Abstract: A touch sensor panel includes a first set of touch electrodes configured to operate as drive lines and that are disposed in a first layer of the touch sensor panel. The touch sensor panel also includes a second set of touch electrodes configured to operate as sense lines and that are disposed in a second layer of the touch sensor panel, different than the first layer of the touch sensor panel, such that one or more mutual capacitance touch nodes are formed by the first set of touch electrodes and the second set of touch electrodes. The touch sensor panel also includes a third set of touch electrodes configured to operate as self-capacitance electrodes and that are disposed in the first layer or the second layer of the touch sensor panel.

Abstract: Touch sensor panel configurations and methods for improving touch sensitivity of some or all of the electrodes or portions of the touch sensor panel are disclosed. The touch sensor panel configurations can allow increased speed at which the panel can operate. In some examples, the performance of a given touch electrode can differ from the performance of another touch electrode due to differences in capacitance and/or resistance. The performance of the touch sensor panel can be limited by the touch electrode with the lowest performance relative to the other touch electrodes. The configurations and methods can increase the performance of the touch sensor panel by minimizing the capacitive coupling and/or resistance of touch electrodes. Examples of the disclosure can provide configurations of touch sensor panels and methods for improving optical uniformity of the panel.

Abstract: In some examples, a touch screen can include touch sense electrodes coupled to touch sense circuitry and drive lines that couple display pixels to display circuitry. In some examples, the touch screen can include display lines oriented along a first axis (e.g., vertically) and display lines oriented along a second axis (e.g., horizontally) that is orthogonal to the first axis. In some examples, the touch screen can include touch sense electrodes oriented along the second axis at locations of display lines oriented along the first axis and touch sense electrodes oriented along the first axis at locations of display liens oriented along the second axis.

Abstract: An input device includes a keycap, a first electrode disposed to move in response to movement of the keycap, a planar array of electrodes extending at least partially under the keycap, and a sensor. The planar array of electrodes includes a second electrode, a third electrode, and a fourth electrode extending between the second electrode and the third electrode. The sensor is coupled to at least one of the second electrode or the third electrode and configured to generate a signal indicative of a change in capacitive coupling between the second electrode and the third electrode. The change in the capacitive coupling may result from movement of the first electrode.

Abstract: Touch sensor panels/screens can include metal mesh touch electrodes and routing in the active area. In some examples, the touch sensor panel/screen can include row electrodes and column electrodes disposed over the active area of the display. In some examples, the routing traces for the row electrodes and/or column electrodes can be disposed in a border region and some of the routing traces for the row electrodes and/or column electrodes can be disposed in the active area. In some examples, some row electrodes can be shaved down to create an offset from the edge of the active area to accommodate routing traces in the active area. In some examples, the row electrodes can be formed in a first metal mesh layer and some routing traces in the active area can be formed in a second metal mesh layer, different from the first metal mesh layer.

Abstract: A touch sensor panel is disclosed. In some examples, the touch sensor panel includes drive electrodes and sense electrodes, wherein the drive electrodes and sense electrodes form touch nodes. In some examples, touch nodes include differently-sized drive and/or sense electrodes, and changes to the size or quantity of reference or floating electrodes disposed within the drive and/or sense electrodes are used to substantially balance the areas of the drive and/or sense electrodes in a given touch node.
