技术领域

背景技术
随着显示技术的飞速发展，触摸屏(Touch Screen Panel)已经逐渐遍及人们的生活中。

附图中各膜层的形状和尺寸不反映其真实比例，目的只是示意说明本公开文本内容。
本公开文本实施例提供的一种触摸屏，如图1-图6所示，包括：相互 绝缘的多个扇形的第一触摸感测电极1(图1-图6分别示出6个第一触摸感测电极1)和与各第一触摸感测电极1相互绝缘的多条相互绝缘且互不重叠的第二触摸感测电极2(图1-图6分别示出6条第二触摸感测电极2)；其中，
多个扇形的第一触摸感测电极1排列成一圆形；每条第二触摸感测电极2为以各第一触摸感测电极1排列成的圆形同心设置的非闭合的圆环形。
本公开文本实施例提供的上述触摸屏，可以通过第一触摸感测电极确定角度变量并通过第二触摸感测电极确定半径变量来确定触点位置，与现有的两层异面相交的条状电极的触控结构相比，可以降低对触控芯片的信号稳定性和判断触点位置的解析能力的要求，更加适用于诸如圆形的异形触摸屏。
在具体实施时，在本公开文本实施例提供的上述触摸屏中，如图1-图6所示，还可以包括：与各第一触摸感测电极1一一对应且电性连接的多条相互绝缘的第一触摸感测电极线3、与各第二触摸感测电极2一一对应且电性连接的多条相互绝缘且沿半径方向延伸的第二触摸感测电极线4、与各第二触摸感测电极线4一一对应且电性连接的多条相互绝缘的第三触摸感测电极线5以及触控芯片6；其中，各第一触摸感测电极1通过对应的第一触摸感测电极线3与触控芯片6电性连接，各第二触摸感测电极2通过对应的第二触摸感测电极线4和对应的第三触摸感测电极线5与触控芯片6电性连接。
在具体实施时，在本公开文本实施例提供的上述触摸屏中，如图1-图3所示，各第一触摸感测电极1和各第二触摸感测电极2可以同层设置，即各第一触摸感测电极1的图形和各第二触摸感测电极2的图形是采用同一材料通过同一次构图工艺形成的，这样，可以简化触摸屏的制作工艺，降低触摸屏的制作成本，减薄触摸屏的整体厚度；或者，如图4-图6所示，各第一触摸感测电极1和各第二触摸感测电极2也可以异层设置，可以在各第一触摸感测电极1所在膜层与各第二触摸感测电极2所在膜层之间设置绝缘层，各第一触摸感测电极1和各第二触摸感测电极2通过绝缘层相 互绝缘；在此本公开文本不对第一触摸感测电极1和第二触摸感测电极2是否同层设置做限定。
在具体实施时，在本公开文本实施例提供的上述触摸屏中，如图1-图3所示，各第一触摸感测电极1和各第二触摸感测电极2同层设置；为了保证各第一触摸感测电极1与各第二触摸感测电极2相互绝缘，每个第一触摸感测电极1，可以包括：与各第二触摸感测电极2互不重叠的多个沿半径方向排列的第一触摸感测子电极10，每个第一触摸感测电极1包含的各第一触摸感测子电极10组成一扇形。在一个实施例中，触摸屏还可以包括：用于电性连接每个第一触摸感测电极1中相邻的两个第一触摸感测子电极10的第一电性桥7；各第一电性桥7与各第二触摸感测电极2相互绝缘设置。具体地，在一种实施方式中，第一电性桥7与第二触摸感测电极2之间可以设置有绝缘层，第一电性桥7通过位于第一触摸感测子电极10正上方且贯穿该绝缘层的过孔与第一触摸感测子电极10电性连接。
在具体实施时，在本公开文本实施例提供的上述触摸屏中，如图1-图3所示，在各第一触摸感测电极1和各第二触摸感测电极2同层设置时，为了保证各第一触摸感测电极1和与各第二触摸感测电极2电性连接的第二触摸感测电极线4之间相互绝缘，以保证触摸屏的正常工作，可以将第二触摸感测电极线4设置于相邻的两个第一触摸感测电极1之间的间隔处。
需要说明的是，在本公开文本实施例提供的上述触摸屏中，在各第一触摸感测电极和各第二触摸感测电极异层设置时，与各第二触摸感测电极电性连接的第二触摸感测电极线一般与各第二触摸感测电极同层设置，即各第二触摸感测电极线和各第一触摸感测电极异层设置，因此，如图4-图6所示，各第二触摸感测电极线4在各第一触摸感测电极1的正投影可以位于相邻的两个第一触摸感测电极1之间的间隔处，或者，各第二触摸感测电极线与各第一触摸感测电极之间也可以具有重叠区域，在此不做限定。
在具体实施时，在本公开文本实施例提供的上述触摸屏中，如图1和图4所示，各第二触摸感测电极2的非闭合的圆环的开口沿所述圆形的径 向方向对准，即各第二触摸感测电极2在同一角度位置处设置开口，并且，各第二触摸感测电极2的一端与对应的第二触摸感测电极线4电性连接，此时，无论各第一触摸感测电极1和各第二触摸感测电极2为如图1所示的同层设置的结构，还是各第一触摸感测电极1和各第二触摸感测电极2为如图4所示的异层设置的结构，都可以避免各第二触摸感测电极线4和除与该第二触摸感测电极线对应的第二触摸感测电极2之外的其他各第二触摸感测电极2电性连接而影响触摸屏的正常工作。需要指出，本文中所说的开口“对准”，并非是严格指开口的中心位于同一直线上，只要开口的中心大体地围绕同一直线延伸即可。
在具体实施时，在本公开文本实施例提供的上述触摸屏中，如图2、图3、图5和图6所示，各第二触摸感测电极2的非闭合的圆环的开口的排列方向沿圆形的径向方向不对准，即各第二触摸感测电极2在至少两个角度位置处设置开口；由于各第二触摸感测电极2和各第二触摸感测电极线4一般同层设置，因此，为了避免各第二触摸感测电极线4和除与该第二触摸感测电极线对应的第二触摸感测电极2之外的其他各第二触摸感测电极2电性连接而影响触摸屏的正常工作，需要各第二触摸感测电极线4和除与该第二触摸感测电极线对应的第二触摸感测电极2之外的其他各第二触摸感测电极2之间互不重叠，每条第二触摸感测电极2，如图2和图5所示，可以包括：与各第二触摸感测电极线4互不重叠的多条沿圆周方向排列的第二触摸感测子电极20；为了实现每条第二触摸感测电极2中的各第二触摸感测子电极20之间电性连接，本公开文本实施例提供的上述触摸屏，如图2和图5所示，还可以包括：用于电性连接每条第二触摸感测电极2中相邻的两条第二触摸感测子电极20的第二电性桥8；各第二电性桥8与各第二触摸感测电极线4相互绝缘设置；具体地，第二电性桥8与第二触摸感测电极线4之间可以设置有绝缘层，第二电性桥8通过位于各第二触摸感测子电极20正上方且贯穿该绝缘层的过孔分别与各第二触摸感测子电极20电性连接。
在具体实施时，在本公开文本实施例提供的上述触摸屏中，如图2、 图3、图5和图6所示，各第二触摸感测电极2的非闭合的圆环的开口沿圆形的径向方向不对准，即各第二触摸感测电极2在至少两个角度位置处设置开口；由于各第二触摸感测电极2和各第二触摸感测电极线4一般同层设置，因此，为了避免各第二触摸感测电极线4和除与该第二触摸感测电极线对应的第二触摸感测电极2之外的其他各第二触摸感测电极2电性连接而影响触摸屏的正常工作，需要各第二触摸感测电极线4和除与该第二触摸感测电极线对应的第二触摸感测电极2之外的其他各第二触摸感测电极2之间互不重叠，每条第二触摸感测电极线4，如图3和图6所示，可以包括：与各第二触摸感测电极2互不重叠的多条沿半径方向排列的第二触摸感测子电极线40；为了实现每条第二触摸感测电极线4中的各第二触摸感测子电极线40之间电性连接，本公开文本实施例提供的上述触摸屏，如图3和图6所示，还可以包括：用于电性连接每条第二触摸感测电极线4中相邻的两条第二触摸感测子电极线40的第三电性桥9；各第三电性桥9与各第二触摸感测电极2相互绝缘设置。具体地，第三电性桥9与第二触摸感测电极2之间可以设置有绝缘层，第三电性桥9通过位于各第二触摸感测子电极线40正上方且贯穿该绝缘层的过孔分别与各第二触摸感测子电极线40电性连接。
当然，在本公开文本实施例提供的上述触摸屏中，在各第二触摸感测电极的开口的排列方向至少与两条半径相互平行，即各第二触摸感测电极在至少两个角度位置处设置开口时，也可以将各第二触摸感测电极线与对应的第三触摸感测电极线之间通过电性桥的方式电性连接，在此不做限定。
可选地，在本公开文本实施例提供的上述触摸屏中，如图1和图4所示，每条非闭合的圆环形的第二触摸感测电极2的两端分别为第一端和第二端；一部分第二触摸感测电极2的第一端与对应的第二触摸感测电极线4相连，另一部分第二触摸感测电极2的第二端与对应的第二触摸感测电极线4相连。这里，可以认为第一端为沿着顺时针方向在非闭合的圆环的上游的一端，第二端为沿着顺时针方向在非闭合的圆环的下游的一端。这 样，可以使至少两条第二触摸感测电极2上的电流的方向相反，方向相反的电流产生的磁场的方向相反，可以相互抵消EMI和EMC干扰，从而可以降低触摸屏在实现触控功能时的干扰，提高触摸屏的触控精准度。
进一步地，在本公开文本实施例提供的上述触摸屏中，如图2、图3、图5和图6所示，可以将通过第一端与对应的第二触摸感测电极线4相连的第二触摸感测电极2和通过第二端与对应的第二触摸感测电极线4相连的第二触摸感测电极2间隔排列，即相邻的两条第二触摸感测电极2上的电流的方向相反，方向相反的电流产生的磁场的方向相反，可以相互抵消EMI和EMC干扰，从而可以最大限度地降低触摸屏在实现触控功能时的干扰，提高触摸屏的触控精准度。
可选地，在本公开文本实施例提供的上述触摸屏中，为了统一触摸屏的触控精度，提高触摸屏的触控精准度，可以将各第一触摸感测电极的面积设置为相等。
可选地，在本公开文本实施例提供的上述触摸屏中，为了统一触摸屏的触控精度，提高触摸屏的触控精准度，可以将各相邻的两条第二触摸感测电极设置为半径之差相等。
在具体实施时，本公开文本实施例提供的上述触摸屏可以应用于可显示画面的触摸屏，即触摸屏包括显示区域和包围显示区域的边框区域；或者，本公开文本实施例提供的上述触摸屏也可以应用于非显示画面的触摸板，在此不做限定。
具体地，在本公开文本实施例提供的上述触摸屏应用于可显示画面的触摸屏时，如图1-图6所示，可以将各第一触摸感测电极1、各第二触摸感测电极2和各第二触摸感测电极线4设置于触摸屏的显示区域(即如图1-图6所示的各第一触摸感测电极排列成的圆形所在区域)内，为了不影响触摸屏的正常显示，可以将各第一触摸感测电极1、各第二触摸感测电极2和各第二触摸感测电极线4设置为透明状，具体地，各第一触摸感测电极1、各第二触摸感测电极2和各第二触摸感测电极线4的材料可以为透明导电氧化物(Transparent Conducting Oxide,TCO)，例如，氧化铟锡 (Indium Tin Oxides,ITO)、氧化铟锌(Indium Zinc Oxides,IZO)或氧化铟镓锌(Indium Gallium Zinc Oxides,IGZO)等，在此不做限定。可以将各第一触摸感测电极线3、各第三触摸感测电极线5和触控芯片6设置于触摸屏的边框区域(即包围显示区域的区域)内，具体地，各第一触摸感测电极线3和各第三触摸感测电极线5的材料可以为不透明的金属，在此不做限定。
需要说明的是，在本公开文本实施例提供的上述触摸屏应用于可显示画面的触摸屏时，第一电性桥、第二电性桥和第三电性桥位于触摸屏的显示区域内，在第一电性桥、第二电性桥和第三电性桥的材料为金属时，为了避免第一电性桥、第二电性桥和第三电性桥漏光而影响触摸屏的显示效果，可以将各第一电性桥、各第二电性桥和各第三电性桥设置于触摸屏中黑矩阵所在区域内，该黑矩阵为触摸屏包含的显示面板中用于遮挡显示用信号线(例如栅线、数据线)的黑矩阵。当然，第一电性桥、第二电性桥和第三电性桥的材料也可以为TCO，在此不做限定。
在具体实施时，本公开文本实施例提供的上述触摸屏可以应用于手表的表盘，将第一触摸感测电极线和第三触摸感测电极线设置在手表的边框区域内，不仅可以避免在手表的圆心处设置电极线引起的视觉效果不良，并且，由于手表的显示区域中靠近边框区域的部分设置有用于标识时间的数字，即使第一触摸感测电极线和第三触摸感测电极线从边框区域延伸至显示区域的边缘，也能被标识时间的数字遮挡，不仅可以减小第一触摸感测电极线和第三触摸感测电极线引起的视觉效果不良，还可以使手表实现窄边框设计。
基于同一公开文本构思，本公开文本实施例还提供了一种显示装置，包括本公开文本实施例提供的上述触摸屏，该显示装置可以为：手机、平板电脑、电视机、显示器、笔记本电脑、数码相框、导航仪等任何具有显示功能的产品或部件。该显示装置的实施可以参见上述触摸屏的实施例，重复之处不再赘述。
