Abstract
A touch-sensitive display device includes a first touch-sensitive display including a first plurality of display electrodes configured to detect proximity of input objects to the first touch-sensitive display, and a second touch-sensitive display including a second plurality of display electrodes configured to detect proximity of input objects to the second touch-sensitive display. A touch controller detects a non-stylus touch input at a first display electrode of the first touch-sensitive display based on a first signal from the first display electrode, and a stylus touch input from a stylus at a second display electrode of the second touch-sensitive display based on a second signal from the second display electrode. A two-dimensional position of the stylus touch input is determined relative to the second touch-sensitive display based at least on the second signal and noise compensation derived from the first signal.
