图1为本申请实施例提供的一种显示设备的结构示意图。
如图1所示，所述显示器可以包括N个显示区域，且该N为大于或等于1的整数，本申请对该N的值并不进行限定。
上述第一控制系统可以包括：所述第一处理器，以及，N个第一控制模块。该N个第一控制模块与上述N个显示区域一一对应。其中，该N个第一控制模块可以串行连接，构成第一串行链路。该第一处理器可以与该第一串行链路中第1个第一控制模块的一端连接。上述每个第一控制模块还可以通过上述开关装置与对应显示区域中的显示器的显示组件(图1中未示出)连接。
在一些实施例中，该第一处理器例如可以为该显示设备的系统级芯片(System on Chip，SoC)，或者称为主板。以图1为例，其中第一控制模块1可以与显示区域1对应；第一控制模块2可以与显示区域2对应……第一控制模块N可以与显示区域N对应。如图1所示，第一处理器与第一控制模块1连接，则该N个第一控制模块串行连接构成第一串行链路中第1个第一控制模块可以为第一控制模块1。在一些实施例中，上述各显示区域中的显示器的显示组件可以为任意一种现有的显示组件，本申请对此并不进行限定。
上述第二控制系统可以包括：所述第二处理器，以及，N个第二控制模块。该N个第二控制模块 与上述N个显示区域一一对应。其中，该N个第二控制模块可以串行连接，构成第二串行链路。该第二处理器可以与该第二串行链路中第1个第二控制模块的一端连接。上述每个第二控制模块还可以通过上述开关装置与对应显示区域中的显示器的显示组件连接(图1中未示出)连接。
在一些实施例中，该第二处理器例如也可以为该显示设备的SoC。仍然以图1为例，其中第二控制模块N可以与显示区域1对应；第二控制模块N-1可以与显示区域2对应……第二控制模块1可以与显示区域N对应。如图1所示，第二处理器与第二控制模块1连接，则该N个第二控制模块串行连接构成第二串行链路中第1个第二控制模块可以为第二控制模块1。
上述第一串行链路中的第i个第一控制模块对应的显示区域，与第二串行链路中的第N-i+1个第二控制模块对应的显示区域为同一显示区域。其中，该i可以为大于或等于1，且小于N的整数。例如，如图1所示，第一控制模块2对应的显示区域，与第N-1个第二控制模块对应的显示区域为同一显示区域。
应理解，图1仅是对该显示设备的结构进行的示例性说明，本申请上述显示器的显示区域的划分方式并不进行限定。在一些实施例中，显示器的不同显示区域的大小可以相同，也可以不同。不同显示区域的形状可以相同，也可以不同，本申请对此并不进行限定。
上述第一控制系统可以作为该显示设备的主控制系统。第二控制系统可以作为该显示设备的从控制系统。第一控制系统中的每个第一控制模块均可以用于检测在该第一控制模块之后且相邻的第一控制模块是否存在异常。因为第一串行链路中第N个第一控制模块之后没有第一控制模块，因此，第一串行链路中的第i个第一控制模块可以用于检测第i+1个第一控制模块是否存在异常。如前述所说，该第i+1个第一控制模块为在该第i个第一控制模块之后且相邻的第一控制模块。在一些实施例中，如图1所示，以第一控制模块2为例，该第一控制模块2可以检测第一控制模块3是否存在异常。
在一些实施例中，上述“第i+1个第一控制模块是否存在异常”例如可以包括：该第i+1个第一控制模块自检是否正常、与该第i+1个第一控制模块连接的显示组件的自检是否正常，以及，该第i+1个第一控制模块对应的显示区域的图像显示是否正常等至少一项。
若上述第i+1个第一控制模块存在异常，则该第i个第一控制模块可以通过上述开关装置向第一处理器，以及，第二处理器发送“用于指示该第i+1个第一控制模块存在异常”的指示信息。
第一处理器可以响应该指示信息，控制“第一串行链路中第1个第一控制模块至第i个第一控制模块”对应的显示区域进行图像显示。
在一些实施例中，仍然以第i+1个第一控制模块为第一控制模块3为例，假定第一控制模块2确定该第一控制模块3存在异常，该第一控制模块2可以通过上述开关装置向上述第一处理器和第二处理器发送用于指示第一控制模块3存在异常的指示信息。然后，第一处理器可以响应该指示信息，通过第一控制模块1和第一控制模块2，控制第一控制模块1对应的显示区域和第一控制模块2对应的显示区域进行图像显示。
第二处理器可以响应该指示信息，控制第二串行链路中第1个第二控制模块至第N-i个第二控制模块对应的显示区域进行图像显示。也就是说，上述第1个第二控制模块至第N-i个第二控制模块对应的显示区域也就是除了第一处理器控制的显示区域之外的显示区域。
在一些实施例中，仍然以第i+1个第一控制模块为第一控制模块3为例，则上述第二串行链路中第1个第二控制模块至第N-i个第二控制模块为显示区域3-显示区域N对应的第二控制模块，例如第二控制模块1至第二控制模块N-2。因此，第二处理器可以响应该指示信息，通过第二控制模块1至第二控制模块N-2，控制第二控制模块1至第二控制模块N-2对应的显示区域进行图像显示。
在该示例下，第一控制模块3存在异常，则第一处理器控制第一控制模块1对应的显示区域和第一控制模块2对应的显示区域进行图像显示。第二处理器控制第二控制模块1至第二控制模块N-2对应的显示区域进行图像显示，以实现将上述显示器中除了“第一控制模块1对应的显示区域和第一控制模块2对应的显示区域”之外的显示区域补齐，保障了显示器的全局显示。
在本实施例中，显示设备可以包括：第一处理器，以及，N个第一控制模块、第二处理器，以及，N个第二控制模块，以及，开关装置。通过第i个第一控制模块，可以检测第i+1个第一控制模块是否存在异常，并在存在异常时，通过开关装置向第一处理器，以及，第二处理器发送用于指示该第i+1个第一控制模块存在异常的指示信息。然后，第一处理器可以控制“第1个第一控制模块至第i个第一控制模块”对应的显示区域进行图像显示，且第二处理器可以控制第1个第二控制模块至第N-i个第二控制模块对应的显示区域进行图像显示。通过上述方法，使得存在第一控制模块异常时，通过第一处理器以及第二处理器共同控制显示器进行全局显示，保障了显示器继续进行图像显示的同时，避免了进行模块化替换，本申请无需重新建立模块化的通信连接和端口，提高了恢复图像显示的效率，且保障了显示器全局恢复显示，提高了用户体验。
在一些实施例中，显示设备还可以进行控制系统的全局切换。
例如，上述第二处理器还可以在控制第二串行链路中第1个第二控制模块至第N-i个第二控制模块对应的显示区域进行图像显示之后，通过第二串行链路中第1个第二控制模块，检测第一串行链路中第N个第一控制模块是否接收到图像显示所需数据。
在一些实施例中，第二处理器例如可以向第二串行链路中第1个第二控制模块发送用于至于该第二控制模块对第一串行链路中第N个第一控制模块进行检测的指令。然后，该第二串行链路中第1个第二控制模块可以响应该指令，向第一串行链路中第N个第一控制模块发送检测指令，以使该第一控制模块反馈用于表征该第一控制模块是否接收到图像显示所需数据的检测结果。然后，该第二串行链路中第1个第二控制模块可以将该检测结果回传至第二处理器。第二处理器可以根据该检测结果，确定第一串行链路中第N个第一控制模块是否接收到图像显示所需数据。
若确定第一串行链路中第N个第一控制模块未接收到图像显示所需数据，说明上述第一控制系统中确实存在第一控制模块异常，导致上述该第一串行链路断开，进而导致第一处理器无法将图像显示所需数据下发至该第一串行链路中第N个第一控制模块。则第二处理器可以通过N个第二控制模块，控制N个显示区域进行图像显示。也就是说，第二处理器可以在确定上述第一控制系统存在第一控制模块异常时，直接通过该第二控制系统中的各第二控制模块，控制该显示器的全局显示。
若确定第一串行链路中第N个第一控制模块接收到图像显示所需数据，说明上述第一串行链路未断开。在一些实施例中，在该实现方式下，第一处理器可以继续控制第1个第一控制模块至第i个第一控制模块对应的显示区域进行图像显示，且第二处理器可以控制第1个第二控制模块至第N-i个第二控制模块对应的显示区域进行图像显示。
在本实施例中，第二处理器通过第二串行链路中第1个第二控制模块，检测第一串行链路中第N个第一控制模块是否接收到图像显示所需数据，并在确定第一串行链路中第N个第一控制模块未接收到图像显示所需数据时，确定第一控制系统中确实存在第一控制模块异常。然后，第二处理器可以通过该通过N个第二控制模块，控制N个显示区域进行图像显示，实现控制该显示器的全局显示。通过上述方法，在进行全局切换之前，排除了例如静电干扰等情况对第一控制系统是否出现异常的判断影响，提高了全局切换的准确性。通过全局切换来控制显示器显示，提高了显示器进行图像显示的准确性，提高了用户体验。
在一些实施例中，在全局替换之前，还可以删除第一控制模块对应显示区域中显示组件已经缓存的图像显示所需，以避免该显示组件根据已缓存的来自第一处理器的图像数据进行图像显示，进一步提高显示内容的准确性，提高了用户体验。
例如，以上述任一显示区域对应的显示组件包括至少一个驱动模块，且上述任一第一控制模块与对应显示区域中的至少一个驱动模块连接为例，第二处理器还可以在通过N个第二控制模块，控制N个显示区域进行图像显示之前，删除“第一串行链路中在第一串行链路中第1个第一控制模块至第i个第一控制模块”对应显示区域中的至少一个驱动模块缓存的图像显示所需数据。
在一些实施例中，以第i+1个第一控制模块为第一控制模块3为例，第一串行链路中在第i+1个第一控制模块之前的各第一控制模块，为第一控制模块1和第一控制模块2。也就是说，第二处理器还可以删除第一控制模块1和第一控制模块2对应显示区域中的至少一个驱动模块缓存的图像显示所需数据。
在一些实施例中，第二控制系统中的任一第二控制模块例如可以与对应显示区域中的至少一个驱动模块连接。在该实现方式下，第二处理器可以通过第一串行链路中在第i+1个第一控制模块之前的各第一控制模块对应显示区域对应的第二控制模块，该显示区域中的至少一个驱动模块发送缓存清除指令。相应的，该至少一个驱动模块可以响应该缓存清除指令，删除已缓存的图像显示所需数据。
应理解，本申请对上述显示组件中包括的至少一个驱动模块之间的连接关系并不进行限定。例如，该至少一个驱动模块可以串行连接。其中，第一控制模块可以与该串行连接的中第1个驱动模块连接，该串行连接的末端的驱动模块可以与显示器的灯板的连接。
在本实施例中，因为第一串行链路中第1个第一控制模块至第i个第一控制模块对应显示区域中的至少一个驱动模块缓存的图像显示所需数据，为第一处理器下发的图像显示所需数据。第二处理器通过先将该缓存的图像显示所需数据删除，在进行全局切换显示，避免了全局切换显示时，该第1个第一控制模块至第i个第一控制模块对应显示区域显示的为来自第一处理器的图像数据，保障了显示器全局均显示来自第二处理器的图像数据，保障了显示器全局显示的准确性，进一步提高了用户体验。
在一些实施例中，第一处理器还可以在上电之后，向各第一控制模块发送第一图像数据切分信息(也可以称为MAP)。其中，该第一图像数据切分信息用于使第一控制模块在接收到来自第一处理器的图像数据时，根据该第一图像数据切分信息，对该图像数据进行切分，得到该第一控制模块对应的图像子数据，并根据该图像子数据，控制该第一控制模块对应显示区域进行图像显示。
在一些实施例中，以N等于64、上述第一处理器为SOC1为例，图2为本申请提供的又一种显示设备的结构示意图。如图2所示，如图2中箭头所指顺序，可以为上述第一串行链路的始端到终端的方 向。每个第一控制模块可以在接收到上述第一图像数据切分信息之后，例如可以将该第一图像数据切分信息存储至该第一控制模块，以在后续使用时，从自身存储的数据中获取该第一图像数据切分信息。在各第一控制模块无异常时，第一处理器可以将图像数据按照如图2所示的顺序下发至各第一控制模块。然后，各第一控制模块，可以根据上述第一图像数据切分信息，从上述图像数据中获取该第一控制模块对应显示区域所需的图像子数据，并根据该图像子数据，控制该显示区域进行图像显示。
通过在上电之后，向各第一控制模块发送第一图像数据切分信息，使得各第一控制模块可以基于该图像数据切分信息，获取该第一控制模块对应显示区域进行图像显示所需的图像子数据，提高了图像显示的准确性。
在一些实施例中，第一处理器在上电之后，还可以对第一处理器进行自检，以及，向各第一控制模块发送检测指令，以使各第一控制模块进行自检。然后，第一处理器可以根据第一处理器的自检结果，以及，各第一控制模块的自检结果，确定是否通过第二处理器进行全局显示。
在一些实施例中，在一些实施例中，第一处理器还可以在上电之后，通过第一串行链路中第1个第一控制模块，向第二串行链路中第N个第二控制模块发送自检指令。通过发送该自检指令，使得第二处理器根据响应该自检指令进行自检。例如，以图1为例，第一处理器可以在上电之后，通过第一控制模块1向第二控制模块N发送自检指令。
在该实现方式下，相应的，第二处理器还可以在上电之后，通过第二串行链路中第N个第二控制模块接收上述自检指令。然后，第二处理器可以响应该自检指令，进行自检，以及，向各第二控制模块发送第二图像数据切分信息。
其中，该第二图像数据切分信息用于使第二控制模块在接收到来自第二处理器的图像数据时，根据该第二图像数据切分信息，对该图像数据进行切分，得到该第二控制模块对应的图像子数据，并根据该图像子数据，控制该第二控制模块对应显示区域进行图像显示。在一些实施例中，各第二控制模块在接收到上述第二图像数据切分信息之后，例如可以将该第二图像数据切分信息存储至该第二控制模块，以在后续使用时，从自身存储的数据中获取该第二图像数据切分信息。
在一些实施例中，以N等于64、上述第二处理器为SOC2为例，图5为本申请提供的又一种显示设备的结构示意图。如图3所示，如图3中箭头所指顺序，可以为上述第二串行链路的始端到终端的方向。每个第二控制模块可以在接收到上述第二图像数据切分信息之后，例如可以将该第二图像数据切分信息存储至该第二控制模块，以在后续使用时，从自身存储的数据中获取该第二图像数据切分信息。第二处理器可以将图像数据按照如图3所示的顺序下发至各第二控制模块。然后，各第二控制模块，可以根据上述第二图像数据切分信息，从上述图像数据中获取该第二控制模块对应显示区域所需的图像子数据，并根据该图像子数据，控制该显示区域进行图像显示。
在一些实施例中，上述第二串行链路中第N个第二控制模块例如可以在接收到来自第一串行链路中第1个第一控制模块的自检指令之后，通过P2P(一种现有的通信技术的名称)的方式，将该自检指令上传至第二处理器。
上述第一图像数据切分信息可以简称为MAP1(或者称为第一MAP图)，第二图像数据切分信息可以简称为MAP2(或者称为第二MAP图)。以上述图2和图3所示的显示设备为例，该MAP1和MAP2的构成差异例如可以如下所示：SOC1从右下定义为Controller1，左下定义为Controller64。而SOC2左下定义为Controller1，右下定义为Controller64。由于MAP1和MAP2的差异，因此，同一编号对应的第一控制模块和第二控制模块在图像取的位置不同，因此图像的获取内容上是不一样的。
应理解，本申请对第二处理器如何进行自检、第一处理器如何进行自检，以及，第一控制模块和第二控制模块如何进行自检均并不进行限定。
通过在接收到上述自检指令之后，向各第二控制模块发送第二图像数据切分信息，使得各第二控制模块可以基于该图像数据切分信息，获取该第二控制模块对应显示区域进行图像显示所需的图像子数据，提高了图像显示的准确性。
进一步的，在一些实施例中，若第二处理器未在预设时长内接受到上述自检指令，说明上述第一控制系统可能存在异常，例如第一处理器异常，或者，第一串行链路中第1个第一控制模块异常等导致该自检指令无法发出。因此，第二处理器还可以执行通过N个第二控制模块，控制N个显示区域进行图像显示的操作。
通过上述方法，第二处理器可以在未在预设时长内接受到上述自检指令时，直接进行全局切换，通过N个第二控制模块，控制N个显示区域进行图像显示，因此提高了全局切换的效率。

在一些实施例中，在第i+1个第一控制模块存在异常时，第i个第一控制模块可以控制该开关装置关断“第一串行链路中第i+1个第一控制模块至第N个第一控制模块与对应显示组件之间”的第一通道， 并通过第一串行链路中的第i-1个第一控制模块至第1个第一控制模块逐级向第一处理器发送上述指示信息。该第一控制模块可以控制该开关装置导通“第二串行链路中第1个第二控制模块至第N-i个第二控制模块与对应显示组件之间”的第二通道，并通过第二串行链路中第N-i个第二控制模块至第1个第二控制模块逐级向第二处理器发送上述指示信息。
在该实现方式下，在一些实施例中，该第一串行链路中的第一控制模块可以监测上述“第一串行链路中第i+1个第一控制模块至第N个第一控制模块与对应显示组件之间”的第一通道是否被关断，在该第一通道被关断之后，该第一串行链路中的第一控制模块可以向第一处理器发送上述“用于指示该第i+1个第一控制模块存在异常”的指示信息。

如图5所示，针对任一第一控制模块对应的显示区域，该显示区域的各驱动模块可以串行连接。该串行连接的一端(例如灯板1)可以与第一开关模块(例如开关(1-1))连接，该串行连接的另一端(例如灯板8)可以与第二开关模块(例如开关(1-2))连接。主板1(SOC1)可以接收外界给定的图像信号输入，然后，主板1可以将图像信号输出给Controller(1-1)，Controller(1-1)输出给Controller(1-2)，依次类推，直到输出给Controller(1-N)。
如图6所示，本申请实施例提供的一种图像显示方法的流程包括：
S601、SOC1上电；
S602、向各第一控制模块发送MAP1(也就是前述第一图像数据切分信息)。
S603、在输出图像信号的时候，可以在Vbyone信号的保留位上设定了图像的设定信号和全局状态监测指令(例如可以包括前述自检指令、通道切换指令、控制系统切换指令中的至少一项)。
SOC1还可以产生优先级最高的信号来中断硬件的上下电接口。
S604、Controller(1-1)可以向主板1回传全局监测信号；
如图5和图6所示，全局状态监测指令给到Controller(1-1)以后，Controller(1-1)可以通过P2P通道，以及，开关(1-1)将图像信号和全局状态监测指令一起给到Controller(1-1)连接的灯板1-灯板8上的驱动(Driver)模块。Controller(1-1)可以向主板1回传全局监测信号(可以包括所有第一控制模块对应显示区域的图像显示是否存在异常的检测结果)给主板1，设定为监测信号C11。
S605、SOC1可以根据上述全局监测信号，确定该第一控制系统是否存在异常(例如不同显示区域的画面显示是否同步、信号质量是否一致、第一控制系统中传输的指令状态是否正常等)。
S606、若异常，则SOC1可以拉低EN1(也就是关断上述第一通道)，切换到SOC2(也就是全局切换到第二控制系统进行全局控制)。
S607、若不存在异常，则SOC1继续控制显示器进行图像显示。
Controller(1-1)连接的灯板1-灯板8上的驱动(Driver)模块的监测信号(例如上述第一检测结 果)可以通过开关(1-2)回传Controller(1-1)，此监测信号可以定义为D11。
S608、Controller(1-1)可以通过P2P向与该Controller(1-1)连接的驱动模块发送检测指令。

其中，该驱动模块是否异常可以是指该显示区域对应的画面显示是否同步、信号质量是否一致、该驱动模块的指令状态是否正常等。
S611、SOC2上电；
S612、SOC2可以通过第二控制模块N监测EN1是否为高(也就是开关装置的电平是否为高)。
S613、若第二控制模块N确定EN1为高，则将该EN2为高的结果以P2P的方式回传至SOC2。
S614、SOC2向各第二控制模块发送MAP2(也就是前述第二图像数据切分信息)。
S615、系统自检时间是否超过T；
S616、若系统自检时间(指的是第一控制系统的自检时间)超过T，则SOC2可以确定EN1为高，且时间超过T，则自动切换到SOC2，实现对第二控制模块的自检，并根据自检结果判断是否继续控制显示器进行显示。对于信号的监测和传输，SOC1是从SOC1开始到Controller(1-1)，再到Controller(1-N)。而SOC2由于采用了反向串行模式，因此其监测的主体则由Controller(2-N)进行主导。由Controller(2-N)进行监测以后通过P2P回传到SOC2进行判断，然后SOC2可以按照正向的逻辑，Controller1，再到Controller(2-N)进行全局判断。SOC2判断以后再次完成系统的整体切换。
如图5所示，其中指向各开关的sel1和sel2可以用于表征：除了EN之外的指令。例如，sel1和sel2可以用于补充EN的全局指令传输不及时或者传输带宽不够时的就近传输。

若第一控制系统异常，则第一处理器可以确定该第一通道存在通信异常。然后，第一处理器可以向上述开关装置发送通道切换指令，以使该开关装置关断该第一通道，并导通上述第二通道。相应的，开关装置可以接收上述通道切换指令，并响应该通道切换指令，关断该第一通道，并导通上述第二通道。通过关断该第一通道，并导通上述第二通道，可以使得第二处理器在上述第一控制系统异常时，全局替换该第一控制系统，控制显示器进行图像显示。
在一些实施例中，显示设备还可以在开机过程中，进行开机自检，以进一步保障显示设备开机后可以正常进行图像显示。例如，第一处理器可以在显示设备开机初始化过程中，检测该第一控制系统是否无异常。在一些实施例中，第一处理器检测该第一控制系统是否无异常的具体实现方式，可以参照前述实施例所述的方法，在此不再赘述。
若第一处理器确定该第一控制系统无异常，则可以向上述第二处理器发送自检指令，以使该第二处理器检测第二控制系统是否无异常。也就是说，在第一控制系统自检无异常之后，可以指示第二控制系统进行自检，以使该显示设备完成两个控制系统的自检操作。
若第二处理器检测第二控制系统无异常，在一些实施例中，第二处理器例如可以向第一处理器反馈用于表征该第二控制系统无异常的自检结果，以使第一处理器知晓该第二控制系统无异常。然后，第一处理器可以控制显示器进行图像显示，并在确定上述第一控制系统存在异常时，切换至第二控制系统，通过第二处理器控制显示器进行图像显示。
若第二处理器检测第二控制系统存在异常，在一些实施例中，第二处理器例如可以向第一处理器反馈用于表征该第二控制系统存在异常的自检结果，以使第一处理器知晓该第二控制系统存在异常。然后，在一些实施例中，第一处理器例如可以通过上述显示器输出提示信息，以提示用户该第二控制系统存在异常。然后，第一处理器例如可以继续通过该第一控制装置，控制显示器进行图像显示。进一步的，在一些实施例中，第一处理器例如还可以在预设自检时长之后，再次向上述第二处理器发送自检指令，以使该第二处理器检测第二控制系统的异常是否恢复。
若第一处理器确定该第一控制系统存在异常，则可以向上述第二处理器发送“控制系统切换指令”，以使该第二处理器向上述开关装置发送通道切换指令，并控制显示器进行图像显示。第二处理器通过向上述开关装置发送通道切换指令，使得该开关装置可以响应该通道切换指令，关断第一通道，并导通第二通道，进而使得第二处理器可以控制显示器进行图像显示。
通过上述方法，使得显示设备在开机自检过程中，在确定第一控制系统存在异常时，切换至第二控制系统来控制显示器进行图像显示，进而使得显示设备在开机完成之后，即可进行图像显示，提高了用户体验。
进一步的，在一些实施例中，第二处理器例如还可以在接收到上述控制系统切换指令之后，控制上显示器显示用于提示用户上述第一控制系统存在异常的提示信息，以使用户知晓该第一控制系统存在异常，进一步提高了用户体验。
在一些实施例中，第二处理器还可以检测第一处理器是否存在异常。若第二处理器确定第一处理器存在异常，则可以确定上述第一通道存在通信异常。然后，第二处理器可以向上述开关装置发送通道切 换指令，以使该开关装置关断第一通道，导通第二通道。
若第二处理器确定第一处理器无异常，在一些实施例中，第二处理器可以仅保持与第一处理器之间的通信连接，以使第一处理器能够在第一控制系统异常时，向该第二处理器发送控制系统切换指令。
在一些实施例中，第二处理器例如可以通过是否在预设时长内接收到来自第一处理器的连接请求响应，确定该第一处理器是否存在异常。例如，第二处理器可以向上述第一处理器发送连接请求。然后，若第二处理器未在预设时长内接收到来自第一处理器的连接请求响应，说明第一处理器可能无法正常通信，则第二处理器可以确定该第一处理器存在异常。其中，上述预设时长例如可以为预先存储在该第二处理器中的。若第二处理器在预设时长内接收到来自第一处理器的连接请求响应，说明该第一处理器可以正常通信，则第二处理器可以确定该第一处理器无异常。
在一些实施例中，第二处理器可以周期性向上述第一处理器发送连接请求，并在每次发送连接请求之后，根据是否在预设时长内接收到来自第一处理器的连接请求响应，确定第一处理器是否存在异常。
通过上述方法，避免了第一处理器存在异常时可能无法向第二处理器发送控制系统切换指令，导致第二处理器无法及时控制显示器进行图像显示的问题(也就是避免了出现监测死循环)，通过第二处理器主动监测第一处理器是否存在异常，并在确定该第一处理器异常时，及时进行控制系统的切换，提高了切换显示设备的控制系统的效率，进一步提高了用户体验。
在一些实施例中，上述第一控制装置和第二控制装置均可以包括多个具有处理能力的控制模块，并基于该控制模块，确定各控制系统是否异常。在一些实施例中，图9为本申请提供的另一种显示设备的结构示意图。该显示设备的显示器可以包括N个显示区域(图9中未示出)。N为大于或等于1的整数。
如图9所示，上述第一控制装置可以包括：N个第一控制模块。其中，该N个第一控制模块与上述N个显示区域一一对应。该N个第一控制模块串行连接，且第一处理器与串行连接始端的第一控制模块(例如图9中所示的第一控制模块1)的第一端连接。上述每个第一控制模块还可以通过开关装置与对应显示区域中的显示器的显示组件(图9中未示出)连接。

在该实现方式下，针对任一第一控制模块，第一处理器可以通过该第一控制模块，控制与该第一控制模块连接的显示组件进行图像显示。
在一些实施例中，以显示目标图像为例，第一处理器例如可以先获取目标图像数据，然后将该目标图像数据发送至与该第一处理器连接的第一控制模块1。第一控制模块1还可以将该目标图像数据发送至第一控制模块2，以此类推，通过前述串行连接，直到第一控制模块N从第一控制模块N+1处，获取上述目标图像数据。然后，各第一控制模块可以根据该目标图像数据，控制与该第一控制模块连接的显示组件进行图像显示。
如前述所说，第一控制模块可以为具有处理能力的控制模块。在该实现方式下，在一些实施例中，针对任一第一控制模块，该第一控制模块可以获取“包括用于表征该第一控制模块对应显示区域的图像显示是否出现异常的检测结果”的第一异常检测结果，以及，“包括用于表征上述串行连接中，在该第一控制模块之后且相邻的第一控制模块是否存在异常的检测结果”的第二异常检测结果。
在一些实施例中，上述“图像显示是否出现异常”可以包括下述至少一项：该显示区域的显示亮度是否异常，以及，该显示区域的显示色度是否异常。
其中，上述显示区域的显示亮度是否异常例如可以是指该显示区域的显示亮度是否与其他显示区域的显示亮度一致，和/或，该显示区域的显示亮度是否在预设亮度范围内。例如，以“图像显示是否出现异常”包括：该显示区域的显示亮度是否异常为例，若该显示区域的显示亮度与其他显示区域的显示亮度不一致，和/或，该显示区域的显示亮度不在预设亮度范围内，则第一异常检测结果可以包括：用于表征该第一控制模块对应显示区域的图像显示出现异常的检测结果。若该显示区域的显示亮度是否与其他显示区域的显示亮度一致，且该显示区域的显示亮度在预设亮度范围内，则第一异常检测结果可以包括：用于表征该第一控制模块对应显示区域的图像显示无异常的检测结果。
其中，上述显示区域的显示色度是否异常例如可以是指该显示区域的显示色度是否与其他显示区域的显示色度一致，和/或，该显示区域的显示色度是否在预设色度范围内。例如，以“图像显示是否出现异常”包括：该显示区域的显示色度是否异常为例，若该显示区域的显示色度与其他显示区域的显示色度不一致，和/或，该显示区域的显示色度不在预设色度范围内，则第一异常检测结果可以包括：用于表征该第一控制模块对应显示区域的图像显示出现异常的检测结果。若该显示区域的显示色度是否与其他显示区域的显示色度一致，且该显示区域的显示色度在预设色度范围内，则第一异常检测结果可以包 括：用于表征该第一控制模块对应显示区域的图像显示无异常的检测结果。
在一些实施例中，上述“图像显示是否出现异常”例如还可以包括：该显示区域进行图像显示是否与其他显示区域同步。若该显示区域进行图像显示与其他显示区域同步，则上述第一异常检测结果可以包括：用于表征该第一控制模块对应显示区域的图像显示无异常的检测结果。若该显示区域进行图像显示与其他显示区域不同步，则上述第一异常检测结果可以包括：用于表征该第一控制模块对应显示区域的图像显示存在异常的检测结果。
应理解，本申请对上述第一控制模块如何获取该第一异常检测结果，并不进行限定。
在一些实施例中，以图9中的第一控制模块1为例，上述串行连接中，在该第一控制模块1之后且相邻的第一控制模块可以为：第一控制模块2。也就是说，该第一控制模块1可以获取“包括用于表征第一控制模块2是否存在异常的检测结果”的第二异常检测结果。以图9中的第一控制模块N为例，在上述串行连接中，没有在该第一控制模块N之后的第一控制模块。在该实现方式下，该第一控制模块N例如可以获取“包括用于表征该第一控制模块N是否存在异常的检测结果”的第二异常检测结果。
应理解，本申请对上述第一控制模块如何获取该第二异常检测结果，并不进行限定。例如，每个第一控制模块可以进行自检，并将用于表征该第一控制模块是否异常的自检结果，发送至串行连接中的上一级第一控制模块。例如，第一控制模块3可以进行自检，并将用于表征该第一控制模块3是否异常的自检结果发送至第一控制模块2，以使第一控制模块2获取上述第二检测结果。或者，仍然以第一控制模块2为例，该第一控制模块2可以在将上述目标图像数据发送至第一控制模块3之后，根据是否在预设响应时长内接收到来自该第一控制模块3的“用于表征已接收到该目标图像数据”的响应，确定该第一控制模块3是否异常。若第一控制模块2在预设响应时长内接收到来自该第一控制模块3的“用于表征已接收到该目标图像数据”的响应，则可以确定该第一控制模块3无异常。若第一控制模块3在预设响应时长内未接收到来自该第一控制模块3的“用于表征已接收到该目标图像数据”的响应，则可以确定该第一控制模块3存在异常。
然后，针对任一第一控制模块，该第一控制模块在根据上述第一异常检测结果和第二异常检测结果确定第一控制系统存在异常时，可以控制上述开关装置，关断上述第一通道，并向第二处理器发送控制系统切换指令。然后，第二处理器可以响应该控制系统切换指令，控制开关装置导通上述第二通道，并通过各第二控制模块，控制与各第二控制模块连接的显示组件进行图像显示。
在一些实施例中，第一控制模块例如可以在上述第一异常检测结果表征该第一控制模块对应显示区域的图像显示出现异常，和/或，第二异常检测结果表征上述串行连接中，在该第一控制模块之后且相邻的第一控制模块存在异常时，确定该第一控制系统存在异常。若上述第一异常检测结果表征该第一控制模块对应显示区域的图像显示无异常，且第二异常检测结果表征上述串行连接中，在该第一控制模块之后且相邻的第一控制模块无异常，则该第一控制模块可以确定第一控制系统无异常。
在一些实施例中，第一控制模块例如可以在确定第一控制系统存在异常时，向上述开关装置发送第一通道关闭指令。开关装置可以响应该第一通道关闭指令，关断上述第一通道。在一些实施例中，第二处理器例如响应上述控制系统切换指令，向上述开关装置发送第二通道导通指令，以使开关装置可以响应该第二通道导通指令，导通上述第二通道。
下面对上述开关装置进行详细说明：
图10为本申请提供的又一种显示设备的结构示意图。如图10所示，在一些实施例中，该开关装置可以包括：N个第一开关模块，以及，N个第二开关模块。其中，
上述N个第一控制模块与该N个第一开关模块一一对应，且N个第一控制模块与N个第二开关模块一一对应。针对任一第一控制模块，该第一控制模块，通过该第一控制模块对应的第一开关模块与对应显示区域中的显示器的显示组件连接，构成第一通道的发送子通道(图10中未示出)。该第一控制模块，通过该第一控制模块对应的第二开关模块与对应显示区域中的显示器的显示组件连接，构成第一通道的接收子通道(图10中未示出)。
在一些实施例中，以图10中的第一控制模块1为例，该第一控制模块1可以通过第一开关模块1，与对应显示区域中的显示器的显示组件连接，构成该第一控制模块1对应的第一通道的发送子通道。
上述N个第二控制模块与该N个第一开关模块一一对应，且N个第二控制模块与N个第二开关模块一一对应。针对任一第二控制模块，该第二控制模块，通过该第二控制模块对应的第一开关模块与对应显示区域中的显示器的显示组件连接，构成第二通道的发送子通道(图10中未示出)。该第二控制模块，通过该第二控制模块对应的第二开关模块与对应显示区域中的显示器的显示组件连接，构成第二通道的接收子通道(图10中未示出)。
在一些实施例中，以图10中的第二控制模块1为例，该第二控制模块1可以通过第一开关模块1，与对应显示区域中的显示器的显示组件连接，构成该第二控制模块1对应的第二通道的发送子通道。
在该实现方式下，针对任一第一控制模块，该第一控制模块可以通过上述第一通道的发送子通道， 控制与该第一控制模块连接的显示组件进行图像显示，以及，向该显示组件发送异常检测指令，以使该显示组件反馈第一异常检测结果。例如，第一控制模块可以通过上述第一通道的发送子通道，向与该第一控制模块连接的显示组件发送图像显示所需数据，以使该显示组件驱动显示器进行图像显示。在一些实施例中，显示组件获取上述第一异常检测结果的方式可以参照任意一种现有的确定显示器进行图像显示是否出现异常的方法，本申请在此不在赘述。
相应的，第一控制模块可以通过上述第一通道的接收子通道，接收来自该显示组件的第一异常检测结果。
在该实现方式下，针对任一第二控制模块，该第二控制模块可以在第一控制系统异常时，通过该第二通道的发送子通道，控制与该第二控制模块连接的显示组件进行图像显示，以及，向该显示组件发送异常检测指令，以使该显示组件反馈“用于表征该第二控制模块对应显示区域的图像显示是否出现异常”的第三异常检测结果。例如，第二控制模块可以通过上述第二通道的发送子通道，向与该第二控制模块连接的显示组件发送图像显示所需数据，以使该显示组件驱动显示器进行图像显示。在一些实施例中，该第三异常检测结果中所说的“显示区域的图像显示是否出现异常”可以参照前述实施例所述方法，在此不再赘述。
相应的，该第二控制模块可以通过该第二通道的接收子通道，接收来自该显示组件的第三异常检测结果。在一些实施例中，第二控制模块可以根据该第三异常检测结果，确定该第二控制系统是否存在异常。
在一些实施例中，进一步的，上述第二处理器还可以向每个第二控制模块发送同步时钟信号，以通过各第二控制模块，控制与各第二控制模块连接的显示组件同时进行图像显示。第二处理器通过向各第二控制模块发送上述同步时钟信号，使得各第二控制模块可以根据该同步时钟信号，控制与各第二控制模块连接的显示组件同时进行图像显示。通过上述方法，保障了显示器进行图像显示全局的同步性，进一步提高了用户体验。
以上述第一处理器为主板1、第二处理器为主板2、第一控制模块1为Controller(1-1)、第一控制模块2为Controller(1-2)…第一控制模块N为Controller(1-N)；第二控制模块1为Controller(2-1)、第二控制模块2为Controller(2-2)…第二控制模块N为Controller(2-N)；第一开关模块1为开关(1-1)、第一开关模块2为开关(2-1)…第一开关模块N为开关(N-1)；第二开关模块1为开关(1-2)、第二开关模块2为开关(2-2)…第二开关模块N为开关(N-2)为例，图11为本申请提供的又一种显示设备的结构示意图。基于如图11所示的显示设备，图12为本申请提供的一种图像显示方法的流程示意图。
如图11所示，其中，灯板指的是显示器的灯板(一个显示器可以包括多个灯板，图11是以上述N个显示区域中，每个显示区域包括8个灯板为例进行的示例性说明，本申请对一个显示区域包括的灯板的数量并不进行限定)。在一些实施例中，每个灯板可以对应至少一个显示组件(图11中未示出)。在一些实施例中，针对任一显示组件，该显示组件可以包括：至少一个驱动模块。
如图11所示，针对任一第一控制模块对应的显示区域，该显示区域的各驱动模块可以串行连接。该串行连接的一端(例如灯板1)可以与第一开关模块(例如开关(1-1))连接，该串行连接的另一端(例如灯板8)可以与第二开关模块(例如开关(1-2))连接。主板1(SOC1)可以接收外界给定的图像信号输入，然后，主板1可以将图像信号输出给Controller(1-1)，Controller(1-1)输出给Controller(1-2)，依次类推，直到输出给Controller(1-N)。
如图12所示，本申请实施例提供的另一种图像显示方法包括：
S1201、SOC1上电；
S1202、在输出图像信号的时候，可以在Vbyone信号的保留位上设定了图像的设定信号和全局状态监测指令(例如可以包括前述自检指令、通道切换指令、控制系统切换指令中的至少一项)。
SOC1还可以产生优先级最高的信号来中断硬件的上下电接口。
主板1除了在Vbyone的保留位上设定指令信号以外，还可以增加其他的指令通道，比如I2C总线相关指令，串行外设接口(Serial Peripheral Interface，SPI)指令等能够实现数据和指令的同步传输的指令通道。
S1203、Controller(1-1)可以向主板1回传全局监测信号；
如图11和图12所示，全局状态监测指令给到Controller(1-1)以后，Controller(1-1)可以通过P2P通道，以及，开关(1-1)将图像信号和全局状态监测指令一起给到Controller(1-1)连接的灯板1-灯板8上的驱动(Driver)模块。Controller(1-1)可以向主板1回传全局监测信号(可以包括所有第一控制模块对应显示区域的图像显示是否存在异常的检测结果)给主板1，设定为监测信号C11。
S1204、SOC1可以根据上述全局监测信号，确定该第一控制系统是否存在异常(例如不同显示区域的画面显示是否同步、信号质量是否一致、第一控制系统中传输的指令状态是否正常等)。
S1205、若异常，则SOC1可以拉低EN1(也就是关断上述第一通道)，切换到SOC2(也就是全局切换到第二控制系统进行全局控制)。
S1206、若不存在异常，SOC1继续控制显示器进行图像显示。
Controller(1-1)连接的灯板1-灯板8上的驱动(Driver)模块的监测信号(例如上述第一检测结果)可以通过开关(1-2)回传Controller(1-1)，此监测信号可以定义为D11。
S1207、Controller(1-1)可以通过P2P向与该Controller(1-1)连接的驱动模块发送检测指令。
S1208、各驱动模块可以自检；
各驱动模块可以在自检完成之后，向Controller(1-1)反馈检测结果。
S1209、Controller(1-1)可以将该表征驱动模块是否存在异常的检测结果反馈至SOC1。
其中，该驱动模块是否异常可以是指该显示区域对应的画面显示是否同步、信号质量是否一致、该驱动模块的指令状态是否正常等。
其中，C11和D11返回的时间和种类可以不一样。C11监控着整个显示区域的图像显示是否正常，同步是否正常，通信是否正常。D11监测的是该Controller(1-1)对应显示区域的灯板的图像显示是否正常、是否存在某一个灯板的某一个区块不正常的情况等。
当主板1与Controller(1-1)之间存在通信异常的时候，主板1将无法收到对应的C11，则主板1可以在预设时长内未接收到上述C11时，确定与Controller(1-1)之间存在通信异常。当主板1发送了全局状态监测指令以后，Controller(1-1)进行自检，确定自检通过以后发送C11，C11在主板1上进行锁存。若主板1与Controller(1-1)之间异常，则主板1输出全局切换指令(例如上述控制系统切换指令)EN1，实现对于开关(1-1)和开关(1-2)的控制，从而实现了系统的全局切换(具体实现参照前述实施例，不再赘述)。
当Controller(1-1)和Controller(1-2)之间存在问题时，其实现方式可以参照前述实施例和图11，在此不再赘述。以此类推，直到Controller n的全局监测完成，整个系统完成备份(指的是通过两个控制系统控制显示器进行图像显示，其中一个控制系统作为备份)自检工作。
S1210、SOC2上电；
S1211、SOC2可以监测EN1是否为高(也就是开关装置的电平是否为高)。
S1212、若EN1为高，则自动切换到SOC2，实现对第二控制模块的自检，并根据自检结果判断是否继续控制显示器进行显示。
S1213、判断系统自检时间是否超过T；
S1214、若系统自检时间(指的是第一控制系统的自检时间)超过T，则SOC2可以确定EN1为高，且时间超过T，则自动切换到SOC2，实现对第二控制模块的自检，并根据自检结果判断是否继续控制显示器进行显示。
如图11所示，其中指向各开关的sel1和sel2可以用于表征：除了EN之外的指令。例如，sel1和sel2可以用于补充EN的全局指令传输不及时或者传输带宽不够时的就近传输。
在本实施例中，当自检到主板1系统(第一控制系统)中存在问题的时候，无论是EN监测还是时间维度监测都将直接将系统切换到主板2系统(第二控制系统)。而不是模块化切换。这种切换能够有效避免系统的持续损伤和二次损坏。比如Controller损坏以后不工作，其出现短路或者损伤，导致漏电流过大，这样只是在系统中没有被显性的发现，因此会造成其他的模块，比如电源模块的损伤等。因此，通过上述方法，还提高了显示设备使用的安全性，且提高了器件的使用寿命。通过上述全局切换，还保障了显示器全局同步显示。全局切换以后，主板1系统可以进入休眠或者不工作状态，避免持续损伤。此外，通过在串行系统基础上采用前级系统备份实时启动的方式实现全局正向串行系统的同步显示切换，实现系统的高可靠性，保障了全局0延迟同步切换。且通过上述串行返回通道实时回传同步切换机制，保证了用户对该显示设备进行操作的操作信息可以同步系统回传，进而确保了任意时刻画面设置为用户诉求画面设置，进一步提高了用户体验。
本申请还提供了一种计算机可读的非易失性存储介质，该计算机可读的非易失性存储介质可以包括：U盘、移动硬盘、只读存储器(ROM，Read-Only Memory)、随机存取存储器(RAM，Random Access Memory)、磁盘或者光盘等各种可以存储程序代码的介质，具体的，该计算机可读的非易失性存储介质中存储有程序指令，程序指令用于上述实施例中的方法。
为了方便解释，已经结合具体的实施方式进行了上述说明。但是，上述示例性的讨论不是意图穷尽或者将实施方式限定到上述公开的具体形式。根据上述的教导，可以得到多种修改和变形。上述实施方式的选择和描述是为了更好的解释原理以及实际的应用，从而使得本领域技术人员更好的使用所述实施方式以及适于具体使用考虑的各种不同的变形的实施方式。
