Abstract
A bidirectional active stylus and a sensing system are provided. The stylus includes a receiving electrode, a first emitting diode and a second emitting diode. The receiving electrode is configured to receive a synchronous signal from a touch pad. The receiving electrode is disposed at a position closer to the touch pad with respect to the first emitting diode and the second emitting diode. The strength of received signals is improved.
