Abstract
Provided are a touch sensing apparatus and a method of driving the same. The touch sensing apparatus includes a signal source configured to output a driving signal, a touch panel configured to be driven by the driving signal output by the signal source and output a current signal generated using the driving signal, a charge amplifier configured to convert the current signal output by the touch panel into a voltage signal, and a controller configured to control the charge amplifier to be periodically reset.
