Thaum LED zaub screen siv hauv chav tswj, TV studio thiab lwm qhov chaw, nws yuav qee zaum ua rau moire cuam tshuam rau lub koob yees duab duab.Daim ntawv no qhia txog cov laj thawj thiab kev daws teeb meem ntawm moire, thiab tsom mus rau yuav ua li cas xaiv LED zaub screen kom txo lossis tshem tawm moire.
1. Lub moire tau los ua li cas?
2.Yuav ua li cas tshem tawm lossis txo moire?
3.Yuav ua li cas hloov daim phiaj qauv ntawm lub koob yees duab CCD thiab LED zaub?
4.Yuav ua li cas hloov tus nqi txheeb ze ntawm lub koob yees duab CCD thiab LED zaub daim phiaj qauv?
5.Puas muaj txoj hauv kev los tig qhov chaw tsis muaj luminous dub rau hauv qhov chaw luminous ntawm LED zaub?
Thaum noj cov duab ntawm lub vijtsam LED hluav taws xob hauv kev ua haujlwm, qee cov kab txaij txawv txawv thiab cov ripples tsis tu ncua yuav tshwm sim.Cov ripples no hu ua moire fringes lossis moire teebmeem.Moire nyhuv yog qhov pom kev pom.Thaum ib pab pawg ntawm kab lossis cov ntsiab lus tau pom nyob rau ntawm lwm pawg kab lossis cov ntsiab lus, cov kab lossis cov ntsiab lus sib txawv ntawm qhov sib txawv, lub kaum sab xis lossis qhov sib txawv.
Lub ntsiab cuam tshuam ntawm Moore nyhuv yog TV thiab lub koob yees duab.Yog hais tias lub teeb pom kev zoo ntawm cov pixels ntawm LED hluav taws xob zaub screen tsis sib npaug, cov duab zoo ntawm LED hluav taws xob zaub screen yuav raug cuam tshuam thiab glare yuav tshwm sim thaum lub vijtsam saib ze ze.Qhov no ua rau muaj kev sib tw zoo rau kev tsim cov TV studios thiab lwm yam khoom siv yees duab.
(1) Lub moire tau los ua li cas?
Moire:
Thaum ob tus qauv nrog spatial zaus sib tshooj, lwm tus qauv tshiab feem ntau yog tsim, uas feem ntau hu ua moire qauv (raws li qhia hauv daim duab 2).
Cov tsoos LED zaub screen yog teem los ntawm ywj siab luminous pixels, thiab muaj pom tseeb tsis luminous dub cheeb tsam ntawm lub pixels.Nyob rau tib lub sijhawm, lub ntsiab lus tseem ceeb ntawm lub koob yees duab digital kuj muaj qhov pom tseeb tsis muaj zog lub teeb pom kev thaum pom lub teeb.Thaum cov duab digital thiab yees duab digital muaj nyob rau tib lub sijhawm, tus qauv moire tau yug los.
Txij li thaum CCD (daim duab sensor) lub hom phiaj nto (photosensitive nto) ntawm lub koob yees duab zoo ib yam li daim duab nyob rau hauv nruab nrab ntawm daim duab 2, thaum lub tsoos LED zaub screen zoo ib yam li cov duab nyob rau sab laug ntawm daim duab 2. Nws yog tsim. ntawm lattice teeb emitting raj teem nyob rau hauv ib tug zoo ib yam.Tag nrho cov zaub screen muaj thaj tsam loj uas tsis muaj luminous, tsim ib daim phiaj zoo li cov qauv.Qhov sib tshooj ntawm ob daim ntawv moire zoo ib yam li sab xis ntawm daim duab 2.
(2) Yuav ua li cas tshem tawm lossis txo moire?
Txij li thaum LED cov duab kab sib cuam tshuam nrog lub koob yees duab CCD daim phiaj qauv los ua cov qauv moire, hloov cov nqi txheeb ze thiab kab sib chaws ntawm lub koob yees duab CCD kab sib chaws thiab cov qauv ntawm LED daim phiaj tuaj yeem tshem tawm lossis txo cov qauv moire.
(3) Yuav ua li cas hloov daim phiaj qauv ntawm lub koob yees duab CCD thiab LED zaub?
Nyob rau hauv cov txheej txheem ntawm kev kaw zaj duab xis, tsis muaj pixel nrog kev faib tawm tsis tu ncua, yog li tsis muaj qhov nrawm nrawm thiab tsis muaj moire.
Yog li ntawd, qhov tshwm sim moire yog ib qho teeb meem tshwm sim los ntawm digitalization ntawm lub koob yees duab TV.Txhawm rau tshem tawm cov moire, qhov kev daws teeb meem ntawm LED zaub screen duab thaij hauv lub lens yuav tsum nyob deb tsawg dua li qhov ntau zaus ntawm cov khoom rhiab heev.Thaum tus mob no tau ntsib, tsis muaj fringes zoo ib yam li cov sensor tuaj yeem tshwm sim hauv daim duab, thiab yog li tsis muaj moire yuav raug tsim.
Hauv qee lub koob yees duab digital, lub lim qis qis tau teeb tsa los lim qhov siab dua qhov dav ntawm daim duab txhawm rau txo qis moire, tab sis qhov no yuav txo cov duab sharpness.Qee lub koob yees duab digital siv ntau dua spatial zaus sensing ntsiab.
(4) Yuav ua li cas hloov tus nqi txheeb ze ntawm lub koob yees duab CCD thiab LED zaub daim phiaj qauv?
1. Hloov lub koob yees duab shooting lub kaum sab xis.Los ntawm tig lub koob yees duab thiab hloov me ntsis lub kaum sab xis ntawm lub koob yees duab, lub moire ripple tuaj yeem raug tshem tawm lossis txo.
2. Hloov lub koob yees duab shooting txoj hauj lwm.Los ntawm kev txav lub koob yees duab sab laug thiab sab xis lossis nce thiab nqis, koj tuaj yeem tshem tawm lossis txo cov mole ripple.
3. Hloov qhov chaw tsom rau ntawm lub koob yees duab.Kev tsom xam thiab kev nthuav dav siab uas pom meej dhau ntawm cov duab kos kom ntxaws yuav ua rau mole ripples.Kev hloov me ntsis ntawm qhov kev tsom xam tuaj yeem hloov qhov pom tseeb, yog li pab tshem tawm mole ripples.
4. Hloov qhov focal ntev ntawm lub lens.Cov lo ntsiab muag sib txawv lossis qhov ntev focal ntev tuaj yeem siv los tshem tawm lossis txo cov molar ripple.
LED zaub screen yog teem los ntawm ywj siab luminous pixels, thiab muaj pom tseeb tsis luminous dub cheeb tsam ntawm pixels.Nrhiav ib txoj hauv kev los tig qhov chaw tsis muaj luminous dub rau hauv thaj chaw luminous, thiab txo qhov ci ntsa iab nrog kev ywj pheej luminous pixels, uas tuaj yeem txo qis lossis txawm tias tshem tawm moire.
(5) Puas muaj txoj hauv kev los tig qhov chaw tsis muaj luminous dub rau hauv thaj chaw luminous ntawm LED zaub?
COB ntim txheej txheem LED zaub, nws yooj yim los ua qhov no.Yog tias peb muaj lub sijhawm los muab cov LED zaub ntawm COB ua ke nrog LED zaub ntawm SMD, peb tuaj yeem pom tau yooj yim tias: LED zaub ntawm COB emits lub teeb muag muag zoo li lub teeb ci ntsa iab, thaum LED zaub ntawm SMD pom tseeb tias qhov luminous hais yog ywj siab luminous ntsiab lus.Nws tuaj yeem pom los ntawm daim duab 3 tias txoj kev sib khi ntawm COB ntim yog qhov txawv ntawm SMD.Txoj kev sib khi ntawm COB ntim yog tag nrho lub teeb-emitting nto ntawm ntau lub teeb-emitting pixels ua ke.Txoj kev sib khi ntawm SMD ntim yog ib qho luminous pixel, uas yog ib qho kev ywj pheej luminous point.
MPLED tuaj yeem muab rau koj nrog LED zaub ntawm COB ntim txheej txheem, thiab peb cov khoom lag luam ST Pro tuaj yeem muab cov kev daws teeb meem zoo li no.LED zaub screen ua tiav los ntawm cob ntim txheej txheem muaj qhov sib nrug me me, pom meej dua thiab cov duab zoo dua.Lub teeb-emitting nti yog ntim ncaj qha rau ntawm lub rooj tsavxwm PCB, thiab cov cua sov tau ncaj qha mus rau ntawm lub rooj tsavxwm.Tus nqi thermal kuj yog me me, thiab cov cua kub dissipation muaj zog dua.Lub teeb saum npoo emits lub teeb.Zoo dua qub.
Xaus: Yuav ua li cas tshem tawm lossis txo cov moire ntawm LED zaub?
1. Kho lub koob yees duab shooting lub kaum sab xis, txoj hauj lwm, tsom teeb thiab lens focal ntev.
2. Siv lub koob yees duab zaj duab xis ib txwm siv, lub koob yees duab digital nrog lub ntsuas qhov ntsuas siab dua, lossis lub koob yees duab digital nrog lub lim dej qis.
3. LED zaub screen hauv COB ntim daim ntawv yog xaiv.
