Abstract
A touch sensing device may include: a pre-processing unit configured to reduce common signal noise and frequency components higher than a preset cut-off frequency from a pair of signals outputted from a touch panel, in response to a driving signal; and an attenuation unit configured to attenuate a frequency of a preset frequency region in an output signal of the pre-processing unit, and output a sensing signal.
