搭载中小尺寸显示面板的电子产品，使用周期在2～3年左右，电子产品对于显示面板寿命的要求，通过优化器件的结构，使用较高寿命的发光材料，以及搭配DBI(DeBurnIn)算法，实现显示面板老化补偿，对于小尺寸的显示面板的使用寿命通常可以达标。
在显示面板使用环境比较严苛的情况下，例如在夏季车载屏长期暴露于较高温度中，显示面板常常处于较强的环境光下工作，显示画面较手机也更为单一，多为一些固定图标或导航画面；在笔记本电脑上的显示面板，通常也会在较高环境光下使用，使用过程中有固定图标(如桌面左下角windows图标等)，且车载屏及笔记本的使用年限明显长于中小尺寸电子产品，因此对于大尺寸显示面板的寿命有着极为严苛的要求，即使在优化器件结构，使用较高寿命的发光材料，以及搭配DBI(DeBurnIn)算法后，显示面板仍然存在老化严重的问题，显示面板的使用寿命仍然难以达标。
本公开实施例提供一种补偿装置，如图1所示，可以包括第一存储器11、第一计时器12和处理器13；
第一存储器11，与处理器13连接，可以设置为存储第一时间节点值、 第二时间节点值、前期补偿参数集、中期补偿参数集、后期补偿参数集；第一时间节点值小于第二时间节点值，前期补偿参数集、中期补偿参数和后期补偿参数集中均包括至少一种补偿参数，且同一种补偿参数在前期补偿参数集和中期补偿参数集中的值不同于在后期补偿参数集中的值，前期补偿参数集中的补偿参数值随时间逐渐降低、后期补偿参数集中的补偿参数值随时间逐渐提高；
第一计时器12，与处理器13连接，可以设置为自处理器13接收到像素数据开始计时得到第一计时信息，并将第一计时信息发送至处理器13；所述像素数据包括：灰阶数据；
处理器13，分别与第一计时器12和第一存储器11连接，可以设置为接收像素数据和第一计时信息，在第一计时信息未达到第一时间节点值的状态下，根据第一计时信息和前期补偿参数集中的补偿参数对像素数据的灰阶数据进行补偿；在第一计时信息达到第二时间节点值且未达到第二时间节点值的状态下，根据第一计时信息和中期补偿参数集中的补偿参数对像素数据的灰阶数据进行补偿；在第一计时信息达到第二时间节点值的状态下，根据第一计时信息和后期补偿参数集中的补偿参数对像素数据的灰阶数据进行补偿。
本公开实施例提供的补偿装置，第一计时器设置为自处理器接收到像素数据开始计时得到第一计时信息，并将第一计时信息发送至处理器，处理器设置为接收像素数据和第一计时信息，在第一计时信息未达到第一时间节点值的状态下，根据第一计时信息和前期补偿参数集中的补偿参数对像素数据的灰阶数据进行补偿，在第一计时信息达到第一时间节点值且未达到第二时间节点值的状态下，根据第一计时信息和中期补偿参数集中的补偿参数对像素数据的灰阶数据进行补偿；在第一计时信息达到第二时间节点值的状态下，根据第一计时信息和后期补偿参数集中的补偿参数对像素数据的灰阶数据进行补偿。将本公开实施例提供的补偿结构应用于显示面板，在很大程度上减缓显示面板的老化，提高了显示面板的使用寿命。
在示例性实施方式中，同一种补偿参数在前期补偿参数集和后期补偿参数集中的值不同于在中期补偿参数集中的值，可以包括：同一种补偿参数在前期补偿参数集和后期补偿参数集中的值大于在中期补偿参数集中的值。
在本公开实施例中，可以根据第一时间节点和第二时间节点，将显示面板的使用时间划分为前期、中期和后期，在这三个期间分别通过前期补偿参数集、中期补偿参数集、后期补偿参数集对像素数据进行补偿，前期补偿参数集中的补偿参数值逐渐降低、后期补偿参数集中的补偿参数值逐渐提高，将显示面板前期的灰阶适当降低，在显示面板前期适当降低灰阶，在显示面板后期的灰阶适当提高灰阶，可以使得显示面板的前期、中期和后期三个节点的显示效果相差较小、减缓显示面板的老化速度。
在示例性实施方式中，第一存储器11，还可以设置为存储第三时间节点值、最大补偿参数集，第三时间节点值大于第二时间节点值，最大补偿参数集中包括至少一种补偿参数，且同一种补偿参数在最大补偿参数集中的值大于在后期补偿参数集中的值；
处理器13，还可以设置为在第一计时信息达到第三时间节点值的状态下，根据第一计时信息和最大补偿参数集中的补偿参数对像素数据的灰阶数据进行补偿。
在本公开实施例中，第三时间节点值以后，显示面板使用最大补偿参数集进行补偿，且补偿参数在最大补偿参数集中的值大于在后期补偿参数集中的值，使得显示面板在最后使用阶段使用最大补偿值对灰阶进行补偿，提高显示面板在最后工作阶段的显示效果。
在示例性实施方式中，第一存储器11可以设置为：存储多个时间点对应的补偿参数，前期补偿参数集包括第一时间节点值之前的多个时间点对应的补偿参数；中期补偿参数集包括第一时间节点值和第二时间节点值之间的多个时间点对应的补偿参数；后期补偿参数集包括第二时间节点值和第三时间节点值之间的多个时间点对应的补偿参数；最大补偿参数集包括第三时间节点值之后的多个时间点对应的补偿参数；
处理器13可以设置为：根据第一计时信息查找对应的时间点，根据查找的时间点确定补偿参数集，根据确定的补偿参数集中与查找的时间点对应的补偿参数对接收的像素数据的灰阶数据进行补偿，得到补偿后的灰阶数据。
在示例性实施方式中，前期补偿参数集中，同种补偿参数的多个补偿参数值按照对应时间点的顺序逐渐减小；
中期补偿参数集中，同种补偿参数的参数值相同；
后期补偿参数集中，同种补偿参数的多个参数值按照对应时间点的顺序逐渐增大；
最大补偿参数集中，同种补偿参数的参数值相同。
在本公开实施中，第一时间节点、第二时间节点和第三时间节点可以根据显示面板的使用周期以及显示面板的老化特点进行设定，比如在显示面板灰阶显示降低速度比较快的前期，对灰阶进行补偿的补偿参数逐渐的缓慢降低，在显示面板使用的中期，老化速度减缓，可以采用基本恒定的补偿参数对灰阶进行补偿，在显示面板的后期，显示面板进一步老化，可以采用对灰阶的补偿参数值逐渐提高的方式，当达到最大补偿参数值时，采用恒定的最大补偿参数进行补偿。例如，第一时间节点为显示面板工作500个小时左右，第二时间节点为显示面板工作1500个小时作用，第三个时间节点可以为显示面板工作3000个小时左右。
在本公开实施例中，补偿参数的值可以为小于或等于1的数值，例如，前期补偿参数集中，同种补偿参数的多个补偿参数值按照对应时间点的顺序由1逐渐减小至0.5；中期补偿参数集中同种补偿参数的参数值相同，例如可以为0.5；后期补偿参数集中同种补偿参数的多个参数值按照对应时间点的顺序由0.5逐渐增大到1；最大补偿参数集中，同种补偿参数的参数值相同，例如补偿参数均为1。
在示例性实施方式中，多个时间点对应的补偿参数可以包括多个时间点对应的亮度权重和灰阶权重；
处理器13可以设置为：根据第一计时信息确定对应的时间点，根据确定的时间点确定对应的亮度权重和灰阶权重，将获取的亮度权重与确定的灰阶权重相乘得到补偿的灰阶权重，根据像素数据中的灰阶数据与补偿的灰阶权重得到补偿后的灰阶数据。
在示例性实施方式中，处理器13可以设置为，将像素数据中的灰阶数据与补偿的灰阶权重相乘得到补偿后的灰阶数据。
例如，第一计时信息确定对应的时间点在第一时间节点之前，处理器13 根据确定的时间点确定对应的亮度权重为0.8、灰阶权重为0.6，将获取的亮度权重0.8与确定的灰阶权重0.6相乘得到补偿的灰阶权重0.48，根据像素数据中的灰阶数据与补偿的灰阶权重0.48相乘得到补偿后的灰阶数据。
在本公开实施例中，处理器13可以获取像素数据的亮度数据(亮度数据可以为数字亮度值，英文全称为Digital Brightness Value，简写为DBV)，每个时间点对应的DBV对应设置好亮度权重，并对每个时间点设置好灰阶权重，第一计时器达到对应的时间点，在该时间点对应的亮度权重和灰阶权重相乘得到补偿的灰阶权重，使用补偿的灰阶权重与像素中的灰阶数据相乘得到补偿后的灰阶数据。
本公开实施例中采用对显示面板整体进行灰阶补偿，减缓老化的趋势基本一致，不易出现显示面板局部过补偿的问题。
在示例性实施方式中，补偿装置还可以包括计时存储器；
计时存储器，与处理器13和第一计时器12连接，设置为存储第一计时器12的第一计时信息；
第一计时器12，还与计时存储器连接，设置为在处理器13断电后重新启动的情况下，读取计时存储器中的第一计时信息，在处理器13重启后并重新开始接收像素数据的情况下，在第一存储器11中存储的第一计时信息的基础上继续计时。
在本公开实施例中，可以通过计时存储器，可以保存第一计时器12的第一计时信息，在显示面板停止工作后，隔一段时间再次工作时，可以在显示面板停止工作的第一计时信息的基础上继续计时，避免将不工作的时间段累加在第一计时信息中，从而提高显示面板灰阶补偿的准确性。
在示例性实施方式中，补偿装置还可以包括第二计时器、第二存储器、温度传感器；
第二存储器，与处理器13连接，可以设置为存储温度阈值、多个时间点对应的测试补偿参数、高灰阶阈值和低灰阶阈值；
温度传感器，与处理器13连接，可以设置为获取温度信息，并将温度信息传输至处理器13；
第二计时器，与处理器13连接，可以设置为在处理器13的控制下计时，得到第二计时信息，并将第二计时信息发送给处理器13；
处理器13，分别与第二计时器、第二存储器、温度传感器连接，还可以设置为获取测试像素数据和温度信息，根据测试像素数据中的灰阶数据得到测试像素数据的灰阶分布信息，在灰阶分布信息的高灰阶占比超出高灰阶阈值、或者灰阶分布信息中低灰阶占比超出低灰阶阈值、或者获取的温度信息超出温度阈值的情况下，控制第二计时器开始计时，根据第二计时信息和多个时间点对应的测试补偿参数对测试像素数据中的灰阶数据进行补偿。
如图3所示，处理器13获取的测试像素数据的灰阶分布信息中，低灰阶(灰阶值小于Low Gray)和高灰阶(灰阶值大于High Gray)分布较为集中，低灰阶占比超出低灰阶阈值可以理解为低灰阶数据与灰阶数据总数比值大于低灰阶阈值，即小于Low Gray的值的占比超过低灰阶阈值；高灰阶占比超出高灰阶阈值可以理解为高灰阶数据与灰阶数据总是比值大于高灰阶阈值，即大于High Gray的值的占比超过高灰阶阈值。例如，可以设置高灰阶阈值为0.3，设置低灰阶阈值为0.3。
在本公开实施例中，温度信息可以通过温度传感器获取，温度阈值可以根据实际情况设置。
在本公开实施例中，在显示面板测试阶段，多参数可调(如高灰阶阈值、低灰阶阈值、温度阈值)，可以灵活配置灰阶阈值、低灰阶阈值、温度阈值等参数，对不同显示面板的老化测试设置不同的阈值，提高了显示面板在老化测试过程的灵活性。比如，可以设置高灰阶阈值、低灰阶阈值、温度阈值其中一个或多个超标，控制第二计时器开始计时，根据第二计时信息和多个时间点对应的测试补偿参数对测试像素数据中的灰阶数据进行补偿。
在示例性实施方式中，测试补偿参数可以包括亮度权重和测试灰阶权重；
处理器13，可以设置为根据第二计时信息确定对应的时间点，根据确定的时间点确定对应的测试亮度权重和测试灰阶权重，将测试亮度权重与测试灰阶权重相乘得到测试的补偿灰阶权重，根据测试的补偿灰阶权重与测试像素数据中的灰阶数据相乘得到补偿后的测试灰阶数据。
在本公开实施例中，处理器13可以获取测试像素数据的测试亮度数据 (亮度数据可以为数字亮度值，英文全称为Digital Brightness Value，简写为DBV)，每个时间点对应的DBV对应设置好测试亮度权重，并对每个时间点设置好测试灰阶权重，第二计时器达到对应的时间点，在该时间点对应的测试亮度权重和测试灰阶权重相乘得到测试的补偿灰阶权重，使用补偿的灰阶权重对像素中的灰阶数据相乘得到补偿后的灰阶数据。
在本公开实施例中，在显示面板老化测试过程中，可有效降低老化速度，老化500h，保守估计可提升寿命约20％，
在示例性实施方式中，第二存储器，可以设置为存储第一测试时间节点值、第二测试时间节点值、第三时间测试时间节点值；
第一测试时间节点的值小于第二测试时间节点的值，第二测试时间节点的值小于第三测试时间节点的值、前期测试补偿数据、中期测试补偿数据、后期测试补偿数据、最大测试补偿数据；所述第一测试时间节点的值小于所述第二测试时间节点的值，所述第二测试时间节点的值小于所述第三测试时间节点的值；
前期测试补偿数据包括第一测试时间节点之前的多个时间点对应的测试亮度权重和测试灰阶权重，中期测试补偿数据包括第一测试时间节点与第二测试时间节点之间的多个时间点对应的测试亮度权重和测试灰阶权重，后期测试补偿数据包括第二测试时间节点与第三节点之间的多个时间点对应的测试亮度权重和测试灰阶权重，最大测试补偿数据包括第三测试时间节点之后的多个时间点对应的测试亮度权重和测试灰阶权重；在前期测试补偿数据中，多个测试亮度权重和多个测试灰阶权重的值按照对应时间点的顺序逐渐减小；
在中期测试补偿数据和最大测试补偿数据中，多个测试亮度权重和多个测试灰阶权重的值保持不变；
在后期测试补偿数据中，多个测试亮度权重和多个测试灰阶权重的值按照对应时间点的顺序逐渐增大；
中期测试补偿数据中多个时间点对应的测试亮度权重和测试灰阶权重小于前期测试补偿数据和后期测试补偿数据中多个时间点对应的测试亮度权重和测试灰阶权重的值；最大测试补偿数据中多个时间点对应的测试亮度权重和测试灰阶权重大于前期测试补偿数据和后期测试补偿数据中多个时间点对 应的测试亮度权重和测试灰阶权重的值。
本公开实施例中补偿装置中包括第二计时器、第二存储器、温度传感器，可以应用于对显示面板老化测试，如图2所示，可以为显示面板在测试过程中或者在显示面板实际使用过程中不同阶段(stage1至stage5)的像素数据灰阶值输出，横坐标为时间，纵坐标为灰阶值输出。图2中根据①～④四个点的位置对stage1至stage5进行划分，其中，stage2至stage5在显示面板老化测试过程中可以分别对应上述实施例中所述的前期测试补偿数据、中期测试补偿数、后期测试补偿数据、最大测试补偿数据对应的时间阶段；在显示面板使用过程中，图2中的stage1阶段可以省去，图2的stage2至stage5在显示面板使用过程中可以分别对应上述实施例中所述的前期补偿参数集、中期补偿参数集、后期补偿参数集、最大补偿参数集对应的时间阶段。本公开实施例中，可以通过补偿装置对OLED显示面板的灰阶数据进行补偿，并利用OLED显示面板本身缺陷(点亮初期，屏幕亮度衰减较快，而持续老化一段时间后，老化速度区域平稳)，在满足显示要求的前提下，在前期适当通过降低灰阶达到降低亮度的目的，在中期保持灰阶，在后期缓慢提升灰阶的方式，达到减缓OLED显示面板老化的目的，并使得OLED显示面板在整个生命周期显示的灰阶相对一致。
图4所示为未使用补偿装置对灰阶进行补偿的情况下，显示面板在不同阶段灰阶显示的示意图，图5所示为使用本公开实施例的补偿装置对灰阶进行补偿的情况下，显示面板在不同阶段灰阶显示的示意图，图4和图5中的百分比为当前阶段的灰阶显示与未衰减的灰阶显示的百分比，从图4和图5可以看随着显示面板使用时间的延长，显示的灰阶逐渐降低，也就是显示面板逐渐老化的过程，使用本公开实施例提供的补偿装置对显示面板的灰阶进行补偿之后，显示面板老化速度会变慢，在一定程度上缓解了显示面板的老化。
在本公开实施例中，处理器13可以从主机获取像素数据。例如在测试显示面板老化的过程中，处理器13可以接收来自主机图片的像素数据。
在示例性实施方式中，处理器13的逻辑结构如图6所示，可以分为灰阶分布检测模块(Pattem Detection)、静态图像检测模块(Static Image Detection)、 温度约束模块(Temperature Constraint)、灰阶逻辑模块(Counter Logic)、亮度权重逻辑模块(Weight Logic)五个功能模块(此五个功能模块可以通过一个或多个算法实现)，下面结合图6以测试显示面板老化过程为例对处理器13的工作过程进行说明，处理器13接收到像素数据(i_data)之后，处理器中各功能模块执行以下操作：
灰阶分布检测功能模块(Pattem Detection)：根据像素数据的灰阶分布直方图判断灰阶分布是否达到高灰阶阈值或低灰阶阈值(即判断高灰阶和低灰阶是否集中)，例如可以通过对TCON/DIC发送的图片灰阶(像素数据中灰度数据)分布进行分析，在图3所示的灰阶分布图中，低灰阶(灰阶值小于Low Gray)和高灰阶(灰阶值大于High Gray)分布较为集中；在棋盘的像素数据的灰阶分布方式中，小于10灰阶占40％，大于250Gray占40％,则很容易筛选出棋盘格图片。而一般图片则灰阶分布较广或最高灰阶、最低灰阶占比不大。在本公开实施例中，灰阶分布检测功能模块(Pattem Detection)可以根据预设的高灰阶阈值和低灰阶阈值判断是否满足灰阶补偿的条件。
静态图像检测模块(Static Image Detection)：收到每一帧的帧同步信号(v-sync)后，通过循环冗余校验(英文全称为：Cyclic Redundancy Check，简写为CRC)，判断输入图片数据(像素数据)是否与上一张图片(即上一帧的像素数据)相同，如当前帧与上一帧画面的CRC校验值相同，则判定为同一张图片，即静止图片，此时可以对静止图片进行计数(例如可以通过计数器进行计数)或者可以对检测静止图片进行计时。当计数值或计时值大于某一设定的阈值的情况下，判定为Static Image state(静止状态)，达到补偿灰阶的条件，其中高灰阶阈值和低灰阶阈值可以根据实际情况进行设置。
温度约束模块(Temperature Constraint)：获取温度传感器反馈的温度(i_temp)，判断是否达到温度阈值，达到温度阈值则满足灰阶补偿的条件。其中温度阈值可以根据实际情况设置。
灰阶逻辑模块(Counter Logic)：根据计数值找到对应的灰阶权重。例如，不同的计数值对应的灰阶权重可以如表1所示。

在本公开实施例中，可以结合分布检测模块(Pattem Detection)、静态图像检测模块(Static Image Detection)、温度约束模块(Temperature Constraint)得到的结果，决定是否使能(即是否进行灰阶补偿)，并根据静止图片的计数值及配置参数，绑点与绑点之前采用线性插值。配置参数可以为计数值的阈值、高灰阶阈值、低灰阶阈值、温度阈值，可以通过调整计数值的阈值、 高灰阶阈值、低灰阶阈值、温度阈值调整图2中调整①～④四个点的位置，以及设置灰阶逻辑模块(Counter Logic)中表1不同计数值的灰阶权重和亮度权重逻辑模块(Weight Logic)中表2不同亮度值的亮度权重，实现如图2中的stage1～stage5的阶段。
