Abstract
Apparatuses and methods to operate a display device of an electronic device. In some embodiments, a method includes receiving a user setting or input of a display control parameter, and causing or altering, based on the user setting or input, an effect of an ambient light sensor value (ALS) on control of the display control parameter. The user input may be an unlock of a touch screen input capability of the display device, and a wake of the display device from an inactivity dim. Also, according to embodiments of the inventions, a method of operating a display of an electronic device includes receiving a change to one of a display brightness output level and an ambient light sensor output level, and altering, according to the change, a display brightness or contrast output level. Other apparatuses and methods and data processing systems and machine readable media are also described.

10. The method of claim above 6, wherein the ALS value is based on an amount of ambient light in the environment incident upon the display device;
- wherein the display control parameter is a physical brightness level of the display device; and
wherein the physical brightness level is sufficient to allow a user to see and identify text, images, and/or video displayed on the display.
- wherein the display control parameter is a physical brightness level of the display device; and

19. A method of operating a display device of an electronic device, the method comprising:
-
receiving an ambient light sensor (ALS) value change; if the change is an increase, automatically altering, based on the ALS value change, an effect of the ALS value change on control of the display control parameter; and if the change is a decrease, not automatically altering, based on the ALS value change, an effect of the ALS value change on control of the display control parameter. - View Dependent Claims (20, 21, 22, 23)
