Ua ntej ntawm tag nrho cov, nyob rau hauv cov nqe lus ntawm cov xim ntawm daim duab, lub mainstream LCD projectors yog tag nrho peb-chips, siv ywj siab LCD panels rau peb thawj xim ntawm liab, ntsuab, thiab xiav.Nyob rau hauv txoj kev no, qhov ci ntsa iab thiab qhov sib txawv ntawm txhua qhov xim channel tuaj yeem hloov kho nyias, qhov projection nyhuv yog qhov zoo heev, thiab cov xim zoo nkauj tuaj yeem tau txais.Hauv DLP projectors ntawm tib qib, tsuas yog ib daim ntawm DLP tuaj yeem siv tau, uas feem ntau txiav txim siab los ntawm lub cev lub zog ntawm lub log xim thiab xim kub ntawm lub teeb.Tsis muaj ib yam dab tsi los kho, tsuas yog cov xim muaj tseeb dua tuaj yeem tau.Txawm li cas los xij, piv nrog LCD projectors ntawm tib tus nqi, tseem muaj qhov tsis muaj cov xim ci ntawm cov npoo ntawm daim duab.
Qhov thib ob qhov zoo ntawm LCD yog nws lub teeb pom kev zoo.LCD projectors muaj ANSI lumen lub teeb tso zis ntau dua li DLP projectors nrog tib lub teeb pom kev zoo tib yam.Hauv kev sib tw high-brightness, LCD tseem muaj qhov zoo dua.Ntawm 7 kg hnyav projectors, cov uas tuaj yeem ua tiav qhov ci siab tshaj 3000 ANSI lumens yog LCD projectors.
Disadvantages ntawm LCD:
Qhov pom tseeb qhov tsis zoo ntawm LCD projectors yog qhov kev ua tau zoo ntawm qib dub yog qhov tsis zoo thiab qhov sib piv tsis siab heev.Cov xim dub tso tawm los ntawm LCD projector ib txwm zoo li grey, thiab cov duab ntxoov ntxoo tshwm sim dim thiab tsis muaj cov ntsiab lus.Qhov no tsis tsim nyog rau kev ua yeeb yaj kiab zoo li cov yeeb yaj kiab, thiab nws tsis txawv ntawm DLP projectors rau cov ntawv nyeem.
Qhov thib ob qhov tsis zoo yog tias cov qauv pixel tuaj yeem pom hauv daim duab tsim los ntawm LCD projector, thiab cov neeg tuaj saib zoo li tau saib daim duab los ntawm lub qhov rais pane.SVGA (800 × 600) hom LCD projectors tuaj yeem pom daim phiaj pixel kom meej txawm tias qhov loj ntawm lub vijtsam duab, tshwj tsis yog siv cov khoom siv ntau dua.
Tam sim no lub LCD tau pib siv lub micro lens array (MLA), uas tuaj yeem txhim kho kev sib kis tau zoo ntawm XGA hom LCD vaj huam sib luag, soften lub pixel kab sib chaws, ua rau lub pixel grid zoo thiab tsis pom tseeb, thiab yuav tsis muaj kev cuam tshuam rau cov duab kos. sharpness ntawm daim duab.Nws tuaj yeem ua rau LCD pixel qauv xav tias tuaj yeem txo qis kom zoo ib yam li DLP projector, tab sis tseem muaj qhov sib txawv me ntsis.
