  • Patent number: 10416802
    Abstract: Disclosed is a touch sensor and method for detecting a touch in a capacitive touchscreen application, wherein the touch sensor is capable of distinguishing between a finger hovering above the touch sensor and a touch from a stylus having a small contact surface area without having to adjust the sensitivity of the touch sensor. The touch sensor includes a first sensing electrode, a transmit electrode, and a second sensing electrode, wherein the second sensing electrode is positioned substantially around the perimeter of the inner circuitry (i.e., transmit electrode and first sensing electrode). A touch is detected by sensing changes in a first capacitance between the transmit electrode and first sensing electrode and a second capacitance between the transmit electrode and second sensing electrode. The changes in the first and second capacitances are compared to determine whether the changes in the capacitances are due to a finger hover or a touch.

  • Publication number: 20170102758
    Abstract: A touch screen controller provides a host interrupt to a host device operating in a low power consumption mode. The touch screen controller uses gesture templates to detect gestures input via a touch screen. Each gesture template is associated with an event identifier, and each event identifier is associated an application. Each gesture template includes a template identifier, a matching threshold, a criterion, and coordinates corresponding to locations on the touch screen panel. If at least one of the coordinates corresponding to a gesture input via the touch screen satisfies the criterion included in a particular gesture template, the touch screen controller provides a host interrupt with the event identifier corresponding to that gesture template to the host device. In response to receiving the host interrupt with the event identifier, the host device exits the low power consumption mode and opens the application associated with the event identifier.
