进一步地，在第n+2个扫描周期内，通过扫描线Gn+2输出的扫描信号扫描第i+2行子像素12，该多路复用开关20依次接收该第一、第二、第三、第四控制信号。
具体地，首先，第一、第五薄膜晶体管T1、T5导通，该第x、第x+1数据线Sx、Sx+1分别提供高电平的数据信号给第i+2行第x列、第i+2行第x+1列像素单元11中的红色子像素R；然后，第二、第六薄膜晶体管T1、T2导通，该第x、第x+1数据线Sx、Sx+1分别提供高电平的数据信号给第i+2行第x+1列、第i+2行第x列像素单元11中的蓝色子像素B；其次，第三、第七薄膜晶体管T3、T7导通，该第x、第x+1数据线Sx、Sx+1分别提供高电平的数据信号给第i+2行第x+1列、第i+2行第x列像素单元11中的绿色子像素G；最后，第四、第八薄膜晶体管T4、T8导通，该第x、第x+1数据线Sx、Sx+1分别提供低电平的数据信号给第i+2行第x列、第i+2行第x+1列像素单元11中的白色子像素。
更进一步地，在第n+3个扫描周期内，通过扫描线Gn+3输出的扫描信号 扫描第i+3行子像素12，该多路复用开关20依次接收第二、第一、第三、第四控制信号。
具体地，首先，第二、第六薄膜晶体管T2、T6导通，该第x、第x+1数据线Sx、Sx+1分别提供低电平的数据信号给第i+3行第x+1列、第i+3行第x列像素单元11中的白色子像素W；然后，第一、第五薄膜晶体管T1、T5导通，该第x、第x+1数据线Sx、Sx+1分别提供高电平的数据信号给第i+3行第x列、第i+3行第x+1列像素单元11中的绿色子像素G；其次，第三、第七薄膜晶体管T1、T5导通，该第x、第x+1数据线Sx、Sx+1分别提供高电平的数据信号给第i+3行第x+1列、第i+3行第x列像素单元11中的蓝色子像素B；最后，第四、第八薄膜晶体管T4、T8导通，该第x、第x+1数据线Sx、Sx+1分别提供高电平的数据信号给第i+3行第x列、第i+3行第x+1列像素单元11中的红色子像素R。
需要说明的是，在图3中，第i+4行像素单元11对应的显示时序图与第i行像素单元11对应的显示时序图相同，从而，其他扫描周期内显示面板的驱动方法请参考上述对应扫描周期内显示面板的驱动方法。
当该像素模块10中的各白色子像素W接收低电平的数据信号，各红色子像素R、各绿色子像素G、各蓝色子像素B接收高电平的数据信号时，如果使用如图3所示的显示时序图调整控制信号的输入顺序，则该第x、第x+1数据线Sx、Sx+1提供的数据信号在每两个扫描周期内仅需要进行一次电平变换，而在该多路复用开关20在每一扫描周期内均依次接收该第一、第二、第三、第四控制信号的实施方式中，该第x、第x+1数据线Sx、Sx+1提供的数据信号在每两个扫描周期内需要进行三次电平变换。因此，本发明实施例的显示面板驱动方法降低了数据信号进行电平变换的频率，从而降低了显示面板的功耗。
在本发明的另一个具体实施例中，扫描信号还可以采用隔行扫描的方式扫描该像素模块10。以下结合图1、图2和图4对本发明实施例的显示面板驱动方法进行描述。

从而，在本发明的一个实施例中，第j行第x列像素单元11中的白色子像素W、绿色子像素G、蓝色子像素B、红色子像素R依次分别接收低电平、高电平、高电平、高电平的数据信号。即该第二顺序可以为白色、绿色、蓝色、红色。其中，j＝i+2。
进一步地，在第n+2个扫描周期内，通过扫描线Gn+1输出的扫描信号扫描第i+1行子像素12，该多路复用开关20依次接收该第一、第三、第四、第二控制信号。
具体地，首先，第一、第五薄膜晶体管T1、T5导通，该第x、第x+1数据线Sx、Sx+1分别提供高电平的数据信号给第i+1行第x列、第i+1行第x+1列像素单元11中的绿色子像素G；然后，第三、第七薄膜晶体管T3、T7导通，该第x、第x+1数据线Sx、Sx+1分别提供高电平的数据信号给第i+1行第x+1列、第i+1行第x列像素单元11中的红色子像素R；其次，第四、第 八薄膜晶体管T4、T8导通，该第x、第x+1数据线Sx、Sx+1分别提供高电平的数据信号给第i+1行第x列、第i+1行第x+1列像素单元11中的蓝色子像素B；最后，第二、第六薄膜晶体管T2、T6导通，该第x、第x+1数据线Sx、Sx+1分别提供低电平的数据信号给第i+1行第x+1列、第i+1行第x列像素单元11中的白色子像素W。
更进一步地，在第n+3个扫描周期内，通过扫描线Gn+3输出的扫描信号扫描第i+3行子像素12，该多路复用开关20依次接收第二、第三、第四、第一控制信号。
具体地，首先，第二、第六薄膜晶体管T2、T6导通，该第x、第x+1数据线Sx、Sx+1分别提供低电平的数据信号给第i+3行第x+1列、第i+3行第x列像素单元11中的白色子像素W；然后，第三、第七薄膜晶体管T3、T7导通，该第x、第x+1数据线Sx、Sx+1分别提供高电平的数据信号给第i+3行第x+1列、第i+3行第x列像素单元11中的蓝色子像素B；其次，第四、第八薄膜晶体管T4、T8导通，该第x、第x+1数据线Sx、Sx+1分别提供高电平的数据信号给第i+3行第x列、第i+3行第x+1列像素单元11中的红色子像素R；最后，第一、第五薄膜晶体管T1、T5导通，该第x、第x+1数据线Sx、Sx+1分别提供高电平的数据信号给第i+3行第x列、第i+3行第x+1列像素单元11中的绿色子像素G。
需要说明的是，在图4中，第i+4行像素单元11对应的显示时序图与第i行像素单元11对应的显示时序图相同，从而，其他扫描周期内显示面板的驱动方法请参考上述对应扫描周期内显示面板的驱动方法。
当该像素模块10中的各白色子像素W接收低电平的数据信号，各红色子像素R、各绿色子像素G、各蓝色子像素B接收高电平的数据信号时，如果使用如图4所示的显示时序图调整控制信号的输入顺序，则该第x、第x+1数据线Sx、Sx+1提供的数据信号在每两个扫描周期内仅需要进行一次电平变换，且在相邻两个扫描周期中，前一个扫描周期最后导通的薄膜晶体管与后一个扫描周期首先导通的薄膜晶体管相同，与该多路复用开关20在每一扫描周期内均依次接收该第一、第二、第三、第四控制信号的实施方式相比，本发明实施例额显示面板驱动方法不仅降低了数据线进行电平变换的频率，还降低了薄膜 晶体管进行状态切换的频率(即在导通和关断之间进行切换的频率)，从而很大限度地降低了显示面板的功耗。
在本说明书的描述中，参考术语“一个实施例”、“一些实施例”、“示例”、“具体示例”或“一些示例”等的描述意指结合该实施例或示例描述的具体特征、结构、材料或者特点包含于本发明的至少一个实施例或示例中。在本说明书中，对上述术语的示意性表述不一定指的是相同的实施例或示例。而且，描述的具体特征、结构、材料或特点可以在任何的一个或多个实施例或示例中以合适的方式结合。
