Abstract

一种触摸屏及触摸显示装置，其中在相邻触控电极（01）之间的间隙设置有若干隔离电极（02），并且该隔离电极（02）与触控电极（01）相互绝缘。因此在制作时，即使有一个触控电极（01）与相邻的隔离电极（02）发生短路，由于该隔离电极（02）与其它隔离电极（02）之间、以及该隔离电极（02）与其它触控电极（01）之间均是绝缘的，因此这种短路只是将该隔离电极（02）合并为触控电极（01）的一部分，而该隔离电极（02）与其它触控电极（01）还是处于绝缘状态，因此可以极大地降低触摸屏发生短路的风险。

技术领域
本发明涉及触控显示技术领域，尤其涉及一种触摸屏及触摸显示装置。
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。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，外挂式触摸屏是分开生产触摸屏与液晶显示屏(Liquid Crystal Display，LCD)，然后将它们贴合到一起以成为具有触摸功能的液晶显示屏。外挂式触摸屏存在制作成本较高、光透过率较低、模组较厚等缺点。而内嵌式触摸屏是将触摸屏的触控电极内嵌在液晶显示屏内部，从而可以减薄模组整体的厚度，又可以大大降低触摸屏的制作成本，所以受到各大面板厂家的青睐。
目前，现有的内嵌(In cell)式触摸屏主要是利用互电容或自电容的原理实现手指触摸位置的检测。在现有的内嵌式触摸屏中，触控电极的材料一般采用透明导电氧化物，例如氧化铟锡(Indium Tin Oxide，ITO)。但是，由于ITO的光透过率不是100％，而且触控电极的折射率与衬底基板的折射率存在一定的差异，从而导致触控电极与其之间的间隙在视觉上存在一定的差异，由此造成触控电极的图形是肉眼可以识别的。
现有技术中，通常通过减小间隙宽度来避免这种视觉上的差异，但是随着触控电极间隙宽度的减小，在制作时，触控电极之间发生短路的风险就会增大。因此，在保证显示效果的基础上如何降低触摸屏发生短路的风险是本领域技术人员亟需解决的技术问题。
发明内容
本发明实施例提供了一种触摸屏及触摸显示装置，用以实现在保证触摸屏显示效果的基础上降低触摸屏发生短路的风险。
本发明实施例提供的触摸屏，包括若干相互独立且同层设置的触控电极，其中至少在部分相邻触控电极之间的间隙设置有多个彼此独立的隔离电极，所述隔离电极与所述触控电极同层且相互绝缘。

具体实施方式
下面结合附图，对本发明实施例提供的触摸屏及触摸显示装置的具体实施方式进行详细地说明。
附图中各区域的大小、形状不反映真实比例，其目的只是示意说明本发明内容。
本发明实施例提供了一种触摸屏，如图1a和图1b所示，其包括若干相互独立且同层设置的触控电极01，其中至少在部分相邻触控电极01之间的间隙设置有多个彼此独立的隔离电极02，隔离电极02与触控电极01同层且相互绝缘。
根据本发明实施例提供的上述触摸屏，在相邻触控电极之间的间 隙设置有若干隔离电极，并且该隔离电极与触控电极相互绝缘。因此在制作时，即使有一个触控电极与相邻的隔离电极发生短路，由于该隔离电极与其它隔离电极之间、以及该隔离电极与其它触控电极之间均是绝缘的，因此这种短路只是将该隔离电极合并为触控电极的一部分，而该隔离电极与其它触控电极还是处于绝缘状态，因此可以极大地降低触摸屏发生短路的风险。
另外，在本发明实施例提供的上述触摸屏中，由于隔离电极与触控电极同层设置，因此隔离电极与触控电极的制作可以通过一次构图工艺同时形成，而不需要增加工艺步骤，仅需变更构图图形就可以实现。
具体地，在本发明实施例提供的上述触摸屏中，可以根据实际情况仅在一些预设区域内的相邻触控电极之间的间隙中设置隔离电极，例如容易发生短路的区域等。
较佳地，为了保证均匀性，以及降低整个触摸屏发生短路的风险，在本发明实施例提供的上述触摸屏中，如图1b所示，在所有相邻触控电极01之间的间隙中设置隔离电极02。
进一步地，在本发明实施例提供的上述触摸屏中，如图1c所示，为了降低整个触摸屏发生短路的风险，只要是同层设置的触控电极01之间的间隙均可以设置隔离电极02，而与相邻触控电极01之间的形状无关。
具体地，在具体实施时，本发明实施例提供的上述触摸屏，可以是自电容式触摸屏也可以是互电容式触摸屏，在此不作限定。当触摸屏为互电容式触摸屏时，触控电极可以是触控感应电极，也可以是触控驱动电极，还可以是触控感应电极和触控驱动电极，在此不作限定。
具体地，在具体实施时，本发明实施例提供的上述触摸屏中，触控电极的材料可以是任何透明导电材料，在此不作限定。具体地，在具体实施时，触控电极的材料可以为透明导电氧化物、石墨烯，或金属网络等。
进一步地，在发明实施例提供的上述触摸屏中，所有隔离电极的大小和形状可以相同，也可以不同，在此不作限定。较佳地，为了制作方便，所有隔离电极的大小和形状均相同。
具体地，在具体实施时，在本发明实施例提供的上述触摸屏中， 隔离电极的形状可以为规则的形状，例如矩形、三角形或圆形等，当然也可以为不规则的形状，在此不作限定。较佳地，为了制作方便，隔离电极的形状设置为规则的形状。
进一步地，在本发明实施例提供的上述触摸屏中，所有隔离电极可以均匀分布于相邻触控电极之间的间隙处，也可以随机分布于相邻触控电极之间的间隙处，在此不作限定。较佳地，隔离电极均匀分布于相邻触控电极之间的间隙处。
较佳地，在本发明实施例提供的上述触摸屏中，为了便于制作以及保证显示上的均匀性，如图2a和图2b所示，相邻的隔离电极02与触控电极01的相对侧边平行。即要求隔离电极02与触控电极01相邻的侧边要与该相邻的触控电极的对应侧边互相平行，而对于隔离电极不与触控电极相邻的侧边的形状在此不作限定。
具体地，在具体实施时，在本发明实施例提供的上述触摸屏中，如图2b所示，隔离电极02与相邻的触控电极01之间的间隙宽度S1小于30微米，在此不作限定。
较佳地，为了避免人眼可以辨识出触控电极与隔离电极之间的间隙，在本发明实施例提供的上述触摸屏中，将隔离电极与相邻的触控电极之间的间隙宽度设置为小于10微米。
进一步地，在本发明实施例提供的上述触摸屏中，将所有的隔离电极与相邻触控电极之间的间隙宽度设置为相等，在此不作限定。
进一步地，在本发明实施例提供的上述触摸屏中，为了便于制作以及保证显示上的均匀性，如图2a和图2b所示，相邻两个隔离电极02的相对侧边平行。
具体地，在具体实施时，在本发明实施例提供的上述触摸屏中，如图2b所示，所有相邻两个隔离电极02之间的间隙宽度S2小于30微米，在此不作限定。
较佳地，为了避免人眼可以辨识出隔离电极与隔离电极之间的间隙，在本发明实施例提供的上述触摸屏中，将相邻两个隔离电极02之间的间隙宽度设置为小于10微米。
进一步地，在本发明实施例提供的上述触摸屏中，将所有的隔离电极之间的间隙宽度设置为相等，在此不作限定。
较佳地，在具体实施时，在本发明实施例提供的上述触摸屏中， 将隔离电极与相邻触控电极之间的间隙宽度以及相邻隔离电极之间的间隙宽度设置为相等。
具体地，在具体实施时，在本发明实施例提供的上述触摸屏中，触控电极之间的间隙中设置的隔离电极越多，发生短路的风险就越小。具体地，这是因为，当隔离电极的数量较多时，其相应的尺寸就会越小，所以从概率上讲，更为不容易造成触摸电极的短路。在实际产品设计和生产过程中，这是较为普遍的处理措施。
因此，在具体实施时，可以通过减小隔离电极的尺寸来增加隔离电极的数量，但是这样隔离电极的尺寸越小，制作难度就越大。或者也可以通过占用触控电极的面积来增加隔离电极的数量，但是这样又会减小触控电极的数量，进而影响触控灵敏度。因此在具体实施时，可以根据实际情况确定隔离电极的数量和尺寸。
在具体实施时，在本发明实施例提供的上述触摸屏中，如图3所示，隔离电极02在第一方向Y上的宽度小于2000微米，并且在第二方向X上的宽度小于1000微米；其中，第一方向Y垂直于第二方向X。在具体实施时，一般选取相邻触控电极之间的间隙的延伸方向为第一方向Y。
较佳地，在具体实施时，在本发明实施例提供的上述触摸屏中，当第一方向为相邻触控电极之间的间隙的延伸方向时，将隔离电极在第二方向X上的宽度控制在5微米～20微米之间时效果较佳。
一般在具体实施时，在本发明实施例提供的上述触摸屏中，如图3和图4所示，相邻两个触控电极01的相对侧边平行。
进一步地，在本发明实施例提供的上述触摸屏中，如图3和图4所示，相邻两个触控电极01的相对侧边均为直线或折线。
较佳地，为了降低短路风险，在本发明实施例提供的上述触摸屏中，如图5a和图5b所示，相邻触控电极01之间的间隙设置有至少一列沿该间隙的延伸方向均匀排列的隔离电极02，并且隔离电极02各自的形状为矩形或平行四边形。
较佳地，为了降低短路风险，在本发明实施例提供的上述触摸屏中，如图6所示，隔离电极02的形状为三角形，并且两个隔离电极02形成一个隔离电极组，在每个隔离电极组中，两个隔离电极02的三个对应边分别平行；并且
相邻触控电极01之间的间隙设置有沿该间隙的延伸方向均匀排列的一列隔离电极组。
基于同一发明构思，本发明实施例还提供了一种触摸显示装置，其包括本发明实施例提供的上述触摸屏。该触摸显示装置可以为：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。该触摸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。
根据本发明实施例提供的触摸屏及触摸显示装置，在相邻触控电极之间的间隙设置有若干隔离电极，并且该隔离电极与触控电极相互绝缘。因此在制作时，即使有一个触控电极与相邻的隔离电极发生短路，由于该隔离电极与其它隔离电极之间、以及该隔离电极与其它触控电极之间均是绝缘的，因此这种短路只是将该隔离电极合并为触控电极的一部分，而该隔离电极与其它触控电极还是处于绝缘状态，因此可以极大地降低触摸屏发生短路的风险。
显然，本领域的技术人员可以对本发明进行各种改动和变型而不脱离本发明的精神和范围。这样，倘若本发明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。
