Abstract
An active stylus includes at least one electrode, and an integrated circuit coupled to the at least one electrode. The integrated circuit is configured to: operate in a first mode to unilaterally transmit signals to a sensor controller from one of the at least one electrode; determine whether a pen tip of the active stylus is in contact with a sensor panel; responsive to determining that the pen tip is in contact with the sensor panel, transmit a pen pressure value of the pen tip; and responsive to determining that the pen tip is not in contact with the sensor panel, instead of transmitting the pen pressure value, detect an uplink signal transmitted from the sensor panel.
