具体实施方式
下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅仅是本发明一部分实施例，而不是全部的实施例。基于本发明中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都属于本发明保护的范围。
需要说明的是，在本发明实施例中使用的术语是仅仅出于描述特定实施例的目的，而非旨在限制本发明。在本发明实施例和所附权利要求书中所使用的单数形式的“一种”、“所述”和“该”也旨在包括多数形式，除非上下文清楚地表示其他含义。还应当理解，本文中使用的术语“和/或”是指并包含一个或多个相关联的列出项目的任何或所有可能组合。
请参阅图2，图2是本发明实施例提供的一种触控屏的结构示意图。本实施方式的触控屏100包括m个扫描块110。
每个扫描块110包括GOA(英文：Gate Driver On Array)级传电路113、 n条扫描线115以及至少一个TP(英文：touch panel)扫描模块117。其中，请一并参阅图3，GOA级传电路113的第一输入端用于输入STV信号，GOA级传电路113的第二输入端用于输入CK(英文：clock)信号，GOA级传电路113包括n个级联的GOA单元1131，GOA级传电路113中的第i级GOA单元1131用于对第i条扫描线115进行充电，第n条扫描线115连接至少一个TP扫描模块117。其中，不同扫描块110种的CK信号可以是单独的，也可以是复用的。
扫描时，向第1个扫描块110中的GOA级传电路113输入第1个STV信号，以启动对第1个扫描块110的扫描。在CK信号的配合下，第1个扫描块110中的GOA级传电路113控制依次完成第一个GOA单元1131对第一条扫描线115的充电至第n个GOA单元1131对第n条扫描线115的充电，以完成第1个扫描块110的图像信号的扫描。第1个扫描块110中的第n个GOA单元1131对第n条扫描线115充电完毕后，第n条扫描线115输出的信号驱动TP扫描模块117进行工作，以完成第1个扫描块110的触控信号的扫描。在第1个扫描块110扫描完毕后，向第2个扫描块110中的GOA级传电路113输入第2个STV信号，以启动对第2个扫描块110的扫描。在CK信号的配合下，第2个扫描块110中的GOA级传电路113控制依次完成第一个GOA单元1131对第一条扫描线115的充电至第n个GOA单元1131对第n条扫描线115的充电，以完成第2个扫描块110的图像信号的扫描。第2个扫描块110中的第n个GOA单元1131对第n条扫描线115充电完毕后，第n条扫描线115输出的信号驱动TP扫描模块117进行工作，以完成对第2个扫描块110的触控信号的扫描。依次类推，直到完成对第m个扫描块的扫描。
请一并参阅图4，采用上述的方法，可以将触控屏100分成多个扫描块110依次进行扫描，并在每个扫描块110的扫描时间中都有触控信号的扫描时间，所以，在一帧的扫描时间中可以有多个独立的触控信号的扫描时间。例如，一帧时间长度为16毫秒，触控屏100被分为4个扫描块110进行扫描，每个扫描块110的扫描时间为4毫秒。在每个扫描块110的扫描时间中，前3毫秒为显示信号的扫描时间，后1毫秒为触控信号的扫描时间。所以，在一帧的时间中，分别有4个独立的触控信号的扫描时间。由于在一帧的扫描时间中有多个 独立的触控信号的扫描时间，所以，即使在其中的一个触控信号的扫描时间的初始时刻测量的电容信号受到环境的影响，也不会对其他触控信号的扫描时间的触控信号检测造成影响。
可以理解的是，每个扫描块110的扫描时间可以设置为一样，也可以设置为不一样。类似地，不同扫描块110中的图像信号的扫描时间可以设置为一样，也可以设置为不一样。不同扫描块110中的触控信号的扫描时间可以设置为一样，也可以设置为不一样。
在另一个实施例中，触控屏100的结构不变，并且，每个扫描块110的大小一样。但是在扫描时，在同一时刻，向m个GOA级传电路113分别输入STV信号，以同时启动对m个扫描块的扫描。即在同一时刻，向第1个扫描块110中的GOA级传电路113输入第1个STV信号，向第2个扫描块110中的GOA级传电路113输入第2个STV信号，……，向第m个扫描块110中的GOA级传电路113输入第m个STV信号，以同时启动对第1个至第m个扫描块110的扫描。在CK信号的配合下，各个扫描块110中的GOA级传电路113控制依次完成第一个GOA单元1131对第一条扫描线115的充电至第n个GOA单元1131对第n条扫描线115的充电，以同时完成各个扫描块110的图像信号的扫描。在各个扫描块110同时对图像信号扫描完毕后，各个扫描块110中的第n条扫描线115同时输出信号驱动TP扫描模块117进行工作。
请一并参阅图5，采用上述的方法，可以将触控屏100分成多个扫描块110同时进行扫描，所以，扫描触控屏100的时间大大减少，扫描触控屏的触控信号的时间也大大减少。例如，触控屏100分成4个扫描块110同时进行扫描，则原来需要16毫秒才能完成触控屏100的扫描，其中，12毫秒为触控屏100的图像信号的扫描时间，4毫秒为触控屏100的触控信号的扫描时间。在划分扫描块110同时进行扫描后，只需要4毫秒就能完成触控屏100的扫描，其中，3毫秒为触控屏100的图像信号的扫描时间，1毫秒为触控屏100的触控信号的扫描时间，扫描触控屏100的时间大大减少，扫描触控屏的触控信号的时间也大大减少。所以，在相同的时间内，采用将触控屏100分成多个扫描块110同时进行扫描的方法能够提高触控信号的扫描次数，即使在其中的一次触控信号的扫描的初始时刻测量的电容信号受到环境的影响，也不会对其他次触控信 号的扫描的造成影响。
参阅图6，图6是本发明实施例提供的另一种触控屏的结构示意图。本实施方式的触控屏200包括：m个扫描块210。
每个扫描块210包括GOA级传电路213、n条扫描线215以及至少一个TP扫描模块217。其中，GOA级传电路213的结构与图3中所示的GOA级传电路113的结构相同。GOA级传电路213的第一输入端用于输入STV信号，GOA级传电路213的第二输入端用于输入第一CK信号，GOA级传电路213包括n个级联的GOA单元，GOA级传电路213中的第i级GOA单元用于对第i条扫描线215进行充电，TP扫描模块217的一端用于输入第二CK信号，TP扫描模块217的另一端用于输出TP扫描信号。其中，不同扫描块210种的第一CK信号以及第二CK信号可以是单独的，也可以是复用的。
扫描时，向第1个扫描块210中的GOA级传电路213输入第1个STV信号，以启动对第2个扫描块210的扫描。在第一CK信号的配合下，第1个扫描块210中的GOA级传电路213控制依次完成第一个GOA单元对第一条扫描线215的充电至第n个GOA单元对第n条扫描线215的充电，以完成第1个扫描块210的图像信号的扫描。第1个扫描块210中的第n个GOA单元对第n条扫描线215充电完毕后，向第1个扫描块210中的TP扫描模块217输入第二CK信号以启动第1个扫描块210中的TP扫描模块217对第1个扫描块210的触控信号进行扫描。在第1个扫描块210扫描完毕后，向第2个扫描块210中的GOA级传电路213输入第2个STV信号，以启动对第2个扫描块210的扫描。在第一CK信号的配合下，第2个扫描块210中的GOA级传电路213控制依次完成第一个GOA单元对第一条扫描线215的充电至第n个GOA单元对第n条扫描线215的充电，以完成第2个扫描块210的图像信号的扫描。第2个扫描块210中的第n个GOA单元对第n条扫描线215充电完毕后，向第2个扫描块210的TP扫描模块217输入第二CK信号以启动第2个扫描块210的TP扫描模块217对第2个扫描块210进行触控信号的扫描。依次类推，直到完成对第m个扫描块的扫描。
请一并参阅图4，采用上述的方法，可以将触控屏200分成多个扫描块210 依次进行扫描，并在每个扫描块210的扫描时间中都有触控信号的扫描时间，所以，在一帧的扫描时间中可以有多个独立的触控信号的扫描时间。例如，一帧时间长度为16毫秒，触控屏200被分为4个扫描块210进行扫描，每个扫描块210的扫描时间为4毫秒。在每个扫描块210的扫描时间中，前3毫秒为显示信号的扫描时间，后1毫秒为触控信号的扫描时间。所以，在一帧的时间中，分别有4个独立的触控信号的扫描时间。由于在一帧的扫描时间中有多个独立的触控信号的扫描时间，所以，即使在其中的一个触控信号的扫描时间的初始时刻测量的电容信号受到环境的影响，也不会对其他触控信号的扫描时间的触控信号检测造成影响。
可以理解的是，每个扫描块210的扫描时间可以设置为一样，也可以设置为不一样。类似地，不同扫描块210中的图像信号的扫描时间可以设置为一样，也可以设置为不一样。不同扫描块210中的触控信号的扫描时间可以设置为一样，也可以设置为不一样。
在另一个实施例中，触控屏200的结构不变，并且，每个扫描块210的大小一样。但是在扫描时，在同一时刻，向m个GOA级传电路213分别输入STV信号，以同时启动对m个扫描块的扫描。即在同一时刻，向第1个扫描块210中的GOA级传电路213输入第1个STV信号，向第2个扫描块210中的GOA级传电路213输入第2个STV信号，……，向第m个扫描块210中的GOA级传电路213输入第m个STV信号，以同时启动对第1个至第m个扫描块210的扫描。在第一CK信号的配合下，各个扫描块210中的GOA级传电路213控制依次完成第一个GOA单元对第一条扫描线215的充电至第n个GOA单元对第n条扫描线215的充电，以同时完成各个扫描块210的图像信号的扫描。在各个扫描块210同时对图像信号扫描完毕后，同时向各个扫描块210中的TP扫描模块217输入第二CK信号以启动各个扫描块210中的TP扫描模块217进行工作。
请一并参阅图5，采用上述的方法，可以将触控屏200分成多个扫描块210同时进行扫描，所以，扫描触控屏200的时间大大减少，扫描触控屏的触控信号的时间也大大减少。例如，触控屏200分成4个扫描块210同时进行扫描，则原来需要16毫秒才能完成触控屏200的扫描，其中，12毫秒为触控屏200 的图像信号的扫描时间，4毫秒为触控屏200的触控信号的扫描时间。在划分扫描块210同时进行扫描后，只需要4毫秒就能完成触控屏200的扫描，其中，3毫秒为触控屏200的图像信号的扫描时间，1毫秒为触控屏200的触控信号的扫描时间，扫描触控屏200的时间大大减少，扫描触控屏的触控信号的时间也大大减少。所以，在相同的时间内，采用将触控屏200分成多个扫描块210同时进行扫描的方法能够提高触控信号的扫描次数，即使在其中的一次触控信号的扫描的初始时刻测量的电容信号受到环境的影响，也不会对其他次触控信号的扫描的造成影响。
