Abstract

A display apparatus including an image renderer per eye; a liquid-crystal device including a liquid-crystal structure and a control circuit, the liquid-crystal structure being arranged in front of image-rendering surface of image renderer, wherein liquid-crystal structure is to be electrically controlled, via control circuit, to shift light emanating from a given pixel of the image renderer to a plurality of positions in a sequential and repeated manner; and at least one processor configured to render a sequence of output image frames via the image renderer, wherein a shift in the light emanating from the given pixel of the image renderer to the plurality of positions causes a resolution of the output image frames to appear higher than a display resolution of the image renderer.
