Txawv "txoj cai ntawm qhov kev ua si" nyob rau hauv cov yeeb yam screen lag luam
Rau cov tsoos LED zaub loj-screen ua lag luam, qhov kev sib tw tseem ceeb yog "dot pitch".Ntawd yog, lub peev xwm los tsim cov khoom lag luam txhim khu kev qha nrog me me pixel pitches hauv txoj kev lag luam ntau dua yog "kab loj ntawm kev sib tw thev naus laus zis" hauvLED zaub loj screen kev lag luam.
Txawm li cas los xij, txij li cov yeeb yaj kiab yeeb yaj kiab ua lag luam tau raug tswj hwm los ntawm "projection" thev naus laus zis rau ib puas xyoo, lub hom phiaj ntawm kev sib tw hauv kev lag luam no tau poob rau "projector brightness".Cov ntsiab lus tseem ceeb ntawm qhov ci ntsa iab ntawm qhov projector ntawm qhov screen nyhuv yog "qhov loj npaum li cas ntawm lub vijtsam tuaj yeem ua tiav raws li kev txaus siab ntawm cov duab zoo": Yog li ntawd, cov yeeb yaj kiab yeeb yaj kiab muaj cov qauv ntawm cov khoom sib txawv xws li 7 meters, 10. meters, thiab 20 meters.
DCI daim ntawv pov thawj yog kev ua yeeb yaj kiab ua yeeb yaj kiab thiab kev tiv thaiv tus qauv coj los ntawm Hollywood cov ntsiab lus tog.Txawm hais tias nws txoj cai lij choj yog "kev yeem ua lag luam pab pawg txheej txheem", xyoo ntawm kev ua lag luam thoob ntiaj teb tau ua nws qhov kev lag luam nkag mus rau tus qauv rau "cov ntxaij vab tshaus thiab cov cuab yeej projection" hauv kev ua lag luam thoob ntiaj teb.
Yog li ntawd, yog hais tias tusloj LED npoxav nkag mus rau 20-meter yeeb yaj kiab ua lag luam, nws yuav tsum tau txais daim ntawv pov thawj DCI ntawm 20-meter screen.Tshwj xeeb tshaj yog tom qab ntau tshaj kaum 10-meter LED xinesmas cov ntxaij vab tshaus tau txais daim ntawv pov thawj DCI, daim ntawv pov thawj 20-meter no tsis yog teeb meem kev lag luam, tab sis qhov teeb meem "kev ua lag luam".Txij li thaum nws yog ib yam khoom ntawm cov cuab yeej tshiab ua raws li cov kev cai qub, qhov tseem ceeb tshaj plaws ntawm 20-meter LED screen DCI ntawv pov thawj tshiab yog tias nws tau coj kev hloov pauv loj hauv thaj tsam ntawm kev sib tw.
20 meters yuav tsum yog lub watershed ntawm "movie screen LED"
Lub 20-meter LED npo txhais li cas?Cov neeg soj ntsuam kev lag luam tau taw qhia tias tus nqi crossover ntawm LED cov ntxaij vab tshaus thiab DLP projection cov cuab yeej poob ib ncig ntawm 20 meters.Qhov ntawd yog hais tias, txawm hais tias ntau tshaj kaum 10-meter LED cov ntxaij vab tshaus tau txais daim ntawv pov thawj DCI, tag nrho cov ntawm lawv yog cov khoom uas nws tus nqi siab dua li cov khoom siv ua yeeb yaj kiab yeeb yaj kiab.
Tam sim no, LED cov ntxaij vab tshaus loj tau nkag mus rau hauv cov yeeb yaj kiab yeeb yaj kiab ua lag luam thawj zaug, thiab nws yog qhov tseeb tseem tsis tau lub sijhawm rau lawv tuaj yeem tsim cov cai thiab cov cai.Kev txuas ntxiv ua raws li cov khoom lag luam thawj cov cai ntawm kev lag luam yeeb yaj kiab yeeb yaj kiab tsis yog tsuas yog lav rau cov txiaj ntsig ntawm kev ua yeeb yaj kiab, tab sis kuj tseem muaj kev hwm rau tus cwj pwm ntawm "theatre chains" hauv kev ua lag luam tiag.Nyob rau hauv cov txheej txheem no, LED cov ntxaij vab tshaus zoo li yuav spliced nyob rau hauv qhov ntau thiab tsawg yuav tsum tau txais ib txwm tshuaj ntsuam specifications xws li "10m / 20m" kom tau txais daim ntawv pov thawj kev lag luam.
Nyob rau hauv lub plawv ntawm qhov projection projection khoom yog brightness theem.Lub 10-meter screen sib haum mus rau qhov nkag-theem brightness theem ntawm cov khoom siv projector nyob rau hauv kev ua lag luam ua yeeb yam, thiab yog ib qho ntawm cov khoom "khoom kim tshaj plaws".Lub vijtsam 20-meter txhais tau hais tias qhov ci ntawm qhov projector xav tau 4 npaug siab dua li ntawm 10-meter screen: txawm tias nws yog ib qho kev ci ntsa iab ntxiv lossis kev daws teeb meem dual-unit superimposition, kev nyuaj ntawm lub projector yuav raug tsa mus rau qib siab dua.
Nyob rau hauv kev sib piv, ntawm 20-meter screen 4K zaub ntawm ib qho screen LED zaj duab xis, cov txheej txheem tseem ceeb ntawm pixel pitch qhia yuav raug muab ob npaug rau piv nrog 10-meter 4K npo, thiab pixel ceev yuav raug txo los ntawm 75%.Txawm hais tias nws thaj chaw splicing kuj tau nce mus rau 4 npaug ntawm qhov screen 10-meter, qhov kev nyuaj ntawm qhov ntsuas qhov sib txawv ntawm qhov tseem ceeb tau txo qis, ua rau tus nqi hloov pauv ntau dua.Qhov no yuav pab kom maj mam tsim nws qhov kev sib piv kom zoo dua hauv kev sib tw nqi.
Nyob rau tib lub sijhawm, los ntawm kev xav ntawm cov neeg ua yeeb yaj kiab ua yeeb yaj kiab, 10-meter screen yog ib qho kev soj ntsuam kev lag luam.Lub vijtsam 20-meter tau tsom mus rau qhov pom kev poob siab, uas yuav ua rau muaj txiaj ntsig zoo ntawm qhov ci, qhov sib txawv, thiab xim ntawm lub vijtsam loj LED.Nyob rau tib lub sijhawm, 20-meter screen Hall, uas nrhiav kev cuam tshuam ntau dua, yuav raug nqi ntau dua rau kev ua yeeb yam.Ntxiv nrog rau qhov sib txawv ntawm cov kev xav tau rau qhov kev cuam tshuam, ntau yam khoom siv hauv qhov 10-meter Hall kuj tau txais kev teeb tsa "machine room-less" configuration.
Txawm li cas los xij, cov cuab yeej projection nyob rau hauv 20-meter nrog yuav tsum nyob hauv qhov chaw ntawm lub computer chav tsev - qhov no yuav pab tau qhov zoo ntawmLED npo lub ntuj tshuabchav-tsawg thov.Tsis tas li ntawd, kev ua haujlwm sib txawv ntawm 10-meter chav yuav tsis siab npaum li cov chav 20-meter: qhov chaw loj dua ntawm 20-meter chav tso cai rau nws tsim kom muaj kev sib tham, concerts, thiab e-kev ua si. Cov xwm txheej nyob rau hauv high-brightness hom ntawm LED loj screen, movie tsev noj mov, lub rooj sib tham nyob broadcast thiab lwm yam ntau yam kev khiav hauj lwm hom.
Qhov ntawd yog hais tias, DCI muab 10-meter LED zaj duab xis tshuaj ntsuam ntawv pov thawj, uas yog ntau dua ntawm cov cim kev pom zoo.Vim hais tias nyob rau hauv 10-meter nrog, qhov sib tw kom zoo dua ntawm LED cov ntxaij vab tshaus yog suppressed los ntawm cov cuab yeej projection.Txawm li cas los xij, tom qab DCI daim ntawv pov thawj ntawm 20-meter LED cov yeeb yaj kiab tso tawm, nws txhais tau hais tias qhov projection thiab LED cov ntxaij vab tshaus tau nkag mus rau qhov "kev ntxhov siab" kev sib tw ntau dua hauv kev lag luam yeeb yaj kiab, thiab txawm tias cov ntxaij vab tshaus LED muaj qhov zoo dua me ntsis.
Txhawm rau ua tiav, daim ntawv pov thawj DCI ntawm 20-meter screen ntawm LED zaj duab xis screen qhia tau hais tias qhov kev daws teeb meem tshiab no yog "ua kom loj hlob sai".Nws ntseeg hais tias nyob rau hauv lub neej yav tom ntej, yuav muaj ib tug ua tiav LED zaj duab xis screen daws teeb meem xws li los ntawm ib tug 7-meter me tsev mus rau ib tug IMAX loj screen.Ib puas xyoo keeb kwm ntawm xinesmas saw projection yog hais txog mus rau ib theem tshiab ntawm kev sib tw thiab kev koom tes ntawm ob technologies.
