Abstract: In an embodiment, a system may include one or more processors forming central processing units (CPUs) in the system, a display controller configured to display frames on a display device, a memory controller configured to control a memory, and a power management circuit. The power management circuit may be configured to establish one of a plurality of power states in the system. In a first power state, the display controller and the memory controller are powered on while the CPUs are powered off. The display controller may be configured to read a plurality of prerendered frames from the memory and display the plurality of prerendered frames at times specified for each of the plurality of prerendered frames.

Abstract: An electronic device includes an enclosure (101) having a transparent cover (141) defining a touch-sensitive surface, a display (102) positioned within the enclosure and below the transparent cover, and a haptic device (103) configured to produce a haptic output along the touch-sensitive surface. The haptic device (103) may include a battery element (104) electrically coupled to the display (102), a magnetic element (220), and a coil assembly (106) fixed with respect to the enclosure (101) and configured to induce an oscillatory movement of the battery element (104) parallel to the display to produce the haptic output. In other examples, the coil assembly (106) may be coupled to the battery element (104) and first and second magnetic elements may be fixed with respect to the enclosure (101).
