 本发明的实施方式
为使本申请的目的、技术方案及效果更加清楚、明确，以下参照附图并举实施例对本申请进一步详细说明。应当理解，此处所描述的具体实施例仅用以解释本申请，并不用于限定本申请。
在现有的显示面板中，为了保证产品的显示均一性，对于不同的扫描线其所对应的子像素的充电时间相同。而随着显示面板尺寸的增加，数据线的电阻以及电容耦合效应对后面行的子像素的充电时间有较大的影响，因此在同一列的子像素中，不同行的子像素的充电时间可能出现差异，使得显示面板显示不均，影响显示面板的品质。基于此，本申请提出了一种显示面板亮度调节方法及装置以解决上述技术问题。
请参阅图1，本申请提供了一种显示面板亮度调节方法，其包括：
S10、获取目标面板在至少两条扫描线上第k个子像素的第一亮度值；
在本实施例中，步骤S10可以包括：
S101、获取所述目标面板在第i条扫描线上第k个子像素的第一亮度参数；
S102、获取所述目标面板在第j条扫描线上第k个子像素的第二亮度参数；
在本实施例中，所述第一亮度参数和所述第二亮度参数包括灰阶值、充电时间或充电电压中的至少一者，i和j为正整数。
在本实施例中，随着显示面板尺寸的增加，数据线电阻电容的影响逐渐明显，导致同一列数据线对应的子像素出现不同的亮度值，因此申请通过获取上述同一条数据线中不同行子像素的亮度参数作为参考值，以确定目标位置的像素所要达到的目标亮度，而能够反映亮度的相关参数可以为灰阶值、像素充电时间或充电电压等，本实施例不作具体限定。
S20、根据所述第一亮度值，确定所述目标面板在参考扫描线上第k个子像素的参考亮度值。
在本实施例中，步骤S20可以包括：
S201、获取所述第一亮度参数和所述第二亮度参数的第一均值；
S202、根据所述第一均值确定所述目标面板在参考扫描线上第k个子像素的参考亮度值。
在本实施例中，本步骤主要获取任一条数据线对应的子像素的参考亮度，其根据该条数据线上不同行的子像素的亮度参数来确定。例如，当第一亮度参数和第二亮度参数为灰阶值时，即根据不同行子像素所对应的第一灰阶值和第二灰阶值的均值来确定对应的参考灰阶值，在进行其他行子像素的亮度调节时，直接对子像素的灰阶值进行调节即可。或者，当第一亮度参数和第二亮度参数为充电时间，即根据不同行子像素所对应的第一充电时间和第二充电时间来确定对应的参考充电时间，在进行其他行子像素的亮度调节时，直接对子像素的充电时间进行调节即可。或者，当第一亮度参数和第二亮度参数为充电电压时，即根据不同行子像素所对应的第一充电电压和第二充电电压来确定对应的参考充电电压，在进行其他行子像素的亮度调节时，直接对子像素的充电电压进行调节即可。
本实施例主要通过不同子像素的均值来确定对应的参考值，而不同子像素的数量不限于本申请的两个，其可以为多个。或者，当某一个子像素的亮度参数为标准参数时，其可以以该子像素的亮度参数为参考参数。
在本实施例中，步骤S20还可以包括：
S211、根据所述第一亮度参数和所述第二亮度参数，获取亮度参数与第n条扫描线的关系曲线。
S212、基于亮度参数与第n条扫描线的关系曲线，根据所述目标面板的目标扫描线，确定所述目标面板在参考扫描线上第k个子像素的参考亮度值，n为正整数。
在上述步骤中，第一亮度参数和第二亮度参数的均值来确定参考亮度可能出现一定的误差，因此本步骤通过第一亮度参数和第二亮度参数确定亮度参数与第n条扫描线的关系曲线。例如，对于同一条数据线中，第五条扫描线所对应的子像素的亮度为M1，第10条扫描线所对应的子像素的亮度为M2，根据二次函数获取对应的函数f（x，y），x为具体的扫描线行数，y为对应的亮度值。而目标扫描线的行数是确定的，即x为已知量，只需要获取对应的y即可。
在本实施例中，为了保证函数f（x，y）可以根据对个子像素的参数进行确定，从而进行曲线的拟合。其次，y还可以为对应子像素的充电时间或充电电压等，此处不作具体限定。
在上述实施例的基础上，其还可以根据历史数据来获取所述目标面板在参考扫描线上第k个子像素的参考亮度值。例如根据上一调节周期的不同子像素的亮度值获取对应的关系曲线，本次调节周期根据该关系曲线获取参考扫描线上第k个子像素的参考亮度值。
S30、获取所述目标面板在目标扫描线上第k个子像素的第二亮度值。
在本步骤中，其主要通过获取本次调节周期的在目标位置上的子像素的亮度值。例如，对于第5条数据线所连接的子像素，已知第5行和第10行子像素的亮度值，而本申请的目标位置的子像素为除第5行和第10行子像素外的所有行的子像素的亮度为待调节亮度。最后，由于本次周期对应的亮度已经显示，因此对于亮度的调节只能处于下一调节周期中，本次调节周期仅仅获取对应的待调节值。
S40、若所述第二亮度值与所述参考亮度值不相等，根据所述第二亮度值与所述参考亮度值的差值，确定所述目标面板在目标扫描线上第k个子像素的目标亮度值，k为正整数。
在本步骤中，由于需要将目标扫描线上第k个子像素的亮度值调节至与参考亮度，因此本次调节周期主要是获取目标扫描线上第k个子像素的待调节量，以在下一测量周期中使得同一条数据线上连接的子像素的亮度相同。
在本实施例中，步骤S40可以包括：
S401、根据所述参考亮度值，确定所述参考扫描线上第k个子像素的参考充电时间；
S402、根据所述第二亮度值，确定所述目标扫描线上第k个子像素的待调节充电时间；
S403、调节所述待调节充电时间，以使所述待调节充电时间达到与所述参考充电时间的差值小于第一阈值的目标充电时间；
S404、所述目标扫描线上第k个子像素根据所述目标充电时间确定所述目标亮度值。
在本步骤中，其主要是通过不同子像素的充电时间的差异来调节同一列数据线的充电时间。例如请参阅图2，对于像素A，在Data线处于第一高电平和Gate线处于第二高电平时，像素A将处于充电状态，图中T1为其充电时间；对于像素B，由于Data线的上升沿时刻先于Gate线的上升沿时刻，Data线的下降沿时刻后于Gate线的下降沿时刻，因此像素B的充电时间T2远远大于像素A的充电时间，导致像素B的亮度值大于像素A的亮度值。
而在本实施例中，本申请通过确定像素A的充电时间，进而确定像素B的充电时间，根据二者充电时间相等的前提条件调节像素B的充电时间。
而对于具体的调节方式，在本实施例中，步骤S403可以包括：
S40311、获取所述待调节充电时间的截止时刻；
S40312、根据所述参考充电时间以及所述待调节充电时间的第一截止时刻，确定所述待调节充电时间的第一起始时刻；
S40313、根据所述第一起始时刻和所述第一截止时刻，确定所述目标面板在目标扫描线上第k个子像素的目标亮度值。
在本实施例中，步骤S40还包括：
S405、获取所述目标扫描线上第k个子像素的初始充电的第二起始时刻；
S406、根据所述第一起始时刻和所述第二起始时刻，确定所述目标扫描线上第k个子像素的数据电压在所述第一起始时刻和所述第二起始时刻之间的下降沿的第三起始时刻；
其中，所述第一起始时刻与所述第三起始时刻的差值不大于所述第二起始时刻与所述第三起始时刻的差值。
请参阅图3，本申请通过确定像素A的充电时间，进而根据像素B的充电截止时间及像素A的充电时间确定像素B的充电起始时间，以保证像素A和像素B的充电时间相同。对于像素A，起始充电时刻为t1，截止充电时刻为t2，对于像素B，其同时存在初始充电起始时刻t3、初始充电截止时刻t4、起始充电时刻t5和截止充电时刻为t6，t3为第二起始时刻，t4为第三起始时刻，t5为第一起始时刻，t6为第一截止时刻，而t5~t6为像素B的充电时间T2，因此为了保证T2与T1相等，t5的需要根据T1进行选择。
请参阅图4，图4为本申请显示面板亮度调节的另一种时序图，不同行的电压是无缝连接的，本申请的一行电压结束后，恢复至CFcom或0灰阶时（0即L1）的电压，再输出下一行电压，相当于用CFcom电压或0灰阶电压把相邻两个数据电压隔开，因此存在两个上升沿。其次，两次上升沿的电压跟灰阶大小有关，不一定相等。图4中的调节方式与图3中的相同，本申请不作详细介绍。
请参阅图5，其同样可以调节Gate线上升沿的时刻来对像素B的充电时间进行调整，或者二者进行同步调节。
在本实施例中，步骤S403还可以包括：
S40321、获取所述待调节充电时间的第一充电电压；
S40322、根据所述第一充电电压、所述参考充电时间以及所述参考亮度值，确定所述充电电压、充电时间以及子像素亮度的关联关系；
S40323、根据所述充电电压、充电时间以及子像素亮度的关联关系，基于所述待调节充电时间，确定所述目标充电时间和目标充电电压。
在本步骤中，由于子像素的亮度出了与充电时间有关之外，还与充电电压有关。例如，获取当获取需要达到的亮度值后，由于充电时间和充电电压呈负相关，因此为了避免充电时间过长或过短，其可以调节对应的充电电压，降低充电电压或提高充电电压。
本申请提出了一种显示面板亮度调节方法，其通过获取目标面板在至少两条扫描线上第k个子像素的第一亮度值；根据所述第一亮度值，确定所述目标面板在参考扫描线上第k个子像素的参考亮度值；获取所述目标面板在目标扫描线上第k个子像素的第二亮度值；若所述第二亮度值与所述参考亮度值不相等，根据所述第二亮度值与所述参考亮度值的差值，确定所述目标面板在目标扫描线上第k个子像素的目标亮度值。本申请根据多条扫描线上第k个子像素的亮度值确定目标扫描线上第k个子像素的目标亮度值，使得任一条数据线连接的子像素的亮度相同，提高了产品的显示均一性。
