Abstract
A touch panel includes a substrate, scan lines, data output lines, a signal processing unit and touch sensing units. Each touch sensing unit includes a sensing electrode, a reference capacitor, an output circuit and a reset circuit. The sensing electrode is disposed in a breach of the sensing electrode. The reference capacitor, the output circuit and the reset circuit are disposed on the substrate and in the breach. The output circuit, the reset circuit, the reference capacitor and the sensing electrode are electrically coupled to a reference point. The output circuit is configured to output touch signals to the corresponding data output line. The signal processing unit is configured to obtain electric potential of the data output line and perform a corresponding processing step. When the touch sensing unit is out of working, the reference point is reset to a predetermined electric potential.
