Patent abstract
A semiconductor device for use in a touch panel is capable of uniquely identifying the touched coordinates over the touch panel. When a multi-touch state is detected over the touch panel by a self-capacitance method, the semiconductor device isolates the multiple touch electrodes found to be in the touch state and has these electrodes identified by a mutual capacitance method.
