Patent number: 10803828Abstract: Systems, methods, and computer readable media to improve the operation of display systems are disclosed. In general, techniques are disclosed for dynamically adjusting backlight elements based on image content. More particularly, a backlight element's intensity may be targeted for boosting (i.e., increasing) based on content of the backlight element's corresponding image region, where after a check may be made to determine if the proposed increase is likely to risk generation of a halo. If the proposed intensity increase would risk a halo, the backlight element's proposed intensity may be dimmed. Repeating the boost/dim cycle in an iterative fashion permits an image to be displayed with brighter highlights and deeper blacks.Type: GrantFiled: February 24, 2017Date of Patent: October 13, 2020Assignee: Apple Inc.Inventors: Ameya Joshi, Marc Albrecht, Sean Chang, Tobias Jung
