Electronic device displays with curved surfaces

An electronic device comprising:

• a display cover layer with first and second opposing edges that couple to third and fourth opposing edges to form four corner regions;
• and
• a display panel that is covered by the display cover layer, wherein the display panel has a planar central portion, a first display panel extension that extends from the planar central portion along the first edge and that is bent relative to the planar central portion, and a second display panel extension that extends from the first display panel extension into one of the four corner regions, and wherein the planar central portion, the first display panel extension, and the second display panel extension include pixels.

A method of forming a plurality of fibers that are configured to guide light from display pixels in a display panel to a curved interior surface of a display cover layer in an electronic device, the method comprising:

• forming a layer of photoactive material;
• and
• with at least one light source, activating portions of the photoactive material, wherein each activated portion of the photoactive material forms a respective fiber of the plurality of fibers.

An electronic device comprising:

• an array of organic light-emitting diode pixels;
• and
• a circular polarizer that overlaps the array of organic light-emitting diode pixels, wherein the circular polarizer includes a linear polarizer formed from a plurality of polarizing fibers that guide light from the array of organic light-emitting diode pixels towards a display output surface.

An electronic device comprising:

• a display panel that displays an image;
• and
• fibers that overlap a corner portion of the display panel, wherein the fibers receive a portion of the image from the display panel and present the portion of the image at an output surface of the fibers that has compound curvature in a rounded corner that is bent downwards.

An electronic device comprising:

• a display panel that displays an image;
• and
• fibers that overlap a corner portion of the display panel, wherein the fibers receive a portion of the image from the display panel and present the portion of the image at an output surface of the fibers that has compound curvature in a corner that is bent.

An electronic device comprising:

• a display panel that emits light;
• four discrete fiber bundles, wherein each fiber bundle overlaps a respective corner portion of the display panel and wherein the display panel has edge portions that are not covered by any fibers.
