Vim hais tias sab nraum zoov LED cov ntxaij vab tshaus loj tau teeb tsa sab nraum zoov thiab feem ntau loj loj, cov tswv yuav tsum nkag siab qee cov ntaub ntawv tseem ceeb ua ntej kho thiab txhim kho sab nraum zoov LED loj screen.
Cov yam ntxwv tseem ceeb los txiav txim siab thaum kho thiab txhim kho sab nraum zoov LED lub vijtsam loj suav nrog: pixel pitch, daws teeb meem, refresh npaum li cas, qib greyscale, pom cov nyhuv, kev ua haujlwm ntawm cov khoom, dej tsis zoo thiab noo noo- pov thawj muaj peev xwm, thiab cov khoom siv zog.
Pixel pitch ncaj qha cuam tshuam rau cov zaub thiab saib cov nyhuv ntawm sab nraum zoov LED lub vijtsam loj, yog li cov tswv yuav tsum txiav txim siab qhov tsim nyog pixel suab qauv. Feem ntau, sab nraum zoov puv - xim LED zaub muaj qhov pom ntev dua, feem ntau pib los ntawm 8 meters, yog li qhov tsim nyog pixel suab yog 6mm-8mm, piv txwv li, P6-P8 specifications rau sab nraum zoov LED zaub khoom.
Kev daws teeb meem yog hais txog cov pixels uas cov zaub tuaj yeem pom. Txij li cov ntsiab lus, kab, thiab qhov chaw ntawm lub vijtsam yog tag nrho cov pixels, ntau pixels cov zaub tuaj yeem pom, cov duab yuav zoo dua, thiab cov ntaub ntawv ntau tuaj yeem tso tawm hauv tib cheeb tsam. Yog li ntawd, kev daws teeb meem yog qhov qhia txog kev ua tau zoo heev. Qhov kev daws teeb meem ntawm sab nraum zoov LED loj npo yog feem ntau cuam tshuam nrog cov lus qhia tshwj xeeb thiab qhov loj ntawm lub vijtsam zaub.
Refresh tus nqi yog hais txog qhov ceev ntawm cov duab hloov tshiab ntawm qhov screen, uas yog, tus naj npawb ntawm cov duab tshwm ntawm qhov screen ib ob. Qhov siab dua qhov refresh npaum li cas ntawm LED zaub, qhov ruaj khov ntawm cov duab pom, thiab qhov muag pom tsawg dua. Feem ntau, qhov pom kev ua kom pom tseeb tshaj 3000Hz qhia tau hais tias muaj -kev ua tau zoo LED zaub.
