【具体实施方式】
下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行清楚、完整地描述，显然，本发明以下所描述的实施例仅仅是本发明的一部分实施例，而不是全部的实施例。基于本发明中的实施例，本领域普通技术人员在没有作出创造性劳动前提下所获得的所有其它实施例，都属于本发明保护的范围。
图3是本发明优选实施例的液晶显示面板的剖视图，图4是该液晶显示面板的像素结构示意图。请结合图3和图4所示，液晶显示面板30包括第一基板31、第二基板32和液晶层33，第一基板31和第二基板32相对间隔设置，液晶层33填充于两者之间，第二基板32为CF(Color Filter，彩色滤光片)彩膜基板，第一基板31为TFT(Thin Film Transistor，薄膜晶 体管)阵列基板，第一基板31包括透明基体以及设置于透明基体上的各种配线和像素电极等。具体地，
第一基板31包括多条平行间隔设置的数据线D1，D2，…，DN、沿垂直于数据线方向设置的多条扫描线G1，G2，…，GL、以及由多条扫描线G1，G2，…，GL和多条数据线D1，D2，…，DN定义的多个像素单元P1，P2，…，PX。其中，多条扫描线G1，G2，…，GL连接于栅极驱动器41，多条数据线D1，D2，…，DN连接于源极驱动器42，栅极驱动器41用于为多个像素单元P1，P2，…，PX提供扫描电压，源极驱动器42用于为多个像素单元P1，P2，…，PX提供驱动电压。
在本发明实施例中，图4所示的每一个像素单元(的像素电极)对应连接两条数据线和两条扫描线。应理解，其他实施例可设置每一个像素单元(的像素电极)对应连接两条数据线和至少一条扫描线，扫描线的数量根据像素单元的具体结构设定。
图5是图3所示液晶显示面板30中一个像素单元的结构示意图，其中虚线框所标示区域为一个像素单元的工作显示区域。鉴于按矩阵方式排列的多个像素单元P1，P2，…，PX的结构完全相同，本发明实施例以图5所示的像素单元50为代表进行描述。
请参阅图5所示，液晶显示面板30的像素单元50对应连接两条并排间隔设置的数据线51a、51b以及两条并排间隔设置的扫描线52a、52b，像素单元50沿与两条数据线51a、51b平行的轴线O对称设置，并且像素单元50包括分设于轴线O两侧且分别与两条扫描线52a、52b对应连接的两个像素电极53a、53b。
在像素单元50中，两条扫描线52a、52b分别与两条数据线51a、51b和轴线O相交处对应的端口不在同一水平线上，即：
扫描线52a与数据线51a相交处对应的端口E1，和扫描线52a与轴线O相交处对应的端口E2，不在同一水平线上；
扫描线52a与数据线51b相交处对应的端口E3，和扫描线52a与轴线O相交处对应的端口E2，不在同一水平线上；
扫描线52b与数据线51a相交处对应的端口E4，和扫描线52b与轴线O相交处对应的端口E5，不在同一水平线上；
扫描线52b与数据线51b相交处对应的端口E6，和扫描线52b与轴线O相交处对应的端口E5，不在同一水平线上。
需要说明的是，在像素单元50中，每一条扫描线与两条数据线51a、51b相交处对应的端口位于同一水平线上，即：
扫描线52a与数据线51a相交处对应的端口E1，和扫描线52a与数据线51b相交处对应的端口E3，位于同一水平线上；
扫描线52b与数据线51a相交处对应的端口E4，和扫描线52b与数据线51b相交处对应的端口E6，位于同一水平线上。
另外，两条扫描线52a、52b对应于轴线O和一条数据线之间的结构不相同，即：扫描线52a位于轴线O和数据线51a之间的部分，与扫描线52b位于轴线O和数据线51a之间的部分，结构不相同；扫描线52a位于轴线O和数据线51b之间的部分，与扫描线52b位于轴线O和数据线51b之间的部分，结构也不相同。
本实施例的像素单元50包括分设于轴线O两侧的两个像素电极53a、53b，每一像素电极包括第一区域Z1和第二区域Z2，两个像素电极53a、53b的第一区域Z1和第二区域Z2分设于两条扫描线52a、52b的两侧，且像素电极53a的第一区域Z1与扫描线52a连接，像素电极53a的第二区域Z2与扫描线52b连接，像素电极53b的第一区域Z1与扫描线52a连接，像素电极53b的第二区域Z2与扫描线52b连接。
另外，像素电极53a的第一区域Z1与像素电极53b的第一区域Z1之间设置有透光区域54，像素电极53a的第二区域Z2与像素电极53b的第二区域Z2之间也设置有透光区域54。对应地，图3所示的第二基板32上设置有与两个透光区域54相对应的黑矩阵，也就是说黑矩阵还与轴线O对应设置。
请结合图4和图5所示，本实施例的像素单元50还包括对应驱动两个像素电极53a、53b的具有不同结构的两个薄膜晶体管T1、T2，且多个像素单元P1，P2，…，PX中每一个像素单元所包括的两个薄膜晶体管T1、T2的结构沿轴线O对称。其中：
薄膜晶体管T1和薄膜晶体管T2均包括栅极、源极和漏极。薄膜晶体管T1的栅极通过过孔层55a、55b可实现分别与扫描线52a、52b的电连接， 薄膜晶体管T1的源极与对应的数据线51a电连接，薄膜晶体管T1的漏极通过过孔层55a、55b分别与像素电极53a的第一区域Z1和第二区域Z2对应电连接，且薄膜晶体管T1的漏极的一部分通过过孔层55a和设置于扫描线52a上的有源层56可实现与公共电极57的电连接；薄膜晶体管T2的栅极通过过孔层58a、58b可实现分别与扫描线52a、52b的电连接，薄膜晶体管T2的源极与对应的数据线51b电连接，薄膜晶体管T2的漏极通过过孔层58a、58b分别与像素电极53b的第一区域Z1和第二区域Z2对应电连接，且薄膜晶体管T2的漏极的一部分通过过孔层58a和设置于扫描线52a上的有源层56可实现与公共电极57的电连接。鉴于本发明实施例的主要目的在于像素单元的排列，且两个薄膜晶体管T1、T2的工作原理及过程可参阅现有技术，故此处不再赘述。
本发明实施例的主要目的是，设计液晶显示面板30的每一像素单元50包括两个像素电极53a、53b，且该两个像素电极53a、53b沿与两条数据线51a、51b平行的轴线O对称设置，可以看作是将现有技术中的一个像素单元和与其对称的另一个像素单元构成本发明实施例的一个像素单元50，从而使得每一像素单元50的扫描线52a、52b与相邻两条数据线51a、51b相交处对应的端口等高，保证多个像素单元P1，P2，…，PX之间的准确对接，提高像素单元设计的灵活性。
并且，由于每一像素单元50沿与两条数据线51a、51b平行的轴线O对称设置，本实施例也使得每一像素单元50对应的公共电极57与相邻两条数据线51a、51b相交处对应的端口H1、H2等高，保证多个像素单元P1，P2，…，PX之间的准确对接。
需要说明的是，本发明实施例相比较于现有技术的像素结构设计还能够产生其他有益效果，例如：
请结合图5和图6所示，将数据线51b设置于轴线O处即得到相当于现有技术中的一个像素单元，由于扫描线52a与数据线51a相交处对应的端口E1和扫描线52a与轴线O相交处对应的端口E2不等高，扫描线52b与数据线51a相交处对应的端口E4和扫描线52b与轴线O相交处对应的端口E5不等高，因此采用现有技术的重复排列该像素单元，相当于将扫描线52a与数据线51a相交处对应的端口E1从数据线51b的一侧沿水平线方向平移 至数据线51b的另一侧，平移后端口E1仍与端口E2不等高，将扫描线52b与数据线51a相交处对应的端口E4从数据线51b的一侧沿水平线方向平移至数据线51b的另一侧，平移后端口E4仍与端口E5不等高，因此现有技术的重复排列显然无法实现两个像素单元之间的准确对接，也就无法形成像素结构。若要准确对接，现有技术是重新设计每一像素单元的两条扫描线的结构，如图7所示，为扫描线(相当于图5所示的扫描线52a)增加一弯角区域W，使得扫描线52a与数据线51a相交处对应的端口E1下移，直至端口E1和扫描线52a与数据线51b相交处对应的端口E2等高。然而，弯角区域W会增大扫描线52a的电阻，在为扫描线52a提供正常的扫描电压时栅极驱动器41需要输出更大的电压，从而增大电能的损耗。相比较于现有技术，本发明实施例的像素结构，将轴对称的两个像素设计为一个像素单元，从而无需改变扫描线52a的任何结构，当然也就不会增大扫描线52a的电阻，因此能够节约电能。
再次说明，以上所述仅为本发明的实施例，并非因此限制本发明的专利范围，凡是利用本发明说明书及附图内容所作的等效结构或等效流程变换，例如各实施例之间技术特征的相互结合，或直接或间接运用在其他相关的技术领域，均同理包括在本发明的专利保护范围内。
