<p> 2.關(guān)屏：首先關(guān)掉LED屏體電源，關(guān)掉控制軟件，再正確的關(guān)閉計算機;(先關(guān)計算機不關(guān)LED大屏，會造成屏體出現(xiàn)高亮點，燒毀燈管，后果嚴(yán)重) </p> <p> 3.開關(guān)屏?xí)r間隔時間要大于5分鐘; </p> <p>

選用工作溫度-40～80℃的工業(yè)集成電路芯片，防止冬季溫度過低而導(dǎo)致顯示屏啟動 </p> <p> 4.戶外LED大屏安裝通風(fēng)設(shè)備降溫，使屏體內(nèi)部溫度在-10℃～40℃之間。 </p> <p> 戶外LED大屏體背后上方安裝軸流風(fēng)機排出熱量;顯示屏工作時本身就要產(chǎn)生一定的熱量，如果環(huán)境溫度過高而散熱又不良，集成電路可能工作不正常，甚至被燒毀，從而使顯示系統(tǒng)無法正常工作 </p> <p> 5.戶外LED大屏必須選用超高亮度發(fā)光二極管 </p> <p> 為了保證強光下的遠距離可視性，需要選擇超高亮度發(fā)光二極管;增加對比度;觀眾面廣、視距長、視野寬;環(huán)境光變化大，特別是可能的直射光。 </p> <p> 6.戶外LED大屏顯示介質(zhì)選用新型廣視角管 </p> <p> 寬視角、純色、協(xié)調(diào)一致、壽命超過100000小時的顯示介質(zhì)包裝，為目前流行的帶遮沿方形筒體、硅膠密封、非金屬組裝;其外形精美、耐用、具有陽光直射、防塵、防水、耐高溫、短路五大防功能 </p><p> 一、局部“死燈”問題 </p> <p> 局部“死燈”是指LED大屏的燈面上有一顆或者幾顆燈不亮，這種不亮區(qū)分為全時不亮和部分顏色不亮，一般這種情況是燈本身出現(xiàn)了問題，要么是受潮，要么是RGB芯片損壞，我們維修的方法很簡單，就是用工廠配的LED燈珠備品換上即可，那么使用的工具就是鑷子，換上備品LED燈珠以后，用測試卡重新測試一遍，沒有問題就是已經(jīng)修好了。 </p> <p> 二、“毛毛蟲”問題 </p> <p> “毛毛蟲”只是一個比喻的說法，系指LED大屏在通電條件下而沒有輸入源的時候，部分燈面出現(xiàn)一長條的暗亮條的現(xiàn)象，且以紅色居多。出現(xiàn)這種現(xiàn)象的根本原因是燈內(nèi)部芯片漏電，或者背后的IC面行管線路短路，前者為大多數(shù)。一般出現(xiàn)這種情況，我們只需要拿著熱風(fēng)機沿著漏電的這一條變色“毛毛蟲”吹熱風(fēng)，當(dāng)吹到有問題的那顆燈，一般就OK了，因為受熱使得內(nèi)部漏電的芯片連接澎開了，但是仍然存在隱患，我們只需要找到漏電的那顆LED燈珠，按照上面講到的方法，把這顆隱患燈珠換掉就OK。如果是背后IC面的行管線路短路，就需要使用萬用表具體測量一下相關(guān)的IC針腳電路，換一顆新的IC即可。戶外LED大屏不但兼具創(chuàng)作的藝術(shù)性，更是作為商業(yè)、品牌傳播的重要門戶，這種媒體形式極具營銷價值和品質(zhì)。</p><div

一：整屏打出白色，屏幕應(yīng)該是純白色，沒有任何其它雜色。如果您認(rèn)為有一點偏紅或者偏藍，就證明顯示屏材料和工藝質(zhì)量控制等都有問題。使用時間久了，會越來越嚴(yán)重。 </p> <p> 二：打出紅、綠、藍單色，中心波長的顏色就是平時我們說的正藍正紅正綠，如果深一點或者淺一點的顏色，證明是偏波長。如果某一顏色不一致，證明是波差太大，LED大屏在中心波長的范圍內(nèi)，藍綠波差控制在3nm，紅色波差小于5nm。 LED大屏照明已逐步運用到家庭的日常生活當(dāng)中，LED大屏不但提升了城市形象。長沙 LED大屏供應(yīng)商</p><p

2.如清潔模組表面，請使用軟毛刷，輕輕刷拭。禁止使用任何液體物質(zhì)清洗LED模組表面，否則LED燈珠有可能損壞; </p> <p> 3.正確擦拭：LED大屏大屏幕表面可以采用酒精進行擦拭，或者使用毛刷、吸塵器進行除塵，不能直接用濕布擦拭。 </p> <p> LED大屏防潮及存儲要求 </p> <p> 1、存儲溫度要求：環(huán)境溫度-40℃≤t≤60℃，包裝打開后，LED產(chǎn)品須存放在溫度<30℃和濕度<60%環(huán)境中; </p> <p> 2、根據(jù)顯示屏體、控制部分所處環(huán)境情況，避免蟲咬，必要時應(yīng)放置防鼠藥; 長沙 LED大屏供應(yīng)商</p><p
