1. An apparatus comprising:
- an electronic display comprising a pixel array configured to display a frame, the pixel array comprising a plurality of display pixels;
an eye tracking device configured to determine a gaze direction of a user of the electronic display; and
,an optical block for forming a frame image from the frame displayed by the electronic display, the optical block comprising a segmented resolution enhancing device (SRED) disposed in an optical path of light from the display pixels and operatively coupled to the eye tracking device, the frame image comprising an array of image pixels disposed at an image pixel pitch p;
wherein the SRED comprises a plurality of device segments configured to be individually activated in response to a signal from the eye tracking device, each device segment being optically coupled to a different group of display pixels of the pixel array, for selectively enhancing effective resolution for a portion of the frame image in the gaze direction;
wherein each device segment from the plurality of device segments comprises a light steering switch (LSS) configured to switch, upon activation in response to the signal, between two or more light steering states while the frame is being displayed, so as to provide a sequence of offset images for the portion of the frame image in the gaze direction.

Abstract
A display apparatus includes a pixelated display, an eye tracking system, and a segmented resolution enhancing device coupled to the eye tracking system and operable to selectively enhance effective image resolution for the electronic display in the gaze direction. The segmented resolution enhancing device may include a polarization switch in series with a polarization gratings, at least one of which is segmented, for shifting image pixels in the gaze direction between offset positions while displaying a frame.
