First Claim
Patent Images
1. A method, comprising:
- detecting a triggering activity;
with a sensor, detecting a current ambient light level at a display device when the triggering activity is detected;
adjusting a brightness of the display device from a zero brightness level to a first brightness level when the current ambient light level is below a threshold; and
adjusting the brightness of the display device from the zero brightness level to a second brightness level when the current ambient light level meets or exceeds the threshold.

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.
