Opportunistically changing display brightness
First Claim
1. In a computing environment, a method of automatically changing a brightness of a display device, the method comprising:
- while the display device is at a first brightness power output level, detecting a power saving event indicating that it is desirable to reduce overall power consumed by the display device;
as a result of detecting the power saving event, continuing to operate the display device at the first brightness power output level while attempting to identify a brightness power output level change triggering event, the first brightness power output level change triggering event is an event that is at least one of a change in ambient lighting or a change in screen output of the display device, the brightness power output level change triggering event is an event which masks changes to brightness power output level of the display device;
detecting the brightness power output level change triggering event; and
in response to detecting the brightness power output level change triggering event and the power saving event, changing the a the first brightness power output level of the display device during the brightness power output level change triggering event from the first brightness power output level to a second brightness power output level.

Abstract
Automatically changing the brightness of a display device. A method includes, while the display device is at a first brightness power output level, detecting a power saving event indicating that it is desirable to reduce overall power consumed by the display device. The method further includes continuing to operate the display device at the first power output level while attempting to identify a brightness power output level change triggering event. The brightness power output level change triggering event is an event that occurs that makes a change to the brightness power output level of the display device less perceptible to a user. The method further includes detecting a brightness power output level change triggering event. In response to detecting the brightness power output level change triggering event, the method includes changing the power output level of the display device to a second brightness power output level.

15. In a computing environment, a method of managing power output to a display device, the method comprising:
-
while the display device is at a first brightness power output level, detecting a power saving event indicating that it is desirable to reduce overall power consumed by the display device; then, as a result of detecting the power savings event, continuing to operate the display device at the first brightness power output level; then, identifying a first brightness power output level change triggering event that would ordinarily cause the display device to have a second brightness power output level where the first brightness power output level change triggering event is an event that is at least one of a change in ambient lighting or a change in screen output of the display device, the first brightness power output level change triggering event is an event which masks changes to a brightness power output level of the display device; and then, as the result of detecting the power saving event continuing to operate the display device at the first brightness power output level. - View Dependent Claims (16, 17, 18)

19. A device comprising:
-
a display device; one or more hardware processors configured to implement on the display device; a first signal detector that is configured to, while the display device is at a first brightness power output level, detect a power saving event indicating that it is desirable to reduce overall power consumed by the display device; a brightness level manager configured to continue to operate the display device at the first brightness power output level while, as a result of the power saving event, attempting to identify a brightness power output level change triggering event, where the brightness power output level change triggering event is an event that is at least one of a change in ambient lighting or a change in screen output of the display device, the brightness power output level change triggering event is an event which masks changes to brightness power output level of the display device; a second signal detector that is configured to detect the brightness power output level change triggering event; and wherein the brightness level manager is configured to, in response to detecting the brightness power output level change triggering event and the power saving event, change the brightness power output level of the display device during the brightness power output level change triggering event from the first brightness power output level to a second brightness power output level. - View Dependent Claims (20)
