Reflective cov ntxaij vab tshaus muaj lub hauv paus opaque, zoo cuam tshuam lub teeb flux poob rau lawv yuav luag sib npaug ntawm txhua qhov kev qhia hauv lub kaum sab xis ntawm 180 °. Daim duab ntawm lawv yog saib los ntawm sab projection apparatus. Cov ntxaij vab tshaus zoo li no tau teeb tsa hauv txhua lub xinesmas, tshwj tsis yog rau hnub xinesmas, nyob rau hauv uas cov yeeb yaj kiab tau tshwm sim ntawm lub teeb xa hluav taws xob. Qhov saum npoo ntawm cov ntxaij vab tshaus, raws li txoj cai, yog dawb-matte.

Lub teeb kis cov ntxaij vab tshaus yog ua los ntawm cov iav frosted, translucent yas los yog zaj duab xis-coated ntaub. Lawv kis lub teeb rays zoo, yuav luag tsis xav txog lawv. Daim duab ntawm lawv yog saib los ntawm sab opposite rau lub projection ntaus ntawv. Niaj hnub no lawv tau siv, ntxiv rau hnub xinesmas, hauv kev tshaj tawm thiab nthuav qhia kev teeb tsa.

Tshuaj ntsuam hom

Rau chaw nres tsheb installation, phab ntsa-mounted lossis qab nthab-mounted projection cov ntxaij vab tshaus yog siv. Yog koj yuav tsum txav lub vijtsam los ntawm chav mus rau chav, thiab coj nws nrog koj mus rau sab nraum zoov ua qauv qhia, koj yuav tsum tau yuav ib qho ntawm cov ntxaij vab tshaus mobile.

Screens rau nyob ruaj ruaj dov los yog ncab (ntawm ib tug ncej). Roll-up cov ntxaij vab tshaus tuaj yeem folded thiab nthuav tawm, cov ntxaij vab tshaus nro, raws li lub npe qhia, tau ncab ntawm ib qho tshwj xeeb thav duab (nrog rau cov khoom siv), thiab tas li coj lawv qhov chaw ntawm phab ntsa. Qhov kev xaiv no, raws li txoj cai, yog txiav txim siab los ntawm kev tsim thiab kev ua haujlwm ntawm chav tsev.

Nyob rau hauv tas li ntawd, yob -up projector cov ntxaij vab tshaus tuaj yeem yog lub caij nplooj ntoos hlav-loaded lossis motorized. Caij nplooj ntoos hlav-loaded yob cov ntxaij vab tshaus yog ntxuav tes thiab dov los ntawm lub caij nplooj ntoos hlav. Motorized cov ntxaij vab tshaus tau tsa thiab txo qis los ntawm ib qho lub cev muaj zog hluav taws xob . Motorized cov ntxaij vab tshaus feem ntau tuaj nrog wired keyboards, tab sis cov chaw taws teeb tswj yog muaj raws li kev xaiv.

Cov ntxaij vab tshaus txawb sib txawv ntawm hom kev tsim kho thiab kev teeb tsa. Muaj cov ntxaij vab tshaus desktop, nrog rau ntau hom kev tshuaj ntsuam hauv pem teb. Qhov nrov tshaj plaws ntawm cov nqi thiab kev ua haujlwm yog tripod npo . Lawv quav tau yooj yim thiab sai thiab yog lub teeb hauv qhov hnyav. Thawj cov ntxaij vab tshaus retractable los ntawm hauv pem teb vaj tse yuav txaus siab rau koj feem ntau rau lawv lub teeb yuag, yooj yim ntawm installation, raws li zoo raws li zoo heev tsim.

Ntsuam saum npoo

Niaj hnub nimno screen manufacturers muab ntau hom ntawm qhov chaw uas yog aimed ntawm kev daws ib qho teeb meem: mus rau lub siab tshaj plaws zoo duab rau tus saib. Lub vijtsam projection tuaj yeem ua tau ib lossis ntau yam haujlwm hauv qab no: ua kom qhov ci ntawm cov duab, ua kom nws qhov sib txawv, thiab tso cai rau lub teeb kom dhau mus yam tsis muaj kev cuam tshuam sab nraud. Txawm li cas los xij, koj yuav tsum xaiv qhov chaw zoo heev , txwv tsis pub ib feem ntawm cov neeg tuaj saib, thiab qee zaum txawm tias tag nrho cov neeg saib, tsuas yog yuav tsis pom daim duab.

Yuav pib nrog, cia peb nyob ntawm cov yam ntxwv tseem ceeb ntawm qhov chaw:
1. Tau txais - tus nqi txheeb ze uas qhia txog lub peev xwm ntawm qhov screen los cuam tshuam lub teeb poob rau nws. Qhov siab dua, qhov ci dua daim duab yuav pom los ntawm cov neeg saib.
2. Hloov siab tsis zoo - muaj peev xwm ua kom rov tsim dua qhov tsaus ntuj thiab lub teeb ntawm daim duab.
3. Lub kaum sab xis saib characterizes qhov chaw nyob rau hauv uas cov neeg saib tau yooj yim pom cov duab.

Ib qho kev daws teeb meem thoob ntiaj teb uas yuav ua kom pom cov duab zoo rau txhua tus neeg saib yog a matte dawb nto , tsim los ntawm cov tuam txhab ua Matte White (S, M, P), M1300, Panamax. Xws li ib tug nto muaj qhov loj tshaj plaws saib lub kaum ntse ntse thiab muaj tseeb xim luam tawm. Qhov nce ntawm no canvas yog 1, piv txwv li Nws tsis nce qhov ci ntawm daim duab, tab sis nws tsis txo nws ib yam.

Yuav txhim khu brightness , muaj ob hom nto: reflective (Datalux MFS, Pearlscent) thiab beaded nto (HighPower, iav Beaded). Qhov nce ntawm qhov chaw no txawv ntawm 2 mus rau 2.5. Thawj qhov chaw yog siv thaum lub projector mounted rau ntawm lub qab nthab , vim hais tias nws qhia nyob rau hauv cov kev taw qhia opposite rau qhov xwm txheej ntawm rays. Cov hlaws npog (iav nti npog) qhia txog lub teeb ci thiab tsuas yog siv tau yog tias lub projector raug teeb tsa ntawm lub tib theem li cov neeg tuaj saib, piv txwv li, ntawm ib lub rooj nyob rau hauv pem hauv ntej ntawm qhov screen. Nws kuj tseem yuav tsum tau coj mus rau hauv tus account tias qhov chaw muaj kev cuam tshuam loj heev muaj qhov txwv qhov pom, thiab cov neeg saib zaum deb ntawm qhov nruab nrab ntawm qhov screen yuav tsis pom daim duab. Cov chaw no yog siv nyob rau hauv cov chav nrog ci ambient lub teeb, nrog rau cov projectors uas tsis muaj teeb pom kev zoo.

Grey nto (High Contrast, HiDef Grey) yog siv rau txhim khu kev sib piv. Cov chaw no muaj qhov nce ntawm 0.8-0.9 thiab pom lub kaum sab xis loj. Lub peev xwm los ua cov xim dub sib sib zog nqus yam tsis muaj kev cuam tshuam lub teeb tones thiab cov xim dawb yog qhov zoo tagnrho rau kev ua txhua yam duab nraaj. Qhov saum npoo no nrov tshaj plaws nyob rau hauv lub creation ntawm lub tsev ua yeeb yam.

Vijtsam hom

Qhov no parameter yog qhov ratio ntawm qhov dav ntawm lub illustrated duab rau nws qhov siab. Ntau yam khoom siv rau kev saib yeeb yaj kiab hauv tsev tuaj nrog 9: 16 nam piv screen. Thaum rau lub chaw ua haujlwm version qhov zoo tshaj plaws screen hom yog 3: 4. Rau txhim kho qhov zoo ntawm cov duab yees duab, nws yog ib qho tsim nyog los xyuas kom meej tias qhov loj ntawm daim ntaub ntawv sib tw nrog cov qauv ntawm cov duab nws tus kheej kis los ntawm lub projector.

Yog tias koj xaiv hom tshuaj ntsuam tsis raug, koj tej zaum pom dub tuav nyob rau hauv qab los yog ob sab ntawm daim duab.

Cov ntxaij vab tshaus tau tshwm sim ntev ua ntej qhov tshwm sim ntawm cov yeeb yaj kiab projectors - txawm tias thaum kaj ntug ntawm lub hnub yug ntawm xinesmas. Thiab qhov no coj mus rau xws li ntau yam ntawm qhov sib piv ntawm lawv sab.

• Square hom 1: 1 . Ib hom ntawv ntau yam uas tso cai rau koj los tsim cov duab kab rov tav thiab ntsug. Diam duab slides tau projected rau cov ntxaij vab tshaus, mounted nyob rau hauv square thav duab.
• Yees duab hom 3:2 (1.5:1) . Raws li lub npe implies, lub vijtsam hom sib raug rau tus qauv duab ncej hom.
• Video format 4:3 (1.33:1) . Standard txhais TV ncej hom SD TV.
• Saib 16:9 (1.78:1) . Cov hom ntawv tshiab siab txhais TV HD TV.
• Widescreen 1.85: 1 nam piv . Ib hom ntawv rau cov yeeb yaj kiab.
• Cinematic nam piv 2.35: 1 . Qhov dav tshaj plaws nyob rau hauv xinesmas, wider tsuas yog nyob rau hauv panoramic xinesmas.

Hais txog video projection, nws ua rau kev txiav txim siab los tham txog tsuas yog peb hom - 1: 1, 4: 3 thiab 16: 9. Yog tias peb tsuas xav tau ib qho screen rau ua si tsis tu ncua video , SD or HD , ces nws tseem xaiv ntawm 4: 3 thiab 16: 9 hom.

Cov kws tshaj lij ntawm lub khw "Student" pom zoo 4: 3 hom raws li ntau ntau yam . Ntawm lub vijtsam 4: 3 nam piv, koj tuaj yeem tso saib 16: 9 nam piv duab los ntawm kev sau lub vijtsam dav. Thiab yog tias koj muaj lub vijtsam rollable, ces nws tuaj yeem nthuav dav raws nraim li ntau npaum li qhov tsim nyog mus ua si ib hom ntawv.

Chav chaw thiab qhov screen layout

Qhov screen yog optimally xaiv nyob rau hauv xws li ib txoj kev uas ib tug neeg nyob rau hauv lub chav tsev tau yooj yim parse cov ntawv thiab cov duab ntawm qhov screen. Txhawm rau xam qhov loj ntawm lub vijtsam canvas, nws raug nquahu kom coj los ntawm peb txoj cai yooj yim:

• Qhov siab ntawm qhov screen yuav tsum yog tsawg kawg yog 1/6 ntawm qhov deb mus rau kab kawg ntawm cov rooj zaum hauv chav
• Qhov deb los ntawm pem teb mus rau hauv qab ntug ntawm qhov screen yuav tsum muaj tsawg kawg yog 125 cm
• Thawj kab ntawm cov rooj zaum yuav tsum nyob ntawm tsawg kawg ob zaug qhov siab ntawm qhov screen
