如图2所示，是所述红外触控显示装置100的俯视图，所述红外触控面板4设于所述盖板3的上表面的周边，所述红外触控面板4包括多个发射传感器41和多个接收传感器42。所述盖板3呈矩形，包括相邻设置的第一侧边31和第二侧边32，与所述第一侧边31相对设置的第三侧边33和与所述第二侧边32相对设置的第四侧边34，在所述第一侧边31和所述第二侧边32上均设有多个所述发射传感器41，在所述第三侧边33和所述第四侧边34上设有多个所述接收传感器42，所述发射传感器41和所述接收传感器42一一对应排列。
如图3所示，是本实施例的触控原理示意图，所述盖板3的上表面周边的所述发射传感器41和所述接收传感器42呈多层设置，每层设有多个所述发射传感器41和与所述发射传感器41相对应的所述接收传感器42，通过所述发射传感器41发射红外线信号和所述接收传感器42接收红外线信号进行判断实现对所述触控面板4触摸位置的定位。由于所述红外触控面板4设于所述盖板3的上表面的周边，用户可以直接在所述盖板3进行触摸和点击等操作，所述红外触控面板4用于感应触摸和点击位置，当所述红外触控面板4被触控时，所述红外线信号被遮挡使得所述接收传感器42不能接收到所述发射传感器41发射的红外线信号，从而能够检测到相应的触控位置，多组成对设置的所述发射传感器41和所述接收传感器42形成网状结构，多层所述发射传感器41和所述接收传感器42用以检测距所述盖板3有一定距离的触控，其为现有技术，在此不做赘述。
如图1所示，为了加强显示效果，所述盖板3和所述显示面板1之间设置所述微结构层5。所述微结构层5具有凹凸的漫反射面，能够实现防眩光作用。所述微结构层5的雾度大于10%。
本实施例中，所述微结构层5设于所述盖板3朝向所述光学胶层2一侧的表面。
如图4所示，所述微结构层5包括一防眩膜51，即凹凸的漫反射面。所述防眩膜51（Anti-Glare Film，AG Film）是一种透明的薄膜，用在显示器或荧幕上以降低刺眼的眩光。眩光是由荧幕表面的反射光造成，会让人产生头痛，眼睛疲劳及降低工作效率。所述防眩膜51是通过将HC材料（Hard Coat，经过硬化处理过的透明膜）经过雾化处理形成，使反光倒影状况模糊化即光线散射，从而达到防眩效果。雾化处理包括使用腐蚀膜层表面具有凹凸的漫反射面的方式形成所述防眩膜51，所述防眩膜51的凹凸的漫反射面可以有效改善反射视效干扰。所述防眩膜51的材质包括光学级塑胶，优选聚甲基丙烯酸甲酯（polymethyl methacrylate，PMMA）、聚乙二醇对苯二甲酸酯（PET）、或聚苯乙烯（PS）。所述防眩膜的雾度大于10%。
本实施例中，所述防眩膜51为在所述盖板3朝向所述光学胶层2一侧的表面进行雾化处理形成。雾化处理包括使用腐蚀膜层表面的方式形成所述防眩膜51，所述微结构层5可以有效改善反射视效干扰。
如图4所示，所述微结构层5还包括一基层52；所述防眩膜51设于所述基层52上。所述基层52的存在可使得所述微结构层5能够通过所述基层52贴附至所述盖板3上，而不仅仅是在所述盖板3上通过雾化处理的方式形成所述微结构层5。这样即方便又可节约工序时间。
所述基层52的材质与所述防眩膜51的材质相同，包括光学级塑胶，优选聚甲基丙烯酸甲酯（polymethyl methacrylate，PMMA）、聚乙二醇对苯二甲酸酯（PET）、或聚苯乙烯（PS）。所述防眩膜51通过雾化处理的方式形成于所述基层52上，其中雾化处理包括使用腐蚀膜层表面具有凹凸的漫反射面的方式，即形成所述防眩膜51和所述基层52为一体结构。
实施例2
如图5所示，在第二实施例中包括第一实施例中全部的技术特征，其区别在于，第二实施例中的所述微结构层5设于所述显示面板1朝向所述光学胶层2一侧的表面，而不是第一实施例中的所述微结构层5设于所述盖板3朝向所述光学胶层2一侧的表面。
本实施例中，所述防眩膜51为在所述显示面板1朝向所述光学胶层2一侧的表面进行雾化处理形成。雾化处理包括使用腐蚀膜层表面的方式形成所述防眩膜51，所述微结构层5可以有效改善反射视效干扰。
如图4、图5所示，所述微结构层5包括所述防眩膜51和所述基层52；所述防眩膜51设于所述基层52上。所述基层52的存在可使得所述微结构层5能够通过所述基层52贴附至所述显示面板1上，而不仅仅是在所述显示面板1上通过雾化处理的方式形成所述微结构层5，这样即方便又可节约工序时间。
实施例3
如图6a、图6b所示，为了进一步地加强显示效果，在第三实施例中包括第一实施例和第二实施例中全部的技术特征，其区别在于，第三实施例中进一步设有第二层微结构层5，其设于所述盖板3和所述红外触控面板4之间。
如图6a、图6b所示，为第三实施例中的两个结构示意图，图6a与图1的区别在于，在图1的基础上在所述盖板3朝向所述光学胶层2一侧的表面增加了一个所述第二层微结构层5；图6b与图5的区别在于，在图5的基础上在所述显示面板1朝向所述光学胶层2一侧的表面增加了一个所述第二层微结构层5。通过在所述盖板3的上方设置所述第二层微结构层5、在所述盖板3的下方设置所述微结构层5，会增大所述红外触控显示装置100的雾度值，从而进一步的实现防眩光作用。
值得说明的是，在其他实施例中，可仅在所述盖板3的上方设置所述第二层微结构层5，而不在所述盖板3的下方设置所述微结构层5，其可同样实现防眩光作用。
实施例4
如图7所示，在第四实施例中包括第三实施例中全部的技术特征，其区别在于，第四实施例中所述红外触控显示装置100还包括一防眩层6，所述防眩层6设于所述显示面板1上，亦即位于所述显示面板1和所述第一层微结构层5之间。所述防眩层6的材质包括光学级塑胶，优选聚甲基丙烯酸甲酯（polymethyl methacrylate，PMMA）、聚乙二醇对苯二甲酸酯（PET）、或聚苯乙烯（PS）。所述防眩层6具有一定的雾度，其雾度大于17%，所述防眩膜的雾度大于10%，其叠加效果会进一步增大所述红外触控显示装置100的雾度值，从而进一步的实现防眩光作用。
如图7所示，本实施例优选所述防眩层6和所述微结构层5相邻设置，这样能够通过雾化处理的方式在所述防眩层6上通过雾化处理的方式形成所述微结构层5。这样即方便又可节约工序时间。
本发明的技术效果在于，提供一种红外触控显示装置，通过在盖板与红外触控面板之间设置微结构层，所述微结构层具有凹凸的漫反射面，能够实现防眩光作用，从而改善了彩虹纹现象，提高了红外触控显示装置的视觉效果。
以上所述仅是本发明的优选实施方式，应当指出，对于本技术领域的普通技术人员，在不脱离本发明原理的前提下，还可以做出若干改进和润饰，这些改进和润饰也应视为本发明的保护范围。
