本文主要針對電容式觸控按鍵設計做討論,也實際利用目前市場提供的電容式觸控IC結合ITO Glass來模擬觸控設計。 現今觸控IC設計已非常成熟,本文將深入探討和如何克服電容式觸控IC的設計架構。

這論文將應用歐洲半導體廠,意法半導體公司所提供的電容式觸控IC結合一片1.8”OLED Panel Display來模擬按鍵式觸控,我們將一一探討這電容式觸控的原理,主要以軟板FPC為設計的條件跟玻璃式的ITO做結合。

The human interfacing technology had been with us for many years. Such technology had lived with us and widely implement in our daily live. We interface it from ATM machine, portable application such as mobile phone, notebook. This begins with simple mechanical key touch to Acustic-wave touch, resistive type touch, and now widely adopted capacitive touch technology. Recently the quick evolution of human interface technology change the behavior we control handheld devices such as mobile phone. The boom starting with Appel IPhone who chose capacity sensing technology in portable media players and it had replaced conventional mechanical keys. This concept of human interface will begin to evolve in our life. I would like to take this opportunity to explore the implementation of capacitive touch technology, using this application into ITO layer to practice the solution.
