Description

一种液晶显示面板及其制造方法、 显示装置 技术领域
本公开涉及显示技术, 尤其涉及一种液晶显示面板及其制造方法、 显示 装置。 背景技术
目前触控技术作为连接使用者和电子设备的桥梁已经逐渐被应用在手 机、 平板电脑、 自动取款机以及各种包括液晶显示器的电子显示设备上。
根据触控传感器设置位置的不同, 一般可以将现有的具有触控功能的液 晶显示面板分为表面式( on cell )触控面板与内嵌式( in cell )触控面板两种。 目前市场上较常见的为表面式触控面板, 这样一种触控面板通过在显示面板 的表面附加触控结构以实现触控功能, 由于无需对显示面板结构进行改变, 因而易于实现, 但表面式触控面板一般厚度较大, 光透过率也难以保证, 且 多数不能实现多点触控功能。 因此, 业界已逐渐开始将注意力转向具有更薄 厚度与更高光透过率的内嵌式触控面板。
在现有的内嵌式触控面板中, 为了准确获得用户的触控位置, 通常需要 在阵列基板上制作用于触控的 X和 Y坐标判断结构,这些坐标判断结构均是 通过金属线的设计与连接实现的。 由于工艺的因素, 在有金属线的区域需要 留出间距, 金属线区域通常范围较大, 金属线区域范围的扩大将使得显示器 的边框宽度增加; 另一方面, 为了防止光线对金属线所造成的电场影响, 金 属线区域需要用黑矩阵盖住, 这也将在一定程度上影响显示面板的开口率, 现有技术尚难以解决以上问题。 发明内容
本发明的实施例提供一种液晶显示面板及其制造方法、 显示装置, 可以 减小阵列基板上的金属线区域, 从而减小显示器的边框宽度, 提高显示面板 的开口率。
为达到上述目的, 本发明的实施例采用如下技术方案: 本发明实施例的一方面, 提供一种液晶显示面板, 包括: 对盒成型的第 一基板和第二基板, 所述第一基板和所述第二基板之间具有用于支撑液晶盒 厚的第一隔垫物, 其中
所述第一基板靠近所述第二基板一侧的表面还形成有多个第二隔垫物, 所述第二隔垫物的高度小于所述第一隔垫物的高度;
在所述第二隔垫物的表面和所述第二基板的与所述第二隔垫物对应的表 面这两个表面中的一个上, 形成有分离的第一电极和第二电极, 所述第一电 极和所述第二电极具有不同的电位;
在所述第二隔垫物的表面和所述第二基板的与所述第二隔垫物对应的表 面这两个表面中的另一个上, 形成有第三电极, 使得当不进行触控操作时, 所述第三电极不与所述第一电极和所述第二电极相接触;当进行触控操作时, 所述第三电极与所述第一电极和所述第二电极相接触。
本发明实施例的另一方面, 提供一种显示装置, 其包括如上所述的液晶 显示面板。
本发明实施例的又一方面, 提供一种液晶显示面板制造方法, 包括以下 步骤:
在第一基板或第二基板的表面形成第一隔垫物, 且在所述第一基板的表 面形成第二隔垫物, 所述第二隔垫物的高度小于所述第一隔垫物的高度; 在所述第二隔垫物的表面和所述第二基板的与所述第二隔垫物对应的表 面这两个表面中的一个上, 形成分离的第一电极和第二电极;
在所述第二隔垫物的表面和所述第二基板的与所述第二隔垫物对应的表 面这两个表面中的另一个上, 形成第三电极;
将所述第一基板和所述第二基板对盒成型, 使得当不进行触控操作时, 所述第三电极不与所述第一电极和所述第二电极相接触; 而当进行触控操作 时, 所述第三电极与所述第一电极和所述第二电极相接触。
本发明实施例提供的液晶显示面板及其制造方法、 显示装置, 通过在一 块基板的表面形成分离的第一电极和第二电极, 在另一块基板的表面形成与 第一电极和第二电极对应的第三电极, 其中, 第一电极和所述第二电极具有 不同的电位, 且在不进行触控操作时, 第三电极不与第一电极和第二电极相 接触。 当用户进行触控操作时,第三电极将连接并导通第一电极和第二电极, 从而使得第二电极和第三电极的电位改变, 根据电极的电位变化情况即可对 触摸点的坐标进行锁定。 这样一来, 避免了在阵列基板上制作用于测定横纵 坐标的两组金属线中的一组, 可以有效减小阵列基板上的金属线区域, 从而 减小了显示器的边框宽度, 提高了显示面板的开口率。 附图说明

下面将结合本发明实施例中的附图, 对本发明实施例中的技术方案进行 清楚、 完整地描述, 显然, 所描述的实施例仅仅是本发明一部分实施例, 而 不是全部的实施例。 基于本发明中的实施例, 本领域普通技术人员所获得的 所有其他实施例, 都属于本发明保护的范围。
除非另作定义, 此处使用的技术术语或者科学术语应当为本发明所属领 域内具有一般技能的人士所理解的通常意义。 "一个" 、 "一" 或者 "该" 等类似词语也不表示数量限制, 而是表示存在至少一个。 "包括" 或者 "包 含" 等类似的词语意指出现在 "包括" 或者 "包含" 前面的元件或者物件涵 盖出现在 "包括" 或者 "包含" 后面列举的元件或者物件及其等同, 并不排 除其他元件或者物件。 "连接" 或者 "相连" 等类似的词语并非限定于物理 的或者机械的连接, 而是可以包括电性的连接, 不管是直接的还是间接的。 "上" 、 "下" 、 "左" 、 "右" 等仅用于表示相对位置关系, 当被描述对 象的绝对位置改变后, 则该相对位置关系也可能相应地改变。
本发明实施例提供的液晶显示面板, 如图 1所示, 包括: 对盒成型的第 一基板 11和第二基板 12, 该第一基板 11和第二基板 12之间具有用于支撑 液晶盒厚的第一隔垫物 13。
其中, 第一基板 11靠近第二基板 12—侧的表面还形成有多个第二隔垫 物 14, 该第二隔垫物 14的高度 h小于第一隔垫物 13的高度 H。
在第二隔垫物 14的表面和第二基板 12的与第二隔垫物 14对应的表面这 两个表面中的一个上, 形成有分离的第一电极 151和第二电极 152, 该第一 电极 151和第二电极 152具有不同的电位。 作为例子, 在如图 1所示的液晶 显示面板中,是以第一电极 151和第二电极 152形成在第二隔垫物 14的表面 为例进行的说明。
在第二隔垫物 14的表面和第二基板 12的与第二隔垫物 14对应的表面这 两个表面中的另一个上, 形成有第三电极 16, 使得当不进行触控操作时, 第 三电极 16不与第一电极 151和第二电极 152相接触; 当进行触控操作时,第 三电极 16与第一电极 151和第二电极 152相接触。同样参照图 1所示的液晶 显示面板,是以第三电极 16形成在第二基板 12的与第二隔垫物 14对应的表 面为例进行的说明。
本发明实施例提供的液晶显示面板, 通过在一块基板的表面形成分离的 第一电极和第二电极, 在另一块基板的表面形成与第一电极和第二电极对应 的第三电极, 其中, 第一电极和所述第二电极具有不同的电位, 且在不进行 触控操作时, 第三电极不与第一电极和第二电极相接触。 当用户进行触控操 作时, 第三电极将连接并导通第一电极和第二电极, 从而使得第二电极和第 三电极的电位改变,根据电极的电位变化情况即可对触摸点的坐标进行锁定。 这样一来, 避免了在阵列基板上制作用于测定横纵坐标的两组金属线中的一 组,可以有效减小阵列基板上的金属线区域,从而减小了显示器的边框宽度, 提高了显示面板的开口率。
举例来说, 第一电极 151与第二电极 152之间的间距 d例如可以在 4-6 μ m之间。 这样一种尺寸的电极结构可以采用现有的构图工艺处理得到。
第一基板 11可以为阵列基板, 第二基板 12可以为彩膜基板; 或者第一 基板 11可以为彩膜基板, 第二基板 12可以为阵列基板。
在本发明实施例中, 均是以第一基板 11为阵列基板, 第二基板 12为彩 膜基板为例进行的说明, 可以理解, 本发明实施例所提供的液晶显示面板同 样可以采用第二基板 12为阵列基板, 本发明对此并不做限制。
当第一基板 11为阵列基板时, 如图 2所示, 第一基板 11可以包括以矩 阵形式排列的多个像素单元 21、 与各像素单元 21对应的横向排列的多行栅 线 22以及纵向排列的多列数据线 23。
进一步地, 每一个像素单元 21可以对应一个第二隔垫物 14, 并且该第 二隔垫物 14可以位于栅线 22和数据线 23的交叉位置处。这样一来,保证了 第二隔垫物 14的数量, 从而保证了触控的精度, 同时位于栅线 22和数据线 23的交叉位置处的第二隔垫物 14还可以无需增加现有的黑矩阵区域, 有效 保证了液晶显示面板的开口率。
在一个实施例中,第一电极 151例如可以与公共电极层(图 2中未示出) 电连接。 由于公共电极层持续通电,第一电极 151因而可以具有稳定的电位, 在液晶显示面板的实际使用过程中,第二电极 152以及第三电极 16在无触控 操作时均可以处于未通电状态。 这样一来, 当用户进行触控操作时, 位于彩 膜基板 12上的第三电极 16与形成在阵列基板第二隔垫物 14上的第一电极 151和第二电极 152进行导通,使得第二电极 152和第三电极 16均从未通电 状态变为带电状态,从而根据第二电极 152和第三电极 16的两个信号即可确 定触控位置的坐标, 实现了内嵌式触控功能。 作为替代, 第一电极 151也可 以与栅线或者数据线相连, 从而在对栅线或者数据线提供信号时, 也可以使 第一电极 151具有相应的电位, 由于触摸时间通常大于一帧的扫描时间, 因 此, 在触摸所涉及的那一帧时间内, 仍然可以使第一电极 151具备一定的电 位, 从而可以用于确定触控位置的坐标。 这样, 可以无需增加阵列基板上的 走线即可实现内嵌式触控功能, 进一步提高了液晶显示面板的开口率。
本发明实施例提供的内嵌式触控面板可以广泛地适用于例如 AD-SDS
( Advanced-Super Dimensional Switching, 筒称为 ADS, 高级超维场开关) 型、 IPS ( In Plane Switch, 横向电场效应)型或 TN ( Twist Nematic, 扭曲向 列)型等类型的液晶显示装置的生产。 无论上述哪种液晶显示装置都包括对 盒成形的彩膜基板和阵列基板。 不同的是, TN型显示装置的公共电极设置 在彩膜基板上, 像素电极设置在阵列基板上; ADS型显示装置和 IPS型显示 装置的公共电极和像素电极均设置在阵列基板上。
在本发明实施例中是以公共电极和像素电极均设置在阵列基板上为例进 行的说明, 其中, 第二隔垫物 14设置于阵列基板上(如图 2所示), 位于第 二隔垫物 14表面的第一电极 151与设置在阵列基板上的公共电极层电连接。 当第二隔垫物 14设置于彩膜基板上时, 位于第二隔垫物 14表面的第一电极 151 可以与设置在阵列基板上的公共电极层电连接, 此时公共电极和像素电 极设置于不同的基板。
进一步地, 如图 2所示, 位于同一行的第二电极 152均可以与同一条第 二电极线 150相连接, 在本发明实施例中, 第一基板 11为阵列基板, 这样一 来,每一条第二电极线 150对应一个纵轴坐标,从而可以根据第二电极线 150 上的信号确定触控的纵坐标。 同时,位于同一列的第三电极 16均可以与同一 条第三电极线 160相连接, 在本发明实施例中, 第二基板 12为彩膜基板, 该 彩膜基板的结构如图 3所示, 这样一来, 每一条第三电极线 160对应一个横 轴坐标, 从而可以根据第三电极线 160上的信号确定触控的横坐标。 采用这 样一种结构的液晶显示面板, 根据第二电极线 150和第三电极线 160的两个 信号即可确定触控位置的横纵坐标, 实现了内嵌式触控功能。
或者, 如图 4所示, 位于同一列的第二电极 152均可以与同一条第二电 极线 150相连接, 在本发明实施例中, 第一基板 11为阵列基板, 这样一来, 每一条第二电极线 150对应一个横轴坐标, 从而可以根据第二电极线 150上 的信号确定触控的横坐标。 同时,位于同一列的第三电极 16均可以与同一条 第三电极线 160相连接, 在本发明实施例中, 第二基板 12为彩膜基板, 该彩 膜基板的结构如图 5所示, 这样一来, 每一条第三电极线 160对应一个纵轴 坐标, 从而可以根据第三电极线 160上的信号确定触控的纵坐标。 采用这样 一种结构的液晶显示面板, 根据第二电极线 150和第三电极线 160的两个信 号即可确定触控位置的横纵坐标, 实现了内嵌式触控功能。
本发明实施例提供的液晶显示面板, 可以避免在阵列基板上制作用于测 定横纵坐标的两组金属线中的一组, 从而可以有效减小阵列基板上的金属线 区域, 减小了显示器的边框宽度, 提高了显示面板的开口率。
本发明实施例还提供一种液晶显示面板, 如图 6所示, 包括: 对盒成型 的第一基板 11和第二基板 12, 该第一基板 11和第二基板 12之间具有用于 支撑液晶盒厚的第一隔垫物 13。
与前述实施例类似的, 第一基板 11靠近第二基板 12一侧的表面还形成 有多个第二隔垫物 14,该第二隔垫物 14的高度 h小于第一隔垫物 13的高度 H。
与前述实施例不同的是, 在如图 6所示的液晶显示面板中, 是以第三电 极 16形成在第二隔垫物 14的表面, 第一电极 151和第二电极 152形成在第 二基板 12的与第二隔垫物 14对应的表面为例进行的说明。 其中, 第二基板 12对应第二隔垫物 14的表面形成有分离的第一电极 151和第二电极 152,该 第一电极 151和第二电极 152具有不同的电位。
第二隔垫物 14的表面形成有第三电极 16,在不进行触控操作的状态下, 该第三电极 16不与第一电极 151和第二电极 152相接触;当进行触控操作时, 该第三电极 16与第一电极 151和第二电极 152相接触。
本发明实施例提供的液晶显示面板, 通过在一块基板的表面形成分离的 第一电极和第二电极, 在另一块基板的表面形成与第一电极和第二电极对应 的第三电极, 其中, 第一电极和所述第二电极具有不同的电位, 且在不进行 触控操作时, 第三电极不与第一电极和第二电极相接触。 当用户进行触控操 作时, 第三电极将连接并导通第一电极和第二电极, 从而使得第二电极和第 三电极的电位改变,根据电极的电位变化情况即可对触摸点的坐标进行锁定。 这样一来, 避免了在阵列基板上制作用于测定横纵坐标的两组金属线中的一 组,可以有效减小阵列基板上的金属线区域,从而减小了显示器的边框宽度, 提高了显示面板的开口率。
举例来说, 第一电极 151与第二电极 152之间的间距 d例如可以在 4-6 μ m之间。 这样一种尺寸的电极结构可以采用现有的构图工艺处理得到。
第一基板 11可以为阵列基板, 第二基板 12可以为彩膜基板; 或者第一 基板 11可以为彩膜基板, 第二基板 12可以为阵列基板。
在本发明实施例中, 均是以第一基板 11为阵列基板, 第二基板 12为彩 膜基板为例进行的说明, 可以理解, 本发明实施例所提供的液晶显示面板同 样可以采用第二基板 12 为阵列基板, 本发明对此并不做限制。 当第一基板 11为阵列基板时, 如图 7所示, 第一基板 11可以包括以矩阵形式排列的多 个像素单元 21、与各像素单元 21对应的横向排列的多行栅线 22以及纵向排 列的多列数据线 23。
进一步地, 每一个像素单元 21可以对应一个第二隔垫物 14, 并且该第 二隔垫物 14可以位于栅线 22和数据线 23的交叉位置处。这样一来,保证了 第二隔垫物 14的数量, 从而保证了触控的精度, 同时位于栅线 22和数据线 23的交叉位置处的第二隔垫物 14还可以无需增加现有的黑矩阵区域, 有效 保证了液晶显示面板的开口率。
其中, 第一电极 151例如可以与公共电极层电连接。 由于公共电极层持 续通电, 第一电极 151因而可以具有稳定的电位, 在液晶显示面板的实际使 用过程中,第二电极 152以及第三电极 16在无触控操作时均可以处于未通电 状态。 这样一来, 当用户进行触控操作时, 位于彩膜基板 12上的第一电极 151和第二电极 152与形成在阵列基板第二隔垫物 14上的第三电极 16进行 导通,使得第二电极 152和第三电极 16均从未通电状态变为带电状态,从而 根据第二电极 152和第三电极 16的两个信号即可确定触控位置的坐标,实现 了内嵌式触控功能。
本发明实施例提供的内嵌式触控面板可以广泛地适用于例如 AD-SDS ( Advanced-Super Dimensional Switching, 筒称为 ADS, 高级超维场开关) 型、 IPS ( In Plane Switch, 横向电场效应)型或 TN ( Twist Nematic, 扭曲向 列)型等类型的液晶显示装置的生产。 无论上述哪种液晶显示装置都包括对 盒成形的彩膜基板和阵列基板。 不同的是, TN型显示装置的公共电极设置 在彩膜基板上, 像素电极设置在阵列基板上; ADS型显示装置和 IPS型显示 装置的公共电极和像素电极均设置在阵列基板上。
在本发明实施例中是以公共电极和像素电极分别设置在彩膜基板和阵列 基板上为例进行的说明, 其中, 第二隔垫物 14设置于阵列基板上(如图 7 所示) , 设置在彩膜基板表面的第一电极 151与设置彩膜基板上的公共电极 层电连接, 如图 8所示。 当第二隔垫物 14设置于彩膜基板上时, 第一电极 151位于阵列基板上, 第一电极 151与设置在阵列基板上的公共电极层电连 接, 此时公共电极和像素电极设置于不同的基板。
进一步地, 如图 8所示, 位于同一行的第二电极 152均可以与同一条第 二电极线 150相连接, 在本发明实施例中, 第二基板 12为彩膜基板, 这样一 来,每一条第二电极线 150对应一个纵轴坐标,从而可以根据第二电极线 150 上的信号确定触控的纵坐标。 同时,位于同一列的第三电极 16均可以与同一 条第三电极线 160相连接, 在本发明实施例中, 第一基板 11为阵列基板, 如 图 7所示, 这样一来, 每一条第三电极线 160对应一个横轴坐标, 从而可以 根据第三电极线 160上的信号确定触控的横坐标。 采用这样一种结构的液晶 显示面板, 根据第二电极线 150和第三电极线 160的两个信号即可确定触控 位置的横纵坐标, 实现了内嵌式触控功能。
或者, 如图 9所示, 位于同一列的第二电极 152均可以与同一条第二电 极线 150相连接, 在本发明实施例中, 第二基板 12为彩膜基板, 这样一来, 每一条第二电极线 150对应一个横轴坐标, 从而可以根据第二电极线 150上 的信号确定触控的横坐标。 同时,位于同一列的第三电极 16均可以与同一条 第三电极线 160相连接, 在本发明实施例中, 第一基板 11为阵列基板, 如图 10所示, 这样一来, 每一条第三电极线 160对应一个纵轴坐标, 从而可以根 据第三电极线 160上的信号确定触控的纵坐标。 采用这样一种结构的液晶显 示面板, 根据第二电极线 150和第三电极线 160的两个信号即可确定触控位 置的横纵坐标, 实现了内嵌式触控功能。 本发明实施例提供的液晶显示面板, 可以避免在阵列基板上制作用于测 定横纵坐标的两组金属线中的一组, 从而可以有效减小阵列基板上的金属线 区域, 减小了显示器的边框宽度, 提高了显示面板的开口率。
本发明实施例还提供一种显示装置, 其包括如上任一所述的液晶显示面 板。 所述显示装置可以为: 手机、 平板电脑、 电视机、 显示器、 笔记本电脑、 照相机、 摄像机、 数码相框、 导航仪等任何具有显示功能的产品或部件。

5113、 在第二隔垫物的表面和第二基板的与该第二隔垫物对应的表面这 两个表面中的另一个上, 形成第三电极。
5114、 将第一基板和第二基板对盒成型, 使得当不进行触控操作时, 第 三电极不与第一电极和第二电极相接触; 而当进行触控操作时, 第三电极与 第一电极和第二电极相接触。
本发明实施例提供的液晶显示面板制造方法, 通过在一块基板的表面形 成分离的第一电极和第二电极, 在另一块基板的表面形成与第一电极和第二 电极对应的第三电极, 其中, 第一电极和所述第二电极具有不同的电位, 且 在不进行触控操作时, 第三电极不与第一电极和第二电极相接触。 当用户进 行触控操作时, 第三电极将连接并导通第一电极和第二电极, 从而使得第二 电极和第三电极的电位改变, 根据电极的电位变化情况即可对触摸点的坐标 进行锁定。 这样一来, 避免了在阵列基板上制作用于测定横纵坐标的两组金 属线中的一组, 可以有效减小阵列基板上的金属线区域, 从而减小了显示器 的边框宽度, 提高了显示面板的开口率。
举例来说, 第一电极与第二电极之间的间距例如可以在 4-6 μ ιη之间。 这样一种尺寸的电极结构可以采用现有的构图工艺处理得到。
第一基板可以为阵列基板, 第二基板可以为彩膜基板; 或者第一基板可 以为彩膜基板, 第二基板可以为阵列基板。
在本发明实施例中, 均是以第一基板为阵列基板, 第二基板为彩膜基板 为例进行的说明, 可以理解, 本发明实施例所提供的液晶显示面板同样可以 采用第二基板为阵列基板, 本发明对此并不做限制。
当第一基板为阵列基板时,如图 2所示,第一基板 11可以包括以矩阵形 式排列的多个像素单元 21、 与各像素单元 21对应的横向排列的多行栅线 22 以及纵向排列的多列数据线 23。
本发明实施例提供的内嵌式触控面板可以广泛地适用于例如 AD-SDS ( Advanced-Super Dimensional Switching, 筒称为 ADS, 高级超维场开关) 型、 IPS ( In Plane Switch, 横向电场效应)型或 TN ( Twist Nematic, 扭曲向 列)型等类型的液晶显示装置的生产。 无论上述哪种液晶显示装置都包括对 盒成形的彩膜基板和阵列基板。 不同的是, TN型显示装置的公共电极设置 在彩膜基板上, 像素电极设置在阵列基板上; ADS型显示装置和 IPS型显示 装置的公共电极和像素电极均设置在阵列基板上。
在本发明实施例中是以公共电极和像素电极均设置在阵列基板上为例进 行的说明, 其中, 第二隔垫物 14设置于阵列基板上(如图 2所示), 位于第 二隔垫物 14表面的第一电极 151与设置在阵列基板上的公共电极层电连接。 当第二隔垫物 14设置于彩膜基板上时, 位于第二隔垫物 14表面的第一电极 151 可以与设置在阵列基板上的公共电极层电连接, 此时公共电极和像素电 极设置于不同的基板。
进一步地,如图 12所示,所述形成分离的第一电极和第二电极的步骤可 以包括: S 121、 在第一基板和第二基板中形成有公共电极层的基板上形成过孔 , 该过孔的底部延伸到公共电极层。
S122、 在形成有上述结构的基板上对应于第二隔垫物的区域中, 通过构 图工艺形成第一电极、第二电极;该第一电极通过过孔与公共电极层电连接。
例如,可以在形成有上述结构的第一基板上对应于第二隔垫物的区域中, 通过一次构图工艺形成第一电极、 第二电极和第二电极线; 该第一电极可以 通过过孔与公共电极层电连接; 位于同一行的第二电极均与同一条第二电极 线相连接, 根据该第二电极线上的信号确定触控的纵坐标。 这样一来, 每一 条第二电极线对应一个纵轴坐标, 从而可以根据第二电极线上的信号确定触 控的纵坐标。
相应的, 所述形成第三电极的步骤可以包括:
在第二隔垫物的表面和第二基板的与第二隔垫物对应的表面这两个表面 中的另一个上, 形成第三电极和第三电极线; 位于同一列的第三电极均与同 一条第三电极线相连接, 根据该第三电极线上的信号确定触控的横坐标。 这 样一来, 每一条第三电极线对应一个横轴坐标, 从而可以根据第三电极线上 的信号确定触控的横坐标。
或者, 还可以在形成有上述结构的第一基板上对应于第二隔垫物的区域 中, 通过一次构图工艺形成第一电极、 第二电极和第二电极线; 该第一电极 通过所述过孔与公共电极层电连接; 位于同一列的所述第二电极均与同一条 第二电极线相连接, 根据该第二电极线上的信号确定触控的横坐标。 这样一 来, 每一条第二电极线对应一个横轴坐标, 从而可以根据第二电极线上的信 号确定触控的横坐标。
与之相应的, 所述形成第三电极的步骤可以包括:
在第二隔垫物的表面和第二基板的与第二隔垫物对应的表面这两个表面 中的另一个上, 形成第三电极和第三电极线; 位于同一行的所述第三电极均 与同一条第三电极线相连接,根据该第三电极线上的信号确定触控的纵坐标。 这样一来, 每一条第三电极线对应一个纵轴坐标, 从而可以根据第三电极线 上的信号确定触控的纵坐标。
作为替代, 第一电极 151也可以与栅线或者数据线相连, 从而在对栅线 或者数据线提供信号时, 也可以使第一电极 151具有相应的电位, 由于触摸 时间通常大于一帧的扫描时间, 因此, 在触摸所涉及的那一帧时间内, 仍然 可以使第一电极 151具备一定的电位, 从而可以用于确定触控位置的坐标。 这样, 可以无需增加阵列基板上的走线即可实现内嵌式触控功能, 进一步提 高了液晶显示面板的开口率。
本发明实施例提供的液晶显示面板制造方法, 可以避免在阵列基板上制 作用于测定横纵坐标的两组金属线中的一组, 从而可以有效减小阵列基板上 的金属线区域, 减小了显示器的边框宽度, 提高了显示面板的开口率。
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。
