style="font-size:14px;">LED電子顯示屏在生活中的應(yīng)用越來(lái)越廣，大屏幕顯示技術(shù)也在不斷提高。目前，液晶顯示以其優(yōu)異的顯示效果非常好，但大屏幕顯示中的拼接技術(shù)還沒(méi)有達(dá)到無(wú)縫水平，LED的小間距彌補(bǔ)了這一缺陷，并正在成功崛起。在大屏幕無(wú)縫拼接技術(shù)成熟期，LED電子顯示屏如雨后春筍般涌現(xiàn)，占領(lǐng)了大屏幕顯示市場(chǎng)。</span>

style="font-size:14px;">戶外LED廣告牌的使用現(xiàn)在比較的普及，一般安裝的位置都是一些車流量比較多的地方，在這里使用燈光首先考慮到的就是是否會(huì)對(duì)過(guò)往的車輛造成一定的困擾。有些燈光的安裝就十分不合理，在照射廣告牌的同時(shí)，燈光也照射到了路面及過(guò)往的車輛和行人，這個(gè)時(shí)候就有一定的危險(xiǎn)因素。因?yàn)樵谇胺饺绻怯斜容^亮的燈光會(huì)讓人們的眼睛暫時(shí)失去判斷或看不清楚前方的路況，這種狀態(tài)下很容易造成交通事故的發(fā)生。</span>

<p> <span style="font-size:14px;">2、屏上某一塊板子呈現(xiàn)正色、并排連續(xù)幾個(gè)燈顯現(xiàn)異常。(那就是板子問(wèn)題，替換異常顯現(xiàn)的板子即可，室內(nèi)屏貼墻裝置的普通是磁鐵吸的，用點(diǎn)力摳下板子改換即可）</span> </p> <p> <span style="font-size:14px;">3、屏幕有大片區(qū)域顯現(xiàn)異常，或是不斷在閃。(應(yīng)該是LED控制卡有問(wèn)題，檢查區(qū)域是哪張接納卡故障，改換控制卡就能夠處理)</span> </p> <p> <span style="font-size:14px;">4、電腦網(wǎng)線與LED屏幕網(wǎng)線銜接好的，軟件上提示“沒(méi)有找到大屏幕系統(tǒng)”，即便LED屏幕也能正常播放圖片、視頻功用，但軟件設(shè)置發(fā)送的數(shù)據(jù)全是失敗，(普通是發(fā)送卡呈現(xiàn)問(wèn)題，替換即可)</span>

style="font-size:14px;">正常情況下，LED電子顯示屏都是有一定的壽命的，使用一定時(shí)期之后燈泡的亮度會(huì)大幅下降，此時(shí)就是提醒燈泡該換了。因?yàn)榇藭r(shí)的燈泡是十分容易的，一旦出現(xiàn)這種情況燈泡的損失倒是小事兒，如果將高溫隔熱玻璃炸碎的話就太得不償失了。所以一定要記住對(duì)于燈泡進(jìn)行定期檢查并更換，避免事故的發(fā)生。</span> </p> <p> <span style="font-size:14px;">另外值得提醒的還有，LED電子顯示屏拼接單元鏡片的故障率是比較高的，各組鏡片中偏振片的損壞又較為常見(jiàn)，大部分是鍍層被燒傷，而偏振片上的鍍層灼傷又與機(jī)器散熱不好、機(jī)內(nèi)環(huán)境溫度高息息相關(guān)。因此定期對(duì)設(shè)備進(jìn)行各種保養(yǎng)是機(jī)器工作在較佳的環(huán)境下的關(guān)鍵因素。</span> LED顯示屏需定期檢查是否正常工作，線路有無(wú)損壞，如不工作要及時(shí)更換，線路有損壞要及時(shí)修補(bǔ)或者更換。昆明移動(dòng)LED顯示屏安裝</p><p style="text-indent:25px">購(gòu)買LED顯示屏需要注意什么？云南其創(chuàng)電子科技供應(yīng)。昆明移動(dòng)LED顯示屏安裝</p><p> <span style="font-size:14px;">解決LED顯示屏亮線的三個(gè)步驟</span> </p> <p> <span 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(guò)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(méi)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?？梢詼y(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(kāi)，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(shuō)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(shuō)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(méi)有接好，如果接好了，就很有可能是卡出問(wèn)題了。只要這兩個(gè)功能良好，控制卡就是好的，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。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(wèn)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> 昆明移動(dòng)LED顯示屏安裝</p><p
