具体实施方式
为使本公开实施例的目的、技术方案和优点更加清楚，下面将结合本公开实施例的附图，对本公开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公开的一部分实施例，而不是全部的实施例。基于所描述的本公开的实施例，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，都属于本公开保护的范围。
除非另外定义，本公开使用的技术术语或者科学术语应当为本公开所属领域内具有一般技能的人士所理解的通常意义。本公开中使用的“第一”、“第二”以及类似的词语并不表示任何顺序、数量或者重要性，而只是用来区分不同的组成部分。“包括”或者“包含”等类似的词语意指出现该词前面的元件或者物件涵盖出现在该词后面列举的元件或者物件及其等同，而不排除其他元件或者物件。“连接”或者“相连”等类似的词语并非限定于物理的或者机械的连接，而是可以包括电性的连接，不管是直接的还是间接的。
在研究中，本申请的发明人发现，随着显示面板PPI(Pixels Per Inch)的增高，显示面板中子像素单元的尺寸逐渐减小。此时，通常的触控电极图案会与子像素单元阵列相互干涉而产生摩尔纹，从而影响产品的良率。因此，触控电极的设计除了要考虑其电学性能外，也不可避免地需要对其光学性能进行设计。
本发明实施例提供一种触控电极结构以及触控显示面板。该触控电极结构包括衬底基板以及设置在衬底基板上的多个第一触控电极和多个第二触控电极。多个第一触控电极沿第一方向延伸，各第一触控电极呈多边形且包括多个第一边，各第一边的延伸方向与第一方向之间的夹角范围为20-25度；多个第二触控电极沿第二方向延伸，各第二触控电极呈多边形且包括多个第二边，各第二边的延伸方向与第二方向之间的夹角范围为20-25度。由此，该触控电极结构可避免采用该触控电极结构的触控显示面板出现摩尔纹。
下面结合附图对本发明实施例提供的触控电极结构以及触控显示面板进行说明。
实施例一
本实施例提供一种触控电极结构，如图1所示，该触控电极包括衬底基板101以及设置在衬底基板101上的多个第一触控电极110和多个第二触控电极 120。多个第一触控电极110沿第一方向延伸，各第一触控电极110呈多边形且包括多个第一边111，各第一边111的延伸方向与第一方向之间的夹角范围为20-25度；多个第二触控电极120沿第二方向延伸，各第二触控电极120呈多边形且包括多个第二边121，各第二边121的延伸方向与第二方向之间的夹角范围为20-25度。如图1所示，第一触控电极110与第一方向的夹角a的范围为20-25度，第二触控电极120与第二方向的夹角b的范围为20-25度。需要说明的是，上述的各第一边可与第一方向具有相同的夹角也可具有不同的夹角，只要其夹角范围在20-25度即可；上述的各第二边可与第二方向具有相同的夹角也可具有不同的夹角，只要其夹角范围在20-25度即可。
在本实施例提供的触控电极结构中，由于第一触控电极和第二触控电极都具有菱形形状、第一边的延伸方向与第一方向之间的夹角范围为20-25度且第二边的延伸方向与第二方向之间的夹角范围为20-25度，该触控电极结构具有与用于显示的子像素单元阵列不相似的图案，并且各第一触控电极和各第二触控电极的边缘可与子像素单元阵列和行方向或列方向呈20-25度的夹角，可避免与子像素阵列产生干涉，从而可避免摩尔纹的产生。另一方面，由于各第一触控电极和各第二触控电极的边缘可与子像素单元阵列和行方向或列方向呈20-25度的夹角，此时透过各第一触控电极和各第二触控电极的边缘(第一边或第二边)的光可来自不同的颜色的子像素单元(显示不同颜色的子像素单元)，沿各第一触控电极和各第二触控电极的边缘(第一边或第二边)，具有相同颜色的子像素单元连续出现的周期可缩短至人眼分辨率的极限(在20-25度具有较好的效果)，从而可有效消除摩尔纹。需要说明的是，上述的多个第一触控电极除了沿第一方向延伸之外，还可包括多行沿第一方向延伸的多个第一触控电极以覆盖整个触控面板。同样地，上述的多个第二触控电极除了沿第一方向延伸之外，还可包括多列沿第一方向延伸的多个第一触控电极以覆盖整个触控面板。
例如，在本实施例一示例提供的触控电极结构中，如图1所示，多边形为菱形，即各第一触控电极110呈菱形且包括四个第一边111；各第二触控电极120呈菱形且包括四个第二边121。当然，多边形还可为其他多边形，例如，六边形、八边形等，本发明实施例在此不作限制。另外，各第一边的长度可以相同也可不同，各第二边的长度可以相同也可不同，本发明实施例在此不作限制。
例如，在本实施例一示例提供的触控电极结构中，如图1所示，第一方向垂直于第二方向。当本实施例提供的触控电极结构应用于触控显示面板时，第一方向可为触控显示面板中子像素单元阵列的行方向，第二方向可为触控显示面板中像素单元阵列的列方向，或者，第一方向可为触控显示面板中像素单元阵列的列方向，第二方向可为触控显示面板中像素单元阵列的行方向。
例如，在本实施例一示例提供的触控电极结构中，如图1所示，相邻的第一触控电极110电性相连，相邻的第二触控电极120通过条状的桥接部130电性相邻。由此，第一触控电极110和第二触控电极120可同层设置，从而可见效本实施例提供的触控电极结构的厚度，更利于采用本实施例提供的触控电极结构的触控显示面板(例如，手机)的轻薄化。例如，在桥接部130下还设置有绝缘层(未示出)，以使桥接部130与第一触控电极110绝缘。
例如，在本实施例一示例提供的触控电极结构中，第一触控电极可为触控驱动电极，第二触控电极可为触控感应电极，或者，第一触控电极可为触控感应电极，第二触控电极可为触控驱动电极。
实施例二
在实施例一的基础上，本实施例提供一种触控电极结构。图2示出本实施例提供的触控电极结构一个图案单元的示意图，如图2所示，第一触控电极110与第一方向的夹角a的范围为20-25度，第二触控电极120与第二方向的夹角b的范围为20-25度。该触控电极结构还包括多个第一浮置电极140和多个第二浮置电极150。多个第一浮置电极140与多个第一触控电极110一一对应设置，各第一浮置电极140包括两个第一子浮置电极145，两个第一子浮置电极145分别设置在与其对应的第一触控电极110两侧并且与第一触控电极110间隔第一距离S1。多个第二浮置电极150与多个第二触控电极120一一对应设置，各第一浮置电极150包括两个第二子浮置电极155，两个第二子浮置电极155分别设置在与其对应的第二触控电极120两侧并且与第二触控电极120间隔第二距离S2。由此，多个第一浮置电极140和多个第二浮置电极150可减少第一触控电极110和第二触控电极120之间的电容从而提高触控的精度，并且可使得整个触控电极结构的光透过率更加均匀，提高采用本实施例提供的触控电极结构的触控显示面板的显示效果。例如，第一浮置电极和第二浮置电极可采用与第一触控电极和第二触控电极相同的材料制作，并具有相同的厚度以进一步增加整个触控电极结构的光透过率的均匀度。
例如，在本实施例提供的触控电极结构中，如图2所示，多个第一浮置电极140和多个第二浮置电极150设置在阵列基板101上没有设置第一触控电极110和第二触控电极120的区域，且相邻的第一浮置电极140和第二浮置电极150间隔第三距离S3设置。由此，可通过设置S1、S2、S3的大小将第一触控电极、第二触控电极、第一浮置电极以及第二浮置电极占衬底基板的面积比例尽可能地提高，从而一方面可进一步提高整个触控电极结构的光透过率的均匀度，另一方面可使得第一触控电极、第二触控电极、第一浮置电极以及第二浮置电极之间的间隔(S1、S2、S3)小于采用本实施例提供的触控电极结构的触控显示面板中子像素单元的宽度，从而避免摩尔纹现象的发生。
例如，当子像素单元的宽度为30μm时，第一距离S1、第二距离S2以及S3第三距离小于30μm。
例如，在本实施例一示例提供的触控电极结构中，第一距离S1、第二距离S2以及第三距离S3相等。
例如，在本实施例一示例提供的触控电极结构中，如图2所示，设置在第一触控电极110两侧的各第一子浮置电极145包括与第一触控电极110的第一边111相对的第三边1450以及沿第三方向延伸的第一斜边1451和沿第四方向延伸的第二斜边1452，设置在第二触控电极120两侧的各第二子浮置电极155包括与第二触控电极120的第二边121相对的第四边1550以及沿第三方向延伸的第三斜边1551和沿第四方向延伸的第四斜边1552，第三方向垂直于第四方向。由此，设置在第一触控电极两侧的两个第一子浮置电极与其对应第一触控电极(包括第一触控电极和第一子浮置电极之间的间隔)可构成一个大致的矩形图案，设置在第二触控电极两侧的两个第二子浮置电极与其对应第二触控电极(包括第二触控电极和第二子浮置电极之间的间隔)可构成一个大致的矩形图案，从而便于覆盖整个阵列基板。
例如，在本实施例一示例提供的触控电极结构中，如图2所示，第一斜边1451、第二斜边1452、第三斜边1551以及第四斜边1552包括多个首尾相连的弯折部170，弯折部170包括第一弯折部171和第二弯折部172，第一弯折部171的延伸方向与第一方向的夹角c的范围为20-25度，第二弯折部172的延伸方向与第二方向的夹角d的范围为20-25度。由此，该第一斜边、第二斜边、第三斜边以及第四斜边中的第一弯折部和第二弯折部可与子像素单元阵列和行方向或列方向呈20-25度的夹角，可避免与子像素阵列产生干涉，从而 可避免摩尔纹的产生。另一方面，由于第一弯折部和第二弯折部可与子像素单元阵列和行方向或列方向呈20-25度的夹角，此时透过第一斜边、第二斜边、第三斜边以及第四斜边的光可来自不同的颜色的子像素单元(显示不同颜色的子像素单元)，沿第一斜边、第二斜边、第三斜边以及第四斜边，具有相同颜色的子像素单元连续出现的周期可缩短至人眼分辨率的极限，从而可有效消除摩尔纹。
实施例三
本实施例提供一中触控显示面板，如图3所示，该触控显示面板包括显示面板200以及设置在显示面板200上的触控电极结构100，也就是说，触控电极结构100设置在显示面板200用于显示的一侧。触控电极结构100可为上述实施例一中任一项的触控电极结构。由此，该触控显示面板可消除摩尔纹现象。另外，该触控显示面板具有与其包括的触控电极结构对应的其他技术效果，在此不再赘述。
例如，在本实施例一示例提供的触控显示面板中，触控电极结构100包括：多个第一浮置电极和多个第二浮置电极。多个第一浮置电极与多个第一触控电极一一对应设置，各第一浮置电极包括两个第一子浮置电极，两个第一子浮置电极分别设置在与其对应的第一触控电极两侧并且与第一触控电极间隔第一距离S1。多个第二浮置电极与多个第二触控电极一一对应设置，各第一浮置电极包括两个第二子浮置电极，两个第二子浮置电极分别设置在与其对应的第二触控电极两侧并且与第二触控电极间隔第二距离S2(具体参见实施例二中的相关描述)。显示面板200包括用于显示的多个子像素单元，并且各子像素单元具有第一宽度，第一距离S1小于第一宽度，第二距离S2小于第二宽度。由此，第一触控电极和第一浮置电极之间的间隔小于子像素单元的宽度，第二触控电极和第二浮置电极之间的间隔小于子像素单元的宽度，从而可有效地防止摩尔纹现象的发生。
例如，在本实施例一示例提供的触控显示面板中，多个第一浮置电极和多个第二浮置电极设置在阵列基板上没有设置第一触控电极和第二触控电极的区域，且相邻的第一浮置电极和第二浮置电极间隔第三距离设置(具体参见实施例二中的相关描述)。第三距离小于第一宽度，由此，第一浮置电极和第二浮置电极之间的间隔小于子像素单元的宽度，从而可有效地防止摩尔纹现象的发生。
例如，在本实施例一示例提供的触控显示面板中，如图4a-4f所示，多个子像素单元210呈矩阵排列，第一方向为矩阵的行方向，第二方向为矩阵的列方向。
例如，在本实施例一示例提供的触控显示面板中，如图4a-4f所示，多个子像素单元210具有不同颜色，且同一列的子像素单元具有同样的颜色。图4a-4f示出了第一触控电极和第一浮置电极、第二触控电极和第二浮置电极或第一浮置电极和第二浮置电极之间的间隔D的延伸方向与子像素单元阵列的列方向的夹角从0到25度时，透过上述间隔D的子像素单元的光的颜色分布情况。如图4a所示，当间隔D的延伸方向与子像素单元阵列的列方向的夹角为0度时，透过间隔D的子像素单元的光均为红色(也可均为黄色或蓝色，此处以红色为例)，此时容易发生摩尔纹现象，随着间隔D的延伸方向与子像素单元阵列的列方向的夹角逐渐增加，如图4b-4f，透过间隔D的子像素单元的光颜色种类逐渐增加，并且具有相同颜色的子像素单元连续出现的周期可缩短至人眼分辨率的极限(在20-25度具有较好的效果)，从而可有效消除摩尔纹。
有以下几点需要说明：
(1)本发明实施例附图中，只涉及到与本发明实施例涉及到的结构，其他结构可参考通常设计。
(2)为了清晰起见，在用于描述本发明的实施例的附图中，层或微结构的厚度和尺寸被放大。可以理解，当诸如层、膜、区域或基板之类的元件被称作位于另一元件“上”或“下”时，该元件可以“直接”位于另一元件“上”或“下”，或者可以存在中间元件。
(3)在不冲突的情况下，本发明同一实施例及不同实施例中的特征可以相互组合。
以上所述，仅为本公开的具体实施方式，但本公开的保护范围并不局限于此，任何熟悉本技术领域的技术人员在本公开揭露的技术范围内，可轻易想到变化或替换，都应涵盖在本公开的保护范围之内。因此，本公开的保护范围应以所述权利要求的保护范围为准。
