Luminescence Shock Avoidance in Display Devices

摘要

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.

主权项

1. A method, comprising:
activating a display in an electronic device, wherein activating the display comprises:
with a sensor in the electronic device, detecting a current ambient light level at the display; andafter detecting the current ambient light level, increasing a brightness of the display to an initial brightness level that is at least partly based on the current ambient light level.
