具体实施方式
为使本公开的目的、技术方案和优点更加清楚明白，以下结合具体实施例，并参照附图，对本公开进一步详细说明。
本公开实施例提供了一种WOLED显示装置的补色方法，用于改进补色方法。WOLED显示装置的补色方法通常包括：通过测量某一亮度下的R、G、B、W子像素色坐标(R、G、B、W子像素色坐标代表的含义是：R子像素色坐标、G子像素色坐标、B子像素色坐标和W子像素色坐标，即四个子像素各自的色坐标；显然，本文中后述的相同或相似表述形式均代表上述含义)，通过色度学混色公式计算得到R、G、B、W子像素补色比例；再确定W输出亮度(W子像素的输出亮度)，然后用W输出亮度乘以R、G、B、W子像素补色比例，获得R、G、B、W子像素补色亮度，实现WOLED显示装置的补色。上述的补色方法存在补色不准确的问题，影响显示效果。
参考图1，为本公开实施例的WOLED显示装置的补色方法流程图。
所述WOLED显示装置(例如，WOLED显示面板)的补色方法，包括以下步骤：
步骤101、确定至少两个目标输出亮度。
本步骤中，所述目标输出亮度为WOLED显示装置在实际工作中能够达到输出亮度。在后续的步骤中，为了能够通过目标输出亮度 对应的待用数据来计算生成WOLED显示装置的输出亮度与R、G、B、W子像素补色亮度的关联关系，则目标输出亮度的个数至少二两个。
作为可选的，在选取目标输出亮度时，以预设亮度间隔连续获得至少两个亮度值作为目标输出亮度。采用相同间隔的至少两个目标输出亮度能够方便的进行数据选取，且在后续的计算处理时能够提高准确度。显然，选取的预设亮度间隔越小，后续的计算处理得到的关联关系越准确，但是其对应的数据设定和计算的处理工作量确越大。所以，基于数据设定和计算的处理工作量的考虑，在可选的实施例中，所述预设亮度间隔的设置区间为1-20尼特；其中，预设亮度间隔的可选的取值为10尼特；而总共确定的目标输出亮度的个数为40个。在上述可选的预设亮度间隔和目标输出亮度个数的设置下，数据处理量适中，能够方便、高效的进行后续步骤的实测过程，且计算处理的结果的准确度较高。
显然，在其他实施例中，在确定目标输出亮度时，根据实际的实施需要，也可以采用不等亮度间隔的方式来确定至少两个目标输出亮度。
步骤102、分别使用至少两个所述目标输出亮度对所述WOLED显示装置进行实测调节，获得待用数据。
本步骤中，所述的实测调节具体包括：使所述WOLED显示装置的输出亮度等于目标输出亮度，调节R、G、B、W子像素输出亮度，使所述WOLED显示装置的输出色坐标达到预设色坐标并记录此时的R、G、B、W子像素输出亮度为R、G、B、W子像素补色亮度。其中，所述的预设色坐标为预先设定的所述WOLED显示装置实际应该达到的输出色坐标(在理想状态下，该预设色坐标不会随WOLED显示装置的输出亮度的改变而变化)。对于每个确定的所述目标输出亮度均进行上述的实测调节过程，记录下每个目标输出亮度对应的R、G、B、W子像素补色亮度。
相对应的，所述待用数据即包括：至少两个所述目标输出亮度及其分别对应的所述R、G、B、W子像素补色亮度。
步骤103、根据所述待用数据，生成所述WOLED显示装置的输出亮度与R、G、B、W子像素补色亮度的关联关系。
由于前述步骤得到的待用数据的至少两组成对数据(目标输出亮度与R、G、B、W子像素补色亮度的对应)，则可以通过数值处理的方法，基于不连续的至少两组成对数据，获得该成对数据对应的两个量之间的连续的关联关系。而在本步骤中，则是基于待用数据，通过插值法或拟合法对待用数据进行计算处理，得到WOLED显示装置的输出亮度(对应于待用数据中的目标输出亮度)与R、G、B、W子像素补色亮度的关联关系。
步骤104、根据所述关联关系，对所述WOLED显示装置进行补色(即进行显示控制)。例如，根据所述关联关系获得对所述WOLED显示装置进行补色的补色数据，利用所述补色数据对所述WOLED显示装置进行补色。
本步骤中，将前述步骤得到的所述关联关系应用于WOLED显示装置的实际显示过程，即基于所述关联关系，对所述WOLED显示装置进行补色。具体的，根据所述关联关系进行补色的过程包括：确定所述显示装置的输出亮度；根据所述关联关系，确定所述显示装置的输出来亮度对应的R、G、B、W子像素补色亮度；将R、G、B、W子像素输出亮度调节为所述R、G、B、W子像素补色亮度。
由于所述关联关系是基于所述WOLED显示装置的待用数据计算而来，所以该关联关系与所述WOLED显示装置也存在着一对一的对应关系。也就是说，对于每一个WOLED显示装置而言，本公开实施例均提供了其专属的补色方法。使用本公开实施例的补色方法对WOLED显示装置进行补色，显然能够最大程度的提升补色准确度，有效的改善WOLED显示装置的实际显示效果。
在一些可选的实施例中，所述WOLED显示装置的补色方法还包括：初始补色步骤。参考图2，为本公开实施例中的初始补色步骤的流程图。
在本实施例中，首先执行所述初始补色步骤，即所述初始补色步骤应在前述实施例中的步骤101之前执行。
所述初始补色步骤，包括以下步骤：
步骤201、获取所述WOLED显示装置某一输出亮度下的R、G、B、W子像素计算色坐标。
本步骤中，将所述WOLED显示装置加电进行正常显示过程，将WOLED显示装置调节至某一输出亮度(该输出亮度由本领域技术人员根据经验而设定)，然后记录此时R、G、B、W子像素输出亮度，作为R、G、B、W子像素计算色坐标。
作为可选的，在获得R、G、B、W子像素计算色坐标时，采用如下实施方式：将WOLED显示装置加电进行正常显示过程，然后持续增大WOLED显示装置的输出亮度。在上述过程中，对应于WOLED显示装置的输出亮度的增大，R、G、B、W子像素色坐标会随之明显改变。由于WOLED显示装置的制作工艺原因，当WOLED显示装置的输出亮度增大到某一值时，R、G、B、W的色坐标将不再随着WOLED显示装置的输出亮度的增大而改变(或是明显改变)，此时R、G、B、W子像素色坐标较为接近实际工作时显示的色坐标，所以记录此时的R、G、B、W子像素色坐标为R、G、B、W子像素计算色坐标，这能够提升本实施例中由初始补色步骤获得的补色比例的准确性。
步骤202、基于所述R、G、B、W子像素计算色坐标，计算得到R、G、B、W子像素初始补色比例。
本步骤中，基于前述步骤中获得的R、G、B、W子像素计算色坐标，通过色度学混色公式进行计算，得到R、G、B、W子像素初始补色比例。本步骤计算得出R、G、B、W子像素初始补色比例的过程为现有技术，其具体的计算过程和原理公式不再详述。
步骤203、根据所述R、G、B、W子像素初始补色比例，对所述WOLED显示装置进行补色。
本步骤中，将前述步骤得到的R、G、B、W子像素初始补色比例应用至所述WOLED显示装置的实际显示过程。具体的，使用所述R、G、B、W子像素初始补色比例进行补色的过程包括：确定所述显示装置的W输出亮度，使所述显示装置的W输出亮度乘以所述R、 G、B、W子像素初始补色比例，获得R、G、B、W子像素初始补色亮度，将R、G、B、W子像素输出亮度调节为所述R、G、B、W子像素初始补色亮度。
在本实施例中，首先执行所述的初始补色步骤，即通过前述的补色方法，先确定一个R、G、B、W子像素补色比例并应用到WOLED显示装置上。这样，在执行后续的步骤101至步骤104时，是在一个较为准确(“较为准确”是相比于没有补色机制的WOLED显示装置)的补色比例基础上进行的，这使得在后续步骤中，确定的所述目标输出亮度的数量可以选择相对较少，后续计算过程的数据处理量也会相应减少，这能够明显提高本申请的补色方法的执行效率。
基于同一公开构思，本公开实施例还提供了一种应用上述任意实施例的WOLED显示装置的补色方法的显示装置。该显示装置包括：补色模块，用于根据所述关联关系，对所述WOLED显示装置进行补色。根据本公开的一个实施例，补色模块可以由相应的补色电路来构造，例如，可以利用相应地配置的硬件电路来实现该补色模块，在下文中将对补色模块进行更详细地说明。
在具体实施中，所述补色模块可以为WOLED显示装置中的TCON(屏驱动板)的组件，也可以是单独设置的功能模块。相应地，本公开的一些实施例可以提供一种具有上述补色模块的显示装置，而另一些实施例可以提供一种用于对显示装置进行补色的补色装置，所述补色装置可以与显示装置的驱动器进行通信以将补色信号输出给显示装置的驱动器。此外，WOLED显示装置还包括：Color Engine(色度处理器):对R、G、B、W子像素的亮度与色坐标进行运算，执行前述方法实施例中的初始补色步骤，将结果信息(R、G、B、W子像素初始补色比例)输出给PG Controller与TCON Controller。PG Controller(灰度控制模块)：依照Color engine提供的结果信息，输出R、G、B的灰阶数值。TCON Controller(屏驱动板控制模块)：依照Color engine提供的结果信息，决定RGB to RGBW的显示方式。
当所述补色模块作为TCON的组件时，所述关联关系存储于TCON的Memory(存储单元)中，TCON读取Memory中的关联关 系，获得当前显示装置的输出来亮度对应的R、G、B、W子像素补色亮度，然后与PG Controller和TCON Controller配合工作，进行补色显示工作。当所述补色模块作为单独模块工作时，所述补色模块具有存储器来储存所述关联关系，TCON读取所述补色模块中的关联关系，获得当前显示装置的输出来亮度对应的R、G、B、W子像素补色亮度，然后与PG Controller和TCON Controller配合工作，进行补色显示工作。另外，当所述补色模块作为单独模块工作时，所述补色模块可以具有处理器以及代码存储器，当代码存储器中存储的计算机可读代码在所述处理器中执行时，使得所述处理器执行前述实施例的WOLED显示装置的补色方法。
显然，由于应用了前述实施例的WOLED显示装置的补色方法，所述显示装置具有补色准确度高、显示效果好的技术效果。
所属领域的普通技术人员应当理解：以上任何实施例的讨论仅为示例性的，并非旨在暗示本公开的范围(包括权利要求)被限于这些例子；在本公开的思路下，以上实施例或者不同实施例中的技术特征之间也可以进行组合，步骤可以以任意顺序实现，并存在如上所述的本公开的不同方面的许多其它变化，为了简明它们没有在细节中提供。
另外，为简化说明和讨论，并且为了不会使本公开难以理解，在所提供的附图中可以示出或可以不示出与集成电路(IC)芯片和其它部件的公知的电源/接地连接。此外，可以以框图的形式示出装置，以便避免使本公开难以理解，并且这也考虑了以下事实，即关于这些框图装置的实施方式的细节是高度取决于将要实施本公开的平台的(即，这些细节应当完全处于本领域技术人员的理解范围内)。在阐述了具体细节(例如，电路)以描述本公开的示例性实施例的情况下，对本领域技术人员来说显而易见的是，可以在没有这些具体细节的情况下或者这些具体细节有变化的情况下实施本公开。因此，这些描述应被认为是说明性的而不是限制性的。
尽管已经结合了本公开的具体实施例对本公开进行了描述，但是根据前面的描述，这些实施例的很多替换、修改和变型对本领域普 通技术人员来说将是显而易见的。例如，其它存储器架构(例如，动态RAM(DRAM))可以使用所讨论的实施例。
从上面所述可以看出，本公开提供的WOLED显示装置的补色方法、WOLED显示装置，通过对WOLED显示装置进行实际使用测试，分别在不同的输出量度下将当前输出色坐标调节至预设色坐标，并记录下至少两组待用数据，并基于待用数据获得完整的补色亮度与输出亮度的关联关系后对WOLED显示装置进行补色，提升补色准确度，改善显示效果。
本公开的实施例旨在涵盖落入所附权利要求的宽泛范围之内的所有这样的替换、修改和变型。因此，凡在本公开的精神和原则之内，所做的任何省略、修改、等同替换、改进等，均应包含在本公开的保护范围之内。
