Abstract: A self-capacitive touch sensor panel configured to have a portion of both the touch and display functionality integrated into a common layer is provided. The touch sensor panel includes a layer with circuit elements that can switchably operate as both touch circuitry and display circuitry such that during a touch mode of the device the circuit elements operate as touch circuitry and during a display mode of the device the circuit elements operate as display circuitry. The touch mode and display mode can be time multiplexed. By integrating the touch hardware and display hardware into common layers, savings in power, weight and thickness of the device can be realized.

Abstract: An electronic device is disclosed. The electronic device can sense touch on its touch screen while in a sleep state in a manner that allows the electronic device to respond to certain touch inputs, while consuming less power due to touch sensing than while in an awake state. For example, sensing touch during the sleep state can allow the electronic device to wake (e.g., transition from the sleep state to the awake state) in response to detecting a certain touch input (e.g., a tap or other touch input) on its touch screen while in the sleep state. Various ways for the electronic device to sense touch during the sleep state are disclosed.

Abstract: This application relates to an electronic device that includes a processor and a display assembly overlaid by a protective cover. The display assembly can include a touch detection system capable of detecting a touch event at the protective cover. The touch detection system can include a capacitance detector capable of detecting a change in capacitance and a location corresponding to the change in capacitance, and an applied force detector capable of detecting an amount and a location of a force applied to the protective cover that is associated with the touch event. The electronic device can include a moisture detector capable of detecting an amount of moisture present at the protective cover, where when the amount of moisture is greater than a threshold amount, the processor determines a position of the touch event based on detection signals provided by the capacitance detector and the applied force detector.
