Raws li qhov nruab nrab tseem ceeb rau cov ntaub ntawv niaj hnub no, cov lus qhia LED sab hauv tsev tau siv dav hauv kev tshaj tawm kev lag luam, cov rooj sib tham, cov chaw soj ntsuam, thiab lwm yam kev lag luam vim lawv qhov zoo xws li lub teeb ci siab, qhov sib txawv siab, lub neej ntev, thiab kev hloov kho. Raws li qhov sib txawv ntawm cov kev tsis sib txawv thiab kev siv cov xwm txheej, cov khoom siv sab hauv LED tuaj yeem muab faib ua pawg hauv qab no.
1. Kev faib tawm los ntawm Pixel Pitch
Pixel pitch yog qhov taw qhia tseem ceeb ntawm LED cov lus qhia, xa mus rau qhov kev ncua deb ntawm LEDs uas nyob ib sab thiab cuam tshuam ncaj qha rau qhov pom tseeb. Feem ntau sab hauv tsev LED zaub muaj xws li:
- Zoo-pitch LEDs (hauv qab P1.5):Xws li P1.2 thiab P1.5, muab siab pixel ceev thiab tsim nyog rau kev saib ze. Lawv feem ntau siv nyob rau hauv siab - chav sib tham kawg, chav tswj, thiab chav ua yeeb yam khoom kim heev.
- Tsis tu ncua -pitch LEDs (P2-P5):Xws li P2.5, P3, thiab P4, muab tus nqi siab - ua tau zoo thiab tsim nyog rau cov khoom lag luam dav dav, lub rooj txais tos neeg, thiab chaw kawm.
- Loj -pitch LEDs (P6 thiab siab dua):Xws li P6 thiab P8, haum rau ntev - saib deb lossis pob nyiaj siv - txwv tsis pub muaj xwm txheej, xws li cov tsev hais lus loj.
2. Kev faib tawm los ntawm txoj kev ntim khoom
- SMD (Nto Mount Ntaus):Siv thev naus laus zis saum npoo av, LEDs tau teeb tsa rau ntawm PCB, ua rau muaj qhov sib xws. Haum rau nruab nrab - thiab siab - cov lus qhia ceev, tam sim no nws yog qhov kev daws teeb meem loj.
- COB (Coupling on Board):LED chips yog ntsia ncaj qha rau ntawm PCB, muab kev tiv thaiv zoo dua, suav nrog kev cuam tshuam zoo heev thiab tiv thaiv- cov khoom zoo li qub. Haum rau cov ntawv thov uas xav tau kev ruaj ntseg siab.
3. Kev faib tawm los ntawm Kev Siv Ua Haujlwm
- Rental Displays:Cov qauv tsim qauv tso cai rau kev teeb tsa sai thiab tshem tawm, ua rau lawv tsim nyog rau theem ua yeeb yam thiab kev nthuav qhia.
- Fixed Displays:Cov qauv ruaj khov tso cai rau ntev -lub sij hawm, ruaj khov- siv cov ntawv thov, xws li cov khw muag khoom kos npe thiab cov rooj sib tham hauv chav sib tham.
Ntau hom LED sab hauv tsev muaj lawv tus kheej zoo. Cov neeg siv tuaj yeem xaiv cov kev daws teeb meem tsim nyog raws li lawv cov kev xav tau tshwj xeeb kom ua tiav cov duab zoo thiab tus nqi -kev ua tau zoo.
