Koj puas npaj yuav nruab ib lub siab - brightness sab nraum zoov LED advertising screen rau koj lub lag luam? Thaum cov neeg yuav khoom tsom mus rau qhov pib tus nqi tau los, lawv feem ntau saib xyuas cov nuj nqis ua haujlwm tsis tu ncua. Cov ntxaij vab tshaus anode ib txwm ua kom muaj cua sov ntau dhau, degrade pixels ntxov ntxov, thiab siv zog ntau heev.
Hmoov zoo, kev hloov pauv thev naus laus zis tseem ceeb yog daws qhov teeb meem thermal no. Hauv phau ntawv qhia no, peb yuav txheeb xyuas vim li cas sab nraum zoov LED cov ntxaij vab tshaus overheat thiab piav qhia yuav ua li cas siv lub zog cathode-txuag thev naus laus zis tuaj yeem txo koj cov nqi hluav taws xob mus txog 50% thaum txo koj lub nra hnyav.
Tus nqi zais ntawm tshav kub nyob rau sab nraum zoov LED cov ntxaij vab tshaus
Sab nraum zoov LED cov ntxaij vab tshaus yuav tsum tso tawm qhov ci ci siab tshaj -feem ntau tshaj 6,000 mus rau 10,000 nits- kom pom nyob rau hauv lub hnub ncaj qha. Txawm li cas los xij, tsim lub teeb ci no yuav tsum muaj hluav taws xob tam sim no.
Nyob rau hauv ib txwm siv anode LED tsim, ob qho tib si liab, ntsuab, thiab xiav (RGB) LED chips tau txais cov khoom siv hluav taws xob tsis zoo (feem ntau 5V lossis 4.2V). Vim tias cov nti liab tsuas yog xav tau txog 2.8V los ua haujlwm, qhov seem voltage converts ncaj qha rau hauv khib nyiab. Qhov kev kub ntxhov no ua rau muaj ntau yam teeb meem kev ua haujlwm tseem ceeb:
- Accelerated Pixel Degradation: Tshaj kub ua kom luv lub neej ntawm LED diodes, ua rau tsis sib xws xim hloov thiab dimming.
- Tsav IC Failure: Kub kub degrade cov khoom siv hluav taws xob ntawm lub tsav tsheb IC, ua rau cov pixels tuag thiab kho kim.
- Cov nqi cua txias siab: Lub tshuab cua txias lossis cua tshuab yuav tsum khiav tas li kom cov zaub ua haujlwm tau zoo, ua rau koj cov nqi hluav taws xob ob npaug.
Common Anode vs Common Cathode Technology
Txhawm rau kom nkag siab yuav ua li cas tshem tawm cov khib nyiab no, peb yuav tsum tshuaj xyuas cov khoom siv hluav taws xob sab hauv. Cov lus hauv qab no sib piv cov txheej txheem anode ib txwm siv nrog cov tshuab cathode siab heev.
| Feature / Metric | Ib txwm Common Anode LED Screen | Common Cathode Energy-Txuag LED Screen |
|---|---|---|
| Fais fab faib | Ib lub hwj chim mov channel rau RGB chips | Kev ywj pheej fais fab mov channels (Dual{0}}Voltage) |
| Voltage muab | Uniform 5.0V / 4.2V rau liab, ntsuab, thiab xiav | Liab: 2.8V|Ntsuab & Xiav: 3.8V |
| Thaum tshav kub kub Dissipation | Tsis tshua muaj siab (Vasted voltage hloov mus rau hauv tshav kub) | Tsawg (Tsis muaj qhov hluav taws xob rov ua dua lossis lub zog khib nyiab) |
| Kev siv fais fab | 100% kev siv lub hauv paus | Txo los ntawm 30% mus rau 50% |
| Nruab Nrab Lifespan | 50,000 teev (vim thermal stress) | 100,000 teev (khiav txias) |
| Kev Xav Tau Kev Kho Mob | Ntau zaus pixel hloov & kho kiv cua | Kev tu me me nrog cov kiv cua tsis muaj txhuas |
Los ntawm routing ywj siab, optimized voltages ncaj qha mus rau txhua xim nti, ib tug cathode tshuab ua kom ntseeg tau tias tsis muaj hluav taws xob hloov mus rau hauv tsis muaj cua sov. Qhov no txo qis kev ua haujlwm kub ntawm lub txee kom txog li 15 degree.
3 Lub Tswv Yim Tseem Ceeb rau Xaiv Koj Cov Duab Sab Nraud Tom ntej
Thaum soj ntsuam cov chaw muag khoom thiab tab tom nrhiav rau sab nraum zoov LED advertising npo uas lav qhov siab tshaj plaws ROI, ua tib zoo mloog peb cov ntsiab lus kho vajtse:
- Hais rau Dual-Cov Khoom Siv Hluav Taws Xob: Tshawb xyuas nrog cov chaw tsim khoom tias lawv cov khoom siv hluav taws xob (PSUs) faib cov hluav taws xob tawm hluav taws xob dynamically. Lub kaw lus cathode uas muaj tseeb yuav tsum muaj dual -channel configuration.
- Xaiv rau Aluminium Tuag-Cabinets: Aluminium ua cua sov zoo dua li cov khoom siv hlau. Siv lub tsev zoo aluminium tso cai rau kev tsim tsis muaj kiv cua, tiv thaiv plua plav thiab ya raws.
- Xav tau IP66 Kev tiv thaiv pem hauv ntej thiab nram qab: Txij li thaum cov ntxaij vab tshaus sab nraum zoov ua rau huab cua hnyav, muaj lub kaw lus kaw tag nrho nrog ob lub- kev saib xyuas kev nkag (pem hauv ntej thiab nram qab) txo qis sijhawm.
Xaus: Ua tam sim no kom txo koj cov TCO
Ua kom koj cov nyiaj rov qab los ntawm kev nqis peev ntau tshaj plaws yuav tsum xaiv cov zaub uas sib npaug siab - cuam tshuam cov duab nrog tus nqi qis ntawm cov tswv cuab (TCO). Kev siv tshuab cathode ib txwm muab qhov txias - khiav, kev txhim khu kev qha zoo uas txuag koj ntau txhiab daus las hauv cov nqi hluav taws xob thiab cov khoom hloov pauv.
