【背景技术】
现有技术中，薄膜晶体管-液晶显示装置（Thin Film Transistor-Liquid Crystal Display，TFT-LCD）主要包括扫描驱动器、数据驱动器及显示面板。其中，扫描驱动器将扫描驱动电压通过扫描线传输至显示面板中的像素单元，数据驱动器将数据驱动电压传输至显示面板中的像素单元。通过上述方式，像素单元在扫描驱动器和数据驱动器的控制下充电并产生电场，进而利用加在液晶分子上的电场强度变化来改变液晶分子的取向，通过控制液晶分子的偏转角度来使显示面板显示画面。
然而现有技术的液晶显示装置中，由于扫描驱动电压在传输至显示面板的像素单元的过程中因传递线路的阻抗而发生衰减，因此使得到达不同像素单元的扫描驱动电压存在电压差，从而导致显示面板的各个显示区域之间存在分界线，即产生显示画面亮度不均的现象，影响显示画面的显示品质。
因此，有必要提供一种显示面板及其驱动方法、显示装置，以解决上述问题。

【附图说明】
图1是本发明显示面板一实施例的结构示意图；
图2是图1所示阵列基板的结构示意图；
图3是图1所示彩色滤光片基板的结构示意图；
图4是本发明显示面板的驱动方法一实施例的流程图。
【具体实施方式】
下面结合附图和实施例对本发明进行详细说明。
图1是本发明显示面板一实施例的结构示意图。如图1所示，本实施例的显示面板包括：相对设置的阵列基板110和彩色滤光片基板120，以及夹持于两者之间的液晶层130。
图2是图1所示阵列基板110的结构示意图。参阅图2，阵列基板110包括：沿第一方向Y彼此间隔设置的扫描线g1、g2、g3…gn，沿第二方向X彼此间隔设置且与扫描线g1、g2、g3…gn绝缘交叉的数据线d1…dm，扫描驱动器G1、G2、G3…Gn，数据驱动器D1…Dm，以及以阵列方式设置且由扫描线g1、g2、g3…gn和对应的数据线d1…dn驱动的m*n个像素单元P11、P21、P31、Pn1…、P1m、P2m、P3m、Pnm，其中m和n的取值均为正整数。
在本实施例中，第一方向Y优选为垂直方向，第二方向X优选为水平方向。每一扫描驱动器分别对应连接一条扫描线，以在对应连接的扫描线上施加扫描驱动电压，并且每一扫描驱动器连接的扫描线所驱动的像素单元即为一显示区域。具体而言，扫描驱动器G1与扫描线g1对应连接，扫描驱动器G2与扫描线g2对应连接，扫描驱动器G3与扫描线g3对应连接，扫描驱动器Gn与扫描线gn对应连接；扫描线g1与显示区域S1相对应，扫描线g2与显示区域S2相对应，扫描线g3与显示区域S3相对应，扫描线gn与显示区域Sn相对应。
每一数据驱动器分别对应连接一条数据线，以在对应连接的数据线上施加数据驱动电压。具体而言，数据驱动器D1与数据线d1对应连接，数据驱动器Dm与数据线dm对应连接。
应理解，在其他实施例中，也可设置每一扫描驱动器分别对应连接两条或两条以上的扫描线，每一数据驱动器分别对应连接两条或两条以上的数据线。
图3是图1所示彩色滤光片基板120的结构示意图。参阅图3，彩色滤光片基板120包括沿第一方向Y彼此间隔设置的公共电极K1、K2、K3…Kn，且分别与阵列基板110上的显示区域S1、S2、S3…Sn对应设置。具体而言，公共电极K1与显示区域S1对应设置，公共电极K2与显示区域S2对应设置，公共电极K3与显示区域S3对应设置，公共电极Kn与显示区域Sn对应设置。
尤为注意的是，本实施例的公共电极K1、K2、K3…Kn是相互独立的，并且在工作时可分别独立施加公共电压。另外，任意相邻两个公共电极的间距小于或等于扫描线的宽度，以使得在对其施加公共电压时，公共电极产生的电场能够完全控制对应显示区域的液晶层中液晶分子的偏转。
下面结合图1~3详细介绍本实施例的显示面板的显示原理：
显示面板接通外部电压后通过内部的时序控制器产生第一控制信号，依次驱动扫描驱动器G1、G2、G3…Gn，以在对应连接的扫描线g1、g2、g3…gn上施加扫描驱动电压，以及依次驱动数据驱动器D1…Dm，以在对应连接的数据线d1…dm上施加数据驱动电压，进而传输至对应的像素单元P11、P21、P31、Pn1…、P1m、P2m、P3m、Pnm，像素单元P11、P21、P31、Pn1…、P1m、P2m、P3m、Pnm接收扫描驱动电压和数据驱动电压并产生电场，以此使得液晶层130中的液晶分子发生偏转，此时各个显示区域S1、S2、S3…Sn的显示画面存在一定程度的亮度差异。
而后，显示面板通过内部的时序控制器产生第二控制信号，依次在驱动的显示区域S1、S2、S3…Sn所对应的公共电极K1、K2、K3…Kn上独立施加公共电压，从而使得液晶层130中的液晶分子再次在公共电极K1、K2、K3…Kn产生的电场下发生偏转，通过调整对每一公共电极施加的公共电压的大小，从而使得液晶层130中的液晶分子偏转角度一致，消除各个显示区域S1、S2、S3…Sn显示画面的亮度差异。例如：若显示区域S1的亮度大于显示区域S2的、显示区域S2的亮度大于显示区域S3的，则可以下调施加给公共电极K1的公共电压，使得显示区域S1变暗，同时上调施加给公共电极K2、K3的公共电压，使得显示区域S2、S3不同程度的变亮，从而使得显示区域S1、S2、S3的亮度一致，消除亮度分界线，提高显示品质。
需要说明的是，由于每个显示区域的亮度不同，因此对公共电极K1、K2、K3…Kn所施加的公共电压彼此不同。
本发明还提供了一种显示装置，由于其采用上述实施例的显示面板，因此该显示装置在显示时能够消除显示画面亮度不均的现象，具有良好的显示品质。
图4是本发明显示面板的驱动方法一实施例的流程图。本实施例的驱动方法是基于图1所示实施例的显示面板进行的，主要包括以下步骤：
步骤S410：依次驱动显示区域。
具体而言，依次驱动显示面板中的扫描驱动器，以在对应连接的扫描线上施加扫描驱动电压，依次驱动显示面板中的数据驱动器，以在对应连接的数据线上施加数据驱动电压。
步骤S420：依次在驱动的显示区域所对应的公共电极上独立施加公共电压。其中，对各个公共电极所施加的公共电压彼此不同。
本实施例的驱动方法由于基于上述实施例的显示面板，具体的驱动过程可参见上述显示面板的显示原理，此处不再赘述。本实施例的驱动方法能够消除显示画面亮度不均的现象，提高显示品质。
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，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。
