</p> <p> <br /> </p> <p> <br /> </p> <p> 不同LED顯示屏模組對比 </p> <p> 左邊的LED顯示屏模組采用傳統(tǒng)的白燈，右邊的模組采用格特隆GES**模組，圖中為非點亮效果，可以想像當(dāng)LED顯示屏顯示內(nèi)容有明暗對比時，右邊的模組要遠好于左邊的。室內(nèi)LED顯示屏的LED表面形式有單燈、亞表貼、三拼一表貼和三合一表貼等幾種，外觀也不相同。重慶高速LED顯示屏尺寸</p><div style="width:100%;text-align:

灰度非線性變換，就是說在系統(tǒng)在把灰度數(shù)據(jù)傳送給LED顯示屏屏幕之前，首先對灰度數(shù)據(jù)進行相應(yīng)調(diào)整，調(diào)整的依據(jù)是經(jīng)驗性數(shù)據(jù)或是算術(shù)上的非線性關(guān)系。與以前顯示器所依照的非線性并不相同，LED顯示屏本身是線性器件，如果讓顯示屏顯示信息的效果與原始數(shù)據(jù)和灰度級別相符，LED系統(tǒng)就需要對灰度數(shù)據(jù)進行非線性變換。目前，我國市場上的LED控制系統(tǒng)中所說的4096或16384級灰度，都是進行非線性變換處理之后的結(jié)果。所謂亮度鑒別，是指圖像依靠人眼能夠分辨的從**黑到**白之間的亮度等級。人的眼睛對于亮度的鑒別是有限的，很可能相鄰的亮度等級在我們用眼睛看來沒有什么區(qū)別，但是對LED顯示屏來講,人眼的識別度與顯示屏質(zhì)量成正比。由于人眼對亮度識別程度越高，說明顯示屏的色彩空間越大，對色彩顯示進行豐富的空間也提高，所以人眼對屏幕亮度識別等級越高，說明LED顯示屏越好。重慶高速LED顯示屏尺寸在實際操作中，LED顯示屏體的尺寸越大，維護過程越復(fù)雜，維護成本自然會相應(yīng)增加。</p><div

七、保持電源穩(wěn)定 </p> <p> 保持供電電源穩(wěn)定必要時在配電箱內(nèi)加裝浪涌開關(guān)，并做好接地保護避免雷擊，在強雷電天氣及其他惡劣的自然條件下不要使用LED顯示屏。 </p> <p> 八、嚴(yán)禁屏體接觸水、金屬粉塵等易導(dǎo)電的物質(zhì) </p> <p> LED顯示屏盡量放置在低灰塵的環(huán)境中，否則會對顯示效果造成影響，同時會對電路造成損害。如果因為各種原因接觸到水，請立即斷電并聯(lián)系維修人員，直至LED顯示屏單元板干燥后方可使用。 </p> <p> <br /> </p><p> 九、控制屏體顯示 </p> <p> 建議不要使LED顯示屏長時間處于全白色、全紅色、全綠色、全藍色等全亮畫面，因為這樣會影響顯 </p> <p> 示屏使用壽命。請勿隨意拆卸、拼接屏體。 </p> <p> 十、控制使用時間 </p> <p> 建議LED顯示屏大屏幕每天至少休息2小時；一般每星期至少開啟LED顯示屏兩次以上（特別是梅雨季節(jié)時需要每天開啟一次），且點亮?xí)r間需要2小時以上。 </p> <p> 十一、單元板的貯存 </p> <p> 在LED顯示屏單元板使用前請不要拆開包裝，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> 請務(wù)必在倉庫中放置一個溫度、濕度計，隨時監(jiān)測溫度濕度。租賃LED顯示屏出租使用過程中，應(yīng)避免屏體淋到雨水或沾水，如不甚沾水，應(yīng)及時將水擦干并用吹風(fēng)機吹干。</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height:

LED顯示屏在我們?nèi)粘Ｉ钪袘?yīng)用的越來越普遍，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便利。在日常使用LED顯示屏?xí)r，我們要注意以下事項： </p> <p> 1）打開顯示屏?xí)r，要先開機，再開顯示屏；關(guān)閉顯示屏?xí)r，要先關(guān)顯示屏，再關(guān)機。開關(guān)顯示屏的時間間隔要在5分鐘以上。 </p> <p> 2）盡量在啟動計算機系統(tǒng)控制之后，再對屏幕進行通電。 </p> <p> 3）系統(tǒng)在白屏?xí)r，遭受的沖擊電流壓力比較大，這個時候盡量讓顯示屏在關(guān)閉狀態(tài)。 </p> <p> 4）計算機在失控時，遭受的沖擊電流壓力也很大，這種情況也不宜打開顯示屏。一旦出現(xiàn)計算機失控，要立即進行檢查，確定計算機是否通電、電源是否打開、計算機程序是否正常運行等。 </p> <p> 5）當(dāng)顯示屏處于高溫狀態(tài)，或是散熱條件不好，盡量不要打開顯示屏。 </p> <p> 6）在LED屏幕中間出現(xiàn)一道亮線或亮點時，要在***時間關(guān)閉顯示屏，縮短開屏?xí)r間。 </p> <p> 7）如果顯示屏開關(guān)經(jīng)常自動關(guān)閉，就要對顯示屏進行***檢查，或是更換控制開關(guān)。 </p> <p> 8）對顯示屏的懸掛進行檢查：掛屏是否牢固、屏幕是否完好、環(huán)境是否發(fā)生變化。拼接LED顯示屏顯示技術(shù)在比較大限度滿足客戶需求時始終無法避免物理邊框的影響。沈陽電子LED顯示屏租賃</p><p
