为了使本发明的目的， 技术方案和优点更加清楚， 下面结合附图来进一步 #丈详细说明。 实施例一
如图 3和图 4所示， 本实施例中的内嵌式触摸屏彩膜基板 200包括： 一基 板 201 ; 形成于所述基板 201上具有多个开口 202的黑矩阵 203; 形成于所述黑 矩阵 203上的多个感应电极 204和多个驱动电极 205 ,所述感应电极 204和驱动 电极 205之间相互独立。 其中， 所述感应电极 204和驱动电极 205之间的黑矩 阵 203断开， 所述黑矩阵断开部分由不透光材料 206遮挡。 如图 3所示， 所述内嵌式触摸屏彩膜基板 200还包括形成于所述感应电极 204和驱动电极 205上的彩膜层 207 , 所述彩膜层 207包括按照预定格式排列在 所述黑矩阵的开口 202内的三种彩膜： 红色彩膜（R )、 绿色彩膜（G )和蓝色彩 膜（B )。 相邻的两个开口 202内的两种彩膜还分别延伸以覆盖所述两个开口之 间的黑矩阵断开部分。 任意两种彩膜组合后， 其组合后的彩膜的透光率会大幅 下降， 在本实施例中就是利用这一特性， 将所述两种彩膜的延伸部分作为所述 不透光材料 206。
通常， 所述感应电极 204和驱动电极 205所使用的材料有两种； 不透明的 金属材料和透明的金属材料。 本实施例中， 感应电极 204和驱动电极 205釆用 的是不透明的金属材料。 对于不透明的感应电极 204和驱动电极 205来说， 所 述感应电极 204和驱动电极 205只能形成于所述黑矩阵 203的非开口区域， 否 则会出现感应电极 204和驱动电极 205遮挡显示光线的情况。 当然， 在另一实 施例中， 感应电极 204和驱动电极 205也可以釆用透明金属材料， 对于透明的 感应电极 204和驱动电极 205来说， 所述感应电极 204和驱动电极 205可以形 成于所述黑矩阵 203的任何部位， 对于彩膜基板设计来说更方便。
如图 5所示， 所述感应电极 204包括第一部分感应电极 2041和第二部分感 应电极 2042 , 所述第一部分感应电极 2041和第二部分感应电极 2042分别位于 所述内嵌式触摸屏彩膜基板 200两个独立区域内。 同样， 所述驱动电极 205包 括第一部分驱动电极 2051和第二部分驱动电极 2052 , 所述第一部分驱动电极 2051和第二部分驱动电极 2052分别位于所述内嵌式触摸屏彩膜基板 200两个独 立区域内。 第一部分感应电极 2041和第二部分感应电极 2042的排列方向与第 一部分驱动电极 2051和第二部分驱动电极 2052的排列方向纵横交错。 所述第 一部分驱动电极 2051和第二部分驱动电极 2052通过同层连线连接在一起。
如图 5所示， 为了进一步降低所述感应电极 204的电阻， 在所述第一部分 感应电极 2041和第二部分感应电极 2042的对应区域上设置第一透明导电层 209。 同样的， 为了进一步降低所述驱动电极 205的电阻， 在所述第一部分驱动 电极 2051和第二部分驱动电极 2052的对应区域上设置第二透明导电层 210。当 然， 为了简化生产流程节约成本， 在其他实施例中， 也可以不设置第一透明导 电层 209和第二透明导电层 210。 结合图 3和图 5 , 为了平坦化所述彩膜基板，设置覆盖所述第一透明导电层 209、 第二透明导电层 210以及其他区域的黑矩阵 203的平坦层 211 , 在对应于 部分第一部分感应电极 2041和部分第二部分感应电极 2042上的平坦层 211上 形成有至少两个通孔 212, 在所述平坦层 211上和通孔 212内形成有金属搭桥 213 , 所述金属搭桥 213通过通孔 212将所述第一部分感应电极 2041和第二部 分感应电极 2042连接在一起。
如图 6所示， 相应的， 本实施例还提供一种内嵌式触摸屏 20包括： 上述内 嵌式触摸屏彩膜基板 200、阵列基板 300以及设置于所述彩膜基板 200和阵列基 板 300之间的液晶层 400。
本实施例中， 将黑矩阵的断开部分和不透光材料直接都集成在彩膜基板上， 因此， 上述两者之间的相关联的设计都涉及彩膜基板的配套设计， 不会影响阵 列基板的相关设计， 因此其设计的具有更大空间的灵活性。 另外， 彩膜基板的 制造工艺也不会干涉到阵列基板的制造工艺。 实施例二
本实施例与实施例一的主要区别在于， 本实施例中的不透光材料是设置于 阵列基板上的。
如图 7所示， 本实施例中的内嵌式触摸屏彩膜基板 500包括： 一基板 501 ; 形成于所述基板 501上具有多个开口 502的黑矩阵 503 ; 形成于所述黑矩阵 503 上的多个感应电极 504和多个驱动电极 505 ,所述感应电极 504和驱动电极之间 相互独立。 其中， 所述感应电极 504和驱动电极 505之间的黑矩阵 203断开。
如图 8所示， 相应的， 本实施例还提供一种内嵌式触摸屏 30包括： 上述内 嵌式触摸屏彩膜基板 500、阵列基板 600以及设置于所述彩膜基板 500和阵列基 板 600之间的液晶层 700。
如图 9所示，所述阵列基板 600上形成有多条数据线 601和多条栅极线 602 , 所述数据线 601和栅极线 602所限定的区域与所述黑矩阵的开口 502相对应。 与所述黑矩阵的断开部分相对应的所述栅极 602线的宽度至少覆盖所述黑矩阵 的断开部分。 与所述黑矩阵的断开部分相对应的所述数据线 601的宽度至少覆 盖所述黑矩阵的断开部分。 在本实施例中， 由与所述黑矩阵的断开部分相对应所述数据线 601或者栅 极线 602作为不透光材料。 为了保证对黑矩阵的断开部分的挡光效果， 所述数 据线 601覆盖所述黑矩阵断开部分以及所述栅极线 602覆盖所述黑矩阵断开部 分必须为不透明材料。 至于， 与所述黑矩阵断开部分以外的黑矩阵 203相对应 的数据线 601和栅极线 602 , 对其材料可以不做限定， 可以釆用不透明的材料， 也可以釆用透明材料， 如氧化铟锡等。 当然， 为了简化生产制造流程， 数据线 601和栅极线 602可以整体都釆用不透光的材料。 具体的， 所述数据线 601和栅 极线 602可以釆用不透明的金属， 例如铬、 铝、 铜等金属的一种或者几种的合 金。
在本实施中， 釆用不透明的数据线和栅极线作为不透光材料， 因为其釆用 完全不透光的金属材料， 因此可以将黑矩阵断开部分的漏光完全遮挡。 而在实 施例一中是釆用相邻两种彩膜的重复遮挡作为不透光材料的， 其并不能将所有 的光线都遮挡， 而只能遮挡一部分光线。 例如， 相邻的彩膜是红色彩膜和绿色 彩膜时， 由红色彩膜和绿色彩膜重复遮挡以后， 黄色光线还是可以穿透的。 因 此， 本实施例一中的不透光材料的遮光效果优于实施例一中的不透光材料的遮 光效果。
综上所述， 本发明所提供一种内嵌式触摸屏彩膜基板， 将感应电极和驱动 电极之间的黑矩阵断开， 从而杜绝了黑矩阵将感应电极和驱动电极导通的情况。 同时， 为了避免黑矩阵断开部分引起漏光， 将在黑矩阵断开部分利用一不透光 材料遮挡。 以此避免了感应电极和驱动电极的导通风险， 同时也不会引起相应 漏光不良。
需要说明的是， 本说明书中各个实施例釆用递进的方式描述， 每个实施例 重点说明的都是与其他实施例的不同之处， 各个实施例之间相同相似部分互相 参见即可。
需要说明的是， 本发明实施例中的方案不仅可用于 TN显示模式的 LCD, 还可用于 FFS显示模式的 LCD其他显示模式的 LCD。
显然， 本领域的技术人员可以对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， 则本发明也意图包括这些改动和变型在内。
