Display with gaze-adaptive resolution enhancement

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) 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.
