具体实施方式
这里将详细地对示例性实施例进行说明，其示例表示在附图中。下面的描述涉及附图时，除非另有表示，不同附图中的相同数字表示相同或相似的要素。以下示例性实施例中所描述的实施方式并不代表与本公开相一致的所有实施方式。
在将图像信号显示到显示屏的过程中，多个处理单元会对图像信号进行分工处理，例如第一处理单元对图像信号进行图像显示处理，第二处理单元对图像信号进行色彩亮度处理。相关技术中，由于进行色彩亮度的过程要比进行图像显示处理的过程时间要长，导致为图像切换时图像亮度的变化比图像显示的变化慢，呈现拖影现象。
基于上述问题，本公开实施例提出了一种图像信号传输方法，通过获取输入至时序控制器的图像信号，控制第一处理单元在第一时刻对图像信号进行第一处理，控制第二处理单元在第二时刻对图像信号进行第二处理，由于第一处理单元与第二处理单元处理同一图像信号的时刻不同，因此可以缩小第一处理单元将进行第一处理后的图像信号传输至第一面板和第二处理单元将进行第二处理后的图像信号传输至第二面板的时间差，从而改善了图像切换或者观看视频时人眼察觉到的拖影现象。
本公开实施例提供的图像信号传输方法可应用于各种显示屏系统中，如图1所示，显示屏包括时序控制器1、第一面板2和第二面板3。
时序控制器1用于接收待显示的图像信号；时序控制器1中包括第一处理单元11和第二处理单元12，第一处理单元11用于对输入至第一面板2的图像信号进行第一处理，第二处理单元12用于对输入至第二面板3的图像信号进行第二处理，进行第一处理所需的时长与进行第二处理所需的时长不同。
第一面板2用于接收第一处理单元进行第一处理后的图像信号，第二面板3用于接收第二处理单元进行第二处理后的图像信号。
下面以迷你LED(Mini-LED)显示屏为例进行介绍，Mini-LED显示屏主要由LCD显示面板和直下式的Mini-LED阵列背光面板组成，Mini-LED技术一般指的是将显示面板的大块背光面板分割成若干区域，每个区域都由单独的小尺寸Mini-LED芯片作为背光源。这种技术保留了LCD显示面板低成本、长寿命的优势，同时又能通过背光的分区控制实现高对比度和高动态范围显示。Mini-LED显示屏主要由LCD显示面板和直下式的Mini-LED阵列背光面板组成，如图2所示，背光面板被划分成多个区域，每个区域由若干个Mini-LED组成；在LCD显示面板显示不同图像时，背光面板的不同区域也会有不同的亮度，这种背光分区的方法相比传统LCD的整体背光能增加显示的对比度。相应的，与整体背光只需要打开和关闭相比，分区背光需要分别驱动和调节。
然而在背光面板上背光分区数较多、背光面板上Mini-LED排列不一定完全规则的情况下，分区算法复杂，所需的运算时间较长，导致输出给背光驱动的数据相比显示驱动的数据有一定延迟，表现为图像切换时背光亮度的变化比液晶偏转角的变化慢，有拖影现象。针对该问题，较好的解决方法是将分区算法模块从TCON芯片转移到算力更强的主板芯片上，并直接输出处理后的数据，但是主板芯片的开发周期长，目前也还没有明确的规划。
如图3所示，Mini-LED显示屏包括视频信号输入模块1、数据处理与控制模块2(相当于本公开实施例中的时序控制器)、显示驱动模块3、显示面板4(相当于本公开实施例中的第一面板)、背光驱动模块5以及背光面板6(相当于本公开实施例中的第二面板)。
其中，视频信号输入模块1主要用于接收外部的图像信号，并将接收到的信号输入到数据处理与控制模块2。
数据处理与控制模块2，主要实现数据格式的转换和算法的处理和实现。在本公开的一个实施例中，数据处理与控制模块2为一具有算法运算和数据处理能力的Tcon模块，具体包括：(1)数据编解码单元(也即第一处理单元)。该单元主要将视频信号输入模块1接收的数据信号转换为屏端驱动信号，输出到显示驱动模块3；(2)背光分区处理单元(也即第二处理单元)。该单元主要通过分区背光调节方法实现对各背光分区单元的亮度进行调整，并将调整后的背光驱动信号输出到背光驱动模块5，实现背光分区亮度的控制。
显示驱动模块3，该模块包括数据驱动单元和栅极驱动单元。数据驱动单元主要接收数据处理与控制模块2输出的编码后数据驱动信号，通过模数转换为面板的像素灰阶电压，驱动显示面板4显示；栅极驱动单元主要是接收数据处理与控制模块输出的扫描驱动控制信号，实现显示面板4像素开关的开启和关断，配合数据驱动模块实现一帧图像的显示和刷新。
显示面板4主要接收显示驱动模块3发送的驱动信号，显示面板4中的像素单元在像素灰阶电压和扫描驱动控制信号的作用下，实现图像不同灰阶的显示。显示面板4可为各种显示面板，诸如有机发光显示面板、液晶显示面板、等离子体显示面板、电泳显示面板、电润湿显示面板等。本公开实施例以液晶显示面板为例进行描述。
背光驱动模块5主要是接收数据处理与控制模块2计算得到的各分区背光数据驱动信号，从而动态调整各分区灯珠的驱动电流大小，实现各分区背光亮度的调节和输出。
背光面板6，该模块主要接收背光驱动模块5输出的电流，动态调节背光模组各分区LED灯珠亮度，实现背光分区亮度显示。背光面板6为由mini-LED灯珠组成的显示模组。该模组接收背光驱动模块5输出的PWM信号，从而调节不同分区mini-LED灯块的电流， 实现各分区背光亮度的调节。
上述Mini-LED显示屏可应用于大尺寸拼接显示屏、TV、笔记本、平板等中大尺寸显示场景中。
图4是根据一示例性实施例示出的一种图像信号传输方法的流程图，应用于如图1或图3所示的显示屏系统中，如图4所示，包括以下步骤：
在步骤S11中，获取输入至时序控制器的图像信号。
其中，时序控制器中包括第一处理单元和第二处理单元，第一处理单元用于对输入至第一面板的图像信号进行第一处理，第二处理单元用于对输入至第二面板的图像信号进行第二处理，进行第一处理所需的时长与进行第二处理所需的时长不同。
可选的，图像信号包括HDMI、DP等格式的视频流信号中的图像信号或单个图像信号。图像信号可以从任意具备图像信号获取，处理，以及发送功能的设备中获取，本实施例中如何获取图像信号不作限定。
在步骤S12中，控制第一处理单元在第一时刻对图像信号进行第一处理，并控制第二处理单元在第二时刻对图像信号进行第二处理。
可选的，若第一处理单元对图像信号进行第一处理的时长大于第二处理单元对图像信号进行第二处理的时长，则第一时刻早于第二时刻，也即第一处理单元对图像信号进行第一处理的时刻早于第二处理单元对图像信号进行第二处理的时刻。
若第一处理单元对图像信号进行第一处理的时长小于第二处理单元对图像信号进行第二处理的时长，则第一时刻晚于第二时刻，也即第一处理单元对图像信号进行第一处理的时刻晚于第二处理单元对图像信号进行第二处理的时刻。
在步骤S13中，将第一处理单元进行第一处理后的图像信号传输至第一面板，并将第二处理单元进行第二处理后的图像信号传输至第二面板。
本公开实施例通过获取输入至时序控制器的图像信号，控制第一处理单元在第一时刻对图像信号进行第一处理，控制第二处理单元在第二时刻对图像信号进行第二处理，由于第一处理单元与第二处理单元处理同一图像信号的时刻不同，因此可以缩小第一处理单元将进行第一处理后的图像信号传输至第一面板和第二处理单元将进行第二处理后的图像信号传输至第二面板的时间差，从而改善了图像切换或者观看视频时人眼察觉到的拖影现象。
在一些实施例中，第一面板为显示屏的背光面板，第二面板为显示屏的显示面板。
进一步的，第一面板为迷你LED显示屏驱动的背光面板，第二面板为LCD驱动的显示面板。
可选的，第一处理单元对图像信号进行的第一处理可以是分区算法处理，进而获取各个分区的分区系数，背光驱动模块根据分区系数控制背光面板中的某一个分区发光或者不发光。当背光面板划分为M*N个背光分区时，第一倍频信号对应地划分为M*N个图像分区，M为垂直方向的背光分区数，N是水平方向的背光分区数。
示例性的，图像信号被划分为2*2个图像分区：第一图像分区21、第二图像分区22、第三图像分区23和第四图像分区24，对应于每一个图像分区在背光面板中设置有一一对应的背光分区。对于每一个图像分区，其所对应的背光分区用于单独控制该图像分区的背光亮度。例如，假设第一图像分区21对应设置有第一背光分区11，第二图像分区22对应设置有第二背光分区12，第三图像分区23对应设置有第三背光分区13，第四图像分区24对应设置有第四背光分区14，则第一背光分区11用于单独控制第一图像分区21的背光亮度，第二背光分区12用于单独控制第二图像分区22的背光亮度，第三背光分区13用于单独控制第三图像分区23的背光亮度，第四背光分区14用于单独控制第四图像分区24的背光亮度，从而控制背光面板中不同分区的Mini-LED的发光强度。
第二处理单元对图像信号进行的第二处理可以是色彩算法、亮度补偿等处理，将处理后的图像信号发送给显示驱动模块，显示驱动模块控制液晶偏转角度，以使得显示面板显示图像。
如图5所示，由于Mini-LED显示屏中的背光分区处理单元对图像信号进行第一处理的时刻早于数据编解码单元进行第二处理的时刻，使得处理显示面板数据的算法模块开始较晚，输出给显示面板的数据也相当于有延迟，与进行背光算法的延迟相抵消，背光面板相对于背光面板的延迟也就大幅减小了。
在本公开实施例中，由于显示屏会在下一帧图像信号到来之前保持之前的状态，因此实际显示出来的图像仍然是原帧率。
在一些实施例中，步骤S12可具体实现为步骤S21-S22，具体如下：
在步骤S21中，对图像信号以帧为单位分别对每一帧图像信号进行设定次数的复制处理，得到目标图像信号。
其中，目标图像信号中的每一帧图像信号中包括数量与设定次数一致的图像帧。
示例性的，设定次数为2，如图6中的(a)所示，复制前的图像信号为4帧，则对图像信号中的4帧图像信号分别进行2次复制处理，如图6中的(b)所示，最终得到的目标图像信号中，第一帧图像信号中包括两个完全相同的图像帧，第二帧图像信号中包括两个完全相同的图像帧，以此类推。
作为一种可能的实现方式，确定进行第一处理所需的时长与进行第二处理所需的时长 之间的时间差，基于时间差确定设定次数，并对每一帧图像信号进行设定次数的复制处理。
应当理解的是，时间差越大，设定次数越大，示例性的，当时间差为2s时，设定次数为2；当时间差为4s时，设定次数为4。
作为另一种可能的实现方式，当第一面板为迷你LED显示屏驱动的背光面板，第二面板为LCD驱动的显示面板，由于背光面板上存在多个分区，通过对图像信号进行分区算法以控制背光面板上的各个分区显示亮度，因此设定次数还可以基于背光面板的分区数量确定，背光面板的分区越多，设定次数越大。
在步骤S22中，针对目标图像信号中的每一帧图像信号，拆分为第一图像帧和第二图像帧，控制第一处理单元在第一时刻对第一图像帧进行第一处理，并控制第二处理单元在第二时刻对第二图像帧进行第二处理。
示例性得，当设定次数为2时，由于目标图像信号中得每一帧信号都是依次发送得，因此第一图像帧为目标图像信号中帧图像信号中的奇数帧，第二图像帧为目标图像信号中帧图像信号中的偶数帧。
可选的，当第一图像帧和第二图像帧中包括的帧数不同时，例如第一图像帧包括2帧，第二图像帧包括1一帧，则将第一图像帧传输至第一处理单元时的第一频率不同于将第二图像帧传输至第二处理单元的第二频率。
应理解，每一帧图像信号的第一图像帧和第二图像帧处于相邻状态。
在本公开实施例中，对每一帧图像信号进行复制处理得到的目标图像信号中，每一帧图像信号的相邻帧携带的数据内容相同，将相同的图像帧分别传输至第一处理单元和第二处理单元，使得第一处理单元处理第一图像帧的时间不同于第二处理单元处理第二图像帧的时间，从而缩短时间差，减轻拖影现象。
需要说明的是，本领域内技术人员可以理解，本公开实施例上述涉及的各种实施方式/实施例中可以配合前述的实施例使用，也可以是独立使用。无论是单独使用还是配合前述的实施例一起使用，其实现原理类似。本公开实施中，部分实施例中是以一起使用的实施方式进行说明的。当然，本领域内技术人员可以理解，这样的举例说明并非对本公开实施例的限定。
基于相同的构思，本公开实施例还提供一种图像信号传输装置。
可以理解的是，本公开实施例提供的图像信号传输装置为了实现上述功能，其包含了执行各个功能相应的硬件结构和/或软件模块。结合本公开实施例中所公开的各示例的单元及算法步骤，本公开实施例能够以硬件或硬件和计算机软件的结合形式来实现。某个功能究竟以硬件还是计算机软件驱动硬件的方式来执行，取决于技术方案的特定应用和设计约 束条件。本领域技术人员可以对每个特定的应用来使用不同的方法来实现所描述的功能，但是这种实现不应认为超出本公开实施例的技术方案的范围。

进一步可以理解的是，术语“第一”、“第二”等用于描述各种信息，但这些信息不应限于这些术语。这些术语仅用来将同一类型的信息彼此区分开，并不表示特定的顺序或者重要程度。实际上，“第一”、“第二”等表述完全可以互换使用。例如，在不脱离本公开范围的情况下，第一信息也可以被称为第二信息，类似地，第二信息也可以被称为第一信息。
进一步可以理解的是，本公开实施例中尽管在附图中以特定的顺序描述操作，但是不应将其理解为要求按照所示的特定顺序或是串行顺序来执行这些操作，或是要求执行全部所示的操作以得到期望的结果。在特定环境中，多任务和并行处理可能是有利的。
本领域技术人员在考虑说明书及实践这里公开的发明后，将容易想到本公开的其它实施方案。本申请旨在涵盖本公开的任何变型、用途或者适应性变化，这些变型、用途或者适应性变化遵循本公开的一般性原理并包括本公开未公开的本技术领域中的公知常识或惯用技术手段。
应当理解的是，本公开并不局限于上面已经描述并在附图中示出的精确结构，并且可以在不脱离其范围进行各种修改和改变。本公开的范围仅由所附的权利范围来限制。
