Abstract

Systems and methods for managing display power consumption are disclosed. In some embodiments first information is displayed in an available display area including a first portion of a display screen in a configuration having a set of portions. The set of portions includes the first portion of the display screen, which is configured in a powered-on state to perform display functions and receive user input, and a second portion of the display screen, which is configured in a powered-off state. Responsive to a user indication in the in the first portion, the second portion is added to the available display area by transitioning the second portion to the powered-on state to perform display functions and receive user input. Second information is displayed in the second portion.

displaying second information in the second portion;

receiving a graphical content data structure comprising content for display in the available display area;

selecting elements of the graphical content data structure for display in the available display area based at least in part on whether the second portion is in a powered-on state; and

responsive to a system event, removing the second portion from the available display area and returning the second portion to the powered-off state,

wherein the system event is one of a set comprising a power down or sleep signal.

9. The multifunction device of claim 8, further comprising:
