Cov neeg yuav khoom yav tom ntej feem ntau sib piv pixel pitch, ci ntsa iab thiab refresh npaum li cas, ces nres nyeem daim ntawv spec. Kev siv fais fab - feem ntau luam tawm hauv lub rooj me me raws li "max zog" - tsis tshua tau txais qhov thib ob. Qhov ntawd yog to taub txog thaum thawj daim nqi hluav taws xob tuaj txog, thaum lub sijhawm cov lej ntawm nplooj ntawv pib muaj teeb meem loj.
Cov teeb meem pib tam sim ntawd, vim tsis muaj ib lo lus teb ncaj ncees rau "lub zog npaum li cas lub vijtsam no siv?" Ib qho zaub muaj tsawg kawg yog peb lub zog sib txawv, thiab lawv tsis yog tib yam:
- Peak (qhov siab tshaj) lub zog- qhov teeb meem phem tshaj plaws yog tias txhua pixel teeb ntawm tag nrho dawb, siab tshaj plaws ci. Yuav luag yeej tsis tshwm sim hauv cov ntsiab lus tiag.
- Lub zog nruab nrab- tus tsim khoom kwv yees raws li cov ntsiab lus tshaj tawm, feem ntau yog 30-50% ntawm qhov siab tshaj. Tseem optimistic rau ntau scenes.
- Qhov tseeb ntsuas lub zog- Dab tsi koj ntsuas pom tom qab lub vijtsam raug teeb tsa, khiav koj cov ntsiab lus tiag ntawm koj qhov chaw tiag.
Kev yuav cov kev txiav txim siab raws li lub zog siab tshaj plaws yuav overestimate tus nqi los ntawm ob mus rau peb zaug; kev txiav txim siab raws li cov chaw tsim khoom nruab nrab tsuas tuaj yeem kwv yees lawv tsis zoo.
Qhov yooj yim xam
Cov lej yog yooj yim thaum koj muaj qhov tseeb wattage:
Lub zog txhua hnub (kWh)=nruab nrab lub zog (kW) × cov sij hawm ua haujlwm Lub hli tus nqi=ib hnub kWh × 30 × koj cov nqi (ib kWh)
Ua piv txwv.Lub 100 m² sab nraum zoov tsau zaub nrog lub ncov kos ntawm 800 W / m² thiab qhov tseeb qhov nruab nrab ntawm 35% ntawm ncov (280 W / m²):
- 0.28 kW/m² × 100 m²=28 kW nruab nrab load
- Ua haujlwm 12 h / hnub: 336 kWh / hnub → roughly 10,000 kWh / hli
- Ntawm US0.12/kWh:∗∗ txogUS0.12/kWh: **kwv yees US0.12/kWh:∗∗ txog US1,200 ib hlis**
Hloov cov kev xav thiab daim nqi hloov pauv sai sai: cov ntsiab lus uas feem ntau tsaus nti es tsis txhob ci, lossis qhov hloov pauv qhov ci ntsa iab uas txo cov zis thaum hmo ntuj, tuaj yeem txiav kev ntsuas ntsuas los ntawm 30% lossis ntau dua. Common-cathode tsav tsim thiab niaj hnub txuag hluav taws xob tsav ICs txo nws ntxiv ntawm qib kho vajtse.
Dab tsi tiag txav tus lej
Cov ntsiab lus brightness ..Ib qho tag nrho-dawb puv npo thav duab raug nqi ntau zaus ntau dua li qhov tsaus nti feem ntau. Rau kev tshaj tawm cov ntxaij vab tshaus no yog qhov sib txawv loj tshaj plaws, thiab nws yog tswj los ntawm leej twg tsim cov tswv yim - tsis yog los ntawm kho vajtse. Ib lub ntsej muag dub-tom qab muaj tswv yim nrog cov ntawv ci ci yog ob qho tib si zoo nkauj thiab pheej yig dua los khiav.
Lub sijhawm ua haujlwm thiab lub sijhawm ci ntsa iab ..Ob lub vijtsam zoo ib yam hauv tib lub nroog tuaj yeem sib txawv 40% ntawm tus nqi txhua hli tsuas yog vim tias ib qho khiav 24/7 ntawm qhov kaj nruab hnub ruaj khov thaum lwm tus siv lub teeb pom kev zoo thiab hmo ntuj.
Pixel suab thiab LED suav.Ntau LEDs txhais tau tias ntau lub zog kos ib square meter ntawm qhov sib npaug. Fine-pitch sab hauv cov ntxaij vab tshaus khiav ntawm qhov qis qis dua li cov ntawv tshaj tawm sab nraum zoov, yog li P1.5 lub rooj sib tham phab ntsa tuaj yeem haus tsawg dua ib m² dua li P10 sab nraum zoov npo, txawm tias muaj 44 npaug ntawm pixels.
Tsav technology.Common-cathode designs, qis tsav tam sim no teeb tsa thiab cov khoom siv hluav taws xob muaj txiaj ntsig txhua qhov kev sib tw hauv paus. Tsis muaj ib nrab ntawm daim nqi ntawm lawv tus kheej, tab sis ua ke lawv sib xyaw.
Ib puag ncig.Lub hnub ci ncaj qha ua rau lub teeb ci siab; qhov chaw ntxoov ntxoo los yog sab qaum teb tsis yog. Kev tso kawm cuam tshuam rau daim nqi hluav taws xob ntau npaum li daim ntawv spec ua.
Daim ntawv txheeb xyuas ua ntej yuav khoom
- Nug tus neeg muag khoom rau ob qho tib si ncov thiab nruab nrab noj cov nuj nqis, thiabua li casqhov nruab nrab yog xam (cov ntsiab lus dab tsi, qhov ci ntsa iab).
- Thov ntsuas cov ntaub ntawv lossis kev siv los ntawm qhov sib piv tau teeb tsa qhov project es tsis lees txais kev kwv yees.
- Muab ntau los ntawm koj cov nqi se thiab cov sijhawm ua haujlwm tiag tiag - tsis yog tus lej lej.
- Xws li cov khoom cua txias: nyob rau hauv ib qho chaw nyob sab hauv tsev los yog lub thawv-raws li sab nraum zoov tsim, cov cua txias xav tau los tshem tawm cov cua sov tuaj yeem ntxiv 15-25% rau tag nrho cov kev siv zog.
- Nug seb lub teeb pom kev ci ntsa iab, hmo ntuj dimming lub sijhawm thiab kev sib koom-cathode tsav puas txaus siab - cov no yog cov levers koj yuav tswj tau tom qab kev teeb tsa.
Qhov takeaway
Kev siv hluav taws xob tsis yog cov lus hauv qab; Tshaj li tsib xyoos kev ua neej nyob, hluav taws xob tuaj yeem sib tw muaj txiaj ntsig ntawm qhov screen tus nqi yuav khoom rau ib txwm nyob rau sab nraum zoov. Qhov xwm zoo yog tias feem ntau ntawm kev txuag tau los ntawm kev txiav txim siab uas tsis muaj nqi dab tsi: tsim cov ntsiab lus tsim nyog, lub sij hawm ci ntsa iab ncaj ncees, thiab nug cov lus nug zoo ua ntej kos npe rau daim ntawv xaj. Ib qho screen uas tau teev tseg nrog cov nuj nqis tiag tiag tsis yog pheej yig dua los khiav - nws tseem yooj yim dua los npaj kev teeb tsa hluav taws xob rau, uas yog ib qho ntawm feem ntau underestimated qhov chaw ntawm txhua qhov project LED.
