应当理解的是，以上的一般描述和后文的细节描述仅是示例性的，并不能限制本公开。
附图说明
此处的附图被并入说明书中并构成本说明书的一部分，示出了符合本公开的实施例，并于说明书一起用于解释本公开的原理。
图1A是根据一示例性实施例示出的一种具有静电防护结构的触控电路的结构示意图；
图1B是根据一示例性实施例示出的一种第一尖端结构处的静电荷释放到第二尖端结构的示意图。
具体实施方式
这里将详细地对示例性实施例进行说明，其示例表示在附图中。下面的描述涉及附图时，除非另有表示，不同附图中的相同数字表示相同或相似的要素。以下示例性实施例中所描述的实施方式并不代表与本公开相一致的所有实施方式。相反，它们仅是与如所附权利要求书中所详述的、本公开的一些方面相一致的装置和方法的例子。
图1A是根据一示例性实施例示出的一种具有静电防护结构的触控电路的结构示意图，如图1A所示，该触控电路包括：信号传输通道101和接地通道102。
信号传输通道101的末端设置有向外凸起的具有针尖状顶端的第一尖端结构103；
接地通道102上设置有针尖状顶端与第一尖端结构103的针尖状顶端相对的第二尖端结构104；
这里的第一尖端结构103和第二尖端结构104可以是三角形或其他具有针尖状顶端的结构。第一尖端结构103处于信号传输通道101的末端处，第二尖端结构104处于接地通道102上，第一尖端结构103的针尖状顶端与第二尖端结构104的针尖状顶端是相对的，并由此组成一个用于释放静电的尖端组。每条信号传输通道101与接地通道102之间都设置有该尖端组。通常，触控电路中的第一尖端结构103的数量与第二尖端结构104的数量 相等。
在实际实现时，信号传输通道101可以为一个、两个或多个，接地通道102可以为一个、两个或多个，本实施例对信号传输通道101的数量以及接地通道102的数量不作限定。
相对的一组第一尖端结构103和第二尖端结构104中，第一尖端结构103的针尖状顶端指向第二尖端结构104的针尖状顶端。
可选的，第一尖端结构103也可以处在信号传输通道101上的其他位置，本实施例对此不作限定。
由静电场电势分布公式得知，静电场中电荷密度与曲率半径R有着反比例关系，在不同的曲率下，电荷通常分布在曲率较大的地方。也就是说，根据静电场分布，单一导体在相同情况下，曲率较大的位置更易集聚电荷。因此，在触控电路中的某条电路通道上，具有针尖状顶端的尖端结构处的曲率较大，能够聚集更多的静电荷。
在实际应用时，信号传输通道101的末端设置的向外凸起的具有针尖状顶端的第一尖端结构103能够聚集信号传输通道101上的静电荷；接地通道102上设置的向外凸起的具有针尖状顶端的第二尖端结构104能够聚集接地通道102上的静电荷。且由于第一尖端结构103与第二尖端结构104的针尖状顶端处的曲率最大，因此静电荷会聚集到第一尖端结构103与第二尖端结构104的针尖状顶端处。
信号传输通道101上的第一尖端结构103的针尖状顶端用于聚集信号传输通道101上的静电荷，并将聚集后的静电荷释放到与该第一尖端结构103相对的位于接地通道102上的第二尖端结构104上。
信号传输通道101上的第一尖端结构103的针尖状顶端与接地通道102上的第二尖端结构104的针尖状顶端是相对的，当第一尖端结构103的针尖状顶端处聚集一定数量的静电荷后，由于第一尖端结构103的针尖状顶端处的电势高于第二尖端结构104的针尖状顶端处的电势，因此，在第一尖端结构103的针尖状顶端处聚集的静电荷将释放到第二尖端结构104的针尖状顶端处。
举例来讲，请参见图1B，其是根据一示例性实施例示出的一种第一尖端结构处的静电荷释放到第二尖端结构的示意图。如图1B所示，第一尖端结构103的针尖状顶端1031处聚集大量静电荷后，由于第一尖端结构103的针尖状顶端1031处的电势高于第二尖端结构104的针尖状顶端1041处的电势，第一尖端结构103的针尖状顶端1031处聚集的静电荷释放到了第二尖端结构104的针尖状顶端1041处。
第二尖端结构104上的针尖状顶端用于接收第一尖端结构103上的针尖状顶端释放的静电荷，并将静电荷导向接地通道102。
当接地通道102上第二尖端结构104上的针尖状顶端接收到第一尖端结构103上的针尖状顶端释放的静电荷后，第二尖端结构104的针尖状顶端处的电势将高于接地通道102上的其他位置，因此，第二尖端结构104的针尖状顶端处的静电荷将通过接地通道102流向该接地通道102上的低电势处。
第一尖端结构103上的针尖状顶端与第二尖端结构104上的针尖状顶端之间的距离小于预定距离阈值。
为了使得在第一尖端结构103上的针尖状顶端处聚集的静电荷能够成功地释放到第二尖端结构104上的针尖状顶端处，第一尖端结构103上的针尖状顶端与第二尖端结构104上的针尖状顶端之间的距离需要小于预定距离阈值。
接地通道102用于为第二尖端结构104接收到的静电荷提供流转回路。
在第二尖端结构104没有接收到第一尖端结构103释放的静电荷时，第二尖端结构104处的电势与接地通道102上的其他位置处的电势基本相等。当第二尖端结构104接收第一尖端结构103释放的静电荷后，第二尖端结构104处的电势高于接地通道102上的其他位置处的电势，此时，第二尖端结构104处的静电荷将通过该接地通道102流向该接地通道102上的低电势处。
信号传输通道101与触控芯片和触控面板连接，信号传输通道101用于接收触控面板上产生的电容值以及承载触控芯片的驱动信号。
这里的信号传输通道101可以是电容值接收电路通道或驱动信号发送电路通道。
电容值接收电路通道能够将触控面板上产生的电容值反馈给触控芯片；而驱动信号发送电路通道则能够承载触控芯片的驱动信号。
可选的，第一尖端结构103可以是在蚀刻信号传输通道101时蚀刻得到的；第二尖端结构104是在蚀刻接地通道102时蚀刻得到的。
由于第一尖端结构103和第二尖端结构104都可以在对触控面板蚀刻触控电路时蚀刻得到，因此并不需要额外增加其他材料，节省了制作成本。
可选的，为了不影响信号传输通道101的正常工作，在蚀刻第一尖端结构103时，可以在保证第一尖端结构103对静电荷的聚集效果的前提下，将第一尖端结构103蚀刻得尽可能小。
综上所述，本公开实施例中提供的具有静电防护结构的触控电路，通过由信号传输通道的末端的第一尖端结构聚集静电荷，并将聚集的静电荷释放到与该第一尖端结构相对的位于接地通道上的第二尖端结构上；由于能够通过将静电荷释放到接地通道上来消除静电对触控电路的伤害，因此解决了添加静电防护器件只是将静电荷进行阻隔，当聚集的静电荷过多时同样会对触控电路造成伤害的问题；达到了提高触控电路的抗静电性能的效果。
另外，通过将第一尖端结构上的针尖状顶端与第二尖端结构上的针尖状顶端之间的距离设置为小于预定距离阈值的距离；解决了由于第一尖端结构上的针尖状顶端与第二尖端结构上的针尖状顶端之间的距离太远而无法实现静电荷释放的问题；达到了提高触控电路中静电荷的释放效果的效果。
另外，通过在蚀刻信号传输通道时蚀刻得到第一尖端结构，在蚀刻接地通道时蚀刻得到第二尖端结构；解决了由于添加静电防护器件而导致触控电路的制作成本较高的问题；达到了降低触控电路的制作成本的效果。
