具体实施方式
以下结合附图对本公开的具体实施方式进行详细说明。应当理解的是，此处所描述的具体实施方式仅用于说明和解释本公开，并不用于限制本公开。
第一方面，本公开提供一种拼接屏的显示控制方法，所述拼接屏包括多个子显示屏。图1为本公开实施例提供的拼接屏的显示控制方法的流程示意图，如图1所示，所述显示控制方法包括：
S11、根据时间码信号，以无线发送的方式向子显示屏发送显示控制信号；
S22、根据显示控制信号控制子显示屏的显示。
时间码信号用于指示当前的时间节点。显示控制信号用于控制子显示屏对其存储的显示内容进行相应的显示处理，以使多个子显示屏共同显示目标显示内容。
在本公开实施例中，拼接屏尤其适用于大型演出中。演出过程中，时间码信号可以由音控台的时间码生成装置生成。图2为本公开实施例提供的显示控制方法的应用场景示意图，如图1和图2所示，显示控制方法的步骤S11可以由显示控制装置1来执行，该显示控制装置1可以为无线信号基站，无线信号基站可通过广播来发送显示控制信号。广播的方式包括但不限于LoRa方式。时间码生成装置3向 显示控制装置1发送时间码信号，显示控制装置1根据时间码信号向各子显示屏20发送显示控制信号。
音控台可以与音源设备连接，音源设备提供与目标显示内容对应的音频信号。音控台接收音源设备提供的音频信号，通过其音源输出装置对接收到的音频信号进行处理并输出，同时，时间码生成装置3开始输出时间码信号，并在音频输出装置输出音频信号的过程中，时间码生成装置3以预定时间间隔持续生成并输出时间码信号。示例性地，在音控台接收到音源设备提供的音频信号的初始时刻，时间码生成装置3生成的时间码信号为“0”，之后，在音控台持续接收到音频信号的过程中，时间码生成装置3以预定时间间隔依次输出时间码信号“1”、“2”、“3”、“4”……，同时，音控台的音频输出装置输出处理后的音频信号。预定时间间隔可以为1ms或其他较短的时间间隔。
在步骤S11中，显示控制装置1可以根据时间码信号所指示的时间节点，向子显示屏20发送显示控制信号，从而使得拼接屏2所显示的目标显示内容与音控台所输出的音频信号同步。显示控制信号可以包括多种控制信号，不同种的控制信号可以控制子显示屏进行不同的显示处理。例如，显示控制信号可以为控制子显示屏开始进行显示放的控制信号；或者，显示控制信号可以为控制子显示屏停止显示的控制信号等等。
在实际演出过程中，时间码信号可以同时发送至显示控制装置1和光控装置中，光控装置可以根据时间码信号对舞台灯光进行控制，从而使得拼接屏显示的显示画面与舞台灯光、音控台所输出的音频信号同步。
在本公开实施例中，拼接屏2在进行显示时，各子显示屏不需要通过有线连接的方式获取显示内容数据，而且可以采用无线信号传输的方式控制每个子显示屏对其存储的显示内容进行显示，进而使得多个子显示屏拼接显示出完整的目标显示内容。通过本公开实施例提供的显示控制方法，各子显示屏无需连接信号线，从而提供了一种新型的拼接屏的显示控制方式。通过该显示控制方式，当拼接屏用于演 出过程中时，子显示屏可以作为演员手中的道具，在舞台中被随意移动，从而呈现出一种新型的表演方式。且在表演过程中，子显示屏不会因信号线故障而影响其显示效果，更为安全可靠。
显示控制装置1每次发送显示控制信号时，均可以通过两个频率(主用频率和备用频率)同时发送显示控制信号，以保证子显示屏可以接收到显示控制信号。
图3为本公开实施例提供的显示控制方法中步骤S11的可选方式流程图。例如，显示控制信号可以包括：起始显示控制信号。如图3所示，步骤S11可以包括以下步骤S11a至S11c。
S11a、当时间码信号指示当前的时间节点达到目标显示内容的开始显示节点时，向各子显示屏发送起始显示控制信号，起始显示控制信号用于控制子显示屏开始对其存储的显示内容进行显示。
目标显示内容的开始显示节点可以为目标显示内容开始显示时的理论时间节点，也可以为早于该理论时间节点、且与该理论时间节点间隔预设准备时间的时间节点。例如，时间码发送装置以一定的频率发送时间码信号，目标显示内容开始显示时的理论时间节点为时间码信号为“10”时所指示的时间节点，即，当时间码信号为“10”时，目标显示内容开始显示，同时音控台输出音频信号。这种情况下，可以在时间码信号为“10”时，向各子显示屏发送起始显示控制信号。而由于子显示屏从接收到起始显示控制信号到开始进行显示，可能需要一定的准备时间，因此，在实际操作中，也可以在时间码信号为“8”时，向各子显示屏发送起始显示控制信号。
在一些实施方式中，目标显示内容包括按时间轴分布的N个目标片段，每个子显示屏中存储的显示内容包括与N个目标片段一一对应的N个子片段，N为大于1的整数。即，在所有子显示屏同步显示第n个子片段时，拼接成目标显示内容的第n个目标片段，n为整数，0<n≤N。
在一些实施方式中，显示控制信号还可以包括：切换显示控制信号。该情况下，步骤S11还可以包括：
S11b、当时间码信号指示当前的时间节点达到第i个片段的显 示节点时，向各子显示屏发送切换显示控制信号。切换显示控制信号用于控制子显示屏开始显示其存储的第i个片段；其中，i为大于1且不大于N的整数。
在显示一定时间后，各子显示屏因其自身特性可能会出现显示不同步的现象，因此，可以在目标显示内容的预定(例如每个)目标片段的显示节点，向各子显示屏发送切换显示控制信号，从而控制各子显示屏开始显示相应的子片段，进而防止长时间显示后出现各子显示屏显示不同步的现象。
作为示例，可以在拼接屏开始显示一定时间后，以预定间隔在目标片段的显示节点，向各子显示屏发送切换显示控制信号，从而控制各子显示屏同步显示相应的子片段，即，可以不在每个目标片段的显示节点向各子显示屏发送切换显示控制信号，而每隔预定个数的目标片段，在一个目标片段的显示节点向各子显示屏发送切换显示控制信号。
在一些实施方式中，显示控制信号还可以包括：停止显示控制信号。该情况下，步骤S11还可以包括：
S11c、当时间码信号指示当前的时间节点达到目标显示内容的结束显示节点时，向各子显示屏发送停止显示控制信号，停止显示控制信号用于控制子显示屏停止显示，例如，可控制子显示屏不发光。
在一些实施方式中，显示控制信号还可以包括亮度调节信号，该情况下，步骤S11还可以包括：当时间码信号所指示的当前的时间节点达到预设的亮度调节节点时，向各子显示屏发送亮度调节信号。该亮度调节信号用于调节各子显示屏的亮度。亮度调节节点可以根据实际需要进行设置。
在一些实施方式中，显示控制方法还可以包括在步骤S11之前进行的：向各子显示屏下发显示内容。图4为本公开实施例提供显示控制方法中下发显示内容的过程示意图，如图4所示，下发显示内容的过程可包括如下步骤S01至S03。
S01、获取拼接屏待显示的目标显示内容。
目标显示内容可以根据表演过程中所需显示的内容和显示效果 预先制作。
S02、根据目标显示内容的分辨率、各子显示屏的分辨率、各子显示屏在拼接屏中的位置，确定各子显示屏待显示的显示内容。
S03、将各子显示屏待显示的显示内容下发至各子显示屏，以供各子显示屏对待显示的显示内容进行存储。
该步骤S03可以由显示内容开发平台来执行，待显示的显示内容可以通过运营商的4G/5G信号网络，并通过定制化的VPDN(Virtual Private Dial-up Networks，虚拟专用拨号网)发送至子显示屏。
在演出过程中，子显示屏可以由演员手持，子显示屏在拼接屏中的位置可不固定，而可以在预设的多个点位之间进行移动。因此，步骤S02中可以根据子显示屏对应的多个点位来确定子显示屏待显示的显示内容。在演出时，演员可以在适当时间在预设的多个点位之间行进，从而使子显示屏所显示的显示可以拼接成完整的目标显示内容。
另外，通过步骤S02确定每个子显示屏待显示的显示内容之后，可以将各子显示屏的ID号与子显示屏待显示的显示内容进行绑定。在步骤S03中，将显示内容下发至子显示屏中时，可以根据子显示屏的ID号与显示内容的对应关系，将待显示的显示内容准确地下发至相对应的子显示屏中。
另外，在将显示内容下发至子显示屏之前，还可以预先对拼接屏的各子显示屏的显示效果进行仿真，当仿真的显示效果达到预期目标后，再将各子显示屏待显示的显示内容下发至子显示屏中。
第二方面，本公开还提供一种拼接屏的显示控制设备，所述拼接屏包括多个子显示屏。所述显示控制设备包括显示控制装置，所述显示控制装置用于根据时间码信号，以无线发送的方式向各子显示屏发送显示控制信号。时间码信号用于指示当前的时间节点；显示控制信号用于控制各子显示屏对其存储的显示内容进行相应的显示处理，以使多个子显示屏共同显示目标显示内容。

信号发送模块13可以包括第一发送单元13a和第二发送单元13b，信号发送模块13每次发送控制信号时，均通过第一发送单元13a和第二发送单元13b同时进行信号发送，第一发送单元13a和第二发送单元13b以不同的频率同时发送控制信号。
