Abstract
Stylus tip configurations may reduce shadow effect of the stylus tip on capacitance measurements by reducing capacitive coupling between undesired portions of the stylus tip and the capacitive sensing surface. Additionally signal-to-noise ratio (SNR) of a stylus on a plurality of capacitance sensing electrodes may be improved by reducing the self capacitance between the stylus tip and the receive electrodes of a mutual capacitance touch screen.
