相关技术中，如图1所示，时序控制器接收的视频流包括多个初始显示帧(F1、F2、F3)，各初始显示帧包括发光阶段S1和消隐阶段S2。为了实现变频，从初始显示帧F1到初始显示帧F3，各初始显示帧中的消隐阶段S2的时间不断变长，以使帧频不断变小。然后，时序控制器根据视频流生成的亮度控制信号为脉冲信号，该脉冲信号包括多个脉冲P。亮度控制信号对应于各初始显示帧的部分的占空比发生了变化，容易导致闪烁的发生。
图2是一显示装置的示意性框图。图3是视频流的示意图。图4是修正显示帧与亮度控制信号的示意图。本公开实施方式提供一种时序控制器2的控制方法。其中，该时序控制器2用于显示装置。该显示装置还可以包括处理器1和显示面板3。该控制方法可以包括：
步骤S10、接收并存储视频流，该视频流包括顺序排列的n个初始显示帧(F1、F2、F3…Fn)，n大于或等于2，从第1个初始显示帧F1到第n个初始显示帧Fn，初始显示帧的帧频依次增大或减小。
步骤S20、根据n个初始显示帧生成亮度控制信号以及n个修正显示帧(XF1、XF2、XF3…XFn)，n个修正显示帧与n个初始显示帧对应；亮度控制信号为脉冲信号，且包括n个控制区段K，n个控制区段K与n个修正显示帧对应。
步骤S30、将亮度控制信号与n个修正显示帧发送至显示面板3，以使显示面板3根据修正显示帧进行显示。
本公开实施方式的控制方法，根据n个初始显示帧生成亮度控制信号以及n个修正显示帧，n个修正显示帧与n个初始显示帧对应，将亮度控制信号与n个修正显示帧发送至显示面板3，以使显示面板3根据修正显示帧进行 显示，避免显示面板3根据初始显示帧进行显示，提高了显示效果。
下面对本公开实施方式的控制方法的各步骤进行详细说明：
在步骤S10中，接收并存储视频流，所述视频流包括顺序排列的n个初始显示帧(F1、F2、F3…Fn)，n大于或等于2，从第1个初始显示帧到第n个初始显示帧，初始显示帧的帧频依次增大或减小。
该视频流可以由处理器1生成。具体地，上述的显示装置还可以包括存储器。该存储器中可以存储有多个软件应用。该软件应用可以表示视频游戏、虚拟现实(VR)或增强现实(AR)应用。作为该执行过程的一部分。该处理器1执行软件应用，以生成视频流。该处理器1可以通过基于eDP嵌入式显示端口标准的显示接口向时序控制器2发送视频流，该时序控制器2可以通过显示接口接收来自处理器1的视频流，并存储。
该视频流包括顺序排列的n个初始显示帧，n大于或等于2。各初始显示帧可以包括发光阶段S1和消隐阶段S2。该消隐阶段S2可以为垂直消隐(verticalblanking，V-blanking)阶段。n个初始显示帧的发光阶段S1的时间可以相同。
图1和图3中的视频流相同。在一实施方式中，如图1和图3所示，从第1个初始显示帧F1到第n个初始显示帧Fn，该初始显示帧的帧频依次减小，初始显示帧的消隐阶段S2的时间依次增大。具体地，在图1和图3中，第1个初始显示帧F1的帧频为144Hz，第2个初始显示帧F2的帧频为143Hz，第3个初始显示帧F3的帧频为142Hz，第n个初始显示帧Fn的帧频为115.2Hz。本公开所讲的帧频即为刷新率。从第1个初始显示帧F1到第n个初始显示帧Fn，各初始显示帧的发光阶段S1与2000H(像素行)对应。第1个初始显示帧F1的消隐阶段S2与208H对应，第2个初始显示帧F2的消隐阶段S2与223H对应(宽度W1对应15H)，第3个初始显示帧F3的消隐阶段S2与239H对应(宽度W2对应31H)，第n个初始显示帧Fn的消隐阶段 S2与760H对应。在图1中，亮度控制信号包括多个重复单元K1，一个重复单元K1对应管理552H。一个重复单元K1包括一个脉冲P和一个间隔段Q。在另一实施方式中，从第1个初始显示帧F1到第n个初始显示帧Fn，该初始显示帧的帧频依次增大，初始显示帧的消隐阶段S2的时间依次减小。
在步骤S20中，根据n个初始显示帧生成亮度控制信号以及n个修正显示帧(XF1、XF2、XF3…XFn)，n个修正显示帧(XF1、XF2、XF3…XFn)与n个初始显示帧(F1、F2、F3…Fn)对应；亮度控制信号为脉冲信号，且包括n个控制区段K，n个控制区段K与n个修正显示帧(XF1、XF2、XF3…XFn)对应。
从第1个初始显示帧F1到第n个初始显示帧Fn，以初始显示帧的帧频依次减小为例，从第2个修正显示帧XF2到第n个修正显示帧XFn，该修正显示帧的帧频相同，且第1个修正显示帧XF1的帧频大于第2个修正显示帧XF2的帧频。具体地，在图4中，第1个修正显示帧XF1的帧频为144Hz，第2个修正显示帧XF2到第n个修正显示帧XFn的帧频均为115.2Hz。从第1个修正显示帧XF1到第n个修正显示帧XFn，各修正显示帧的发光阶段S1与2000H(像素行)对应。第1个修正显示帧XF1的消隐阶段S2与208H对应，第2个修正显示帧XF2至第n个修正显示帧XFn的消隐阶段S2均与760H对应。
在图4中，亮度控制信号包括n个控制区段K，一个控制区段K可以包括多个重复单元K1，一个重复单元K1对应管理552H。一个重复单元K1包括一个脉冲P和一个间隔段Q。上述n个控制区段K的占空比可以相同。该占空比等于一个控制区段K中所有脉冲P的宽度的和与整个控制区段K的时间的比值。其中，该脉冲P的宽度指的是单个脉冲P所持续的时间。n个控制区段K的脉冲P的数量可以均为整数，例如4、5、6等。n个控制区段K中至少存在两个控制区段K的脉冲P的数量相同。
在一实施方式中，与第2个修正显示帧XF2至n个修正显示帧XFn对 应的(n-1)个控制区段K的脉冲P的数量相同；可选地，与第1个修正显示帧XF1和第2个修正显示帧XF2对应的控制区段K的脉冲P的数量不同。从第1个初始显示帧F1到第n个初始显示帧Fn，以初始显示帧的帧频依次减小为例，与第1个修正显示帧XF1对应的控制区段K的脉冲P的数量小于与第2个修正显示帧XF2对应的控制区段K中脉冲P的数量，例如，与第1个修正显示帧XF1对应的控制区段K的脉冲P的数量为4，与第2个修正显示帧XF2对应的控制区段K的脉冲P的数量为5；从第1个初始显示帧F1到第n个初始显示帧Fn，以初始显示帧的帧频依次增大为例，与第1个修正显示帧XF1对应的控制区段K的脉冲P的数量大于与第2个修正显示帧XF2对应的控制区段K中脉冲P的数量。
在另一实施方式中，从第1个初始显示帧F1到第n个初始显示帧Fn，初始显示帧的帧频依次减小，与第m个修正显示帧对应的控制区段K中脉冲P的数量等于与第1个修正显示帧XF1对应的控制区段K中脉冲P的数量，m大于等于3；与第m个修正显示帧对应的控制区段K中多个脉冲P的宽度相等，与第m个修正显示帧对应的控制区段K中脉冲P的宽度大于与第1个修正显示帧XF1对应的控制区段K中脉冲P的宽度，且两个脉冲P的宽度的差值为第一差值C0，第一差值C0同与第1个修正显示帧XF1对应的控制区段K中脉冲P的数量B0的乘积等于第(m-1)初始显示帧和第1初始显示帧F1中消隐阶段S2的差值E0，也就是说，C0*B0＝E0，其中，“*”表示乘法运算。具体地，在图5中，单个控制区段K中的多个脉冲P的宽度相等；与第1个修正显示帧XF1对应的控制区段K中的脉冲P的宽度W5等于与第2个修正显示帧XF2对应的控制区段K中的脉冲P的宽度W6，也就是说，在图5中，W5＝W6；与第3个修正显示帧XF3对应的控制区段K中的脉冲P宽度W7大于与第2个修正显示帧XF2对应的控制区段K中的脉冲P宽度W6，且两个脉冲P宽度的差值与脉冲P数量的乘积可以等于图1中的宽度W1，也就是说，在图5中，W7＞W6，且(W7-W6)*脉冲P数量＝W1；与第4个修正显示 帧XF4对应的控制区段K中的脉冲P宽度W8大于与第3个修正显示帧XF3对应的控制区段K中的脉冲P宽度W7，且两个脉冲P宽度的差值与脉冲P数量的乘积可以等于图1中的宽度W2，也就是说，在图5中，W8＞W7，且(W8-W7)*脉冲P数量＝W2；可知，在本实施方式中，本公开是将亮度控制信号由于帧频改变所多出的部分平均分配到下一个控制区段K的各个脉冲P中。
在又一实施方式中，从第1个初始显示帧F1到第n个初始显示帧Fn，初始显示帧的帧频依次减小，与第m个修正显示帧对应的控制区段K中脉冲P的数量等于与第1个修正显示帧XF1对应的控制区段K中脉冲P的数量，m大于等于3；在与第m个修正显示帧对应的控制区段K的多个脉冲P中，最后一个脉冲P的宽度大于其余任一脉冲P的宽度，且最后一个脉冲P的宽度与其余任一脉冲P的宽度的差值为第二差值；第二差值等于第(m-1)初始显示帧和第1初始显示帧F1中消隐阶段S2的差值。具体地，在图6中，与第1个修正显示帧XF1对应的控制区段K中的各个脉冲P的宽度相等，与第2个修正显示帧XF2对应的控制区段K中的各个脉冲P的宽度相等，与第1个修正显示帧XF1对应的控制区段K中的脉冲P宽度等于与第2个修正显示帧XF2对应的控制区段K中的脉冲P宽度；在与第3个修正显示帧XF3对应的控制区段K中，最后一个脉冲P除外，其余脉冲P的宽度等于与第2个修正显示帧XF2对应的控制区段K中的脉冲P的宽度；在与第3个修正显示帧XF3对应的控制区段K中，最后一个脉冲P的宽度W3大于其余脉冲P的宽度，其差值可以等于图1中的宽度W1；在与第4个修正显示帧XF4对应的控制区段K中，最后一个脉冲P除外，其余脉冲P的宽度等于与第2个修正显示帧XF2对应的控制区段K中的脉冲P的宽度；在与第4个修正显示帧XF4对应的控制区段K中，最后一个脉冲P的宽度W4大于其余脉冲P的宽度，其差值可以等于图1中的宽度W2；可知，在本实施方式中，本公开是将亮度控制信号由于帧频改变所多出的部分分配到下一个控制区段K的最后一 个脉冲P中。
在步骤S30中，将亮度控制信号与n个修正显示帧发送至显示面板3，以使显示面板3根据修正显示帧进行显示。
本公开实施方式的显示面板3可以包括驱动芯片301(Source IC)、像素电路303以及栅极驱动电路302。该像素电路303可以位于显示区内，并用于驱动显示面板3的发光元件进行显示。该栅极驱动电路302可以与像素电路303连接，用于向像素电路303发送扫描信号和亮度控制信号。该像素电路303以及栅极驱动电路302均与驱动芯片301连接。该时序控制器2用于将亮度控制信号和n个修正显示帧发送至驱动芯片301。该驱动芯片301根据该亮度控制信号向栅极驱动电路302发送控制信号，以使栅极驱动电路302向像素电路303发送扫描信号和亮度控制信号。该驱动芯片301用于将n个修正显示帧发送至像素电路303。该显示面板3用于根据修正显示帧进行显示。其中，上述显示面板3的发光亮度可以由与修正显示帧对应的控制区段K的占空比控制。在占空比相同时，其亮度可以相同。由于上述n个控制区段K的占空比可以相同，使得显示面板3的发光亮度可以相同，避免闪烁。
本公开实施方式还可以提供一种时序控制器2。该时序控制器2可以包括存储模块201、生成模块202以及发送模块203，其中：
该存储模块201用于接收并存储视频流，所述视频流包括顺序排列的n个初始显示帧，n大于或等于2，从第1个初始显示帧到第n个初始显示帧，初始显示帧的帧频依次增大或减小。其中，该存储模块201用于执行上述的步骤S10。
该生成模块202根据n个初始显示帧生成亮度控制信号以及n个修正显示帧，n个修正显示帧与n个初始显示帧对应；亮度控制信号为脉冲P信号，且包括n个控制区段K，n个控制区段K与n个修正显示帧对应。其中，该生成模块202用于执行上述的步骤S20。
该发送模块203将亮度控制信号与n个修正显示帧发送至显示面板3，以使显示面板3根据修正显示帧进行显示。其中，该发送模块203用于执行上述的步骤S30。
本公开实施方式还提供一种显示装置。该显示装置可以包括上述处理器1、上述显示面板3以及上述任一实施方式的时序控制器2。
本公开实施方式提供的显示装置、时序控制器及其控制方法属于同一发明构思，相关细节及有益效果的描述可互相参见，不再进行赘述。
以上仅是本公开的较佳实施方式而已，并非对本公开做任何形式上的限制，虽然本公开已以较佳实施方式揭露如上，然而并非用以限定本公开，任何熟悉本专业的技术人员，在不脱离本公开技术方案的范围内，当可利用上述揭示的技术内容做出些许更动或修饰为等同变化的等效实施方式，但凡是未脱离本公开技术方案的内容，依据本公开的技术实质对以上实施方式所作的任何简单修改、等同变化与修饰，均仍属于本公开技术方案的范围内。
