  • Publication number: 20190221157
    Abstract: The present disclosure relates generally systems and methods for controlling current provided to display devices. A method for controlling the current may include receiving drive current values associated with subpixels in a display and receiving information that corresponds to an application type being rendered on the display and/or an indication of image data being rendered on the display. The method may then include reducing at least some of the drive current values based at least in part on the application type. Alternatively, the method may include reducing the at least a portion of the image data corresponding to the at least some of the drive current values has substantially similar luminance and color values. The method may then include supplying the subpixels with drive currents that correspond to the drive current values.

  • Publication number: 20190212603
    Abstract: An electronic device may be provided with a display having a thin-film transistor layer. One or more holes in the thin-film transistor layer may be used to form pathways from display circuitry to other circuitry underneath the display. One or more conductive bridges may pass through holes in the thin-film transistor layer and may have one end that couples to the display circuitry and a second end that couples to a printed circuit underneath the display. These conductive bridges may be formed from wire bonding. Wire bond connections may be encapsulated with potting material to improve the reliability of the wire bond and increase the resiliency of the display. Display signal lines may be routed through holes in a thin-film transistor layer to run along a backside of the display thereby reducing the need for space in the border region for display circuitry.

  • Patent number: 10345905
    Abstract: An electronic device may be provided with a housing in which display structures are mounted. Additional input-output devices such as a track pad may also be mounted in the housing. These input-output devices may include components such as touch sensors and force sensors for gathering input from a user. The display structures may include a display such as a flexible organic light-emitting diode display or a liquid crystal display that can present visual information to the user. To provide the user with tactile output, an output device such as a display or track pad may be provided with electroactive polymer structures, electromagnetic actuators, and other tactile output devices. The tactile output devices may provide protrusions, indentations, selectively stiffened and softened areas, and other tactile output for a user.

  • Publication number: 20190080670
    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.

  • Patent number: 10199323
    Abstract: An item may have a flexible support structure and may include a flexible component. The flexible component may have electrical components mounted on component mounting regions in a flexible circuit substrate. The component mounting regions may be interconnected by serpentine interconnect paths or other flexible interconnect paths. The flexible circuit substrate and component mounting regions may extend along a longitudinal axis of the flexible component or may form a two-dimensional array. Two-dimensional mesh-shaped flexible circuit substrates may be used in forming displays. The mesh-shaped flexible circuit substrates may be auxetic substrates that widen when stretched (e.g., structures with a negative Poisson's ratio that become thicker perpendicular to applied force when stretched) and that therefore reduce image distortion. Temporary tethers may help hold flexible circuit substrates together until intentionally broken following assembly of a flexible component into the flexible support structure.

  • Patent number: 10198040
    Abstract: An electronic device may have a flexible portion that allows the device to be folded. The device may have a flexible display. The flexible display may have a flexible display layer, a cover layer, a touch sensor interposed between the flexible display layer and the cover layer, a support layer, and a polarizer layer. The polarizer layer may be interposed between the touch sensor and the flexible display or between the touch sensor and the cover layer. The touch sensor may include optically clear adhesive that is flexible and facilitates bending of the display. The optically clear adhesive may include additives such as water vapor penetration reducing additive, anticorrosion additive, ultraviolet-light blocking additive, and index-of-refraction adjustment additive. The support layer may be formed from shape memory alloy or amorphous metal and may have openings to facilitate bending.

  • Patent number: 10181504
    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 bent region in the flexible substrate. A coating layer in the bent region may serve as a neutral stress plane adjustment layer. Metal traces may have meandering shapes such as zigzag shapes to reduce stress when bending. Adjacent traces may be shorted together to provide redundancy. Multiple layers of traces may be provided. Inorganic passivation layer coatings on the metal traces may help protect the metal traces.

    Abstract: A display may have an array of organic light-emitting diodes that form an active area on a flexible substrate. Display driver circuitry such as a display driver integrated circuit may be coupled to an inactive area of the flexible substrate. Metal traces may extend across a bent region of the flexible substrate between the active area and inactive area. Metal traces may have zigzag shapes to reduce stress when bending. Adjacent pairs of parallel segments in the metal traces may be shorted together by a bridging segment that extends perpendicular to the two parallel segments. The bridging segment may be offset from corners to avoid clusters of stress zones in the metal trace. Neutral plane adjustment layers in the bent region may include a metal layer to help counteract the bending force of the flexible substrate and the relaxation of an upper polymer coating.

  • Patent number: 10163388
    Abstract: An electronic device may be provided with a display. A content generator may generate frames of image data to be displayed on the display. The display may have an array of pixels that emit light to display images. The pixels may contain light-emitting devices such as organic light-emitting diodes, quantum dot light-emitting diodes, and light-emitting diodes formed from discrete semiconductor dies. As a result of aging, the light producing capabilities of the light-emitting devices may degrade over time. The electronic device may have a temperature sensor that gathers temperature measurements. A pixel luminance degradation compensator may apply compensation factors to uncorrected pixel luminance values associated with the frames of image data to produce corresponding corrected pixel luminance values for the display. The compensation factors may be based on aging history information such as pixel luminance history and temperature measurements.
