具体实施方式
这里将详细地对示例性实施例进行说明，其示例表示在附图中。下面的描述涉及附图时，除非另有表示，不同附图中的相同数字表示相同或相似的要素。以下示例性实施例中所描述的实施方式并不代表与本公开相一致的所有实施方式。相反，它们仅是与如所附权利要求书中所详述的、本公开的一些方面相一致的装置和方法的例子。
图1是根据一示例性实施例示出的一种液晶显示器调整方法的流程图。如图1所示， 该液晶显示器调整方法，以具有液晶显示器的终端设备，如手机、平板电脑，作为对象进行调整，包括以下步骤S101-S103：
在步骤S101中，变更液晶显示器的源电路中的加载电压，测量液晶显示器在不同加载电压下的透过率。
在一实施例中，上述步骤S101可包括：从预设初始电压开始，按预设的步长逐步增加或减少加载电压，测量液晶显示器在增加或减少后的加载电压下的透过率，直到测量所得的透过率开始减少时为止。
上述步骤S101还可包括如下步骤A1-A2：
在步骤A1中，当测量所得的透过率开始减少时，减少当前所用步长，得到新步长。
在步骤A2中，从当前加载电压开始，按新步长逐步进行与之前增加或减少操作相反的减少或增加加载电压的操作，测量液晶显示器在减少或增加后的加载电压下的透过率，直到测量所得的透过率开始减少时为止。
举例而言，源电路的加载电压范围为4V-6V，预设初始电压为4V，预设的步长为0.3V，从4V开始，按0.3V逐步增加加载电压，测量液晶显示器在增加后的加载电压下的透过率，直到测量所得的透过率开始减少时为止；将所用步长减少到0.1V，从当前加载电压开始，按0.1V逐步减少加载电压，测量液晶显示器在减少后的加载电压下的透过率，直到测量所得的透过率开始减少时为止；将所用步长减少到0.05V，从当前加载电压开始，按0.05V逐步增加加载电压，测量液晶显示器在增加后的加载电压下的透过率，直到测量所得的透过率开始减少时为止；重复上述减少和增加加载电压的步骤，直到步长减少到预设精确度为止。
又例如，源电路的加载电压范围为4V-6V，预设初始电压为6V，预设的步长为0.3V，从6V开始，按0.3V逐步减少加载电压，测量液晶显示器在减少后的加载电压下的透过率，直到测量所得的透过率开始减少时为止；将所用步长减少到0.1V，从当前加载电压开始，按0.1V逐步增加加载电压，测量液晶显示器在增加后的加载电压下的透过率，直到测量所得的透过率开始减少时为止；将所用步长减少到0.05V，从当前加载电压开始，按0.05V逐步减少加载电压，测量液晶显示器在减少后的加载电压下的透过率，直到测量所得的透过率开始减少时为止；重复上述减少和增加加载电压的步骤，直到步长减少到预设精确度为止。
在步骤S102中，根据加载电压与透过率间对应关系，确定液晶显示器的最大透过率所对应的加载电压。
在一实施例中，上述步骤S102可包括：根据加载电压与透过率间对应关系，确定出临界加载电压，将临界加载电压作为最大透过率所对应的加载电压。
其中，当加载电压大于或小于临界加载电压时，液晶显示器的透过率开始减少。
举例而言，如图2所示，临界加载电压为5V，透过率在临界加载电压时最大，加载电压大于或小于临界加载电压时，液晶显示器的透过率开始减少。各个液晶显示器的临界 加载电压不相同，因此通过变更每个液晶显示器的源电路中的加载电压来查找到每个液晶显示器的临界加载电压。
在步骤S103中，根据最大透过率所对应的加载电压确定源电路的工作电压，将源电路中加载电压调整为工作电压。
举例而言，以最大透过率所对应的加载电压为中心，在预设范围内确定源电路的工作电压，将源电路中加载电压调整为该工作电压。例如，最大透过率所对应的加载电压为5.2V，以最大透过率所对应的加载电压5.2V为中心，在预设范围4.8V-5.6V内确定源电路的工作电压为5V，将源电路中加载电压调整为5V。
本公开的实施例提供的技术方案可以包括以下有益效果：通过将源电路的工作电压调整到液晶显示器最大透射率对应的电压，来增加液晶显示器的透射率，进而增加液晶显示器的亮度，如此，能够在不改变液晶显示器结构的情况下，增加液晶显示器的亮度。
图3是根据一示例性实施例示出的另一种液晶显示器调整方法的流程图。如图3所示，该液晶显示器调整方法，以具有液晶显示器的终端设备，如手机、平板电脑，作为对象进行调整，包括以下步骤：
在步骤S301中，变更液晶显示器的源电路中的加载电压，测量液晶显示器在不同加载电压下的透过率。
在步骤S302中，根据加载电压与透过率间对应关系，确定液晶显示器的最大透过率所对应的加载电压。
在步骤S303中，根据最大透过率所对应的加载电压确定源电路的工作电压，将源电路中加载电压调整为工作电压。
上述步骤S301-S303的示例性说明，参见步骤S101-S103中示例性说明，在此不再赘述。
在步骤S304中，在保持源电路的加载电压为确定的工作电压的情况下，将液晶显示器的色温调整到预设色温值。
举例而言，预设色温值为6500K，在保持源电路的加载电压为确定的工作电压的情况下，调整红绿蓝RGB三个颜色的电压，并逐步测量液晶显示器的色温，直至色温调整到6500K为止。
在步骤S305中，在保持源电路的加载电压为确定的工作电压，且色温为调整到的预设色温值的情况下，将液晶显示器的伽马值调整到预设伽马值。
举例而言，预设伽马值为2.2，在保持源电路的加载电压为确定的工作电压，且色温为调整到的预设色温值的情况下，调整各个灰阶电压，使得伽马值为2.2。
本公开的实施例提供的技术方案可以包括以下有益效果：在保证液晶显示器亮度的前提下，能够使得图像显示效果更优。

在步骤S403中，从当前加载电压开始，按新步长逐步进行与之前增加或减少操作相反的减少或增加加载电压的操作，测量液晶显示器在减少或增加后的加载电压下的透过率，直到测量所得的透过率开始减少时为止。
在步骤S404中，重复上述步骤S402和步骤S403，直到步长减少到预设精确度为止。
在步骤S405中，在保持源电路的加载电压为确定的工作电压的情况下，将液晶显示器的色温调整到预设色温值。
