本发明涉及触摸控制技术领域，尤其涉及一种触摸屏及触摸显示装置。
背景技术
压力检测技术可以在传统电容触摸屏的触摸位置以外增加一个触摸压力值，即触摸检测结果从原来的二维坐标(x，y)到三维坐标(x，y，z)，以实现三维触摸控制体验。其中，x、y分别表示触摸位置的横坐标和纵坐标，z表示触摸压力的大小。通过在触摸屏中引入压力检测功能，可以提高触控输入的表达范围及效率。目前，存在利用电容触摸屏检测手指接触面积大小来判断触摸压力的方案，但该方案针对不同用户的手指可能存在较大的误差。同时，还存在通过新增额外的压力传感器来实现触摸压力检测的方案，但由于传感器不是透明的，无法布置在显示屏上方，只能布置在显示屏周边，导致玻璃盖板安装方式受限，且影响防水设计；或者将压力传感器通过基板设置于显示屏背后，玻璃盖板在压力作用下的变形需要压迫显示屏变形才能传递到屏幕背后的压力传感器，导致压力检测灵敏度低，且影响屏幕可靠性；此外，压力传感器的设置需要增加触摸屏的厚度，且存在装配难度大，成本高等问题。

在本实施例中，所述第一方向与所述第二方向正交，所述第一方向和所述第二方向所在的平面与所述第一表面111和第二表面113平行，所述触摸操作的压力的方向与所述第一表面111和第二表面113垂直。可以理解，在一种实施方式中，可以建立三维坐标系，如图3所示，其中，沿y轴的方向为第一方向，沿x轴的方向为第二方向，沿z轴的方向为触摸操作的压力的方向。
在本实施例中，通过在所述第一导电层130上形成相互交替排列的第一触摸感应电极131和第一压力感应电极133，并在所述第二导电层150上形成相互交替排列的第二触摸感应电极151和第二压力感应电极153，进而可以通过所述第一触摸感应电极131和所述第二触摸感应电极151来检测针对所述触摸屏100的触摸操作的位置，并通过所述第一压力感应电极133和所述第二压力感应电极153来检测针对所述触摸屏100的触摸操作的压力，无需增加所述触摸屏100的厚度即可实现触摸操作的压力检测，且由于所述第一导电层130和所述第二导电层150均为透明的，从而可以将所述触摸屏100直接贴合于显示屏的上面， 有利于降低生产成本和装配难度。
请参阅图3，在一种实施方式中，所述第一触摸感应电极131包括多个依次连接的第一触摸感应区域1311，所述第一压力感应电极133包括多个依次连接的第一压力感应区域1331，所述第一触摸感应电极131的多个第一触摸感应区域1311与相邻的第一压力感应电极133的多个第一压力感应区域1331交错排列。
所述第二触摸感应电极151包括多个依次连接的第二触摸感应区域1511，所述第二压力感应电极153包括多个依次连接的第二压力感应区域1531，所述第二触摸感应电极151的多个第二触摸感应区域1511与相邻的第二压力感应电极153的多个第二压力感应区域1531交错排列。
在本实施方式中，通过将所述第一触摸感应电极131设置为多个依次连接的第一触摸感应区域1311，从而可以在相邻的两个第一触摸感应电极131之间形成对应的多个相互贯通的镂空区，进一步通过在所述镂空区设置多个依次连接的第一压力感应区域1331以形成所述第一压力感应电极133，并通过将所述第二触摸感应电极151设置为多个依次连接的第二触摸感应区域1511，从而可以在相邻的两个第二触摸感应电极151之间形成对应的多个相互贯通的镂空区，进一步通过在所述镂空区设置多个依次连接的第二压力感应区域1531以形成所述第二压力感应电极153，从而实现在同一透明基板上形成用于检测触摸操作的位置的触摸感应电极和用于检测触摸操作的压力感应电极，在不增加所述触摸屏100的厚度的情况下实现了触摸造成的压力检测。
可以理解，在一种实施方式中，所述第一触摸感应区域1311、第一压力感应区域1331、第二触摸感应区域1511及第二压力感应区域1531均可以设置为呈菱形状的区域，任意两个相邻的第一触摸感应电极131的第一触摸感应区域1311之间在第二方向上相互对齐，任意两个相邻的第一压力感应电极133的第一压力感应区域1331之间在第二方向上相互对齐，任意两个相邻的第二触摸感应电极151的第二触摸感应区域1511之间在第一方向上相互对齐，任意两个相邻的第二压力感应电极153的第二压力感应区域1531之间在第一方向上相互对齐。
在本实施例中，所述第一触摸感应电极131和所述第一压力感应电极133为由所述第一导电层130形成的导电图案；所述第二触摸感应电极151和所述第二压力感应电极153为由所述第二导电层150形成的导电图案。其中，所述第一触摸感应电极131的导电图案和所述第二触摸感应电极151的导电图案相同，所述第一压力感应电极133和所述第二压力感应电极153的导电图案相同。所述第一触摸感应电极131的导电图案与所述第一压力感应电极133的导电图案互补，所述第二触摸感应电极151的导电图案与所述第二压力感应电极153的导电图案互补。所述第一触摸感应电极131的导电图案与所述第二触摸感应电极151的导电图案在正投影方向上互补，所述第一压力感应电极133的导电图案与所述第二压力感应电极153的导电图案在正投影方向上互补。其中，正投影方向是指投射线垂直于所述第一导电层130和所述第二导电层150的方向。所述第一触摸感应电极131的导电图案与所述第二触摸感应电极151的导电图案在正投影方向上互补是指：所述第一触摸感应电极131的第一触摸感应区域1311在所述第二导电层150上的投影位于所述第二触摸感应电极151的第二触摸感应区域1511之间的空隙内，并与所述第二触摸感应区域1511 互补；也就是说，所述第一触摸感应区域1311在所述第二导电层150上的投影位于与所述第二触摸感应区域1511相互交错的区域内。
可以理解，所述第一触摸感应电极131和所述第一压力感应电极133可以由所述第一导电层130经过蚀刻或激光雕刻工艺形成；所述第二触摸感应电极151和所述第二压力感应电极153可以由所述第二导电层150经过蚀刻或激光雕刻工艺形成。可以理解，通过同一导电层经过蚀刻或激光雕刻工艺形成触摸感应电极和压力感应电极，可以有效缩短所述触摸屏的工艺制成，降低生产成本。
在一种实施方式中，所述第一压力感应电极133和所述第二压力感应电极153为呈迂回结构的应变电阻线路。可以理解，所述迂回结构的应变电阻线路的具体迂回形式这里并不做限定，例如，可以是如图3中所示的方形迂回结构，也可以是菱形、圆形等其他形式的迂回结构。
通过将所述第一压力感应电极133和所述第二压力感应电极153设置为呈迂回结构的应变电阻线路，从而可以在相同面积的压力感应区域内设置更长的应变电阻线路，迂回结构的应变电阻线路还可以使得压力感应电极在受到压力作用时的形变更加灵敏，从而根据压力的变化灵敏地改变应用电阻的阻值，故可以增加压力检测的灵敏度。
请参阅图4，假设所述多个第一压力感应电极133对应的应变电阻为RT1、RT2、RT3、RT4…，所述多个第二压力感应电极153对应的应变电阻为RB1、RB2、RB3、RB4…。可以理解，在没有接收到针对所述触摸屏100的触摸操作，或者触摸操作不具有压力时，应变电阻RT1、RT2、RT3、RT4…、RB1、RB2、RB3、RB4…的阻值无变化。当有压力作用于所述触摸屏100时，应变电阻RT1、RT2、RT3、RT4…、RB1、RB2、RB3、RB4…的阻值将会发生变化，且越靠近触摸操作接触点的位置应变电阻的阻值变化越大。因此，可以通过分别检测RT1、RT2、RT3、RT4…、RB1、RB2、RB3、RB4…的阻值，即可确定触摸操作的位置处于阻值最大(例如RTi)的第一压力感应电极133和阻值最大(例如RBj)的第二压力感应电极153的交界处，同时，可以根据阻值最大的第一压力感应电极133对应的应变电阻的阻值RTi和阻值最大的第二压力感应电极153对应的应变电阻的阻值RB j计算出所述触摸操作的压力。
如图4中所示，假设符号“+”所示位置为触摸操作的位置，且该触摸操作携带压力，同时，若该触摸操作的位置靠近应变电阻为RT2的第一压力感应电极133和应变电阻为RB3的第二压力感应电极153的交界处，则由于应变电阻RT2对应的第一压力感应电极133和应变电阻RB3对应的第二压力感应电极153受到压力作用而产生的形变最大，对应的应变电阻RT2、RB3的阻值也最大，即通过分别检测RT1、RT2、RT3、RT4…、RB1、RB2、RB3、RB4…的阻值，可以得到应变电阻RT2、RB3的阻值最大，并可根据应变电阻RT2对应的第一压力感应电极133和应变电阻RB3对应的第二压力感应电极153的位置确定触摸操作的压力点位置。同时，还可以根据应变电阻RT2、RB3的阻值的变化大小，计算得到触摸操作对应的压力大小。
请参阅图5，在本发明一个实施例中，提供一种触摸显示装置200，包括显示屏210及触摸屏100，所述显示屏210包括显示面211，所述触摸屏100贴合于所述显示面211上，用于接收针对所述触摸显示装置的三维触摸操作，其中，所述触摸屏100的具体结构及功 能可以参照图1至图4所示实施例中描述，此处不再赘述。

在一种实施方式中，所述触摸显示装置还包括处理器250，所述处理器250可以设置于一电路板(图未示)上。所述第一触摸感应电极131、所述第二触摸感应电极151、所述第一压力感应电极133和所述第二压力感应电极153均通过透明的电极走线引导至所述触摸显示装置200的非显示区域213，进而通过所述非显示区域213内的走线与所述处理器250电性连接。可以理解，图5中仅示出了第一触摸感应电极131和第一压力感应电极133与所述处理器250的连接方式，第二触摸感应电极151及第二压力感应电极153与所述处理器250之间可以参考第一触摸感应电极131和第一压力感应电极133与所述处理器250的连接方式进行电连接。
在本实施方式中，通过透明的电极走线将所述触摸感应电极和压力感应电极引导至所述触摸显示装置200的非显示区域213，进而与所述处理器250电性连接，其中，所述透明的电极走线可以采用与所述触摸感应电极和压力感应电极相同的导电层通过蚀刻等工艺形成，从而具有与所述触摸感应电极和压力感应电极相同的通透性，可以防止电极走线对显示屏造成遮挡。
在一种实施方式中，所述处理器250用于获取所述多个第一触摸感应电极131和所述多个第二触摸感应电极151输出的感应电压，并根据所述多个第一触摸感应电极131和所述多个第二触摸感应电极151输出的感应电压的大小，确定所述针对所述触摸显示装置200的三维触摸操作的位置。
在本实施方式中，由于所述多个第一触摸感应电极131沿第一方向延伸并沿第二方向排列，所述多个第二触摸感应电极151沿第二方向延伸并沿第一方向排列，因而通过检测所述多个第一触摸感应电极131输出的感应电压即可判断针对所述触摸显示装置200的三维触摸操作在第二方向上的位置，并通过检测所述多个第二触摸感应电极151输出的感应电压即可判断针对所述触摸显示装置200的三维触摸操作在第一方向上的位置，进而根据所述第二方向上的位置和第一方向上的位置，确定所述针对所述触摸显示装置200的三维触摸操作的位置。
在一种实施方式中，所述处理器250用于获取所述多个第一压力感应电极133和所述多个第二压力感应电极153输出的感应电压，并根据所述多个第一压力感应电极133和所述多个第二压力感应电极153输出的感应电压的大小，确定所述针对所述触摸显示装置200的三维触摸操作的压力。
在本实施方式中，由于所述多个第一压力感应电极133沿第一方向延伸并沿第二方向排列，所述多个第二压力感应电极153沿第二方向延伸并沿第一方向排列，因而通过检测所述多个第一压力感应电极133输出的感应电压即可判断针对所述触摸显示装置200的三 维触摸操作在第二方向上的压力分布，并通过检测所述多个第二压力感应电极153输出的感应电压即可判断针对所述触摸显示装置200的三维触摸操作在第一方向上的压力分布，进而根据所述第二方向上的压力分布和第一方向上的压力分布，确定所述针对所述触摸显示装置200的三维触摸操作的压力。
