本申请要求于 2012 年 9 月 04 日提交中国专利局、 申请号为 201210324389.6、 发明名称为 "带有触摸功能的 CF基板及触摸面板"的中国 专利申请的优先权, 其全部内容通过引用结合在本申请中。
技术领域
本发明涉及触摸显示领域, 尤其涉及一种带有触摸功能的 CF基板及触摸 面板。
背景技术
触摸屏作为一种输入媒介, 是目前最筒单、 方便、 自然的一种人机交互方 式。 液晶 ( Liquid Crystal ) , 由于其良好的电可控性, 越来越多地使用在显示 面板中。 因此, 通常触摸屏集成于液晶显示面板中形成各种电子产品, 例如手 机、 笔记本电脑、 ΜΡ3/ΜΡ4等。
触摸面板, 根据液晶的显示方式, 目前广泛应用的有扭曲 (Twisted Nematic, TN )显示方式、 平面转换( In-Plane Switching, IPS )方式与边缘场 开关 (Fringe Field Swithing, FFS ) 方式。 不论何种显示方式, 触摸面板一般 包括彩膜(Colour Film, CF )基板, TFT基板, 以及两者之间所夹的液晶。 触 摸结构一般形成在 CF基板, 为了实现触摸面板的功能, 至少需对 CF基板输入 触控信号、 采集输出的触控信号的变化及对 TFT基板施加使液晶旋转或扭曲的 信号。 现有技术中, 上述信号的输入、输出与施加一般通过各自的柔性电路板 ( FPC )分别与 CF基板、 TFT基板连接加以实现。 然而, 上述两块柔性电路板 会造成电路引线复杂, 不利于集成化。 为了避免上述问题, 现有技术也有一些 方案提出, 例如将 CF基板与 TFT基板电连接, 由 TFT基板这一个基板与其它电 路板之间形成电导通以使得各种信号得以输入输出。
然而, 本发明人在研究上述触摸显示面板过程中, 发现为了实现 CF基 板与 TFT基板电连接, 触摸面板制作时, 在 CF基板与 TFT基板对位后, 由 于某些制程需要(例如显示区域制程需要,需在 CF基板表面覆盖保护膜等), 造成 CF基板与 TFT基板两者对应的引脚(例如位于非显示区域)之间具有 较大的间隙, 这样, 为实现 CF基板与 TFT基板电连接, 在两者的各自引脚 之间的导电胶需要涂布较厚。 这样的触摸面板在制作时, 该涂布较厚的导电 胶容易出现断胶以及胶宽粗细不一的现象, 在使用时, 会有外界水汽等杂质 进入, 影响产品良率以及产品的导电性能。

可选地, 所述导电胶为框胶。
可选地, 所述导电胶为包含单一直径的导电球的密封胶。 与现有技术相比, 本发明具有以下优点:
1 ) CF基板的第一引脚适于与 TFT基板上对应的第二引脚电连接, 本发 明采用将 CF基板的第一引脚设置为包括第一端与第二端, 其中, 第一端与 触控层电连接,第二端相对第一端远离 CF基板的衬底,即抬高了适于与 TFT 基板的第二引脚进行电连接的第一引脚的部分区域(第二端) 的高度, 利用 第一引脚整体等电势的性质, 实现了将触控层的信号引入 TFT基板, 且减小 了 CF基板与 TFT基板对应引脚之间的间距, 即需涂布的导电胶的厚度, 使 得该导电胶不易出现断胶或胶宽粗细不一现象, 提高了导电性能。 2 )可选方案中, 该触控层包括第一导电层、 第二导电层以及两者之间的 第一透明绝缘层, 其中, 第一导电层形成多个驱动电极及多个感应电极, 并 且多个驱动电极之间由第一连接线连接在一起形成驱动线, 第二导电层形成 多个第二连接线, 该第二连接线通过设置在第一透明绝缘层内的过孔将多个 感应电极连接在一起形成感应线。 上述触控层的设置方式中, 驱动电极和感 应电极交叠形成互电容, 触摸该面板时, 会使得该互电容发生变化, 该触摸 点即可被检测。
3 )可选方案中, 第一引脚的第一端与驱动线和 /或感应线连接, 为第一 引脚的第一端提供了明确的连接对象。
4 )可选方案中, 该驱动电极、 感应电极、 第一连接线、 第二连接线、 第 一引脚的第一端、 第二端及连接该第一端与第二端的导电连接层的制作过程 中, 第一导电层同时制作出多个驱动电极、 多个感应电极、 第一连接线、 第 一引脚的第一端, 接着在上述结构上设置第一透明绝缘层, 并在预定位置形 成过孔, 然后在第一透明绝缘层及过孔内设置第二导电层, 刻蚀该第二导电 层同时形成了第二连接线, 第一引脚的第二端, 连接第一引脚的第一端与第 二端的导电连接层, 其中, 该导电连接层、 第二连接线的部分形成在过孔内。 相对于分别制作触控层的各结构与第一引脚的各结构的方案, 上述制作方法 将两者结构同时制作, 节省了工艺步骤, 提高了效率。
5 )可选方案中, 制作完触控层后, CF基板预定有显示区域与围绕显示 区域的框胶涂布区域, 第一引脚的第二端位于框胶涂布区域, 接着进行 CF 基板的制作: 在位于显示区域的触控层上形成彩色滤光层, 接着在显示区域 及框胶涂布区域形成第二透明绝缘层, 去除框胶涂布区域的第二透明绝缘层 形成沟槽, 该沟槽至少暴露第一引脚的第二端, 此时, 该第一引脚的第一端 可以位于框胶涂布区域, 也可以不位于框胶涂布区域, 该第一端也可以被沟 槽暴露, 也可以不暴露。 上述方案基于的问题是: 由于 CF基板与 TFT基板 两者除了相应的引脚之外, 还有其它位置, 例如框胶涂布区域需要通过框胶 粘合, 在这些位置, CF基板与 TFT基板之间的间隙与两基板之间相应引脚 位置的间隙不一致, 导致导电胶与框胶的涂布需分步进行, 增加了涂布工艺 的复杂性, 会影响生产效率。 针对上述问题, 可以理解, 本可选方案的好处 在于: 导电胶若选择封框导电胶, 则不但实现了 CF基板与 TFT基板的电连 接, 而且实现了两基板之间的封框, 相对先进行两基板之间对应引脚的电连 接(导电胶涂布), 然后进行封框的方案 (框胶涂布), 即上述两个步骤分别 进行的工艺,本方案通过一次涂布导电胶,不但实现了两基板之间的电连接, 而且实现了封框, 减少了工艺步骤, 提高了效率。
6 )可选方案中, 由于连接第一引脚的第一端与第二端的导电连接层是形 成在第一透明绝缘层的过孔内, 该第一透明绝缘层一般为有机膜, 因而在其 内形成的过孔一般为底部小, 顶部开口大的过孔, 该底部小, 顶部开口大的 过孔的侧壁为緩坡状, 导电连接层覆盖所述緩坡状侧壁, 即可完成连接第一 引脚的第一端与第二端。
7 )可选方案中, 为减小第一引脚的第一端与第二端之间的距离(减小导 电连接层的尺寸), 也同时为了减小第一透明绝缘层的厚度, 针对 5 )提供的 方案, 该第一引脚的第一端优选位于框胶涂布区域。 附图说明 图 1至图 7是本发明实施例一的制作流程对应的 CF基板结构示意图; 图 8至图 9是本发明实施例一的触摸面板的结构示意图; 图 10至图 12是本发明实施例二的制作流程对应的 CF基板结构示意图; 图 13至图 14是本发明实施例二的触摸面板的结构示意图; 图 15是本发明实施例三的制作流程对应的 CF基板结构示意图; 图 16是本发明实施例三的触摸面板的结构示意图; 图 17是本发明实施例五的制作流程对应的 CF基板结构示意图; 图 18是本发明实施例六的制作流程对应的 CF基板结构示意图; 图 19是本发明实施例六的触摸面板的结构示意图。
具体实施方式 针对背景技术所述的现有技术的缺陷: 在 CF基板与 TFT基板对位后, 由于显示区域的制程需要, 造成 CF基板与 TFT基板两者的非显示区域之间 具有较大的间隙, 这样, 为实现将 CF基板的电信号引入 TFT基板, 在两者 的各自引脚之间的导电胶需要涂布较厚, 该较厚的导电胶易断胶或出现胶宽 粗细不一等问题, 造成水汽等进入影响信号的传输; 本发明采用将 CF基板 上的第一引脚设置为包括第一端与第二端, 其中第一端与触控层电连接, 第 二端相对第一端远离衬底, 即抬高了适于与 TFT基板进行电连接的第一引脚 的部分区域的高度, 从而减小了 CF基板与 TFT基板之间需涂布的导电胶的 厚度, 使得该导电胶不易出现断胶或胶宽粗细不一现象, 提高了导电性能。 为使本发明的上述目的、 特征和优点能够更加明显易懂, 下面结合附图 对本发明的具体实施方式做详细的说明。
为方便理解本发明的技术方案,以下列出本发明中出现的所有附图标记。 衬底 10 显示区域 101 框胶涂布区域 102 驱动电极 111 感应电极 112 第一连接线 113 第一透明绝缘层 12 过孔 121 第二连接线 131 第一引脚 2 导电连接层 132 第一引脚的第二端 133 第二透明绝缘层 14
Figure imgf000010_0001
沟槽 141, 框胶 15 第一引脚的第一端 150 抬高 CF基板的第一引脚的部分区域的高度, 其实现方式具有多种。 此 外,正如前面所述,上述方案实现连接 CF基板与 TFT基板各自引脚的同时, 还可以对 CF基板与 TFT基板进行封框, 以下实施例一至六均以同时实现上 述两功能为例进行详细说明。 但可以理解的是, 以下提供的方案不限于必须 同时实现封框的功能。 实施例一 为清楚理解本发明的技术方案, 首先介绍本实施例一提供的 CF基板的 制作方法。
首先, 执行步骤 S11 , 提供衬底 10。
如图 1所示,该衬底 10包括显示区域 101及围绕所述显示区域 101设置 的框胶涂布区域 102。 该衬底 10为透明材质, 例如玻璃等。
接着, 执行步骤 S12, 参照图 2所示, 在衬底 10上沉积第一导电层, 并 刻蚀形成多个驱动电极 111和多个感应电极 112, 以及多个第一连接线 113 , 多个第一连接线 113将多个驱动电极 111连接在一起形成驱动线, 同时还形 成多个第一引脚 2的第一端 150, 所述该第一引脚 2的第一端 150位于框胶 涂布区域 102内,并且所述多个第一引脚 2的第一端 150分别和驱动电极 111 或者感应电极 112连接。
为方便显示, 图 2所示以四行感应线、 三列驱动线为例制作 CF基板的 触控层, 每个驱动电极 111和感应电极 112交叠形成互电容。 制作时, 该第 一导电层的材质为金属或 ITO等。 本步骤中的刻蚀工艺为现有工艺, 具体参 数参照现有工艺完成, 在此不再赘述。
接着,执行步骤 S13 ,参照图 3与沿图 3中 A-A直线的剖视图图 4所示, 在上述包含多个驱动电极 111、 多个感应电极 112、 多个第一连接线 113以及 多个第一引脚 2的第一端 150的衬底 10上形成第一透明绝缘层 12, 并在第 一透明绝缘层 12的预定位置形成过孔。
本步骤中的预定位置形成过孔主要包括两个: 1 )位于感应电极 112上的过孔, 用于露出每个感应电极 112的部分。 在 后续步骤中形成导电层时(步骤 S14 中淀积第二导电层时形成), 所述过孔 的内部会沉积导电层的物质, 同时通过所述导电层形成的第二连接线, 将多 个感应电极 112连接在一起形成感应线。 在形成触控层时, 通过过孔形成跨 桥部为常规技术, 因而未图示对应感应电极 112区域的过孔。
2 )位于框胶涂布区域 102内的过孔 121 ,如图 3与图 4所示,该过孔 121 的底部完全暴露第一引脚 2的第一端 150。
该透明绝缘层 12的材质可以为二氧化硅等,考虑到 CF基板后续触控层 的其它结构制作, 该层材质优选流动性较好的有机膜。
在第一绝缘层 12选择有机膜时,在其内形成过孔 121的形状一般为底部 小, 开口大的梯形结构; 在第一绝缘层 12选择二氧化硅时, 在其内形成过孔 121 的形状可以为具有竖直侧壁的通孔, 也可以处理形成底部小, 开口大的 梯形结构。
然后,执行步骤 S14,参照图 5与沿图 5中 B-B直线的剖视图图 6所示, 在第一透明绝缘层 12及其上的过孔内淀积第二导电层,刻蚀第二导电层形成 多个第二连接线 131、第一引脚 2的第二端 133、及连接第一引脚 2的第一端 150与第二端 133的导电连接层 132。
可以理解的是, 暴露第一引脚 2的第一端 150的过孔 121较小, 在淀积 第二导电层时, 该过孔被填满具有导电性。 在感应电极 112上的过孔也被填 满, 该过孔 121的大小及第二导电层的淀积厚度, 只要使得第二连接线 131 两边的感应电极 112电连接即可。 暴露第一引脚 2的第一端 150的过孔 121 在淀积第二导电层时,若过孔 121的侧壁为緩坡状,则在緩坡状及该过孔 121 外位于框胶涂布区域 102的第一绝缘层 12上也都有第二导电层, 经刻蚀后, 位于框胶涂布区域 102的第二导电层形成了第一引脚 2的第二端 133 , 则緩 坡状的第一绝缘层 12上的第二导电层则形成了连接第一引脚 2的第一端 150 与第二端 133的导电连接层 132。
本步骤完成后, 该多个第二连接线 131 通过设置在第一透明绝缘层 12 内的过孔 121将所述多个感应电极 112连接在一起形成感应线, 该第一引脚 2的第二端 133及连接第一端 150与第二端 133的导电连接层 132也得以形 成。 制作时, 该第二导电层的材质为金属或 ITO等。 本步骤中的刻蚀工艺为 现有工艺, 具体参数参照现有工艺完成, 在此不再赘述。 为提高增强第一引 脚 2的第一端 150的导电性,步骤 S12中淀积的第一导电层的材质为金属时, 本步骤中淀积的第二导电层的材质为金属或 ITO; 步骤 S12中淀积的第一导 电层的材质为 ITO时, 本步骤中淀积的第二导电层的材质优选金属。
经过上述步骤, 包括驱动线、 感应线的触控层, 以及第一引脚 2的第二 端 133已形成完毕。
为完成 CF基板的制作, 接着, 执行步骤 S15 , 参照图 7所示, 在显示 区域 101的触控层的上方形成彩色滤光层(未图示),及在显示区域 101的彩 色滤光层及框胶涂布区域 102上形成第二透明绝缘层 14,并在框胶涂布区域 102的第二透明绝缘层 14内形成围绕显示区域 101—圏首尾相接的沟槽 141 , 该沟槽 141暴露第一引脚 2的第二端 133。 其它实施例中,也可以在框胶涂布区域 102的第二透明绝缘层 14内形成 暴露第一引脚 2的第二端 133的过孔, 围绕显示区域 101的其余框胶涂布区 域 102的第二透明绝缘层 14内形成沟槽 141 , 换言之, 该沟槽 141也可以不 为首尾相接。
第二透明绝缘层 14的材质与第一透明绝缘层 12的材质类似, 可以为二 氧化硅,考虑到 CF基板表面需夹持液晶,该层优选可以平坦 CF基板表面的 材质, 例如填充性较好的有机膜, 此外, 该有机膜还能隔绝水气等污染, 提 高所述 CF基板的可靠性。
至此, CF基板已制作完毕。 可以理解的是, 步骤 S12-S14中驱动线与感 应线的形成顺序不限, 即可先形成感应线, 再形成驱动线。 其它实施例中, 也可以形成其它现有的触控层结构,只要实现第一引脚的第一端与驱动线和 / 或感应线电连接即可。
基于上述的 CF基板, 本实施例还提供了一种触摸面板, 该触摸面板除 了包括上述的 CF基板, 还包括: TFT基板(未图示), 该 TFT基板上设置 有对应第一引脚 2的第二引脚, 该第二引脚连接至触控信号输入端; TFT基 板上第二引脚与所述 CF基板的第一引脚 2的第二端 133通过导电胶连接。
本实施例中, 正如前面所述, CF基板与 TFT基板实现连接各自引脚的 同时, 如图 8所示, 还实现对 CF基板与 TFT基板进行封框, 因而, 该导电 胶也为框胶 15。 具体地, 针对沟槽 141的设置方式, 不论其为: 1 ) 围绕显 示区域 101—圏首尾相接的情况, 还是 2 )设置有第一引脚 2的框胶涂布区 域 102具有暴露第一引脚 2的第二端 133的过孔, 其余框胶涂布区域 102为 沟槽 141的情况, 如沿图 8中的 C-C直线的剖视图图 9所示, 该导电胶可以 为包含单一直径的导电球的密封胶, 该密封胶除了导电球外, 其余胶体部分 不导电, 通过调整导电球的密度, 实现只在上下方向, 即第一引脚与第二引 脚的电导通, 而在不同第一引脚之间无电导通; 另外, 该密封胶除了包含单 一直径的导电球, 例如金球外, 还可以包含支撑球, 例如硅球, 该硅球具有 一定弹性, 其直径优选大于金球直径 5%~30%。 此外, 该导电胶也可以采用 能实现单一导电方向的导电胶, 只实现上下方向 (第一引脚到第二引脚方向 及相反方向)导通。
可以理解的是, 若 CF基板与 TFT基板只需实现连接各自引脚的功能, 则位于 CF基板的第一引脚 2不限于位于框胶涂布区域 102。此外,在非框胶 涂布区域,用于导电胶设置的位置, 即位于第二透明绝缘层 14内暴露第一引 脚 2第二端 133的沟槽也不限于为沟槽, 过孔也可。 对于在非框胶涂布区域 暴露第一引脚 2第二端 133的过孔, 其内涂布普通导电胶即可。
可以看出,本实施例中,将 CF基板的第一引脚 2设置为包括第一端 150 与第二端 133 , 其中, 第一端 150与触控层电连接, 第二端 133相对第一端 150远离 CF基板的衬底, 即抬高了适于与 TFT基板的第二引脚进行电连接 的第一引脚的部分区域(第二端 133 ) 的高度, 利用第一引脚 2整体等电势 的性质, 实现了将触控层的信号引入 TFT基板, 且减小了 CF基板的第一引 脚 2与 TFT基板的第二引脚之间的间距, 即需涂布的导电胶的厚度, 使得该 导电胶不易出现断胶或胶宽粗细不一现象, 提高了导电性能。 此外,导电胶选择能实现导电功能的框胶,则不但实现了 CF基板与 TFT 基板的电连接, 而且实现了两基板之间的封框, 换言之, 针对一个 CF基板, 本方案通过一次涂布导电胶, 不但实现了两基板之间的电连接, 而且实现了 封框, 减少了工艺步骤, 提高了效率。
实施例二 本实施例二提供的 CF基板及包含该 CF基板的触摸面板的结构及其制作 方法为:
首先, 执行步骤 S11 , 提供衬底, 该衬底包括显示区域 101及围绕所述 显示区域 101设置的框胶涂布区域 102。 执行步骤 S12, 在衬底的显示区域 101沉积第一导电层, 并刻蚀形成多 个驱动电极 111和多个感应电极 112, 以及多个第一连接线 113 , 多个第一连 接线 113将多个驱动电极 111连接在一起形成驱动线, 同时还形成多个第一 引脚 2的第一端 150, 并且所述多个第一引脚 2的第一端 150分别和驱动电 极 111或者感应电极 112连接。 本实施例二中, 如图 10所示, 步骤 S12中形 成的第一引脚 2的第一端 150位于框胶涂布区域 102内。 接着执行与实施例一相同的步骤 S13、 S14、 S15。 第一引脚 2的第二端 133及连接第一端 150 (驱动电极 111和 /或感应电极 112 )与第二端 133的导 电连接层 132利用第二导电层在步骤 S14中形成, 步骤 S15完成后, 在框胶 涂布区域 102的第二透明绝缘层 14内形成围绕显示区域 101—圏首尾相接的 沟槽 141 , 如图 11及沿图 11中 D-D直线的剖视图图 12所示。
基于上述的 CF基板, 本实施例也提供了一种触摸面板, 该触摸面板除 了包括上述的 CF基板, 还包括: TFT基板(未图示), 该 TFT基板上设置 有对应第一引脚的第二引脚, 该第二引脚连接至触控信号输入端; TFT基 板上第二引脚与所述 CF基板的第一引脚的第二端通过导电胶连接。 本实施 例中, 正如前面所述, CF基板与 TFT基板实现连接各自引脚的同时, 如图 13所示,还实现对 CF基板与 TFT基板进行封框,因而,该导电胶为框胶 15。 具体地, 如沿图 13中的 E-E直线的剖视图图 14所示, 该导电胶可以为包含 单一直径的导电球(例如金球和硅球) 的密封胶。 即, 本发明提供的触控面 板, 将 CF基板的触控层和 TFT基板的引脚导通的步骤和 CF基板和 TFT基 板的密封步骤合并为一个工艺步骤, 筒化了制造工艺, 降低成本。
可以理解的是, 若 CF基板与 TFT基板只需实现连接各自引脚的功能, 则位于 CF基板的第一引脚不限于位于框胶涂布区域 102,此外,用于导电胶 设置的位置,即位于第二透明绝缘层 14内暴露第一引脚 2第二端 133的沟槽 也不限于为沟槽, 过孔也可。
实施例三
不同于上述两个方案, 如图 15所示, 本实施例三步骤 S12中第一引脚 的第一端 150部分位于显示区域 101内, 部分位于框胶涂布区域 102内。 相 应地, 形成的触摸面板(TFT基板未图示) 的截面结构如图 16所示。 除此 之外,本实施例三提供的 CF基板及包含该 CF基板的触摸面板的结构及其制 作方法都与实施例一、 二相同。
实施例四 本实施例四提供的 CF基板及包含该 CF基板的触摸面板的结构及其制作 方法大致与上述各实施例相同。区别在于:步骤 S 12中为了形成驱动电极 111、 感应电极 112、 第一连接线 113以及第一引脚的第一端 150而淀积的第一导 电层为金属及其上的 ΙΤΟ。 ΙΤΟ由于较为致密, 因而设置于金属上, 可用于 隔绝水气等其它污染物。 此时, 考虑到步骤 S14中位于通孔 121内的驱动电 极 111和 /或感应电极 112上也形成有第二导电层, 为提高增强第一引脚 2的 第一端 150的导电性, 步骤 S14中淀积的第二导电层的材质优选金属。
实施例五 本实施例五提供的 CF基板及包含该 CF基板的触摸面板的结构及其制作 方法大致与上述各实施例相同。 区别在于: 步骤 S13 中, 如图 17所示, 在 第一透明绝缘层 12 内形成的用于暴露第一引脚 2的第一端 150的过孔 121 的底部暴露驱动电极 111和 /或感应电极 112的部分, 并非全部暴露。
实施例六
本实施例五提供的 CF基板及包含该 CF基板的触摸面板的结构及其制作 方法大致与上述各实施例相同。 区别在于: 步骤 S15 中, 参照图 18所示, 在框胶涂布区域 102的第二透明绝缘层 14内形成围绕显示区域 101—圏首尾 相接的沟槽 14Γ , 该沟槽 141,不只暴露第一引脚 2的第二端 133 , 还暴露第 一引脚 2的第一端 150的部分。相应地, 形成的触摸面板(TFT基板未图示) 的截面结构如图 19所示, 由于第一引脚 2的三个部分, 即第一端 150、 导电 连接层 132、 第二端 133形成电连接, 第一引脚 2等电势, 因而, 导电胶中 单一直径的导电球(例如金球和硅球)与第一引脚 2的部分接触即可。
其它实施例中,在框胶涂布区域 102的第二透明绝缘层 14内形成围绕显 示区域 101—圏首尾相接的沟槽也可以暴露导电连接层 132的部分或全部暴 露导电连接层 132与第一引脚的第一端 150都可。
本说明书中的各个实施例均采用递进的方式描述, 各个实施例之间相同 相似的部分互相参见即可, 每个实施例重点说明的都是与其它实施例的不同 之处。
本发明虽然已以较佳实施例公开如上, 但其并不是用来限定本发明, 任 何本领域技术人员在不脱离本发明的精神和范围内, 都可以利用上述揭示的 方法和技术内容对本发明技术方案做出可能的变动和修改, 因此, 凡是未脱 筒单修改、 等同变化及修饰, 均属于本发明技术方案的保护范围。
