Abstract
An electronic device may have a display layer for displaying images. An optical coupling layer having an input surface that receives light from the display panel may convey the light from the input surface to an output surface. The output surface may have different dimensions than the display layer and may have any desired shape. To account for the displacement of light between the active area and the outer surface of the optical coupling layer and to ensure the output image is perceived with the desired distortion, image data may be rendered for the output surface then modified to account for the distortion and displacement that will occur later when the image is transported by the optical coupling layer from the display active area to the output surface of the optical coupling layer. Image distortion control circuitry may modify the rendered image data based on a distortion map.
