Description

一种液晶显示面板及装置 技术领域
本发明涉及显示器技术领域，特别是涉及一种液晶显示面板及装置。
背景技术
液晶显示器（ Liquid crystal display ， LCD ）以其轻、薄等优点成为发展最为迅速的平板显示器之一。但是与阴极射线管显示器相比，薄膜晶体管显示器（ Thin Film Transistor ， TFT-LCD ）的视角相对较窄，使其在对视角要求严格的高端显示领域的应用带来了很大局限，如航空航天、医疗等领域。
随着 LCD 领域广视角技术的迅速发展，目前很多产品的视角已经可以达到水平视角和垂直视角分别为 85 ° /85 °，甚至更大的视角。 LCD 广视角技术主要包括多畴垂直取向（ Multi-domain Vertical Alignment ）技术和面内转换（ In Plane Switching ， IPS ）技术。垂直取向模式的优点是正面对比度高，通常可以达到 4000 ： 1 及以上； IPS 技术通过在 TFT 阵列基板上形成平行且重复分布的像素电极和公共电极，使液晶分子在水平电场的作用下转动，从而形成广视角，但是其对比相对较低，通常在 2000 ： 1 以下。
现有增大视角的方式主要是使主像素和子像素的亮度不一样。如图 1 所示，现有的液晶显示面板中的每个像素包括主像素区和子像素区，主像素区包括第一薄膜晶体管 T1 、第一存储电容 Cst1 、第一液晶电容 Clc1 、第一电容 C1 以及第二电容 C2 ，子像素区包括第二薄膜晶体管 T2 、第三薄膜晶体管 T3 、第二存储电容 Cst2 以及第二液晶电容 Clc2 ，第一薄膜晶体管 T1 的栅极和第二薄膜晶体管 T2 的栅极都与扫描线 Gn 连接，第一薄膜晶体管 T1 的源极和第二薄膜晶体管 T2 的源极与数据线 Data 连接，第一存储电容 Cst1 和第一液晶电容 Clc1 的一端与第一薄膜晶体管 T1 的漏极连接，第一存储电容 Cst1 的另一端与阵列基板侧的公共电极连接，第一液晶电容 Clc1 的另一端与彩膜基板侧的公共电极连接，第一电容 C1 的一端与第一薄膜晶体管 T1 的漏极连接；第一电容 C1 的另一端与第二电容 C2 连接，第二电容 C2 的另一端与阵列基板侧的公共电极连接。
第二存储电容 Cst2 和第二液晶电容 Clc2 的一端与第二薄膜晶体管 T2 的漏极连接，第二存储电容 Cst2 的另一端与阵列基板侧的公共电极连接；第二液晶电容 Clc2 的另一端与彩膜基板侧的公共电极连接，第二薄膜晶体管 T2 的漏极连接第三薄膜晶体管 T3 的源极，第三薄膜晶体管 T3 的漏极与第一电容 C1 和第二电容 C2 之间的节点连接，第三薄膜晶体管 T3 的栅极连接扫描线 Gn+1 。
如图 2 所示， Va 和 Vb 分别表示主像素区和子像素区的电压， t1 - t2 时段，扫描线 Gn 的信号为高电平， T1 和 T2 闭合， T3 断开， Va 和 Vb 都为高电平。 t2 时刻，扫描线 Gn 关闭，扫描线 Gn+1 开启， T1 和 T2 断开， T3 闭合，第二液晶电容 Clc2 放电，对第一电容 Cl 的下基板充电，使得 Va 的电压增大，也即 Va 大于 Vb ，从而增大了视角。但是由于薄膜晶体管的数量较多，导致开口率和穿透率降低。
因此，有必要提供一种液晶显示面板及装置，以解决现有技术所存在的问题。

 本发明的最佳实施方式
以下各实施例的说明是参考附加的图式，用以例示本发明可用以实施的特定实施例。本发明所提到的方向用语，例如「上」、「下」、「前」、「后」、「左」、「右」、「内」、「外」、「侧面」等，仅是参考附加图式的方向。因此，使用的方向用语是用以说明及理解本发明，而非用以限制本发明。在图中，结构相似的单元是以相同标号表示。
请参照图 3-6 ，图 3 为本发明液晶显示面板的结构示意图。
本实施例的液晶显示面板包括：多条数据线 Dn-Dn+5 、多条扫描线 Gn-Gn+3 以及 多个像素组 10 。每个像素组 10 包括两个像素，其中这两个像素相邻设置。由多条扫描线限定的像素形成多行像素，由多条数据线限定的像素形成多列像素，每行像素对应设置一条扫描线，每列像素对应设置一条数据线。
结合图 4 ，每个像素组 10 包括第一像素 11 和第二像素 12 ；
所述第一像素 11 包括第一薄膜晶体管 T1 、第一存储电容 CST1 、第一液晶电容 CLC1 ，第一充电电容 CS1 以及第二充电电容 CS2 ；所述第一薄膜晶体管 T1 的栅极与对应的扫描线连接，所述第一薄膜晶体管 T1 的源极与对应的数据线连接；第一存储电容 CST1 和第一液晶电容 CLC1 的一端与第一薄膜晶体管 T1 的漏极连接，第一存储电容 CST1 的另一端与阵列基板侧的公共电极连接，第一液晶电容 CLC1 的另一端与彩膜基板侧的公共电极连接，所述第一充电电容 CS1 的一端与所述第一薄膜晶体管 T1 的漏极连接，所述第一充电电容 CS1 的另一端与所述第二充电电容 CS2 的一端连接；所述第二充电电容 CS2 的另一端与阵列基板侧的公共电极连接。
所述第二像素 12 包括第二薄膜晶体管 T2 、第二存储电容 CST2 和第二液晶电容 CLC2 。所述第二薄膜晶体管 T2 的栅极与对应的扫描线连接，所述第二薄膜晶体管 T2 的源极与对应的数据线连接；第二存储电容 CST2 和第二液晶电容 CLC2 的一端与第二薄膜晶体管 T2 的漏极连接，第二存储电容 CST2 的另一端与阵列基板侧的公共电极连接；第二液晶电容 CLC2 的另一端与彩膜基板侧的公共电极连接，第二薄膜晶体管 T2 的漏极还与所述第一充电电容 CS1 的另一端连接。具体地，第二薄膜晶体管 T2 的漏极与第一充电电容 CS1 和第二充电电容 CS2 之间的节点连接。
其中，第一像素 11 和第二像素 12 以行为单位进行交替设置。比如，第一行为第一像素，第二行为第二像素，第三行为第一像素，第四行为第二像素。第一像素 11 和第二像素 12 位于相邻的两行，比如当所述第一像素位于第 n 行，所述第二像素位于第 n+1 行，其中液晶显示面板包括 N 行像素， 0 ＜ n ＜ N ， N ≥ 2 。
在具体驱动过程中，如图 5 所示， t2-t3 时段， Gn 输入的扫描信号为高电平，第一薄膜晶体管 T1 闭合，使得第一像素 11 的电压 V1 等于数据电压，也即为高电平，而此时 Gn+1 输入的扫描信号为低电平，第二像素 12 的电压 V2 为低电平， t3-t4 时段， Gn+1 输入的扫描信号为高电平，第二薄膜晶体管 T2 闭合，对第二像素 12 进行充电的同时，也同时向第一充电电容 CS1 的下基板充电，从而使得 V1 进一步增大，也即 V1 大于 V2 ，从而使得第一像素 11 的亮度大于第二像素 12 的亮度，也即增大了视角。 t4 时刻之后，由于扫描线为低电平，因此 V1 和 V2 为低电平。
图 6 给出图 4 对应的显示亮度，如图 6 所示， H 表示像素的亮度或者电压较高， L 表示像素的亮度或者电压较低，由于第一像素和第二像素以行为单位交替分布，使得所有高电位的像素位于同一行，所有低电位的像素位于同一行，因此液晶显示面板的亮度从上到下为高、低、高、低。且由于这种面板的结构规整，简化液晶显示器的制程工序。本实施例的液晶显示器由于在相邻像素之间进行分压，从而增大了视角。其中每一行像素的颜色分别为红、绿、蓝、红、绿、蓝。
与图 1 的液晶显示器相比，由于每个像素只需要一个薄膜晶体管，而不是每个像素需要三个薄膜晶体管，因此减少了 TFT 的数量。且由于每两个像素需要一组 CS1 和 CS2 ，而不是每个像素需要一组 CS1 和 CS2 ，因此减少了电容的数量。由于使用较少的薄膜晶体管和电容，因此提高了开口率和穿透率。
可以理解的，第一像素 11 和第二像素 12 的位置可以互换 。
请参照图 7-8 ，图 7 为本发明液晶显示面板的第二种结构示意图
本实施例的液晶显示面板与上一实施例的区别在于， 所述第一像素 11 和所述第二像 12 素交错设置。其中在一实施方式中，所述第一像素 11 位于第 2k+1 列（奇数列）的第 n 行或者第 2k 列（偶数列）的第 n+1 行；所述第二像素位于第 2k+1 列的第 n+1 行像素或者第 2k 列的第 n 行，其中液晶显示面板包括 N 行像素， 0 ＜ n ＜ N ， N ≥ 2 ， k ≥ 0 。
如图 8 所示，由于第一像素和第二像素交错设置，使得高电位的像素和低电位的像素交错分布，也即相邻两个像素的亮度不同，在第一实施例的基础上，还可以避免水平方向出现亮暗线，提高了显示效果。
请参照图 9-10 ，图 9 为本发明液晶显示面板的第三种结构示意图
本实施例的液晶显示面板与第一实施例的区别在于， 所述液晶显示面板包括第一区域 21 和第二区域 22 。为了更好地防止水平方向出现亮暗线，在一实施方式中，所述第一区域 21 的面积和所述第二区域 22 的面积相等。在一实施方式中，第一区域和第二区域为液晶显示面板的左半部分区域和右半部分区域。在另一实施方式中，第一区域和第二区域为液晶显示面板的上半部分区域和下半部分区域。
所述第一区域 21 中的所述第一像素 11 和所述第二区域 22 中的第二像素 12 位于同一行；所述第一区域 21 中的所述第二像素 12 和所述第二区域 22 中的第一像素 11 位于同一行；
位于所述第一区域 21 中的所述第一像素 11 和位于所述第一区域 21 中的所述第二像素 12 以行为单位交替设置；位于所述第二区域 22 中的所述第一像素 11 和位于所述第二区域 22 中的所述第二像素 12 以行为单位交替设置。
具体地，当所述第一区域 21 中的所述第一像素位于第 n 行；所述第一区域 21 中的所述第二像素位于第 n+1 行。
此时所述第二区域 22 中的所述第一像素 11 位于第 n+1 行；所述第二区域 22 中的所述第二像素 12 位于第 n 行。
如图 10 所示，由于第一区域和第二区域中的第一像素和第二像素的位置不同，使得三个高电位的像素和三个低电位的像素位于同一行，即高电位的像素和低电位的像素对称分布；也即同一行中一半像素的亮度与另一半像素的亮度不同。在第一实施例的基础上，避免了水平方向出现亮暗线，且像素排列较规整，简化了生产工序。
可以理解的，该第一区域和第二区域的数量不限于一个，在另一实施例中，液晶显示面板可以包括两个第一区域和一个第二区域，此时第二区域位于两个第一区域之间，两个第一区域分别位于显示面板的两侧。在一实施方式中，两个第一区域的面积之和等于第二区域的面积。在一实施方式中，所述两个第一区域的面积也可不等于第二区域的面积。
其中两个所述第一区域中的所述第一像素和所述第二区域中的第二像素位于同一行；两个所述第一区域中的所述第二像素和所述第二区域中的第一像素位于同一行。位于所述第一区域中的所述第一像素和位于所述第一区域中的所述第二像素以行为单位交替设置；位于所述第二区域中的所述第一像素和位于所述第二区域中的所述第二像素以行为单位交替设置。
本发明实施例还提供一种液晶显示装置，其包括背光模块及上述任意一种液晶显示面板。
本发明的液晶显示面板及装置，在对下一个像素充电时继续对上一像素充电，使得相邻两个像素的亮度不同，从而增大了液晶显示面板的视角，此外还减少了薄膜晶体管和电容的数量，进而提高了开口率和穿透率。
综上所述，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。
