图1为本发明实施例提供的一种显示面板的控制装置的结构示意图。

图3为本发明实施例提供的一种显示面板的控制方法的流程图。
具体实施方式
下面将结合本发明实施例中的附图，对本发明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发明一部分实施例，而不是全部的实施例。基于本发明中的实施例，本领域普通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，都属于本发明保护的范围。
本发明的说明书和权利要求书及上述附图中的术语“第一”、“第二”和“第三”等是用于区别不同对象，而非用于描述特定顺序。此外，术语“包括”以及它们任何变形，意图在于覆盖不排他的包含。例如包含了一系列步骤或单元的过程、方法、系统、产品或设备没有限定于已列出的步骤或单元，而是可选地还包括没有列出的步骤或单元，或可选地还包括对于这些过程、方法、产品或设备固有的其它步骤或单元。
图1所示为本发明实施例提供的一种显示面板的控制装置的结构示意图，如图1所示，所述显示面板的控制装置10包括：时序控制器200、源极驱动300、以及栅极驱动400，其中，所述源极驱动300和栅极驱动400分别与液晶显示面板500电性连接，所述时序控制器200分别与源极驱动300和栅极驱动400电性连接。
所述时序控制器200用于为所述源极驱动300和栅极驱动400提供必要的时序控制信号，所述时序控制器200接收前端传输的低压差分信号，并将信号转化之后，通过输出相应的时序控制信号来驱动液晶显示面板500，使每一个像素点显示对应的像素电压。所述时序控制器200输出的时序控制信号包括：帧图像起始信号、栅极驱动时钟信号、源极驱动数据源行锁存信号以及极性翻转信号。
在本实施方式中，所述控制装置还包括温度检测模块600，所述温度检测装置600分别与所述源极驱动300和时序控制器200电性连接。可以理解的是，所述温度检测装置600也可以集成在所述源极驱动300上，本实施例并不以此为限。
所述温度检测模块600用于检测所述源极驱动300的芯片的温度，根据所述温度生成通知信号，并将所述通知信号发送至所述时序控制器200。具体的，所述温度检测模块600通过热敏电阻检测源极驱动300的芯片的温度，根据温 度生成通知信号，其中，所述通知信号为电压信号。
所述时序控制器200用于获取所述通知信号指示的温度，若所述温度超过预设的温度范围阈值，则根据所述温度生成控制信号，并将所述控制信号发送至所述源极驱动300。具体的，所述时序控制器200接收温度检测模块600发送的通知信号，解析所述通知信号，获取所述通知信号中的电压信号指示的温度，判断所述温度是否超过预设的温度范围阈值，其中，超过预设的温度范围阈值包括高于温度范围阈值的最高值以及低于温度范围阈值的最低值。若温度超过预设的温度范围阈值，表明此时源极驱动的工作温度已经不正常，如果不进行相应的调整，则可能会导致液晶显示面板无法正常工作。因此，此时根据温度生成控制信号，并发送所述控制信号至源极驱动300。本领域技术人员可以理解的是，引起温度超过预设温度范围阈值的原因有多种，可以是采用了更高的解析度，导致功耗过高；也可以是环境温度过高或者环境温度过低，本实施例并不以此为限。
所述源极驱动300用于根据所述控制信号切换所述显示面板的极性翻转方式。具体的，所述控制信号为极性翻转控制信号，源极驱动300根据该控制信号切换显示面板的极性翻转方式。由于不同极性翻转方式下的功耗不同，因此，通过切换不同的极性翻转方式，能够改变功耗，从而调整温度。当源极驱动300当前的温度过高时，通过切换为功耗较低的极性翻转方式，能够降低功耗，从而降低温度；当源极驱动300当前的温度过低时，通过切换为功耗较高的极性翻转方式，能够增加功耗，从而增加温度，经过上述方式，可以使得源极驱动的温度维持在合理的范围内，从而保证显示面板的正常运转，减少故障的产生。
上述可知，本发明实施例中的显示面板的控制装置，通过检测源极驱动的芯片的温度，在温度超过预设范围时，调整显示面板的极性翻转方式，通过调整极性翻转方式来调整显示面板的功耗，使得显示面板能够工作于合适的功耗之下，从而保证源极驱动的芯片能够处于正常的工作温度范围之内，保证显示面板的正常运转，减少故障的产生。
具体的，所述极性翻转方式包括：帧翻转、列翻转、行翻转、2行翻转以及点翻转。为了避免直流阻绝效应以及直流残留的发送，液晶显示面板中的每 个像素液晶本身必须以极性翻转的方式来驱动，但就像素阵列而言，在阵列中的相邻像素，却不一定要以相同的极性来驱动，因此，根据相邻像素不同的极性驱动方式，极性翻转方式可以有多种方式。
图2所示为本发明实施例中极性翻转方式的示意图。如图所示，在图2左列为各种翻转方式当前帧下的电压极性，右列为各种翻转方式下一帧的电压极性，图2的每一行表示了一种翻转方式下当前帧和下一帧的电压极性。根据每一帧各个像素的电压极性的不同，可以分为多种方式。如图2第一行所示，当前帧上的像素所储存的电压极性都是相同的，此时即为帧翻转，相应的，下一帧的像素所储存的电压极性都会与当前帧相反；如图2第二行所示，当前帧同一列的像素所储存的电压极性是相同的，且左右相邻的列上的像素所储存的电压极性相反，此时为列翻转；如图2第三行所示，当前帧同一行的像素所储存的电压极性相同，且上下相邻的行上的像素所储存的电压极性相反，此时为行翻转；如图2第四行所示，当前帧上同两行的像素所储存的电压极性相同，且上下相邻的两行上的像素所储存的电压极性相反，此时为2行翻转；如图2第五行所示，当前帧上每个像素所储存的电压极性，都与其上下左右相邻的像素所储存的电压极性相反，此时为点翻转。本领域技术人员以理解的是，极性翻转方式还可以是其他方式，本实施例并不以此为限。
由于电压的变化频率关系，不同极性翻转方式下的功耗不同，在本实施方式中，各种极性翻转方式的功耗大小关系如下所示：点翻转>行翻转>2行翻转>列翻转>帧翻转。因此，根据极性翻转方式的功耗大小关系，在源极驱动300的温度超过预设的温度阈值时，通过切换当前的极性翻转方式，能够实现调整功耗，进而维持温度在合理范围内。
具体的，时序控制器200在判断温度是否超过预设的温度范围阈值时，所述预设的温度范围阈值包括第一温度阈值以及第二温度阈值，其中，所述第一温度阈值高于所述第二温度阈值，所述温度超过预设的温度范围阈值包括所述温度高于所述第一温度阈值以及所述温度低于所述第二温度阈值。由于源极驱动只能工作在合适的温度范围之内，当温度过高或者过低时都会导致无法正常工作，因此，在判断温度是否超过温度范围阈值时，包括了判断温度是否过高或者温度是否过低。所述温度范围阈值取决于液晶面板的具体结构。在本实施 方式中，所述温度范围阈值可以设置为：0—40摄氏度，即第一温度阈值为40摄氏度，第二温度阈值为0摄氏度。在其他实施方式中，由于液晶面板的制作工艺和结构不一样，温度范围阈值也可以不同，比如也可以是-40—80摄氏度，即第一温度阈值为80摄氏度，第二温度阈值为-40摄氏度，本实施例并不以此为限。
具体的，若时序控制器200判断所述温度高于所述第一温度阈值，此时所述时序控制器200根据所述温度生成第一控制信号，并将所述第一控制信号发送至所述源极驱动300。温度高于第一温度阈值表明此时源极驱动300的温度过高，需要降低功耗。因此，源极驱动300在接收到第一控制信号之后，根据第一控制信号切换所述显示面板的极性翻转方式，其中，切换后的极性翻转方式下的功耗低于切换前的极性翻转方式下的功耗，从而实现降低功耗，进而降低温度。源极驱动300可以根据各个极性翻转方式的功耗大小关系，切换当前的极性翻转方式，比如，若当前的极性翻转方式为点翻转，则切换为行翻转。在其他实施方式中，可以为极性翻转方式设置不同的级别，根据功耗大小排定优先级别，功耗最高的点翻转级别最高，功耗最低的帧翻转级别最低，当需要降低功耗时，则切换至下一级别的极性翻转方式。
具体的，若时序控制器200判断所述温度低于所述第二温度阈值，此时所述时序控制器200根据所述温度生成第二控制信号，并将所述第二控制信号发送至所述源极驱动300。温度低于第二温度阈值表明此时源极驱动300的温度过低，需要提高功耗。因此，源极驱动300在接收到第二控制信号之后，根据第二控制信号切换所述显示面板的极性翻转方式，其中，切换后的极性翻转方式下的功耗高于切换前的极性翻转方式下的功耗，从而实现提高功耗，进而提高温度。源极驱动300可以根据各个极性翻转方式的功耗大小关系，切换当前的极性翻转方式，比如，若当前的极性翻转方式为帧翻转，则切换为列翻转。在其他实施方式中，可以为极性翻转方式设置不同的级别，根据功耗大小排定级别，功耗高的点翻转级别最高，功耗最低的帧翻转级别最低，当需要增加功耗时，则切换至上一级别的极性翻转方式。
上述可知，本发明实施例中的显示面板的控制装置，通过检测源极驱动的芯片的温度，在温度高于预设阈值时，调整为功耗较低的极性翻转方式；当温 度低于预设阈值时，调整为功耗较高的极性翻转方式，通过调整极性翻转方式来调整显示面板的功耗，使得显示面板能够工作于合适的功耗之下，从而保证源极驱动的芯片能够处于正常的工作温度范围之内，保证显示面板的正常运转，减少故障的产生。
图3为本发明实施例提供的一种显示面板的控制方法的流程图。该显示面板包括：时序控制器、源极驱动、以及栅极驱动，其中，所述源极驱动和栅极驱动分别与液晶显示面板电性连接，所述时序控制器分别与源极驱动和栅极驱动电性连接。该显示面板还包括温度检测模块，所述温度检测模块分别与所述源极驱动和时序控制器电性连接。该显示面板的控制方法包括以下步骤S301-S304。
在步骤S301中，检测所述显示面板的源极驱动的芯片的温度，根据所述温度生成通知信号。
具体的，温度检测模块检测所述源极驱动的芯片的温度，根据所述温度生成通知信号，并将所述通知信号发送至所述时序控制器。在本实施方式中，所述温度检测模块通过热敏电阻检测源极驱动的芯片的温度，根据温度生成通知信号，其中，所述通知信号为电压信号。
在步骤S302中，获取所述通知信号指示的温度，若所述温度超过预设的温度范围阈值，则根据所述温度生成控制信号。
具体的，所述时序控制器接收温度检测模块发送的通知信号，解析所述通知信号，获取所述通知信号中的电压信号指示的温度，判断所述温度是否超过预设的温度范围阈值，其中，超过预设的温度范围阈值包括高于温度范围阈值的最高值以及低于温度范围阈值的最低值。若温度超过预设的温度范围阈值，表明此时源极驱动的工作温度已经不正常，如果不进行相应的调整，则可能会导致液晶显示面板无法正常工作。因此，此时根据温度生成控制信号，并发送所述控制信号至源极驱动。
在其他实施方式中，所述预设的温度范围阈值包括第一温度阈值以及第二温度阈值，其中，所述第一温度阈值高于所述第二温度阈值，所述温度超过预设的温度范围阈值包括所述温度高于所述第一温度阈值以及所述温度低于所述第二温度阈值。由于源极驱动只能工作在合适的温度范围之内，当温度过高 或者过低时都会导致无法正常工作，因此，在判断温度是否超过温度范围阈值时，包括了判断温度是否过高或者温度是否过低。
若时序控制器判断所述温度高于所述第一温度阈值，此时所述时序控制器根据所述温度生成第一控制信号，并将所述第一控制信号发送至所述源极驱动。
若时序控制器判断所述温度低于所述第二温度阈值，此时所述时序控制器根据所述温度生成第二控制信号，并将所述第二控制信号发送至所述源极驱动。
在步骤S303中，根据所述控制信号切换所述显示面板的极性翻转方式。
具体的，所述控制信号为极性翻转控制信号，源极驱动根据该控制信号切换显示面板的极性翻转方式。由于不同极性翻转方式下的功耗不同，因此，通过切换不同的极性翻转方式，能够改变功耗，从而调整温度。当源极驱动当前的温度过高时，通过切换为功耗较低的极性翻转方式，能够降低功耗，从而降低温度；当源极驱动当前的温度过低时，通过切换为功耗较高的极性翻转方式，能够增加功耗，从而增加温度，经过上述方式，可以使得源极驱动的温度维持在合理的范围内，从而保证显示面板的正常运转，减少故障的产生。
具体的，所述极性翻转方式包括：帧翻转、列翻转、行翻转、2行翻转以及点翻转。为了避免直流阻绝效应以及直流残留的发送，液晶显示面板中的每个像素液晶本身必须以极性翻转的方式来驱动，但就像素阵列而言，在阵列中的相邻像素，却不一定要以相同的极性来驱动，因此，根据相邻像素不同的极性驱动方式，极性翻转方式可以有多种方式。
在其他实施方式中，源极驱动在接收到第一控制信号之后，根据第一控制信号切换所述显示面板的极性翻转方式，其中，切换后的极性翻转方式下的功耗低于切换前的极性翻转方式下的功耗，从而实现降低功耗，进而降低温度。
源极驱动在接收到第二控制信号之后，根据第二控制信号切换所述显示面板的极性翻转方式，其中，切换后的极性翻转方式下的功耗高于切换前的极性翻转方式下的功耗，从而实现提高功耗，进而提高温度。
上述可知，本发明实施例中的显示面板的控制方法，通过检测源极驱动的芯片的温度，在温度高于预设阈值时，调整为功耗较低的极性翻转方式；当温 度低于预设阈值时，调整为功耗较高的极性翻转方式，通过调整极性翻转方式来调整显示面板的功耗，使得显示面板能够工作于合适的功耗之下，从而保证源极驱动的芯片能够处于正常的工作温度范围之内，保证显示面板的正常运转，减少故障的产生。
