Because the LED display screen can be widely applied to various scenes such as traffic signal lamps, literature shows, news releases and the like, the display requirements of people on the LED display screen are higher and higher. In the display requirements of the LED display screen, the display area, the display duration and the display power consumption are three important display indexes which are concerned by people. The larger the display area of the LED display screen is, the longer the display time is, and the larger the power consumption of the LED display screen is. Therefore, on the premise of meeting the requirements on the display area and the display duration of the LED display screen, how to save the power consumption of the LED display screen becomes a great problem in the technical field.
At present, people usually adopt a method of upper computer software regulation and control to solve the problem of high power consumption of the LED display screen, and the upper computer software regulation and control can carry out balance control on three-phase alternating current power supply of a power distribution cabinet according to the actual load requirement of an electric appliance so as to achieve the purpose of reducing the power consumption of the LED display screen.

In order to describe the scheme of the present application more clearly, some knowledge related to the LED display screen is introduced below.
LED display screen box: the LED display screen box is simply a screen body composed of a plurality of display units (unit display panels or unit display boxes) which can be combined and spliced. In order to meet different environments, a set of appropriate controllers (a main control board or a control system) is added, so that display boards (or unit boxes) with various specifications can be matched with controllers with different control technologies to form a plurality of LED display screens, and different display requirements are met. The area of the LED display screen box body cannot be too large, and generally, one box body and one display screen are arranged; the installation is mainly carried out by adopting a hoisting mode; the display screens on the two sides can share one LED control card, the control card adopts a partition control card, the areas of the two sides are generally equal, the display contents are also the same, and only the software contents need to be divided into two parts which are the same. The LED display screen box body is applied to various fields of stages, meetings and the outdoors, because the weight of the template is heavy, the use is inconvenient, the cost is also high, and the LED display screen box body is transformed along with the promotion of the technology, so that the LED display screen box body is more and more simplified. The LED display screen box body has fast heat dissipation and high heat dissipation performance, and can effectively protect the module circuit; the anti-interference and special anti-electromagnetic wave interference function is realized; the strength is high, and the tensile test of the box body reaches 300 Kg.
LED display screen module: the LED display screen module is one of main components forming a finished LED display screen, and mainly comprises an LED lamp, a PCB (printed Circuit Board), a driving IC (integrated Circuit), a resistor, a capacitor and a plastic sleeve.
The LED display screen module can be divided into the following parts according to colors: monochrome modules, such as single red, single green, single blue, single yellow, single white modules; bi-color modules, such as red-green bi-color, red-blue bi-color; a full-color module mainly uses a product with red, green and blue three primary colors on one LED module. The LED display screen module can be divided into an indoor module, a semi-outdoor module and an outdoor module according to different use spaces. According to the difference of using LED encapsulation device, LED display screen module still can divide into: a direct plug-in light LED display screen module, a Surface Mounted Device (SMD) LED display screen module, and a cob (chip on board) packaged display screen module.
The embodiments of the present application will be described below with reference to the drawings.
Referring to fig. 1, fig. 1 is a schematic diagram illustrating a conventional LED display screen application. As shown in fig. 1, the architecture diagram includes an LED display device, a transmitter card device, an LED screen control computer, a power supply, and a switch. The power supply is used for supplying power to the sending card device and the LED display device, and a user can control the on and off of the power supply through the switch, so that the sending card device and the LED display device are controlled to be started. The LED screen control computer outputs a video signal to the LED display device, and the video signal is used for presenting corresponding image information through the LED display screen in the LED display device. The LED screen control computer is connected with the sending card equipment through a network, and data transmission can be carried out between the LED screen control computer and the sending card equipment through a High Definition Multimedia Interface (HDMI) or a Digital Visual Interface (DVI). After the sending card equipment obtains the power supply of the power supply to start, the video signal of the LED screen control computer can be forwarded to the receiving card, and the video signal forwarded by the sending card equipment is a parallel video signal. The LED display device can start a driving module in the LED display device after obtaining power supply of a power supply, and then starts an LED display screen in the LED display device, the driving module in the LED display device converts a parallel video signal sent by a sending card device into a serial video signal which can be identified by the LED display screen after receiving the parallel video signal, and transmits the serial video signal to the LED display screen, and the LED display screen lights an LED lamp bead and displays image information corresponding to the serial video signal after receiving the serial video signal.
In the framework of the LED display screen application, a user turns on a power supply through a power switch to supply power to the sending card device and the LED display device, all the devices enter a self-starting state, and after the starting is completed, the LED display device enters a normal display state. Secondly, in the using process of a user, a certain time is needed for starting the LED display screen, if the time interval between two uses is short, the LED display device adopts a standby mode, the conventional standby mode means that the LED display screen is in black screen display, the background of the LED display screen is still in normal operation although the LED display screen is not lightened, and the power loss of the part is large.
Aiming at the problem that the power consumption is large in the framework of the LED display screen application, the embodiment of the application provides a novel framework of the LED display screen application, and the framework can effectively solve the problem that the power consumption of LED display equipment is large in a starting mode and a standby mode.
Referring to fig. 2, fig. 2 is a schematic diagram of an architecture of an LED display screen application according to an embodiment of the present disclosure. As shown in fig. 2, the architecture diagram includes an LED display device, a transmitting card device, an LED screen control computer, a power management module, and a switch corresponding thereto, wherein the transmitting card device and the LED display device each include a power supply 1 and a power supply 2 for supplying power to themselves, respectively. The user can control the control signal transmission of the power supply management module through the switch, and the control signal can be used for controlling the on and off of the power supply 1 and the power supply 2, so that the effect of indirectly controlling the start of the transmitting card device and the LED display device is achieved. Specifically, the control signal sent by the power management module may also be used to control the turn-on timing of the power supply 1 and the power supply 2, that is, the sending card device and the LED display device may be controlled to be started in different timings. Therefore, the power management module can firstly turn on the power supply 1 by sending the control signal to enable the card sending device to be started preferentially, and then turn on the power supply 2 by sending the control signal to enable the LED display device to be started after the card sending device is started, so that power consumption waste caused by waiting for the card sending device to be started is avoided, and the problem that the power consumption of the LED display device is large in the starting mode can be effectively solved. And when the LED display equipment is in the standby mode, the power management module in the LED display equipment can control the LED display screen in the LED display equipment to be powered off by controlling the power supply 2 to be switched off, so that the problem of high power consumption of the LED display equipment in the standby mode can be effectively solved. In addition, the connection relationship and signal transmission of the LED screen control computer, the card sending device, and the LED display device in this architecture are similar to those in fig. 1, and therefore are not described herein again.
Based on the architecture of the LED display screen application provided in fig. 2, an embodiment of the present application further provides an energy saving method for an LED display screen, please refer to fig. 3, and fig. 3 is a schematic flow diagram of the energy saving method for an LED display screen provided in the embodiment of the present application, where the method includes, but is not limited to, the following steps:
step 301: and the terminal equipment receives the starting instruction.
The terminal device in this embodiment is the same device as the power management module in the architecture of fig. 2, and may be a computer with a data transmission function, or an integrated circuit or a module, which may be understood as an electronic device capable of performing data transmission with the card sending device and the LED display device.
The terminal device receives a starting instruction, the starting instruction can be sent by a user in an instruction control mode, the sending mode of the instruction control can be a key, touch control and the like, and the starting instruction can also be sent by other mobile device software control, and the starting instruction is used for indicating the terminal device to start the LED display device.
Step 302: the terminal equipment sends a first control signal to the card sending equipment for starting the card sending equipment.
After receiving the starting instruction, the terminal device does not immediately send a control signal to the LED display device to start the LED display device.
