具体实施方式
下面将详细描述本申请的各个方面的特征和示例性实施例，为了使本申请的目的、技术方案及优点更加清楚明白，以下结合附图及具体实施例，对本申请进行进一步详细描述。应理解，此处所描述的具体实施例仅被配置为解释本申请，并不被配置为限定本申请。对于本领域技术人员来说，本申请可以在不需要这些具体细节中的一些细节的情况下实施。下面对实施例的描述仅仅是为了通过示出本申请的示例来提供对本申请更好的理解。
需要说明的是，在本文中，诸如第一和第二等之类的关系术语仅仅用来将一个实体或者操作与另一个实体或操作区分开来，而不一定要求或者暗示这些实体或操作之间存在任何这种实际的关系或者顺序。而且，术语“包括”、“包含”或者其任何其他变体意在涵盖非排他性的包含，从而使得包括一系列要素的过程、方法、物品或者设备不仅包括那些要素，而且还包括没有明确列出的其他要素，或者是还包括为这种过程、方法、物 品或者设备所固有的要素。在没有更多限制的情况下，由语句“包括……”限定的要素，并不排除在包括所述要素的过程、方法、物品或者设备中还存在另外的相同要素。
应当理解，本文中使用的术语“和/或”仅仅是一种描述关联对象的关联关系，表示可以存在三种关系，例如，A和/或B，可以表示：单独存在A，同时存在A和B，单独存在B这三种情况。另外，本文中字符“/”，一般表示前后关联对象是一种“或”的关系。
在不脱离本申请的精神或范围的情况下，在本申请中能进行各种修改和变化，这对于本领域技术人员来说是显而易见的。因而，本申请意在覆盖落入所对应权利要求(要求保护的技术方案)及其等同物范围内的本申请的修改和变化。需要说明的是，本申请实施例所提供的实施方式，在不矛盾的情况下可以相互组合。
在阐述本申请实施例所提供的技术方案之前，为了便于对本申请实施例理解，本申请首先对相关技术中存在的问题进行具体说明：
有机发光二极管(Organic Light Emitting Diode，OLED)显示面板具有自发光、反应快、亮度高、轻薄等诸多优点，已经逐渐成为显示领域的主流。OLED显示面板以电流驱动显示，其由驱动芯片(IC)端开始并通过电源走线(ELVDD走线)向子像素提供电压。而ELVDD走线必然存在一定阻抗，导致不同位置的子像素的实际电流于其理论电流存在一定差异，进而影响显示面板的亮度均匀性。
发明人研究发现，除了常规的情况，比如靠近IC侧的子像素偏亮远离IC侧的子像素偏暗，显示面板会出现一些非常规的亮度趋势，例如左亮右暗、上亮下暗、对角一亮一暗等，而相关技术中对非常规的亮度趋势，无法达到预期的均一性补偿效果，甚至出现弱化补偿显示均一性或逆补偿显示均一性的情况，进而影响均一性补偿效果。
为解决上述问题，本申请实施例提供了一种亮度补偿方法、装置、设备及介质，以下将结合附图对亮度补偿方法、装置、设备及介质的各实施例进行说明。
如图1所示，本申请实施例提供的亮度补偿方法包括步骤S10～S40。
S10，在显示面板的显示区设置多个第一锚点以及至少一个固定锚点；
S20，将显示面板的显示区划分为多个调整区，每个调整区包括至少一个第一锚点，确定每个调整区在待补偿灰阶画面下的第一补偿增益；
S30，根据第一锚点对应的亮度值、固定锚点对应的亮度值以及第一锚点所属的调整区的第一补偿增益，确定第一锚点对应的第二补偿增益；
S40，根据第二补偿增益，对第一锚点对应的像素进行亮度补偿。
上述步骤S10～S40的具体实现方式将在下文中进行详细描述。
根据本申请实施例提供的亮度补偿方法，通过设置多个第一锚点和至少一个固定锚点，相当于对待补偿灰阶画面进行了分割处理，并且不仅确定了调整区的第一补偿增益，又进一步基于第一补偿增益确定第一锚点对应的第二补偿增益，从而可实现动态调整第一锚点对应的增益，如此能够对不同亮度趋势，包括非常规的亮度趋势，实现准确高效、精细化的高目标的均一性补偿，进而提升显示面板的显示均一性。
下面介绍上述各个步骤的具体实现方式。
首先介绍S10。
可理解的是，第一锚点对应的第二补偿增益可动态调整。固定锚点对应的补偿增益可为恒定增益，固定锚点对应的补偿增益可不随补偿算法的变化而发生改变。例如，可根据实际需求确定固定锚点对应的补偿增益。
示例性的，第一锚点可位于显示区的边缘，多个第一锚点可包围固定锚点。这样，固定锚点大致位于显示区的中间位置。多个第一锚点包围固定锚点的情况下，由于固定锚点对应的补偿增益可为恒定增益，第一锚点对应的第二补偿增益可动态调整，也就是可调整显示区边缘的亮度，例如将显示区边缘的亮度向上拉或者向下拉，并使边缘的亮度与中间的亮度区域一致。
作为一个示例，多个第一锚点可在显示区的边缘均匀分布。显示区的拐角处可设置有第一锚点，例如显示区为矩形，则显示区的四个角落均可设置有第一锚点。
示例性的，多个第一锚点和至少一个固定锚点整体上可均匀分布于显示区。
例如，可根据显示区的形状及尺寸设置第一锚点及固定锚点。作为一个示例，如图2所示，以显示区AA为矩形为例，可设置12个第一锚点和4个固定锚点，12个第一锚点和4个固定锚点可将显示区划分为3行3列共计9个分区。其中，P11、P12、P13、P14、P21、P24、P31、P34、P41、P42、P43、P44表示第一锚点，P22、P23、P32、P33表示固定锚点。
第2行第2列也就是中心位置的分区可由四个固定锚点围合而成。当然，也可设置更多说了的第一锚点和/或更多数量的固定锚点。第一锚点的数量越多，则补偿精度越高。
接着介绍S20。
在一些可选的实施例中，如图3所示，S20具体可以包括S21～S22。
S21，将显示面板的显示区划分为多个调整区，每个调整区包括至少一个第一锚点，确定每个调整区在待补偿灰阶画面下的第一亮度代表值；
S22，根据第一亮度代表值及调整区对应的目标亮度值，确定调整区的第一补偿增益。
示例性的，第一亮度代表值可代表调整区的亮度趋势。例如，第一亮度代表值可代表调整区偏亮或者偏暗。
上述S21～S22的具体实现方式将在下文中进行详细描述。
根据本申请实施例，第一亮度代表值能够表征调整区的亮度趋势，因此根据第一亮度代表值所确定的第一补偿增益更准确。
在一些可选的实施例中，如图4所示，S21具体可以包括S211～S214。
S211，根据预设的多个第二锚点，将显示面板的显示区划分为多个第二分区，其中，多个第一锚点以及至少一个所述固定锚点将显示面板的显示区分为多个第一分区，每个第一分区包括至少一个第二分区；
S212，将多个第二分区划分为多个调整区，每个调整区包括至少一个第一分区；
S213，在待补偿灰阶画面下，获取每个第二分区中的多个像素的亮度，并确定每个第二分区的第二亮度代表值；
S214，根据调整区中的第二分区的第二亮度代表值，确定调整区在待补偿灰阶画面下的第一亮度代表值。
上述S211～S214的具体实现方式将在下文中进行详细描述。
根据本申请实施例，多个第二锚点将显示区划分为多个第二分区，且每个第一分区包括至少一个第二分区，每个调整区包括至少一个第一分区，并基于第二分区的第二亮度代表值确定调整区的第一亮度代表值，这样采用分区形式分割待补偿灰阶画面，调整区内第二分区的第二亮度代表值可表征调整区的亮度分布规律，如此可提升表征调整区亮度区域的第一亮度代表值的准确性及代表性。
在S211中，预设的第二锚点的数量可远大于第一锚点的数量。第二锚点的数量越多，则所确定的第二亮度代表值越具有代表性，进而第一亮度代表值也越准确且越具有代表性。
多个第二锚点可以均匀分布于显示区。例如，多个第二锚点可以呈行列分布。
作为一个示例，如图5所示，其中，圆形实心点表示第一锚点、三角形实心点表示固定锚点，方形实心填充表示第二锚点，例如第二锚点可为135个，例如可按照9列(V)15行(H)的方式划分显示区，这样得到135个第二分区。为了区分各个区域，本文中将第一分区标记为A1，第二分区标记为A2。部分第二锚点的位置可以和第一锚点的位置重叠，部分第二锚点的位置可以和固定锚点的位置重叠。每个第一分区A1可包括5行3列共计15个第二分区A2。
本文附图中，以第一分区、第二分区、调整区均为矩形示意，这些区域也可以为其它形状，本申请对此不作限定。
在S212中，调整区可理解为亮度需要调整的区域。可根据经验划分调整区。例如，以靠近IC侧的区域为下区域，可根据亮度趋势，按照上中下的方式划分调整区，例如可将上区域及下区域划分为调整区。又例如，在上区域的左右两侧呈现不同的亮度趋势的情况下，可进一步将上区域按照左右的方式进行划分，例如，可将上区域的左区域及右区域进一步划分为两个调整区。作为一个示例，可根据各第二分区的亮度，确定每个第一分区的亮度趋势，然后根据每个第一分区的亮度趋势划分调整区。上述仅仅是一些示例，并不用于限定本申请。
例如，调整区可包括至少一个第一分区A1。另外，调整区包括至少一个第一锚点，且调整区可不包括固定锚点。
作为一个示例，参考图2，可将显示区AA划分为三个调整区，分别为调整区AT1、调整区AT2、调整区AT3。第一锚点可包括P11、P12、P13、P14、P21、P24、P31、P34、P41、P42、P43、P44，固定锚点可包括P22、P23、P32、P33。其中，调整区AT1可包括第一锚点P11、P12、P21，调整区AT2可包括第一锚点P13、P14、P24，调整区AT3可包括第一锚点P31、P34、P41、P42、P43、P44。
在S213中，待补偿灰阶画面可为任意一个灰阶画面。例如，显示面板可显示0～255灰阶，待补偿灰阶画面可为任意一个灰阶的白色画面或者任意一个灰阶的单色画面。以白色画面为例，则获取的第二分区中像素的亮度可包括各颜色的子像素的亮度，进而可确定第一锚点所对应的各颜色的子像素的第二补偿增益。
在一些可选的实施例中，如图6所示，S213具体可以包括S2131和S2132。
S2131，在待补偿灰阶画面下，获取每个第二分区中的多个像素的亮度，并确定每个第二分区的亮度分布规律；
S2132，根据每个第二分区的亮度分布规律，确定每个第二分区的第二亮度代表值。
本申请实施例中，第二分区的第二亮度代表值是根据其亮度分布规律确定的，如此可提高第二亮度代表值准确性以及代表性。
示例性的，以显示区包括1080*2400个像素为例，按照9列(V)15行(H)的方式，多个第二锚点可将显示区划分为135个第二分区，每个第二分区内可包括120*160个像素。例如在待补偿灰阶画面下，可获取每个第二分区中的多个像素的亮度值，统计每个亮度值出现的数量，然后根据每个亮度值出现的数量为每个亮度值设置权重，以每个亮度值及其权重作为每个第二分区的亮度分布规律。
例如，可以用关系式(1)表征第二分区的亮度分布规律：
P{X＝x k}＝p k，k＝1,2,3,4,5.......n    (1)
其中，x k表示亮度值，p k表示亮度值x k对应的权重，n表示亮度值的数量。
进一步的，可对第二分区的各像素的亮度进行加权求和，将加权和作为第二分区的第二亮度代表值。
例如，可以用关系式(2)计算第二分区的第二亮度代表值：
Figure PCTCN2022121913-appb-000001
其中，G i(X)第二分区的第二亮度代表值。
为了更好的理解如何确定第二亮度代表值，下面举一个示例，例如，第二分区内共计10个像素，其中3个像素的亮度值均为L1，5个像素的亮度值均为L2，2个像素的亮度值均为L3，则亮度值L1的权重可以为3/10，亮度值L2的权重可以为5/10，亮度值L3的权重可以为2/10，该第二分区的第二亮度代表值等于0.3*L1+0.5*L2+0.2*L3。
上述仅仅是一个示例，并不用于限定本申请。例如，可以将第二分区内多个像素的亮度均值作为第二分区的第二亮度代表值。
在一些可选的实施例中，调整区包括多个第二分区，如图7所示，S214具体可以包括S2141和S2142。
S2141，在调整区中的多个第二分区中选取一个第二分区作为目标区，并使选取的目标区与调整区中的其它第二分区的距离小于或等于第一阈值；
S2142，将选取的目标区的第二亮度代表值，作为调整区在待补偿灰阶画面下的第一亮度代表值。
本申请实施例中，由于选取的目标区与调整区中的其它第二分区的距离小于或等于第一阈值，可以理解为，目标区与调整区中的其它第二分区的路径是最短的，这样目标区对应的第二亮度代表值更能代表调整区的亮度趋势。
可以根据实际需求设置第一阈值的具体数值，本申请对此不作限定。
作为一个示例，如图8所示，S2141具体可以包括S21411～S21415。
S21411，在调整区中的多个第二分区中选取一个第二分区作为待定区；
S21412，计算待定区与调整区中的其它第二分区的第一距离；
S21413，判断多个第一距离中的最大距离是否小于或等于第一阈值；
S21414，若是，则将待定区作为目标区；
S21415，若否，则重新选取一个第二分区作为待定区，并计算重新选取的待定区与调整区中的其它未被选取过的第二分区的第二距离，直至多个第二距离中的最大距离小于或等于第一阈值，将重新选取的待定区作为目标区。
本申请实施例中，不再计算重新选取的待定区与已经被选取过的第二分区的第二距离，也就是在已经被选取过的第二分区不符合要求的情况下，逐步剔除已经被选取过的第二分区，这样可以减少计算量，提升补偿算法数据处理运算效率，且能按照最短路径选取出符合要求的目标区。
在S21411中，可在调整区中的多个第二分区中随意选取一个第二分区作为待定区，本申请对此不作限定。
在S21412中，可以确定每个第二分区的代表坐标值。例如，可将第二分区的中心点的坐标作为第二分区的代表坐标值，然后计算待定区的中心点与调整区中的其它各个第二分区的中心点之间的第一距离。例如，调整区内有10个第二分区，可从10个中选取一个作为待定区，然后计算待定区与其它9个中的每一个第二分区的第一距离。
在S21413中，仍以调整区内有10个第二分区为例，则需要判断计算得到的9个第一距离中的最大距离是否小于或等于第一阈值。示例性的，多个第一距离中部分数值可能是相同的，这并不影响待定区的选取。
在S21414中，若最大的第一距离都小于或等于第一阈值的话，则其它第一距离也都小于或等于第一阈值，这样选择的待定区到每个第二分区的路径整体上是最短的，从而该待定区可作为目标区。
示例性的，S21415中重新选取一个第二分区作为待定区，具体可以包括：计算调整区中的其它未被选取过的第二分区的坐标均值，将坐标均值对应的第二分区作为重新选取的待定区。这样可以快速的确定符合要求的待定区。
可理解的是，在选取待定区的过程中，可能要执行多次选取。例如，仍以调整区内有10个第二分区，在第一次选取的待定区不符合要求的情况下，则执行第二次选取，可在其它9个第二分区中选取一个作为待定区， 并计算待定区与其它8个未被选取过的第二分区的第二距离；在第一次选取的待定区不符合要求的情况下，则执行第三次选取，可在其它8个第二分区中选取一个作为待定区，并计算待定区与其它7个未被选取过的第二分区的第二距离；如此依次执行选取步骤。
为了更好的理解待定区的选取过程，举一个示例，如图9所示，调整区包括8行8列共计64个第二分区，随机选取第二分区G62作为待定区，然后计算第二分区G62分别与第一数据集合(第一数据集合包括第二分区G1至第二分区G64，不包括第二分区G62)的第一距离，共计63个第一距离。进一步的，将63个第一距离中的最大距离与第一阈值比较。若63个第一距离中的最大距离小于或等于第一阈值，则将第二分区G62作为目标区。若63个第一距离中的最大距离大于第一阈值，则计算第一数据集合的坐标均值，其坐标均值对应的第二分区作为待定区，例如第一数据集合的坐标均值对应第二分区G28，第二分区G28即为重新选取的待定区。然后计算第二分区G28与第二数据集合(第二数据集合包括第二分区G1至第二分区G64，不包括第二分区G28及第二分区G62)的第二距离，共计62个第二距离。同理，62个第二距离中的最大距离与第一阈值比较。若第二分区G28不符合要求，则计算第二数据集合的坐标均值，重复上述重新确定待定区及计算第二距离的步骤。
上述确定目标区的方式仅仅是一个示例，也可以按照其它方式确定目标区，例如可以选取调整区内中心位置处的第二分区作为目标区。
接着介绍S22。
在一些可选的实施例中，如图10所示，S22具体可以包括S221。
S221，计算第一亮度代表值与调整区对应的目标亮度值的第一比值，得到调整区的第一补偿增益。
本申请实施例可以快速确定调整区的第一补偿增益。
作为一个示例，目标亮度值可以包括显示区的中心区域在待补偿灰阶画面下的亮度均值。多个调整区对应的目标亮度值可以相同。
例如，如图11所示，可将显示区AA划分为固定区AN以及多个调整区，例如调整区AT1、AT2、AT3，其中，固定区AN可位于显示区的中 间，调整区AT1、AT2、AT3位于固定区AN的两侧。
例如，调整区AT1的第一亮度代表值为G 1x，调整区AT2的第一亮度代表值为G 2x，调整区AT3的第一亮度代表值为G nx，固定区AN的亮度均值为G，则调整区AT1的第一补偿增益Gain 1x＝G 1x/G，调整区AT2的第一补偿增益Gain 2x＝G 2x/G，调整区AT3的第一补偿增益Gain nx＝G nx/G。
作为另一个示例，目标亮度值包括待补偿灰阶画面对应的需求亮度值。例如，待补偿灰阶画面为255灰阶画面，则可在预设的伽马曲线中，确定255灰阶对应的亮度值，将255灰阶对应的亮度值作为目标亮度值。
作为又一个示例，固定锚点的数量可包括至少三个，多个固定锚点围合呈固定区域，目标亮度值可包括固定区域在待补偿灰阶画面下的亮度均值。例如，如图2所示，固定锚点P22、P23、P32、P33围合的区域在待补偿灰阶画面下的亮度均值可作为目标亮度值。
上述仅仅是一些示例，也可以根据其它方式确定目标亮度值，本申请对此不作限定。
接着介绍S30。
在一些可选的实施例中，如图12所示，S30具体可以包括S31～S32。
S31，计算第一锚点对应的亮度值与固定锚点对应的亮度值的第二比值；
S32，计算第二比值与第一锚点所属的调整区的第一补偿增益的乘积，得到第一锚点对应的第二补偿增益。
本申请实施例可以快速、准确地确定第一锚点的第二补偿增益。
作为一个示例，第一锚点对应的亮度值可包括第一锚点所在位置的像素的亮度值，固定锚点对应的亮度值可包括固定锚点所在位置的像素的亮度值。第一锚点所在位置的像素可包括一个或多个像素，固定锚点所在位置的像素可包括一个或多个像素。
作为另一个示例，第一锚点对应的亮度值可包括第一锚点所在区域内的像素的亮度均值，固定锚点对应的亮度值包括固定锚点所在区域内的像素的亮度均值。例如，可以第一锚点为中心，并根据第一预设半径确定第一锚点所在区域；以固定锚点为中心，并根据第二预设半径确定固定锚点 所在区域。可根据实际需求设置第一预设半径和第二预设半径。多个第一锚点对应的第一预设半径可以相同，多个固定锚点对应的第二预设半径可以相同。
作为又一个示例，固定锚点对应的亮度值可包括预设值，第一锚点对应的亮度值可包括预设值与预设系数的乘积。可根据实际需求设置预设值和预设系数。例如，预设值可为固定锚点所能够达到的期望的亮度值，预设值与预设系数的乘积可为第一锚点所能够达到的期望的亮度值。
示例性的，在S31中，第一锚点与固定锚点可以相邻。例如，如图2所示，固定锚点P22与第一锚点P11、P12、P21相邻，固定锚点P23与第一锚点P13、P14、P24相邻，固定锚点P32与第一锚点P31、P41、P42相邻，固定锚点P33与第一锚点P34、P43、P44相邻。
示例性的，在S32中，可将乘积作为第一锚点对应的第二补偿增益。例如，第一锚点P11对应的第二补偿增益可等于Gain 1x*L 11/L 22，第一锚点P13对应的第二补偿增益可等于Gain 2x*L 13/L 23，第一锚点P31对应的第二补偿增益可等于Gain nx*L 31/L 32，其它同理。其中，L 11表示第一锚点P11对应的亮度值，L 22表示固定锚点P22对应的亮度值，L 13表示第一锚点P13对应的亮度值，L 23表示固定锚点P23对应的亮度值,L 31表示第一锚点P31对应的亮度值，L 32表示固定锚点P32对应的亮度值。如此可计算每个第一锚点对应的第二补偿增益。
接着介绍S40。
示例性的，本文中第一补偿增益、第二补偿增益可为亮度对应的增益。例如，可获取第一锚点对应的像素的初始亮度，然后计算初始亮度与第二补偿增益的乘积，将该乘积作为第一锚点对应的像素要显示的亮度。
示例性的，可以利用插值的方式确定第一锚点之外的其它位置处的像素对应的补偿增益，例如可以根据第一锚点P11、P12对应的第二补偿增益，基于线性插值的方式确定位于第一锚点P11、P12之间位置处的像素对应的补偿增益。这仅仅是一个示例，并不用于限定本申请。
示例性的，像素可以包括不同颜色的子像素，因此第二补偿增益可以包括不同颜色的子像素各自对应的第二补偿增益。另外，不同灰阶下，第 二补偿增益的具体数值可以不同。
本申请实施例还提供一种亮度补偿装置。如图13所示，本申请实施例提供的亮度补偿装置300可包括锚点设置模块301、第一补偿增益确定模块302、第二补偿增益确定模块303及补偿模块304。
