LED顯示屏在我們?nèi)粘Ｉ钪袘?yīng)用的越來(lái)越普遍，良好的使用習(xí)慣，可以增加顯示屏的使用壽命，在保證LED顯示屏質(zhì)量的前提下，為我們良好的使用效果帶來(lái)便利。在日常使用LED顯示屏?xí)r，我們要注意以下事項(xiàng)： </p> <p> 1）打開(kāi)顯示屏?xí)r，要先開(kāi)機(jī)，再開(kāi)顯示屏；關(guān)閉顯示屏?xí)r，要先關(guān)顯示屏，再關(guān)機(jī)。開(kāi)關(guān)顯示屏的時(shí)間間隔要在5分鐘以上。 </p> <p> 2）盡量在啟動(dòng)計(jì)算機(jī)系統(tǒng)控制之后，再對(duì)屏幕進(jìn)行通電。 </p> <p> 3）系統(tǒng)在白屏?xí)r，遭受的沖擊電流壓力比較大，這個(gè)時(shí)候盡量讓顯示屏在關(guān)閉狀態(tài)。 </p> <p> 4）計(jì)算機(jī)在失控時(shí)，遭受的沖擊電流壓力也很大，這種情況也不宜打開(kāi)顯示屏。一旦出現(xiàn)計(jì)算機(jī)失控，要立即進(jìn)行檢查，確定計(jì)算機(jī)是否通電、電源是否打開(kāi)、計(jì)算機(jī)程序是否正常運(yùn)行等。 </p> <p> 5）當(dāng)顯示屏處于高溫狀態(tài)，或是散熱條件不好，盡量不要打開(kāi)顯示屏。 </p> <p> 6）在LED屏幕中間出現(xiàn)一道亮線或亮點(diǎn)時(shí)，要在***時(shí)間關(guān)閉顯示屏，縮短開(kāi)屏?xí)r間。 </p> <p> 7）如果顯示屏開(kāi)關(guān)經(jīng)常自動(dòng)關(guān)閉，就要對(duì)顯示屏進(jìn)行***檢查，或是更換控制開(kāi)關(guān)。 </p> <p> 8）對(duì)顯示屏的懸掛進(jìn)行檢查：掛屏是否牢固、屏幕是否完好、環(huán)境是否發(fā)生變化。長(zhǎng)沙透明LED顯示屏多少錢一般簡(jiǎn)單的串聯(lián)連結(jié)方式中的LED1-n、首尾相連，led顯示屏工作時(shí)流過(guò)的電流相等。</p><div style="width:100%;text-align: center;"><img

造成顯示屏像素失控的原因很多，其中**主要的原因就是“LED失效”。 </p> <p> LED顯示屏失效的主因又可分為兩個(gè)方面：一是LED顯示屏自身品質(zhì)不佳;二是使用方法不當(dāng)。通過(guò)分析我們歸納出LED顯示屏失效模式和上述兩個(gè)主因之間的對(duì)應(yīng)關(guān)系。 </p> <p> 上述我們談到很多LED顯示屏的失效通常在LED的常規(guī)檢驗(yàn)測(cè)試中是無(wú)法發(fā)現(xiàn)的。除了在受到靜電放電、大電流(造成結(jié)溫過(guò)高)、外部強(qiáng)力等不當(dāng)使用外，很多LED顯示屏失效是在高溫、低溫、溫度快速變化或其他惡劣條件下，由于LED芯片、環(huán)氧樹(shù)脂、支架、內(nèi)引線、固晶膠、PPA杯體等材料熱膨脹系數(shù)的差異，引發(fā)其內(nèi)部應(yīng)力的不同而產(chǎn)生的，因此，LED顯示屏的質(zhì)量檢測(cè)是一項(xiàng)十分復(fù)雜的工作。 </p><p> 九、控制屏體顯示 </p> <p> 建議不要使LED顯示屏長(zhǎng)時(shí)間處于全白色、全紅色、全綠色、全藍(lán)色等全亮畫(huà)面，因?yàn)檫@樣會(huì)影響顯 </p> <p> 示屏使用壽命。請(qǐng)勿隨意拆卸、拼接屏體。 </p> <p> 十、控制使用時(shí)間 </p> <p> 建議LED顯示屏大屏幕每天至少休息2小時(shí)；一般每星期至少開(kāi)啟LED顯示屏兩次以上（特別是梅雨季節(jié)時(shí)需要每天開(kāi)啟一次），且點(diǎn)亮?xí)r間需要2小時(shí)以上。 </p> <p> 十一、單元板的貯存 </p> <p> 在LED顯示屏單元板使用前請(qǐng)不要拆開(kāi)包裝，并且放置于干燥的地方確保單元板存放在溫度不高于30℃,濕度不高于60%的環(huán)境中。 </p> <p> 十二、 </p> <p> 請(qǐng)務(wù)必在倉(cāng)庫(kù)中放置一個(gè)溫度、濕度計(jì)，隨時(shí)監(jiān)測(cè)溫度濕度。
