Abstract
A display may have an array of display pixels that generate an image. A coherent fiber bundle may be mounted on the display pixels. The coherent fiber bundle may have a first surface that is adjacent to the display pixels and a second surface that is visible to a viewer. The coherent fiber bundle may contain fibers that carry light from the first surface to the second surface. The second surface may be planar or may have a central planar region and curved edge regions that run along opposing sides of the central planar region. The fibers may have cross-sectional surface areas with a first aspect ratio on the first surface and a second aspect ratio that is greater than the first aspect ratio on the second surface.
Claims18
An electronic device, comprising:
- an array of pixels having a first width;
- and
- a light guiding structure having first and second surfaces, wherein the light guiding structure is configured to guide light from the array of pixels from the first surface to the second surface, the second surface has a planar central portion and has curved edge portions, the second surface has a second width that is greater than the first width, the light guiding structure comprises a fiber bundle having a plurality of fibers that guide the light to the curved edge portions and to at least a portion of the planar central portion, and each of the curved edge portions comprises multiple fibers of the plurality of fibers that form a single curved profile.
An electronic device, comprising:
- an array of pixels having a first width;
- and
- a light guiding structure having first and second surfaces, wherein the light guiding structure is configured to guide light from the array of pixels from the first surface to the second surface, wherein the second surface has a planar central portion and has curved edge portions, wherein the second surface has a second width that is greater than the first width, wherein the light guiding structure comprises a fiber bundle having a plurality of fibers that guide the light to the curved edge portions and to at least a portion of the planar central portion, and wherein at least one of the fibers of the plurality of fibers that guide the light to the curved edge portions has a first portion that bends in a first direction and a second portion that bends in a second direction that is different from the first direction.
An electronic device having exterior surfaces and a periphery, the electronic device comprising:
- a sidewall structure that extends around the periphery to form at least one of the exterior surfaces;
- a display that includes an array of pixels and a light guiding structure having first and second surfaces, wherein the light guiding structure guides light from the array of pixels from the first surface to the second surface and has a curved portion and a planar portion, the curved portion overlaps the sidewall structure, and the curved portion has a single curved profile over the entire sidewall structure.
