1. A touch sensing device comprising:
- a touch screen panel including a touch sensor configured to generate a first electrical change corresponding to a touch; and
a touch controller configured to detect touch position data with respect to an area on the touch screen panel associated with the touch, based on the first electrical change of the touch sensor,the touch controller including,a first detection unit configured to detect the first electrical change in the touch sensor in a first mode as a plurality of pieces of candidate position data with respect to an area of at least two hoverings; and
a second detection unit for configured to detect a second electrical change in at least one area of the touch sensor corresponding to the plurality of pieces of candidate position data in a second mode that is different from the first mode, the second detection unit configured to select the touch position data with respect to the at least two hoverings based on the second electrical change.
