1. A computing device, comprising:
- a display;
a UV light sensor;
a memory storing a default brightness setting;
a processor; and
a display brightness program executable by the processor, the display brightness program configured to;
set the default brightness setting to an indoor light output level;
activate the UV light sensor to detect UV radiation levels;
while the display is deactivated, determine that one or more of the UV radiation levels goes above a UV threshold;
based on determining that one or more of the UV radiation levels goes above the UV threshold, update the default brightness setting to an updated default brightness setting that corresponds to an outdoor light output level that is greater than the indoor light output level;
activate the display from the deactivated state to illuminate at the updated default brightness setting corresponding to the outdoor light output level; and
wherein the UV threshold is a positive non-zero value.

Abstract
Computing devices and methods for controlling light output of a display are disclosed. In one example, a default brightness setting is set to an indoor light output level. A UV light sensor is activated to detect UV radiation levels. Based on determining that one or more of the UV radiation levels exceed a UV threshold, the default brightness setting is updated to correspond to an outdoor light output level that is greater than the indoor light output level. Without using information from an ambient light sensor, the display is activated from a deactivated state to illuminate at the updated default brightness setting corresponding to the outdoor light output level.

10. A method for controlling light output of a display in a computing device, the method comprising:
-
setting a default brightness setting in a memory of the computing device to an indoor light output level; activating a UV light sensor to detect UV radiation levels; while the display is deactivated, determining that one or more of the UV radiation levels goes above a UV threshold; based on determining that one or more of the UV radiation levels goes above the UV threshold, updating the default brightness setting to an updated default brightness setting that corresponds to an outdoor light output level that is greater than the indoor light output level; without using information from an ambient light sensor, activating the display from the deactivated state to illuminate at the updated default brightness setting corresponding to the outdoor light output level; and wherein the UV threshold is a positive non-zero value. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17, 18)

19. A wearable computing device, comprising:
-
a display; an ambient light sensor; a UV light sensor; a memory storing a default brightness setting and a default display dimming period; a processor; and a display brightness program executable by the processor, the display brightness program configured to; set the default brightness setting to an indoor light output level; activate the UV light sensor to detect UV radiation levels; while the display is deactivated, determine that one or more of the UV radiation levels goes above a UV threshold; based on determining that one or more of the UV radiation levels goes above the UV threshold; update the default brightness setting to an updated default brightness setting that corresponds to an outdoor light output level that is greater than the indoor light output level; and update the default display dimming period to an updated default display dimming period that is shorter than the default display dimming period; without using information from the ambient light sensor and in response to a display activation command at an activation time, activate the display from the deactivated state to illuminate at the updated default brightness setting corresponding to the outdoor light output level; reduce a light output of the display upon an expiration of the updated default display dimming period as measured from the activation time; and wherein the UV threshold is a positive non-zero value. - View Dependent Claims (20)
