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.
