Koj yeej tsis xav them cov nqi hluav taws xob ntxiv txhua lub hlis rau koj qhov screen tshaj tawm, txoj cai? Tsis txhob txhawj xeeb, los ntawm kev xaiv raws li cov qauv hauv qab no, koj tuaj yeem muaj qhov tsawg - lub zog tso saib uas tsis txi cov duab zoo thaum txo qis kev siv hluav taws xob ntawm koj lub vijtsam LED, ua rau koj qhov kev tshaj tawm LED tso tawm ntau lub zog-nqi thiab nqi- zoo.
Txoj cai pixel suab yog qhov tseem ceeb rau kev ua tiav lub zog -cov duab LED ua tau zoo.
Qhov me me pixel suab, cov duab pom tseeb dua, tab sis ntau dua qhov kev siv hluav taws xob. Yog tias koj tseem tsis paub meej tias pixel pitch cuam tshuam li cas rau cov duab zoo thiab saib qhov deb, peb "Yuav Ua Li Cas Xaiv Qhov Zoo Tshaj Pixel Pitch" phau ntawv qhia tuaj yeem pab koj nkag siab zoo dua.
Yog tias koj siv nws nyob ze - ib puag ncig saib, xws li chav sib tham, chav tswj, lossis chav ua yeeb yam, koj tuaj yeem xaiv cov khoom uas muaj qhov me me pixel suab. Piv txwv li, P2.5 lossis P3.
Rau kev tshaj tawm sab nraum zoov lossis ntev - saib kev ncua deb, P5 lossis P6 yog qhov tseeb txaus thiab tuaj yeem txo lub zog siv ntawm LED npo.
Lub hauv paus ntawm lub zog- siv tau zoo LED thev naus laus zis yog cov tsav tsheb siab heev.
Tus tsav tsheb nti yog "lub hlwb" ntawm LED zaub, lub luag haujlwm rau kev tswj cov teeb pom kev zoo thiab tam sim no ntawm txhua lub hlaws LED.
Kev lees paub lub zog-ntau tus tsav tsheb nti hom ntawm kev ua lag luam suav nrog: MBI, ICN, Chipone, thiab lwm yam. Cov qauv siv cov chips no feem ntau muaj kev ua tau zoo dua ntawm kev siv hluav taws xob LED.
Kev tswj qhov ci ntsa iab txhawb nqa qis - lub zog zaub hom.
Thaum lub teeb ci ambient dim, yog tias lub vijtsam tseem muaj qhov ci ntsa iab, nws yuav nkim hluav taws xob ntau thiab kuj tseem yuav ua rau cov neeg saib pom dazzling thiab tsis xis nyob.
Los ntawm kev tswj kev ci ntsa iab, LED zaub ib txwm ua haujlwm nyob rau hauv qhov tsim nyog qhov ci ci, tsis txhob siv hluav taws xob tsis zoo thiab yog li ua tiav lub zog - txuag lub hom phiaj ntawm qhov qis - lub zog tso saib.
Lub zog- siv tau LED thev naus laus zis hauv siab - zoo LED modules
Tam sim no, lub zog ntau dua - LED module ntim cov thev naus laus zis hauv kev ua lag luam yog COB (Chip- ntawm- Board) thiab GOB (Glue- ntawm- Board).
COB technology ncaj qha encapsulates LED chips ntawm lub module Circuit Court board, txo qhov kev ncua deb ntawm LED hlaws dai thiab kev twb kev txuas poob, ua tam sim no kis tau tus mob ntau npaum, txo hwj chim noj, thiab kuj txhim kho lub tshav kub dissipation kev ua tau zoo thiab kev cia siab ntawm lub module.
Zog-npaum LED zaub ua kom txias ua kom tsis muaj zog siv.
Yog tias lub vijtsam LED muaj cov cua sov tsis zoo, nws yuav tsis tsuas yog tsim kom muaj cua sov ntau, tab sis kuj "nyem hluav taws xob ntau," uas yuav ua rau muaj nqi ntau heev nyob rau lub sijhawm ntev. Lub zog tiag tiag- cov khoom lag luam LED siv tau zoo feem ntau pib nrog cov cua kub dissipation system rau lub zog-txuag tsim. Cov hauv qab no yog qee qhov kev ua kom sov dissipation. Koj tuaj yeem xaiv txoj kev tsim nyog tshaj plaws raws li koj qhov kev siv scenario:
Passive Txias Technology
Passive txias tsis cia siab rau cov kiv cua, tab sis siv cov ntaub ntawv xws li aluminium alloy casings thiab thermal conductive silicone kom ib txwm ua kom sov. Txoj kev no tsis siv hluav taws xob ntxiv, ua rau muaj kev txuag hluav taws xob tseem ceeb.
Kev ua kom txias txias yog qhov tsim nyog rau qhov chaw nyob sab hauv lossis qis - cov ntxaij vab tshaus fais fab, thiab yog txoj hauv kev ua kom txias siv los ntawm ntau lub zog ib txwm siv -txuag LED cov ntxaij vab tshaus.
Ntse Ntxuam Txias
Rau sab nraum zoov cov ntxaij vab tshaus loj lossis siab - qhov ua haujlwm ci ntsa iab, kev ua kom txias yog qhov tseem ceeb heev. Lub kiv cua ntse tuaj yeem hloov kho nws qhov nrawm raws li qhov kub thiab txias, txias sai sai thaum xav tau thiab nyob twj ywm thaum tsis muaj.
Cov kiv cua txias tsim kom tsis txhob muaj hluav taws xob pov tseg los ntawm cov kiv cua khiav tsis tu ncua, yog li txo qhov kev siv hluav taws xob tag nrho ntawm LED npo.
Kua Cooling System
Kev ua kua dej txias yog qhov siab -qhov kawg txias txoj kev uas sai sai dissipates cua sov los ntawm cov kua ncig. Nws ua haujlwm zoo heev thiab ua haujlwm ntsiag to. Cov kua ua kua txias pab tswj qhov kub ntawm siab - ci ntsa iab, siab - cov ntxaij vab tshaus LED ceev, txuas lawv lub neej, thiab tshwj xeeb tshaj yog tsim rau cov ntxaij vab tshaus loj loj lossis qis - lub zog tshuaj ntsuam kev daws teeb meem hauv qhov chaw tshwj xeeb.
