 本发明的实施方式
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，所描述的实施例仅是本申请的一部分实施例，而不是全部的实施例。基于本申请中的实施例，本领域普通技术人员在没有做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。
如图1所示，本申请显示驱动方法第一实施例包括：
S11：获取待显示图像。
其中，可以将该待显示图像缓存在存储器等存储介质中，以便后续处理。该待显示图像可以是一帧显示数据，也可以是多帧显示数据，此处不做具体限定。
S12：判断待显示图像相对于前一帧显示图像的变化程度是否超过预设范围。
若判断结果为是，则执行步骤S13。
其中，该预设范围是预先设置的判定显示内容为动态画面的显示图像变化范围，当待显示图像相对于前一帧显示图像的变化程度超过预设范围时，即表示相对于前一帧显示图像，该待显示图像是动态画面。该预设范围可以是像素值变化大于预设阈值的像素点的数量范围，也可以是颜色变化或亮度变化大于预设变化值的像素点或特征点的数量范围等，该变化程度其可以针对整个显示图像，也可以针对某些区域或某些特征点，此处不做具体限定。
可选地，如图2所示，步骤S12具体可以包括：
S121：获取待显示图像至少部分区域每个像素点的像素值与前一帧显示图像中同一区域的对应像素点的像素值的差值。
其中，该至少部分区域可以是显示图像的某些区域，区域个数可以是一个，也可以是多个，当然，该至少部分区域也可以是显示图像的整个显示区域，此处不做具体限定。
S122：统计该差值大于预设像素阈值的像素点数量。
其中，该预设像素阈值是预先设置的判定待显示图像为动态画面时，像素点的像素值相对于前一帧显示图像对应位置的像素点像素值的变化的最小幅度，其具体取值可以根据实际要求而定，此处不做具体限定。
具体地，结合图3所示，在一个应用例中，获取待显示图像的区域A中每个像素点的像素值，以及前一帧显示图像中同一区域A’中的每个像素点的像素值后，可以将相同位置的像素点的像素值进行比较，获取二者的差值，将每两个像素点像素值的差值与预设像素阈值比较，并统计差值大于该预设像素阈值的像素点数量。例如，当区域A中的像素点301的像素值和区域A’中相同位置的像素点302的像素值的差值大于预设像素阈值时，将统计的像素点数量加1，其中可以采用计数器统计该像素点数量，即当有两个像素点像素值的差值大于预设像素阈值时，该计数器加1。
S123：判断统计的像素点数量是否大于预设数量，或者判断统计的像素点数量占该至少部分区域所有像素点数量的比例是否大于预设比例。
其中，该预设数量是预定设定的判定该待显示图像是动态画面所需的已统计的像素点的最小数量，该预设比例是预先设定的判定该待显示图像是动态画面所需的已统计像素点占该至少部分区域所有像素点数量的最小比例，其具体取值可以根据实际需求设置，此处不做具体限定。
S124：若判断结果为是，则判定待显示图像相对于前一帧显示图像的变化程度超过预设范围。
具体地，在上述应用例中，当计数器的值大于预设数量（如100），或者当计数器的值除以区域A的所有像素点数量得到的比值大于预设比例（如30%）时，则可以判定待显示图像相对于前一帧显示图像的变化程度超过预设范围，即相对于前一帧显示图像，该待显示图像是动态画面。
S13：将当前伽马电压调节为目标伽马电压，以得到目标伽马曲线。
其中，该目标伽马电压是基于检测到的环境色温和亮度等变化因素获取的伽马电压，其可以使得显示设备显示的内容根据环境的变化进行调整。
可选地，本实施例中，该显示驱动方法还可以包括：
S101：侦测环境色温和亮度。
S102：生成环境色温和亮度对应的目标伽马电压。
具体地，可以通过相机或传感器等装置侦测环境的色温和亮度变化，同时根据环境的色温和亮度变化，可以生成对应的目标伽马电压，以驱动显示面板，从而使得显示设备显示的内容根据环境的变化进行调整。
上述步骤S101~S102可以在步骤S13之前的任一步骤之前、之后或同时执行，此处不做具体限定。
S14：以目标伽马曲线驱动显示面板，以显示待显示图像。
具体地，由于对于动态画面而言，利用伽马曲线调节色温前后对应着不同的显示内容，画面变化本身就会带来亮度等显示特性的变化，因此对于动态画面，可以不需要进行伽马电压的内存运算，直接将当前伽马电压调节或者切换为目标伽马电压即可得到目标伽马曲线，根据目标伽马曲线校正驱动电压，并以校正后的驱动电压驱动显示面板显示该待显示图像，则可以使得该待显示图像根据环境色温和亮度等因素调节显示内容，可以提高显示灵活性。
本实施例中，获取待显示图像后，先判断待显示图像相对于前一帧显示图像的变化程度是否超过预设范围，若判断结果为是，则将当前伽马电压调节为目标伽马电压，以得到目标伽马曲线，以目标伽马曲线驱动显示面板，以显示待显示图像，从而在待显示图像相对于前一帧显示图像的变化程度超过预设范围时，不需要进行伽马电压内插运算，直接进行伽马电压的切换，进而可以减少不必要的伽马电压内插运算，降低处理芯片的功耗。
此外，当待显示图像相对于前一帧图像是静态画面，即待显示图像相对于前一帧显示图像的变化程度不大，没有超过预设范围时，还可以根据该待显示图像经过目标伽马曲线调节后的颜色和亮度变化是否超过人眼分辨范围，确定是否进行伽马电压的内存运算。
具体如图4所示，本申请显示驱动方法第二实施例包括：
S11：获取待显示图像。
S12：判断待显示图像相对于前一帧显示图像的变化程度是否超过预设范围。
若判断结果为是，则执行步骤S13，否则执行步骤S15。
S13：将当前伽马电压调节为目标伽马电压，以得到目标伽马曲线。
S14：以目标伽马曲线驱动显示面板，以显示待显示图像。
其中，上述步骤S11~S14的具体过程可以参考本申请显示驱动方法第一实施例的内容，此处不再重复。
S15：获取目标伽马电压对应的目伽马曲线。
其中，每个伽马电压对应一条伽马曲线，通过该伽马曲线可以校正驱动电压，以使得以该驱动电压驱动显示的画面亮度等变化在人眼感知时为线性变化。
S16：判断待显示图像经过目标伽马曲线校正后的颜色变化和亮度变化中是否至少一个超过人眼分辨范围。
若判断结果为是，则执行步骤S17。
其中，该人眼分辨范围包括颜色分辨范围和亮度分辨范围，具体范围可以根据人眼分辨率的先验知识得到，此处不做具体限定。
S17：对当前伽马曲线和目标伽马曲线进行插值运算，得到渐变伽马曲线。
其中，该渐变伽马曲线可以是一条，也可以是多条，此处不做具体限定。该插值运算可以采用现有伽马电压内插运算。
S18：以渐变伽马曲线驱动显示面板，以显示待显示图像。
可选地，若步骤S16的判断结果为否，则返回执行步骤S13。
具体地，在一个应用例中，当待显示图像相对于前一帧显示图像的变化程度不超过预设范围，即该待显示图像是静态画面时，可以预先获取采用目标伽马电压对应的目标伽马曲线校正后的待显示图像的颜色变化和亮度变化，然后判断该颜色变化和亮度变化中是否至少一个超过人眼分辨范围，例如判断所有像素点的平均颜色变化和平均亮度变化中是否至少一个超过人眼分辨范围，或者判断是否存在较大区域的像素点的颜色变化和亮度变化中至少一个超过人眼分辨范围，若超过或存在，则表明需要进行伽马电压内插运算。此时，对当前伽马曲线和目标伽马曲线进行插值运算，可以得到渐变伽马曲线，然后以该渐变伽马曲线校正驱动电压后，以校正后的驱动电压驱动显示面板显示该待显示图像，则可以使得显示内容的色温和亮度根据环境变化调节，提高显示效果。
此外，在待显示图像经过目标伽马曲线校正后的颜色变化和亮度变化均没有超过人眼分辨范围时，可以不需要进行伽马电压内插运算，直接将当前伽马电压切换为目标伽马电压，从而可以减少不必要的伽马电压内插运算，降低处理芯片的功耗。
在其他实施例中，判断待显示图像经过所述目标伽马曲线校正后的颜色变化和亮度变化中是否至少一个超过人眼分辨范围时，可以利用麦克亚当椭圆及人眼亮度分辨率进行判断。
具体如图5所示，本申请显示驱动方法第三实施例是在本申请显示驱动方法第二实施例的基础上，进一步限定步骤S16包括：
S161：判断待显示图像经过目标伽马曲线校正后的色温变化是否在麦克亚当椭圆范围内。
其中，麦克亚当椭圆内的颜色代表人眼感觉不出颜色太大变化的范围，称为颜色的宽容量。
具体地，在一个应用例中，可以判断该待显示图像经过目标伽马曲线校正后，每个像素点的色温变化是否均在麦克亚当椭圆范围内，或者将待显示图像划分为多个区域，判断各个区域的像素点的平均色温变化是否在麦克亚当椭圆范围内，又或者判断该待显示图像中所有像素点的平均色温变化是否在麦克亚当椭圆范围内。
S162：判断待显示图像经过目标伽马曲线校正后的亮度变化是否超过预设亮度范围。
其中，该预设亮度范围是预先设定的人眼感觉不出亮度太大变化的范围，由于人眼对亮度的分辨极限受个体和显示灰度差异影响，其具体取值可以根据实际精度需求设置，此处不做具体限定。
具体地，在一个应用例中，可以判断该待显示图像经过目标伽马曲线校正后，每个像素点的亮度变化是否均超过预设亮度范围，或者将待显示图像划分为多个区域，判断各个区域的像素点的平均亮度变化是否超过预设亮度范围，又或者判断该待显示图像中所有像素点的平均亮度变化是否超过预设亮度范围。
若色温变化不在麦克亚当椭圆范围内，和/或，亮度变化超过预设亮度范围，则执行步骤S163。
S163：判定待显示图像经过目标伽马曲线校正后的颜色变化和亮度变化中至少一个超过人眼分辨范围。
若色温变化在麦克亚当椭圆范围内，且亮度变化也不超过预设亮度范围，则判定待显示图像经过目标伽马曲线校正后的颜色变化和亮度变化均不超过人眼分辨范围。

    判断所述待显示图像经过目标伽马曲线校正后，所述待显示图像中每个像素点的色温变化是否均在麦克亚当椭圆范围内；
    将所述待显示图像划分为多个区域，判断各个区域的像素点的平均色温变化是否在麦克亚当椭圆范围内；或
    判断所述待显示图像中所有像素点的平均色温变化是否在麦克亚当椭圆范围内。
  17. 根据权利要求15所述的具有存储功能的装置，其中，所述程序被执行所述判断所述待显示图像经过所述目标伽马曲线校正后的亮度变化是否超过预设亮度范围包括：
    判断所述待显示图像经过目标伽马曲线校正后，所述待显示图像中每个像素点的亮度变化是否均超过预设亮度范围；
    将所述待显示图像划分为多个区域，判断各个区域的像素点的平均亮度变化是否超过预设亮度范围；或
    判断所述待显示图像中所有像素点的平均亮度变化是否超过预设亮度范围。
  18. 根据权利要求12所述的具有存储功能的装置，其中，所述程序被执行所述判断所述待显示图像相对于前一帧显示图像的变化程度是否超过预设范围包括：
    获取所述待显示图像至少部分区域每个像素点的像素值与所述前一帧显示图像中同一区域的对应像素点的像素值的差值；
    统计所述差值大于预设像素阈值的像素点数量；
    判断统计的所述像素点数量是否大于预设数量，或者判断统计的所述像素点数量占所述至少部分区域所有像素点数量的比例是否大于预设比例；
    若判断结果为是，则判定所述待显示图像相对于前一帧显示图像的变化程度超过预设范围。
  19. 根据权利要求12所述的具有存储功能的装置，其中，所述程序进一步被执行：
    侦测环境色温和亮度；
    生成所述环境色温和亮度对应的所述目标伽马电压。
