江蘇印釩光電科技影響全彩室內(nèi)LED顯示屏品質(zhì)的因素-深圳室內(nèi)LED顯示屏1、失效率由于全彩室內(nèi)LED顯示屏由上萬甚至幾十萬組紅、綠、藍(lán)三種LED組成的像素點(diǎn)組成，任一顏色LED的失效均會影響顯示屏整體視覺效果。一般來說，按行業(yè)經(jīng)驗(yàn)，在led顯示屏開始裝配至老化72小時出貨前的失效率應(yīng)不高于萬分之三（指LED器件本身原因引起的失效）。2、抗靜電能力LED是半導(dǎo)體器件，對靜電敏感，極易引致靜電失效，故抗靜電能力對顯示屏的壽命至關(guān)重要。一般來說，LED的人體靜電模式測試失效電壓不應(yīng)低于2000V。3、衰減特性紅、綠、藍(lán)LED均具有隨著工作時間的增加而亮度衰減的特性。LED芯片的優(yōu)劣、輔助物料的好壞及封裝工藝水平的高低決定了LED的衰減速度。一般來說，1000小時、20毫安常溫點(diǎn)亮試驗(yàn)后，紅色LED的衰減應(yīng)小于10%，藍(lán)、綠色LED的衰減應(yīng)小于15%。紅、綠、藍(lán)衰減的一致性對全彩LED顯示屏日后的白平衡影響很大，進(jìn)而影響顯示屏的顯示保真度。4、亮度LED亮度是顯示屏亮度的重要決定因素。LED亮度越高，使用電流的余量越大，對節(jié)省耗電、保持LED穩(wěn)定有好處。LED有不同的角度值，在芯片亮度已定的情況下，角度越小，LED則越亮，但顯示屏的視角則越小。</p><p> 棕）連接到控制卡的GND，將DB9的3腳（棕白）連接到控制卡的RS232-RX。如果你的PC沒有串口，可以到電腦城買條USB轉(zhuǎn)RS232串口的轉(zhuǎn)換線。第5步：再次檢查連線，是否正確，黑線連接的是-V和GND。紅線連接的是+V和VCC+5V。第6步：接通220V，正常情況下，電源燈亮，控制卡亮，屏幕有顯示。如果不正常，請檢查連線。或者查看錯誤檢修。第7步：打開下載的軟件，設(shè)定屏幕的參數(shù)，發(fā)送字幕。具體參照軟件使用說明。7.外框制作：外框分類：支架，簡易框，不銹鋼邊框支架制作：根據(jù)不同的應(yīng)用場合，外框要求不一樣，我們先講述內(nèi)嵌安裝的時候，不需要外框，但是需要一個安裝支架。安裝支架一般用鋁型材，比較輕便，切割加工容易。我們也可以用多能角鐵（就是有很多孔的直角形的鐵條）。我們可以看到單元板背面有安裝用的銅柱，是用來把單元板固定在支架，支架應(yīng)該長一點(diǎn)，預(yù)留燈箱的安裝孔。把單元板，控制卡，電源都固定在支架，數(shù)據(jù)線和220V電源線要綁在支架上，要綁好，打個結(jié)，不要扯幾下就掉。這樣一個較簡單的屏幕就組裝好了?？梢阅萌グ惭b在其他設(shè)備上面，如燈箱。_簡易框制作流程：我們看到買回來的單元板，會發(fā)現(xiàn)亮度不一，或者應(yīng)用的場合可能有水花。鼓樓區(qū)異形顯示屏價格哪家好？江蘇印釩光電科技供應(yīng)！</p><div

制作排線，需要一個工具，就是特殊的鉗子（圖片），可以大的提高工作效率和良品率。制作排線的材料有：排線，排線頭，排線帽。這里要注意一下，如果你制作16PIN（16線）的排線，需要購買16PIN的線和相應(yīng)大小的排線頭和帽。制作步驟，把線頭用剪刀剪平，然后放頭排線頭，（注意線和頭的平衡），然后放進(jìn)壓線鉗的**，用力壓緊，然后把線繞過來，安裝排線帽。排線帽很重要，可以有效保護(hù)排線，讓排線更加結(jié)實(shí)，不要省。_電源線制作：電源分為220V電源線和5V電源線。220V電源線用于連接開關(guān)電源到市電，較好采用3腳插頭，可以在五金店買到。這里著重講述5V直流電的電源線，由于5V的電流比較大，較好采用銅芯直徑在1mm以上的紅黑對線（務(wù)必要紅黑）。有條件的話，較好將線的兩頭裝上金屬件。_RS232線制作：RS232線，用于連接電腦和控制卡，更新屏幕數(shù)據(jù)。這里需要用到DB9頭和網(wǎng)線（可以在電腦城買到）。仔細(xì)觀察DB9頭，上面有數(shù)字的，將5連接棕，將3連接棕白。將網(wǎng)線夾緊，裝好在DB9頭。（這里很重要，一定要夾緊，自己用力拉幾下，看看是否一拉就斷）。然后用萬用表測量一下兩頭，是否導(dǎo)通。這里需要指出。DB9的頭分**和母頭的。計算機(jī)后面的屬于母座，所以要買個公插對應(yīng)。江寧區(qū)室內(nèi)顯示屏價格哪家好？江蘇印釩光電科技供應(yīng)！南京戶外顯示屏價格</p><p
