摘要： An elongated stylus is configured to be capacitively coupled with a sensor array providing a plurality of electrodes to indicate a position on the sensor array. The stylus includes a housing having an end in an elongated direction of the housing, a conductive tip disposed at least partially extended from the end of the housing, an electrode disposed around the conductive tip and configured to at least partially expose the conductive tip, and a signal transmit drive circuit configured to provide a signal. Control is performed to form an electrical connection between the electrode and a ground and an electrical connection between the electrode and the signal transmit drive circuit when the elongated stylus is activated for capacitive coupling with the sensor array.

摘要： A system comprises a processing device and a capacitive sense array that includes a plurality of electrodes. The system receives a first signal from a first scan of electrodes in a capacitive sense array. The system processes the first signal using a first set of sequences to detect a stylus. The system receives a second scan from a second scan of electrodes in a capacitive sense array. The system processes the second signal using a second set of sequences to detect the stylus.

摘要： A system and method for synchronizing a stylus to a capacitive sense array. The system including a capacitive sense array which includes a plurality of electrodes. A synchronization signal is transmitted to the stylus using the plurality of electrodes. The synchronization signal is transmitted to the stylus by capacitively coupling the stylus to the capacitive sense array.

摘要： A stylus detecting system includes a sense array including N number of first lines and M number of second lines crossing the N number of first lines; and a touch controller connected to the sense array and configured to: (i) in a touch object detecting mode, drive the N number of first lines as transmission (TX) lines with a finger sensing TX signal and measure reception (RX) signals on the M number of second lines as RX lines, and (ii) in a stylus detecting mode, measure a stylus TX signal transmitted by a stylus, on both the N number of first lines and the M number of second lines, using #number of multiple RX channels (#RX channels) to sense more than one line of the first and second lines at the same time, such that a complete stylus scan includes (N+M)/(#RX channels) number of scans.

摘要： An elongated stylus is configured to be capacitively coupled with a sensor array providing a plurality of electrodes to indicate a position on the sensor array. The stylus includes a housing having an end in an elongated direction of the housing, a conductive tip disposed at least partially extended from the end of the housing, an electrode disposed around the conductive tip and configured to at least partially expose the conductive tip, and a signal transmit drive circuit configured to provide a signal. Control is performed to form an electrical connection between the electrode and a ground and an electrical connection between the electrode and the signal transmit drive circuit when the elongated stylus is activated for capacitive coupling with the sensor array.
