 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。
具体的，请参阅图1，图1为本申请实施例提供的显示面板的驱动方法的流程示意图，如图1所示，本申请实施例提供的显示面板的驱动方法包括：
101、接收待显示画面的数据信号。
其中，待显示画面的数据信号中不仅包括视频信号，还包括亮度信号，视频信号用于控制显示面板的一些指定的像素单元发光，并且对像素单元发光的颜色也有一定的限定，从而使显示面板上形成色彩斑斓的显示图像。亮度信号是用于控制显示面板中发光的像素单元的亮度，而且亮度信号主要指的就是频率信号。
102、根据待显示画面的数据信号确定待显示画面的实时频率。
其中，因数据信号中包括亮度信号，而亮度信号主要指的就是频率信号，因此，可以从待显示画面的数据信号中获取待显示面板的实时频率。
其中，实时频率指的是在显示面板正常工作时，显示面板接收到用于使显示面板正常显示画面的频率，其中，此频率与时间相关联，会随着时间的变化发生变化，具有时效性。比如，在某一时刻，显示面板接收到的用于使显示面板正常显示画面的频率就是显示面板在那一时刻的实时频率。
103、将待显示画面的实时频率与多个预设频率进行比较，得到与待显示画面的实时频率最接近的预设频率。
其中，预设频率包括第一预设频率、第二预设频率以及第三预设频率，第一预设频率小于第二预设频率，第二预设频率小于第三预设频率。
其中，在一种实施方式中，第一预设频率为48赫兹，第二预设频率为60赫兹，第三预设频率为165赫兹。第一预设频率、第二预设频率以及第三预设频率也可以为其他数值，只需要满足第一预设频率小于第二预设频率，第二预设频率小于第三预设频率即可。
具体的，请参阅图1、图2，图2为本申请实施例提供的显示面板的驱动方法的第一子流程示意图，如图2所示，本申请实施例提供的显示面板的驱动方法中的步骤103包括：
1031、分别获取待显示画面的实时频率与第一预设频率、第二预设频率以及第三预设频率的差值，并将待显示画面的实时频率与第一预设频率的差值记为第一差值，将待显示画面的实时频率与第二预设频率的差值记为第二差值，将待显示画面的实时频率与第三预设频率的差值记为第三差值。
其中，获取实时频率与预设频率的差值主要是为了获取实时频率与预设频率的相似度，获取实时频率与预设频率的相似度也就是为了找出与实时频率最接近的预设频率。
其中，假设预设频率的值为A，第一预设频率的值为A1，第二预设频率的值为A2，第三预设频率的值为A3；实时频率的值为B；预设频率与实时频率的差值为C，第一差值为C1，第二差值为C2，第三差值为C3，则此时，C=|A-B|，C1=|A1-B|，C2=|A2-B|，C3=|A3-B|。
其中，预设频率与实时频率的差值C为预设频率的值A和实时频率的值B相减得到的值的绝对值，同理，C1、C2、C3也是绝对值，因此，才可以通过比较预设频率与实时频率的差值C来获取实时频率与预设频率的相似度。
1032、比较第一差值、第二差值以及第三差值。
其中，比较第一差值、第二差值以及第三差值，就是比较C1、C2以及C3的大小，找出他们之中的最小值。
1033、若第一差值最小，则第一预设频率为与待显示画面的实时频率最接近的预设频率，若第二差值最小，则第二预设频率为与待显示画面的实时频率最接近的预设频率，若第三差值最小，则第三预设频率为与待显示画面的实时频率最接近的预设频率。
其中，比较不同差值C的大小，可以得到不同预设频率与实时频率的相似度，而预设频率与实时频率的差值C越小，就证明预设频率与实时频率越相似。
另外，在本申请所提供的实施例中，只有第一预设频率、第二预设频率以及第三预设频率，因此，只需要比较第一差值C1、第二差值C2以及第三差值为C3之间的大小，找出它们之中最小的差值，即可得到第一预设频率、第二预设频率以及第三预设频率中谁为与实时频率最相似的预设频率，而且与实时频率最相似的预设频率也就是与实时频率最接近的预设频率。
104、根据与待显示画面的实时频率最接近的预设频率调用与之对应的伽玛电压，并输出至显示面板。
其中，调用与待显示画面的实时频率最接近的预设频率对应的伽玛电压，需要通过控制第一控制引脚（pin）以及第二控制引脚输出特定的电平信号，从而输出调用与待显示画面的实时频率最接近的预设频率对应的伽玛电压的控制信号，此控制信号控制其他引脚输出与待显示画面的实时频率最接近的预设频率对应的伽玛电压至显示面板。
具体的，请参阅图1、图3，图3为本申请实施例提供的显示面板的驱动方法的第二子流程示意图，如图所示，本申请实施例提供的显示面板的驱动方法中步骤104包括：
1041、若第一预设频率为与待显示画面的实时频率最接近的预设频率，则调用与第一预设频率对应的伽玛电压输出至显示面板。
其中，若要调用与第一预设频率对应的伽玛电压，则需要第一控制引脚以及第二控制引脚均输出高电平信号，以输出调用与第一预设频率对应的伽玛电压的控制信号，此控制信号控制其他引脚输出与第一预设频率对应的伽玛电压至显示面板，以使显示面板显示画面。
其中，第一控制引脚以及第二控制引脚电路结构相似，都是通过控制其内部的三极管来输出不同的电平信号（高电平信号或低电平信号）。
1042、若第二预设频率为与待显示画面的实时频率最接近的预设频率，则调用与第二预设频率对应的伽玛电压输出至显示面板。
其中，若要调用与第二预设频率对应的伽玛电压，则需要第一控制引脚输出低电平信号，第二控制引脚均输出高电平信号，以输出调用与第二预设频率对应的伽玛电压的控制信号，此控制信号控制其他引脚输出与第二预设频率对应的伽玛电压至显示面板。
1043、若第三预设频率为与待显示画面的实时频率最接近的预设频率，则调用与第三预设频率对应的伽玛电压输出至显示面板。
其中，若要调用与第三预设频率对应的伽玛电压，则需要第一控制引脚输出高电平信号，第二控制引脚均输出低电平信号，以输出调用与第三预设频率对应的伽玛电压的控制信号，此控制信号控制其他引脚输出与第三预设频率对应的伽玛电压至显示面板。
进一步地，请参阅图4，图4为本申请实施例提供的显示面板的驱动方法中步骤104的实施状态示意图。如图4所示，本申请实施例提供的显示面板的驱动方法中步骤104的实施状态示意图中包括伽玛电压模块104a、第一控制引脚104b，第二控制引脚104c、其他引脚104d以及显示面板104e。
其中，当第一控制引脚104b输出高电平信号以及第二控制引脚104c输出高电平信号时，第一控制引脚104b以及第二控制引脚104c输出第一控制信号至其他引脚104d，其他引脚104d依据第一控制信号调用与第一预设频率对应的伽玛电压，并输出至显示面板104e。
其中，当第一控制引脚104b输出低电平信号以及第二控制引脚104c输出高电平信号时，第一控制引脚104b以及第二控制引脚104c输出第二控制信号至其他引脚104d，其他引脚104d依据第二控制信号调用与第二预设频率对应的伽玛电压，并输出至显示面板104e。
其中，当第一控制引脚104b输出高电平信号以及第二控制引脚104c输出低电平信号时，第一控制引脚104b以及第二控制引脚104c输出第三控制信号至其他引脚104d，其他引脚104d依据第三控制信号调用与第三预设频率对应的伽玛电压，并输出至显示面板104e。
其中，由于第一控制引脚104b与第二控制引脚104c是不同的两个引脚，因此第二控制信号和第三控制信号是不同的两个信号，因此，其他引脚104d根据第二控制信号调用的伽玛电压与根据第三控制信号调用的伽玛电压是不同的，不会产生误调用的情况。
其中，在一种实施方式中，高电平信号的电位为3.3伏特（V），低电平信号的电位为0伏特。
具体的，请参阅图5，图5为本申请实施例提供的显示面板的另一种驱动方法的流程示意图，如图5所示，本申请实施例提供的显示面板的另一种驱动方法包括：
201、汇总显示面板的频率，并从中筛选出第一预设频率、第二预设频率以及第三预设频率。
其中，第一预设频率为显示面板的所有频率中频率最低的频率；第三预设频率为显示面板的所有频率中频率最高的频率；通过此标准，就可以筛选出第一预设频率以及第三预设频率。
而第二预设频率需要根据显示面板的频率在显示同一显示画面时，显示画面的亮度来确定，其中，在采用显示面板的频率在显示同一显示画面时，采用第二预设频率与采用第一预设频率以及第三预设频率相比，显示画面的亮度差异最大，由此，就可以从显示面板的所有频率中筛选出第二预设频率。
202、产生三组与第一预设频率、第二预设频率以及第三预设频率一一对应的伽玛电压，并存储三组伽玛电压。
其中，当把这三组伽玛电压输出至显示面板，且用于显示同一画面时，显示画面基本没有亮度差。
203、接收待显示画面的数据信号。
204、根据待显示画面的数据信号确定待显示画面的实时频率。
205、将待显示画面的实时频率与多个预设频率进行比较，以得到与待显示画面的实时频率最接近的预设频率。
206、根据与待显示画面的实时频率最接近的预设频率调用与之对应的伽玛电压，并输出至显示面板。
在本申请提供的显示面板的驱动方法中，由于显示面板在采用预设频率显示同一画面时，只要输出与其对应的伽玛电压至显示面板，显示画面就不会存在亮度差，因此通过将待显示画面的实时频率与预设频率比较，从而得到与待显示画面的实时频率最接近的预设频率，并把与待显示画面的实时频率最接近的预设频率对应的伽玛电压输出至显示面板，显示面板在显示同一画面时也不会存在亮度差，从而可以解决带有FreeSync功能的高频显示器在开启FreeSync功能后出现画面闪烁现象，进而可以给用户提供更优质的游戏体验。
具体的，请参阅图6，图6为本申请实施例提供的显示面板的驱动装置的结构示意图，如图6所示，本申请实施例提供的显示面板的驱动装置30包括逻辑控制模块301以及伽玛电压模块302。
其中，逻辑控制模块301接入待显示画面的数据信号，且与伽玛电压模块302连接；逻辑控制模块301用于接收待显示画面的数据信号，并根据待显示画面的数据信号确定待显示画面的实时频率，将待显示画面的实时频率与多个预设频率进行比较，以得到与待显示画面的实时频率最接近的预设频率，并输出控制信号至伽玛电压模块302。
逻辑控制模块301还包括接收单元、确定单元、比较单元以及第一输出单元。其中，接收单元用于接收待显示画面的数据信号，确定单元用于根据待显示画面的数据信号确定待显示画面的实时频率，比较单元用于将待显示画面的实时频率与多个预设频率进行比较，以得到与待显示画面的实时频率最接近的预设频率，第一输出单元用于根据比较单元得到的结果输出控制信号至伽玛电压模块302。
另外，逻辑控制模块301接收到的待显示画面的数据信号中，不仅包含用于代表显示画面亮度的实时频率，还包括代表显示画面显示内容的图像信号，因此逻辑控制模块301还用于把从接收到的待显示画面的数据信号提取到的图像信号输出至显示面板，以使显示面板正常显示画面。
其中，伽玛电压模块302与逻辑控制模块301以及显示面板连接；伽玛电压模块302用于根据控制信号调用与待显示画面的实时频率最接近的预设频率对应的伽玛电压，并输出至显示面板，以使显示面板显示画面。
伽玛电压模块302还包括调用单元以及第二输出单元。其中，调用单元用于根据控制信号调用与待显示画面的实时频率最接近的预设频率对应的伽玛电压，第二输出单元用于输出伽玛电压至显示面板，以使显示面板显示画面。
其中，预设频率对应的伽玛电压是提前通过一定的测试获取的，并存储于伽玛电压模块302中，因此当伽玛电压模块302接收到逻辑控制模块301输出的控制信号时，能从伽玛电压模块302存储的伽玛电压中调取所需的伽玛电压。
其中，预设频率包括第一预设频率、第二预设频率以及第三预设频率，第一预设频率小于第二预设频率，第二预设频率小于第三预设频率。
其中，在一种实施方式中，第一预设频率为48赫兹，第二预设频率为60赫兹，第三预设频率为165赫兹。第一预设频率、第二预设频率以及第三预设频率也可以为其他数值，只需要满足第一预设频率小于第二预设频率，第二预设频率小于第三预设频率即可。
具体的，请参阅图6，图7，图7为本申请实施例提供的显示面板的另一种驱动装置的结构示意图，如图7所示，本申请实施例提供的显示面板的另一种驱动装置40包括逻辑控制模块401、伽玛电压模块402以及电源模块403，其中，逻辑控制模块401的输出端与伽玛电压模块402的输入端连接，且电源模块403的输出端与逻辑控制模块401以及伽玛电压模块402的输入端均连接。
其中，逻辑控制模块401以及伽玛电压模块402与逻辑控制模块301以及伽玛电压模块302所起到的作用一致，在此就不再一一赘述。而电源模块403主要用于给逻辑控制模块401以及伽玛电压模块402供给工作电流。
在本申请提供的显示面板的驱动装置中，由于显示面板在采用预设频率显示同一画面时，只要输出与其对应的伽玛电压至显示面板，显示画面就不会存在亮度差，因此通过将待显示画面的实时频率与预设频率比较，从而得到与待显示画面的实时频率最接近的预设频率，并把与待显示画面的实时频率最接近的预设频率对应的伽玛电压输出至显示面板，显示面板在显示同一画面时也不会存在亮度差，从而可以解决带有FreeSync功能的高频显示器在开启FreeSync功能后出现画面闪烁现象，进而可以给用户提供更优质的游戏体验。
