本公开实施例提供的技术方案带来的有益效果至少包括：
在本公开实施例中，根据第一关机补偿过程中的第一侦测电压获取第一位置指示信息，第一位置指示信息用于指示多个子像素中多个第一子像素的位置，且第一子像素的第一侦测电压与第一子像素相邻的第二子像素的第一侦测电压之间的差值绝对值大于第一阈值，这表示该第一位置指示信息对应的第一子像素的第一侦测电压大概率出现了异常。第一子像素的第一侦测电压的异常会导致，根据该第一位置指示信息对应的第一子像素的第一侦测电压计算的第二阈值补偿电压也是异常的，即与第一子像素的驱动TFT的阈值电压相差较远。如果采用第二阈值补偿电压对第一位置指示信息对应的第一子像素进行阈值补偿，会导致第一子像素所在的一列子像素的发光强度较大或者较小，在显示画面中呈现为亮线或者暗线。
而本公开实施例根据第一位置指示信息确定第一阈值补偿电压，第一阈值补偿电压与第一参考值之间的差值的绝对值，小于第二阈值补偿电压与第一参考值之间的差值的绝对值，使得第一阈值补偿电压相对第二阈值补偿电压与第一参考值更接近，即第一阈值补偿电压相对第二阈值补偿电压与第一子像素中驱动TFT的阈值电压更接近。因此，使用第一阈值补偿电压对第一位置指示信息对应的第一子像素进行补偿，能够更好地消除第一子像素的驱动TFT的阈值电压对第一子像素的发光强度的影响，有利于提升显示质量。

具体实施方式
为使本公开的目的、技术方案和优点更加清楚，下面将结合附图对本公开实施方式作进一步地详细描述。
为了便于理解本公开实施例，下面先对显示装置的像素结构和关机补偿过程进行简单的说明。
显示装置的显示区域包括阵列布置的多个像素。每个像素均包括多个子像素。这多个子像素用于发射不同颜色的光。例如，每个像素包括三个子像素，三个子像素分别用于发射红(Red，R)光、蓝(Blue，B)光和绿(Green，G)光。又例如，每个像素包括四个子像素，四个子像素分别用于发射红光、蓝光、绿光和白光。每个子像素均包括发光元件和像素驱动电路。同一子像素中的像素驱动电路与发光元件连接。像素驱动电路用于驱动所连接的发光元件发光。通过控制每个像素的出光颜色和亮度，即可让显示装置显示相应的画面。
上述发光元件的结构包括多种，可以根据实际需要选择设置。例如，上述发光元件可以为有机发光二极管(Organic Light Emitting Diode，OLED)、量子点发光二极管(Quantum Dot Light Emitting Diodes，QLED)或微发光二极管(Micro Light Emitting Diodes，Micro LED)等。
图1是一种像素驱动电路的结构示意图。如图1所示，像素驱动电路包括开关薄膜晶体管(Thin Film Transistor，TFT)T1、驱动TFT T2、电容Cst以及发光元件D。开关TFT T1的栅极连接第一扫描信号线G1，开关TFT T1的源极连接数据信号线，开关TFT T1的漏极与驱动TFT T2的栅极连接。驱动TFT T2的源极连接第一电源线ELVDD，驱动TFT T2的漏极与发光元件D的阳极连接。发光元件D的阴极连接第二电源线ELVSS。电容Cst的一端分别与开关TFT T1的漏极和驱动TFT T2的栅极连接，电容Cst的另一端分别与驱动TFT T2的漏极和发光元件D的阳极连接。
需要说明的是，图1以2T1C(即2个TFT和1个电容)电路为例进行了说 明，在其他实施例中，像素驱动电路中TFT和电容的数量和连接关系也可以根据实际需要进行调整，只要像素驱动电路能够驱动发光元件发光即可。
由于驱动TFT T2的阈值电压在显示装置的使用过程中会发生变化，为了避免该变化影响显示装置的显示效果，可以定期执行关机补偿过程，更新补偿数据，并利用更新后的补偿数据对显示装置的驱动TFT的阈值电压进行补偿。该补偿数据包括每个子像素对应的阈值补偿电压。在执行关机补偿过程后，可以使得每个子像素对应的阈值补偿电压与对应的像素驱动电路中的驱动TFT的阈值电压更接近。
在本公开实施例中，关机补偿是指显示装置在关机时利用侦测线连接的侦测电路对像素驱动电路中的节点S(即驱动TFT T2的漏极、发光元件D的漏极和电容Cst的连接点)的电压进行侦测，然后根据侦测得到的侦测电压计算阈值补偿电压，开机时根据计算的阈值补偿电压对驱动TFT T2的阈值电压进行补偿。
为了实现关机补偿，图1中的像素驱动电路还包括侦测TFT T3，侦测TFT T3的栅极与第二扫描信号线G2连接，侦测TFT T3的源极连接节点S，侦测TFT T3的漏极连接侦测线。通常，同一列的多个像素与同一根侦测线连接。
实际应用中，部分子像素的像素驱动电路中的TFT可能存在制程点不良。出厂时这部分子像素能够正常显示，但是随着显示装置使用时间的加长，会出现像素驱动电路与侦测线发生短路的现象，例如，像素驱动电路的侦测TFT T3的栅极所在的膜层与侦测线发生短路等。当像素驱动电路与侦测线发生短路时，侦测线侦测到的侦测电压会异常偏大或偏小，根据该侦测电压计算得到的阈值补偿电压也会异常偏大或偏小，导致该像素点异常。由于同一列像素的像素驱动电路共用一条侦测线，一个子像素的侦测电压异常会导致这条侦测线连接的所有子像素的侦测电压异常，因此根据侦测电压计算得到的阈值补偿电压也异常。
在关机补偿后，异常的阈值补偿电压会表现为显示装置所显示的画面中出现亮度异常线。这里，亮度异常线也可以称为不良线，是指显示装置在点亮时亮度异常的一列像素，这里，亮度异常是指亮度高于或者低于其他区域。例如，当侦测线与第一电源线之间发生短路时，侦测线侦测得到的侦测电压偏大，根据该侦测电压计算得到的阈值补偿电压偏小，亮度异常线的亮度低于其他区域的亮度，可以称为暗线。当侦测线与第二电源线之间发生短路时，侦测线侦测 得到的侦测电压偏小，根据该侦测电压计算得到的阈值补偿电压偏大，亮度异常线的亮度高于其他区域的的亮度，可以称为亮线。
图2是本公开实施例提供的目标图像存在亮度异常线的示意图。如图2所示，目标图像2中存在亮度异常线201和亮度异常线202，亮度异常线201对应子像素的侦测线与像素驱动电路的第二电源线发生短路，亮度异常线201为亮线，亮度异常线202对应子像素的侦测线与像素驱动电路的第一电源线发生短路，亮度异常线201为暗线。
如果亮度异常线是由侦测线与像素驱动电路之间发生短路引起的，即使重新进行关机补偿，得到的补偿数据仍是异常的，所以开机后使用该补偿数据对对应的子像素进行补偿时仍然会出现亮度异常线。此时一般做法是求助客服或者直接送修，修复周期很长。
为此，本公开实施例提供了一种显示装置的补偿方法，在关机补偿过程中，获取多个子像素的侦测电压，根据侦测电压获取亮度异常线的位置指示信息，根据亮度异常线的位置指示信息确定补偿数据，将亮度异常线对应子像素的驱动TFT的阈值电压作为参考值，使得亮度异常线对应子像素的阈值补偿电压与参考值的差值的绝对值小于基于亮度异常线对应子像素的侦测电压计算的阈值补偿电压与参考值的差值的绝对值。
图3是本公开实施例提供的一种显示装置的补偿方法流程图。参见图3，该方法由显示装置的控制单元，例如时序控制器(Time Controller，TCON)执行，该方法包括：
在步骤301中，在第一关机补偿过程中，获取多个子像素的第一侦测电压。
这里，多个子像素为显示装置的显示区域中的所有子像素，第一侦测电压是每个子像素连接的侦测线输出的电压，即前述节点S的电压。
在一些示例中，该第一关机补偿过程可以是根据接收到的用户指令执行的，该用户指令用于指示执行关机补偿过程。该用户指令可以是从遥控设备或者显示装置上的按键接收到的。
在步骤302中，根据多个子像素的第一侦测电压，获取第一位置指示信息。
其中，第一位置指示信息用于指示多个子像素中多个第一子像素所属像素的列位置，多个第一子像素与第一侦测线连接，且多个第一子像素中任一第一子像素的第一侦测电压与第二子像素的第一侦测电压之间的差值的绝对值均大 于第一阈值，第二子像素为第一侦测线相邻的第二侦测线连接的子像素。
需要说明的是，在本公开实施例中，第一位置指示信息对应的像素可能是一列像素也可能是多列像素，第一子像素所属像素可以为出现异常的一列像素或者出现异常的多列像素中的任一列像素。
在本公开实施例中，行为扫描线的延伸方向，列为数据线和侦测线的延伸方向。在一些示例中，行为水平方向，列为竖直方向。在另一些示例中，行为竖直方向，列为水平方向。
在步骤303中，根据第一位置指示信息，确定第一补偿数据。
其中，第一补偿数据包括多个子像素的第一阈值补偿电压，第一补偿数据中，第一子像素的第一阈值补偿电压与第一参考值之间的差值的绝对值小于第一子像素的第二阈值补偿电压与第一参考值之间的差值的绝对值，第一参考值为第一子像素的驱动TFT的阈值电压，第一子像素的第二阈值补偿电压是基于第一子像素的第一侦测电压计算的。
在本公开实施例中，第一补偿数据保存在显示装置的控制板中。例如，保存在显示装置的TCON中。
在本公开实施例中，根据第一关机补偿过程中的第一侦测电压获取第一位置指示信息，第一位置指示信息用于指示多个子像素中多个第一子像素所属像素的列位置，且第一子像素的第一侦测电压与第一子像素相邻的第二子像素的第一侦测电压之间的差值绝对值大于第一阈值，这表示该第一位置指示信息对应的第一子像素的第一侦测电压大概率出现了异常。第一子像素的第一侦测电压的异常会导致，根据该第一位置指示信息对应的第一子像素的第一侦测电压计算的第二阈值补偿电压也是异常的，即与第一子像素的驱动TFT的阈值电压相差较远。如果采用第二阈值补偿电压对第一位置指示信息对应的第一子像素进行阈值补偿，会导致第一子像素所属的一列像素的发光强度较大或者较小，在显示画面中呈现为亮线或者暗线。
而本公开实施例根据第一位置指示信息确定第一阈值补偿电压，第一阈值补偿电压与第一参考值之间的差值的绝对值，小于第二阈值补偿电压与第一参考值之间的差值的绝对值，使得第一阈值补偿电压相对第二阈值补偿电压与第一参考值更接近，即第一阈值补偿电压相对第二阈值补偿电压与第一子像素中驱动TFT的阈值电压更接近。因此，使用第一阈值补偿电压对第一位置指示信 息对应的第一子像素进行补偿，能够更好地消除第一子像素的驱动TFT的阈值电压对第一子像素的发光强度的影响，有利于提升显示质量。
图4是本公开实施例提供的另一种显示装置的补偿方法流程图。参见图4，该方法由显示装置的控制单元，例如TCON执行，该方法包括：
在步骤401中，在第一关机补偿过程中，获取多个子像素的第一侦测电压。
这里，第一关机补偿过程、多个子像素和第一侦测电压含义参见步骤301中描述，在此省略详细描述。
在步骤402中，根据多个子像素的第一侦测电压，获取第一位置指示信息。
这里，第一位置指示信息的含义参见步骤301中描述，在此省略详细描述。
在一种可能的实施方式中，按照如下方式获取第一位置指示信息：
当第一目标子像素的第一侦测电压与两个第二目标子像素的第一侦测电压之间的差值的绝对值均大于第一阈值时，将第一目标子像素所属像素的列位置确定为第一位置指示信息。
其中，第一目标子像素为多个子像素中的任一个，进一步地，第一目标子像素为多个第一子像素中的任一个。两个第二目标子像素所属的像素与第一目标子像素所属的像素位于同一行、且两个第二目标子像素分别与第一侦测线相邻的两根侦测线连接。
示例性地，由于在关机补偿过程中，是按照同一行中发射相同颜色光的子像素依次扫描，因此第一目标子像素与第二目标子像素为发射相同颜色光的子像素。例如，假设每个像素包括R、G、B三个子像素，则会先获取所有的R子像素的侦测电压，再获取所有G子像素的侦测电压，最后获取所有的B子像素的侦测电压。
在一些示例中，该第一阈值可以根据设置指令设置，该设置指令是通过遥控设备或者显示装置的按键接收到的。示例性地，遥控设备包括遥控器或者终端。在另一些示例中，该第一阈值可以为默认值。
在步骤403中，根据第一位置指示信息，确定第一补偿数据。
步骤403包括：采用以下方式中的任一种确定第一子像素的第一阈值补偿电压：
第一种、根据与第一子像素位于同一行、且与第一侦测线相邻的侦测线连接的子像素的第一侦测电压，计算第一子像素的第一阈值补偿电压。例如，根 据与第一子像素位于同一行、且与第一侦测线相邻的前一根侦测线或与第一侦测线相邻的后一根侦测线连接的子像素的第一侦测电压，计算第一子像素的第一阈值补偿电压。
第二种、根据与第一子像素位于同一行、且与第一侦测线相邻的至少两根侦测线连接的至少两个子像素的第一侦测电压的均值，计算第一子像素的第一阈值补偿电压。例如，根据与第一子像素位于同一行、且与第一侦测线相邻的前后两根侦测线连接的前一子像素和后一子像素的第一侦测电压的均值，计算第一子像素的第一阈值补偿电压。
第三种、将与第一子像素位于同一行、且与第一侦测线相邻的侦测线连接的子像素的第一阈值补偿电压，作为第一子像素的第一阈值补偿电压。例如，将与第一子像素位于同一行、且与第一侦测线相邻的前一根侦测线或与第一侦测线相邻的后一根侦测线连接的子像素的第一阈值补偿电压，作为第一子像素的第一阈值补偿电压。
第四种、将与第一子像素位于同一行、且与第一侦测线相邻的至少两根侦测线连接的至少两个子像素的第一阈值补偿电压的均值，作为第一子像素的第一阈值补偿电压。例如，将与第一子像素位于同一行、且与第一侦测线相邻的前后两根侦测线连接的前一子像素和后一子像素的第一阈值补偿电压的均值，作为第一子像素的第一阈值补偿电压。
第五种、将第三关机补偿过程中的第一子像素的第三阈值补偿电压作为第一子像素的第一阈值补偿电压。其中，第三关机补偿过程为第一关机补偿过程的前一次关机补偿过程，且第三关机补偿过程后第一子像素的第三阈值补偿电压与第一参考值的差值的绝对值小于第一子像素的第二阈值补偿电压与第一参考值之间的差值的绝对值。
这样，在显示装置后续显示的过程中，采用第一补偿数据对第一子像素进行补偿。
如前所述，由于在关机补偿过程中是按照同一行中发射相同颜色光的子像素依次扫描，所以以上方式中，第一子像素和与第一子像素位于同一行、且与第一侦测线相邻的侦测线连接的子像素为相同颜色的子像素。
图5是本公开实施例提到的一种更新补偿数据的示意图。如图5所示，第2个子像素的侦测电压与相邻的第1个子像素和第3个子像素的侦测电压之间的 差值大于第一阈值，因此确定第2个子像素的侦测电压出现异常。将相邻的第1个子像素或者第3个子像素的侦测电压作为第2个子像素的侦测电压，这样第2个子像素的侦测电压与第1个子像素和第3个子像素的侦测电压持平，根据侦测电压计算得到的第2个子像素的第一补偿数据与第1个子像素和第3个子像素的第一补偿数据也持平。
可选地，步骤403还包括：对于第一子像素之外的其他子像素，根据其他子像素的第一侦测电压，计算其他子像素的第一阈值补偿电压。
在本公开实施例中，当第一关机补偿过程结束后，显示装置显示至少一幅测试图像。在一些示例中，测试图像为纯色图像，有利于突出显示亮度异常线。
在一些示例中，测试图像的数量与一个像素包含的子像素的数量相等，且颜色相同。例如，当一个子像素包括红色子像素、蓝色子像素和绿色子像素这三个子像素时，显示装置在第一关机补偿过程结束后，显示的测试图像为三幅，分别为红色图像、蓝色图像和绿色图像。在另一些示例中，测试图像可以为具有任意图案的图像，或者，与各个子像素的颜色不同的图像。
当测试图像中均不存在亮度异常线时，表示利用第一补偿数据对显示装置的所有子像素进行补偿的效果较好，后续一段时间内，可以使用该第一补偿数据进行阈值补偿。
当测试图像的任一幅中还存在亮度异常线时，表示利用第一补偿数据对显示装置的所有子像素进行补偿的效果不能满足需求，此时可以根据用户指令执行第二关机补偿过程。这种情况下，该方法还包括：
在步骤404中，在第二关机补偿过程中，获取多个子像素的第二侦测电压。
其中，第二关机补偿过程为第一关机补偿过程的下一次关机补偿过程。
在步骤405中，当第三目标子像素的第二侦测电压与两个第四目标子像素的第二侦测电压之间的差值的绝对值均大于第二阈值时，将第三目标子像素所属像素的列位置确定为第二位置指示信息。
这里，第三目标子像素为多个子像素中的任一个，第三目标子像素与第三侦测线连接，两个第四目标子像素所属的像素与第三目标子像素所属的像素位于同一行、且两个第四目标子像素分别与第三侦测线相邻的两根侦测线连接，第二阈值小于第一阈值。通过减小第一阈值，使得根据侦测电压和第二阈值，更容易确定亮度异常线的位置。
示例性地，第三目标子像素可以与第一目标子像素为相同的子像素，第三目标子像素可以与第一目标子像素为不同的子像素。
在一些示例中，第二阈值的取值可以是根据用户输入的设置指令确定的。例如，该设置指令用于直接指示第二阈值的取值，或者，该设置指令用于指示在将第一阈值减小设定比例(例如减小第一阈值的30％)或者减小设定差值，得到第二阈值。相应地，该方法还包括：根据设置指令设置第二阈值，该设置指令是通过遥控设备或者显示装置的按键接收到的。示例性地，该设置指令可以是在第二关机补偿过程开始之前接收到的。
在另一些示例中，可以在两次关机补偿过程之间的间隔小于时间阈值的情况下，基于第一阈值自动确定第二阈值。例如，将第一阈值减小设定比例或者减小设定差值，得到第二阈值。
在步骤406中，根据第二位置指示信息，确定第二补偿数据。
这里，第二补偿数据包括多个子像素的第三阈值补偿电压，第二补偿数据中，第三目标子像素的第三阈值补偿电压与第二参考值之间的差值的绝对值小于第三目标子像素的第四阈值补偿电压与第二参考值之间的差值的绝对值，第二参考值为第三目标子像素的驱动TFT的阈值电压，第三目标子像素的第四阈值补偿电压是基于第三目标子像素的第二侦测电压计算的。
该步骤406中，确定第二补偿数据的方式，与步骤403中确定第一补偿数据的方式相同，在此省略详细描述。
当第二关机补偿过程结束后，如果第二关机补偿过程结束后显示的测试图像中还存在亮度异常线，可以根据用户指令执行第四关机补偿过程。第四关机补偿的过程与第二关机补偿的过程相同。且第四关机补偿过程中的第三阈值小于第二阈值。第三阈值和第二阈值的关系可以参见前述第二阈值和第一阈值的关系，在此省略详细描述。
当第二关机补偿过程结束后，如果第二关机补偿过程结束后显示的测试图像中出现的亮度异常线的数量增加，表示亮度异常线可能不是由于侦测线短路造成的，需要反馈给客服进行处理。
在本公开实施例中，通过第一子像素的侦测电压和与第一侦测线相邻的两根侦测线连接的两个子像素的侦测电压之间的差值的绝对值大于阈值时，确定亮度异常线的位置指示信息。这种确定亮度异常线的位置指示信息的方式简单， 计算量小。
此外，在关机补偿过程结束后显示画面中还存在亮度异常线时，还可以减小阈值，重新进行执行关机补偿过程，进一步加大了修复亮度异常线的概率。
图6是本公开实施例提供的又一种显示装置的补偿方法流程图。参见图6，该方法由显示装置的控制单元，例如TCON执行，该方法包括：
在步骤601中，在第一关机补偿过程中，获取多个子像素的第一侦测电压。
这里，第一关机补偿过程、多个子像素和第一侦测电压的含义参见步骤301中描述，在此省略详细描述。
在步骤602中，根据多个子像素的第一侦测电压，确定第三补偿数据。
在步骤603中，基于第三补偿数据和目标图像的图像数据，控制显示装置显示目标图像。
这里，目标图像可以为前述测试图像。
在步骤604中，根据用户指令获取第一位置指示信息。
这里，用户指令是基于目标图像中的亮度异常线的位置产生的。第一位置信息的含义参见步骤302中描述，在此省略详细描述。
可选地，按照如下方式根据用户指令获取第一位置指示信息：
第一步，根据用户操作，在目标图像中移动光标。
第二步，接收用户指令。
这里，用户指令用于指示将光标对应的子像素的位置确定为第一位置指示信息。示例性地，根据用户操作，将光标移动至目标图像中的亮度异常线的位置，根据光标移动可以测出亮度异常线的位置与目标图像的边框的距离，根据距离和目标图像的像素分辨率，可以将该位置转换为像素位置。
在步骤605中，根据第一位置指示信息，确定第一补偿数据。
在步骤605中确定第一补偿数据的方式，与步骤403相同，在此省略详细描述。
在本公开实施例中，根据用户操作移动光标来获取第一位置指示信息，简化了显示装置的处理流程。再根据第一位置指示信息，来确定第一补偿数据，不需要多次执行关机补偿过程，补偿数据的处理过程耗时短。
需要说明的是，图6所示的补偿方法可以在图5所示的补偿方法中的关机补偿过程执行次数达到设定次数，但仍然存在亮度异常线的情况下执行。或者， 可以不依赖于图5所示的补偿方法，在显示装置显示的画面中出现亮度异常线的情况下执行。
图7是本公开实施例提供的另一种显示装置的补偿方法流程图。如图7所示，该方法由显示装置的控制单元，例如TCON执行，该方法包括：
在步骤701中，获取第一补偿数据。
其中，第一补偿数据是显示装置执行第一关机补偿过程获得的，第一补偿数据包括多个第一子像素的第一阈值补偿电压和多个第二子像素的第一阈值补偿电压，多个第一子像素与第一侦测线连接，多个第二子像素与第一侦测线相邻的第二侦测线连接，第一子像素的第一阈值补偿电压与第二子像素的第一阈值补偿电压之间的差值的绝对值大于电压阈值。
第一子像素的第一阈值补偿电压为异常电压，第一子像素的第一阈值补偿电压与第一子像素的驱动TFT的目标阈值电压之间的差值的绝对值大于第一设定值。第二子像素的第一阈值补偿电压为正常电压，第二子像素的第一阈值补偿电压与第二子像素的驱动TFT的目标阈值电压之间的差值的绝对值小于或等于第二设定值。而各个子像素的驱动TFT的目标阈值电压接近，因此第一子像素的第一阈值补偿电压与第二子像素的第一阈值补偿电压之间的差值的绝对值大于电压阈值。
在步骤702中，获取位置指示信息。
其中，位置指示信息用于指示多个第一子像素所属像素的列位置。
可选地，按照如下方式获取位置指示信息：
在第一关机补偿过程中，当第一目标子像素的侦测电压与两个第二目标子像素的侦测电压之间的差值的绝对值均大于阈值时，将第一目标子像素所属像素的列位置保存为位置指示信息，两个第二目标子像素所属的像素与第一目标子像素所属的像素位于同一行、且两个第二目标子像素与第一侦测线相邻的两根侦测线连接。或者，根据用户指令生成位置指示信息，用户指令是基于目标图像中的亮度异常线的位置产生的，目标图像为显示装置执行第一关机补偿过程后显示的图像。
在步骤703中，根据位置指示信息和第一补偿数据，对待显示画面的第一显示数据进行补偿，得到第二显示数据。
其中，第一显示数据包括多个子像素的第一数据电压，第二显示数据包括 多个子像素的第二数据电压，且在第二显示数据中，第一子像素的第二数据电压与第一子像素的第一数据电压的差值的绝对值小于第一阈值补偿电压的绝对值。
可选地，采用以下任一种方式确定第一子像素的第二数据电压：
采用与第一子像素位于同一行、且与第一侦测线相邻的侦测线连接的子像素的第一阈值补偿电压对第一子像素的第一数据电压进行补偿，得到第一子像素的第二数据电压。
采用第一子像素的第二阈值补偿电压对第一子像素的第一数据电压进行补偿，得到第一子像素的第二数据电压。其中，第一子像素的第二阈值补偿电压是显示装置执行第二关机补偿过程得到的，第二关机补偿过程是第一关机补偿过程的前一次关机补偿过程，且显示装置采用第二补偿数据进行补偿时，多个第一子像素所属像素对应的位置未产生亮度异常线。
可选地，采用第二子像素的第一阈值补偿电压对第二子像素的第一数据电压进行补偿，得到第二子像素的第二数据电压。
