► LVDS (Low Voltage Differential Signaling) interface
► LED driver circuit is built in this module to provide PWM Dimmer function.
VGG191201-A是一款17.0吋廣溫 TFT ，其規格非常適合應用於廣溫環境下需要TFT LCD顯示的產品，在影像資料傳輸上支援LVDS介面。在產品操作使用上其工作溫度是-20~80℃，儲存溫度是-40~85℃。
目前市面上常見的TFT LCD模組產品對於寬溫的定義範圍為-20~70℃，而針對工控、車載、室外產品的應用，其這樣的溫度範圍往往並不能符合該類產品應用的需求。因應客戶的需求，億力光電推出一系列超廣溫 TFT 液晶模組顯示器，其模組操作溫度可到達超廣溫-30℃ 至 +80℃，部分型號高溫更可到達85℃。
