Abstract
A near-eye display system includes a display panel, a beam steering assembly facing the display panel, a display controller, and a beam steering controller. The beam steering assembly imparts one of a plurality of net deflection angles to incident light. The display controller drives the display panel to display a sequence of images, and the beam steering controller controls the beam steering assembly to impart a different net deflection angle for each displayed image of the sequence. The sequence of images, when displayed within the visual perception interval, may be perceived as a single image having a resolution greater than the resolution of the display panel or having larger apparent pixel sizes that conceal the black space between pixels of the display, or the sequence of images may represent a lightfield with the angular information represented in the net deflection angles imparted into the images as they are projected.
