style="font-size:14px;">1、虛焊控制</span> </p> <p> <span style="font-size:14px;">LED大屏幕在出現(xiàn)LED不亮?xí)r，往往有超過50%概率為各種類型的虛焊引起的，如LED管腳虛焊、IC管腳虛焊、排針排母虛焊等。這些問題的改善需要嚴(yán)格地改善工藝并加強質(zhì)量檢驗來解決。出廠前的振動測試也不失為一種好的檢驗方法。</span> </p> <p> <span style="font-size:14px;">2、過波峰焊溫度及時間</span> </p> <p> <span style="font-size:14px;">須嚴(yán)格控制好波鋒焊的溫度及過爐時間，建議為：預(yù)熱溫度100℃±5℃，不超過120℃，且預(yù)熱溫度上升要求平穩(wěn)，焊接溫度為245℃±5℃，焊接時間建議不超過3秒，過爐后切忌振動或沖擊LED，直到恢復(fù)常溫狀態(tài)。波峰焊機的溫度參數(shù)要定期檢測，這是由LED的特性決定的，過熱或波動的溫度會直接損壞LED或造成LED質(zhì)量隱患，尤其對于小尺寸如3mm的圓形和橢圓形LED。</span> </p> <p> <span style="font-size:14px;">3、防靜電</span> </p> <p> <span style="font-size:14px;">LED大屏幕裝配工廠應(yīng)有良好的防靜電措施。**防靜電地、防靜電地板、防靜電烙鐵、防靜電臺墊、防靜電環(huán)、防靜電衣，昆明室內(nèi)全彩大屏幕廠家、濕度控制，昆明室內(nèi)全彩大屏幕廠家、設(shè)備接地(尤其切腳機)等都是基本要求，昆明室內(nèi)全彩大屏幕廠家，并且要用靜電儀定期檢測。</span>

style="font-size:14px;">1.檢查顯示器與顯卡的連線是否松動。接觸不良導(dǎo)致出現(xiàn)"雜波"、"雜點"狀的花屏是常見的現(xiàn)象。</span> </p> <p> <span style="font-size:14px;">2.檢查顯卡是否過度超頻。若顯卡過度超頻使用，一般會出現(xiàn)不規(guī)則、間斷的橫紋。這時，應(yīng)該適當(dāng)降低超頻幅度。注意，首先要降低顯存頻率。</span> </p> <p> <span style="font-size:14px;">3.檢查顯卡的質(zhì)量。若是更換顯卡后出現(xiàn)花屏的問題，且在使用一、二招未能奏效后，則應(yīng)檢查顯卡的抗電磁干擾和電磁屏蔽質(zhì)量是否過關(guān)。具體辦法是：將一些可能產(chǎn)生電磁干擾的部件盡量遠離顯卡安裝(如硬盤)，再看花屏是否消失。若確定是顯卡的電磁屏蔽功能不過關(guān)，則應(yīng)更換顯卡，或自制屏蔽罩。</span> </p> <p> <span style="font-size:14px;">4.檢查顯示器的分辨率或刷新率是否設(shè)置過高。液晶顯示器的分辨率一般低于CRT顯示器，若超過廠家推薦的分辨率，則有可能出現(xiàn)花屏的現(xiàn)象。</span> </p> <p> <span style="font-size:14px;">5.檢查是否安裝了不兼容的顯卡驅(qū)動程序。這種情況一般容易被忽視，因為顯卡驅(qū)動程序的更新速度越來越快(尤其是NVIDIA顯卡)，有些用戶總是迫不及待地安裝新版本的驅(qū)動。</span> </p> <p> <br /> 昆明P3室內(nèi)全彩屏幕價格LED顯示屏怎么做散熱處理？</p><div

style="font-size:14px;">1、驅(qū)動電路設(shè)計</span> </p> <p> <span style="font-size:14px;">大屏幕模塊上的驅(qū)動電路板驅(qū)動IC的排布亦會影響到LED的亮度。由于驅(qū)動IC輸出電流在PCB板上傳輸距離過遠，會使得傳輸路徑壓降過大，影響LED的正常工作電壓導(dǎo)致其亮度降低。我們常會發(fā)現(xiàn)大屏幕模塊四周的LED亮度比中間低一些，就是這個原因。故要保證大屏幕亮度的一致性，就要設(shè)計好驅(qū)動電路分布圖。</span> </p> <p> <span style="font-size:14px;">2、控制好燈的垂直度</span> </p> <p> <span style="font-size:14px;">對于直插式LED來說，過爐時要有足夠的工藝技術(shù)保證LED垂直于PCB板。任何的偏差都會影響已經(jīng)設(shè)置好的LED亮度一致性，出現(xiàn)亮度不一致的色塊。</span> </p><p> <span style="font-size:14px;">如何選購戶外LED顯示屏？</span> </p> <p> <span style="font-size:14px;">1、看戶外LED顯示屏的平整度</span> </p> <p> <span style="font-size:14px;">為了保證顯示圖像不會發(fā)生扭曲，戶外LED顯示屏的表面平整度就一定要保持在±1mm以內(nèi)。如果達不到這個要求，并且局部出現(xiàn)凹凸的現(xiàn)象就會導(dǎo)致戶外LED顯示屏在播放視頻時出現(xiàn)可視角度有死角的問題。因此，可以說平整度是判斷高質(zhì)量戶外LED顯示屏的一個主要因素。</span> </p> <p> <span style="font-size:14px;">2、看戶外LED顯示屏的亮度</span> </p> <p> <span style="font-size:14px;">一般情況下戶外LED顯示屏的亮度應(yīng)該達到1500cd/m2以上，才可以保證進行正常的顯示工作，不然就會因為亮度不夠而讓大家看不清播放的圖像內(nèi)容。所以要想買到顯示效果好的戶外LED顯示屏就要看其LED燈珠的質(zhì)量及其亮度參數(shù)。</span> </p> <p> <span style="font-size:14px;">3、看戶外LED顯示屏的白平衡</span> </p> <p> <span style="font-size:14px;">當(dāng)紅綠藍這三種原色比例是1：4.6：0.16的時候，LED屏幕才會顯示出**的白。因此，如果戶外LED顯示屏廠家所生產(chǎn)的LED顯示屏在三原色比例上略有偏差，就會導(dǎo)致白平衡出現(xiàn)偏差，從而導(dǎo)致戶外LED顯示屏的顯示質(zhì)量受到影響。所以，在采購時看LED顯示屏的白平衡也是很重要的。</span>
