Abstract
A touch-sensitive display device includes one or more touch-sensitive displays each including a plurality of touch-sensitive electrodes. A free touch-sensitive electrode is identified on the one or more touch-sensitive displays that is (1) at least temporarily unaffected by proximity of one or more input objects to the one or more touch-sensitive displays, and (2) affected by an electrical noise caused by display of image content on the one or more touch-sensitive displays. The electrical noise affecting the free touch-sensitive electrode is measured. Based at least in part on the measured electrical noise affecting the free touch-sensitive electrode, and using a trained neural network, an amount of electrical noise caused by the display of image content that is affecting an occupied touch-sensitive electrode is estimated, the occupied touch-sensitive electrode being affected by proximity of the one or more input objects to the one or more touch-sensitive displays.
