具体实施方式
下面结合附图，对本发明的实施例进行描述。
发明人在研究中发现，目前导致液晶屏幕在低温情况下出现闪屏的原因包括：由于整个温度轴都使用一套帧频，使得所使用的帧频，高于液晶屏幕在低温情况下正常显示所需的帧频，进而导致液晶屏幕在低温情况下会出现致闪屏。
图1为本申请实施例提供的液晶屏幕的帧频控制方法的应用场景示意图，包括液晶屏幕和处理器，其中，液晶屏幕包括集成电路。其中，处理器用于控制液晶屏幕的集成电路。
图2为本申请实施例提供的一种液晶屏幕的帧频控制方法，本实施例的执行主体为处理器，可以包括以下步骤：
S201、获取液晶屏幕的集成电路检测的温度。
在本实施例中，液晶屏幕的集成电路(Integrated circuit，IC)具有检测液晶屏幕的温度的功能，即检测液晶屏幕所处环境的温度。
在本步骤中，获取液晶屏幕IC的温度。在实际中，本步骤的获取可以为实时获取。
由于可以获取到液晶屏幕的温度，因此，可以判断液晶屏幕的温度的变化情况。其中，温度变化可以包括温度升高和温度降低。
S202、判断液晶屏幕的温度是否从预设的多个温度范围中的一个温度范围变化到另一个温度范围，如果是，则执行S203，如果否，则执行S201。
在本实施例中，预设的多个温度范围可以依据预设的多个温度节点确定，其中，该多个温度节点需要根据液晶屏幕的温度特性进行确定。本实施例不对温度节点的具体内容作限定。
例如，在本实施例中，预设的三个温度节点分别为-25℃、0℃和50℃。其中，利用该三个温度节点确定多个温度范围的方式可以包括：将该三个温度节点将温度轴分割成的温度范围，作为多个温度范围，分别是低于-25℃的温度范围、从-25℃到0℃的温度范围，从0℃到50℃的温度范围，以及高于50℃的温度范围。
在本步骤中，判断液晶屏幕的温度是否从多个温度范围变化到另一个温度范围，其中，另一个温度范围是多个温度范围中的哪个温度范围，本实施例不作限定。
在实际中，由于温度变化包括温度上升和温度下降两种情况下，因此，在实际中，本步骤可以具体判断液晶屏幕的温度是否从多个温度范围中的一个温度范围降低到另一个温度范围，或者，判断液晶屏幕的温度是否从多个温度范围中的一个温度范围上升到另一个温度范围，只要判断出这两种情况中的任意一种，则表示液晶屏幕的温度从预设的多个温度范围中的一个温度范围变化到另一个温度范围。
上述S201～S202的目的是：检测液晶屏幕的温度是否从预设的多个温度范围中的一个温度范围变化到另一个温度范围。
S203、依据多个温度范围与帧频间的预设关系，确定液晶屏幕的温度所属的温度范围对应的帧频，得到目标帧频。
在本实施例中，在设定出多个温度范围的情况下，还为每个温度范围设定帧频，从而，得到多个温度范围与对应的帧频之间形成的对应关系。其中，为不同的温度范围设定的帧频不同，并且，为每个温度范围设定的帧频是符合液晶屏幕在温度范围能够正常显示的帧频。
在本实施例中，为每个温度范围设定的帧频的具体取值，需要根据实际情况，本 实施例不对每个温度范围对应的帧频的具体取值作限定。
在本步骤中，在判断到液晶屏幕的温度从一个温度范围变化到另一个温度范围的情况下，从温度范围与帧频间的对应关系中，确定液晶屏幕的温度所属的温度范围对应的帧频，为了描述方便，将液晶屏幕的温度所属的温度范围对应的帧频，称为目标帧频。
S204、控制液晶屏幕的集成电路的帧频调整为目标帧频。
在确定出目标帧频的情况下，控制液晶屏幕的集成电路的帧频调整为目标帧频。
在实际中，如果将预设的多个温度节点将温度轴分割成温度范围，作为多个温度范围，在液晶屏幕的温度从一个温度范围变化到另一个温度范围的情况下，以液晶屏幕的温度从第一温度范围变化到第二温度范围进行描述。由于液晶屏幕的温度可能不稳定，出现在“第二温度范围”的临界温度上下浮动，使得液晶屏幕的温度从第一温度范围变化到第二温度范围，以及从第二温度范围变化到第一温度范围的过程频繁切换，使得针对液晶屏幕的温度确定出的目标帧频在第一温度范围和第二温度范围分别对应的帧频之间频繁切换，使得控制液晶屏幕的集成电路的帧频发生频繁的改变，导致液晶屏幕出现闪屏的问题。
例如，假设设定三个温度节点分别为-10℃、0℃和10℃。如果将该三个温度节点将温度轴分割成的温度范围，作为多个温度范围，则得到四个温度范围，分别是低于-10℃的温度范围、从-10℃到0℃的温度范围，从0℃到10℃的温度范围，以及高于10℃的温度范围。假设高于10℃的温度范围对应的帧频为FRD，0℃到10℃的温度范围对应的帧频为FRC。
则在液晶屏幕的温度降低到10℃的情况下，需要控制集成电路的帧频从FRD调整为FRC，在液晶屏幕的温度降低为10℃还不稳定的情况下，可能出现液晶屏幕的温度从10℃上升到11℃，则需要控制集成电路的帧频从FRC调整为FRD，如果液晶屏幕的温度再从11℃降低到10℃的情况下，需要控制集成电路的帧频从FRD调整为FRC，如果该过程反复重复，则液晶屏幕会出现闪屏的问题。
为了解决由于控制液晶屏幕的集成电路的帧频频繁改变，导致的液晶屏幕出现闪屏的问题，本申请实施例，由于温度变化可以包括温度降低和温度升高，因此，可以对于温度降低和温度升高这两种情况，分别基于预设的多个温度节点，确定出的用于构成多个温度范围的温度节点不同。为了描述方便，对于温度降低的情况，将依据预设的温度节点，确定出的用于构成多个温度范围的温度节点，称为第一温度节点。对于温度升高的情况，将依据预设的温度节点，确定出的用于构成多个温度范围的节点，称为第二温度节点。其中，多个第一温度点与多个第二温度点不同，并且，第二温度节点序列与第二温度节点序列中，相同排序位置下的第二温度节点与第一温度节点间的差值属于预设范围。其中，第一温度节点序列是对多个第一温度节点按照预设的先后顺序排序得到，第二温度节点序列是对多个第二温度节点按照该先后顺序排序得到。
需要说明的是，第二温度节点序列与第一温度节点序列中，不同排序位置下的第二温度节点与第一温度节点的差值可以不同，只要都属于预设范围即可。即本申请实施例的目的主要是将第二温度节点序列与第一温度节点序列中，相同排序位置下的第二温度节点与第一温度节点错开。
在本实施例中，为了描述方便，将由多个第一温度节点将温度轴分割得到的多个温度范围，称为多个第一温度范围。将由多个第二温度节点将温度轴分割得到的多个温度范围，称为多个第二温度范围。
需要说明的是，在本实施例中，按照先后顺序排序后的多个第一温度范围与按照该先后顺序排序后的多个第二温度范围中，相同排序位置下的温度范围对应的帧频相同。
具体的，检测液晶屏幕的温度是否从预设的多个温度范围中的一个温度范围降低到另一个温度范围的具体实现方式可以包括：检测液晶屏幕的温度是否从预设的多个第一温度范围中的一个温度范围降低到另一个温度范围的最大温度值。
检测液晶屏幕的温度是否从预设的多个温度范围中的一个温度范围上升到另一个温度范围的具体实现方式可以包括：检测液晶屏幕的温度是否从预设的多个第二温度范围中的一个温度范围上升到另一个温度范围的最小温度值。
例如，还以预设的三个温度节点分别为-10℃、0℃和10℃为例，假设三个第 一温度节点的取值为-10℃、0℃和10℃，三个第二温度节点的取值为-5℃、5℃和15℃，如图3所示。
在图3中，横轴表示温度，纵轴表示帧频，TA、TB和TC表示预设的三个温度节点，其中，TA的取值为-10℃、TB的取值为0℃，以及TC的取值为10℃。其中，FRA、FRB、FRC和FRD分别表示不同的帧频取值。其中，上升的箭头表示液晶屏幕的温度上升，下降的箭头表示液晶屏幕的温度降低。
从图3中可以看出，在液晶屏幕的温度降低到10℃的情况下，需要控制集成电路的帧频从FRD调整为FRC，液晶屏幕的温度从10℃上升到11℃，此时，还未到达15℃，因此，无需控制集成电路的帧频从FRC调整为FRD，即集成电路的帧频还是FRC。如果液晶屏幕的温度再从11℃降低到10℃的情况下，控制集成电路的帧频为FRC，即集成电路的帧频还是FRC，如果该过程反复重复，集成控制电路的帧频不会频繁变化，进而，液晶屏幕不会出现闪屏的问题。
在实际中，在低温下，液晶屏幕的响应速度很慢，即液晶屏幕要达到预设的灰阶电压，用时会很长。具体的，在低温下开机时，液晶屏幕的响应速度跟不上，使得液晶屏幕在短时间内转不到预定的角度，因此，液晶屏幕会出现显示偏淡，无显等问题。
发明人在研究中发现，采用过驱动可以解决该问题。其中，过驱动指：在液晶屏幕的预设的灰阶电压范围内，短时间内给液晶屏幕的两端增加一个过电压(比预设的灰阶电压稍高)，让液晶屏幕快速地达到预设的角度，从而，可以更快更清晰的显示内容。
因此，在本申请实施例中，在检测液晶屏幕的温度是否从预设的多个温度范围中的一个温度范围变化到另一个温度范围之前，对液晶屏幕的帧频控制方法还可以包括：
在接收到开机指令并且液晶屏幕的温度低于预设温度的情况下，控制集成电路增加提供给液晶屏幕的VOP电压。
可选的，由于BootLoader程序在设备开机的起始阶段有效，且时间相对很短，因此，可以利用该BootLoader程序进行过电压驱动。具体的，提高BootLoader的VOP电压，液晶屏幕响应之后，施加给集成电路的VOP电压为预设的VOP电压，即开机 时VOP电压比液晶屏幕正常显示后的预设VOP电压高，使得液晶分子快速转到预定角度，从而使屏幕能够正常显示。即通过提高预设的Bootloader程序的VOP电压，控制集成电路提供给液晶屏幕的VOP电压高于预设的VOP电压。
其中，分别在正常VOP(预设的VOP电压)与过驱动VOP(过驱动VOP电压)下，液晶角度(液晶屏幕达到的角度)的变化情况，如图4所示。从图4中可以看出在Bootloader工作的时间段，给液晶屏幕提供的VOP电压为过驱动VOP电压，液晶屏幕的角度变化时间，明显低于给液晶屏幕提供的VOP电压为正常VOP下的时间。
