Qhov kev xaiv ntawm pixel suab (P-tus nqi) rau sab hauv tsev LED cov ntxaij vab tshaus yuav tsum tau txiav txim siab raws li qhov pom qhov deb, pob nyiaj siv, thiab kev xav tau. Me me pixel suab tsis tas txhais tau tias ua tau zoo dua; qhov kev daws teeb meem zoo tshaj plaws yog qhov tsim nyog rau koj qhov xwm txheej tshwj xeeb. Nov yog qhov kev ntsuam xyuas ntxaws:
Me me pixel suab ua rau cov duab zoo dua, tab sis ntawm tus nqi siab dua.
Ultra-me me pixel suab (piv txwv li, P0.6, P0.9): Pitch me me pixel, ua rau cov duab nthuav dav mus txog qhov screen LCD, siab xim fidelity, thiab tsawg zog noj. Tsim nyog rau cov xwm txheej uas yuav tsum muaj cov duab zoo heev (xws li, siab- chav sib tham kawg, chaw hais kom ua, TV studios). Txawm li cas los xij, cov khoom lag luam no kim heev thiab muaj cov kev cai nruj rau kev teeb tsa ib puag ncig (xws li, flatness, cua sov dissipation).
Tsim nyog scenarios:
Kaw- saib ntau yam (piv txwv li, hauv 1-3 meters);
Lub sijhawm uas yuav tsum tau ua kom pom qhov siab - video txhais, cov kab kos kom ntxaws, lossis cov ntawv nyeem;
Cov neeg siv nrog cov peev nyiaj txaus uas nrhiav kev pom qhov kawg.
Saib nrug yog qhov tseem ceeb hauv kev xaiv pixel suab.
Kev sib raug zoo ntawm pixel suab thiab saib nrug:
Raws li kev paub hauv kev lag luam, qhov pom kev pom qhov deb (meters) ≈ pixel suab (millimeters) × 3000 ~ 5000. Piv txwv li:
P2.5 zaub: Qhov zoo tshaj plaws saib nyob deb li ntawm 7.5 ~ 12.5 meters;
P1.5 zaub: Qhov pom kev zoo tshaj plaws kwv yees li 4.5 ~ 7.5 meters. Yog tias qhov kev pom qhov deb tsawg dua li qhov pom zoo, qhov kev pom yuav raug cuam tshuam los ntawm pixelation; yog tias nws ntau dua li qhov pom zoo, nws yuav ua rau cov khoom siv khib nyiab (xws li xaiv P0.9 tab sis saib ntawm qhov deb ntawm ntau tshaj 5 meters).
Pom pom zoo sab hauv tsev pixel pitches:
P1.2 ~ P1.5: Tsim nyog rau qhov nruab nrab mus rau qhov ze ze saib (3 ~ 8 meters), xws li chav sib tham, chaw ua yeeb yam, thiab cov chaw saib xyuas;
P1.8 ~ P2.5: Haum rau qhov nruab nrab mus rau qhov ntev saib (5 ~ 15 meters), xws li khw malls, auditoriums, thiab chaw ntau pob;
P3 thiab saum toj no: Haum rau kev saib ntev ntev (ntau tshaj 10 meters), xws li cov theem loj hauv qab thiab cov chaw ua yeeb yam (tab sis tsawg dua cov ntawv thov sab hauv).
Sib npaug cov nyhuv thiab tus nqi, zam dhau kev nrhiav ntau ntawm me me pixel suab.
Tus nqi sib txawv: Rau txhua qhov kev txo qis hauv pixel suab (xws li, los ntawm P2.5 txog P2.0), tus nqi yuav nce 30% ~ 50%, thiab kev saib xyuas nyuaj kuj nce ntxiv. Piv txwv li:
P2.5 zaub screen raug nqi kwv yees li 60% ~ 70% ntawm P1.5 npo;
Lub vijtsam P0.9 tuaj yeem raug nqi 3 ~ 5 npaug ntau dua li lub vijtsam P2.5.
Tus nqi -kev xaiv muaj txiaj ntsig:
Yog tias qhov pom qhov deb ntev (piv txwv li, tshaj 10 meters), xaiv lub vijtsam P2.5 lossis P3 yuav txaus; tsis tas yuav mus nrhiav dab tsi hauv qab P1.5.
Yog tias cov peev nyiaj tsawg, qhov xav tau pixel suab tuaj yeem ua kom zoo, them nyiaj rau cov duab tsis txaus los ntawm kev txhim kho cov ntsiab lus tsim (xws li, siv cov ntawv loj, siab - cov ntaub ntawv sib piv).
Analogy rau sab nraum zoov LED cov ntxaij vab tshaus: Pixel pitch xav kom phim qhov kev siv scenario.
Sab nraum zoov piv txwv: Sab nraum zoov P10 cov lus qhia muaj qhov loj pixel suab (10mm), tab sis vim qhov pom qhov ntev (feem ntau tshaj 10 meters), lawv tseem nthuav tawm cov duab meej. Ib yam li ntawd, xaiv qhov screen sab hauv tsev yuav tsum yog raws li qhov tseeb scenario, tsis yog tsuas yog nrhiav ib qho pixel me me.
Cov lus pom zoo yuav khoom:
Qhia meej cov kev xav tau:
Txiav txim siab qhov kev siv tseem ceeb (piv txwv li, cov rooj sib tham, kev nthuav qhia, kev tshaj tawm) thiab saib qhov deb;
Ntsuas cov peev nyiaj ntau thiab cov kev xav tau ntawm cov duab zoo (xws li, seb puas xav tau 4K / 8K daws teeb meem).
Tham nrog cov kws tsim khoom lag luam: Muab cov tuam txhab nrog cov ntaub ntawv xws li kev siv cov xwm txheej, saib qhov deb, thiab peev nyiaj kom tau txais cov kev daws teeb meem; ua ntej cov tuam txhab lag luam uas muab rau ntawm - qhov chaw sim lossis cov ntaub ntawv tshawb fawb (xws li Shenzhen Dayuan Intelligent).
Sib piv cov nqi thiab ua qhov chaw mus ntsib: Sib piv cov lus hais, cov khoom tsis raug, thiab tom qab- kev muag khoom los ntawm ntau lub tuam txhab; ua ntawm - chaw mus ntsib cov tuam txhab lag luam los ntsuas lawv qhov ntsuas, cov txheej txheem tsim khoom, thiab ua tiav cov haujlwm kom txo qis kev pheej hmoo.
Cov ntsiab lus: Tsis muaj tus qauv ruaj khov rau "qhov zoo tshaj P-tus nqi" ntawm sab hauv LED cov ntxaij vab tshaus; nws yuav tsum tau txiav txim siab raws li qhov pom qhov deb, pob nyiaj siv, thiab qhov xav tau scenario. Ultra-me me pixel suab (piv txwv li, P0.9) muaj cov duab zoo tshaj plaws tab sis kim dua, haum rau ze -ntau, siab - qhov yuav tsum tau muaj; nruab nrab pixel suab (piv txwv li, P1.5 ~ P2.5) muab cov nqi zoo dua -kev ua tau zoo thiab npog feem ntau cov ntawv thov sab hauv. Nws raug nquahu kom xaiv raws li qhov xav tau tiag tiag thiab tsis txhob ua qhov muag tsis pom kev ua haujlwm.
