在阐述本申请实施例所提供的技术方案之前，为了便于对本申请实施例理解，本申请首先对相关技术中存在的问题进行具体说明：
如前所述，为了使得显示面板具有较高的屏占比，显示面板可以包括主屏和副屏，主屏和副屏均可以用于显示画面。除了显示画面之外，副屏下方可以设置摄像头，摄 像头透过副屏来获取外界的图像，这种设置在屏幕下方的摄像头称作屏下摄像头(Under Display Camera，UDC)，因此，副屏又可以称作UDC区域。
为了满足显示需求，在显示面板上市之前，通常需要对显示面板的主屏和副屏进行伽马调试，以确保显示面板的显示效果满足显示要求。
随着显示技术的发展，显示面板所支持的刷新率数量增多，如目前一些显示面板在原有刷新率(如60Hz)的基础上，又增加了120Hz和/或144Hz刷新率显示。这样，也就导致伽马调试由原来只需要对原有刷新率下的各个灰阶进行伽马调试的基础上，又新增了对120Hz和/或144Hz刷新率下的各个灰阶进行伽马调试，伽马调试时间在原有基础上增加了近一倍。因此，随着显示面板所支持的刷新率数量增多，显示面板的伽马调试过程所花费的时间越来越长，严重制约了显示面板的生产效率。
通过大量的单片显示面板的主屏和副屏伽马调试实验，本申请的发明人进一步研究发现主屏的寄存器值与副屏的寄存器值之间存在一定的线性关系，即一次函数关系y＝ax±b。图1为显示面板的主屏中的红色子像素对应的寄存器值与副屏中的红色子像素对应的寄存器值的线性关系示意图。图2为显示面板的主屏中的绿色子像素对应的寄存器值与副屏中的绿色子像素对应的寄存器值的线性关系示意图。图3为显示面板的主屏中的蓝色子像素对应的寄存器值与副屏中的蓝色子像素对应的寄存器值的线性关系示意图。
图1中横坐标x为主屏中的红色子像素对应的寄存器值，图1中纵坐标y为副屏中的红色子像素对应的寄存器值。图2中横坐标x为主屏中的绿色子像素对应的寄存器值，图2中纵坐标y为副屏中的绿色子像素对应的寄存器值。图3中横坐标x为主屏中的蓝色子像素对应的寄存器值，图3中纵坐标y为副屏中的蓝色子像素对应的寄存器值。如图1至图3所示，举例而言，例如在一次实验中，主屏中的红色子像素对应的寄存器值与副屏中的红色子像素对应的寄存器值之间的线性关系为：y＝1.0944x-67.988。主屏中的绿色子像素对应的寄存器值与副屏中的绿色子像素对应的寄存器值之间的线性关系为：y＝1.1204x-105.76。主屏中的蓝色子像素对应的寄存器值与副屏中的蓝色子像素对应的寄存器值之间的线性关系为：y＝1.0591x-50.761。由此可以看出，主屏中的红色子像素对应的寄存器值与副屏中的红色子像素对应的寄存器值之间存在线性关系，主屏中的绿色子像素对应的寄存器值与副屏中的绿色子像素对应的寄存器值之间存在线性关系，主屏中的蓝色子像素对应的寄存器值与副屏中的蓝色子像素对应的寄存器值之间存在线性关系。
鉴于发明人的上述研究发现，本申请实施例提供了一种伽马调试方法及装置、计算机可读存储介质，能够解决相关技术中存在的伽马调试时间长、显示面板的生产效率低的技术问题。
本申请实施例的技术构思在于：直接根据第一显示区的寄存器值与第二显示区的 寄存器值之间的线性关系以及第一显示区在目标灰阶下的第一寄存器值，确定第二显示区在目标灰阶下的目标寄存器值，无需再对目标灰阶下的第二显示区进行伽马调试，在保证第二显示区不偏色的同时，节省了第二显示区及整个显示面板的伽马调试时间，提高了显示面板的生产效率。
下面首先对本申请实施例所提供的伽马调试方法进行介绍。
本申请实施例提供的伽马调试方法可以应用于显示面板，显示面板可以包括第一显示区和第二显示区。其中，第一显示区和第二显示区均设置有像素，即第一显示区和第二显示区均可以显示画面。在一些示例中，第一显示区的透光率与第二显示区的透光率可以不同，例如第一显示区可以为上述的主屏(即正常显示区)，第二显示区可以为副屏(即UDC区域)。当然，在另一些示例中，第一显示区也可以为上述的副屏，第二显示区可以为主屏，本申请实施例对此不作限定。
图4为本申请实施例提供的伽马调试方法的一种流程示意图。如图4所示，本申请实施例提供的伽马调试方法可以包括以下步骤S101和S102。
S101、获取伽马调试后的第一显示区在目标灰阶下的第一寄存器值。
其中，目标灰阶可以为预设的多个灰阶中的任意灰阶，如0～254灰阶中的任意灰阶。在对第一显示区进行伽马调试后，第一显示区在各个灰阶下的寄存器值便可确定。其中，寄存器值即寄存器的寄存器值，如51寄存器的寄存器值。为了便于区分，这里将第一显示区在目标灰阶下的寄存器值称作第一寄存器值。
S102、根据预先确定的第一显示区的寄存器值与第二显示区的寄存器值之间的线性关系以及第一寄存器值，确定第二显示区在目标灰阶下的目标寄存器值。
如前所述，第一显示区的寄存器值与第二显示区的寄存器值之间存在线性关系。那么，在S102中，则可以根据第一显示区的寄存器值与第二显示区的寄存器值之间的线性关系以及第一显示区在目标灰阶下的第一寄存器值，计算得到第二显示区在目标灰阶下的目标寄存器值。
按照传统的伽马调试方式，不仅需要对多个灰阶下的第一显示区进行伽马调试，而且还需要对多个灰阶下的第二显示区进行伽马调试，因此，伽马调试时间较长，显示面板的生产效率较低。
本申请实施例的伽马调试方法，根据第一显示区的寄存器值与第二显示区的寄存器值之间的线性关系以及第一显示区在目标灰阶下的第一寄存器值，确定第二显示区在目标灰阶下的目标寄存器值，无需再对目标灰阶下的第二显示区进行伽马调试，在保证第二显示区不偏色的同时，节省了第二显示区及整个显示面板的伽马调试时间，提高了显示面板的生产效率。
根据本申请的一些实施例，可选地，第一显示区和第二显示区均可以包括n种颜色的子像素，第一寄存器值可以为与n种颜色子像素一一对应的第一子寄存器值，n为大 于或等于1的整数。
相应地，S102、根据预先确定的第一显示区的寄存器值与第二显示区的寄存器值之间的线性关系以及第一寄存器值，确定第二显示区在目标灰阶下的目标寄存器值，具体可以包括以下步骤：
对于n种颜色的子像素中任意第i种颜色的子像素，根据第一显示区中的第i种颜色的子像素的寄存器值与第二显示区中的第i种颜色的子像素的寄存器值之间的线性关系以及第i种颜色的子像素对应的第一子寄存器值，确定第二显示区中的第i种颜色的子像素在目标灰阶下的目标寄存器值。
即，对于不同颜色的子像素而言，不同颜色的子像素对应的上述线性关系可以是不同的。针对每种颜色的子像素，可以根据第一显示区中的该颜色的子像素的寄存器值与第二显示区中的该颜色的子像素的寄存器值之间的线性关系以及伽马调试后的第一显示区中的该颜色的子像素在目标灰阶下的第一子寄存器值，确定第二显示区中的该颜色的子像素在目标灰阶下的目标寄存器值。
在一些具体的示例中，可选地，例如第一显示区和第二显示区均可以包括3种颜色子像素，分别为红色子像素、绿色子像素和蓝色子像素。相应地，在S102中，针对红色子像素，可以根据第一显示区中的红色子像素的寄存器值与第二显示区中的红色子像素的寄存器值之间的线性关系以及伽马调试后的第一显示区中的红色子像素在目标灰阶下的第一子寄存器值，确定第二显示区中的红色子像素在目标灰阶下的目标寄存器值。针对绿色子像素，可以根据第一显示区中的绿色子像素的寄存器值与第二显示区中的绿色子像素的寄存器值之间的线性关系以及伽马调试后的第一显示区中的绿色子像素在目标灰阶下的第一子寄存器值，确定第二显示区中的绿色子像素在目标灰阶下的目标寄存器值。针对蓝色子像素，可以根据第一显示区中的蓝色子像素的寄存器值与第二显示区中的蓝色子像素的寄存器值之间的线性关系以及伽马调试后的第一显示区中的蓝色子像素在目标灰阶下的第一子寄存器值，确定第二显示区中的蓝色子像素在目标灰阶下的目标寄存器值。
需要说明的是，在其他实施例中，除了红色子像素、绿色子像素和蓝色子像素之外，第一显示区和第二显示区还可以包括其他颜色子像素，如白色子像素(W子像素)或者黄色子像素(Y子像素)，本申请实施例对此不作限定。当第一显示区和第二显示区还包括其他颜色的子像素时，第二显示区中的其他颜色的子像素在目标灰阶下的目标寄存器值也可以通过上述类似的方式确定，为了描述简洁，在此不再赘述。
如此一来，针对不同颜色的子像素，根据每种颜色的子像素各自对应的第一显示区的寄存器值与第二显示区的寄存器值的线性关系，分别计算第二显示区中的不同颜色的子像素在目标灰阶下的目标寄存器值，能够进一步提高最终得到的第二显示区中的不同颜色的子像素在目标灰阶下的目标寄存器值的准确性，保证第二显示区的亮度 和色度达到预期要求。
根据本申请的一些实施例，可选地，例如可以从投产数据(即历史数据)中调取多个显示面板的历史寄存器值，即包括每个显示面板的第一显示区的第一历史寄存器值和每个显示面板的第二显示区的第二历史寄存器值，然后通过曲线拟合直接得到显示面板的第一显示区的寄存器值与第二显示区的寄存器值之间的线性关系。在一些示例中，例如对于多个显示面板的第一显示区的第一历史寄存器值和多个显示面板的第二显示区的第二历史寄存器值，可以采用VBA(Visual Basic for Applications)编程快速得到显示面板的第一显示区的寄存器值与第二显示区的寄存器值之间的线性关系y＝ax±b。
然而，经本申请的发明人进一步研究发现，直接通过大数据的曲线拟合(如VBA编程)得到的线性关系y＝ax±b，运算出的第二显示区的寄存器值存在一定偏差，可能会存在第二显示区偏色的风险，具体参见下文分析。
图5为多个显示面板的第一显示区中的各个颜色的子像素对应的寄存器值与第二显示区中的各个颜色的子像素对应的寄存器值之间的线性关系的斜率示意图。图6为多个显示面板的第一显示区中的各个颜色的子像素对应的寄存器值与第二显示区中的各个颜色的子像素对应的寄存器值之间的线性关系的截距示意图。图5中的横坐标表示不同的显示面板，图5的纵坐标表示第一显示区中的各个颜色的子像素对应的寄存器值与第二显示区中的各个颜色的子像素对应的寄存器值之间的线性关系的斜率。图6中的横坐标表示不同的显示面板，图6的纵坐标表示第一显示区中的各个颜色的子像素对应的寄存器值与第二显示区中的各个颜色的子像素对应的寄存器值之间的线性关系的截距。
如图5所示，经本申请的发明人进一步发现，无论是红色子像素R，还是绿色子像素G和蓝色子像素B，不同显示面板对应的第一显示区的寄存器值与第二显示区的寄存器值的线性关系中的斜率相差较小，即斜率趋于稳定。如图6所示，无论是红色子像素R，还是绿色子像素G和蓝色子像素B，不同显示面板对应的第一显示区的寄存器值与第二显示区的寄存器值的线性关系中的截距相差较大，即不同显示面板对应的截距差别较大。
鉴于上述研究发现，本申请的发明人考虑到由于不同显示面板对应的线性关系的斜率相差较小，所以在确定目标显示面板对应的线性关系的斜率时，可以根据测试显示面板(即其他显示面板)的历史寄存器值确定目标显示面板对应的线性关系的斜率。而由于不同显示面板对应的线性关系的截距相差较大，所以在确定目标显示面板对应的线性关系的截距时，可以根据显示面板自身的第一显示区和第二显示区在某个灰阶下的寄存器值确定目标显示面板对应的线性关系的截距。这样，得到的目标显示面板的第一显示区的寄存器值与第二显示区的寄存器值的线性关系符合目标显示面板自身的实际情况，即具有较高的准确度，进而保证最终得到的目标寄存器值的准确性。
图7为本申请实施例提供的伽马调试方法的另一种流程示意图。如图7所示，根据本申请的一些实施例，可选地，在S101、获取伽马调试后的第一显示区在目标灰阶下的第一寄存器值之前，本申请实施例提供的伽马调试方法还可以包括以下步骤S701至S705。
S701、获取伽马调试后的多个测试显示面板的第一显示区的第一历史寄存器值和多个测试显示面板的第二显示区的第二历史寄存器值。
例如，在一些示例中，从投产数据(即历史数据)中调取了575个显示面板的历史寄存器值，即包括每个显示面板的第一显示区的第一历史寄存器值和每个显示面板的第二显示区的第二历史寄存器值。这里，为了便于区分，将调取的历史上已伽马调试完的显示面板称作测试显示面板。
S702、根据第一历史寄存器值和第二历史寄存器值，确定线性关系的斜率。
在得到伽马调试后的多个测试显示面板的第一显示区的第一历史寄存器值和多个测试显示面板的第二显示区的第二历史寄存器值之后，即得到多组(x1,y1)、(x2,y2)、(x3,y3)、……、(xn,yn)之后，可以通过曲线拟合或运算，得到显示面板对应的线性关系y＝ax±b的斜率a。
S703、获取伽马调试后的显示面板的第一显示区在第一灰阶下的第二寄存器值和伽马调试后的显示面板的第二显示区在第一灰阶下的第三寄存器值。
其中，第一灰阶可以为任意一个灰阶，如255灰阶。在S703中，可以对多个灰阶下的显示面板的第一显示区进行伽马调试，得到显示面板的第一显示区在多个灰阶下的寄存器值。这多个灰阶中可以包括第一灰阶，从而得到显示面板的第一显示区在第一灰阶下的寄存器值。这里，为了便于区分，将显示面板的第一显示区在第一灰阶下的寄存器值称作第二寄存器值。此外，还可以根据预设的目标亮度和目标色坐标对于第一灰阶下的显示面板的第二显示区进行伽马调试，得到显示面板的第二显示区在第一灰阶下的寄存器值。这里，为了便于区分，将显示面板的第二显示区在第一灰阶下的寄存器值称作第三寄存器值。
S704、根据第二寄存器值和第三寄存器值，确定线性关系的截距。
由于显示面板对应的线性关系y＝ax±b的斜率a已经确定，所以将第二寄存器值和第三寄存器值分别代入显示面板对应的线性关系y＝ax±b，便可以确定显示面板对应的线性关系的截距b。
S705、根据线性关系的斜率和截距，得到线性关系。
在显示面板对应的线性关系的斜率a和截距b均确定后，则可以得到显示面板对应的线性关系。
如此一来，本申请实施例根据测试显示面板的第一显示区和第二显示区的历史寄存器值，快速得到显示面板对应的第一显示区的寄存器值与第二显示区的寄存器值的 线性关系中的斜率；然后，再根据该显示面板自身的第一显示区和第二显示区在第一灰阶下的寄存器值，得到显示面板对应的第一显示区的寄存器值与第二显示区的寄存器值的线性关系中的截距，进而保证得到的第一显示区的寄存器值与第二显示区的寄存器值的线性关系符合显示面板自身的实际情况，即具有较高的准确度，进而保证最终得到的目标寄存器值的准确性。
根据本申请的一些实施例，可选地，目标灰阶可以为除第一灰阶之外的多个灰阶中的任意灰阶。例如，第一灰阶为255灰阶，那么目标灰阶可以为0～254灰阶中的任意灰阶。当然，在伽马调试过程中，通常会设置多个灰阶绑点，其中，第一灰阶可以作为一个灰阶绑点，而目标灰阶可以为除第一灰阶所在的灰阶绑点之外的其他多个灰阶绑点中的任意灰阶绑点，本申请实施例对此不作限定。
如此一来，对于除第一灰阶之外的其他多个灰阶，均通过第一显示区的寄存器值与第二显示区的寄存器值之间的线性关系确定第二显示区在各个灰阶的目标寄存器值，无需再对除第一灰阶之外的其他多个灰阶下的第二显示区进行伽马调试，在保证第二显示区不偏色的同时，大幅节省了第二显示区及整个显示面板的伽马调试时间，提高了显示面板的生产效率。
根据本申请的一些实施例，可选地，针对不同颜色的子像素，可以建立不同的线性关系。具体而言，第一显示区和第二显示区均可以包括n种颜色的子像素，n为大于或等于1的整数。
第一历史寄存器值可以为与n种颜色的子像素一一对应的第一子历史寄存器值，第二历史寄存器值可以为与n种颜色的子像素一一对应的第二子历史寄存器值。
相应地，S702、根据第一历史寄存器值和第二历史寄存器值，确定线性关系的斜率，具体可以包括以下步骤：
对于n种颜色的子像素中任意第i种颜色的子像素，根据多个测试显示面板中第i种颜色的子像素对应的第一子历史寄存器值和多个测试显示面板中第i种颜色的子像素对应的第二子历史寄存器值，确定子线性关系的斜率；子线性关系包括第一显示区中的第i种颜色的子像素的寄存器值与第二显示区中的第i种颜色的子像素的寄存器值之间的线性关系。
示例性地，第一显示区和第二显示区均可以包括3种颜色子像素，分别为红色子像素、绿色子像素和蓝色子像素。针对红色子像素，可以根据红色子像素对应的第一子历史寄存器值和红色子像素对应的第二子历史寄存器值，确定红色子像素对应的子线性关系的斜率。针对绿色子像素，可以根据绿色子像素对应的第一子历史寄存器值和绿色子像素对应的第二子历史寄存器值，确定绿色子像素对应的子线性关系的斜率。针对蓝色子像素，可以根据蓝色子像素对应的第一子历史寄存器值和蓝色子像素对应的第二子历史寄存器值，确定蓝色子像素对应的子线性关系的斜率。
第二寄存器值可以为与n种颜色的子像素一一对应的第二子寄存器值，第三寄存器值可以为与n种颜色的子像素一一对应的第三子寄存器值；
相应地，S704、根据第二寄存器值和第三寄存器值，确定线性关系的截距，具体可以包括以下步骤：
根据显示面板中第i种颜色的子像素对应的第二子寄存器值和显示面板中第i种颜色的子像素对应的第三子寄存器值，确定子线性关系的截距。
示例性地，针对红色子像素，可以根据红色子像素对应的第二子寄存器值和红色子像素对应的第三子寄存器值，确定红色子像素对应的子线性关系的截距。针对绿色子像素，可以根据绿色子像素对应的第二子寄存器值和绿色子像素对应的第三子寄存器值，确定绿色子像素对应的子线性关系的截距。针对蓝色子像素，可以根据蓝色子像素对应的第二子寄存器值和蓝色子像素对应的第三子寄存器值，确定蓝色子像素对应的子线性关系的截距。
相应地，S705、根据线性关系的斜率和截距，得到线性关系，具体可以包括以下步骤：
根据第i种颜色的子像素对应的子线性关系的斜率和第i种颜色的子像素对应的子线性关系的截距，得到第i种颜色的子像素对应的子线性关系。
示例性地，针对红色子像素，可以根据红色子像素对应的子线性关系的斜率和红色子像素对应的子线性关系的截距，得到红色子像素对应的子线性关系。针对绿色子像素，可以根据绿色子像素对应的子线性关系的斜率和绿色子像素对应的子线性关系的截距，得到绿色子像素对应的子线性关系。针对蓝色子像素，可以根据蓝色子像素对应的子线性关系的斜率和蓝色子像素对应的子线性关系的截距，得到蓝色子像素对应的子线性关系。
如此一来，针对不同颜色的子像素，分别根据测试显示面板的第一显示区和第二显示区中的各个颜色的子像素的历史寄存器值，快速得到显示面板中各个颜色的子像素对应的第一显示区的寄存器值与第二显示区的寄存器值的线性关系中的斜率；然后，再根据该显示面板自身的第一显示区和第二显示区中的各个颜色的子像素在第一灰阶下的寄存器值，得到显示面板中各个颜色的子像素对应的第一显示区的寄存器值与第二显示区的寄存器值的线性关系中的截距，进而保证得到的显示面板中各个颜色的子像素对应的第一显示区的寄存器值与第二显示区的寄存器值的线性关系符合显示面板自身的实际情况，即具有较高的准确度，进而保证最终得到的显示面板中各个颜色的子像素对应的目标寄存器值的准确性。
为了保证具有较好的显示效果，在伽马调试过程中，可以针对不同的刷新率和不同的亮度等级分别进行伽马调试。表1示意性示出了伽马调试过程所采取的灰阶绑点组数。
表1
Figure PCTCN2022134678-appb-000001
如表1所示，显示面板的亮度可以包括多个亮度等级，如2.2nit、6.1nit、10.3nit、20.4nit、51.2nit、122.7nit、306.7nit和460nit。显示面板可以支持多种刷新率显示，如60Hz和120Hz。那么，在伽马调试过程中，可以针对不同的刷新率和不同的亮度等级分别进行伽马调试。在表1中，Gamma02～Gamma10、Gamma42～Gamma50、Gamma22～Gamma30和Gamma62～Gamma70中的每个Gamma(i)均代表一组伽马段， 一组伽马段可以包括多个灰阶绑点。举例而言，例如Gamma02包括15个灰阶绑点，Gamma03包括15个灰阶绑点，……，Gamma70包括15个灰阶绑点。例如，在刷新率60Hz且亮度等级2.2nit下，主屏调试一组伽马段(即Gamma02)，副屏调试一组伽马段(即Gamma42)。在刷新率120Hz且亮度等级2.2nit下，主屏调试一组伽马段(即Gamma22)，副屏调试一组伽马段(即Gamma62)。若按照传统的伽马调试方式，整个伽马调试过程需要调试36组伽马段(即Gamma02～Gamma10、Gamma42～Gamma50、Gamma22～Gamma30和Gamma62～Gamma70)，伽马调试时间较长。
在本申请的一些实施例中，针对不同刷新率和不同亮度等级，分别确定不同刷新率且不同亮度等级下各自对应的线性关系，再根据各个刷新率且各个亮度等级下对应的线性关系分别确定第二显示区在各个刷新率且各个亮度等级对应的目标灰阶下的目标寄存器值，能够减少伽马调试所需的灰阶绑点的组数，减少伽马调试时间。
具体而言，根据本申请的一些实施例，可选地，每个亮度等级均可以对应M个灰阶，M为大于或等于1的整数。M的大小可以根据实际情况灵活调整，如M＝15，本申请实施例对此不作限定。
第一历史寄存器值可以包括多个测试显示面板的第一显示区在目标刷新率的多个亮度等级下的历史寄存器值，第二历史寄存器值可以包括多个测试显示面板的第二显示区在目标刷新率且多个亮度等级下的历史寄存器值，目标刷新率包括至少一个刷新率。例如，第一历史寄存器值可以包括多个测试显示面板的第一显示区在刷新率60Hz且亮度等级2.2nit下的历史寄存器值、在刷新率60Hz且亮度等级6.1nit下的历史寄存器值、……、在刷新率120Hz且亮度等级2.2nit下的历史寄存器值等。例如，第二历史寄存器值可以包括多个测试显示面板的第二显示区在刷新率60Hz且亮度等级2.2nit下的历史寄存器值、在刷新率60Hz且亮度等级6.1nit下的历史寄存器值、……、在刷新率120Hz且亮度等级2.2nit下的历史寄存器值等。
相应地，S702、根据第一历史寄存器值和第二历史寄存器值，确定线性关系的斜率，具体可以包括以下步骤：
根据第一显示区在任意第x个刷新率且第y个亮度等级下的历史寄存器值和第二显示区在任意第x个刷新率且第y个亮度等级下的历史寄存器值，确定第x个刷新率且第y个亮度等级对应的线性关系的斜率。
例如，根据多个测试显示面板的第一显示区在刷新率60Hz且亮度等级2.2nit下的历史寄存器值以及多个测试显示面板的第二显示区在刷新率60Hz且亮度等级2.2nit下的历史寄存器值，确定刷新率60Hz且亮度等级2.2nit对应的线性关系的斜率。例如，根据多个测试显示面板的第一显示区在刷新率60Hz且亮度等级6.1nit下的历史寄存器值以及多个测试显示面板的第二显示区在刷新率60Hz且亮度等级6.1nit下的历史寄存器值，确定刷新率60Hz且亮度等级6.1nit对应的线性关系的斜率。依次类推，在此不 再赘述。
第二寄存器值可以包括显示面板的第一显示区在目标个刷新率的多个亮度等级分别对应的第一灰阶下的寄存器值，第三寄存器值可以包括显示面板的第二显示区在目标刷新率的多个亮度等级分别对应的第一灰阶下的寄存器值。
相应地，S704、根据第二寄存器值和第三寄存器值，确定线性关系的截距，具体可以包括以下步骤：
根据第一显示区及第二显示区在第x个刷新率且第y个亮度等级对应的第一灰阶下的寄存器值，确定第x个刷新率且第y个亮度等级对应的线性关系的截距。
例如，根据显示面板的第一显示区在刷新率60Hz且亮度等级2.2nit对应的第一灰阶下的寄存器值以及显示面板的第二显示区在刷新率60Hz且亮度等级2.2nit对应的第一灰阶下的寄存器值，确定刷新率60Hz且亮度等级2.2nit对应的线性关系的截距。例如，根据显示面板的第一显示区在刷新率60Hz且亮度等级6.1nit对应的第一灰阶下的寄存器值以及显示面板的第二显示区在刷新率60Hz且亮度等级6.1nit对应的第一灰阶下的寄存器值，确定刷新率60Hz且亮度等级6.1nit对应的线性关系的截距。依次类推，在此不再赘述。
相应地，S705、根据线性关系的斜率和截距，得到线性关系，具体可以包括以下步骤：
根据第x个刷新率且第y个亮度等级对应的线性关系的斜率和截距，得到第x个刷新率且第y个亮度等级对应的线性关系。
例如，根据刷新率60Hz且亮度等级2.2nit对应的线性关系的斜率和刷新率60Hz且亮度等级2.2nit对应的线性关系的截距，得到刷新率60Hz且亮度等级2.2nit对应的线性关系。例如，根据刷新率60Hz且亮度等级6.1nit对应的线性关系的斜率和刷新率60Hz且亮度等级6.1nit对应的线性关系的截距，得到刷新率60Hz且亮度等级6.1nit对应的线性关系。依次类推，在此不再赘述。
根据本申请的一些实施例，可选地，第一寄存器值可以包括显示面板的第一显示区在目标刷新率的多个亮度等级分别对应的目标灰阶下的寄存器值。
相应地，S102、根据预先确定的第一显示区的寄存器值与第二显示区的寄存器值之间的线性关系以及第一寄存器值，确定第二显示区在目标灰阶下的目标寄存器值，具体可以包括以下步骤：
根据第x个刷新率且第y个亮度等级对应的线性关系以及第一显示区在第x个刷新率且第y个亮度等级对应的目标灰阶下的寄存器值，确定第二显示区在第x个刷新率且第y个亮度等级对应的目标灰阶下的目标寄存器值。
例如，根据刷新率60Hz且亮度等级2.2nit对应的线性关系以及显示面板的第一显示区在刷新率60Hz且亮度等级2.2nit对应的目标灰阶下的寄存器值，确定第二显示区 在刷新率60Hz且亮度等级2.2nit对应的目标灰阶下的目标寄存器值。例如，根据刷新率120Hz且亮度等级2.2nit对应的线性关系以及显示面板的第一显示区在刷新率120Hz且亮度等级2.2nit对应的目标灰阶下的寄存器值，确定第二显示区在刷新率120Hz且亮度等级2.2nit对应的目标灰阶下的目标寄存器值。依次类推，在此不再赘述。
如此一来，针对不同刷新率和不同亮度等级，分别确定不同刷新率且不同亮度等级下各自对应的线性关系，再根据各个刷新率且各个亮度等级下对应的线性关系分别确定第二显示区在各个刷新率且各个亮度等级对应的目标灰阶下的目标寄存器值，能够进一步提高最终得到的第二显示区在目标灰阶下的目标寄存器值的精准性。
结合上述表1所示，以第一显示区为主屏，第二显示区为副屏为例，在本申请实施例中，只需调试主屏对应的18组伽马段(即Gamma02～Gamma10和Gamma22～Gamma30)，以及副屏的18个第一灰阶(如18组伽马段中的255灰阶)，调试18个第一灰阶所需时间近似调试一组伽马段(如15个灰阶绑点)所需时间。因此，本申请实施例将由原本需要调试36组伽马段缩减为(18+1)组伽马段，大幅节省了伽马调试时间，极大提升了显示面板的生产效率。
在一些具体的示例中，结合不同颜色子像素，例如可以根据红色子像素在刷新率60Hz且亮度等级2.2nit对应的线性关系以及显示面板的第一显示区中的红色子像素在刷新率60Hz且亮度等级2.2nit对应的目标灰阶下的寄存器值，确定第二显示区中的红色子像素在刷新率60Hz且亮度等级2.2nit对应的目标灰阶下的目标寄存器值。例如可以根据红色子像素在刷新率120Hz且亮度等级2.2nit对应的线性关系以及显示面板的第一显示区中的红色子像素在刷新率120Hz且亮度等级2.2nit对应的目标灰阶下的寄存器值，确定第二显示区中的红色子像素在刷新率120Hz且亮度等级2.2nit对应的目标灰阶下的目标寄存器值。
例如可以根据绿色子像素在刷新率60Hz且亮度等级2.2nit对应的线性关系以及显示面板的第一显示区中的绿色子像素在刷新率60Hz且亮度等级2.2nit对应的目标灰阶下的寄存器值，确定第二显示区中的绿色子像素在刷新率60Hz且亮度等级2.2nit对应的目标灰阶下的目标寄存器值。例如可以根据绿色子像素在刷新率120Hz且亮度等级2.2nit对应的线性关系以及显示面板的第一显示区中的绿色子像素在刷新率120Hz且亮度等级2.2nit对应的目标灰阶下的寄存器值，确定第二显示区中的绿色子像素在刷新率120Hz且亮度等级2.2nit对应的目标灰阶下的目标寄存器值。
