Description

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。
以液晶型触控屏为例，通过在液晶显示面板的对置基板的表面沉积一层透明导电薄膜并经一次构图工艺处理形成的触控电极层可以包括如图1a或图1b所示的第一触控电极1010以及第二触控电极1020。
然而，在研究中，本申请的发明人注意到，由于触控电极之间需要绝缘，因此在上述构图工艺的刻蚀过程中，需在触控电极之间刻蚀出沟槽30。由于受到透明导电薄膜的材料、厚度及产线工艺能力等因素的影响，这些沟槽30的宽度多在6μm以上。基于此，如图2所示，当显示基板在不点亮或者低灰阶点亮时，在反射光照射下，不同位置处的沟槽30规律性地反射光，这在宏观上可产生明显的明暗相间的条纹，从而导致严重的消影问题，而该消影问题很难通过刻蚀工艺的调整来彻底解决。
本发明的至少一个实施例提供了一种触控电极层10，如图3-7所示，该触控电极层10包括第一触控电极101和第二触控电极102；第一触控电极101的至少部分被第二触控电极102包裹，且被第二触控电极102包裹的第一触控电极部分1011的形状为圆形或椭圆形；圆形或椭圆形的第一触控电极部分1011与包裹其的第二触控电极102之间具有第一间隙103；第一触控电极101和第二触控电极102同层设置。
例如，第一触控电极101和第二触控电极102的形成材料都可以为透明导电材料，这样可以避免触控电极层应用于显示装置时影响显示装置的透过率。当然，第一触控电极101和第二触控电极102的形成材料也可以是不透明的，在这种情况下，可以将第一、二触控电极设置于显示装置的非显示区，以避免对透过率造成影响。
需要说明的是，第一，如图4-6所示，第一触控电极101的至少部分被第二触控电极102包裹，可以是第一触控电极101的一部分被第二触控电极102包裹。
在第一触控电极101的部分被第二触控电极102包裹的基础上，圆形或椭圆形的第一触控电极部分1011与包裹其的第二触控电极102之间的第一间隙103为不闭合的图形。即，由于第一触控电极101除包括被第二触控电极102包裹的圆形或椭圆形部分外，还包括不被第二触控电极102包裹的其他部分，而对于一个完整的第一触控电极101来说，被第二触控电极102包裹的圆形或椭圆形部分和不被第二触控电极102包裹的其他部分应该是连接在 一起作为一个整体的，因此，在保证第一触控电极101和第二触控电极102绝缘的情况下，第二触控电极102则需要包括能使不被第二触控电极102包裹的其他部分和被第二触控电极102包裹的圆形或椭圆形部分相连的开口，因而也就使得上述第一间隙103不能形成为闭合的图形。
进一步的，由于被第二触控电极102包裹的第一触控电极部分1011为圆形或椭圆形，因而，第一间隙103与该第一触控电极部分1011接触的内侧的形状与该第一触控电极部分1011一致。由于上述第二触控电极102开口102a(参见图4-7)的存在，使得第一间隙103的内侧的形状只在除开口102a处外与该第一触控电极部分1011一致。基于此，考虑到上述的第一间隙103的内侧的形状越接近闭合的图形，即越接近圆形或椭圆形，光照射时反射回来的光就越不具有规律性，因此，本领域技术人员应该明白，即使上述的第一间隙103的内侧不是闭合的图形，但也应该是很接近闭合的图形。
当然，如图3所示，第一触控电极101的至少部分被第二触控电极102包裹，也可以是第一触控电极101的全部被第二触控电极102包裹。
在此基础上，上述的第一间隙103的形状是闭合的图形。
第二，第一触控电极101和第二触控电极102同层设置，即为：第一触控电极101和第二触控电极102通过一次构图工艺(即对同一薄膜进行的构图工艺)形成。
第三，在第一触控电极101的一部分被第二触控电极102包裹的情况下，每个第一触控电极101至少包括一个被第二触控电极102包裹的圆形或椭圆形部分(即至少一个第一触控电极部分1011)。基于此，每个第一触控电极101和与之对应的第二触控电极102之间也相应的具有至少一个第一间隙103。
本发明实施例提供了一种触控电极层10，由于被第二触控电极102包裹的第一触控电极部分1011的形状为圆形或椭圆形，因此被第二触控电极102包裹的第一触控电极101与第二触控电极102之间的第一间隙103的内侧也是闭合或近似闭合的圆形或椭圆形，因而当光照射到第一间隙103的内侧时可使反射回来的光不具有规律性，从而在一定程度上可改善图1a和图1b中由于触控电极之间的沟槽规律性反光而导致的消影问题。此外，采用上述的包裹方式设计第一触控电极101和第二触控电极102，相对图1a和图1b所 示的方式可大大增加第一触控电极101和第二触控电极102的相对面积，从而可有效提高触控信号量，增加触控性能。
例如，第一间隙103各处等间距。即：第一间隙103的外侧(即第一间隙103的靠近第二触控电极102的一侧)也为闭合或近似闭合的圆形，第一间隙103为圆环形或近似于圆环形；或者，第一间隙103的外侧为闭合或近似闭合的椭圆形，第一间隙103为椭圆环形或近似于椭圆环形。
示例的，如图3所示，第一触控电极101全部被第二触控电极102包裹，且第一触控电极101的形状为圆形；圆形的第一触控电极101与包裹其的第二触控电极102之间具有圆环形的第一间隙103。
在此基础上，如图8所示，无论光从哪个方向照射，不管光是照射到第一间隙103的内侧还是外侧，其反射回来的光均是无规律方向性的，类似于漫反射，因此，图3所示的实施例可以更好的改善上述的消影问题。
示例的，如图4所示，第一触控电极101的部分被第二触控电极102包裹，且被第二触控电极102包裹的第一触控电极部分1011的形状为圆形，被第二触控电极102包裹的圆形第一触控电极部分1011和不被第二触控电极102包裹的其他部分通过设置在第二触控电极102上的开口连接成为整体；圆形的第一触控电极部分1011与包裹其的第二触控电极102之间具有近似圆环形的第一间隙103。
在此基础上，与图8类似，无论光从哪个方向照射，不管光是照射到第一间隙103的内侧还是外侧，其反射回来的光均是无规律方向性的，类似于漫反射，因此，图4所示的实施例可以更好的改善上述的消影问题。
或者，如图5和6所示，第一触控电极101的部分被第二触控电极102包裹，且被第二触控电极102包裹的第一触控电极部分1011的形状为椭圆形，被第二触控电极102包裹的椭圆形第一触控电极部分1011和不被第二触控电极102包裹的其他部分通过设置在第二触控电极102上的开口连接成为整体；椭圆形的第一触控电极部分1011与包裹其的第二触控电极102之间具有近似椭环形的第一间隙103。
在此基础上，与图8类似，无论光从哪个方向照射，不管光是照射到第一间隙103的内侧还是外侧，其反射回来的光均是无规律方向性的，类似于漫反射，因此，图5和图6所示的实施例可以更好的改善上述的消影问题。
需要说明的是，对于图5和图6中椭圆形的第一触控电极部分1011，可通过调节其长短轴的比例来调整相应椭圆形的具体形状，具体在此不做限定，只要当光照射到第一间隙103后其反射回来的光不具有规律性即可。
基于上述，考虑到如图4-6所示的实施例中每个第一触控电极101可以不只包括一个被第二触控电极102包裹的部分，因此，如图4-6所示，优选第一触控电极101的一部分被第二触控电极102包裹，即，第二触控电极102包括开口102a，第一触控电极101包括第一部分101a、第二部分101b和第三部分101c；第一部分101a被第二触控电极102包裹，第一部分101a和第三部分101c通过位于第二触控电极102开口102a处的第二部分101b相连；且在开口102a处，第二触控电极102和第一触控电极101的第三部分101c之间的第二间隙104呈弧形。
这样，可以进一步避免触控电极之间的间隙产生规律性反光的现象。
进一步，例如，如图4所示，沿第一方向，第二触控电极102两两相邻设置，第一触控电极101设置在相邻的第二触控电极102沿第一方向的两侧；沿第二方向，相邻两个第一触控电极101之间具有第三间隙105，且第三间隙105位于对应的第二触控电极102的中间部分；相邻两个第二触控电极102之间具有第四间隙106；第一方向和第二方向为不同的方向。
这里，优选，每个第一触控电极101包括4个圆形或椭圆形的第一部分101a，每个第二触控电极102包括4个包裹部分，以保证更好的触控性能。
在此基础上，参考图4所示，在第二方向上，第一触控电极101和第二触控电极102按如下方式排布：在第二方向上，每个第一触控电极101的其中两个圆形或椭圆形的第一部分101a被其中一个第二触控电极102的两个包裹部分包裹，另外两个圆形或椭圆形的第一部分101a被另外一个第二触控电极102的两个包裹部分包裹；每个第二触控电极102的其中两个包裹部分包裹其中一个第一触控电极101的两个圆形或椭圆形的第一部分101a，另外两个包裹部分包裹另外一个第一触控电极101的两个圆形或椭圆形的第一部分101a。即，沿第二方向，第三间隙105和第四间隙106是相互错开的。
本发明实施例中，将第一触控电极101与第二触控电极102设计成常用的1T2R(一个触控驱动电极对应2个触控感应电极)方式，可适用于各厂家不同的触控IC(Integrated Circuit，集成电路)。相比目前一家IC对应一 种触控电极层的图形，每验证一种IC都需要开发一个光罩，开发成本高且未来量产IC选择性也受影响等问题，本发明实施例可以避免开发新的IC导致的成本增加，因此，本发明实施例中的触控电极层10的图形可作为标准化进行大面积推广。
进一步，例如，如图4所示，在第二方向上，第一触控电极101还包括设置在第四间隙106之间的部分。这样，可以进一步增加第一触控电极101和第二触控电极102的相对面积，以提高触控信号量。
基于上述任一实施例，如图7所示，例如，触控电极层10还包括与第一触控电极101连接且同层的第一触控电极走线201以及与第二触控电极102连接且同层的第二触控电极走线202。这样，通过一次构图工艺既形成第一触控电极101和第二触控电极102，又形成第一触控电极走线201和第二触控电极走线202，因此，可以避免构图工艺次数的增加。
例如，本发明实施例提供的触控电极层可以应用于触控电极层中的第一触控电极和第二触控电极之间的沟槽的宽度在6μm以上的情形，也就是说，上述第一间隙103的宽度可以大于或等于6微米。
本发明的至少一个实施例还提供了一种触控电极层，如图9所示，该触控电极层10包括同层设置的第一触控电极101和第二触控电极102；第一触控电极101包括被第二触控电极102包裹的第一触控电极部分1011，第一触控电极部分1011的边缘1011a为曲线形边缘，第一触控电极部分1011与包裹其的第二触控电极102之间具有间隙103’。
例如，第二触控电极102的包裹第一触控电极部分1011的边缘102b为曲线形边缘。
需要说明的是，本发明实施例中的曲线形边缘可以为圆形边缘、椭圆形边缘或其他曲线形边缘，只要该曲线形边缘上的任意点的曲率大于0即可。此外，本发明实施例中第一触控电极、第二触控电极、第一触控电极部分和间隙的设置可参考上述任一实施例提供的触控电极层中的相关描述，这里不再赘述。
本发明的至少一个实施例还提供了一种触摸屏，该触摸屏包括显示面板以及上述任一实施例提供的触控电极层10。
例如，该触控电极层10可以位于显示面板的外侧，即触摸屏为外置式触 摸屏；当然，触控电极10也可集成在显示面板中，即内嵌式触摸屏。具体可根据实际情况进行设定。
需要说明的是，本发明实施例中不对显示面板的类型进行限定，其可以是液晶显示面板，有机电致发光二极管显示面板等，具体在此不做限定。
例如，当显示面板为液晶显示面板时，显示面板中的阵列基板可以包括薄膜晶体管，与薄膜晶体管的漏极电连接的像素电极。在此基础上，该阵列基板还可以包括公共电极。对于共平面切换型(In-Plane Switch，简称IPS)阵列基板而言，像素电极和公共电极同层间隔设置，且均为条状电极；对于高级超维场转换型(Advanced-super Dimensional Switching，简称ADS)阵列基板而言，像素电极和公共电极不同层设置，其中在上的电极为条状电极，在下的电极为板状电极。基于此，显示面板还包括对置基板，例如彩膜基板。
当显示面板为有机电致发光二极管(Organic Light-Emitting Diode，简称OLED)显示面板时，显示面板中的阵列基板可以包括晶体管(例如薄膜晶体管)，与晶体管的漏极电连接的阳极，还包括阴极和有机材料功能层。有机材料功能层至少包括发光层，进一步还可以包括电子传输层和空穴传输层，在此基础上为了能够提高电子和空穴注入发光层的效率，还可以包括设置在阴极与电子传输层之间的电子注入层，以及设置在阳极与空穴传输层之间的空穴注入层。基于此，显示面板还包括封装层，该封装层可以是薄膜封装也可以是基板封装。
在本发明实施例提供的触摸屏中，由于被第二触控电极102包裹的第一触控电极部分的形状为圆形或椭圆形，因此被第二触控电极102包裹的第一触控电极101与第二触控电极102之间的第一间隙103的内侧也是闭合或近似闭合的圆形或椭圆形，因而当光照射到第一间隙103的内侧时可使反射回来的光不具有规律性，从而在一定程度上可改善图1a和图1b所示的实施例中由于触控电极之间的沟槽规律性反光而导致的消影问题。此外，采用上述的包裹方式设计第一触控电极101和第二触控电极102，相对图1a和图1b所示的实施例可大大增加第一触控电极101和第二触控电极102的相对面积，从而可有效提高触控信号量，增加触控性能。
考虑到外置式触摸屏具有工艺简单、制造成本低等优点，因此，优选触摸屏为外置式触控摸屏，即：触控电极层10设置在显示面板的外侧。
例如，在显示面板为液晶型显示面板的情况下，即，如图10a所示，在显示面板01包括阵列基板40、对置基板(例如彩膜基板)50以及位于阵列基板40和对置基板50之间的液晶层60的情况下，本发明的至少一个实施例提供的触摸屏还可以包括设置在靠近阵列基板40一侧的下偏光片80、以及设置在靠近对置基板50一侧的上偏光片70，例如，触控电极层10设置在对置彩膜基板50与上偏光片70之间。当然，对置基板50也可以为其它未设置彩色滤光层的基板，例如透明基板，本发明实施例包括但不限于此。
例如，如图10b所示，触摸屏还可以包括保护基板90，触控电极层10还可以设置在保护基板90和显示面板01之间，且触控电极层10与保护基板90接触。例如，保护基板90可以为玻璃基板，当然也可以为石英基板或塑料基板等，本发明实施例包括但不限于这些方式。即：可以先在保护基板90上制作形成触控电极层10，然后进行保护基板90、显示面板01等的组装工艺，并使形成在保护基板90上的触控电极层10靠近显示面板01设置。
或者，例如，如图10c所示，可以先在薄膜20上形成触控电极层10，然后将形成有触控电极层的薄膜20贴覆在保护基板90上，最后进行保护基板90、显示面板01等的组装工艺，并使形成在保护基板90上的触控电极层10靠近显示面板01设置。
以上所述仅是本发明的示范性实施方式，而非用于限制本发明的保护范围，本发明的保护范围由所附的权利要求确定。
