Abstract

A touch panel includes a substrate, a sensing circuit, a circuit board module and a wireless circuit. The sensing circuit is disposed in a first area on a surface of the substrate and configured to receive a touch signal on the touch panel. The wireless circuit is disposed in a second area on the surface or disposed on a connection part of the circuit board module, and configured to receive/transmit a wireless signal. An electronic apparatus is also provided. A wireless circuit of the electronic apparatus includes a first antenna and a second antenna, which are disposed adjacent to a front side and a back side of the electronic apparatus, respectively. The wireless circuit is configured to receive/transmit a wireless signal selectively in the direction of the front side through the first antenna or in the direction of the back side through the second antenna.
