摘要： A touch sensor panel configured to minimize the effect on touch or proximity event detection caused by a common mode noise event. The touch sensor panel includes circuitry that works to minimize the amount of time that the touch sensor panel is unable to accurately sense touch and proximity events due to a common mode noise event. The touch sensor panel can also re-acquire data that was collected during the time that the sensor panel was unable to accurately detect touch and proximity events, when a common mode noise event is detected.

摘要： Styluses capable of generating stylus stimulation signals and touch sensitive devices capable of receiving stylus stimulation signals are disclosed. In one example, a stylus can receive a stimulation signal from a touch sensor of a touch sensitive device and generate a stylus stimulation signal by changing an amplitude or frequency of the received stimulation signal. The stylus can transmit the stylus stimulation signal back into the touch sensor of the touch sensitive device. The touch sensor can generate a touch signal based on the device's own stimulation signals and the stylus stimulation signal. The touch sensitive device can process the touch signal to determine a location of the stylus on the touch sensor. The stylus can include a force sensor to detect an amount of force applied to a tip of the stylus. The stylus stimulation signal can be modulated based on the force detected by the force sensor.

摘要： The formation of metal traces in the border areas of a touch sensor panel to provide improved reliability, better noise rejection, and lower manufacturing costs is disclosed. The metal traces can be coupled to rows on the touch sensor panel in an interleaved manner, so that any two successive rows can be coupled to metal traces in border areas on opposite sides of the touch sensor panel. In addition, by utilizing the full width available in the border areas in some embodiments, the metal traces can be formed from higher resistivity metal, which can reduce manufacturing costs and improve trace reliability. The wider traces can also provide better noise immunity from noise sources such as an LCD by providing a larger fixed-potential surface area and by more effectively coupling the drive lines to the fixed potential.

摘要： A touch panel configured to compensate for negative pixel effect is disclosed. The panel can be configured to increase a capacitive sense signal, indicative of a touching or hovering object, in order to compensate for an increase in negative capacitance when the object is poorly grounded. To perform the compensation, the panel can be configured to have split sense lines so as to increase the number of electric fringe fields forming the sense signal, thereby providing a sense signal that is substantially stronger than the negative capacitance signal. Each sense line can be split into two or more strips.

摘要： Methods and apparatus for correcting electrical noise coupling from a liquid crystal module to a plurality of sense elements disposed within a touch sensor panel, and for reducing errors in touch detection algorithms. Erroneous signal values detected by the sense elements may be corrected by utilizing a set of reference elements for detecting noise common to both the sense elements and the reference elements, and a correction module for effectively subtracting out the noise from the sensed values. Errors in touch detection algorithms may be reduced by providing a more uniform spacing between successive sense elements. In some embodiments, one or more dummy ground elements may be inserted between adjacent sense elements in order to reduce signal interference.

摘要： A touch sensor panel is disclosed. The touch sensor panel includes a plurality of rows, at least one of the rows being a split row including a plurality of row subsections; and a plurality of columns, at least one of the columns being a split column including a plurality of column subsections. The touch sensor panel is configured with at least one split row and at least one split column located to increase a likelihood that a touch anywhere on the touch sensor panel overlaps with at least one split row and at least one split column. The rows and columns are individually charged electrodes capable of detecting a change in capacitance in a corresponding area of the touch sensor panel.
