  • Publication number: 20180284937
    Abstract: Combined force and proximity sensing is disclosed. One or more sensors can concurrently sense a force applied by an object on a device surface and a proximity of the object to the surface. In an example, a single sensor can sense both force and proximity via a resistance change and a capacitance change, respectively, at the sensor. In another example, multiple sensors can be used, where one sensor can sense force via either a resistance change or a capacitance change and another sensor can sense proximity via a capacitance change.

  • Publication number: 20180275820
    Abstract: The use of multiple stimulation signals having one or more frequencies and one or more phases to generate an image of touch on a touch sensor panel is disclosed. Each of a plurality of sense channels can be coupled to a column in a touch sensor panel and can have one or more mixers. Each mixer in the sense channel can utilize a circuit capable generating a demodulation frequency of a particular frequency. At each of multiple steps, various phases of one or more selected frequencies can be used to simultaneously stimulate the rows of the touch sensor panel, and the one or more mixers in each sense channel can be configured to demodulate the signal received from the column connected to each sense channel using the one or more selected frequencies. After all steps have been completed, the demodulated signals from the one or more mixers can be used in calculations to determine an image of touch for the touch sensor panel at each of the one or more frequencies.

  • Patent number: 9766745
    Abstract: Capacitive touch panels may include a plurality of positive voltage lines that are driven at a first phase.

  • Patent number: 9444453
    Abstract: Measuring an effect of body capacitance in a touch sensitive device is disclosed. This effect can be caused by poor grounding of a user or other objects touching the device or of the device itself. The device can operate in a stray capacitance mode to measure a body capacitance effect and in a normal mode to detect a touch on the device. During the stray capacitance mode, the device can obtain a body capacitance measurement from the device. During the normal mode, the device can obtain a touch measurement from the device. The device can calculate a body capacitance factor based on a ratio between the body capacitance measurement and the touch measurement and use the body capacitance factor to compensate for erroneous or distorted touch output values from the device. Various components of the device can be switchably configured according to the particular mode.
