Kev sib piv ntawm LCD thiab LED zaub rau sab nraum zoov kos npe
Qhia Txog Kev Siv Tshuab: Cov Duab Tsim los ntawm Txhua Cov Zaub
Kev nkag siab txog qhov sib txawv ntawm LED thiab LCD zaub pib ntawm qib tivthaiv. Lub vaj huam sib luag ua kua nrog LED backlight yog siv hauv LCD (Liquid Crystal Display) los tsim cov duab. Cov kua siv lead ua kua tuaj yeem thaiv lossis tso cai rau lub teeb los ntawm lub teeb hauv qab kom ntws los ntawm; lawv tsis tsim teeb rau lawv tus kheej. Vim li no, dab tsi tib neeg hu ua "LED TV" yog qhov tseeb LCD nrog LED backlights es tsis yog qhov tseeb LED zaub.
Tus kheej lub teeb-emitting diodes yog siv los ua tus kheej -emitting pixels ncaj qha- saib cov duab LED, tseem hu ua dvLEDs. Tsis tas yuav muaj lub teeb pom kev zoo, cov kua nplaum ua kua, lossis cov xim xim vim tias txhua pixel tsim nws lub teeb. Txhua qhov kev ua tau zoo uas tseem ceeb rau kev siv sab nraum zoov yog txiav txim siab los ntawm qhov sib txawv ntawm cov qauv no -backlit piv rau tus kheej -emissive.
Cov ntsiab lus tseem ceeb:
Zaub brightness yog ntsuas nyob rau hauv candelas ib square meter (cd/m2), los yog nits.
Pixel suab: Cov millimeters uas cais cov chaw ntawm cov pixels nyob sib ze; lub suab qis qhia tau hais tias qhov kev daws teeb meem siab dua.
Kev ntsuam xyuas IP: Kev tiv thaiv Ingress uas qhia txog kev tiv thaiv dej thiab plua plav (piv txwv li, IP65=dej dav hlau tiv thaiv thiab plua plav- nruj)
Kev Ua Haujlwm Sab Nraud: Qhov Sib Txawv ntawm Cov Tshuab
Brightness thiab Readability nyob rau hauv tshav ntuj
Qhov ci ntsa iab heev yuav tsum tau nyob hauv qhov chaw sab nraum zoov. Nyob rau hauv tshav ntuj ncaj qha, ib qho khoom siv sab hauv tsev ua haujlwm ntawm 350-500 nits, ua rau nws ze li pom. Rau siab - cuam tshuam qhov pom, sab nraum zoov LED cov tshuab feem ntau tshaj 5,000 nits, thiab ntau yam txawm txog 10,000 nits. Qhov ci ntsa iab LCD vaj huam sib luag muaj qhov ci siab tshaj plaws ntawm kwv yees li 3,500 nits, uas tseem qis dhau rau ntau qhov puv - hnub ci.
| Brightness Metric | LCD zaub | LED zaub |
|---|---|---|
| Tej yam nyob hauv tsev brightness | 350-700 hli | 1,200-2,000 nits |
| Tej yam sab nraum ci | 1,000–3,500 nits (siab- qauv ci ntsa iab) | 5,000-10,000 nits |
| Hnub ci nyeem tau | txwv; yuav tsum tau shading | Zoo heev; pom nyob rau hauv lub hnub ncaj qha |
| Saib nrug | Qhov zoo tshaj plaws nyob ze | Pom tau los ntawm ntau pua meters |
Kev ua tau zoo ntawm qhov sib txawv thiab xim
LCDs cia siab rau lub teeb rov qab uas yog ib feem ntawm txawm tias lub vijtsam dub, uas ua rau lub teeb pom kev zoo uas txo qis qhov sib piv thiab nce qib dub. LCDs tsis tuaj yeem tswj lub teeb ntawm qib pixel, txawm tias muaj qhov dimming hauv zos. Txhawm rau tsim cov xim dub ntshiab, uas muaj qhov sib txawv zoo dua, cov xim zoo nkauj dua, thiab cov duab ntxoov ntxoo tob tob, LED zaub pixels kaw tag nrho. Rau kev tshaj tawm sab nraum zoov, qhov twg cov khoom yuav tsum ci tawm tsam lub teeb ci ambient, qhov no yog qhov tseem ceeb heev.
Sturdiness thiab Resistance rau huab cua
Sab nraum zoov LCD cov ntxaij vab tshaus yog nkig thiab yooj yim rau ib puag ncig kev puas tsuaj. Direct- saib cov duab LED muaj zog dua los ntawm qhov xwm txheej, nrog cov qauv uas tuaj yeem zam qhov kub hnyav, siv hnyav, thiab sab nraum zoov. IP65 lossis IP66 weatherproofing, uas tiv thaiv cov plua plav, nag, thiab cov dav hlau dej muaj zog, yog qhov zoo ntawm cov khoom siv sab nraum zoov LED pom zoo.
Kev siv tswv yim: Thaum xaiv Txhua Tshuab
LCD cov ntxaij vab tshaus tseem yog qhov kev xaiv zoo rau:
Cov ntawv qhia zaub mov thiab kos npe hauv cov khw muag khoom sab hauv
Kaw -kom pom qhov twg siab pixel ceev yog qhov tseem ceeb
Kev teeb tsa sab hauv tsev ntawm kev siv nyiaj nruj
Cov ntawv thov uas me dua 100 ntiv tes thiab ua qhov tseem ceeb rau kev daws teeb meem ib square meter
Sab nraum zoov LED cov ntxaij vab tshaus yog superior hauv:
DOOH (Digital Out-ntawm-Tsev) kev tshaj tawm thiab cov ntawv tshaj tawm digital
Scoreboards hauv chaw ntau pob thiab arenas
Lub nroog squares thiab tsheb thauj mus los hubs
Loj - hom video phab ntsa uas xav tau du, bezel -dawb nto
Txhua daim ntawv thov raug tshav ntuj hnyav lossis huab cua tsis zoo
Case Study: Digital Billboard ntawm Sheikh Zayed Road hauv Dubai
INFiLED muab nws cov MVmk2 Series rau qhov tseem ceeb DOOH qhov chaw ntawm Dubai's Sheikh Zayed Road, lub nroog txoj kev loj tshaj plaws uas muaj ntau tshaj 500,000 tus neeg hla txhua hnub, hauv ib qho kev xav tau tshaj plaws sab nraum zoov LED teeb tsa hauv Middle East.
Kev teeb tsa suav nrog 300 m² LED zaub nrog 10.4mm pixel suab uas tuaj yeem tsim txog li 10,000 nits ntawm qhov ci, lav cov duab nkig, muaj zog txawm tias thaum nruab hnub. Piv nrog rau cov khoom siv sab nraum zoov LED, IP65-rated zaub ua tiav 16% txo qis hauv nruab nrab siv hluav taws xob ua tsaug rau nws cov kiv cua tsim thiab zoo heev tshav kub dissipation.
Cov teeb meem kev ntseeg tau yog tus tsav tsheb tom qab qhov hloov pauv, raws li Pixels World, Emirati DOOH kev lag luam khiav lub xaib. Lub vijtsam ua ntej tau dhau los ua kom sov, ua rau muaj zog thiab daws teeb meem. Kev tsim tsis muaj kiv cua ntawm MVmk2 txo qhov ntev - cov nqi kho mob los ntawm kev ua kom deb ntawm qhov xav tau ntxiv cua txias lossis qhov cua. Los ntawm conception mus rau installation, qhov project tau tiav nyob rau hauv ib ncig ntawm 12 lub lis piam.
Qhov piv txwv no qhia tau tias yog vim li cas sab nraum zoov LED zaub technology yog tam sim no mus - rau kev xaiv rau siab - pom kev tshaj tawm nyob rau hauv hnyav qhov chaw uas LCD lwm txoj kev tsuas yog tsis mus txog par.
FAQ
Puas yog LED zaub tiag tiag tib yam li "LED TV"?
Tsis yog. Qhov tseeb, feem ntau ntawm cov neeg siv khoom "LED TVs" yog LCD cov ntxaij vab tshaus nrog LED backlighting. Tsis muaj lub teeb pom kev zoo lossis cov kua siv lead ua kua dej, qhov ncaj qha ncaj qha - saib LED zaub siv ib tus neeg LEDs ua pixels.
Puas muaj peev xwm siv cov ntxaij vab tshaus LCD sab nraud?
Yog, txawm li cas los xij muaj ntau qhov txwv. Txawm hais tias lawv tuaj yeem ua haujlwm hauv qhov chaw ntxoov ntxoo sab nraum zoov, siab -cov qauv teeb ci LCD (1,000–3,500 nits) xav tau cov ntaub thaiv npog, tsim kom muaj cua sov ntau dua, thiab muaj lub neej ntev dua.
Dab tsi ntawm qhov ci ci yuav tsum tau rau sab nraum zoov kos npe?
1,500–2,500 nits rau qhov chaw sab nraum zoov nrog ntxoov ntxoo . 2,500–5,000+ nits rau raug tshav ntuj ncaj qha. Cov qauv no feem ntau dhau los ntawm sab nraum zoov LED zaub.
Dab tsi yog qhov lifespan ntawm sab nraum zoov LED zaub?
Thaum LCD panels muaj lub neej kev pab ntawm 30,000-50,000 teev thaum siv sab nraum zoov, sab nraum zoov LED zaub feem ntau muaj kev pab cuam lub neej ntawm 80,000-100,000 teev.
