Lub zog yuav tsum tau ua rau sab hauv LED me me -pitch screen yuav tsum tau xam raws li qhov screen loj, pixel ceev, lub zog noj ib pixel, thiab kev ua haujlwm hom. Cov mis yog: Kev Xav Tau Lub Hwj Chim=Qhov Loj × Pixel Density² × Kev Siv Hluav Taws Xob rau Pixel × Kev Ua Haujlwm Hom Coefficient. Ib qho kev ntsuam xyuas ntxaws nram qab no:
Screen Size: Qhov loj ntawm qhov screen, qhov siab dua qhov yuav tsum tau muaj zog. Piv txwv li, lub vijtsam 2-square-meter yuav tsum muaj lub zog loj dua li 1-square-meter screen.
Pixel Density: Qhov me me ntawm pixel suab (ntau dua), pixels ntau dua ib chav tsev, ua rau muaj zog dua. Pixel density yuav xam tau siv cov mis 1/Pixel Pitch² (unit: pixels/square meter). Piv txwv li, ib qho screen nrog 2 hli pixel suab muaj pixel ceev ntawm 250,000 pixels / square meter.
Kev siv hluav taws xob ib Pixel: Cov txiaj ntsig tshwj xeeb yuav tsum tau txais los ntawm daim ntawv qhia LED nti, feem ntau yog li ntawm 0.1W txog 0.5W / pixel. Kev siv hluav taws xob tuaj yeem sib txawv nyob ntawm cov xim (liab, ntsuab, xiav); rau tag nrho -xim npo, lub zog noj yuav tsum raug xam raws li qhov sib npaug ntawm peb xim.
Kev ua haujlwm hom coefficient: Kho raws li lub vijtsam kev ua haujlwm, feem ntau ntawm 0.5 (50% ci ntsa iab) thiab 1 (100% ci ntsa iab). Piv txwv li: Static zaub (taw duab): coefficient ze rau 1; Dynamic zaub (video lossis scrolling ntawv): coefficient yuav txo mus rau 0.7; Zog-txuag hom (tsawg ci): coefficient tuaj yeem qis li 0.3.
Piv txwv kev suav: Piv txwv li 2-square-meter LED me-pitch screen nrog cov tsis muaj hauv qab no:
Pixel suab: 2 hli → Pixel ceev=1/(0.002)²=250,000 pixels/square meter;
Lub zog noj ib pixel: 0.3W (qhov nruab nrab ntawm peb xim rau tag nrho -xim npo);
Kev khiav hauj lwm hom coefficient: 0.8 (80% brightness).
Hloov mus rau hauv cov qauv: Lub zog yuav tsum muaj=2㎡ × 250,000 pixels/㎡ × 0.3W/pixel × 0.8=120,000W (120kW). Nco tseg: Cov nqi tiag tiag yuav tsum tau hloov kho raws li cov kev txwv tshwj xeeb; qhov piv txwv no tsuas yog ua kom pom qhov kev xam pom. Cov kev ceev faj:
Fais fab Efficiency thiab Kab Poob: Qhov tseeb fais fab mov yuav tsum siab tshaj qhov xam tus nqi; pom zoo 20% margin. Piv txwv li, yog tias tus nqi suav yog 100kW, xaiv lub hwj chim ntawm tsawg kawg yog 120kW.
Segmented Power Supply: Rau cov ntxaij vab tshaus loj, segmented fais fab mov yog pom zoo kom tsis txhob overloading ib lub hwj chim mov. Piv txwv li, faib lub vijtsam rau hauv plaub qhov chaw, txhua tus muaj nws tus kheej lub zog ywj pheej.
Kev Sib Tham Kev Sib Tham: Hu rau cov khoom siv hluav taws xob lossis cov chaw tsim khoom lag luam, muab cov kev txwv tshwj xeeb (xws li lub vijtsam loj, pixel suab, thiab qhov ci ntsa iab) rau cov lus pom zoo.
Cov ntsiab lus: Lub zog yuav tsum muaj rau sab hauv tsev me me -pitch LED cov ntxaij vab tshaus yuav tsum tau suav nrog kev siv cov qauv, suav nrog kev ua haujlwm tiag tiag. Kev xaiv raug yuav tsum tau xav txog cov kev txwv tshwj xeeb; nws raug pom zoo kom sab laj cov kws tshaj lij cov tuam txhab ua ntej kom muaj kev nyab xeeb thiab ua haujlwm zoo.
