本发明实施例提供了一种显示装置，该显示装置包括触摸屏。请参照图1，图1为本发明实施例提供的触摸屏的结构示意图。触摸屏100包括柔性电路板101、基板102、源漏极层103、平坦层104、阳极层105、像素定义层106、触控电极层107、以及通孔108。
基板102包括薄膜晶体管、衬底等结构，用于承载上述柔性电路板101、源漏极层103以及平坦层104等结构。其中，该衬底可以为采用聚酰亚胺、聚碳酸酯、聚醚砜、聚对苯二甲酸乙二醇酯、聚萘二甲酸乙二醇酯、多芳基化合物等柔性材料组成的柔性衬底。
柔性电路板101设置在基板102上。柔性电路板101包括绑定区和非绑定区，柔性电路板10绑定区用于与基板102固定在一起，具体的，可以在柔性电路板101绑定区与基板102之间设置胶体层113，以使柔性电路板101与基板102固定在一起。其中，胶体层113中包括基材和导电粒子，基材可以为热固化树脂，导电粒子被包裹在基材中。当胶体层113受热压后，导电粒子释放，通过导电粒子分别与基板102中的导电衬底、柔性电路板101中的引脚端子电性连接，使柔性电路板101与基板102电性连接。如图1所示，柔性电路板101上还设置有驱动芯片112，该驱动芯片112用于控制触摸屏100快速且精确的呈现画面。
源漏极层103设置在基板102上。该源漏极层103可以由钛/铝/钛（Ti/Al/Ti）制成。该源漏极层103经图案化形成源漏极走线1031。如图1所示，在触摸屏100的非显示区域还具有弯曲区114，该弯曲区114用于将触摸屏100弯曲。该源漏极走线1031经弯曲区114与柔性电路板101的绑定区连接。位于弯曲区114上的源漏极走线1031可以设置为弯曲形状，以增加其受力面积，提高触摸屏100的耐弯折性能。
如图2所示，位于弯曲区114上的源漏极走线1031包括至少两个凸部a，这些凸部a依次连接。其中该凸部a的纵轴面可以为多边形、圆腰形或矩形等形状，也可以是上述两个或多个形状的组合。具体的，该多边形可以为轴对称多边形，也可以为不规则多边形。
位于弯曲区114上的源漏极走线1031包括至少两个镂空部b，该凸部a围绕该镂空部b设置，优选的，该镂空部b作为该凸部a的中心设置。相邻镂空部b可以邻接设置，也可以间隔设置。该镂空部b纵轴面可以是与该凸部a纵轴面匹配的形状。比如当凸部a纵轴面为六边形时，镂空部b纵轴面为四边形；当凸部a纵轴面为圆腰形时，镂空部b纵轴面为椭圆形。通过设置镂空部b，可以在触摸屏100弯曲时减少位于弯曲区114上的源漏极走线1031承受的应力，提高位于弯曲区114上的源漏极走线1031的耐弯曲性。
在一些实施例中，位于弯曲区114上的源漏极走线1031还包括至少一个凹部c，该凹部c、该凸部a邻接设置。该凹部c的纵轴面可以为矩形。该凹部c上也可以设置中空结构，以进一步提高源漏极走线1031的耐弯曲性。其中，该中空结构的纵轴面可以为与凹部c纵轴面匹配的矩形，也可以是圆形等形状。
在一些实施例中，如图4所示，位于弯曲区114上的源漏极走线1031可以设置成包含多条连接子线10311的形式，这样，如果其中一条连接子线10311发生断裂，其他连接子线10311可以确保该源漏极走线1031处于导通状态。优选的，该连接子线10311也可以设置成弯曲形状，具体的设置形式与上述单条源漏极走线类似，在此不再赘述。需要说明的是，如图4所示，位于同一条源漏极走线1031中的多条连接子像10311其弯曲形状可以相同，也可以不同，在此不做具体限定。
在一些实施例中，源漏极层103和基板102之间还包括缓冲层115，该缓冲层115可以用来减少触摸屏100弯曲时受到的应力。具体的，该缓冲层115可以由氮化硅SiNx、氧化硅SiOx等材料组成。
平坦层104设置在源漏极层103上，该平坦层104用于提供平坦表面。阳极层105设置在平坦层104上，像素定义层106设置在阳极层105上，触控电极层107设置在像素定义层106上。触控电极层107包括多条交叉分布的触控感应线和驱动感应线。具体的，触控电极层107设置在相邻像素的间隙区域上。在一些实施例中，触控电极层107中的触控感应线和驱动感应线，也可以设置为与上述源漏极走线1031相同的形状。
该触摸屏包括显示区和非显示区，通孔108位于非显示区，其包括第一通孔1081和第二通孔1082，其中第一通孔1081设置在平坦层104上，阳极层105通过第一通孔1081与源漏极层103电性连接。第二通孔1082设置在像素定义层106上，触控电极层107通过第二通孔1082与阳极层105连接。具体的，在源漏极层103上形成平坦层104后，先在平坦层104上打孔形成第一通孔1081，再在第一通孔1081内填充氧化铟锡ITO、金Au或氧化铟锌IZO等材料，并覆盖该平坦层104，形成阳极层105，即可使阳极层105与源漏极层103电性连接。
在一实施例中，该触摸屏100还包括保护层116和薄膜封装层117。该薄膜封装层117位于非显示区。具体的，该薄膜封装层117设置在平坦层104上。该薄膜封装层117可包括两层封装薄膜，以阻挡外界水汽和氧气对触摸屏100的侵蚀。其中该封装薄膜层117可以由氮化硅SiN x、二氧化硅SiO 2等材料组成。保护层116设置在像素定义层106上。由于像素定义层106采用光阻材料组成，该保护层116可以防止像素定义层106受后续刻蚀的损害。
同理的，可以先在阳极层105、平坦层104、薄膜封装层117上形成像素定义层106，再于像素定义层106上形成保护层116，然后在保护层116上打孔形成第二通孔1082，最后在第二通孔1082内填充金属材料，并部分覆盖该保护层116，形成触控电极层107，即可实现触控电极层107与阳极层105之间的电性连接。
上述触控电极层107先与阳极层105电性连接，再通过阳极层105作为桥梁，与源漏极层103电性连接的方式，避免了触控电极层107与源漏极层103通过金属走线直接电性连接时，因为二者之间高度差过高，导致金属走线容易断裂的问题。又源漏极层103与柔性电路板101上的绑定区电性连接，因此可以实现触控电极层107与柔性电路板101绑定区电性连接。
在一些实施例中，触摸屏100还包括偏光片109，该偏光片设置在触控电极层107上。如图1所示，触摸屏100还包括钝化层110和胶体层111，其中，钝化层110设置在触控电极层107上，胶体层111设置在钝化层110上，偏光片109设置在胶体层111上。偏光片109的边缘位于通孔108和弯曲区114之间。如图3所示，当触摸屏100弯曲时，其弯曲半径r为0.1-0.5毫米之间。触摸屏100弯曲的中心位置为d，该中心位置d位于偏光片109的边界内侧，这样可以减少触摸屏100中非显示区域的宽度，即减少触摸屏100边框的宽度，实现窄边框。
本发明的触摸屏及显示装置通过使源漏极层与阳极层电性连接，且使阳极层与触控电极层电性连接，不仅实现了源漏极层与触控电极层之间的电性连接，还提高了触摸屏的耐弯曲性。
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。
