具体实施方式
图1为本实施例提供的一种显示面板驱动方法的流程示意图，该驱动方法可以应用在需要驱动显示面板进行平面显示的场景。该方法包括：
步骤110、进行平面显示时，通过第一扫描线控制第一开关管和第二开关管导通，通过第二扫描线控制第三开关管关断，数据线通过第一开关管和第二开关管向第一像素电极和第二像素电极输入数据信号，驱动第一像素电极和第二像素电极在像素单元中进行显示。
图2为本实施例提供的一种阵列基板的结构示意图，图3为本实施例提供的一种阵列基板的像素单元的等效电路图。结合图2和图3，阵列基板包括多条数据线11、多条第一扫描线21、多条第二扫描线22、多个像素单元30、多个第一开关管41、多个第二开关管42和多个第三开关管43。
其中，每个像素单元30包括采用相同材料制成的第一像素电极31、第二像素电极32和辅助电极33。第一开关管41和第一像素电极31对应设置，第一开关管41的控制电极A1与第一扫描线21电连接，第一电极A2与数据线11电连接，第二电极A3与对应的第一像素电极31电连接。第二开关管42与第二像素电极32对应设置，第二开关管42的控制电极B1与第一扫描线21电连接，第一电极B2与和第一开关管41电连接的数据线11电连接，第二电极B3与对应的第二像素电极32电连接。第三开关管43与辅助电极33对应设置，第三开关管43的控制电极C1与第二扫描线22电连接，第一电极C2与同一像素单元30中的第二像素电极32电连接，第二电极C3与对应的辅助电极33电连接。
通过第一扫描线21能够控制第一开关管41和第二开关管42打开，通过第二扫描线22控制第三开关管43关断，数据线11可以将数据信号输入第一像素 电极31和第二像素电极32，此时第一像素电极31和第二像素电极32在像素单元30进行显示，且第一像素电极与第二像素电极上的电压相同。
步骤120、通过第二扫描线控制第三开关管导通，通过第一扫描线控制第一开关管和第二开关管关断，通过辅助电极控制第一像素电极和第二像素电极之间形成预定电压差。
结合2和图3，可以通过第二扫描线22控制第三开关管43打开，通过第一扫描线21控制第一开关管41和第二开关管42关断，则第二像素电极32上的部分电荷可以通过第三开关管43释放至辅助电极33，第一像素电极31与第二像素电极32之间形成电压差，使得对应第一像素电极31和对应第二像素电极32设置的液晶分子的倾角出现差异，提高液晶显示面板的可视角度，降低了液晶显示面板的色偏。同时，由于辅助电极33与第一像素电极31和第二像素电极32采用相同的材料制成，示例性的，构成第一像素电极31、第二像素电极32和辅助电极33的材料可以包括氧化铟锡材料，可以解决相关技术中存在的液晶显示面板开口率降低的问题，即辅助电极33的设置在减低了液晶显示面板色偏的同时，提高了液晶显示面板的开口率。
示例性的，图4为图1所示驱动方法的时序图。结合图2、3和4，G21m、G21n和G21p分别为显示面板任意三条第一扫描线21上的扫描信号，G22m、G22n和G22p分别为与所述三条第一扫描线对应的第二扫描线22上的扫描信号。进行平面显示时，参照图4，均采用正扫的方式，即第二扫描线22上的扫描信号G22m、G22n和G22p中的高电平脉冲均延迟于第一扫描线21上扫描信号G21m、G21n和G21p中的高电平脉冲，以实现通过辅助电极33控制第一像素电极31和第二像素电极32之间形成预定电压差，解决显示面板的色偏问题。
可选的，第一开关管41可以为薄膜晶体管，则第一开关管41的控制电极A1为薄膜晶体管的栅极，第一开关管41的第一电极A2为薄膜晶体管的漏极，第一开关管41的第二电极A3为薄膜晶体管的源极。
可选地，第二开关管42也可以为薄膜晶体管，则第二开关管42的控制电极B1为薄膜晶体管的栅极，第二开关管42的第一电极B2为薄膜晶体管的漏极，第二开关管42的第二电极B3为薄膜晶体管的源极。
可选的，如图3所示，第一像素电极31、第二像素电极32和辅助电极33可以与至少一个存储电容51并联，且存储电容51位于液晶显示面板的非显示区，图3示例性地设置第一像素电极31、第二像素电极32和辅助电极33分别与一个存储电容51并联，存储电容51的设置能够有效避免第一像素电极31、第二像素电极32以及辅助电极33上电压的波动，保证第一像素电极31、第二像素电极32以及辅助电极33工作的稳定性。同时将与第一像素电极31、第二像素电极32和辅助电极33并联的电容51设置在液晶显示面板的非显示区，能够避免存储电容51对液晶显示面板开口率的影响。
图5为本实施例提供的另一种显示面板的驱动方法的流程示意图。所述驱动方法可以应用在需要驱动显示面板进行三维立体显示的场景，可以由本实施例提供的显示面板来执行。该方法包括：
步骤210、进行三维立体显示时，通过第二扫描线控制第三开关管导通，通过第一扫描线控制第一开关管和第二开关管关断，控制公共电压信号线通过第三开关管的第三电极向辅助电极输入公共电压信号。
在进行三维立体显示时，不同于平面显示，采用反扫的方式驱动液晶显示面板进行显示。图6为图5所述驱动方法的时序图，G21m’、G21n’和G21p’分别为显示面板任意三条第一扫描线21上的扫描信号，G22m’、G22n’和G22p’分别为与所述三条第一扫描线对应的第二扫描线22上的扫描信号，不同于平面显示，三维立体显示采用反扫的方式，即第二扫描线22上的扫描信号G22m、G22n和G22p中的高电平脉冲均提前于第一扫描线21上扫描信号G21m、G21n和G21p中的高电平脉冲。
示例性的，如图2所示，第一像素电极31、第二像素电极32和辅助电极33可以沿平行于数据线11的方向依次设置，第二扫描线22和第三开关管43在第二像素电极32和辅助电极33所在层上的投影可以位于第二像素电极32和辅助电极33之间。
可选的，图7为本实施例提供的一种第三开关管的结构示意图，如图7所示，第三开关管43包括控制电极C1、第一电极C2、第二电极C3和第三电极C4，阵列基板还可以包括公共电压信号线，第三电极C4可以与公共电压信号线电连 接，第三开关管43根据第二扫描线22的第二扫描信号可以控制第三开关管43的第一电极C2和第二电极C3导通，即将第二像素电极32和辅助电极33相连通，也可以控制第二电极C3与第三电极C4相连通，即将公共电压信号线和辅助电极33相连通。
液晶显示面板进行显示时，数据线11与像素电极电连接，为对应的像素电极提供数据信号，此时公共电极上为公共电压信号，液晶分子在像素电极与公共电极之间形成的电场的作用下发生偏转，实现液晶显示面板的显示功能。需要说明的是，本实施例中的液晶显示面板可以是常亮模式的液晶显示面板，也可以是常暗模式的液晶显示面板。对于常亮模式的液晶显示面板，当像素电极与公共电极之间存在电场时，液晶分子的排列方向均与所述电场方向一致，液晶分子不旋光，由于常亮模式的液晶显示面板中，液晶分子两侧偏振片的偏振光方向相互垂直，所述像素电极所在像素结构呈暗态；当像素电极与公共电极之间不存在电场时，所述像素电极所在像素结构呈亮态。对于常暗模式的液晶显示面板，液晶分子两侧偏振片的偏振光方向相互平行，则当像素电极与公共电极之间存在电场时，像素电极所在像素结构呈亮态；当像素电极与公共电极之间不存在电场时，所述像素电极所在像素结构呈暗态。本实施例对液晶显示面板是常亮模式还是常暗模式不作限定，为方便描述，下面以常暗模式的液晶显示面板为例进行说明，本领域技术人员应该理解，本实施例中提到的像素结构的亮态与暗态都是相对的。
结合图2和图3，可以先通过第二扫描线22控制第三开关管43导通，且通过第一扫描线21控制第一开关管41和第二开关管42都关断，公共电压信号线可以通过第三开关管43的第三电极C4与第二电极C3连通，辅助电极33和公共电极上均为公共电压信号，公共电极与辅助电极33之间不存在电压差，即公共电极与辅助电极33之间无法形成控制二者之间液晶分子偏转的电场，此时辅助电极33所在像素结构呈暗态。
步骤220、通过第一扫描线控制第一开关管和第二开关管导通，通过第二扫描线控制第三开关管关断，数据线通过第一开关管和第二开关管向第一像素电极和第二像素电极输入数据信号，驱动第一像素电极和第二像素电极进行显示。
参照图2和图3，可以通过第一扫描线21控制第一开关管41和第二开关管42打开，通过第二扫描线22控制第三开关管43关断，数据线11将数据信号输送至第一像素电极31和第二像素电极32，第一像素电极31和第二像素电极32与公共电极之间形成电压差，第一像素电极31与第二像素电极32所在像素结构呈亮态。如图2所示，即第一像素电极31和第二像素电极32所在像素结构亮态，辅助电极33所在像素结构呈暗态，使得沿平行于数据线11的方向，呈暗态的像素结构将呈亮态的像素结构间隔开，呈亮态的像素结构之间的距离增加，能够在进行三维立体显示时，增加液晶显示面板的视角，改善不同像素电极所在像素结构之间由于距离过近造成的串扰现象。
图8为本实施例提供的一种显示面板的驱动装置的结构示意图。如图8所示，显示面板的驱动装置包括驱动模块51和电压控制模块52，在进行平面显示时，驱动模块51设置为通过第一扫描线控制第一开关管和第二开关管导通，通过第二扫描线控制第三开关管关断，以使数据线通过第一开关管和第二开关管向第一像素电极和第二像素电极输入数据信号，以驱动第一像素电极与第二像素电极在像素单元进行显示。电压控制模块52设置为通过第二扫描线控制第三开关管导通，以及通过第一扫描线控制第一开关管和第二开关管关断，使得第二像素电极中的部分电荷转移到辅助电极中，以控制第一像素电极和第二像素电极之间形成预定电压差。
显示面板包括阵列基板，还可以包括与阵列基板相对设置的彩膜基板。阵列基板包括多条数据线、多条第一扫描线、多条第二扫描线、多个像素单元、多个第一开关管、多个第二开关管和多个第三开关管，每个像素单元包括采用相同材料制成的第一像素电极、第二像素电极和辅助电极；第一开关管与第一像素电极对应设置，第一开关管的控制电极与第一扫描线电连接，第一开关管的第一电极与一条数据线电连接，第一开关管的第二电极与对应的第一像素电极电连接；第二开关管与第二像素电极对应设置，第二开关管的控制电极与第一扫描线电连接，第二开关管的第一电极与和第一开关管电连接的数据线电连接，第二开关管的第二电极与对应的第二像素电极电连接；第三开关管与辅助电极对应设置，第三开关管的控制电极与第二扫描线电连接，第三开关管的第 一电极与同一像素单元中的第二像素电极电连接，第三开关管的第二电极与对应的辅助电极电连接。既能够通过辅助电极存储第二像素电极中的部分电荷，使第一像素电极与第二像素电极之间形成电压差，实现降低色偏的目的，且辅助电极与第一像素电极和第二像素电极可以采用相同的材料制成，避免了辅助电极对液晶显示面板开口率的影响。
可选地，进行三维立体显示时，上述电压控制模块52还设置为通过第二扫描线控制第三开关管导通，通过第一扫描线控制第一开关管和第二开关管关断，以控制公共电压信号线通过第三开关管的第三电极向辅助电极输入公共电压信号；驱动模块51还设置为通过第一扫描线控制第一开关管和第二开关管导通，通过第二扫描线控制第三开关管关断，控制数据线通过第一开关管和第二开关管向第一像素电极和第二像素电极输入数据信号，以驱动第一像素电极与第二像素电极在像素单元中进行显示。
