LED显示屏具有亮度高、分辨率大、画质好等优点。随着LED显示屏技术的发展，出现了LED显示屏的灰度等级和像素密度不断提高、刷新频率越来越快的现象。
基于此，在LED显示屏的同一块灯板中，出现了AC(即，交流电)串扰所导致的高对比耦合现象。高对比耦合现象是LED显示屏的同一块灯板中，同一行的像素点之间的相互干扰造成的，具体表现为同一行的不同像素点的LED之间相互干扰造成的，比如，针对同一行的像素点，高亮区域像素点的LED干扰非高亮区域像素的LED，导致与高亮区域的像素点在同一行上的非高亮区域中像素点的亮度变暗，从而导致与高亮区域的像素点在同一行上的非高亮区域中像素点，比与高亮区域的像素点不在同一行上的非高亮区域中像素点的亮度低，也即，导致LED显示屏存在亮度不均匀的现象。

如图2所示，该亮度调节方法的具体流程如下：
S101、获取显示屏幕中像素点的亮度值。
其中，显示屏幕可以包括LED显示屏幕。

本申请实施例在对显示屏幕进行亮度调节之前，本申请实施例需要对本申请实施例的原理进行阐述。详见下述。
本申请实施例的显示屏幕可以为16bit位深的显示屏幕。如图3所示，本申请实施例的显示屏幕包括若干LED芯片，图中Dn表示LED芯片，n为正整数。显示屏幕包括若干像素点，每个像素点包括3个LED芯片，分别为R芯片、G芯片、B芯片。R芯片可以是指发红色光的LED芯片，G芯片可以是指发绿色光的LED芯片，B芯片可以是指发蓝色光的LED芯片。
例如，图3中包括6个像素点，分别为第一像素点，第二像素点、第三像素点、第四像素点、第五像素点，以及第六像素点。
其中，第一像素点包括D1、D2、D3，第二像素点包括D4、D5、D6，第三像素点包括D7、D8、D9；第四像素点包括D10、D11、D12，第五像素点包括D13、D14、D15，第六像素点包括D16、D17、D18。
与D1在同一列上的LED芯片均可以为发红色光的LED芯片，也即图3中，D1、D4、D7均为发红色光的LED芯片；与D2在同一列上的LED芯片均可以为发绿色光的LED芯片，也即，图3中，D2、D5、D8均为发绿色光的LED芯片；与D3在同一列上的LED芯片均可以为发蓝色光的LED芯片，也即图3中，D3、D6、D9均为发蓝色光的LED芯片。
与D10在同一列上的LED芯片均可以为发红色光的LED芯片，也即图3中，D10、D13、D16均为发红色光的LED芯片；与D11在同一列上的LED芯片均可以为发绿色光的LED芯片，也即图3中，D11、D14、D17均为发绿色光的LED芯片；与D12在同一列上的LED芯片均可以为发蓝色光的LED芯片，也即图3中，D12、D15、D18均可以为发蓝色光的LED芯片。
第一像素点、第二像素点，以及第三像素点均为高亮区域的像素点，第四像素点、第五像素点，以及第六像素点均为非高亮区域的像素点。
开启显示屏幕时，如果同时开启高亮区域和非高亮区域，由于高亮区域的像素点和非高亮区域的像素点之间会存在耦合现象，例如，高对比耦合现象，也即同一行上，高亮区域的像素点和非高亮区域的像素点之间相互干扰，导致非高亮区域中的像素点存在亮度不均匀的现象，也即导致显示屏幕存在亮度不均匀的现象。
例如，第一像素点和第四像素点位于同一行上，第一像素点为高亮区域的像素点，第四像素点为非高亮区域的像素点，第一像素点中的LED芯片会干扰第四像素点中的LED芯片，导致第四像素点中的LED芯片两端的电势差变小，从而导致第四像素点中的LED芯片变暗。
基于上述，本申请实施例进行改进，详见下述。
本申请实施例可以预先控制开启显示屏幕中的高亮区域和非高亮区域中的发红色光的LED芯片。针对非高亮区域中的发红色光的LED芯片，本申请实施例可以控制非高亮区域中发红色光的LED芯片按照不同的亮度值发光，并可以通过亮度检测仪器测量出非高亮区域中发红色光的LED芯片的耦合亮度值。
在本申请实施例中，LED芯片的亮度值可以以灰阶表征，LED芯片的亮度值范围包括0-255级灰阶。本申请实施例可以控制非高亮区域中发红色光的LED芯片按照不同级的灰阶发光，并测量出非高亮区域中发红色光的LED芯片的耦合亮度值。
然后，本申请实施例可以控制显示屏幕只显示非高亮区域，不显示高亮区域。控制非高亮区域中发红色光的LED芯片按照不同级的灰阶发光，并测量出非高亮区域中发红色光的LED芯片的原始亮度值。

数据组，对比数据组包括同一级的灰阶下，非高亮区域中发绿色光的LED芯片的耦合亮度值，和非高亮区域中发绿色光的LED芯片的原始亮度值。
同理，改变上述开启非高亮区域中发红色光的LED芯片为开启非高亮区域中发蓝色光的LED芯片，重复上述过程，得到不同级的灰阶下，非高亮区域中发蓝色光的LED芯片的对比数据组，对比数据组包括同一级的灰阶下，非高亮区域中发蓝色光的LED芯片的耦合亮度值，和非高亮区域中发蓝色光的LED芯片的原始亮度值。
基于上述，本申请实施例可以通过改变高亮区域的宽度，不改变高亮区域的高度，从而来改变高亮区域占显示屏幕的宽度比例，获取不同宽度比例下，不同级灰阶对应的非高亮区域中发红色光的LED芯片的对比数据组、不同级灰阶对应的非高亮区域中发绿色光的LED芯片的对比数据组、不同级灰阶对应的非高亮区域中发蓝色光的LED芯片的对比数据组。
其中，本申请实施例可以设置若干宽度比例，宽度比例计算公式详见公式(1)：
X÷Y＝Z 公式(1)
其中，如图4所示，X表示高亮区域的宽度，Y表示显示屏幕的宽度，Z表示宽度比例，Z可以是五分之一、可以是四分之一、可以是三分之一、可以是二分之一等。
基于上述，本申请实施例可以计算相同宽度比例和相同级灰阶条件下，非高亮区域中发红色光的LED芯片的对比数据组之间的第一差值绝对值，也即，非高亮区域中发红色光的LED芯片的耦合亮度值，和非高亮区域中发红色光的LED芯片的原始亮度值之间的第一差值绝对值。
同理，本申请实施例可以计算相同宽度比例和相同级灰阶条件下，非高亮区域中发绿色光的LED芯片的对比数据组之间的第二差值绝对值，也即，非高亮区域中发绿色光的LED芯片的耦合亮度值，和非高亮区域中发绿色光的LED芯片的原始亮度值之间的第二差值绝对值。
同理，本申请实施例可以计算相同宽度比例和相同级灰阶条件下，非高亮区域中发蓝色光的LED芯片的对比数据组之间的第三差值绝对值，也即，非高亮区域中发蓝色光的LED芯片的耦合亮度值，和非高亮区域中发蓝色光的LED芯片的原始亮度值之间的第三差值绝对值。
本申请实施例可以基于差值绝对值，确定耦合影响率，耦合影响率表征高亮区域和非高亮区域之间的耦合现象对非高亮区域中像素点的LED芯片的影响程度。差值绝对值包括第一差值绝对值、第二差值绝对值、第三差值绝对值。耦合影响率的计算如公式(2)所示：
A＝(B÷C)×100％ 公式(2)
其中，A表示耦合影响率，B表示差值绝对值，C表示非高亮区域中LED芯片的原始亮度值，LED芯片包括发红色光的LED芯片、发绿色光的LED芯片、发蓝色光的LED芯片。
其中，当A小于1％时，表示高亮区域和非高亮区域之间的耦合现象可以忽略不计。
本申请实施例可以将差值绝对值换算为以预设灰阶为单位的亮度值，预设灰阶以Gray表示。基于此，可以得到差值绝对值B＝kGray，其中，k为常数。
基于上述，本申请实施例对LED芯片进行亮度补偿的方式可以为：在非高亮区域中LED芯片的耦合亮度值的基础上，补偿差值绝对值，详见公式(3)：
NGray＝nGray+kGray 公式(3)
由于Gray为单位，基于此，可以将公式(3)简化为公式(4)：
N＝n+k 公式(4)
其中，N表示非高亮区域中LED芯片的补偿后亮度值；n表示非高亮区域中LED芯片的耦合亮度值；k表示非高亮区域中LED芯片的差值绝对值。
基于上述，本申请实施例通过在非高亮区域中LED芯片的原始亮度值的基础上，补偿差值绝对值后，可以减小甚至消除耦合效应对非高亮区域中LED芯片的影响。
基于上述，本申请实施例可以得到像素点的亮度补偿矩阵，参数矩阵详见下述：
其中，NRm表示在m级灰阶下，非高亮区域中亮度发红色光LED芯片的补偿后亮度值；NGm表示在m级灰阶下，非高亮区域中亮度发绿色光LED芯片的补偿后亮度值；NBm表示在m级灰阶下，非高亮区域中亮度发蓝色光LED芯片的补偿后亮度值。
其中，nrm表示在m级灰阶下，非高亮区域中亮度发红色光LED芯片的耦合亮度值；ngm表示在m级灰阶下，非高亮区域中亮度发绿色光LED芯片的耦合亮度值；nbm表示在m级灰阶下，非高亮区域中亮度发蓝色光LED芯片的耦合亮度值。
其中，krm表示在m级灰阶下，非高亮区域中亮度发红色光LED芯片的差值绝对值，也即补偿亮度值；kgm表示在m级灰阶下，非高亮区域中亮度发绿色光LED芯片的补偿亮度值；kbm表示在m级灰阶下，非高亮区域中亮度发蓝色光LED芯片的补偿亮度值。
其中，m表示灰阶级，m的取值范围为0-255。
当高亮区域的宽度改变的情况下，也即当宽度比例改变的情况下，像素点的亮度补偿矩阵中的元素的数值会产生变化。
本申请实施例中，每一像素点均对应有一亮度补偿矩阵集合。针对每一像素点对应的亮度补偿矩阵集合，亮度补偿矩阵集合包括每一宽度比例对应的亮度补偿矩阵。
本申请实施例中，计算机设备可以按照预设宽度比例，获取到预设宽度比例对应的非高亮区域中每一像素点对应的亮度补偿矩阵；生成第一关联关系集合，该第一关联关系集合包括每一像素点所在位置和亮度补偿矩阵之间的关联关系；生成第二关联关系集合，该第二关联关系集合包括预设宽度比例和第一关联关系集合之间的映射关系。
基于上述，本申请实施例可以对显示屏幕进行亮度调节，如图2所示，该亮度调节方法的具体流程可以如下：
S101、获取显示屏幕中像素点的亮度值。
其中，本申请实施例显示屏幕中像素点的亮度值以灰阶表示，例如，亮度值为60灰阶。
由于显示屏幕中像素点的亮度值由计算机设备控制，基于此，本申请实施例中，计算机设备获取到显示屏幕中像素点的亮度值。
除上述之外，本申请实施例还可以将计算机设备与亮度检测仪器连接，通过亮度检测仪器检测到显示屏幕中像素点的亮度值，并将显示屏幕中像素点的亮度值传输给计算机设备，基于此，计算机设备可以获取到显示屏幕中像素点的亮度值。
S102、根据像素点的亮度值，确定显示屏幕中的高亮区域和显示屏幕中的非高亮区域。
本申请实施例中，由于高亮区域对非高亮区域产生耦合效应，基于此，本申请实施例可以确定显示屏幕中的高亮区域和显示屏幕中的非高亮区域。
计算机设备根据像素点的亮度值，确定显示屏幕中的高亮区域和显示屏幕中的非高亮区域的方式可以如下：
例如，若像素点的亮度值大于或等于预设亮度阈值，则确定显示屏幕中存在高亮区域；将亮度值大于或等于预设亮度阈值的像素点作为高亮像素点，并根据高亮像素点所在位置，生成高亮区域；将亮度值小于预设亮度阈值的像素点作为非高亮像素点，并根据非高亮像素点所在位置，生成非高亮区域。
