Abstract: A touch sensor panel can include a plurality of drive lines crossing a plurality of sense lines, forming an array. The plurality of drives lines and the plurality of sense lines can be formed by interconnecting sections of at least one conductive material with a plurality of bridges. The geometry and size of one or more of the plurality of bridges and the arrangement of the sections can be altered to reduce the overall resistance of a section, improve optical uniformity, and/or increase conductance. Additionally, the sensitivity to and differentiation between touch, hover, or proximity can be enhanced based on the number of bridges and the number of hot spots.

Abstract: Pixels in an organic light-emitting diode (OLED) display may be microcavity OLED pixels having optical cavities. The optical cavities may be defined by a partially transparent cathode layer and a reflective anode structure. The anode of the pixels may include both the reflective anode structure and a supplemental anode that is transparent and that is used to tune the thickness of the optical cavity for each pixel. Organic light-emitting diode layers may be formed over the pixels and may have a uniform thickness in each pixel in the display. Pixels may have a conductive spacer between a transparent anode portion and a reflective anode portion, without an intervening dielectric layer. The conductive spacer may be formed from a material such as titanium nitride that is compatible with both anode portions. The transparent anode portions may have varying thicknesses to control the thickness of the optical cavities of the pixels.

Abstract: Display layers and touch sensor layers may be overlapped by enclosure walls in an electronic device. The electronic device may have a front wall and opposing rear wall and curved sidewalls. The front wall and the curved sidewalls may be formed from a glass layer or other transparent member. A touch sensor layer and display layer may extend under the glass layer with curved sidewalls. A touch sensor layer may also extend under the opposing rear wall. A foldable electronic device may have a flexible transparent wall portion that joins planar transparent walls. Components may be interposed between the transparent planar walls and opaque walls. Display and touch layers may be overlapped by the transparent walls and the transparent flexible wall portion. Touch sensor structures may also be overlapped by the opaque walls.

Abstract: An electronic device may have a housing. Input-output devices may be mounted in the housing. The input-output devices may include a display with an array of pixels configured to display images for a user. The electronic device may have an optical component formed under a transparent region in the housing. The transparent region may be associated with an opening in an opaque masking layer in an inactive area of the display or other portion of the electronic device. A diffuser may be formed between the optical component and the transparent region. The diffuser may have a polymer layer with embedded thin-film interference filter flakes configured to scatter light and to exhibit desired reflection and transmission spectral.

Abstract: An organic light-emitting diode (OLED) display may have an array of organic light-emitting diode pixels that each have OLED layers interposed between a cathode and an anode. Voltage may be applied to the anode of each pixel to control the magnitude of emitted light. The conductivity of the OLED layers may allow leakage current to pass between neighboring anodes in the display. To reduce leakage current and the accompanying cross-talk in a display, the pixel definition layer may disrupt continuity of the OLED layers. The pixel definition layer may have an undercut to disrupt continuity of some but not all of the OLED layers. The undercut may be defined by three discrete portions of the pixel definition layer. The undercut may result in a void that is interposed between different portions of the OLED layers to break a leakage path formed by the OLED layers.

Abstract: An electronic device with a force sensing device is disclosed. The electronic device comprises a user input surface defining an exterior surface of the electronic device, a first capacitive sensing element, and a second capacitive sensing element capacitively coupled to the first capacitive sensing element. The electronic device also comprises a first spacing layer between the first and second capacitive sensing elements, and a second spacing layer between the first and second capacitive sensing elements. The first and second spacing layers have different compositions. The electronic device also comprises sensing circuitry coupled to the first and second capacitive sensing elements configured to determine an amount of applied force on the user input surface. The first spacing layer is configured to collapse if the applied force is below a force threshold, and the second spacing layer is configured to collapse if the applied force is above the force threshold.

Abstract: An organic light-emitting diode (OLED) display may have an array of organic light-emitting diode pixels that each have OLED layers interposed between a cathode and an anode. Voltage may be applied to the anode of each pixel to control the magnitude of emitted light. The conductivity of the OLED layers may allow leakage current to pass between neighboring anodes in the display. To reduce leakage current and the accompanying cross-talk in a display, the pixel definition layer may disrupt continuity of the OLED layers. The pixel definition layer may have a steep sidewall, a sidewall with an undercut, or a sidewall surface with a plurality of curves to disrupt continuity of the OLED layers. A control gate that is coupled to a bias voltage and covered by gate dielectric may be used to form an organic thin-film transistor that shuts the leakage current channel between adjacent anodes on the display.

Abstract: Processes for manufacturing touch sensors with one or more guard traces to reduce the effect of moisture damage are provided. One example process can include forming one or more guard traces between an edge of the touch sensor and the metal traces that route the drive and sense lines to bond pads. The one or more guard traces can be uncoupled from the drive lines and sense lines to protect the inner metal traces from moisture damage. In some examples, ends of the one or more guard traces can be coupled to ground by copper. In other examples, ends of the one or more guard traces can be coupled to ground by indium tin oxide or the one or more guard traces can be coupled to ground by a strip of indium tin oxide. In yet other examples, the guard trace can be floating (e.g., not coupled to ground).
