1. A mobile device comprising:
a first touch controller in a first display;
a second touch controller in a second display;
an interlink coupling the first touch controller to the second touch controller;
power management logic separately executed by each of the first touch controller and the second touch controller, the power management logic being executable to operate a touch system in each display to:
selectively toggle the touch system in the display from a high power state to a low power state independent of a power state of the touch system in the other display; and
selectively toggle the power state of the touch system in the display from the low power state to the high power state responsive to an interrupt received across the interlink, the interrupt being a signal state change corresponding to reversal in polarity of a signal transmitted across the interlink.
