Abstract:
This relates to a method for controlling illumination of a display screen on a mobile device. A light source is turned on to illuminate the display screen. An amount of information displayed on the display screen is identified. An amount of time to keep the light source turned on is determined based at least in part on the identified amount of information. The light source is kept turned on at a first intensity level for the amount of time and then turned to a second intensity level.
