb, tiag tiag -lub ntiaj teb saib tus cwj pwm ntawm lawv cov neeg tuaj saib es tsis yog xaiv qhov kev xaiv me tshaj plaws uas muaj.
Cov lus nug nquag nug (FAQs)
"P2.5" txhais li cas thaum saib cov duab digital?
Lub "P" sawv cev rau pixel suab, thiab tus naj npawb "2.5" sawv cev rau qhov kev ncua deb ntawm 2.5 millimeters ntawm qhov nruab nrab ntawm ib qho LED diode thiab qhov nruab nrab ntawm lub diode uas nyob ib sab ntawm lub rooj tsav xwm Circuit Court.
Vim li cas qhov zoo tshaj pixel pitch digital coj screen raug nqi ntau dua?
Raws li lub pixel suab txo qis, tus naj npawb ntawm ib tus neeg LED diodes xav tau los npog tib qhov chaw saum npoo av nce exponentially. Qhov no yuav tsum muaj cov ntaub ntawv raw ntau dua, ntev dua saum npoo- lub sijhawm tsim khoom, thiab kev ntsuas kev tswj xyuas nruj dua.
Kuv puas tuaj yeem tso cov qauv 4K cov ntsiab lus ntawm kev cai nam piv cov duab coj?
Yog lawm, koj tuaj yeem pub 4K qhov chaw rau lub kaw lus, tab sis koj yuav xav tau ib qho kev sib txuas ntawm LED video processor los teev, qoob loo, lossis tso lub 4K video qhov rais kom nws ua kom raug nrog lub cev qhov ntev ntawm koj cov zaub.
Grey Scale cuam tshuam li cas rau cov duab zoo ntawm lub teeb pom kev digital?
Grey Scale txiav txim siab qhov screen lub peev xwm los qhia cov xim gradients du thiab cov ntsiab lus hauv cov duab ntxoov ntxoo tsaus. High-cov tshuab ua tau zoo muaj 14-ntsis lossis 16-ntsis ua, uas tiv thaiv cov xim banding hauv qhov tsaus ntuj.
