Abstract:
There is provided a capacitance sensing apparatus including: a driving circuit unit sequentially applying a driving signal to each of a plurality of first electrodes; a sensing circuit unit including a first integrating circuit detecting a first change in capacitance generated in a plurality of second electrodes by the driving signal and a second integrating circuit connected to another first electrode adjacent to the first electrode to which the driving signal is applied; and an operating unit connected to the sensing circuit unit to determine a touch input, wherein the second integrating circuit detects a second change in capacitance generated due to noise in the another first electrode, and the operating unit determines the touch input based on the first and second changes in capacitance.
