相关申请的交叉引用
本申请主张在2016年5月9日在中国提交的中国专利申请号No.201610300661.5的优先权，其全部内容通过引用包含于此。
技术领域
本公开涉及触控显示技术领域，尤其涉及一种触摸屏和触控装置。
背景技术
近年来，电容式触摸屏技术在显示领域飞速发展。电容式触控技术主要划分为In-Cell(内嵌式)、OGS(One glass solution，单片玻璃)和On-Cell(外嵌式)三种技术，其中，On-Cell技术是指将触控电极集成到显示面板的基板外侧，由于工艺简单，设备不需要改造，面板商多采用此技术。On-cell技术又包括MLOC(Multi-layer on cell，多层外嵌式)和SLOC(Single-layer on cell，单层外嵌式)两种技术，后者由于只需要一次曝光工艺，优势明显，因此逐步成为On cell触摸屏技术的主流方案。
然而，在当前的SLOC触摸屏中，当从某个角度观察时，由于部分走线反光而部分走线不反光，可能会导致交替的明暗条纹，从而影响显示装置的显示效果。
发明内容
有鉴于此，本公开提供一种触摸屏和触控装置，以解决现有的折线型的触控电极在某一角度观察时部分走线反光部分走线不反光导致出现明暗条纹的问题。
为解决上述技术问题，本公开提供一种触摸屏，包括：基板以及设置于所述基板上的同层设置的多个呈矩阵方式排列的触控电极，每一所述触控电极包括至少两段子电极线，各子电极线顺次相接形成呈折线型的所述触控电极，所述基板划分为多个分区，每一所述分区中设置有至少一个所述触控电 极，处于同一分区中的各触控电极的图形相同，所述多个分区包括至少两种分区，所述至少两种分区中的触控电极的图形不同。
可选地，所述分区呈矩阵方式排列，同一行或同一列的分区中，至少包括第一分区和第二分区，所述第一分区和第二分区中的触控电极的图形不同。
可选地，所述第一分区包括第一子电极线，所述第二分区中包括第二子电极线，所述第一子电极线和第二子电极线位于同一行或同一列，所述第一子电极线和第二子电极线不平行。
可选地，所述第一子电极线和第二子电极线呈八字形或倒八字形。
可选地，所述第一分区和所述第二分区中的触控电极的弯折角度不同。
可选地，所述第一分区和第二分区交替设置。
可选地，每一分区的大小相同。
可选地，每一所述分区中包括至少一行至少一列所述触控电极。
可选地，位于同一行或同一列的多个分区中，第奇数个分区中的触控电极的图形相同，第偶数个分区中的触控电极的图形相同，且第奇数个分区中的触控电极与第偶数个分区中的触控电极的图形不同。
可选地，同一行和/或同一列的相邻两个分区中的触控电极轴对称设置。
可选地，所述触控电极包括驱动电极和感应电极，同一行和/或同一列的相邻两个分区中，一个分区设置驱动电极，一个分区设置感应电极。
可选地，所述触摸屏还包括：
补充图形，位于触控电极图形不同的相邻的两分区之间，用于填充所述两分区之间的空白区域。
可选地，所述触摸屏为单层外挂式触摸屏。
本公开还提供一种触控装置，包括上述触摸屏。
本公开的上述技术方案的有益效果如下：
触摸屏的基板上至少存在两个分区，所述两个分区中的触控电极的图形不同。因而，属于不同的分区，且位于同一行或同一列的子电极线的走向可能不同，走向不同的子电极线的边缘不会向同一方向反射光线，因而可以打断因行或列中的所有子电极线的走向均相同而造成的连续的明暗条纹，优化了显示效果。

具体实施方式
除非另作定义，此处使用的技术术语或者科学术语应当为本公开所属领域内具有一般技能的人士所理解的通常意义。本公开专利申请说明书以及权利要求书中使用的“第一”、“第二”以及类似的词语并不表示任何顺序、数量或者重要性，而只是用来区分不同的组成部分。同样，“一个”或者“一”等类似词语也不表示数量限制，而是表示存在至少一个。“连接”或者“相连”等类似的词语并非限定于物理的或者机械的连接，而是可以包括电性的连接，不管是直接的还是间接的。“上”、“下”、“左”、“右”等仅用于表示相对位置关系，当被描述对象的绝对位置改变后，则该相对位置关系也相应地改变。
请参考图1，图1为相关技术中SLOC触摸屏的结构示意图。该SLOC触摸屏包括同层设置的触控驱动电极(TX)11和触控感应电极(RX)12，触控驱动电极11和触控感应电极12均呈折线型。触控驱动电极11和触控感应电极12通常采用透明金属氧化物(如ITO)制备，请参考图2，在电极走线边缘，由于存在坡度角，外界光线31照射时，会在坡度角上发生反射，产生反射光线32。又由于触控电极采用折线设计，包括沿两个方向的走线21和22，因此从某个角度观察时，只能看到一个方向的走线上的反光，无法看 到另一方向的走线上的反光，如图2中，只能看到走线21上的反光，图1和图2中采用黑色加粗线表示在某一角度观察时，触控电极的反光部分。请参考图3，这在宏观上表现为纵向交替的明暗条纹，这极大地影响显示装置的显示效果。
本公开实施例提供一种触摸屏，包括：基板以及设置于所述基板上的同层设置的多个呈矩阵方式排列的触控电极，每一触控电极包括至少两段子电极线，各子电极线顺次相接形成呈折线型的触控电极，基板划分为多个分区，每一分区中设置有至少一个触控电极，处于同一分区中的各触控电极的图形相同，该多个分区包括至少两种分区，上述的至少两种分区中的触控电极的图形不同。
其中，各子电极线顺次相接，是指各子电极线的首尾顺次相接，举例来说，一个触控电极包括三段子电极线，第一段子电极线的尾部与第二段子电极线的头部相接，第二段子电极线的尾部与第三段子电极线的头部相接。
其中，两触控电极的图形相同，是指两触控电极的图形可完全重叠，而两触控电极的图形不同，是指两触控电极的图形不能够完全重叠。
由于存在上述至少存在两个触控电极的图形不同的分区，因而，属于不同的分区，且位于同一行或同一列的子电极线的走向可能不同，走向不同的子电极线的边缘不会向同一方向反射光线，因而可以打断因行或列中的所有子电极线的走向均相同而造成的连续的明暗条纹，优化了显示效果。
所谓子电极线的走向即子电极线的延伸方向，延伸方向不同的子电极线不平行。
本公开实施例中，分区可以任意划分，可选地，分区呈矩阵方式排列。
为了减少因同一行或同一列的子电极线走向相同而造成的连续的明暗条纹，可选地，同一行或同一列的分区中，至少包括第一分区和第二分区，第一分区和第二分区中的触控电极的图形不同。
进一步可选地，第一分区包括第一子电极线，第二分区中包括第二子电极线，第一子电极线和第二子电极线位于同一行或同一列，第一子电极线和第二子电极线不平行，从而可避免因同一行或同一列的子电极线走向相同而造成的连续的明暗条纹。
可选地，第一子电极线和第二子电极线呈八字形或倒八字形。
可选地，第一分区和第二分区交替设置。
下面将结合附图和实施例，对本公开的具体实施方式作进一步详细描述。以下实施例用于说明本公开，但不用来限制本公开的范围。
请参考图4，图4为本公开至少一个实施例的触摸屏的结构示意图，触摸屏包括基板40以及设置于基板40上的同层设置的多个呈矩阵方式排列的触控电极50，每一触控电极50包括六段子电极线51，各子电极线51首尾顺次相接形成呈折线型的触控电极50，本公开实施例中，每一触控电极线50中，奇数段的多个子电极线均平行设置，且图形相同，偶数段的多个子电极线均平行设置，且图形相同。基板40划分为多个分区41，每一分区41中设置有三个触控电极50，位于同一分区中的触控电极50的图形相同，至少存在两个分区41，两个分区41中的触控电极50的图形不同。
本实施例中，基板40上划分的多个分区41呈矩阵方式排列，且每一分区41的大小相同，图4中，仅示出基板40上的四个分区41，该四个分区41位于同一行，从图4中可以看出，同一行分区中，所有奇数列分区41中的触控电极50的图形相同，所有偶数列分区41中的触控电极50的图形相同，且相邻的两个分区41中的触控电极50的图形不同。本公开实施例中，相邻的两个分区41中的触控电极50沿径向线L轴对称设置。
从图4中可以看出，位于同一行的多个子电极线51中，部分子电极线51朝向一个方向延伸，另一部分子电极线51朝向另一方向延伸，即位于同一行的多条子电极线51中存在走向不同(即不平行)的子电极线，因而，当从某一角度观察时，一行子电极线51中，只有部分子电极线51的边缘反射光线，因而，难以形成连续的明暗条纹，从而优化了显示效果。
本公开实施例中，触控电极50采用透明导电材料制成，可选地，选用透明金属氧化物，如ITO，IZO等。
本公开实施例中，触控电极50均采用折线型，折线型的触控电极与竖线型的触控电极相比，不会与显示面板中的像素单元发生摩尔个纹。
上述实施例中，每一触控电极50包括六段子电极线51，在本公开的其他一些实施例中，每一触控电极50包括的子电极线51的数量不限，每一触 控电极50包括至少两段子电极线51即可形成呈折线型的触控电极线。请参考图5，图5所示的实施例中，每一触控电极50包括两段子电极线51。
上述实施例中，基板40划分为多个分区41，多个分区41的大小相同，且呈矩阵方式排列，当然，在本公开的其他一些实施例，基板40上也可以包括大小不同的分区41，请参考图6所示的实施例。
图4所示的实施例中，每一分区41中设置有三个触控电极50，当然，在本公开的其他一些实施例中，分区41中设置的触控电极50的个数不限，为至少一个即可，且，各个分区41中的触控电极50的个数也可以不相同。例如，如图6所示的实施例中，最左侧的区域41中具有八个触控电极50，而位于中间的分区41中仅包括四个触控电极50。
上述各实施例中，基板40上至少存在两个分区，两个分区41中的触控电极50的形状不同，从而可以避免处于同一行的子电极线走线方向一致，从某一方向观察时，不会影响连续的明暗条纹，优化了显示效果。
本公开实施例的触控电极中，相连的两段子电极线构成一个弯折图形，上述实施例中，属于触控电极形状不同的两个分区中，位于同一行的弯折图形向相反的方向弯折，以使得属于触控电极形状不同的分区中且位于同一行的子电极线不平行，从而来避免出现明暗相间条纹的目的。
上述实施例中，通过改变同一行的部分触控电极的弯折图形的弯折方向，来避免出现明暗相间条纹的目的，当然，在本公开的其他一些实施例中，还可以通过改变同一行的部分触控电极的弯折图形的弯折角度，来达到上述目的。
请参考图7，图7为本公开至少一个实施例的触摸屏的结构示意图，从图7中可以看出，同一行分区41中，奇数列分区41中的触控电极50的弯折图形的弯折角度为a，偶数列分区41中的触控电极50的弯折图形的弯折角度为b，从而使得不同分区中位于同一行的子电极线51不平行，不会向同一方向反射光线，从而在某一角度观察时，不会看到连续的明暗条纹。
也就是说，本公开实施例中，可以通过改变同一行的部分触控电极的弯折图形的弯折方向，或者改变部分同一行的部分触控电极的弯折图形的弯折角度，来避免出现明暗相间条纹的目的。当然，更复杂地，还可以通过同时 改变同一行的部分触控电极的弯折图形的弯折方向和弯折角度来达到上述目的，或者，改变同一行中一部分触控电极的弯折图形的弯折方向，同时改变同一行中另一部分的触控电极的弯折图形的弯折角度，来达到上述目的。
从图4、图5、图6所示的实施例中可以看出，本公开实施例的基板40上的多个分区41呈矩阵方式排列，位于同一行的相邻的两个分区中的触控电极的弯折图形的弯折方向不同。
从图7所示的实施例中可以看出，位于同一行的相邻的两个分区中的触控电极的弯折图形的弯折角度不同。
上述各实施例中，位于同一行的相邻的两个分区中的触控电极的弯折方向或弯折角度不同，从而可以避免出现横向的明暗相间的条纹。
在本公开的其他一些实施例中，为了避免出现纵向的明暗相间的条纹，可选地，位于同一列的相邻的两个分区中的触控电极的弯折图形的弯折方向或弯折角度设置为不同，请参考图8所示的实施例。图8所示的实施例中，位于同一列的相邻的两个分区41中的触控电极的弯折方向不同，并且，位于同一行的相邻的两个分区41中的触控电极的弯折图形的弯折方向也不同，该种设置可以同时避免横向和纵向的明暗个纹。
从图8中可以看出，位于同一行或同一列的多个分区中，第奇数个分区中的触控电极的弯折图形的弯折方向相同，第偶数个分区中的触控电极的弯折图形的弯折方向相同，且第奇数个分区中的触控电极与第偶数个分区中的触控电极的弯折图形的弯折方向不同。该种设置在避免横向或纵向明暗条纹的同时，整个基板上仅包括两种类型的触控电极，设置方式也较为简单。
上述各实施例中，每一分区41中包括至少一行至少一列触控电极50。如图4所示的实施例中，每一分区41包括一行三列触控电极51，如图5所示的实施例中，每一分区41包括两行两列触控电极51。
上述各实施例中，可选地，同一行和/或同一列的相邻两个分区中的触控电极轴对称设置。请参考图4、图5和图8，位于同一行的相邻的两个分区中的触控电极相对于径向线L对称设置。
可选地，上述实施例中的触摸屏为单层外挂式触摸屏。
单层外挂式触摸屏可以为互容式触摸屏，也可以为自容式触摸屏。
当本公开实施例的触摸屏为互容式触摸屏时，触控电极50包括驱动电极和感应电极，可选地，同一行和/或同一列的相邻两个分区41中，一个分区41设置驱动电极，一个分区41设置感应电极。
从图8所示的实施例可以看出，位于同一行相邻的两个分区中的触控电极的弯折图形向不同方向弯折，因而弯折方向不同的两相邻的触控电极之间会出现较大的空白区域，该空白区域如果规则性出现，则可以会引起新的可视问题，为了避免该问题，在本公开的一些实施例中，触摸屏还可以包括：补充图形，位于触控电极图形不同的相邻的两分区之间，用于填充触控电极图形不同的相邻的两分区之间的空白区域。请参考图9，本公开实施例的触摸屏还包括：补充图形60，位于触控电极图形不同的相邻的两分区之间，用于填充触控电极图形不同的相邻的两分区之间的空白区域。
上述各实施例中，同一行的多个分区中，第奇数个分区中的触控电极的形状相同，第偶数个分区中的触控电极的形状相同，其可以为上述实施例中的第一分区和第二分区，第一分区中的触控电极包括上述第一子电极线，第二分区中的触控电极包括上述第二子电极线，第一子电极线和第二子电极线位于同一行，且不平行。
本公开还提供一种触控装置，包括上述任一实施例所述的触摸屏。图10示出了本公开实施例提供的触控装置110，其包括一个根据上述任一实施例所述的触摸屏120。
以上所述是本公开的优选实施方式，应当指出，对于本技术领域的普通技术人员来说，在不脱离本公开所述原理的前提下，还可以作出若干改进和润饰，这些改进和润饰也应视为本公开的保护范围。
