3D Active vs 3D Passive
Yog tias koj tau mus rau Cinema los saib 3D yeeb yaj kiab lossis mus rau pub rau saib qee qhov kev sib tw 3D kis las, ces koj yuav tau ntsib ib qho ntawm cov thev naus laus zis no, txawm tias nws nyiam dua tias koj tau ntsib 3D passive. tshuab. 3D thev naus laus zis tau siv los ua cov khoom lag luam siab kawg rau cov neeg tuaj saib tsawg tsawg ob peb xyoos dhau los, tab sis nrog kev txhim kho los ntawm kev siv thev naus laus zis, peb muaj hmoo kom muaj 3D TVs hauv peb lub tsev rau tus nqi qis dua. Peb lub hom phiaj yog los sib piv thiab sib piv lub ntsiab ob lub thev naus laus zis siv hauv 3D panels. Peb yuav tham txog lawv tus kheej ua ntej thiab tom qab ntawd muab kev sib piv ntawm lawv.
Passive 3D yog dab tsi?
Qhov no tau ua lag luam loj uas tau siv yuav luag txhua qhov chaw. Cov xinesmas thiab pubs twv yuav raug hu siv Passive 3D thev naus laus zis vim tias nws yooj yim dua thiab cov iav koj yuav tsum hnav yog pheej yig. Kuv yuav piav qhia seb qhov kev xav ntawm 3D yog tsim los ntawm Passive 3D cov lus siv hauv xinesmas ua ntej.
Nyob hauv xinesmas, ob daim duab uas muaj polarized nyob rau hauv cov lus qhia sib txawv tau npaj rau qhov screen. Ua li ntawd, koj xav tau ib qho tshwj xeeb 3D projector thiab feem ntau ntawm lub sijhawm; Cov 3D projectors tshwj xeeb no muaj ob lub projectors. Txhawm rau saib cov duab no (xws li yeeb yaj kiab yog qhov ua tiav ntawm cov duab; yog li, thaum kuv xa mus rau ib daim duab, koj tuaj yeem xav tias nws yog ib ntu ntawm cov duab; piv txwv li, yeeb yaj kiab, thiab), koj yuav tsum hnav lub iav polarized. Cov tsom iav no muaj lo ntsiab muag uas polarize cov duab rov qab mus rau qhov qub. Qhov ntawd txhais tau hais tias lawv polarize cov duab nyob rau hauv qhov kev taw qhia rov qab piv rau cov duab projected. Qhov tshwj xeeb ntawm cov iav yog tias lawv tsuas ua rau koj pom cov duab sib xws. Koj lub qhov muag sab xis tsuas pom cov duab sab xis xwb vim tias lub lens sab xis yuav thaiv cov duab sab laug, thiab koj lub qhov muag sab laug tsuas pom cov duab sab laug xwb vim tias sab laug lens yuav thaiv cov duab sab xis. Muaj ob txoj kev polarization uas tau siv, ib yam nkaus. IMAX 3D siv linear polarization, thaum ncig polarization yog siv hauv RealD. Qhov sib txawv ntawm lawv yog ib lub ntsiab lus sib txawv ntawm nws tus kheej, tab sis hauv luv luv, koj yuav tsum ua kom koj lub taub hau uptight hauv linear polarization txheej txheem thaum, nyob rau hauv cov txheej txheem polarization ncig, koj tuaj yeem qaij koj lub taub hau me ntsis ua ntej poob qhov tuav koj muaj ntawm 3D duab..
Hauv TV, dab tsi tshwm sim yog tias TV muab ib nrab ntawm pixel rau cov duab sab xis thiab ib nrab rau sab laug duab. Kev txiav txim siab tshwm sim ib yam li kuv tau piav qhia ua ntej. Qhov no yuav ua rau koj ntsib teeb meem daws teeb meem, tab sis qhov ntawd tau hais, thiab. Lub Active 3D thev naus laus zis tau siv los ua qhov zoo tshaj plaws rau kev daws teeb meem freaks, tab sis tam sim no, qhov zoo tshaj plaws 3D TV kev paub yog muab los ntawm LG Passive 3D TV, yog li peb tuaj yeem hais tias Passive 3D thev naus laus zis tau nrawm.
Dab tsi yog Active 3D?
Ntawm qhov sib piv rau Passive 3D, Active 3D yog qhov ua tau zoo ntawm kev sau ntawv. Cov cuab yeej siv hauv Active 3D yog qhov nyuaj thiab txawv ntawm Passive 3D. Nws tau siv los ua qhov zoo tshaj plaws 3D kev paub txog kev daws teeb meem thiab nws tseem nyob hauv feem ntau ntawm cov xwm txheej, tab sis tsis ntev los no LG tau tshwm sim nrog Passive 3D uas tuaj yeem tso saib HD 1080p video tiag tiag uas yog khoom kim heev tsuas yog muaj nrog Active 3D ua ntej. Kuv yuav piav qhia seb Active 3D ua haujlwm li cas hauv cov ntsiab lus ntawm TV.
Qhov no kuj muaj lub tswv yim ntawm daim duab sab laug thiab sab xis. Hloov chaw ntawm kev faib cov pixels ua ob, lub vaj huam sib luag tso saib tshiab ntawm tus nqi tseem ceeb uas pom cov duab sab laug thiab sab xis hloov. Tus nqi refresh yog feem ntau ntau dua 100Hz, yog li koj yuav tsis pom qhov hloov pauv. Cov hauj lwm tas li yog nyob ntawm iav koj hnav. Koj yuav tsum hnav ib hom iav tshwj xeeb hu ua Active Shutter iav. Raws li lub npe qhia, nws ua raws li lub kaw lus. Lub lens sab xis kaw thaum lub vijtsam pom cov duab sab laug thiab lub lens sab laug kaw thaum lub vijtsam pom cov duab sab xis. Tej zaum koj yuav xav tias lub khob no yuav tsum zoo li loj nrog cov kaw, tab sis nws ua tiav txoj haujlwm no siv cov kua siv lead ua kua. Cov lo ntsiab muag no tuaj yeem hloov pauv ntawm pob tshab thiab opaque hauv ib feem ntawm ob thiab koj yuav tsis hnov dab tsi. Lub xeev opaque yog synonymous rau kaw lub xeev, thiab lub xeev pob tshab yog synonymous rau qhib shutter xeev. Tej zaum koj yuav xav tsis thoob li cas lub TV syncs cov duab nrog lub iav koj hnav. Zoo, feem ntau cov Active 3D TVs muaj IR emitter uas qhia tias cov duab twg tau tshwm sim tam sim no, thiab iav nyeem qhov no thiab ua raws li. Nws yog ib qho tsim nyog los hais tias qhov kev hloov tshiab ntawm cov iav tuaj yeem ua tau tus nqi siab dua li TVs, thiab qhov txwv tsis pub tshaj yog qhov tseeb ntawm cov khoom vaj huam sib luag.
Yog hais tias txhua lub suab nrov, qhov ntes yog dab tsi? Zoo lub TV tsis yog kim, tab sis Active 3D Shutter tsom iav yog kim heev. Feem ntau, tshaj $150 uas txhais tau tias nws yuav raug nqi dearly yog tias koj yuav muaj ob peb khub.

Kev Sib piv luv luv ntawm Passive 3D vs Active 3D? • Passive 3D siv ob daim duab polarized nyob rau hauv cov lus qhia sib txawv thiab rov qab polarized iav los muab qhov kev nkag siab ntawm qhov tob, thaum Active 3D siv cov txheej txheem ntawm cov duab uas hloov pauv ntawm lub siab refresh npaum li cas nrog lub Shutter iav los muab kev nkag siab. ntawm qhov tob. • Passive 3D TVs raug nqi ntau dua Active 3D TVs. • Cov iav rau Passive 3D TVs kuj pheej yig piv rau cov iav siv hauv Active 3D TVs, uas kim heev. |
Zaj lus
Qhov xaus, qhov no, yuav yog tus neeg siv tsis ncaj ncees. Tab sis cia kuv piav qhia qee cov ntsiab lus uas tsim nyog nco txog ntawm ob lub thev naus laus zis no. Raws li peb tau hais, Active 3D tau zoo dua ua ntej, tab sis Passive 3D tab tom ntes tam sim no. Yog li ntawd, hais txog kev daws teeb meem, Active 3D thiab Passive 3D tau txais qhov sib npaug. Tab sis qhov tseeb ntes yog nrog cov tsom iav. Cov iav 3D Passive yog pheej yig tus nqi ob peb bucks, thaum Shutter tsom iav yog kim heev thiab ua rau nws muaj nqis peev yog tias koj yuav yuav 3D iav rau tag nrho tsev neeg. Tsis tas li ntawd, Shutter 3D tsom iav yog qhov loj thiab hnyav. Qhov tseeb tias lawv muaj roj teeb thiab cov roj teeb yuav tsum tau them ua rau lawv npau suav phem yog tias koj muaj ntau lub iav. Hauv Active 3D thev naus laus zis, feem ntau ntawm cov teeb meem yog tsim los ntawm cov roj teeb qis hauv lub khob. Lwm qhov uas yuav tsum tau muab sau tseg yog tias Active 3D thev naus laus zis tuaj yeem ua rau koj mob taub hau vim qhov tsis sib xws tshwm sim hauv cov duab vaj huam sib luag, nrog rau, iav koj hnav. Qhov no yuav txawv ntawm ib tus neeg mus rau lwm tus, thiab hom TV uas koj siv, yog li nws ntau dua ntawm tus kheej saj, tab sis yuav tsum ceeb toom, qhov ntawd yuav tshwm sim. Tsis tas li ntawd, tej zaum koj yuav xav xav txog tus nqi hloov ntawm lub khob, yog tias lawv tawg los ntawm kev sib tsoo, tshwj xeeb tshaj yog tias koj muaj menyuam yaus.
Ntawm qhov tod tes, tsis muaj qhov teeb meem no yog teeb meem hauv Passive 3D thev naus laus zis. Tsis muaj flickering muaj, yog li koj tuaj yeem txaus siab rau Passive 3D kev paub rau lub sijhawm txuas ntxiv. Passive 3D tsom iav yog lub teeb thiab pheej yig thiab tuaj yeem hloov tau yooj yim. Qhov teeb meem nkaus xwb nrog Passive 3D thev naus laus zis yog tias lawv tuaj yeem ua qhov kev daws teeb meem qis dua li Active 3D cov lus tam sim no. Qee tus hais tias qhov tob thiab qhov ci ntawm daim duab kuj txawv, tab sis hauv kuv tus kheej kev paub thiab rau cov lus qhia ntawm cov neeg muag khoom nrov, qhov no tsis yog li ntawd. Yog li ntawd yog txhua yam peb tuaj yeem hais tam sim no thiab cia siab tias, Passive 3D TVs nrog cov kev daws teeb meem HD tiag tiag yuav muaj los ntawm ntau tus neeg muag khoom ntawm tus nqi qis.
