具体实施方式
为了能够更加详尽地了解本公开实施例的特点与技术内容，下面结合附图对本公开实施例的实现进行详细阐述，所附附图仅供参考说明之用，并非用来限定本公开实施例。在以下的技术描述中，为方便解释起见，通过多个细节以提供对所披露实施例的充分理解。然而，在没有这些细节的情况下，至少一个实施例仍然可以实施。在其它情况下，为简化附图，熟知的结构和装置可以简化展示。
如图1所示，本公开实施例提供的发光器件的光学补偿方法，包括：
S101、获得发光器件的多个发光单元的光学数据，基于光学数据将多个发光单元划分为补偿组和非补偿组；
S102、根据非补偿组中的发光单元的光学数据，确定补偿组中的发光单元的补偿系数；
S103、根据补偿系数对补偿组中的发光单元进行光学补偿。
在一些实施例中，如图2所示，发光器件20上包括多个发光单元201。可选地，该发 光器件可以是LED(Light Emitting Diode，发光二极管)、微Micro LED(LED微缩化和矩阵化技术)及迷你Mini LED(芯片尺寸介于50～200μm之间的LED)中的任意一个。该发光单元可以是该发光器件上的最小发光单位。
在一些实施例中，上述多个发光单元可以是发光器件中的全部的发光单元，也可以是部分的发光单元。可以通过一些现有的检测手段获取发光器件上的多个发光单元的光学数据。
可选地，获取发光单元的光学数据可以是在指定时间获取的，也可以是周期性获取的。由于发光器件中的发光单元可以是新的发光单元，也可以是回收的已使用过的发光单元，回收的发光单元的已使用时长可能相同也可能不同，例如有的发光单元已使用了几年，有的发光单元已使用了几个月，从而导致发光器件中的这些发光单元的发光的衰减速度随时间的变化程度是不同的。因此可以按照时间周期(例如6个月、1年，等)对发光器件的发光单元进行检测，获取发光单元的光学数据，以便对发光器件进行动态光学补偿。举例来讲，以1年为一个时间周期，在第一时间周期内，检测发光单元的光学数据为100，若该发光单元被划分为补偿组，则针对当前光学数据(100)得到补偿系数r1，从而基于r1对该发光单元进行光学补偿；在第二时间周期内，检测该发光单元的光学数据为90，若该发光单元被划分为补偿组，则针对当前光学数据(90)得到补偿系数r2，从而基于r2对该发光单元进行光学补偿。因此在不同时间，同一发光单元的光学数据可能不同，补偿系数也可能不同，通过周期性检测可以实现对发光单元的动态补偿。
可选地，该光学数据可以是一次获取的多个发光单元对应的一组光学数据，或者是多次获取的多个发光单元对应的多组光学数据的平均值。
在一些实施例中，如图3A、图3B、图3C所示，可以将发光器件20上的多个发光单元201划分成补偿组(图中灰色背景区域)和非补偿组(图中白色背景区域)。可选地，补偿组和非补偿组的划分形式可以是连续的区域或者不连续的区域，补偿组和非补偿组的区域形状和大小没有限定。可选地，图3A至图3C中的补偿组和非补偿组的名称还可以互换。
本公开通过对补偿组的发光单元进行光学补偿，可以提高发光器件的光学均匀性。
在一些实施例中，在基于光学数据将上述多个发光单元划分为补偿组和非补偿组时，该补偿组中的发光单元数量小于该非补偿组中的发光单元数量。
本公开通过设置补偿组的发光单元数量小于非补偿组的发光单元的数量，可以实现在对补偿组的发光单元进行光学补偿时，补偿该发光器件上相对少量的发光单元，从而可以提高光学均匀性，同时减少补偿工作量。
在一些实施例中，在基于光学数据将多个发光单元划分为补偿组和非补偿组之前，还可以根据光学数据将上述多个发光单元分为多个子组，每个子组至少包括一个发光单元；然后计算每个子组中的发光单元数量在上述多个发光单元中的占比；基于该占比将上述多个子组划分为补偿组和非补偿组，其中，该补偿组中的占比总数小于该非补偿组中的占比总数。
在一些实施例中，如图4A、图4B、图4C、图4D所示，可以根据光学数据将发光器件40上的多个发光单元划分成多个子组41，每个子组包括至少一个发光单元。可选地，子组可以是规则的区域，也可以是不规则的区域，如图4A所示，子组41中包括子组A、子组B、子组C及子组D，每个子组可以是规则的区域；如图4B所示，子组41中包括子组A、子组B、子组C及子组D，每个子组可以是不规则的区域。可选地，子组可以是连续的区域或不连续的区域。如图4C所示，子组41中包括子组A、子组B、子组C及子组D，其中子组C是不规则且不连续的区域，其他子组也可以是不连续的区域。如可选地，子组中可以包括一个发光单元，或者多个发光单元，还可以如图4D所示，每个发光单元可以是一个子组41。由于子组是基于光学数据划分，因此子组的区域大小和形状不受发光单元的位置限制。
在一些实施例中，计算每个子组中的发光单元数量在上述多个发光单元中的占比，可以统计每个子组的发光单元数量a，然后将计算数量a与上述多个发光单元的数量b的比值，计算公式可以是：(a/b)*100％＝占比。
例如，子组的发光单元数量a＝1000，上述多个发光单元的数量b＝10000，则该子组的占比为：
占比＝(a/b)*100％＝(1000/10000)*100％＝10％。
在一些实施例中，在基于占比将多个子组划分为补偿组和非补偿组时，该非补偿组中包括上述多个子组中占比最大的子组。
如图5所示，先将发光器件40上的多个发光单元划分成多个子组41，子组41中包括子组A、子组B、子组C及子组D，分别计算每个子组的发光单元数量在上述多个发光单元中的占比，得到子组A的占比a、子组B的占比b、子组C的占比c及子组D的占比d，其中各个占比从大到小的排序为：a>d>b>c。再将这四个子组划分成补偿组和非补偿组。如图所示，子组A和子组D为非补偿组(图中灰色背景区域)，子组B和子组C为补偿组(图中白色背景区域)，非补偿组的发光单元的总占比大于补偿组的发光单元总占比，其中，非补偿组中包括占比最大的a所对应的子组A。在可选的实施例中，分组方式还可以包括其他方案，例如，子组A和子组B为非补偿组，子组C和子组D为补偿组；或者，子组 A和子组C为非补偿组，子组B和子组D为补偿组；又或者，子组A、子组B和子组C为非补偿组，子组D为补偿组，等。分组方案只要满足非补偿组的发光单元总数大于补偿组的发光单元总数并且非补偿组包括占比最大的子组即可，分组方案不做限定。
本公开通过将占比最大的子组划分到非补偿组，可以使非补偿组中的发光单元的一致性相对增高，使均匀性补偿效果更佳优化。
在一些实施例中，根据光学数据将多个发光单元分为多个子组的方法可以是将光学数据差值在第一范围内的发光单元分为一个子组，从而得到上述多个子组。例如，可以选择发光器件上的光学数据最小的发光单元A为起点，选择光学数据大于该发光单元A且偏差在第一范围内的全部发光单元，将这些发光单元作为第一子组；然后在第一子组外，选择光学数据最小的发光单元B为新的起点，继续选择光学数据大于该发光单元B且偏差在第一范围内的全部发光单元，将这些发光单元作为第二子组；以此类推，直至将上述多个发光单元全部划分完成。还可以采用其他分组方式，此处不做限定。
在一些实施例中，子组的分组方式可以如图6A、图6B、图6C所示。其中，如图6A所示，发光器件40包括多个发光单元，每个小格代表一个发光单元，小格里的数据可以为该发光单元对应的光学数据。基于上述子组划分方法，可以将最小光学数据90对应的发光单元为起点，假设第一范围为9，那么光学数据从90到99的发光单元可以分为一个子组，记为子组A；第二个起点是光学数据为100的发光单元，第一范围为9，那么光学数据从100到109的发光单元可以分为一个子组，记为子组B；第三个起点是光学数据为110的发光单元，第一范围为9，那么光学数据从110到119的发光单元可以分为一个子组，记为子组C；第四个起点是光学数据为120的发光单元，第一范围为9，那么光学数据从120到129的发光单元可以分为一个子组，记为子组D；子组的分组结果如图6B所示，其中背景图案相同的发光单元为一个子组，子组A和子组B在发光器件中的区域不连续，子组C和子组D在发光器件中的区域连续。
在一些实施例中，子组划分完成后，可以划分补偿组和非补偿组，划分结果如图6C所示，其中，可以将子组B和子组C作为非补偿组(图中灰色背景区域)，子组A和子组D作为补偿组(图中白色背景区域)，其中，子组B可以是发光单元占比最多的子组。
在一些实施例中，在确定补偿组中的发光单元的补偿系数时，可以确定该补偿组中的每个子组的补偿系数。可选地，同一子组中的发光单元的补偿系数相同或不同。如图6C所示，确定补偿组中的子组A和子组D的补偿系数，其中子组A可以对应补偿系数r1和子组D可以对应补偿系数r2，则子组A中的每个发光单元的补偿系数可以是r1，子组D中的每个发光单元的补偿系数可以是r2。
在一些实施例中，在确定该补偿组中的每个子组的补偿系数时，可以针对上述每个子组中的任一子组，将该任一子组分成多个发光单元块；然后确定该任一子组中的每个发光单元块的补偿系数。可选地，同一发光单元块中的发光单元的补偿系数可以相同或不同。可选地，发光单元块可以包括该子组中的至少一个发光单元。
在一些实施例中，可以将子组中的发光单元按照在发光器件中的位置划分，例如，根据发光单元的位置信息，将子组中的位置信息满足一定条件的发光单元分为一个发光单元块，以使可以通过记录该发光单元块的少量位置信息来确定该发光单元块中全部发光单元的位置。
在一些实施例中，可以将子组中同一列或同一行的连续的发光单元分为一个发光单元块，以该行或列的首位两个端点的发光单元的位置信息作为该发光单元块的位置信息，从而可以通过两个位置信息就确定该发光单元块中全部发光单元的位置；或者，可以将子组中位于一个矩形中的发光单元划分为一个发光单元块，以该矩形的四个角的发光单元的位置信息作为发光单元块的位置信息，从而可以通过四个位置信息就确定该发光单元块中全部发光单元的位置；又或者，可以将子组中位于一个圆形中的发光单元划分为一个发光单元块，以该圆形的圆心和半径作为发光单元块的位置信息，从而可以通过两个位置信息就确定该发光单元块中全部发光单元的位置。
如图7A所示，发光器件70包括多个发光单元，每个小格代表一个发光单元，小格里的数据可以为该发光单元对应的光学数据。基于上述子组划分方法，可以将发光器件70划分为多个子组。以发光器件70中的第一子组(图中灰色背景区域)为例，将第一子组按照位置信息划分为多个发光单元块。如图7B所示，以上述矩形划分方式为例，可以将该第一子组划分为两个发光单元块，即发光单元块A(图中斜线背景区域)和发光单元块B(图中网格背景区域)。可以将发光单元块四个角的发光单元的位置信息作为发光单元块的位置信息，从而可以记录发光单元块的位置信息及补偿系数即可得到发光单元块中的全部发光单元的位置信息和补偿系数。例如图7B中，可以记录发光单元块A的四个角对应的4个位置信息及补偿系数，从而得到发光单元块A中的12个发光单元的位置信息，因此可以减少位置信息的存储数量。
这样在记录发光单元的补偿系数时，可以只记录发光单元块的位置信息，以及发光单元块对应的补偿系数，可以避免记录发光单元块中的每个发光单元的位置信息及补偿系数，从而节省存储空间。
在一些实施例中，在将上述任一子组分成多个发光单元块时，可以将该任一子组中的光学数据差值在第二范围内的发光单元分为一个发光单元块，从而得到多个发光单元块。 例如，可以选择子组中的光学数据最小的发光单元A为起点，选择光学数据大于该发光单元A且偏差在第二范围内的全部发光单元，将这些发光单元作为发光单元块A；然后在发光单元块A外，选择光学数据最小的发光单元B为新的起点，继续选择光学数据大于该发光单元B且偏差在第二范围内的全部发光单元，将这些发光单元作为发光单元块B；以此类推，直至将该子组中的发光单元全部划分完成。
可选地，如果子组是按照上述实施例中的第一范围进行划分，则该第二范围可以小于该第一范围。
如图7A所示，假设，第一范围为9，依据上述划分子组的方法将发光器件70划分为多个子组，以光器件70中的第一子组(图中灰色背景区域)为例，将第一子组按照光学数据划分为多个发光单元块。基于上述子组划分方法，可以将最小光学数据100对应的发光单元为起点，假设第二范围为4(小于第一范围)，那么光学数据从100到104的发光单元可以分为一个发光单元块，记为发光单元块A；第二个起点是光学数据为105的发光单元，第二范围为4，那么光学数据从105到109的发光单元可以分为一个发光单元块，记为发光单元块B，从而得到如图7C所示的分组结果。
在一些实施例中，在确定上述任一子组中的每个发光单元块的补偿系数时，可以将该任一子组中的任一发光单元块中的全部发光单元的光学数据的平均值作为该发光单元块的光学数据；然后基于该发光单元块的光学数据确定该发光单元块的补偿系数。可选地，光学数据不同的发光单元块的补偿系数可以相同或不同。
上述基于发光单元的光学数据划分发光单元块的方式可以使同一发光单元块中的发光单元的光学数据相差较小，因此针对同一发光单元块设置一个补偿系数可以使得同一发光单元块的补偿效果更佳均匀。
在一些实施例中，在确定补偿组中的发光单元的补偿系数时，可以根据非补偿组中的光学数据确定至少一个基准数据；然后基于该基准数据确定该补偿组中的发光单元的补偿系数。
在一些实施例中，如图8A所示，该图中所示可以是光学数据的分布曲线，其中，横坐标为光学数据的数值，纵坐标为光学数据的占比，也就是光学数据相同或相近(如差值在预设范围内)的发光单元数量在发光单元总数中的占比。从图中可以看到基于光学数据的补偿组和非补偿组的划分结果。由于非补偿组是连续的，因此可以从非补偿组中确定一个基准数据(例如占比最大的光学数据)，从而基于该基准数据确定补偿组的发光单元的补偿系数。如图8B所示，该图中所示可以是光学数据的分布曲线，其中，横坐标为光学数据的数值，纵坐标为光学数据的占比，也就是光学数据相同或相近(如差值在预设范围内) 的发光单元数量在发光单元总数中的占比。从图中可以看到基于光学数据的补偿组和非补偿组的划分结果。由于非补偿组是不连续的，因此可以从非补偿组的两部分中，基于每个部分确定一个基准数据(例如每个部分中占比最大的光学数据)，从而基于这两个基准数据确定补偿组的发光单元的补偿系数。
在一些实施例中，同一个补偿组可以对应至少一个的基准数据，例如补偿组中的每个子组对应一个基准数据。可选地，同一子组中的每个发光单元块也可以对应一个基准数据。
在一些实施例中，基准数据可以包括以下数据中的至少之一：非补偿组中的光学数据的最大值、非补偿组中的光学数据的最小值、非补偿组中的光学数据的平均值。
在一些实施例中，上述光学数据，可以包括：亮度数据和色度数据至少之一。
在一些实施例中，在根据非补偿组中的发光单元的光学数据确定补偿组中的发光单元的补偿系数时，可以在光学数据为亮度数据时，确定该补偿系数为亮度补偿系数；或，在光学数据为色度数据时，确定该补偿系数为色度补偿系数；或，在光学数据为亮度数据和色度数据时，该补偿系数可以是由亮度补偿系数和色度补偿系数结合的综合补偿系数。
在一些实施例中，当光学数据为亮度数据时，还可以确定亮度数据低于亮度阈值的发光单元为坏点；然后在根据补偿系数对补偿组中的发光单元进行光学补偿时，可以根据补偿系数对该补偿组中的除坏点以外的发光单元进行光学补偿。
在一些实施例中，如图9所示，该图中所示可以是亮度的分布曲线，其中，横坐标为亮度值，纵坐标为亮度值的占比，也就是亮度值相同或相近(如差值在预设范围内)的发光单元的数量在全部发光单元总数中的占比。假设亮度阈值为10，则亮度值低于10的发光单元则为坏点。
在一些实施例中，在根据非补偿组中的发光单元的光学数据确定补偿组中的发光单元的补偿系数之后，还可以将补偿区中的发光单元的位置信息及补偿系数存储至预设存储空间；在根据补偿系数对补偿组中的发光单元进行光学补偿时，可以从该预设存储空间中获取补偿组中的发光单元的补偿系数，根据该补偿系数对发光单元进行光学补偿。
在一些实施例中，根据补偿系数对补偿组中的发光单元进行光学补偿，可以在控制该补偿组中的发光单元点亮时，根据发光单元对应的补偿系数，调整发光单元的供电电压和供电电流中的至少一种，从而实现发光单元的光学补偿。
在一些实施例中，光学补偿可以包括正补偿和负补偿。例如，基准数据为100时，小于100的光学数据对应的发光单元需进行正补偿，即增大光学数据的数值；大于100的光学数据对应的发光单元需进行负补偿，即减小光学数据的数值。
