Abstract: A display may have a backlight unit with a row of light-emitting diodes that emit light into the edge of a light guide plate. The light guide plate may have opposing upper and lower surfaces. The upper surface of the light guide plate may have ridges and the lower surface of the light guide plate may have bumps. The edge of the light guide plate may have light mixing structures. The light mixing structures may include edge surfaces that refract light at a high angle. The high angle light may then be reflected by a reflective surface so that the light propagates down the light guide plate. Some light may pass through the light mixing structures and propagate down the light guide plate without being reflected by the reflective surface. This arrangement may reduce the mixing distance of the backlight unit.

Abstract: An electronic device may have a display with pixels configured to display an image. The pixels may be overlapped by a cover layer. The display may have peripheral edges with curved cross-sectional profiles. An inactive area in the display may be formed along a peripheral edge of the display or may be surrounded by the pixels. Electrical components such as optical components may be located in the inactive area. An image transport layer may be formed from a coherent fiber bundle or Anderson localization material. The image transport layer may overlap the pixels, may have an opening that overlaps portions of the inactive area, may have an output surface that overlap portions of the inactive area, and/or may convey light associated with optical components in the electronic device.

Abstract: An electronic device may have a display with pixels configured to display an image. 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. The image transport layer may form an exterior surface of the electronic device or may be overlapped by a transparent cover layer. Various methods such as swelling, piping, and slumping may be used to process fibers and form image transport layers. A fiber bundle that is used to form an image transport layer may include fibers that have varying properties.

Abstract: 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.

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.

Abstract: A display may have a backlight unit with a row of light-emitting diodes that emit light into the edge of a light guide plate. The light guide plate may have opposing upper and lower surfaces. Backlight may be extracted from the light guide plate using an array of bumps on the lower surface and ridges on the upper surface. Ridge density may vary as a function of location across the display. Some of the ridges may be terminated along a meandering border between regions of differing ridge density. Ridge length and endpoint location can be dithered along borders between regions and ridge widths and thicknesses may be tapered down towards the endpoints. Ridges may be patterned to reduce the density of the ridges immediately adjacent the light-emitting diodes and thereby avoid over-extraction of the light at the light-emitting diodes.

Abstract: A display may have a backlight unit with a row of light-emitting diodes that emit light into the edge of a light guide layer. The light guide layer may have opposing upper and lower surfaces. The upper surface of the light guide layer may have ridges and the lower surface of the light guide layer may have bumps. The edge of the light guide layer may have light mixing structures. The light mixing structures may include an alternating pattern of protrusions with different shapes. For example, triangular protrusions of a first size may be patterned with triangular protrusions of a second size. The light mixing structures may reduce the mixing distance of the backlight unit.

Abstract translation: 显示器可以具有背光单元，其具有发射到导光板的边缘的光的发光二极管排。 导光板可以具有相对的上表面和下表面。 可以使用下表面上的凸起阵列和上表面上的脊来从导光板提取背光。 脊密度可能随着显示器上的位置而变化。 一些脊可以沿着不同脊密度的区域之间的曲折边界终止。 脊长度和端点位置可以沿着区域之间的边界抖动，并且脊宽度和厚度可以朝着端点逐渐变细。 可以对脊进行图案化以降低与发光二极管紧邻的脊的密度，从而避免在发光二极管处的光的过度提取。
