Abstract:
Methods and devices useful in discharging an aberrant charge on a touch sensitive display of an electronic device are provided. By way of example, a an electronic device includes a power management and control circuitry configured to receive a first voltage signal and a second voltage signal from a display subsystem of a display of the electronic device, receive a third voltage signal from a touch subsystem of the display, provide a power signal to the display subsystem to activate the display subsystem when the display is determined to be in a temporarily inactive state. Providing the power signal to the display subsystem comprises discharging an aberrant charge based on the third voltage signal.
