摘要： A method for multi-touch integrity sensing for a multi-touch capacitive touch screen is disclosed. By determining the integrity of touches, a distinction is identified between wanted touches, such as via a finger or stylus, and unwanted touches such as via foreign matter, errors, and the like.

摘要： A system and method for multi-touch integrity sensing for a multi-touch capacitive touch screen determines a distinction between wanted touches, such as via a finger or stylus, and unwanted touches such as via foreign matter, errors, and the like. Mutual capacitance and self-capacitance sensing data is collected and processed to identify reference strengths and detection thresholds. If differences between mutual/self-capacitance strength and the corresponding reference strengths exceed the corresponding detection thresholds, then the touch is classified as an unwanted (for example, water) touch.

摘要： The present disclosure provides a capacitive sensing structure for detecting a force touch in a touchscreen application. Performance uniformity of the force touch sensor is improved by providing a capacitive force touch structure having sensing electrodes of varying thickness, wherein the variation in electrode thickness corresponds to a relative displacement potential of portions of the sensing electrode. This variation in thickness improves performance uniformity of the force sensor by compensating for the displacement potential (i.e., flexibility) of the sensing electrodes so that a force touch applied to the touch surface is measured consistently regardless of the location of the force touch on the touch surface.

摘要： An electronic device may include a touchscreen having sensing capacitors, and readout circuitry. The readout circuitry may be configured to accumulate a sample set from each sensing capacitor, divide the sample set into sample subsets, remove a given sample subset when the given sample subset exceeds a threshold, and process remaining sample subsets for touch input.
