Txhawm rau xaiv qhov zoo LED xauj tsev, xav txog cov hauv qab no:
1. Muab cov ntsiab lus xav tau
Qhov sib piv ntawm qhov screen yuav tsum tau txiav txim siab raws li cov ntsiab lus yuav tsum tau muab tso tawm. Rau cov ntawv nyeem thiab cov duab, qhov nam piv nyob ntawm cov ntsiab lus. Rau cov ntxaij vab tshaus video, nws feem ntau yog 4: 3 lossis ze rau 4: 3, nrog qhov zoo tagnrho piv yog 16: 9.
2. Cov tsos thiab cov qauv tsim
Tam sim no, nws muaj peev xwm hloov kho cov ntxaij vab tshaus LED raws li kev tsim thiab cov duab ntawm lub tsev. Piv txwv li, tej yaam num classic xws li 2008 Olympic Games, Caij nplooj ntoos hlav Festival Gala, thiab 2021 Lub Caij Ntuj Sov Olympics tau siv LED xauj npo thev naus laus zis kom ua tiav qhov pom tau zoo.
3. Kev Txhim Kho Ib puag ncig yuav tsum tau ua
Siv cov khoom lag luam- qib sib xyaw ua ke chips nrog kev ua haujlwm kub ntawm -40℃txog 80℃los tiv thaiv lub vijtsam xauj tsev ntawm LED tsis pib vim qhov kub tsis tshua muaj thaum lub caij ntuj no. Txhim kho cov cuab yeej ua cua txias kom txias kom txias hauv qhov screen ntawm -10℃thiab 40 degree. Nruab ib lub kiv cua axial saum lub nraub qaum ntawm lub vijtsam kom dissipate cua sov thaum kub siab dhau.
4. Saib qhov nrug thiab pom lub kaum sab xis
Txhawm rau kom pom kev pom ntawm qhov deb ntev hauv lub teeb ci, ultra- siab ci LEDs yuav tsum tau siv. "P" ua raws li tus lej sawv cev rau pixel suab. Tus lej tom qab "P" feem ntau yog hais txog qhov kev ncua deb ntawm pixels nyob rau hauv LED xauj tsev screen module, feem ntau hu ua pixel pitch nyob rau hauv LED xauj screen kev lag luam. Qhov me me no tus nqi, qhov siab dua qhov pixel ceev, qhov pom tseeb ntawm LED xauj npo zaub, thiab qhov zoo dua nws yog rau ze - ntau yam saib. Yog li ntawd, rau cov ntxaij vab tshaus LED, rau qhov luv luv, nws raug nquahu kom siv P2.5 rau P12; rau kev ncua ntev, siv P15; thiab rau qhov ntev ntev, siv cov ntxaij vab tshaus ntawm P16 thiab P25.
Yog tias thaj tsam yog ≥100 square metres thiab qhov pom qhov deb ntau dua 30 meters, nws raug nquahu kom siv lub vijtsam xauj tsev nrog lub pixel pitch ntawm P16 lossis siab dua. Qhov no yog vim cov ntxaij vab tshaus nrog lub pixel pitch ntawm P16 lossis siab dua yog qhov tsim nyog rau cov neeg siv khoom uas tsis xav kom pom tseeb, muaj thaj tsam loj, thiab xav tau tso saib cov duab yooj yim thiab cov yeeb yaj kiab los ntawm qhov deb. Qhov kev ncua deb ntawm qhov pom ntxiv, qhov loj ntawm qhov screen yuav yog. Yog hais tias qhov kev xav kom pom tseeb rau lub vijtsam xauj tsev LED kuj tsawg, koj tuaj yeem xaiv lub vijtsam nrog lub suab pixel loj dua.
Hauv cov ntsiab lus, cov no yog qee yam uas yuav tsum tau xav txog thaum xaiv qhov zoo LED xauj tsev. Ntxiv rau qhov uas tau hais los saum no, peb kuj yuav tsum xav txog qhov load-cov kabmob muaj peev xwm ntawm qhov chaw teeb tsa, qhov ci ntsa iab, qhov pom qhov deb thiab lub kaum sab xis ntawm cov neeg tuaj saib, thiab kev saib xyuas thiab kev pabcuam yav tom ntej. Los ntawm kev noj tag nrho cov xwm txheej no rau hauv kev txiav txim siab, peb tuaj yeem pab koj xaiv qhov zoo tshaj plaws LED xauj tsev.
