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: This relates to touch sensor panels/touch screens including touch electrodes in a bar-and-stripe pattern. The bar-and-stripe pattern can improve touch signal levels for touch detection and improve uniformity of touch signal as objects move across the touch sensor panel/touch screen. Touch electrodes in a bar-and-stripe pattern can be formed from metal mesh in one or more layers of metal mesh. In some examples, “stripes” can be formed from groups of touch electrode segments in a first layer of metal mesh and can be interconnected by bridges formed in a second layer of metal mesh, different from the first layer of metal mesh, in the active area of the touch screen. Multiple stripes can be interconnected in the border area and/or in the active area to form a row touch electrode. In some examples, “bars” may also include bridges in the second layer of metal mesh.

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. The 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: 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.
