    摘要： In a method of operating a touch screen, an object interaction is detected with the touch screen while in a first doze mode. It is determined if a detected object interaction with the touch screen is a valid input object interaction with the touch screen. In response to determining the object interaction is a valid input object interaction, the touch screen is transitioned from the first doze mode to a gesture recognition mode. The touch screen is transitioned from the gesture recognition mode to an active mode in response to a determination of a valid gesture interaction with the touch screen by the input object.

    摘要： Devices, systems, and methods are provided for coordinating the interaction between a touch screen controller and a display controller in an electronic device of the type including a host processor, a touch screen controller configured to acquire capacitive measurements from a touch screen, and a display controller configured to update a display at a refresh frequency and phase. The method includes: sharing a synchronization signal between the display controller and the host processor, the synchronization signal indicative of the refresh frequency and phase; polling the touch screen controller, by the host processor, based on the synchronization signal; and in response to the polling, acquiring the capacitive measurements by the touch screen controller at a sampling rate and phase determined by the refresh frequency and phase.
