Abstract: An electronic device display may have pixels formed from crystalline semiconductor light-emitting diode dies, organic light-emitting diodes, or other pixel structures. The pixels may be formed on a display panel substrate. A display panel may extend continuously across the display or multiple display panels may be tiled in two dimensions to cover a larger display area. Interconnect substrates may have outwardly facing contacts that are electrically shorted to corresponding inwardly facing contacts such as inwardly facing metal pillars associated with the display panels. The interconnect substrates may be supported by glass layers. Integrated circuits may be embedded in the display panels and/or in the interconnect substrates. A display may have an active area with pixels that includes non-spline pixels in a non-spline display portion located above a straight edge of the display and spline pixel in a spline display portion located above a curved edge of the display.

Abstract: An electronic device may have a display such as an organic light-emitting diode display. The organic light-emitting diode display may have an array of organic light-emitting diode pixels that each have organic light-emitting diode layers interposed between a cathode and an anode. To improve off-axis luminance and luminance uniformity, the display may include green pixels with emission spectra having a narrow full width at half maximum, the display may include a reflective layer that is formed separately from a transparent anode, and/or the display may include a diffusive layer. The diffusive layer may be embedded in one or more encapsulation layers for the display. The diffusive layer may be a diffusive color filter.

Abstract: An electronic device is provided with a display and a light sensor that receives light that passes through the display. The display includes features that increase the amount of light that passes through the display. The features may be translucency enhancement features that allow light to pass directly through the display onto a light sensor mounted behind the display or may include a light-guiding layer that guides light through the display onto a light sensor mounted along an edge of the display. The translucency enhancement features may be formed in a reflector layer or an electrode layer for the display. The translucency enhancement features may include microperforations in a reflector layer of the display, a light-filtering reflector layer of the display, or a reflector layer of the display that passes a portion of the light and reflects an additional portion of the light.

The electrical components may be mounted to a support structure such as a flexible printed circuit. The flexible printed circuit may have a mesh shape formed from an array of openings. Serpentine flexible printed circuit segments may extend between the openings. The electrical components may be light-emitting diodes or other electrical devices. Polymer with light-scattering particles or other materials may cover the electrical components. The flexible printed circuit may be laminated between fabric layers or other layers of material in the fabric-based item.

Abstract: Systems, methods, and devices are provided to reduce a likelihood of image burn-in on an electronic display. Such an electronic device may include image processing circuitry and an electronic display. The image processing circuitry may receive image data and analyze the image data for risk of image burn-in and, based at least in part on the analysis of the image data, reduce a risk of image burn-in at least in part by reducing a local maximum pixel luminance value in at least one of a plurality of regions of the image data over time or by reducing a dynamic range headroom of the image data. The electronic display may display the image data with a reduced risk of image burn-in on the pixels of the electronic display.

Abstract: A display may have an array of organic light-emitting diodes that form an active area on a flexible substrate. Metal traces may extend between the active area and an inactive area of the flexible substrate. Display driver circuitry such as a display driver integrated circuit may be coupled to the inactive area. The metal traces may extend across a bend region in the flexible substrate. The flexible substrate may be bent in the bend region. The flexible substrate may be made of a thin flexible material to reduce metal trace bending stress. A coating layer in the bend region may be provided with an enhanced elasticity to allow its thickness to be reduced. The flexible substrate may be bent on itself and secured within an electronic device without using a mandrel.

Abstract: An electronic device such as a voice-controlled speaker device may have a housing characterized by a vertical longitudinal axis. A flexible substrate such as a flexible mesh substrate with component support regions coupled by flexible segments may be wrapped around the housing and the vertical axis. The housing may have surface regions with compound curvature. The flexible substrate may conform to the regions with compound curvature. A fabric spacer layer may be interposed between the flexible substrate and the housing. Electrical components such as input-output devices may be mounted to the component support regions. A display may be formed from an array of light-emitting devices that are mounted on respective component support regions. Light from the light-emitting devices may pass through the fabric spacer layer toward the housing and back out away from the housing. An outer fabric layer may cover the mesh.
