Abstract
There are provided a touch sensing apparatus and a touch sensing method. The touch sensing apparatus includes a driving circuit unit applying a driving signal to at least one of a plurality of first electrodes; a sensing circuit unit generating an analog signal by detecting variations in capacitance in second electrodes intersecting the at least one of first electrodes to which the driving signal is applied; and a signal converting unit converting the analog signal into a digital signal, wherein the driving circuit unit controls a frequency of the driving signal according to electric noise and determines a level of the driving signal according to a dynamic range of the signal converting unit.
