Description

液晶显示面板的暗态电压调试方法、装置以及存储介质 技术领域
本申请涉及显示技术领域，具体涉及一种液晶显示面板的暗态电压调试方法、装置以及存储介质。
 背景技术
液晶显示面板因具有厚度薄、亮度高、辐射小等优点，已被广泛应用在诸如手机、智能监控器、液晶电视、个人电脑等显示产品上。在液晶显示面板工作过程中，为了避免液晶分子的转向一直固定在一个方向造成特性破坏，液晶显示面板内的显示电压分成了正极性电压和负极性电压。其中，当显示电极的电压高于公共电极电压时，就称之为正极性电压；当显示电极的电压低于公共电极的电压时，就称之为负极性电压。液晶显示面板中的每一灰阶均对应一正极性电压与负极性电压。
 技术问题
通常液晶显示面板的各灰阶正负极性电压可根据VT曲线（穿透率曲线）或目标亮度曲线等进行调整确定，但是，由于暗态电压取值范围较广，使得暗态电压差值（正极性电压与负极性电压之间的差值）较难确定，进而影响到液晶显示面板的对比度。

下面将结合本申请实施例中的附图，对本申请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申请一部分实施例，而不是全部的实施例。基于本申请中的实施例，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。
在本申请的描述中，需要理解的是，术语“第一”和“第二”仅用于描述目的，而不能理解为指示或暗示相对重要性或者隐含指明所指示的技术特征的数量。由此，限定有“第一”和“第二”等的特征可以明示或者隐含地包括一个或者更多个所述特征，因此不能理解为对本申请的限制。
本申请实施例提供的液晶显示面板的暗态电压调试方法通过获取多个初始暗态电压差值。并基于所述多个初始暗态电压差值，得到每一初始暗态电压差值对应的对比度值；然后，获取多个初始暗态电压差值中的基准暗态电压差值，并基于该基准暗态电压差值，得到每一初始暗态电压差值对应的对比度变化量；最后，根据每一初始暗态电压差值对应的对比度变化量，确定液晶显示面板的暗态电压差值。该方法可以通过每一初始暗态电压差值与相应对比度变化量之间的关系确定液晶显示面板的暗态电压差值，从而规范液晶显示面板的暗态电压差值，提高液晶显示面板的对比度。
以下进行详细介绍。
请参阅图1，图1是本申请实施例提供的液晶显示面板的暗态电压调试方法的流程示意图。如图1所示，该液晶显示面板的暗态电压调试方法包括以下步骤：
101、获取多个初始暗态电压差值。
其中，暗态电压包括第一电压和第二电压。第一电压高于公共电极电压。第二电压低于公共电极电压。暗态电压差值等于第一电压与第二电压之间的差值。通过反向调整第一电压与第二电压，可以获取多个初始暗态电压差值。需要说明的是，暗态电压差值为零时的暗态电压可以是液晶显示面板的初始伽马电压中的最小电压；暗态电压差值为零时的暗态电压也可以是使得液晶显示面板亮度最低时的电压。
具体的，在一些实施例中，请参阅图2，步骤101包括：
1011、获取调整参数。
其中，调整参数包括第一调整参数以及第二调整参数。第一调整参数与第二调整参数可根据实际需求进行设定。在一些实施例中，第一调整参数与第二调整参数相同。可以理解的是，理想状况下，第一电压与第二电压相较于公共电极电压对称，此时液晶显示面板分别在第一电压与第二电压驱动下的亮度相等，能够减小闪烁。但是，在实际生产过程中，由于液晶显示面板中的阻抗或影像残留等因素，第一电压与第二电压相较于公共电极电压不对称，则第一调整参数与第二调整参数可以不相同。
1012、基于所述调整参数调整所述暗态电压，以获取多个所述初始暗态电压差值。
具体的，基于第一调整参数调整第一电压；基于第二调整参数调整第二电压；从而改变第一电压与第二电压之间的差值，以获取多个初始暗态电压差值。
102、基于所述多个初始暗态电压差值，得到每一所述初始暗态电压差值对应的对比度值。
具体的，在一些实施例中，请参阅图3，步骤102包括：
1021、获取每一所述初始暗态电压差值对应的暗态电压。
如上所述，暗态电压包括第一电压与第二电压，通过调整第一电压与第二电压，从而得到多个初始暗态电压差值。则获取每一初始暗态电压差值对应的暗态电压，即获取每一初始暗态电压差值对应的第一电压以及第二电压。
1022、基于每一所述初始暗态电压差值对应的暗态电压，得到每一所述初始暗态电压差值对应的对比度值。
其中，对比度是液晶显示面板上同一点最亮时的亮度（亮态亮度）与最暗时的亮度（暗态亮度）的比值，高的对比度意味着相对较高的亮度和呈现颜色的艳丽程度。需要说明的是，当利用暗态电压驱动液晶显示面板时，液晶显示面板的发光亮度即为暗态亮度。当利用亮态电压（最大驱动电压）驱动液晶显示面板时，液晶显示面板的发光亮度即为亮态亮度。
具体的，利用每一初始暗态电压差值对应的暗态电压驱动液晶显示面板，使得液晶显示面板发光。然后利用光学传感器测量液晶显示面板中心区域的暗态亮度，以得到多个暗态亮度值。
此外，可通过目标亮度曲线对初始伽马电压进行调整以获取液晶显示面板的亮态电压。利用亮态电压驱动液晶显示面板，以使液晶显示面板发光。然后，利用光学传感器测量液晶显示面板中心区域的亮态亮度，以得到亮态亮度值。
进而通过亮态亮度值与暗态亮度值的比值得到每一初始暗态电压差值对应的对比度值。
需要说明的是，由于液晶显示面板采用的对比度规格通常是正视角对比度规格，因此，光学传感器垂直液晶显示面板中心区域放置，以采集液晶显示面板的正视角暗态亮度以及正视角亮态亮度，但不限于此。
103、获取所述多个初始暗态电压差值中的基准暗态电压差值，并基于所述基准暗态电压差值，得到每一所述初始暗态电压差值对应的对比度变化量。
其中，基准暗态电压差值可以根据实际需求进行设置，本申请对此不作限定。在一些实施例中，可以选取暗态电压差值为零时的初始暗态电压差值为基准暗态电压差值。当暗态电压差值为零时的初始暗态电压使得液晶显示面板亮度最低时，在亮态亮度一致的情况下，液晶显示面板的对比度最好。因此，以暗态电压差值为零时的初始暗态电压差值为基准暗态电压差值，可以直观的体现每一初始暗态电压差值对应的对比度值的下降幅度。
具体的，请参阅图4，步骤103包括：
1031、获取所述基准暗态电压差值对应的对比度值以及每一所述初始暗态电压差值对应的对比度值。
具体的，选定基准暗态电压差值后，获取该基准电压差值对应的对比度值；同时获取每一初始暗态电压差值对应的对比度值，以便后续步骤的使用。
1032、基于所述基准暗态电压差值对应的对比度值以及每一所述初始暗态电压差值对应的对比度值，计算每一所述初始暗态电压差值对应的对比度变化量。
具体的，在一些实施例中，每一初始暗态电压差值对应的对比度变化量可以采用方法A进行运算：首先，计算每一所述初始暗态电压差值对应的对比度值与所述基准暗态电压差值对应的对比度值之间的对比度差值；然后，计算每一初始暗态电压差值对应的对比度差值与基准暗态电压差值对应的对比度值之间的比值，得到每一初始暗态电压差值对应的对比度变化量。
需要说明的是，第方法A中，也可以计算所述基准暗态电压差值对应的对比度值与每一所述初始暗态电压差值对应的对比度值之间的对比度差值，本申请对此不作限定。
该方法计算得到的对比度变化量体现了每一初始暗态电压差值对应的对比度值相较于基准电压差值对应的对比度值的变化量，从而体现出当暗态电压差值变化时，液晶显示面板的对比度变化趋势。
在一些实施例中，每一初始暗态电压差值对应的对比度变化量也可以采用方法B进行运算：计算每一初始暗态电压差值对应的对比度值与基准暗态电压差值对应的对比度值之间的比值，得到每一初始暗态电压差值对应的对比度变化量。
需要说明的是，在方法B中，也可以计算基准暗态电压差值对应的对比度值与每一初始暗态电压差值对应的对比度值之间的比值，本申请对此不作限定。
该方法通过每一初始暗态电压差值对应的对比度值与基准电压差值对应的对比度值之间的比值关系，直接体现出当暗态电压差值变化时，液晶显示面板的对比度变化趋势，简化了计算过程，提高了工作效率。
需要说明的是，以上对每一初始暗态电压差值对应的对比度变化量的计算方法仅为对本申请的技术方案进行说明，但不能理解为对本申请的限定。对于能够体现每一初始暗态电压差值对应的对比度值相较于基准电压差值对应的对比度值的变化量的计算方法，均可用于实现本申请的技术方案。
104、根据每一所述初始暗态电压差值对应的对比度变化量，确定所述液晶显示面板的暗态电压差值。
可以理解的是，在通过步骤103得到每一初始暗态电压差值对应的对比度变化量后，可根据对比度变化量与初始暗态电压差值之间的关系，确定液晶显示面板可以设定的暗态电压差值。
具体的，请参阅图5，步骤104包括：
1041、获取基准对比度变化量。
基准对比度变化量可根据液晶显示面板的规格要求进行设置，本申请对此不作限定。可以理解的是，衡量液晶显示面板的参数众多，包括对比度、影像残留或画面串扰等显示参数。通常暗态电压差值为零时对应的液晶显示面板的对比度较好，但是为了改善影像残留等显示问题，需要对暗态电压差值做一定的增大。因此，在实际生产过程中，若在液晶显示面板的规格参数中对比度规格较高，则基准对比度变化量可在较小变化范围内进行取值；若在液晶显示面板的规格参数中对于影像残留等显示效果的要求较高，则基准对比度变化量可在满足对比度规格的较大变化范围内进行取值，进而在最大程度改善其他显示问题的同时，避免对比度参数不合格。
1042、当所述初始暗态电压差值对应的对比度变化量与所述基准对比度变化量之间满足预设条件时，确定所述初始暗态电压差值为所述液晶显示面板的暗态电压差值。
具体的，预设条件的设定可根据初始暗态电压差值对应的对比度变化量的计算方法以及基准对比度变化量的设定进行设置。
比如，当以对比度值最高时对应的初始暗态电压差值作为基准暗态电压差值，在基准对比度变化量为X时，可设置预设条件为当初始暗态电压差值对应的对比度变化量小于X时，对应的初始暗态电压差值均可作为液晶显示面板的暗态电压差值。

具体的，通过对暗态电压进行调整，获取多个初始暗态电压差值后，利用每一初始暗态电压差值对应的暗态电压驱动液晶显示面板，使得液晶显示面板发光，进而采集每一初始暗态电压差值对应的暗态亮度，具体步骤可参阅以上实施例，在此不再赘述。

图6C是本申请实施例提供的初始暗态电压差值与相应对比度变化量的关系曲线。其中，图6C中的横坐标为初始暗态电压差值，单位是伏特（V）；纵坐标为对比度变化量。该关系曲线中的对比度变化量采用以上实施例中所述的方法A进行运算，在此不再赘述。其中，选取的基准暗态电压差值为零，其在图6B中对应的对比度值作为基准对比度，进而通过方法A得到每一初始暗态电压差值对应的对比度变化量。
进一步的，基于图6C中对比度变化量与初始暗态电压差值之间的关系，可设定一基准对比度变化量，并根据该基准对比度变化量确定液晶显示面板的暗态电压差值。具体的，在一些实施例中，可设定基准对比度变化量为0%，即在对比度值最高的范围内设定暗态电压差值，如图6C所示，初始暗态电压差值在1V范围内均满足该预设条件；在另一些实施例中，综合考虑液晶显示面板的对比度以及影像残留等多方面显示参数时，可设定基准对比度变化量为-5%，相应对比度变化量大于-5%的初始暗态电压差值均满足要求，即初始暗态电压差值在2.5V范围内均满足该预设条件，使得在改善其他显示问题的同时，避免达不到对比度的规格要求。
