Abstract: In some examples, a touch screen includes a first region corresponding to a region of the touch screen without touch electrodes; a second region corresponding to a region of the touch screen with a first conductive material (e.g., solid metal) with a first density in a first conductive layer; and a third region corresponding to a region of the touch screen with a second conductive material (e.g., metal mesh) with a second density, lower than the first density, in the first conductive layer. In some examples, the second region circumscribes the first region, and the third region circumscribes the second region. Some touch electrodes include a portion of the first conductive material in the second region and a portion of the second conductive material in the third region. Such touch electrodes can be routed using the first conductive material in the first conductive layer around the first region.

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: Touch electrode architecture techniques can be used to reduce or eliminate metal mesh within the one or more high-transmittance regions of a touch screen including one or more high-transmittance regions. In some examples, one or more optical devices can be integrated with a touch screen such that light associated with the one or more optical devices passes through one or more layers of the touch screen. In some such examples, to avoid degrading performance of the optical devices, one or more high-transmittance regions can be used. Additionally or alternatively, in some examples, the high-transmittance can be achieved using touch electrode architecture techniques that use transparent or semi-transparent materials instead of opaque metal mesh within the high-transmittance regions.

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.

Abstract: A touch sensor panel is disclosed. In some examples, the touch sensor panel comprises a first layer including a plurality of drive lines including drive electrodes, wherein the drive lines are configured to be coupled to drive circuitry during touch sensing on the touch sensor panel. In some examples, the first layer includes a plurality of sense lines including sense electrodes, wherein the sense lines are configured to be coupled to sense circuitry during the touch sensing on the touch sensor panel. In some examples, the first layer includes a plurality of first shielding electrodes, wherein the first shielding electrodes are disposed between the drive electrodes and the sense electrodes. In some examples, the touch sensor panel comprises a second layer, different than the first layer, including one or more bridges electrically coupling at least two of the first shielding electrodes together.

Abstract: Touch sensor configurations for reducing electrostatic discharge events in the border area of a touch sensor panel is disclosed. Touch sensors (e.g., electrodes formed on the cover material and/or the opaque mask) can be susceptible to certain events such as arcing and discharge/joule heating, which may negatively affect touch sensor performance. Examples of the disclosure can include increasing the trace width, spacing, and/or thickness in the border area relative to the trace width, spacing, and/or thickness in the visible/active area along one or more sides of the touch sensor panel. In some examples, touch electrodes can be located exclusively in the visible/active areas along one or more sides of the touch sensor panel, while dummy sections can be included in both the border and visible/active areas. Additionally or alternatively, one or more gaps between adjacent touch electrodes in the border area or serpentine routing can be included.
