Abstract: Energy savings and device efficiency aspects have become increasingly important in mobile device design. Displays are responsible for a large portion of modern mobile multimedia device power consumption, and thus, traditional power management methods often rely on shutting off the display for inactive periods. Since the multimedia consumption is becoming the prominent use case for a mobile device, this logic does not apply for power savings any more. The focus needs to shift to making the device itself more power-efficient. This Chapter describes some of the power management principles for modern mobile multimedia displays.
