Description

触摸屏、触摸屏的制备方法以及触控设备 技术领域
本发明的实施例一种触摸屏、触摸屏的制备方法以及触控设备。
背景技术
目前，触摸屏按照组成结构可以分为：外挂式触摸屏(Add on Mode Touch Panel)、覆盖表面式触摸屏(On Cell Touch Panel)、以及内嵌式触摸屏(In Cell Touch Panel)。其中，外挂式触摸屏是将触控模组与显示模组分开生产，然后贴合到一起成为具有触摸和显示功能的触摸屏，One Glass Solution(简称OGS)指在保护玻璃上直接形成透明导电膜及传感器的技术，一块玻璃同时起到保护玻璃和触摸传感器的双重作用。由于OGS技术将导电玻璃与保护玻璃集成于一片玻璃上，能够较好地满足智能终端超薄化需求，并提升显示效果。
由于显示模组中的黑色矩阵层为网格状图形，而各种结构的触摸屏中的金属网格层与显示模组中的黑色矩阵层之间会发生干涉，从而导致显示画面中可以看到背景线(即，莫尔条纹)，从而影响显示效果。
发明内容

具体实施方式
为使本发明实施例的目的、技术方案和优点更加清楚，下面将结合本发明实施例的附图，对本发明实施例的技术方案进行清楚、完整地描述。显然，所描述的实施例是本发明的一部分实施例，而不是全部的实施例。基于所描述的本发明的实施例，本领域普通技术人员在无需创造性劳动的前提下所获得的所有其他实施例，都属于本发明保护的范围。
图1示出了触摸屏的局部平面图，触摸屏包括触摸区域和位于触摸区域周边的边缘区域，这里主要示出了设置有触摸区域的一个单元的平面图，为了简便，边缘区域的黑色边框图案层及其上的布线等并未示出，但在图2的截面图中示出了，如图2所示，OGS结构的触摸屏包括：基板01，包括触摸区域和位于触摸区域周边的边缘区域；在周边区域位于基板01上的黑色边框图案层02；位于形成有黑色边框图案层02的基板01上的金属网格层03，这里，金属网格层03还包括在黑色边框图案层02上形成的布线；位于金属网格层03背离基板01一侧的绝缘层04，例如，有机绝缘层，这里，在黑色边框图案层02上的布线上也形成有绝缘层，以及位于有机绝缘层04背离基板01一侧的透明电极层05，该透明电极层05用于连接金属网格层03中的一个方向，例如，Y方向上的电极，例如连接031和032，而沿着另一个方向布置的金属网格层03中的电极则由同层设置的导电图案连接。
本发明实施例提供的触摸屏的制备方法，包括：
步骤S101：在基板上形成金属网格层；
步骤S102：形成至少一层具有抗莫尔图案的功能层，所述功能层为透明 电极层和/或绝缘层。
这里，为了干扰干涉，具有所述抗莫尔图案的功能层与所述金属网格层在观看方向上交叠。
采用本发明实施例提供的制备方法制备的触摸屏，通过形成至少一层具有抗莫尔图案的透明电极层和/或有机绝缘层，可以减少金属网格层与显示模组中的黑色矩阵层之间干涉现象的发生，进而减少显示画面中莫尔条纹的出现，提高触控设备的显示效果，另外，由于本发明实施例提供的制备方法，与现有技术相比不需要形成新的膜层，故制备工艺简单。
形成至少一层具有抗莫尔图案的功能层，示例性地可以对于已经形成的透明电极层和/或绝缘层，例如，有机绝缘层，通过曝光、显影、刻蚀等技术形成抗莫尔图案，也可以在形成透明电极层和/或有机绝缘层的同时一并形成抗莫尔图案，也就是直接形成具有抗莫尔图案的透明电极层和/或有机绝缘层。
示例性地，外挂式触摸屏(Add on Mode Touch Panel)、覆盖表面式触摸屏(On Cell Touch Panel)、以及内嵌式触摸屏(In Cell Touch Panel)中，均具有多个透明电极层和有机绝缘层，上述形成至少一层具有抗莫尔图案的功能层包括：在触摸屏的多层透明电极层和多层有机绝缘层中，只有一层透明电极层具有抗莫尔图案；或多层透明电极层均具有抗莫尔图案；或者只有一层有机绝缘层具有抗莫尔图案；或多层有机绝缘层均具有抗莫尔图案；或者在一层有机绝缘层和一层透明电极层、一层有机绝缘层和多层透明电极层、多层有机绝缘层和一层透明电极层或者多层有机绝缘层和多层透明电极层均具有抗莫尔图案。
需要说明的是，当在两层或多层上均形成抗莫尔图案时，每层形成的抗莫尔图案可以相同，也可以不同，只要可以对金属网格层与显示模组中的黑色矩阵层之间干涉形成干扰即可。
示例性地，上述步骤102中：形成至少一层具有抗莫尔图案的具有抗莫尔图案的功能层包括：
形成至少一层具有抗莫尔图案的绝缘层，例如，有机绝缘层，且至少一层具有抗莫尔图案的绝缘层，例如，有机绝缘层位于金属网格层背离基板的一侧。

以OGS结构的触摸屏为例，给出根据本发明实施例触摸屏的示例性制备方法；该制备方法包括：
步骤S201：在基板上形成黑色边框图案层；
步骤S202：在形成有黑色边框图案层的基板上形成金属网格层。
步骤S203：在金属网格层背离黑色边框图案层的一面形成第一层具有抗莫尔图案的绝缘层，例如，有机绝缘层。
进一步的，上述制备方法还包括：
步骤204：在第一层具有抗莫尔图案的绝缘层，例如，有机绝缘层上形成透明电极层；
步骤205：在透明电极层上形成第二层具有抗莫尔图案的绝缘层，例如，有机绝缘层。
上述抗莫尔图案的形状可以有多种，只要可以对金属网格层与显示模组中的黑色矩阵层之间干涉形成干扰即可。如图3和图4所示，其中：图3为本发明实施例提供的触摸屏内设置的一种抗莫尔图案示意图；图4为本发明实施例提供的触摸屏内设置的另一种抗莫尔图案示意图，可选的，抗莫尔图案包括多个条纹形成的透射光栅，或者抗莫尔图案包括多个不连续的散射点。当抗莫尔图案包括多个条纹形成的透射光栅时，光栅可以为直线也可以为曲线。
本发明的实施例还提供了一种触摸屏，包括：基板、位于基板上的金属网格，还包括：至少一层具有抗莫尔图案的功能层，该功能层为透明电极层和/或绝缘层。
本发明实施例提供的触摸屏，通过其自身内部具有的至少一层具有抗莫尔图案的功能层，例如透明电极层和/或绝缘层，来减少金属网格层与显示模组的黑色矩阵层之间干涉现象的发生，进而减少显示画面中莫尔条纹的出现，提高触控设备的显示效果。
本发明实施例提供的触摸屏，可以采用上述触摸屏的制备方法制备，也可以采用其它制备方法制备。
示例性地，至少一层具有抗莫尔图案的透明电极层和/或有机绝缘层，可 以对已经形成的透明电极层和/或有机绝缘层通过曝光、显影、刻蚀等技术形成抗莫尔图案，也可以在形成透明电极层和/或有机绝缘层的同时一并形成抗莫尔图案，也就是，直接形成具有抗莫尔图案的透明电极层和/或有机绝缘层。

示例性地，当触摸屏包括：至少一层具有抗莫尔图案的绝缘层时，所述至少一层具有抗莫尔图案的绝缘层位于金属网格层背离基板的一侧。
示例性地，当触摸屏包括：至少一层具有抗莫尔图案的绝缘层时，所述至少一层具有抗莫尔图案的绝缘层位于所述触摸屏的触控模组中。
以OGS结构的触摸屏为例，基板包括触摸区域和围绕触摸区域的周边区域，所述金属网格层包括在所述周边区域的布线以及在所述触摸区域的触控电极，触摸屏还可以包括：在周边区域位于基板和金属网格层之间的黑色边框图案层；位于金属网格层背离黑色边框图案层的一面的第一层具有抗莫尔图案的绝缘层；位于第一层具有抗莫尔图案的绝缘层上的透明电极层。
进一步的，触摸屏还可以包括：位于透明电极层上的第二层具有抗莫尔图案的绝缘层。
上述抗莫尔图案的形状可以有多种，只要可以对金属网格层与显示模组中的黑色矩阵层之间干涉形成干扰即可。如图3和图4所示，其中：图3为本发明实施例提供的触摸屏内设置的一种抗莫尔图案示意图；图4为本发明实施例提供的触摸屏内设置的另一种抗莫尔图案示意图，可选的，抗莫尔图案包括多个条纹形成的透射光栅，或者抗莫尔图案包括多个不连续的散射点。 当抗莫尔图案包括多个条纹形成的透射光栅时，光栅可以为直线也可以为曲线。
上述触摸屏可以为液晶显示屏LCD、有机发光屏OLED、等离子显示屏PDP、电子纸E-paper等。
基于上述触摸屏的优点，本发明的实施例还提供了一种触控设备，包括上述任一项所述的触摸屏以及与所述触摸屏叠置的显示模组。其中触摸屏中的至少一层具有抗莫尔图案的功能层与显示模组的黑矩阵和触摸屏的金属网格层在观看方向上叠置，例如，该功能层的位置关系可以位于黑矩阵和金属网格层之间，或者位于金属网格层外侧而不在黑矩阵和金属网格层之间。由于上述触摸屏可以减少显示画面中莫尔条纹现象的发生，提高触控设备的显示效果，所以，本发明实施例提供的触控设备具有较好的显示效果。
上述触控设备可以为数控冰箱、洗衣机等。
显然，本领域的技术人员可以对本发明实施例进行各种改动和变型而不脱离本发明实施例的精神和范围。这样，倘若本发明实施例的这些修改和变型属于本发明权利要求及其等同技术的范围之内，则本发明也意图包含这些改动和变型在内。
本申请要求于2014年12月25日递交的中国专利申请第201410826523.1号的优先权，在此全文引用上述中国专利申请公开的内容以作为本申请的一部分。
