Reducing energy consumption of a display

A computer program product for reducing energy consumption by a display of an electronic device, the computer program product embodied on a computer readable storage medium having stored program instructions, wherein the computer readable storage medium is not a transitory signal per se, the program instructions executable by a processor to cause a computer to perform a method comprising:

• enabling, by a computer, a first illumination area of a display;
• receiving, by the computer, an input from a display adjustment application to adjust a second illumination area of the display when energy storage drops below a threshold, wherein adjusting comprises performing one or both of the following:
• disabling, by the computer, a portion of the first illumination area not included in the second illumination area;
• and
• enabling, by the computer, a portion of the second illumination area not included in the first illumination area.

An electronic device, comprising:

• a display configured to display a first illumination area and a second illumination area;
• one or more computer processors;
• one or more computer-readable storage media;
• program instructions stored on a computer-readable storage media for execution by at least one of the one or more processors, the program instructions comprising:
• instructions to enable the first illumination area of the display;
• instructions to receive an input from a display adjustment application to adjust the second illumination area of the display when energy storage drops below a threshold, 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.

An electronic display device, comprising:

• a display element, wherein the display element comprises:
• a plurality of light emitting devices configured to illuminate at least a portion of the display element, wherein the plurality of light emitting devices are controlled by
• one or more illumination control chips;
• one or more computer processors;
• one or more computer-readable storage media;
• program instructions stored on the computer-readable storage media for execution by at least one of the one or more processors, the program instructions comprising instructions to:
• activate a first set of the plurality of light emitting devices configured to illuminate a first light guide plate, by at least one illumination control chip, to display an image on a first illumination area of the display element;
• receive an input to adjust a second illumination area of the display illuminated by a second set of a plurality of light emitting diodes configured to illuminate a second light guide plate, wherein adjusting comprises performing one or both of the following:
• disabling, by at least one illumination control chip, light emitting devices in the first set within the first illumination area;
• and
• enabling, by at least one illumination control chip, light emitting devices within the second illumination area.
