作为一个可选实施例，所述触控显示屏还包括显示模组，所述触控单元位于所述显示模组上；
所述金属区域1和所述金属线2在所述显示模组上的正投影位于所述显示模组的非发光像素区域。
也就是说，该触控单元叠设在该显示模组上，以实现用户的触控操作功能，具体的，为了避免触控单元的金属区域1和金属线2遮挡该显示模组的发光像素区域，本申请实施例将该金属区域1和该金属线2设置在其正投影位于该显示模组的非发光像素区域的位置。
本申请实施例的电子设备，通过将用于调节触控单元的传输电极和接收电极的互容量的多个金属区域中的至少一个金属区域与天线芯片电连接，使 得该至少一个金属区域兼具天线电极的功能，实现了金属区域的复用，从而无需增加额外的天线电极即可实现天线与触控单元的集成，避免了天线电极占用传输电极和/或接收电极的空间导致触控功能受限的问题；通过将金属区域和连接金属区域的金属线在电子设备的显示模组上的正投影位于该显示模组的非发光像素区域，使得电子设备的显示区域不会由于天线与触控单元的集成而变小，从而不会影响用户的使用体验。
如图5所示，为本申请实施例的触控显示屏的制备方法的步骤示意图，其中，所述触控显示屏包括多个触控单元，该触控显示屏的制备方法包括：
步骤501：制备触控单元，所述触控单元包括传输电极、接收电极和多个金属区域；
顾名思义，触控单元具有触控功能，而触控单元一般为互容触控式，即：触控单元需要包括两组触控电极(传输电极和接收电极)，由于触控单元的触控性能与触控电极的有效面积相关，因此，触控单元中需要设置用于调节触控电极的有效面积的金属区域。
步骤502：通过邦定工艺，将至少一个所述金属区域与电子设备的天线芯片电连接。
需要说明的是，“邦定”是芯片生产工艺中一种打线的方式，一般用于封装前将芯片内部电路用金线或铝线与封装管脚或线路板镀金铜箔连接。本步骤中，则是将金属区域与芯片管脚通过打线的方式连接，从而使得两者能够电连接，实现信号传输，使得金属区域具有天线电极的功能。
本申请实施例的触控显示屏的制备方法，通过在所述触控单元内间隔设置多个金属区域，并将至少一个所述金属区域与所述天线芯片电连接，使得所述金属区域具有天线电极的功能，实现了天线与触控模组的集成，且不占用触控模组的触控传感器的空间，从而不会给触控显示屏的的触控性能带来局限性，也不会减小触控显示屏的显示区域的面积。
可选的，所述触控显示屏还包括显示模组；
步骤501，所述制备触控单元，包括：
制备第一金属层，所述第一金属层上间隔设有多个所述金属区域；其中，所述第一金属层位于所述显示模组的上方。
本步骤可以通过掩膜工艺制备该第一金属层，具体的，通过第一掩膜版定义该金属区域的位置，从而实现利用该第一掩膜版制备该第一金属层。
进一步的，步骤501，所述制备触控单元，还包括：
制备第一保护层，所述第一保护层上设有多个过孔；具体的，通过第二掩膜版定义过孔，并利用该第二掩膜版制备该第一保护层。
制备第二金属层，所述第二金属层包括多个金属线；具体的，通过第三掩膜版定义金属线，并利用该第三掩膜版制备该第二金属层。
其中，所述第一保护层位于所述第二金属层和所述第一金属层之间，所述过孔在所述第一金属层上的正投影位于所述金属区域上，所述过孔在所述第二金属层上的正投影位于所述金属线上。
更进一步的，步骤501，所述制备触控单元，还包括：
在显示模组上制备平坦化层；其中，所述第一金属层、所述第一保护层和所述第二金属层位于所述平坦化层的上方，所述金属线和所述金属区域在所述显示模组上的正投影位于所述显示模组的非像素显示区域。
具体的，通过第四掩膜版定义触控区域，并在该触控区域中制备该平坦化层。其中，该触控区域的面积大于该显示模组的显示区域。
更进一步的，步骤501，所述制备触控单元，还包括：
制备第二保护层；其中，所述第二保护层位于所述第一金属层、所述第一保护层和所述第二保护层的上方。
需要说明的是，本申请实施例中，触控单元包括：平坦化层、第一保护层、第二保护层、第一金属层和第二金属层；其中，平坦化层位于触控单元靠近显示模组的一侧，第二保护层位于与平坦化层相对的一侧，第一保护层、第一金属层和第二金属层位于平坦化层和第二保护层之间。
下面，具体说明本申请实施例的触控单元的制备过程：
制备过程一：
A)在显示模组上确定触控区域，并在该触控区域上制备平坦化层；
B)在平坦化层上制备第一金属层，第一金属层包括金属区域；
C)在第一金属层上制备第一保护层；
D)在第一保护层上制备第二金属层，第二金属层包括金属线；
E)在第二金属层上制备第二保护层。
制备过程二：
a)在显示模组上确定触控区域，并在该触控区域上制备平坦化层；
b)在第一保护层上制备第二金属层，第二金属层包括金属线；
c)在第二金属层上制备第一保护层；
d)在平坦化层上制备第一金属层，第一金属层包括金属区域；
e)在第二金属层上制备第二保护层。
本申请实施例的触控显示屏的制备方法，通过依次制备触控单元的平坦化层、第一金属层/第二金属层、第一保护层、第二金属层/第一金属层、第二保护层，然后，将金属线通过打线的方式与天线芯片连接，使得所述金属区域兼具天线电极的功能和电容量调节的功能，实现了天线与触控模组的集成，且不占用触控模组的触控传感器的空间，从而不会给触控显示屏的触控性能带来局限性，也不会减小触控显示屏的显示区域的面积。
