摘要:
A ring electrode to determine the orientation of the stylus relative to the surface. The stylus can include a ring electrode configuration which can improve capacitive coupling between the ring electrode and the touch panel. The ring electrode configuration can include a ring electrode and ground ring, and ground plate. By varying the lengths of ring electrode, ground ring, ground plate, and the distance between these elements, the electric field emanating from the ring electrode can be tuned to optimize the capacitive coupling between the ring electrode and surface. In some examples, the ring electrode can include multiple sub-rings. In some examples, the ring electrode can comprise a crown shape including projections, each having a width that tapers to a minimum width along the length of the ring electrode.
摘要(中):
用于确定触针相对于表面的取向的环形电极。 触针可以包括可以改善环形电极和触摸面板之间的电容耦合的环形电极配置。 环形电极配置可以包括环形电极和接地环以及接地板。 通过改变环形电极,接地环,接地板的长度以及这些元件之间的距离,可以调节从环形电极发出的电场,以优化环形电极和表面之间的电容耦合。 在一些示例中,环形电极可以包括多个子环。 在一些示例中,环形电极可以包括冠状形状,其包括凸起,每个凸起的宽度沿着环形电极的长度逐渐变细到最小宽度。
