Active thiab passive 3D: twg 3d tsom-iav zoo dua?

Vim tias qhov tseeb pom tau tias tib neeg pom yog qhov teeb meem, peb tau sim ua kom ntev ib qho duab thaij duab ntawm lub ntiaj teb nyob rau hauv cov stereotypes thiab cov yeeb yaj duab zoo li qub. Zaj duab xis kev lag luam ntawm tus tig ntawm 20-21 centuries yog tsim nyob rau hauv xob laim ceev, muab peb tag nrho cov tshiab yees ntawm 3D TV. Nyob rau hauv 2011, qhov feem ntau sharply disputed ntawm tuam ntxhab txog twg 3 hom ntawv yog zoo dua.

Cov tuam txhab ua lag luam uas tsim cov 3D TVs tau xaiv los siv ib qho ntawm cov technologies kom tsim cov duab tso suab. Namely, LG thiab Vizio siv cov cuab yeej siv yees 3D, thiab Samsung, Panasonic thiab Sony tau xaiv lub nquag version. Txhua tus neeg pom qhov zoo ntawm lawv cov khoom, thiab peb nug peb tus kheej cov lus nug, uas 3d tshuab zoo dua thiab thaum, thaum kawg, koj yuav txaus siab rau 3D video tsis muaj tsom iav? Nws yuav tsum tau sau tseg tias lub tuam txhab Toshiba tseem tabtom sim txhawb lub tshuab tevnaus ntawm lub khw, uas tsis muaj qhov tsom iav. Nyob rau hauv lub meantime, thaum yuav ib tug 3D TV, koj yuav tsum txiav txim siab twg 3d iav yog zoo dua - passive, los yog ua ub.

Passive 3D

Cov khoom siv thev naus laus zis muaj cov khoom siv uas tsis tas yuav muaj hwj chim los thaum saib cov ntsiab lus 3D. Muaj ob lub ntsiab subspecies - anaglyphic thiab polarizing. Lawv lub ntsiab zoo dua yog cov nqi pheej yig. Qhov pheej yig anaglyphs yog ua los ntawm duab los qhia thiab iav ntawm ob xim. Tsim ib lub hom ntim nyhuv, lawv ua cov duab dull thiab faded, poob qee cov ntaub ntawv xim.

Polarization 3D iav kuj muaj ob lub subspecies: linearly polarized thiab nrog polarization yeej. Pom ib daim duab kom ruaj khov muaj zog, siv cov tsom iav nrog txoj kab sib dhos, koj yuav tsum tau ua kom lub taub hau nyob rau ntawm txoj hauj lwm ntsug. Yog vim li cas yog tias thaum displaying cov ntsiab lus, ib lub qhov muag observes duab vertically polarized, thiab lwm tus yog horizontally polarized. Qhov teeb meem no yog kho nyob rau hauv txoj kev sib tho polarization, tab sis nws yuav tsum siv lub lim thiab lub tshuab, nws tsis pom zoo tias cov 3D glasses yuav dhau mus.

Qhov zoo ntawm kev siv tshuab ua ntej ua ntej lub koom haum tseem yog tias tus neeg pom pom ib txhij ob cov dluab thiab tus ncej tus nqi tsis yog khuam tib lub sijhawm.

Nquag (nrog shutter) 3D iav

Thaum nug 3d tsom-iav zoo dua, cov neeg lag luam ntawm cov qauv ua haujlwm yuav tau confidently hu lawv cov khoom. Thiab qee qhov twg, lawv yuav ua pov thawj ua qhov yog. Cov duab zoo li cov tsom iav yog qhov yooj yim dua (xim ci ntsa iab tsis ploj) thiab cov neeg tau txais kev pab ntau hom tsom iav.

Rau cov tsom iav qhov muag, koj xav tau lub zog ntawm lub zog uas pub lub qhov rooj nkag rau hauv lub ntsiab muag. Hauv qhov no, tus ntaus ntawv rau kev ua haujlwm, ua haujlwm nrog kev siv cov duab ci sab nrauv, ua rau hauv TV. Cov xim ua kua dej ua kua, qhib thiab kaw nyob rau hauv lem, qhia txhua qhov muag ib qho duab ntxiv. Tsom iav los ntawm cov roj teeb me me.

Cov tsom iav xws li cov khoom kim heev tshaj qhov qub tsis zoo, vim yog cov nqi siab ntawm kev tsim khoom. Nqi kev ntsuas pib ntawm 50 mus rau 100 dollars. Nyob rau hauv cov qauv ntawm 3D TVs muaj tsuas yog ib nkawm ntawm cov tsom iav stereoscopic, yog li rau kev saib nws yog tsim nyog yuav ntau dua ob peb. Qhov tsis zoo ntawm cov qauv ua ub ua no yuav tsis sib txig sib luag thiab pom kev tsis txaus siab. Qhov zoo ntawm daim duab nyob ntawm tus ncej tus nqi - qhov siab dua nws yog, qhov zoo dua qhov kev tshwm sim.

Hnub, lo lus nug ntawm 3d tsom-iav yog qhov zoo nyob qhib. Passive technologies yog txaus siab nrog tus nqi tsawg, tab sis disappoint tsis dhau siab zoo. Hauv kev ua ub no rau cov duab uas koj xav tau ib rooj ntxuam siab Full HD 1080p, uas nyuam qhuav tau siv cov ntshav tsom iav xwb. Lwm drawback ntawm active tsom iav, ntxiv rau lawv cov nqi siab, yog qhov muag ceev ceev thiab mob taub hau. Tab sis npog, yog tias peb sib cam uas 3d tsom-iav zoo dua, 3D-TV tshuab tsis pom iav yog tsim tau sai, thiab tsis ntev no, hnub tim, qhov teeb meem no yuav ploj los ntawm nws tus kheej.
