摘要： A capacitive panel is scanned with an AC signal having pulses at a first frequency to produce a first frame of mutual capacitance data and pulses at a second frequency, different from the first frequency, to produce a second frame of mutual capacitance data. If neither the first nor second frames of mutual capacitance data is perturbed by noise, then data of the first and second frames of mutual capacitance data is averaged. The averaged data is then used in centroid processing.

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： An electronic device described herein includes a touch screen for a touch sensitive display carried by a portable housing. The electronic device is configured to operate in a high. detection threshold mode to determine whether an object is in contact with the touch sensitive display, and operate in a low detection threshold mode to determine whether the object is adjacent to the touch sensitive display, based on lack of detection of the object being in contact with the touch sensitive display. The electronic device is further configured to determine whether the object is in contact with a peripheral edge of the portable housing by determining whether the object is adjacent opposite sides of the touch sensitive display, based on detection of the object being adjacent to the touch sensitive display.

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： In an example, a display device includes a rollable display including a display side and an opposite non-display side. The rollable display includes a conductive material with a pattern disposed on the non-display side. The device includes a housing configured to house the rollable display and configured to roll in and roll out the rollable display along a first direction, and a capacitive sensor including a transmitter and a receiver electrode disposed within the housing and configured to sense the pattern.

摘要： A data frame in a touch capacitive sensing circuit includes both mutual capacitance data and self capacitance data. The mutual capacitance data and self capacitance data of the frame are filtered to define mutual capacitance and self capacitance islands. Centroids of the mutual capacitance and self capacitance islands are calculated and then processed in a weighted mixing operation to produce a hybrid centroid that more accurately locates the coordinates of a detected touch/hover.

摘要： A capacitive touch matrix has first conductive row elements spaced apart from one another, and first row interconnection circuitry electrically connects the first conductive row elements. Second conductive row elements are spaced apart from one another, and second row interconnection circuitry electrically connects the second conductive row elements. First conductive column elements are positioned between two adjacent ones of the first conductive row elements, the first conductive column elements being spaced apart from one another. Second conductive column elements are positioned in a same column as the first conductive column elements and between the two adjacent ones of the first conductive row elements, the second conductive column elements being spaced apart from one another. First column interconnection circuitry electrically connects each first conductive column element, and second column interconnection circuitry electrically connects each conductive column element. The conductive elements and interconnection circuitries are coplanar with one another.
