Kev siv lub TV neeg siv khoom siv rau kev lag luam voids lub chaw tsim khoom warranty. Cov pab pawg muag khoom feem ntau pom qhov no tom qab qhov thib ob lossis thib peb hloov pauv -los ntawm qhov taw tes lawv "pob nyiaj" cov kev daws teeb meem twb dhau tus nqi ntawm ib lub vaj huam sib luag lag luam.
Tus nqi sib txawv ntawm $ 300 tus neeg siv TV thiab $ 1,200 kev lag luam LCD vaj huam sib luag zoo li tseem ceeb ntawm kev yuav khoom. Ntawm daim ntawv spec, qhov sib txawv zoo li me me: tib qhov kev daws teeb meem, qhov loj me ntawm lub vijtsam, ob leeg thov LED backlighting. Qhov kev sib cais tiag tiag tshwm sim nyob ib puag ncig lub hlis kaum plaub, thaum cov neeg siv khoom- qib qhia ua haujlwm kaum ob teev txhua hnub hauv qhov chaw muag khoom pib ua tsis tiav lossis txo qis pom pom. Kev lag luam vaj huam sib luag tau tsim kho rau 50,000 txog 100,000 teev ntawm kev ua haujlwm tas mus li-tab sis tus lej ntawd suav tias yog kev teeb tsa thiab kev tswj xyuas thermal, uas yog qhov feem ntau ntawm kev xa mus tsis raug.
Qhov twg Engineering yeej txawv
Qhov ci ntsa iab qhia tsuas yog ib feem ntawm zaj dab neeg. Cov neeg siv khoom vaj huam sib luag feem ntau tso tawm 200-300 nits; coj mus muag- qib LCD zaub vaj huam sib luag rau cov khw muag khoom pib ntawm 400-700 nits rau kev siv sab hauv tsev thiab ncav cuag 2,500-5,000 nits rau kev teeb tsa lub qhov rais. Thaum tav su lub hnub tsoo koj lub khob iav, qhov no tsis yog hais txog kev zoo nkauj - nws yog seb cov neeg siv khoom tuaj yeem nyeem koj tus nqi txhua.
Kev tswj cua sov tsim qhov sib cais tiag tiag. Thaum peb ntsuas qhov chaw teeb tsa, thawj lo lus nug tsis yog qhov screen loj - nws yog airflow. LED hlws ris kub siab tshaj 85℃txiav luminous efficiency los ntawm 3-5% ib qho ntxiv 10 degree. Kev lag luam vaj huam sib luag hais qhov no nrog cov tuab aluminium kub dissipation backplates; Cov neeg siv khoom skimp ntawm no vim kev siv hauv tsev yeej tsis thawb cov kev txwv thermal. Hauv qhov chaw muag khoom kaw nrog HVAC tsis zoo, qhov sib txawv no txiav txim siab seb koj cov zaub dub tawm thaum lub caij ntuj sov lub sijhawm.
Muaj cov lus qhia tshwj xeeb feem ntau cov neeg yuav khoom tsis tau ntsib: Tni, nematic -isotropic hloov pauv kub. Thaum lub vaj huam sib luag kub siab tshaj qhov pib no, cov pob dub loj loj tshwm ntawm qhov screen. Kev lag luam- qib kev lag luam LCDs siv siab-Tni kua siv lead ua kua tsim tshwj xeeb vim qhov rais- ntsib cov khw muag khoom hauv cov huab cua kub yuav thawb cov qauv vaj huam sib luag dhau los ntawm lawv cov kev txwv hauv thawj lub caij ntuj sov.
ROI: Qhov twg cov lej los ntawm cov teeb meem
A 30-cov khw muag tshuaj uas peb tau ua haujlwm nrog hauv Midwest tau taug qab 11% nqa ntawm cov khoom txhawb nqa hauv thawj peb lub hlis twg-nrog cov ntsiab lus hloov pauv txhua lub lim tiam thiab tso rau ntawm kev xa tawm. Lub khw muag khoom nrawm nrawm nrog ob zaug ntawm qhov screen suav pom xoom ntsuas qhov cuam tshuam vim tias cov ntsiab lus tshaj tawm tsis tau hloov kho tom qab lub lim tiam. Tib yam khoom kho vajtse, sib txawv cov txiaj ntsig.
Lub sijhawm them rov qab rau cov khw muag khoom digital signage feem ntau poob ntawm 8 thiab 18 lub hlis thaum tswj cov ntsiab lus tseem ceeb. Cov kev hloov pauv uas viav vias qhov ntau: kev hloov pauv tus nqi (cov khw muag khoom yooj yim xav tau ntau dua kev yuav khoom dua li cov khw muag khoom rooj tog kom muaj kev cuam tshuam nyiaj duas las), cov txheej txheem kev tsim khoom (ntsuas nqa ntawm cov khoom txhawb nqa pom tau tias feem pua ntawm cov khw muag khoom muag tag nrho qhia me ntsis ib tus lej), thiab kev qhuab qhia tshiab.
25-35% kev koom tes nce ntxiv hauv cov ntawv tshaj tawm kev lag luam sawv cev rau kev xa tawm qhov twg ib tus neeg tswj hwm cov ntsiab lus. Peb hais txog 8-15% raws li kev npaj kev xav rau cov neeg siv khoom uas tsis tau npaj siab cog lus rau cov ntsiab lus kev sib hloov-nws yog kev saib xyuas, thiab nws tseem xaum tawm hauv ob xyoos rau feem ntau cov khw muag khoom hneev taw.
Tsib -Xyoo TCO: Tus lej uas kaw qhov kev sib tham
| Nqi Element | Cov neeg siv khoom TV | Kev lag luam LCD |
|---|---|---|
| Pib kho vajtse | $300/unit | $1,200/unit |
| Kev hloov pauv ntau dua 5 xyoos | 2-3 units + zog | 0 |
| 5-xyoo tus nqi kho vajtse | $1,100-1,800 | $1,200 |

Lub vaj huam sib luag ua lag luam raug nqi tsawg dua hauv txhua qhov xwm txheej uas koj tab tom khiav cov ntxaij vab tshaus ntau dua rau teev ib hnub. Thaum yim- teev ua haujlwm, qhov kev sib tw yuav tshwm sim nyob ib ncig ntawm lub hli 30. Thaum kaum ob teev, nws yog lub hli 18. Peb tau tso tseg cov neeg siv khoom hloov pauv rau txhua tus neeg siv kev npaj tshaj li 24- lub hlis xa mus rau lub qab ntug-lub nra ntawm kev txhawb nqa ib leeg tsis tsim nyog rau cov paj.
Installation Failures Peb yeej pom
Rau caum feem pua ntawm peb cov kev pabcuam hu hauv thawj 90 hnub taug qab rau kev teeb tsa, tsis yog kho vajtse. Feem ntau: cov tswv yim tawm tswv yim tsis sib haum uas cov neeg tsim khoom txuas HDMI mus rau qhov chaw nres nkoj 2 thiab teeb tsa cov media player rau qhov chaw nres nkoj 1. Cov ntawv sau cov chaw nres nkoj ntawm kev teeb tsa tshem tawm pawg no tag nrho. Peb tam sim no suav nrog cov ntaub ntawv pov thawj chaw nres nkoj raws li tus qauv xa tuaj tau - nws tsis raug nqi dab tsi thiab txiav cov kev pabcuam thaum ntxov hauv ib nrab.
Kev npaj hluav taws xob hluav taws xob tsis zoo yuav luag feem ntau nyob rau hauv ib puag ncig retrofit. Kev lag luam- qib lcd signage qhia kos 2.5-4.5 amps ib chav nyob ntawm qhov ci tag nrho. Chain plaub qhia mus rau 15A Circuit Court yam tsis suav cov khoom siv siab tshaj plaws thiab koj tau txais kev cuam tshuam tsis sib xws uas zoo li kho vajtse tsis ua haujlwm tab sis tsis yog. NEC hluav taws xob code qhia txog 80% qhov siab tshaj plaws thauj khoom-ib qho tshwj xeeb uas AV integrators ua raws tab sis cov neeg cog lus tsis tu ncua tsis tu ncua thaum "tsuas yog ntxiv ob peb lub vijtsam."
Thermal spacing tau overlooked nyob rau hauv nruj khw muag khoom ib puag ncig. Peb tau sau cov lus qhia ua tsis tiav ntawm 18 lub hlis uas yuav tsum tau siv sijhawm xya xyoo, tag nrho vim kev txiav txim siab txuas ntxiv kom txuag tau plaub nti ntawm qhov chaw hauv pem teb. Peb qhov chaw ntsuas tus qauv tam sim no suav nrog kev ntsuas cua sov thaum lub sijhawm ua haujlwm siab tshaj -ib kauj ruam ntxiv uas tiv thaiv peb qhov kev tsis sib haum xeeb hauv xyoo dhau los ib leeg.
Tus neeg muab khoom Ecosystem: Qhov Peb Pom Zoo
