摘要:
There are provided a touch sensing apparatus and method. The touch sensing apparatus includes a sensing circuit unit detecting a plurality of signals from a plurality of changes in capacitance generated in a plurality of electrodes provided in a panel unit; and a signal processing unit comparing, with predetermined reference levels, levels of at least two signals generated from changes in capacitance in at least two electrodes spaced apart from one another by a predetermined distance or greater, from among the plurality of electrodes, wherein, when the levels of the at least two signals are greater than the predetermined reference levels, the plurality of changes in capacitance are determined to be generated due to noise.
