In the present invention, since the base LED module control unit provided in each stage in the multi-stage LED display board communicates with the user by inputting a function key provided in the remote controller, the base LED module is individually controlled and integrated control by each stage by the transmitted LED control signal. Therefore, the present invention relates to a multi-stage remote control type LED display system that can display the contents displayed on the screen for each stage or over the front end.

Light Emitting Diode (LED) is a light emitting diode that emits light and has many kinds of colors and sizes such as red, green, blue, and white, but mainly uses RED and GREEN, and has a semi-permanent life of about 50,000 hours and low power consumption. It is a cutting-edge device that will greatly contribute to the future advertising industry.

By arranging a plurality of LEDs in a tiled manner, only a part of the LEDs are turned on to implement an electric signboard. At present, these LED signboards are panelized and each pixel panel is horizontally and vertically. It consists of arranged pixels.

By connecting the pixel panels in the horizontal direction as many as desired, one stage LED display board can be realized. That is, the LED display board is composed of a combination of one or more square pixel panels, each pixel panel is a combination of pixels arranged in a × a, each pixel is of a different color constituting the pixel The LED is combined.

For example, the pixel panel is a square, consisting of 16 * 16 vertically, that is, 256 LED DOT, a letter composed of Hangul vowels, consonants is represented, and the LED panel is manufactured by connecting several modules. The size of the module varies from 64mm to 1000mm depending on the purpose, but one module is composed of 256 DOTs regardless of size, and one Korean character is represented. That is, 8 characters of Korean characters are expressed at one time in the eight vertical display panels, and 16 characters of eight characters at the top and eight characters at the bottom of the eight display panels are displayed.

In addition, the conventional LED sign is divided into a remote control type and a PC (personal computer) connection type according to the data transmission and reception method.

The remote control type displays the information stored in the ROM continuously and repeatedly. The PC connection type uses the user interface program provided by the PC operator to display the contents by transmitting real-time data to the display board. The PC-connected electronic display board has the greatest advantage of being able to variously control the display contents such as desired picture, text size, font, thickness, and color using a user interface program, but requires basic knowledge about computer operation. The need for a computer is limited, such as not being used by small businesses. On the other hand, since the remote control type display board is similar to the text message input method of the mobile phone, it is simpler to operate than the PC connection type and can be usefully used in the workplace without a computer. There is a limit.

In addition, the remote control type can control only up to 1 vertical stage, which is composed of several pixel panels connected in the horizontal direction, and can display various graphics, such as displaying larger or smaller letters on two or more display boards. If multiple stages were needed, they could only be controlled by a PC connection.

Therefore, the remote control type can control up to 1 vertical LED display panel, and the multi-stage LED display panel of 2 or more vertical stages can be implemented only by PC connection type.

In addition, in the multi-stage LED display board, even in the case of PC connection type, the multi-stage LED display board having two or more stages should be equipped with a general PC controller up to four stages and use an industrial large controller if the size exceeds four stages. Therefore, since it is necessary to have a suitable controller according to the number, standardization is not easy, and it has to be made to order.

As a result, the conventional multi-stage LED billboard is limited to a customized PC connection type.

Accordingly, the present invention has been made in view of the above problems, and its object is to provide a base LED module control unit controlled by an infrared remote control unit in each stage in the multi-stage LED display board in which the base LED module is vertically connected to two or more stages, and the base The LED module control unit communicates with each other by the unit and controls the base LED module individually or integratedly in conjunction with each other according to the electric signal control signal received from the IR remote controller. The present invention relates to a multi-stage remote control type LED display system and a control method thereof.

In addition, another object of the present invention in the multi-stage remote control type LED display system that is individually or integrally controlled by the infrared remote control, the base LED module control unit converts and stores the video source played through the PC to the minimum capacity and control the infrared remote control The present invention relates to a multi-stage remote control LED display system capable of outputting the same.

In order to achieve the technical problem as described above, the system of the present invention is a multi-stage LED display board, each stage of the electronic board control signal input including a base key for individually controlling the base LED module and an expansion key for integrated control of the base LED module Infrared remote control provided with a function key for receiving, the infrared signal receiving unit converts the infrared signal from the infrared remote control and transmits it to the digital LED module for each stage, and receives the electronic board control signal transmitted by the infrared receiver, Since each base LED module is provided with each other to communicate with each other to perform the step-by-step control or integrated control of the base LED module according to the electronic board control signal, during the integrated control, one is a master module control unit, the other is a slave module control base LED module Control unit, the base LED module control unit Two or more base LED modules, each of which is equipped with a drive drive module for driving pixels by means of a plurality of pixel panels horizontally and vertically connected to each other in a horizontal direction to form a single stage; The infrared receiver, the base LED module controller, characterized in that it comprises a power supply for supplying power to the base LED module.

The base LED module controller converts and stores the video image source that can be implemented through a PC controller to a minimum capacity, and outputs the stored video source to the base LED module by operating an infrared remote controller, and the infrared remote controller is a base LED module. And a video display control key including a display schedule, a display time, and the like of the video through the control unit.

In addition, the control method of the present invention inputs a function key provided on the infrared remote control to transmit the electronic board control signal for inputting and transmitting an electronic board control signal for whether to individually control or integrated control the base LED module provided for each stage In the step, the LED control signal is sent to each base LED module control unit communicating with each other through the infrared receiver and the LED control signal classification step for distinguishing the type of the received LED control signal and if the LED control signal relates to individual control If the base LED module independently drives the base LED module, and integrated control, it characterized in that it comprises a base LED module driving step of integrating the base LED module of each stage to recognize and drive as one base LED module.

Hereinafter, with reference to the accompanying drawings will be described in detail a preferred embodiment of the present invention multi-stage remote control type LED display system and its control method.

1 is a configuration of the present invention multi-stage remote control type LED display board, Figure 2 is a detailed configuration of the base LED module, Figure 3 shows a series of processes according to the control method of the present invention multi-stage remote control type LED display system. Figure 4 is a flow chart showing an embodiment of a control method of the present invention multi-stage remote control type LED display board, Figure 5a and 5b shows a screen example implemented by the present invention multi-stage remote control type LED display board and its control method. 6, 7, 8 are diagrams for explaining the principle that the screen is implemented as shown in Figure 5a, 5b by the present invention multi-stage remote control type LED display board and a control method thereof.

As shown in the drawings, according to the present invention, the multi-stage remote control type LED display system is an infrared remote control 100, an infrared receiver 200, a base LED module control unit 300, a base LED module 400, a power supply unit 500 It is composed.

The infrared remote control 100 transmits the input key signal in the form of an infrared signal as a means for inputting a key for expressing the contents of the electronic display board in various ways. In particular, a function key is provided for inputting an electronic board control signal relating to whether to independently control or integrate the base LED module of two or more vertical stages. The function key is preferably composed of a 'basic control key' for the individual control for each base LED module and 'integrated control key' for integrated control.

The infrared receiver 200 receives the infrared signal transmitted from the infrared remote control 100 and converts it into a digital signal and transmits it to the base LED module controller provided at each stage.

The base LED module controller 300 drives each base LED module according to the key signal received from the infrared receiver. In particular, when the received key signal is a function key signal, that is, an electric sign control signal, it is classified whether it is related to individual control or integrated control and drives the base LED module accordingly. If the LED control signal is a unit control signal, each base LED module is driven independently. If the LED control signal is an integrated control signal, a plurality of base LED modules are controlled under the control of a built-in communication program. One of the base LED module control unit is a master module control unit and the other becomes a slave module control unit to recognize all the base LED module as one stage through interworking. The master module control unit sends a frame start signal to the slave module control unit 1, and the slave module control unit displays an image of frame 1 as soon as the frame start signal is received. Thereafter, the master module controller sends the frame start signal 2 to the slave module controller, and the slave module controller displays an image of frame 2 as soon as the frame start signal 2 is received. In this way, a multi-stage base LED module has the same effect as driving a single LED module as a whole. For example, referring to FIGS. 5A and 5B, the character input through the IR remote control 100 is to be displayed in the case of 'the biggest sale of up to 50% in the future 7 days'. As shown, selecting the stage to display the input character is output by the selected stage. The user can set the display status, format, and method of the characters through the remote control. At this time, the base LED module controller controls the base LED module for each stage, so the set contents are applied to each stage. In addition, in the case of integrated control, as shown in FIG. 5B, since the base LED module control unit interlocks with each other, the characters input by the user are displayed on the entire base LED module, and the display state, format, method, etc. set by the user in this state. This applies.

As shown in FIG. 2, the base LED module has a basic configuration of an LED pixel panel and a driving drive module. In this case, the pixel panel is connected to a number of LED pixels in the horizontal and vertical directions to form one. Usually, it is standardized as a × a. A plurality of LED pixels are fixedly installed on the bottom of the square panel, and a drive drive module is mounted on the rear side of the pixel panel. do. The drive drive module drives the LED pixel panel under the control of the base LED module. Thus, the base LED module is configured by arranging and connecting a plurality of LED pixel panels provided with the drive module in the horizontal direction. And, the base LED module is connected to two or more stages in the vertical direction implements a multi-stage LED display.

The power supply unit supplies power for driving the infrared receiver, the base LED module controller, and the base LED module described above.

In addition, according to the present invention, a specific principle of individually controlling or integrating each stage by a remote controller in a multi-stage LED display is as shown in FIGS. 6, 7, and 8.

That is, as shown in Figure 6, when the six LED panel is displayed on the base LED module consisting of six horizontally connected in the horizontal direction display the contents of the signboard on a single pixel panel because it is basically one character is expressed 'sold sale' In this case, 'large', 'night', 'three' and 'day' are displayed on one pixel panel.

However, according to the present invention, as shown in FIG. 7, when the integrated control signal is input through the function key of the remote control in the multi-stage LED display panel configured by vertically connecting the base LED module of FIG. Since the contents of the display board displayed are displayed on the four pixel panels, the contents of the display board are enlarged. It may also be displayed on two pixel panels, as shown in FIG.

On the other hand, the control method of the multi-stage LED signboard system of the present invention includes a signboard control signal transmission step, a signboard control signal classification step and the base LED module driving step.

That is, the step of transmitting the sign control signal is a step of inputting and transmitting a sign control signal for setting whether to individually control or integrated control the base LED module through a key input unit provided on the remote controller.

In addition, the display board control signal classification step, the display board control signal transmitted from the remote control is transmitted to each base LED module control unit via a receiving unit, and distinguishing which control signal corresponds to either the individual control panel or integrated control. It's a step.

In the driving step of the base LED module, each base LED module controller independently drives the base LED module when the divided LED control signal is an individual control, and the base LED module is interlocked with each other between the base LED module controllers in the case of integrated control. Recognizing and driving as a module.

A preferred embodiment thereof is described with reference to FIG. 4 as follows.

That is, first, a user inputs contents to be displayed on the electronic display board through a remote controller. Next, enter a function key for setting whether to output the contents in each stage or to output the contents in a unit. Then, the key signal input in this way is transmitted in the form of an infrared signal and transmitted to the base LED module control unit via the infrared receiver. Subsequently, the base LED module control unit that interoperates with each other distinguishes the type of function key signal, that is, the electronic sign control signal. That is, the base LED module is divided into individual control or integrated control according to the electric sign control signal.

Then, when the divided signal is an electric sign control signal for individual control, the input contents are output for each stage and the contents are individually controlled by the remote controller. For example, the contents of the upper stage can be stopped and the contents of the lower stage can be moved.

In addition, when the divided signal is an electronic sign control signal for integrated control, the input contents are output through the entire stage to derive an enlargement effect of the contents. And, the content output in this state can be expressed in various ways by the remote control method.

Therefore, according to the present invention, such as Korean characters, English letters, Japanese, various figures, numbers, symbols, various characters, character thickness control, blinking inversion, screen inversion, speed control, 2D graphics, 3D animation, etc. Format, move up, move down, laser function, more than 28 expressions such as 360 ° rotation, move left and right, current time function, ON / OFF timer function, full phrase transmission function, specific phrase transmission function, order change It can control display performance such as function, each room delete function, phrase edit function, remote control function, and up to 128 characters including Korean characters (English, Japanese, numbers, symbols), 1 ~ 99 rooms, 1 space All these functions can be expressed in each stage or can be expressed throughout the stage.

In addition, according to another embodiment of the present invention, the base LED module control unit converts and stores the video source that can be implemented through a PC to a minimum capacity, and outputs the stored video source to the base LED module by an infrared remote control operation. The infrared remote control further includes a video display control key including a display schedule display time of a video through the base LED module controller.

That is, the base LED module control unit includes a conversion program for converting a video source that can be implemented using a PC as a medium into a minimum capacity, and the converted video source is stored in the base LED module control unit by an infrared remote controller. It is displayed on the base LED module according to the sent video display control signal. Here, the video display control key provided in the infrared remote control is configured to set the display schedule and the display time of the video output through the base LED module.

Therefore, since the implementation of the video through the display board is limited to the large display board controlled by the large PC controller, it is necessary to display the image source in real time through the PC or to repeatedly display the image source stored in the hard disk. And because the image medium must be provided in the small display board controlled by the remote control overcomes the conventional limitation that could not implement the video.

As described above, the present invention communicates between a plurality of base LED module control units provided in each stage in the multi-stage LED display board and independently interlocks and controls each stage according to whether a function key is input through the remote controller. It can be implemented by a remote control method to overcome the limitation that was limited to the conventional PC connection type.

In addition, in the conventional PC-connected type, by implementing a multi-stage LED signboard, the contents of the signboard could be displayed in various ways, but the PC was able to be installed and skilled computer-based knowledge was required to limit its installation location and use. However, according to the present invention, in accordance with the present invention, a multi-stage LED display is controlled by a simple operation using a remote controller similarly to a mobile phone input method, so that various characters can be expressed such as enlargement or reduction of character size. While the effect is similar, the operation method is simple, thereby maximizing the commerciality and advertising effect.

In addition, if a conventional multi-stage LED signboard is to be implemented, a separate controller for controlling the multi-stage LED signboard must be provided. At this time, a very high performance is required to control all the multi-stage LED signboards. It was not easy to control by the infrared remote control method. However, according to the present invention, since the base LED module control unit provided with each base LED module interlocks with each other, the same effect as controlling with one controller is possible, so that simple control is possible by a remote control method without increasing the production cost. While increasing productivity and lowering the production stage, the advertising effect can be obtained in the same way as that of a conventional PC connection type.

That is, by using the standardized base LED module control unit, the multi-stage LED display board can be controlled by the remote control method, so it is possible to respond more quickly to the demands of the orderer when producing the LED display board. The effect is very large.

On the other hand, according to another embodiment of the present invention, since the base LED module control unit can store a video source that can be implemented through a PC with a minimum capacity and output it under the control of an infrared remote control, the electronic display board that the conventional video is displayed is expensive Since a PC or an image medium must be provided, it overcomes the limitation that was difficult to implement in a low-cost small electronic display board.

Although the present invention described above has been described in detail only with respect to the specific examples described, it will be apparent to those skilled in the art that various modifications and changes are possible within the technical scope of the present invention, and such modifications and modifications belong to the appended claims. will be.
