An electronic device may have a display overlapped by a cover layer. Portions of the surface of the display and cover layer may have curved profiles. The display may include a flexible substrate and may have bent edge portions protruding from a central region. Gaps may be formed between regions of pixels on a common substrate or between separate display panels. An image transport layer formed from a coherent fiber bundle or a layer of Anderson localization material configured to exhibit two-dimensional transverse Anderson localization of light may have an input surface that receives an image from adjacent display pixels and an output surface on which the image is displayed. The output surface may have a curved profile and may exhibit compound curvature. The input surface may have a profile with curved portions or other shapes. Image transport layers can be used to cover gaps between sets of pixels.

A method of forming a micro-lensed fiber optic plate. The method includes obtaining a fiber optic plate that has a plurality of fibers arranged in parallel. A first end of a fiber of the plurality of fibers can have a first numerical aperture. The fiber of the plurality of fibers includes a core material running along a length of the fiber that is circumscribed by a layer of cladding material. The method also includes creating a lensed surface at a second end of the fiber of the plurality of fibers. The second end is opposite the first end. The lensed surface of the fiber of the plurality of fibers can have a second numerical aperture that is different from the first numerical aperture.

An electronic device is provided which can be worn on the body or implanted into the body, such as in the form of a pulse watch and/or a smartwatch and/or an implant. The electronic device includes a photoplethysmographic measuring device. A transmitter diode and a receiver diode are arranged under a window made of glass or glass ceramics. The window is implemented as a compression glass seal and/or as a fiber-optic plate.

A head mounted display (HMD) includes a field curvature corrected (FC) display to mitigate field curvature in an image that is output to a user's eyes. The FC display includes elements that generate the image light and elements to mitigate field curvature from the image light. The FC display may include a display panel with lenses, a display panel with a reflective polarizer and reflective surface, or other optical elements. The FC display may include a pancake lens configuration including a polarized display with a quarter wave plate, a reflective mirror, and a polarization reflective mirror.

There is provided a display device that is able to display a favorable image. This display device includes: a display section including a display surface that emits image light; a light guide member in which a plurality of optical fibers each including a core part and a cladding part are bundled and integrated, in which the core part guides the image light from an incident surface facing the display surface to an emission surface positioned opposite to the incident surface, and the cladding part surrounds the core part; and a first optical member provided on side opposite to the display section as viewed from the light guide member, in which the first optical member converts light distribution of the image light emitted from the emission surface.

An electronic device includes a housing and a display. The housing defines an interior cavity and includes an optically-transmissive housing component. The display is disposed in the interior cavity and is viewable through the optically-transmissive housing component. An optoelectronic component is disposed in the interior cavity. An optical fiber extends between a first end positioned adjacent the optoelectronic component and a second end positioned adjacent the optically-transmissive housing component. The optical fiber defines a non-linear optical path between the first end and the second end. At least a portion of the optical fiber is laterally offset from a lateral edge of the display.

Disclosed are high-density energy directing devices and systems thereof for two-dimensional, stereoscopic, light field and holographic head-mounted displays. In general, the head-mounted display system includes one or more energy devices and one or more energy relay elements, each energy relay element having a first surface and a second surface. The first surface is disposed in energy propagation paths of the one or more energy devices and the second surface of each of the one or more energy relay elements is arranged to form a singular seamless energy surface. A separation between edges of any two adjacent second surfaces is less than a minimum perceptible contour as defined by the visual acuity of a human eye having better than 20/40 vision at a distance from the singular seamless energy surface, the distance being greater than the lesser of: half of a height of the singular seamless energy surface, or half of a width of the singular seamless energy surface.
