We have newly developed the mutual‐capacitive touch screen using double layered metal mesh electrodes with separated floating electrodes in borders between X‐ and Y‐directional electrodes. We have defined the effect of the floating electrode with an electric field simulation and improved the sensitivity and the response time of the touch screen by separating the floating electrode into several small patterns.
