Abstract
Embodiments of a device having a touchscreen panel and method for reducing power consumption are generally described herein. The touch-sensing capability of the touchscreen panel is activated when user interaction with the touchscreen panel is detected. The touch-sensing capability of the touchscreen panel is deactivated when no user interaction is detected. In some embodiments, the device includes a touch-event detector to sense motion or vibration, and processing circuitry to either activate or deactivate touch-sensing capability of the touchscreen panel based at least in part on input from the touch-event detector.
