Description

液晶显示面板和显示装置 技术领域
本发明的实施例涉及一种液晶显示面板和显示装置。 背景技术
薄膜晶体管液晶显示器 ( Thin Film Transistor Liquid Crystal Display, TFT-LCD ) 因其具有体积小、 重量轻、 功耗低等优点， 在监视器、 电视、 笔 记本等各领域中得到了广泛的应用， 成为当前主流的显示器。
TFT-LCD的关键技术是液晶显示模式， 液晶显示模式决定了 TFT-LCD 的显示质量、 制造成本和制造工艺。 此外， 为了使液晶显示器能够用于大屏 幕显示， 还需要改善其视角特性和提高响应速度等。 LCD的视角窄是指在偏 离液晶盒法线方向观察时， 对比度明显下降， 并且在偏离角度进一步增大时 还会发生灰阶反转现象， 严重影响 LCD 的显示质量。 目前， 已经提出了很 多解决 LCD 的视角问题的方法， 例如， 光学补偿弯曲排列模式（OCB ) 、 面内开关模式（ IPS )、 边缘场开关模式（ FFS )和多畴竖直排列模式（ MVA ) 等。
然而， 在上述各种模式的 LCD 中， 均存在能耗大、 色调分辨率低、 色 彩的鲜明度低等问题。 发明内容
本发明的一个实施例提供了一种液晶显示面板， 其包括： 对盒成型的彩 膜基板和阵列基板， 在所述彩膜基板和所述阵列基板上分别设置有取向膜； 以及液晶， 填充在所述彩膜基板和所述阵列基板之间， 其中， 所述液晶在所 述彩膜基板处的取向方向为垂直取向， 并且所述液晶在所述阵列基板处的取 向方向为水平取向； 或者， 其中， 所述液晶在所述彩膜基板处的取向方向为 水平取向， 并且所述液晶在所述阵列基板处的取向方向为垂直取向。
本发明的另一个实施例提供了一种显示装置，其包括上述液晶显示面板。 附图说明
为了更清楚地说明本发明实施例的技术方案， 下面将对实施例的附图作 简单地介绍，显而易见地，下面描述中的附图仅仅涉及本发明的一些实施例， 而非对本发明的限制。
图 1为本发明实施例提供的一种液晶显示面板的结构的示意图； 图 2为本发明实施例提供的另一种液晶显示面板的结构的示意图； 图 3为本发明实施例提供的液晶显示面板的阵列基板的结构的俯视图； 图 4为具有图 1所示的结构的液晶显示面板在通电时液晶的状态图； 图 5为具有图 2所示的结构的液晶显示面板在通电时液晶的状态图； 图 6为本发明另一实施例提供的一种液晶显示面板的结构的示意图； 图 7为本发明另一实施例提供的另一种液晶显示面板的结构的示意图； 图 8为具有图 6所示的结构的液晶显示面板在通电时液晶的状态图； 图 9为具有图 7所示的结构的液晶显示面板在通电时液晶的状态图。 具体实施方式
为使本发明实施例的目的、 技术方案和优点更加清楚， 下面将结合本发 明实施例的附图，对本发明实施例的技术方案进行清楚、 完整地描述。显然， 所描述的实施例是本发明的一部分实施例， 而不是全部的实施例。 基于所描 述的本发明的实施例， 本领域普通技术人员在无需创造性劳动的前提下所获 得的所有其他实施例， 都属于本发明保护的范围。
本发明的实施例提供了一液晶显示面板和显示装置， 以降低能耗、 提高 色调分辨率和色彩的鲜艳度。
下面参照图 1至图 5详细说明本发明实施例提供的液晶显示面板。 图 1 为本发明实施例提供的一种液晶显示面板的结构的示意图。 图 2为本发明实 施例提供的另一种液晶显示面板的结构的示意图。 图 3为本发明实施例提供 的液晶显示面板的阵列基板的结构的俯视图。 图 4为具有图 1所示的结构的 液晶显示面板在通电时液晶的状态图。 图 5为具有图 2所示的结构的液晶显 示面板在通电时液晶的状态图。
如图 1所示， 本发明实施例提供的液晶显示面板例如包括对盒成型的彩 膜基板 1和阵列基板 2,彩膜基板 1和阵列基板 2之间填充有液晶 3 ,在彩膜 基板 1和阵列基板 2上分别设置有取向膜 6。 在本发明的实施例中， 液晶 3 在彩膜基板 1处的取向方向不同于在阵列基板 2处的取向方向。
在本发明的一些实施例中， 如图 1所示， 液晶 3在彩膜基板 1处的取向 方向为垂直取向， 并且液晶 3在阵列基板 2处的取向方向为水平取向， 但是 本发明的实施例不限于此。 在本发明的一些实施例中， 如图 2所示， 液晶 3 在彩膜基板 1处的取向方向为水平取向， 并且液晶 3在阵列基板 2处的取向 方向为垂直取向。
如上所述， 在本发明实施例提供的液晶显示面板中， 由于液晶分子釆用 混合取向模式， 因此降低了能耗、 提高色调分辨率和色彩的鲜艳度。
在本发明的实施例中， 如图 3所示， 阵列基板 2可以包括第一像素电极
4和第二像素电极 5 ,第一像素电极 4和第二像素电极 5设置在同一层中并且 彼此间隔设置。
在本发明的实施例中， 阵列基板 2可以还包括第一 TFT开关 7和第二 TFT开关 10、 第一源极线 8和第二源极线 11以及第一栅极线 9和第二栅极 线 12。第一像素电极 4通过第一 TFT开关 7与第一源极线 8和第一栅极线 9 相连接，而第二像素电极 5通过第二 TFT开关 10与第二源极线 11和第二栅 极线 12相连接。 第一源极线 8与第二源极线 11相平行， 第一栅极线 9与第 二栅极线 12相平行， 第一源极线 8与第一栅极线 9相垂直。
在本实施例中， 如图 3所示， 第一像素电极 4和第二像素电极 5可以为 梳状电极，但是本发明的实施例不限于此。 例如， 在本发明的一些实施例中， 第一像素电极 4和第二像素电极 5还可以为条状电极。
在液晶显示面板通电时， 向第一像素电极 4和第二像素电极 5分别施加 周期相同、 振幅大小相同并且极性相反的交流电信号。 此时， 本发明实施例 提供的液晶显示面板具有如图 4和图 5所示的液晶状态， 其中图 4为具有图 1所示的结构的液晶显示面板在通电时液晶的状态图， 图 5为具有图 2所示 的结构的液晶显示面板在通电时液晶的状态图。
在本发明的实施例中， 在液晶显示面板通电时， 由于对两个间隔设置的 梳状或条状像素电极施加周期相同、 振幅大小相同并且极性相反的交流电信 号， 因此增加了两像素电极的电势差而有利于液晶偏转， 从而提高了透过率 并且降低了能耗。 下面参照图 6至图 9详细说明本发明另一实施例提供的液晶显示面板。 图 6为本发明另一实施例提供的一种液晶显示面板的结构的示意图。 图 7为 本发明另一实施例提供的另一种液晶显示面板的结构的示意图。 图 8为具有 图 6所示的结构的液晶显示面板在通电时液晶的状态图。 图 9为具有图 7所 示的结构的液晶显示面板在通电时液晶的状态图。
如图 6所示， 本发明另一实施例提供的液晶显示面板具有与本发明的上 述实施例提供的液晶显示面板基本上相同的结构， 除了阵列基板 2还包括公 共电极层 13以及在公共电极层 13与第一像素电极 4和第二像素电极 5之间 设置的透明绝缘层 14。
在液晶显示面板通电时， 向第一像素电极 4和第二像素电极 5分别施加 周期相同并且极性相反的交流电信号，向公共电极层 13施加直流电信号。交 流电信号的极大电压值为向公共电极层 13 施加的直流电信号的电压值加上 一个预设的固定值 A V,并且交流电信号的极小电压值为向公共电极层 13施 加的直流电信号的电压值减去预设的固定值 A V。 此时， 本发明实施例提供 的液晶显示面板具有如图 8和图 9所示的液晶状态， 其中图 8为具有图 6所 示的结构的液晶显示面板在通电时液晶的状态图， 图 9为具有图 7所示的结 构的液晶显示面板在通电时液晶的状态图。
在本发明的实施例中， 在液晶显示面板通电时， 由于对两个间隔设置的 梳状或条状像素电极施加交流电信号， 因此更有利于液晶偏转， 从而提高了 透过率并且降低了能耗。 此外， 在本实施例中， 公共电极层的设置有利于增 强竖直方向的电场， 有利于竖直方向的液晶向水平方向偏转， 从而增大透过 率。
本发明的实施例还提供一种显示装置， 其包括上述液晶显示面板。 本发 明的实施例提供的显示装置可以包括： 电子纸、 手机、 电视、 数码相框等等 显示设备。
本发明实施例提供的显示装置因其所釆用的液晶显示面板的液晶分子釆 用混合取向模式， 降低了能耗、 提高色调分辨率和色彩的鲜艳度。
以上实施例仅用以说明本发明的技术方案， 而非对其限制； 尽管参照前 述实施例对本发明进行了详细的说明， 本领域的普通技术人员应当理解： 其 依然可以对前述各实施例所记载的技术方案进行修改， 或者对其中部分技术 特征进行等同替换； 而这些修改或者替换， 并不使相应技术方案的本质脱离 本发明各实施例技术方案的精神和范围。
