I. Ib qho kev nthuav dav ntawm LED Zaub Screens
Ib qho teeb meem ntawm lub teeb-emitting diodes (LEDs) ua ib qho screen LED, uas yog lub vaj huam sib luag vaj huam sib luag. Txhawm rau kom pom cov ntawv nyeem, cov duab, thiab cov yeeb yaj kiab, nws tsim lub teeb nyob rau hauv peb lub ntsiab xim liab, ntsuab, thiab xiav (RGB). Nws muaj cov yam ntxwv tseem ceeb suav nrog kev sib txuas du, siab ci, thiab tus kheej - teeb pom kev zoo.
1.1 Cov Lus Qhia Tseem Ceeb
Pixel: Ua los ntawm ib lossis ntau lub LEDs, lub pixel yog lub teeb me tshaj plaws -emitting unit ntawm ib qho screen.
Pixel Pitch (P-tus nqi): Kev sib cais ntawm cov pixels nyob sib ze (piv txwv li, P1.8). Daim duab yog crisper thaum tus nqi qis dua.
COB Ntim: Tsim nyog rau siab -kawg daim ntawv thov, lub nti yog seamlessly txuas nrog substrate, cuam tshuam -resistant, thiab muaj tshwj xeeb tshav kub dissipation.
Tus naj npawb ntawm lub sij hawm qhov screen refreshes nws cov duab nyob rau hauv ib tug thib ob yog hu ua tus refresh npaum li cas. Flicker yog zam ntawm ntau dua lossis sib npaug rau 3840Hz.
Kev Tiv Thaiv IP: Kev ntsuas dej thiab plua plav, xws li IP65, yog qhov tsim nyog rau kev teeb tsa sab nraum zoov.
II. Common Use Cases for LED Display Screens
LED cov ntxaij vab tshaus tuaj yeem siv rau hauv kev lag luam, tsoomfwv, kev coj noj coj ua, thiab chaw tsim khoom, ob qho tib si sab hauv tsev thiab sab nraum zoov. Siab- cov xwm txheej zaus thiab cov ntsiab lus xaiv suav nrog hauv qab no . 2.1 Cov xwm txheej sab hauv tsev
P1.2–P2.0 me me -pitch COB cov lus qhia nrog cov kev daws teeb meem siab thiab tsis tshua muaj kev cuam tshuam yog qhov zoo tagnrho rau kev sib tham video thiab saib xyuas cov ntaub ntawv hauv chav sib tham thiab cov chaw hais kom ua.
Transparent LED cov ntxaij vab tshaus (70% -90% transmittance), nkhaus mos modules, sib npaug cov duab, thiab spatial pob tshab yog cov yam ntxwv ntawm kev lag luam showrooms thiab khw qhov rais.
2.2 Cov xwm txheej sab nraum zoov
City Landmarks/Advertising Screens: P2.5-P8 sab nraum zoov puv xim cov ntxaij vab tshaus nrog IP65 tiv thaiv, ci ntsa iab yam tsawg kawg 5000cd/㎡, thiab haum rau lub teeb siab thiab ntub dej.
Cov cim hauv nroog
Tsheb thauj mus los Hubs/Cultural Tourism Night Tours: GOB-encapsulated sab nraum zoov cov ntxaij vab tshaus, sib tham sib pem teb pobzeb cov ntxaij vab tshaus, tiv thaiv- cuam tshuam thiab ntev- kav ntev, tsim nyog rau subways thiab keeb kwm lub nroog teeb pom kev zoo.
2.3 Xaiv Cov Table Sib Piv rau Scenarios
| Daim ntawv thov scenarios | Pom zoo P-tus nqi | Cov ntsiab lus tseem ceeb | Kev hloov kho tshuab |
| High- chav sib tham kawg | P1.2-P1.8 | Siab txhais, qis flicker | COB ntim, siab refresh tus nqi |
| Sab nraum zoov advertising screens | P2.5-P5 | High brightness, muaj zog tiv thaiv | IP65, SMD pob |
| Khaws qhov rais | P2.0-P3.0 | High light transmittance, hloov tau | Pob tshab npo, mos module |
| Command Center | P0.9-P1.5 | Seamless splicing, ua haujlwm 24/7 | COB, tsis muaj zog txaus |
III. Cov txiaj ntsig tseem ceeb ntawm LED Zaub
LED qhia ua tiav cov txheej txheem kev tshaj lij thiab kev tso cai ntawm EEAT thiab muab cov txiaj ntsig tseem ceeb ntawm cov lus pom zoo, kev ruaj ntseg, thiab kev ua haujlwm ntev thaum piv rau cov khoom siv pom zoo li LCDs thiab projectors.
3.1 Cov zaub zoo heev
High Brightness thiab Broad Viewing Angle: 170℃wide saib lub kaum ntse ntse, 500–1500 cd/㎡ sab hauv tsev, thiab mus txog 10,000 cd/㎡ sab nraum zoov; yooj yim pom txawm nyob rau hauv lub teeb ci.
Kev Tsim Kho Xim Xim: 10- xim xim qhov tob, xim gamut kev pab them nqi tsawg kawg yog 95%, thiab cov duab zoo nkauj nthuav dav ua rau nws tsim nyog rau cov ntawv thov siab zoo li zaj duab xis thiab tshaj tawm.
3.2 Kev ruaj ntseg ruaj khov thiab txuas ntxiv lub neej
Ntxiv -Long Lifespan: Ntau dua lossis sib npaug li 100,000 teev nyob rau hauv kev ua haujlwm zoo, ntev dua li qhov projectors (20,000 teev) thiab LCDs (50,000 teev).
Strong Environmental Adaptability: Tsim nyog rau kev sib tw kev lag luam thiab sab nraum zoov, nws muaj qhov kub thiab txias ntau yam (-}30℃txog 60 degree), yog plua plav, tsis muaj dej, thiab kev co-resistant.
3.3 Adaptable Personalization thiab Simple Upkeep
Seamless Splicing: Adaptable rau loj thiab irregularly zoo li cov ntxaij vab tshaus, nws tej zaum yuav infinitely spliced mus rau hauv ib tug loj npaum li cas yam tsis muaj lub cev teeb meem.
Kev Txhim Kho Kev Txawj Ntse: Txhawb ib qho - taw tes kom paub qhov tsis xws luag thiab tswj chaw taws teeb; modular tsim txo tus nqi txij nkawm los ntawm kev tshem tawm qhov xav tau los hloov tag nrho lub vijtsam tom qab kho.
3.4 Cov lus sib piv ntawm cov ntsiab lus zoo
| Sib piv Dimensions | LED zaub screen | LCD loj screen | Projector |
| qhov kaj | 500-10000cd / ㎡ | 300-500cd / ㎡ | Tsawg dua lossis sib npaug li 500cd / ㎡ (muaj kev cuam tshuam los ntawm lub teeb pom kev zoo) |
| splicing nyhuv | Seamless splicing, txhua qhov loj | Nws muaj ciam teb, thiab nws qhov loj tshaj plaws yog txwv. | Muaj cov cim ntawm cov duab sib xyaw. |
| Kev pab lub neej | Ntau dua lossis sib npaug li 100,000 teev | Ntau dua lossis sib npaug li 50,000 teev | Ntau dua lossis sib npaug li 20,000 teev |
| Kho nyuaj | Modularization, ib zaug -taw tes tu | Kev kho tshuab ua kom tiav yog tus nqi. | Lub teeb qhov muag tau yooj yim puas thiab yuav tsum tau hloov ntau zaus. |
