CAPACITIVE TOUCH PANEL HAVING A NON-PLANAR TOUCH SURFACE |
摘要 |
An improved capacitive touch panel includes a trimplate defining a non-planar touch surface, a planar array of capacitive sensing elements mounted behind the trimplate, and a formable interface element of high relative static permittivity sandwiched between the sensing elements and the inboard face of the trimplate. The interface element is a compression molded silicone rubber element having a first major surface that is sculpted to match and uniformly contact the inboard face of the trimplate, and a second major surface that is planar and uniformly contacts the planar array of capacitive sensing elements. The interface element has a limited amount of compliance so that slight compression of the interface element between the trimplate and sensing elements eliminates any air gaps between the contacting surfaces.
