Abstract
Energy-aware software control in a computer system requires a display capable of supporting control of individual portions thereof so at to reduce its energy consumption. The energy-aware software control involves profiling screen usage patterns and their impact on the energy consumption by the display. The profiling results in an energy model. A determination is made when to prompt the energy-aware software control of the display. As well, a determination is made as to which screen portions of the display and what display parameters to control based on the energy model. Then, for each portion of the display to be controlled, controlling its display parameters, wherein the screen portions are controlled to attain energy conservation.

26. A system for energy-aware software control of a display in a computer system so as to reduce energy consumed by the display, comprising:
-
means for profiling screen usage patterns and their impact on energy consumption by the display, the profiling resulting in an energy model;
means for determining when to prompt the energy-aware software control of the display in order to decrease its energy consumption;
means for determining which screen portions of the display and what display parameters to control based on the energy model; and
for each portion of the display to be controlled, mans for controlling its display parameters, wherein the screen portions are controlled to attain energy conservation.

30. A system for energy-aware software control in a computer system, comprising:
-
a central processing unit (CPU);
a memory embodying program code to be fetched and executed by the CPU, the program code including that of applications;
a display capable of supporting fine-grained control of screen portions via their respective display parameters;
a user interface, the display and user interface being directly or indirectly controlled by the CPU;
a monitor configured to monitor power metrics of a computer system power source;
an energy model creator using as an input profiling parameters to create an energy model; and
an energy-aware software control means capable of controlling the respective display parameters of the screen portions based on the energy model, wherein the energy-aware software means is prompted based on indications from the monitor, applications and/or user interface.
