具体实施方式
为了进一步说明本公开实施例提供的显示亮度补偿方法、补偿电路、显示装置，下面结合说明书附图进行详细描述。
相关技术中3T1C架构的像素电路如图1所示，其对应的工作时序如图2所示。具体工作过程如下：
在数据写入阶段P1，扫描信号G1控制第一晶体管T1导通，扫描信号G2控制第二晶体管T2导通，向第三晶体管T3的栅极(G点)写入数据信号DATA。
在发光阶段P2，扫描信号G1控制第一晶体管T1截止，扫描信号G2控制第二晶体管T2截止，第三晶体管T3的栅极电位通过存储电容Cst发生自举，第三晶体管导通，控制发光元件OLED发光直至下一个数据写入阶段。
需要说明，图1中还示意了正电源信号ELVDD，负电源信号ELVSS，感测信号SENSE，第三晶体管T3的源极如S点。图2中还示意了显示装置中其他部分应用的基准电压信号VREF的时序。
采用上述像素电路驱动显示装置显示动态显示画面时，在动态显示画面的切换过程中，容易产生动态图像拖影现象。为了解决这个问题，本公开在像素电路发光期间设置了一个画面切黑的过程，如图3所示，加入插黑功能的时序后像素电路的具体工作过程如下：
在数据写入阶段P1，扫描信号G1控制第一晶体管T1导通，扫描信号G2控制第二晶体管T2导通，向第三晶体管T3的栅极(G点)写入数据信号DATA。
在正常显示阶段P21，扫描信号G1控制第一晶体管T1截止，扫描信号G2控制第二晶体管T2截止，第三晶体管T3的栅极电位通过存储电容Cst发生自举，第三晶体管导通，控制像素正常显示。
在插黑显示阶段，在P221阶段，扫描信号G1控制第一晶体管T1导通，向第三晶体管T3的栅极(G点)写入插黑数据；在P222阶段，像素停止发 光被切为黑画面。
需要说明，可以在像素发光的某一时刻控制第一晶体管T1导通，使第三晶体管T3的栅极电位变为0，像素即被切黑停止发光，进行插黑显示。或者，在P221阶段，扫描信号G1控制第一晶体管T1导通，扫描信号G2控制第二晶体管T2导通，使第三晶体管T3具有很低的栅源电压Vgs，像素即被切黑停止发光，进行插黑显示。
但是在插黑过程中，因为正常显示和插黑显示的不同步，使得有一部分子像素行能够在同一帧显示时段内进行正常显示和插黑显示，如图4所示的1～12行子像素行，其他子像素行都是当前帧显示时段进行正常显示，相邻的下一帧显示时段进行插黑显示。由于当前帧显示时段和相邻的下一帧显示时段之间还具有第一间隔时段，从而使得所述一部分子像素行和所述其他子像素行的显示时间不同，即所述其他子像素行的显示时间比所述一部分子像素行的显示时间长第一间隔时段，从而使得所述一部分子像素行的显示亮度低于所述其他子像素行的显示亮度，造成显示装置不同区域的显示亮度不均一。
需要说明，图4中示意的G1<1>至G1<2160>代表：第一行子像素行对应的扫描信号G1至第2160行子像素行对应的扫描信号G1。
更详细地说，以显示装置包括2160行子像素行为例，以第1行子像素行和第2160行子像素行举例：从图4能够看出第一行子像素行的显示时间为1至2144行子像素行写数据时间，第2160行子像素行显示时间为：第一间隔时段与1至2144行子像素行写数据时间之和，第2160行子像素行显示时间比第1行子像素行显示时间多了一个第一间隔时段，这样就会造成第1行子像素行和第2160行子像素行显示亮度的差异。
基于上述问题的存在，本公开实施例提供了一种显示亮度补偿方法，应用于显示装置，所述显示装置包括多行子像素行；所述多行子像素行划分为第一组子像素行和第二组子像素行，所述第一组子像素行能够在同一帧显示时段内，进行正常显示和插黑显示；所述第二组子像素行能够在当前帧显示时段和相邻的下一帧显示时段内进行正常显示，并能够在所述相邻的下一帧显示时段内进行插黑显示；当前帧显示时段和相邻的下一帧显示时段之间具有第一间隔时段；
