Abstract
A capacitance sensing apparatus applied to a touch panel is provided. The capacitance sensing apparatus includes a plurality of sensor channels including a first sensor channel and a second sensor channel neighboring to each other. A first voltage signal is outputted to the first sensor channel. A plurality of capacitances of the first sensor channel are detected to generate a first capacitance result for touch sensing. A second voltage signal is outputted to the second sensor channel. A first voltage difference is present when the first voltage signal and the second voltage signal are respectively outputted to the first sensor channel and the second sensor channel, and a second voltage difference is present when the capacitance of the first sensor channel. The first voltage difference and the second voltage difference are substantially the same.
