[Prior art]

 An LED is a crystal having a PN junction. When a forward voltage is applied, electrons move from the N region and holes move from the P region to the PN junction. When the electrons and holes recombine, a narrow frequency band is used. Generates almost monochromatic visible light. Since the power consumption of LED lamps is lower than that of general fluorescent lamps, it has excellent durability and the wear rate of parts is relatively low. At present, LEDs that emit light of various different colors have already been manufactured and To generate different colors. In addition, LEDs have high brightness and stable chromaticity, fast switching speed, and high afterimage effect on vision, so LEDs are widely used for display elements of large display panels and dynamic image display panels.

A lamp 60 and a case 70 are provided. The plurality of LED lamps 60 are placed on one substrate 80, and a signal input from the drive circuit board 30 is transmitted to the substrate 80 via a conductor 90, further transmitted to each LED lamp 60, and separately provided in another space in the case 70. Filled with a suitable filler 92, such as an epoxy resin, to form an effective insulating structure, protect the internal power distribution circuit, can be used in outdoor environments for a long time, and can prevent damage from sunlight and rain. It is so.

[0004] The CPU 10 generally receives an image signal transmitted by an RS232 or other conversion transmission interface, appropriately processes VGA / SVGA or other types of image data, and then processes the resulting data into respective data. It is sent to the module controller 20 to control the drive circuit board 30 corresponding to each module controller 20. The drive circuit boards 30 are connected in series, so that the signal transmitted from the first drive circuit board to the next drive circuit board is further transmitted to the next drive circuit board. Each driving circuit board 30 drives a corresponding LED dot matrix group 40, and the LED dot matrix group 40 generally includes a plurality of LED dot matrices 50 arranged in a plane, and this matrix arrangement forms a rectangular display element. And the rectangular plates of the LED dot matrix group 40 are combined in different shapes.

The above-described conventional LED dot matrix display system requires an independent driving circuit board 30, and the driving circuit board 30 controls the lighting operation of each LED lamp in the LED dot matrix group 40. Therefore, the entire combination structure becomes complicated, and the occupied space becomes large, which is inconvenient for application to a large display panel.Moreover, since the number of constituent elements is large, the frequency of repair increases, and the working time for use increases. The impact has occurred and the overall efficiency has been reduced.

For this reason, there has been a demand for an LED dot matrix display system having a simple structure, convenient for repair, and having a small number of components, and a structure of an LED dot matrix that enables the display.

[0007]

[Problems to be solved by the invention]
