1. A display device comprising: a controller configured to receive a sequence of image frames constituting an initial image from an external image source and generate a control signal based on the sequence of image frames; a display configured to generate, based on the control signal, a spatial light distribution pattern corresponding to the sequence of image frames; a spatial-to-angular distribution transformer configured to transform the spatial light distribution pattern to an angular light distribution pattern and generate at least two parallax images associated with the sequence of image frames based on the angular light distribution pattern; an image relay and scanner configured to generate a fused image based on the at least two parallax images; and a screen configured to display the fused image.
