可选地，由于type-C线材即能够进行电能传输又能够进行信号传输，因此，在本申请实施例中，可以使用type-C线材作为电源信号共用传输线以与电源信号共用输入接插件连接。在相关技术中，LED模组上使用具有26个针脚的接口进行信号传输，使用具有4个针脚的接口进行电能传输，而type-C接口仅有24个针脚，因此在本实施例中，每个复用针脚与至少两个LED灯板上的控制电路连接，将无需同时工作的不同的控制电路连接在同一个复用针脚上，实现针脚的复用，即使针脚的数量减少了，仍能够满足LED显示模组正常显示的需求。
需要说明的是，LED显示模组中的每个控制电路仅与一个复用针脚连接。
步骤S204，通过复用针脚分别将一一对应的第一信号传输至第一子电路。第一子电路接收到第一信号后，可以根据第一信号驱动自身工作。
作为一种可选的实施例，信号传输方法中还可以包括如下步骤：获取与复用针脚一一对应的第二信号，其中，每个第二信号分别用于驱动对应的复用针脚连接的上述至少两个控制电路中的第二子电路，且第二子电路与第一子电路不同；通过复用针脚分别将一一对应的第二信号传输至第二子电路。
LED控制装置可以在不同时刻下通过同一个复用针脚向LED灯板传输不同的信号，不同的信号用于驱动该复用针脚对应的不同的控制电路。通过上述步骤，采用针脚复用的方式，控制电源信号共用输入接插件上的复用针脚分别为LED灯板中的至少两个控制电路提供信号，由同一个复用针脚分别在不同时刻将对应的不同控制电路所需要的信号传输至LED显示模组中的LED灯板，达到减少了驱动LED显示模组所需要的线路的数目的目的，从而实现了简化LED显示模组所需配线的技术效果，进而解决了相关技术中驱动LED显示模组的线路较为复杂的技术问题。
作为一种可选的实施例，获取与复用针脚一一对应的第二信号，可以包括如下步骤：接收切换指令，其中，切换指令用于指示由通过复用针脚传输第一信号切换为通过复用针脚传输第二信号；响应切换指令，获取与复用针脚一一对应的第二信号。
本实施例中，切换指令可以用于改变LED显示模组的工作模式。为了改变LED显示模组的工作模式，切换指令改变LED控制装置通过复用针脚向LED灯板发送的信号的类型，通过不同的信号类型驱动LED灯板中的不同控制电路，实现对LED显示模组中灯板的工作模式的改变。
作为一种可选的实施例，切换指令可以包括校正指令，其中，校正指令用于指示由通过复用针脚传输显示信号切换为通过复用针脚传输校正电路驱动信号，其中，第一信号包括显示信号，第二信号包括校正电路驱动信号。
通过校正指令，可以指示LED显示模组由显示状态切换为校正状态，该状态切换过程中用于传输显示信号的复用针脚可以停止传输显示信号，并将其切换为传输用于驱动校正电路的校正电路驱动信号，使得不需要在LED控制装置和LED模组之间添加额外的线材即可完成多种类型信号的传输。
作为一种可选的实施例，切换指令可以包括显示指令，其中，显示指令用于指示由通过复用针脚传输校正电路驱动信号切换为通过复用针脚传输显示信号，其中，第一信号包括校正电路驱动信号，第二信号包括显示信号。
通过显示指令，可以指示LED显示模组由校正状态切换为显示状态，该状态切换过程中用于传输校正电路驱动信号的复用针脚可以停止传输校正电路驱动信号，并将其切换为传输用于控制显示模组中的灯珠显示图像的显示信号，使得不需要在LED控制装置和LED模组之间添加额外的线材即可完成多种类型信号的传输。
作为一种可选的实施例，切换指令还可以包括加密通讯指令，其中，显示指令用于指示由通过复用针脚传输加密通讯信号切换为通过复用针脚传输显示信号，其中，第一信号包括加密通讯信号，第二信号包括显示信号。
可选地，加密通讯指令可以用于LED显示模组和LED控制装置之间进行匹配校验。例如，LED显示模组中的MCU可以校验本次接入的LED控制装置是否与其型号匹配，或者是否为同一厂家出厂的设备，如果没有通过匹配校验，则拒绝与本次接入的LED控制装置建立连接并响应工作。此时，LED控制装置可以先通过第一信号与LED显示模组中的加密电路进行通讯，在彼此校验身份之后，生成加密通讯指令，通过该指令指示LED控制装置切换为正常工作模式，向LED灯板发送显示信号即可。
可选地，LED显示模组上电后，模组上具有单独的MCU，LED控制装置可以通过加密通讯信号对应的复用针脚向MCU传输加密通讯信号，MCU响应该信号后生成加密后的密钥并发送给LED控制装置。LED控制装置解出结果后，通过该复用针脚将结果返回MCU，MCU基于结果确定该控制盒是否为与LED显示模组相匹配的LED控制装置。如果匹配成功，MCU可以向LED控制装置反馈，LED控制装置据此生成加密通讯指令，指示将上述复用针脚中传输的信号由第一信号切换为第二信号，改变该复用针脚的用途。
需要说明的是，在本实施例中，校正电路仅在LED显示装置的调试阶段工作，且一般LED显示装置只需要进行一次调试即可，无需每一次显示之前均进行调试；而加密电路则是在每一次显示之前都会工作，LED显示装置上电之后，加密电路会先工作，只有通讯成功之后，LED显示装置才会正常显示画面。
图3是根据本申请可选实施例提供的电源信号共用输入接插件复用针脚的接线示意图，如图3所示，多个复用针脚可以为图中的针脚9、针脚10、针脚11和针脚12，每个复用针脚可以分别用于连接LED显示模组的校正电路和显示电路，且每个复用针脚负责连接的校正电路和显示电路并联设置。其中，复用针脚可以用于向显示电路传输列显示信号(DATA数据)，不同复用针脚对应连接的不同显示电路控制LED灯板上不同的显示区域。具体地，在LED显示装置的安装调试阶段，可以对每个LED显示模组的显示进行校正，在调试阶段，通过上位机或者控制软件手动触发，使得校正电路工作，此时显示电路传输低电平，即显示电路控制的显示区域不发光；完成校正之后，通过复用针脚向显示电路传输显示信号使得显示电路工作，恢复其传输显示数据的功能。
可选地，在本可选实施例中，校正电路可以包括逻辑时序信号译码电路，校正电路驱动信号可以包括行显示信号。在LED显示模组正常工作之前可以由LED控制装置通过向复用针脚传输何种信号来选择使LED显示模组中的显示电路或者逻辑时序 信号译码电路工作。
如图3所示，在本可选实施例中，复用针脚10还可以同时对应LED显示模组中的显示电路、校正电路和加密电路，显示电路、校正电路和加密电路并联设置并与复用针脚10连接。其中，复用针脚10对应的显示电路传输列显示信号(DATA数据)，加密电路工作时LED显示模组内的MCU(微控制单元)通过加密电路与LED控制装置内接收卡的MCU做通讯，只有通讯成功，LED显示模组才能正常显示，匹配成功之后加密电路停止工作，显示电路工作，恢复其传输显示数据(DATA)的功能；如果通讯不成功，则说明LED控制装置内的系统与LED显示模组未匹配成功，则需要更换系统。需要说明的是，在本实施例中，
在本可选实施例中，除了上述的4个针脚之外，电源信号共用输入电源信号共用输入接插件内的其余针脚均只与一个子电路连接，且这些子电路均为本领域的常规电路。具体地，如图3所示，1号、2号、3号、4号针脚与电源电路VCC电路连接；21号、22号、23号、24号针脚与电源电路GND电路连接；5号、6号、7号、8号针脚与显示电路连接；13号、14号、15号针脚与逻辑时序信号译码电路连接，17号、18号针脚与校正电路连接，16号、19号、20号针脚与逻辑时序信号电路连接。
图4是根据本申请可选实施例提供的上位机校正窗口的示意图，如图4所示，当用户操作上位机对LED显示模组进行校正时，可以通过校正窗口发出校正指令，校正指令用于指示由通过复用针脚传输显示信号切换为通过复用针脚传输校正电路驱动信号。LED控制装置接收到该校正指令后，切换复用针脚的用途，将复用针脚中传输的信号数据由显示信号切换为校正电路驱动信号，以驱动LED显示模组中的校正电路进行校正工作。
图5是根据本申请可选实施例提供的LED显示模组信号处理芯片的示意图，如图5所示，LED显示模组中至少具有U9、U10和U11三块信号处理芯片，三块信号处理芯片分别连接三路复用针脚，用于对不同复用针脚传输过来的信号进行放大和稳定波形。可选地，通过三块不同信号处理芯片放大后可以输出三个处理后信号，处理后信号可以分别接入不同的控制电路。例如，U9芯片的输出接入LED显示模组中的恒流驱动芯片的SDI管脚，U10芯片的输出接入flash储存芯片的MOSI管脚以驱动校正电路，U11芯片的输出接入MCU驱动芯片的I/O口，上述处理后信号配合软件以及现场的其他信号分别触发不同的电路保证LED显示模组可以正常工作。
可选地，上述步骤可以包括如下过程：LED显示模组每次上电工作时，首先起作用的是U11芯片输出接入MCU的电路；当每次显示屏上电使用时MCU与接收卡电路会互相通讯握手匹配，在握手匹配过程中，除了该信号的时序，其余信号均置为低电平，其余电路全部不工作；握手成功则进行下一个电路的启动。LED显示模组中自 动载入配置文件后，开启U9芯片连接电路，正常点亮模组，此时U10和U11电路的其他信号均拉低芯片不起作用，该过程在时序上存在差异，不与其他电路干扰。当需要校正数据时，上位机软件发送校正指令，显示信号全部关闭，此时U10芯片链接的控制电路即校正电路被驱动并发挥功能。
需要说明的是，对于前述的各方法实施例，为了简单描述，故将其都表述为一系列的动作组合，但是本领域技术人员应该知悉，本申请并不受所描述的动作顺序的限制，因为依据本申请，某些步骤可以采用其他顺序或者同时进行。其次，本领域技术人员也应该知悉，说明书中所描述的实施例均属于优选实施例，所涉及的动作和模块并不一定是本申请所必须的。
通过以上的实施方式的描述，本领域的技术人员可以清楚地了解到根据上述实施例的信号传输方法可借助软件加必需的通用硬件平台的方式来实现，当然也可以通过硬件，但很多情况下前者是更佳的实施方式。基于这样的理解，本申请的技术方案本质上或者说对现有技术做出贡献的部分可以以软件产品的形式体现出来，该计算机软件产品存储在一个存储介质(如ROM/RAM、磁碟、光盘)中，包括若干指令用以使得一台终端设备(可以是手机，计算机，服务器，或者网络设备等)执行本申请各个实施例的方法。
根据本申请实施例，还提供了一种用于实施上述信号传输方法的信号传输装置，图6是根据本申请实施例提供的信号传输装置的结构框图，如图6所示，该信号传输装置包括：获取模块62和传输模块64，下面对该信号传输装置进行说明。
获取模块62，设置为获取与复用针脚一一对应的第一信号，其中，所述复用针脚位于电源信号共用输入接插件上，每个所述复用针脚用于连接LED灯板中的至少两个控制电路，每个所述第一信号分别用于驱动对应的复用针脚连接的所述至少两个控制电路中的第一子电路；

根据本申请实施例，还可以提供一种LED的显示模组。
如图8至图9所示，本实施例的LED显示模组包括LED灯板和电源信号共用输入接插件20。其中，LED灯板上设置有控制电路，控制电路包括多个复用针脚子电路和多个其他子电路；电源信号共用输入接插件20，设置在LED灯板的后侧，电源信号共用输入接插件包括多个复用针脚和多个其他针脚，其中，多个其他针脚与多个其他子电路一一对应地连接，每个复用针脚与至少两个复用针脚子电路连接。
应用本实施例的技术方案，将电源输入接口和信号输入接口集成在一起形成电源信号共用输入接插件20，这样电源盒40和每个LED显示模组之间只需要连接一根电源信号共用传输线30同时实现供电和信号的传输即可，使得电源盒40与每个LED显示模组之间的连接线的数量减少了一半，进而整个LED显示装置中的连接线的数量也减少了一半，这样简化了LED显示装置内部的线路连接，易于操作人员进行LED显示装置的组装。因此，本实施例的技术方案能够有效地解决相关技术中的组装LED显示装置时操作较为复杂的问题。
由于type-C线材即能够进行电能传输又能够进行信号传输，因此，在本实施例中，使用type-C线材作为电源信号共用传输线30以与电源信号共用输入接插件20连接。在现有技术中，LED模组上使用具有26个针脚的接口进行信号传输，使用具有4个针脚的接口进行电能传输，而type-C接口仅有24个针脚，因此在本实施例中，每个复用针脚与至少两个复用针脚子电路连接，将无需同时工作的不同的复用针脚子电路连接在同一个复用针脚上，实现连接针脚的复用，即使针脚的数量减少了，仍能够满足LED显示模组正常显示的需求。
需要说明的是，每个其他子电路仅与一个其他针脚连接，每个复用针脚子电路也仅与一个复用针脚连接。
本实施例中，复用针脚子电路可以包括上述信号传输方法实施例中的第一子电路和第二子电路。
具体地，如图3所示，在本实施例中，多个复用针脚包括第一针脚，多个复用针脚子电路包括第一显示电路和第一逻辑时序信号译码电路，第一显示电路和第一逻辑时序信号译码电路并联设置并与第一针脚连接。其中，第一显示电路传输列显示信号(DATA数据)，第一逻辑时序信号译码电路传输行显示信号，在LED显示装置正常 工作之前可以选择使第一显示电路工作还是使第一逻辑时序信号译码电路工作。具体地，第一针脚为图3中的11号针脚。
如图3所示，在本实施例中，多个复用针脚包括第二针脚，多个复用针脚子电路包括第二显示电路和第一校正电路，第二显示电路和第一校正电路并联设置并与第二针脚连接。其中，第二显示电路传输列显示信号(DATA数据)，第二显示电路和第一显示电路控制LED灯板上不同的显示区域。具体地，在LED显示装置的安装调试阶段，需要对每个LED显示模组的显示进行校正，在调试阶段，通过上位机或者控制软件手动触发，使得第一校正电路工作，此时第二显示电路传输低电平，即第二显电路控制的显示区域不发光；完成校正之后，使得第二显示电路工作，恢复其传输显示数据的功能。具体地，第二针脚为图3中的9号针脚。
如图3所示，在本实施例中，多个复用针脚包括第三针脚，多个复用针脚子电路包括第三显示电路和第二逻辑时序信号译码电路，第三显示电路和第二逻辑时序信号译码电路并联设置并与第三针脚连接。其中，第三显示电路传输列显示信号(DATA数据)，第二逻辑时序信号译码电路传输行显示信号。在LED显示装置正常工作之前可以选择使第三显示电路工作还是使第二逻辑时序信号译码电路工作。具体地，第三针脚为图3中的12号针脚。
如图3所示，在本实施例中，多个复用针脚包括第四针脚，多个复用针脚子电路还包括第四显示电路、第二校正电路和加密电路，第四显示电路、第二校正电路和加密电路并联设置并与第四针脚连接。其中，第四显示电路传输列显示信号(DATA数据)，加密电路工作时LED显示模组内的MCU(微控制单元)通过加密电路与LED显示装置内接收卡的MCU做通讯，只有通讯成功，LED显示模组才能正常显示，匹配成功之后加密电路停止工作，第四显示电路工作，恢复其传输显示数据(DATA)的功能；如果通讯不成功，则说明系统未匹配成功，则需要更换系统。需要说明的是，在本实施例中，第一校正电路和第二校正电路仅在LED显示设备调试阶段工作，且一般LED显示设备只需要进行一次调试即可，无需每一次显示之前均进行调试；而加密电路则是在每一次显示之前都会工作，LED显示装置上电之后，加密电路会先工作，只有通讯成功之后，LED显示装置才会正常显示画面。具体地，第四针脚为图3中的10号针脚。
在本实施例中，除了上述的四个针脚之外，电源信号共用输入接插件20内的多个其他针脚均只与一个子电路连接，且这些子电路均为本领域的常规电路。具体地，如图8所示，1号、2号、3号和4号针脚与电源电路VCC电路连接；21号、22号、23号和24号针脚与电源电路GND电路连接；5号、6号、7号和8号针脚与显示电路连接；13号、14号、15号针脚与逻辑时序信号译码电路连接；17号和18号针脚与校正 电路连接；16号、19号和20号针脚与逻辑时序信号电路连接。
如图8和图9所示，电源信号共用输入接插件20还包括壳体部21，每个其他针脚的一部分设置在壳体部21的内部，另一部分外露于壳体部21，每个复用针脚的一部分设置在壳体部21的内部，另一部分外露于壳体部21。其中，位于壳体部21内的其他针脚部分和复用针脚部分与电源信号共用传输线30连接，位于壳体部21外的其他针脚部分和复用针脚部分与各子电路连接。
如图8、图9和图11所示，壳体部21上设置有用于与电源信号共用传输线30的插头31插接配合的插口211。插头31和插口211之间插接配合，以实现电源盒40和LED显示模组之间的电能和信号传输。
如图8、图9和图11所示，插口211的内侧壁上设置有防呆凹部212，相应地，插头31上也设置有与防呆凹部212相配合的凸起结构。由于电源信号共用输入接插件20的每个针脚均需要连接相应的子电路，插头31插反之后会使得LED显示模组无法正常显示甚至可能烧坏LED显示模组，设置防呆凹部212能够有效地避免插头插反。
如图8、图9和图11所示，壳体部21上还设置有防脱凹部213，防脱凹部213与插口211间隔设置。由于电源信号共用传输线30具有一定的重量，LED显示设备组装好之后，电源信号共用传输线30会向受其自身重力作用向下拉拽插头31，在长期使用过程中插头31容易从插口211内脱出。在壳体部21上设置防脱凹部213，并对应在插头31上设置插入至防脱凹部213内的防脱凸起，使得插头31与插口211插接配合、防脱凸起与防脱凹部213插接配合，起到防拉脱效果。
如图10和图11所示，本申请还提供了一种LED显示装置，本申请的LED显示装置的实施例包括箱体、设置在箱体前侧的LED显示模组10、设置在箱体内或者设置在箱体后侧的电源盒40以及连接在LED显示模组10和电源盒40之间的电源信号共用传输线30，LED显示模组为上述的LED显示模组。上述的LED显示模组能够有效地解决相关技术中的组装LED显示装置时操作较为复杂的问题。具有上述LED显示模组的LED显示装置也具有上述的优点。
在本实施例中，电源盒40内既包括电源又包括控制板，电源与控制板集成之后通过一个电源信号共用输出接口与电源信号共用传输线30连接以为LED显示模组供电并传输控制信号。
