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: 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.
