第一步：吸塵。先吸除掃除LED大屏面罩表面的污垢和灰塵。 </p> <p> 第二步：濕洗，沈陽室內(nèi)大屏供應，沈陽室內(nèi)大屏供應。使用水噴及蒸汽加濕噴射LED大屏面罩，用吸塵器上的軟毛刷對燈管面罩進行刷洗，將污垢清刷干凈。 </p> <p> 第三步：烘干。利用吸塵器吸干濕洗后留下的水珠和水痕，確保LED大屏面罩整潔無灰塵。戶外LED大屏需要經(jīng)常保養(yǎng)才能發(fā)揮比較好的顯示效果。 </p> <p> <br /> 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。沈陽室內(nèi)大屏供應</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;" alt="沈陽室內(nèi)大屏供應,大屏" src="https://tyunfile.71360.com/WaterMark/UploadFile/scchkj123/637432972968042921/4297435.png"></div><p> 6.電路設計部分 </p> <p> 電路板的設計及用料對LED大屏的穩(wěn)定性和顯示效果有至關重要的作用。主要有以下幾個方面的要求： </p> <p> 1、用料方面的要求：PCB板厚，一般使用1.6mm的厚度;材質(zhì)：FR-4玻璃纖維板，一些廠家為了降低成本可能會使用FR-2的紙基板;銅箔厚度：銅箔的厚度對PCB板的散熱及線路的穩(wěn)定性有著不可忽視的作用，正常的銅箔厚度是35um(1Oz)，而有些廠家會使用18um(0.5Oz)的銅箔厚度來以次充好;那么作為消費者怎么來辨別呢?可以拿一塊空的PCB通過重量來區(qū)別，正常情況下，越重越好。 </p> <p> 2、設計方面的幾個關鍵點：接插件，接插件是指模組與模組之間的連接件，現(xiàn)在市場上用得比較多的主要有兩種，一種是牛角，一種是排針。牛角的優(yōu)點是通過兩個卡位能卡住排線，不容易出現(xiàn)因接插件問題而引起的故障;有關電解電容和鉭電容的選擇，對于要求長壽命的場合，鉭電容無疑是比較好的選擇，對于要求低價的場合，電解電容是比較好的選擇。成都室內(nèi)大屏代理商LED大屏憑借出色的亮度和色彩表現(xiàn)，以及無拼縫的畫面完整性，愈來愈受到市場的青睞。</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;" alt="沈陽室內(nèi)大屏供應,大屏" src="https://tyunfile.71360.com/WaterMark/UploadFile/scchkj123/637432974897832215/8611606.png"></div><p> 三、局部色塊缺失 </p> <p> 對LED大屏了解的朋友們肯定見過這種問題，就是LED大屏正常播放時出現(xiàn)一個小方塊的異色塊，方方正正，這種問題一般是背后控制該色塊的顏色IC燒掉了，處理的辦法就是換一顆新的IC即可。 </p> <p> 四、局部黑屏和大面積黑屏 </p> <p> 通常我們講黑屏是指LED大屏正常播放時，一塊或多塊LED模組呈現(xiàn)整區(qū)域的不亮現(xiàn)象，少數(shù)幾塊LED模組區(qū)域不亮我們稱之為局部黑屏，更多區(qū)域的我們稱之為大面積黑屏。一般排查一下LED電源指示燈是否正常工作，如果LED電源指示燈不亮多為電源損壞，換一個新的對應功率的電源即可，也應該排查一下黑屏對應的LED模組電源線是否出現(xiàn)松動，很多時候重新擰一下線頭也能解決黑屏問題。 </p> <p> 五、局部亂碼 </p> <p> 局部亂碼問題比較復雜，系指LED大屏播放時局部區(qū)域出現(xiàn)雜亂的無規(guī)則的可能隨機閃爍的色塊現(xiàn)象。出現(xiàn)這種問題，我們一般首先排查信號線連接問題，可以檢查一下排線是否燒掉，網(wǎng)線是否松動，等等。維修實踐中我們發(fā)現(xiàn)鋁鎂絲材質(zhì)的排線容易燒壞，而純銅排線壽命較長。如果檢查整個信號連接沒有問題，那么交換一下出問題的LED模組與鄰近正常播放的模組，基本就可以判斷是否有可能就是播放異常區(qū)域?qū)腖ED模組損壞了，損壞原因多為IC問題，維修處理起來也會比較復雜。 </p> <p> <br /> </p><p> 這幾年，LED大屏在室外廣告領域占據(jù)著重要地位。每個項目的要求各不相同，比如對價格/像素/分辨率/播放內(nèi)容/使用壽命以及前置或后置維修等選擇的不同，會有不同的權衡。 </p> <p> 并且還要考慮安裝位置的承重能力，安裝環(huán)境周圍的亮度，觀眾的觀看距離和觀看角度，所以如何來采購LED大屏呢? </p> <p> LED大屏顯示內(nèi)容的需要 </p> <p> 長寬比例，圖文屏根據(jù)現(xiàn)實的內(nèi)容來定，視頻屏，一般為4:3或者是就近4:3，理想比例是16:9。 </p> <p> LED大屏可視距離、視角的確認 </p> <p> 為了保證在光線強烈的情況下遠距離可視，必須選用超高亮度發(fā)光二極管。 </p> <p> LED大屏外觀設計 </p> <p> 目前已經(jīng)能做到根據(jù)建筑物的設計及形狀量身定制LED顯示屏，比如2008年的奧運會和春節(jié)聯(lián)歡晚會，便是將LED顯示技術應用到了***，以達到極其完美的視覺效果。隨著LED大屏技術的不斷升級，LED大屏在很多大型慶典活動、晚會、等各類活動中擔任著越來越重要的角色。</p><div style="width:100%;text-align:

3.戶外LED大屏電路芯片選擇 </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致顯示屏啟動 </p> <p> 4.戶外LED大屏安裝通風設備降溫，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、短路五大防功能戶外LED大屏不僅能滿足商業(yè)用的高視覺品質(zhì)的要求，同時也能充分考慮消費者的個性化需求。成都室內(nèi)大屏代理商</p><p
