    Abstract: 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.

    Abstract: An electronic device may be provided with a display. The display may have an array of pixels that form an active area and may have an inactive area that runs along an edge of the active area. An opaque layer may be formed on an inner surface of a display cover layer in the inactive area of the display or may be formed on another transparent layer in the electronic device. An ambient light sensor window may be formed from the opening and may be aligned with color ambient light sensor. The ambient light sensor may have an integrated circuit with photodetectors. Ambient light passing through the ambient light sensor window may be diffused by a light diffuser having one or more light-diffusing layers. Diffused ambient light may be collimated using a light collimator having one or more light-collimating layers such as layers with inwardly facing protrusions.

    Abstract: A polarizer integrated with conductive material and a process for forming a polarizer integrated with conductive material are disclosed. A polarizer can be integrated with conductive material to form a portion of a touch sensor panel. In one example, a layer of conductive film forming either the row or column traces can be patterned on a surface of a substrate in the polarizer. In another example, the layer of conductive film can be patterned on a viewing angle compensation film of the polarizer. One or more of the polarizer's polarizing layer, protective substrates or viewing angle compensation film can act as a dielectric between the conductive material forming the rows and column traces in the stack-up. As a result, the clear polymer spacer acting as a dielectric in touch panels can be removed, reducing the thickness of the touch screen stack-up.

    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: An optically transparent force sensor element includes multi-layer electrodes of two materials having different gauge factors to increase sensitivity of measured force magnitude. A passivation layer is positioned between the electrode layers in each element. One gauge factor may be positive while the other gauge factor may be negative.

    Abstract: Processes for reducing physical contact to sheets of base film in roll-to-roll processing of touch sensors are disclosed. In one example, the process includes the use of rollers having rings circumferentially extending away from the roller and operable to contact the sheets of base film. The rings can be configured to contact portions of the sheet of base film away from touch sensor areas of the base film. The rings can further be configured to prevent the sheets of base film from contacting a shaft of the rollers. In another example, a reduced strength vacuum seal can be formed between a photo mask and the sheet of base film to reduce the amount of force applied to a passivation layer of the sheet of base film.
