具体实施方式
为使本公开的目的、技术方案和优点更加清楚，下面将结合附图对本公开实施方式作进一步地详细描述。
除非另作定义，此处使用的技术术语或者科学术语应当为本公开所属领域内具有一般技能的人士所理解的通常意义。本公开专利申请说明书以及权利要求书中使用的“第一”、“第二”以及类似的词语并不表示任何顺序、数量或者重要性，而只是用来区分不同的组成部分。同样，“一个”或者“一”等类似词语也不表示数量限制，而是表示存在至少一个。“连接”或者“相连”等类似的词语并非限定于物理的或者机械的连接，而是可以包括电性的连接，不管是直接的还是间接的。“上”、“下”、“左”、“右”等仅用于表示相对位置关系，当被描述对象的绝对位置改变后，则该相对位置关系也相应地改变。
在内嵌式触摸显示屏实现触摸功能时，需要对该内嵌式触摸显示屏输入触摸扫描信号以进行触摸扫描，以得到该内嵌式触摸显示屏上各个触摸单元的位置；在该内嵌式触摸显示屏实现显示功能时，需要通过对该内嵌式触摸显示屏输入显示扫描信号进行显示扫描，向该内嵌式触摸显示屏上的多个像素提供电能。实际应用中，由于该内嵌式触摸显示屏周围的环境会影响该触摸扫描的准确性，即影响得到该内嵌式触摸显示屏上各个触摸单元的位置的准确性。
相关技术中采用通过对该内嵌式触摸显示屏进行噪声扫描，获取该内嵌式触摸显示屏周围的环境对触摸扫描的影响值，并根据该影响值精确得到该内嵌式触摸显示屏上各个触摸单元的位置。示例地，所述噪声为妨碍获取该 内嵌式触摸显示屏上的各个触摸单元位置的因素。具体的，内嵌式触摸显示屏采用在单位扫描时间内，对该内嵌式触摸显示屏同时进行触摸扫描和显示扫描，得到该内嵌式触摸显示屏上各个触摸单元的位置，然后在该显示扫描和触摸扫描完成之后进行噪声扫描，根据该噪声扫描结果，精确该内嵌式触摸显示屏上各个触摸单元的位置。
由于该内嵌式显示屏的触摸扫描和显示扫描同时进行，所以在通过触摸扫描得到该内嵌式触摸显示屏上各个触摸单元的位置时，显示扫描发出的扫描信号会影响触摸扫描的准确性，且该内嵌式触摸显示屏的噪声扫描是在进行完显示扫描后进行的，因此，该噪声扫描无法获取该显示扫描信号对触摸扫描的影响值，从而无法精确的获取该内嵌式触摸显示屏上各个触摸单元的位置。
触摸显示装置可以包括触摸屏。触摸屏包括多个阵列排布的触摸单元，触摸屏上设置有多条横向设置的触摸驱动线Tx和多条纵向设置的触摸感应线Rx。一条触摸驱动线Tx对应一行触摸单元，一条触摸感应线Rx对应一列触摸单元。
如图1所示，本公开实施例提供了一种触摸屏00的结构示意图。该触摸屏00可以包括多个阵列排布的触摸单元001、多条阵列排布的Tx和多条阵列排布的Rx。示例性地，该多个Tx可以横向排布，该多个Rx可以纵向排布。图1中Tx的条数为6，Rx的条数为8。其中，一条Tx对应一行触摸单元001，一条Rx对应一列触摸单元001。
本公开实施例提供了一种噪声扫描方法，该噪声扫描方法可以用于触摸显示装置。如图2所示，该噪声扫描方法可以包括：
步骤201、对触摸屏进行触摸扫描；对触摸屏进行噪声扫描，触摸扫描与噪声扫描同时进行，其中，噪声扫描包括：对多条Tx进行噪声扫描，或，对多条Rx进行噪声扫描。
步骤202、根据触摸扫描的结果与噪声扫描的结果，得到触摸屏上各个触摸单元的位置。
综上所述，由于本公开实施例提供的噪声扫描方法中，在对触摸屏进行触摸扫描的同时对触摸屏进行噪声扫描，噪声扫描的过程中能够获取在触摸 扫描的过程中的所有噪声，即，当内嵌式触摸屏在触摸扫描的同时进行显示扫描时，噪声扫描能够获取显示扫描信号对触摸扫描的影响值，从而能够精确地得到触摸显示屏上各个触摸单元的位置，进而提高了触摸扫描的效果。
可选地，一条Tx对应一行触摸单元，一条Rx对应一列触摸单元，Tx与Rx耦合。对触摸屏进行触摸扫描可以包括：向第一Tx输入第一扫描信号，第一Tx为多条Tx中的任意一条Tx；获取第二扫描信号，第二扫描信号是第一Rx根据第一Tx上的第一扫描信号生成的，第一Rx为多条Rx中的任意一条Rx。
对多条Tx进行噪声扫描可以包括：在向第一Tx输入第一扫描信号时，对第一Tx进行噪声扫描，得到第一扫描信号的噪声。
在对多条Tx进行噪声扫描之后，噪声扫描方法还可以包括：对触摸屏进行附加噪声扫描，得到其他噪声。
触摸显示装置中预设有Tx标准信号的特征值，噪声扫描方法还可以包括：在向第一Tx输入第一扫描信号时，向与第一Tx相邻的第二Tx输入Tx标准信号；对第一Tx进行噪声扫描，得到第一扫描信号的噪声可以包括：获取第二Tx上的信号的特征值；计算第二Tx上的信号特征值与Tx标准信号特征值的差值；将差值作为第一扫描信号的噪声。需要说明的是，对第一Tx进行噪声扫描即通过向与第一Tx相邻的第二Tx输入Tx标准信号，然后收集第二Tx上的信号，计算第二Tx上的信号的特征值与Tx标准信号的特征值的差值，将差值作为第一扫描信号的噪声，完成对第一Tx上第一扫描信号的噪声的收集。
步骤202可以包括：根据第一扫描信号的噪声对第二扫描信号进行第一次噪声处理，得到第一次处理后的第二扫描信号；根据其他噪声对第一次处理后的第二扫描信号进行第二次噪声处理，得到第二次处理后的第二扫描信号；根据第一扫描信号以及第二次处理后的第二扫描信号，得到第一触摸单元的位置，第一触摸单元分别与第一Tx和第一Rx相对应。
对多条Rx进行噪声扫描可以包括：在获取第二扫描信号时，对第一Rx进行噪声扫描，得到第二扫描信号的噪声。
在一个实施例中，如图7所示，所述触摸屏可以分为显示区和非显示区， 触摸屏还包括基板。基板对应非显示区的位置上设置有一列参考电极组。所述一列参考电极组与Rx平行设置。基板上对应一列参考电极组的位置上设置有横向排布的多条附加Tx，多条Tx与多条附加Tx一一对应连接，多条Tx分为n个Tx组，n大于1，且为整数；一列参考电极组包括n个参考电极，每个参考电极与附加Tx耦合，n个Tx组与n个参考电极一一对应。例如，第一Tx位于第一Tx组中，第一Tx与第一附加Tx对应，第二Tx组与第一Tx组相邻，第二参考电极与第二Tx组相对应。且触摸显示装置中预设有Rx标准信号的特征值。
此时，对多条Rx进行噪声扫描方法还可以包括：在向第一Tx输入第一扫描信号时，向第二Tx组中的任意一条Tx输入Tx标准信号。对第一Rx进行噪声扫描，得到第二扫描信号的噪声可以包括：获取第二参考电极上的信号，第二参考电极上的信号为第二参考电极根据Tx标准信号受环境影响生成的感应信号，该信号即为第二扫描信号的噪声信号；计算第二参考电极上的信号的特征值与Rx信号的特征值的差值；将差值作为Rx接受到的有效信号。需要说明的是，Rx噪声扫描即为通过向第二Tx组中的任意一条Tx输入Tx标准信号，并收集第二参考电极上的信号，该信号即为第二扫描信号的噪声信号；然后，计算第二参考电极上的信号的特征值与Rx标准信号的特征值的差值，将差值作为Rx接受的有效信号，完成对Rx上第二扫描信号的噪声的收集和有效数据收集。
步骤202可以包括：根据第二扫描信号的噪声对第二扫描信号进行噪声处理，得到处理后的第二扫描信号；根据第一扫描信号以及处理后的第二扫描信号，得到第一触摸单元的位置，第一触摸单元分别与第一Tx和第一Rx相对应。
综上所述，由于本公开实施例提供的噪声扫描方法中，在对触摸屏进行触摸扫描的同时对触摸屏进行噪声扫描，噪声扫描的过程中能够获取在触摸扫描的过程中的所有噪声，即，当内嵌式触摸屏在触摸扫描的同时进行显示扫描时，噪声扫描能够获取显示扫描信号对触摸扫描的影响值，从而能够精确的获取触摸显示屏上各个触摸单元的位置，所以，提高了触摸扫描的效果。
本公开实施例提供了另一种噪声扫描方法，该噪声扫描方法可以用于触 摸显示装置，如图3所示，该噪声扫描方法可以包括：
步骤301、对触摸屏进行触摸扫描；对触摸屏进行噪声扫描，触摸扫描与噪声扫描同时进行，噪声扫描包括：对多条Tx进行噪声扫描。
示例性地，一条Tx对应一行触摸单元，一条Rx对应一列触摸单元，Tx与Rx耦合。具体地，Tx与Rx耦合是指Tx与Rx之间存在紧密配合与相互影响，当Tx上输入第一扫描信号时，Rx上能够根据该第一扫描信号生成相应的第二扫描信号。可以向第一Tx输入第一扫描信号，其中，第一Tx为多条Tx中的任意一条Tx。由于Tx与Rx耦合，所以多条Rx均能够根据Tx上的信号生成相应的信号。示例性地，在向第一Tx输入第一扫描信号之后，可以获取第二扫描信号，该第二扫描信号是第一Rx根据第一Tx上的第一扫描信号生成的，第一Rx为多条Rx中的任意一条Rx。
进一步地，该触摸显示装置中可以预设有Tx标准信号的特征值，该Tx标准信号的特征值为，在标准无噪声的环境下向Tx输入Tx标准信号后，在该Tx上获取的信号的特征值。在向该第一Tx输入第一扫描信号时，可以同时对该第一Tx进行噪声扫描，从而得到第一扫描信号的噪声。由于可以认为相邻的两个Tx上的噪声信号相同，因此，可以获取与该第一Tx相邻的第二Tx上的噪声，并将该第二Tx上的噪声作为第一Tx上的噪声。具体的，在步骤301中向该第一Tx输入第一扫描信号时，可以同时向与该第一Tx相邻的第二Tx输入Tx标准信号。例如，如图1所示，当向Tx1输入第一扫描信号时，可以同时向与Tx1相邻的Tx2输入Tx标准信号；当向Tx2输入第一扫描信号时，可以同时向与Tx2相邻的Tx1或Tx3输入Tx标准信号。由于该第一Tx与该第二Tx为相邻的两条Tx，所以，可以认为其他信号在第一Tx上产生的噪声与其他信号在该第二Tx上产生的噪声相同。可以获取第二Tx上信号的特征值，并计算第二Tx上信号特征值与Tx标准信号特征值的差值。该第二Tx上信号特征值与Tx标准信号特征值的差值为该第二Tx上的噪声，可以将该第二Tx上的噪声将作为第一扫描信号的噪声。
需要说明的是，对第一Tx进行噪声扫描即通过向与第一Tx相邻的第二Tx输入Tx标准信号，然后收集第二Tx上的信号，计算第二Tx上的信号的特征值与Tx标准信号的特征值的差值，将差值作为第一扫描信号的噪声，完 成对第一Tx上第一扫描信号的噪声的收集。
实际应用中，该内嵌式显示屏的触摸扫描和显示扫描同时进行，在对该内嵌式显示屏进行触摸扫描时，可以对该内嵌式触摸屏进行噪声扫描。具体地，可以对该内嵌式触摸屏上的多条Tx进行噪声扫描，实现了在进行噪声扫描的过程中，获取显示信号在多条Tx上产生的噪声的效果。
步骤302、对触摸屏进行附加噪声扫描，得到其他噪声。
具体地，该触摸屏所在的触摸显示装置上可以存储有标准感应信号，该标准感应信号为在标准无噪声的环境下，Rx根据Tx上输入的测试信号感应生成的。在对该触摸显示装置进行触摸扫描和噪声扫描完成之后，可以对该触摸屏进行附加噪声扫描，获取在触摸扫描的过程中的其他噪声(即在Rx根据Tx生成第二扫描信号的过程中该第二扫描信号上产生的噪声)。示例性地，可以向该触摸屏上的多条Tx输入测试信号，获取该触摸屏上的多条Rx上根据该测试信号生成的感应信号，并将该多条Rx上根据测试信号生成的感应信号与标准感应信号作差，将多条Rx上根据测试信号生成的感应信号与标准感应信号的差值作为其他噪声。需要说明的是，步骤302中的附加噪声扫描的具体做法可以参考相关技术中获取噪声的具体做法。
步骤303、根据触摸扫描的结果与噪声扫描的结果，得到触摸屏上各个触摸单元的位置。
示例性地，可以根据步骤301中获取的第二扫描信号所对应的第一扫描信号的噪声对该第二扫描信号进行第一次噪声处理，除去该第二扫描信号上该第一扫描信号所产生的噪声，得到第一次处理后的第二扫描信号。需要说明的是，根据噪声进行噪声处理的具体步骤可以参考相关技术中根据噪声进行噪声处理的具体步骤，本公开实施例对此不做赘述。然后，可以根据该第二扫描信号对应的其他噪声对第一次处理后的第二扫描信号进行第二次噪声处理，得到第二次处理后的第二扫描信号。具体地，由于步骤302中对该触摸屏进行了附加噪声扫描，获取了每个Rx上的其他噪声(即在第一Rx根据第一Tx生成第二扫描信号的过程中该第二扫描信号上产生的噪声)，因此，可以根据第二扫描信号对应的其他噪声，对第一次处理后的第二扫描信号进行第二次噪声处理，除去在第一Rx根据第一Tx生成第二扫描信号的过程中 该第二扫描信号上的噪声，得到第二次处理后的第二扫描信号。
进一步地，可以根据该第一扫描信号和该第二次处理后的第二扫描信号得到该触摸屏上的一个位置，并确定该位置为第一Tx和第一Rx对应的第一触摸单元的位置。如图4所示，若第一Tx为Tx1，第一Rx为Rx2，在该Tx1上输入第一扫描信号，该Rx2可以根据该Tx1上的第一扫描信号生成第二扫描信号，在对该第二扫描信号依次进行第一次噪声处理和第二次噪声处理之后，得到了第二次处理后的第二扫描信号。然后可以根据该第一扫描信号和该第二次处理后的第二扫描信号得到触摸屏上的一个位置，并确定该位置为Tx1和Rx2对应的第一触摸单元的位置，即该第一Tx和该第一Rx对应的第一触摸单元的位置为该触摸屏00上的第一行、第二列所对应触摸单元001的位置。
进一步地，如图5所示，当触摸屏00为自容式触摸屏时，即触摸屏00上设置有多个阵列排布的触摸单元001，且每个触摸单元001对应该触摸屏00上的一个位置，每个触摸单元001上设置有一条触摸线Mx。例如，该触摸屏00上第一行第一列的触摸单元U对应的触摸线为Mx1，该触摸屏00上第一行第二列的触摸单元V对应的触摸线为Mx2，在对该触摸单元U进行触摸扫描的同时也可以向与触摸单元U相邻的触摸单元V的触摸线Mx2输入标准输入信号，并获取该Mx2上的信号的特征值，将该Mx2上的信号特征值与标准输出信号特征值的差值作为该触摸单元U对应的触摸线Mx1上的噪声。在对该触摸单元U进行触摸扫描时，向该触摸单元U对应的触摸线Mx1上输入第一扫描信号，该触摸单元U对应的触摸线Mx1根据该第一扫描信号生成第二扫描信号，然后可以根据该触摸单元U对应的触摸线Mx1上的噪声对该第二扫描信号进行噪声处理，得到处理后的第二扫描信号，并根据该第一扫描信号和该处理后的第二扫描信号得到该触摸屏00上的一个位置，并确定该位置为该触摸单元U的位置。需要说明的是，该触摸屏00上其他触摸单元001位置的确定方法可以参考触摸单元U位置的确定方法，本公开实施例在此不做赘述。
综上所述，由于本公开实施例提供的噪声扫描方法中，在对触摸屏进行触摸扫描的同时对触摸屏进行噪声扫描，噪声扫描的过程中能够获取在触摸 扫描的过程中的所有噪声，即，当内嵌式触摸屏在触摸扫描的同时进行显示扫描时，噪声扫描能够获取显示扫描信号对触摸扫描的影响值，从而能够精确的获取触摸显示屏上各个触摸单元的位置，所以，提高了触摸扫描的效果。
本公开实施例提供了又一种噪声扫描方法，该噪声扫描方法可以用于触摸显示装置，如图6所示，该噪声扫描方法可以包括：
步骤501、对触摸屏进行触摸扫描；对触摸屏进行噪声扫描，触摸扫描与噪声扫描同时进行，噪声扫描包括：对多条Rx进行噪声扫描。
一条Tx对应一行触摸单元，一条Rx对应一列触摸单元，Tx与Rx耦合，具体地，Tx与Rx耦合是指Tx与Rx之间存在紧密配合与相互影响。当Tx上输入第一扫描信号时，Rx上能够根据该第一扫描信号生成相应的第二扫描信号。可以向第一Tx输入第一扫描信号，其中，第一Tx为多条Tx中的任意一条Tx。由于Tx与Rx耦合，所以多条Rx均能够根据Tx上的信号生成相应的信号。示例性地，在向第一Tx输入第一扫描信号之后，可以获取第二扫描信号，该第二扫描信号是第一Rx根据第一Tx上的第一扫描信号生成的，第一Rx为多条Rx中的任意一条Rx。
进一步地，基板对应非显示区的位置上设置有一列参考电极组，一列参考电极组与Rx平行设置，基板上对应一列参考电极组的位置上设置有横向排布的多条附加Tx，多条Tx与多条附加Tx一一对应连接。多条Tx分为n个Tx组，n大于1，且为整数；一列参考电极组包括n个参考电极，每个参考电极与附加Tx耦合，n个Tx组与n个参考电极一一对应。例如，第一Tx位于第一Tx组中，第一Tx与第一附加Tx对应，第二Tx组与第一Tx组相邻，第二参考电极与第二Tx组相对应。触摸显示装置中预设有Rx标准信号的特征值。该Rx标准信号的特征值为，在标准无噪声的环境下，向该第一Tx输入Tx标准信号，第一Rx根据该Tx标准信号生成的。
在向该第一Tx输入第一扫描信号时，可以同时向第二Tx组中的任意一条Tx输入Tx标准信号。在获取第二扫描信号时，可以对第一Rx进行噪声扫描，得到第二扫描信号的噪声。具体地，可以获取第二参考电极上的信号，该信号即为第二扫描信号的噪声信号，该第二参考电极上的信号是该第二参考电极根据该Tx标准信号受环境影响生成的感应信号。在获取该第二参考电 极上的信号后，可以提取该第二参考电极上的信号的特征值，然后计算第二参考电极上的信号的特征值与Rx信号的特征值的差值；将差值作为Rx接受到的有效信号。
示例性地，如图7所示，本公开实施例提供了另一种触摸屏00，触摸显示装置可以包括触摸屏00，该触摸屏00可以分为显示区X和除显示区X以外的非显示区Y，触摸屏00包括基板(图7中未示出)。图7中共有6条Tx，分别为Tx1、Tx2、Tx3、Tx4、Tx5和Tx6。相应的，基板对应非显示区Y的位置上设置有横向排布的6条附加Tx，6条Tx与6条附加Tx一一对应连接。将6条Tx划分为3个Tx组。具体地，将Tx1和Tx2划为Tx组1，将Tx3和Tx4划为Tx组2，将Tx5和Tx6划为Tx组3。基板对应非显示区Y的位置上设置有一列参考电极组，一列参考电极组包括3个参考电极Rf，分别为Rf1、Rf2和Rf3。所述一列参考电极组与Rx平行设置，一列参考电极组在基板上的投影与多条附加Tx相交，每个参考电极Rf与对应的附加Tx耦合，且n个Tx组与n个参考电极Rf一一对应。具体地，Rf1与Tx组1相对应，Rf2与Tx组2相对应，Rf3与Tx组3相对应。
若第一Tx为Tx1，Tx1位于Tx组1中，Tx1与附加Tx1对应，Tx组2与Tx组1相邻，Rf2与Tx组2相对应。在对该Tx1进行触摸扫描时，可以向该Tx1输入第一扫描信号，该Rx1能够根据该Tx1上的第一扫描信号生成第二扫描信号，在该Rx1生成该第二扫描信号后，可以获取该Rx1生成的第二扫描信号。进一步地，由于Tx组1与Tx组2为两个相邻的Tx组，Rx根据Tx组1中的任意一个Tx生成的第二扫描信号上的噪声与Rx根据Tx组2中的任意一个Tx生成的第二扫描信号上的噪声相同，所以，在向该Tx1输入第一扫描信号时，可以同时向Tx组2中的Tx3输入Tx标准信号。在获取该Rx1生成的第二扫描信号时，可以对Rx1进行噪声扫描，得到第二扫描信号的噪声。具体地，可以获取Rf2上的信号，该Rf2上的信号为Rf2根据该Tx3上的Tx标准信号生成的，该信号即为第二扫描信号的噪声信号。在获取该Rf2上的信号后，可以提取Rf2上的信号的特征值，然后计算Rf2上的信号的特征值与Rx标准信号的特征值的差值，并将该差值作为Rx接受到的有效信号。
需要说明的是，对第一Rx进行噪声扫描即通过向第二Tx组中的任意一条Tx输入Tx标准信号，并收集第二参考电极上的信号，计算第二参考电极上的信号的特征值与Rx标准信号的特征值的差值，将差值作为第二扫描信号的噪声，完成对第一Rx上第二扫描信号的噪声的收集。
步骤502、根据触摸扫描的结果与噪声扫描的结果，得到触摸屏上各个触摸单元的位置。
根据第二扫描信号的噪声对第二扫描信号进行噪声处理，得到处理后的第二扫描信号。具体地，由于步骤501中对该触摸屏进行了噪声扫描，获取了第二扫描信号的噪声，因此，可以根据步骤501中获取的第二扫描信号的噪声，对该第二扫描信号进行噪声处理，除去第二扫描信号上的所有噪声(包括该第一扫描信号所产生的噪声以及在第一Rx根据第一Tx生成第二扫描信号的过程中该第二扫描信号上产生的噪声)，得到处理后的第二扫描信号。
进一步地，可以根据该第一扫描信号和该处理后的第二扫描信号得到该触摸屏上的一个位置，并确定该位置为第一Tx和第一Rx对应的第一触摸单元的位置。如图4所示，若第一Tx为Tx1，该第一Rx为Rx2，在该Tx1上输入第一扫描信号，该Rx2根据该Tx1上的第一扫描信号生成第二扫描信号，在根据该第二扫描信号上的噪声对该第二扫描信号进行噪声处理之后，得到了处理后的第二扫描信号。然后可以根据该第一扫描信号和该处理后的第二扫描信号得到触摸屏上的一个位置，并确定该位置为Tx1和Rx2对应的第一触摸单元的位置，即该第一Tx和该第一Rx对应的第一触摸单元的位置为该触摸屏00上的第一行、第二列所对应触摸单元001的位置。
可选地，在步骤502之前，对该触摸屏进行噪声扫描时，还可以采用上一实施例中的步骤301和步骤302中对触摸屏进行噪声扫描的方法获取噪声。在步骤502中，还可以根据步骤501中获取的噪声以及采用上一实施例中的步骤301和步骤302中对触摸屏进行噪声扫描的方法获取的噪声，对触摸屏进行噪声处理。具体地，可以首先参考步骤303中根据步骤301和步骤302中对触摸屏进行噪声扫描的方法获取的噪声对触摸屏进行噪声处理，之后参考步骤502中根据步骤501中获取的噪声对触摸屏进行进一步地噪声处理，得到该触摸屏上触摸单元的位置。可选地，也可以首先参考步骤502中根据 步骤501中获取的噪声对触摸屏进行进一步地噪声处理，之后参考步骤303中根据步骤301和步骤302中对触摸屏进行噪声扫描的方法获取的噪声对触摸屏进行噪声处理，得到该触摸屏上触摸单元的位置。
进一步地，如图5所示，当触摸屏00为自容式触摸屏时，即触摸屏00上设置有多个阵列排布的触摸单元001，且每个触摸单元001对应该触摸屏00上的一个位置，每个触摸单元001上设置有一条触摸线Mx。例如，该触摸屏00上第一行第一列的触摸单元U对应的触摸线为Mx1，该触摸屏00上第一行第二列的触摸单元V对应的触摸线为Mx2，在对该触摸单元U进行触摸扫描的同时也可以向与触摸单元U相邻的触摸单元V的触摸线Mx2输入标准输入信号，并获取该Mx2上的信号的特征值，将该Mx2上的信号特征值与标准输出信号特征值的差值作为该触摸单元U对应的触摸线Mx1上的噪声。在对该触摸单元U进行触摸扫描时，向该触摸单元U对应的触摸线Mx1上输入第一扫描信号，该触摸单元U对应的触摸线Mx1根据该第一扫描信号生成第二扫描信号，然后可以根据该触摸单元U对应的触摸线Mx1上的噪声对该第二扫描信号进行噪声处理，得到处理后的第二扫描信号，并根据该第一扫描信号和该处理后的第二扫描信号得到该触摸屏00上的一个位置，并确定该位置为该触摸单元U的位置。需要说明的是，该触摸屏00上其他触摸单元001位置的确定方法可以参考触摸单元U位置的确定方法，本公开实施例在此不做赘述。
综上所述，由于本公开实施例提供的噪声扫描方法中，在对触摸屏进行触摸扫描的同时对触摸屏进行噪声扫描，噪声扫描的过程中能够获取在触摸扫描的过程中的所有噪声，即，当内嵌式触摸屏在触摸扫描的同时进行显示扫描时，噪声扫描能够获取显示扫描信号对触摸扫描的影响值，从而能够精确的获取触摸显示屏上各个触摸单元的位置，所以，提高了触摸扫描的效果。
