Description

一种阵列基板和液晶显示面板
技术领域
本发明涉及液晶显示技术领域，具体地说，涉及一种阵列基板和液晶显示面板。
背景技术
在液晶显示面板中，公共电极信号(即VCOM信号)起着十分重要的作用。对于液晶显示面板而言，面板是否工作在最佳的VCOM信号下，将直接影响面板的显示品质。当液晶显示面板没有工作在其最佳的VCOM信号的情况下，面板的显示亮度以及画面表现都将会受到影响。当液晶显示面板中所施加的VCOM信号与最佳VCOM信号偏差较大时，很可能会使得敏感的用户感觉到液晶显示面板的显示画面存在闪烁的问题，甚至使得用户产生眩晕的感觉。此外，当液晶显示面板中所施加的VCOM信号与最佳VCOM信号偏差较大时，还有可能导致液晶显示面板出现直流残留的问题。
因此，每一片液晶显示面板在出厂之前，都会进行VCOM信号的调整，以使得液晶显示面板工作在其最佳的VCOM信号下。而这种对于VCOM信号的调整通常是由工作人员手动调整或者由机台自动调整的，而这也就会导致人员成本提高、机台成本的提高以及产能损失等问题，并最终导致液晶显示面板的生产成本提高，从而降低产品竞争力。
发明内容
本发明所要解决的技术问题是为了使得阵列基板中的公共电极电压能够有效地保持在最佳的VCOM信号附近。为了解决该问题，本发明首先在一个实施例中提供了一种阵列基板，所述阵列基板包括多条扫描线和多条数据线，所述多条扫描线和多条数据线交错形成多个像素区，在各个像素区中形成有像素电极，所述像素电极通过薄膜晶体管T1与相应的扫描线和数据线连接，其中，
所述阵列基板还包括公共电极，所述公共电极包括多条公共电极线，所述公共电极线通过薄膜晶体管T2分别与第一像素电极和第二像素电极连接，其中，所述第一像素电极与第二像素电极中信号的极性相反；
所述公共电极线通过薄膜晶体管T2分别与第一像素电极和第二像素电极连接，具体为：所述薄膜晶体管T2包括第一薄膜晶体管和第二薄膜晶体管，所述公共电极线分别通过第一薄膜晶体管和第二薄膜晶体管与第一像素电极和第二像素电极连接，其中，所述第一薄膜晶体管的栅极和源极分别与第一扫描线和第一像素电极连接，所述第二薄膜晶体管的栅极和源极分别与第一扫描线和第二像素电极连接，所述第一薄膜晶体管和第二薄膜晶体管的漏极均与所述公共电极线连接；
所述像素电极通过薄膜晶体管T1与相应的扫描线连接，具体为：所述第一像素电极和第二像素电极分别通过相应的薄膜晶体管T1与第二扫描线和第三扫描线连接。
根据本发明的一个实施例，所述第一像素电极与第二像素电极为相邻像素电极行或相邻像素电极列中的两个像素电极。
根据本发明的一个实施例，
所述公共电极线通过薄膜晶体管T2与第一像素电极所处像素电极行中的多个像素电极连接，所述公共电极线还通过薄膜晶体管T2与第二像素电极所处像素电极行中的多个像素电极连接；或，
所述公共电极线通过薄膜晶体管T2与第一像素电极所处像素电极列中的多个像素电极连接，所述公共电极线还通过薄膜晶体管T2与第二像素电极所处像素电极列中的多个像素电极连接。
根据本发明的一个实施例，所述多条公共电极线沿数据线方向并排排列，或所述多条公共电极线沿扫描线方向并排排列。
根据本发明的一个实施例，所述多条公共电极线包括多条行公共电极线和多条列公共电极线，其中，所述多条行公共电极线沿扫描线的方向并排排列，所述多条列公共电极线沿数据线的方面并排排列。
根据本发明的一个实施例，所述阵列基板还包括信号输出端口，其与所述公共电极连接，用于将所述公共电极上的信号向外传输。
本发明还提供了一种液晶显示面板，其特征在于，所述液晶显示面板包括如上任一项所述的阵列基板。
根据本发明的一个实施例，所述液晶显示面板还包括彩色滤光片，所述彩色滤光片中含有公共电极，所述彩色滤光片中的公共电极与所述阵列基板中的公共电极连接。
本发明所提供的阵列基板以及液晶显示面板中公共电极的电压并不需要通过额外配置相应的供电电路来提供，而是可以通过阵列基板自身的像素电极来提供。
同时，该阵列基板的公共电极所得到的公共电极电压能够稳定在像素电极的正电压和负电压(相对于公共电极)的中间态(即保持在最佳的VCOM信号附近)，并且在需要时还可以将所得到的电压通过相应的输出端口传递到对侧面板(例如彩色滤光片)的公共电极。
相较于现有的阵列基板，本发明所提供的阵列基板实现了公共电极电压的自动调节，这样也就不需要相应的调节人员或机台，有助于提高阵列基板以及液晶显示面板的产能和产品竞争力。
本发明的其它特征和优点将在随后的说明书中阐述，并且，部分地从说明书中变得显而易见，或者通过实施本发明而了解。本发明的目的和其他优点可通过在说明书、权利要求书以及附图中所特别指出的结构来实现和获得。

具体实施方式
以下将结合附图及实施例来详细说明本发明的实施方式，借此对本发明如何应用技术手段来解决技术问题，并达成技术效果的实现过程能充分理解并据以实施。需要说明的是，只要不构成冲突，本发明中的各个实施例以及各实施例中的各个特征可以相互结合，所形成的技术方案均在本发明的保护范围之内。
同时，在以下说明中，出于解释的目的而阐述了许多具体细节，以提供对本发明实施例的彻底理解。然而，对本领域的技术人员来说显而易见的是，本发明可以不用这里的具体细节或者所描述的特定方式来实施。
图1示出了现有的液晶显示面板中阵列基板的结构示意图。
如图1所示，现有的阵列基板包括有多条数据线(即Data Line)和多条扫描线(即Gate Line)。这些数据线和扫描线交错形成多个像素区，各个像素区中形成有像素电极101。各个像素电极101通过相应的薄膜晶体管102连接到相应的扫描线和数据线。具体地，像素电极101与对应的薄膜晶体管102的漏极连接，薄膜晶体管102的栅极和源极分别与相应的扫描线和数据线连接。
需要说明的是，图1所示的阵列基板的结构示意图中，扫描线、数据线以及像素电极的示意方式并不说明扫描线、数据线以及像素电极等构件处于同一材料层中。
在液晶显示面板的驱动方式中，存在着行反转等驱动方式。如图1所示，在行反转驱动方式中，在沿数据线(即Data Line)方向上的像素电极的极性(相对于公共电极)呈现正、负、正、负交替或负、正、负、正交替地分布方式并且正负极性基本平衡。
本发明所提供的液晶显示面板便是基于液晶显示面板的上述驱动特点，来利用像素电极的不同极性来得到稳定在正负电极电压中间态的公共电极电压VCOM。
图2示出了本实施例所提供的阵列基板的结构示意图。其中，该阵列基板为UV2A型液晶显示面板中的阵列基板，其驱动方式为行反转驱动。如图2所示，本实施例所提供的阵列基板在图1所示的阵列基板的基础上增加了公共电极。其中，公共电极通过薄膜晶体管与像素电极连接。
以图2所示的部分阵列基板结构为例，第N-1条扫描线到第N+2条扫描线共4条扫描线，与第M-1条数据线到第M+2条数据线共4条数据线，交错形成了多个像素区，每个像素区中均形成有像素电极，各个像素电极通过薄膜晶体管与对应的扫描线和数据线连接。例如，作为第一像素电极的像素电极PM+2,N通过薄膜晶体管T1M+2,N与第N条扫描线和第M+2条数据线连接，作为第二像素电极的像素电极PM+2,N+1通过薄膜晶体管T1M+2,N+1与第N+1条扫描线和第M+2条数据线连接。
本实施例中，公共电极包括多条公共电极线，各条公共电极线沿数据线方向并排排列(即公共电极线的方向与数据线的方向大致相同)并通过对应的薄膜晶体管T2与相应的像素电极连接。具体地，如图2所示，第M+2条公共电极线与第一薄膜晶体管T2M+2,N的漏极连接，像素电极PM+2,N与第一薄膜晶体管T2M+2,N的源极连接，第一薄膜晶体管T2M+2,N的栅极与第N-1条扫描线连接。
同时，第M+2条公共电极线还与第二薄膜晶体管T2M+2,N+1的漏极连接，第二像素电极PM+2,N+1与第二薄膜晶体管T2M+2,N+1的源极连接，第二薄膜晶体管T2M+2,N+1的栅极与第N-1条扫描线连接。
类似地，第M+2条公共电极线还通过相应的薄膜晶体管与第M+2条数据线所对应的其他像素电极连接，其他公共电极线也采用相同的方式与对应的像素电极连接。
当第N-1条扫描线(即Gate(N-1))呈现高电位时，由于第一薄膜晶体管T2M+2,N和第二薄膜晶体管T2M+2,N+1的栅极均与第N-1条扫描线链接，因此此时第一薄膜晶体管T2M+2,N和第二薄膜晶体管T2M+2,N+1处于导通状态，从而将像素电极PM+2,N和像素电极PM+2,N+1上所存储的上一帧的电位传递给第M+2条公共电极线。同理，第N条扫描线和第N+1条扫描线对应的各个像素电极均会通过对应的薄膜晶体管将存储的电位传到给相应的公共电极线。
由于本实施例所提供的阵列基板是以行反转的方式驱动的，而第N条扫描线和第N+1条扫描线是相邻的两条扫描线，因此这两条扫描线所对应的像素电极上的电位的极性(相对于公共电极)是相反的。由于公共电极线是相连接的，因此公共电极上所呈现的电压将稳定在像素电极的正电压和负电压的中间态，由此便得到了所需要的公共电极电压。
本实施例中所提供的阵列基板为应用于UV2A型液晶显示面板中的阵列基板，而UV2A型液晶显示面板的彩色滤光片中也同样含有公共电极。因此，也就可以将彩色滤光片中的公共电极与阵列基板中的公共电极的信号输出端口连接，来使得彩色滤光片中的公共电极的电位同样稳定在像素电极的正电压和负电压(相对于公共电极)的中间态。
当然，在本发明的其他实施例中，公共电极并不一定需要通过薄膜晶体管与所有的像素电极连接。例如在本发明的一个实施例中，公共电极可以仅与第M+2条数据线所对应的全部或部分像素电极连接。
需要说明的，在本发明的其他实施例中，公共电极线还可以采用其他合理的排列方式，本发明不限于此。例如在本发明的不同实施例中，公共电极线既可以采用如图3所示的沿扫描线方向并排排列的方式，还可以采用如图4所示的部分公共电极线(即行公共电极线)沿扫描线方向并排排列、部分公共电极线(即列公共电极线)沿数据线方向并排排列的方式。
此外，还需要说明的是，当阵列基板采用其他驱动方式时，基于本实施例所提供的思想，公共电极线也可以采用与之对应的结构形式，本发明同样不限于此。例如在本发明的一个实施例中，阵列基板采用列反转的驱动方式，在该阵列基板中，公共电极的结构形式可以采用本实施例所提供的形式。而在本发明的另一个实施例中，阵列基板采用两点反转(2-line Inversion)的驱动方式时，阵列基板则可以采用如图5所示的结构。
此外，还需要说明的是，在本发明的其他实施例中，液晶显示面板还以为其他合理类型的面板(例如MVA、PVA等VA型液晶显示面板)，本发明同样不限于此。
需要指出的是，在本发明的其他实施例中，如果液晶显示面板为FFS型，其阵列基板则可以采用如图6～图8所示的结构，这些阵列基板的结构以及实现公共电极电压的自动调节的原理与上述UV2A型液晶显示面板中阵列基板的类似，在此不再赘述。需要指出的是，由于这类阵列基板的对板中并不含有公共电极，因此这类阵列基板中的公共电极也就不需要将其上的信号输出到对板中。因此，在这类液晶显示面板的阵列基板中，公共电极也就不需要配置用于将公共电极电压输出给对板的信号输出端口。
从上述描述中可以看出，本实施例所提供的阵列基板以及液晶显示面板中公共电极的电压并不需要通过额外配置相应的供电电路来提供，而是可以通过阵列基板自身的像素电极来提供。
同时，所得到的公共电极电压能够稳定在像素电极的正电压和负电压(相对于公共电极)的中间态，并且在需要时还可以将所得到的电压通过相应的输出端口传递到对侧面板(例如彩色滤光片)的公共电极。
相较于现有的阵列基板，本实施例所提供的阵列基板实现了公共电极电压的自动调节，这样也就不需要相应的调节人员或机台，有助于提高阵列基板以及液晶显示面板的产能和产品竞争力。
应该理解的是，本发明所公开的实施例不限于这里所公开的特定结构、处理步骤或材料，而应当延伸到相关领域的普通技术人员所理解的这些特征的等同替代。还应当理解的是，在此使用的术语仅用于描述特定实施例的目的，而并不意味着限制。
说明书中提到的“一个实施例”或“实施例”意指结合实施例描述的特定特征、结构或特性包括在本发明的至少一个实施例中。因此，说明书通篇各个地方出现的短语“一个实施例”或“实施例”并不一定均指同一个实施例。
为了方便，在此使用的结构单元和/或组成单元可出现在共同列表中。然而，这些列表应解释为该列表中的每个元素分别识别为单独唯一的成员。因此，在没有反面说明的情况下，该列表中没有一个成员可仅基于它们出现在共同列表中便被解释为相同列表的任何其它成员的实际等同物。另外，在此还可以连同针对各元件的替代一起来参照本发明的各种实施例和示例。应当理解的是，这些实施例、示例和替代并不解释为彼此的等同物，而被认为是本发明的单独自主的代表。
此外，所描述的特征、结构或特性可以任何其他合适的方式结合到一个或多个实施例中。在其它示例中，周知的结构并未详细示出或描述以免模糊本发明的各个方面。
虽然上述示例用于说明本发明在一个或多个应用中的原理，但对于本领域的技术人员来说，在不背离本发明的原理和思想的情况下，明显可以在形式上、用法及实施的细节上作各种修改而不用付出创造性劳动。因此，本发明由所附的权利要求书来限定。
