具体实施方式
下面将结合附图，对本公开一些实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅仅是本公开一部分实施例，而不是全部的实施例。基于本公开所提供的实施例，本领域普通技术人员所获得的所有其他实施例，都属于本公开保护的范围。
叠屏是一种具有超高对比度的显示面板，如图1所示，采用叠屏的显示面板3包括叠加设置的显示子面板2和调光子面板1。使用背光模组4为显示面板3提供进行图像显示需要的光线，背光模组4设置于显示面板3的调光子面板1远离显示子面板2的一侧。如图2A和图2B所示，调光子面板1包括多个第一像素11，显示子面板2包括多个第二像素21。其中，如图3A所示，每个第一像素11与多个第二像素21相对应。此处，每个第一像素11与多个第二像素21“相对应”是指，每个第一像素11在显示子面板2上的正投影覆盖多个第二像素21中每个第二像素21的全部区域或部分区域，称该第一像素11与该第一像素11的投影所覆盖的多个第二像素21之间的关系为“相对应”。
需要说明的是，如图3A所示，在一些示例中，上述每个第一像素11所对应的多个第二像素21中，可以包括至少一个第二像素21的全部区域完全被相应的第一像素11在显示子面板2上的正投影覆盖，也可以包括至少一个第二像素21的部分区域被相应的第一像素11在显示子面板2上的正投影覆盖。所谓“至少一个第二像素21的部分区域”例如为，至少一个第二像素21中的各第二像素21的二分之一、三分之一，等等。
对于上述叠屏的显示面板3，背光模组4射出的背光穿过调光子面板1的每个第一像素11后，会穿过与每个第一像素11相对应的所述多个第二像素21。通过分别调节调光子面板1中各个第一像素11的灰阶，可以控制各个第一像素11允许透过的背光的亮度，从而实现将不同亮度的背光分区域提供给 显示子面板2，使得显示面板3显现较高的对比度和暗场细节。
由于调光子面板1中的每个第一像素11对应显示子面板2中的多个第二像素21，而所述多个第二像素21中的每个第二像素21的灰阶不同，因此，调光子面板1中的每个第一像素11的亮度不能做到与其对应的所述多个第二像素21中的每个第二像素21的亮度均一致。当每个第一像素11的亮度大于与其对应的所述多个第二像素21中的某一或某些第二像素21的亮度时，这些第二像素21的亮度就会偏亮；当每个第一像素11的亮度小于与其对应的所述多个第二像素21中的某一或某些第二像素21的亮度时，这些第二像素21显示的亮度就会偏暗。这就使得显示面板3在显示的图像中会出现虚影，从而导致显示面板3出现光晕的现象，造成显示质量下降。
在相关技术中，为改善显示面板3的光晕现象，会先获取与每个第一像素11对应的所述多个第二像素21中的每个第二像素21的灰阶数据；然后选取所述多个第二像素21的灰阶数据中最大的灰阶数据作为与所述多个第二像素21对应的第一像素11的灰阶数据。这样，通过使第一像素11的灰阶数据与其对应的所述多个第二像素21中的灰阶数据最大的第二像素21的灰阶数据相等，来避免显示子面板2中的第二像素21显示的亮度偏暗的问题，从而在一定程度上改善了显示面板3的光晕现象。
示例性的，如图3B和图3C所示，与调光子面板1的一个第一像素11对应的显示子面板2中的所述多个第二像素21的数量为20个，该20个第二像素21分别为P 01、P 02、P 03、P 04、P 1、P 2、……、P 15、P 16。其中，第二像素P 01、P 02、P 03、及P 04与第一像素11在显示子面板2上的正投影的重叠面积过小不予考虑，其余16个第二像素21(即P 1～P 16)的灰阶数据分别为80、90、97、100、156、110、115、70、120、125、110、135、98、100、150、140，该16个灰阶数据中最大的灰阶数据为156。如图3D所示，因此确定与该16个第二像素21对应的第一像素11的灰阶数据为156。
上述示例虽然可以避免显示子面板2中的第二像素21显示的亮度偏暗的问题，但是，由于每个第一像素11的灰阶数据与其对应的所述多个第二像素 21中灰阶数据最大的第二像素21的灰阶数据相同，因此，从另一个角度来讲，拉大了该第一像素11的灰阶数据与其对应的所述多个第二像素21中灰阶数据最小的第二像素21的灰阶数据之间的差值，造成显示子面板2中与该第一像素11对应的所述多个第二像素21中的部分第二像素21显示的亮度会更加偏亮。不仅如此，在同一显示面板3中，虽然第二像素21和第一像素11的灰阶数据相同，但是两者所对应的亮度可能并不相同。所以，采用第一像素11的灰阶数据和与其对应的多个第二像素21中的灰阶数据最大的第二像素21的灰阶数据相等这一技术方案，虽然在一定程度上能改善显示面板3出现光晕的现象，但对于光晕的改善效果并不是很理想。
为此，本公开的一些实施例提供了一种改善光晕的方法，参阅图1、图2A和图2B，该改善光晕的方法应用于显示面板3，该显示面板3为叠屏，包括叠加设置的调光子面板1和显示子面板2，调光子面板1包括多个第一像素11，显示子面板2包括多个第二像素21，每个第一像素11与至少两个第二像素21相对应。如图4所示，该改善光晕的方法包括：S100～S300。
S100，获取与第一像素11对应的所述至少两个第二像素21中的每个第二像素21的第二亮度数据。
S200，根据所获取的所述至少两个第二像素21中的每个第二像素21的第二亮度数据，计算第一像素11的目标亮度数据。
S300，根据目标亮度数据，确定第一像素11的第一灰阶数据。
需要说明的是，S100～S300仅是对于一个第一像素11来进行说明的，对于其他的第一像素11而言，改善光晕的方法的工作原理是一样的，在此不做赘述。
此处，第一灰阶数据为驱动调光子面板1中的第一像素11呈现灰阶的数据，不同的第一灰阶数据驱动调光子面板1中的第一像素11呈现不同的灰阶。例如，第一灰阶数据可以为驱动调光子面板1中的第一像素11呈现不同灰阶的电压值或电流值。下文将提及的第一亮度数据为第一像素11呈现第一灰阶时的亮度。
下文将提及的第二灰阶数据为驱动显示子面板2中的第二像素21呈现灰阶的数据，不同的第二灰阶数据驱动显示子面板2中的第二像素21呈现不同的灰阶。例如，第二灰阶数据可以为驱动显示子面板2中的每个第二像素21呈现不同灰阶的电压值或电流值。同样，第二亮度数据则为第二像素21呈现第二灰阶时的亮度。
在一些示例中，目标亮度数据为根据第一像素11对应的所述至少两个第二像素21中的每个第二像素21的第二亮度数据，及与每个第二像素21对应的亮度系数计算得到的亮度数据。其中，亮度系数为每个第二像素21与对应的第一像素11的重叠面积与该第一像素11的面积的比值。在第一像素11的面积不变的情况下，每个第二像素21与对应的第一像素11的重叠面积越大，则该第二像素21的亮度系数越大，其所对应的第二亮度数据在目标亮度数据中所占的比值就大，目标亮度数据就会与该第二亮度数据越接近。
例如，第一像素11对应6个第二像素21，这6个第二像素21的第二亮度数据分别为：100、156、110、115、80和114。通过这6个第二像素21的第二亮度数据，及与每个第二像素21对应的亮度系数计算得到的目标亮度数据为113(具体的计算方式可参见下文将提及的目标亮度数据的计算过程)，这样通过每个第二像素21的第二亮度数据，及各自的亮度系数所计算得到的目标亮度数据，与每个第二像素21的第二亮度数据均差距不大，从而能够从整体上或者大致从整体上反映第一像素11所对应的这6个第二像素21的亮度。
基于此，在本公开的上述实施例中，对于与第一像素11对应的所述至少两个第二像素21，先计算与所述至少两个第二像素21中的每个第二像素21的第二亮度数据均比较接近的第一像素11的目标亮度数据，再由第一像素11的目标亮度数据确定第一像素11的第一灰阶数据，这样，当第一灰阶数据驱动第一像素11呈现第一灰阶，每个第二灰阶数据驱动与第一像素11对应的所述至少两个第二像素21呈现第二灰阶时，第一灰阶所对应的目标亮度数据与每个第二灰阶数据所对应的第二亮度数据整体比较接近，这使得调光子面 板1中的第一像素11的亮度与其对应的所述至少两个第二像素21的亮度大约一致，从而改善了显示子面板2中的第二像素21显示的亮度偏暗或偏亮的情况，达到了改善显示面板3出现光晕的目的。
在一些实施例中，如图5所示，上述获取与第一像素11对应的所述至少两个第二像素21中的每个第二像素21的第二亮度数据的步骤(即S100)包括：S110和S120。
S110，获取与第一像素11对应的所述至少两个第二像素21中的每个第二像素21的第二灰阶数据。
S120，根据显示子面板2的第二灰阶数据与第二亮度数据的对应关系，获取与每个第二像素21的第二灰阶数据对应的第二像素21的第二亮度数据。
此处，可以分别测量显示子面板2的第二灰阶数据和与第二灰阶数据对应的第二亮度的对应的关系，获得显示子面板2的Gamma(伽马)曲线。
示例性的，假设显示子面板2可显示的灰阶数为256，则显示子面板2的第二灰阶数据与第二亮度数据的对应关系可如表格1所示。
表格1
第二灰阶数据 0 1 2 3 4 …… 254 255
第二亮度数据 0.26 0.36 0.42 0.48 0.54 …… 264.3 264.9
在一些实施例中，该显示子面板2的第二灰阶数据与第二亮度数据的对应关系为预先存储在显示面板3中的数据。这样，在执行S110和S120的过程中，可以通过直接调用预先存储的第二灰阶数据与第二亮度数据的对应关系数据，进而根据每个第二像素21的第二灰阶数据，获取与每个第二像素21的第二灰阶数据对应的第二亮度数据，提高显示装置的处理速度。
在本公开一些实施例中，如图5所示，上述根据所获取的所述至少两个第二像素21中的每个第二像素21的第二亮度数据，计算第一像素11的目标亮度数据的步骤(即S200)包括：S210～S230。
S210，获取所述至少两个第二像素21中的每个第二像素21的亮度系数； 亮度系数为相应的第二像素21和第一像素11的重叠面积与第一像素11的面积的比值。
这里，第一像素11的面积为第一像素11在显示子面板2上的正投影的面积。相应的第二像素21和第一像素11的重叠面积为，该第二像素21与第一像素11在显示子面板2上的正投影的重叠面积。
示例性的，如图3B所示，根据第一像素11在显示子面板2上的正投影所呈现的图形，测量该图形的几何数据，所述几何数据例如包括该图形的边长、相邻两条边长之间的夹角、弧长、或半径等，然后根据测量得到的该图形的几何数据计算该图形的面积X，面积X也即为第一像素11的面积。之后依次计算第一像素11对应的所述至少两个第二像素21中的每个第二像素21和第一像素11的重叠面积Y 1、Y 2、Y 3、……、Y i。这样，就可以计算得到每个第二像素21的亮度系数，第一像素11对应的所述至少两个第二像素21中的每个第二像素21的亮度系数为
Figure PCTCN2019111305-appb-000001
在一些实施例中，上述第一像素11对应的至少两个第二像素21中的每个第二像素21的亮度系数为预先存储在显示面板中的数据，以便于后续步骤中可以直接调用该预先存储的亮度系数数据，有利于提高显示装置的处理速度。
S220，将所述至少两个第二像素21中的每个第二像素21的亮度系数与相应的第二像素21的第二亮度数据相乘，得到所述至少两个第二像素21中的每个第二像素21的比例亮度数据。
在S220中，根据上述实施例获取的第一像素11对应的所述至少两个第二像素21中的每个第二像素21的第二亮度数据(例如，所述至少两个第二像素21的第二亮度数据分别为：L 1、L 2、L 3、……、L i)，及所述至少两个第二像素21中的每个第二像素21的亮度系数，计算得到所述至少两个第二像素21的比例亮度数据，分别为：
Figure PCTCN2019111305-appb-000002
S230，将所述至少两个第二像素21中的每个第二像素21的比例亮度数 据加和，得到第一像素11的目标亮度数据。
在S230中，示例性的，第一像素11的目标亮度数据为：
Figure PCTCN2019111305-appb-000003
可以理解的是，一个第二像素21与第一像素11的重叠面积越大，则该第二像素21的亮度需要第一像素11所贡献的亮度就越大；一个第二像素21与第一像素11的重叠面积越小，则该第二像素21的亮度需要第一像素11所贡献的亮度就越小。因此，本公开实施例中，以所述至少两个第二像素21中的每个第二像素21和第一像素11的重叠面积与第一像素11的面积的比值作为亮度系数，根据这些亮度系数计算第一像素11的目标亮度数据，能够使得调光子面板1中的第一像素11的目标亮度数据和显示子面板2中与第一像素11对应的多个第二像素21的第二亮度数据大约一致或比较接近，改善了显示子面板21中的第二像素21显示的亮度偏暗或偏亮的情况，达到改善显示面板3出现光晕的目的。
示例性的，如图3B所示，显示子面板2中的每个第二像素21的形状为矩形，每个第二像素21的长为B，每个第二像素21的宽为A，则每个第二像素21的面积：S 1＝AB。
调光子面板1中的每个第一像素11的形状为两个平行四边形拼接而成，每个第一像素11的面积可视为两个对称的平行四边形的面积之和，每个平行四边形的两条邻边的长度分别为C和D，该两条邻边之间的夹角的余角为α。这样就可得到一个平行四边形的面积：S 2＝CDcosα，从而即每个第一像素11的面积：S 3＝2CDcosα。
与调光子面板1的一个第一像素11对应的显示子面板2中的第二像素21的数量为20个，该20个第二像素分别为P 01、P 02、P 03、P 04、P 1、P 2、……、P 15、及P 16。
其中，第二像素P 01与第一像素11的重叠区域的形状为一个直角三角形， 假设该直角三角形的两条直角边的长度分别为
Figure PCTCN2019111305-appb-000004
则第二像素P 01与第一像素11的重叠面积为
Figure PCTCN2019111305-appb-000005
由于第一像素11的形状为两个平行四边形拼接而成，假设每个平行四边形为中心对称图形，则第二像素P 01、P 02、P 03、及P 04各自与第一像素11的重叠面积相等，均为

即：

对于第二像素P 1、P 2、P 15、及P 16，其各自与第一像素11的重叠面积为：

对于第二像素P 5、P 6、P 9、及P 14，其各自与第一像素11的重叠面积为：
S 8＝S P5＝S P6＝S P9＝S P14＝AB；   (5)
根据公式(1)～(5)计算得到第一像素11对应的20个第二像素P 01、P 02、P 03、P 04、P 1、P 2、……、P 15、及P 16各自与第一像素11的重叠面积，然后计算20个第二像素中每个第二像素的亮度系数。
对于第二像素P 01、P 02、P 03、及P 04，其亮度系数相等，均为：

对于第二像素P 1、P 2、P 15、及P 16，其亮度系数相等，均为：

对于第二像素P 3、P 8、P 11、及P 12，其亮度系数相等，均为：

对于第二像素P 4、P 7、P 10、及P 13，其亮度系数相等，均为：

对于第二像素P 5、P 6、P 9、及P 14，其亮度系数相等，均为：
Figure PCTCN2019111305-appb-000015
由上述第一像素11对应的20个第二像素的亮度系数，及其第二亮度数据L 01、L 02、L 03、……、L 16可计算得该第一像素11的目标亮度为：
Figure PCTCN2019111305-appb-000016
在一些实施例中，对于上述改善光晕的方法，若第一像素11对应的所述至少两个第二像素21中的一个第二像素21和第一像素11的重叠面积小于第一阈值，则令该第二像素21的亮度系数为0。例如，该第一阈值为所述至少两个第二像素21中的一个第二像素21的像素面积的1％～10％之间的任一数值。该第一阈值为一个第二像素21的像素面积的1％；该第一阈值为一个第二像素21的像素面积的5％；该第一阈值为一个第二像素21的像素面积的10％。
由于某一或某些第二像素21与第一像素11的重叠面积小于第一阈值，该第一阈值设置的较小(例如仅为一个第二像素21的像素面积的1％～10％)，这意味着某一或某些第二像素21与第一像素11的重叠面积较小，因此第二像素21的亮度系数较小，这使得该第二像素21的比例亮度数据较小，该第二像素21的比例亮度数据对于第一像素11的目标亮度数据的影响较小，因此在计算第一像素11的目标亮度数据时可以将与第一像素11的重叠面积小于第一阈值的第二像素21忽略不计。这样一来，可以减少第一像素11的目标亮度数据的计算量，简化的该计算过程，从而提高显示装置的处理速度。
示例性的，第一阈值为一个第二像素1的像素面积的10％，若第一像素11对应的所述至少两个第二像素21中的某个第二像素21和第一像素11的重叠面积小于一个第二像素21的像素面积的10％，则令该第二像素21的亮度 系数为0。例如，上述实施例中，第二像素P 01、P 02、P 03、及P 04的面积均为
Figure PCTCN2019111305-appb-000017
小于一个第二像素21的面积AB的10％，因此在获取第一像素11对应的所述至少两个第二像素21中的每个第二像素1的亮度系数时，可以不对第二像素P 01、P 02、P 03、及P 04的亮度系数进行获取。
在另一些实施例中，对于上述改善光晕的方法，若所述至少两个第二像素21中的一个第二像素21和第一像素11的重叠面积大于第二阈值，则该第二像素21的亮度系数为一个完整的第二像素21的面积与一个第一像素11的面积的比值。例如，该第二阈值为所述至少两个第二像素21中的一个第二像素21的像素面积的90％～99％之间的任一数值。该第二阈值为一个第二像素21的像素面积的90％；该第二阈值为一个第二像素21的像素面积的95％；该第二阈值为一个第二像素21的像素面积的99％。
由于某一或某些第二像素21和第一像素11的重叠面积大于第二阈值，该第二阈值设置的较大(例如为一个第二像素21的像素面积的90％～99％)，这意味着某一或某些第二像素21与第一像素11的重叠面积较大，因此第二像素21的亮度系数较大，这使得该第二像素21的比例亮度数据较大，该第二像素21的比例亮度数据对于第一像素11的目标亮度数据的影响较大，因此在计算第一像素11的目标亮度数据时，可以将与第一像素11的重叠面积大于第二阈值的第二像素21，按照一个完整的第二像素21的面积与一个第一像素11的面积的比值计算。这样一来，减小了第一像素11的目标亮度数据的计算量，从而提高显示装置的处理速度。
示例性的，第二阈值为一个第二像素21的像素面积的90％，若第一像素11对应的所述至少两个第二像素21中的某个第二像素21和第一像素11的重叠面积大于一个第二像素21的像素面积的90％，则令该第二像素21的亮度系数为一个第二像素21的面积与第一像素11的面积的比值。例如，上述实施例中，第二像素P 4、P 7、P 10、及P 13的面积均为
Figure PCTCN2019111305-appb-000018
大于一个第二像素21的面积AB的90％，因此在获取第一像素11对应的所述至少两个第二像素 21中的每个第二像素21的亮度系数时，可以直接将第二像素P 4、P 7、P 10、及P 13与第一像素11的重叠面积按AB进行计算，也即，S 7＝S 8＝S P4＝S P7＝S P10＝S P13＝S P5＝S P6＝S P9＝S P14＝AB。
这样，根据上述实施例可知，第二像素P 1、P 2、P 15、及P 16的亮度系数均为：
Figure PCTCN2019111305-appb-000019
第二像素P 3、P 8、P 11、及P 12的亮度系数均为：
Figure PCTCN2019111305-appb-000020
第二像素P 4、P 5、P 6、P 7、P 9、P 10、P 13及P 14的亮度系数均为：
Figure PCTCN2019111305-appb-000021
根据下文将提及的显示子面板2的第二灰阶数据与第二亮度数据对应关系表，可查得第二像素P 1、P 2、P 3、……、P 15、及P 16的第二亮度数据分别为L 1、L 2、L 3、……、L 15、及L 16，则调光子面板1的目标亮度数据的计算公式为：
Figure PCTCN2019111305-appb-000022
在公式(6)中，L Sub即为调光子面板1的目标亮度数据。
由于显示装置中预先存储的调光子面板1的第一灰阶数据与第一亮度数据的对应关系表中的数据均为固定值，因此，根据上述公式(6)得到调光子面板1的目标亮度数据L Sub很可能与对应关系表中的第一亮度数据不能完全相符，因此，需要在对应关系表中获取一个与调光子面板1的目标亮度数据L Sub最为接近的第一亮度数据。
在一些实施例中，如图5所示，上述根据目标亮度数据，确定第一像素11的第一灰阶数据包括：S310～S320。
S310，在第一像素11的多个第一亮度数据中，确定与第一像素11的目标亮度数据差值的绝对值最小的第一亮度数据。
S320，根据调光子面板1的第一灰阶数据与第一亮度数据的对应关系， 获取与所确定的第一亮度数据对应的第一灰阶数据，将所获取的第一灰阶数据作为第一像素11的第一灰阶数据。
此处，可以分别测量调光子面板1的第一灰阶数据和与第一灰阶数据对应的第一亮度的对应的关系，获得调光子面板1的Gamma(伽马)曲线。
示例性的，假设调光子面板1可显示的灰阶数为256个，则调光子面板1的第一灰阶数据与第一亮度数据的对应关系可如表格2所示。
表格2
第一灰阶数据 0 1 2 3 4 …… 254 255
第一亮度数据 0.20 0.23 0.27 0.30 0.35 …… 266.4 266.8
在一些实施例中，该调光子面板1的第一灰阶数据与第一亮度数据的对应关系为预先存储在显示面板3中的数据。这样，在执行S310和S320的过程中，可以直接调用预先存储的第一灰阶数据与第一亮度数据的对应关系，得到第一像素11的多个第一亮度数据，进而根据每个第一像素11的第一亮度数据，获取与每个第一像素11的第一亮度数据对应的第一灰阶数据，提高显示装置的处理速度。
在一些实施例中，若上述调光子面板1的第一灰阶数据与第一亮度数据的对应关系中所包括的各第一亮度数据中，与第一像素11的目标亮度数据差值的绝对值最小的第一亮度数据包括两个第一亮度数据，则从两个第一亮度数据中选择一个第一亮度数据。例如，从所述两个第一亮度数据中选择较大的一个第一亮度数据；或者，从所述两个第一亮度数据中选择较小的一个第一亮度数据。
示例性的，根据上述公式(6)得到调光子面板1的目标亮度数据L Sub，与调光子面板1的目标亮度数据L Sub最为接近的第一亮度数据L i可依据
Figure PCTCN2019111305-appb-000023
得到，其中，ΔL为L 1～L 255各自与L Sub的差值中的最小值。
与调光子面板1的目标亮度数据L Sub差值最小的第一亮度数据所对应的第 一灰阶数据，即为所需要的第一灰阶数据。需要说明的是，如果存在两个第一亮度数据L i和L i+1，其与L Sub的差值绝对值相等，则可以从两个第一亮度数据中任一选择一个第一亮度数据。
例如，可以定义两个第一亮度数据中数值较小的为与调光子面板1的目标亮度数据L Sub为最接近的第一亮度数据，即选择第一亮度数据L i作为与调光子面板1的目标亮度数据L Sub为最接近的第一亮度数据，第一亮度数据L i所对应的第一灰阶数据G i为所需要的第一灰阶数据。
或者，可以定义两个第一亮度数据中数值最大的为与调光子面板1的目标亮度数据L Sub为最接近的第一亮度数据，即选择第一亮度数据L i+1作为与调光子面板1的目标亮度数据L Sub为最接近的第一亮度数据，第一亮度数据L i+1所对应的第一灰阶数据G i+1即为所需要的第一灰阶数据。
值得一提的是，上述各实施例所涉及的调光子面板1中的第一像素11的形状是以图1A中所示出的形状进行说明的，显示子面板2中的第二像素21的形状是以图1B中所示出的形状进行说明的。但本公开中改善光晕的方法并不局限于此，对于其他形状的第一像素11和其他形状的第二像素21，本公开中的改善光晕的方法同样适用，同样能够改善显示面板3的光晕问题。
如图6所示，本公开的一些实施例提供了一种改善光晕的装置5，该改善光晕的装置5包括：处理器52和存储器51。
其中，处理器52与显示面板3电连接。
存储器51中存储有适于上述处理器52执行的计算机程序指令，该计算机程序指令被处理器52运行时执行如上述任一项实施例所述的改善光晕的方法中的一个或多个步骤。
这样，通过处理器52先确定与每个第二像素21的第二亮度数据均比较接近的第一像素11的目标亮度数据，再由第一像素11的目标亮度数据确定第一像素11的第一灰阶数据。当第一灰阶数据驱动第一像素11呈现第一灰阶，每个第二灰阶数据驱动与第一像素11对应的所述至少两个第二像素21 呈现第二灰阶时，第一灰阶所对应的目标亮度数据与每个第二灰阶数据所对应的第二亮度数据整体比较接近，这使得调光子面板1中的第一像素11的亮度和与其对应的所述至少两个第二像素21的亮度大约一致，从而改善了显示子面板2中的第二像素显示的亮度偏暗或偏亮的情况，达到了改善显示面板3出现光晕的目的。
上述处理器52可以是中央处理单元(Central Processing Unit，简称CPU)，还可以是其他通用处理器、数字信号处理器(DSP)、专用集成电路(ASIC)、现场可编程门阵列(FPGA)或者其他可编程逻辑器件、分立门或者晶体管逻辑器件、分立硬件组件等。其中，通用处理器可以是微处理器或者该处理器也可以是任何常规的处理器等。
存储器51用于存储本公开实施例提供的上述改善光晕的装置5的程序代码和数据。处理器可以通过运行或执行存储在存储器51内的软件程序，以及调用存储在存储器51内的数据，执行改善光晕的装置5的各种功能。
存储器可以是只读存储器(Read-Only Memory，ROM)或可存储静态信息和指令的其他类型的静态存储设备，随机存取存储器(Random Access Memory，RAM)或者可存储信息和指令的其他类型的动态存储设备，也可以是电可擦可编程只读存储器(Electrically Erasable Programmable Read-Only Memory，EEPROM)、只读光盘(Compact Disc Read-Only Memory，CD-ROM)或其他光盘存储、光碟存储(包括压缩光碟、激光碟、光碟、数字通用光碟、蓝光光碟等)、磁盘存储介质或者其他磁存储设备、或者能够用于携带或存储具有指令或数据结构形式的期望的程序代码并能够由计算机存取的任何其他介质，但不限于此。存储器51可以是独立存在，通过通信总线与处理器52相连接。存储器51也可以和处理器52集成在一起。
在一些实施例中，上述存储器51中还存储有每个第一像素11对应的所述至少两个第二像素中的每个第二像素的亮度系数数据、显示子面板2的第二灰阶数据与第二亮度数据的对应关系数据、及调光子面板1的第一灰阶数据与第一亮度数据的对应关系数据中的至少一者。这样，在处理器52执行改 善光晕的装置5的各种功能时，能够便于处理器52调用存储在存储器51内的各种数据。
在本公开的一些实施例中，如图7所示，还提供了一种显示器10，该显示器10包括：显示面板3，及，与显示面板3电连接的如上述一些实施例所述的改善光晕的装置5。
此处，显示器10的有益效果和上述一些实施例所述的改善光晕的装置5的有益效果相同，此处不再赘述。
示例性的，显示器10可以作为手机、平板电脑、电视机、笔记本电脑、数码相框、导航仪等任何具有显示功能产品的显示屏。

其中，获取模块61，被配置为获取与每个第一像素11对应的所述至少两个第二像素21中的每个第二像素21的第二亮度数据。
计算模块62，被配置为根据获取模块61所获取的第二亮度数据，计算每个第一像素11的目标亮度数据。
确定模块63，被配置为根据计算模块62计算得到的每个第一像素11的目标亮度数据，确定每个第一像素11的第一灰阶数据。
基于此，在本公开的上述实施例中，通过计算模块62计算出与每个第二像素21的第二亮度数据均比较接近的第一像素11的目标亮度数据，再由确定模块63根据第一像素11的目标亮度数据确定第一像素11的第一灰阶数据，这样，当第一灰阶数据驱动第一像素11呈现第一灰阶，每个第二灰阶数据驱动与第一像素11对应的所述至少两个第二像素21呈现第二灰阶时，第一灰阶所对应的目标亮度数据与每个第二灰阶数据所对应的第二亮度数据整体比 较接近，这使得调光子面板1中的第一像素11的亮度与其对应的所述至少两个第二像素21的亮度大约一致，从而改善了显示子面板2中的第二像素21显示的亮度偏暗或偏亮的情况，达到了改善显示面板3出现光晕的目的。
