Abstract: An embodiment method for operating an electronic device includes transmitting, from a controller, a tearing effect (TE) signal to a touchscreen over a first period of time, the first period of time occurring during a first frame and having a duration that is shorter than a period of the first frame, the TE signal being configured to restrict image data from being displayed on the touchscreen during the first period of time; displaying the first frame of a plurality of frames of the image data on a display of the touchscreen over a second period of time within the period of the first frame other than during the first period of time; and detecting, at the controller, a first touch by performing a first self-sensing scan during the first period of time.
