Abstract

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.
