Kev tshuaj xyuas ntawm qhov ua rau Blackening ntawm LED Zaub Screens thiab cov kev daws teeb meem sib xws.

Tsab ntawv xov xwm no yuav ua qhov kev ntsuam xyuas qhov tob ntawm cov laj thawj vim li cas LED cov ntxaij vab tshaus tig dub thiab muab qee qhov kev daws teeb meem.

I. Yog vim li cas rau Blackening ntawm LED Zaub Screens

 

Circuit Court Faults
Raws li kev txheeb cais, kwv yees li 30% ntawm cov teeb meem blackening ntawm LED cov ntxaij vab tshaus yog tshwm sim los ntawm cov khoom siv hluav taws xob tsis zoo. Tsis tas li ntawd, teeb liab teeb liab teeb meem cuam tshuam txog li 20% ntawm cov teeb meem blackening ntawm LED cov ntxaij vab tshaus.

Kev laus ntawm LED Chips
LED chips muaj qee yam kev pab cuam lub neej. Nrog rau kev siv sijhawm ntau ntxiv, cov chips yuav maj mam muaj hnub nyoog, nrog rau lawv qhov ci ntsa iab thiab txawm tias puas tag. Feem ntau hais lus, lub neej kev pab cuam ntawm LED chips yog nyob nruab nrab ntawm 50, 000 thiab 100, 000 teev. Txawm li cas los xij, lub neej kev pabcuam tiag tiag yuav raug cuam tshuam los ntawm yam xws li kev siv ib puag ncig thiab ua haujlwm kub. Thaum cov chips muaj hnub nyoog lossis puas lawm, cov dots dub lossis thaj ua rau thaj yuav tshwm rau ntawm lub vijtsam zaub, thiab hauv qhov xwm txheej hnyav, tag nrho cov zaub screen yuav tig dub. Kev laus ntawm LED chips yog ib qho laj thawj tseem ceeb rau blackening ntawm LED cov ntxaij vab tshaus, suav txog li 40% ntawm cov neeg mob.

 

Kev puas tsuaj los ntawm hluav taws xob zoo li qub
Thaum cov txheej txheem ntawm kev tsim khoom, kev teeb tsa, thiab kev saib xyuas, yog tias kev ntsuas tsis zoo li qub tsis tau ua tib zoo, LED chips yuav raug puas los ntawm hluav taws xob zoo li qub. Cov hluav taws xob zoo li qub tuaj yeem ua rau cov chips hauv LED chips puas, ua rau lawv tsis tuaj yeem tawm lub teeb ib txwm. Qhov kev puas tsuaj los ntawm hluav taws xob zoo li qub rau kwv yees li 10% ntawm cov teeb meem blackening ntawm LED cov ntxaij vab tshaus.

 

Faults of Driver Chips
Kev puas tsuaj rau Tsav Chips
Tsav tsheb chips yog cov khoom tseem ceeb uas tswj lub teeb emission ntawm LED chips. Yog hais tias tus neeg tsav tsheb chips malfunction, xws li puas los yog overheating, nws yuav ua rau cov LED chips tsis ua hauj lwm ib txwm, yog li ua rau lub blackening phenomenon ntawm cov zaub screen. Qhov txhaum ntawm tus tsav tsheb chips suav txog li 20% ntawm cov teeb meem blackening ntawm LED cov ntxaij vab tshaus.

 

Tsis ruaj khov tsav tam sim no
Yog tias qhov kev tsav tsheb tam sim no tsis ruaj khov, txawm tias nws siab dhau lossis qis dhau, nws yuav cuam tshuam rau lub teeb emission nyhuv ntawm LED chips thiab tseem ua rau cov chips puas. Kev tsav tsheb tsis ruaj khov tam sim no tuaj yeem tshwm sim los ntawm cov laj thawj xws li lub zog tsis ruaj khov thiab kev ua haujlwm tsis zoo ntawm cov chips tsav tsheb. Kev tsav tsheb tsis ruaj khov tam sim no suav txog li 15% ntawm cov teeb meem blackening ntawm LED cov ntxaij vab tshaus.

 

Environmental Factors
Kub kub
LED cov ntxaij vab tshaus yuav ua kom muaj cua sov thaum lub sijhawm ua haujlwm. Yog tias qhov ntsuas kub ib puag ncig siab dhau lawm, nws yuav ua rau cov cua sov tsis zoo ntawm cov vijtsam zaub, yog li ua rau qhov kub thiab txias ntawm LED chips thiab cov chips tsav tsheb thiab cuam tshuam rau lawv cov haujlwm ib txwm muaj. Ua haujlwm nyob rau hauv qhov chaw kub kub ntev ntev yuav ua rau kev laus thiab kev puas tsuaj ntawm LED chips thiab cov chips tsav tsheb. Feem ntau hais lus, kev ua haujlwm kub ntawm LED cov ntxaij vab tshaus yuav tsum nyob nruab nrab ntawm -20 degree thiab 60 degree . Thaum qhov kub ntawm ib puag ncig siab tshaj 60 degree, qhov tshwm sim ntawm lub vijtsam zaub tig dub yuav nce ntxiv.

 

Cov av noo
Yog tias lub vijtsam LED tso rau hauv qhov chaw ntub dej thiab kev kho dej tsis zoo, nws yuav ua rau lub rooj tsav xwm hauv Circuit Court tau ntub, yog li ua rau muaj teeb meem xws li luv luv Circuit Court thiab corrosion ntawm lub circuits, cuam tshuam rau kev ua haujlwm ntawm cov zaub. npo. Qhov chaw ntub dej suav txog li 10% ntawm cov teeb meem blackening ntawm LED cov ntxaij vab tshaus.

 

II. Cov txheej txheem kom tsis txhob muaj cov ntxaij vab tshaus dub

 

Tsis tu ncua xyuas cov Circuits
Tsis tu ncua xyuas cov khoom siv hluav taws xob thiab cov teeb liab hluav taws xob kom paub tseeb tias cov kev sib txuas hauv Circuit Court ruaj khov thiab tsis muaj teeb meem xws li kev sib cuag tsis zoo, luv luv Circuit Court, lossis qhib circuits.
Rau cov hnub nyoog circuits, lawv yuav tsum tau hloov raws sijhawm kom ntseeg tau tias lub zog ib txwm muaj thiab cov teeb liab kis tau tus mob ntawm lub vijtsam zaub.

 

Hloov cov chips LED puas thiab tsav tsheb chips
Thaum pom tias cov chips LED lossis cov chips tsav tsheb puas lawm, lawv yuav tsum tau hloov tam sim ntawd. Thaum hloov cov chips thiab tsav tsheb chips.

 

Tswj lub Environmental Temperature thiab Humidity
Xyuas kom meej tias lub vijtsam LED ua haujlwm nyob rau hauv ib puag ncig qhov kub thiab txias thiab tsis txhob siv nws nyob rau hauv qhov kub thiab txias ib puag ncig rau lub sijhawm ntev.
Khaws ib puag ncig ib puag ncig ntawm lub vijtsam kom qhuav kom tsis txhob lub vijtsam ntub. Desiccants tuaj yeem muab tso rau ib ncig ntawm lub vijtsam zaub, lossis cov khoom siv dehumidifying tuaj yeem ntsia tau.

 

Siv Cov Kev Ntsuas Anti-static
Hauv pem teb ntawm lub vijtsam zaub kom tsis txhob muaj cov hluav taws xob zoo li qub.

 

Qhov blackening ntawm LED cov ntxaij vab tshaus yog ib qho teeb meem tshwm sim. Yog vim li cas tej zaum yuav muaj xws li Circuit Court faults, kev puas tsuaj rau LED chips, faults ntawm tsav tsheb chips, los yog ib puag ncig yam, thiab lwm yam. Yuav kom tsis txhob blackening ntawm cov zaub screen, cov neeg siv yuav tsum tsis tu ncua xyuas cov circuits, hloov lub puas chips thiab tsav tsheb chips, tswj ib puag ncig. kub thiab av noo, thiab siv cov tshuaj tiv thaiv zoo li qub. Tsuas yog nyob rau hauv txoj kev no tuaj yeem ua haujlwm ib txwm ua haujlwm ntawm LED zaub screen kom ntseeg tau thiab nws lub neej kev pab cuam txuas ntxiv mus.
