  • Patent number: 11450297
    Abstract: An electronic device such as a head-mounted device may have a display that is viewable by a user from eye boxes. The electronic device may have a gaze tracking system that monitors a user's eyes in the eye boxes to gather gaze direction information. The display may have a central portion and a peripheral portion. The peripheral portion may have a lower resolution than the central portion and may be used in displaying content that is viewable in a user's peripheral vision. During operation, control circuitry in the electronic device may adjust peripheral content on the peripheral portion to correct for parallax-induced mismatch between the peripheral content and central content on the central portion of the display. The control circuitry may also depower peripheral pixels that are determined to be unviewable based on the gaze direction. Diffusers may be used to hide seams between the central and peripheral display portions.
