Kev suav ntawm qhov pom kev ncua deb rau qhov hloov pauv ntawm LED qhia feem ntau yog nyob ntawm pixel pitch, qhov siab ntawm lub vijtsam, thiab kev daws teeb meem ntawm tib neeg lub qhov muag. Nov yog qee txoj hauv kev uas feem ntau siv xam:
I. Kev xam raws li Pixel Pitch
Yam tsawg kawg saib nrug:
Formula: Yam tsawg kawg saib qhov deb=Pixel Pitch (mm) × 1 (los yog 1000/1000, piv txwv li, hloov mus rau meters, tab sis feem ntau xam nyob rau hauv millimeters yog txaus).
Kev piav qhia: Qhov no yog qhov tsawg kawg saib qhov nrug ntawm qhov hloov pauv LED zaub tuaj yeem tso saib cov duab du yam tsis muaj qhov ua tau zoo.
Optimal Saib Distance:
Formula: Optimal Viewing Distance=(Pixel Pitch (mm) × 1000) to (Pixel Pitch (mm) × 3000) (unit: millimeters).
Los yog hloov mus rau meters: Optimal Viewing Distance=(Pixel Pitch (mm) × 1) rau (Pixel Pitch (mm) × 3) (unit: meters).
Kev piav qhia: Kev saib lub vijtsam hauv qhov kev ncua deb no muab cov duab meej meej thiab pom kev pom kev zoo. Qhov ntau yam no yog muab los ntawm kev sib xyaw ntawm tib neeg lub qhov muag lub peev xwm daws teeb meem thiab pixel ceev ntawm cov khoom siv hloov pauv hloov pauv LED.
II. Kev xam raws li qhov siab qhov screen
Maximum Saib Distance:
Formula: Qhov siab saib qhov siab tshaj plaws=Qhov siab (meters) × 30 (x).
Kev piav qhia: Qhov no yog qhov kwv yees qhov siab tshaj plaws saib nyob deb raws li qhov siab ntawm qhov screen. Nyob rau hauv qhov kev ncua deb, cov neeg saib tseem tuaj yeem pom meej meej cov ntsiab lus ntawm qhov hloov pauv LED zaub. Txawm li cas los xij, nws yuav tsum tau muab sau tseg tias qhov kev ncua deb no tsis yog qhov tseeb, vim tias qhov pom tseeb kuj cuam tshuam los ntawm ntau yam xws li ambient brightness, screen brightness, thiab qhov sib piv.
III. Muab xam raws li Human Eye Resolution
Lub peev xwm ntawm tib neeg lub qhov muag los daws cov duab cov ntsiab lus yog hu ua kev daws teeb meem, uas tuaj yeem ntsuas los ntawm lub kaum sab xis daws teeb meem, qhia los ntawm θ. Vim tias qhov tseeb θ me me, nws yog kwv yees li qhov sib npaug ntawm qhov kev ncua deb ntawm ob lub ntsiab lus daws teeb meem uas nyob ib sab thiab inversely proportional rau qhov pom L, piv txwv li, θ ≈ d / L (radians).
Ntawm qhov pom qhov deb, yog tias lub kaum sab xis saib ntawm ob lub pixels uas nyob ib sab tsawg dua qhov kev daws teeb meem, tib neeg lub qhov muag tsis tuaj yeem paub qhov txawv; yog tias nws loj dua qhov kev daws teeb meem lub kaum ntse ntse, yuav muaj qhov zoo li grainy, cuam tshuam rau qhov pom kev pom. Los ntawm kev suav, qhov zoo tshaj plaws saib qhov deb ntawm cov qauv rau kev hloov pauv LED tuaj yeem muab tau: L> (k × d) / θ, qhov twg d yog pixel suab (hauv metres), θ yog qhov pom qhov tsawg kawg nkaus uas tib neeg lub qhov muag tuaj yeem daws tau (tus nqi siv feem ntau yog 1 arc feeb, lossis 1/60 ntawm ib degree), thiab k yog qhov sib npaug 3 raws li 3, feem ntau yog 3. ntawm cov yam ntxwv pom ntawm tib neeg lub qhov muag).
Hauv cov ntsiab lus, peb tuaj yeem pom tau tias suav qhov kev ncua deb ntawm qhov hloov pauv LED zaub yog txheej txheem uas yuav siv rau ntau yam.
Kev suav cov txheej txheem rau saib qhov nrug ntawm Flexible LED zaub
