Abstract:
1. A method of operating a display device of an electronic device, the method comprising: powering on the electronic device and the display device; as a result of powering on, displaying a first brightness level of the display device as one of a user selected brightness, or a predetermined brightness, wherein a plurality of different ambient light levels do not affect control of the brightness level of the display device after powering on, and prior to wake of the display device from an inactivity dim state; operating the display device in an on state in the inactivity dim state prior waking of the display device; receiving a user input requesting a wake of the display device from the inactivity dim, wherein the user input requesting a wake is a tap on a touch screen; as a result of the user input, waking the display device, wherein determining comprises: determining, as a result of the user input, whether an ambient light sensor (ALS) value affects control of a brightness level of the display device; if the ALS value is greater than a wake threshold, automatically causing, based on the ALS value, a first increase in the brightness level of the display device, wherein automatically causing occurs throughout a first range of the brightness level; and if the ALS value is less than the wake threshold, automatically causing, not based on the ALS value, a predetermined second increase in the brightness level of the display device, wherein automatically causing occurs throughout a second range of the brightness level, wherein the second increase is less than the first increase.
