Abstract: A touch sensor panel including artwork formed on the touch sensor panel is disclosed. The touch sensor panel stackup can include a substrate, one or more underlying layers, one or more patterned transparent conductive layers, a passivation layer, artwork, and an adhesive layer. The artwork on the touch sensor panel can be formed by aligning to the touch sensor pattern or alignment marks. In some examples, the artwork can be formed on a discrete touch sensor panel, and the discrete touch sensor panel can be bonded to a cover glass or cover material. In some examples, the touch sensor panel can be a Dual-sided Indium Tin Oxide (DITO) stackup. In some examples, the drive lines and the sense lines of the touch sensor panel can be formed on separate substrates, and the substrates can be bonded together using an adhesive.

Abstract: Processes for fabricating compact touch sensors for touch sensitive devices are disclosed. A process can include providing a touch sensor structure having a substrate, a first layer disposed on the substrate, and a second layer disposed on the first layer. The second layer can have an ablation fluence value that is lower than an ablation fluence value of the first layer. The process can include patterning the second layer with a laser emitting energy having a fluence value greater than or equal to the ablation fluence value of the second layer and less than the ablation fluence value of the first layer. The process can further include etching at least a portion of the first layer that was exposed during the patterning of the second layer. At least a portion of the second layer can then be removed by etching or laser ablation.

Abstract: An electronic device includes one or more transparent strain sensors configured to detect strain based on an amount of force applied to the electronic device, a component in the electronic device, and/or an input surface of the electronic device. The one or more transparent strain sensors may be included in or positioned below an input surface that is configured to receive touch inputs from a user. The area below the input surface can be visible to a user when the user is viewing the input surface. The one or more transparent strain sensors are formed with a nanostructure, including a nanomesh or nanowires.

Abstract: To extract light from a light-emitting diode (and thereby improve efficiency of the display), a microlens stack may be formed over the light-emitting diode. The microlens stack may include an array of microlenses that is covered by an additional single microlens. Having stacked microlenses in this way increases lens power without increasing the thickness of the display. The array of microlenses may be formed from an inorganic material whereas the additional single microlens may be formed from an organic material. The additional single microlens may conform to the upper surfaces of the array of microlenses. An additional low-index layer may be interposed between the light-emitting diode and the array of microlenses. A diffusive layer may be formed around the light-emitting diode to capture light emitted from the light-emitting diode sidewalls.

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: 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.
