A Flexible Multi-Functional Touch Panel for Multi-Dimensional Sensing in Interactive Displays

Touch screen panels (TSPs) have become an integral part of modern-day lifestyle.

To enhance user experience, attributes such as form-factor flexibility, multi-dimensional sensing, low power consumption and low cost have become highly desirable.

This Element addresses the design of multi-functional TSPs with integrated concurrent capture of ubiquitous capacitive touch signals and force information.

It compares and contrasts interactive technologies and presents design considerations for multi-dimensional touch screens with high detection sensitivity, accuracy and resolution.
