Abstract:
1. A dual-mode touch sensing apparatus, comprising: a substrate; a first touch sensing electrode formed on the substrate, wherein the first touch sensing electrode is used to perform a first type of touch sensing technology for sensing a touch position; a second touch sensing electrode formed on the substrate, wherein the second touch sensing electrode is used to perform a second type of touch sensing technology for sensing a touch position; and a switch circuit coupled with the second touch sensing electrode; wherein the first type touch sensing technology is a capacitive touch sensing technology, and the second type touch sensing technology is an electromagnetic touch sensing technology; wherein the first touch sensing electrode is a projected capacitive touch sensing electrode and the second touch sensing electrode is an electromagnetic touch sensing antenna; wherein when both a sensing pen and a user's finger touch the dual-mode touch sensing apparatus, the switch is turned off to stop an operation of the second touch sensing electrode.
