Abstract
A touch-sensitive display device includes a touch sensor having a plurality of touch-sensing electrodes and control logic coupled to the plurality of touch-sensing electrodes. The control logic is configured to, in a non-reference time frame and based on a spatial capacitance measurement received for a first stylus electrode of an active stylus, estimate a non-reference time frame location of the first stylus electrode relative to the plurality of touch-sensing electrodes. In a reference time frame, based on a spatial capacitance measurement received for a second stylus electrode of the active stylus, a reference time frame location of the second stylus electrode is estimated. Based on an estimated velocity of the first stylus electrode, the non-reference location of the first stylus electrode is velocity corrected to give a reference time frame location of the first stylus electrode.
