Backlight and ambient light sensor system
First Claim
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.

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.

12. A non-transitory tangible machine readable medium containing executable program instructions which when executed cause a method of operating a display device of a data processing system, 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 to 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; 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, wherein determining comprises; 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. - View Dependent Claims (13, 14, 15, 16, 17, 18)
