本发明的一个方面提供了一种狭缝电极， 以解决现有狭缝电极的 工艺余量较低的问题。 本发明的另一个方面提供了一种包括所述狭缝 电极的阵列基板。 本发明的另一个方面提供了一种包括所述阵列基板 的显示装置。
以下将结合附图对本发明提供的各个实施例进行说明。
参见图 2和图 3 , 根据本发明的实施例提供的狭缝电极包括： 至少 一个狭缝电极单元 1。 所述狭缝电极单元 1 包括： 多个条状电极 11 , 相邻两个条状电极 11之间具有狭缝； 其中， 每一个条状电极 11 具有 设定的平均宽度， 每一个狭缝电极单元 1 中的至少两个条状电极 11的 平均宽度不相等。
图 2所示的狭缝电极包括一个狭缝电极单元 1 ; 图 3所示的狭缝电 极包括两个狭缝电极单元 1。
由图 2和图 3中任一个所示的狭缝电极可知， 条状电极 11的平均 宽度不完全相等。 也就是说， 至少有两个条状电极平均宽度不相等， 所述至少两个条状电极中的一个的平均宽度为第一平均宽度， 另一个 的平均宽度为第二平均宽度。
根据该实施例所述的狭缝电极单元中的至少两个条状电极的平均 宽度不相等， 这样的设置方式可以提高制作狭缝电极的精度范围， 提 高狭缝电极的工艺余量。 在制作所述狭缝电极时， 其制作过程中的精 度范围较宽， 狭缝电极的工艺余量较高。
为了说明根据本发明的实施例提供的狭缝电极具有较高的工艺余 量， 本发明通过软件进行了模拟测试。 以狭缝电极为像素电极为例， 设计了两种结构的液晶显示面板， 对应下述实施例和比较例；
实施例： 液晶显示面板满足： 每一个条状电极的平均宽度与其他 任一个条状电极的平均宽度不相等， 液晶显示面板除像素电极之外的 其他结构与比较例中的液晶显示面板结构相同； 条状电极的平均宽度 按照排列顺序依次为： 2.0μιη、 2.2μιη、 2.4μιη、 2.6μιη、 2.8μιη。
比较例： 液晶显示面板满足： 每一个条状电极的平均宽度与其他 任一个条状电极的平均宽度相等， 并且为 2.4μιη。 对实施例和比较例中的狭缝电极的工艺余量进行了模拟测试， 并 且对狭缝电极的光透过率、 与公共电极之间的电容存储率进行了模拟 测试， 得到的模拟测试结果如下表一所示。
表一： 狭缝电极的工艺余量、 光透过率和电容存储率模拟结果
Figure imgf000007_0001
图 4 为上述实施例和比较例对应的产品光透过率与条状电极宽度 关系图。
当产品光透过率满足需求时， 比较例的工艺变动范围为 2.2〜2.6μιη, 可以表示为 2.4 ± 0.2μιη, 根据本发明的实施例工艺变动范 围为 2.0〜2.8μιη, 可以表示为 2.4 ± 0.4μιη。 制作狭缝电极的精度范围增 大了约一倍， 工艺余量提高。 产品在量产时更易于获得光透过率满足 需求的良品， 从而实现成本的节约。
在上述图 2和图 3所示的狭缝电极中， 狭缝电极单元 1 中的任一 个条状电极 11的平均宽度与其他条状电极 11的平均宽度不完全相等， 且有较多的实施方式。
例如， 按照每一个狭缝电极单元中的各条状电极 11的排列顺序， 每间隔 η个条状电极， 条状电极的平均宽度变化一次， 其中 η为正整 数。
狭缝电极单元中的各条状电极的宽度可以按照排列顺序递增或递 减， 按照排列顺序， 各条状电极的对应区域的光透过率递减或递增， 光透过率的变化趋势是一致的， 因此在视觉上不会出现突然某一区域 光透过率较大而某一区域光透过率较小的问题， 从而实现显示效果较 佳的目的。
每两个相邻的条状电极的平均宽度之间的差值可以是恒定的。
所述狭缝电极单元中的各条状电极的平均宽度范围为 2〜4μιη。 具 体实施时， 可以采用以下几种实施方式： 条状电极的宽度按照排列次 序依次可以为 2.2μιη、 2.4μιη、 2.6μιη、 2.8μιη、 3.0μιη等； 或者可以为 2.3μηι、 2.5μηι、 2.7μηι、 2.9μηι、 3. Ιμηι等； 或者还可以为 2.1μηι、 2.3μηι、 2.5μηι、 2.7μηι、 2.9μηι等。 电极的整体 构呈长 ^状分布， 所述条状 极的宽度处处相等， 或者 所述条状电极的宽度按照自身的延伸方向递增或递减。
也就是说， 条状电极的图案的两个长边为直线， 两个长边相互平 行或者不平行。
在上述任一实施方式的基础上， 可以设计出如图 3 所示的狭缝电 极， 即狭缝电极包括两个狭缝电极单元 1 , 两个狭缝电极单元 1中的条 状电极 11呈镜像分布。
狭缝电极单元内的条状电极平均宽度越宽， 光透过率越小， 条状 电极平均宽度越窄， 光透过率越大。 两个狭缝电极单元上的条状电极 呈镜像分布时， 若一个狭缝电极单元中从边缘到中心排列的各条状电 极的平均宽度依次递增 （或依次递减） ， 则另一个狭缝电极单元中从 边缘到中心排列的各条状电极的平均宽度也依次递增 （或依次递减） 。 因此狭缝电极的光透过率由边缘到中心逐渐递减 （或递增） ， 狭缝电 极的光透过率有规律地呈微小梯度的变化， 整体上狭缝电极的光透过 率不会有突然的变化， 不会影响图像的显示效果。 并且， 本发明的条 状电极的平均宽度在几微米量级， 例如， 平均宽度范围为 2〜4μιη, 条 状电极之间的宽度差值在约 0.2〜0.5μιη范围内 ,条状电极平均宽度的变 化范围约占条状电极平均宽度的十分之一， 并且条状电极的宽度范围 较宽， 平均宽度较小的条状电极相比较现有技术增加了局部光透过率， 平均宽度较大的条状电极相比较现有技术降低了局部光透过率， 整体 上同一狭缝电极单元对应的像素区域的光透过率相比较现有技术等平 均宽度的条状电极排布对应的光透过率不会有较大改变。 透过率更加均匀。
在上述任一实施方式的狭缝电极中， 所述狭缝电极单元中的各条 状电极的延伸方向相互平行， 或者相邻两个条状电极的延伸方向具有 设定夹角。
参见图 5 , 相邻两个条状电极的延伸方向具有设定夹角 α , 当狭缝 电极为公共电极 （或像素电极） 时， 不同方向排列的条状电极与像素 电极 （或公共电极） 之间的电场方向不同， 靠近不同方向排列的条状 电极的液晶分子的偏转方向不同， 可以增加液晶显示装置的视角范围， 实现广视角显示的目的。
具体地， 狭缝电极单元 1 中包括由沿第一方向延伸的第一条状电 极 31组成的第一条状电极组，和由沿第二方向延伸的第二条状电极 41 组成的第二条状电极组。
第一条状电极组中的第一条状电极 31和第二条状电极组中的第二 条状电极 41间隔排列， 保证相邻两个条状电极排列方向不同， 靠近相 邻两个条状电极的液晶分子的偏转方向不同， 进一步增加了液晶显示 装置的视角范围。
在图 5 中， 带单箭头的线段表示条状电极的延伸方向。 带 箭头 的线段表示条状电极延伸方向的夹角。 第一方向和第二方向之间的夹 角 α的范围为 3〜20。 。 例如， 第一方向和第二方向之间的夹角可以为 3〜11。 。
参见图 6 , 狭缝电极包括两个狭缝电极单元 1 , 每一狭缝电极单元
1中的各条状电极的延伸方向相互平行。所述两个狭缝电极单元 1 中的 一个中的各第一条状电极 31沿第一方向延伸， 另一个中的各第二条状 电极 41沿第二方向延伸。
在图 6 中， 带单箭头的线段表示条状电极的延伸方向。 带 箭头 的线段表示条状电极延伸方向的夹角。 第一方向和第二方向之间的夹 角为 β 。
狭缝电极中的各条状电极之间可以通过引线将各条状电极位于同 一侧的端部电连接。
所述狭缝电极可以为液晶显示面板中的公共电极和 /或像素电极。 具体实施时， 为公共电极施加直流电信号， 为像素电极施加灰阶 信号， 二者之间产生电场控制液晶分子的偏转实现图像显示。
根据本发明的一个方面提供一种阵列基板， 包括： 呈阵列分布的 亚像素单元， 亚像素单元包括： 公共电极和像素电极， 公共电极和像 素电极中的至少一个为上述狭缝电极。
阵列基板上公共电极和像素电极至少包括如下几种实施方式： 实施方式一： 参见图 7和图 8 , 图 7为根据本发明一个实施例提供 的显示装置中像素电极和公共电极的结构示意图， 图 8为图 7所示的 像素电极和公共电极在 AA方向的截面图。
衬底基板 6上的公共电极 3和像素电极 4位于不同层，公共电极 3 位于像素电极 4下方， 二者之间通过绝缘层 5相绝缘， 像素电极 4为 根据本发明的各个实施例提供的狭缝电极， 像素电极 4 包括狭缝之间 的像素条状电极 411 , 公共电极 3为面状电极。
实施方式二： 公共电极和像素电极位于不同层， 公共电极位于像 素电极上方， 二者之间通过绝缘层相绝缘， 公共电极为根据本发明的 各个实施例提供的狭缝电极， 像素电极为面状电极。
实施方式三： 参见图 9和图 10 , 图 9为公共电极 3和像素电极 4 的俯视示意图， 图 10为图 9在 BB方向的一种截面图， 其中公共电极 3和像素电极 4位于不同层， 公共电极 3位于像素电极 4下方， 二者之 间通过绝缘层 5相绝缘， 像素电极 4和公共电极 3为根据本发明的各 个实施例提供的狭缝电极。
具体地， 像素电极 4包括多个像素条状电极 41 1 , 公共电极 3包括 多个公共条状电极 311。
公共条状电极 31 1和像素条状电极 411之间可以存在交叠区域， 也可以无交叠区域， 图 9和图 10所示的公共条状电极 311和像素条状 电极 41 1之间无交叠区域。
公共条状电极 31 1和像素条状电极 411之间存在交叠区域时， 其 中一种实施方式为： 如图 1 1所示， 可以设置各公共条状电极 311相对 矩形状的像素单元的一个边缘倾斜 5° ,各像素条状电极 411相对所述 矩形状的像素单元的该边缘倾斜 13° 。 公共条状电极 31 1和像素条状 电极 41 1之间的夹角为 8° 左右。该角度保证公共条状电极 311和像素 条状电极 411 几乎平行， 不会引起液晶显示装置暗态漏光等现象。 当 公共条状电极 311 和像素条状电极 411之间的夹角过大或者公共条状 电极 31 1 和像素条状电极 41 1 与像素单元的边缘倾斜角过大时， 在相 同电场强度下， 容易出现光透过率变小、 图像的亮度不太均匀、 色偏 较大等问题。
实施方式四： 公共电极和像素电极位于不同层， 公共电极位于像 素电极上方， 二者之间通过绝缘层相绝缘， 像素电极和公共电极为根 据本发明的各个实施例提供的狭缝电极。 优选地， 公共电极和像素电 极在阵列基板上的投影无重叠区域。 实施方式三和实施方式四相比较实施方式一和实施方式二， 减少 了像素电极和公共电极之间的正对交叠面积 , 减少了二者之间的正对 电场， 从而减少了二者之间的电容， 提高了图像的显示效率， 由于公 共电极和像素电极位于不同层， 且二者均为狭缝电极， 公共电极中的 狭缝和像素电极中的狭缝会较宽， 制作公共电极和像素电极的工艺余 量会明显提高。
实施方式五：
参见图 9 ,公共电极 3和像素电极 4均为根据本发明的各个实施例 提供的狭缝电极。
参见图 12为图 9在 BB方向的第二种截面图， 其中公共电极 3和 像素电极 4同层设置。
公共电极 3 中的公共条状电极 311和像素电极 4 中的像素条状电 极 411间隔排列， 保持相互绝缘。
公共电极 3 中的公共条状电极 311和像素电极 4 中的像素条状电 极 41 1 的平均宽度可以不相等。 各个公共条状电极 311 和像素条状电 极 411的平均宽度按照排列顺序递增或递减。
根据本发明实施例提供的上述像素电极和公共电极的设置方式， 由于其公共电极和 /或像素电极为上述提供的狭缝电极， 工艺变动范围 较大， 制作狭缝电极的精度范围增大了约一倍， 工艺余量提高。 产品 在量产时更易于获得光透过率满足需求的良品， 从而实现成本的节约。
本发明的另一个方面还提供一种显示装置， 包括上述根据本发明 的各个实施例提供的阵列基板。
具体地， 显示装置包括相对设置的第一基板和第二基板， 第一基 板和第二基板中的一个为包括像素电极和公共电极的基板， 另一个为 包括黑矩阵和彩色滤光片的基板， 像素电极和公共电极中的至少一个 为根据本发明的各个实施例中任一方式提供的狭缝电极。

显示装置还可以为： 在上述两种结构的显示装置的基础上还包括： 在与像素电极和公共电极所在基板相对的基板上设置的像素电极和公 共电极。
当然， 根据本发明的各个实施例提供的显示装置仅是列举有限的 几个示例， 任何包括根据本发明的各个实施例提供的狭缝电极的显示 装置均在本发明范围之内。
根据本发明的各个实施例提供的显示装置可以为液晶显示面板、 液晶显示器、 液晶电视等显示装置。
