触控显示面板和显示器 技术领域
本发明的实施例涉及一种触控显示面板和显示器。 背景技术
随着平板液晶显示器的迅速发展， 具有触控功能的平板液晶显示器已经 逐渐成为主流的平板显示器。
目前， 触控功能一般通过触控显示面板（Touch Panel )来实现。 现有技 术中的显示面板通常包括分别是彩色滤光片（CF )基板和薄膜晶体管（TFT ) 基板。 为实现触控功能， 在现有的触控显示面板设计中， 主要是在显示面板 的表面额外设置一个具有触控功能的面板即触控面板。 然而， 该额外的触控 面板会增加荧幕的整体厚度并降低显示装置的透光率而影响其亮度表现。
进一步的， 现有的触控显示面板制作过程中， 需要在 CF基板背面的两 层透明的金属极板中间添加绝缘层， 然后在 CF基板上形成一层 BM ( Black Matrix, 黑色矩阵层）。 在制作 CF基板的过程中， 需要在 CF基板上预先制 作一层 BM,这导致之后在制作 RGB色胶层时表面凹凸不平，这需要通过上 覆盖（Over Coating )层来进行平坦化。
因此， 发明人发现上述技术至少存在以下技术问题： 需要在基板外侧单 独制作触控功能面板； 制作工艺复杂。 发明内容

在该触控显示面板中， 例如， 所述第二感应块的形状为正方形或菱形。 本发明的另一方面还提供了一种包括上述触控面板的显示器。
本发明的实施例将感应电极设置到彩色滤光片基板上， 并且在横向和纵 向电极之间釆用黑色矩阵层作为绝缘层， 在不增加制备工艺的同时， 实现了 一种新型的内嵌式触控显示面板， 并且触控面板的感应电极的走线都位于黑 色矩阵的覆盖区域内，使得感应电极对整个触控面板的透过率没有任何影响， 进一步可以实现超薄、 轻便、 具有高透光率和高灵敏度的内嵌式触控显示面 板显示器。 附图说明

在形成的黑色矩阵 12之上设置第二感应电极层，并由所述第二感应电极 层形成纵向设置的多个第二感应电极 11。 即， 第一感应电极 13和第二感应 电极 11彼此垂直。
优选的，所述第二感应电极 11的分布位置与所述黑色矩阵覆盖所述第一 感应电极的覆盖区域相对应， 使第一感应电极 13与第二感应电极 11的走线 都位于黑色矩阵 12的不透光区域内， 使电极对整个面板的透光率没有影响。

本发明实施例中将感应电极转移到彩色滤光片 CF基板上， 并且在横向 和纵向电极之间釆用黑色矩阵层作为绝缘层， 在不增加工艺的同时， 实现了 一种新型的内嵌式电容触控显示面板， 并且触控面板的感应电极的走线都位 于黑色矩阵的覆盖区域内， 使得感应电极对整个触控面板的透过率没有任何 影响， 进一步可以实现超薄、 轻便、 具有高透光率和高灵敏度的内嵌式触控 显示面板显示器。
本发明实施例二将对上述实施例一中的内嵌式触控显示面板的具体实现 过程进行详细的说明， 当然本发明并不引以为限。
实施例一中的 CF基板相对于薄膜晶体管基板 10的一侧设置第一感应电 极 13后正视切面图如图 2所示。例如，第一感应电极层可以釆用透明电极材 料例如铟锡氧化物 （ITO )形成的导电层， 也可以是釆用不透明电极材料例 如金属形成的导电层， 并最终形成多个横向设置的第一感应电极 13。 优选的， 第一感应电极 13包括至少两个隔开的、 配对的第一感应块， 该 第一感应块的形状可以为菱形或正方形等， 本发明不限于此。
例如， 第一感应块的数量以及两两之间的间距可以根据实际需要来调整 设置， 并通过金属线与感应器相连。
形成黑色矩阵 12后 CF基板的正视切面结构示意图如图 3所示。
例如， 该黑色矩阵 12不透光的覆盖区域需要将第一感应电极 13的分布 位置和所述第二感应电极 11的分布位置完全覆盖。 该黑色矩阵 12的材料选 用绝缘的树脂材料， 作为横向和纵向感应电极的绝缘层。
优选的，该黑色矩阵 12的位置可根据薄膜晶体管基板对彩色滤光片中黑 色矩阵的位置要求来设定。

第二感应块的形状可以为正方形、 菱形等形状， 本发明不限于此。 顺序形成着色层后的 CF基板正视切面结构示意图如图 5所示。
优选的， 在上述形成着色层后， 还可以再在整个基板的整面上形成一层 透明导电层（例如 ITO ) ， 将其用作薄膜液晶显示器的公共电极的同时， 也 可以将其作为上述内嵌式触控显示面板的屏蔽层。
本发明实施例三还提供了一种应用实施例一与实施例二形成的内嵌式触 控显示面板制作的触控显示器， 该触控显示器包括上述实施例中提供的内嵌 式触控显示面板。 该显示器还包括用于实现触控的控制器， 该控制器例如可 以独立于触控显示面板形成， 也可以与触控显示面板一体形成。 该触控显示 器例如可以用于电视、 电脑、 手机等。
该触控显示器的工作原理示意图如图 6所示。 第一感应电极层与第二感 应电极之间的黑色矩阵层作为第一感应电极与第二感应电极的绝缘层， 形成 电容。 当有触摸发生时， 根据其中某点的电容变化引起横纵不同行的电流或 者脉冲信号发生变化， 控制器通过与之连接的横向第一感应电极和纵向第二 感应电极分别进行检测， 确定出触摸点发生的横纵坐标， 实现寻址。
本发明实施例提供的触控显示器， 在不增加工艺的同时， 并且是在其他 设计参数和显示效果不变的情况下， 提高了显示器的光学特性和电学特性， 是一种高性能的、 成本降低的、 超薄的触控平板显示器。
