具体实施方式
下面介绍的是本发明的多个可能实施例中的一些，旨在提供对本 发明的基本了解，并不旨在确认本发明的关键或决定性的要素或限定所要保护的范围。容易理解，根据本发明的技术方案，在不变更本发明的实质精神下，本领域的一般技术人员可以提出可相互替换的其他实现方式。因此，以下具体实施方式以及附图仅是对本发明的技术方案的示例性说明，而不应当视为本发明的全部或者视为对本发明技术方案的限定或限制。
在以下详细描述中，参考附图，该附图形成详细描述的一部分，并且通过其中可实践本发明的说明性具体实施例来示出。对此，参考描述的图的取向来使用方向术语，例如“顶”、“底”、“左”、“右”、“上”、“下”等。因为实施例的部件可被定位于若干不同取向中，为了图示的目的使用方向术语并且方向术语绝非限制。应当理解的是，可以利用其他实施例或可以做出逻辑改变，而不背离本发明的范围。因此以下详细描述不应当在限制的意义上被采用，并且本发明的范围由所附权利要求来限定。
关于形成或定位在表面“之上或之下”的部分、元件或材料层使用的词语“之上或之下”可以在本文被用于表示该部分、元件或材料层被定位(例如放置、形成、沉积等)为“间接在”所暗示的表面上或下，而具有被布置在所暗示的表面和该部分、元件或材料层之间的一个或多个附加部分、元件或层；或者表示该部分、元件或材料层“直接在”暗示的表面上或下定位(例如放置、形成、沉积等)，例如与其直接接触。
在附图中，各个膜层的尺寸和形状并不反映真实的比例，其目的只是在于示意说明本发明的实施例的FIC电容触摸屏的各个膜层的基本结构和形状。并且，在附图中，为了方便描述，仅给出了FIC电容触摸屏的局部亚像素单元(6行×6列)对应的结构示意图，本领域技术人员根据以下教导和启示可以类推得出FIC电容触摸屏的所有像素对应的结构设置。
参见图1，为FIC电容触摸屏的互电容式触控电极的局部构图示意图。发射电极Tx(Tx1-Tx10)与接收电极Rx(Rx1、Rx2)的布图不考虑阵列基板上的亚像素单元的排列布置，也不考虑其在阵列基板上的正投影是否覆盖阵列基板上的栅线和数据线。因此，在电容触摸屏工作时(例如像素充电电容信号)，触控电极的电容信号会容易受到 尤其是数据线的干扰，产生误触控信号，也即出现触摸误报点。
图2所示为按照本发明一实施例的阵列基板的基本结构示意图。本发明实施例的FIC电容触摸屏设置有阵列基板100，其主要地包括交叉排列的若干数据线130和若干栅线120、按阵列排布的多个红(R)、绿(G)、蓝(B)亚像素单元110。其中，每个亚像素单元110通过薄膜晶体管TFT连接数据线130，TFT通过栅线120控制。数据线130置于相邻两列的亚像素单元110之间，并且多条数据线130之间基本平行排列；栅线120置于相邻两行的亚像素单元110之间，并多条栅线120之间基本平行排列。在工作时，数据线130、栅线120上需要偏置信号，从而使相应的亚像素单元110被控制偏置信号，进而控制相对设置的液晶层的对应亚像素。
需要说明的是，在本发明实施例中，亚像素单元110按行排列的方向定义为x方向，按列排列的方向定义为y方向。需要理解的是，“行”与“列”是相对的位置概念，它们是可以互换的。
阵列基板100的数据线130、栅线120、亚像素单元110可以构图形成在玻璃基板上，其可以相向液晶层(图中未示出)而设置。
图3所示为按照本发明一实施例的FIC电容触摸屏的触控电极的分层结构示意图，其中图3(a)为按行排列的线状电容电极，图3(b)主要为电容电极块。图4所示为图3实施例的FIC电容触摸屏的触控电极的俯视图。图5所示为图3实施例的FIC电容触摸屏的触控电极置于图2实施例的阵列基板上的俯视图。图6所示为图3实施例的触控电极在TFT阵列基本上的正投影示意图，其中图6(a)为线状电容电极在TFT阵列基本上的正投影示意图，图6(b)为电容电极块在TFT阵列基本上的正投影示意图。
以下结合图1至图6对本发明实施例的FIC电容触摸屏进行详细说明，尤其说明本发明实施例的FIC电容触摸屏的触控电极的设置。
在该实施例中，FIC电容触摸屏的触控电极为两层布线设置，其第一层布线为如图3(b)所示的电容电极块310，用于形成触控电容的第一电容电极300；其第二层布线为如图3(a)所示的线状电容电极210，用于形成触控电容的第二电容电极200。以6行×6列的亚像素单元示例进行说明，36个电容电极块310对应图2所示的亚像素单元110的排列方式进行排列，电容电极块310逐一对应每个亚像素单元 110而设置，例如，按照6行×6列等间距地排列，这样每个电容电极块310在阵列基板100上的正投影将落在相应的一亚像素单元110上。每个电容电极块310具有相同的形状和尺寸，在该实施例中，电容电极块310的尺寸对应小于或等于亚像素单元110尺寸，这样，电容电极块310的面积对应小于或等于亚像素单元110面积，每个电容电极块310在阵列基板100上的正投影落于相应的一亚像素单元110的内部，而不会超出亚像素单元110的范围。将理解，电容电极块310的行间距和列间距分别受阵列基板100上的亚像素单元110的行间距和列间距影响，并且也分别受其在y方向和x方向的尺寸大小影响。
需要说明的是，在本发明中，正投影是指垂直于阵列基板进行投影。在阵列基板上的正投影相应地用虚线示意。
在本发明一实施例中，某一区域的若干电容电极块310可以被一条或多条连接线320连接在一起以形成一触控单元的第一电容电极。如图3(b)所示，连接线320可以在x方向或在y方向设置在两个电容电极块310之间。若干连接在一起的电容电极块310通过一引线330引出，引线330可以按y方向设置，其位于相邻两列的电容电极块310之间，通过引线330，可以同时向若干电容电极块310偏置信号。
FIC电容触摸屏的触控电极的另一层布线如图3(a)所示，其为线状电容电极210，多个线状电容电极210在该实施例中平行布置，每个线状电容电极210在阵列基板100上的正投影是位于相邻两行的亚像素单元110之间(如图6(a)所示)。如图5所示，在FIC电容触摸屏的触控电极的两侧布线叠加在一起上时，每个线状电容电极210是对应设置相邻两行电容电极块310之间。多个线状电容电极210通过引线220引出，引线220垂直线状电容电极210设置，通过引线220，可以同时向其连接的多条线状电容电极210偏置信号。
以互电容式触控电极为示例，某一区域的若干电容电极块310被连接线320连接在一起构成一触控单元的发射电极Tx，并通过引线330引出；一线状电容电极210对应设置在上述若干电容电极块310的行之间(如图4所示)，构成一个或多个触控单元的共同的接收电极Rx。Tx发射信号，Rx接收信号，形成互电容，实现触控功能。在如图4所示的示例中，形成了3发射电极Tx，其中2行6列电容电极块310被连接在一起构成某一触控单元的一个Tx，2行4列电容电极块310被 连接在一起构成又一触控单元的一个Tx，2行2列电容电极块310被连接在一起构成还一触控单元的一个Tx，它们分别通过不同的引线330引出，需要理解是，每个发射电极Tx所包括的电容电极块310个数不是限制性的，也即连接在一起的电容电极块310的个数不是限制性的，其可以根据具体触控精度要求进行设置。
以自电容式触控电极为示例，某一区域的若干电容电极块310被连接线320连接在一起构成一触控单元的一电容电极，并通过引线330引出；一线状电容电极210对应设置在上述若干电容电极块310的行之间(如图4所示)，构成触控单元的又一电容电极。线状电容电极210接地GND。需要理解是，连接在一起的电容电极块310的个数不是限制性的，其可以根据具体触控精度要求进行设置。
用于形成触控电极的第一电极300和第二电极200是可以分层地构图形成在同一基板上，该基板可以置于阵列基板100的上方，也可以置于阵列基板100的下方。在一优选实施例中，用于形成触控电极的基板是置于阵列基板100的上方，并且触控电极的第一电极300和第二电极200相向液晶层设置，液晶层位于该用于形成触控电极的基板与阵列基板100之间，彩色滤光片CF进一步置于触控电极的上方，这样，触控电极是形成液晶层与彩色滤光片之间。当然，根据本领域的常识可知，在各个层之间需要设置必要的绝缘层，在液晶层与其它层之间需要设置必要的平坦层。可替代地，第一电极和第二电极可以直接被制作在所述阵列基板的衬底上，并且位于所述衬底中与栅线和数据线相反的一侧。图5示出了触控电极通过ITO等透明电极形成时，触控电极置于图2实施例的阵列基板上方的俯视图，结合图6所示，在该实施例中，每个电容电极块310对应亚像素单元110而设置，其投影落于亚像素单元110上并且不覆盖数据线130，这样可以有效减小数据线130对作为触控电极的电容电极块310的信号干扰，从而FIC电容触摸屏的减少触摸误报点，也有利于提高其良率。
在一实施例中，如图5和图6(b)所示，第一电极300中的引线330对应阵列基板100上的数据线130设置，也即，引线330在阵列基板100上的正投影的位置基本与阵列基板100上的数据线130的位置重叠，这样，有利于提高FIC电容触摸屏的开口率。在其他实施例中，为进一步减少数据线130对第一电极300的信号干扰，引线330也可 以相对阵列基板100上的数据线130错开设置，也即，引线330在阵列基板100上的正投影的位置基本与阵列基板100上的数据线130的位置基本错开(图中未示出)，这样，牺牲一定的开口率进一步减少对触控电容的信号干扰。
在一实施例中，如图5和图6(a)所示，第二电极200中的线状电容电极210可以相对阵列基板100上的栅线120错开设置，也就是说，线状电容电极210在阵列基板100上的正投影的位置基本与阵列基板100上的栅线120的位置基本错开，这样，有利于减少栅线的信号对线状电容电极210的信号干扰(虽然非常小)。在其他实施例中，第二电极200中的线状电容电极210也可以对应阵列基板100上的栅线120设置，也就是说，线状电容电极210在阵列基板100上的正投影的位置基本与阵列基板100上的栅线120的位置重叠(图中未示出)，这样，有利于提高FIC电容触摸屏的开口率。
同样地，第二电极200中的引线220在阵列基板100上的正投影的位置基本与阵列基板100上的栅线120的位置重叠或错开，其是可以根据具体使用需求而选择设置的。
以上实施例的FIC电容触摸屏中，电容电极块相对阵列基板上的数据线错开设置，作为对触控电极的电容产生主要信号干扰的数据线将对电容电极块的信号干扰大大减小，因此，避免出现触摸误报点，提高了FIC电容触摸屏的良率，用户使用体验更好。需要理解的是，不管是在自电容式还是在互电容式中，都能实现以上技术效果。
以上实施例的FIC电容触摸屏可以进一步与驱动IC等部件组装形成显示装置，该显示装置可以应用于各种类型的电子设备中。
以上例子主要说明了本发明的FIC电容触摸屏。尽管只对其中一些本发明的实施方式进行了描述，但是本领域普通技术人员应当了解，本发明可以在不偏离其主旨与范围内以许多其他的形式实施。因此，所展示的例子与实施方式被视为示意性的而非限制性的，在不脱离如所附各权利要求所定义的本发明精神及范围的情况下，本发明可能涵盖各种的修改与替换。
