SURFACE CAPACITIVE TOUCH PANEL WITH MULTI-POINT TOUCH STRUCTURE AND MULTI-POINT TOUCH METHOD THEREOF

摘要

The invention relates to a surface capacitive touch panel capable of simultaneously determining different touch points, and a method thereof. The touch panel includes a transparent substrate, a transparent electroconductive layer and an electrode pattern layer. The electrode pattern layer includes at least one first X-side electrode, at least one second X-side electrode, at least one first Y-side electrode and at least one second Y-side electrode, which surround a rectangular area and are formed on a surface periphery of the transparent electroconductive layer. The impedances of the X-side and Y-side electrodes are configured in an ascending manner or a descending manner with a common difference or a common ratio toward the same side, so that impedances of two touch points on the same horizontal or vertical line of the touch panel have a gradient phenomenon to prevent currents from offsetting each other when the two touch points are moved.
