The embodiment relates to an electric sign board module.

In general, it is well known that the outdoor electronic display device is widely used as a means for delivering text and images to an unspecified number using a single medium. The application range of the outdoor billboard is gradually expanded and widely used as a large guide plate of a playground, a traffic information guide plate of a road, an outdoor billboard, and the like.

Large-scale rooftop advertisements used as outdoor advertisements include billboards, Panaplex, and Trivision, and large LED advertisements have recently been introduced. Such LED (LED) -type advertising is used to implement a dynamic image to increase the advertising efficiency. A number of high-brightness LEDs are mounted in a predetermined matrix form to turn on and off each LED through X, Y axis control of the matrix. At this time, the matrix is capable of large-scale video advertising due to the fast response time of the LED, and the frequency of use is increasing because the color conversion is free.

The embodiment provides an electric sign board module that automatically inputs coordinate information of each module.

The embodiment provides an electronic display module that can automatically input coordinate information after checking its ID upon receiving an external command.

According to an embodiment of the present invention, there is provided an electronic display module comprising an array of n modules, each module including: a logic unit configured to store parameters for setting identification numbers and coordinate information of each module; An LED unit including a plurality of LEDs; And controlling the respective units and setting the coordinate information of each module by using the stored identification number and the parameter.

The embodiment can reduce the time and cost according to the manual coordinate input of each module of the display board.

In an embodiment, each module automatically inputs coordinate information, thereby reducing errors in coordinate input.

The embodiment can improve the reliability of the LED module.

Hereinafter, with reference to the accompanying drawings as follows.

1 is a view showing a module-to-module connection method according to an embodiment, Figure 2 is a view showing a detailed configuration of the module according to the embodiment, Figure 3 is an initial state to each module of the sign according to the embodiment 4 is a diagram illustrating a coordinate input state to each module of the electronic display board according to the embodiment.

Referring to FIG. 1, the electric sign board module 100 includes n modules 101 to 10n, and the n modules 101 to 10n are connected in series with adjacent modules. That is, the second module 102 is connected to the first module 101, the third module 103 is connected to the second module 102, and n modules 101 to 10n are serially connected in this manner. Can be connected to.

The n modules 101 to 10n are configured as M * N sign board modules to display an image.

Each of the n modules 101 to 10n is assigned its own unique identification number (ID), and can communicate with its own identification number. In this case, the identification number is assigned to the first module 101, the second module 102, the second module 102, the third module 103, and so on in order. The nth module 10n from the first module 101 stores its own unique identification number through communication with adjacent modules.

Referring to FIG. 2, each module 101, 102, 103 of the electronic sign module 100 includes a microcomputer 111, a logic unit 113, and an LED unit 115, and the microcomputer 111 includes the logic unit 113. Information is read and written to the LED, and the driving of the LED unit 115 is controlled.

The microcomputer 111 of the first module 101 communicates with the microcomputer 111 of the adjacent second module 102 and is controlled by a computer PC. The first module 101 may communicate with the computer 120 in an RS-232 or controller area network (CAN) manner.

The computer 120 may be included in a component of the sign board module 100 or may be separately configured. In addition, the computer 120 may be connected to the n modules (101 ~ 10n) in the communication method as described above.

The logic unit 113 may be implemented with, for example, a field programmable gate array (FPGA). The logic unit 113 stores a parameter for setting coordinate information together with the identification number ID.

The parameter includes at least one of module position information, module matrix information (M * N), and module pixel information. The module position information is coordinate information of a position where each module is disposed, and the matrix information corresponds to information on rows and columns of the entire display board. The module pixel information indicates the number of pixels displayed in the module. Here, the matrix information may be used as last module position information.

Here, the identification number assignment method of each module (101, 102, 103) is as follows.

Logic units 113 of the modules 101, 102, and 103 are connected to each other through the microcomputer 111 when adjacent modules are connected in series. At this time, the logic unit 113 of each module (101, 102, 103) is to pass its identification number (ID) to the logic unit 113 of the other module, respectively.

For example, when the identification number is set to 1 in the logic unit 113 of the first module 101, the logic unit 113 of the second module 102 may be configured as the logic unit of the first module 101. Receiving the identification number information set to 1 from 113 to set the identification number to 2, the logic unit 113 of the third module 103 is the logic unit 113 of the second module 102 Receive identification number information set to 2 from) and set the identification number to 3. In this way, n modules can set their module identification number. In addition, since each module is connected in series with each other, it is possible to prevent the identification number from being duplicated by notifying the connected module of its identification number when another module is additionally connected.

The logic unit 113 stores a unique identification number (ID) of each module (101, 102, 103). Here, the microcomputer 111 may analyze its own control signal through the identification number stored in the logic unit 113.

The arrangement of the modules 101, 102, and 103 may be variously designed. For example, it may be arranged in the horizontal direction or in the vertical direction, or may be arranged in a zigzag manner. In this case, even if the arrangement is changed in various ways, the modules 101, 102, and 103 having adjacent identification numbers are disposed adjacent to each other up and down and / or left and right.

For example, as shown in FIG. 3, 24 modules (Module 1 to 24) are disposed in the signboard module 100. The arrangement of each module (Module 1 to 24) is, for example, from the lower end of the left end. One module (Module 1) is disposed, the second module (Module 2), the third module (Module 3) is disposed in the vertical upward direction, the fourth module (Module 4) to the right again, the fifth in the vertical downward direction The modules are arranged in the order of the module 5 and the sixth module 6.

In addition, in addition to the module arrangement method as shown in FIG. 3, it may be arranged in a vertical direction from the left end, or may be arranged in a horizontal direction from the left end (or below), and this arrangement structure may be variously changed. It does not limit to this.

In addition, each module (Module 1 ~ 24) is initially in a state that the coordinate information is not set. That is, initially, all modules (Module 1 to 24) can be set to the coordinate information (00,00).

Even though each module (Module 1 ~ 24) is arranged in the order of the identification number, since it does not always match the actual coordinate information, the module position information, module matrix information (M * N: 3) with the identification number 8), coordinate information of each module (Module 1 to 24) is set using the module pixel information. The coordinate information may be used to control pixel operation of each module.

Referring to FIG. 2, since the identification number, module position information, module matrix information, and module pixel information are stored in the logic unit 113, the microcomputer 111 of the first module 101 is connected to the computer 120. When the coordinate setting command is received from the control unit, the identification number, the module position information, the module matrix information, and the module pixel information are read through the logic unit 113. The microcomputer 111 determines the number of pixels of the module and sets coordinate information according to the module position information and the module matrix information. In this way, the n modules can set the coordinate information, respectively.

Therefore, as shown in FIG. 1, when the display board module is composed of n modules 101 to 10n, the computer 120 transmits a command for setting coordinate information to the first module 101. At this time, the microcomputer 111 of the first module 101 uses the identification number, module position information, module matrix information, and module pixel information stored in the logic unit 113 to determine the position of the first module 101. Set the coordinate information.

Referring to FIG. 4, when each module (Module 1 to 24) receives a coordinate setting command, each module (Module 1 to 24) has its own identification number and uses the module position information, module matrix information (M * N), and module pixel information to obtain coordinate information. Each will be set automatically.

Here, each module (Module 1 ~ 24) is composed of 32 pixels, the module matrix information is 8 * 3, the coordinate information is displayed in hexadecimal. The hexadecimal display method is an example and may be changed in other ways.

Since the position information of the first module (Module 1) is 1 column and 3 rows, the coordinate information is set to (00,40), and the position of the second module (Module 2) is 1 column and 2 rows, so the coordinate information Is set to (00,20), and the third module (Module 3) has position information of one column and one row, so the coordinate information is set to (00,00). In this way, coordinate information may be set in order for all 24 modules. When inputting the leftover information, a range of coordinate information of each module may be set through module matrix information indicating a last row and a last column.

In addition, when each of the 24 modules is connected to the computer, the coordinate information of the 24 modules may be set at the same time.

By transmitting a driving signal to each module according to the coordinate information set as described above, each module is driven correctly, and an image such as an advertisement may be displayed.

5 is a flow chart illustrating a coordinate input method of an electronic display module system according to an embodiment.

Referring to FIG. 5, when the command is received (S101), the microcomputer of each module checks whether the command is the coordinate setting command (S103). If the check result is a coordinate setting command, after checking at least one of an ID of the module, module position information, module matrix information, and module pixel information (S105), coordinate data corresponding to the ID is automatically set (S107). ).
