Abstract:
A touch-sensitive device with stylus includes a touch panel, a stylus drive unit, a touch panel sense unit, and a measurement unit. A touch by a stylus proximate to a touch panel electrode changes a capacitive coupling between the touch panel electrode and a stylus electrode. The amplitude of the response signal is responsive to the capacitive coupling between the touch panel electrode and the stylus electrode, and is measured to provide an indication of the position of the stylus electrode relative to the touch panel.
