Patent attributes
A head-mounted display includes an electronic display, a liquid crystal (LC) array with LC cells forming a dynamic lens array, an optical assembly, an eye tracker, and a controller. The LC array refracts image light emitted from the electronic display. The LC array includes a gaze region with a subset of the LC cells forming a portion of the dynamic lens array having a lens density different than that associated with remaining portions of the LC cells outside the gaze region. The eye tracker tracks a gaze location corresponding to a foveal region of a user's eye. The controller generates emission instructions and provides the emission instructions to the LC array to change location of the gaze region in the LC array based on the tracked gaze location. The optical assembly directs portions of image light refracted by the gaze region toward the foveal region of the user's eye.
