Lub zog noj qhov sib txawv ntawm P1.2 thiab P1.5 LED qhia feem ntau yog nyob ntawm cov khoom tshwj xeeb tsim thiab teeb tsa, es tsis yog qhov pixel suab. Raws li tib yam kev mob, P1.2 feem ntau siv zog me ntsis ntau dua P1.5, tab sis qhov sib txawv tiag tiag yuav tsawg heev.
1. Core Power Consumption Sib txawv
Pixel pitch nws tus kheej tsis ncaj qha txiav txim siab siv hluav taws xob, tab sis vim tias P1.2 muaj qhov siab dua pixel ntom ntom (kwv yees li 694,444 dots / ㎡), nws muaj ntau lub teeb pom kev zoo -emitting ntsiab lus thaum pom cov ntsiab lus ci tib yam, theoretically ua rau lub zog siab dua me ntsis ntau dua li P1.5 (kwv yees 44 ㎡). Txawm li cas los xij, qhov sib txawv ntawm lub zog siv hluav taws xob feem ntau yog tswj tsis pub dhau 10% -20%, nyob ntawm cov khoom siv thev naus laus zis thiab qib kev ua kom zoo.
2. Cov ntsiab lus tseem ceeb cuam tshuam rau kev siv hluav taws xob
• Nominal Power: Xa mus rau cov qauv tshwj xeeb cov lus qhia tshwj xeeb. Piv txwv li, lub hom P1.2 npo tuaj yeem muaj lub zog siab tshaj plaws ntawm 800W / ㎡, thaum tib lub koob 'P1.5 yuav muaj 700W / ㎡.
• LED Luminous Efficiency: Siv high -kev ua tau zoo LED chips (xws li COB ntim tshuab tshiab) txo qis kev siv hluav taws xob rau tib lub teeb ci; tus qauv P1.2 tshiab kuj tseem yuav muaj zog ntau dua -ntau dua li tus qauv P1.5 qub.
• Tus Tsav Tsheb Ua Haujlwm Zoo: Siab- cov khoom siv hluav taws xob zoo ua tiav cov txiaj ntsig kev hloov pauv ntau dua 90%, txo qis zog.
• Thermal Design: Ib qho kev ua kom sov zoo (xws li tooj liab yeeb nkab thaum tshav kub kub + cua txias) tsis txhob luminous efficiency degradation thiab ntxiv zog noj vim overheating.
• Cov ntsiab lus thiab Dimming: Kev siv hluav taws xob siab tshaj plaws thaum ua si puv -dawb, siab - cov yeeb yaj kiab brightness; enabling dynamic dimming yuav txo tau lub hwj chim noj los ntawm 30%-50% . 3. Piv txwv kev siv fais fab
Noj 10㎡ zaub screen ua haujlwm rau 10 teev txhua hnub ua piv txwv:
- Yog P1.2 hwj chim yog 750W/㎡: Kev siv hluav taws xob txhua hnub=10 × 750 × 10 ÷ 1000=75 kWh
- Yog P1.5 fais fab tuag yog 650W/㎡: Kev siv hluav taws xob txhua hnub=10 × 650 × 10 ÷ 1000=65 kWh
Cov nqi hluav taws xob tiag tiag yuav tsum tau suav nrog raws li cov nqi hluav taws xob hauv zos. Thaum muaj hluav taws xob hluav taws xob yog kwv yees li 0.8 yuan / kWh, tus nqi hluav taws xob niaj hnub rau P1.2 yog kwv yees li 8 yuan siab dua li ntawm P1.5.
4. Cov lus pom zoo yuav khoom
Ua ntej cov khoom lag luam uas qhia txog kev ntsuas kev siv hluav taws xob los yog muab cov ntaub ntawv ntsuas kev siv hluav taws xob. Lub teb chaws tus qauv tshiab GB 30255-2019 tau muab qhab nia raws li qhov yuav tsum tau ua rau LED zaub screen zog efficiency. Rau siab -cov ntxaij vab tshaus ntom ntom, ua tib zoo saib seb cov chaw tsim khoom puas siv cov thev naus laus zis txuag hluav taws xob xws li cov cathode drives. Cov thev naus laus zis no tuaj yeem txo qis kev khiav hauj lwm voltage, yog li txo qhov tsim hluav taws xob thiab siv hluav taws xob.
