Receives data (Sign data) and operates on and off in response to a corresponding address and pulse, and each module 11 receives an LED by receiving a DC power through an internal SMPS as described above. A larger capacity SMPS 13 may be used for driving or supplying DC power to each module as indicated by hatching.

LEDs are said to use red mainly due to price issues. Therefore, in order to display the three primary colors of light, both green and blue should be used. However, when green and blue are used to fabricate one electric signboard, the unit price increases exponentially. There will be little economy.

Therefore, there is an urgent need to secure the technology of the module and the electronic display board using the LEDs using green and blue LEDs other than red while improving the color realization capability and securing price competitiveness.

The present invention has been proposed to solve the conventional problems as described above, by using a variety of light emitting diodes, such as green and blue in addition to red to improve the color implementation ability while reducing the production price to secure a price competitiveness It is an object of the present invention to provide a display board module and an information display board using the same.

The present invention for achieving the above object, a substrate; A plurality of first light emitting parts disposed on the entire surface of the substrate to emit light of a first color; At least one second light emitting part disposed on a rear surface of the substrate to emit light of a second color; And a light transmitting unit for allowing the light output from the second light emitting unit to be output through the front surface of the substrate.

In addition, the present invention for achieving the above object is a panel in which a plurality of the above-described module for an electronic board is arranged; And a microcomputer for controlling on-off and timing of the first to third light emitting units of the respective light emitting module for displaying the received information through the panel.

Although it is possible to realize green and blue LEDs among the three primary colors of light, its production cost is higher than that of red, so it cannot be used in the area where multiple LEDs are used, such as electronic signboards. Only LEDs have been used.

However, in the present invention, green and blue LEDs are applied to such an electronic board at a relatively low price. For this purpose, the number of red LEDs required for one module is used and placed on the front of the substrate such as a PCB. The green and blue LEDs use a minimum number (one or two) of each. At this time, a minimum of blue and green LEDs are disposed on the back side of the substrate, and a photo delivery ring for transferring the light output therefrom is arranged, and the light transmitted from the photo delivery ring is transferred to one side of the plurality of optical fibers. It receives through the input, and outputs the light through the other side of the plurality of optical fibers disposed in front of the substrate.

That is, by using only a minimum of blue or green LEDs per module for one display board, it is possible to output the same number of lights as red, so that the three primary colors of light can be realized through the display board at a relatively low price.

Hereinafter, the most preferred embodiments of the present invention will be described with reference to the accompanying drawings so that those skilled in the art can easily implement the technical idea of the present invention.

4 is a block diagram showing a module for an electronic board according to a first embodiment of the present invention.

Referring to FIG. 4, the module for an electronic board includes a substrate 40 such as a PCB, a plurality of red LEDs 41 disposed on the front surface of the substrate 40, and a green LED 45 disposed on the rear surface of the substrate 40.

A protective filter covering the front surface of the substrate 40 to protect the red LED 41 and the optical fiber 43 for outputting light through its other end 43b disposed on the front surface of the substrate 40. It is comprised with 42 and the module case 47.

Here, the light delivery ring 44 and the optical fiber 43 serve as a light transmission unit, and a plurality of lights are directed to the front surface of the substrate 40 using only the green LEDs 45 and the blue LEDs 46 each used one by one. To output it.

Although not shown in the drawings, the module may include an SMPS, and a plurality of modules may be supplied with DC power through one large-capacity SMPS without having an SMPS for each module.

In the first embodiment illustrated in FIG. 4, one green LED 45 and one blue LED 46 are used, respectively, but both reference numerals 45 and 46 may be used as blue LEDs or green LEDs. have.

In FIG. 4, for example, 256 red LEDs 41 disposed on the front of the substrate 40 output red light, for example, each of the 256 optical fibers 43 has a ratio of blue to green through one end 43a. Since the different light is output to the front of the substrate 40 through its other end 43b, the light output from the front of the module outputs light including all three primary colors of red, green, and blue.

Thus, the relatively expensive blue and green LEDs use only one or two of each module and replace the blue and green LEDs through a relatively inexpensive optical fiber, thereby significantly reducing module production costs.

On the other hand, the red and green LEDs may be used separately, respectively, Figure 5 is a schematic diagram showing a module for an electronic board according to a second embodiment of the present invention.

A blue LED 49 disposed in isolation from the LED 48, a photo delivery ring 44 " receiving blue light output from the blue LED 49, and a blue light transmitted from the photo delivery ring 44 ". And an optical fiber 43 "for outputting blue light through its other end 43b" disposed on the front surface of the substrate through its one end 43a ".

Here, the red LED disposed on the front surface of the substrate, the protective filter covering the front surface of the substrate to protect the red LED, and the module case are omitted.

That is, in the second embodiment, the green LED 48 and the blue LED 49 are isolated from each other, and their optical fibers are also used separately. In this case, the cost is almost twice that of the first embodiment, but on the other hand, there is an advantage that the color implementation ability can be further improved.

Meanwhile, only one blue or green LED may be used. FIG. 6 is a configuration diagram schematically illustrating a display board module according to a third embodiment of the present invention.

Referring to FIG. 6, the module for the electronic display board includes a blue or green LED 50 disposed on the back of the substrate, a photo delivery ring 44 receiving green light output from the LED 50, and a photo delivery ring 44. It is configured to include an optical fiber 43 for receiving the light transmitted from its own through one end (43a) and outputs the light through its other end (43b) disposed on the front of the substrate.

Here, the red LED disposed on the front surface of the substrate, the protective filter covering the front surface of the substrate to protect the red LED, and the module case are omitted.

That is, in the third embodiment, only one LED 50 of green or blue is used. In this case, the color implementation ability is reduced compared to the first and second embodiments, but it may be more economical when used as a limited use requiring only blue and red or green and red.
