style="font-size:14px;">大屏幕模塊上的驅(qū)動(dòng)電路板驅(qū)動(dòng)IC的排布亦會(huì)影響到LED的亮度。由于驅(qū)動(dòng)IC輸出電流在PCB板上傳輸距離過遠(yuǎn)，會(huì)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(huì)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(gè)原因。故要保證大屏幕亮度的一致性，就要設(shè)計(jì)好驅(qū)動(dòng)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，昆明室內(nèi)P4全彩大屏，過爐時(shí)要有足夠的工藝技術(shù)保證LED垂直于PCB板，昆明室內(nèi)P4全彩大屏。任何的偏差都會(huì)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> LED顯示屏面積越大，昆明室內(nèi)P4全彩大屏，使用的電量越大，發(fā)熱越明顯。昆明室內(nèi)P4全彩大屏</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;" alt="昆明室內(nèi)P4全彩大屏,全彩" src="https://tyunfile.71360.com/WaterMark/UploadFile/qichuang2020/637384652347566938/4128590.png"></div><p> <span style="font-size:14px;">選用酒店全彩LED顯示屏?xí)r，主要從以下幾個(gè)方面考慮。</span> </p> <p> <span style="font-size:14px;">1、實(shí)像素與虛擬像素。與戶外全彩LED顯示屏一樣，室內(nèi)全彩屏的像素?cái)?shù)也分為實(shí)像素和虛擬像素兩種。</span> </p> <p> <span style="font-size:14px;">2、管芯。良好的管芯能保證LED的質(zhì)量。</span> </p> <p> <span style="font-size:14px;">3、封裝形式。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。表貼封裝的優(yōu)點(diǎn)是視角大，發(fā)光一致性好，易于自動(dòng)焊接加工，是全彩LED屏的主流品，但現(xiàn)在價(jià)格相對較高;單燈視角相對稍小，亮度稍高，價(jià)格較低。亞表貼其實(shí)也是單燈的一種。單燈和亞表貼都較為便宜，是一種過渡性產(chǎn)品。</span> </p> <p> <span style="font-size:14px;">4、密度。由于室內(nèi)全彩LED芯片發(fā)熱量較大，控制電路密度較高，故現(xiàn)在商品化的全彩屏的點(diǎn)密度還不能做得很高。</span> </p> <p> <span style="font-size:14px;">5、驅(qū)動(dòng)方式。室內(nèi)全彩LED顯示屏的驅(qū)動(dòng)方式都是恒流驅(qū)動(dòng)，采用動(dòng)態(tài)掃描方式(主要有1/4、1/8等掃描方式)。在管芯相同的情況下，1/4掃描用的電路要多些，亮度也要高些。</span> 昆明P5室內(nèi)全彩電子屏廠家控制系統(tǒng)是全彩LED顯示屏重要的一部分。</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;" alt="昆明室內(nèi)P4全彩大屏,全彩"

style="font-size:14px;">1、箱體要擺放的地點(diǎn)需打掃干凈后，用珍珠棉鋪設(shè)。</span> </p> <p> <span style="font-size:14px;">2、LED顯示屏嚴(yán)禁雜亂堆放模組或堆疊10張以上。模組堆疊時(shí)，燈面相對擺放并使用珍珠棉進(jìn)行隔離。</span> </p> <p> <span style="font-size:14px;">3、LED顯示屏箱體的擺放建議燈面朝上平放，如數(shù)量太多需要立放時(shí)要特別注意保護(hù)，震動(dòng)較大的地點(diǎn)禁止立放。</span> </p> <p> <span style="font-size:14px;">4、顯示屏箱體要輕拿輕放，落地時(shí)后側(cè)先著地再燈面著地，謹(jǐn)防磕傷。</span> </p> <p> <span style="font-size:14px;">5、搬運(yùn)箱體時(shí)應(yīng)抬起，不得在地面上推或者拖走，以免地面凹凸不平造成底部模組損傷。箱體在吊起過程中應(yīng)保持平衡，不得在空中左右擺動(dòng)，旋轉(zhuǎn)。安裝箱體或模組時(shí)需輕拿輕放，嚴(yán)禁拋擲。</span> </p> <p> <span style="font-size:14px;">6、LED顯示屏產(chǎn)品如需要進(jìn)行調(diào)節(jié)，則使用軟膠錘擊打箱體金屬部分，嚴(yán)禁擊打模組。嚴(yán)禁模組間出現(xiàn)擠壓、碰撞等行為?？p隙、定位異常等情況時(shí)，嚴(yán)禁使用鐵錘等硬物敲打箱體和模組，可將箱體拿起排除異物后再次嘗試。</span> </p><p style="text-indent:25px"><span style="font-size:14px;">考慮到用于戶內(nèi)外的全彩LED大屏幕顯示媒體對顯示設(shè)備的顏色、亮度、視頻效果、可靠性、壽命等性能要求比較苛刻。它要求室內(nèi)LED顯示屏顯示系統(tǒng)能夠顯示出接近于自然色彩的真彩畫面，并且具有較高的顯示亮度，無論是在白天還是在晚上，晴天還是陰天，都能夠讓觀眾清楚地看到其內(nèi)容，并且能夠根據(jù)外部自然光強(qiáng)度的變化自動(dòng)地對其顯示正在播放的視頻節(jié)目，具有較高的可靠性和性能價(jià)格比，易于維護(hù)。綜合上述諸多的因素，工程技術(shù)人員通過對磁翻版、真空像素管、電視墻LED顯示屏的比較，發(fā)現(xiàn)室內(nèi)LED顯示屏作為顯示像素可以很好的滿足上述要求，是一種很好的戶內(nèi)外顯示屏媒體。</span>小間距室內(nèi)全彩LED顯示屏是信息可視化的重要載體。</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;" alt="昆明室內(nèi)P4全彩大屏,全彩"

style="font-size:14px;">一、亮度的測試和產(chǎn)品使用說明</span> </p> <p> <span style="font-size:14px;">(1)檢測和使用LED時(shí)，一定要給每個(gè)LED提供相同電流即恒流檢測，才能保證檢測亮度一致，電流不要超過20mA，使用15-19mA的電流。</span> </p> <p> <span style="font-size:14px;">(2)使用分光分色的產(chǎn)品時(shí)，請按BIN號(hào)的先后順序歸類使用，不能把不同BIN號(hào)LED混合使用在同一產(chǎn)品中，以免產(chǎn)生顏色，亮度，電壓的差異。如果要混BIN號(hào)使用，相鄰BIN號(hào)可放一起，但盡量避免。</span> </p> <p> <span style="font-size:14px;">二、使用電流</span> </p> <p> <span style="font-size:14px;">(1)室內(nèi)LED顯示屏具有隨著電壓稍加而電流迅速增加之特性。</span> </p> <p> <span style="font-size:14px;">(2)過高的電流會(huì)引起LED燈的燒毀或亮度的衰減。</span> </p> <p> <span style="font-size:14px;">(3)在使用時(shí)應(yīng)加一個(gè)電阻與LED燈串聯(lián)，起到限流作用。</span> </p> <p> <span style="font-size:14px;">(4)室內(nèi)LED顯示屏應(yīng)在相同的電流條件下工作，一般建議通LED的電流為15-19mA。</span> </p> <p> <span style="font-size:14px;">三、防靜電注意事項(xiàng)</span> </p> <p> <span style="font-size:14px;">(1)所有接觸室內(nèi)LED顯示屏的設(shè)備和儀器一定要接地良好，特別焊接的烙鐵和錫爐一定要接地良好。</span> </p> <p> <span style="font-size:14px;">(2)操作人員一定要佩帶接地的防靜電手腕，穿防靜電鞋及防靜電衣服。</span> </p> <p> <span style="font-size:14px;">(3)防靜電手腕一定要每天進(jìn)行測試，不合格的一定要更換。</span> </p> <p> <span style="font-size:14px;">(4)若LED顯示屏有被靜電損害，會(huì)顯示一些不良特性：漏電電流增加，靜態(tài)順向電壓降低或上升，在低電流測試下不亮或發(fā)光不正常。</span> </p> <p> <br /> </p> <p> <br /> 全彩LED顯示屏箱體內(nèi)空間密封，空氣不對流 (建議加裝百葉防雨窗,下方進(jìn)氣上方排氣)。昆明室內(nèi)P4全彩大屏</p><p style="text-indent:25px">LED電子顯示屏的維修檢測方法有哪些？昆明室內(nèi)P4全彩大屏</p><p
