LED大屏跟傳統(tǒng)的電子產(chǎn)品一樣，在使用過程中不僅需要注意方法，還需對顯示屏進行保養(yǎng)維護，才能使LED大屏壽命更久。這里常彩電子就為大家來分析下保養(yǎng)LED全彩大屏幕的幾種方法。 </p> <p> 1、保持全彩LED大屏使用環(huán)境的濕度，不要讓任何具有濕氣性質(zhì)的東西進入全彩LED大屏。對含有濕度的全彩LED大屏加電，會導(dǎo)致全彩LED大屏零部件腐蝕，進而造成長久性損壞。 </p> <p> 2、要避免可能碰到的問題，我們可以選擇被動防護與主動防護，盡量把可能對全彩LED大屏造成傷害的物品遠離屏幕，而清潔屏幕的時候也盡可能輕輕地擦拭，把傷害的可能性降到很<span style="display:none;"></span>小。 </p> <p> 3、LED全彩d<span style="display:none;"></span>與我們用戶的關(guān)系<span style="display:none;"></span>為密切，綿陽拼接大屏，做好清潔維護工作也是非常有必要的。長時間暴露在戶外環(huán)境風(fēng)吹、日曬、灰塵等易顯臟，綿陽拼接大屏，一段時間下來，屏幕上肯定是灰塵一片，這需要及時清洗以防塵土長時間包裹表面影響觀看效果。 </p> <p> 4、要求供電電源穩(wěn)定，并接地保護良好，綿陽拼接大屏，在惡劣的自然條件特別是強雷電天氣下不要使用。 </p> <p> <br /> LED大屏作為一種戶外媒體發(fā)揮著極其重要的作用，不僅可以起到商業(yè)照明的作用，而且還可以作為廣告屏。綿陽拼接大屏</p><div style="width:100%;text-align: center;"><img

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。綿陽拼接大屏戶外LED大屏的確能給城市形象帶來一定的提升，廣告形式也靈活多樣。</p><div

1.避雷器安裝在led大屏和建筑物上 </p> <p> 顯示屏的主體和外殼應(yīng)良好接地，接地電阻應(yīng)小于3歐姆，顯示屏可能受到雷電引起的強電和強磁的沖擊，以便及時釋放雷電引起的大電流. </p> <p> 2.戶外led大屏安裝的防水措施 </p> <p> led大屏安裝及屏體與建筑物連接處必須嚴格防水、防漏;屏體應(yīng)有良好的排水措施，一旦積水，能順利排出;注意防水、防潮。顯示屏安裝在室外，常有陽光、雨水、風(fēng)塵覆蓋，工作環(huán)境惡劣。如果電子設(shè)備被弄濕或嚴重受潮，會引起短路甚至火災(zāi)，引起故障甚至火災(zāi)，并造成損失。在LED 大屏的使用中，高鐵媒體的受眾定位在高頻商旅，他們作為家庭中堅力量，具有較強的品牌意識。南充戶外大屏批發(fā)價格</p><p style="text-indent:25px">戶外LED大屏，采用高科技背板散熱、點陣光源發(fā)光進行統(tǒng)一的管理，更加利于LED大屏的使用。綿陽拼接大屏</p><p> 5.發(fā)光管的視角 </p> <p> 發(fā)光管的發(fā)光視角是指觀察方向的亮度下降到LED大屏法線方向亮度的二分之一時，同一平面兩個觀察方向與法線方向所成的夾角。分為水平視角和垂直視角。 </p> <p> 對于戶外LED大屏一般使用橢圓發(fā)光管或者貼片發(fā)光管，橢圓發(fā)光管具有角度小、亮度高等特點，而貼片發(fā)光管的垂直視角要遠大于橢圓管，但其亮度要小于橢圓發(fā)光管，從使用者的角度來說應(yīng)根據(jù)LED大屏的受眾面及周邊的光環(huán)境來選擇不同視角的發(fā)光管。對于室內(nèi)LED大屏因其亮度要求低，受眾面一般較廣，所以貼片發(fā)光管是比較好的選擇。需要說明的是，現(xiàn)在市場有部分發(fā)光管的制造商為降低成本，迷惑使用者，把發(fā)光管的亮度做得比較高，而視角做得比常規(guī)的發(fā)光管視角小，這會導(dǎo)致LED大屏正面看亮度非常高，但是側(cè)面比較大的角度觀看就出現(xiàn)看不清圖像的情況。小尺寸的LED芯片為了提高亮度，通常采用小角度的封裝。大尺寸的不需要小角度封裝，因為不需要那么高的亮度。所以，大角度(110)高亮度低電流才是比較好的。綿陽拼接大屏</p><p
