Abstract
A display apparatus includes an electronic display having a pixel array configured to display a sequence of subframes, and an image shifting electro-optic device that is operable to shift at least a portion of an image of the display pixel array synchronously with displaying the sequence of subframes, so as to form a sequence of offset subframe images for providing an enhanced image resolution and pixel correction in a compound image. The image shifting electro-optic device may include a polarization switch in series with a polarization grating, for shifting image pixels between offset image positions in coordination with displaying consecutive subframes.
