A display system (100) for displaying an interlaced image frame (122), having a top field (120) and a bottom field (121), includes an image processing unit (106) configured to process a stream of pixel data corresponding to the top and bottom fields (120,121) and generate a number of image sub-frames, a modulator (103) configured to generate a light beam bearing the number of image sub-frames, and a wobbling device (104) configured to displace the light beam such that each of the number of image sub-frames is spatially displayed in an image sub-frame location offset from image sub-frame locations of others of the image sub-frames. The image processing unit (106) processes the pixel data corresponding to the top field (120) to generate at least one of the number of image sub-frames and the pixel data corresponding to the bottom field (121) to generate at least one of the number of image sub-frames.
