Reducing energy consumption of a display
Embodiments disclosed herein provide systems, methods, and computer program product for managing power consumption of a display. An illumination area of the display may be adjusted to limit or increase a number of activated light emitting devices, and thus, adjust power consumption of the display. A device may receive an input to adjust the first illumination area to the second illumination area. In response, a device may, for example, disable a portion of the first illumination area not included in the second illumination area. In another example, a device may enable a portion of the second illumination area not included in the first illumination area. An amount of operation time and/or energy storage may be calculated, based at least in part on a resize of an illumination area of the display.
1. A method for reducing energy consumption by a display of a computing device, comprising:
enabling a first illumination area of the display;
receiving an input to adjust a second illumination area of the display, wherein adjusting comprises performing one or both of the following:
disabling a portion of the first illumination area not included in the second illumination area; and
enabling a portion of the second illumination area not included in the first illumination area;
calculating an amount of energy storage available for the computing device based at least in part on one or more of:
the disabled portion of the first illumination area; and
the enabled portion of the second illumination area.
2. The method of claim 1 , further comprising displaying an image on one or more of:
the first illumination area on the display; and
the second illumination area on the display.
3. The method of claim 1 , wherein the display comprises:
a first set of one or more light emitting diodes in the first illumination area; and
a second set of one or more light emitting diodes in the second illumination area.
4. The method of claim 1 , wherein disabling a portion of the first illumination area not included in the second illumination area comprises:
a first illumination control chip disabling a first set of light emitting devices in at least the portion of the first illumination area not included in the second illumination area.
5. The method of claim 1 , further comprising:
scaling an image to fit the second illumination area, wherein prior to the scaling, the image is sized to fit the first illumination area.
6. The method of claim 1 , wherein receiving the input to adjust the second illumination area comprises:
receiving an input via a user input indicating a size of the second illumination area on the display.
7. The method of claim 1 , wherein receiving the input to adjust the second illumination area comprises:
receiving an input via a user input indicating a location of the second illumination area on the display.
8. The method of claim 1 , wherein receiving the input to adjust the second illumination area comprises:
receiving an input from a display adjustment application when energy storage drops below a threshold.
