Abstract
A position apparatus of a touch device and a position method thereof are provided, wherein the touch device includes a plurality of scan lines. In the position method, a plurality of capacitances in the scan lines are sensed. Next, a plurality of capacitances respectively sensed in an ith scan line of the scan lines and a subset of the scan lines neighboring with the ith scan line are selected. When the capacitance sensed in the ith scan line is larger than each of the capacitances sensed in the subset of the scan lines, the capacitance sensed in the ith scan line is determined as a peak capacitance. Finally, a touch position is calculated according to the peak capacitance and the capacitances sensed in the subset of the scan lines.
