Description

阵列基板、 液晶显示面板和液晶显示器 技术领域
本发明实施例涉及一种阵列基板、 液晶显示面板和液晶显示器。 背景技术
薄膜晶体管液晶显示器 ( Thin Film Transistor-Liquid Crystal Display, TFT-LCD )是利用夹在液晶层上电场强度的变化， 改变液晶分子的取向， 从 而控制透光的强弱来显示图像的。 一般来讲， 一块完整的液晶显示面板必须 具有背光模块、 偏光片、 下基板和上基板以及由它们两块基板组成的盒中填 充的液晶分子层构成。
在液晶显示器中产生的电场与基板平面大致垂直， 用于控制液晶分子的 状态。 这种液晶显示器一般被称为垂直电场型液晶显示器。 在垂直电场型液 晶显示器中， 夹持液晶层的下基板上形成有第一电极， 上基板上形成有第二 电极， 加载电压后将会形成从第一电极发出， 面向第二电极的与基板平面大 致垂直的电场。
在液晶显示器中产生的电场与基板平面大致平行， 用于控制液晶分子的 状态。 这种液晶显示器一般被称为横向电场型液晶显示器。 在横向电场型液 晶显示器中， 夹持液晶层的下基板上一般形成有第一电极和第二电极， 加载 电压后将会形成从第一电极发出， 面向第二电极的与基板平面大致平行的电 场。
在现有技术中， 也有结合垂直电场和横向电场的优势， 制造出既有垂直 电场又有横向电场的液晶显示器。 如图 1所示， 液晶显示器包括上基板 5和 下基板 6, 以及填充在上基板 5和下基板 6之间的液晶层 30。 其中， 上基板 5包括位于靠近所述液晶层 30—侧的第一电极（公共电极） 1 , 下基板 6包 括位于靠近所述液晶层 30—侧的第二电极（公共电极） 2和第三电极（像素 电极） 3。 加载电压后， 第一电极 1与第二电极 2电势相等， 相互之间不产生 电场。 第一电极 1与第三电极 3之间电势不等， 产生垂直于基板平面的垂直 电场。 第二电极 2与第三电极 3之间电势不等， 产生平行于基板平面的横向 电场。
比起横向电场型液晶显示器， 既有垂直电场又有横向电场的液晶显示器 可以减少明暗条紋的数量。 但发明人发现， 这种基板中的第二电极 2与第三 电极 3之间的间隔区域中， 液晶分子的偏转程度仍然有所不足， 从而导致相 应的区域不够明亮， 即会影响液晶显示器的显示质量。 在这种情况下， 如果 需要保证足够的亮度， 则需要增加第二电极 2与第三电极 3的驱动电压。 发明内容
本发明的实施例提供一种阵列基板、 液晶显示面板和液晶显示器， 在显 示面板中同时具有垂直电场和横向电场， 使其垂直电场分布较为均匀， 提高 了液晶显示器的显示质量。
根据本发明实施例的一方面， 提供了一种阵列基板， 对应于多个像素区 域， 该阵列基板的每个像素区域包括位于靠近所述液晶层一侧的第二电极和 第三电极， 所述第二电极包括至少一个第二电极条， 所述第三电极包括至少 一个第三电极条；
所述阵列基板的每个像素区域还包括位于靠近所述液晶层一侧的第四电 极， 所述第四电极包括至少一个第四电极条， 该第四电极条位于相邻的所述 第二电极条与所述第三电极条之间； 且所述第四电极的电位处于所述第二电 极的电位与所述第三电极的电位之间。
在本发明实施例中， 所述下基板的每个像素区域中， 所述第二电极条、 所述第三电极条、 所述第四电极条各有多个， 且各所述第二电极条彼此电连 接， 各所述第三电极条彼此电连接， 各所述第四电极条彼此电连接。
在本发明实施例中， 所述第二电极条、 所述第三电极条、 所述第四电极 条的宽度彼此不同。
在本发明实施例中， 所述第二电极条、 所述第三电极条、 所述第四电极 条处于同一平面。
在本发明实施例中， 所述第四电极处于电悬空状态。
在本发明实施例中， 所述第二电极条与所述第四电极条之间间隔的宽度 和所述第三电极条与所述第四电极条之间间隔的宽度不同。
在本发明实施例中， 所述第二电极条与所述第四电极条之间间隔的各个 宽度互不相同， 所述第三电极条与所述第四电极条之间间隔的各个宽度互不 相同。
在本发明实施例中， 所述第二电极条、 所述第三电极条和所述第四电极 条均弯折成 V状。
根据本发明实施例的另一方面， 提供了一种液晶显示面板， 包括对盒设 置的上基板和下基板， 以及填充在所述上基板和所述下基板之间的液晶层， 所述液晶层中的液晶分子的初始取向状态垂直于所述上基板和所述下基板； 所述下基板为上述的阵列基板。
在本发明实施例中， 所述上基板包括位于靠近所述液晶层一侧的第一电 极。
在本发明实施例中， 所述第一电极与所述第二电极相互连接。
在本发明实施例中， 所述上基板上还包括： 形成在所述第一电极上的保 护层。
根据本发明实施例的又一方面， 提供一种液晶显示器， 包括上述的液晶 显示面板。
本发明实施例提供的阵列基板、 液晶显示面板和液晶显示器， 在阵列基 板的相互间隔的第二电极与第三电极之间设置至少一个第四电极， 且第四电 极与第二电极、 第三电极均不连接， 在加载电压后， 第三电极与位于其两边 第四电极之间产生电场， 第四电极分别与位于其两边的第二电极和第三电极 之间产生电场， 由此，可在不增加第二电极与第三电极的驱动电压的情况下， 可使第二电极与第三电极之间的间隔区域中， 液晶分子的偏转程度增加， 从 而使相应区域的亮度增强， 进而能够提高液晶显示面板、 液晶显示器的显示 质量。进一步的，彩膜基板上可设置第一电极， 该第一电极与第二电极相连， 从而可使第一电极与第三电极， 第四电极均可产生垂直电场， 可减少液晶显 示器的明暗条紋的数量。 附图说明

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。
本发明实施例提供的阵列基板， 如图 2所示， 对应于多个像素区域， 该 阵列基板 6对应于每个像素区域包括位于靠近所述液晶层 30—侧的第二电极 2和第三电极 3 , 所述第二电极 2包括至少一个第二电极条， 所述第三电极 3 包括至少一个第三电极条。 此处的电极条例如可以是梳状电极的各个梳齿状 的电极部分。 例如， 第二电极条和第三电极条交替设置在阵列基板 6上。
所述阵列基板 6对应于每个像素区域还包括位于靠近所述液晶层 30—侧 的第四电极 4, 所述第四电极 4包括至少一个第四电极条， 该第四电极条位 于相邻的所述第二电极条与所述第三电极条之间； 且所述第四电极的电位处 于所述第二电极的电位与所述第三电极的电位之间。
在本发明一实施例中， 所述阵列基板 6对应于每个像素区域中， 所述第 二电极条、 所述第三电极条、 所述第四电极条各有多个， 且各所述第二电极 条彼此电连接， 各所述第三电极条彼此电连接， 各所述第四电极条彼此电连 接。 所述第二电极条、所述第三电极条、所述第四电极条可以处于同一平面。 在本发明一实施例中， 所述第四电极处于电悬空状态。
在本发明一实施例中， 所述第二电极 2的所述第二电极条、 所述第三电 极 3的所述第三电极条和所述第四电极 4的所述第四电极条的宽度可以相同 或不同。 参考图 7 , 所述第二电极条的宽度 、 所述第四电极条的宽度1)、 所 述第三电极条的宽度 c彼此不相同。
在本发明一实施例中， 阵列基板 6上的第二电极 2的第二电极条、 第三 电极 3的第三电极条和第四电极 4的第四电极条的宽度可以在平面上连续变 化。 例如， 第二电极条、 第三电极条和第四电极条均是在图面上方较宽， 在 图面下方较窄的连续变化的， 当然， 这只是示例， 其他形式的连续变化也可 以。
在本发明一实施例中， 进一步地， 阵列基板 6上的第二电极 2的第二电 极条、 第三电极 3的第三电极条和第四电极 4的第四电极条在平面上可以呈 阶梯状。例如， 第二电极条、第三电极条和第四电极条均是在图面上方较窄， 在图面下方较宽， 逐级阶梯式由窄变宽的， 当然， 这只是示例， 其他形式的 阶梯式变化也可以。
在本发明一实施例中， 所述第二电极条与所述第四电极条之间间隔的宽 度和所述第三电极条与所述第四电极条之间间隔的宽度可以相同或不同， 在 本发明实施例中， 例如， 如图 8所示， 所述第二电极条与所述第四电极条之 间的间隔宽度 d和所述第三电极条与所述第四电极条之间的间隔宽度 e不同。 例如，在一个像素区域中， 图面左侧的间隔若小于图面右侧的间隔的话， V-T 特性会不一样， 视角特性也更好。
在本发明一实施例中， 所述第二电极条与所述第四电极条之间间隔的各 个宽度互不相同， 所述第三电极条与所述第四电极条之间间隔的各个宽度互 不相同。
在本发明一实施例中， 所述第二电极条、 所述第三电极条和所述第四电 极条均弯折成 V状， 也可以为其他弯曲形状、 折线形状或为直线状。
本发明实施例提供的液晶显示面板， 如图 3至图 5所示， 包括对盒的上 基板（也可称为彩膜基板） 5和下基板（也可称为阵列基板） 6 , 以及填充在 上基板 5和下基板 6之间的液晶层 30,所述液晶层中的液晶分子的初始取向 状态垂直于所述上基板 5、所述下基板 6。所述液晶层中的液晶分子例如具有 正介电各向异性。
在本发明一实施例中， 所述上基板 5包括位于靠近所述液晶层一侧的第 一电极 1。 在本实施例中， 设定该第一电极 1为公共电极（Com电极） 。 然 而， 第一电极 1不是必需的， 上基板 5上也可以不设有第一电极 1。 所述下 基板 6对应于多个像素区域， 该下基板 6对应于每个像素区域包括位于靠近 所述液晶层 30—侧的第二电极 2和第三电极 3 ,所述第二电极 2包括至少一 个第二电极条， 所述第三电极 3包括至少一个第三电极条。 例如， 第二电极 条和第三电极条可以交替设置。
在本发明一实施例中， 所述下基板 6对应于每个像素区域还包括位于靠 近所述液晶层 30—侧的第四电极 4,所述第四电极 4包括至少一个第四电极 条， 该第四电极条位于相邻的所述第二电极条与所述第三电极条之间； 且所 述第四电极的电位处于所述第二电极的电位与所述第三电极的电位之间。
在本发明一实施例中，设定第二电极 2也为公共电极（Com电极）， 即， 第一电极 1与第二电极 2相互连接； 然而它们也可以设置为不相互连接并具 有不同的电位。 设定第三电极 3为像素电极 ( Pix电极） 。 其中， 在未加载 电压时， 液晶层 30中的液晶分子的取向（即初始取向）相对上基板 5、 下基 板 6垂直。
在本发明一实施例中， 所述下基板对应于每个像素区域中， 所述第二电 极条、 所述第三电极条、 所述第四电极条各有多个， 且各所述第二电极条电 连接、 各所述第三电极条电连接、 各所述第四电极条电连接。
在本发明一实施例中， 所述第二电极 2的所述第二电极条、 所述第三电 极 3的所述第三电极条和所述第四电极 4的所述第四电极条的宽度可以相同 或不同。 例如， 参考 7所示， 所述第二电极条的宽度&、 所述第四电极条的 宽度 b、 所述第三电极条的宽度 c彼此不相同。
在本发明一实施例中， 所述第四电极 4与第二电极 2、 第三电极 3位于 同一平面。 而且， 在相邻的第二电极 2、 第三电极 3的电极条之间， 可以设 有第四电极 4的多个电极条。且该第四电极 4与第一电极 1、 第二电极 2、和 第三电极 3均不连接， 即第四电极 4处于电悬空状态。 这样， 在电场的感应 下， 第四电极 4的电位处于第一电极 1或第二电极 2的电位与第三电极 3的 电位之间。
例如， 向液晶显示面板加载电压时， 可以设定加载到第一电极 1、 第二 电极 2上的电压 V 小于加载到第四电极 4上的电压 V2, 加载到第四电极 4 上的电压 V2小于加载到第三电极 3上的电压 V3。 即 ¼ < V2 < V3。 液晶显示 面板像素区域的等效电路图如图 6所示， 横纵交叉的栅线 11、 数据线 12定 义的像素区域内， 加载了三个电压， 分别是由数据线 12经 TFT 13传导到第 三电极 3的 V3, 由第一电极 1传导到第二电极 2的 ¼, 和单独传导到第四 电极 4的 V2, 三个电压之间的关系满足上述 ¼ < V2 < V3。
加载电压后，如图 3所示， 第一电极 1和第二电极 2之间等电势， 因此， 此二者之间不产生电场。 第三电极 3与第一电极 1之间产生垂直于基板平面 的垂直电场， 同时， 第三电极 3也与位于其两侧的第四电极 4之间产生平行 于基板平面的横向电场。 特别地， 在本实施例中， 第四电极 4还与第一电极 1之间产生垂直于基板平面的垂直电场， 同时， 第四电极 4还与位于其两侧 的第二电极 2、 第三电极 3之间产生平行于基板平面的横向电场。
总的来看， 在本实施例提供的液晶面板中， 第二电极 2、 第三电极 3和 第四电极 4之间分别产生横向电场， 可在不增加第二电极与第三电极的驱动 电压的情况下， 可使第二电极与第三电极之间的间隔区域中， 液晶分子的偏 转程度增加， 从而使相应区域的亮度增强， 进而能够提高液晶显示面板、 液 晶显示器的显示质量。 第三电极 3和第一电极 1之间产生垂直电场， 第四电 极 4和第一电极 1之间产生垂直电场，可减少液晶显示器的明暗条紋的数量， 也因此能够提高液晶显示面板的显示质量。
在本发明一实施例中， 下基板 6上的第二电极 2的第二电极条、 第三电 极 3的第三电极条和第四电极 4的第四电极条的宽度可以在平面上连续变化。 例如， 第二电极条、 第三电极条和第四电极条均是在图面上方较宽， 在图面 下方较窄的连续变化的， 当然， 这只是示例， 其他形式的连续变化也可以。
在本发明一实施例中， 进一步地， 下基板 6上的第二电极 2的第二电极 条、 第三电极 3的第三电极条和第四电极 4的第四电极条在平面上可以呈阶 梯状。 例如， 第二电极条、 第三电极条和第四电极条均是在图面上方较窄， 在图面下方较宽， 逐级阶梯式由窄变宽的， 当然， 这只是示例， 其他形式的 阶梯式变化也可以。 例如， 第二电极条、 第三电极条和第四电极条宽度缩小 方向相同， 即均是由图面下方朝向上方缩小， 当然也可以反过来， 由上方朝 向图面下方缩小。
在本发明一实施例中， 所述第二电极 2的第二电极条与所述第四电极 4 的第四电极条之间间隔的宽度和所述第三电极 3的第三电极条与第四电极 4 的第四电极条之间间隔的宽度可以相同或不同， 在本发明实施例中， 例如， 如图 8所示， 第二电极 2的第二电极条与第四电极 4的第四电极条之间的间 隔宽度 d和第三电极 3的第三电极条与第四电极 4的第四电极条之间的间隔 宽度 e不同。 在一个像素区域中， 图面左侧的间隔若小于图面右侧的间隔的 话， V-T特性会不一样， 视角特性也更好。
在本发明一实施例中， 所述第二电极 2的第二电极条与所述第四电极 4 的第四电极条之间间隔的各个宽度互不相同， 所述第三电极 3的第三电极条 与所述第四电极 4的第四电极条之间间隔的各个宽度互不相同。
此外， 所述第二电极 2的电极条、 所述第三电极 3的电极条、 所述第四 形状、 折线形状或为直线状。
本发明实施例提供的液晶显示面板中， 如图 4所示， 所述上基板 5还包 括形成在所述第一电极 1上的保护层 7。 相对没有保护层 7的结构， 具有保 护层 7能够使得电场的倾斜角度更大， 从而使相应区域的亮度增强， 进而能 够提高液晶显示面板。
此处需要说明的是， 所述下基板 6与上述的阵列基板 6对应， 所述上基 板 5与上述的彩膜基板 5对应， 因此使用相同的标号进行说明。
本发明实施例提供的液晶显示器， 包括上述实施例中提供的液晶显示面 板， 该液晶显示面板的结构与上述实施例相同， 在此不再赘述。
以上所述仅是本发明的示范性实施方式， 而非用于限制本发明的保护范 围， 本发明的保护范围由所附的权利要求确定。
