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 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.
