Description

一种液晶显示面板及液晶显示装置 技术领域
本发明涉及液晶显示面板领域，尤其涉及一种液晶显示面板及液晶显示装置。
背景技术
UV2A(Ultraviolet Vertical Alignment) 技术是一种采用紫外线对垂直配向液晶显示面板中的液晶进行配向的技术，其基本原理是在玻璃基板上涂有对紫外线具有反应的高分子材料的配向膜，在紫外线的照射下，配向膜表面的高分子主链会沿着紫外线照射的方向倾斜，从而使得液晶分子可以沿着这个主链方向倾斜。目前这种技术主要应用在具有大视角的垂直配向模式液晶显示器上，提高了大视角液晶显示器的开口率、对比度、响应速度等特性。
如图 1 所示，图 1 为现有的液晶显示面板中万字暗纹的图形示意图；由于 UV2A 技术采用特殊的正交垂直光配相方式，使得液晶显示面板在亮态时，在子像素上形成万字暗纹，万字暗纹的出现降低了液晶显示面板的透光率；另外，现有的液晶显示面板侧视时会有严重的 washout （俗称洗白）问题，亦即侧视时，由于亮度变高而使画面变白的情况，使得侧视时的显示品质明显的下降。

下面结合附图，通过对本发明的具体实施方式详细描述，将使本发明的技术方案及其它有益效果显而易见。

 本发明的最佳实施方式
为更进一步阐述本发明所采取的技术手段及其效果，以下结合本发明的优选实施例及其附图进行详细描述。
请参照图 2 及图 3 ，其中，图 2 为本发明液晶显示面板的优选实施例的结构示意图；图 3 为本发明液晶显示面板的优选实施例的一个像素单元对应的像素电极结构示意图。
本优选实施例的液晶显示面板 10 ，包括：第一基板 101 、第二基板 102 、液晶层 103 、第一偏光片 104 、第二偏光片 105 、第一配向膜 106 以及第二配向膜 107 ；其中，第一偏光片 104 位于第一基板 101 外侧，第一配向膜 106 位于第一基板 101 内侧，第二偏光片 105 位于第二基板 102 外侧，第二配向膜 107 位于第二基板 102 内侧。
第一基板 101 上设置有多个像素电极 20 ，每个像素电极 20 对应一个像素单元，其中，每个像素电极 20 包括一水平主干电极 201 和一竖直主干电极 202 ，水平主干电极 201 和竖直主干电极 202 将像素电极对应的像素单元划分为四个透光区，且相邻透光区具有不同的配向方向。像素电极 20 还包括位于四个透光区内的多条枝干电极 203 ，枝干电极 203 平行于水平主干电极 201 或竖直主干电极 202 ，使得透光区内的配向方向平行于位于透光区内的枝干电极。
相邻透光区内的枝干电极 203 互相垂直，具体地，四个透光区分别为：第一透光区 204 、第二透光区 205 、第三透光区 206 以及第四透光区 207 ，位于第一透光区 204 以及第三透光区 206 内的枝干电极 203 平行于水平主干电极 201 ，并且位于第一透光区 204 内的枝干电极 203 的一端以及位于第三透光区 206 内的枝干电极 203 的一端汇聚于竖直主干电极 202 上；位于第二透光区 205 以及第四透光区 207 内的枝干电极 203 平行于竖直主干电极 202 ，并且，位于第二透光区 205 内的枝干电极 203 的一端以及位于第四透光区 207 内的枝干电极 203 的一端汇聚于水平主干电极 201 上。
优选的，水平主干电极 201 和竖直主干电极 202 的宽度介于 3 微米至 8 微米之间；位于四个透光区内的枝干电极 203 的宽度介于 2 微米至 4 微米之间。同一透光区内的相邻枝干电极 203 之间具有一狭缝 208 ，狭缝 208 的宽度介于 2 微米至 4 微米之间。
本优选实施例通过将像素电极 20 划分为水平主干电极 201 、竖直主干电极 202 以及多条枝干电极 203 ，并且位于同一透光区内的枝干电极 203 之间具有一狭缝 208 ，狭缝 208 处的电场将诱导该处的液晶分子发生相应的偏转，增加透光率，从而减弱液晶显示面板中出现的暗纹。
另外，本优选实施例的四个透光区内的配向方向为水平方向和竖直方向，具体地，第一透光区内的配向方向为水平向左，第二透光区内的配向方向为竖直向下，第三透光区内的配向方向为水平向右，第四透光区内的配向方向为竖直向上，形成这四个透光区内的不同配向方向的原理如下：
首先，参阅图 4 ，图 4 为本发明液晶显示面板的优选实施例的配向预倾角示意图。第一配向膜 301 与第二配向膜 302 采用 UV2A 技术实现两个预倾角方向：水平方向和竖直方向，第一配向膜 301 的预倾角方向为交替排列的竖直向下方向和竖直向上方向，第二配向膜 302 的预倾角方向为交替排列的水平向左方向和水平向右方向，每个像素单元包括第一配向膜 301 的一对竖直向下和竖直向上的预倾角方向，以及第二配向膜 302 的一对水平向左和水平向右的预倾角方向，因此，每个像素单元 303 包括四个预倾角方向区域，分别为左上方区域 304 、左下方区域 305 、右下方区域 306 和右上方区域 307 。例如，在左上方区域 304 中，由于第一配向膜 301 的预倾角方向呈竖直向上方向，第二配向膜 302 的预倾角方向呈水平向左方向，因此，处于左上区域 304 内的液晶分子的配向方向的预倾角方向将向左上方倾斜。其他区域中液晶分子的配向方向同理可知，可参照图 4 所示，在此不做具体描述。
接着，结合像素电极的结构（参阅图 3 ），在液晶显示面板处于亮态时，形成四个透光区内的不同配向方向。具体地，左上方区域 304 对应第一透光区 204 内的像素电极的结构，包括水平主干电极 201 的右半部分和竖直主干电极 202 的上半部分以及多条平行于水平主干电极 201 的枝干电极 203 ，进而形成第一透光区 204 内水平向左的配向方向；左下方区域 305 对应第二透光区 205 内的像素电极的结构，包括水平主干电极 201 的左半部分和竖直主干电极 202 上半部分以及多条平行于竖直主干电极 202 的枝干电极 203 ，进而形成第二透光区 205 内竖直向下的配向方向；右下方区域 306 对应第三透光区 206 内的像素电极的结构，包括水平主干电极 201 的左半部分和竖直主干电极 202 下半部分以及多条平行于水平主干电极 201 的枝干电极 203 ，进而形成第三透光区 206 内水平向右的配向方向；右上方区域 307 对应第四透光区 207 内的像素电极的结构，包括水平主干电极 201 的右半部分和竖直主干电极 202 下半部分以及多条平行于竖直主干电极 202 的枝干电极 203 ，进而形成第四透光区 207 内竖直向上的配向方向。
优选地，第一偏光片与枝干电极之间的夹角为 45 度角，并且，第一偏光片和第二偏光片之间的夹角为 90 度，这样进一步使得液晶显示面板可以获得较高的透光率。
参阅图 5 ，图 5 为本发明液晶显示面板优选实施例的液晶分子倾倒方向示意图。于图示中显示第一方向 X 、一第二方向 y 及一第三方向 Z ，第一方向 X 、第二方向 y 及第三方向 Z 实质上是两两相互垂直。其中，第一方向 X 与显示面板的扫描线的延伸方向实质上平行，第二方向 y 与显示面板的数据线的延伸方向实质上平行，且第三方向 Z 为垂直第一方向 X 与第二方向 y 的另一方向。
当像素单元为亮态且液晶分子的最终位置的 Phi 角与第一偏光片的夹角为 45/135/225/315 度，且 theta 角为 90 度时，液晶分子的穿透效率最好 (Phi 角为液晶长轴方向于 X-y 平面上的投影与 X 方向之间的夹角， theta 角为液晶分子的长轴方向与 Z 方向之间的夹角 ) 。本实施例是利用数据线将对应的数据电压传送至像素单元，并通过像素电极与公共电极之间所产生的电场与液晶分子的预倾角方向于 X-y 平面的投影分量的合力，使亮态时的液晶分子的长轴方向倾倒于与第一偏光片的夹角为 45/135/225/315 度的位置，借此使液晶分子的穿透效率最好。
另外，于现有技术中的液晶显示面板的驱动中，液晶分子被电场驱动时，其 theta 角会随着灰阶的不同而往 90 度的角度产生变化，但是 Phi 角于不同灰阶驱动时是直接倒向 45/135/225/315 度，并不会随着灰阶的不同而有所变化。本发明通过上述像素电极与配向方向的设计，使液晶分子的 Phi 角随着灰阶的不同渐变至 45/135/225/315 度，使得显示面板具有 IPS 型或 FFS 型的光学特性表现。换言之，本实施例的像素电极对应的液晶分子在亮态时同时有 theta 角与 Phi 角的变化，因此可改善现有技术液晶显示面板的洗白问题，使液晶显示面板具有较佳的侧视效果。
本发明的液晶显示面板，通过将像素电极划分为水平主干电极、竖直主干电极以及多条枝干电极，不仅可以减弱液晶显示面板中出现的暗纹，进而提高了液晶显示面板的透光率，而且可以改善现有技术中液晶显示面板侧视时的洗白问题，使液晶显示面板具有较佳的侧视效果。

综上，虽然本发明已以优选实施例揭露如上，但上述优选实施例并非用以限制本发明，本领域的普通技术人员，在不脱离本发明的精神和范围内，均可作各种更动与润饰，因此本发明的保护范围以权利要求界定的范围为准。
