基于上述硬件结构，提出本申请方法实施例。
参照图2，在本申请AMOLED显示残影消除方法第一实施例中，所述AMOLED显示残影消除方法包括：
步骤S10，检测到AMOLED显示面板上电时，对所述显示面板的第一持续上电时长进行计时；
在检测到AMOLED显示面板上电时，从该时刻起，对显示面板的第一持续上电时长进行计时；其中，这里的显示面板上电，是指AMOLED显示面板已经具备消除显示残影的功能，用户在正常使用时的显示面板上电；第一持续上电时长是指，从AMOLED显示面板上电的这一个时刻算起，AMOLED显示面板保持通电状态的后续每一个时刻，已经保持通电状态的总时长；例如，在上午7:00，检测到AMOLED显示面板上电，AMOLED显示面板保持通电状态到上午7:50，那么在7:00~7:50之间都对显示面板的持续上电时长进行计时，在7:00~7:50之间的任一时刻都有对应的一个持续上电时长。
步骤S20，根据所述第一持续上电时长，获取对应的各个TFT的各个灰阶补偿值；
在每个不同的时刻，根据对应的第一持续上电时长在预设时间区段表中的实时时间区段，获取到在这个实时时间区段内对应各个TFT的各个灰阶补偿值；其中，AMOLED显示面板上有多个像素点，每个像素点处都有一个TFT，通过TFT上的控制信号可以控制TFT驱动电流的通断，进而控制像素点发光；对应的各个TFT的各个灰阶补偿值是指，每个TFT都有一个对应的灰阶补偿值，并且不同持续上电时长每个TFT对应的灰阶补偿值不同，需要根据持续上电时长确定对应的TFT对应的灰阶补偿值；例如，第一持续上电时长为5-10分钟时，对应的灰阶补偿值为3，第一持续上电时长为11-15分钟时，对应的灰阶补偿值为4，第一持续上电时长为15-20分钟时，对应的灰阶补偿值为5。
步骤S30，根据所述各个灰阶补偿值，调整所述显示面板上对应的各个TFT的驱动电流。
获取到第一持续上电时长对应的各个TFT的各个灰阶补偿值后；在当前的第一持续上电时长下，不同的显示灰阶下各个TFT对应的灰阶补偿值都不同，需要获取各个TFT的显示数据，并根据各个TFT的显示数据确定当前的显示灰阶；从而进一步确定在当前的第一持续上电时长下，当前的显示灰阶对应的各个TFT的各个灰阶补偿值；然后根据确定各个TFT的各个灰阶补偿值，对对应各个TFT的显示数据进行补偿，并将补偿后的显示数据转换得到补偿后的驱动数据，补偿后的驱动数据驱动各个TFT产生驱动电流，从而达到调整显示面板上对应的各个TFT的驱动电流的目的；例如，显示面板有高、中、低三个亮度，在第一持续上电时长为15分钟时，每个TFT在高、中、低三个不同亮度下对应灰阶补偿值分别为3、4、5，那么确定了第一持续上电时长为15分钟后，就需要确定各个TFT对应的是高、中、低三个亮度中哪一个亮度，从而确定每个TFT的灰阶补偿值是3、4、5中的哪一个。
其中，各个TFT的驱动电流是指，AMOLED显示面板上有多个像素点，每个像素点处都有一个TFT，每个TFT都有一个对应的驱动数据，每个TFT对应的驱动数据驱动TFT产生驱动电流；例如，AMOLED显示面板上有i行、j列个像素点，那么有i乘以j个TFT，与每个TFT对应的i乘以j个驱动数据，在每个驱动数据驱动下产生的i乘以j个驱动电流。
在本实施例中，用户在正常上电使用AMOLED显示面板时，通过统计不同的持续上电时长来确定不同的灰阶补偿值，TFT在不同的持续上电时长会发生不同程度的温漂；在不同的持续上电时长获取不同的灰阶补偿值对发生不同程度温漂的TFT对应的显示数据进行补偿；避免了采用单一补偿值，只能在上电前的一小段时间消除残影，使得在很长持续上电时间流过各个TFT的驱动电流保持不变，解决了AMOLED在持续上电时长下发热产生温漂，因温漂引起各个TFT的驱动电流发生改变而产生显示残影的问题。
参照图3，在本申请AMOLED显示残影消除方法第二实施例中，基于上述图2所示的实施例，步骤S20的包括：
步骤S21，动态获取所述第一持续上电时长在预设时间区段表中的时间区段；
为了方便理解，举例进行说明，例如，预设时间区段表在0-15分钟内有三个时间区段，第一持续上电时长在0-5分钟内为一个实时时间区段，在6-10分钟内为一个实时时间区段，在11-15分钟内为一个实时时间区段；动态获取是指，获取第一持续上电时长在0-15分钟每一个时长；当获取到的第一持续上电时长为1分钟时，那么第一持续上电时长在预设时间区段表中的实时时间区段为0-5分钟实时时间区段；当获取到的第一持续上电时长为9分钟时，那么第一持续上电时长在预设时间区段表中的实时时间区段为6-10分钟实时时间区段。
步骤S22，根据所述实时时间区段，从预设灰阶补偿值集合中动态提取对应的各个TFT的各个灰阶补偿值。
根据动态获取到第一持续上电时长落入的实时时间区段，从预设的灰阶补偿值集合中，找到对应实时时间区段的各个TFT的各个灰阶补偿值；当没有找到与第一持续上电时长对应的实时时间区段时，采用与第一持续上电时长最接近的时间对应的实时时间区段，提取各个TFT的各个灰阶补偿值；其中，预设灰阶补偿值集合，是指各个TFT第一持续上电时长在同一个实时时间区段下，不同的显示灰阶，都有一个对应的灰阶补偿值；各个TFT在同一个显示灰阶，第一持续上电时长在不同的实时时间区段下，也都有一个对应的灰阶补偿值；各个TFT在不同第一持续上电时长、不同显示灰阶下对应的所有灰阶补偿值构成预设灰阶补偿值集合。
为了方便理解，接步骤S21的例子进行说明，第一持续上电时长在0-5分钟内的一个实时时间区段，有高、中、低三种不同的显示灰阶，各个TFT在高、中、低三种不同的显示灰阶对应灰阶补偿值分别为2、3、4；在6-10分钟内的一个实时时间区段，有高、中、低三种不同的显示灰阶，各个TFT在高、中、低三种不同的显示灰阶对应灰阶补偿值分别为5、6、7；在11-15分钟内的一个实时时间区段，有高、中、低三种不同的显示灰阶，各个TFT在高、中、低三种不同的显示灰阶对应灰阶补偿值分别为8、9、10；那么预设的灰阶补偿值集合包括2、3、4、5、6、7、8、9、10这九个灰阶补偿值，如果确定第一持续上电时长落入0-5分钟内的实时时间区段，那么从预设灰阶补偿值集合获取到各个TFT的各个灰阶补偿值分别为2、3、4；如果第一持续上电时长为17分钟，在预设时间区段表找不到对应的实时时间区段，此时采用0-15分钟的实时时间区段对应各个灰阶补偿值8、9、10。
在本实施例中，用户在正常上电使用AMOLED显示面板后，通过动态获取各个TFT在不同第一持续上电时长后，确定动态的第一持续上电时长在预设时间区段表中的时间区段，然后在预设灰阶补偿值集中动态提取对应的各个TFT的各个灰阶补偿值；通过不同的第一持续上电时长提取不同的灰阶补偿值，针对TFT在不同的持续上电时长下产生不同程度温漂，使得补偿更优针对性，有效地解决了不同持续上电时长带来的残影问题。
进一步地，所述S30的步骤包括：
步骤S31，获取各个TFT的各个显示数据；
步骤S32，根据各个显示数据确定当前的显示灰阶；
步骤S33，将各个TFT的各个显示数据与当前的显示灰阶对应的各个灰阶补偿值相加，得到各个补偿显示数据；
步骤S34，将各个补偿显示数据进行格式转换，得到各个补偿驱动数据；
步骤S35，根据各个补偿驱动数据驱动各个TFT产生驱动电流。
首先，获取面板上各个TFT的显示数据，然后将获取到的显示数据与预设显示数据对比，预设显示数据都有与之对应的一个显示灰阶；当确定获取到的显示数据与哪个预设显示数据对应，就能确定当前的显示数据对应的显示灰阶；为了方便理解，可以参照步骤S22中的例子，当确定了当前的显示灰阶后，就能获取到具体的各个TFT对应的各个灰阶补偿值；将各个TFT对应的显示数据与对应的灰阶补偿值相加，得到各个TFT的各个补偿显示数据；最后将各个TFT的各个补偿显示数据进行格式转换得到各个补偿驱动数据，各个补偿驱动数据驱动各个TFT产生驱动电流，使得AMOLED显示面板上的各个像素点发光。
在本实施例中，通过获取各个TFT在不同第一持续上电时长在预设时间区段表中的时间区段，然后在预设灰阶补偿值集中动态提取对应的各个TFT的各个灰阶补偿值；接着根据各个TFT显示数据确定当前的显示灰阶，并根据当前的显示灰阶进一步确定具体的各个TFT的各个灰阶补偿值；最后将各个TFT的各个灰阶补偿值与对应的显示数据相加，得到各个TFT的各个补偿显示数据；再将各个TFT的各个补偿显示数据进行格式转换得到各个补偿驱动数据，各个补偿驱动数据驱动各个TFT产生驱动电流，通过不同的第一持续上电时长和不同的灰阶确定不同的灰阶补偿值，针对不同的TFT、分别在不同的持续上电时长和不同灰阶下产生不同程度温漂，获取不同的补偿值进行补偿，使得各个TFT产生驱动电流更好的保持稳定不变，进而使得更好地解决了AMOLED显示显示残影的问题。
在本申请AMOLED显示残影消除方法第三实施例中，基于上述图2所示的实施例，步骤S20的之前还包括：
步骤S40，在检测到所述显示面板测试上电时，获取所述显示面板中的各个TFT在不同预设灰阶下的第一驱动电流值；
在检测到显示面板测试上电时，在不同预设灰阶下的各个TFT的预设参考亮度值，和不同预设灰阶下的各个TFT的实际亮度值；然后调整在不同预设灰阶下的各个TFT的第一驱动数据，直至使得各个TFT的实际亮度值与预设参考亮度值相等；获取在不同预设灰阶下的各个TFT在实际亮度值与预设参考亮度值相等时的实际驱动电流值，作为第一驱动电流值。
其中，这里显示面板测试上电与步骤S10中显示面板上电不同，这里显示面板测试上电是指AMOLED显示面板还没具备消除显示残功能时，为了计算出各个灰阶补偿值而对显示面板进行上电测试计算；AMOLED显示面板上有多个像素点，每个像素点处都有一个TFT，通过TFT上的控制信号可以控制TFT驱动电流的通断，进而控制像素点发光；实际驱动电流值是指，上电后流过TFT的实际电流，可以通过检测得到；不同灰阶时，同一个TFT对应的实际驱动电流值不同，相同灰阶下，不同的TFT因个体的差异，可能各个TFT对应的实际驱动电流值也不同；所以，不同灰阶时，同一个TFT对应的实际亮度值不同，相同灰阶下，不同的TFT因个体的差异，可能各个TFT对应的实际亮度值也不同；例如，一个设有高、中、低三个灰阶、有M乘以N个像素点的AMOLED显示面板，一个灰阶就有M乘以N个预设参考亮度值，三个灰阶就有M乘以N再乘以3个预设参考亮度值；对应地，一个灰阶可以获取到M乘以N个实际亮度值，就可以得到M乘以N再乘以3个实际亮度值，进而就可以得到M乘以N再乘以3个第一驱动电流值。
步骤S50，根据所述第一驱动电流值，得到各个TFT在不同预设灰阶下的各个灰阶补偿值并存储。
获取在不同预设灰阶下的各个TFT当前的第二驱动电流值，以及对应的第二驱动数据；然后调整各个TFT的第二驱动数据，使得第一驱动电流值和第二驱动电流值，得到各个调整后驱动数据；最后利用各个调整后驱动数据减去各个第二驱动数据，得到各个TFT在不同预设灰阶下的各个灰阶补偿值并存储。
为方便理解，举例进行说明，例如，一个设有高、中、低三个灰阶、有M乘以N个像素点的AMOLED显示面板，一个灰阶就有M乘以N个第一驱动电流值，三个灰阶就有M乘以N再乘以3个第一驱动电流值；对应地，一个灰阶可以获取到M乘以N个第二驱动电流值，三个灰阶一共就可以得到M乘以N再乘以3个第二驱动电流值；对应地，一个灰阶就有M乘以N个第二驱动数据，三个灰阶就有M乘以N再乘以3个第二驱动数据；进而通过调整就可以得到M乘以N再乘以3个灰阶补偿值。
本实施例中，在AMOLED显示产品提供给用户正常使用前，首先预设多个不同的灰阶，即多个不同的预设亮度；然后通过测试检测出刚上电时，各个TFT在不同灰阶下的第一驱动电流值，根据第一驱动电流值进一步确定各个TFT在不同灰阶下的各个灰阶补偿值；各个TFT在相同的灰阶下，因个体的差异，流过各个TFT的第一驱动电流值可能会存在差异，在不同的灰阶下，相同的TFT的第一驱动电流值也各不相同；通过检测各个TFT在不同灰阶下的第一驱动电流值，进一步确定各个TFT在不同灰阶下的各个灰阶补偿值，得到的各个灰阶补偿值更加符合实际；避免各个TFT自身存在差异，统一采用单一一个TFT的驱动电流值来确定各个灰阶补偿值，会存在个体的误差。
进一步地，参照图4，步骤S40包括：
步骤S41，获取所述显示面板在不同预设灰阶下的各个TFT的预设参考亮度值；
首先生成的各个标准灰阶信号，然后根据各个标准灰阶信号依次获取各个灰阶，以及与各个灰阶对应的各个预设参考亮度值，每一个灰阶对应一个预设参考亮度值；同一个灰阶的每个TFT的预设参考亮度值都相同。
步骤S42，获取不同预设灰阶下的各个TFT的实际亮度值；
获取AMOLED显示面板上各个像素点的TFT实际亮度值，每一个灰阶对应一个实际亮度值；理论上，同一个灰阶的每个TFT的实际亮度值都相同。
步骤S43，调整，直至各个TFT的实际亮度值与预设参考亮度值相等；
如图5所示，一个AMOLED显示面板上有M乘以N个像素点，每个像素点对应一个TFT；首先，根据标准灰阶信号将灰阶解码为具有M乘以N个像素点的显示数据，然后将M乘以N个显示数据进行格式转换成M乘以N个驱动数据；然后比较各个TFT的预设参考亮度值与对应的实际亮度值的大小关系，调整驱动数据的大小，使得各个TFT的实际亮度值等于对应的预设参考亮度值；同理地，如果有多个不同的灰阶，比如，有高、中、低三个灰阶，就可以按照前面的这个方法进行调整，使得各个TFT的实际亮度值等于对应的预设参考亮度值。
步骤S44，获取在不同预设灰阶下的各个TFT在实际亮度值与预设参考亮度值相等时的实际驱动电流值，以作为第一驱动电流值。
各个TFT的实际亮度值等于对应的预设参考亮度值后，获取此时的各个TFT的实际驱动电流值，利用获取到的各个TFT的各个实际驱动电流值作为对应像素点的第一驱动电流值，即，获取到的各个TFT的各个实际驱动电流值作为各个TFT的第一驱动电流值；为方便理解，可以参照步骤S43中的图5，一个AMOLED显示面板上有M乘以N个像素点，就有M乘以N个第一驱动电流值；同理地，如果有多个不同的灰阶，比如，有高、中、低三个灰阶，就可以按照前面的这个方法分别获取得到不同灰阶下，各个TFT的第一驱动电流值。
在本实施例中，首先通过预设多个不同的预设参考亮度值作为不同预设灰阶的参考亮度值，各个TFT在相同的灰阶下采用的预设参考亮度值相同；然后获取刚测试上电时，在不同预设灰阶下各个TFT的实际亮度值，并调整在不同预设灰阶下的各个TFT的第一驱动数据，使得各个TFT的实际亮度值与预设参考亮度值相等，获取各个TFT在实际亮度值与预设参考亮度值相等时的实际驱动电流值作为第一驱动电流值；通过分别检测各个TFT的实际亮度值来确定各个TFT的第一驱动电流值，避免了各个TFT自身存在差异，获取一个TFT的实际亮度来确定多个TFT的第一驱动电流值，而导致第一驱动电流值不完全符合各个TFT。
进一步地，步骤S50包括：
步骤S51，获取在不同预设灰阶下的各个TFT当前的第二驱动电流值，以及对应的第二驱动数据；
获取显示面板在测试上电时的第二持续上电时长；分别在不同的第二持续上电时长时间点，获取不同的预设灰阶下的各个TFT的第二驱动电流值，以及对应的驱动数据，直至第二持续上电时长到达阈值时长；
为了方便理解，举例进行说明，例如，在0-15分钟内分别获取三个时间点，第二持续上电时长在5分钟这个时间点、6-10分钟这个时间点、11-15分钟这个时间点；在每个时间点分别获取高、中、低三个不同灰阶的各个TFT的第二驱动电流值，以及各个TFT的第二驱动电流值分别对应的驱动数据。
步骤S52，根据所述第一驱动电流值和第二驱动电流值，调整各个TFT的第二驱动数据得到各个调整后驱动数据；
将获取到第二驱动电流值与第一驱动电流值进行比较，然后根据第一驱动电流值和第二驱动电流值的大小关系调整各个驱动数据；当第一驱动电流值和第二驱动电流值不相等时，调整各个驱动数据的大小，直至所有的第一驱动电流值和对应第二驱动电流值相同；获取各个第一驱动电流值和对应第二驱动电流值相同时的各个实际驱动数据，以作为各个TFT的各个调整后驱动数据。
步骤S53，根据各个调整后驱动数据减去各个第二驱动数据的差值，得到各个TFT在不同预设灰阶下的各个灰阶补偿值并存储。
利用各个调整后驱动数据减去各个第二驱动数据得到的差值作为各个TFT的各个灰阶补偿值；同理，可以得到不同灰阶下各个TFT的各个灰阶补偿值，以及在不同灰阶下、不同的第二持续上电时长的各个TFT的各个灰阶补偿值，将得到的所有灰阶补偿值存储起来。
在本实施例中，通过预设参考亮度值来确定不同灰阶下各个TFT的第一驱动电流值作为标准的参考电流，然后在每个灰阶获取在不同的第二上电时长的各个TFT的第二驱动电流值，利用第二驱动电流值与第一驱动电流值作对比，并调整驱动数据达到改变第二驱动电流值，从而使得第二驱动电流值与第一驱动电流值相等，进而达到流过各个TFT的驱动电流保持不变，保持显示亮度不变，达到消除显示残影的效果。
参照图6，在本申请AMOLED显示残影消除方法第四实施例中，基于上述图5所示的实施例，步骤S51包括：
步骤A1，获取所述显示面板在测试上电时的第二持续上电时长；
步骤A2，分别在不同的第二持续上电时长，获取不同的预设灰阶下的各个TFT的第二驱动电流值，以及对应的驱动数据，直至第二持续上电时长到达阈值时长。
首先设定一个阈值时长，获取显示面板在测试上电时的第二持续上电时长作为一个判断时间点；分别在不同的第二持续上电时长的判断时间点，获取各个TFT的第二驱动电流值，以及各个TFT对应的驱动数据，直至第二持续上电时长到达阈值时长；同理，获取不同的预设灰阶下的各个TFT的第二驱动电流值，以及各个TFT对应的驱动数据。
为了方便理解，举例进行说明，例如，首先设定一个阈值时长，如15分钟，然后将15分钟设定三个时间点5分时、10分时、15分时，分别作为第二持续上电时长的判断时间点，分别获取第二持续上电时长在三个时间点的各个TFT的第二驱动电流值，以及各个TFT对应的驱动数据，直至获取的第二持续上电时长在15分这个时间点；同理地，可以分别获取到在不同的预设灰阶下，各个第二持续上电时长所在的各个时间点的各个TFT的第二驱动电流值，以及各个TFT对应的驱动数据；更具体地，一个设有高、低两个灰阶、有M乘以N个像素点的AMOLED显示面板，一个灰阶就有M乘以N个第一驱动电流值，两个灰阶就有M乘以N再乘以2个第一驱动电流值；对应地，一个灰阶可以获取到M乘以N个第二驱动电流值，两个灰阶一共就可以得到M乘以N再乘以2个第二驱动电流值；对应地，一个灰阶就有M乘以N个驱动数据，两个灰阶就有M乘以N再乘以2个驱动数据；一个设有高、低两个灰阶、有M乘以N个像素点的AMOLED显示面板，在三个判断时间点里，一共就有M乘以N乘以2个第一驱动电流值、M乘以N乘以2再乘以3个第二驱动电流值、M乘以N乘以2再乘以3个驱动数据。
在本实施例中，通过在显示面板测试上电时，获取不同的第二持续上电时长，并获取在不同的第二持续上电时长的各个TFT的第二驱动电流值、以及各个TFT的驱动数据，以便进一步可以得出不同时长下的各个TFT的灰阶补偿值；避免了在不同持续上电时长产生的温漂大小不同，只有单一的灰阶补偿值无法准确补偿一定时长后TFT的温漂；使得用户在正常使用时，在不同的上电时长可以通过不同的灰阶补偿值进行补偿，进而可以在较长的一段连续时间内较好地消除显示残影问题。
进一步地，步骤S52包括：
步骤B1，根据所述第一驱动电流值和第二驱动电流值的大小关系，调整各个驱动数据的大小，直至所述各个第一驱动电流值和第二驱动电流值相同；
步骤B2，获取各个在第一驱动电流值和第二驱动电流值相同时的实际驱动数据，以作为各个调整后驱动数据。
根据各个第一驱动电流值与对应各个第二驱动电流值的大小关系，调整对应各个驱动数据的大小；当第一驱动电流值大于对应第二驱动电流值时，调小驱动数据；当第一驱动电流值小于对应第二驱动电流值时，调大驱动数据；当第一驱动电流值等于对应第二驱动电流值时，维持驱动数据不变；直至所有的第一实际驱动电流值与对应的各个第二驱动电流值相同；获取第一实际驱动电流值与对应的各个第二驱动电流值相同时各个TFT实际驱动数据，将获取到的各个TFT实际驱动数作为各个调整后驱动数据。
为了方便理解，进行举例说明，例如，一个设有高、中、低三个灰阶、有M乘以N个像素点的AMOLED显示面板，一个灰阶就有M乘以N个第一驱动电流值，三个灰阶就有M乘以N再乘以3个第一驱动电流值；对应地，一个灰阶可以获取到M乘以N个第二驱动电流值，三个灰阶一共就可以得到M乘以N再乘以3个第二驱动电流值；对应地，一个灰阶就有M乘以N个驱动数据，三个灰阶就有M乘以N再乘以3个驱动数据；通过调整M乘以N再乘以3个驱动数据，就可以获取得到M乘以N再乘以3个在第一驱动电流值和第二驱动电流值相同时的实际驱动数据，即可以获取得到M乘以N再乘以3个调整后驱动数据。
在本实施例中，通过不同的第二持续上电时长和不同的灰阶来调整驱动数据，使第二驱动电流与第一驱动电流保持一致，从而确定不同的灰阶补偿值，使得用户在使用时AMOLED显示时，在不同的持续上电时间，有对应的灰阶补偿值进行补偿，避免了在不同持续上电时长产生的温漂大小不同，只有单一的灰阶补偿值无法准确补偿一定时长后TFT的温漂，获取了不同的第二持续上电时长和不同的灰阶下的灰阶补偿值。
