获取待充电的下一奇数列子像素单元；以及，
控制所述待充电的下一奇数列子像素单元执行充电操作。

获取所述奇数列子像素单元的有效充电时间以及总充电时间；以及，
计算所述有效充电时间与所述总充电时间之间的比值，将所述比值作为所述奇数列子像素单元的充电时间占空比。
进一步地，处理器1001可以设置于调用存储器1002中存储的显示面板的驱动程序，并执行以下操作：

步骤S30、调节所述偶数列子像素单元的充电时间占空比至所述目标充电时间占空比。
在半源驱动技术中，如图6所示，由于RC信号延迟效应，数据线上的方波数据信号实际上并非如图5所示理想的方波，而是如图6数据信号显示的在电压变换处有些弯折。当扫描线依次打开时，给像素单元依次充电，奇数列上的像素单元获得的数据信号属于起始端充电，由于在起始位置数据信号有个上升的过程，波形较差会导致亮度较暗，而偶数列上的像素单元获得的数据信号属于尾端充电，波形较佳会导致亮度较亮，所以会导致垂直亮暗线。本实施例通过调节偶数列子像素单元的充电时间占空比来避免垂直亮暗线。可以理解，本实施例中的奇数列及偶数列只是以图5或者图6所示排列方式进行命名，在其他实施例中，图5或者图6所示的奇数列及偶数列可能调换位置，本实施例只需保证尾端充电的子像素单元的充电时间占空比小于起始端充电的子像素单元的充电时间占空比即可。
具体地，根据奇数列子像素单元的充电时间占空比确定偶数列子像素单元的目标充电时间占空比，并调节偶数列子像素单元的充电时间占空比至所述目标充电时间占空比，其中，所述目标充电时间占空比小于所述奇数列子像素单元的充电时间占空比。需要说明的是，所述目标充电时间占空比是指待调节的充电时间占空比。
充电时间占空比是指在一个脉冲循环内，有效充电时间相对于总充电时间所占的比例。所述获取奇数列子像素单元的充电时间占空比的步骤包括：获取所述奇数列子像素单元的有效充电时间以及总充电时间；计算所述有效充电时间与所述总充电时间之间的比值，将所述比值作为所述奇数列子像素单元的充电时间占空比。其中，所述奇数列子像素单元的充电时间占空比为10％至90％，所述偶数列子像素单元的充电时间占空比为10％至90％。可以理解，子像素单元的充电时间（总充电时间以及有效充电时间）可通过示波器等仪器进行检测。
具体地，也可以根据奇数列子像素单元的有效充电时间确定偶数列子像素单元的目标充电时间，并调节偶数列子像素单元的有效充电时间至所述目标充电时间，其中，所述目标充电时间小于所述奇数列子像素单元的有效充电时间。
具体地，也可提前对奇数列进行充电，这样，奇数列上的像素单元获得的数据信号波形较佳，偶数列上的像素单元获得的数据信号波形也较佳，从而避免了垂直亮暗线。提前充电的时机可根据实际应用进行设置，比如在该奇数列的前一列偶数列充电时，即对该奇数列进行充电。该提前充电方式可通过设置预充电的薄膜晶体管以及预充电的工作栅线来实现，所述预充电的薄膜晶体管与预充电的工作栅线相连接。
进一步地，所述根据所述奇数列子像素单元的充电时间占空比确定偶数列子像素单元的目标充电时间占空比的步骤包括：根据所述奇数列子像素单元的充电时间占空比获取所述奇数列子像素单元的充电电量；根据所述奇数列子像素单元的充电电量确定所述目标充电时间占空比。也就是说，可根据奇数列子像素单元的充电电量确定偶数列子像素单元的目标充电电量，并根据目标充电电量确定偶数列子像素单元的目标充电有效时间，并进一步确定目标充电时间占空比。
需要说明的是，以上实施例以2列反转的驱动方式进行说明，其它驱动方式也可适用于本实施例。比如1+2列反转的驱动方式，那么将其中的1列作为奇数列，将另外相邻的2列作为偶数列。
本实施例公开的技术方案中，根据奇数列子像素单元的充电时间占空比确定偶数列子像素单元的目标充电时间占空比，并调节偶数列子像素单元的充电时间占空比至目标充电时间占空比，其中，所述目标充电时间占空比小于所述奇数列子像素单元的充电时间占空比。这样，解决了显示画面出现垂直亮暗线的问题。
在一实施例中，在上述实施例中的基础上，所述显示装置包括数据线、扫描线以及子像素单元，所述数据线沿列方向排列，左右相邻的子像素单元共用一条数据线，所述扫描线沿行方向排列，同一行相邻的子像素单元连接不同的扫描线，同一行彼此间隔一个子像素单元的子像素单元连接相同的扫描线，所述显示面板的驱动方法还包括：
所述扫描线与扫描驱动电路连接，所述数据线与数据驱动电路连接，所述扫描驱动电路和所述数据驱动电路以两个扫描脉冲、数据信号极性反转一次的方式驱动所述子像素单元。
本实施例中，显示装置包括扫描线、数据线以及子像素单元，其中所述扫描线沿行方向排列，所述数据线沿列方向排列。所述子像素单元由所述扫描线和所述数据线交错形成。如图3所示，G代表扫描线，D代表数据线，R、G、B分别作为子像素单元，并且R、G、B组合构成像素单元。同一行相邻的子像素单元连接不同的扫描线，同一行彼此间隔一个子像素单元的子像素单元连接相同的扫描线；相邻的至少两列子像素单元共用同一条数据线。
在驱动顺序方面，由上往下进行通过扫描线进行扫描。扫描线施加高电压给与其连接的像素单元的晶体管，此时晶体管开启，并接收与其连接的数据线传入的数据信号。以同一行的像素单元来说，数据线一侧的奇数列像素单元会先被驱动，数据线另一侧的偶数列像素单元而后被驱动。如图4所示，扫描到扫描线G1时，像素单元P11、
P13分别接收数据线D1、D2传入的数据信号；扫描到扫描线G2时，像素单元P12、P14分别接收数据线D1、D2传入的数据信号。
本实施例的半源极驱动显示装置包括沿行方向排列的扫描线、沿列方向排列的数据线、由扫描线和数据线交错形成的像素单元，还包括与扫描线电连接的扫描驱动电路以及与数据线电连接的数据驱动电路。扫描驱动电路具有与扫描线电连接的多个扫描线接点，数据驱动电路具有与数据线电连接的多个数据线接点。扫描驱动电路通过扫描线接点将扫描信号输出给扫描线，数据驱动电路通过数据线接点将数据信号输出给数据线。
本实施例可采用两个扫描脉冲、数据信号极性反转一次的驱动方式。在驱动过程中，扫描驱动电路是依据扫描线接点的排列顺序进行扫描(亦即，依据扫描线接点的排列顺序依序给出扫描信号)。以同一行的像素单元来说，前一半数目的扫描线在驱动过程中，数据线一侧的奇数列像素单元会先被驱动，数据线另一侧的偶数列像素单元而后被驱动。
本实施例公开的技术方案中，所述扫描驱动电路和所述数据驱动电路以两个扫描脉冲、数据信号极性反转一次的方式驱动所述子像素单元，这样，保证显示装置的显示效果。
