具体实施方式
下面将结合本公开实施例中的附图，对本公开实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅仅是本公开一部分实施例，而不是全部的实施例。基于本公开中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都属于本公开保护的范围。
考虑到驱动晶体管老化会影响显示装置的显示效果，因此采取对驱动晶体管的老化程度进行检测并补偿的方式来确保显示产品的正常显示，相关技术是在两帧图像之间对一行子像素中一种颜色子像素的驱动晶体管的老化程度进行检测。如图1所示，相关技术是按照某一颜色顺序例如红、绿、蓝、白依次对各颜色子像素中驱动晶体管的老化程度进行检测并补偿，且一直按照该颜色顺序循环检测并补偿。
然而，以显示产品有2160行为例，对一种颜色的所有子像素的驱动晶体管检测完就需要2160帧，在显示产品包括四种颜色的子像素的情况下，对一种颜色检测完后需要再过2160×3帧才能对该颜色子像素中的驱动晶体管再次进行检测。由于某个颜色使用频率高时，该颜色子像素中的驱动晶体管会较快的老化，而其它颜色使用频率低的子像素中的驱动晶体管老化的并不明显，这样便导致不能对老化的驱动晶体管及时检测并补偿。
基于此，本公开的一些实施例提供一种数据处理顺序的确定方法，用于确定显示多种颜色的显示装置中的选中颜色，以对该选中颜色进行数据处理。显示装置包括多个像素，每个像素包括用于显示多种颜色的多个子像素。对于每个像素中多个子像素的颜色不进行限定。例如，每个像素包括红色子像素、绿色子像素、蓝色子像素。又例如，每个像素包括红色子像素、绿色子像素、蓝色子像素以及白色子像素。
在一些实施例中，显示装置仅包括显示面板。在另一些实施例中，显示装置除包括显示面板外，还包括其它部件，如驱动IC(Integrated Circuit，集成电路)等。在一些实施例中，显示装置为液晶显示装置(Liquid Crystal Display，简称LCD)。在另一些实施例中，显示装置 为自发光显示装置，由于自发光显示装置自身就能够发光，不需要借助背光模组提供显示所需的光，因而相对于液晶显示装置，自发光显示装置结构更简单。在一些实施例中，自发光显示装置为有机电致发光显示装置(Organic Light Emitting Display，简称OLED)。在另一些实施例中，自发光显示装置为量子点电致发光显示装置(Quantum Dot Light-Emitting Display，简称QLED)。
如图2所示，在一些实施例中，数据处理顺序的确定方法具体通过如下步骤实现：
S10、根据本次检测周期内显示的多帧图像包含的多个像素中各种候选颜色的子像素的灰阶，确定本次检测周期内每种候选颜色的使用程度表征值。本次检测周期用于检测多个像素中选中颜色的子像素的预设检测参数，选中颜色为多种颜色中的一种，候选颜色为多种颜色中除选中颜色以外的颜色。
在一些实施例中，一种候选颜色的使用程度表征值用于表征多个像素中该候选颜色的各子像素被使用程度的总和。在另一些实施例中，一种候选颜色的使用程度表征值用于表征多个像素中该候选颜色的各子像素被使用程度的平均值。在另一些实施例中，一种候选颜色的使用程度表征值用于表征多个像素中该候选颜色的各子像素的灰阶与该候选颜色本身衰减率的关系。
应当理解到，每个检测周期都显示多帧图像，且各个检测周期显示的图像的帧数是相同的。示例的，本公开的一些实施例中提到的本次检测周期显示的图像帧数与下一检测周期显示的图像帧数相同。
此处，显示装置在显示图像时，由于显示内容不同，因此，各种候选颜色的使用程度表征值也不同。并且，在不同检测周期中，相同颜色的子像素的灰阶可能不同，进而不同检测周期中相同颜色的子像素的使用程度表征值也不同。
一种候选颜色的使用程度表征值，用于表征该候选颜色的使用程度，本领域技术人员应当理解到，候选颜色的子像素的灰阶越大，该候选颜色的使用程度表征值越大。使用程度表征值越大的候选颜色，该颜色的子像素的驱动晶体管老化的越快。
显示装置的一帧图像包括多个像素，在一些实施例中，多个像素 是显示装置中的所有像素。在另一些实施例中，多个像素是显示装置中的部分像素。即，在一些实施例中，一种候选颜色的使用程度表征值用于表征显示装置的所有像素中，该候选颜色的各个子像素被使用程度的总和。在另一些实施例中，一种候选颜色的使用程度表征值用于表征显示装置的部分像素中，该候选颜色的各个子像素被使用程度的总和。本领域的技术人员应当知道，在显示一帧图像时，显示装置中的多个像素是逐行显示的，在逐行显示时，由于相邻行之间的时间间隔非常短，因而在相邻行之间的间隔时间对选中颜色的子像素的预设检测参数进行检测不容易实现。因此，在一些实施中，在相邻两帧图像之间，对选中颜色的子像素的预设检测参数进行检测。考虑到，若在相邻两帧图像之间检测选中颜色的全部子像素的预设检测参数，又会导致相邻两帧图像的间隔时间较长，从而使得显示装置的显示效果非常差，因此，在不影响显示装置显示效果的前提下，在一些实施例中一个检测周期包括多帧图像，在多帧图像的显示时间内对选中颜色的全部子像素的预设检测参数进行分步检测。在一些实施例中，即在相邻两帧图像之间，对一行选中颜色的子像素的预设检测参数进行检测。
示例的，在一个检测周期内，对2160行的红色子像素进行检测，在该检测周期内显示2160帧图像，在每相邻两帧图像之间仅检测一行红色子像素的预设检测参数。
选中颜色的子像素的预设检测参数，用于表征选中颜色的子像素的老化程度。在一些实施例中，预设检测参数是驱动晶体管中阈值电压(Vth)的漂移程度。在另一些实施例中，预设检测参数是显示装置的显示亮度与电流的比值。
S20、根据检测顺序确定参数，从各种候选颜色中选择一种作为下一检测周期的选中颜色。检测顺序确定参数包括：本次检测周期内每种候选颜色的使用程度表征值。
对于采用何种方法从各种候选颜色中选择一种作为下一检测周期的选中颜色不进行限定。在一些实施例中，仅根据本次检测周期内每种候选颜色的使用程度表征值，来选择各种候选颜色中的一种作为下一检测周期的选中颜色。在另一些实施例中，根据本次检测周期内每 种候选颜色的使用程度表征值以及其它参考依据例如下文的上一检测周期的选中颜色，或者，各种所述候选颜色的优先级，共同来选取各种候选颜色中的一种作为下一检测周期的选中颜色。
在检测顺序确定参数包括：本次检测周期内每种所述候选颜色的使用程度表征值的情况下，在一些实施例中，从各种候选颜色中选择一种作为下一检测周期的选中颜色，包括：从各种候选颜色中选择使用程度表征值最大的颜色作为下一检测周期的选中颜色。
选择下一检测周期的选中颜色之后，对选中颜色的子像素进行数据处理。对选中颜色进行数据处理，包括：对选中颜色的子像素进行显示补偿处理。
在一些实施例中，对选中颜色的子像素进行显示补偿处理，包括：检测选中颜色的子像素的预设检测参数，根据预设检测参数对选中颜色的子像素进行补偿。在另一些实施例中，根据所述数据处理顺序，对选中颜色的子像素进行其它处理，此处不作限定。
每个检测周期只对选中颜色的子像素进行显示补偿处理，对于除选中颜色以外的其它颜色的子像素不进行显示补偿处理，只需给其它颜色的子像素输入根据显示图像计算得到的信号即可。示例的，对于一红色子像素和一蓝色子像素，根据一帧图像计算得到该红色子像素需要输入10V电压，蓝色子像素需要输入15V电压，红色子像素为本次检测周期的选中颜色，根据预设检测参数得到需要给红色子像素补充1V电压，因此在该帧图像显示时需要给红色子像素输入11V电压，蓝色子像素仍然输入15V电压。本公开的实施例提供一种数据处理顺序，用于确定显示多种颜色的显示装置中的选中颜色，由于在本次检测周期内，每种候选颜色的使用程度表征值与本次检测周期内显示的多帧图像包含的多个像素中各种候选颜色的子像素的灰阶有关，因此，根据本次检测周期内显示的多帧图像包含的多个像素中各种候选颜色的子像素的灰阶，确定本次检测周期内每种候选颜色的使用程度表征值，之后，再根据该检测周期内每种候选颜色的使用程度表征值，从候选颜色中选取一种颜色作为下一检测周期的选中颜色，并在下一检测周期对该选中颜色的子像素的预设检测参数进行检测，相对于相关技术，本公开实施例解决了相关技术中只能按照固定的颜色顺序对子 像素进行检测的问题。
在此基础上，在一个检测周期内，由于显示画面的不同，各种候选颜色的使用程度表征值不同，使用程度表征值越大的候选颜色，该颜色子像素的驱动晶体管老化的越快。例如，在一个检测周期内，红色子像素的使用程度表征值较大，那么，红色子像素中的驱动晶体管老化的较快，而其它颜色子像素中的驱动晶体管的老化不明显。采用相关技术中按照固定的颜色顺序对子像素进行检测的方法，则会出现来不及检测、补偿使用程度表征值较大的颜色的子像素，而将时间浪费在检测、补偿使用程度表征值较小的颜色的子像素上的问题。而采用本公开实施例提供的数据处理顺序的确定方法，对显示装置中的子像素进行检测，根据本次检测周期内每种候选颜色的使用程度表征值，来确定下一检测周期的选中颜色，并在下一检测周期对该选中颜色进行检测，由于一种候选颜色的使用程度表征值用于表征多个像素中该候选颜色的各子像素被使用程度的总和，因此，相较于相关技术，本公开实施例能够及时对使用程度表征值较高的颜色的子像素进行检测并补偿。
在一些实施例中，根据本次检测周期内显示的多帧图像包含的多个像素中各种候选颜色的子像素的灰阶，确定本次检测周期内每种候选颜色的使用程度表征值，如图3所示，具体通过如下步骤实现：
S101、根据一帧图像包含的多个像素中每种候选颜色的子像素的灰阶之和、以及预设灰阶范围与显示等级的对应关系，获取该帧图像中每种候选颜色的子像素对应的显示等级。
此处，先将一帧图像包含的多个像素中每种候选颜色的子像素的灰阶相加得到该帧图像包含的多个像素中每种候选颜色的子像素的灰阶之和，之后，再参考预设灰阶范围与显示等级的对应关系，得到每种候选颜色的子像素的灰阶之和对应的显示等级，进而得到该帧图像中每种候选颜色的子像素对应的显示等级。
示例的，本次检测周期包括2160帧图像，每帧图像包含1000个像素，1000个像素包括1000个红色子像素、1000个绿色子像素、1000个蓝色子像素、1000个白色子像素，若在本次检测周期对红色子像素进行检测，那么，候选颜色分别为绿色、蓝色、白色，获取2160帧图 像中1000个绿色子像素、1000个蓝色子像素、1000个白色子像素的灰阶，分别将一帧图像中1000个绿色子像素的灰阶相加得到1000个绿色子像素的灰阶之和，将一帧图像中1000个蓝色子像素的灰阶相加得到1000个蓝色子像素的灰阶之和，将一帧图像中1000个白色子像素的灰阶相加得到1000个白色子像素的灰阶之和，之后，参考预设灰阶范围与显示等级的对应关系，根据1000个绿色子像素的灰阶之和得到该帧图像中绿色子像素的显示等级，根据1000个蓝色子像素的灰阶之和得到该帧图像中蓝色子像素的显示等级，根据1000个白色子像素的灰阶之和得到该帧图像中白色子像素的显示等级。
不对预设灰阶范围与显示等级的对应关系进行限定，只要在合理的预设灰阶范围内，得到与一帧图像包含的多个像素中每种候选颜色的子像素的灰阶之和对应的显示等级即可。
本领域的技术人员应该知道，灰阶表示某种颜色的亮暗程度，在一些实施例中，例如划分为256级灰阶，即，每种颜色的灰阶的取值范围为0～255。灰阶为0表示亮度最小，灰阶为255表示亮度最大。
S102、累加本次检测周期内显示的多帧图像中每种候选颜色的子像素的显示等级，以得到本次检测周期内每种候选颜色的使用程度表征值。
示例的，候选颜色分别为绿色、蓝色、白色，在本次检测周期的2160帧图像中，绿色子像素的显示等级分别为x1、x2…x2159、x2160，蓝色子像素的显示等级分别为y1、y2…y2159、y2160，白色子像素的显示等级分别为z1、z2…z2159、z2160，经过累加得到2160帧图像中绿色子像素的显示等级之和Sx＝x1+x2+…+x2159+x2160，2160帧图像中蓝色子像素的显示等级之和Sy＝y1+y2+…+y2159+y2160，2160帧图像中白色子像素的显示等级之和Sz＝z1+z2+…+z2159+z2160，之后，再根据Sx得到绿色子像素的使用程度表征值、根据Sy得到蓝色子像素的使用程度表征值、根据Sz得到白色子像素的使用程度表征值。
本公开的一些实施例中，本次检测周期包括多帧图像，通过计算一帧图像内包含的多个像素中每种候选颜色的子像素的灰阶之和，根据每种候选颜色的子像素的灰阶之和、以及预设灰阶范围与显示等级的对应关系，得到一帧图像中每种候选颜色的子像素对应的显示等级， 之后，再将多帧图像中每种候选颜色的子像素的显示等级进行累加，得到本次检测周期内每种候选颜色的使用程度表征值，该方法简单有效的根据本次检测周期内显示的多帧图像包含的多个像素中各种候选颜色的子像素的灰阶，确定出本次检测周期内每种候选颜色的使用程度表征值。
在一些实施例中，根据一帧图像包含的多个像素中每种候选颜色的子像素的灰阶之和、以及预设灰阶范围与显示等级的对应关系，获取该帧图像中每种候选颜色的子像素对应的显示等级，包括：
在一帧图像包含的多个像素中候选颜色的子像素的灰阶大于或等于q的个数处于0～m范围的情况下，若一帧图像包含的多个像素中候选颜色的子像素的灰阶之和处于
Figure PCTCN2019072750-appb-000007
范围时，则该候选颜色的子像素的显示等级为a；若一帧图像包含的多个像素中候选颜色的子像素的灰阶之和处于
Figure PCTCN2019072750-appb-000008
范围时，则该候选颜色的子像素的显示等级为b；若一帧图像包含的多个像素中候选颜色的子像素的灰阶之和处于
Figure PCTCN2019072750-appb-000009
范围时，则该候选颜色的子像素的显示等级为c；若一帧图像包含的多个所述像素中候选颜色的子像素的灰阶之和处于
Figure PCTCN2019072750-appb-000010
范围时，则该候选颜色的子像素的显示等级为d。n为多个像素的个数，m的范围为多个像素个数的1％～10％，即m的范围为1％n～10％n，a＜b＜c＜d，q≥200。在一帧图像包含的多个像素中候选颜色的子像素的灰阶大于或等于q的个数处于m～n范围的情况下，候选颜色的子像素的显示等级为d。
为了计算简单，在一些实施例中，a为0，b为1，c为2，d为3。
本领域的技术人员应该知道，在未规定相邻区间的分界点属于所述分界点以左的区间或所述分界点以右的区间的情况下，在一些实施例中，相邻区间的分界点属于分界点以左的区间，在另一些实施例中，相邻区间的分界点属于分界点以右的区间。本领域技术人员应该明白， 所述分界点不同时属于由其界定的相邻两个区间。
因此，本公开的一些实施例中“一帧图像包含的多个像素中候选颜色的子像素的灰阶大于或等于q的个数处于0～m范围”是指：一帧图像包含的多个像素中候选颜色的子像素的灰阶大于、或大于等于q的个数处于[0，m)或[0，m]范围。相应的，“一帧图像包含的多个像素中候选颜色的子像素的灰阶大于或等于q的个数处于m～n范围”是指：一帧图像包含的多个像素中候选颜色的子像素的灰阶大于、或大于等于q的个数处于[m，n]或(m，n]范围。此处，在前者候选颜色的子像素的灰阶大于、或大于等于q的个数处于[0，m)范围的情况下，后者候选颜色的子像素的灰阶大于、或大于等于q的个数处于[m，n]范围。在前者候选颜色的子像素的灰阶大于、或大于等于q的个数处于[0，m]范围的情况下，后者候选颜色的子像素的灰阶大于、或大于等于q的个数处于(m，n]范围。

虽然n表示一帧图像中多个像素的个数，但本领域的技术人员应该知道，一个像素中包括多种颜色的子像素，每个像素中某一颜色的子像素的个数为1，即像素的个数与某一颜色的子像素的个数相同，因此，n也表示一帧图像中多个像素中某一候选颜色的子像素的个数。
如图4(e)所示，一帧图像包含的n个像素中某一候选颜色的子像 素的灰阶之和为255n，255表示一帧图像包含的某一候选颜色的1个子像素的灰阶为255，255n是某一候选颜色的n个子像素均为最大亮度时的灰阶之和。如图4(d)所示，一帧图像包含的n个像素中某一候选颜色的子像素的灰阶之和为
Figure PCTCN2019072750-appb-000028
即为该候选颜色的n个子像素的灰阶之和为最大亮度时的灰阶之和的3/4。如图4(c)所示，一帧图像包含的n个像素中某一候选颜色的子像素的灰阶之和为
Figure PCTCN2019072750-appb-000029
即为该候选颜色的n个子像素的灰阶之和为最大亮度时的灰阶之和的1/2。如图4(b)所示，一帧图像包含的n个像素中某一候选颜色的子像素的灰阶之和为
Figure PCTCN2019072750-appb-000030
即为该候选颜色的n个子像素的灰阶之和为最大亮度时的灰阶之和的1/4。如图4(a)所示，一帧图像包含的n个像素中某一候选颜色的子像素的灰阶之和为0，即为n个某一候选颜色的子像素均为最小亮度时的灰阶之和。
对于候选颜色的n个子像素中每个子像素的灰阶不进行限定，图4(b)仅示出了某一候选颜色的n/4个子像素的灰阶为255，其余3n/4个子像素的灰阶为0，但不并限于此，以候选颜色的n个子像素的灰阶之和为
Figure PCTCN2019072750-appb-000031
为准。当然，某一候选颜色的n个子像素不一定全部集中在n个像素组成的一帧图像的一个区域、也不一定在该区域内该候选颜色的所有子像素的灰阶均为255，某一候选颜色中具有一定灰阶值的子像素的分布位置及灰阶值，均以显示装置10的实际显示内容为准。同样的，图4(c)、图4(d)、图4(e)示出的某一候选颜色中具有一定灰阶值的子像素的分布位置、及灰阶值，也以显示装置10的实际显示内容为准，在此不再赘述。
本公开的实施例中，根据一帧图像包含的多个像素中候选颜色的子像素的灰阶大于或等于q的个数的不同，将计算候选颜色的子像素 的显示等级的方法分为两种，当一帧图像包含的多个像素中候选颜色的子像素的灰阶大于或等于q的个数处于0～m范围，按照一帧图像包含的多个像素中候选颜色的子像素的灰阶之和的取值范围，将多个像素中候选颜色的子像素的灰阶之和均分为4等份(即，预设灰阶范围)，并判断在显示装置10实际显示内容时，一帧图像包含的多个像素中候选颜色的子像素的灰阶之和所处的预设灰阶范围，之后，根据灰阶之和所处的预设灰阶范围，得到该帧图像包含的多个像素中每种候选颜色的子像素对应的显示等级为a或b或c或d。当一帧图像包含的多个像素中候选颜色的子像素的灰阶大于或等于q的个数处于m～n范围，直接判定该候选颜色的子像素的显示等级为d。该方法计算简单，根据一帧图像包含的多个像素中每种候选颜色的子像素的灰阶之和、以及预设灰阶范围与显示等级的对应关系，准确地获取该帧图像每种候选颜色的子像素对应的显示等级。
在一些实施例中，根据检测顺序确定参数，从各种候选颜色中选择一种作为下一检测周期的选中颜色，包括：
采用第一阈值、第二阈值对本次检测周期内候选颜色的使用程度表征值的取值范围进行划分，得到第一区间、第二区间、第三区间，第一区间、第二区间、第三区间的使用程度表征值依次逐渐减小；第一阈值为第一区间和第二区间的分界点，第二阈值为第二区间和第三区间的分界点，第一阈值大于第二阈值。若各种候选颜色的使用程度表征值有处于第一区间的，则选取使用程度表征值处于第一区间的候选颜色中的一种作为下一检测周期的选中颜色；若各种候选颜色的使用程度表征值均处于第二区间、或第二区间和第三区间，则选取使用程度表征值处于第二区间的候选颜色中的一种作为下一检测周期的选中颜色；若各种候选颜色的使用程度表征值均处于第三区间，则选取候选颜色中的一种作为下一检测周期的选中颜色。
示例的，假设本次检测周期对红色子像素进行检测，候选颜色分别为绿色、蓝色、白色，若只有绿色的使用程度表征值处于第一区间，则选取绿色作为下一检测周期的选中颜色。若绿色、白色的使用程度表征值均处于第一区间，则选取绿色或白色中的一种作为下一检测周期的选中颜色。
假设本次检测周期对红色子像素进行检测，候选颜色分别为绿色、蓝色、白色，在绿色、蓝色、白色的使用程度表征值均不处于第一区间的情况下，若只有绿色的使用程度表征值处于第二区间，蓝色和白色的使用程度表征值处于第三区间，则选取绿色作为下一检测周期的选中颜色；若绿色、白色的使用程度表征值均处于第二区间，蓝色的使用程度表征值处于第三区间，则可以选取绿色或白色中的一种作为下一检测周期的选中颜色。
假设本次检测周期对红色子像素进行检测，候选颜色分别为绿色、蓝色、白色，若绿色、蓝色、白色的使用程度表征值均处于第三区间，则可以选取绿色或蓝色或白色中的一种作为下一检测周期的选中颜色。
在一些实施例中，在本次检测周期内，第一阈值和第二阈值是候选颜色的使用程度表征值的取值范围中的任意两个值，只要第一阈值大于第二阈值即可。但考虑到要根据第一阈值和第二阈值划分得到的第一区间、第二区间、第三区间选取下一检测周期的选中颜色，因此，第一阈值和第二阈值应为合理的数值。例如，第一阈值、第二阈值将本次检测周期内候选颜色的使用程度表征值的取值范围划分为均等的三部分。
本次检测周期内候选颜色的使用程度表征值的最大值、第一阈值、第二阈值、本次检测周期内一候选颜色的使用程度表征值的最小值依次减小。由本次检测周期内一候选颜色的使用程度表征值的最大值与第一阈值界定出第一区间，由第一阈值与第二阈值界定出第二区间，由第二阈值与本次检测周期内一候选颜色的使用程度表征值的最小值界定出第三区间。
在一些实施例中，第一阈值属于第一区间。在另一些实施例中，第一阈值属于第二区间。在一些实施例中，第二阈值属于第二区间。在另一些实施例中，第二阈值属于第三区间。并且，第一区间、第二区间、第三区间之间两两无交集。
不对获取各种候选颜色的使用表征值的顺序进行限定，在一些实施例中，同时获取不同候选颜色的使用程度表征值，在另一些实施例中依次获取不同候选颜色的使用程度表征值。此处，依次获取不同候 选颜色的使用程度表征值，在一些实施例，按照一定的顺序，依次获取不同候选颜色的使用程度表征值；在另一些实施例中采用随机的方式，依次获取不同候选颜色的使用程度表征值。
在依次获取不同候选颜色的使用程度表征值的情况下，在一些实施例中，若获取的第一种候选颜色的使用程度表征值处于第一区间，则直接选取该候选颜色作为下一检测周期的选中颜色，无需获取其它候选颜色的使用程度表征值。在另一些实施例中，在获取第一种候选颜色的使用程度表征值处于第一区间后，继续获取其它候选颜色的使用程度表征值，若还有其它候选颜色的使用程度表征值处于第一区间，则在处于第一区间的所有候选颜色中选取一种作为下一检测周期的选中颜色。
本公开的一些实施例中，通过判断在本次检测周期内，每种候选颜色的使用程度表征值处于第一区间或第二区间或第三区间，来选取候选颜色中的一种作为下一检测周期的选中颜色，方法简单易实施。
在一些实施例中，检测顺序确定参数还包括：上一检测周期的选中颜色。根据检测顺序确定参数，从各种候选颜色中选择一种作为下一检测周期的选中颜色，包括：采用第一阈值、第二阈值对本次检测周期内候选颜色的使用程度表征值的取值范围进行划分，得到第一区间、第二区间、第三区间，第一区间、第二区间、第三区间的使用程度表征值依次逐渐减小。第一阈值为第一区间和第二区间的分界点，第二阈值为第二区间和第三区间的分界点，第一阈值大于第二阈值。在各种候选颜色的使用程度表征值有处于第一区间的情况下，若使用程度表征值处于第一区间的候选颜色包括上一检测周期的选中颜色和除上一检测周期的选中颜色以外的其它颜色，则选取使用程度表征值处于第一区间的候选颜色中除上一检测周期的选中颜色以外的其它颜色中的一种作为下一检测周期的选中颜色；若使用程度表征值处于第一区间的候选颜色不包括上一检测周期的选中颜色，则选取使用程度表征值处于第一区间的候选颜色中的一种作为下一检测周期的选中颜色；若使用程度表征值处于第一区间的候选颜色为上一检测周期的选中颜色，则选取上一检测周期的选中颜色作为下一检测周期的选中颜色。
示例的，假设上一检测周期的选中颜色为绿色，本次检测周期对红色子像素进行检测，本次检测周期的候选颜色分别为绿色、蓝色、白色，若绿色、白色的使用程度表征值均处于第一区间，则选取白色作为下一检测周期的选中颜色。
假设上一检测周期的选中颜色为绿色，本次检测周期对红色子像素进行检测，本次检测周期的候选颜色分别为绿色、蓝色、白色，若只有蓝色的使用程度表征值处于第一区间，则选取蓝色作为下一检测周期的选中颜色；若蓝色、白色的使用程度表征值均处于第一区间，则选取蓝色或白色中的一种作为下一检测周期的选中颜色。
假设上一检测周期的选中颜色为绿色，本次检测周期对红色子像素进行检测，本次检测周期的候选颜色分别为绿色、蓝色、白色，若只有绿色的使用程度表征值处于第一区间，则选取绿色作为下一检测周期的选中颜色。
在各种候选颜色的使用程度表征值均处于第二区间、或第二区间和第三区间的情况下，若使用程度表征值处于第二区间的候选颜色包括上一检测周期的选中颜色和除上一检测周期的选中颜色以外的其它颜色，则选取使用程度表征值处于第二区间的候选颜色中除上一检测周期的选中颜色以外的其它颜色中的一种作为下一检测周期的选中颜色；若使用程度表征值处于第二区间的候选颜色不包括上一检测周期的选中颜色，则选取使用程度表征值处于第二区间的候选颜色中的一种作为下一检测周期的选中颜色；若使用程度表征值处于第二区间的候选颜色为上一检测周期的选中颜色，则选取上一检测周期的选中颜色作为下一检测周期的选中颜色。
示例的，假设上一检测周期的选中颜色为绿色，本次检测周期对红色子像素进行检测，本次检测周期的候选颜色分别为绿色、蓝色、白色，在绿色、蓝色、白色的使用程度表征值均不处于第一区间的情况下，若绿色、白色的使用程度表征值均处于第二区间，蓝色的使用程度表征值处于第三区间，则选取白色作为下一检测周期的选中颜色。
假设上一检测周期的选中颜色为绿色，本次检测周期对红色子像素进行检测，本次检测周期的候选颜色分别为绿色、蓝色、白色，在绿色、蓝色、白色的使用程度表征值均不处于第一区间的情况下，若 只有蓝色的使用程度表征值处于第二区间，则选取蓝色作为下一检测周期的选中颜色，或者若只有白色的使用程度表征值处于第二区间，则选取白色作为下一检测周期的选中颜色；若蓝色、白色的使用程度表征值均处于第二区间，绿色的使用程度表征值处于第三区间，则选取蓝色或白色中的一种作为下一检测周期的选中颜色。
假设上一检测周期的选中颜色为绿色，本次检测周期对红色子像素进行检测，本次检测周期的候选颜色分别为绿色、蓝色、白色，若只有绿色的使用程度表征值处于第二区间，蓝色和白色的使用程度表征值处于第三区间，则选取绿色作为下一检测周期的选中颜色。
在各种候选颜色的使用程度表征值均处于第三区间的情况下，则选取候选颜色中除上一检测周期的选中颜色以外的其它颜色中的一种作为下一检测周期的选中颜色。假设上一检测周期的选中颜色为绿色，本次检测周期对红色子像素进行检测，本次检测周期的候选颜色分别为绿色、蓝色、白色，若绿色、蓝色、白色的使用程度表征值均处于第三区间，则选取蓝色或白色中的一种作为下一检测周期的选中颜色。
由于上述已经对第一阈值和第二阈值的选取以及第一区间、第二区间、第三区间的划分进行了详细的描述，因而此处不再赘述。
不对获取各种候选颜色的使用表征值的顺序进行限定，在一些实施例中，同时获取不同候选颜色的使用程度表征值，在另一些实施例中，依次获取不同候选颜色的使用程度表征值。此处，依次获取不同候选颜色的使用程度表征值，在一些实施例，按照一定的顺序，依次获取不同候选颜色的使用程度表征值；在另一些实施例中采用随机的方式，依次获取不同候选颜色的使用程度表征值。
在依次获取不同候选颜色的使用程度表征值的情况下，在一些实施例中，若获取的第一种候选颜色的使用程度表征值处于第一区间、且第一种候选颜色不是上一检测周期的选中颜色，则可以直接选取该候选颜色作为下一检测周期的选中颜色，无需获取其它候选颜色的使用程度表征值。在另一些实施例在，若获取的第一种候选颜色的使用程度表征值处于第一区间、但第一种候选颜色是上一检测周期的选中颜色，则需继续获取其它候选颜色的使用程度表征值，并判断其它候选颜色的使用程度表征值所处的区间。
当然，在各种候选颜色的使用程度表征值有处于第一区间的情况下，若第一种候选颜色不是上一检测周期的选中颜色，在获取第一种候选颜色的使用程度表征值处于第一区间后，继续获取其它候选颜色的使用程度表征值，若还有其它候选颜色的使用程度表征值处于第一区间，在处于第一区间的所有候选颜色中选取一种作为下一检测周期的选中颜色。
本公开的一些实施例，在上一检测周期的选中颜色和除上一检测周期以外的其它候选颜色，均可作为下一检测周期的选中颜色的情况下，优先选取除上一检测周期以外的其他候选颜色作为下一检测周期的选中颜色，由于在上一检测周期已经检测过上一检测周期的选中颜色，因此，相较于仅考虑每种候选颜色的使用程度表征值的方案，本公开的实施例的确定方式更加及时检测每一个使用程度表征值较高的候选颜色。
在一些实施例中，检测顺序确定参数还包括：各种候选颜色的优先级，各种候选颜色的优先级中，上一检测周期的选中颜色的优先级最低。根据检测顺序确定参数，从各种候选颜色中选择一种作为下一检测周期的选中颜色，包括：采用第一阈值、第二阈值对本次检测周期内候选颜色的使用程度表征值的取值范围进行划分，得到第一区间、第二区间、第三区间，第一区间、第二区间、第三区间的使用程度表征值依次逐渐减小。第一阈值为第一区间和第二区间的分界点，第二阈值为第二区间和第三区间的分界点，第一阈值大于第二阈值。
按照各种候选颜色的优先级依次确定各种候选颜色的使用程度表征值所处的区间；若确定出一个候选颜色的使用程度表征值处于第一区间，则选取该候选颜色作为下一检测周期的选中颜色；若各种候选颜色的使用程度表征值均处于第二区间、或第二区间和第三区间，则选取使用程度表征值处于第二区间的候选颜色中优先级最高的作为下一检测周期的选中颜色；若各种候选颜色的使用程度表征值均处于第三区间，则选取候选颜色中优先级最高的作为下一检测周期的选中颜色。
示例的，假设上一检测周期的选中颜色为绿色，本次检测周期对红色子像素进行检测，各种候选颜色的优先级顺序为蓝色、白色、绿 色，如图5(a)所示，若获取的蓝色的使用程度表征值处于第一区间，则直接选取蓝色作为下一检测周期的选中颜色，无需获取白色、绿色的使用程度表征值；如图5(b)所示，若蓝色的使用程度表征值处于第二区间、白色的使用程度表征值处于第一区间，则选取白色作为下一检测周期的选中颜色，无需获取绿色的使用程度表征值；如图5(c)所示，若蓝色、白色的使用程度表征值均处于第二区间、绿色的使用程度表征值处于第一区间，则选取绿色作为下一检测周期的选中颜色。
示例的，假设上一检测周期的选中颜色为绿色，本次检测周期对红色子像素进行检测，各种候选颜色的优先级顺序为蓝色、白色、绿色，在蓝色、白色、绿色的使用程度表征值均不处于第一区间的情况下，如图6(a)所示，若只有蓝色的使用程度表征值处于第二区间，则选取蓝色作为下一检测周期的选中颜色；如图6(b)所示，若蓝色和白色的使用程度表征值处于第二区间、绿色的使用程度表征值处于第三区间，则仍选取蓝色作为下一检测周期的选中颜色；如图6(c)所示，若只有白色的使用程度表征值处于第二区间，则选取白色作为下一检测周期的选中颜色；如图6(d)所示，若蓝色的使用程度表征值处于第三区间、白色和绿色的使用程度表征值处于第二区间，则选取白色作为下一检测周期的选中颜色；如图6(e)所示，若只有绿色的使用程度表征值处于第二区间，则选取绿色作为下一检测周期的选中颜色。
示例的，假设上一检测周期的选中颜色为绿色，本次检测周期对红色子像素进行检测，各种候选颜色的优先级顺序为蓝色、白色、绿色，如图7所示，在蓝色、白色、绿色的使用程度表征值均处于第三区间的情况下，选取蓝色作为下一检测周期的选中颜色。
由于上述已经对第一阈值和第二阈值的选取以及第一区间、第二区间、第三区间的划分进行了详细的描述，因而此处不再赘述。
在本公开的一些实施例中，按照各种候选颜色的优先级，依次获取不同候选颜色的使用程度表征值。
若获取的优先级最高的候选颜色的使用程度表征值处于第一区间，则直接选取该候选颜色作为下一检测周期的选中颜色，无需获取其他候选颜色的使用程度表征值。当然，在获取的优先级最高的候选颜色的使用程度表征值不处于第一区间的情况下，应继续获取其他候 选颜色的使用程度表征值。
由于对于任意两个检测周期来说，上一检测周期的选中颜色及本次检测周期的选中颜色可能不相同，因此，不同检测周期的各种候选颜色的优先级也不相同。
示例的，假设各种候选颜色的优先级的初始排序是：红色、绿色、蓝色、白色，第一个检测周期的选中颜色为红色，第二个检测周期的选中颜色为白色，第三个检测周期的选中颜色为蓝色，第四个检测周期的选中颜色为绿色，当以第二个检测周期作为本次检测周期时，本次检测周期的候选颜色的预设检测顺序为：绿色、蓝色、红色；当以第三个检测周期作为本次检测周期时，本次检测周期的候选颜色的预设检测顺序为：红色、绿色、白色；当以第四个检测周期作为本次检测周期时，本次检测周期的候选颜色的预设检测顺序为：红色、白色、蓝色。
上述的第一个检测周期、第二个检测周期、第三个检测周期、第四个检测周期，两两之间无其它检测周期。
本公开的一些实施例，按照各种候选颜色的优先级依次确定各种候选颜色的使用程度表征值所处的区间，在上一检测周期的选中颜色和除上一检测周期以外的其它候选颜色，均可作为下一检测周期的选中颜色的情况下，优先选取除上一检测周期以外的其它候选颜色作为下一检测周期的选中颜色。在此基础上，在各种候选颜色的优先级中排在优先位置的候选颜色处于第一区间的情况下，不再获取其他候选颜色的使用程度表征值，相较于仅考虑每种候选颜色的使用程度表征值的方案，本公开实施例的确定方式更加及时检测每一个使用程度表征值较高的候选颜色、且更加节省获取候选颜色的使用程度表征值的时间；相较于考虑每种候选颜色的使用程度表征值、及上一检测周期的选中颜色的方案，本公开实施例的确定方式更加节省获取候选颜色的使用程度表征值的时间。
在一些实施例中，第一阈值为
Figure PCTCN2019072750-appb-000032
第二阈值为
Figure PCTCN2019072750-appb-000033
P为检测周期内的图像帧数与显示等级的最大值的乘积；显示等级分为0级，1级，2级和3级。
此处，由前述实施例可知，一个检测周期包括多帧图像，累加多帧图像中某一候选颜色的子像素的显示等级，即可得到本次检测周期内某一候选颜色的使用程度表征值。
若本次检测周期内具有2160帧图像，则每种候选颜色的使用程度表征值的取值范围为2160×0～2160×3，即，0～2160×3。第一阈值Level＝2160×2，第二阈值Leve2＝2160×1。
在一些实施例中，第一区间的取值范围为2160×2～2160×3，第二区间的取值范围为2160×1～2160×2，第三区间的取值范围为0～2160×1。
当然，第一区间与第二区间之间无交集、第二区间与第三区间之间无交集。
在本公开的一些实施例中，通过使第一阈值等于某一候选颜色的使用程度表征值最大值的

第二阈值等于某一候选颜色的使用程度表征值最大值的
Figure PCTCN2019072750-appb-000035
采用第一阈值、第二阈值对某一候选颜色的使用程度表征值的取值范围进行均等划分，得到第一区间、第二区间、第三区间计算简单。
本公开的一些实施例提供一种显示装置10的显示方法，包括根据前述任一实施例所述的确定方法确定下一检测周期的选中颜色，如图8所示，所述显示方法还包括如下步骤：
S30、在下一检测周期，检测选中颜色的子像素的预设检测参数。
选中颜色的子像素的预设检测参数，用于表征选中颜色的子像素中驱动晶体管的老化程度。在一些实施例中，预设检测参数是驱动晶体管中阈值电压的漂移程度。在另一些实施例中，预设检测参数是显示装置10的显示亮度与电流的比值。
S40、根据测得的选中颜色的子像素的预设检测参数，判断是否对选中颜色的子像素进行补偿；若是，则对选中颜色的子像素进行补偿；否则，无需对选中颜色的子像素进行补偿。
若需要对选中颜色的子像素进行补偿，则在本次检测周期后，显示装置10显示一帧图像或多帧图像的同时进行补偿。
本公开的一些实施例提供一种显示装置10的显示方法，具有与前述数据处理顺序的确定方法相同的技术效果，在此不再赘述。

在一些实施例中，当指令被处理器12执行时，使得处理器12还执行以下步骤：在一帧图像包含的多个像素中候选颜色的子像素的灰阶大于或等于q的个数处于0～m的情况下，若一帧图像包含的多个像素中候选颜色的子像素的灰阶之和处于

范围时，则该候选颜色的子像素的显示等级为d。n为多个所述像素的个数，m为多个像素个数的1％～10％，a＜b＜c＜d，q≥200。
在一帧图像包含的多个像素中候选颜色的子像素的灰阶大于或等于q的个数处于m～n范围的情况下，确定候选颜色的子像素的所述显示等级为d。
为了计算简单，在一些实施例中，a为0，b为1，c为2，d为3。
在一些实施例中，当指令被处理器12执行时，使得处理器12还执行以下步骤：采用第一阈值、第二阈值对本次检测周期内候选颜色的使用程度表征值的取值范围进行划分，得到第一区间、第二区间、第三区间，第一区间、第二区间、第三区间的使用程度表征值依次逐渐减小。
若各种候选颜色的使用程度表征值有处于第一区间的，则选取使用程度表征值处于第一区间的候选颜色中的一种作为下一检测周期的选中颜色；若各种候选颜色的使用程度表征值均处于所述第二区间、或第二区间和所述第三区间，则选取使用程度表征值处于第二区间的候选颜色中的一种作为下一检测周期的选中颜色；若各种候选颜色的使用程度表征值均处于第三区间，则选取候选颜色中的一种颜色作为下一检测周期的选中颜色；第一阈值为第一区间和第二区间的分界点，第二阈值为第二区间和第三区间的分界点，第一阈值大于第二阈值。

在各种候选颜色的使用程度表征值有处于第一区间的情况下，若使用程度表征值处于第一区间的候选颜色包括上一检测周期的选中颜 色和除上一检测周期的选中颜色以外的其它颜色，则选取使用程度表征值处于第一区间的候选颜色中除上一检测周期的选中颜色以外的其它颜色中的一种作为下一检测周期的选中颜色；若使用程度表征值处于第一区间的候选颜色不包括上一检测周期的选中颜色，则选取使用程度表征值处于第一区间的候选颜色中的一种作为下一检测周期的选中颜色；若使用程度表征值处于第一区间的候选颜色为上一检测周期的选中颜色，则选取上一检测周期的选中颜色作为下一检测周期的选中颜色。
在各种候选颜色的使用程度表征值均处于第二区间、或第二区间和第三区间的情况下，若使用程度表征值处于第二区间的候选颜色包括上一检测周期的选中颜色和除上一检测周期的选中颜色以外的其它颜色，则选取使用程度表征值处于第二区间的候选颜色中除上一检测周期的选中颜色以外的其它颜色中的一种作为下一检测周期的选中颜色；若使用程度表征值处于第二区间的候选颜色不包括上一检测周期的选中颜色，则选取使用程度表征值处于第二区间的候选颜色中的一种作为下一检测周期的选中颜色；若使用程度表征值处于第二区间的候选颜色为上一检测周期的选中颜色，则选取上一检测周期的选中颜色作为下一检测周期的选中颜色。
