1. Pixel suab
Pixel pitch hais txog qhov kev ncua deb ntawm qhov nruab nrab ntawm ob lub pixels uas nyob ib sab ntawm ib qho LED zaub, ntsuas hauv millimeters (mm). Cov pixel pitches feem ntau suav nrog P1.2, P1.5, P1.86, P2.5, P3, P4, thiab lwm yam. Ib qho pixel me me ua rau muaj kev daws teeb meem ntau dua thiab cov duab zoo dua, tab sis kuj yog tus nqi siab dua.
Thaum xaiv cov zaub, qhov tsim nyog pixel pitch yuav tsum raug xaiv raws li qhov pom qhov deb hauv chav sib tham. Feem ntau, qhov pom kev deb (meters) yog kwv yees li 1.5 mus rau 3 npaug ntawm pixel suab (mm). Piv txwv li, lub vijtsam P2.5 yog qhov tsim nyog rau kev saib qhov deb ntawm 3.75 txog 7.5 meters, thiab lub vijtsam P3 yog qhov tsim nyog rau kev saib deb ntawm 4.5 txog 9 meters. Yog tias lub vijtsam nrog lub suab loj pixel raug xaiv rau qhov pom luv luv, pom pom pixelation yuav tshwm sim, cuam tshuam rau kev pom; conversely, xaiv ib qho screen nrog ib tug me me pixel suab rau ib tug ntev saib nyob deb yuav ua rau tsis tsim nyog cov nqi.
2. Tus nqi refresh
Lub refresh npaum li cas yog hais txog tus naj npawb ntawm lub sij hawm lub vijtsam refreshes cov duab ib ob, ntsuas hauv Hertz (Hz). Lub siab refresh tus nqi tau zoo zam lub vijtsam flickering thiab cov lus tsa suab plooj, ua rau cov duab dynamic smoother. Tshwj xeeb tshaj yog thaum tua thiab kaw cov ntsiab lus ntawm lub rooj sib tham, qhov kev hloov tshiab siab tuaj yeem tiv thaiv cov qauv moiré. Tam sim no, lub rooj sib tham tseem ceeb hauv chav LED zaub muaj qhov hloov tshiab ntawm 3840Hz lossis siab dua, ua tau raws li qhov xav tau ntawm ntau yam siab -txhais video playback thiab cov ntaub ntawv ceev ceev.
3. Xim Gamut Kev Pabcuam
Xim gamut kev pab them nqi yog hais txog ntau yam xim uas lub vijtsam tuaj yeem tso tawm . 16.7 lab xim gamut kev pabcuam txhais tau tias lub vijtsam tuaj yeem tso saib ntau yam xim nrog cov xim raug siab, ua siab ncaj qhia txog cov duab qub. Thaum xaiv cov zaub, ua tib zoo saib seb lub vijtsam puas ua tau raws li cov qauv xim gamut xws li DCI-P3 lossis sRGB kom ntseeg tau tias cov xim muaj tseeb.
4. Kev kho qhov ci ntsa iab
Lub ci ci kev ua haujlwm tso cai rau lub vijtsam tuaj yeem hloov kho nws qhov ci ntsa iab raws li kev hloov pauv ntawm lub teeb nyob ib puag ncig. Cov chav sablaj muaj teeb pom kev zoo; Qee lub sij hawm lub teeb muaj zog, thiab qee zaum qhov chaw tsaus yog xav tau rau qhov projection. Ib qho LED zaub nrog lub ci ci kev ua haujlwm tuaj yeem tswj xyuas cov teeb pom kev zoo hauv cov teeb pom kev sib txawv thaum tsis txhob qhov muag pom los ntawm lub teeb muaj zog. Feem ntau, qhov ci ntawm sab hauv LED cov ntxaij vab tshaus loj ntawm 500 txog 1500 cd / m², thiab tuaj yeem hloov kho raws li qhov xav tau tiag tiag.
