Visibility of the metal mesh touch electrodes can be mitigated using one or more mitigation techniques. In some examples, the boundary between touch electrodes and/or the boundary between a touch electrode and a routing trace of another touch electrode and/or the boundary between two routing traces can be non-linear. In some examples, dummy cuts can be made within an area of a touch electrode region (e.g., while maintaining the same electrical potential for the touch electrode region). In some examples, notches can be made in the metal mesh. In some examples, the location of cuts and/or notches can be optimized to mitigate visibility of the metal mesh. In some examples, some or all of the visibility mitigations may be used in combination in a touch screen. 本公开涉及采用可见性减弱措施的金属网格触摸电极。本文涉及使用一种或多种减弱技术来减弱金属网格触摸电极的可见性。在一些示例中，触摸电极之间的边界和/或触摸电极与另一个触摸电极的布线迹线之间的边界和/或两个布线迹线之间的边界可为非线性的。在一些示例中，可在触摸电极区的区域内形成虚拟切口(例如，同时保持所述触摸电极区的相同电势)。在一些示例中，可在所述金属网格中形成凹口。在一些示例中，可优化切口和/或凹口的位置以减弱所述金属网格的可见性。在一些示例中，所述可见性减弱措施中的一些或全部减弱措施可组合用于触摸屏中。
