实施例一
本公开实施例提供了一种像素补偿方法，可用于显示面板，此显示面板包括多行 有机发光子像素组，有机发光子像素组包括多个在列方向上排布的有机发光子像素，多行有机发光子像素组的至少一组为侦测行。
如图1所示，本实施例的像素补偿方法可包括步骤S100、步骤S102、步骤S104、步骤S106及步骤S108，其中：
在步骤S100中，确定侦测行中每个有机发光子像素的实际驱动数字电压；也就是说，此步骤可获得多个实际驱动数字电压，每个实际驱动数字电压对应属于一个有机发光子像素，应当理解的是，每个有机发光子像素的实际驱动数字电压可相同也可不相同。
详细说明，如图2所示，步骤S100可包括：
步骤S1001，获取侦测行中每个有机发光子像素输出的实际驱动模拟电压；
步骤S1002，对实际驱动模拟电压进行模数转换，以转换成实际驱动数字电压。
在步骤S102中，基于侦测行中每个有机发光子像素的实际驱动数字电压进行均值计算，以确定侦测行对应的平均驱动数字电压。举例而言，在侦测行为一行，且一行包括N个有机发光子像素时，这样获取到的实际驱动数字电压具有N个，N个实际驱动数字电压相加在除以N，即：可得到此侦测行对应的平均驱动数字电压。在侦测行为M行，且一行包括N个有机发光子像素时，这样获取到的实际驱动数字电压具有M×N个，M×N个实际驱动数字电压相加在除以M×N，即：可得到此M行侦测行对应的平均驱动数字电压。
应当理解的是，此N、M为大于1的整数。
在步骤S104中，计算侦测行中每个有机发光子像素的实际驱动数字电压与平均驱动数字电压的电压差值，并将各电压差值进行统计以形成电压差值集合。应当理解的是，侦测行中每个有机发光子像素的实际驱动数字电压存在不同时，则电压差值集合中各电压差值存在正值和负值，还可存在零。
在步骤S106中，在电压差值集合中的最大电压差值的绝对值大于或等于目标阈值时，向侦测行中每个有机发光子像素输出与之对应的数据补偿模拟电压。
需要说明的是，此目标阈值对应的亮度差异为人肉眼可以看出的差异，因此，在电压差值集合中的最大电压差值的绝对值大于或等于目标阈值时，则说明此最大电压差值对应的有机发光子像素存在阈值电压Vth发生严重漂移的情况，显示亮度出现明显异常，存在明显显示不均的情况，此时，则需要对显示面板进行数据补偿，具体可向有机发光子像素输出与之对应的数据补偿模拟电压，以平衡各有机发光子像素的发 光亮度，从而改善显示不均的情况，提高显示效果。
详细说明，如图3所示，步骤S106中可包括：
步骤S1061，基于补偿计算公式计算侦测行中每个有机发光子像素对应的数据补偿数字电压，补偿计算公式为：DATA 补＝DATA 原－k×DATA 差+m，其中，DATA 补为数据补偿数字电压，DATA 原为有机发光子像素对应的原始数据数字电压，DATA 差为电压差值，k为第一正常数，m为第二正常数；
步骤S1062，对数据补偿数字电压进行数模转换，以转换成数据补偿模拟电压；
步骤S1063，向侦测行中每个有机发光子像素输出与之相匹配的数据补偿模拟电压。
应当理解的是，在电压差值DATA 差为负值时，则说明此有机发光子像素对应的实际驱动数字电压小于平均驱动数字电压，为了使得有机发光子像素对应的实际驱动数字电压更靠近平均驱动数字电压，则提供给此有机发光子像素的数据补偿数字电压需要比原始数据数字电压大，从而使得有机发光子像素获取到的数据补偿模拟电压需要比原始数据数字模拟电压大。
而在电压差值DATA 差为正值时，则说明此有机发光子像素对应的实际驱动数字电压大于平均驱动数字电压，为了使得有机发光子像素对应的实际驱动数字电压更靠近平均驱动数字电压，则提供给此有机发光子像素的数据补偿数字电压需要比原始数据数字电压小，从而使得有机发光子像素获取到的数据补偿模拟电压需要比原始数据数字模拟电压小。
另外，在电压差值DATA 差为零时，则说明此有机发光子像素对应的实际驱动数字电压等于平均驱动数字电压，则说明不需要补偿，继续向有机发光子像素提供你原始数据数字模拟电压即可。
举例而言，第一正常数K基于获取实际驱动模拟电压过程中的线路损耗调整确定，第二正常数m基于模数转换过程的转换误差调整确定，也就是说，本年实施例的像素补偿方法除了可以对有机发光子像素内驱动晶体管的阈值电压Vth进行补偿，还可对线路损耗以及转换误差进行补偿，在改善显示不均问题的同时，还可提高显示亮度。
在本实施例中，第一正常数K可为1，第二正常数m可为0，也就是说，本实施例像素补偿方法可以只对有机发光子像素内驱动晶体管的阈值电压Vth进行补偿，不考虑外部其他损耗和转换误差的补偿，因为，在侦测每个有机发光子像素均会存在一 定的线路损耗和转换误差，且基本差不太多，也就是说，线路损耗和转换误差比较均衡，只要对有机发光子像素内驱动晶体管的阈值电压Vth进行补偿后，线路损耗和转换误差即使不补偿，也基本不会出现个别显示亮度明显异常的情况，这样肉眼基本不会看到显示不均的情况，即：显示效果良好，同时，还可降低补偿方法的计算复杂性，降低补偿过程中所耗能量。
在步骤S108中，在电压差值集合中的最大电压差值小于目标阈值时，向侦测行中每个有机发光子像素输出原始数据模拟电压。
也就是说，在电压差值集合中的最大电压差值的绝对值小于目标阈值时，则说明侦测的各有机发光子像素的阈值电压Vth基本不发生漂移，或者即使存在漂移，但整体偏移比较均衡，不会出现个别显示亮度明显异常的情况，这样肉眼基本不会看到显示不均的情况，即：显示效果良好，此时，可以不进行数据补偿，直接向有机发光子像素继续输出其对应的原始数据模拟电压，这样可降低补偿过程中所需要的能耗。
在本实施例中，多行有机发光子像素组中侦测行设置有多行，且等间隔排布，也就是说，本实施例的像素补偿方法可对多行有机发光子像素组进行侦测，这样可以更好地反应显示亮度均一性的问题，提高补偿精准性。
实施例二
本实施例二提供了一种像素补偿装置，用于对显示面板进行补偿，此像素补偿装置用于实现实施例一所描述的像素补偿方法。具体地，如图4所示，像素补偿装置可包括依次连接的确定模块101、均值计算模块102、差值计算统计模块103及补偿输出模块104。
其中，确定模块101用于确定侦测行中每个有机发光子像素的实际驱动数字电压。
均值计算模块102用于基于侦测行中每个有机发光子像素的实际驱动数字电压进行均值计算，以确定侦测行对应的平均驱动数字电压。
差值计算统计模块103用于计算侦测行中每个有机发光子像素的实际驱动数字电压与平均驱动数字电压的电压差值，并将各电压差值进行统计以形成电压差值集合。
补偿输出模块104用于在电压差值集合中的最大电压差值的绝对值大于或等于目标阈值时，向侦测行中每个有机发光子像素输出与之对应的数据补偿模拟电压。
其中，补偿输出模块104还用于在电压差值集合中的最大电压差值小于目标阈值时，向侦测行中每个有机发光子像素输出原始数据模拟电压。
具体地，如图4所示，确定模块101可包括模数转换器(简称：ADC)1011，模数转换器1011用于获取侦测行中每个有机发光子像素输出的实际驱动模拟电压，并对实际驱动模拟电压进行模数转换，以转换成实际驱动数字电压。应用理解的是，此确定模块101还可包括连接模数转换器1011与有机发光子像素的传送走线等等。
如图4所示，补偿输出模块104可包括相连接的补偿计算模块1041和数模转换器(简称：DAC)1042，补偿计算模块1041用于基于补偿计算公式计算侦测行中每个有机发光子像素对应的数据补偿数字电压，补偿计算公式为：DATA 补＝DATA 初－k×DATA 差+m，其中，DATA 补为数据补偿数字电压，DATA 初为有机发光子像素对应的原始数据数字电压，DATA 差为电压差值，k为第一正常数，m为第二正常数；数模转换器1042用于对数据补偿数字电压进行数模转换，以转换成数据补偿模拟电压，并向侦测行中每个有机发光子像素输出与之相匹配的数据补偿模拟电压。
其中，在电压差值集合中的最大电压差值小于目标阈值时，补偿计算模块1041不需要重新补偿电压，直接向侦测行中每个有机发光子像素输出原始数据模拟电压即可，这样可降低补偿过程中所需能耗。
此外，需要说明的是，本实施例的像素补偿装置中涉及到其他与实施例一相关的内容，均可参考实施例一的描述，在此不再重复赘述。

举例而言，数据驱动器10a包括分别与时序控制器10b连接的模数转换器1011和数模转换器1042，本实施例的数模转换器1042和模数转换器1011的作用可参考实施例二中像素补偿装置中所描述的内容，在此不再重复赘述。应当理解的是，本实施例和实施例二中提到的数模转换器1042还可对时序控制器10b提供的原始数据数字电压进行数模转换，以转换成原始数据模拟电压。
其中，本实施例的时序控制器10b可包括均值计算模块102、差值计算统计模块103和补偿计算模块1041，本实施例的均值计算模块102、差值计算统计模块和补偿计算模块1041的作用可参考实施例二中像素补偿装置中所描述的内容，在此不再重复赘述。
