具体实施方式
为了使本发明的目的、技术方案和优点更加清楚，下面将结合附图对本发明作进一步地详细描述，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做出创造性劳动前提下所获得的所有其它实施例，都属于本发明保护的范围。
请参考图1，其示出了本发明各个实施例所涉及的一种应用环境的示意图，参见图1，涉及一种显示装置100，该显示装置100包括驱动设备110和显示面板120，该驱动设备110可以为显卡，显示装置100需要在驱动设备110的驱动下通过显示面板120实现图像显示。替代地或在一个实施例中，驱动设备110也可以独立于显示装置100而布置于显示装置100之外，并与其相耦接。
如图1所示，显示装置100还包括：驱动显示面板120的驱动电路(图1中未标出)，该驱动电路包括时序控制器130、栅极驱动电路140和源极驱动电路150，栅极驱动电路140用于对显示面板120中的各行像素器进行逐行扫描，源极驱动电路150用于为显示面板120的 各列像素器提供数据信号，时序控制器130分别与栅极驱动电路140、源极驱动电路150和驱动设备110连接，时序控制器130用于根据驱动设备110的驱动刷新率对栅极驱动电路140和源极驱动电路150输出的信号进行控制，以对显示显示装置100的刷新率进行调整。时序控制器130可以进一步适配有根据本公开实施例的刷新率调整电路300，关于刷新率调整电路300的详细描述将在下文参考图3a至3f给出。
替代地或在一个实施例中，显示装置100还可以包括计算机可读存储介质160，所述计算机可读存储介质160中存储有指令，当所述计算机可读存储介质160在计算机上运行时，使得计算机执行根据本公开实施例的方法。
本领域普通技术人员可以理解实现本公开实施例的全部或部分步骤可以通过硬件来完成，也可以通过程序来指令相关的硬件完成，所述的程序可以存储于计算机可读存储介质160中。替代地或在一个实施例中，计算机可读存储介质160可以与时序控制器130相耦接。计算机可读存储介质160可以是只读存储器，磁盘或光盘等。
显示装置100可以为液晶面板、电子纸、有机发光二极管(英文：Organic Light-Emitting Diode；简称：OLED)面板、手机、平板电脑、电视机、显示器、笔记本电脑、数码相框、导航仪等任何具有显示功能的产品或部件。
请参考图2a，其示出了本公开的一个实施例提供的一种刷新率调整方法的方法流程图，该刷新率调整方法可以由刷新率调整电路300来执行，如上所述，该刷新率调整电路300可以为图1所示的时序控制器022中的功能电路。参见图2a，该方法包括：步骤201，获取驱动设备当前的驱动刷新率。
其中，驱动设备可以为显示驱动设备，且具体可以为显卡。驱动设备可以向显示装置输入图像帧，驱动设备向显示装置输入图像帧的频率也即是驱动刷新率。
在本公开的多个实施例中，刷新率调整电路300可以通过显示装置接收到的图像帧的数量来获取驱动设备当前的驱动刷新率；或者，驱动设备可以实时向刷新率调整电路300发送驱动刷新率，刷新率调整电路300通过接收驱动设备发送的驱动刷新率来获取驱动设备当前的驱动刷新率；或者，刷新率调整电路300可以向驱动设备发送用于 获取驱动刷新率的获取请求，并接收驱动设备发送的获取响应，基于获取响应的内容获取驱动设备当前的驱动刷新率。本公开的各个实施例对驱动设备当前的驱动刷新率的获取方式不作限定。本公开的一个实施例中，假设驱动设备当前的驱动刷新率为f1。
需要说明的是，在本公开的多个实施例中，刷新率调整电路300可以实时获取驱动设备当前的驱动刷新率，当驱动刷新率变化速率较小时，刷新率调整电路300也可以每隔预设时间间隔获取驱动刷新率，并将获取到的驱动刷新率作为驱动设备当前的驱动刷新率。其中，预设时间间隔可以根据经验设置，本公开的各个实施例对此不作限定。此外，上述所列举的几种获取驱动刷新率的方案仅仅是示例性的，实际应用中，还可以采用其他方案获取驱动刷新率，且具体的获取过程可以参考相关技术，在此不再赘述。
步骤202，判断驱动刷新率是否小于预设的驱动刷新率阈值。
刷新率调整电路300获取驱动设备当前的驱动刷新率之后，可以判断驱动刷新率是否小于预设的驱动刷新率阈值。其中，驱动刷新率阈值可以记为f，f的具体取值可以根据实际经验设置，示例地，f＝30fps(中文：每秒传输帧数；英文：Frames PerSecond)，本公开的各个实施例对此不作限定。
在一个实施例中，刷新率调整电路300可以将驱动刷新率f1与驱动刷新率阈值f进行比较来判断驱动刷新率是否小于驱动刷新率阈值。
步骤203，当驱动刷新率f1小于驱动刷新率阈值f时，调整显示装置的显示刷新率，使调整后的显示刷新率为驱动刷新率的P倍，且调整后的显示刷新率f1大于驱动刷新率阈值f，P为大于1的整数。在一个示例中，请参考图2b，其示出了本公开的一个实施例提供的一种刷新率调整方法的一个具体步骤的方法流程图，该方法包括：
子步骤2031，当驱动刷新率小于驱动刷新率阈值时，确定当前接收的驱动设备传输的第一图像帧的传输时长。
其中，当前接收的驱动设备传输的第一图像帧的传输时刻可以位于当前时刻之前且距离当前时刻最近。在一个实施例中，显示装置中可以设置计时器和识别器，第一图像帧具有起始标识和结束标识，在驱动设备向显示装置传输第一图像帧的过程中，显示装置可以通过识别器对第一图像帧的起始标识和结束标识进行识别，当显示装置识别 到第一图像帧的起始标识时，显示装置启动计时器开始计时，当显示装置识别到第一图像帧的结束标识时，显示装置关闭计时器停止计时，刷新率调整电路300可以将显示装置停止计时的时刻与开始计时的时刻之间的时间差确定为第一图像帧的传输时长。需要说明的是，此处描述的确定第一图像帧的传输时长的方案仅仅是示例性的，实际应用中，还可以采用其他方案确定第一图像帧的传输时长，在此不再赘述。
需要说明的是，在本公开的一个实施例中，第一图像帧可以包括有效数据和无效数据，有效数据用于图像显示，无效数据不用于图像显示，该无效数据通常也可以称为消隐数据，显示装置接收驱动设备传输的第一图像帧后，可以对第一图像帧的有效数据进行存储，本公开的各个实施例对此不作限定。
示例地，请参考图2c，其示出了本公开的一个实施例提供的一种刷新率调整方法的示意图，参见图2c，驱动设备输入的(也即是驱动设备向显示装置传输的)第一图像帧F1包括有效数据1～n和无效数据BLANK，该有效数据1～n用于图像显示，无效数据BLANK不用于图像显示，且该第一图像帧F1的传输时长可以为Δt，显示装置接收该第一图像帧F1后，可以对有效数据1～n进行存储。
子步骤2032，采用与传输时长相等的输出时长输出P个第一图像帧。
刷新率调整电路300确定第一图像帧的传输时长后，可以采用与该传输时长相等的输出时长输出P个第一图像帧，使得显示装置的显示刷新率能够调整为驱动设备的驱动刷新率的P倍。在图2c中，P示为2.示例地，请参考图2d，其示出了本公开的一个实施例提供的一种采用与传输时长相等的输出时长输出P个第一图像帧的方法流程图，该方法包括：子步骤20321，确定采用第一传输速率输出P个第一图像帧的有效数据的有效输出时长。
其中，第一图像帧可以包括有效数据和无效数据，有效数据的输出时长可以为有效输出时长，无效数据的输出时长可以为无效输出时长。第一传输速率可以为固定传输速率，其可以为显示装置的点对点(英文：Point To Point；简称：P2P)接口速率，该第一传输速率的单位可以与显示装置的刷新率的单位相同，且第一传输速率的值不小于显示装置的最大刷新率的值，这样可以保证数据传输速率能够跟上 显示装置的刷新率。在一个实施例中，第一传输速率的单位可以为fps，通常情况下，显示装置的刷新率范围可以为30fps～150fps(或者30赫兹～150赫兹)，由此可知显示装置的最大刷新率可以为150fps，因此，第一传输速率可以大于150fps，本公开的各个实施例对此不作限定。
在本公开的一个实施例中，第一传输速率记为V f，该第一传输速率V f的单位可以为fps，根据该第一传输速率V f的单位可以确定，采用该第一传输速率V f输出一个第一图像帧的有效数据的有效输出时长可以为1/V f，从而采用该第一传输速率输出P个第一图像帧的有效数据的有效输出时长可以为P/V f。示例地，请继续参考图2c，该图2c以P＝2为例进行说明，显示装置输出每个第一图像帧F1的有效数据1～n的有效输出时长为1/V f，因此，显示装置输出2个第一图像帧F1的有效数据的有效输出时长为2/V f，也即是在图2c中有效输出时长为2/V f。
需要说明的是，上述描述的确定采用第一传输速率输出P个第一图像帧的有效数据的有效输出时长的方案仅仅是示例性的，实际应用中，还可以采用其他方案确定输出P个第一图像帧的有效数据的有效输出时长，在此不再赘述。
子步骤20322，根据传输时长和有效输出时长，确定每个第一图像帧对应的无效输出时长。
确定第一图像帧的传输时长和采用第一传输速率输出P个第一图像帧的有效数据的有效输出时长之后，刷新率调整电路300可以根据传输时长和有效输出时长，确定每个第一图像帧对应的无效输出时长。其中，每个第一图像帧对应的无效输出时长也即是输出每个第一图像帧的无效数据的时长，本公开的各个实施例对此不作限定。
在一个实施例中，P个第一图像帧中任意两个第一图像帧对应的无效输出时长相等，此时，刷新率调整电路300可以采用第一无效时长公式确定每个第一图像帧对应的无效输出时长，该第一无效时长公式可以为：T balnk1＝[Δt-(P/V f)]/P；其中，T balnk1表示每个第一图像帧对应的无效输出时长，Δt表示驱动设备向显示装置传输第一图像帧的传输时长，P/V f表示采用第一传输速率V f输出P个第一图像帧的有效数据的有效输出时长，V f表示第一传输速率。示例地，如图2c所示，每个第一图像帧F1对应的无效输出时长为T balnk1。
在一个实施例中，P个第一图像帧中存在至少两个第一图像帧对应 的无效输出时长不相等，此时，刷新率调整电路300可以在保证P个第一图像帧对应的无效输出时长之和等于[Δt-(P/V f)]的前提下，随机为每个第一图像帧分配无效输出时长，并将为每个第一图像帧分配的无效输出时长确定为每个第一图像帧对应的无效输出时长。需要说明的是，此处所描述的确定每个第一图像帧对应的无效输出时长方案仅仅是示例性的，实际应用中，当P个第一图像帧中存在至少两个第一图像帧对应的无效输出时长不相等时，刷新率调整电路300还可以采用其他方式确定每个第一图像帧对应的无效输出时长，在此不再赘述。
子步骤20323，根据每个第一图像帧对应的无效输出时长以及第二传输速率，在每个第一图像帧的有效数据的末尾充填无效数据得到处理后的P个第一图像帧。
刷新率调整电路300确定每个第一图像帧对应的无效输出时长后，可以根据每个第一图像帧对应的无效输出时长以及第二传输速率，在每个第一图像帧的有效数据的末尾充填无效数据得到处理后的P个第一图像帧。其中，第二传输速率为第一图像帧的无效数据的输出速率，该第二传输速率可以与第一传输速率相等，也可以与第一传输速率不等，本公开的各个实施例对此不作限定。优选地，第二传输速率与第一传输速率相等。示例地，请继续参考图2c，刷新率调整电路300根据每个第一图像帧F1对应的无效输出时长T blank1以及第二传输速率，在每个第一图像帧F1的有效数据n的末尾充填无效数据BLANK，得到处理后的2个第一图像帧F1。
子步骤20324，输出处理后的P个第一图像帧，其中，有效数据采用第一传输速率输出，无效数据采用第二传输速率输出。
在每个第一图像帧的有效数据的末尾充填无效数据后，刷新率调整电路300可以输出处理后的P个第一图像帧，使显示装置能够根据处理后的P个第一图像帧显示图像。其中，刷新率调整电路300可以采用第一传输速率V f输出每个第一图像帧的有效数据，采用第二传输速率输出每个第一图像帧的无效数据。在本公开的一个实施例中，数据是连续输出的，且刷新率调整电路300是按帧输出数据的，因此，在输出处理后的P个第一图像帧的过程中，刷新率调整电路300可以先输出首个第一图像帧的有效数据，然后再输出该首个第一图像帧的无效数据，接着再输出第二个第一图像帧的有效数据，然后再输出该 第二个第一图像帧的无效数据，依次类推。
示例地，如图2c所示，刷新率调整电路300采用第一传输速率V f输出第一图像帧F1的有效数据1～n，然后采用第二传输速率输出第一图像帧F1的无效数据BLANK，接着采用第一传输速率V f输出第一图像帧F1’的有效数据1～n，最后采用第二传输速率输出第一图像帧F1’的无效数据BLANK。本公开的一个实施例中，当驱动刷新率小于驱动刷新率阈值(30fps)时，调整显示刷新率为驱动刷新率的2倍，可以保证画面显示流畅。
替代地或在一个实施例中，在步骤204，当驱动刷新率不小于驱动刷新率阈值时，调整显示装置的显示刷新率，使调整后的显示刷新率等于驱动刷新率。
当在步骤202中刷新率调整电路300确定驱动刷新率不小于驱动刷新率阈值时，在步骤204中刷新率调整电路300调整显示装置的显示刷新率使调整后的显示刷新率等于驱动刷新率。请参考图2e，其示出了本公开的一个实施例提供的另一种调整显示装置的显示刷新率的方法流程图，参见图2e，该方法包括：
子步骤2041，当驱动刷新率不小于驱动刷新率阈值时，确定当前接收的驱动设备传输的第一图像帧的传输时长。
其中，该子步骤2041的具体实现过程可以参考上述子步骤2031，在此不再赘述。
子步骤2042，采用与传输时长相等的输出时长输出第一图像帧。
刷新率调整电路300确定第一图像帧的传输时长后，可以采用与该传输时长相等的输出时长输出第一图像帧，使得显示装置的显示刷新率能够与驱动设备的驱动刷新率相等，从而显示刷新率能够跟随驱动刷新率变化。请参考图2f，其示出了本公开的一个实施例提供的一种输出第一图像帧的方法流程图，该方法包括：
子步骤20421，确定采用第一传输速率输出第一图像帧的有效数据的有效输出时长。
其中，第一图像帧可以包括有效数据和无效数据，有效数据的输出时长可以为有效输出时长，无效数据的输出时长可以为无效输出时长。第一传输速率可以为固定传输速率，其可以为显示装置的P2P接口速率，该第一传输速率的单位可以与显示装置的刷新率的单位相同， 且第一传输速率的值不小于显示装置的最大刷新率的值，这样可以保证数据传输速率能够跟上显示装置的刷新率。在一个实施例中，第一传输速率的单位可以为fps，通常情况下，显示装置的刷新率范围可以为30fps～150fps(或者30赫兹～150赫兹)，由此可知显示装置的最大刷新率可以为150fps，因此，第一传输速率可以大于150fps，本公开的各个实施例对此不作限定。
在本公开的一个实施例中，第一传输速率可以为V f，该第一传输速率V f的单位可以为fps，根据该第一传输速率V f的单位可以确定，采用该第一传输速率V f输出第一图像帧的有效数据的有效输出时长可以为1/V f。示例地，请参考图2g，其示出了本公开的一个实施例提供的一种刷新率调整方法的另一个示意图，参见图2g，驱动设备输入的第一图像帧F1包括有效数据1～n和无效数据BLANK，且该第一图像帧F1的传输时长可以为Δt，显示装置输出第一图像帧F1的有效数据1～n的有效输出时长为1/V f。
子步骤20422，根据传输时长和有效输出时长，确定第一图像帧对应的无效输出时长。
确定第一图像帧的传输时长和采用第一传输速率输出第一图像帧的有效数据的有效输出时长之后，刷新率调整电路300可以根据传输时长和有效输出时长，确定第一图像帧对应的无效输出时长。其中，第一图像帧对应的无效输出时长也即是输出第一图像帧的无效数据的时长，本公开的各个实施例对此不作限定。
在一个实施例中，刷新率调整电路300可以采用第二无效时长公式确定第一图像帧对应的无效输出时长，该第二无效时长公式可以为：T balnk2＝Δt-(1/V f)；其中，T balnk2表示第一图像帧对应的无效输出时长，Δt表示驱动设备向显示装置传输第一图像帧的传输时长，1/V f表示采用第一传输速率V f第一图像帧的有效数据的有效输出时长，V f表示第一传输速率。示例地，如图2g所示，第一图像帧F1对应的无效输出时长为T balnk2。
子步骤20423，根据第一图像帧对应的无效输出时长以及第二传输速率，在第一图像帧的有效数据的末尾充填无效数据得到处理后的第一图像帧。
刷新率调整电路300确定第一图像帧对应的无效输出时长后，可 以根据第一图像帧对应的无效输出时长以及第二传输速率，在第一图像帧的有效数据的末尾充填无效数据得到处理后的第一图像帧。其中，第二传输速率为第一图像帧的无效数据的输出速率，该第二传输速率可以与第一传输速率相等，也可以与第一传输速率不等，本公开的各个实施例对此不作限定。优选地，第二传输速率与第一传输速率相等。示例地，请继续参考图2g，刷新率调整电路300根据第一图像帧F1对应的无效输出时长以及第二传输速率，在第一图像帧F1的有效数据n的末尾充填无效数据BLANK，得到处理后第一图像帧F1。
子步骤20424，输出处理后的第一图像帧，其中，有效数据采用第一传输速率输出，无效数据采用第二传输速率输出。
在第一图像帧的有效数据的末尾充填无效数据后，刷新率调整电路300可以输出处理后的第一图像帧，使显示装置能够根据处理后的第一图像帧显示图像。其中，刷新率调整电路300可以采用第一传输速率V f输出第一图像帧的有效数据，采用第二传输速率输出第一图像帧的无效数据。在本公开的一个实施例中，数据是连续输出的，在输出处理后的第一图像帧的过程中，刷新率调整电路300可以先输出第一图像帧的有效数据，然后再输出该第一图像帧的无效数据。示例地，如图2g所示，刷新率调整电路300采用第一传输速率V f输出第一图像帧F1的有效数据1～n，然后采用第二传输速率输出第一图像帧F1的无效数据BLANK。
本公开的各个实施例提供的刷新率调整方法，可以采用P2P接口以第一传输速率输出有效数据，使得能够调整无效传输时间(BLANK时间)，进而动态调整每个图像帧的输出时间，通过调整每个图像帧的输出时间来达到调整显示刷新率。
