Lub Lumens Game
Thaum xaiv qhov kev yuav khoom ntawm ib qhov video projector, tej zaum qhov tseem ceeb tshaj plaws uas koj tau paub yog lumens tus naj npawb. Lumens yog ib qho kev ntsuas ntawm lub teeb pom kev zoo npaum li cas ib qhov video projector tau tawm. Qhov tseeb tiag, thaum ib lub chaw tsim khoom muab ib tus lej cim ntiag tug, koj yuav tsum ceev faj vim tias tsis muaj tus qauv uas yuav tsum tau siv - yog li hais tias Lumens ntaus nqi siv los ntawm ib hom ntawm cov ntawv tawm yuav tsis yog tib yam raws li lwm hom. Txawm li cas los xij, yog hais tias qhov lumens rating tau teev nyob rau hauv cov nqe lus ntawm ANSI lumens, uas yog ib qho kev lag luam uas zoo ib yam yog sib piv ob hom thiab ob qho tib si siv ANSI raws li lawv cov kev siv.
Dawb Lub Teeb Kom Muaj Tiag - Xim Brightness
Txawm li cas los xij, muaj ntau qhov xav txog los ntawm ntau npaum li cas lub teeb pom kev zoo ntawm ib qhov video projector. Thaum twg ib tus lumens ntsuam xyuas tau teev, qhov nws referencing yog ntau npaum li cas Dawb Teeb Tsog (WLO) los yog Dawb Brightness, tus projector muaj peev xwm ua tau, tsis tag nrho lub teeb tso zis thaum xim raug coj los xav. Piv txwv li, ob qhov projectors yuav muaj qhov ntsuas WLO tib yam, tiam sis xim lub teeb tawm (CLO), los sis Xim Brightness, yuav txawv.
Kev Sib Piv Ib Feem Ntawm-Ib Sab
Kom illustrate qhov sib txawv ntawm Dawb thiab xim xim, cov duab saum toj no qhia txog ib sab ntawm ib sab yeeb yaj kiab ntawm cov nyhuv xim ntawm cov duab video lumens, los yog lub teeb, tso tawm. Ob lub projectors nyob rau hauv cov duab muaj tib qho cov zis dawb Brightness, tiam sis txawv ntawm cov xim Color Brightness lawv muaj peev xwm tsim tau.
Yog vim li cas ho muaj qhov sib txawv hauv cov xim Color Illustration ntawm ob qhov projectors yog tias lub projector ntawm sab laug siv siv 1-Dip DLP qauv (Optoma GT750E), thaum lub projector ntawm txoj cai siv 3LCD tsim (Epson PowerLight Tsev Xinesmas 750HD). Ob qhov projectors muaj tib lub ntsiab lus teeb meem ( 720p ) thiab tib ANSI lumens WLO specification: 3,000. Qhov sib piv sib txawv ntawm qhov Optoma yog 3,000: 1 thiab rau Epson tau hais tias yog "txog" 5,000: 1.
Txawm li cas los xij, raws li koj pom, tus projector ntawm txoj cai zoo nkaus li muaj zog, xim ntau vibrant, as Well as tag nrho cov brightness, dua li cov projector ntawm sab laug.
Npaum Li Cas Lub Lag Luam Ntawm Tus Qauv Tsim Kev Xim Xim Ncauj
Yog vim li cas rau qhov sib txawv hauv cov dluab tso tawm, uas koj pom nyob hauv daim duab, yog hais txog qhov tsim ntawm ob qhov projectors. 3LCD tsim tso cai rau tag nrho cov xim dawb thiab xim kom dhau lub lens tas li, projecting thiab sib npaug ntawm White thiab xim Brightness. Txawm li cas los xij, nyob rau hauv 1-Chip DLP tsim , lub teeb tau taug kev los ntawm ib lub kauj vab thav xim uas muab faib rau cov xim liab, ntsuab, thiab xiav.
Hauv qhov 1-Chip DLP system, cov xim yog cov kwv yees raws li (hauv txhais tau tias, koj lub qhov muag tsis tau txais cov ntaub ntawv xim tsis tu ncua), uas tuaj yeem ua rau qis dua cov xim zis, raws li cov teeb zis dawb. Los ua kom tau qhov no, 1-Chip DLP projectors ntau zaus ntxiv ib qho xim tshiab rau cov xim xim xwv kom muaj zog Thaum Brightness, tab sis qhov tseeb tseem tias qhov xim ntawm Brightness tsawg dua cov Dawb Brightness.
Qhov sib txawv no feem ntau tsis tau teev los ntawm cov khw ua lawv cov duab kos. Dab tsi koj feem ntau pom yog ib qho leb tawm ntawm cov zis Lumens, tsis yog ib qho uas teev ob lumens specifications, ib qho rau WLO (Dawb Teeb Tawm) thiab ib qho rau CLO (Xim Teeb Tseg Zog), uas muab ib qho tseeb ntawm ntau npaum li cas xim Brightness tus projector yuav tsim.
Ntawm qhov tod tes, 3LCD Projectors ntiav ib lub iav / tho kev sib txoos (tsis muaj txav xim log) ua ke nrog ib tus ntiv tes sib cais rau txhua tus thawj xim (xim liab, kev ntshaw, xiav), kom ob leeg dawb thiab xim tas li ncav cuag koj lub qhov muag. Qhov no ua tau raws li Dawb thiab xim Brightness.
Raws li qhov tseeb ntawm cov cuab yeej siv los tsim cov duab los ntawm txhua lub projector siv nyob rau hauv daim duab saum toj no, rau 1-chip DLP projector ntawm sab laug los tsim kom ntau npaum li Brightness li lub 3LCD projector ntawm sab xis, nws xav tau ntau ntau dua Dawb Lub Teeb Khoom Muaj Zog tshaj li qhov project ntawm sab xis - qhov no txhais tau hais tias 1-chip DLP projector yuav tsum siv lub teeb ntim dua, thiab qhov nce ntawm kev siv zog.
Thaum kawg Siv - Vim Li Cas Lub Nrig Xim Qhov Ncauj Luag Tseem Ceeb
Raws li koj tuaj yeem pom los ntawm tus qauv duab nyob rau sab saum toj ntawm nplooj, Xim Brightness muaj ib qhov kev siv nyiaj ncaj qha rau koj saib ntawm qhov screen. Qhov no tuaj yeem yog qhov tseem ceeb tsis yog rau kev ua yeeb yam hauv tsev, tab sis kev saib hauv chav nyob qhov twg muaj qhov teeb meem ntawm lub teeb nyob rau hauv qhov hluav taws xob yuav pom tau yooj yim, kev pom 3D, qhov ci ntsa iab thaum saib los ntawm 3D iav yog qhov zoo tshaj plaws, thiab rau cov uas siv cov video projectors hauv kev kawm, kev ua lag luam, suav nrog kev mus ncig, qhov chaw uas lub projector yuav siv nyob rau hauv ntau lub chav nyob qhov twg lub teeb tswj tsis paub ua ntej txhais tes.
Kuj, ntxiv xim ci ntsa iab kuj ua rau kev xaav ntawm cov ntsiab lus nyob rau hauv daim duab, tsis hais txog kev daws teeb meem. Qhov tsuas yog qhov uas yuav muaj kev txom nyem thaum xim ci ntsa iab nce yog qhov sib npaug txhua qhov sib npaug. Txawm li cas los xij, muaj lwm txoj kev ua yeeb yaj kiab uas cuam tshuam txog qhov no.
