Abstract: An electronic device is disclosed which includes a conductive layer for providing haptic feedback at an input surface of the electronic device. The conductive layer includes conductive particles within an organic compound, such as an epoxy. When the conductive layer is activated it may provide frictional or other tactile feedback at the input surface.

Abstract: Display panels and methods of manufacture are described for down converting a peak emission wavelength of a pump LED within a subpixel with a quantum dot layer. In some embodiments, pump LEDs with a peak emission wavelength below 500 nm, such as between 340 nm and 420 nm are used. QD layers in accordance with embodiments can be integrated into a variety of display panel structures including a wavelength conversion cover arrangement, QD patch arrangement, or QD layers patterned on the display substrate.

Abstract: An electronic device includes an electrostatic conductive layer for providing haptic feedback at an input surface of the electronic device. The electrostatic conductive layer is included in a cover assembly positioned over a display. The cover assembly includes a cover sheet, a touch sensor, and the electrostatic conductive layer. The electrostatic conductive layer is driven by an electric field, which electric field is produced by the touch sensor. When the electrostatic conductive layer is activated, it may provide frictional or other tactile feedback at the input surface.

Abstract: A transparent force sensor for detecting an applied force on a surface of a device. The transparent force sensor includes a transparent force-sensitive film having an array of strain-relief features oriented along a first direction. The transparent force-sensitive film is formed from a transparent piezoelectric material that exhibits a substantially reduced net charge when strained along a primary direction. The force sensor also includes a display element disposed on one side of the transparent force-sensitive film.

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: An optical force sensor that may compensate for environmental effects, including, for example, variations in temperature of the device or the surroundings. In some examples, two force-sensitive layers are separated by a compliant layer. The relative electrical response of the two force-sensitive layers may be used to compute an estimate of the force of a touch that reduces the effect of variations in temperature. In some examples, piezoelectric films having anisotropic strain properties are used to reduce the effects of temperature.
