Abstract: This disclosure generally provides an input device that includes a multi-layered capacitive sensor which includes a first layer disposed over a second layer that contains a plurality of sensor electrodes coupled to respective traces. The first and second layers form a capacitive sensing stack where the first layer is between the second layer and a touch surface for interacting with the input object. The first and second layers may be disposed on either the same substrate or different substrates in the stack. In one embodiment, the first layer includes electrically floating electrodes and at least one guard electrode. These components may align with respective components in the second layer. For example, the electrically floating electrodes in the first layer may at least partially cover the sensor electrodes in the second layer.

Abstract: A system and method for an electronic device for imaging a biometric object having structural features of interest is disclosed. The electronic device includes a display including rows of pixel elements, the rows of pixel elements being parallel a first primary direction along a first axis and an optical sensor mounted underneath the display, the optical sensor being parallel to a second primary direction along a second axis. The second axis is rotated at an angle relative the first axis to adjust a moiré pattern outside of a frequency range of the features of interest.

Abstract: An input device having a plurality of low-visibility sensor electrodes and method for fabricating the same are provided. In one example, an input device includes a display device having an array of pixels and a plurality of sensor electrodes disposed on a viewing side of the display device. At least a first sensor electrode of the plurality of sensor electrodes includes a plurality of spaced apart conductive traces forming a conductive mesh, wherein mesh having a first periodicity defined by intersections of the conductive traces forming the mesh. A terminal portion of one of the conductive traces terminates at an edge of the first sensor electrode and has an attached light occluding element. The attached light occluding element is disposed over a subpixel having the same color as a subpixel which an intersecting trace would lay over when the intersection occurs in an interior region of the sensor electrode.
