摘要： Touch sensor panels typically include a plurality of layers that can be stacked on top of each other. When the touch sensor panel is used in a bright environment, incident light can hit the interfaces between those layers of the stackup having mismatched refractive indices and can reflect off those interfaces. The light reflected from those interfaces can give rise to the appearance of fringes on the touch sensor panel, which can be visually distracting. In order to reduce the appearance of these fringes, embodiments of the disclosure are directed to the addition of an index matching passivation layer between a conductive layer of traces and an adhesive layer in the touch sensor panel stackup.

摘要： 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.

摘要： A touch sensor panel can include a silver nanowire touch electrodes formed in a silver nanowire layer on the substrate. In some examples, the touch sensor panel can include one or more anticorrosion layers to protect silver nanowire layer from ionization. In some examples, the silver nanowires include electrochemically stable outer shells that protect the silver nanowires from ionization. Additionally or alternatively, the touch sensor panel can including one or more anti-static layers to protect against electrostatic discharge (ESD). Additionally or alternatively, one or more anticorrosion layers and/or one or more antistatic layers can be formed with a passivation layer therebetween. The passivation layer, one or more anticorrosion layers and/or one or more antistatic layers can then be laminated to the silver nanowire layer to prevent corrosion and/or ESD events in the silver nanowire layer during the fabrication of the touch sensor panel.

摘要： A display may have an active area in which pixels display images through a transparent display layer. An opaque masking material may be formed in an inactive border area adjacent to the active area. The opaque masking layer may include particles such as carbon black particles to provide the opaque masking layer with a dark appearance. The color of the opaque masking layer may be adjusted by incorporating additional particles such as titanium oxide particles. Particle size for the carbon black particles and the index of refraction of the opaque masking layer may be adjusted to reduce reflectance in the inactive border area. A transparent conductive layer may be supported by the transparent display layer. Index-of-refraction matching layers may be interposed between the transparent conductive layer and the transparent display layer. The opaque masking layer may be interposed between the matching layers in the inactive border area.

摘要： 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.
