图1为一个实施例中提供的背光校正方法的实施环境图，如图1所示，在该实施环境中，包括控制模块100、背光模块200以及检测模块300。
控制模块100为设置于显示设备中，对显示设备的其它元件起控制作用的模块，其可以为中央处理器(centralprocessingunit,CPU)、片上系统(SystemonChip,SoC)、图形处理器(graphicsprocessingunit,GPU)等芯片、集成电路或控制电路。背光模块200为给显示设备提供背光的模块，为显示设备的背光源。检测模块300为用于获取背光模块200的背光参数的模块，其朝向背光模块200设置。在使用过程中，控制模块100控制背光模块200点亮，然后通过检测模块300获取对应的背光参数，然后根据背光参数判断该显示设备的背光类型，并相应地对应背光校正的模式和参数。
需要说明的是，控制模块100、背光模块200以及检测模块300之间可以通过有线无线或者其他通讯连接方式进行连接，本发明在此不做限制。
如图2所示，在一个实施例中，提出了一种背光校正方法，所述背光校正方法可以应用于上述的控制模块100中，具体可以包括以下步骤：
步骤S100，获取所述显示设备的背光参数。
步骤S200，确定所述背光参数对应的背光类型。
步骤S300，根据所述背光类型对所述显示设备进行背光校正。
在本公开的实施例中，在确定该显示设备所采用的背光类型时，需要先电亮背光模块200后，通过检测模块300采集显示设备的背光参数。在获取相应地背光参数后，就可以根据背光参数来确定该显示设备所采用的背光类型，继而根据背光类型确定背光校正的模式。当其背光类型为传统背光时，采用传统的背光校正方式，对显示设备进行背光校正即可。当其背光类型为Mini-LED背光时，采用对应的新的背光校正方式，对显示设备进行背光校正即可。
本公开通过上述方案，自动分辨显示设备的背光类型，解决了现有技术中背光校正时容易出现参数误用的情况技术问题。
具体的，在一些实施例中，步骤S100的具体实施方式可以参阅图3。图3是根据图2对应实施例示出的背光校正方法中步骤S100的细节描述，所述背光校正方法中，检测模块300为可以检测单位区域内光亮面积的检测器，例如摄像设备以及红外设备等，检测模块300设置于所述显示设备的背光控制板上，所述背光控制板设置于所述显示设备的非显示区，步骤S100可以包括以下步骤：
步骤S101，驱动所述检测器正对的预定区域内的所有背光源。
步骤S102，获取所述预定区域的光亮图像；
步骤S103，根据所述光亮图像，确定所述背光参数。
在本实施例中，用来判断显示设备所采用的背光类型所依据的背光参数可以包括光亮面积占比以及光亮密度中的至少一个。
其中光亮面积占比的获取方式为，在点亮背光源后，通过检测模块300获取背光源的光亮图像，确定该光亮图像中光亮面积所占的比例，即得到光亮面积占比。
光亮密度的获取方式为，在点亮背光源后，通过检测模块300获取背光源的光亮图像，确定该光亮图像中光斑亮点的密度，即得到光亮密度。
在上述的检测过程中检测模块300需要设置于所述显示设备的背光控制板上，所述背光控制板设置于所述显示设备的非显示区，非显示区内设置有多个背光源。
在获取相应地背光参数后，就可以确定所述背光参数对应的背光类型。其具体方式可以参考图4和图5示出的实施例。
具体的，在一些实施例中，步骤S200的具体实施方式可以参阅图4。图4是根据图3对应实施例示出的背光校正方法中步骤S200的细节描述，所述背光校正方法中，所述背光参数包括光亮面积占比，步骤S200可以包括以下步骤：
步骤S201，若所述光亮面积占比小于预定占比阈值，则所述光亮面积占比对应第一背光类型。
步骤S202，若所述光亮面积占比大于预定占比阈值，则所述光亮面积占比对应第二背光类型。
在本实施例中，根据光亮面积占比是否小于预定占比阈值来判断显示设备所采用的背光类型。
相比于传统背光，Mini-LED背光是对应每个像素或子像素设置的，其产生的光亮的区域也会相对传统背光更加狭小。故若光亮面积占比小于预定占比阈值，则证明显示设备采用的Mini-LED背光，即其背光类型为第一背光类型，此时需要匹配对应的第一背光校正方式进行背光校正。若光亮面积占比大于预定占比阈值，则证明显示设备采用的传统背光，即其背光类型为第二背光类型，此时需要匹配传统的第二背光校正方式进行背光校正。
其中，预定占比阈值为判断显示设备所采用的背光类型的依据，由于传统背光会使用扩散片等匀光件，故理论上，传统背光下的光亮面积占比应该无限趋近于100%。而Mini-LED背光是对应每个像素或子像素设置的，故Mini-LED背光下的光亮面积占比与像素密度相关。故预定占比阈值可以取95%、98%、99%等，本公开在此不做限定。
具体的，在一些实施例中，步骤S200的具体实施方式可以参阅图5。图5是根据图3对应实施例示出的背光校正方法中步骤S200的细节描述，所述背光校正方法中，所述背光参数包括光亮密度，步骤S200可以包括以下步骤：
步骤S203，若所述光亮密度大于预定密度阈值，则所述光亮面积占比对应第一背光类型。
步骤S204，若所述光亮密度小于预定密度阈值，则所述光亮面积占比对应第二背光类型。
在本实施例中，根据光亮密度是否大于预定密度阈值来判断显示设备所采用的背光类型。
相比于传统背光，Mini-LED背光是对应每个像素或子像素设置的，其灯珠排布小而密，其产生的光斑的个数也会小而密。故若光亮密度大于预定密度阈值，则证明显示设备采用的Mini-LED背光，即其背光类型为第一背光类型，此时需要匹配对应的第一背光校正方式进行背光校正。若光亮密度小于预定密度阈值，则证明显示设备采用的传统背光，即其背光类型为第二背光类型，此时需要匹配传统的第二背光校正方式进行背光校正。其中，预定密度阈值为判断显示设备所采用的背光类型的依据，由于传统背光会使用扩散片等匀光件，故理论上，传统背光下只会产生一个均匀的光斑，光亮密度应该为1。而Mini-LED背光是对应每个像素或子像素设置的，故Mini-LED背光下的光亮密度占比与像素密度相关。在考虑到检测模块300获取的光亮图像的区域面积不会很大的前提下，预定密度阈值可以取9、10、20等，本公开在此不做限定。
具体的，在一些实施例中，步骤S200的具体实施方式可以参阅图6。图6是根据图2对应实施例示出的背光校正方法中步骤S200的细节描述，所述背光参数包括背光亮度，所述背光参数包括光亮密度，步骤S200可以包括以下步骤：
步骤S210，若所述背光亮度大于预定亮度阈值，则所述背光亮度对应第一背光类型。
步骤S220，若所述背光亮度小于预定亮度阈值，则所述背光亮度对应第二背光类型。
在本实施例中，根据背光亮度是否大于预定亮度阈值来判断显示设备所采用的背光类型。其中，获取背光亮度的方法为，通过带有光敏器件的检测模块300获取背光模块200产生的背光，光敏器件将背光的光亮转化为电信号，即可以得到背光对应的亮度。
相比于传统背光，Mini-LED背光的亮度更高。故若背光亮度大于预定亮度阈值，则证明显示设备采用的Mini-LED背光，即其背光类型为第一背光类型，此时需要匹配对应的第一背光校正方式进行背光校正。若背光亮度小于预定亮度阈值，则证明显示设备采用的传统背光，即其背光类型为第二背光类型，此时需要匹配传统的第二背光校正方式进行背光校正。
其中，预定亮度阈值为判断显示设备所采用的背光类型的依据，其值可以取500nit、550nit、600nit等，本公开在此不做限定。
具体的，在一些实施例中，步骤S200的具体实施方式可以参阅图7。图7是根据图2对应实施例示出的背光校正方法中步骤S200的细节描述，所述背光参数包括背光温度，所述背光参数包括光亮密度，步骤S200可以包括以下步骤：
步骤S230，若所述背光温度大于预定温度阈值，则所述背光温度对应第一背光类型。
步骤S240，若所述背光温度小于预定温度阈值，则所述背光温度对应第二背光类型。
在本实施例中，根据背光温度是否大于预定温度阈值来判断显示设备所采用的背光类型。
其中，获取背光温度的方法为，通过带有热敏器件的检测模块300获取背光模块200周围的环境温度，热敏器件将环境温度转化为电信号，即可以得到背光对应的背光温度。
在本公开的另一些实施例中，获取背光温度的方法还为，通过带有红外组件的检测模块300获取背光模块200发出的红外光波，红外组件通过计算红外光波的波长，即可以根据波长得到背光对应的背光温度。
相比于传统背光，Mini-LED背光发光时产生热量更多，故温度也更高。故若背光温度大于预定温度阈值，则证明显示设备采用的Mini-LED背光，即其背光类型为第一背光类型，此时需要匹配对应的第一背光校正方式进行背光校正。若背光温度小于预定温度阈值，则证明显示设备采用的传统背光，即其背光类型为第二背光类型，此时需要匹配传统的第二背光校正方式进行背光校正。
其中，预定温度阈值为判断显示设备所采用的背光类型的依据，其值可以取50度、60度等，本公开在此不做限定。
具体的，在一些实施例中，步骤S200的具体实施方式可以参阅图8。图8是根据图2对应实施例示出的背光校正方法中步骤S200的细节描述，所述背光参数包括背光温度，所述背光参数包括光亮密度，步骤S200可以包括以下步骤：
步骤S250，若所述背光亮度大于预定亮度阈值且所述背光温度大于预定亮度阈值，则所述背光参数对应第一背光类型；
步骤S260，若所述背光亮度小于预定亮度阈值且所述背光温度小于预定亮度阈值，则所述背光参数对应第二背光类型。
在本实施例中，根据背光亮度是否大于预定亮度阈值以及背光温度是否大于预定温度阈值来判断显示设备所采用的背光类型。
故若背光亮度大于预定亮度阈值且背光温度大于预定温度阈值，则证明显示设备采用的Mini-LED背光，即其背光类型为第一背光类型，此时需要匹配对应的第一背光校正方式进行背光校正。若背光亮度小于预定亮度阈值且背光温度小于预定温度阈值，则证明显示设备采用的传统背光，即其背光类型为第二背光类型，此时需要匹配传统的第二背光校正方式进行背光校正。若测得背光亮度小于预定亮度阈值同时背光温度大于预定温度阈值，或者背光亮度大于预定亮度阈值同时背光温度小于预定温度阈值，则证明数据有误，需要再次进行测量，或发送错误警报给相关维护人员，以使相关维护人员检查显示设备是否存在故障。
本实施例将背光亮度和背光温度同时作为判断显示设备背光类型的依据，可以进一步提高判断的准确率，避免出现误判，特别是在测定温度或者亮度中有一项比较接近判断阈值时，另一项就可以作为验证该结果是否准确的依据。同时，在判断结果冲突时，也可以进行多次测量对判断结果进行纠正；或者可以选取与阈值之差的绝对值更大的一个作为唯一的判断依据；抑或者发送错误警报给相关维护人员，以使相关维护人员检查显示设备是否存在故障。
例如预定温度阈值为50度，预定亮度阈值为600nit，检测的结果为背光温度49度，背光亮度800nit，则以背光亮度800nit为唯一判断依据，同时将检测结果发送至相关维护人员，以便其确定该显示设备是否出现故障。
具体的，在一些实施例中，步骤S300的具体实施方式可以参阅图9。图9是根据图2对应实施例示出的背光校正方法中步骤S300的细节描述，所述背光参数包括背光温度，所述背光参数包括光亮密度，步骤S300可以包括以下步骤：
步骤S310，若所述背光类型为第一背光类型，以第一背光校正参数进行背光校正；
步骤S320，若所述背光类型为第二背光类型，以第二背光校正参数进行背光校正；
其中，所述第一背光校正参数小于所述第二背光校正参数。
本实施例中，当背光类型为第一背光类型即Mini-LED背光时，则使用第一背光校正方式，采用较低的第一背光校正参数，使得驱动对绑点寄存器值的改变控制在一个较小的幅度，使得绑点亮度调整幅度在较小范围内，进而使得灰阶亮度调整幅度也在较小范围内，从而保证画面整体校正幅度不大，避免经过矫正后画面变得整体泛白，影响显示效果。背光类型为第二背光类型即传统背光时，则使用第二背光校正方式，采用传统的第二背光校正参数，使得驱动对绑点寄存器值的改变控制在正常的幅度，保证画面整体校正幅度正常。其中，上述的第一背光校正参数和第二背光校正参数为不同的伽马校正参数。
