图3是本发明所述触控基板的剖面图，图4为本发明所述触控基板的平面结构示意图。
如图3和图4所示，本发明提供一种触控基板，所述触控基板10具有触控区10a和围设在所述触控区10a的外围区10b。所述触控基板10包括第一金属层11、第二金属层12以及位于所述第一金属层11和所述第二金属层12之间的绝缘层13。
具体地，所述第一金属层11包括位于所述外围区10b的多组感应电极111，所述多个感应电极111被配置为至少用于感测所述触控基板的弯折动作并生成相应的感应信号。所述第二金属层12包括位于所述触控区10a的多组触控电极（图中未标示），所述触控电极被配置为至少用于感测所述触控基板上发生的触控操作并生成触控信号。
若一触控芯片分别与所述触控电极和所述感应电极111连接，则所述触控芯片被配置为至少用于依据所述感应信号确定弯折位置并对位于所述弯折位置处的所述触控电极的触控信号进行校正。
如图4所示，当所述触控基板10沿一固定轴AA’弯折(即处于固定曲率的弯曲模式)时，通过所述感应电极111可感测到第一弯折点(X1，Y1)和第二弯折点(X2，Y2)；当触控基板10分别沿两个固定轴(AA’和BB’)弯折时，通过所述感应电极111可感测到第一弯折点(X1，Y1)、第二弯折点(X2，Y2)、第三弯折点(X3，Y3)和第四弯折点(X4，Y4)。与此类推，当触控基板10多处弯折即处于全柔性模式时，通过所述感应电极111可识别多个弯折点位置信息，进而能依据所述弯折点位置信息，确定所述触控基板10的弯折位置。
可见，本发明所述触控基板10通过在所述第一金属层11的外围区10b设置多个感应电极111并通过所述触控芯片的配合，能识别弯折位置，进而能对弯折位置处的触控电极的触控信号进行校正，从而能解决因触控屏幕或触控显示面板的弯折造成的触控信号误判的问题。
图5为本发明所述第一金属层第一实施例平面结构示意图，图6是本发明所述第一金属层第二实施例平面结构示意图。以下将结合图3-图6对本发明所述触控基板10进行详细阐述。
如图3和图5所示，所述第一金属层11包括：位于所述感应区10a的电极桥点112、位于所述外围区10b的多个感应电极111以及与所述感应电极111连接的感应电极引线113。所述感应电极111被配置为至少用于感测所述触控基板10发生的弯折动作并依据所述弯折动作生成感应信号，所述感应电极引线113用于实现与所述感应电极111与所述触控芯片的连接，以将所述感应信号传送至所述触控芯片。
通过将所述感应电极111与所述电极桥点112同层设置，能够减少制作所述触控基板所需的掩膜板数量，减少制作触控基板10的构图工艺次数，缩短触控基板10的生产时间，降低触控基板10的制作成本。
具体地，所述感应电极111经配置构成用于感测弯折位置（或者称，弯折位置信号）感应电极区。
具体地，所述感应电极111经配置形成自容式感应电极（又叫自电容电极），以实现对触控基板10的弯折位置信号或弯折位置的感测。或者称，所述感应电极111在所述外围区10b形成能感测弯折动作和弯折位置的自容式感应电极区（或者称自容式感应区）。
通过利用自电容的原理，设置多个同层且相互绝缘的所述感应电极111，以所述感应电极111的感应电容作为感应信号，能检测所述触控基板10的弯折动作并能确定所述触控基板10发生弯折动作的弯折位置（即获取弯折位置信号）。例如，当触控基板10未发生弯折时，各所述感应电极111的电容值为一固定值(即所述初始电容值)；当触控基板10发生弯折时，弯折位置的处的所述感应电极111的电容值发生变化，所述触控芯片依据电容的变化确定弯折位置（或者称，所述触控芯片依据所述电容的变化获取相应的弯折位置信号）。
具体地，每一组所述感应电极111分别引接一接收电极信号，多组所述感应电极111共用一发射电极信号。
图7本发明所述感应电极第一实施例的平面结构示意图，图8本发明所述感应电极第二实施例的平面结构示意图，图9本发明所述感应电极第三实施例的平面结构示意图。以下将结合图7-图9将详细阐述本发明所述感应电极111的实施结构。
如图7、图8以及图9所示，每一所述感应电极111包括一接收电极1112和至少以发射电极1111,其中每一所述感应电极111的所述接收电极1112分别通过一感应电极引线113与所述触控芯片连接，多个感应电极组111的发射电极1111并联同一条感应电极引线113并通过上述感应电极引线113与所述触控芯片连接。
需要指出的是：图7、图8以及图9仅为本发明所述感应电极111的示意性设计方式。所述感应电极111的具体结构能依据需要进行进一步设计或更改。本发明所述触控基板10也并未限定每一所述感应电极111包括的发射电极1111的数量，例如但不限于，两个、三个或者四个。另外，本发明也并没有限定，一条感应电极引线113对应的感应电极111的数量。
具体地，所述感应电极111位于所述外围区10b。也就是说，所述感应电极111在所述第二金属层12上的正投影围绕在所述触控电极的外围。
进一步，所述感应电极111间距相等并与所述触控电极平行设置。
请参考图5，所述感应电极111环绕所述触控区10a的外围分布设置。也就是说，由所述感应电极111构成的自容式感应电极区环设在所述触控区10a的外围。在本实施例中，图5所示所述触控基板10可用于制作全柔性触控显示装置或全柔性触控显示面板。
如图6所示，本发明实施例还提供所述感应电极111分布位置的另一实施例。在图6所示实施例中，所述感应电极111对称设置于在触控区10a的一对相对侧边的外围。当所述触控基板10采用图6所示第一金属层结构时，所述触控基板10可用于制作固定转轴（固定曲率）的柔性屏。
需要指出的时，图5和图6仅示意性给出了感应电极111相对触控区10a分布位置的示意图。也就是说，在具体实施时，所述感应电极111或者由所述感应电极111形成的自容式感应区相对所述触控区10a的具体相对位置或方向，可以根据所述触控基板10或触控显示设备的柔性要求进行变更。
如图3、图5以及图6所示，所述多个电极桥点112位于所述触控区10a，用于实现所述触控电极的跨桥连接。通过将所述感应电极111与所述电极桥点112同层设置，能在进行电极桥点112的制作的同时制作所述感应电极111，不会造成面板制作工艺和掩膜板数量的增加。
具体地，所述电极桥点112阵列排布，并且所述电极桥点112的分布与所述触控电极相对应。

具体地，所述连接孔131内填充有导电材料并通过所述导电材料实现所述触控电极和所述电极桥点112的连接。在本实施例中，所述连接孔131在制备后续的第二金属层12的过程中会被用于制备所述第二金属层12的材料填充，即连接孔131内填充有第二金属层12的材料实现了所述触控电极和所述电极桥点112的连接，这种制备方式简单便捷易操作；在其它实施例中，也可以单独填充连接孔131，即所述连接孔内131的导电材料也可以与所述第二金属层12的材料不同，根据需要合理 设置即可。
在本实施例中，所述绝缘层13的材料选自SiNx或SiOx。在其它实施例中，所述绝缘层13还能选用其他有机或者无机透明的绝缘材料构成，根据需要合理设置即可。
如图3和图4所示，所述第二金属层12包括：多个触控电极和与所述感应电极同层且连接的触控电极引线123。其中，所述触控电极经配置以感测所述触控基板10上发生的触控操作并生成触控信号。或者称，所述触控电极用于感测触碰位置或触控位置。所述触控电极引线123用于实现所述触控电极与触控芯片的连接。
请续见图3，所述触控电极包括第一触控电极121和第二触控电极122，其中所述第一触控电极121或所述第二触控电极122通过所述连接孔131以及与所述连接孔131对应位置处的所述电极桥点113实现架桥连接。
进一步，所述触控电极为金属网格结构（Metal mesh）。具体地，所述第一触控电极121和所述第二触控电极122能分别采用金属网格结构。
通过采用电阻较小的金属网格结构的触控电极，能减小电阻电容延迟，提高触控电极的信号传输速度。
如图4所示，所述触控电极引线123位于所述外围区10b，用于实现所述触控电极与触控芯片的连接。具体地，所述第一触控电极121和所述第二触控电极122分别通过触控电极引线123与触控芯片连接，分别用于输送触控驱动信号和触控感应信号。
进一步，所述触控电极引线123在所述第一金属层11上的正投影覆盖所述感应电极111。例如，可以将所述感应电极111与所述第二金属层的12的触控引线区设置为上下对应。通过将调整所述感应电极111和触控引线123的对应位置关系，能避免所述感应电极111占用触控区10a，还避免额外增加外围区10b的宽度或面积，有利于实现窄边框设计。
在具体实施时，所述第二金属层12呈金属网格结构。所述第二金属层12采用材料为柔性金属。在具体实施时，所述第一金属层12还能选用其他具有导电性且抗弯折性能强的金属材质或导电材料。
