Abstract
A touch panel includes a substrate and a plurality of sensing units. The sensing units are disposed on the substrate. Each sensing unit includes two sensing bars respectively having a first end and a second end. The sensing bars extend along a direction and cross a touch region. The second end of one of the sensing bars of each sensing unit is configured for receiving a first signal respectively. The first ends of the sensing bars of each sensing unit are electrically connected to each other and configured to receive a second signal. The second end of the other one of the sensing bars of each sensing unit is configured to receive a third signal respectively.
