具体实施方式
下面详细描述本公开的实施例。下面描述的实施例是示例性的，仅用于解释本公开，而不能理解为对本公开的限制。实施例中未注明具体技术或条件的，按照本领域内的文献所描述的技术或条件或者按照产品说明书进行。所用试剂或仪器未注明生产厂商者，均为可以通过市购获得的常规产品。
本公开是基于发明人的以下认识和发现而完成的：触控显示装置通常利用触控电极层来感受用户触屏操作，并向触控芯片(Touch IC)输出电信号。当用户用湿手指接近触控显示装置的触控表面或者水溅射到触控表面上，手指虽未与触控表面接触，但由于水相对介电常数远大于空气相对介电常数，水层下部(即浸湿区域)电场远强于未浸湿区域。触控电极层极易将浸湿区域错误地识别为手触部位而向Touch IC发出电信号，导致用户意料之外的触屏反馈。针对上述技术问题，发明人发现，当触控显示装置正常工作时，背光源所发出的光的入射角大于临界角θ1时在保护盖板(一般为玻璃盖板)与空气界面处发生全反射。在浸湿区域，当背光源所发出的光的入射角大于临界角θ2时也会发生全反射。由于水折射率在玻璃与空气之间，可知θ2必然大于θ1。因此，在浸湿区域边缘，反射光较弱。在浸湿区域内部的反射光与浸湿区域外部的反射光具有基本相同的光强。如果是用户手指触控，则在手指触控区域的边缘具有较弱的反射光强，在手指触控区域的内部具有基本一致的反射光强。因此，可以在触控显示装置中设置能够感受反射光的异常变化的光传感膜层，从而识别水层的浸湿区域，进而有效避免水层误触的发生。
有鉴于此，在本公开的一个方面，本公开实施例提供了一种触控组件。参照图1，该触控组件包括：触控电极层100，配置为感测触控表面TS内的触控区域TA；以及与所述触控电极层100层叠设置的光 传感膜层200；其中，所述光传感膜层200的光接收表面201朝向所述触控表面TS。可选地，如图1所示，所述光传感膜层200位于所述触控电极层100的一侧，用于感测来自所述触控表面TS的反射光。本领域技术人员能够理解，“光传感膜层的光接收表面”指的是光传感膜层用于接收和感测光线的表面，入射至该表面的光线因此能够被检测。
该触控组件结构简单，易于实现。光传感膜层通过感测触控表面的反射光线的强度，可以识别水层浸湿区域，进而可以有效避免水层误触。由此，可以有效避免浸湿区域导致的意料之外的触屏反馈，降低水层干扰效果较佳。利用以上构造识别水层浸湿误触的灵敏度较高，提高了用户体验效果。
在本公开的上下文中，“触控表面”是指与触控物(如用户手指、触控笔等)直接接触的表面，而该触控表面可以是触控组件的部件的表面，也可以是含有触控组件的装置或设备的部件的表面，例如可以为触控组件的基板的外表面，也可以是含有该触控组件的触控屏或触控显示装置的外表面。在本公开的实施例中，所述触控表面TS与所述触控电极层100可以是基本平行的。本领域技术人员能够理解，对于柔性显示装置来说，所述触控表面TS与所述触控电极层100可以具有基本不变的间距。
在本公开的上下文中，“层叠设置”指的是以堆叠的方式将两个或两个以上的层/板状元件放置在一起。层叠设置的两个或两个以上的层/板状元件可以直接接触，也可以不直接接触。在本公开的上下文中，误触不仅包括由水层导致的误触(mistaken touch caused by water layer)，也包括由其他液体导致的误触。在本公开的实施例中，为叙述方便，仅以水层导致的误触作为实例进行说明。
另外，可以理解的是，触控电极层的具体结构没有特别限制，只要能够有效发挥检测触控区域的作用，本领域技术人员可以根据实际需要灵活选择。例如，触控电极层可以包括本领域任何已知的常规电容式触控电极。在本公开的一些实施例中，触控电极层包括发射电极(Tx)和接收电极(Rx)，并且Tx和Rx的设置方式没有特别限制。本领域技术人员可以根据实际需要灵活选择Tx和Rx的设置方式。例如，Tx和Rx可以同层设置也可以异层设置等。
根据本公开的实施例，形成触控电极层的材料可以为氧化铟锡等 透明材料，也可以为金属(例如铜、金、银等)等不透明的材料，本领域技术人员可以根据实际需要灵活选择。
根据本公开的实施例，光传感膜层可以位于触控电极层面对触控表面的一侧，也可以位于触控电极层远离触控表面的一侧，两种设置方式均可以有效避免水层误触。其中，需要说明的是，本文中所采用的描述方式“光传感膜层位于触控电极层的一侧”可以是光传感膜层和触控电极层直接接触，也可以是光传感膜层和触控电极层未直接接触，其他类似描述同此。在本公开的一些可选实施例中，所述光传感膜层位于所述触控电极层面对所述触控表面的一侧。由此，结构简单，易于实现，光传感膜层感应触控表面的反射光的灵敏度更高，信噪比更小，避免水层误触的效果更佳，用户体验更佳。
根据本公开的实施例，如图2A所示，所述光传感膜层200包括：多个第一光传感器件210，所述多个第一光传感器件210在第一方向上间隔分布，且每个所述第一光传感器件210在第二方向上延伸；多个第二光传感器件220，所述多个第二光传感器件220在所述第二方向上间隔分布，且每个所述第二光传感器件220在所述第一方向上延伸，其中，第一方向和第二方向相互交叉。
可选地，所述多个第一光传感器件210可以布置在所述多个第二光传感器件220的顶部。类似地，所述多个第一光传感器件210也可以布置在所述多个第二光传感器件220的底部。
可选地，在一些实施例中，如图2B所示，所述光传感膜层200包括：阵列布置的多个光传感器件230。
需要说明的是，图2A和图2B仅用于说明本公开，而不能理解为对本公开的限制。具体的光传感膜层的结构可以根据实际情况进行选择，在此不再过多赘述。由此，根据第一光传感器件和第二光传感器件的交叉，可以快速、有效的定位反射光强度发生变化的边界，进而识别水层浸湿区域。
根据本公开的实施例，第一光传感器件210、第二光传感器件220和光传感器件230的形状没有特别限制，本领域技术人员可以根据实际需要灵活选择。例如第一光传感器件和第二光传感器件的形状可以各自独立的为条形、波浪形或者弓字形等。在本公开的上下文中，“光传感器件”可以是诸如光敏电阻器件、光伏器件、光电二极管等可以 将光信号转换为电压/电流信号的器件。
根据本公开的实施例，光传感膜层和触控电极层的具体设置方式没有特别限制，光传感膜层在触控表面上的正投影和触控电极层在触控表面上的正投影可以至少部分重叠，也可以不重叠。当将上述触控组件应用于触控显示装置时，为了保证显示功能正常工作，根据实际需要，光传感膜层和触控电极层可以为透明的。在本公开的一些实施例中，为了提高显示装置的透过率，多个第一光传感器件可以与Tx层叠设置，多个第二光传感器件可以与Rx层叠设置。光传感膜层与触控电极层可以接触设置，也可以间隔设置，本领域技术人员可以根据实际需要灵活选择。
在本公开的一些可选实施例中，如图1所示，所述触控电极层100在所述触控表面TS上的正投影覆盖所述光传感膜层200在所述触控表面TS上的正投影。由此，当该触控组件用于触控显示装置时，光传感膜层不会降低触控显示装置的透过率，保证显示效果良好。
根据本公开的实施例，形成光传感膜层的材料可以为在背光源出射光波段有吸收峰的半导体材料，例如可以包括但不限于光敏电阻材料或者光伏材料(例如包括但不限于非晶硅材料等)等。由此，通过检测电阻或电流，即可有效获得来自触控表面的反射光的强度，且材料来源广泛，且感应反射光的灵敏度较佳，使用性能较佳。

根据本公开的一个具体实施例，光传感膜层包括上述的第一光传感器件和第二光传感器件，其具体的工作原理可以为如下：触控表面的反射光照射到第一光传感器件和第二光传感器件上，以使得第一光传感器件和第二光传感器件产生电信号(电流或电阻)。上述电信号的强弱与反射光的强度相关，通过检测电信号大小即可获得反射光的强度。由于第一光传感器件和第二光传感器件交叉设置，根据产生电流或电阻的第一光传感器件和第二光传感器件的交叉位置则可确定不同位置的反射光强度。根据上述不同位置的反射光强度的变化，则可确定触控区域是否为水层浸湿误触。具体的，测得的光强变化趋势可以包括以下两种情况。一、在从所述触控区域的边缘向所述触控区域 的中心的方向上，反射光的强度在触控区域的边缘变弱，且从所述触控区域的边缘向所述触控区域的中心逐渐增强，该情况对应于水层浸湿误触；进一步的，控制器还可以进行一系列处理以消除水层浸湿误触的影响。二、若在从所述触控区域的边缘向所述触控区域的中心的方向上，反射光的强度在触控区域的边缘变弱，且从所述触控区域的边缘向所述触控区域的中心保持不变，该情况对应于使用者的期望的触控，此时触控区域对应于正常触摸位置(即有效触控区域)，进而进行正常的触摸反馈。

根据本公开的实施例，触控显示装置除了包括前面所述的结构之外，还可以包括封装结构、电极、CPU、外壳等等结构，在此不再过多赘述。
根据本公开的实施例，触控显示装置避免水层误触的原理可以为如下。
具体的，参照图19，在触控表面的未浸湿区域，背光源的入射角大于等于临界角θ1时会在触控表面发生全反射，形成反射光白信号(包括但不限于Tx、Rx的电流或者电阻等)；在水层900下部的浸湿区域(第N～M条Tx/Rx处)，当背光源发出的光的入射角大于等于临界角θ2时也会发生全反射，由于水的折射率在玻璃与空气之间，因此θ2必然大于θ1。因此在浸湿区域的边缘附近(第N个及第M个Tx/Rx)，由于界面属性的改变使得反射光信号发生突变(浸湿区域的信号变化可以参照图20)。具体的表现为反射光的强度明显减弱，使得第N或者第M个Tx/Rx的电信号变弱。而在浸湿区域内部，由于光通过水层后部分发生全反射，反射光强度部分恢复到正常反射光强度(即未浸湿区域的反射光强度)，进而电信号(例如电阻、电流等)强度也部分恢复。例如，图中第N+L个Tx/Rx处的电信号可以恢复到与反射光白信号相当的强度。由于全反射角、各界面材料折射率已知，当Touch IC检测到浸湿区域的异常电信号后，其可以根据Tx/Rx水平方向排列周期(相邻两个发射电极或者相邻两个接收电极之间的间距)d及电信号恢复处Tx序数差((N+L)-N＝L)得出水层厚度D。计算出水层厚度之后进而对Tx/Rx驱动信号或信号检测值进行相应补偿，扣除水层的电学影响，达到防止误触的作用。

在本公开的另一方面，本公开提供了一种制备触控组件的方法。根据本公开的实施例，参照图23，该方法包括：
