Abstract
Embodiments described herein include a method for avoiding display noise in a capacitive touch sensing device that includes sensing a touch input in a sensing region of an input device at a first touch sensing frequency. The method also includes analyzing incoming display data for display data noise at the first touch sensing frequency and at a second touch sensing frequency. If the display data noise at the first touch sensing frequency is higher than a threshold, touch sensing frequency is adjusted to the second touch sensing frequency where the display data noise is lower than the threshold. If the display data noise at the first touch sensing frequency is lower than the threshold, sensing is continued at the first touch frequency.
