以下对处理器103如何判断触摸对象在触摸面板101进行触摸时的触摸位置进行说明。
例如，请参阅图4，图4为触摸对象在触摸面板的触摸位置为L时的简单示意图，触摸位置L在第二感测电极131、第一感测电极112、第二感测电极132上。
若触摸对象在第二感测电极131上的触摸面积与在第二感测电极132上的触摸面积相同，所述触摸面积为触摸对象与触摸面板101的接触面积，处理器103可检测到第二感测电极131与第二感测电极132的电容变化相同，处理器103即可判断触摸位置L在第二感测电极131与第二感测电极132中间。若触摸对象在第二感测电极131上的触摸面积大于在第二感测电极132上的触摸面积，处理器103根据第二感测电极131与第二感测电极132的电容变化，即可判断触摸位置L在Y方向(图4中箭头方向)上偏向第二感测电极131。
又如，触摸位置仅在第二感测电极131及第一感测电极112上。若处理器103检测到第二感测电极131及第一感测电极112的电容值变化值一致，处理器103即可判断出触摸位置在第二感测电极131及第一感测电极112之间；若处理器103检测到第二感测电极131电容变化值大于第一感测电极112的电容变化值，即在Y方向上触摸位置偏向第二感测电极131。具体数值可通过其不同电容变化值与坐标位置之间的相应关系算出。
请参阅图5，图5为本公开第二实施方式提供的触摸装置的结构框图。触摸装置200包括触摸面板201及与触摸面板201电性连接的处理器203。请参阅图6，图6为本公开第 二实施方式提供的触摸面板的叠层结构示意图。触摸面板201包括层叠设置的触摸层30及压感导体层50。本实施方式中，触摸层30与触摸面板201的最外侧相邻设置。触摸层30用于响应用户的触摸而产生第一触摸信号。压感导体层50用于响应用户的触摸而产生第二触摸信号。本实施方式中，压感导体层50与触摸层30共同形成电容式压感结构，即触摸面板201受力形变时，会引起触摸面板201对应位置处的压感导体层50与触摸层30之间的电容变化，使得压感导体层50产生第二触摸信号。在其他实施方式中，压感导体层50可以电阻式压感结构，或者压感导体层50可以为自电容式压感结构。
请参阅图7，图7为本公开第二实施方式提供的触摸层的部分平面示意图。触摸层30包括多个第一感测电极31(图7中仅示例性地示出5个)、多个第二感测电极33(图7中仅示例性地示出4个)、一个第一布线35及多个第二布线37(图7中仅示例性地示出2个)。
多个第一感测电极31与多个第二感测电极33同层设置。多个第一感测电极31间隔排列，相邻的两个第一感测电极31之间设一个第二感测电极33，多个第二感测电极33间隔排列，相邻的两个第二感测电极33之间设一个第一感测电极31。换而言之，第一感测电极31与第二感测电极33相互交替设置。
本实施方式的触摸层30与第一实施方式提供的触摸层10结构相似，不同在于，触摸层30还包括多个电极单元，每个电极单元包括两个第二感测电极33，同个电极单元的第二感测电极33与同一个第二布线37电性连接。
同个电极单元的两第二感测电极33间至少设有其他电极单元的一个第二感测电极33，避免触摸盲点，提高触摸面板201的可靠性。即每两个第二感测电极33组成一个电极单元。
多个第一感测电极31包括第一感测电极311、第一感测电极312、第一感测电极313、第一感测电极314与第一感测电极315；多个第二感测电极33包括第二感测电极331、第二感测电极332、第二感测电极333、第二感测电极334。第一感测电极311、第二感测电极331、第一感测电极312、第二感测电极332、第一感测电极313、第二感测电极333、第一感测电极314、第二感测电极334及第一感测电极315依次排列。
第二感测电极331与第二感测电极333组成一个电极单元，第二感测电极332与第二感测电极334组成一个电极单元。第二布线37包括第二布线371及第二布线373。其中，第二感测电极331与第二感测电极333与同个第二布线371电性连接，第二感测电极332与第二感测电极334同个第二布线373电性连接。
由于同个电极单元的两个第二感测电极33与同个第二布线37电性连接，避免每个第二感测电极33通过单个布线连接，从而减少布线的数量，能够有效减小触摸面板201的边框区的宽度，进一步有利于触摸面板201的无框化及全屏化发展。
图8为压感导体层的部分平面示意图。压感导体层50包括同层设置的多个压感通道51。 每个第一感测电极31和每个第二感测电极33分别与一个压感通道51位置对应。即每个第一感测电极31与对应的压感通道51具有触摸面板201上的相同的位置坐标，每个第二感测电极33与对应的压感通道51具有触摸面板201上的相同的位置坐标。
多个压感通道51包括压感通道511、压感通道512、压感通道513、压感通道514、压感通道515、压感通道516、压感通道517、压感通道518及压感通道519。压感通道511对应第一感测电极311的位置，压感通道512对应第二感测电极331的位置，压感通道513对应第一感测电极312的位置，压感通道514对应第二感测电极332的位置，压感通道515对应第一感测电极313的位置，压感通道516对应第二感测电极333的位置，压感通道517对应第一感测电极314的位置，压感通道518对应第二感测电极334的位置，压感通道519对应第一感测电极315的位置。
由于同个电极单元的两个第二感测电极33与同个第二布线37电性连接，当触摸对象触摸在触摸面板201的某个位置时，处理器203会得出两个触摸位置：第一位置坐标及第二位置坐标。例如图9，当触摸对象触摸第二感测电极331、第一感测电极312、第二感测电极332时，处理器203获取第一位置坐标M1、第二位置坐标M2，其中第一位置坐标M1为实际触摸位置，第二位置坐标M2为虚拟触摸位置，即处理器203无法得到确切触摸位置。处理器203虽能够检测到因用户触摸操作而产生的第一触摸信号获取到第一位置坐标及第二位置坐标，但无法判别出第一位置坐标与第二位置坐标中的哪一个为实际触摸位置。
由于触摸对象触摸在触摸面板201上时会有一定压力，使得触摸面板201在对应位置处发生形变，触摸面板201对应位置处的压感导体层50与触摸层30之间的距离d发生变化，致使电容发生变化而产生第二触摸信号。处理器203根据所述第二触摸信号，即根据不同电容变化值与坐标位置之间相应的关系即可判断大概触摸位置坐标(压感触摸位置)。
如图9所示例中，当在第一位置坐标M1位置触摸，处理器203可以检测到压感导体层50与第二感测电极331、第一感测电极312、第二感测电极332处相对应的压感通道512、压感通道513及压感通道514的三个通道的电容数值上的变化，同时检测到与第二位置坐标M2处第二感测电极333、第一感测电极314及第二感测电极334对应的压感通道516、压感通道517及压感通道518的三个通道的电容数值未发生变化，进而可判断出第一位置坐标M1为实际触摸位置。因为第一位置坐标M1与第二位置坐标M2相隔一定距离，通过压感导体层50在压感触摸位置的微小形变能轻易识别出用户在触摸面板201上的实际触摸位置为第一位置坐标M1。
即，处理器203根据所述第一触摸信号获取第一位置坐标M1及第二位置坐标M2，处理器203根据所述第二触摸信号获取压感触摸位置，处理器203根据所述压感触摸位置确定所述第一位置坐标与所述第二位置坐标中的一个为实际触摸位置。
可以理解，每个电极单元的第二感测电极33的数量可以为两个以上，同个电极单元的第二感测电极33与同一个第二布线37电性连接，处理器203根据第一触摸信号获取至少两个位置坐标，根据所述第二触摸信号获取压感触摸位置，处理器203根据所述压感触摸位置确定所述至少两个位置坐标中的一个为实际触摸位置。
在一实施方式中，处理器203根据所述第二触摸信号获取压感触摸位置，所述压感触摸位置为包括一定位置坐标范围的区域，例如以一直径为R的圆的区域范围，处理器203判断所述第一位置坐标及所述第二位置坐标是否位于所述压感触摸位置，若所述第一位置坐标位于所述压感触摸位置，所述第二位置坐标不位于所述压感触摸位置，则所述第一位置坐标为实际触摸位置，所述第二位置坐标为虚拟触摸位置；若所述第二位置坐标位于所述压感触摸位置，所述第一位置坐标不位于所述压感触摸位置，则所述第二位置坐标为实际触摸位置，所述第一位置坐标为虚拟触摸位置。
在一实施方式中，处理器203根据所述第二触摸信号，即根据不同电容变化值与坐标位置之间相应的关系获取压感触摸位置，处理器203计算所述第一位置坐标与所述压感触摸位置之间的第一间距，及所述第二位置坐标与所述压感触摸位置之间的第二间距，若所述第一间距不大于预设阀值，所述第二间距大于所述预设阀值，则所述第一位置坐标为实际触摸位置；若所述第二间距不大于所述预设阀值，若所述第一间距大于所述预设阀值，则所述第二位置坐标为实际触摸位置，所述第一位置坐标为虚拟触摸位置。
本实施方式中提供的触摸面板201及触摸装置200，触摸层30结合压感导体层50，在减少边框区布线的同时，确保触摸面板201的触摸输入的精确度。
请参阅图10，本公开还提供一种应用于触摸面板的触摸检测方法，所述触摸面板包括层叠设置的触摸层与压感导体层，所述触摸层的每个第一感测电极与所述压感导体层的一个压感通道的位置对应，所述触摸层的每个第二感测电极与所述压感导体层的一个压感通道的位置对应，所述触摸层的第一感测电极与同一个第一布线电性连接，其包括以下步骤：
步骤101，根据用户在触摸面板上的触摸操作，所述触摸面板的触摸层产生第一触摸信号，所述触摸面板的压感导体层产生第二触摸信号。
步骤102，根据所述第一触摸信号获取至少两个位置坐标，根据所述第二触摸信号获取压感触摸位置。
步骤103，根据所述压感触摸位置，确定所述至少两个位置坐标中的一个位置坐标为实际触摸位置。
所述根据所述至少两个位置坐标及所述压感触摸位置，获取实际触摸位置，包括：根据所述压感导体层在所述压感触摸位置的电容变化，确定所述至少两个位置坐标中的一个位置坐标为实际触摸位置。
所述根据所述至少两个位置坐标及所述压感触摸位置，获取实际触摸位置，包括：根据所述压感导体层在所述压感触摸位置的电阻变化，确定所述至少两个位置坐标中的一个位置坐标为实际触摸位置。
请参阅图11，图11为本公开第三实施方式提供的触摸层的部分平面示意图。触摸层包括多个第一感测电极72(图11中仅示例性地示出5个)、多个第二感测电极74(图11中仅示例性地示出4个)、一个第一布线以及多个第二布线(图11中仅示例性地示出2个)。
多个第一感测电极72与多个第二感测电极74为同层设置，并且多个第一感测电极72间隔排列，在相邻的两个第一感测电极之间设置有一个第二感测电极。即第一感测电极与第二感测电极对应交替排列设置。
本实施方式的触摸层与第一实施方式提供的触摸层10结构相似，不同在于，本实施方式包括多个电极单元，每个电极单元至少包括两个第二感测电极，并且同一个电极单元的第二感测电极与同一个第二布线电性连接。
如图11，每相邻两个第二感测电极组成一个电极单元，同一电极单元中的第二感测电极通过同一个第二布线连接。示例的，多个第一感测电极72包括第一感测电极721、第一感测电极722、第一感测电极723、第一感测电极724及第一感测电极725；多个第二感测电极74包括第二感测电极741、第二感测电极742、第二感测电极743及第二感测电极744。
在本实施方式中，同个电极单元的每个第二感测电极的图案均不相同，以使同个电极单元的每个第二感测电极在与触摸对象(手指、触控笔等)发生接触时，该第二感测电极与触摸对象产生的电容变化有所不同，即每个第二感测电极在与触摸对象接触发生电容变化以生成的第一触摸信号不同，进而使处理器根据接收到第一触摸信号，能够根据不同的第一触摸信号识别第一触摸信号的信号源为该电极单元的哪个第二感测电极，获取触摸位置等触摸参数以进行相应的控制操作，从而避免处理器对触摸对象触摸的位置坐标的误判。
需要说明的是，本公开实施例中所述的同个电极单元的每个第二感测电极的图案，可以包括第二感测电极的外边缘形状形成的图案，也可以是相同或者不同的第二感测电极的外边缘形状形成的图案的情况下，在第二感测电极内设置的镂空部的形状图案。上述的图案形式，目的是为了通过使同一电极单元中两个第二感测电极的图案不同，达到所述两个第二感测电极的有效表面积不同，以便在两个第二感测电极与触摸对象发生接触产生电容变化后生成的第一触摸信号不同。例如，第二感测电极的外边缘形状形成的图案可以是矩形、梯形、三角形或者其他多边形，还可以是带有弧形边缘的图形。同样的，第二感测电极内设置的镂空部的形状图案可以是矩形、梯形、三角形或者其他多边形，还可以是带有弧形边缘的图形，而且，第二感测电极内设置的镂空部也可以是多个，多个镂空部的形状图案可以相同，也可以不同。以下以能够实现功能且加工制作难度较低、良率高的形式进 行举例说明。
示例地，第一感测电极72与第二感测电极74交替排列，且第二感测电极741和第二感测电极742组成电极单元、第二感测电极743和第二感测电极744组成另一个电极单元。第二感测电极741和第二感测电极742均设置为矩形，第二感测电极741具有矩形镂空部，而第二感测电极742不具有镂空部。同样地，第二感测电极743和第二感测电极744均设置为矩形，第二感测电极743具有矩形镂空部，而第二感测电极744不具有镂空部。
示例性的，当触摸对象的触摸位置为M时，第二感测电极741、第一感测电极722及第二感测电极742会产生第一触摸信号并通过第二布线传输至处理器。处理器能够根据接收到的第一触摸信号识别出触摸位置M，从而达到该触摸面板的触摸识别功能。
当然，在实际使用中，根据上述示例还可以相应增加和设置第一感测电极以及第二感测电极的个数，并且还可以将更多的具有不同图案的第二感测电极连接至同一第二布线组成具有电极单元序列的电极单元。从而提高触摸面板的触摸识别精度。在实际使用中，每个电极单元之间可以具有相同的电极单元序列，当然，也可以具有不同的电极单元序列，对此本领域技术人员可以根据具体情况而设定。
为避免出现触摸盲点，通常同一电极单元的每个第二感测电极之间还排列有其他电极单元的第二感测电极。即不同的电极单元通过第二感测电极交替排列形成叉指型插合。其中，不同的电极单元可以由不同个数的第二感测电极组成，本实施方式中，对此不做限制。
由于同个电极单元的第二感测电极与同个第二布线电性连接，避免了每个第二感测电极分别单独与第二布线连接，从而减少了布线的数量，有效减小触摸面板的边框区的宽度，进一步的促进触摸面板的无框化及全屏化发展。
如图12所示，示例地，多个第一感测电极71包括第一感测电极711、第一感测电极712、第一感测电极713、第一感测电极714及第一感测电极715；多个第二感测电极73包括第二感测电极731、第二感测电极732、第二感测电极733及第二感测电极734。
其中，第一感测电极与第二感测电极交替排列，且第二感测电极731和第二感测电极733组成电极单元、第二感测电极732和第二感测电极734组成另一个电极单元。两个电极单元之间通过各自的第二感测电极呈叉指型插合。
第一布线75分别与第一感测电极711、第一感测电极712、第一感测电极713、第一感测电极714及第一感测电极715连接；第二布线77包括分别与第二感测电极731和第二感测电极733连接的第二布线771，以及分别与第二感测电极732和第二感测电极734连接的第二布线772。第一布线75、第二布线771以及第二布线772均分别与处理器连接。
示例一，如图12所示，第二感测电极731的外边缘图案设置为矩形，且具有矩形的镂空部；第二感测电极733的外边缘图案设置为矩形，但不具有镂空部。第二感测电极732 的外边缘图案设置为矩形，且具有矩形镂空部；第二感测电极734的外边缘图案设置为矩形，但不具有镂空部。即由第二感测电极731、第二感测电极733组成的电极单元和第二感测电极732、第二感测电极734组成另一个电极单元具有相同的电极单元序列。
该示例的触摸面板，示例性的，当触摸对象触摸至第一位置坐标M1时，处理器会获取到第二感测电极731、第一感测电极712以及第二感测电极732分别通过第二布线771、第一布线75以及第二布线772传输的第一触摸信号。从而确定触摸对象的触摸位置为M1。尽管第二位置坐标M2的第一触摸信号同样分别通过第二布线771、第一布线75以及第二布线772传输至处理器，但是M2的第一触摸信号的信号源为第二感测电极733、第一感测电极714以及第二感测电极734，由于第二感测电极731与第二感测电极733的图案不同，与触摸对象接触产生的电容变化不同，发出的第一触摸信号不同、第二感测电极732与第二感测电极734的图案不同，与触摸对象接触产生的电容变化不同，发出的第一触摸信号不同，所以处理器能够对收到的第一触摸信号进行区分识别精准确定触摸对象的触摸位置为第一位置坐标M1。因此本实施方式的触摸面板具有更高的触摸识别精度。
示例二，如图13所示，第二感测电极731的外边缘图案设置为矩形，且具有三角形镂空部；第二感测电极733的外边缘图案设置为矩形，但不具有镂空部。第二感测电极732的外边缘图案设置为矩形，且具有三角形镂空部；第二感测电极734的外边缘图案设置为矩形，但不具有镂空部。即由第二感测电极731、第二感测电极733组成的电极单元和第二感测电极732、第二感测电极734组成另一个电极单元具有相同的电极单元序列。
该示例的触摸面板，示例性的当触摸对象触摸至第一位置坐标M1时，处理器会获取到第二感测电极731、第一感测电极712以及第二感测电极732分别通过第二布线771、第一布线75以及第二布线772传输的第一触摸信号。从而确定触摸对象的触摸位置为M1。第三位置坐标N2不会被处理器误判的原理与上述示例一相同，此处不做赘述。N2位置同样分别通过第二布线771、第一布线75以及第二布线772传输至处理器，且N2位置的信号源与M1位置相同，但是由于第二感测电极731以及第二感测电极732的镂空部为三角形，同一第二感测电极上不同位置与触摸对象接触时产生的电容变化不同，发出的第一触摸信号也就不相同，所以N2位置的第一触摸信号与M1位置的不同，因此处理器能够根据收到的第一触摸信号精准确定触摸对象的触摸位置M1，而不会误判为N2位置。进一步的提高本实施方式触摸面板的触摸识别精度。
示例三，如图14，第二感测电极731的外边缘图案设置为三角形；第二感测电极733的外边缘图案设置为矩形。第二感测电极732的外边缘图案设置为三角形；第二感测电极734的外边缘图案设置为矩形。即由第二感测电极731、第二感测电极733组成的电极单元和第二感测电极732、第二感测电极734组成另一个电极单元具有相同的电极单元序列。
该示例的触摸面板，示例性的，当触摸对象触摸至M1位置时，处理器会获取到第二感测电极731、第一感测电极712以及第二感测电极732分别通过第二布线771、第一布线75以及第二布线772传输的第一触摸信号。从而确定触摸对象的触摸位置为M1。N2位置不会被处理器误判的原理与上述示例一相同，此处不做赘述。N2位置不会被处理器误判的原理与上述示例二相同，此处也不做赘述。该示例进一步的提高本实施方式触摸面板的触摸识别精度，且更容易加工设置。
在本实施方式中，本领域技术人员还可以在不付出创造性劳动的情况下，根据上述示例设置更多的第一感测电极以及第二感测电极，并将第二感测电极组成更多的具有电极单元序列的电极单元，或将更多具有不同图案的第二感测电极组成更长的电极单元序列(电极单元序列包括的第二感测电极个数即为该电极单元序列的长度)，以使该触摸面板具有更好的触摸识别精度以及拥有更少的布线个数。
例如，如图15所示，多个第一感测电极71包括第一感测电极711、第一感测电极712、第一感测电极713、第一感测电极714、第一感测电极715、第一感测电极716以及第一感测电极717；多个第二感测电极73包括第二感测电极731、第二感测电极732、第二感测电极733、第二感测电极734、第二感测电极735以及第二感测电极736。其中，第一感测电极71与第二感测电极73相互交替排列，且第二感测电极731、第二感测电极733及第二感测电极735组成电极单元，第二感测电极732、第二感测电极734及第二感测电极736组成另一个电极单元。两个电极单元之间通过各自的第二感测电极呈叉指型插合。第一感测电极均连接至同一第一布线，两个电极单元分别连接至对应的两个第二布线。
第二感测电极731、第二感测电极732、第二感测电极733、第二感测电极734、第二感测电极735以及第二感测电极736的外边缘图案均设置为矩形。其中，第二感测电极731、第二感测电极732具有三角形的镂空部；第二感测电极733、第二感测电极734具有矩形的镂空部；第二感测电极735、第二感测电极736不具有镂空部，分别组成两个具有三个第二感测电极的相同电极单元序列。当然，在实际应用中，第二感测电极还可以设置为其他图案，例如椭圆形、三角形、圆形等的外边缘形状或镂空部，图15仅作为示例，在实际应用中，第一感测电极和第二感测电极的个数应根据具体需求进行设置，并且此处对于电极单元序列中的第二感测电极的具体情况分别为何种设置不做限制，只要同一电极单元序列中各个第二感测电极的图案相互不同即可。
又例如，如图16，多个第一感测电极71包括第一感测电极711、第一感测电极712、第一感测电极713、第一感测电极714、第一感测电极715、第一感测电极716以及第一感测电极717；多个第二感测电极73包括第二感测电极731、第二感测电极732、第二感测电极733、第二感测电极734、第二感测电极735以及第二感测电极736。其中，第一感测 电极与第二感测电极相互交替排列，且第二感测电极731、第二感测电极734组成电极单元；第二感测电极732、第二感测电极735组成另一电极单元；第二感测电极733、第二感测电极736组成又一个电极单元。三个电极单元之间通过各自的第二感测电极呈叉指型插合。第一感测电极均连接至同一第一布线，三个电极单元分别连接至对应的第二布线。
第二感测电极731、第二感测电极732、第二感测电极733、第二感测电极734、第二感测电极735以及第二感测电极736的外边缘图案均设置为矩形。其中，第二感测电极731、第二感测电极732及第二感测电极733具有三角形的镂空部；第二感测电极734、第二感测电极735及第二感测电极736不具有镂空部，分别组成三个具有两个第二感测电极的电极单元序列。当然，在实际应用中，第二感测电极还可以设置为其他具体情况，例如椭圆形、三角形、圆形等的外边缘图案或镂空部，图16仅作为示例，在实际应用中，第一感测电极和第二感测电极的个数应根据具体需求进行设置，并且此处对于电极单元序列中的第二感测电极的具体情况分别为何种设置不做限制，只要同一电极单元序列中各个第二感测电极的图案相互不同即可。
以上两个举例，分别例举了增加电极单元长度以进一步减少第二布线个数、增加电极单元个数以进一步提高触摸面板触摸精度两种本实施方式中在不付出创造性劳动下，本领域技术人员即可实现的使该触摸面板具有更好的触摸识别精度以及拥有更少的布线个数的方案。当然，本领域技术人员基于本实施方式还能够再进行其他变形设置，此处不再赘述。
以上所述是本公开的优选实施例，应当指出，对于本技术领域的普通技术人员来说，在不脱离本公开原理的前提下，还可以做出若干改进和润饰，这些改进和润饰也视为本公开的保护范围。
工业实用性
