1. A touch sensing apparatus, comprising:
a first substrate; a plurality of magnetic sensor patterns coupled to the first substrate, each of the magnetic sensor patterns to sense a change in a magnetic field caused by a touch input; and a plurality of conductive patterns corresponding to the magnetic sensor patterns, wherein the magnetic sensor patterns overlap respective ones of the conductive patterns to form corresponding sensing cells, each magnetic sensor pattern to sense magnetic field changes produced by a change in current in a corresponding conductive pattern to detect the touch input, and wherein each magnetic sensor pattern is to output: a first signal corresponding to the change in magnetic field caused by the touch input, the change in magnetic field produced by the change in current in at least one of the conductive patterns, and a second signal corresponding to a magnetic field generated by a stylus pen.
