 本发明的实施方式
下面将结合本发明实施例中的附图，对本发明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发明一部分实施例，而不是全部的实施例。基于本发明中的实施例，本领域技术人员在没有作出创造性劳动前提下所获得的所有其他实施例，都属于本申请保护的范围。
一种调光方法，应用于显示装置，所述调光方法包括：获取调光指令；根据所述调光指令，将所述显示装置的显示区域进行分区，形成多个调光区域；在每一所述调光区域对应设置一调光信号；其中每一调光区域对应设置一调光信号的第一电平占比相互错开。
如图1所示，在该图1中，该图1为本申请实施例提供的调光方法的流程示意图。在本申请实施例中，该调光方法应用于显示装置，所述显示装置可以为智能手机、平板电脑、仪表盘或者电脑等显示装置，所述调光方法的具体流程如下：
S10，获取调光指令；
具体的，该调光指令为本申请实施例所提供的调光方法在实施该调光方法之前，在预设条件下生成的调光指令，例如，在该步骤S10之前，请参见图2，该本申请实施例所提供的调光方法的另一流程示意图，还包括：
S40，接收所述显示区域中输入的调光信号和时钟信号。
进一步的，该调光信号具体是指显示装置中发光元件输出PWM信号，且该PWM信号的高/低电平来开启/关断驱动电路向负载输出驱动电压或驱动电流，且该PWM信号为脉冲信号。
进一步的，该时钟信号具体是指该显示装置中由外部时序逻辑控制器所控制的该显示装置的时序信号，该时序信号一般为脉冲信号。
具体的，该调光信号的周期一般与时钟信号的周期相同，且在时钟信号的高电平对应的时间内，包括该调光信号的高电平对应的时间与该调光信号对应的低电平的时间的总和。
S50，计算所述调光信号的有效宽度与所述时钟信号的有效宽度的比值。
进一步的，该有效宽度是指信号对应的波形中的脉冲宽度（pulse width），又名工作周期（Duty Cycle）；即该信号对应的电流或者电压随时间有规律变化的时间宽度，一般情况下，该信号对应的波形是方波，三角波，锯齿波，正弦函数波等等，这些波形变化都是有一定规律的，尤其是对于方波型的信号波形中，该脉冲宽度具体指占空比，即在一段连续工作时间内脉冲占用的时间与总时间的比值。
具体的，本申请实施例中提供的调光信号与时钟信号为方波型的脉冲函数。譬如，当调光信号的脉冲宽度1μs，调光信号的周期4μs时，则该调光信号对应的有效宽度为1/4=0.25；当周期信号的脉冲宽度为4μs时，该周期信号的周期为5μs时，该周期信号对应的有效宽度为4/5=0.8。进一步的，可以根据所述调光信号的有效宽度与所述时钟信号的有效宽度的比值，即0.25/0.8=0.3125。
S60，当所述比值小于预设阈值时，生成所述调光指令。
在本申请实施例中，鉴于现有技术的显示装置，尤其是液晶显示面板内部器件受强光照射时，会造成像素单元内的存储电容发生改变，导致显示面板内液晶充电电压与驱动晶体管的阈值电压发生偏移，本申请实施例可测试显示装置在强光照射时，测量出对应的所述调光信号的有效宽度与所述时钟信号的有效宽度，并计算其对应的值作为本申请实施例所提供的预设阈值。譬如，经检测，当该预设阈值设置为1时，而本申请实施例对应的比值为0.3125，则证明该显示装置中的液晶充电电压与驱动晶体管的阈值电压发生偏移，需要生成所述调光指令，以完成后续调光步骤。
S20，根据所述调光指令，将所述显示面板的显示区域进行分区，形成多个调光区域；具体的，请参见图3，该图3为本申请实施例提供的调光方法的步骤S20的流程方法示意图，该步骤S20具体包括：
S201，确定所述显示装置中数据线的数量，并根据所述数量确定区域数量。
进一步的，请参见图5，该图5为本申请实施例提供的显示面板的结构示意图，具体的，在该显示面板中，该显示面板的显示区域为该显示面板的有效发光区域，且该显示区域的横向边缘设置有多条数据线DATA，该显示区域的纵向设置有多条扫描线SCAN，因此，确定该显示面板中数据线DATA的数量，并根据所述数量确定区域数量，在该图5中，可分区为area1、area2、……area n-1、area n等多个区域。
譬如，当确定该数据线的数量为10条时，本申请实施例所确定的区域数量，并且该区域数量与该数据线DATA的数量有关，且该优选的，该区域数量可设置与本数据线DATA的数量对应，例如，为5个、10个或者20个。

进一步的，请参见图4，该图4为本申请实施例提供的调光方法的步骤S203的流程方法示意图，该步骤S203具体可包括：
S2031，根据所述第一长度与所述区域数量，计算第一单位长度；
譬如，当确定所述第一长度为10cm时，该区域数量为20个时，可计算出其第一长度上对应的分区数量为20对应的公约数，例如5个，可采取对该显示区域进行均等分的形式，计算出该第一单位长度为10/5=2cm，即该每个调光区域的一个边长为2cm。
S2032，根据所述第一单位长度，将所述显示区域沿栅极线分割成与所述区域数量相等的多个区域。
譬如，当确定该第一单位长度为2cm时，可以对该显示区域按照第一长度L1进行均等分，以将所述显示区域沿栅极线分割成与所述区域数量相等的多个区域。

进一步的，具体分割方式请参见图6，该图6为本申请实施例提供的显示面板的另一种结构示意图，根据所述第二单位长度L2，将所述显示区域沿数据线DATA分割成与所述区域数量相等的多个区域，以对所述显示区域进行网格化分区，在该实施例中，并结合扫描线SCAN的数量，当第一单位长度为2cm，第一单位长度为2cm，由此可计算出该调光区域对应的单位区域的长为2cm，宽为2cm，并可对该显示区域进行网格化分区，以对所述显示区域进行分区，沿着扫描线SCAN方向，该显示面板可分为area11、area12、……area 1n-1、area1n，沿着数据线DATA方向，该显示面板可划分为area11、area21、……area（n-1）1、area n1。

譬如，当该区域数量设置为n个时，即该每个所述调光区域均会对应一个调光信号的波形，且该每个调光信号的波形的脉冲起始时间不同。当该脉冲的起始时间不同时，避免了现有技术中，显示面板的同一栅极线上的脉冲波形出现较高的占空比，进而沿栅极线方向的出现水平条块现象，造成画面显示不良的现象。
在本实施例中，控制对应调光区域中的调光信号由外部时序逻辑控制器控制。
由上述可知，本实施例提供的调光方法，应用于显示装置，所述调光方法包括：获取调光指令，并根据所述调光指令，将所述显示面板的显示区域进行分区，形成多个调光区域，在每一所述调光区域对应设置一调光信号；其中每一调光区域对应设置一调光信号的第一电平占比相互错开，本申请通过将显示区域进行分区，使得同一栅极线划分为不同的调光区域，并保证每个调光区域中调光信号的脉冲起始时间不同，从而避免同一栅极线上出现较高占空比，以改善画面显示不良的现象。
根据上述实施例所描述的方法，本实施例将从调光装置的角度进一步进行描述，该调光装置具体可作为独立的实体来实现。
本实施例提供一种调光装置及系统。
请参阅图8，为本申请实施例所提供的调光装置，该调光装置具体可以集成在服务器或终端等显示装置中。
其中，显示装置获取调光指令，并根据所述调光指令，将所述显示面板的显示区域进行分区，形成多个调光区域，在每一所述调光区域对应设置一调光信号，其中每一调光区域对应设置一调光信号的第一电平占比相互错开，以对所述显示面板进行调光。
请参阅图8，该调光装置可以包括：获取模块10、分区模块20、配置模块30。
（1）获取模块10
获取模块10，用于获取调光指令。
在本实施例中，该调光指令为本申请实施例所提供的调光方法在实施该调光方法之前，在预设条件下生成的调光指令。
在本实施例中，该调光装置还包括生成模块50，请参见图9，该图9为本申请实施例所提供的另一种调光装置，包括生成模块40，具体用于：
（01）.接收所述显示区域中输入的调光信号和时钟信号。
进一步的，该调光信号具体是指显示装置中发光元件输出PWM信号，且该PWM信号的高/低电平来开启/关断驱动电路向负载输出驱动电压或驱动电流，且该PWM信号为脉冲信号。
进一步的，该时钟信号具体是指该显示装置中由外部时序逻辑控制器所控制的该显示装置的时序信号，该时序信号一般为脉冲信号。
具体的，该调光信号的周期一般与时钟信号的周期相同，且在时钟信号的高电平对应的时间内，包括该调光信号的高电平对应的时间与该调光信号对应的低电平的时间的总和。
（02）.计算所述调光信号的有效宽度与所述时钟信号的有效宽度的比值。
进一步的，该有效宽度是指信号对应的波形中的脉冲宽度（pulse width），又名工作周期（Duty Cycle）；即该信号对应的电流或者电压随时间有规律变化的时间宽度，一般情况下，该信号对应的波形是方波，三角波，锯齿波，正弦函数波等等，这些波形变化都是有一定规律的，尤其是对于方波型的信号波形中，该脉冲宽度具体指占空比，即在一段连续工作时间内脉冲占用的时间与总时间的比值。
具体的，本申请实施例中提供的调光信号与时钟信号为方波型的脉冲函数。譬如，当调光信号的脉冲宽度1μs，调光信号的周期4μs时，则该调光信号对应的有效宽度为1/4=0.25；当周期信号的脉冲宽度为4μs时，该周期信号的周期为5μs时，该周期信号对应的有效宽度为4/5=0.8。进一步的，可以根据所述调光信号的有效宽度与所述时钟信号的有效宽度的比值，即0.25/0.8=0.3125。
（03）.当所述比值小于预设阈值时，生成所述调光指令。
在本申请实施例中，鉴于现有技术的显示装置，尤其是液晶显示面板内部器件受强光照射时，会造成像素单元内的存储电容发生改变，导致显示面板内液晶充电电压与驱动晶体管的阈值电压发生偏移，本申请实施例可测试显示装置在强光照射时，测量出对应的所述调光信号的有效宽度与所述时钟信号的有效宽度，并计算其对应的值作为本申请实施例所提供的预设阈值。譬如，经检测，当该预设阈值设置为1时，而本申请实施例对应的比值为0.3125，则证明该显示装置中的液晶充电电压与驱动晶体管的阈值电压发生偏移，需要生成所述调光指令，以完成后续调光步骤。
