Luminescence Shock Avoidance in Display Devices
First Claim
1. A method of operating an electronic device, the method comprising:
- with a sensor in the electronic device, detecting an ambient light level;
with processing circuitry in the electronic device, comparing the detected ambient light level to a threshold; and
activating a display in the electronic device, wherein when the detected ambient light level is less than the threshold, activating the display comprises at least temporarily shifting a color of light emitted by the display.

Abstract
A luminescence shock avoidance algorithm selectively limits the brightness level of a display device when the display device is activated in a dark environment to prevent the temporary vision impairment that can occur when a display device is activated in a dark environment. The algorithm receives the state of the display (e.g. on or in standby mode), and can optionally receive an ambient lighting value from an ambient light sensor and a user-selectable manual brightness adjustment setting to determine whether luminescence shock avoidance should even be triggered, and if it is triggered, how much should the brightness level of the display be limited.

9. An electronic device, comprising:
-
a display that emits light; a sensor that detects an ambient light level at the electronic device; processing circuitry that determines whether the detected ambient light level is less than a threshold; and gamma-shift logic that performs a gamma-shift operation to adjust the light emitted by the display when the processing circuitry determines that the detected ambient light level is less than the threshold. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16)

17. A method for operating an electronic device, comprising:
-
detecting a triggering activity; in response to detecting the triggering activity, activating an ambient light sensor in the electronic device; detecting an ambient light level with the ambient light sensor; comparing the detected ambient light level to a threshold value; and activating a display in the electronic device based on the comparison between the detected ambient light level and the threshold value, wherein activating the display comprises limiting an initial brightness of the display to an initial brightness level that is based on the detected ambient light level. - View Dependent Claims (18, 19, 20)
