Abstract: Electrode configurations for reducing wobble error for a stylus translating on a surface over and between electrodes of a touch sensor panel are disclosed. In some examples, electrodes associated with a more linear signal profile are correlated with lower wobble error. In some examples, electrodes can have projections which can interleave with projections of adjacent electrodes. In some configurations, projections of adjacent electrodes can be interleaved in one-dimension; in other configurations, projections of adjacent electrodes can be interleaved in two-dimensions. In some configurations, the width and length of one or more projections in an electrode can be selected based on a desired signal profile for that electrode.

Abstract translation: 公开了用于减少在触摸传感器面板的电极之间的表面上平移的触控笔的摆动误差的电极配置。 在一些示例中，与更线性的信号轮廓相关联的电极与较低的摆动误差相关。 在一些示例中，电极可以具有可以与相邻电极的突起交错的突起。 在一些配置中，相邻电极的投影可以一维交错; 在其它构造中，相邻电极的突出可以二维交错。 在一些配置中，电极中的一个或多个突起的宽度和长度可以基于该电极的期望信号轮廓来选择。
