觸摸屏的工作原理及典型應(yīng)用

摘 要：由于設(shè)計采用平板液晶顯示器的觸摸屏(LCD)不斷增多，觸摸屏應(yīng)用已經(jīng)發(fā)展成為顯示器市場的一支生力軍。觸摸屏技術(shù)使界面能夠訪問計算機(jī)的數(shù)據(jù)庫，而不依賴于傳統(tǒng)的鍵盤-鼠標(biāo)界面。如果在應(yīng)用中計算機(jī)被編程為允許用戶通過菜單系統(tǒng)逐步查找信息，例如租車公司的指示或使用ATM，那么使用觸摸屏具有很強的優(yōu)勢。概要介紹碰到把握，而且操作原則的結(jié)構(gòu), 和輪流組粗刻邊的觸覺-褐色的把握控制薄片 ADS7843 為例,觸覺支撐應(yīng)用的典型樣板的電路和操作的介紹。因為在地方 12 A/Ds 里的 ADS7843, 接觸理論上支撐的輸入坐著作標(biāo)記不準(zhǔn)確性為有效長寬度 1/4096.

The work principle and typical model applications that touch hold
Abstact: Because the touch of the design adoption  flat panel liquid crystal display hold( LCD) to increase continuously, touching to hold the application to have already develop to become the display market of a livings the dint soldier.The synopsis introduction the structure that touch hold and work principle, and to take the touch of the company of Burr- Brown hold control the chip ADS7843 as an example, introduction touch hold the applied typical model electric circuit and operations.Because ADS7843 inside place 12 A/ Ds, the importation that touch to hold theoretically sit marking do not accuracy for valid long breadth of 1/4096
