Description:
This webinar demonstrates XFdtd's Electrostatic Solver for touchscreen design. This capability was developed for teams designing sensor and drive lines in touchscreens.
The demonstration introduces the following capabilities:
User interface for importing and manipulating geometry
Specification of driving and sensing lines
Results for capacitance matrices and field visualization
Positioning of human hands
Brochures
XFdtd® can compute the capacitance of complex sensor designs, allowing the designer to choose the best geometry for their needs without prototyping.

Application Examples
The capacitance matrices for a 3x4 touchscreen are analyzed in an unloaded and loaded case. Based on the changes in capacitance, the location of the 1 mm stylus is identified.
