Abstract
An acoustic wave touch panel is shown for use with a non-active stylus. The acoustic wave touch panel includes an acoustic wave touch position sensor with an elastomeric substrate 20 overlying the touch position sensor and further including a stiff substrate overlying the elastomeric substrate. When a non-active stylus contacts a surface of the stiff substrate exerting a Z-axis force thereon, the Z-axis force is transmitted through the stiff substrate to the elastomeric substrate. The elastomeric substrate deforms in response to the Z-axis force and transmits the force to the acoustic wave touch sensor, the deformation of the elastomeric substrate absorbing or damping acoustic wave energy like a finger touch on the acoustic wave touch sensor.
