DVI接口端子定義


DVI全稱為Digital Visual Interface,即數字視頻接口。其外觀如附圖所示的接插件。在液晶顯示器上使用DVI接口,比用傳統模擬VGA接口的優勢明顯。液晶顯示器本身只能處理數字信號,如果使用VGA接口,就必須把輸入的模擬信號轉換成數字信號,而DVI傳輸的是數字信號,可直接傳送到顯示設備上,從而顯著提高顯示效果。


目前它已經成為主流顯卡的標配接口,而大多數中高檔液晶顯示器也配備了DVI數字接口。 DVI接口分DVI-I、DVI-D、DVI-A三種。DVI-I可傳輸數字信號和模擬信號;DVI-D只能傳輸數字信號;而DVI-A只能傳輸模擬信號,與VGA接口相似,目前基本被淘汰。


DVI-I接口端子定義見附圖。
