Cov kev lag luam ua yeeb yaj kiab thiab tshaj tawm tau siv ntau xyoo los nrhiav txoj hauv kev los coj cov kev lag luam digital mus rau lub neej ntawm qhov teeb meem. Ntsuab -screen compositing ntev dominated qhov kev rau siab, tsis tau nws cov kev txwv - los ntawm inconsistent teeb pom kev zoo mus rau ntev post- ntau lawm voj voog - khaws cov tswv yim pab pawg tethered rau workflows uas tawm tsam kom phim qhov ceev ntawm niaj hnub zaj dab neeg. Kev tsim khoom siv virtual, tsim nyob ib puag ncig tiag tiag - lub sijhawm ua cov cav thiab loj - hom LED ntim, tau hloov pauv qhov sib npaug.
Niaj hnub no, ntau lawm studios nyob rau hauv yuav luag txhua lub teb chaws ua hauj lwm ib co qauv ntawm LED theem. Cov thev naus laus zis tso cai rau cov thawj coj thiab cov kws ua yeeb yaj kiab taug kev mus rau ib puag ncig los ntawm cov duab tiag tiag digital scenery uas teb lub sijhawm tiag tiag rau lub koob yees duab txav, teeb pom kev zoo, thiab txawm tias huab cua cuam tshuam hauv software. Qhov tshwm sim yog qhov kev paub txog kev tua uas ua rau lub ciam teb ntawm lub cev thiab lub ntiaj teb digital - kev hloov pauv uas cuam tshuam qhov cuam tshuam loj rau cov khoom siv kho vajtse ntawm qhov nruab nrab ntawm nws tag nrho.
Dab tsi tshwm sim hauv XR theem
Qhov kev muaj tiag txuas ntxiv (XR) theem feem ntau muaj cov phab ntsa LED nkhaus, lub qab nthab vaj huam sib luag, thiab qee zaum ntxiv sab vaj huam sib luag tau teem rau raus lub koob yees duab hauv 270-degree lossis puv-360-degree ib puag ncig. Lub cav rendering pub tas mus li, tsis tshua muaj latency video rau ntawm phab ntsa, thaum lub koob yees duab captures lub scene raws li lub keeb kwm yav dhau yog tiag tiag.
Rau qhov system no ua haujlwm kom raug, LED zaub yuav tsum ua kom tau raws li cov txheej txheem nruj dua li cov qauv kev lag luam lossis cov qauv digital billboard. Refresh tus nqi, qhov tseeb xim, qhov tob grey, thiab lub kaum sab xis saib tag nrho dhau los ua qhov hloov pauv tseem ceeb - tsis yog qhov kev nyiam pom xwb. Ib lub vaj huam sib luag uas ua tau zoo txaus hauv chav sib tham tuaj yeem qhia pom cov qauv moiré, xim banding, lossis cov lus tsa suab tsis meej thaum lub koob yees duab xinesmas pib tua nws.
Lub luag haujlwm ntawm Refresh Rate thiab Greyscale qhov tob
High refresh npaum li cas sawv tawm raws li tej zaum qhov feem ntau tham specification nyob rau hauv virtual ntau lawm voj voog. Thaum lub koob yees duab nrog lub tshuab kaw lus - lossis lub kaw lus hluav taws xob khiav ntawm lub sijhawm tshwj xeeb - scans lub vaj huam sib luag LED ua haujlwm ntawm tus nqi qis dua, cov duab sensor ntes cov kab scan ib nrab es tsis yog ib qho ua tiav. Qhov tshwm sim tshwm rau ntawm qhov screen raws li ib tug flickering band los yog dov distortion uas renders txwv tsis pub siv footage unusable.
Cov vaj huam sib luag tsim los rau XR ib puag ncig feem ntau ua haujlwm ntawm tus nqi tshiab ntawm 3,840 Hz lossis siab dua, uas ua kom ntseeg tau tias txawm tias siab -thav duab- tus nqi xinesmas koob yees duab ntes cov duab tiav, ruaj khov. Ntxiv nrog rau qhov refresh npaum li cas, greyscale qhov tob plays lub luag haujlwm tseem ceeb sib npaug. Tsaus greyscale - feem ntau nyob rau hauv qis dua - cov khoom lag luam LED nqi - ua rau thaj chaw duab ntxoov ntxoo thiab hloov maj mam tonal gradations rau posterize, stripping tawm ntawm qhov tob atmospheric uas cov thawj coj thiab cov thawj coj ntawm kev yees duab ua haujlwm hnyav kom ua tiav.
Tsis tas li ntawd, xim ntim qhov sib xws nyob thoob plaws lub vaj huam sib luag saum npoo tseem ceeb heev hauv cov ntsiab lus no. Txawm tias me me brightness variations ntawm cov nyob ib sab modules tuaj yeem tsim cov seams pom thaum lub koob yees duab ntes phab ntsa ntawm lub kaum sab xis dav. Tight uniformity kam rau ua, ua ke nrog kev ua haujlwm kom zoo, cais cov vaj huam sib luag haum rau cov khoom siv virtual los ntawm cov uas tsuas yog nqa tus lej pixel qis.
Me Pixel Pitch: Ib qho tseem ceeb pib taw tes, tsis muaj kev lav
Fine pixel suab tau dhau los ua ib qho zoo sib xws nrog siab -zoo sab hauv LED zaub - thiab yog vim li cas. Raws li lub pixel suab txo qis, qhov tsawg kawg saib qhov nrug luv luv, uas txhais tau hais tias lub koob yees duab tso ob peb meters ntawm phab ntsa LED tseem tuaj yeem ua rau tus kheej pixels hauv qab qhov kev daws teeb meem ntawm lub lens. Feem ntau XR cov qauv tsim qauv qhia pixel pitches xws li P1.2 txog P2.5 nyob ntawm seb lub studio loj, pob nyiaj siv, thiab qhov sib thooj ntawm lub koob yees duab yuav ua haujlwm.
Uas tau hais tias, pixel suab ib leeg tsis lav qhov kev tsim tawm -cov txiaj ntsig tau npaj. Ob lub vaj huam sib luag nqa qhov zoo ib yam P1.9 specification tuaj yeem xa qhov sib txawv ntawm - lub koob yees duab kev ua tau zoo nyob ntawm LED nti zoo, tsav IC, kho qhov muag diffusion, thiab kev tswj xyuas thermal tsim. Yog li ntawd, cov neeg tsim khoom tsim khoom uas ntsuas cov khoom siv LED rau cov theem virtual feem ntau tsim cov koob yees duab kuaj rau hauv cov txheej txheem kev yuav khoom es tsis yog cia siab rau cov ntawv qhia tshwj xeeb ib leeg.
Vim li cas Thermal Management Deserves More Attention
Ib qho ntawm LED zaub kev ua tau zoo uas pab pawg tsim khoom virtual qee zaum saib tsis pom yog qhov cua sov. Lub ntim LED tuaj yeem ua haujlwm tsis tu ncua rau kaum ob mus rau kaum rau teev nyob rau hauv ib hnub tsim khoom, thiab cov txee zaum hauv ib puag ncig studio nrog cov cua tsis tshua muaj. Nyob rau hauv cov xwm txheej no, cov qauv thermal tsis zoo ua rau cov xim hloov pauv thiab txo qhov sib xws uas ua rau XR theem siv tau rau kev siv.
Lub teeb yuag aluminium txee tsim nyob ib feem ntawm qhov kev sib tw no los ntawm kev txhim kho qhov sib piv ntawm thaj chaw saum npoo rau huab hwm coj, uas ua kom yooj yim rau cov cua sov hloov mus deb ntawm kev tsav tsheb hluav taws xob. Tshaj li tus qauv tsim, qhov zoo ntawm cov pob qij txha zoo, qhov teeb tsa ntawm lub hwj chim faib pawg thawj coj saib, thiab qhov ceev ntawm cov cua sov- ua txoj hauv kev txhua qhov ua rau lub vaj huam sib luag coj li cas tom qab txuas ntxiv ua haujlwm.
Xaiv Txoj Cai Tso Cai rau Kev Tsim Kho Virtual
Cov chaw tsim khoom tsim khoom thiab cov neeg sib koom ua ke soj ntsuam cov khoom siv LED rau XR ib puag ncig tau txais txiaj ntsig los ntawm kev tsim qauv rau cov txheej txheem xaiv. Ntau dua li pib nrog tus nqi lossis kev lees paub ntawm lub npe, cov pab pawg paub txog yuav pib nrog cov txheej txheem kev ua tau zoo: qhov tsawg kawg nkaus refresh npaum li cas, qhov pom tau zoo sib xws delta, xim gamut lub hom phiaj, thiab qhov siab tshaj plaws tso cai pixel suab rau lub koob yees duab npaj siab - mus rau - phab ntsa nrug.
Los ntawm qhov ntawd, thov tus neeg sawv cev rau cov qauv coj mus kuaj thiab ua lub koob yees duab tua- tawm thoob plaws ntau tus neeg sib tw tau ua pov thawj muaj txiaj ntsig ntau dua li kev tshuaj xyuas cov ntaub ntawv hauv kev sib cais. Cov neeg tsim khoom uas txhawb nqa qhov kev ntsuam xyuas zoo li no - muab cov chav qiv nyiaj, kev txhawb nqa kev ntsuas, thiab kev nkag mus rau cov ntaub ntawv kev tshaj lij - zoo li ua kom pom kev nkag siab ntau dua ntawm kev ua haujlwm ntau lawm.
Nyob rau hauv parallel, integrators yuav tsum soj ntsuam lub teeb liab faib architecture uas yuav tsav lub phab ntsa. Latency ntawm qhov chaw ua haujlwm ua haujlwm thiab cov tswj hwm LED, tus lej ntawm cov ntaub ntawv sib txuas yuav tsum tau hais txog thaj tsam tag nrho, thiab kev sib raug zoo ntawm lub cav rendering thiab cov khoom kho vajtse tag nrho cuam tshuam rau daim duab kawg. Lub vaj huam sib luag uas ua tau zoo nyob rau hauv kev sib cais kuj tseem ua tsis tau zoo yog tias lub kaw lus nyob ib puag ncig qhia latency lossis teeb liab degradation.
Ib Daim Ntawv Thov Tam Sim No rau Sab Hauv Tsev LED Zaub Manufacturers
