Patent number: 11860394Abstract: An electronic device may have a display overlapped by an image transport layer such as a coherent fiber bundle or layer of Anderson localization material. The image transport layer may have an input surface that receives an image from the display and a corresponding output surface to which the image is transported. The input surface and output surface may have different shapes. During fabrication of the image transport layer, molding techniques, grinding and polishing techniques, and other processes may be used to deform the image transport layer and the shape of the output surface. To help reduce ambient light reflections and stray light, light-absorbing structures may be incorporated into the image transport layer and other structures overlapping the display.Type: GrantFiled: July 21, 2020Date of Patent: January 2, 2024Assignee: Apple Inc.Inventors: Yi Qiao, Jean-Pierre S. Guillou, Michael J. Brown, Paul C. Kelley, Tyler R. Kakuda, Ying-Chih Wang, Salman Karbasi

Patent number: 11817025Abstract: An electronic device may have pixels. The pixels may form one or more displays. The displays may be flexible organic light-emitting diode displays or other displays. The electronic device may have first and second display layers that face away from each other and display images in different directions. Image transport layers may overlap the display layers and may have curved edges that overlap a sidewall portion of the electronic device. Image transport layers receive images at input surfaces and transport the received images to corresponding output surfaces. Image transport layers may be provided with hemispherical shapes and other shapes having output surfaces of compound curvature. A folding device may have first and second displays that are overlapped by respective first and second image transport layers that join over a hinge to block the hinge from view. A wristwatch device may have links or other structures with an image transport layer.Type: GrantFiled: November 13, 2019Date of Patent: November 14, 2023Assignee: Apple Inc.Inventors: Ying-Chih Wang, Michael J.

Patent number: 11810534Abstract: 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.Type: GrantFiled: September 10, 2019Date of Patent: November 7, 2023Assignee: Apple Inc.Inventors: Yi Qiao, Jean-Pierre S. Guillou, Yingying Tang, Michael J. Brown, Paul C. Kelley, Tyler R. Kakuda, Hao Dong, Ying-Chih Wang, Chaohao Wang, Shaorui Yang, Wei H. Yao

Patent number: 11747553Abstract: An electronic device may have a display overlapped by an image transport layer such as a coherent fiber bundle or layer of Anderson localization material. The image transport layer may have an input surface that receives an image from the display and a corresponding output surface to which the image is transported. The input surface and output surface may have different shapes. During fabrication of the image transport layer, molding techniques, grinding and polishing techniques, and other processes may be used to deform the image transport layer and the shape of the output surface. To accommodate differences in material deformation and other factors that vary as a function of position across the image transport layer, the image transport layer may be formed from canes of fibers or other material with one or more properties that vary as a function of position.Type: GrantFiled: September 18, 2020Date of Patent: September 5, 2023Assignee: Apple Inc.Inventors: Tyler R.

Patent number: 11650368Abstract: An electronic device may have a display that displays an image. The image may be viewed through a display cover layer that overlaps the display. The display cover layer may include an optical coupling layer such as a coherent fiber bundle. A pixel expansion layer such as a diffractive layer may be incorporated between the optical coupling layer and a protective layer. The diffractive layer may create duplicate pixels to occupy otherwise non-light-emitting areas on the output surface of the display cover layer. The diffractive layer may also create duplicate pixels that overlap adjacent pixels to allow for brightness averaging. An adhesive layer or the protective layer may be used to form diffractive elements for the diffractive layer. An adhesive layer having a high index of refraction may be interposed between the optical coupling layer and the display panel to mitigate undesired reflections of ambient light.Type: GrantFiled: October 15, 2020Date of Patent: May 16, 2023Assignee: Apple Inc.Inventors: Yi Qiao, David A.

An image transport layer may be formed from a coherent fiber bundle or Anderson localization material. The image transport layer may overlap the pixels and may have an input surface that receives the image from the pixels and a corresponding output surface on which the received image is viewable.

Patent number: 11402869Abstract: An electronic device may have a housing with a display. The display may be overlapped by an image transport layer such as a coherent fiber bundle or layer of Anderson localization material. The image transport layer may have an input surface that receives an image from the display and a corresponding output surface to which the image is transported. The input surface and output surface may have different shapes. During fabrication of the image transport layer, molding techniques, grinding and polishing techniques, and other processes are used to deform the image transport layer and the shape of the output surface. The area of peripheral portions of the output surface may expand relative to central portions. Optical uniformity across the output surface can be enhanced by maintaining uniformity in fiber core diameters and other attributes of the image transport layer across deformed and undeformed portions of the output surface.Type: GrantFiled: July 17, 2020Date of Patent: August 2, 2022Assignee: Apple Inc.Inventors: Elizabeth C.

Patent number: 11364697Abstract: An electronic device may have a housing with a display. A protective display cover layer for the display may have an image transport layer such as a fiber optic plate. The fiber optic plate may be formed from a bundle of fibers. The fibers may be formed using fiber extruding equipment. Each fiber may have a core covered with a cladding, a stray light absorbing layer, and binder material. The fibers may be deformed in a heated chamber by pressing inwardly with a die that has a recess, causing the fibers to bulge into the recess. A cutter can be used to cut off a layer of the deformed fibers. This layer may be machined and polished to form the fiber optic plate.Type: GrantFiled: February 27, 2020Date of Patent: June 21, 2022Assignee: Apple Inc.Inventor: Paul C. Kelley
