Abstract
A sensing apparatus and a scan driving method thereof are provided. The sensing apparatus includes first and second electrodes, a sensing element array, first and second electrode scan driving circuits and a control circuit. The sensing element array outputs at least one first inductive voltage after being touched. The first electrode scan driving circuit sequentially scans and drives the first electrodes, wherein the driven first electrode is set to a high level output state and the first electrode not being driven is set to a low level output state or a grounding state. The second electrode scan driving circuit sequentially scans and drives the second electrodes, wherein the driven second electrode is set to high impedance (input) state, and the second electrode not being driven is set to a low level output state or the grounding state. The control circuit controls the first and second electrode scan driving circuits.
