附图说明
为了更清楚地说明本公开或相关技术中的技术方案，下面将对实施例或相关技术描述中所需要使用的附图作一简单地介绍，显而易见地，下面描述中的附图是本公开的一些实施例而非所有可行的实施例，对于本领域普通技术人员来讲，在不付出创造性劳动的前提下，还可以根据这些附图获得其他的附图。

具体实施方式
为使本公开的目的、技术方案和优点更加清楚，下面将结合本公开实施例中的附图，对本公开实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例是本公开的一部分实施例，而不是全部的实施例。基于本公开中的实施例，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，都属于本公开保护的范围。
图1(a)和图1(b)为电视显示终端的信号处理的模块架构图。如图1(a)所示，该电视显示终端进行信号处理所涉及的模块包括液晶显示面板，并且包括时序控制器和源级驱动器。其中，时序控制器为信号发生端，用于根据接收到的图像信号生成并输出高速传输信号、时序控制信号以及锁频信号等数据驱动信号。源级驱动器用于从时序控制器接收数据驱动信号，对接收到的数据驱动信号中的高速传输信号进行图像数据到灰阶数据的转换等处理后，驱动显示面板中对应的显示区域。如图1(b)所示，电视显示终端中包括至少两个源级驱动器，该至少两个源级驱动器分别为显示面板的至少两个显示区域提供数据驱动信号。
在一些实施例中，源级驱动器的个数可以为12个。12个源级驱动器分别从时序控制器接收数据驱动信号。需要说明的是，时序控制器持续生成待传输的数据驱动信号并并行发送给每个源极驱动器，不同源级驱动器接收的数据驱动信号不同。
图2为源级驱动器的启动时序控制示意图，如图2所示，ISP数据为高速传输信号，EOL为数据的截止，ISTB为源级驱动器的时序控制信号，A为ISTB信号上升沿到EOL的时间，用来控制每一个源级驱动器的开始启动时间，其中开始启动的时间是 开始将图像数据转换为灰阶数据的时间。
在相关技术中，为了实现各列像素的同时驱动，每个源极驱动器均被设置为在收到数据信号的预定时间后启动数据驱动信号的转换工作，在一种实施例中，收到数据信号可以以数据信号中的EOL字段为标识，预定时间可以是预定时间A，每个源级驱动器对应的A都是相同的，时序控制器发送数据驱动信号后，至少两个源级驱动器在驱动每一行数据时都会同时启动图像数据到灰阶数据的转换工作，并行驱动显示面板中对应的显示区域，其中，显示面板以行为单位进行数据显示。
图4为相关技术中的信号传输示例图。如图4所示，电视显示终端中包括12个源级驱动器，各源级驱动器同时启动灰阶转换工作以驱动显示面板中对应的显示区域，使得显示面板进行数据显示。
由于至少两个源级驱动器同时启动灰阶转换工作，使得作为骚扰源的源级驱动器瞬间能量变得很大，进而使得辐射源瞬态能量超标，造成较强的电磁干扰。
在相关技术中，可以基于物理特性来抑制骚扰源，例如，在电子设备中增加屏蔽部件，用来抑制骚扰源。或者，可以通过削弱骚扰源的能力来抑制骚扰源。
然而，如果采用基于物理特性的方法，会导致电子设备的生产成本增加，如果采用削弱骚扰源能力的方法，会导致电子设备的稳定性降低。
本公开提供了一种信号处理方法、显示装置及终端，时序控制器生成待传输数据驱动信号，并按照预设时间间隔向至少两个源级驱动器发送数据驱动信号，从而避免出现至少两个源级驱动器同时启动灰阶转换工作所产生的辐射干扰过大的问题，从而能够有效抑制骚扰源的电磁干扰而不会增加电子设备的生产成本或降低电子设备的稳定性。
需要说明的是，本公开所述的方法适用于电视显示终端，例如电视等。为便于理解，本公开的以下实施例以图1所述的模块架构为例来说明本公开的技术方案，但是，显然，这并不能作为对本公开的限制，本公开所述的方法同样可以应用于模块架构为其他架构的电视显示终端中。
图3为本公开的一些实施例提供的用于显示装置的数据驱动信号的处理方法的流程示意图，该方法的执行主体为电视显示终端，该电视显示终端包括显示装置，所述显示装置包括时序控制器、第一源极驱动器和第二源极驱动器。在一些实施例中，该方法的执行主体可以为生成信号以及控制信号时序的模块，例如上述图1中的时序控制器。如图3所示，该方法包括：
S301：时序控制器根据接收到的图像信号生成待传输的数据驱动信号。
以上述图1所示的模块架构为例，由时序控制器作为信号发生端，生成待传输的数据驱动信号。
S302、时序控制器以预设时间间隔向至少两个源极驱动器发送所述数据驱动信号。
S303、所述至少两个源极驱动器分别在完成各自对应的所述数据驱动信号的接收后的第一时长启动灰阶转换进程。
其中，所述灰阶转换进程是图像数据到灰阶数据的转换工作。
在一些实施例中，所述至少两个源极驱动器中的所述灰阶转换进程持续的时长相同，从而，所述至少两个源级驱动器用于驱动对应显示区域的启动时间错开。
当时序控制器根据接收到的图像信号生成待传输的数据驱动信号之后，以预设时间间隔分别向所述至少两个源极驱动器发送所述数据驱动信号，所述至少两个源级驱动器在完成各自的灰阶转换进程后，再按照接收数据驱动信号的顺序驱动显示装置中对应的区域。
例如，在一些实施例中，时序控制器以预设时间间隔分别向所述至少两个源极驱动器发送所述数据驱动信号具体为时序控制器在第1秒向第一源级驱动器发送第一数据驱动信号，在第2秒向第二源级驱动器发送第二数据驱动信号，以此类推。经过这样的处理，每个源级驱动器接收数据驱动信号的时间不同，并且由于所述至少两个源极驱动器中的所述灰阶转换进程持续的时长相同，进而，用于驱动对应显示区域的启动时间也不同，即，使得各源级驱动器的用于驱动对应显示区域的启动时间可以错开。在一些实施例中，预设时间间隔可以根据液晶面板的需求设置，不受上述示例的限制。
在另一些实施例中，如图5所示，图5为本公开的一些实施例中的信号传输示例图，中间的源级驱动器首先接收到数据驱动信号，两侧的源级驱动器再依次接收数据驱动信号。各源级驱动器在完成各自的数据驱动信号的接收后的第一时长启动灰阶转换进程，然后驱动显示装置中对应的显示区域，从而使得显示装置进行数据的显示。
例如，在一些实施例中，所述显示装置包括第一源级驱动器、第二源级驱动器、第三源级驱动器和第四源级驱动器，并且第一源级驱动器、第二源级驱动器、第三源级驱动器和第四源级驱动器中的灰阶转换进程持续的时长相同。
所述时序控制器根据接收到的所述图像信号生成第一数据驱动信号、第二数据驱动信号、第三数据驱动信号和第四数据驱动信号。
在一些实施例中，所述时序控制器以所述预设时间间隔分别向所述第一源极驱动器发送所述第一数据驱动信号，向所述第二源极驱动器发送所述第二数据驱动信号，向所述第三源极驱动器发送所述第三数据驱动信号，向所述第四源极驱动器发送所述第四数据驱动信号，其中所述第一数据驱动信号，所述第二数据驱动信号，所述第三数据驱动信号，所述第四数据驱动信号，两两之间存在预设时间间隔。
在一些实施例中，所述向所述第三源极驱动器发送所述第三数据驱动信号的时刻与向所述第一源极驱动器发送所述第一数据驱动信号的时刻相同，所述向所述第四源极驱动器发送所述第四数据驱动信号与向所述第二源极驱动器发送所述第二数据驱动信号的时刻相同，其中，向所述第一源极驱动器发送所述第一数据驱动信号的时刻与向所述第二源极驱动器发送所述第二数据驱动信号的时刻呈预设时间间隔。
所述第一源极驱动器和所述第三源极驱动器沿所述显示装置的纵向对称轴对称地设置，所述第二源极驱动器和所述第四源极驱动器沿所述显示装置的所述纵向对称轴对称地设置。
所述第一源极驱动器和所述纵向对称轴的距离小于所述第二源极驱动器和所述对称轴的距离，所述向所述第一源极驱动器发送所述第一数据驱动信号的时刻早于向所述第二源极驱动器发送所述第二数据驱动信号。
在本公开的这些实施例中，时序控制器生成待传输的数据驱动信号，并以预设时间间隔向至少两个源级驱动器发送数据驱动信号，使得作为骚扰源的至少两个源级驱动器在完成各自的数据驱动信号的接收后的第一时长后分别启动灰阶转换进程，从而 避免出现至少两个源级驱动器同时启动转换工作所产生的辐射干扰过大的问题，从而能够有效抑制骚扰源的电磁干扰而不会增加电子设备的生产成本或降低电子设备的稳定性。
在另一些实施例中，如图6所示，图6为本公开的另一些实施例提供的用于显示装置中时序控制器向至少两个源级驱动器提供驱动信号传输方法的流程示意图，上述步骤S302包括：
S601、在第一时刻向第一源级驱动器发送第一数据驱动信号；
S602、在第二时刻向第二源级驱动器发送第二数据驱动信号。
其中，所述第二时刻为所述第一时刻之后的时刻，所述第二时刻与所述第一时刻间隔预设时间间隔。
上述步骤S303包括：
所述第一源极驱动器在完成所述第一数据驱动信号的接收后的第一时长启动第一灰阶转换进程；
所述第二源极驱动器在完成所述第二数据驱动信号的接收后的所述第一时长启动第二灰阶转换进程。
在一些实施例中，为使得液晶显示面板的各区域同时进行数据显示，所述第一源极驱动器中的所述第一灰阶转换进程持续的时长大于第二源极驱动器中的所述第二灰阶转换进程持续的时长，所述第一源极驱动器中的所述第一灰阶转换进程持续的时长与第二源极驱动器中的所述第二灰阶转换进程持续的时长之差和所述预设时间间隔相等，从而第一源级驱动器和第二源级驱动器可以同时驱动显示装置中对应的显示区域，从而使得显示装置进行数据的显示。即，使开始灰阶转换工作较早的源极驱动器的灰阶转换时间比开始灰阶转换工作较晚的源极驱动器的灰阶转换时间长，使得所有的源极驱动器同时结束灰阶转换进程，进而实现液晶显示面板的各区域同时进行数据显示。源极驱动器开始灰阶转换的时刻被设定在接收完数据驱动信号后的第一时长，通过ISTB信号的电平上升沿控制，灰阶转换工作结束的时刻可以通过ISTB信号的电平下降沿进行控制。
在一些实施例中，所述显示装置还包括液晶分子矩阵；
所述处理方法还包括所述至少两个源极驱动器在所述灰阶转换进程结束后向所述液晶分子矩阵输出灰阶电压，所述灰阶电压和所述数据驱动信号相对应。
在一些实施例中，所述时序控制器以预设时间间隔向至少两个源极驱动器发送所述数据驱动信号，从而所述时序控制器以设置有预设时间间隔的预设发送时序向所述至少两个源极驱动器发送所述数据驱动信号，所述预设发送时序与所述至少两个源级驱动器的标识具有预设对应关系。
在一些实施例中，可以预先建立发送时序与源级驱动器的标识的对应关系。
在一些实施例中，所述源级驱动器的标识可以是源级驱动器的编号。
在一些实施例中，假设电视显示终端中有12个源级驱动器，则可以预先建立下述表1所示的发送时序与源级驱动器的标识的对应关系。

第1毫秒 6,7
第2毫秒 5,8

即，时序控制器会在第1毫秒向第6和第7个源级驱动器发送数据驱动信号，在第2毫秒向第5和第8个源级驱动器发送数据驱动信号，以此类推。
在上述实施例的基础上，本公开的一些实施例涉及发送数据驱动信号的具体过程。

在又一些实施例中，在第1毫秒向第6个源级驱动器和第7个源级驱动器发送数据驱动信号，在第2毫秒向第5个源级驱动器和第8个源级驱动器发送数据驱动信号，在第3毫秒向第4个源级驱动器和第9个源级驱动器发送数据驱动信号，在各个小组内依次向远离对称轴的方向类推。
