Abstract: Touch sensor configurations for reducing electrostatic discharge events in the border area of a touch sensor panel is disclosed. Touch sensors (e.g., electrodes formed on the cover material and/or the opaque mask) can be susceptible to certain events such as arcing and discharge/joule heating, which may negatively affect touch sensor performance. Examples of the disclosure can include increasing the trace width, spacing, and/or thickness in the border area relative to the trace width, spacing, and/or thickness in the visible/active area along one or more sides of the touch sensor panel. In some examples, touch electrodes can be located exclusively in the visible/active areas along one or more sides of the touch sensor panel, while dummy sections can be included in both the border and visible /active areas. Additionally or alternatively, one or more gaps between adjacent touch electrodes in the border area or serpentine routing can be included.

Abstract translation: 公开了用于减少触摸传感器面板的边界区域中的静电放电事件的触摸传感器配置。 触摸传感器（例如，在覆盖材料和/或不透明掩模上形成的电极）可能容易受到诸如电弧放电和放电/焦耳加热等某些事件的影响，这可能对触摸传感器性能产生负面影响。 本公开的示例可以包括增加边界区域中的迹线宽度，间隔和/或厚度相对于沿触摸传感器面板的一个或多个侧面的可见/活动区域中的迹线宽度，间隔和/或厚度。 在一些示例中，触摸电极可以沿着触摸传感器面板的一侧或多侧仅排列在可见/活动区域中，而伪区域可以包括在边界和可见/活动区域中。 另外或可选地，可以包括边界区域中的相邻触摸电极之间的一个或多个间隙或蛇形布线。
