需要说明的是，本说明书中的各个实施例均采用递进的方式描述，每个实 施例重点说明的都是与其它实施例的不同之处，各个实施例之间相同相似的部分互相参见即可。对于装置实施例而言，由于其与方法实施例基本相似，所以描述的比较简单，相关之处参见方法实施例的部分说明即可。
通过上述实施例的描述，本发明具有以下优点：
由于所述薄膜晶体管电连接驱动电路，所述驱动电路电连接所述印刷电路板，第一触摸电极通过第一引线连接到所述印刷电路板，所述第二触摸电极通过第二引线连接到所述印刷电路板，从而，相对现有技术，不需要由于薄膜晶体管、第一触摸电极、第二触摸电极而设置两个印刷电路板，从而可以节省了成本，而且，制程也相对现有技术简单。
以上所揭露的仅为本发明较佳实施例而已，当然不能以此来限定本发明之权利范围，因此依本发明权利要求所作的等同变化，仍属本发明所涵盖的范围。
