BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an LED display device for displaying characters or figures by causing an LED to emit light.

[0002]

2. Description of the Related Art Conventionally, in an LED panel in which LEDs are appropriately mounted on a mounting portion according to display contents such as characters and figures, and an LED display device using the same, a specific character to be displayed is displayed. Alternatively, an LED panel (hereinafter referred to as a fixed LED panel) in which a board pattern is individually created for each graphic and LEDs are arranged is created for each specific character or graphic, and a single character or graphic is displayed. It was For example, in the case of an LED display device that wants to display the character "A", a fixed LED panel in which LEDs are arranged according to the character display "A" has been prepared. Also,
Display the two characters "A" and "I" by displaying the character "A" for a predetermined time, and then after displaying the character "A", display the character "A" for a predetermined time. There is known an LED display device that repeatedly displays the character "a" again for a predetermined time after the display of the character "a" is completed. If you want to switch between these two displays, use 1 according to the character display of "A" and "I".
A two-system fixed LED panel in which LEDs are arranged on one panel is prepared. However, in such an LED panel, a fixed LED panel must be prepared for each character or figure to be displayed. If there is no fixed LED panel for the character or figure to be displayed, or if the character or figure to be displayed is When it is desired to add another character or figure to a fixed LED panel such as a figure to be displayed, the fixed LED panel had to be made again according to each display content.

On the other hand, there is known an LED panel in which a large number of LED mounting portions are arranged in a matrix (hereinafter referred to as a multi-LED panel) so that arbitrary characters or figures can be freely formed. . However, in such a multi-LED panel, there has not been seen a fixed LED panel in which two characters or figures are switched and displayed in a lit state.

[0004]

[Problems to be Solved by the Invention] Such multi-LE
In the LED display device using the D panel, it is not necessary to prepare a fixed LED panel for each character or figure to be displayed, and it is an advantage that an LED display device with reduced development cost can be provided. On the panel, there is a drawback that two arbitrary characters or figures cannot be switched on and displayed. In the present invention, an LED that can freely form any character or figure and can switch and display two arbitrary characters or figures, etc.
It is an object of the present invention to provide an LED panel in which a large number of mounting parts are arranged in a matrix, and an LED display device using the same.
