Abstract:
Methods and devices to conserve power on a mobile device determine an active region on a display and dimming a portion of the display backlight corresponding to the non-active regions. The method includes detecting an active region and a non-active region on a display. The detection may be based on a user interaction with the display or processing an image of the user to determine where on the display the user is looking. The method may control a brightness of a backlight of the display depending on the active and non-active region.
