目前柔性触摸屏最常使用的是外挂式电容触摸屏，选用柔性塑料做基材，在其上制作透明导电膜电极线路，然后通过贴合工艺贴附到柔性显示屏上应用。而现在最常用的透明电极材料是ITO，其制备工艺相对成熟，但其脆性较高，柔性显示设备在使用过程中进行弯折时，ITO透明感应电极很容易产生应力集中而出现裂纹并扩展，导致触摸性能不良。
综上所述，现有技术的柔性触摸屏，耐弯折性较差，经常弯折部位的电极受应力影响而导致线路损坏，影响产品品质，因此，需要提供一种耐弯折性较好的柔性触摸屏。
 技术问题
本发明提供一种柔性触摸屏结构，通过改变电极引线分布结构，能够避免电极引线因重复弯折导致线路受损，以解决现有柔性触摸屏经常弯折部分的电极引线受弯曲应力影响而损坏，进而影响触控效果的技术问题。

例如，在所述柔性基底101表面设置第一驱动电极105、第二驱动电极106、第一感应电极107及第二感应电极108；其中，所述第一驱动电极105与第二驱动电极106位于所述柔性基底101的同侧，并且，所述第一驱动电极105与所述第二驱动电极106相对位于所述弯折区104的两侧，同理，所述第一感应电极107与所述第二感应电极108位于所述柔性基底101的相对另一侧，并且，所述第一感应电极107与所述第二感应电极108相对位于所述弯折区104的两侧。

实施例二
如图2所示，本发明的柔性触摸屏，包括柔性基底201，其表面界定有第一视窗区202、第二视窗区203及位于所述第一视窗区202、第二视窗区203之间的弯折区204，所述第一视窗区202、第二视窗区203内制备有驱动电极层与感应电极层；所述驱动电极层制备于所述柔性基底201的一侧，所述感应电极层制备于所述柔性基底201的另一侧。

本发明还提供一种柔性触摸显示屏，本优选实施例的柔性触摸显示屏包括如图1和2所示的前述实施例中的柔性触摸屏，在此不再赘述。
本发明的有益效果为：相较于现有的柔性触摸屏，本发明的柔性触摸屏，电极及电极引线避开触摸屏的弯折处排布，避免电极引线被弯折，进而降低触摸屏弯曲应力致电极引线受损，进而延长柔性触摸屏的使用寿命；解决了现有技术的柔性触摸屏，耐弯折性较差，经常弯折部位的电极引线受弯曲应力影响而导致线路损坏，影响产品品质的技术问题。
综上所述，虽然本发明已以优选实施例揭露如上，但上述优选实施例并非用以限制本发明，本领域的普通技术人员，在不脱离本发明的精神和范围内，均可作各种更动与润饰，因此本发明的保护范围以权利要求界定的范围为准。
