Abstract
There are provided a touch sensing device and a touchscreen device, the touch sensing device including a plurality of driving electrodes extended in a first axial direction, a plurality of sensing electrodes extended in a second axial direction intersecting with the first axial direction, an integrating circuit unit generating a first analog signal by integrating a change in capacitance generated in a first sensing electrode among the plurality of sensing electrodes and generating a second analog signal from a change in capacitance generated in a second sensing electrode adjacent to the first sensing electrode, and a subtracting unit calculating a difference in levels between the first and second analog signals.
