Description

一种液晶面板及显示装置 技术领域
本发明的实施例涉及液晶显示技术领域， 特别涉及一种液晶面板及显示 装置。 背景技术
现有的宽视角液晶面板主要包括： 平面转换 IPS ( In-Plane Switching )面 板和高级超维场转换（AD-SDS, Advanced Super Dimension Switch, 筒称 ADS ) 面板。 IPS面板最大的特点就是 IPS面板的像素电极和公共电极都在 同一个面上， 而不像其它液晶面板的电极是在上下两面， 立体排列。 ADS技 术是液晶分子界为解决大尺寸、 高清晰度桌面显示器和液晶分子电视应用而 开发的广视角技术， 也就是现在俗称的硬屏技术的一种。 ADS模式液晶显示 面板通过同一平面内狭缝电极边缘所产生的电场以及狭缝电极层与板状电极 层间产生的电场形成多维电场， 使液晶盒内狭缝电极间、 电极正上方所有取 向液晶分子都能够产生旋转， 从而提高了液晶工作效率并增大了透光效率。
图 1是第一种现有液晶面板的像素结构示意图，该液晶面板为 IPS面板， 其中， 直线箭头表示像素电极 110所形成电场的方向， 曲线箭头表示液晶分 子 120在电场作用下旋转的方向， 在相邻像素电极 110之间还设置有公共电 极 130。 图 2是第一种现有液晶面板的透过率与电压关系曲线， 其中， 每条 曲线对应的透过率变化范围为液晶面板在相应视角从全黑至全白， 所有曲线 的极角均为 60度， 方位角从 0度到 150度之间变化， 变化步长为 30度。 即 在极角为 60度， 方位角 （图中 Phi )分别为 0度、 30度、 60度、 90度、 120 度和 150度时分别令液晶面板的透过率从全黑至全白变化， 模拟得到透过率 和电压（单位伏） 的一条关系曲线。 从图 2可以看到， 不同视角 （极角相同 时即不同方位角）对应的 6条透过率与电压关系曲线， 严重， 差异较大， 没有 4艮好的重合性， 这就导致不同视角下的灰阶曲线不同， 因此会造成在同 一电压下的透过率不同， 也就是灰阶不同， 从而导致视角较差。 另一方面， 由于不同视角下的透过率不同， 不同视角下对应的液晶分子的各向异性状态 不同， 颜色差异也较大， 即所谓的 色偏移 ( 发明内容

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。 以下实施例用于说明本发 明， 但不用来限制本发明的范围。
本发明的实施例提供一种液晶面板及显示装置。 其中， 所述液晶面板包 括液晶层和像素区； 所述像素区包括多个像素单元， 每个像素单元都包括： 第一附属区和第二附属区。
在初始状态， 即所述液晶层未受到电场作用时， 所述第一附属区对应的 所述液晶层的液晶分子的长轴方向和所述第二附属区对应的所述液晶层的液 晶分子的长轴方向间夹角为 90度。
筒单起见， 本发明下述实施例中的液晶分子都是以正性液晶分子为例进 行说明的。 并且， 本发明提到的所有与液晶分子相关的夹角都是液晶分子在 初始状态下得到的。
所述第一附属区包括至少两个附属子区， 所述第二附属区包括至少一个 附属子区。 所述第一附属区和所述第二附属区的附属子区中分别设置有用于向所述 液晶层施加共面电场的至少两个电极， 所述两个电极中至少一个包含条状电 极。
所述第一附属区包括的两个附属子区为第一附属子区和第二附属子区， 所述第一附属子区的条状电极与所述第二附属子区的条状电极之间的夹角大 于 0度且小于 180度。
当所述第一附属区和所述第二附属区的附属子区中相应的至少两个电极 之间存在电压差时， 即形成向所述液晶层施加的所述共面电场， 在所述共面 电场作用下， 各附属子区对应的液晶层中的液晶分子向着所述共面电场的电 场方向旋转， 从而可以改善现有液晶面板视角较差及不同视角下色偏移严重 的问题。
实施例 1
图 3a是本发明实施例 1所述液晶面板的像素单元结构示意图， 图 3b是 图 3a中 A-A向的截面图。 本实施例所述液晶面板为 IPS面板， 所述液晶面 板包括液晶层和像素区， 像素区包含多个像素单元， 每个像素单元中电极结 构如图 3a所示。 每个像素单元都包含像素电极 330和公共电极 350, 其中所 有的像素电极 330都连接在一起， 所有的公共电极 350也都连接在一起， 只 是图 3a中未示出。
所述像素单元包括： 第一附属区 310和第二附属区 320。 可以看到在初 始状态， 第一附属区 310和第二附属区 320对应的液晶层的液晶分子的长轴 方向的夹角为 90度。 所述第一附属区 310进一步包括： 第一附属子区 311 和第二附属子区 312; 所述第二附属区 320进一步包括： 第三附属子区 321 和第四附属子区 322。
所述第一附属区和所述第二附属区的附属子区中分别设置有用于向所述 液晶层施加共面电场的至少两个电极， 所述两个电极中至少一个电极包含条 状电极。 例如， 在图 3a中， 所述第一附属子区 311、 所述第二附属子区 312、 所述第三附属子区 321和所述第四附属子区 322均包括能形成共面电场的两 个电极， 这两个电极都包含条状电极。 在本实施例中， 这两个电极分别为像 素电极 330和公共电极 350, 进一步地， 位于同一附属子区中的条状电极具 有相同的长度方向， 不同附属子区中的条状电极的长度方向不同。 例如， 第 一附属区的两个附属子区中的条状电极之间的夹角大于 0度且小于 180度， 第二附属区的两个附属子区中的条状电极之间的夹角大于 0度且小于 180度。 并且， 所述像素电极 330和所述公共电极 350交替间隔设置。
当所述像素电极 330和所述公共电极 350之间不存在电压差时， 所述第 一附属区 310对应的所述液晶层的液晶分子 340的长轴方向和所述第二附属 区 320对应的所述液晶层的液晶分子 340的长轴方向间夹角为 90度。当所述 像素电极 330和所述公共电极 350之间存在电压差时， 形成共面电场， 每个 附属子区对应的液晶层的液晶分子 340的长轴方向均沿图中曲线箭头所示方 向向该附属子区的电场方向 （图中直实线箭头方向）旋转。
在初始状态，所述第一附属子区 311中的条状电极（对应于图 3a中的像 素电极 330和公共电极 350 )具有第一长度方向 （图 3a中第一附属子区 311 中倾斜的直虚线箭头方向） ， 所述第一长度方向与所述第一附属子区 311对 应的液晶层的液晶分子 340的长轴方向间夹角为第一夹角 （图 3a中的 al )。 所述第二附属子区 312中的条状电极具有第二长度方向（图 3a中第二附属子 区 312中倾斜的直虚线箭头方向 ) , 所述第二长度方向与所述第二附属子区 312对应的液晶层的液晶分子 340的长轴方向间夹角为第二夹角（图 3a中的 a2 )。 所述第三附属子区 321中的条状电极具有第三长度方向（图 3a中第三 附属子区 321中倾斜的直虚线箭头方向） ， 所述第三长度方向与所述第三附 属子区 321对应的液晶层的液晶分子 340的长轴方向间夹角为第三夹角 （图 3a中的 a3 ) 。 所述第四附属子区 322 中的条状电极具有第四长度方向 （图 3a中第四附属子区 322中倾斜的直虚线箭头方向）， 所述第四长度方向与所 述第四附属子区 322对应的液晶层的液晶分子 340的长轴方向间夹角为第四 夹角 （图 3a中的 a4 )。
进一步地， 所述第一长度方向、 所述第二长度方向、 所述第三长度方向 和所述第四长度方向互不相同， 从而对应不同的附属子区。 例如， 所述第一 夹角 al等于所述第二夹角 a2。 进一步地， 所述第三夹角 a3等于所述第四夹 角 a4。
一种实施方式中， 所述第一夹角、 所述第二夹角、 所述第三夹角和所述 第四夹角均相等。
进一步地， 本实施例中， 所述第一夹角、 所述第二夹角、 所述第三夹角 和所述第四夹角的取值范围均为 3至 30度， 例如， 上述夹角的取值范围为 11度至 20度。
图 3a中的液晶分子是以正性液晶为例进行说明的，所述液晶层的液晶分 子也可以是负性液晶分子。 当液晶分子为负性液晶分子时， 第一附属区的液 晶分子的短轴方向与所述第一附属区的两个附属子区的条状电极的长度方向 之间的夹角， 以及第二附属区的液晶分子的短轴方向与所述第二附属区的两 个附属子区的条状电极的长度方向之间的夹角的取值范围均为 3至 35度,例 如， 上述夹角的取值范围为 11度至 20度。
另一实施方式中， 所述第一附属子区 311、所述第二附属子区 312、所述 第三附属子区 321和所述第四附属子区 322的面积均相等。
图 3c是本发明实施例 1所述液晶面板的透过率与电压关系曲线， 其中， 图中 6条曲线的极角均为 60度， 方位角 （图中 Phi )从 0度到 150度之间变 化， 变化步长为 30度， 即在极角为 60度， 方位角分别为 0度、 30度、 60 度、 90度、 120度和 150度时分别令液晶面板的透过率从全黑至全白变化， 模拟得到透过率和电压 （单位伏） 的一条关系曲线， 共模拟得到图中 6条曲 线。 从图 3c可以看到， 不同视角 （极角相同时即不同方位角）对应的 6条透 过率与电压关系曲线， 其重合度明显高于现有技术的液晶面板， 这表示不同 视角下的灰阶曲线接近，透过率接近，对应的液晶分子的各向异性状态接近， 从而改善了现有液晶面板视角较差及不同视角下色偏移严重的问题。 实施例 2
图 4a是本发明实施例 2的液晶面板的像素结构平面图， 图 4b是图 4a 中 B-B向的截面图。 本实施例基于实施例 1进行描述， 本实施例中的液晶面 板为 ADS面板， 参见图 4b, 所述 ADS面板包括液晶层和像素区， 像素区包 含多个像素单元， 每个像素单元设置有像素电极 430和公共电极 450。
参见图 4a, 本实施例中每个像素单元都包括： 第一附属区 410和第二附 属区 420。 所述第一附属区 410进一步包括： 第一附属子区 411和第二附属 子区 412; 所述第二附属区 420进一步包括： 第三附属子区 421和第四附属 子区 422。
所述第一附属子区 411、 所述第二附属子区 412、 所述第三附属子区 421 和所述第四附属子区 422均包括用于向所述液晶层施加共面电场的至少两个 电极， 这两个电极一个包含条状电极（本实施例 2中的包含条状电极的电极 就是 ADS模式中的狭缝电极） ， 另一个为板状电极。 具体的这两个电极一 个是公共电极， 一个是像素电极， 在本实施例中，公共电极 450为板状电极， 像素电极 430包含条状电极，需要说明的是，公共电极也可以包含条状电极， 对应的像素电极就为板状电极。
当所述像素电极 430和所述公共电极 450之间不存在电压差时， 所述第 一附属区 410对应的所述液晶层的液晶分子 440的长轴方向和所述第二附属 区 420对应的所述液晶层的液晶分子 440的长轴方向间夹角为 90度。当所述 像素电极 430和所述公共电极 450之间存在电压差时， 形成共面电场， 每个 附属子区对应的所述液晶层中的液晶分子 440的长轴方向均沿该附属子区的 电场方向旋转。
类似于实施例 1 , 在初始状态， 本实施例所述第一附属区 410对应的所 述液晶层的液晶分子 440的长轴方向与所述第一附属区 410的两个附属子区 的条状电极之间的夹角相同； 所述第二附属区 420对应的所述液晶层的液晶 分子 440的长轴方向与所述第二附属区 420的两个附属子区的条状电极之间 的夹角相同。 例如， 本实施例中， 所述第一附属区 410对应的所述液晶层的 液晶分子 440的长轴方向与所述第一附属区 410的两个附属子区的条状电极 之间的夹角， 等于所述第二附属区 420对应的所述液晶层的液晶分子 440的 长轴方向与所述第二附属区 420的两个附属子区的条状电极之间的夹角。
本实施例中在初始状态， 所述第一附属区 410对应的所述液晶层的液晶 分子 440的长轴方向与所述第一附属区 410的两个附属子区的条状电极之间 的夹角， 以及所述第二附属区 420对应的所述液晶层的液晶分子 440的长轴 方向与所述第二附属区 420的两个附属子区的条状电极之间的夹角的取值范 围均为 3至 30度。 例如， 上述夹角的取值范围为 5至 14度。
图 4a中的液晶分子是以正性液晶为例进行说明的，需要说明的是该液晶 分子也可以为负性液晶， 具体地， 当液晶分子为负性液晶分子时， 第一附属 区的液晶分子的短轴方向与所述第一附属区的两个附属子区的条状电极之间 的夹角， 以及所述第二附属区的液晶分子的短轴方向与所述第二附属区的两 个附属子区的条状电极之间的夹角的取值范围均为 3至 35度。例如，上述夹 角的取值范围为 5至 14度。
同时， 本实施例中， 所述第一附属子区 411、 所述第二附属子区 412、 所 述第三附属子区 421和所述第四附属子区 422的面积也均相等。
另夕卜，图 4a中还示出了设置于所述像素区周围的栅线 460和数据线 470。 图 4c是本实施例 2所述液晶面板的像素结构的一种变形示意图，其与图
4a所述像素结构的不同在于， 所述第二附属区的两个的附属子区， 即第三附 属子区 421和第四附属子区 422分离设置于所述第一附属区 410的两侧。 需 要说明的是， 图 4c只是给出了一种变形，本发明并不限定所述像素区所包括 的不同附属子区之间的位置关系， 比如， 所述第一附属区 410的两个附属子 区也可以分离设置。
另外， 本发明所述像素区中第一附属区和第二附属区都包含两个附属子 区域， 需要说明的是第一附属区可以是两个或者更多的子区域， 第二附属区 也可以是一个以上的附属子区域， 这样都能在显示时形成 3个以上的互不相 同的液晶取向， 进而形成多畴显示， 提高液晶面板的视角， 4艮好地解决了色 偏问题。 实施例 3
本发明还提供一种显示装置， 所述显示装置包括上述实施例所述的液晶 面板， 所述显示装置可以液晶电视、 液晶显示器、 笔记本电脑、 平板电脑、 智能手机等。 本发明实施例所述液晶面板及显示装置， 令液晶面板像素区的像素单元 包括第一附属区和第二附属区， 在初始状态， 两个附属区中的液晶分子的长 轴方向间夹角呈 90度，第一附属区包括两个附属子区，第二附属区包括一个 或者两个附属子区， 第一附属区和第二附属区的附属子区中分别设置有用于 向液晶层施加共面电场的至少两个电极， 所述至少两个电极中至少一个包含 条状电极； 第一附属区的两个附属子区中的条状电极之间的夹角大于 0度且 小于 180度， 当所述两个电极形成共面电场时， 每个附属子区中的液晶分子 的长轴方向均向该附属子区的电场方向旋转， 从而可以改善现有液晶面板视 角较差及不同视角下色偏移严重的问题。 以上实施方式仅用于说明本发明， 而并非对本发明的限制， 有关技术领 域的普通技术人员， 在不脱离本发明的精神和范围的情况下， 还可以做出各 种变化和变型， 因此所有等同的技术方案也属于本发明的范畴， 本发明的保 护范围应由权利要求限定。
