具体实施方式
为了便于理解本申请，下面将参照相关附图对本申请进行更全面的描述。附图中给出了本申请的较佳实施方式。但是，本申请可以以许多不同的形式来实现，并不限于本文所描述的实施方式。相反地，提供这些实施方式的目的是使对本申请的公开内容理解的更加透彻全面。
除非另有定义，本文所使用的所有的技术和科学术语与属于本申请的技术领域的技术人员通常理解的含义相同。本文中所使用的术语只是为了描述具体的实施方式的目的，不是旨在于限制本申请。
例如，提供一种显示屏动态控制系统，包括：接收卡及第一稳压供电模块；所述接收卡具有第一管脚，所述第一管脚与所述第一稳压供电模块的使能端连接，所述第一稳压供电模块的供电输出端用于与第一显示模组连接；所述接收卡用于在接收显示数据后，检测所述显示数据中是否存在用于驱动所述第一显示模组的发光信号；当所述显示数据不存在用于驱动所述第一显示模组的发光信号时，通过所述第一管脚向所述第一稳压供电模块的使能端发送第一控制信号，以使所述第一稳压供电模块停止工作。
上述的显示屏动态控制系统，通过接收卡在接收显示数据后，检测显示数据中是否存在第一显示模组的发光信号，即检测显示数据中第一显示模组需不需要发亮，当检测到第一显示模组不需要发亮时，接收卡的第一管脚输出第一控制信号，以使第一稳压供电模块断电，减少第一稳压供电模块及第一显示模块的待机损耗，从而减少电能的浪费，避免第一稳压供电模组在待机状态下导致箱体温度升高，且由于稳压供电模块的使能端响应速度快，即使显示屏在显示每一帧画面时，稳压供电模块的使能端接收的信号均不一样， 也不会影响显示屏正常显示。
在其中一个实施例中，请参阅图1，提供一种显示屏动态控制系统10，包括：接收卡100及第一稳压供电模块210；所述接收卡具有第一管脚，所述第一管脚与所述第一稳压供电模块210的使能端连接，所述第一稳压供电模块210的供电输出端用于与第一显示模组310连接；所述接收卡100用于在接收显示数据后，检测所述显示数据中是否存在用于驱动所述第一显示模组310的发光信号；当所述显示数据不存在用于驱动所述第一显示模组310的发光信号时，通过所述第一管脚向所述第一稳压供电模块210的使能端发送第一控制信号，以使所述第一稳压供电模块210停止工作。
值得一提的，所述显示屏为LED显示屏，所述接收卡即LED接收卡，也称为LED控制卡，接收卡具有中央处理器，相当于MCU(Microcontroller Unit，微控制单元)或者FPGA(Field-Programmable Gate Array，现场可编程门阵列)芯片，其具有对接收的显示数据进行分析处理的功能，具体的，显示屏的显示数据均会发送至接收卡中，接收卡用于接收显示数据，即接收卡接收显示屏需要显示的画面数据，并将显示数据经过处理后，发送至显示屏的驱动模块，即发送至第一显示模组，以使显示屏根据显示数据进行显示。
应当理解的，所述接收卡用于接收显示数据，即所述接收卡用于接收每一帧的显示数据，帧是影像动画中最小单位的单幅影像画面，即显示画面，相当于电影胶片上的每一格镜头。具体的，一帧就是一副静止的画面，连续的帧就形成动画，如电视图像等。我们通常说帧数，简单地说，就是在1秒钟时间里传输的图片的帧数，也可以理解为图形处理器每秒钟能够刷新几次，通常用fps(Frames Per Second,画面每秒传输帧数)表示。每一帧都是静止的图象，快速连续地显示帧便形成了运动的假象。高的帧率可以得到更流畅、更逼真的动画。每秒钟帧数(fps)越多，所显示的动作就会越流畅。对于LED显示屏，一般的，每秒30帧即每秒传输30帧数的显示数据，即可以使显示屏流畅画面。
可以理解的，所述接收卡用于在接收显示数据后，检测所述显示数据中 是否存在用于驱动所述第一显示模组的发光信号；当所述显示数据不存在用于驱动所述第一显示模组的发光信号时，通过所述第一管脚向所述第一稳压供电模块的使能端发送第一控制信号，即所述接收卡用于在接收到每一帧的显示数据后，均会对每一帧的显示数据进行检测，判断每一帧的显示数据中是否存在用于驱动所述第一显示模组的发光信号，当某一帧的显示数据中不存在用于驱动所述第一显示模组的发光信号时，在该帧的显示数据显示时间段，通过所述第一管脚向所述第一稳压供电模块的使能端发送第一控制信号，以使所述第一稳压供电模块停止工作，例如，所述接收卡在接收第一帧的显示数据后，检测所述第一帧的显示数据中是否存在用于驱动所述第一显示模组的发光信号，当所述第一帧显示数据不存在用于驱动所述第一显示模组的发光信号时，即第一帧的显示数据显示时，或者在接收卡接收到下一帧的显示数据前，通过所述第一管脚向所述第一稳压供电模块的使能端发送第一控制信号，以使所述第一稳压供电模块停止工作。
具体的，所述第一稳压供电模块的供电输出端与所述第一显示模组连接，即所述第一稳压供电模块用于给第一显示模组供电，以使第一显示模组工作。所述接收卡用于检测所述显示数据是否存在用于驱动所述第一显示模组的发光信号，即所述接收卡用于检测所述每一帧的显示数据是否存在用于驱动所述第一显示模组的发光信号，即检测所述第一显示模组中的灯珠是否需要发亮，当检测到某一帧的显示数据不需要所述第一显示模组中的灯珠发亮时，以控制第一稳压供电模块停止工作，即可以无需对第一显示模组供电，从而减少第一稳压供电模块及第一显示模组待机时的电能损耗。
所述接收卡通过所述第一管脚向所述第一稳压供电模块的使能端发送第一控制信号，以使所述第一稳压供电模块停止工作，具体的，使能端是指控制信号输入端，又叫使能输入端(enable)，它是芯片的一个输入引脚，或者电路的一个输入端口，只有该引脚激活，芯片才能工作，也就是说第一稳压供电模块的使能端激活时，第一稳压供电模块才工作，本实施例中，当第一稳压供电模块的使能端接收到第一控制信号时，第一稳压供电模块停止工作， 在一个实施例中，所述第一稳压供电模块为高电平有效时，所述第一控制信号为低电平信号；在一个实施例中，所述第一稳压供电模块为低电平有效时，所述第一控制信号为高电平信号。
具体的，所述第一稳压供电模块即DC(direct current，直流)供电模块，用于输出稳定的直流电，以为第一显示模组提供电能，在一个实施例中，所述第一稳压供电模块采用TLV62130型号的稳压供电芯片。稳压供电芯片的使能端响应速度在纳秒级，响应速度快，而一般的显示屏显示画面通常为一秒30帧，即每帧传输时间约为16.7毫秒，如此，即使显示屏在显示每一帧画面时，稳压供电模块的使能端接收的信号均不一样，也不会影响显示模组的正常供电，即不会影响显示屏正常显示，此外，接收卡对显示数据进行检测时，只需对显示数据中的发光信号进行检查，即只需要进行“0”和“1”的判断，其检测用时也是纳秒级，检测用时可以忽略不计，即不会造成显示屏显示异常，因此，本申请的显示屏动态控制系统不会影响显示屏的正常显示。
可以理解的，所述第一显示模组包括第一驱动模块及第一灯珠，所述第一驱动模块的输入端与所述第一稳压供电模块的供电输出端连接，所述第一驱动模块的输出端与所述第一灯珠连接，所述第一驱动模块用于驱动所述第一灯珠；例如，所述第一显示模组可以是指显示屏中一个箱体的所有灯珠及用于驱动灯珠的驱动模块，具体的，所述灯珠可以是显示屏中的一个箱体的一种颜色的灯珠，可以是显示屏中一个模组的灯珠，可以是显示屏中一个模组的一种颜色的灯珠，也可以是一个灯珠。具体的，用户可以根据实际需求进行设置。
上述的显示屏动态控制系统，通过接收卡在接收显示数据后，检测显示数据中是否存在第一显示模组的发光信号，即检测显示数据中第一显示模组需不需要发亮，当检测到第一显示模组不需要发亮时，接收卡的第一管脚输出第一控制信号，以使第一稳压供电模块断电，减少第一稳压供电模块及第一显示模块的待机损耗，即降低显示屏的电能损耗，从而减少电能的浪费， 避免第一稳压供电模组在待机状态下导致箱体温度升高，且由于稳压供电模块的使能端响应速度快，即使显示屏在显示每一帧画面时，稳压供电模块的使能端接收的信号均不一样，也不会影响显示屏正常显示。
为了使显示屏能够正常显示，在其中一个实施例中，当所述接收卡检测到所述显示数据存在用于驱动所述第一显示模组的发光信号时，通过所述第一管脚向所述第一稳压供电模块的使能端发送第二控制信号，以使所述第一稳压供电模块工作。具体的，所述接收卡需要对每一帧的显示数据进行检测，并判断每一帧的显示数据是否存在用于驱动所述第一显示模组的发光信号，即检测所述显示数据是否需要第一显示模组发亮，当检测到存在用于驱动所述第一显示模组的发光信号时，即说明这一帧的显示画面需要第一显示模组工作，接收卡通过第二管脚向所述第一稳压供电模块的使能端发送第二控制信号，以使所述第一稳压供电模块给所述第一显示模组供电，使得显示屏正常显示，值得一提的，所述第一控制信号及第二控制信号是两个相反信号，即当第一控制信号为低电平信号时，所述第二控制信号为高电平信号；当第一控制信号为高电平信号时，所述第二控制信号为低电平信号；在一个实施例中，所述第一稳压供电模块为高电平有效时，所述第一控制信号为高电平信号；在一个实施例中，所述第一稳压供电模块为低电平有效时，所述第一控制信号为低电平信号。在其中一个实施例中，所述第一控制信号为低电平信号，所述第二控制信号为高电平信号。
在其中一个实施例中，请参阅图2，所述第一稳压供电模块210包括第一稳压供电芯片U1及周围电路，具体的，第一稳压供电芯片U1的电源端用于与电源连接，第一稳压供电芯片的使能端与所述接收卡的第一管脚连接，第一稳压供电芯片的供电输出端与所述第一显示模组连接，具体的，第一稳压供电芯片的使能端即第一稳压供电芯片的EN管脚，第一稳压供电芯片根据接收卡发出的控制信号，以使第一稳压供电芯片是否工作,从而减少显示屏待机时，第一稳压供电芯片的电能损耗。
在其中一个实施例中，请参阅图3，所述的显示屏动态控制系统10还包括发送卡400及第二稳压供电模块220，所述接收卡具有第二管脚，所述第二管脚与所述第二稳压供电模块220的使能端连接，所述第二稳压供电模块的供电输出端用于与第二显示模组320连接；所述发送卡用于向所述接收卡发送显示数据前，检测所述显示数据中是否存在用于驱动所述第二显示模组的发光信号，当所述显示数据不存在用于驱动所述第二显示模组的发光信号时，向所述接收卡发送第一触发信号；所述接收卡用于在接收到所述第一触发信号时，通过所述第二管脚向所述第二稳压供电模块的使能端发送所述第一控制信号，以使所述第二稳压供电模块停止工作。
值得一提的，发送卡具有中央处理器，相当于MCU(Microcontroller Unit，微控制单元)或者FPGA(Field-Programmable Gate Array，现场可编程门阵列)芯片，其具有对显示数据进行分析处理的功能，从而可以对显示数据进行检测。
值得一提的，发送卡用于向所述接收卡发送显示数据，例如，接收卡接收的是当前显示画面的显示数据，此时发送卡向所述接收卡发送下一帧的显示画面的显示数据，以使接收卡能够连续接收显示数据。具体的，一个接收卡要接收显示屏中一个箱体或者多个显示模组的显示数据，如果将这些数据均通过接收卡进行检查判断，则接收卡需要承担较大的压力，例如，一个大屏显示系统，接收卡需要接收较多灯珠的发光信号，即接收卡需要相对较长的时间进行检测，从而有可能影响显示屏的正常显示，通过设置发送卡，发送卡用于在向所述接收卡发送所述显示数据前，先对所述显示数据进行检测，检测所述显示数据是否存在用于驱动所述第二显示模组的发光信号，当发送卡检测到所述显示数据不存在用于驱动所述第二显示模组的发光信号时，生成所述第一触发信号，所述第一触发信号随着所述显示数据一起发送至接收卡，所述接收卡用于在接收所述显示数据时，检测是否接收到所述第一触发信号，当接收卡接收到第一触发信号时，通过所述第二管脚向所述第二稳压供电模块的使能端发送将所述第一控制信号，以使所述第二稳压供电模块停 止工作；如此，通过设置发送卡配合接收卡对显示数据进行检测，减小了接收卡的负担，从而可以提高检测效率，以更好的使显示屏正常显示。应当理解的，所述发送卡与所述接收卡的检测原理相同，本实施例中，不再赘述。
在一个实施例中，所述显示数据包括第一显示数据及第二显示数据，第一显示数据用于驱动第一显示模组，第二显示数据用于驱动第二显示模组，发送卡用于检测第二显示数据，接收卡用于检测第一显示数据，且第一显示数据不存在用于驱动所述第二显示模块对应的发光信号，所述第二显示数据不存在用于驱动所述第一显示模块对应的发光信号，即使发送卡检测一部分显示数据，接收卡检测另一部分显示数据，从而避免接收卡及发送卡对同一显示数据进行检测，从而进一步提升检测效率。
在其中一个实施例中，当所述接收卡没有接收到所述第一触发信号时，通过所述第二管脚向所述第二稳压供电模块的使能端发送第二控制信号，以使所述第二稳压供电模块工作，具体的，所述发送卡需要对每一帧的显示数据进行检测，并判断每一帧的显示数据是否存在用于驱动所述第二显示模组的发光信号，即检测所述显示数据是否需要第二显示模组发亮，当检测到存在用于驱动所述第二显示模组的发光信号时，即说明这一帧的显示画面需要第二显示模组工作，如此，当接收卡接收这一帧的显示数据时，没有接收到第一触发信号，接收卡通过第二管脚向所述第一稳压供电模块的使能端发送第二控制信号，以使所述第二稳压供电模块给所述第一显示模组供电，使得显示屏正常显示。
在其中一个实施例中，当所述发送卡检测到所述显示数据存在用于驱动所述第二显示模组的发光信号时，向所述接收卡发送第三触发信号，所述接收卡用于接收到所述第三触发信号时，通过所述第二管脚向所述第二稳压供电模块的使能端发送所述第二控制信号，以使所述第二稳压供电模块工作。在一个实施例中，所述第一触发信号即第一控制信号，第三触发信号即第二控制信号，具体的，接收卡是通过网线与发送卡对应连接，所述发送卡向所述接收卡发送所述显示数据时，根据检测结果将对应的第一控制信号或者第 二控制信号发送至接收卡的第二管脚上，以使对应的控制信号通过接收卡的第二管脚发送至第二稳压供电模块，以使第二稳压供电模块工作或停止工作，如此，只需要进行简单的信号传输即可，从而进一步提升接收卡的检测效率。
为了进一步降低显示屏的待机损耗，在其中一个实施例中，请参阅图4，所述显示屏动态控制系统10还包括第二稳压供电模块220、第三稳压供电模块230及发送卡400，所述发送卡400与所述接收卡100连接，所述接收卡具有第三管脚，所述第三管脚与所述第三稳压供电模块230的使能端连接，所述第三稳压供电模块230的供电输出端分别与所述第一稳压供电模块210的电源端及所述第二稳压供电模块220的电源端连接，所述第二稳压供电模块220的供电输出端用于与第二显示模组320连接；所述发送卡400用于向所述接收卡100发送所述显示数据前，检测所述显示数据中是否存在用于驱动所述第二显示模组320的发光信号，当所述显示数据不存在用于驱动所述第二显示模组320的发光信号时，向所述接收卡100发送第一触发信号；所述接收卡100用于接收到所述第一触发信号以及检测到不存在用于驱动所述第一显示模组310的发光信号时，通过所述第三管脚向所述第三稳压供电模块230的使能端发送第三控制信号，以使所述第三稳压供电模块230停止工作。具体的，第三稳压供电模块230的供电输出端分别与所述第一稳压供电模块210的电源端及所述第二稳压供电模块220的电源端连接，即第三稳压供电模块230用于给第一稳压供电模块210及第二稳压供电模块220提供电源。
可以理解的，显示屏具有多个显示模组，每一显示模组与一稳压供电模块对应连接，则通常会设置一个稳压供电模块用于给支路的稳压供电模块供电，因此，当检测到所述显示数据不存在第一显示模组及第二显示模组的发光信号时，通过接收卡的第三管脚向所述第三稳压供电模块的使能端发送第三控制信号，以使所述第三稳压供电模块停止工作，即检测到第一显示模组及第二显示模组不需要发亮时，使第三稳压供电模块停止工作，从而进一步降低显示屏的电能损耗。
在其中一个实施例中，当所述接收卡未接收到所述第一触发信号或存在用于驱动所述第一显示模组的发光信号时，通过所述第三管脚向所述第三稳压供电模块的使能端发送所述第四控制信号，以使所述第三稳压供电模块工作。
值得一提的，所述第三控制信号及第四控制信号是两个相反信号，即当第三控制信号为低电平信号时，所述第四控制信号为高电平信号；当第三控制信号为高电平信号时，所述第四控制信号为低电平信号；在一个实施例中，所述第三稳压供电模块为高电平有效时，所述第三控制信号为高电平信号；在一个实施例中，所述第三稳压供电模块为低电平有效时，所述第三控制信号为低电平信号。在其中一个实施例中，所述第三控制信号为低电平信号，所述第四控制信号为高电平信号。
为了进一降低显示屏待机时的电能损耗，在其中一个实施例中，所述接收卡还用于在检测到所述显示数据中不存在发光信号时，停止发送所述显示数据。具体的，所述显示数据除了包括发光信号外，即R，G，B信号，还包括发光控制信号，例如：时钟信号CLK、锁存信号LAT及行选择信号A，B，C等。即显示屏在不显示的时候，发光控制信号的传输仍会造成电能的损失，如此，当接收卡检测到所述显示数据不存在发光信号时，通过让接收卡停止发送所述显示数据，以进一步降低显示屏的电能损耗。
为了便于用户对显示模组进行维护，在其中一个实施例中，所述接收卡还用于在接收到第二触发信号时，通过所述第一管脚向所述第一稳压供电模块的使能端发送第一控制信号，以使所述第一稳压供电模块停止工作。具体的，所述第二触发信号可以通过外接设备进行发送，例如：键盘，按键等，当用户需要对第一显示模组进行维护时，通过外接设备发送第二触发信号，当所述接收卡接收到所述第二触发信号时，所述第一管脚输出第一控制信号，以使第一稳压供电模块停止工作，即使第一稳压供电模块停止对第一显示模组供电，无需对整个显示系统断电，可以有效防止带电插拔带来的安全隐患，从而便于对显示模组的维护。
在一个实施例中，所述第一显示模组为显示屏的一箱体的显示电路，包括该箱体的所有灯珠及驱动电路，即所述第一稳压供电模块用于给显示屏的一箱体的显示电路供电，所述接收卡用于检测所述显示数据是否存在用于驱动所述第一显示模组的发光信号，即检测该箱体是否需要发亮，当箱体不需要发亮时，接收卡通过所述第一管脚向所述第一稳压供电模块发送第一控制信号，以使第一稳压供电模块停止工作，即使得所述第一稳压供电模块停止给所述第一显示模组供电。此显示屏动态控制系统适用于显示大屏系统，尤其是显示大屏系统中边角的箱体。
在一个实施例中，所述第一显示模组为显示屏的一显示模组，所述接收卡用于检测所述显示数据是否存在用于驱动所述第一显示模组的发光信号，即检测该显示模组是否需要发亮，当所述显示模组不需要发亮时，接收卡通过所述第一管脚向所述第一稳压供电模块发送第一控制信号，以使第一稳压供电模块停止工作，即使得所述第一稳压供电模块停止给所述第一显示模组供电。需说明的，一个显示屏通常由多个显示箱体拼接而成，而一个显示箱体又由多个模组组成，接收卡只需要检查所述显示数据中是否存在对应显示模组的发光信号，以控制对应的稳压供电模块停止工作。
在另一个实施例中，所述第一显示模组包括至少第一灯珠及驱动模块，所述第一稳压供电模块的供电输出端与所述第一驱动模块的供电输入端连接，各所述第一灯珠与所述第一驱动模块的输出端连接，各所述第一灯珠的发光颜色相同，例如：第一灯珠为显示屏的红色灯珠；例如，第一灯珠为显示屏的蓝色灯珠，又例如，第一灯珠为显示屏的绿色灯珠，通过采用对显示屏的不同颜色的灯珠进行分路供电，当显示屏不需要某一颜色的灯珠发亮时，控制对应的稳压供电模块停止工作，以进一步降低显示屏的电能损耗。
在其中一个实施例中，所述显示屏动态控制系统包括至少一个第一稳压供电模块，所述接收卡具有至少一个第一管脚，每一所述第一稳压供电模块的使能端与一所述第一管脚一一对应连接，每一所述第一稳压供电模块的供电输出端用于与一第一显示模组连接，所述接收卡用于检测所述显示数据是 否存在第一显示模组的发光信号，当所述显示数据不存在用于驱动所述第一显示模组的发光信号时，通过对应的第一管脚向所述第一稳压供电模块的使能端发送第一控制信号，以使所述第一稳压供电模块停止工作。
在其中一个实施例中，所述显示屏动态控制系统包括至少一个第二稳压供电模块，所述接收卡具有至少一个第二管脚，每一所述二稳压供电模块的使能端与一所述第二管脚一一对应连接，每一所述第二稳压供电模块的供电输出端与一第二显示模组连接，所述发送卡用于向所述接收卡发送显示数据前，检测所述显示数据中是否存在用于驱动所述第二显示模组的发光信号，当所述显示数据不存在用于驱动所述第二显示模组的发光信号时，向所述接收卡发送第一触发信号；所述接收卡用于在接收到所述第一触发信号时，通过所述第二管脚向所述第二稳压供电模块的使能端发送所述第一控制信号，以使所述第二稳压供电模块停止工作。
在其中一个实施例中，请参阅图5，提供一种显示屏20，包括第一显示模组310及上述任一实施例中所述的显示屏动态控制系统，所述第一稳压供电模块的供电输出端210与所述第一显示模组连接。
上述的显示屏，通过接收卡在接收显示数据后，检测显示数据中是否存在第一显示模组的发光信号，即检测显示数据中第一显示模组需不需要发亮，当检测到第一显示模组不需要发亮时，接收卡的第一管脚输出第一控制信号，以使第一稳压供电模块断电，减少第一稳压供电模块及第一显示模组的待机损耗，从而减少电能的浪费，避免第一稳压供电模组在待机状态下导致箱体温度升高，且由于稳压供电模块的使能端响应速度快，即使显示屏在显示每一帧画面时，稳压供电模块的使能端接收的信号均不一样，也不会影响显示屏正常显示。
为了进一步降低显示屏待机时的电能损耗，在其中一个实施例中，请参阅图6，所述第一显示模组310包括第一灯珠311及第一驱动模块312，所述第一稳压供电模块210的供电输出端与所述第一驱动模块312的供电输入端连接，所述第一驱动模块312的输出端与所述第一灯珠311连接。具体的， 所述第一驱动模块312用于根据显示数据驱动所述第一灯珠311，第一稳压供电模块210用于第一驱动模块312供电，如此，第一显示模组310相当于显示箱体的一个模组，即接收卡100检测到显示数据不存在驱动第一灯珠311的发光信号时，通过所述第一管脚向所述第一稳压供电模块310的使能端发送第一控制信号，以使第一稳压供电模块310停止工作，降低第一稳压供电模块210的待机损耗同时，并使第一驱动模块312断电，降低第一驱动模块312的待机损耗，从而进一步降低了显示屏20待机时的电能损耗。
在其中一个实施例中，所述第一显示模组包括至少一个第一灯珠及第一驱动模块，各所述第一灯珠的发光颜色相同，所述第一稳压供电模块的供电输出端与所述第一驱动模块连接，所述第一驱动模块的输出端分别与各所述第一灯珠连接。具体的，第一灯珠为红色灯珠、蓝色灯珠及绿色灯珠的一种，所述第一驱动模块用于驱动各所述第一灯珠，即所述第一驱动模块只用于驱动一种颜色的灯珠，也就是说对于不同颜色的灯珠采用不同的驱动模块，可以理解的，对显示屏的不同颜色的灯珠采用分路供电，即每一颜色的灯珠采用一驱动模块驱动，则当显示屏中某一颜色的灯珠不需要发光时，接收卡发出第一控制信号，控制对应的稳压供电模块停止工作，降低稳压供电模块及驱动模块的待机功耗，，以最大化的降低显示屏的待机电能损耗，例如，应用于交通诱导屏，一般的交通诱导屏只需要红色灯珠或者绿色灯珠中的一种发亮，又例如，用于显示红底证件照，底色部分绿色灯珠及蓝色灯珠不需要发亮；例如，显示屏包括三个第一显示模组，分别对应红色灯珠、蓝色灯珠及绿色灯珠，第一稳压供电模块的数量有三个，每一第一稳压供电模块的供电输出端与一第一显示模组对应，接收卡具有三个第一管脚，每一第一管脚与与稳压供电模块的使能端连接，当接收卡检测到无需某一颜色的灯珠发亮时，通过对应的第一管脚向对应的第一稳压供电模块发出第一控制信号，以使第一稳压供电模块停止工作，降低第一稳压供电模块的待机损耗，即降低显示屏的电能损耗。
以上所述实施例的各技术特征可以进行任意的组合，为使描述简洁，未 对上述实施例中的各个技术特征所有可能的组合都进行描述，然而，只要这些技术特征的组合不存在矛盾，都应当认为是本说明书记载的范围。
