技术领域
本专利申请属于电容式触摸传感器技术领域，尤其涉及一种能触控终端设备屏幕边缘的电容式触摸传感器结构。
背景技术
随着电容屏的不断发展，电容式触摸屏在终端设备中越来越广泛的应用，电容式触摸屏设备中的触摸传感器的电极需要连出线与触摸传感器的处理电路电连接，连出线可以将电极所采集到的信号输送到处理电路，进行处理，处理电路位于电容式触摸传感器结构两端部中的任一端部，由于现有的电容式触摸屏设备需要通过在边缘走线来连接触控电极模块，因此，几乎所有的电容式触摸屏都是有边框设计的。因此，目前采用电容式触摸屏的终端设备屏幕的边缘无法触控到，无法在部分实施例中在边缘上实现无实体按键、边缘冷屏解锁等触控技术功能。
发明内容
本专利申请部分实施例所要解决的技术问题在于提供一种电容式触摸传感器结构，旨在解决现有技术中的电容式触摸传感器无法 在终端设备屏幕的边缘上实现触控的问题。
本专利申请部分实施例是这样实现的，一种电容式触摸传感器结构，包括至少两个互电容组，每个互电容组包括X电极组以及Y电极组，每个X电极组包括至少两个X电极，每个Y电极组包括至少两个Y电极，相邻的两个X电极之间设置有间隙；
每一X电极组中相邻的两个X电极之间通过搭桥电连接，靠近所述电容式触摸传感器结构两端的两个X电极组为边缘X电极组，所述两个边缘X电极组与处理电路电连接，位于两个边缘X电极组之间的X电极组为中间X电极组，每一组所述的中间X电极组延伸出至少一伸长部；所述间隙包括第一间隙以及第二间隙，所述伸长部设置于所述第一间隙内，并且穿过所述搭桥，与处理电路连接；所述Y电极与所述处理电路电连接。
在部分实施例中，每一X电极组中的所有X电极均沿所述电容式触摸传感器结构所在平面的X轴方向依次排列，所有的X电极组沿所述平面的Y轴方向依次排列；所述Y电极设置于所述的第二间隙内，并且穿过所述搭桥，与电路连接。
在部分实施例中，一条所述的第一间隙内设置有一个伸长部；一条所述的第二间隙内设置有一个Y电极。
在部分实施例中，一条所述的第一间隙内设置有两个伸长部，相邻两条第二间隙内分别设置有部分Y电极，相邻两条第二间隙内的部分Y电极的端部相互电连接。
在部分实施例中，于电容式触摸传感器结构内所有的所述第一 间隙内依次交替地设置单根、双根伸长部；所有的所述第二间隙内则均设置有部分Y电极，相邻两条第二间隙内的部分Y电极的端部相互电连接。
在部分实施例中，所述电容式触摸传感器结构包括第一绝缘介质层以及第二绝缘介质层，所述X电极组以及伸长部均固定于所述第一绝缘介质层上；所述搭桥连接于相邻两个X电极的顶部之间，所述第二绝缘介质层设置在所述搭桥上，所述Y电极组设置在所述第二绝缘介质层上，且与所述搭桥绝缘。
在部分实施例中，所述第一绝缘介质层以及第二绝缘介质层的材料为玻璃或胶片。
在部分实施例中，所述X电极对应于所述搭桥的位置处设置有伸入所述第一间隙的搭桥部，所述搭桥连接于相邻两个X电极的搭桥部之间。
在部分实施例中，所述X电极和/或Y电极的形状为矩形或三角形。
在部分实施例中，所述X电极和/或Y电极的边缘形状呈直线、曲线或锯齿状。
本专利申请部分实施例与现有技术相比，有益效果在于：本专利申请部分实施例的电容式触摸传感器结构中，相邻的两个X电极之间通过搭桥电连接，中间X电极组均延伸出一伸长部，伸长部设置于第一间隙内，并且穿过搭桥，与处理电路连接，因此，各个X电极均可以通过搭桥的下方连接到处理电路，同时，Y电极的端部与 处理电路电连接。所以电容式触摸传感器结构两侧边的位置无需走线，从而可实现无边框设计，并且能在终端设备屏幕的边缘上实现触控，使触摸屏在视觉上更优美。还可以腾出边缘位置实现无实体按键、边缘冷屏解锁等触控功能。

具体实施方式
为了使本专利申请部分实施例所要解决的技术问题、技术方案及有益效果更加清楚明白，以下结合附图及实施例，对本专利申请部分实施例进行进一步详细说明。应当理解，此处所描述的具体实施例仅仅用以解释本专利申请，并不用于限定本专利申请。
如图1所示，为本专利申请的实施例一，一种电容式触摸传感器结构，包括至少两个互电容组，每个互电容组包括X电极组1以及Y电极组2。每个X电极组1包括至少两个X电极11，每个Y电极组2包括至少两个Y电极21，相邻的两个X电极11之间设置有一条间隙100。
每一X电极组1中相邻的两个X电极11之间通过搭桥3(搭桥指的是一种用于将两块电极电连接起来的导电物质)电连接，靠近电容式触摸传感器结构两端的两个X电极组1为边缘X电极组。两个边缘X电极组与处理电路电连接，位于两个边缘X电极组之间的X电极组1为中间X电极组，每一组中间X电极组均延伸出至少一 伸长部111。上述间隙包括第一间隙100a以及第二间隙100b，伸长部111设置于第一间隙100a内，并且穿过搭桥3，与处理电路连接。Y电极21与处理电路电连接。
具体地，每一X电极组1中的所有X电极11均沿电容式触摸传感器结构所在平面的X轴方向依次排列，所有的X电极组1沿平面的Y轴方向依次排列。Y电极21设置于第二间隙100b内，并且穿过搭桥3，与处理电路连接。
一条第一间隙100a内设置有一个伸长部111，一条第二间隙100b内设置有一个Y电极21，Y电极21、伸长部111于平面的X轴方向依次交替分布。
为了缩短搭桥3的长度，上述提及的X电极11对应于搭桥3的位置处设置有伸入第一间隙100a的搭桥部112，搭桥3连接于相邻两个X电极11的搭桥部112之间。
本实施例的电容式触摸传感器结构中，相邻的两个X电极11之间通过搭桥3电连接，中间X电极组均延伸出一伸长部111，伸长部111设置于第一间隙100a内，并且穿过搭桥3，与处理电路连接，因此，各个X电极11均可以通过搭桥3的下方连接到处理电路，同时，Y电极21的端部与处理电路电连接。所以电容式触摸传感器结构两侧边的位置无需走线，从而可实现无边框设计，并且能在终端设备屏幕的边缘上实现触控，使触摸屏在视觉上更优美。还可以腾出边缘位置实现无实体按键、边缘冷屏解锁等触控功能。
请参见图2至图3c，为本专利申请的实施例二，与实施例一 的不同之处在于，其一条第一间隙100a内设置有两个伸长部111，一条第二间隙100b内设置部分Y电极21，(此处的部分Y电极21是指整个Y电极21的一部分，而不是指整个Y电极21)；优先地，本实施例的部分Y电极21刚好是整个Y电极21的一半。两条相邻的第二间隙100b内的部分Y电极21的端部电连接。如图2所示，两个部分Y电极21的端部之间可通过连接件210进行电连接，形成一个Y电极21。当然，两个部分Y电极21也可以通过处理电路进行电连接，在此不再赘述。如图3所示，相邻两条第二间隙100b内的部分Y电极21还可由一整体的Y电极21弯折而成，弯折处211位于电容式触摸传感器结构的端部位置。部分Y电极21、另一部分Y电极21、两个伸长部111于平面的X轴方向上依次交替分布。本实施例的X电极组1、Y电极组2均平铺在同一个水平面上。本实施例相比于实施例一，减少了第一间隙100a的数量，由于在实际应用中，第一间隙100a的宽度要比第二间隙100b大很多，因此，减少第一间隙100a的数量，能使传感器结构在同一宽度范围内布置更多互电容组。
请参见图4a及图4b，为本专利申请的实施例三，与上述两个实施例不同之处在于，本实施例的电容式触摸传感器结构将X电极组1、Y电极组2设置在不同的层面上。例如，电容式触摸传感器结构设置有第一绝缘介质层200以及第二绝缘介质层300。X电极组1以及伸长部111均固定于第一绝缘介质层200上；搭桥3连接于相邻两个X电极11的顶部之间。第二绝缘介质层300设置在搭桥3上， Y电极组2设置在第二绝缘介质层300上，并且Y电极组2与搭桥3绝缘。第一绝缘介质层200以及第二绝缘介质层300的材料可为玻璃、胶片等材料。相对比实施例一及二，本实施例，将X电极组11与Y电极21组布置在不同的水平面上，将X电极组1与Y电极组2于竖向方向的错开，因此，在一水平面上只需布置一种电极，在互电容组数量一定的情况下，本实施例可将传感器结构的将宽度做得更小，有利于触控产品精细化。
请参见图5，为本专利申请的实施例四，本实施例提供了一种单、双根伸长部111结合走线的结构，电容式触摸传感器结构内所有的第一间隙100a内依次交替地设置单根、双根伸长部111，而第二间隙100b内则均设置有一个Y电极21。本实施例相比于实施例二，其第一间隙100a数量增加，但该传感器结构中一个单位面积内的互电容组的分布密度较大，提高了传感器的对触摸位置的感应精度。
请参见图6至图7b，为本专利申请的实施例五，提供了一种双感应电容式触摸传感器结构，一个X电极11同时对应两个Y电极21，X1Y1为一坐标，X1Y2为另一坐标。此结构的优处是X电极11数量减少，在纵向穿过两X电极之间的走线数也减少。
在实际应用中，上述实施方式中的搭桥3的材料为氧化铟锡或金属网格；X电极11和/或Y电极21的形状不限定，可以是矩形、三角形或者其他不规则的形状。同样地，X电极11和/或Y电极21的边缘形状亦不限定，边缘形状可以是直线、曲线或锯齿等形状。
以上所述仅为本专利申请的较佳实施例而已，并不用以限制本 专利申请，凡在本专利申请的精神和原则之内所作的任何修改、等同替换和改进等，均应包含在本专利申请的保护范围之内。
