Abstract
A mutual inductive capacitive touch screen is disclosed. The screen includes a plurality of drive lines, a plurality of sense lines and an electrode structure including a plurality of first electrodes and a plurality of second electrodes. The first electrodes are connected with the drive lines of the touch screen and the second electrodes are connected with the sense lines of the touch screen, or the first electrodes are connected with the sense lines of the touch screen and the second electrodes are connected with the drive lines of the touch screen. In addition, the electrode structure has an isotropic detection characteristic.
