A routing carrying display related signals (e.g., a source signal for sub-pixel updating) may induce a corrupting current into a routing for carrying capacitive sensing signals. This corrupting current would reduce the ability to determine presence of an input object via the sensing signal. Therefore, the corrupting signal is effectively removed by averaging sensing signals from two consecutive frames together. Because displays perform frame inversion, in which the voltage polarity provided to a sub-pixel for updates is reversed each frame, the corrupting current reverses in polarity each frame. Therefore, adding two subsequent frames together cancels out the corrupting signal."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Sensing frame averaging for cancelling display noise in simultaneous display and touch sensing","description":"Techniques for removing display-based corrupting components from a capacitive sensing signal when display and capacitive sensing is performed at or nearly at the same time.
