Meta Description:Dab tsi yog qhov kev daws teeb meem coj teeb pom kev zoo thiab qhov piv txwv ua haujlwm li cas? Kawm yuav ua li cas format koj cov ntsiab lus video zoo kawg nkaus kom tsis txhob ncab cov duab.
Taw qhia
Thaum saib mus rau hauv dab tsi yog ib qho LED zaub, ntau tus neeg xav tias kev teeb tsa ib qho zoo ib yam li kev yuav lub chaw ua haujlwm saib xyuas lossis TV hauv tsev. Txawm li cas los xij, vim tias cov ntxaij vab tshaus no tau tsim los siv cov vaj huam sib luag modular, lawv tsis tas li ua raws li cov qauv kev daws teeb meem lossis cov duab. Kev nkag siab tias pixel suav thiab nam piv ua haujlwm li cas hauv ib puag ncig modular yog qhov tseem ceeb rau kev tsim cov kws tshaj lij, kev cuam tshuam - cov ntsiab lus tsis pom kev.
Deconstructing Resolution nyob rau hauv Modular Displays
Kev daws teeb meem yog hais txog tag nrho cov naj npawb ntawm cov pixels thoob plaws kab rov tav thiab ntsug ntawm ib qho screen, feem ntau yog sau raws li qhov dav x qhov siab (xws li $ 1920 \\times 1080$).
Ntawm tus qauv siv TV, qhov kev daws teeb meem yog ua ntej - txiav txim siab los ntawm lub Hoobkas iav vaj huam sib luag. Ntawm phab ntsa LED, txawm li cas los xij, qhov kev daws teeb meem yog nyob ntawm qhov pixel pitch ntawm cov modules thiab tag nrho lub cev loj ntawm lub vijtsam sib dhos. Yog tias koj ntxiv cov txee ntxiv rau qhov dav ntawm koj lub vijtsam, koj cov kab rov tav pixel suav yuav nce.
Qhov no txhais tau hais tias LED zaub tuaj yeem muaj qhov kev daws teeb meem tsis zoo, xws li $ 1440 x 810 $ lossis $ 2300 x 1150 $. Cov neeg tsim cov ntsiab lus yuav tsum paub txog qhov ntev npaum li cas los xyuas kom meej tias cov duab tau muab pixel-rau-pixel, tiv thaiv qhov muag plooj lossis jagged npoo.
Demystifying Aspect Ratios
Qhov sib piv yog qhov sib piv ntawm qhov dav thiab qhov siab ntawm lub vijtsam, qhia tias yog ob tus lej sib cais los ntawm txoj hnyuv ($ W: H$).
Tus Qauv 16: 9 Widescreen Ratio
Feem ntau cov ntsiab lus video niaj hnub no, tshaj tawm hauv TV, thiab kev nthuav qhia koom nrog yog tsim nyob rau hauv a16:9 piv(tus qauv widescreen hom rau siab -cov lus txhais thiab cov ntsiab lus video). Yog tias koj tsim koj lub phab ntsa modular kom phim qhov piv txwv no, cov ntaub ntawv video txheem yuav sau lub vijtsam zoo kawg nkaus yam tsis muaj cov kab dub lossis ncab.
Unconventional thiab Custom Shapes
Vim hais tias cov vaj huam sib luag kaw ua ke dawb, koj tuaj yeem tsim cov duab hauv ultra-kev teeb tsa dav dav ($ 32: 9$) lossis ntsug ntauwd layouts ($ 9: 16$). Thaum cov duab zoo li no zoo nkauj hauv khw muag khoom lossis kev teeb tsa vaj tsev, lawv xav tau kev cai- tua lossis tshwj xeeb kho cov ntsiab lus video kom ntseeg tau tias cov duab tsis tshwm sim tsis zoo los yog txiav tawm ntawm ciam teb.
Cov lus qhia rau kev sib piv cov ntsiab lus rau Screen Shape
Txhawm rau kom tsis txhob muaj teeb meem tshwm sim thaum muaj xwm txheej tshwm sim lossis kev tshaj tawm txhua hnub, pawg ntsiab lus yuav tsum nkag siab tias qhov sib txawv ntawm qhov sib txawv li cas:
Letterboxing:Muaj tshwm sim thaum lub yees duab dav tau ua si ntawm lub vijtsam nqaim, ua rau cov kab dub tshwm rau saum thiab hauv qab.
Pillarboxing:tshwm sim thaum lub yees duab nqaim (zoo li lub xov tooj smartphone) ua si ntawm lub vijtsam dav, tsim cov kab dub ntawm sab laug thiab sab xis.
Stretching / Distortion:Muaj tshwm sim thaum tus neeg siv xov xwm yuam cov ntaub ntawv video los sau lub vijtsam nrog qhov sib txawv ntawm qhov sib txawv, ua rau tib neeg thiab cov duab zoo li tsis zoo li dav lossis siab.
Kev daws teeb meem yooj yim
Txhawm rau qhia seb lub cev qhov loj me thiab pixel pitches cuam tshuam li cas rau qhov kev daws teeb meem, xav txog cov kev teeb tsa ntawm phab ntsa modular:
| Lub cev phab ntsa Dimensions | Pixel Pitch siv | Qhov kev daws teeb meem tag nrho | Qhov txiaj ntsig Aspect Ratio |
| Kwv yees li $4\\text{m} \\times 2.25\\text{m}$ | P2.5 | $1600 x 900$ pixels | Zoo meej 16: 9 Widescreen |
