【具体实施方式】
下面将结合本发明实施例中的附图,对本发明所提供的示例性的实施例的技术方案进行清楚、完整地描述。
请参阅图1所示,本发明实施例的导电层结构10设置于由玻璃或薄膜材料制成的基板的表面,包括多个第一电极图案Px以及多个矩形的第二电极图案Py(不限于图中所示的四个),其中,多个第二电极图案Py呈矩形阵列排布,多个第一电极图案Px环绕所述呈矩形阵列排布的多个第二电极图案Py的四周,每一个第一电极图案Px包括一个第一子电极图案Px1和一个第二子电极图案Px2,第一子电极图案Px1临近第二子电极图案Px2的第一侧边X设置有直角结构,第二子电极图案Px2临近第一子电极图案Px1的第二侧边Y也设置有直角结构,并且第一侧边X和第二侧边Y相啮合,使得第一子电极图案Px1和第二子电极图案Px2配合形成的第一电极图案Px呈矩形设置。
其中,第一子电极图案Px1和第二子电极图案Px2均为“L”型结构,即,每一第一电极图案Px1具有六条边Lx1、Lx2、Lx3、Lx4、Lx5、Lx6,每一第二子电极图案Px2也具有六条边Ly1、Ly2、Ly3、Ly4Ly5、Ly6,并且边Lx4、Lx5、Lx6构成第一侧边X,边Lx4和边Lx5以及边Lx5和边Lx6分别构成第一侧边X的两个直角结构,边Ly4、Ly5、Ly6第二侧边Y,边Ly4和边Ly5以及边Ly5和边Ly6分别构成第一侧边Y的两个直角结构,边Lx4与边Ly6相邻,边Lx5与边Ly5相邻,边Lx6与边Ly4相邻。
基于此,在行方向上,每一第一电极图案Px的长度等于边Lx2的长度,在列方向上,每一第一电极图案Px的宽度等于边Lx1、Ly3的长度以及两者之间的距离之和。本实施例可以进一步设置每一第一电极图案Px的长度等于每一第二电极图案Py的长度,且每一第一电极图案Px的宽度等于每一第二电极图案Py的宽度。可选地,第一电极图案Px与相邻的第二电极图案Py之间的距离和第一子电极图案Px1与第二子电极图案Px2之间的距离相等。
在本实施例中,呈矩形阵列排布的所述多个第二电极图案Py的行方向上仅设置有两行第一电极图案Px,且分别位于所述呈矩形阵列排布的多个第二电极图案Py的上方和下方,呈矩形阵列排布的所述多个第二电极图案Py的列方向上设置有两列第一电极图案Px,且分别位于所述呈矩形阵列排布的多个第二电极图案Py的左侧和右侧。
其中,位于所述上方的第一电极图案Px向右旋转90°之后,与位于所述右侧的第一电极图案Px相同,位于所述下方的第一电极图案Px向左旋转90°之后,与位于所述左侧的第一电极图案Px相同,且位于所述列方向上的两列所述第一电极图案Px沿第一轴线A对称,且位于行方向上的两行第一电极图案Px沿第二轴线B对称,所述第一轴线A和所述第二轴线B分别为呈矩形阵列排布的所述多个第二电极图案Py在所述列方向和所述行方向上的中轴线。

请进一步结合图2所示,第一电极图案Px和第二电极图案Py分别与大地构成对地的自电容C1。当手指21触摸到触摸屏的盖板22时,由于人体可以等效为大地,手指21与第一电极图案Px或第二电极图案Py之间形成一个电容C2,电容C2与电容C1形成如图3所示的并联电路使得对应的感应单元的电容量增加。基于此,通过检测每个感应单元的电容变化即可判断是否产生触摸事件,并且通过第一电极图案Px和第二电极图案Py在触摸屏上的坐标信息即可判定触摸点的位置。
本实施例的第一电极图案Px相当于在一个感应单元内增加了电极图案之间的接触面积,当手指21在触摸屏的四周边缘滑动时,边缘区域的电极图案之间的电容量变化较小,从一个触摸点滑动到另一个触摸点的电容量 变化符合线性变化,能够精确判定手指21的滑动轨迹。
在此发明目的基础上,本发明实施例还可以设置导电层结构10的第一电极图案Px具有其他结构,例如图4所示,第一子电极图案Px1为可以“E”型结构,第一子电极图案Px1的第一侧边X包括具有直角结构的两个凹口,此时第二子电极图案Px2的第二侧边Y包括具有与两个凹口相啮合的两个凸起,第一侧边X和第二侧边Y相啮合,使得第一子电极图案Px1和第二子电极图案Px2配合呈矩形设置。
本发明还提供一种具有触控功能的液晶显示器,包括显示组件和触控组件,其中,显示组件和触控组件共用公共电极,所述触控组件包括与所述公共电极相对设置的上述导电层结构10。
