技术领域
本公开涉及显示技术，特别是一种显示处理方法、装置及显示器件。
背景技术
各种类型的平面显示器的制造都涉及到多个流程，如液晶平面显示器中液晶面板的制造涉及背光模组、偏光膜、增亮膜、玻璃基板压合等复杂流程与材料，若其中某一道制造出现小瑕疵，可能会使得最后的点亮测试时出现显示不均匀区域(表现为亮点、暗点、亮区与暗区等)。
显示不均匀区域的形状方面各式各样，如横向条纹、四十五度角条纹、方块或者其他无规则的形状。
显示不均匀区域会影响用户的视觉感知，减少显示不均匀区域的发生可以通过材料、工艺、配方、制造程序等的改善来实现，然而上述的方案都会使得制造流程复杂化。
基于上述的考虑，相关技术中还有一种通过信号处理的方式来改善显示不均匀现象的技术方案，包括如下步骤：
拍摄稳定状态下的显示面板的图像；
分析该图像确定显示不均匀区域中每一个亚像素的位置特征、不均匀类型特征以及亮度差异特征等，进而根据上述确定的数据来计算每一个亚像素的数据驱动信号补偿值；
根据上述的数据驱动信号补偿值形成记录显示不均匀区域中每一个亚像素的数据驱动信号补偿值的补偿表。
在显示过程中，针对显示不均匀区域中每一个亚像素，以及该补偿表中记 录的显示不均匀区域中每一个亚像素的数据驱动信号补偿值，对亚像素对应的原始数据驱动信号进行补偿。
然而，上述的技术方案存在对显示不均匀的补偿效果较差的问题，说明如下。
上述的通过信号处理方式来改善显示不均匀现象的技术方案中，在显示过程中的任意时间点都是依据固定的补偿值进行补偿，因此对显示不均匀现象的改善有限。

具体实施方式
下面将结合本公开实施例中的附图，对实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例是本公开的一部分实施例，而不是全部实施例。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的前提下所获得的所有其他实施例，都应属于本公开保护的范围。
本公开实施例的显示处理方法、装置及显示处理方法、装置及显示器件中，根据显示不均匀现象的时变特性，在不同时间点依据当前时间点的显示不均匀程度进行不同的补偿，改善了显示不均匀现象。
本公开实施例的一种显示处理方法，用于一显示器件，所述显示器件的显示区域包括显示不均匀区域，如图1所示，所述显示处理方法包括：
时间获取步骤101，获取所述显示器件本次启动后的已工作时间；
数据转换步骤102，根据所述已工作时间确定位于显示不均匀区域的待补偿亚像素对应的目标显示数据。
在此应该说明的是，本公开具体实施例中，所述显示不均匀区域可能是显示区域的一部分，也可能是显示区域的全部，即本公开实施例中并不限定显示不均匀区域的大小。
本公开实施例中，在显示器件启动之后即开始记录本次启动后的已工作时间，而在显示过程中，会根据已工作时间对待发送到显示不均匀区域中的原始显示数据进行转换，得到能够补偿与当前的已工作时间相对应的显示不均匀的目标显示数据。与现有技术相比，本公开实施例的方法考虑了显示不均匀现象的时变特性，对显示不均匀现象具有更好的补偿效果。
在此应当理解的是，上述的已工作时间指的是显示器件本次的累计工作时间，一旦显示器件开始停止工作(如断开电源、或进入睡眠状态等停止向显示面板发送驱动数据)，则已工作时间归零。
应当理解的是，本公开实施例中的显示器件可以为各种类型的平面显示器件，如液晶显示器、激发光二极管显示器、等离子显示器等。
在本公开具体实施例中，对于数据转换，示例性地描述了两种方式来实现，一种方式为实时运算方式，而另一种方式为映射方式，下面分别详细说明如下。
<实时运算方式>
如图2所示，本公开实施例的另一显示处理方法包括：
时间获取步骤101，获取所述显示器件本次启动后的已工作时间；
方向确定步骤1021，依据所述待补偿亚像素的不均匀类型确定补偿方向；
系数确定步骤1022，依据所述已工作时间确定所述待补偿亚像素的补偿系数；
计算步骤1023，根据所述补偿系数和预先确定的所述待补偿亚像素对应的补偿基准值确定一补偿量；所述待补偿亚像素对应的补偿基准值为所述待补偿亚像素的显示不均匀现象达到稳定状态时消除所述待补偿亚像素的显示不均匀现象所需要的补偿值。
数据补偿步骤1024，在所述补偿方向上利用所述补偿量对所述待补偿亚像素的原始显示数据进行补偿，得到所述待补偿亚像素对应的目标显示数据。
可选地，如图3所示，在计算步骤1033(即图2计算步骤1023的一个例子)中，可以计算补偿系数和预先确定的所述待补偿亚像素对应的补偿基准值的乘积，得到补偿量。此处不再重复描述采用与图2相同标记的步骤。应理解，本公开还可以通过补偿系数和补偿基准值的其它关系式获得补偿量。
对此进一步详细说明如下。
本公开具体实施例中，在点亮测试显示面板时，即可找出该显示面板的显示不均匀区域的如下信息：位置信息、类别信息以及补偿基准值，其中：
一般而言，显示面板的最小显示单位为亚像素，在本公开具体实施例中，将位于显示不均匀区域内的亚像素称为显示不均匀亚像素，而将位置位于正常区域内的亚像素称为正常亚像素。只有知道不均匀亚像素的位置才能对其进行补偿，所以本公开实施例中，需要预先获得不均匀亚像素的位置信息。
各种类型的平面显示器的制造都涉及到多个流程，如液晶平面显示器中液晶面板的制造涉及背光模组、偏光膜、增亮膜、玻璃基板压合等复杂流程与材料，若其中某一道制造出现小瑕疵，可能会使得最后的点亮测试时出现显示不均匀区域，其表现为亮点、暗点、亮区与暗区等。点和区的区别在于，点指的是一个亚像素，而区则包括多个亚像素。由于各类别的显示不均匀区域所需的补偿方式不尽相同，所以需要预先获知亚像素的不均匀类型。
由于各类别的显示不均匀区域所需的补偿不尽相同，如相对较暗的暗点需要补偿的亮度较大，因此针对显示不均匀亚像素还需要预先获知其补偿基准值。
随着驱动电压加载到液晶面板的时间越来越长，由于液晶分子对电信号比较敏感，因此液晶分子显示特性会有较大的变化。当这些变化作用于显示不均匀时表现为：本次启动后，随着工作时间的增加，显示不均匀的现象会越来越弱，最终趋于稳定。换句话说，在刚启动时，显示不均匀现象比较严重，随着 工作时间的增加，显示不均匀现象会减弱，但一段时间之后，显示不均匀现象不再变化，维持在一定程度。
在现有技术中，数据驱动信号补偿值与时间无关，因此，当适用于稳定阶段的数据驱动信号补偿值在稳定阶段能够较好的消除显示不均匀现象时，而在显示不均匀现象稳定之前，由于不均匀程度较高，适用于稳定阶段的数据驱动信号补偿值无法完全消除显示不均匀现象。
与现有技术不同的是，本公开具体实施例，在显示器件工作过程中，不再是以固定不变的补偿基准值进行补偿，而是根据本次启动后的已工作时间来确定合适的补偿系数，对补偿基准值进行调整，得到与当前的显示不均匀像素的不均匀程度相匹配的补偿量，最后利用调整后的补偿量进行补偿处理。
因此，在本公开实施例中，对显示不均匀像素的不均匀补偿是与显示不均匀像素当前的不均匀程度相匹配的，对显示不均匀现象具有更好的补偿效果。
之前已经提到，随着已工作时间的延长显示不均匀的程度逐步降低，因此在本公开具体实施例中，当显示不均匀的程度变低，即已工作时间越长时，可以相应地减小所述补偿系数。可选地，补偿系数可以是时间的函数，如阶梯函数或者连续函数等方式来实现。下面示例性地描述了两种实现补偿系数的方式。
其中一种方式下，建立补偿系数的随时间t变化的时变减函数f(t)，随时利用该时变减函数计算与已工作时间对应的补偿系数。换句话说，f(t)是一个减函数。例如，补偿系数随已工作时间的增大而减小。
另一种方式下，将所述已工作时间的取值范围分为连续的至少两个时间区间，在后的时间区间对应的补偿系数小于在先的时间区间对应的补偿系数，所述系数确定步骤具体包括：
判断所述已工作时间所在的目标时间区间，其中目标时间区间为至少两个时间区间之一；
根据预先存储的所述时间区间与补偿系数的对应关系，确定所述目标时间区间对应的补偿系数作为所述待补偿亚像素的补偿系数。
其中，在该至少两个时间区间中的在后的时间区间的取值大于在先的时间区间的取值。
举例说明如下。
假定显示不均匀现象趋于稳定需要15分钟，则可以将已工作时间的取值分为如下4个时间区间，如：
时间区间1：启动-5分钟；
时间区间2：5分钟-10分钟；
时间区间3：10分钟-15分钟；
时间区间4：启动15分钟以后。
而每一个时间区间与补偿系数的对应关系如下表所示。
时间区间 补偿系数
时间区间1：启动-5分钟 A1
时间区间2：5分钟-10分钟 A2
时间区间3：10分钟-15分钟 A3
时间区间4：启动15分钟以后 A4
则上述的补偿系数应该满足如下的关系：A1＞A2＞A3＞A4＝1。
如A1＝2.5，A2＝2.0，A3＝1.5，A4＝1。
当然，以上的时间分区和A1、A2、A3和A4的取值仅仅是举例说明。如需要更好的改善显示不均匀现象，则分区可以设置多一些，而要求降低系统的实现复杂度时，则分区可以设置少一些。
而上述具体的与时间区间相对应的补偿系数可以根据实验得到，在此不作详细描述。
可以发现，最后一个时间区间的起点为显示不均匀画面达到稳定时的时间点，且所述最后一个时间区间对应的补偿系数为1。
上述的实时计算的方式中，只需要预先存储两组数据：补偿系数以及亚像素对应的补偿基准值，因此需要的存储空间较小。
<映射方式>
在本公开的具体实施例中，实时计算每一个亚像素对应的补偿量，对每一个亚像素执行如下处理：根据已工作时间查找补偿系数、查找亚像素对应的补偿基准值、计算补偿系数和补偿基准值的乘积得到补偿量、根据补偿量对原始显示数据进行转换。
当显示不均匀区域的亚像素较多时，为了减少数据计算量，提高实时性， 本公开实施例的另一显示处理方法如图4所示，包括：
时间获取步骤101，获取所述显示器件本次启动后的已工作时间；
映射步骤1025，根据对应于待补偿亚像素预先保存的如下三者的对应关系：时间、调整前显示数据以及调整后显示数据，选择与已工作时间和当前接收到的显示数据相对应的调整后显示数据，作为所述目标显示数据。
在该实施例中，将图2或图3所示的实施例的计算补偿系数和补偿基准值的乘积得到补偿量以及根据补偿量对原始显示数据进行计算得到目标显示数据预先计算好，并预先保存好待补偿亚像素的时间、调整前显示数据以及调整后显示数据的对应关系。
在工作过程中，可以依据已工作时间和原始显示数据在对应关系中进行一次查找进行确定目标显示数据，这样大大减少了运算量，节约了处理器有限的处理资源。
在本公开具体实施例中，当所述显示器件的显示区域包括由待补偿亚像素形成的显示不均匀区域及正常区域时，对于正常区域，在任何一种方式中可以不需要进行任何的补偿处理，为了保证正常区域的亚像素对应的原始显示数据不会进入到数据转换步骤进行“0补偿操作”(在逻辑器件的实现上，即使最终没有补偿也需要占用一定的处理时间，如将加法器的一个输入口设置为0，此时输入和输出相同，即实现了“0补偿”，但这种处理也需要耗费时间)，带来无谓的处理资源以及时间的消耗。本公开实施例的另一显示处理方法，如图5所示，包括：
时间获取步骤101，获取所述显示器件本次启动后的已工作时间；
亚像素确定步骤103，确定当前接收到的原始显示数据所对应的目标亚像素；
流转控制步骤104，判断所述目标亚像素是否位于所述显示不均匀区域内，获取判断结果，在所述判断结果指示所述目标亚像素位于所述显示不均匀区域内时，进入所述数据转换步骤102，否则进入输出步骤105；
数据转换步骤102，根据所述已工作时间确定与待发送到所述待补偿亚像素的原始显示数据对应的目标显示数据；
输出步骤105，输出所述原始显示数据。
在该实施例中，将位于正常区域内的亚像素对应的原始显示数据直接输出，提高了处理速度。
为了实现上述目的，本公开实施例还公开了一种显示处理装置，用于一显示器件，所述显示器件的显示区域包括显示不均匀区域，如图6所示，所述显示处理装置包括：
时间获取模块，用于获取所述显示器件本次启动后的已工作时间；
数据转换模块，用于根据时间获取模块获取的所述已工作时间确定位于显示不均匀区域的待补偿亚像素对应的目标显示数据。
在此应该说明的是，本公开具体实施例中，所述显示不均匀区域可能是显示区域的一部分，也可能是显示区域的全部。
在该实施例中，在显示器件启动之后即开始记录本次启动后的已工作时间，而在显示过程中，会根据已工作时间对待发送到显示不均匀区域中的原始显示数据进行转换，得到能够补偿与当前的已工作时间相对应的显示不均匀的目标显示数据。与现有技术相比，本公开实施例的方法考虑了显示不均匀现象的时变特性，对显示不均匀现象具有更好的补偿效果。
如图7所示，本公开实施例的另一显示处理装置包括：
时间获取模块，用于获取所述显示器件本次启动后的已工作时间；
亚像素确定模块，用于确定当前接收到的原始显示数据所对应的目标亚像素；
流转控制模块，用于判断所述目标亚像素是否位于所述显示不均匀区域内，获取一判断结果，在所述判断结果指示所述目标亚像素位于所述显示不均匀区域内时，触发所述数据转换模块，否则触发输出模块；
输出模块，用于输出所述原始显示数据。
