style="font-size:14px;">在專業(yè)LED廠家維修之前，建議從三個(gè)方面自檢：</span> </p> <p> <span style="font-size:14px;">1，產(chǎn)品質(zhì)量不過關(guān)。在購(gòu)買的時(shí)候不要貪圖便宜去購(gòu)買價(jià)格低質(zhì)量差的產(chǎn)品。</span> </p> <p> <span style="font-size:14px;">2，電壓不穩(wěn)定。造成漏電的現(xiàn)象。</span> </p> <p> <span style="font-size:14px;">3，操作方法不當(dāng)，由人為的操作錯(cuò)誤，影響顯示屏的效果。</span> </p> <p> <span style="font-size:14px;">那么應(yīng)該怎么去檢查呢？</span> </p> <p> <span style="font-size:14px;">第壹，判斷電源有沒有損壞，還能不能正常使用。因?yàn)橐粋€(gè)電源同時(shí)控制著幾塊單元板。可以測(cè)量一下輸出電壓是否在4.9~5.5v之間。不在這個(gè)范圍內(nèi)的話，很可能是電源壞了。</span> </p> <p> <span style="font-size:14px;">第二，檢查控制卡是不是正常使用。先把電源打開，看下控制卡指示燈是否點(diǎn)亮；如果不亮，則檢查一下是否有5V電壓供電，LED電子屏能不能顯示內(nèi)容，如果能顯示內(nèi)容，說明控制卡顯示內(nèi)容功能是好的；然后再用控制卡軟件查找一下控制卡，如果能查找的到的話，則說明控制卡發(fā)送內(nèi)容的功能良好；如果查找不到，則檢查一下通訊線有沒有接好，如果接好了，就很有可能是卡出問題了，昆明小間距LED顯示屏。只要這兩個(gè)功能良好，控制卡就是好的，昆明小間距LED顯示屏，否則就要更換控制卡了。</span> </p> <p> <span style="font-size:14px;">第三，查看單元板是不是好的，昆明小間距LED顯示屏。LED顯示屏的信號(hào)都是從一個(gè)板傳送到另一個(gè)板的輸入。所以有一塊板出問題的話，都會(huì)影響到后面的板。所以要逐一去檢查單元板是否正常。</span> 原材料對(duì)LED顯示屏價(jià)格的影響。昆明小間距LED顯示屏</p><div

style="font-size:14px;">一、港口、車站旅客引導(dǎo)信息顯示</span> </p> <p> <span style="font-size:14px;">以LED顯示民間為主體的信息系統(tǒng)和廣播系統(tǒng)、列車到發(fā)揭示系統(tǒng)、票務(wù)信息系統(tǒng)等共同構(gòu)成客運(yùn)樞紐的自動(dòng)化系統(tǒng)，成為國(guó)內(nèi)火車站和港口技術(shù)發(fā)展和改造的重要內(nèi)容。</span> </p> <p> <span style="font-size:14px;">二、體育場(chǎng)館信息顯示</span> </p> <p> <span style="font-size:14px;">LED顯示屏作為比賽信息顯示和</span><span style="font-size:14px;">比賽實(shí)況播放的的主要手段已取代了傳統(tǒng)的燈光及CRT顯示屏，在現(xiàn)代化體育場(chǎng)館成為必備的比賽設(shè)施。</span> </p> <p> <span style="font-size:14px;">三、道路交通信息顯示</span> </p> <p> <span style="font-size:14px;">智能效通系統(tǒng)的興起，在城市效通、高速公路等領(lǐng)域，LED顯示民間作為可變情報(bào)板、限速標(biāo)志等，得到普遍采用。</span> </p> <p> <span style="font-size:14px;">四、調(diào)度指揮中心信息顯示</span> </p> <p> <span style="font-size:14px;">電力調(diào)度、車輛動(dòng)態(tài)、車輛調(diào)高度管理等，也在逐步采用高密度的LED顯示屏。</span> </p> <p> <span style="font-size:14px;">五、郵政、電信、商場(chǎng)購(gòu)物中心等服務(wù)領(lǐng)域的業(yè)務(wù)宣傳及信息顯示。</span> </p> <p> <span style="font-size:14px;">六、演出和**</span> </p> <p> <span style="font-size:14px;">大型顯示屏越來越普遍的用于公共的視頻直播，如在我國(guó)建國(guó)50周年大慶、世界各地的新千年慶典等重大節(jié)日中，大型顯示屏在播放實(shí)況和信息發(fā)布方面發(fā)揮了良好的作用。</span> 昆明雙色LED顯示屏批發(fā)真正的節(jié)能來源于：高亮度、高光效率向燈、高轉(zhuǎn)換效率電源。</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;" alt="昆明小間距LED顯示屏,LED顯示屏"

style="font-size:14px;">一、短路檢測(cè)法：</span> </p> <p> <span style="font-size:14px;">將萬(wàn)用表調(diào)到短路檢測(cè)擋（一般具有報(bào)警功能，如導(dǎo)通則發(fā)出鳴叫聲），檢測(cè)是否有短路的現(xiàn)象出現(xiàn)，發(fā)現(xiàn)短路后應(yīng)馬上解決，短路現(xiàn)象也是較常見的LED顯示屏模塊故障。有的通過觀察IC引腳和排針引腳就能發(fā)現(xiàn)。短路檢測(cè)應(yīng)在電路斷電的情況下操作，避免損壞萬(wàn)用表。這個(gè)方法是較常用到的方法，簡(jiǎn)單、高效。90%的故障都可以通過這個(gè)方法檢測(cè)判斷</span> </p> <p> <span style="font-size:14px;">二、電阻檢測(cè)法：</span> </p> <p> <span style="font-size:14px;">將萬(wàn)用表調(diào)到電阻檔，檢測(cè)一塊正常的電路板的某點(diǎn)的到地電阻值，再檢測(cè)另一塊相同的電路板的同一個(gè)點(diǎn)測(cè)試與正常的電阻值是否有不同，若不同則就確定了問題的范圍。</span> </p><p> <span style="font-size:14px;">什么是LED軟模組？</span> </p> <p> <span style="font-size:14px;">軟模組是相對(duì)于常規(guī)LED顯示屏模組而言的，常規(guī)模組采用硬板的PCB板和底殼面罩制作，沒有任何的柔軟度，硬板一塊。在遇到弧度，彎曲的地方要么不能用，要么需要進(jìn)行切角等特殊工藝來制作，但是成本會(huì)增加很多，而且工藝也不是很完美。</span> </p> <p> <span style="font-size:14px;">LED軟模組為了解決以上問題而被研發(fā)出來，LED軟模組又被稱為L(zhǎng)ED柔性屏，LED軟屏，因其模組柔軟度比較高，可折疊，可彎曲。</span> </p> <p> <span style="font-size:14px;">LED軟模組與常規(guī)的LED電子屏在顯示原理上是一樣的，不同的是采用柔性的PCB和底殼面罩，使得模組的柔軟度特別好，可以實(shí)現(xiàn)120度的折疊。</span> 室內(nèi)LED顯示屏的故障與保養(yǎng)。</p><div style="width:100%;text-align: center;"><img

style="font-size:14px;">LED電子顯示屏的維修檢測(cè)方法</span> </p> <p> <span style="font-size:14px;">1、電壓檢測(cè)法：</span> </p> <p> <span style="font-size:14px;">將萬(wàn)用表調(diào)到電壓檔，檢測(cè)懷疑有問題的電路的某個(gè)點(diǎn)的到地電壓，比較是不是與正常值相似，可以方便確定問題的范圍。</span> </p> <p> <span style="font-size:14px;">2、壓降檢測(cè)法：</span> </p> <p> <span style="font-size:14px;">將萬(wàn)用表調(diào)到二極管壓降檢測(cè)檔，因?yàn)樗械腎C都是由基本的眾多單元件組成，只是小型化了，所以在當(dāng)它的某引腳上有電流通過的時(shí)候，就會(huì)在引腳上存在電壓降。一般同一型號(hào)的IC相同引腳上的壓降相似，根據(jù)引腳上的壓降值比較好壞，須在電路斷電的情況下操作。</span> 目前LED透明屏有兩種制作方式，一種是正發(fā)光，一種是側(cè)發(fā)光。昆明雙色LED顯示屏批發(fā)</p><p style="text-indent:25px">LED電子顯示系統(tǒng)需要640x960小時(shí)的連續(xù)操作。昆明小間距LED顯示屏</p><p> <span style="font-size:14px;">LED電子顯示屏在監(jiān)控指揮中心的主要作用</span> </p> <p> <span style="font-size:14px;">1，實(shí)時(shí)監(jiān)控，24小時(shí)不間斷監(jiān)管</span> </p> <p> <span style="font-size:14px;">LED電子顯示系統(tǒng)需要640x960小時(shí)的連續(xù)操作，這需要非常高的質(zhì)量。即使在監(jiān)控顯示期間，也不能錯(cuò)過一秒，因?yàn)槿魏尉o急情況都可能隨時(shí)發(fā)生。</span> </p> <p> <span style="font-size:14px;">2，協(xié)助決策，收集高清顯示系統(tǒng)的信息</span> </p> <p> <span style="font-size:14px;">LED電子顯示器需要根據(jù)決策者的需要，以簡(jiǎn)潔直觀的形式收集和整理系統(tǒng)收集的各種信息，以及各種模型的分析和計(jì)算結(jié)果，或者顯示一些監(jiān)控圖像，也需要LED電子產(chǎn)品。顯示器具有高清顯示器。隨著技術(shù)的進(jìn)步，小間距LED電子顯示器使用范圍很廣，并且高清顯示器沒有壓力。</span> </p> <p> <span style="font-size:14px;">3.會(huì)議系統(tǒng)，視頻會(huì)議，會(huì)議，助理調(diào)度和指揮工作</span> </p> <p> <span style="font-size:14px;">LED電子顯示視頻會(huì)議系統(tǒng)旨在實(shí)現(xiàn)直觀，高效的調(diào)度和指揮工作，避免無(wú)圖像模式的電話會(huì)議的缺點(diǎn)，生動(dòng)地呈現(xiàn)各種決策和計(jì)劃。它還可以及時(shí)處理緊急情況和其他有效的危機(jī)。</span> </p> <p> <span style="font-size:14px;">LED電子顯示器用于各個(gè)領(lǐng)域。在信息技術(shù)時(shí)代，LED電子顯示屏將滲透到需要它的領(lǐng)域。為人們的生活帶來色彩，為人們的生活帶來安全。</span> 昆明小間距LED顯示屏</p><p
