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.
