通过上述附图，已示出本申请明确的实施例，后文中将有更详细的描 述。这些附图和文字描述并不是为了通过任何方式限制本申请构思的范围，而是通过参考特定实施例为本领域技术人员说明本申请的概念。
具体实施方式
这里将详细地对示例性实施例进行说明，其示例表示在附图中。下面的描述涉及附图时，除非另有表示，不同附图中的相同数字表示相同或相似的要素。以下示例性实施例中所描述的实施方式并不代表与本申请相一致的所有实施方式。相反，它们仅是与如所附权利要求书中所详述的、本申请的一些方面相一致的装置和方法的例子。
随着显示技术的发展和逐渐成熟，在显示面板上安装屏下摄像头，以提高显示面板的显示面积成为可能。
一般来说，为了保证屏下摄像头的正常工作，显示面板上安装有屏下摄像头的显示区域会增加一定的显示透光率，而降低显示发光率，以保证屏下摄像头的正常工作。
图1为一种现有技术中的显示面板的界面示意图，如图1所示的，在现有的显示面板中，为了尽可能地增加显示面积，会在显示面板的部分区域，如图1所示的位于显示面板顶部的第一显示区域，设置屏下摄像头，另外，图1中的第二显示区域为未设置屏下摄像头的区域，其中，在该设置有屏下摄像头的第一显示区域，面板依旧可发光和显示。从而，第一显示区域和第二显示区域都可以用于进行内容显示，增加了显示面板的显示面积。
为了保证屏下摄像头能够正常运转以获得外部图像，在该设置有屏下摄像头的第一显示区域，通常被设置为呈现透明状，相应的，该第一显示区域的透光率也大大提升，同时，该第一显示区域的发光率相应降低。然而，上述设置会导致该第一显示区域与第二显示区域的显示亮度呈现不一致的情况，具体为第一显示区域与第二显示区域相比，第一显示区域的显示画面所呈现的亮度较低，视觉效果很差。
面对上述技术情况，如何改善设置有屏下摄像头的显示面板的显示质量成为亟待解决的问题。
本申请的主要构思为：可利用不同的伽马曲线对不同显示区域的显示 电压进行调节，以使不同显示区域的显示亮度保持相对平衡。也就是说，本申请提供的显示方法、显示面板、显示控制装置、存储介质及产品，通过对于待显示数据进行灰阶转换处理，以使得针对于显示面板上不同显示区的待显示数据的灰阶值，采用不同的伽马曲线进行灰阶值的映射，以得到可用于控制显示区显示亮度的显示电压，而采用这样的分区的显示控制方式，能够有效对于保证不同显示区的显示亮度维持在相同或相似的水平，特别针对于安装有屏下摄像头的显示面板，显示质量明显得到提升。
下面以具体实施例对本申请的技术方案以及本申请的技术方案如何解决上述技术问题进行详细说明。下面的这几个具体实施例可以相互结合，对于相同或相似的概念或过程可能在某些实施例中不再赘述。
需要说明的是，本申请实施例所述显示面板可为仅具备显示功能的显示器，也可为可提供操作交互功能的显示面板。此外，该显示面板可为具备折叠、弯折或卷曲功能的柔性面板，也可为不具备折叠、弯折或卷曲功能的传统面板。当然，随着技术的发展，该显示面板还可为各种新形态的面板。
本申请实施例提供的显示方法具体可适用于显示面板，其中，该显示面板上包括有不同的显示区，即第一显示区和第二显示区。
需要说明的是，该第一显示区和第二显示区均为相对区域的概念，其两个显示区在显示面板上的布设位置和具体大小划分均可根据实际情况而定，本申请实施例对此也不进行任何限制。
举例来说，在一种实际的显示面板的布设方式中，第一显示区为设置有屏下摄像头的区域，该第一显示区可以为透明区域；而第二显示区为显示面板上未设置有屏下摄像头的区域，该第二显示区可以为非透明区域；当然，在其他布设方式中，第二显示区为设置有屏下摄像头的区域，而第一显示区为显示面板上未设置有屏下摄像头的区域。
在本申请实施例中，为了便于描述，将以第一显示区为设置有屏下摄像头的区域，所述第二显示区为未设置有屏下摄像头的区域为例进行说明。
图2为本申请实施例提供的一种显示方法的流程示意图，如图2所示的，该显示方法包括：
步骤101、根据待显示数据所属于的显示区，对所述待显示数据进行灰阶转换处理，获得待显示数据的灰阶值；
步骤102、利用不同的伽马曲线分别对第一显示区对应的待显示数据的灰阶值和第二显示区对应的待显示数据的灰阶值进行映射处理，获得第一显示电压和第二显示电压；其中，所述伽马曲线用于表示灰阶值和显示电压之间的对应关系；
步骤103、根据所述第一显示电压和所述第二显示电压，控制所述显示面板的第一显示区和第二显示区进行显示，以使所述第一显示区的显示亮度与所述第二显示区的显示亮度相同或相似。
具体来说，该实施例提供的显示方法的执行主体具体可为显示控制装置，其包括但不限于控制器、控制设备、控制逻辑电路、控制芯片等硬件设备；还可包括基于指令实现的安装于硬件设备上的软件。本申请实施例对其执行主体的具体形态不进行限制。
首先，显示控制装置将获取待显示数据，该待显示数据为显示面板所基于的显示设备的核心处理单元发送给显示面板的，一般来说，该待显示数据包括有显示面板的每个像素对应的数据信息以及发光时序等信息。
而显示控制装置在获得该待显示数据之后，将首先确定待显示数据所属于的显示区，即将第一显示区的待显示数据和第二显示区的待显示数据区分开来以便于后续处理。
随后，显示控制装置将对待显示数据进行灰阶转换处理方法，以获得待显示数据的灰阶值。然后，利用不同的伽马曲线分别对第一显示区对应的待显示数据的灰阶值和第二显示区对应的待显示数据的灰阶值进行映射处理，获得第一显示电压和第二显示电压；其中，所述伽马曲线用于表示灰阶值和显示电压之间的对应关系，所述第一显示电压为第一显示区的显示电压，第二显示电压为第二显示区的显示电压。
其中，灰阶值是一种用于区分显示灰度的属性，通过对其灰阶值的确定和调整，能够使得像素的显示效果得到良好的提升。而为了便于利用灰度值对显示电压进行调整，在本申请实施例中，将利用不同的伽马曲线对于不同显示区的灰阶值和显示电压进行映射，以使得不同显示区采用不同的显示电压进行显示，从而能够根据不同显示区的特性采用不同的显示亮度，进而保证整个显示面板的显示亮度是平衡的，提高显示质量。
下面将结合附图对本申请实施例提供的显示方法的原理和实现方式进行进一步说明：
图3为本申请实施例提供的一种伽马曲线的曲线示意图，如图3所示的，伽马曲线是一种可用于确定灰阶值和亮度(显示电压)之间对应关系的曲线。
一般来说，在显示面板出厂时，每个显示面板均具有自身的出厂伽马曲线，而为了保证显示面板的显示效果，出厂前会利用标准的目标伽马曲线对显示面板的出厂伽马曲线进行一定的曲线的修正，以使修正后的伽马曲线与目标伽马曲线保持尽可能的相似。
其中的目标伽马曲线具体可为显示行业通用的曲线，其一般与灰阶值和最大亮度相关联。在灰阶范围为1-255的情况下，目标伽马曲线可表示为：y＝(n/255) 2.2*Y；
其中，n为灰阶值，y为灰阶值n下的亮度；Y为显示面板的最大亮度。
将n＝1、2……255依次代入该公式，可得到表示灰阶值与亮度(显示电压)之间的对应关系曲线(如图3所示)，该曲线则构成前述的目标伽马曲线。
在实际产品中，显示控制装置中将单独设置一组用于存储伽马曲线的寄存器，在显示面板出厂时，该寄存器中存储有出厂伽马曲线，而利用前述的目标伽马曲线，可对于寄存器中存储的每一曲线的取值进行修正，以使其存储的伽马曲线趋近于目标伽马曲线，以得到前述的预设的伽马曲线。
在本申请中，为了使得不同显示区对应不同的伽马曲线，在其中一种可选的实施方式中，显示方法还包括：
步骤104、对预设的伽马曲线进行分割处理，获得不同显示区对应的伽马曲线。
具体来说，显示控制装置中存储的预设的伽马曲线，还将被进行分割处理，以形成不同显示区对应的伽马曲线。
在图3所示预设的伽马曲线的基础上，显示控制装置将按照预设的伽马曲线的曲线平滑度对曲线进行线段分割处理，获得所述预设的伽马曲线的N个曲线段，其中N为正整数且为偶数，如图3所示的30个曲线段。
进一步的，在线段分割处理时，可基于伽马曲线的绑点。其中，将255灰阶的预设的伽马曲线分成若干曲线段，分割点的位置称为绑点。
绑点位置设定通常参照伽马2.2曲线的平滑度进行设定，其中，对于伽马曲线中较为平滑(即亮度随灰阶值的变化较小)的部分，分割的绑点数量较少，即每个绑点之间间隔的灰阶值数量较多，绑点分布较为分散，例如图3中的绑点1、绑点2、绑点3等。
另外，对于伽马曲线中亮度随灰阶值的变化较大的部分，分割的绑点数量较多，即每个绑点之间间隔的灰阶值数量较少，绑点分布较为密集，例如图3中的绑点28、绑点29、绑点30等。
通过对比可以看出，图3中绑点1、绑点2、绑点3之间间隔的灰阶值数量(即各绑点在横轴的距离)，多于绑点28、绑点29、绑点30之间间隔的灰阶值数量。
然后，显示控制装置将曲线段进行分组，图4为本申请实施例提供的一种伽马曲线的示意图。在图4所示的伽马曲线的示意图中，第1个曲线段至第15个曲线段构成第一显示区的伽马曲线，而第16个曲线段至所述第30个曲线段构成第二显示区的伽马曲线。即，第1个曲线段至第N/2个曲线段构成第一显示区的伽马曲线，而第N/2+1个曲线段至所述第N个曲线段构成第二显示区的伽马曲线。
再然后，还需对伽马曲线的整体在亮度(显示电压)的维度上进行平移，以使该两个伽马曲线的亮度(显示电压)保持近似。
在实际使用时，由于前述的两个伽马曲线是通过对于预设的伽马曲线(255灰阶)进行分割得到的，即在每一伽马曲线中，其对应的灰阶是不完整的。
如图4所示的，该曲线是基于第1个曲线段至第15个曲线段构成的第一显示区的伽马曲线，即其在预设的伽马曲线中对应着从128灰阶值至255灰阶值的亮度。也就是说，其曲线的横坐标(灰阶值)的原点为128，而非0。
但是，显示控制装置获取的第一显示区的待显示数据的灰阶值是无法确定的，其有可能处于该第一显示区的伽马曲线的范围，如244；也有可 能超出第一显示区的伽马曲线的范围，如100。
因此，在本实施例中，为了避免超出伽马曲线的灰阶值范围的问题，以第一显示区为设置有屏下摄像头的区域为例，在显示控制装置获取到第一显示区的待显示数据时，还会将其灰阶值进行减半处理，得到第一处理结果。然后在第一处理结果的基础上加预设常数，得到第二处理结果，第二处理结果为处理后的灰阶值，从而，可以使处理后的灰阶值属于该第一显示区的伽马曲线的灰阶值范围。该预设常数可以为所有灰阶值的中间值，例如，所有灰阶值包括0-255总共256个值，则中间值为第128个灰阶值，即预设常数可以为127。
例如，前述的245的灰阶值，将变为244/2+127＝249；又如前述的100的灰阶值，将变为100/2+127＝177。
类似的，如图4所示的，该曲线是基于第16个曲线段至第30个曲线段构成的第二显示区的伽马曲线，即其在预设的伽马曲线中对应着从1灰阶值至127灰阶值的亮度。也就是说，其曲线的横坐标(灰阶值)的原点为0。
但是，显示控制装置获取的第二显示区的待显示数据的灰阶值是无法确定的，其有可能处于该第二显示区的伽马曲线的范围，如4；也有可能超出第一显示区的伽马曲线的范围，如144。
因此，在本实施例中，为了避免超出伽马曲线的灰阶值范围的问题，以第二显示区为设置有屏下摄像头的区域以外的区域为例，在显示控制装置获取到第二显示区的待显示数据时，还会将其灰阶值进行减半处理，得到第三处理结果，第三处理结果为处理后的灰阶值，从而，可以使处理后的灰阶值属于该第二显示区的伽马曲线的灰阶值范围。
例如，前述的4的灰阶值，将变为4/2＝2；又如前述的144的灰阶值，将变为144/2＝72。
因此，在本实施例中，显示控制装置还将根据待显示数据所属于的显示区，确定该显示区对应的灰阶转换处理算法；利用所述灰阶转换处理算法对所述待显示数据中的当前灰阶值进行灰阶转换处理，获得待显示数据的灰阶值。
在其中一种产品结构的实现方式中，所述第一显示区为设置有屏下摄 像头的区域，所述第二显示区为未设置屏下摄像头的区域，那么第一显示区的第一显示电压高于所述第二显示区的第二显示电压。
本申请提供的显示方法，通过对于待显示数据进行灰阶转换处理，以使得针对于显示面板上不同显示区的待显示数据的灰阶值，采用不同的伽马曲线进行灰阶值的映射，以得到可用于控制显示区显示亮度的显示电压，而采用这样的分区的显示控制方式，能够有效对于保证不同显示区的显示亮度维持在相同或相似的水平，特别针对于安装有屏下摄像头的显示面板，显示质量明显得到提升。
