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。
目前的触控显示装置一般由触控检测部分和触控控制器组成，触控检测部分安装在显示屏的前面用于检测触控位置，然后将检测的信息发送给控制器，并将其转换成坐标，输送给中央处理器，同时接收中央处理器返回的信号并加以执行，实现人机互动。然而由于触控显示装置是将触控电极制作在显示屏的上方，当光从显示屏射出经过触控显示装置时，其上的电极图案就会对光产生影响。由于光是通过由规则排列的黑色矩阵(BM)组成的RGB的基本单元产生的，当光从其穿过，遇到规则的金属网格传感器时，会产生两种频率接近的等幅 正弦波，合成信号的幅度将按照两个频率之差变化，在空间上会产生拍频，导致摩尔纹的出现。针对上述问题，发明人进行了深入研究，提出通过金属网格的结构设计来改善摩尔纹的问题，进而改善触控显示装置的光学性能，获得使用性能较佳的触控显示装置。
有鉴于此，在本公开的一个方面，本公开提供了一种金属网格。根据本公开的实施例，参照图1，所述金属网格包括：至少两根第一金属线10，所述至少两根第一金属线10彼此平行、间隔设置；至少两根第二金属线20，所述至少两根第二金属线20彼此平行、间隔设置，且所述至少两根第二金属线20与所述至少两根第一金属线10相交。为了有效改善摩尔纹现象，获得显示效果较佳的触控显示装置，发明人对第一金属线的宽度A1和第二金属线的宽度A2、相交的夹角B、相邻两根第一金属线之间的距离C1以及相邻两根第二金属线之间的距离C2等参数进行了设定，获得了有效改善采用金属网格的触控显示装置摩尔纹的最佳设计方案。具体的，所述第一金属线10的宽度A1和第二金属线20的宽度A2分别为1-6微米，所述第一金属线10和所述第二金属线20之间的夹角B为66-70度，相邻两根第一金属线10之间的距离C1和相邻两根第二金属线20之间的距离各C2分别为160-170微米或200-210微米。由此，设计简单、方便、易于实现。形成金属网格的材料价格便宜，无需使用昂贵的ITO材料，成本低，并且上述尺寸金属网格的结构设计可以有效改善光学差异问题，采用该金属网格的触控显示装置改善摩尔纹效果较佳，光学性能良好且使用性能较佳。
根据本公开的实施例，形成第一金属线10和第二金属线20的金属没有特别限制，本领域技术人员可以根据需要灵活选择。例如包括但不限于银、铜等金属，由此，可以代替价格昂贵的ITO材料，成本低。
根据本公开的实施例，所述第一金属线10的宽度A1和第二金属线20的宽度A2分别为1-2微米。线宽较宽时，则摩尔纹现象十分严重，显示效果较差，线宽较细时，则制作难度较高，良率较低，不利于工业化生产，而设置第一金属线10的宽度A1和第二金属线20的宽度A2在上述范围，既易于实现，又能够很好的改善摩尔纹现象，同时透光性能良好，从而能够大大提高触控显示装置的显示效果。
根据本公开的实施例，第一金属线10的宽度A1与第二金属线20 的宽度A2之间的差异没有特别限制，本领域技术人员可以根据需要灵活选择。根据本公开的一些实施例，所述第一金属线10的宽度A1和所述第二金属线20的宽度A2相等。此种设计易于加工制备，制备步骤简单易于操作，且可以有效改善触控显示装置中产生的摩尔纹问题，摩尔纹现象较弱，有效改善触控显示装置的光学性能，使其使用性能得到提高。
根据本公开的实施例，为了进一步提高改善摩尔纹的效果，且简化制备步骤，参照图2，所述至少两根第一金属线10和所述至少两根第二金属线20相交并形成至少一个菱形。此种设计使得可以改善采用该金属网格的触控显示装置中产生摩尔纹问题，均匀性好，显示画面不会因不同位置摩尔纹效果不同而产生明显差异，摩尔现象较弱，有效改善触控显示装置的光学性能，使其使用性能得到提高。
根据本公开的实施例，参照图2，所述菱形的相邻两边形成的锐角B为66-70度，且为整数，所述菱形的高C为160-170微米或200-210微米，且为整数，其中，构成菱形的金属线的宽度相等且为A，A为1-6微米，且为整数。在上述范围内，采用该金属网格的触控显示装置的摩尔纹等级不高于2级，光学性能和显示效果理想。在本公开上下文中，菱形的高C是指菱形的两条对边之间的距离。
根据本公开的一些具体实施例，所述至少两根第一金属线10和所述至少两根第二金属线20相交并形成至少一个菱形，构成所述菱形的金属线的宽度A＝4±1微米，其中，一个具体示例中，所述菱形的锐角B为66度，所述菱形的高C为170微米；另一个具体示例中，所述菱形的锐角B为66度，所述菱形的高C为210微米；再一个具体示例中，所述菱形的锐角B为67度，所述菱形的高C为160微米；又一个具体示例中，所述菱形的锐角B为67度，所述菱形的高C为170微米；另一个具体示例中，所述菱形的锐角B为67度，所述菱形的高C为210微米；另一个具体示例中，所述菱形的锐角B为68度，所述菱形的高C为160微米；另一个具体示例中，所述菱形的锐角B为68度，所述菱形的高C为170微米；另一个具体示例中，所述菱形的锐角B为69度，所述菱形的高C为160微米；另一个具体示例中，所述菱形的锐角B为69度，所述菱形的高C为170微米；另一个具体示例中，所述菱形的锐角B为70度，所述菱形的高C为160微米；另一个具体示例 中，所述菱形的锐角B为70度，所述菱形的高C为170微米；另一个具体示例中，所述菱形的锐角B为70度，所述菱形的高C为200微米。满足上述设计条件的金属网格能够有效降低采用该金属网格的触控显示装置中摩尔纹出现的可能，摩尔纹等级不超过2级，使得该触控显示装置的光学性能和使用性能优良。
在本公开的另一方面，本公开提出了一种触控显示装置。根据本公开的实施例，所述触控显示装置包括触控模组，所述触控模组中的触控电极由前面所述的金属网格形成。由此，结构简单易于实现，无需使用昂贵的ITO材料，成本低，且采用前面所述的金属网格，可以有效改善触控显示装置的摩尔纹问题，提高触控显示装置的光学性能。
根据本公开的实施例，触控模组的具体结构没有特别限制，本领域技术人员可以根据需要灵活选择，例如，可以包括触控电极、设置在触控电极之间的绝缘层等结构。在本公开的一些实施例中，触控电极的具体结构、形状也没有特别限制，例如参照图3a、图3b和图3c，触控电极可以包括层叠设置的驱动电极210和感应电极220，绝缘层230设置在驱动电极210和感应电极220之间，驱动电极210由第一金属网格形成，感应电极220由第二金属网格形成，且第一金属网格和第二金属网格可以分别构造为多个条形电极211和221。例如，图3a示例性示出驱动电极210中由第一金属网格形成的三个条形电极211，并且图3b示例性示出感应电极220中由第二金属网格形成的三个条形电极221。其中，驱动电极210和感应电极220的具体设置方式没有特别限制，例如多个条形电极可以相互交叉，如相互垂直(图3c所示情况)等。
根据本公开的实施例，为了进一步提高改善摩尔纹的效果，参照图7，第一金属网格包括至少一个第一菱形212，第二金属网格包括至少一个第二菱形222。在示例性实施例中，第一菱形212和第二菱形222形状和尺寸相同，并且第一菱形212的顶点在第二金属网格上的正投影与第二菱形222的对称中心重叠。由此，可以进一步改善触控显示装置中产生摩尔纹问题，均匀性好，显示画面不会因不同位置摩尔纹效果不同而产生明显差异，摩尔现象较弱，有效改善触控显示装置的光学性能，使其使用性能得到提高。根据本公开的实施例，所述触控显示装置进一步包括显示模组，所述显示模组包括阵列基板、彩膜 基板和偏光片，所述显示模组与所述触控模组层叠设置。根据本公开的实施例，显示模组的像素密度与触控模组中金属网格触控电极最终形成的摩尔纹密切相关，并且相互匹配。显示模组的像素密度为250-300个/英寸时，例如包括但不限于260个/英寸、270个/英寸、280个/英寸、288个/英寸、290个/英寸等，显示模组的像素密度在上述范围内可大大降低摩尔纹的严重程度，可以有效改善摩尔纹现象，提高触控显示装置的显示质量和光学性能，而像素密度过高或过低，则在相同条件下摩尔纹越严重。
根据本公开的实施例，上述显示模组的具体种类和结构没有特别限制，只要满足使用要求，本领域技术人员可以根据需要灵活选择，例如显示模组可以为液晶显示模组，也可以为OLED显示模组；显示模组的结构也可以为常规液晶显示模组或OLED显示模组的结构，在此不再一一赘述。
根据本公开的实施例，触控模组和显示模组的具体设置位置不受特别限制，只要能够满足使用要求，本领域技术人员可以根据需要灵活选择，可以按照任何已知的触控显示装置的设置方式进行设置，例如包括但不限于on cell触控显示装置、in cell触控显示装置、OGS触控显示装置等，即在本公开的一些实施例，所述触控模组可以设置于所述显示模组的彩膜基板和偏光片之间，也可以设置在所述显示模组的阵列基板和彩膜基板之间或者设置在所述触控显示装置的保护盖板上。由此，结构简单易于实现，适用范围较广，可以很好地满足市场需要，并且含有上述触控模组的显示装置光学性能良好，摩尔纹现象较弱，画面均匀性好。
