由于所述第二焊盘13布满所述绑定区域110，而所述第一焊盘21也对应所述绑定区域110，通过在所述第二焊盘13上设置胶材层（图中未标示），所述胶材层将所述柔性印刷电路板20绑定于所述显示面板10上。其中，所述第一连接子焊盘210与所述第二连接子焊盘130相对设置且电性连接，所述第一虚设子焊盘211与所述第二虚设子焊盘131相对设置且相互绝缘。
图示所述柔性印刷电路板20的所述第一连接子焊盘210为三段式，在其他实施例中可以为两段以上的多段式设计，此处不做限定。
在触控显示面板传统的窄边框设计中，有一种方法是将柔性印刷电路板的焊盘分为多段开口式的设计，但是由于中间空着的部分无法进行绑定膨胀系数补偿，绑定制程若采用一次性热压会产生焊盘两边的形变较大，如果分多次热压进行绑定，则时间成本较高。
本实施例通过在多段式的连接子焊盘之间的空置位置设置均匀的无电器特性的虚设子焊盘，采用焊盘对于绑定区域的全覆盖设计，实现了在绑定制程中提供稳定的膨胀系数，以及提供稳定的绑定环境，可以实现一次性绑定多个区域的连接子焊盘，大大降低了制程时间成本。同时连接子焊盘采用分段式设计，大大降低了信号走线在下边框所占的宽度，有利于实现触控显示面板的窄边框设计。由于焊盘对于绑定区域的全覆盖设计，有利于增大焊盘的附着力，提升其可靠性。
如图1B所示，所述柔性印刷电路板20在对应所述第一焊盘21的一侧依次包括弯曲区域22和非弯曲区域23，所述柔性印刷电路板20对应所述弯曲区域22的部分用于弯曲以将对应所述非弯曲区域23的部分弯折至所述显示面板10背部。所述柔性印刷电路板20在所述弯曲区域22间隔的设置有镂空部220。所述镂空部220的排列方向与所述第一虚设子焊盘211的排列方向相同，且所述镂空部220与所述第一虚设子焊盘211一一对应设置。所述镂空部220用于分散所述柔性印刷电路板20进行弯折时所述第一焊盘21所受的应力。所述镂空部220的边界可以延伸至所述第一焊盘21的边界位置。
当然，一所述第一虚设子焊盘211也可对应多个间隔的所述镂空部220，此处不做限定。
由于在所述柔性印刷电路板20的弯曲区域22中进行掏空设计，可以减小所述柔性印刷电路板20在弯折时所述弯曲区域22处受到的应力，避免在弯折中造成所述柔性印刷电路板20的损伤，大大增强了实际制作过程中的可靠性。
本申请还提供一种上述触控显示面板的绑定方法，如图2所示，所述方法包括以下步骤：
步骤S10，在所述显示面板的所述绑定区域涂覆胶材；
其中，所述胶材覆盖整个所述第二焊盘，所述胶材可以选用制程中常规的胶材。
步骤S20，将所述柔性印刷电路板设置有所述第一焊盘的一端对应所述绑定区域贴合于所述胶材上；
其中，由于所述第一焊盘与所述第二焊盘对应设置，且所述第一连接子焊盘与所述第二连接子焊盘对应设置，所述第一虚设子焊盘与所述第二虚设子焊盘对应设置，因此，只需完成所述第一焊盘与所述第二焊盘的对位，即可实现所述第一连接子焊盘与所述第二连接子焊盘的精准对位，有利于提高对位精准度以及节省制程时间。
步骤S30，采用热压设备通过热压工艺一次性将所述柔性印刷电路板绑定于所述显示面板上，其中，一所述第一连接子焊盘与对应一所述导电结合区域的所述信号引线电性连接。
其中，由于相邻两所述第一连接子焊盘之间填充有所述第一虚设子焊盘，以形成一体式的所述第一焊盘；相邻两所述第二连接子焊盘之间填充有所述第二虚设子焊盘，以形成一体式的所述第二焊盘；因此，在热压工艺中可以一次性的将所述柔性印刷电路板绑定于所述显示面板上，节省制程时间，而且还可以提高可靠性。
其中，所述第一虚设子焊盘与所述第二虚设子焊盘之间没有电性导通。
本申请提供的触控显示面板及绑定方法，通过在多段式的连接子焊盘之间的空置位置设置均匀的无电器特性的虚设子焊盘，采用焊盘对于绑定区域的全覆盖设计，实现了在绑定制程中提供稳定的膨胀系数，以及提供稳定的绑定环境，可以实现一次性绑定多个区域的连接子焊盘，大大降低了制程时间成本；同时有利于实现触控显示面板的窄边框设计，还有利于增大焊盘的附着力，提升其可靠性。另外，在柔性印刷电路板的弯曲区域进行掏空设计，减小了弯曲区域的应力，大大增强了实际制作过程中的可靠性。
综上所述，虽然本申请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申请，本领域的普通技术人员，在不脱离本申请的精神和范围内，均可作各种更动与润饰，因此本申请的保护范围以权利要求界定的范围为准。
