Abstract

The work employs the finite element method to model the finger touch on the flexible ultra-thin touch panel for analyzing the touch signal. The touch signal generates the ghost points when the fingers multi-touch on the flexible ultra-thin touch panel. The simulation of minimizing the top layer (over cover) thickness based on the model is conducted in order to eliminate the ghost points. The simulation results show the over cover thickness should be larger than 107 μm to eliminate the ghost points. Further, we propose the method to solve the ghost points and minimize the over cover thickness. The simulation results conducted in this proposed method show that the over cover thickness can be reduced further to 65 μm.
