技术领域
本公开涉及显示技术领域，特别是涉及一种触控显示装置及其制作方法。
背景技术
目前应用最广泛的触摸屏为电容式触摸屏，其结构是在阵列基板上制作出相对设置的两个压力电极，根据平行板电容器原理，当电容式触摸屏受到压力后，两个压力电极之间的距离发生变化时，从而根据电容的参数变化确定出对屏幕的按压操作。
但是，在相关技术中的结构中，阵列基板上还设置有其他信号线，因此压力感应精度容易受到信号干扰。此外，在制作工艺上，需要先在阵列基板形成压力电极的基材图层，该基材图层一般是塑料材料制成，在一定程度上会影响屏幕的透光率，且对于一些大尺寸屏幕，塑料基材上的压力电极容易发生变形，压力感应实现较为困难。
有鉴于此，当前亟需一种能够克服上述问题的压力识别方案。
发明内容
本公开的目的是解决相关技术中的触控显示装置压力电极易受到信号干扰，以及透光率不高的问题。
为实现上述目的，一方面，本公开提供一种触控显示装置，包括对盒的触控面板和显示面板，其中，所述触控面板与所述显示面板之间设置有形变图层，所述形变图层在所述触控面板受到压力时发生形变；
所述触控面板朝向所述显示面板的一侧设置有多个第一电极；
所述显示面板朝向所述触控面板的一侧形成有多个第二电极，所述第二电极与所述第一电极一一对应，每一第二电极与对应的第一电极形成压力感应电 容；
其中，所述触控显示装置还包括有压力检测模块，所述压力检测模块用于检测所述压力感应电容的电容变化值，并根据所述电容变化值确定所述触控面板受到的压力值。
可选地，所述第一电极在所述显示面板上的正投影与对应的所述第二电极在所述显示面板上的正投影重合。
可选地，所述形变图层由绝缘的粘合胶形成，所述触控面板和所述显示面板通过所述粘合胶对盒固定。

所述第二电极形成在所述彩膜基板远离所述阵列基板的一侧。
可选地，所述彩膜基板上具有覆盖所述第二电极的彩色滤光片。
可选地，所述触控面板包括：
衬底基板；
形成在所述衬底基板上的触控电极；
覆盖所述触控电极的绝缘层；以及
在所述绝缘层上的的所述第一电极。
可选地，所述第二电极与所述彩膜基板远离所述阵列基板的一侧表面直接接触。
可选地，所述多个第一电极以阵列形式均匀分布在所述触控面板朝向所述显示面板的一侧表面，所述多个第二电极以阵列形式均匀分布在所述显示面板朝向所述触控面板的一侧表面。
另一方面，本公开还提供一种触控显示装置的制作方法，包括形成触控面板和显示面板的步骤，其中，形成的所述触控面板的一侧上形成有第一电极，形成的显示面板的一侧上形成有第二电极；
所述制作方法还包括：
通过绝缘的粘合胶将所述触控面板和所述显示面板进行对盒固定；其中，所述触控面板形成有所述第一电极的一侧朝向所述显示面板形成有所述第二电极的一侧。
可选地，通过绝缘的粘合胶将所述触控面板和所述显示面板进行对盒固定， 包括：
在所述触控面板形成有所述第一电极的一侧或所述显示面板形成有所述第二电极的一侧涂布绝缘的所述粘合胶；

可选地，通过绝缘的粘合胶将所述触控面板和所述显示面板进行对盒固定，还包括：
在涂布完所述粘合胶后，对所述粘合胶进行真空脱泡和/或半固化处理。
本公开的上述方案具有如下有益效果：
在本公开的触控显示装置中，压力电极形成在触控面板与显示面板的盒间，从而避开了触控面板以及显示面板上的信号干扰。进一步地，由于压力电极占据的是盒内空间，因此不会增加触控显示装置的整体厚度，符合当前显示装置超薄化的发展趋势。此外，显示面板侧的压力电极可直接就形成在显示面板的最外侧的玻璃基板上，区别于相关技术中需要额外形成塑料的基材图层，因此本实施例的方案不仅具有更高的透光率，且制作工艺也得到了简化，同时玻璃基板在强度上要高于塑料基材，特别适用于大屏幕的触控显示装置。

具体实施方式
为使本公开要解决的技术问题、技术方案和优点更加清楚，下面将结合附 图及具体实施例进行详细描述。
针对相关技术中所存在的触控显示装置压力电极易受到信号干扰，以及触控显示装置透光率不高的问题，本公开提供一种解决方案。
一方面，如图1所示，本公开的一些实施例提供一种触控显示装置，包括对盒的触控面板1和显示面板2，以及压力检测模块6。在本公开的一些实施例中，压力检测模块6可以如图4所示的方式设置。
触控面板1朝向显示面板2的一侧设置有多个第一电极3，显示面板2朝向触控面板1的一侧形成有多个第二电极4。
第二电极4与第一电极3一一对应，每一第二电极4与对应的第一电极3形成压力感应电容。在实际应用中，相互对应的第一电极3和第二电极4为正对设置。即第一电极3在显示面板2上的正投影与对应的第二电极4在显示面板2上的正投影重合。作为示例性介绍，第一电极3和第二电极4可以如图2所示那样(即图2中阴影方格)，以阵列的方式均匀分布在触控区域上。
触控面板1与显示面板2之间还设置有形变图层5，该形变图层5能够在触控面板1受到压力时发生形变，使得第一电极3与第二电极4之间的距离d发生变化，进而造成压力感应电容的电容值发生变化。本公开的一些实施例的压力检测模块可以检测到该压力感应电容的电容变化值，并根据电容变化值确定触控面板1受到的压力值。
通过上述结构设计可以知道，在本公开的一些实施例的触控显示装置中，压力电极形成在触控面板与显示面板的盒间，从而避开了触控面板以及显示面板上的信号干扰。进一步地，由于压力电极占据的是盒内空间，因此不会增加触控显示装置的整体厚度，符合当前显示装置超薄化的发展趋势。此外，显示面板侧的压力电极可直接就形成在显示面板的最外侧的玻璃基板上，区别于相关技术中需要额外形成塑料的基材图层，因此本公开的实施例的方案不仅具有更高的透光率，且制作工艺也得到了简化，同时玻璃基板在强度上要高于塑料基材，特别适用于大屏幕的触控显示装置。
作为示例性介绍，在实际应用中，本公开的一些实施例的形变图层可以由绝缘的粘合胶形成(例如：固态透明光学胶OCA、紫外线硬化树脂OCR等)，触控面板和显示面板通过该粘合胶对盒固定。由于粘合胶具有一定的弹性，不仅能够符合触控显示装置在受到压力后发生形变的要求，还能对触控显示装提供 缓冲保护作用，防止结构发生损坏。
在具体结构中，如图3所示，本公开的一些实施例的触控面板1包括：衬底基板11；形成在衬底基板11上的触控电极12；覆盖触控电极的绝缘层13。其中，第一电极3可以形成在该绝缘层13上。
对应地，进一步参考图3，本公开的一些实施例的显示面板2包括彩膜基板21和阵列基板22。其中，第二电极4形成在彩膜基板21背向所述阵列基板22的一侧。作为可行的方案，彩膜基板21的彩色滤光片23在第二电极4形成后再制作，即彩色滤光片23在彩膜基板21上覆盖第二电极4。
可见，本公开的一些实施例通过在显示面板2的彩膜基板21外侧，以及触控面板1的绝缘层13表面光刻形成相同对应压力电极图案，从而构成电容传感器阵列。利用按压导致触控显示装置的形变，电容传感器的电容值随之发生变化，识别电容值的变化可以实现压力感应。本公开的实施例不仅与相关技术中的OGS触控技术兼容，同时由于电容传感器阵列位于触控面板的下方，可有效屏蔽触控信号，从而实现精确的压力感应。
此外，本公开的一些实施例还提供一种针对上述触控显示装置的制作方法，包括形成触控面板和显示面板的步骤。其中，形成的触控面板的一侧上形成有第一电极；形成的显示面板的一侧上形成有第二电极。本公开的一些实施例的制作方法还包括：
通过绝缘的粘合胶将触控面板和显示面板进行对盒固定；其中，触控面板形成有第一电极的一侧朝向显示面板形成有第二电极的一侧。
具体地，通过绝缘的粘合胶将所述触控面板和显示面板进行对盒固定，包括：
在触控面板形成有第一电极的一侧或显示面板形成有第二电极的一侧涂布绝缘的粘合胶；
通过粘合胶将触控面板形成有第一电极的一侧与显示面板形成有第二电极的一侧进行粘合，完成对盒。
具体地，本公开的实施例在涂布完粘合胶后，对该粘合胶进行真空脱泡和/或半固化处理。其中，真空脱泡处理是为了保证粘合胶的贴合更加牢固，半固化处理是在对盒前，提高粘合胶的硬度，避免对盒的过程中使粘合胶坍塌变形。
显然，本公开的实施例的制作方法与本公开的触控显示装置相对应，因此能够实现相同的技术效果。
以上所述是本公开的优选实施方式，应当指出，对于本技术领域的普通技术人员来说，在不脱离本公开所述原理的前提下，还可以作出若干改进和润饰，这些改进和润饰也应视为本公开的保护范围。
