Nyob rau hauv lub ntiaj teb dynamic ntawm kev siv tshuab pom, LED cov ntxaij vab tshaus tau dhau los ua qhov chaw thoob plaws, txhim kho txoj hauv kev nthuav qhia thiab tsim kom muaj kev paub zoo. Ib qho kev txiav txim siab tseem ceeb hauv kev xa cov duab LED yog txiav txim siab qhov loj me rau ntau yam kev siv. Qhov loj ntawm LED zaub screen ua lub luag haujlwm tseem ceeb hauv kev ua kom muaj kev sib txuas lus zoo, kev pom, thiab kev cuam tshuam tag nrho. Nyob rau hauv tsab xov xwm no, peb delve rau hauv cov yam uas cuam tshuamLED zaubloj thiab muab kev nkag siab txog kev txiav txim siab paub.
Thawj thiab foremost kev txiav txim siab thaum txiav txim siab qhov loj ntawm ib qhoLED npoyog qhov pom kev deb. Kev sib raug zoo ntawm qhov screen loj thiab saib qhov deb yog qhov tseem ceeb hauv kev ua kom pom qhov pom kev zoo. Piv txwv li, nyob rau hauv cov chaw loj xws li chaw ntau pob lossis kev hais kwv txhiaj arenas uas cov neeg tuaj saib tau zaum deb ntawm qhov screen, cov zaub loj dua yog qhov tseem ceeb los xyuas kom meej pom cov ntsiab lus. Hloov pauv, hauv qhov chaw me me xws li cov khw muag khoom ib puag ncig lossis chav tswj hwm, qhov loj me me ntawm lub vijtsam yuav txaus.
Lwm qhov tseem ceeb yog qhov kev npaj siv ntawm LED zaub. Rau kev tshaj tawm thiab kev tshaj tawm lub hom phiaj, cov ntxaij vab tshaus loj dua feem ntau nyiam kom ntes cov neeg hla thiab xa cov lus zoo. Nyob rau hauv sib piv, rau cov ntaub ntawv qhia nyob rau hauv tshav dav hlau, tsheb ciav hlau chaw nres tsheb, los yog cov chaw lag luam, qhov sib npaug ntawm qhov loj thiab qhov sib thooj yog qhov tseem ceeb los pab kom yooj yim nyeem tau yam tsis muaj kev cuam tshuam rau tus neeg saib.
Qhov kev daws teeb meem ntawm LED zaub yog ib qho tseem ceeb uas cuam tshuam txog qhov loj me. Lub vijtsam loj dua nrog cov kev daws teeb meem siab dua kom ntseeg tau tias cov ntsiab lus zoo nkaus li ntse thiab muaj zog, txawm tias nyob ze saib qhov deb. Qhov no yog qhov tseem ceeb tshwj xeeb rau cov ntawv thov uas nthuav tawm cov duab lossis cov ntawv nyeem, xws li hauv cov chaw hais kom ua lossis chav sib tham. Kev tawm tsam qhov sib npaug ntawm qhov loj thiab qhov kev daws teeb meem yog qhov tseem ceeb kom muaj kev pom qhov pom tseeb.
Dab tsi yuav tsum yog Led Screen Loj?
Nws yog ib qho tseem ceeb heev kom paub qhov loj me ntawm qhov screen thaum xaiv qhov kev daws teeb meem.
Lub hom phiaj ntawm no yog txhawm rau tiv thaiv cov duab tsis zoo lossis cov kev daws teeb meem siab tsis tsim nyog (qee zaum nws yuav txawv nyob ntawm qhov project). Nws yog pixel suab uas txiav txim siab lub vijtsam daws teeb meem thiab muab qhov kev ncua deb ntawm LEDs hauv millimeters. Yog tias qhov kev ncua deb ntawm LEDs txo qis, qhov kev daws teeb meem nce, thaum yog tias qhov kev ncua deb nce, qhov kev daws teeb meem txo. Hauv lwm lo lus, txhawm rau kom tau txais cov duab du, lub vijtsam me me yuav tsum nyob ntawm qhov kev daws teeb meem siab dua (tsawg kawg ntawm 43,000 pixels yuav tsum tau tso saib cov yeeb yaj kiab txheem kom tsis txhob poob cov ntsiab lus), lossis rov ua dua, ntawm lub vijtsam loj. , qhov kev daws teeb meem yuav tsum raug txo kom 43,000 pixels. Nws yuav tsum tsis txhob hnov qab tias Led cov ntxaij vab tshaus tso saib video ntawm ib txwm zoo yuav tsum muaj tsawg kawg yog 43,000 lub cev pixels (tiag tiag), thiab ib tug high-resolution LED screen loj yuav tsum muaj tsawg kawg yog 60,000 lub cev pixels (tiag).
Loj Led Screen
Yog tias koj xav muab lub vijtsam loj hauv qhov pom luv luv (piv txwv li, 8 meters), peb xav kom koj siv lub vijtsam LED nrog virtual pixel. Tus lej pixel virtual yog suav los ntawm kev muab tus lej pixel ntawm lub cev los ntawm 4. Qhov no txhais tau tias yog lub vijtsam coj muaj 50,000 lub cev (tiag tiag) pixels, muaj 200,000 virtual pixels tag nrho. Nyob rau hauv txoj kev no, ntawm lub vijtsam nrog lub pixel virtual, qhov tsawg kawg nkaus ntawm kev pom yog txo mus rau ib nrab piv rau lub vijtsam nrog lub pixel tiag.
Saib Dista Yuav Ua Li Cas Qhov ze tshaj plaws saib qhov deb uas yog qhov kev ncua deb ntawm tus neeg saib ze tshaj plaws rau qhov screen yog xam los ntawm hypotenuse.
Kuv tuaj yeem xam qhov hypotenuse li cas? Lub hypotenuse yog xam los ntawm Pythagorean theorem raws li hauv qab no:
H² = L² + A²
H: Saib nrug
L: nrug ntawm pem teb mus rau qhov screen
H: Qhov siab ntawm qhov screen ntawm pem teb
Piv txwv li, qhov pom kev deb ntawm tus neeg 12m saum av thiab 5m deb ntawm qhov screen yog xam raws li:
H² = 5² + 12² ? Luas = 25 + 144 Luas = 169 H = 169 ? 13m ua
Ib puag ncig yam tseem ceeb yuav tsum tsis txhob raug saib xyuas thaum txiav txim siab qhov loj ntawm LED zaub. Hauv kev teeb tsa sab nraum zoov, xws li cov ntawv tshaj tawm digital lossis cov ntxaij vab tshaus hauv chaw ntau pob, qhov loj dua feem ntau tsim nyog los rub cov neeg tuaj saib ntau dua. Tsis tas li ntawd, cov khoom siv sab nraum zoov yuav tsum tau nruab kom tiv taus huab cua sib txawv, ntxiv rau qhov kev xaiv ntawm qhov loj thiab cov khoom siv.
Hauv kev xaus, qhov loj me me rau LED cov ntxaij vab tshaus yog qhov kev txiav txim siab ntau yam uas nyob ntawm cov yam xws li saib qhov deb, xav siv, kev daws teeb meem, nam piv, thiab kev xav txog ib puag ncig. Ua tib zoo saib xyuas ntawm cov xwm txheej no ua kom ntseeg tau tias qhov loj me uas tau xaiv ua raws li cov kev cai tshwj xeeb ntawm daim ntawv thov, xa cov kev paub pom zoo. Raws li thev naus laus zis txuas ntxiv mus, nrhiav qhov sib npaug ntawm qhov loj thiab kev ua haujlwm yuav yog qhov tseem ceeb hauv kev siv lub peev xwm tag nrho ntawmLED zaub screensthoob plaws ntau hom kev lag luam.
