1. An electronic display comprising:

  • a light-releasing display surface extending across a flat face portion and around a curved corner portion of a display matrix;

    an image-correcting layer coupled to the light-releasing display surface, the image-correcting layer being configured to transmit light released from the flat face portion and to reorient light released from the curved corner portion such that the transmitted light and the reoriented light exit the image-correcting layer substantially in parallel, forming an apparent plane image of the flat face portion and the curved corner portion; and

    a luminance-correcting layer arranged between the light-releasing display surface and the image-correcting layer, the luminance-correcting layer being configured to deflect the light released from the curved corner portion into an acceptance profile of the image-correcting layer, wherein the luminance-correcting layer includes a subseries of prismatic structures with a plurality of facets arranged to reflect light from the light-releasing display surface onto an adjacent facet, which then refracts the light into the image-correcting layer.
