Abstract
An active stylus includes a stylus electrode configured to electrostatically couple with one or more electrodes of a display device having a capacitance-based touch sensor, transmit logic configured to drive the stylus electrode with a synchronization waveform that is configured, via interpreting a response on one or more electrodes of a first display device, to enable the first display device to become time synchronized with the active stylus in a stylus-initiated synchronization mode, receive logic configured to interpret a response on the stylus electrode caused by a synchronization waveform being driven on one or more electrodes of a second display device, to enable the active stylus to become time synchronized with the second display device in a display-initiated synchronization mode, and a controller configured, in response to detection of a condition, to cause the active stylus to switch from one of the synchronization modes to the other.
