除非另外定义，本公开使用的技术术语或者科学术语应当为本公开所属领域内具有一般技能的人士所理解的通常意义。本公开中使用的“第一”、“第二”以及类似的词语并不表示任何顺序、数量或者重要性，而只是用来区分不同的组成部分。同样，“一个”、“一”或者“该”等类似词语也不表示数量限制，而是表示存在至少一个。“包括”或者“包含”等类似的词语意指出现该词前面的元件或者物件涵盖出现在该词后面列举的元件或者物件及其等同，而不排除其他元件或者物件。“连接”或者“相连”等类似的词语并非限定于物理的或者机械的连接，而是可以包括电性的连接，不管是直接的还是间接的。“上”、“下”、“左”、“右”等仅用于表示相对位置关系，当被描述对象的绝对位置改变后，则该相对位置关系也可能相应地改变。
随着用户对手机屏幕的要求越来越高，目前厂商都推出了采用“全面屏”的手机产品。但由于在手机正面还需要设置摄像头、光线传感器、距离传感器等器件，所以，目前的大多数“全面屏”手机的屏幕都有“刘海区”(notch区)。图1A示出了一种具有“刘海区”的显示面板的示意图，如图1A所示，该显示面板的显示区域包括第一区域111和第二区域112，第一区域111和第二区域112为不同区域，显示区域用于显示图像。另外，该显示面板还包括“刘海区”120，例如摄像头、光线传感器、距离传感器等器件设置在该“刘 海区”120中，所以，通常情况下该“刘海区”120不能用于显示图像。第一区域111为靠近“刘海区”120的区域，第二区域112为显示区域中除了第一区域111外的其它区域。
需要说明的是，图1A仅是示意性的示出一种具有“刘海区”的显示面板，本公开的实施例对“刘海区”的位置以及大小不作限定。另外，关于第一区域111与第二区域112的大小也是示意性的，以下各实施例与此相同，不再赘述。
如图1A所示，由于该显示面板的“刘海区”120中需要设置摄像头等器件，这些器件需要对应地设置信号走线以及驱动电路(或检测电路)，所以“刘海区”120附近的区域即第一区域111的面板布局和第二区域112的面板布局会存在差异。另外，该显示面板的驱动电路(或驱动芯片)一般设置在远离第一区域111的一端，该显示面板的显示扫描例如是从远离驱动电路的远端开始向靠近驱动电路的近端进行扫描操作的，由于第一区域111中的像素单元相对于第二区域112中的像素单元距离驱动电路较远，所以用于驱动第一区域111中的像素单元的信号走线的压降(IR Drop)要大于用于驱动第二区域112中的像素单元的信号走线的压降，所以该显示面板可能会出现显示不均(mura)问题，例如，第一区域111中的像素单元的亮度低于第二区域112中的像素单元的亮度，该显示面板显示图像时可能会出现明显的分块显示现象。
图1B为图1A中的显示面板进行显示时位于不同位置处的亮度变化曲线。如图1B所示，横坐标表示该显示面板的行数，例如，该显示面板包括3120行像素单元，纵坐标表示对应位置处的亮度。如图1B所示，由于面板布局以及压降不同造成的影响，第一区域111中可能包括亮度最低的区域，在第二区域112中随着行数的增大，亮度逐渐增大。
对于上述图1A所示的显示面板出现的显示不均问题，可以采用一种亮度补偿方法对该显示面板的亮度进行补偿，从而改善或避免该显示不均问题。
例如，如图1A所示，首先在第二区域112中选取一个目标区域TG，例如，该目标区域TG包括位于第二区域112的中心位置处的像素单元，例如该目标区域TG包括100行100列像素单元，需要说明的是，本公开的实施例对目标区域TG的大小不作限定。
然后将目标区域TG的亮度取平均值作为目标亮度，该显示面板中除了目标区域TG外的其它区域都以该目标亮度为基准进行亮度补偿。例如，该显示面板为OLED(Organic Light-Emitting Diode)显示面板，可以通过调整提供给每个像素单元的灰阶值来改变该像素单元的亮度。
例如，当灰阶值采用8比特(0～255共256个灰阶值)的数据表示时，最高灰阶值为255。例如，当提供至该显示面板的全部像素单元的灰阶值为255时，即要显示最高亮度，则此时在第一区域111和第二区域112中可能会出现低于目标区域TG的目标亮度的像素单元，此时由于比特位数的限制，这些像素单元无法再通过提高灰阶值来提高亮度从而无法进行亮度补偿。另外，由于第一区域111和第二区域112的面板布局差异较大，所以如果第一区域111中的像素单元也采用第二区域112中的目标区域的亮度数据进行补偿，则可能无法进行有效的亮度补偿。
本公开至少一实施例提供一种显示面板的亮度补偿参数检测方法，显示面板的显示区域包括第一区域和第二区域，第一区域包括按照第一阵列排布的多个第一像素单元，第二区域包括按照第二阵列排布的多个第二像素单元，第一区域和第二区域为不同区域，亮度补偿参数检测方法包括：从第一区域中选取第一目标区域，按照第一目标区域的亮度确定第一补偿参数，以用于第一区域中的至少部分第一像素单元按照第一补偿参数进行亮度补偿；以及从第二区域中选取第二目标区域，按照第二目标区域的亮度确定第二补偿参数，以用于第二区域中的至少部分第二像素单元按照第二补偿参数进行亮度补偿。本公开至少一实施例还提供对应于上述亮度补偿参数检测方法的亮度补偿方法、亮度补偿参数检测装置、亮度补偿装置、显示装置及存储介质。
本公开的至少一实施例提供的亮度补偿参数检测方法、亮度补偿方法、亮度补偿参数检测装置、亮度补偿装置、显示装置及存储介质，可以对显示面板中的不同区域分别进行亮度补偿，从而改善或避免显示面板的不同区域之间的亮度不均等显示不良问题。
下面结合附图对本公开的一些实施例进行详细说明。
本公开的至少一实施例提供一种显示面板的亮度补偿参数检测方法，该亮度补偿参数检测方法可以对显示面板的亮度进行补偿参数检测，例如获得的补偿参数可以用于显示面板进行显示操作时对亮度进行补偿。例如，图2 示出了一种显示面板，该显示面板的显示区域包括第一区域111和第二区域112，第一区域111包括按照第一阵列排布的多个第一像素单元，第二区域112包括按照第二阵列排布的多个第二像素单元，第一区域111和第二区域112为不同区域。例如，如图2所示，该显示面板可以是包括“刘海区”120的OLED显示面板。例如，第一区域111为靠近“刘海区”120的区域，第二区域112为该显示面板的显示区域中除了第一区域111外的其它区域。例如，该显示面板的第一区域111和第二区域112是用于显示图像的区域，“刘海区”120中一般设置有例如摄像头、传感器等器件，该“刘海区”120一般不用于显示图像。
需要说明的是，在本公开的实施例中，关于第一区域111和第二区域112的划分不限于图2所示的情形，根据实际需要还可以采用其它方式进行划分，本公开的实施例对此不作限定。本公开的实施例提供的亮度补偿参数检测方法是用于面板布局差异较大的两个区域，所以只要在显示面板的显示区域中选择两个不同的区域，均可以实施上述亮度补偿参数检测方法。
例如，如图2所示，该显示面板中的第一区域111中的第一像素单元和第二区域112中的第二像素单元的大小可以相同。本公开的实施例包括但不限于此，例如，显示面板中的第一区域111中的第一像素单元和第二区域112中的第二像素单元的大小也可以不同。
需要说明的是，在本公开的实施例中，将显示面板中用于显示图像的区域称为显示区域，将设置器件而不用于显示图像的区域称为“刘海区”，以下各实施例与此相同，不再赘述。
例如，该亮度补偿参数检测方法包括如下操作步骤。
步骤S100：从第一区域111中选取第一目标区域TG1，按照第一目标区域TG1的亮度确定第一补偿参数；例如，该第一补偿参数用于第一区域111中的至少部分第一像素单元进行亮度补偿。
步骤S200：从第二区域112中选取第二目标区域TG2，按照第二目标区域TG2的亮度确定第二补偿参数；例如，该第二补偿参数用于第二区域112中的至少部分第二像素单元进行亮度补偿。
例如，第一目标区域TG1在选取时可以使得第一目标区域TG1包括第一区域111中亮度低于预设值的第一像素单元，例如，包括第一区域111中 亮度最低的第一像素单元。例如，该第一目标区域TG1可以包括50行50列第一像素单元，本公开的实施例包括但不限于此，例如第一目标区域TG1还可以包括更多或更少的第一像素单元。例如，第一区域111包括位于显示面板一侧的凸出区域，该凸出区域即为靠近“刘海区”120的区域。
例如，第二目标区域TG2在选取时可以使得第二目标区域TG2包括第二区域112中位于中心位置处的第二像素单元。例如，假设该显示面板包括3120行像素单元(第一像素单元和第二像素单元)，则第二目标区域TG2可以包括位于第1560行的第二像素单元。例如，该第二目标区域TG2可以包括100行100列第二像素单元，本公开的实施例包括但不限于此，例如第二目标区域TG2还可以包括更多或更少的第二像素单元。例如，第二区域112包括显示区域中位于中心位置处的区域，即第二区域112为显示面板的显示区域中除了第一区域111外的其它区域。
在本公开的一些实施例提供的亮度补偿参数检测方法中，从第一区域111中选取第一目标区域TG1，然后确定第一补偿参数，该第一补偿参数用于第一区域111中的至少部分第一像素单元进行亮度补偿；并从第二区域112中选取第二目标区域TG2，然后确定第二补偿参数，该第二补偿参数用于第二区域112中的至少部分第二像素单元进行亮度补偿。由上述可知，第一区域111和第二区域112的面板布局差异较大，所以第一区域111中的第一像素单元的特性和第二区域112中的第二像素单元的特性差异较大。该亮度补偿参数检测方法针对第一区域111和第二区域112分别获取对应的补偿参数，可以改善或避免显示面板的第一区域111和第二区域112之间的亮度不均等显示不良问题。例如，上述亮度补偿参数检测方法可以在厂家端对显示面板进行操作以获得补偿参数(第一补偿参数和第二补偿参数)，然后例如可以在用户端采用该补偿参数对显示面板进行亮度补偿。
在本公开的一些实施例提供的亮度补偿参数检测方法中，例如，第一区域111被划分为多个第一补偿单元(或像素单元组)，第一补偿单元包括一组像素单元，该像素单元组包括至少一个第一像素单元，上述按照第一目标区域TG1的亮度确定第一补偿参数包括如下操作步骤。
步骤S110：根据显示面板自身的伽玛曲线获得每个第一补偿单元的亮度数据对应的灰阶数据，每个第一补偿单元根据第一目标区域TG1对应的灰阶 数据确定对应的第一补偿参数。
例如，图4示出了一种显示面板的灰阶值和透过率关系的伽玛曲线，该显示面板的伽玛值(Gamma)为2.2，透过率等于亮度和最大亮度的比值。需要说明的是，本公开的实施例对显示面板的伽玛值不作限定。在上述步骤S110中，可以根据显示面板的伽玛曲线将亮度数据转换为对应的灰阶数据，然后根据灰阶数据获得每个第一补偿单元对应的第一补偿参数。
例如，每个第一补偿单元包括4行4列第一像素单元，本公开的实施例包括但不限于此，该第一补偿单元还可以包括更多或更少个第一像素单元。在上述方法中，将第一区域111划分为多个第一补偿单元，然后第一区域111以第一补偿单元为最小单元确定对应的第一补偿参数。采用这种方式可以大大减小需要存储的数据量，从而降低成本。例如，第一区域111还可以不划分第一补偿单元，而直接采用第一像素单元为最小单元确定第一补偿参数，采用这种方式需要存储的数据量较大，但补偿效果会更好，即可以更好地改善显示不均等显示不良问题。
例如，第二区域112被划分为多个第二补偿单元(或像素单元组)，第二补偿单元包括一组像素单元，该像素单元组包括至少一个第二像素单元，上述按照第二目标区域TG2的亮度确定第二补偿参数包括如下操作步骤。
步骤S210：根据显示面板自身的伽玛曲线获得每个第二补偿单元的亮度数据对应的灰阶数据，每个第二补偿单元根据第二目标区域对应的灰阶数据确定对应的第二补偿参数。
例如，在上述步骤S210中，可以根据显示面板的伽玛曲线将亮度数据转换为对应的灰阶数据，然后根据灰阶数据获得每个第二补偿单元对应的第二补偿参数。
例如，每个第二补偿单元包括4行4列第二像素单元，本公开的实施例包括但不限于此，该第二补偿单元还可以包括更多或更少个第二像素单元。在上述方法中，将第二区域112划分为多个第二补偿单元，然后第二区域112以第二补偿单元为最小单元确定对应的第二补偿参数。采用这种方式可以大大减小需要存储的数据量，从而降低成本。例如，第二区域112还可以不划分第二补偿单元，而直接采用第二像素单元为最小单元确定第二补偿参数，采用这种方式需要存储的数据量较大，但补偿效果会更好，即可以更好地改 善显示不均等显示不良问题。
例如，在本公开的一些实施例提供的亮度补偿参数检测方法中，第一补偿单元和第二补偿单元大小相等。即第一区域111和第二区域112进行亮度补偿的最小单元相等，采用这种方式在一定程度可以进一步改善显示不均等显示不良问题。
在本公开的一些实施例提供的亮度补偿参数检测方法中，上述第一补偿单元根据第一目标区域TG1对应的灰阶数据确定对应的第一补偿参数包括如下操作步骤。
步骤S111：向第一区域111输入第一灰阶值的单色图像；例如，当灰阶值依然采用上述8比特(0～255共256个灰阶值)的数据表示时，则最高灰阶值为255，例如，第一灰阶值可以采用最高灰阶值的1/8，约为31。需要说明的是，本公开的实施例对第一灰阶值的选择不作限定。
步骤S112：获取此时第一区域111中的所有第一像素单元的亮度数据集合并记为第一亮度数据，并根据第一亮度数据获得第一目标区域的第一目标亮度值YG 1，第一目标亮度值YG 1为第一目标区域中的所有第一像素单元的亮度数据的平均值；根据第一亮度数据获得第一补偿单元的第一原始亮度值XG 1，第一原始亮度值XG 1为第一补偿单元中的所有第一像素单元的亮度数据的平均值。例如，在向第一区域111输入第一灰阶值(例如为31)的单色图像时(理想状态下第一区域111中的全部第一像素单元会显示相同的亮度)，获取第一区域111中的所有第一像素单元的亮度数据集合并记为第一亮度数据。
例如，在一些实施例中，可以采用图像采集装置对显示面板进行拍照以获得第一图像数据，然后根据第一图像数据以及该图像采集装置的配置参数获取第一亮度数据。例如，该图像采集装置的分辨率可以高于显示面板的分辨率。例如，该图像采集装置对显示面板进行拍照获得第一图像数据，该第一图像数据包括显示面板发光的亮度信息，再结合该图像采集装置的配置参数即可以获取第一亮度数据。例如，该图像采集装置可以采用CMOS相机或CCD相机等。当该照相机的配置参数(例如，曝光时间)改变时，所获得的第一图像数据也会不同，所以要结合图像采集装置的配置参数从第一图像数据中将第一亮度数据提取出来。
在获得第一亮度数据后，可以根据第一亮度数据与显示面板的对应关系，对每个第一补偿单元中的所有第一像素单元的亮度数据取平均值从而获得对应每个第一补偿单元的第一原始亮度值XG 1；相应地，对第一目标区域TG 1中的所有第一像素单元的亮度数据取平均值从而获得第一目标亮度值YG 1。需要说明的是，本公开的实施例包括但不限于此，例如，也可以对每个第一补偿单元中的所有第一像素单元的亮度数据取最大值(或取平均值的某一比例值)从而获得对应每个第一补偿单元的第一原始亮度值XG 1；相应地，对第一目标区域TG1中的所有第一像素单元的亮度数据取最大值(或取平均值的某一比例值)从而获得第一目标亮度值YG 1。
步骤S113：根据伽玛曲线获得对应于第一目标亮度值YG 1的第一目标灰阶值Y 1，以及根据伽玛曲线获得对应于第一原始亮度值XG 1的第一原始灰阶值X 1。例如，显示面板的伽玛曲线可以采用图4中所示的伽玛曲线，在获得第一目标亮度值YG 1和第一原始亮度值XG 1后，可以通过计算获得对应的透过率(透过率等于亮度与最大亮度的比值)，然后再根据伽玛曲线获得对应的灰阶值。
步骤S114：向第一区域111输入第二灰阶值的单色图像；例如，第二灰阶值可以采用最高灰阶值的7/8，约为223。需要说明的是，本公开的实施例对第二灰阶值的选择不作限定。在本公开的实施例中，第一灰阶值和第二灰阶值的选取可以根据需要进行选择，只要第一灰阶值和第二灰阶值不相同即可。例如，第一灰阶值可以选取一个相对较小的灰阶值，而第二灰阶值可以选取一个相对较大的灰阶值，从而可以使得在计算补偿参数时可以覆盖不同区间的亮度，从而可以更好地改善亮度不均等显示不良问题。
步骤S115：获取此时第一区域111中的所有第一像素单元的亮度数据集合并记为第二亮度数据，并根据第二亮度数据获得第一目标区域TG1的第二目标亮度值YG 2，第二目标亮度值YG 2为第一目标区域中的所有第一像素单元的亮度数据的平均值；根据第二亮度数据获得第一补偿单元的第二原始亮度值XG 2，第二原始亮度值XG 2为第一补偿单元中的所有第一像素单元的亮度数据的平均值。关于该步骤S115和上述步骤S112类似，这里不再赘述。
步骤S116：根据伽玛曲线获得对应于第二目标亮度值YG 2的第二目标灰阶值Y 2，以及根据伽玛曲线获得对应于第二原始亮度值XG 2的第二原始灰阶 值X 2。
步骤S117：按照如下方程组计算获得对应于第一补偿单元的第一补偿增益值A 1和第一补偿偏差值B 1：
A 1*X 1+B 1＝Y 1，A 1*X 2+B 1＝Y 2；
第一补偿参数包括第一补偿增益值A 1和第一补偿偏差值B 1。
需要说明的是，经过上述步骤获得的是对应于一个第一补偿单元的第一补偿参数(第一补偿增益值A 1和第一补偿偏差值B 1)，对于第一区域111中的其它第一补偿单元可以采用和上述相同的方法获得对应的第一补偿参数。例如，厂家端在制造完显示面板后可以在对该显示面板的质检过程中实施上述亮度补偿参数检测方法，例如，获得的对应于第一区域111中的每个第一补偿单元的第一补偿参数可以存储在存储器中。然后，例如当在用户端使用该显示面板时，可以直接从该存储器中调用上述第一补偿参数，从而完成对该显示面板的亮度补偿，从而可以改善或避免显示不均等显示不良问题。
在本公开的一些实施例提供的亮度补偿参数检测方法中，上述第二补偿单元根据第二目标区域TG2对应的灰阶数据确定对应的第二补偿参数包括如下操作步骤。
步骤S211：向第二区域输入第一灰阶值的单色图像；例如，在一些实施例中，该步骤S211和上述步骤S111可以同时进行，即同时向显示面板(包括第一区域111和第二区域112)输入第一灰阶值的单色图像，采用这种方式可以简化亮度补偿参数检测方法。
步骤S212：获取此时第二区域112中的所有第二像素单元的亮度数据集合并记为第三亮度数据，并根据第三亮度数据获得第二目标区域TG2的第三目标亮度值YG 3，第三目标亮度值YG 3为第二目标区域中的所有第二像素单元的亮度数据的平均值；根据第三亮度数据获得第二补偿单元的第三原始亮度值XG 3，第三原始亮度值XG 3为第二补偿单元中的所有第二像素单元的亮度数据的平均值；关于该步骤S212和上述步骤S112类似，这里不再赘述。
步骤S213：根据伽玛曲线获得对应于第三目标亮度值YG 3的第三目标灰阶值Y 3，以及根据伽玛曲线获得对应于第三原始亮度值XG 3的第三原始灰阶值X 3。
步骤S214：向第二区域112输入第二灰阶值的单色图像；例如，在一些 实施例中，该步骤S214和上述步骤S114可以同时进行，即同时向显示面板(包括第一区域111和第二区域112)输入第二灰阶值的单色图像，采用这种方法可以简化该亮度补偿参数检测方法。
步骤S215：获取此时第二区域112中的所有第二像素单元的亮度数据集合并记为第四亮度数据，并根据第四亮度数据获得第二目标区域TG2的第四目标亮度值YG 4，第四目标亮度值YG 4为第二目标区域中的所有第二像素单元的亮度数据的平均值；根据第四亮度数据获得第二补偿单元的第四原始亮度值XG 4，第四原始亮度值XG 4为第二补偿单元中的所有第二像素单元的亮度数据的平均值。
步骤S216：根据伽玛曲线获得对应于第四目标亮度值YG 4的第四目标灰阶值Y 4，以及根据伽玛曲线获得对应于第四原始亮度值XG 4的第四原始灰阶值X 4。
步骤S217：按照如下方程组计算获得对应于第二补偿单元的第二补偿增益值A 2和第二补偿偏差值B 2：
A 2*X 3+B 2＝Y 3，A 2*X 4+B 2＝Y 4；
第二补偿参数包括第二补偿增益值A 2和第二补偿偏差值B 2。
需要说明的是，经过上述步骤获得的是对应于一个第二补偿单元的第二补偿参数(第二补偿增益值A 2和第二补偿偏差值B 2)，对于第二区域112中的其它第二补偿单元可以采用和上述相同的方法获得对应的第二补偿参数。例如，厂家端在制造完显示面板后可以在对该显示面板的质检过程中实施上述亮度补偿参数检测方法，例如，获得的对应于第二区域112中的每个第二补偿单元的第二补偿参数可以存储在存储器中。然后，例如当在用户端使用该显示面板时，可以直接从该存储器中调用上述第二补偿参数，从而完成对该显示面板的亮度补偿，从而可以改善或避免显示不均等显示不良问题。
例如，图3为图2中的显示面板进行显示时位于不同位置处的亮度变化曲线。如图3所示，横坐标表示该显示面板的行数，例如，该显示面板包括3120行像素单元，纵坐标表示对应位置处的亮度。例如，当采用上述亮度补偿参数检测方法时，第一目标区域TG1可以选取第一区域111中包括亮度最低的第一像素单元的区域，第二目标区域TG2可以选取包括第二区域112中位于中心位置处的第二像素单元的区域。当然，本公开的实施例对第一目标 区域TG1和第二目标区域TG2的选取不作限定。
本公开的一些实施例提供的亮度补偿参数检测方法还包括如下操作步骤。
步骤S120：在获得第一亮度数据后，对第一亮度数据进行滤波以消除噪声。
步骤S220：在获得第二亮度数据后，对第二亮度数据进行滤波以消除噪声。
例如，对第一亮度数据进行滤波可以消除噪声，例如，可以滤除数据异常的点。例如，可以采用低通滤波器执行步骤S120，类似地，可以采用低通滤波器执行步骤S220。需要说明的是，可以采用本领域的常规方式进行滤波，本公开的实施例对此不作限定。
本公开的一些实施例提供的亮度补偿参数检测方法通过对第一亮度数据和第二亮度数据进行滤波，可以避免数据异常的点对补偿参数计算造成的影响，从而可以进一步提高亮度补偿的效果。
本公开的至少一实施例还提供用于用户端的亮度补偿方法，例如，该亮度补偿方法可以对显示面板的亮度进行补偿。例如，图2示出了一种显示面板，该显示面板的显示区域包括第一区域111和第二区域112，第一区域111包括按照第一阵列排布的多个第一像素单元，第二区域112包括按照第二阵列排布的多个第二像素单元，第一区域111和第二区域112为不同区域。例如，如图2所示，该显示面板可以是包括“刘海区”120的OLED显示面板。例如，第一区域111为靠近“刘海区”120的区域，第二区域112为该显示面板的显示区域中除了第一区域111外的其它区域。例如，该显示面板的第一区域111和第二区域112是用于显示图像的区域，“刘海区”120中一般设置有例如摄像头、传感器等器件，该“刘海区”120一般不用于显示图像。
例如，该亮度补偿方法包括如下操作步骤。
步骤S300：第一区域111中的至少部分第一像素单元按照第一补偿参数进行亮度补偿。例如，第一补偿参数是基于第一目标区域TG1的亮度确定的，第一区域111包括第一目标区域TG1。
步骤S400：第二区域112中的至少部分第二像素单元按照第二补偿参数进行亮度补偿。例如，第二补偿参数是基于第二目标区域TG2的亮度确定的， 第二区域112包括第二目标区域TG2。
在本公开的一些实施例提供的亮度补偿方法中，例如，第一区域111被划分为多个第一补偿单元，则上述步骤S300包括如下操作步骤。
步骤S310：第一区域111以第一补偿单元为最小单元，按照第一补偿参数进行亮度补偿。例如，将第一区域111划分为多个第一补偿单元(或像素单元组)，然后第一区域111以第一补偿单元为最小单元按照对应的第一补偿参数进行亮度补偿。采用这种方式可以大大减小需要存储的数据量，从而降低成本。例如，第一区域111还可以不划分第一补偿单元，而直接采用第一像素单元为最小单元进行亮度补偿，采用这种方式需要存储的数据量较大，但补偿效果会更好，即可以更好地改善显示不均等显示不良问题。
例如，第二区域112被划分为多个第二补偿单元，则上述步骤S400包括如下操作步骤。
步骤S410：第二区域112以第二补偿单元为最小单元，按照第二补偿参数进行亮度补偿。例如，将第二区域112划分为多个第二补偿单元(或像素单元组)，然后第二区域112以第二补偿单元为最小单元按照对应的第二补偿参数进行亮度补偿。采用这种方式可以大大减小需要存储的数据量，从而降低成本。例如，第二区域112还可以不划分第二补偿单元，而直接采用第二像素单元为最小单元进行亮度补偿，采用这种方式需要存储的数据量较大，但补偿效果会更好，即可以更好地改善显示不均等显示不良问题。
在本公开的一些实施例提供的亮度补偿方法中，例如，第一补偿参数包括第一补偿增益值A 1和第一补偿偏差值B 1；对第一补偿单元中的第一像素单元的亮度按照如下方程进行补偿：
A 1*X O1+B 1＝Y A1；
X O1为第一补偿单元中的第一像素单元被补偿前的灰阶值，Y A1为第一补偿单元中的第一像素单元被补偿后的灰阶值。
例如，第二补偿参数包括第二补偿增益值A 2和第二补偿偏差值B 2；对第二补偿单元中的像素单元的亮度按照如下方程进行补偿：
A 2*X O2+B 2＝Y A2；
X O2为第二补偿单元中的第二像素单元被补偿前的灰阶值，Y A2为第二补偿单元中的第二像素单元被补偿后的灰阶值。
关于第一补偿增益值A 1、第一补偿偏差值B 1、第二补偿增益值A 2和第二补偿偏差值B 2可以参考上述实施例中的相应描述，这里不再赘述。
例如，厂家端在制造完显示面板后可以在对该显示面板的质检过程中获得对应于第一区域111中的每个第一补偿单元的第一补偿参数，以及对应于第二区域112中的每个第二补偿单元的第二补偿参数。然后，上述第一补偿参数和第二补偿参数可以存储在存储器中，例如，当在用户端使用该显示面板时，可以直接从该存储器中调用上述第一补偿参数和第二补偿参数，从而完成对该显示面板的亮度补偿，从而可以改善或避免显示不均等显示不良问题。
本公开的至少一实施例还提供一种亮度补偿参数检测装置200，该亮度补偿参数检测装置200可以用于对显示面板的亮度进行补偿。例如，图2示出了一种显示面板，该显示面板的显示区域包括第一区域111和第二区域112，第一区域111包括按照第一阵列排布的多个第一像素单元，第二区域112包括按照第二阵列排布的多个第二像素单元，第一区域111和第二区域112为不同区域。例如，如图5所示，该亮度补偿参数检测装置200包括二维目标计算单元210以及补偿参数计算单元220。
例如，该二维目标计算单元210被配置为从第一区域111中选取第一目标区域TG1，且从第二区域112中选择第二目标区域TG2。关于第一目标区域TG1和第二目标区域TG2的描述可以参考上述关于亮度补偿参数检测方法的实施例中的相应描述，这里不再赘述。
例如，补偿参数计算单元220被配置为按照第一目标区域TG1的亮度确定第一补偿参数，以用于第一区域111中的至少部分第一像素单元按照第一补偿参数进行亮度补偿，以及被配置为按照第二目标区域TG2的亮度确定第二补偿参数，以用于第二区域112中的至少部分第二像素单元按照第二补偿参数进行亮度补偿。
本公开的一些实施例提供的亮度补偿参数检测装置200可以针对第一区域111和第二区域112分别获取第一补偿参数和第二补偿参数，例如，该第一补偿参数和第二补偿参数可以提供至显示面板的驱动电路，该驱动电路在驱动显示面板进行显示操作时可以利用上述第一补偿参数和第二补偿参数对显示面板的发光亮度进行补偿，从而可以改善或避免显示面板的亮度不均等 显示不良问题。
例如，第一区域111被划分为多个第一补偿单元(或像素单元组)，第一补偿单元包括至少一个第一像素单元，二维目标计算单元210被配置为根据显示面板自身的伽玛曲线获得每个第一补偿单元的亮度数据对应的灰阶数据，补偿参数计算单元220被配置为根据第一目标区域TG1对应的灰阶数据确定每个第一补偿单元对应的第一补偿参数。
