根据图2所示的示例，在一个可能的示例场景中，当蓝牙模块12在接收到预先设定的蓝牙匹配信号时，通过蓝牙模块12与外部终端设备的匹配成功，蓝牙模块12的使能单元21会输出高电平使能信号。控制模块13通过输入的使能信号达到开启工作模式，进而控制显示模块的开启，同时在LED灯驱动单元22的驱动下，显示模块输出预先设定的显示结果，实现对显示装置的开启操作。当蓝牙模块12与外部终端设备匹配失败时，使 能单元21输出低电平使能信号。控制模块通过输入的低电平使能信号开启关闭模式，并控制显示模块处于关闭状态，显示模块不输出显示结果。此时显示装置处于关闭状态，从而实现了降低功耗，提高显示装置安全性的效果。According to the example shown in Fig. 2, in a possible example scenario, when the bluetooth module 12 receives the preset bluetooth matching signal, the matching of the bluetooth module 12 and the external terminal device is successful, and the enabling of the bluetooth module 12 Unit 21 will output a high-level enable signal.

在一种可能的示例中，当蓝牙模块12接收到外部匹配信号，并与外部终端设备匹配成功时，通过蓝牙模块12输出高电平信号。通过控制模块13的第一电阻R1和第二电阻R2的分压保护作用后输出高电平信号，此时的高电平信号达到了可控元件U1的导通电压，可控元件U1开启，控制模块13开启工作模式。可控元件U1开启后将电源电压(以下称为VCC)稳定输出，提供给显示模块14稳定的输入电压。显示模块14在电源电压VCC的供电下，显示模块14开启显示状态。同时在蓝牙模块12的控制下，显示模块14得到预先设定的显示结果，实现对显示装置的开启操作。当蓝牙模块12与外部终端设备匹配失败时，输出低电平信号。通过第一电阻R1和第二电阻R2的分压保护作用后，仍然输出低电平信号，低电平信号未达到可控元件U1的导通电压，使得可控元件U1无法导通，控制模块 13处于关闭模式。可控元件U1无法导通，阻断电源电压VCC的输出，使得显示模块14处于关闭状态，显示模块14不输出显示结果。完成了对显示装置的关闭操纵。从而实现了降低功耗，提高显示装置安全性的效果。In a possible example, when the Bluetooth module 12 receives an external matching signal and successfully matches with the external terminal device, the Bluetooth module 12 outputs a high-level signal. After the voltage division protection function of the first resistor R1 and the second resistor R2 of the control module 13, a high-level signal is output.

At the same time, under the control of the bluetooth module 12, the display module 14 obtains a preset display result to realize the opening operation of the display device. When the Bluetooth module 12 fails to match with the external terminal device, it outputs a low-level signal. After the voltage division protection function of the first resistor R1 and the second resistor R2, the low-level signal is still output, and the low-level signal does not reach the conduction voltage of the controllable element U1, so that the controllable element U1 cannot be turned on, and the control module 13 is in off mode. The controllable element U1 cannot be turned on, and the output of the power supply voltage VCC is blocked, so that the display module 14 is in a closed state, and the display module 14 does not output a display result. The closing manipulation of the display unit is completed. Therefore, the effects of reducing power consumption and improving the safety of the display device are achieved.

在一种可能的示例中，当蓝牙模块12与外部终端设备匹配成功时，输出高电平信号，控制模块13通过输入的高电平信号开启工作模式，将电源电压VCC稳定输出给滤波单元23。通过滤波作用后将输出的电源信号给LED灯阵列24，开启LED灯阵列24显示状态。在蓝牙模块12的控制下，LED灯阵列24显示出预先设定的显示结果，完成显示装置的开启操作。当蓝牙模块12与外部移动终端设备匹配失败后，输出低电平信号。控制模块13在输入的低电平信号后处于关闭模式，阻断电源电压VCC输出，滤波单元23接收不到电源信号，使得LED灯阵列24处于关闭状态，LED灯阵列24不输出显示结果。从而完成对显示装置的关闭操作，从而实现了降低功耗，提高显示装置安全性的效果。In a possible example, when the Bluetooth module 12 is successfully matched with the external terminal device, it outputs a high-level signal, and the control module 13 starts the working mode through the input high-level signal, and stably outputs the power supply voltage VCC to the filter unit 23 . After filtering, the output power signal is sent to the LED lamp array 24, and the LED lamp array 24 is turned on to display the status. Under the control of the Bluetooth module 12, the LED light array 24 displays a preset display result, and completes the opening operation of the display device. When the Bluetooth module 12 fails to match with the external mobile terminal device, it outputs a low-level signal. The control module 13 is in the off mode after the low level signal is input, and the output of the power supply voltage VCC is blocked, and the filter unit 23 cannot receive the power signal, so that the LED light array 24 is in the off state, and the LED light array 24 does not output display results. Thus, the closing operation of the display device is completed, thereby realizing the effect of reducing power consumption and improving the safety of the display device.

At the same time, under the driving action of the LED lamp driving unit, the LED lamp array is made to output a preset display result, and the opening operation of the display device is completed. When the Bluetooth module fails to match with the external mobile terminal device, the enabling unit outputs a low-level signal, and the input low-level signal does not reach the conduction voltage of the controllable element, and the controllable element is not turned on. The controllable element is disconnected, blocking the power signal output of the power module, and the filter unit cannot obtain the power signal, so that the LED light array is in the off state, and the LED light array does not output display results, and the display device is turned off. Therefore, the effects of reducing power consumption and improving the safety of the display device are realized.

The π-type filter circuit formed by the inductance element L1, the first capacitor C1 and the second capacitor C2 can obtain a more stable output voltage, and turn on the display state of the LED lamp array 24 . Under the action of the LED lamp driving unit 22, the LED lamp array 24 outputs a preset display result, so as to realize the opening operation of the display device. When the Bluetooth module 12 fails to match with the external mobile terminal device, it outputs a low-level signal. The control module 13 turns on the shutdown mode through the low-level signal, and controls the power supply module 11 to output a power signal. The inductive element L1 cannot receive the power signal and cannot pass The first capacitor C1 and the second capacitor C2 output the working voltage of the LED lamp array 24, so that the display result of the LED lamp array 24 cannot be output, and then the shutdown operation of the display device is completed. The external mobile terminal equipment cannot scan the display results, and thus cannot realize the opening operation of the display device, thereby achieving the effect of reducing power consumption and improving the safety of the display device.

Through the parallel connection of the LED lamp sub-units 31 in the circuit, the display operation on the LED lamp sub-units 31 is started. Under the driving action of the LED light driving unit 22 of the Bluetooth module 12, the LED light sub-unit 31 is controlled to output a preset display result, and the display operation of the display device is completed. When the Bluetooth module 12 fails to match with the external mobile terminal device, the control module 13 turns on the shutdown mode to block the power signal output of the power module 11 . The filter unit 23 cannot output the power signal without the power signal, so that the LED lamp sub-unit 31 does not output the display result, and then completes the shutdown operation of the display device. The display result cannot be scanned by the external mobile terminal equipment, and the operation of turning on the display device fails, thereby achieving the effects of reducing power consumption and improving the security of the display device.

After filtering by the filtering unit 23, a stable power signal is output. Under the current limiting effect of the third resistor R3, the diode element D1 conducts forwardly to realize the display function. Under the driving action of the LED light driving unit 22 of the Bluetooth module 12, the diode element D1 displays a preset display image. The external mobile terminal device completes the opening operation of the display device by scanning the displayed image. When the Bluetooth module 12 fails to match with the external mobile terminal device, the control module 13 turns on the shutdown mode, and blocks the power module 11 from outputting a power signal to the display module. The filtering unit 23 in the display module 14 cannot perform power filtering and cannot output a power signal, so that the diode element D1 cannot be turned on, and the display result is in an off state. The external mobile terminal device cannot scan to display the result, and the display device fails to be turned on. Therefore, the effects of reducing power consumption and improving the safety of the display device are achieved.

Further, the power supply module is controlled to output the power signal to the inductance element, and a stable power signal is obtained through the filtering effect of the inductance element, the first capacitor and the second capacitor.

Under the driving action of the LED lamp driving unit, the pre-set LED lamp displays an image, and outputs the display image. The external mobile terminal device completes the opening operation of the display device by scanning the displayed image. When the Bluetooth module fails to match with the external mobile terminal, the enabling unit outputs a low-level signal, which fails to reach the conduction voltage of the controllable element, and the controllable element is not turned on. In turn, the power supply module is blocked from outputting a power supply signal.
