觸控式螢幕















觸控螢幕圖解




触屏手机


触控萤幕（英语：Touchscreen），是可以接收觸頭（包括手指或者膠筆頭等）等輸入訊號的感應式液晶顯示、平板螢幕或电子墨水裝置。當接觸了螢幕上的圖形按鈕時，螢幕上的觸覺反饋系統可根據預先編程的程式驅動各種連結裝置，可用以取代機械式的按鈕面板，並藉由顯示畫面製造出生動的影音效果。
觸控螢幕的用途非常廣泛，從常見的提款機、PDA、到工業用的觸控電腦，因為觸控螢幕為親切且生動的人機介面。2007年以後，愈來愈多智能手机也採用了觸控式螢幕，典型的例子如iPhone。



種類


通常是在半反射式液晶面板上覆蓋一層壓力板，其對壓力有高敏感度，當物體施壓於其上時會有電流訊號產生以定出壓力源位置，並可動態追蹤。
現亦有In cell Touch觸控元件整合於顯示面板之內，使面板本身就具有觸控功能，不需另外進行與觸控面板的貼合與組裝即可達到觸控的效果與應用。
