具体实施方式
以下结合附图对本发明的具体实施方式进行详细说明。应当理解的是，此处所描述的具体实施方式仅用于说明和解释本发明，并不用于限制本发明。
本发明提供一种触控结构的实施方式，图1为本发明实施方式提供的触控结构的示意图。在本实施方式中，如图1所示，所述触控结构包括沿第一方向延伸的多条第一触控电极10，以及沿第二方向延伸的多条第二触控电极20，所述第一触控电极10和第二触控电极20交叉且绝缘设置，且每条所述第一触控电极10包括金属导线部100和透明电极部101，每条所述第二触控电极20包括金属导线部200和透明电极部201。具体地，在第一触控电极10和第二触控电极20的交错处，设置有绝缘层30，如图2所示，所述绝缘层30用于使第一触控电极10中的金属导线部100或透明电极部101与第二触控电极20中的金属导线部200或透明电极部201在所述交错处不相电连接。所述金属导线部100、200可以由银、铜、金、铝等导电性良好的金属或合金制备，所述透明电极部101、201可以为ITO电极、IZO电极、IGZO电极或InGaSnO电极等。所述第一方向、第二方向可以分别表示触控显示屏的行方向、列方向，当然，也可以反之。
如图1所示，第一触控电极10中的金属导线部100和透明电极部101间隔设置，第二触控电极20中的金属导线部200和透明电极部201间隔设置，可以避免形成连续且规律的金属网格，与现有技术中因采用整条金属电极而导致的金属网格相比，这样就可以在触控显示屏中改善摩尔纹现象，甚至避免出现摩尔纹，从而改善和提高触控 显示屏的显示效果；而与现有技术中采用ITO电极的方案相比，本实施方式中的触控结构减少了透明电极(ITO电极)的长度，可以降低成本，同时还可以提高信号在电极中的传输速度。
具体地，每条所述第一触控电极10中，金属导线部100的数量和透明电极部101的数量之和至少为三个，且所述金属导线部100与透明电极部101交替设置；以及，每条所述第二触控电极20中，金属导线部200的数量和透明电极部201的数量之和至少为三个，且所述金属导线部200与透明电极部201交替设置。可以理解，在每个第一触控电极10中，金属导线部100和透明电极部101的数量越多，每段金属导线部100的长度就越短，这样相比于单段金属导线部100的长度较大的情况，减少了形成连续且规律的金属网格的几率，可以进一步改善摩尔纹现象。因此，优选地，在制造工艺允许的情况下，第一触控电极10中，金属导线部100和透明电极部101的数量越多越好。第二触控电极20与第一触控电极10的情况类似，不再赘述。
当然，每条所述第一触控电极10中的金属导线部100和透明电极部101的数量，以及，每条所述第二触控电极20中的金属导线部200和透明电极部201的数量还可以为一个，如图3所示，虽然这样会不可避免地产生金属网格结构，但由于相邻金属导线之间的距离变大，或者仅在局部形成金属网格结构，与现有技术中因采用整条金属电极而导致的金属网格相比，这样也改善了摩尔纹现象。
优选地，如图1所示，每条第一触控电极10的金属导线部100在垂直于第一方向的方向上对应于和其相邻的第一触控电极10的透明电极部101；这样可以避免使得相邻的两条第一触控电极10的金属导线部100在第一方向上处于对应的位置，进而可以避免会因此而导致的摩尔纹现象。相应地，设置每条第二触控电极20的金属导线部200在垂直于第二方向的方向上对应于与其相邻的第二触控电极20的透明电极部201，以避免使得相邻的两条第二触控电极20的金属导线部200在第二方向上处于对应的位置。可以理解的是，任意两条第一触控电极10的金属导线部100在第一方向上的位置彼此错开，一条第一触控电极10的金属导线部100在第一方向上的位置可以与 相邻第一触控电极10的透明电极部101在第一方向上的位置重叠、部分重叠，也可以处于透明电极部101之内；相邻的第二触控电极20的金属导线部200与透明电极部201的位置关系与此类似，不再赘述。
除图1所示实施例外，在本实施方式中，如图4所示，还可以在每条第一触控电极10的金属导线部100和相邻的第一触控电极10的透明电极部101在第一方向上的位置对应的情况下，设置每条第二触控电极20的金属导线部200与相邻的第二触控电极20的金属导线部200在第二方向上的位置对应。虽然这样可能会在第二方向上出现摩尔纹现象，但与现有技术相比，同样也改善了摩尔纹现象。当然，也可以反之，以避免在第二方向上产生摩尔纹现象。
类似地，如图5所示，在本实施方式中，还可以设置相邻的两条第一触控电极10的金属导线部100在第一方向上的位置彼此对应；设置相邻的两条第二触控电极20的金属导线部200在第二方向上的位置彼此对应。
在本实施方式中，除上述第一触控电极10、第二触控电极20均包括金属导线部和透明电极部的实施例外，还可以设置仅第一触控电极10包括金属导线部100和透明电极部101。这样设置可以在第一方向上避免产生摩尔纹，从而改善显示效果。可以理解，在此情况下，可以设置所述金属导线部100的数量和透明电极部101的数量之和至少为三个，且所述金属导线部100与透明电极部101交替设置，以减少形成连续且规律的金属网格的几率，更好地避免产生摩尔纹现象。同时，也可以设置每条所述第一触控电极10的金属导线部100在第一方向上的位置对应于和其相邻的所述第一触控电极10的透明电极部101，或者，设置每条所述第一触控电极10的金属导线部100在第一方向上的位置对应于和其相邻的所述第一触控电极10的金属导线部100。
在本实施方式中，如图6所示，所述触控结构还可以包括：沿第一方向延伸的多条第一透明电极11，所述第一透明电极11与第一触控电极10间隔设置；和/或，沿第二方向延伸的多条第二透明电极 21，所述第二透明电极21与第二触控电极20间隔设置。这样设置可以增加相邻两个第一触控电极10，和/或增加相邻两个第二触控电极20之间的距离，这就使相邻两个第一触控电极10的金属导线部100之间的距离，和/或，相邻两个第二触控电极20的金属导线部200之间的距离变大，从而可以进一步改善摩尔纹现象。优选地，每两条相邻的第一触控电极10之间设置至少一条第一透明电极11，每两条相邻的第二触控电极20之间设置至少一条第二透明电极21，以在第一方向和第二方向均匀地改善摩尔纹现象。
在本实施方式中，所述触控结构还包括：沿第一方向延伸的多条第一金属电极12，和/或，沿第二方向延伸的多条第二金属电极22；其中，第一金属电极12的设置方式，如图7所示，所述第一金属电极12与第一触控电极10间隔设置；或者，如图8所示，所述第一金属电极12与第一触控电极10、第一透明电极11间隔设置。第二金属电极22的设置方式如图7所示，所述第二金属电极22与第二触控电极20间隔设置；或者，如图8所示，所述第二金属电极22与第二触控电极20、第二透明电极21间隔设置。这样设置可以进一步减少透明电极的长度，从而可以进一步降低生产成本，以及获得更快的信号传输速度。
综上所述，本发明实施方式提供的触控结构，其第一触控电极10和/或第二触控电极20中，金属导线部和透明电极部间隔设置，这样可以避免连续且规律的金属网格出现，与现有技术中因采用金属电极而导致的金属网格相比，这样就可以在触控显示屏中改善摩尔纹现象，甚至避免出现摩尔纹，从而改善和提高触控显示屏的显示效果；而与现有技术中采用ITO电极的方案相比，本实施方式中的触控结构减少了透明电极(ITO电极)的长度，可以降低成本，同时还可以提高信号在电极中的传输速度。
本发明还提供另一种触控结构的实施方式，图9为本发明实施方式提供的另一种触控结构的示意图。在本实施方式中，如图9所示，所述触控结构包括沿第一方向延伸的多条第一电极，以及沿第二方向延伸的多条第二电极，所述多条第一电极包括多条第一金属电极12 和多条第一透明电极11，且每相邻两条第一金属电极12之间有至少一条第一透明电极11；和/或，所述多条第二电极包括多条第二金属电极22和多条第二透明电极21，且每相邻两条第二金属电极22之间有至少一条第二透明电极21。
在本实施方式中，在第一方向和/或第二方向，将透明电极和金属电极间隔设置，且相邻的金属电极之间设有至少一条透明电极，这样可以使相邻的金属电极之间的距离增大，从而与现有技术中因采用金属电极而导致的金属网格相比，本实施方式提供的触控结构中的金属网格的密度减小，改善了摩尔纹现象；而与现有技术中采用ITO电极的方案相比，本实施方式中的触控结构减少了透明电极(ITO电极)的长度，可以降低成本，同时还可以提高信号在电极中的传输速度。
