Hais txog kev ncaj ncees, qhov ncaj ncees tshaj plaws hauv ntiaj teb yuav tsum yog lub sijhawm! Nws yeej tsis nyob rau ib feeb lossis ob, lossis maj nrawm. Hmoov zoo, peb tsis ua raws li nws maj, peb tab tom kawm, loj hlob, thiab siab tawv! Nws qhia tau hais tias kev loj hlob thiab kev loj hlob ntawm kev lag luam nyob rau hauv ob peb xyoos dhau los yog pom ntawm qhov muag liab qab. Tam sim no, muaj ntau hom khoom siv hauv khw, uas tau muab faib ua ob peb pawg: DLP rear-projection displays, LCD splicing cov ntxaij vab tshaus, thiab cov ntxaij vab tshaus LED. ntsib cov khoom no, koj puas tsis meej pem me ntsis? Nws tsis yog' tsis muaj teeb meem hnub no, Hualinuo coj koj los ua kev nkag siab yooj yim los ntawm DLP thiab lwm qhov kev xav.
Ua ntej, cia's qhia DLP rear projection. Raws li lub npe qhia, DLP rear projection yog ib hom ntawm rear projection projection technology. Nws yog optical mathematical reflection projection technology. Qhov tseeb, kev siv lub hauv paus ntsiab lus ntawm qhov projection rear yog qhov yooj yim heev, thiab ib feem ntawm cov cuab yeej tau teeb tsa sab hauv. Cov duab los ntawm lub projector yog magnified los ntawm lub lens thiab projection rau sab nraum qab ntawm lub screen, uas yog, rear projection. Qhov no yuav tsum tau tso lub optical projector nyob rau hauv ib lub npov ntawm ib qho kev ncua deb ntawm cov zaub screen, thiab lub screen tsuas yog lub luag hauj lwm rau lub screen bearing zaub muaj nuj nqi, yog li tsis muaj redundant cable ntawm cov zaub screen, thiab tag nrho cov nyob ntawm tej feem ntau yog tsom rau. lub embedded projector. qhov no. Yog li dab tsi yog qhov txawv ntawm DLP rear projection thiab LCD splicing?
Ib tug neeg nug yog tias DLP rear projection splicing yog patchwork. Kuv tuaj yeem qhia koj tias yuav tsum muaj lub luag haujlwm. Txhua yam stitched yuav tsum muaj seam, tab sis piv rau cov tsoos LCD npo (tsis yog seamless) LCD splicing npo, seam yog me me, tag nrho hauv 1 hli, thiab cov cuab yeej siv tam sim no tuaj yeem ncav cuag 0.5 hli. Ib qho laj thawj yog tias tsis muaj kab hluav taws xob ntawm qhov screen ntawm qhov hais txog DLP rear projection. Piv nrog LCD splicing cov ntxaij vab tshaus, qhov sib txawv ntawm lawv nyob rau hauv qhov sib txawv ntawm seams. Txhua tus muaj nws qhov zoo thiab qhov tsis zoo raws li hauv qab no:
DLP rear projection yog qhov ci, ci thiab siab sib txawv
Qhov tsis txaus ntseeg kuj tseem pom tseeb: ob qho tib si kev siv hluav taws xob thiab hluav taws xob hluav taws xob yog qhov loj, kev ua haujlwm tsis cuam tshuam ntev yuav ua rau kev laus ntawm lub projector, cov duab zoo yuav txo qis rau lub sijhawm, thiab qhov ntim kuj loj.
Qhov zoo ntawm LCD splicing screen: siab daws teeb meem, siab xim saturation, me me, lub neej ntev, tsis tshua muaj hluav taws xob
Disadvantages: Muaj cov seams pom tseeb
LED zaub yog lub teeb-emitting diodes, uas ncaj qha hloov hluav taws xob hluav taws xob mus rau lub teeb lub zog. LED yog pom los ntawm me me diode teeb hlaws dai, yog li nws cov granularity muaj zog dua li qhov rov qab qhov projection ntawm lub teeb ci. Qhov no yog qhov sib txawv tseem ceeb ntawm DLP rear projection thiab LED, tshwj tsis yog rau kev sib piv hauv qab no:
DLP rear projection pixel loj yog me me, siab txhais, haum rau saib ze.
Disadvantages: me me saib lub kaum sab xis, siab zog noj
Qhov zoo ntawm LED: lub teeb ci siab, tsis muaj seams, haum rau kev saib mus ntev
Qhov tsis zoo ntawm LED: pixels loj, tsis tshua muaj siab, thiab myopia tuaj yeem yooj yim ua rau qhov muag nkees.
